Description

  The present invention relates to an electric heater that sucks air from the outside of a housing to form a flow of warmed air (warm air) and blows the warm air in a specific direction, and particularly heats the sucked air. The present invention also relates to an electric heater that humidifies the air.

  Various types of electric heaters are known as electric heaters used for indoor heating. Among these, in the "blower type" electric heater that prepares a flow of warmed air (warm air) by sucking air from the outside and warming it, A configuration including a mechanism (humidifying unit) that not only warms but also humidifies air is also known.

  For example, Patent Literature 1 discloses an electric heater including a remote controller having a temperature sensor and a humidity sensor, and a control unit that receives a signal from the remote controller and controls a heating element and a humidifier. . According to the cited document 1, since the electric heater is configured to detect the temperature and humidity near the user, it is controlled to the temperature and humidity that the user feels comfortable, and the heating to the user is comfortable. It can be done efficiently. In Cited Document 1, the specific configuration of the humidifier (humidifier) is not particularly limited.

  Patent Document 2 discloses a main body block including a blower unit that discharges air from a discharge port and a heating unit that heats air, and an electrostatic mist that generates nanometer-sized ion mist and discharges it from the mist discharge port. There is disclosed a heating air blower that is configured so that the discharge direction of ion mist is substantially parallel to the discharge direction of air from the discharge port in the main body block. And according to patent document 2, it is supposed by the said structure that ion mist rides on the flow of the air discharged from the main body block, and is rapidly delivered to a target object in large quantities.

  Further, Patent Document 3 includes a main body block and an electrostatic atomization block, and a heat radiation channel is branched from a main air flow channel of the main body block, and the heat radiation channel is a heat radiation which the electrostatic atomization block has. Further, there is disclosed a heating air blower having a configuration in which the heat dissipation flow path is branched into a first branch flow path and a second branch flow path. The first branch flow path is a flow path that passes through the discharge electrode of the electrostatic atomization block and communicates outward, and the second branch flow path bypasses the discharge electrode and moves outward. It is a channel that leads to According to Patent Document 3, with the above-described configuration, the flow rate of the airflow flowing through the heat dissipation channel to the discharge electrode can be reduced, and the discharge electrode is heated by the airflow, so that generation of nanometer-sized ion mist is not caused. It is said that it can suppress becoming stable.

  In addition, the structure provided with an electrostatic atomizer as a humidification part is known also in the heater which prepares warm air by burning a fuel instead of an electric heater. For example, Patent Document 4 discloses an electrostatic atomizer that electrostatically atomizes water held in a discharge part of a discharge electrode to generate charged fine particle water, and a supply unit that supplies the generated charged fine particle water to an air passage. There is disclosed a fan heater comprising: According to Patent Document 4, charged fine particle water having a high deodorizing effect and sterilizing effect generated by an electrostatic atomizer can be supplied to an air passage during a heating operation of a fan heater and before and after the heating operation. It is said that charged fine particle water can be widely spread indoors by being blown by a fan.

  However, in the electric heater disclosed in Patent Document 1, there is a possibility that the moisture of the skin is not sufficiently satisfied for the user. Specifically, in the electric heater having the above-described configuration, the temperature and humidity that the user feels comfortable are controlled, so that humidification is performed during heating, preventing a state of excessive drying and a comfortable heating environment. Is possible. However, even if the indoor humidity to be heated is appropriate, in a situation where the warm air directly hits the user's skin or the like, there is a possibility that the warming of the skin may be hindered by the warm air.

  On the other hand, in the configurations disclosed in Patent Documents 2 and 3, that is, in the configuration including the electrostatic atomization block, the warm air is blown from the blower and the electrostatic atomizer is generated. The ion mist is discharged from the ion discharge port. For example, as described in Patent Document 2, ion mist can exert effects such as moisture retention.

  However, the heating air blower specifically disclosed in Patent Documents 2 and 3 is a dryer, and it is simply described that it can be applied to a fan heater other than the dryer. The main purpose of the dryer is to dry the air blowing target such as hair, while the main purpose of the electric heater is to warm the room. Therefore, in order to apply the techniques disclosed in Patent Documents 2 and 3 to an electric heater, it is necessary to devise a configuration of an electrostatic atomization block or the like so that it can cope with indoor heating.

  Here, in the fan heater disclosed in Patent Document 4, the electrostatic atomizer generates charged fine particle water and distributes it widely in the room, thereby deodorizing living odors in the room, viruses, allergens, and molds. And odors caused by inactivation of general live bacteria, fuel contained in the air blown into the room from the hot air outlet, and incomplete combustion of the fuel. That is, the electrostatic atomizer disclosed in Patent Document 4 has both a function as a “humidifying part” and a function as a “deodorizing part”, but as disclosed in Patent Documents 2 and 3, It is not used as a configuration for achieving moisture retention or the like of the air blow target.

  The present invention has been made to solve such a problem, and not only enables heating at a desired temperature, but also makes it possible to moisturize the user's skin and the like. An object is to provide an electric heater.

In order to solve the above-described problems, the electric heater according to the present embodiment includes a housing provided with an air inlet, a first air outlet, and a second air outlet adjacent to the first air outlet, and the air intake. A blower that sucks air from the mouth into the housing and blows air toward the first and second air blowing ports, and blows air blown toward the first air blowing port from the first air blowing port. A heating unit that warms before, an atomized air generating unit that prepares atomized air by including fine particles of charged water in the air that is blown toward the second blowing port, and the blowing leads to the second air blowing port from parts, and, and a atomization air blowing duct for blowing toward the atomizing air adjusted by the atomizing air generating unit to the second air blowing port, the second blower The flow rate of the atomized air blown from the mouth is the flow rate of the warm air blown from the first blower port. Ri is a configuration that is a high speed.

According to the said structure, since atomization air is ventilated by the atomization wind ventilation duct to the 2nd ventilation port so that it may have directivity, the flow (mist) of atomization air which has directivity from the said 2nd ventilation port Breeze). Here, the second air outlet is adjacent to the first air outlet, and since the air flow (warm air) heated by the heating unit is blown out from the first air outlet, the atomized air is adjacent to the hot air. It is blown out in the form to do. At this time, since the atomizing wind is given directivity by the atomizing air blowing duct, it can be merged at a position away from the housing by a predetermined dimension without immediately mixing with the warm air. As a result, the warm air merges with the atomized wind in a state where the temperature is lowered to some extent, so that the charged water fine particles (charged fine particle water) contained in the atomized wind are greatly lost due to the heat of the warm air. It reaches to a predetermined position without. Therefore, even when warm air directly hits the user, the user can obtain warmth by the warm air and can also obtain a moisturizing effect on the skin by the charged fine particle water.
And according to the said structure, since the flow velocity of warm air and atomization wind differs, these air flows have the tendency which one side is attracted to the other by the difference in flow velocity. Here, since the atomized wind has a higher flow velocity than the warm air and has high directivity, it is not easily mixed with the warm air immediately after blowing, and the warm air is the first. There is a tendency to form an updraft while the temperature decreases immediately after blowing from the blower opening. Therefore, due to the high flow rate of the atomizing wind, the atomized wind having high directivity is not affected by the heat from the warm air, and is drawn to each other while traveling a certain distance. Can be joined.

  In the electric heater configured as described above, it is preferable that the atomizing air blowing duct is configured to have a shape in which a cross-sectional area gradually decreases toward the second air blowing port.

  According to the said structure, since the atomization wind ventilation duct becomes a structure narrowed down toward the front-end | tip (2nd ventilation opening), the flow velocity of the atomization wind which flows through an atomization wind ventilation duct rises. Therefore, the atomized wind blown out from the second blower port is not only given directivity in the blowing direction but also has a high flow velocity. Therefore, the atomized wind can reach a predetermined position without being mixed with the adjacent warm air immediately after blowing. As a result, the user can obtain warmth by warm air, moisturizing effect, and the like.

  In the electric heater having the above-described configuration, it is preferable that the atomized air generation unit is provided in the atomized air blowing duct.

  According to the said structure, since the arrangement | positioning area | region of an atomization air production | generation part and an atomization wind ventilation duct overlaps in a housing | casing, while being able to reduce a housing | casing further, an air flow is carried out with respect to the atomization air production | generation part from a ventilation part. Can be suitably derived.

  In the electric heater configured as described above, it is preferable that an opening area of the first air outlet is larger than an opening area of the second air outlet, and the first air outlet is provided on the lower front side of the housing. It is more preferable that the second air outlet is provided adjacent to the upper side of the first air outlet.

  If the opening area of the first air outlet that blows warm air is large, the warm air can be blown out in a larger amount than the atomized wind, so it is more efficient to heat the room or give warm air to the user. Can be done automatically. In addition, since the charged fine particle water contained in the atomized wind is not required in large quantities, an increase in the size of the housing can be avoided if the opening area of the second air outlet that blows off the atomized wind is reduced. be able to.

  Further, as a relative positional relationship, if the first air blowing port is located on the lower side of the housing and the second air blowing port is located on the upper side of the housing, the hot air having a relatively large flow rate, high temperature and low directivity is provided. Blows from the lower side, and a relatively small flow rate, low temperature, and highly directional atomized wind blows from the upper side. As a result, the warm hot air gradually rises and gradually approaches the atomized wind, but the atomized wind is highly directional even at a small flow rate. Can be merged at a predetermined position after a certain amount of progress.

  The electric heater configured as described above preferably further includes a wind direction adjusting member provided between the first air outlet and the second air outlet.

  According to the said structure, since the wind direction (blowing direction) of warm air or atomization wind, or both of these air flows can be adjusted, the stability of the position where these air flows merge can be improved. Further, if the wind direction adjusting member is movable, it is possible to change the merging position of each air flow by changing these positions.

In the electric heater having the above-described configuration, the upper surface on the inner side when viewed from the second air outlet in the atomizing air blowing duct is higher than the upper end of the opening of the second air outlet. At the same time, the lower surface is preferably flat in the horizontal direction .

According to the said structure, the flow velocity of the atomization wind which blows off from a 2nd ventilation port becomes comparatively large compared with the case where a 2nd duct does not exist. Here, the second air blowing port is adjacent to the first air blowing port, and the warm air blown out from the first air blowing port has a flow rate larger than that of the atomized air, but has a relatively high speed. The atomized wind is avoided from being mixed with warm air having a large flow rate at a position immediately after blowing. Therefore, the warm air and the atomized air can be merged at a position away from the housing by a predetermined dimension without being mixed immediately .

  In the electric heater having the above configuration, the configuration of the atomized air generation unit is not particularly limited, but an electrostatic atomization unit that generates fine particles of water from moisture contained in the air blown from the blower unit is preferable. Can be mentioned.

  In the electric heater having the above-described configuration, it is preferable that the electric air heater further includes at least a hot air blowing duct connected to the first air outlet from the heating unit, and the first air via the hot air air duct from the air blowing unit. It is more preferable to further include a humidifying unit that humidifies the airflow blown toward the blower opening.

  According to the said structure, since a warm air ventilation duct will extend from a ventilation part in parallel with an atomization wind ventilation duct, these may mix in a housing | casing until warm air and atomization wind blow off. Can be avoided. Moreover, since the warm air which flows through a warm air ventilation duct can be humidified and blown out by providing the said humidification part, a humidification function can be given to the electric heater of this invention.

  As described above, according to the present invention, it is possible to provide an electric heater that not only enables heating at a desired temperature but also allows moisture to be given to a user's skin and the like. Play.

The humidifying unit 15 humidifies the airflow blown from the blower unit 12 through the first duct 18 toward the first blower port 17. In the present embodiment, the humidifying unit 15 is not provided inside the first duct 18, and the humidifying unit storage chamber 35 is located on the lower side of the first duct 18. It is provided at a remote location.

  As described above, the humidifying part storage chamber 35 is provided adjacent to the lower side of the first duct 18, and the openable opening / closing lid part 14 is provided between the humidifying part storage chamber 35 and the first duct 18. Is provided. In the present embodiment, the opening / closing lid portion 14 is configured in a door shape that opens and closes around a rotation axis.

  As shown in FIG. 7, in the present embodiment, the position between the heating section storage chamber 33 (or the position where the heating section 13 is provided) and the first air blowing port 17 in the first duct 18, For example, the first duct 18 and the humidifying portion storage chamber 35 are communicated with the lower surface of the position where the vertical portion and the horizontal portion of the first duct 18 are connected (that is, the lowermost surface of the vertical portion of the first duct 18). A humidification path inlet 51, which is a communication port, is provided. The humidification path inlet 51 is opened when the opening / closing lid 14 is moved upward, and is closed when the opening / closing lid 14 is moved downward.

  Further, in the first duct 18, the position on the downstream side in the air blowing direction when viewed from the humidification path inlet 51, in the present embodiment, for example, on the lower surface of the rear end side of the lateral portion of the first duct 18, A duct junction 52 is provided. Similarly to the humidification path inlet 51, the first duct junction 52 is a communication port that communicates the first duct 18 and the humidifying portion storage chamber 35. However, a member that opens and closes the first duct junction 52 is provided. It is not open and always remains open.

  In addition, the positional relationship between the humidification path inlet 51 and the first duct junction 52 is such that the humidification path inlet 51 is on the upstream side in the blowing direction between the heating unit storage chamber 33 and the first blower port 17. If the 1st duct junction 52 is located in the downstream of the ventilation direction, the specific position will not be limited. That is, the humidification path inlet 51 may be a branch path inlet that branches from the hot air blowing duct (in this embodiment, the first duct 18) to the humidification path, and the first duct junction 52 extends from the humidification path. A branch path outlet that flows into the hot air blowing duct may be used.

  As shown in FIG. 7, when the open / close lid 14 is closed, the air flow from the blower 12 is directly blown toward the first blower port 17 without passing through the humidifier 15. On the other hand, as shown by a two-dot chain line in FIG. 7, in a state where the opening / closing lid 14 is open, the air flow from the air blowing unit 12 flows in the humidifying part storage chamber 35 as indicated by the two-dot chain line arrow Ah in the drawing. Then, the air is supplied to the first air outlet 17 through the first duct junction 52 after being humidified by the humidifier 15. Therefore, the humidifying part storage chamber 35 is a bypass path as viewed from the first duct 18 and is a path for humidifying the warm air generated through the heating unit 13, and can be referred to as a “humidification path”. . Further, the opening / closing lid 14 and the humidification path inlet 51 are configured to introduce or block warm air from the first duct 18 to the humidification path, and thus can be referred to as a “humidification path opening / closing section”.

  Here, the positional relationship among the motor chamber 30, the blower fan chamber 31, the heating unit storage chamber 33, the electrostatic atomization unit storage chamber 34, and the humidification unit storage chamber 35, which are a section of the housing 11, is summarized. The motor chamber 30 is located on the upper front side of the housing 11, the blower fan chamber 31 is located on the upper rear side, and electrostatically appears on the lower front side of the blower fan chamber 31 (the front side near the center of the housing 11). The atomization section storage chamber 34 is located, and the heating section storage chamber 33 is positioned on the rear side below the blower fan chamber 31 (the rear side closer to the upper center of the housing 11). The humidification part storage chamber 35 is located on the lower side (lower part of the casing 11). In FIG. 7, for convenience of explanation, the motor chamber 30, the blower fan chamber 31, the heating unit storage chamber 33, and the humidification unit storage chamber 35 are shown surrounded by a one-dot chain line, and the electrostatic atomization unit storage chamber 34 is surrounded by a broken line.

  Specific configurations of the heating unit 13, the opening / closing lid unit 14, the humidification unit 15, the electrostatic atomization unit 16, the first duct 18, and the second duct 20 are not particularly limited, and a known configuration is preferably used. it can. For example, the heating unit 13 may be of any type as long as it is a known heater known to be used in the field of electric heating, and the humidifying unit 15 humidifies the room. Any type of humidification mechanism known to be used in the field may be used.

  Moreover, the electrostatic atomizer 16 should just be what can produce | generate the said charged fine particle water from the water | moisture content contained in the air ventilated from the ventilation part 12. FIG. The specific configuration of the electrostatic atomizer 16 is not particularly limited.For example, a discharge electrode, a cooling member that cools the discharge electrode to condense water, a heat dissipation member that dissipates heat from the cooling member, and The structure which atomizes the water which condensed on the said discharge electrode by applying a voltage to the said discharge electrode can be mentioned. In general, “electrostatic atomization” means that the moisture contained in the air to be blown is condensed and voltage is applied, and by repeating Rayleigh splitting, for example, it has an average particle diameter in the range of 3 to 100 nm. The generation of charged fine particle water.

  Further, the specific configurations of the first duct 18 and the second duct 20 are not particularly limited, and are configured to be attached inside the casing 11 as independent air passage members (tube members) inside the casing 11. Alternatively, the first duct 18 and the second duct 20 may be integrated, and may be configured to be mounted in the housing 11, or various wall members provided in the housing 11, A configuration formed as a series of ducts by partition members, openings, or the like, that is, a configuration integrated in advance inside the housing 11 may be employed.

  However, in the present embodiment, at least a part of the second duct 20 needs to be located between the second air blowing port 19 and the electrostatic atomizer 16. In other words, the air flow that circulates via the electrostatic atomizer 16 may be configured so that the flow is directed by the second duct 20. Further, particularly preferably, the second duct 20 is configured such that the cross-sectional area from the upstream to the downstream in the air blowing direction gradually decreases in the vicinity of the second air blowing port 19 (that is, the rear end portion of the second duct 20). It only has to be done. This point will be described later.

[Operation of electric heater]
Next, an example of the operation of the electric heater 10 according to the present embodiment will be specifically described with reference to FIG. In the present embodiment, the electric heater 10 has a hot air blowing function, a humidifying function, an electrostatic atomizing function, etc., as exemplified in the description of the operation unit 26 (see FIG. 5). In the present embodiment, the state in which the hot air blowing function and the electrostatic atomization function are operated and the state in which the humidification function is further operated will be described separately.

  First, a state where the warm air blowing function and the electrostatic atomizing function are operated will be described. When the hot air blowing function and the electrostatic atomization function of the electric heater 10 are operated by operating the operation unit 26 (see FIG. 5), the blower fan 28 is also rotated by the rotation of the motor 27, thereby the blower fan chamber. A negative pressure is generated in 31. As the air blowing unit 12 operates in this way, external air is introduced into the housing 11 from the air suction port 32. Then, as indicated by an arrow As in FIG. 7, a main air flow (main wind) is directed from the upper blower fan chamber 31 toward the lower heating portion storage chamber 33 (inside the vertical portion of the first duct 18). Arise. The main wind As is heated by the heating unit 13, thereby forming “warm air”.

  At this time, since the opening / closing lid portion 14 is in a state in which the humidification path inlet 51 is closed, the first duct 18 is not in communication with the humidification portion storage chamber 35 as shown in FIG. Only for heating). Therefore, the warm air formed in the heating unit storage chamber 33 flows through the first duct 18, blows out from the first air outlet 17 as indicated by the arrow Aw, and warm air from the front (front) of the electric heater 10. Is released.

  In addition, as shown by an arrow Ab in FIG. 7, the air branched from the upper blower fan chamber 31 toward the lower front electrostatic atomizer housing chamber 34 (inside the vertical portion of the second duct 20). A flow (branch wind) is generated. A mist of charged fine particle water is added to the branched wind Ab by the electrostatic atomizer 16. As a result, “atomized wind” is formed. The atomized wind flows through the second duct 20 and is blown out from the second air outlet 19 as indicated by an arrow Am, and the atomized wind is released from the front (front) of the electric heater 10.

  In particular, in the present embodiment, since the electrostatic atomization portion storage chamber 34 is inside the vertical portion of the second duct 20, the branch air Ab blown from the blower portion 12 is It becomes easy to flow into the inside from the opening on the tip side. That is, the electrostatic atomization portion storage chamber 34 does not necessarily have to be provided as the inside of the second duct 20, but as shown in FIG. 7, by being provided inside the vertical portion of the second duct 20, The airflow blown from the blower 12 is guided from the opening at the tip of the second duct 20 to the electrostatic atomizer housing chamber 34, so that the branch air Ab is well formed. Therefore, the electrostatic atomization part 16 can prepare the atomization wind favorably.

  Here, as schematically shown in FIG. 7, the shape of the second duct 20 is such that its cross-sectional area gradually increases toward the second air outlet 19 in the vicinity of the end portion (lateral portion) of the second air outlet 19. It is configured in a shape that becomes narrower. In the present embodiment, for example, FIG. 7 schematically shows the upper edge (upper end) of the second air outlet 19 substantially overlapping with the upper edge of the air outlet opening 50, although it is schematically shown until the tiredness. The upper surface of the second duct 20 on the inner side when viewed from the second air outlet 19 is higher than the upper end of the outlet opening 50, and the lower surface is flat in the horizontal direction.

  If the 2nd duct 20 is comprised in this way, the flow rate of the atomization wind (arrow Am in the figure) which blows off from the 2nd ventilation opening 19 is relatively compared with the case where the 2nd duct 20 does not exist. growing. Here, the first air blowing port 17 is located immediately below the second air blowing port 19, and hot air (arrow Aw in the figure) blows out from here. Although this warm air has a larger flow rate than the atomized wind, the atomized wind having a relatively high speed is mixed with warm air having a large flow rate at a position immediately after the blowout (near the outlet opening 50). Matching is avoided. Therefore, the warm air and the atomized air are not mixed immediately on the front surface of the housing 11, but are merged at a position away from the entire surface by a predetermined dimension and mixed at the position.

  In addition, since the position where the warm air and the atomized wind merge is set in advance as a position where the user may directly receive the warm air blown from the electric heater 10, it is referred to as “heating position” for convenience. Called. Details of the heating position will be described later. Details regarding the confluence of warm air and atomized air will also be described later.

  Next, a state in which the humidification function is operated in addition to the warm air blowing function and the electrostatic atomization function will be described. When the hot air blowing function, the electrostatic atomization function, and the humidifying function of the electric heater 10 are operated by the operation of the operation unit 26, as described above, the blowing unit 12 causes the main wind indicated by the arrow As and the arrow Ab to The branch wind shown is produced. And the main wind As is heated by the heating part 13 and a warm air is formed, and the branched wind Ab is prepared as an atomization wind by the electrostatic atomization part 16. FIG.

  Here, if the humidification function is operated, the opening / closing lid portion 14 is switched from the closed state to the opened state of the humidification passage inlet 51, and therefore, as shown by a two-dot chain line in FIG. 7, The humidifying part storage chamber 35 is in a state of being communicated via the humidifying passage inlet 51 (a warming / humidifying combined use state). Therefore, the warm air formed in the heating unit storage chamber 33 flows into the humidification unit storage chamber 35 from the first duct 18. Then, as indicated by a two-dot chain line arrow Ah in the figure, the warm air is humidified by the humidifying unit 15 to become “humidified warm air”, and then flows into the first duct 18 through the first duct junction 52. Thereafter, as indicated by the arrow Aw, warm air blows out from the first air blowing port 17. In addition, as described above, the atomized air also blows out from the second air outlet 19, but the warm air and the atomized air are not mixed immediately at the front surface of the housing 11 and are merged at the heating position. Become.

[Merge of warm air and atomized air]
Next, in the present embodiment, the merging of the warm air blown from the first blower port 17 and the atomized wind blown from the second blower port 19 will be described together with a moistening effect on the user by the atomized air. To do.

  As described above, the electric heater 10 according to the present embodiment includes the electrostatic atomization unit 16 for electrostatic atomization of the air flow, thereby blowing out the atomized wind from the second air outlet 19. can do. This atomized wind can give the user an effect that should be called, for example, a “moisturizing skin effect”.

  Specifically, when the concentration of the charged fine particle water released into the air by electrostatic atomization is appropriate, it is possible to give a skin moisturizing effect to an indoor user. This moisturizing effect is different from the skin beautifying effect obtained by simply adjusting the humidity by humidification.

  That is, electrostatic atomization does not simply result in a high vapor pressure in the room, but includes charged water particles (charged fine particle water) having an average particle size of nanometer level at a certain concentration in the air. That is. For example, when the charged fine particle water comes into contact with sebum existing on the skin surface of the human body, the charged fine particle water affects the sebum and makes it easy to become familiar with moisture. Therefore, the hydrophobized sebum suppresses the amount of moisture transpiration from the skin, and as a result, the skin can be kept moist.

  In this way, by adding charged fine particle water to the warm air, it is possible to give a “moisturizing skin effect” different from the normal skin effect to the user. Even when warm air is not directly applied to the human body, if warm air containing charged fine particle water is generated for a long time, the room being heated can be filled with atomized air. Therefore, it is possible to perform sterilization or deodorization of the room with the charged fine particle water (sterilization and deodorization effect).

  However, when the atomized wind containing charged fine particle water is rapidly mixed with warm air in the vicinity of the outlet opening 50, the charged fine particle water is rapidly vaporized. It becomes difficult to obtain a “bacterial deodorizing effect”.

  For example, in the state where the second duct 20 in the present embodiment does not exist, the atomizing air prepared by the electrostatic atomizing unit 16 does not form a relatively high-speed atomizing air and the second air blowing port 19. Will blow out. In addition, warm air immediately after being heated by the heating unit 13 is blown out from the first blower port 17 located below the second blower port 19. For this reason, if the relatively high temperature hot air and the atomized air are in direct contact, a part of the charged fine particle water will be evaporated in the atomized air in contact. In addition, if the atomized air does not form a high-speed flow, it is easy to mix with hot air at a position immediately after the blowout (near the blowout opening 50). In this case, most of the charged fine particle water evaporates and disappears from the atomized air.

  Here, in a general electric heater, as a position where the user may directly receive the warm air from the electric heater, the air blowing surface of the electric heater (in the electric heater 10 according to the present embodiment) Can be assumed a position about 100 cm away from the front surface shown in FIG. That is, it is assumed that the user directly receives the warm air from the electric heater at a position about 100 cm away from the air blowing surface and obtains a feeling of warmth. Further, although depending on various conditions, for example, the temperature of the warm air immediately after blowing is about 100 ° C. (within a range of about 90 to 110 ° C.) as an example of the actually measured value, and the user is at a position of about 100 cm. When the hot air hits, when the temperature of the hot air of about 100 ° C. gradually decreases from the outer edge near the air outlet and reaches the position of about 100 cm, the total temperature of the hot air is about 30 ° C. (25-35 It has been experimentally confirmed that the temperature falls to within a range of about ° C.

  As described above, if the position where the user directly receives the warm air is defined as the “heating position”, the warm air and the atomized air may be combined in the vicinity of the heating position. As a result, it is possible to effectively avoid the disappearance of the charged fine particle water, so that warm air containing the charged fine particle water can be given to the indoor user.

  In the present embodiment, at least the second duct 20 is provided to join the warm air and the atomized air at the heating position. As for this 2nd duct 20, the opening area of the 2nd ventilation port 19 which is the downstream of atomization wind becomes the smallest in a rear-end part, and it sees from the 2nd ventilation port 19, and goes toward the upstream of atomization wind. The sectional area is gradually increased. In other words, the second duct 20 has a configuration in which the cross-sectional area gradually decreases toward the second air blowing port 19 at least at a site downstream in the air blowing direction from the electrostatic atomizing portion storage chamber 34. Yes. If it is this structure, in the horizontal site | part of the substantially L-shaped 2nd duct 20, the ventilation area becomes narrow toward the downstream from the upstream of a ventilation direction. Therefore, the atomizing wind formed through the electrostatic atomizing unit 16 can gradually increase the flow velocity in the process of flowing along the lateral portion of the second duct 20.

  The specific flow rate of the atomized wind is not particularly limited. For example, if the heating position is set to about 100 cm from the air blowing surface, the user will not feel a cool wind when directly hitting the atomized wind, and Any flow rate that does not easily mix with warm air may be used. As an example of the flow rate of the atomized wind, a range of 2 to 5 m / s can be mentioned.

  Here, in front of the air outlet opening 50, the flow path of the warm air and the flow path of the atomized air are separated by the first duct 18 and the second duct 20 inside the housing 11. There is no substitute for the flow paths being adjacent to each other. In this case, it can be said that the atomized wind is in direct contact with the relatively hot air. Therefore, as described above, there is an undeniable possibility that the heated air is affected by the atomizing air through the sectional surface.

  However, while the electric heater 10 is in operation, the air is always blown. Therefore, in the position where the first duct 18 and the second duct 20 are adjacent, neither heated air nor atomized air stays. In addition, warm air and atomized air are formed respectively. Therefore, it is considered that there is almost no thermal influence from high-temperature warmed air to atomized air.

  Moreover, the warm air and the atomized air that are adjacent to each other clearly differ in flow rate and flow velocity. First, in terms of the flow rate, for example, as shown in FIG. 1, the first air blowing port 17 that blows out warm air is larger than the second air blowing port 19 that blows atomized air. As an example, the ratio of the opening area of the second air outlet 19 to the first air outlet 17 can be about 0.04. And the shape of the 1st duct 18 and the 2nd duct 20 which connects these ventilation openings and the ventilation parts 12 also has a cross section corresponding to these ventilation openings. Here, in view of the role of each air flow, the atomized wind is an air flow for supplying charged fine particle water, and the warm air is an air flow for supplying an amount of heat for warming the room and the user. Therefore, since the warm air blown from the first blower port 17 through the first duct 18 (and the heating unit 13) from the blower unit 12 needs to have a large amount of heat for warming the room, a large flow rate is required. Air flow. On the other hand, the atomized wind blown from the second blower port 19 through the second duct 20 (and the electrostatic atomizing unit 16) from the blower unit 12 supplies charged fine particle water, and therefore has a small flow rate of air. The flow will be good.

  Further, regarding the flow velocity, as described above, the atomized wind that has passed through the second duct 20 does not significantly decrease the flow velocity at the time when the air is blown from the blower 12, and the flow velocity depends on the shape of the second duct 20. The air is blown out from the second air outlet 19 after being urged to rise. On the other hand, the warm air is blown out from the first air outlet 17 in a state where the flow velocity at the time when the air is blown from the blower 12 is generally maintained. Here, the airflow flowing into the second duct 20 is a branched wind indicated by an arrow Ab in FIG. 7, but the airflow flowing into the first duct 18 is a main wind indicated by an arrow As in FIG. The branch wind Ab and the main wind As are not at the same flow rate. However, when these air flows pass through the first duct 18 or the second duct 20, the flow rates differ from each other. Therefore, the flow rate of the atomized air and the flow rate of the warm air are different from each other. In addition, although the flow rate of warm air is not specifically limited, For example, the range of 15-30 m / s can be mentioned, Usually, it is faster than the flow rate of atomization wind.

  Thus, in this Embodiment, while the flow velocity of warm air and atomization wind differs, in addition to the flow volume of an air flow differing further, the 1st ventilation port 17 adjoins the 2nd ventilation port 19 below. Therefore, the atomized wind flows above the warm air. Accordingly, the warm air and the atomized air are avoided from being mixed in the vicinity of the outlet opening 50, and can be suitably merged in the vicinity of the heating position.

  When this point is demonstrated concretely, since the said warm air itself is high temperature, the warm air which blows off from the 1st ventilation port 17 will rise gradually as it leaves the housing | casing 11 immediately after blowing. On the other hand, the atomized wind from the second air blowing port 19 tends to go straight forward substantially in the state of being urged by the second duct 20. Here, from Bernoulli's theorem, the pressure of a relatively fast fluid is lower than the pressure of a relatively slow fluid. As described above, since the flow velocity of the warm air is usually faster than the flow velocity of the atomized air, the atomized air is attracted to the warm air when viewed from the atomized air.

  Further, since the atomized air is blown forward from the second blower opening 19 having a small opening area, in addition to being urged by the second duct 20 to increase the flow velocity, the forward flow is directed forward. High directivity (forward directivity). On the other hand, the warm air flows at a larger flow rate and gradually rises than the atomized wind, but since the forward directivity is smaller than that of the atomized wind, it tends to diffuse relatively easily.

  In addition, as described above, the temperature of the warm air is high immediately after being blown out from the first blower port 17, but the temperature starts to decrease immediately after being blown out. Therefore, the temperature of the warm air itself is sufficiently lowered until the warm air reaches the heating position assumed as the position of the user. Therefore, in the heating position, the temperature of the hot air is relaxed to a temperature at which the user feels warm and the water molecules do not rapidly vaporize.

  Therefore, for example, as shown in FIG. 8, “hot air with a large flow rate and high speed and low directivity” blows out from the first air blowing port 17 (arrow Aw1 in the figure) to form an “updraft”. Although it flows obliquely upward (arrow Aw2 in the figure), “low-flow, low-speed, high-directivity atomized wind” is not caught in hot air immediately after blowing (arrow Am in the figure), When it becomes an ascending air current, it is taken in so as to be caught in the hot air.

  In particular, since the atomizing wind with high forward directivity is formed well by the action of the second duct 20, as shown in FIG. 8, the charged fine particle water H0 (circle mark in the figure) contained in the atomizing wind 2 Immediately after blowing from the blower port 19, a part of the lower side indicated by a region Ev surrounded by a broken line in the figure is hot hot air Aw1 (indicated by a black arrow in the figure) or semi-hot hot air Aw2. Evaporated due to the influence of (indicated by hatching arrows in the figure) (charged fine particle water H1 during evaporation indicated by triangular marks in the figure) or disappeared completely (disappeared charge indicated by X marks in the figure) Although most of the particulate water H2), most of the middle to upper side is carried forward while maintaining a normal state. However, since the temperature of the hot air Aw1 decreases immediately after being blown out to become a semi-high temperature hot air Aw2, the disappearance or evaporation of the charged fine particle water H0 decreases as the warm air Aw2 advances forward, and further heating is performed. In the vicinity of reaching the position, the warm air Aw3 (indicated by a white arrow in the figure) is reduced in temperature, and the charged fine particle water H0 is mixed with the warm air Aw3.

  As described above, the atomized wind is effectively suppressed from being diffused immediately after being blown out until the atomized wind is taken into the warm air whose temperature has decreased in the vicinity of the heating position. Therefore, since the atomized air that forms the atomized air hardly mixes with the heated air that forms the warm air, the charged fine particle water contained in the atomized air hardly evaporates and is applied at a predetermined position. It will be mixed with warm air.

  That is, according to the present embodiment, these two air flows of warm air and atomized air can be suitably merged in the vicinity of a predetermined position (that is, the heating position). Therefore, the user can take the heating with the hot air having a suitable temperature, and even if the user receives the hot air directly, the moisture to the skin is satisfied by the charged fine particle water. It is possible to effectively suppress the uncomfortable feeling of drying caused by the above.

  In the present embodiment, either warm air that has only been heated or warm air that has been humidified can be selected and blown out from the first blower port 17. Therefore, if necessary, it is possible to provide heating that is comfortable for the user by switching between warm air that has only been heated and warm air that has been humidified. For example, if it is desired to improve the moisturizing effect, humidified warm air may be blown out. As a result, the humidity in the room can be maintained at a suitable level, and in addition to the moisturizing effect on the skin by the charged fine particle water, a moisturizing effect by appropriate humidity can be obtained.

  The heating position where the warm air and the atomized air are merged is not limited to a position of about 1 m from the front surface of the electric heater 10, and the usage environment or usage state of the electric heater 10, What is necessary is just to set beforehand according to various conditions, such as length, the ventilation speed by the ventilation part 12, and the positional relationship of the 1st ventilation port 17 and the 2nd ventilation port 19. FIG.

  Here, in the present embodiment, as shown in FIG. 1, FIG. 3, or FIG. 4, since the louvers 24a and 24b are provided in the outlet opening 50, the direction of the louvers 24a or louvers 24b is changed. Thus, it is possible to change the directions of the warm air and the atomized air to arbitrary directions. In this case, for example, when viewed from the front of the electric heater 10, these air flows can be merged before a predetermined heating position, or can be merged at a position farther than the predetermined heating position. That is, it is also possible to configure the heating position to be changed by using a wind direction adjusting member such as the louvers 24a and 24b.

  In this configuration, the louvers 24a and 24b change the angles of the louvers 24a and 24b mechanically or automatically (using a motor and a drive mechanism) in conjunction with the start of operation of the electrostatic atomization function. It may be configured to. Alternatively, the angle of the louvers 24a and 24b is automatically changed according to a specific heating position (predetermined distance from the front surface of the electric heater 10) by operating the operation unit 26, or manually changed by the user. Even in the case of performing, it may be configured to provide a scale or the like that can be used as a guide for change.

  Moreover, in this Embodiment, although the opening area of the 1st ventilation opening 17 is larger than the opening area of the 2nd ventilation opening 19, for example, the opening area of the 2nd ventilation opening 19 with respect to the opening area of the 1st ventilation opening 17 is sufficient. The ratio of the opening areas is not particularly limited. Similarly, in the present embodiment, the flow rate of the warm air blown from the first blower port 17 is larger than the flow rate of the atomized wind blown from the second blower port 19, but the flow rate of the warm air is There is no particular limitation on the ratio of the flow rate of the atomized air. Similarly, in the present embodiment, the flow rate of the atomized air blown from the second blower port 19 is higher than the flow rate of the warm air blown from the first blower port 17. There is no particular limitation on the flow rate ratio of the wind. Furthermore, the mixing ratio of the atomized air to the heated air is not particularly limited when the warm air and the atomized air are merged at the heating position.

  For the opening area ratio, the flow rate ratio, the flow rate ratio, or the mixing ratio, depending on the more specific configuration of the electric heater 10, the expected "moisturizing skin effect" or "sanitization and deodorization effect", etc. It is needless to say that an appropriate numerical range can be set as appropriate and is not limited to a specific numerical range.

[Modification]
In electric heater 10 according to the present embodiment, first air outlet 17 and second air outlet 19 are preferably disposed adjacent to each other. Thereby, as above-mentioned, the effect | action in which warm air and atomization wind attract each other can be improved. However, the 1st ventilation port 17 and the 2nd ventilation port 19 do not need to be arrange | positioned adjacently, if the warm air and the atomization wind can be made to merge at a predetermined heating position, for example, the front plate 21 You may arrange | position apart from up and down.

  In the present embodiment, the second duct 20 is indispensable for improving forward directivity and flow velocity in the atomized wind, but the first duct 18 is not necessarily provided. Also good. In the present embodiment, the second air blowing port 19 that is the rear end side opening of the second duct 20 is formed with a sufficiently small opening area as compared with the first air blowing port 17. Therefore, when the air flow supplied from the blower unit 12 is blown out as the atomized air from the second air blowing port 19, the atomized air blowing duct such as the second duct 20 is required.

  On the other hand, most of the air flow supplied from the air blowing unit 12 can be blown out from the first air blowing port 17 as it is through the heating unit 13. In this case, for example, a space that has a region (the heating portion storage chamber 33) in which the heating unit 13 is arranged and communicates from the blower unit 12 to the first blower port 17 is formed in the housing 11. If comprised in this way, it will become possible to comprise so that the main wind As from the ventilation part 12 may flow to the 1st ventilation port 17, even if it does not guide | lead with warm air ventilation ducts, such as the 1st duct 18.

  Of course, by providing the first duct 18, it is possible to clearly guide the blowing direction of the warm air toward the first blowing port 17, and the branch position (humidification route) to the humidification route (humidification portion storage chamber 35). The first duct 18 is preferably provided because of the advantages that the inlet 51) and the merging position (first duct merging port 52) can be appropriately positioned.

  Further, the first duct 18 may be configured to connect the heating unit 13 and the first blower port 17 instead of connecting the blower unit 12 and the first blower port 17. For example, in the present embodiment, the first duct 18 is configured to connect the first air blowing port 17 from below the blower fan chamber 31, and has a heating unit storage chamber 33 in the first duct 18. However, the blower fan chamber 31 and the heating unit storage chamber 33 are adjacent to each other due to the internal configuration of the housing 11, and the first duct 18 is supplied from the heating unit storage chamber 33 (that is, the heating unit 13). It may be configured to connect the mouth 17. That is, in the present embodiment, the specific configuration of the first duct 18 is not limited as long as the first duct 18 is a hot air blowing duct that blows warm air.

  Moreover, since the humidification part storage chamber 35 is configured to function as a bypass (humidification path) of the first duct 18 in the present embodiment, it may be provided at a position adjacent to the first duct 18. However, it is not necessary to be provided at a position adjacent to the lower side of the first duct 18 as shown in FIG. Further, if the warm air blown out by the electric heater 10 according to the present embodiment is configured to be always humidified, the humidifying portion storage chamber 35 is not provided as a bypass of the first duct 18. Instead, it may be provided inside the first duct 18 in the same manner as the heating part storage chamber 33.

  Moreover, in this Embodiment, although the electrostatic atomization part 16 is provided as a structure for preparing atomization air, this invention is not limited to this, As another structure for preparing atomization air, A configuration may be adopted. That is, the electric heater 10 according to the present embodiment includes an atomized air generating unit that prepares atomized air by adding charged fine particle water to the air blown toward the second air outlet 19. The atomized air generating unit is not limited to the electrostatic atomizing unit 16. For example, the configuration may be such that charged fine particle water is formed from the water tank 29 and the charged fine particle water is included in the air flow flowing through the second duct 20.

  Moreover, in this Embodiment, although the 1st duct 18 and the 2nd duct 20 are all connected to the single ventilation part 12, this invention is not limited to such a structure, The 1st duct 18 A configuration may be provided in which a “first air blowing unit” that blows an air flow only to the air and a “second air blowing unit” that blows an air flow only to the second duct 20 are provided independently.

  Further, as shown in FIG. 9, a rib member 53 (shown in black in FIG. 9) is provided at the boundary position between the first blower port 17 and the second blower port 19 and at the attachment position of the louver 24 a. May be. In FIG. 9, unlike FIG. 7, the louvers 24 a and 24 b are illustrated for convenience of explaining the positional relationship of the rib members 53.

  In the present embodiment, even if the louver 24a is provided, mixing of warm air and atomized air in the vicinity of the air outlet opening 50 is effectively suppressed, but by providing the rib member 53 in an auxiliary manner, The possibility of mixing can be more effectively suppressed. In particular, warm air blows out from the lower first air blowing port 17, but the warm air that forms the hot air is high temperature, and therefore, part of the hot air blown out from the first air blowing port 17. The turbulent flow tends to rise toward the second air outlet 19. Therefore, if the rib member 53 is provided at the boundary position of each air outlet, it is possible to avoid such an increase in turbulent flow.

  Furthermore, in the present embodiment, the flow velocity of the warm air is higher than the flow velocity of the atomized air, but the present invention is not limited to this, and may be the same speed. The flow rate of the atomized wind may be higher than the flow rate of the warm air. In particular, if the flow rates of warm air and atomized air are different, one air flow tends to be attracted to the other air flow. It becomes possible to make it merge suitably.

(Embodiment 2)
The electric heater 10 according to the first embodiment has a configuration in which the second air outlet 19 is provided adjacent to the upper side of the first air outlet 17, but the electric heater according to the present embodiment is also provided. Then, the second blower port 19 is provided on the side of the first blower port 17. An example of this configuration will be specifically described with reference to FIG.

  As schematically shown in FIG. 10, the electric heater 40 according to the present embodiment has, on the front surface (front surface), a heating portion on the right side in the central portion of the casing 11 in the vertical direction (vertical direction). 41 is disposed, and an electrostatic atomizing section 42 is disposed on the left side of the central portion of the casing 11. Moreover, the 1st ventilation port 17 is provided so that it may open below the heating part 41 (namely, the lower right upper side in the housing | casing 11), and the 2nd ventilation port 19 may be provided below the electrostatic atomization part 42 (namely, it is. It is provided so as to open at the upper left side of the lower part of the housing 11. A humidifying unit 15 is provided at the bottom of the housing 11. FIG. 10 schematically shows the interior of the electric heater 40 by cutting and representing a part of the front plate 21 attached to the front surface of the electric heater 40.

  Thus, although the 1st ventilation port 17 and the 2nd ventilation port 19 are arrange | positioned along with right and left, the louver 43 located in a perpendicular direction is provided between these ventilation ports. The louver 43 may be fixed to the casing 11 or may be attached to the casing 11 via a hinge member so that the direction of the louver 43 can be appropriately changed by the user. . If it is the latter structure, by changing the direction of the louver 43 as appropriate, for example, a position where the warm air from the first air outlet 17 and the atomized air from the second air outlet 19 are merged (near the heating position). Can be changed as appropriate. The direction change of the louver 43 may be automatically performed as in the case of the louvers 24a and 24b in the first embodiment, or may be manually performed by a user.

  In the electric heater 40 according to the present embodiment, the same effects as those of the electric heater 10 according to the first embodiment can be obtained. In particular, in the present embodiment, the heating unit 41 and the static electricity Since the electric atomization part 42 is arrange | positioned in the horizontal direction, it is possible to make the height of the electric heater 40 relatively small. Therefore, for example, in the interior, it can be suitably used when a low-type coordinate is used.

  In addition, since the other structure in the electric heater 40 is substantially the same as that of the electric heater 10 in the said Embodiment 1, specific description is abbreviate | omitted.

  Moreover, in this Embodiment, the heating part 41 and the electrostatic atomization part 42 are arrange | positioned changing height, without arrange | positioning side by side so that it may become the same height. In view of the electric heater 40 as a whole, it is preferable to make the respective components adjacent to each other as much as possible in order to reduce the overall size of the electric heater 40. However, the position of the heating unit 41 is the position of the electrostatic atomization unit 42. It is preferable that the position be on the downstream side in the blowing direction. Thereby, possibility that the electrostatic atomization part 42 will receive the thermal influence from the heating part 41 becomes low, and it can enable suitable electrostatic atomization. In this respect, the positional relationship between the heating unit 13 and the electrostatic atomization unit 16 in the first embodiment is the same.

(Embodiment 3)
The electric heater 40 according to the second embodiment has a configuration in which the heating unit 41 and the electrostatic atomization unit 42 are arranged along the left and right sides in the horizontal direction, but the electric heating according to the present embodiment. In the machine, the heating unit 13 and the electrostatic atomizing unit 16 are arranged along the front and rear sides in the horizontal direction. An example of this configuration will be specifically described with reference to FIG.

  As schematically shown in FIG. 11, the electric heater 60 according to the present embodiment is the same as the electric heater 10 according to the first embodiment with respect to the basic configuration, but the vertical direction of the casing 11. The electrostatic atomization part 16 is located in the front side of the center part of a direction (vertical direction), and the heating part 13 is located in the back side. In this configuration, the first duct 61 has a substantially L-shaped vertical portion shorter than that of the first duct 18 in the first embodiment, while the second duct 62 has the shape described in the above embodiment. Unlike the second duct 20 in the first embodiment, the second duct 20 has a substantially linear shape that is inclined from the rear side to the front side of the housing 11.

  In particular, in the second duct 62, the specific configuration of the front end (front end of the casing 11) and the rear end (rear end of the casing 11) is different from that of the second duct 20. . First, the tip of the second duct 62, that is, the end on the second air outlet 19 side, the opening area on the second air outlet 19 side is narrowed down, and the electrostatic atomizer that houses the electrostatic atomizer 16. The blower nozzle 63 has a shape in which the cross-sectional area gradually increases toward the storage chamber 36.

  In the present embodiment, the tip of the second duct 62 does not have to be configured as the blower nozzle 63, but having the blower nozzle 63 is particularly preferable because the flow velocity of the atomized wind can be increased. . That is, in the first embodiment, since the second duct 20 is substantially L-shaped, the vertical portion has a role of providing the electrostatic atomizing portion storage chamber 34 therein, and the horizontal portion gradually increases. Since the cross-sectional area is narrowed, the atomizing wind is urged and forward directivity is provided. On the other hand, in the present embodiment, the second duct 62 is substantially linear, and the electrostatic atomizing portion storage chamber 36 is provided in the main body thereof. The structure is such that the roles cannot be divided. Therefore, by setting the tip connected to the second blower port 19 as the blower nozzle 63, it is possible to impart urging and forward directivity to the atomized wind.

  Further, a wind receiving portion 64 for guiding the branched air Ab is provided at the rear end of the second duct 62, that is, the opening on the side where the branched air Ab is introduced from the blower 12. In the present embodiment, although schematically shown in FIG. 11, the wind receiving portion 64 extends from the rear end of the second duct 62 toward the inside of the first duct 61 (the rear side of the housing 11). The first duct 61 has a shape extending upward along the vertical portion (vertical direction of the casing 11). The schematic shape shown in FIG. 11 is substantially L-shaped.

  The vertical portion of the heating unit 13 and the first duct 61 is located immediately below the blower fan 28 in the blower unit 12, but the second duct 62 is not located directly below the blower fan 28 but below the motor 27. To do. Therefore, the rear end of the second duct 62 extends toward the inside of the first duct 61 in order to guide the branch air Ab to the second duct 62. Further, the air flow (main wind As) blown from the blower fan 28 is in a direction from the upper part to the lower part of the housing 11. Therefore, in order to guide the branch air Ab from the main wind As, the rear end of the second duct 62 is bent and extended so as to stand upward along the air blowing direction of the main wind As. As described above, if the rear end of the second duct 62 is a bent wind receiving portion 64, the branched air Ab can be easily formed from the main wind As.

  In the electric heater 60 having the above-described configuration, the same effects as the electric heater 10 according to the first embodiment and the electric heater 40 according to the second embodiment can be obtained. In the embodiment, the configuration of the first duct 61 and the second duct 62 is devised and the heating unit 41 and the electrostatic atomization unit 42 are arranged in the front-rear direction, so the height of the electric heater 60 is relatively It is possible to make it smaller. Further, unlike the electric heater 40 according to the second embodiment, the shape, size, arrangement, and the like of the first air outlet 17 and the second air outlet 19 are the same as those of the electric heater 10 according to the first embodiment. It can be configured.

  In addition, since the other structure in the electric heater 60 is substantially the same as the structure of the electric heater 10 in the said Embodiment 1, concrete description is abbreviate | omitted.

  Moreover, in this Embodiment, the heating part 13 and the electrostatic atomization part 16 are arrange | positioned along with it so that it may become the same height before and behind the housing | casing 11. FIG. As described in the second embodiment, in order to make the electrostatic atomization unit 16 less susceptible to thermal influence from the heating unit 13, it is better to separate the heating unit 13 from the electrostatic atomization unit 16. However, in the present embodiment, the configuration of the first duct 61 and the second duct 62 is devised to allow the second duct 62 to be heated from the heating unit 13 in the first duct 61 (in the heating unit storage chamber 33). The thermal influence on the electrostatic atomizer 16 in the inside (in the electrostatic atomizer storage chamber 36) can be greatly reduced. For example, the structure which makes the material of the 1st duct 61 and the 2nd duct 62 high heat insulation, or makes a heat insulating material pinch | interpose between the 1st duct 61 and the 2nd duct 62 is mentioned. Thereby, while being able to perform suitable electrostatic atomization in the electrostatic atomization part 16, the electric heater 60 can be reduced more in size.

  As described above, the electric heater according to the present invention includes a housing, a blower that sucks outside air from the outside of the housing and blows the air to the other, and blows air sent from the blower from the first blower opening. A first duct for air flow, a second duct for blowing air sent from the blower section from the second blower port, and air sent from the blower section in the first duct to a predetermined temperature. A warming section that warms (warms) the heated air; an electrostatic atomizing section that creates atomized air by adding charged fine particles to the air sent from the blower section in the second duct; The heated air blown from the first blower port and the atomized air blown from the second blower port merge at a position away from the housing by a predetermined dimension. Any configuration in which the direction is controlled may be used.

  In the present invention, the first air outlet and the second air outlet are provided independently so that the air blowing directions are controlled. Therefore, the heated air blown from the first blower port and the atomized air blown from the second blower port merge at a position away from the casing by a predetermined dimension. As a result, the temperature of the heated air, which was high at the first air outlet, is lowered to some extent at a position away from the predetermined dimension, and the charged fine particle water is not destroyed by heat. And since charged fine particle water can be made to reach a user in a room enough, while being able to adjust heating temperature to desired temperature, moisture can be given to human skin.

  In the electric heater according to the present invention, it is preferable that an opening area of the first air outlet is larger than an opening area of the second air outlet. Thereby, the ratio of warm air and atomization air can be set to the optimal mixing ratio, and they can be merged at a position away from the casing by a predetermined dimension.

  In the electric heater according to the present invention, it is preferable that the flow rate of the atomized air blown from the second blower port is faster than the flow rate of the heated air blown from the first blower port. As a result, the air can be blown to a position away from the casing by a predetermined dimension without being mixed immediately after being blown out from the respective air outlets, and then merged.

  In the electric heater according to the present invention, it is preferable that the first air outlet is provided below the housing and the second air outlet is provided above the housing. Thereby, it is possible to raise the warmed air blown from the first blower opening as it is away from the housing and efficiently join the atomized air blown from the second blower opening.

  The electric heater according to the present invention has the electrostatic atomization unit, condenses moisture contained in the air sent from the blower unit, applies a voltage, and repeats Rayleigh splitting to about 3 to 100 nm. It is preferable to produce charged fine particle water. As a result, when nanometer-size (name level) charged fine particle water generated by the electrostatic atomizer and released into the air comes into contact with the sebum on the human skin surface, the sebum is denatured and is easily adapted to moisture. Therefore, the hydrophobized sebum can suppress moisture transpiration from the skin and keep the skin moist.

  It should be noted that the present invention is not limited to the description of the above-described embodiment, and various modifications are possible within the scope shown in the claims, and are disclosed in different embodiments and a plurality of modifications, respectively. Embodiments obtained by appropriately combining technical means are also included in the technical scope of the present invention.

  As described above, according to the present invention, since the merging and mixing of the warm air and the atomized air are optimally performed, it becomes possible to perform heating without impairing the advantages of the atomized air. The present invention can be widely applied not only to the field of electric heaters equipped with, but also to the field of various air conditioners.
