Description

  The present invention relates to an air conditioner that harmonizes indoor air.

  Patent Documents 1 and 2 disclose conventional air conditioners that take in indoor air to harmonize and send out conditioned air from a blowout port. The air conditioner disclosed in Patent Document 1 is provided with infrared sensors in a plurality of indoor areas, and the temperature of each area is detected by the infrared sensor. And the direction of the blowing airflow is changed based on the detected temperature to eliminate the temperature difference between the regions. Moreover, the air conditioner disclosed by patent document 2 can make indoor temperature uniform by sending conditioned air upward from a blower outlet.

  On the other hand, Patent Literature 3 discloses an air conditioner that intensively air-conditions two locations apart from each other in a room. In this air conditioner, for example, conditioned air is sent to the left from the upper part of the outlet, and conditioned air is sent to the right from the lower part. Moreover, it has the 1st, 2nd heat exchanger arrange | positioned in series, and the 1st, 2nd path | route which connects a 1st, 2nd heat exchanger is branched and provided. An opening / closing valve is provided in the first path, and an expansion valve and a capillary tube are provided in the second path.

  When the on-off valve is opened and the expansion valve is closed, the first and second heat exchangers have the same cooling capacity. When the on-off valve is closed and the expansion valve is opened, the refrigerant flowing through the refrigeration cycle flows into the second heat exchanger via the capillary tube, so that the cooling capacity of the second heat exchanger is higher than that of the first heat exchanger. . Thereby, the temperature sent from the upper part of the blower outlet through which a large amount of air passing through the first heat exchanger circulates is slightly higher in temperature than the air sent from the lower part of the blower outlet. For this reason, the space of the upper left part of an air conditioner can be made into high temperature, and the space of the lower right part can be made into low temperature.

  According to the air conditioner disclosed in Patent Documents 1 and 2, the temperature in the room is substantially uniform. For this reason, when there are a plurality of users in the room, there is a problem that the comfort cannot be satisfied for each user if the temperature at which each user feels comfortable is different. Moreover, even if the indoor temperature distribution is in a non-uniform state as described in the conventional example of Patent Document 2, it cannot be matched with the temperature at which each user feels comfortable.

  On the other hand, according to the air conditioner disclosed in Patent Document 3, the temperature difference between the first and second heat exchangers is formed depending on whether or not the refrigerant flowing through the refrigeration cycle passes through the capillary tube. For this reason, the temperature difference between the two spaces that are intensively air-conditioned is substantially constant. As a result, when the blowout temperature is controlled so that the user in one space feels comfortable, the temperature in the other space is determined in conjunction. Therefore, there may be a case where the temperature is not comfortable for the user in the other space, and there is a problem that the comfort cannot be satisfied for each user.

  An object of the present invention is to provide an air conditioner that can satisfy comfort for a plurality of users in a room.

  In order to achieve the above object, the present invention is provided with a wind direction plate that is rotatably supported at both ends in the longitudinal direction and changes the wind direction of the air outlet by turning, and air that has been taken in from the room and harmonized is emitted from the air outlet. In the air conditioner to be sent out indoors, the wind direction plate is composed of a twistable member that can be twisted by arranging both ends at different rotational positions, and the twistable member is composed of a flexible member and has both longitudinal ends. The portion has a torsional rigidity larger than that of the central portion, and further has a bone portion made of a hard material in which a plurality of openings are formed, and the bone portion has an opening area at both end portions smaller than that of the central portion. And

  In the air conditioner having the above-described configuration, the present invention is characterized in that the surface of the bone part is covered with a soft material. According to this configuration, the bone portion is covered with the soft material and the opening is closed.

  The present invention also includes an air conditioning plate that is rotatably supported at both ends in the longitudinal direction and changes the wind direction of the air outlet by turning, and air that is conditioned and taken in from the room is sent out from the air outlet to the room. In the machine, the wind direction plate is composed of a twistable member that can be twisted by disposing both ends at different rotational positions, and the twistable member is composed of a plurality of members joined together by an elastic body in the longitudinal direction. It is said. According to this configuration, the plurality of members are connected with the elastic material sandwiched therebetween, so that the twistable member is formed. When both ends of the twistable member are rotated at different angles, the direction of each member gradually changes via the elastic material.

  According to the present invention, in the air conditioner having the above-described configuration, a first drive motor connected to one end in the longitudinal direction of the twistable member, and a second drive connected to the other end and driven independently of the first drive motor. And a drive motor. According to this configuration, when both ends of the twistable member are rotated at different angles in the same rotational direction by the first and second drive motors, the twistable member is twisted. Further, both ends of the twistable member may be rotated in different rotation directions by the first and second drive motors.

  In the air conditioner having the above-described configuration, the present invention is characterized in that holding means for holding the twisted state of the twistable member is provided. According to this configuration, the holding means is formed of, for example, a worm gear, and is held by the holding member even when trying to return from the state twisted by the elastic force of the twistable member.

  In the air conditioner having the above-described configuration, the present invention is characterized in that air is sent in different directions from one side and the other side of the air outlet by twisting the wind direction plate. According to this configuration, the wind direction plate is twisted by rotating both ends.

  In the air conditioner having the above-described configuration, the first air stream blown from one side of the air outlet is blown downward or horizontally to circulate along the side wall of the room, and from the other side of the air outlet. The second air stream to be blown out is blown upward in the front and is circulated along the ceiling wall of the room.

  According to the present invention, since the wind direction plate is formed of a twistable member that can be twisted, air can be easily sent out from one and the other of the outlets in different directions. Thereby, the area | region which divided | segmented the room | chamber interior can be made into desired different temperature. Therefore, even when the temperature at which a plurality of users feel comfortable differs, the comfort of each user can be satisfied. Moreover, since the center in the longitudinal direction of the wind direction plate is not divided, it is possible to prevent the aesthetics from being impaired and to prevent dew condensation due to the turbulence of the airflow in the divided portions.

  Further, according to the present invention, since the twistable member is made of a flexible member, a wind direction plate that can be twisted can be easily realized.

  Further, according to the present invention, since both end portions in the longitudinal direction have higher torsional rigidity than the central portion, it is possible to prevent the end portions of the wind direction plate from being twisted by the rotation of both ends. Therefore, air can be reliably sent from the blower outlet in a desired direction.

  Further, according to the present invention, the twistable member has a bone portion made of a hard material whose opening area at both end portions is smaller than that at the central portion, so that a twistable member having both ends having greater torsional rigidity than the central portion can be easily formed. be able to. Moreover, since it does not deform | transform easily in a longitudinal direction, it can prevent that a wind direction board bends and it becomes impossible to block an outlet, for example. Furthermore, it is possible to suppress a decrease in formability caused by forming the twistable member into a plate shape with a single soft resin or the like, and to prevent sink marks and warpage.

  Further, according to the present invention, since the surface of the bone portion is covered with the soft material and the opening is closed, the state where the torsional rigidity at both ends is high and the torsional rigidity at the center is low can be easily maintained.

  Further, according to the present invention, since the twistable member is composed of a plurality of members joined in the longitudinal direction with an elastic material, a wind direction plate that can be twisted can be easily realized.

  According to the present invention, since the first and second motors that are driven independently are connected to both ends of the twistable member, the wind direction plate can be easily twisted.

  Further, according to the present invention, since the holding means for holding the twisted state of the twistable member is provided, it is possible to prevent the twisted state from being released by the elastic force of the twistable member.

  Further, according to the present invention, air is sent in different directions from one side and the other side of the air outlet by twisting the wind direction plate, so that airflow can be circulated in different directions on the one side and the other side of the room.

  Moreover, according to this invention, while blowing the 1st airflow which blows off from the one side of a blower outlet below or a horizontal direction and distribute | circulates along the side wall of a room, the 2nd airflow which blows off from the other side of a blower outlet is on front upper direction. Since it blows out and distribute | circulates along an indoor ceiling wall, a temperature difference can be easily provided in the 1st, 2nd area | region which divided the room | chamber interior into right and left. Therefore, even when the temperature at which a plurality of users feel comfortable differs, the comfort of each user can be satisfied.

<< First Embodiment >>
Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an indoor unit 1 of an air conditioner according to the first embodiment. The indoor unit 1 of the air conditioner has a main body held by a cabinet 2, and a front panel 3 provided with suction ports 4 on the upper surface side and the front surface side is detachably attached to the cabinet 2. The cabinet 2 is provided with a claw portion (not shown) on the rear side surface, and is supported by engaging the claw portion with a mounting plate (not shown) attached to the indoor side wall W1 (see FIG. 2).

  A blower outlet 5 for sending out air is provided at the front lower portion of the front panel 3. The blower outlet 5 is formed in the rectangle extended in the horizontal direction. The blower outlet 5 is provided with horizontal louvers 113a and 113b arranged side by side in the vertical direction. The lateral louver 113a is arranged at a position that closes the upper part of the air outlet 5. The lateral louver 113b is arranged at a position that closes the lower part of the air outlet 5.

  FIG. 2 is a side sectional view of the indoor unit 1. Inside the indoor unit 1, a blower path 6 that communicates from the suction port 4 to the blowout port 5 is formed. A blower fan 7 that sends out air is disposed in the blower path 6. For example, a cross flow fan or the like can be used as the blower fan 7. The blower path 6 is inclined downward as it goes forward, and has a front guide portion 6a that guides the air sent out by the blower fan 7 forward and downward. Moreover, the upper wall of the ventilation path 6 is an inclined surface that is inclined upward as it goes forward from the end of the front guide portion 6a.

The front guide portion 6a is provided with a plurality of vertical louvers 12a (see FIG. 3) and 12b. FIG. 3 shows a top view of the vertical louvers 12a and 12b. A plurality of vertical louvers 12a (first left and right wind direction changing portions) arranged on the left side are each pivotally supported at a central portion by a support shaft 12d substantially perpendicular to the bottom surface of the front guide portion 6a, and a rear portion is connected by a connecting member 12c. Yes. As a result, the plurality of vertical louvers 12a rotate in conjunction with each other, and change the airflow direction in the left-right direction of the airflow sent from the left outlet 5a (see FIG. 1) on the left side of the outlet 5.

  Similarly, a plurality of vertical louvers 12b (second left and right wind direction changing portions) arranged on the right side are each pivotally supported by a central shaft 12f that is substantially perpendicular to the front guide portion 6a, and a rear portion is coupled by a coupling member 12e. ing. As a result, the plurality of vertical louvers 12b rotate in conjunction with each other and change the airflow direction in the left-right direction of the airflow sent from the right-side outlet 5b (see FIG. 1) on the right side of the outlet 5.

  In FIG. 2, an air filter 8 that collects and removes dust contained in the air sucked from the suction port 4 is provided at a position facing the front panel 3. An indoor heat exchanger 9 is disposed between the blower fan 7 and the air filter 8 in the blower path 6. The indoor heat exchanger 9 is connected to a compressor (not shown) provided in an outdoor unit arranged outdoors, and the refrigeration cycle is operated by driving the compressor.

  The indoor heat exchanger 9 is cooled to a temperature lower than the ambient temperature during the cooling operation by the operation of the refrigeration cycle. Further, during the heating operation, the indoor heat exchanger 9 is heated to a temperature higher than the ambient temperature. A temperature sensor 61 is provided between the indoor heat exchanger 9 and the air filter 8 to detect the temperature of air sucked from the suction port 4, and the air conditioner is driven on the side of the indoor unit 1. A control unit (not shown) for controlling is provided. A drain pan 10 that collects condensation that has fallen from the indoor heat exchanger 9 during cooling or dehumidification is provided in the lower part before and after the indoor heat exchanger 9.

  4 and 5 are a side view and a top view showing a driving mechanism of the horizontal louver 113a. The horizontal louver 113a has horizontal rotation shafts 114 at both left and right ends, and a gear 77 is provided on the rotation shaft 114. The gear 77 meshes with a gear 76 provided on the shaft of the drive motor 75. The drive motors 75 are provided on the left and right sides of the lateral louver 113a and are driven independently. Accordingly, the horizontal louver 113a is rotated by driving the left and right drive motors 75 (first and second drive motors). The horizontal louver 113b is similarly driven by the left and right drive motors.

  FIG. 6 shows a plan view of the horizontal louver 113a. The horizontal louver 113a is formed in a rectangular plate shape in plan view by covering the surface of the bone portion 21 made of a hard resin molded product with a meat portion 22 made of a soft resin material. Thereby, the horizontal louver 113a has flexibility. FIG. 7 is a plan view showing the bone part 21. The bone portion 21 has a shape in which a plurality of openings 21c are provided in a central portion 21a to form a thin columnar portion 21d, and left and right end portions 21b are connected by the columnar portion 21d. For this reason, the central portion 21a has a low torsional rigidity, and both end portions 21b have a high torsional rigidity.

  8 and 9 are perspective views showing cross sections cut along lines AA and BB in FIG. The meat portion 22 is formed by covering the columnar portion 21d and the end portion 21b with a soft material and filling the opening 21c with the soft material. Therefore, the opening 21c is closed by the meat part 22, and the meat part 22 is made of a soft material, so that the torsional rigidity of the central part 21a is small and the torsional rigidity of both end parts 21b is maintained. Thereby, the horizontal louver 113a is a twistable member that can be twisted at the central portion 21a.

  When the shafts of the left and right drive motors 75 are rotated at different rotation angles from the state where the horizontal louver 113a is flat, both end portions 21b are arranged at different rotation positions. As a result, as shown in FIG. 10, the horizontal louver 113a is twisted, and the left portion of the horizontal louver 113a changes the vertical direction of the airflow sent from the left outlet 5a. The right portion of the horizontal louver 113a varies the vertical direction of the airflow sent from the right outlet 5b. The horizontal louver 113b is similarly configured. Further, when the lateral louvers 113a and 113b are twisted, the shafts of the left and right drive motors 75 may be rotated in the same direction at different rotation angles or in different directions.

  Since the torsional rigidity of both end portions 21b of the horizontal louvers 113a and 113b is smaller than that of the central portion 21a, it is possible to prevent only the both end portions 21b from being twisted by the rotation of the rotating shafts 114 at both ends. Therefore, air can be reliably sent in a desired direction from the left outlet 5a and the right outlet 5b. In this embodiment, although the opening 21c is provided in the center part 21a, you may provide an opening in the edge part 21b. At this time, the torsional rigidity of both end portions 21b can be made larger than that of the central portion 21a by making the opening area of the central portion 21a larger than that of the both end portions 21b.

  Further, since the bone portion 21 made of a hard material is provided, the lateral louvers 113a and 113b are not easily deformed in the longitudinal direction. Therefore, for example, it is possible to prevent the lateral louvers 113a and 113b from being bent so that the air outlet 5 cannot be blocked. Furthermore, it is possible to suppress the deterioration of moldability caused by molding the lateral louvers 113a and 113b into a plate shape with a single soft resin or the like, and to prevent sink marks and warpage.

  The torsional rigidity of the central portion 21a and the end portion 21b of the lateral louvers 113a and 113b can be changed to a desired size by the opening area of the opening 21c. Further, the twisting position and twisting width in the longitudinal direction of the horizontal louvers 113a and 113b can be varied to a desired setting by adjusting the ratio of the lengths of the central portion 21a and the end portion 21b. For example, as shown in FIG. 11, if the longitudinal direction of the opening 21c is shortened to reduce the opening area, the torsional rigidity of the central portion 21a increases, and the twisted portions are concentrated near the central portions of the lateral louvers 113a and 113b.

  For this reason, the horizontal louvers 113a and 113b are largely twisted at the center, and both ends are not so twisted. Thereby, when the horizontal louvers 113a and 113b are twisted, the upper and lower blowing directions of the airflow are rapidly changed between the left outlet 5a and the right outlet 5b. As a result, an air flow is sent out from the left outlet 5a in substantially the same direction, and an air stream is sent out from the right outlet 5b in substantially the same direction.

  Also, as shown in FIG. 12, when the longitudinal direction of the opening 21c is extended to increase the opening area, the torsional rigidity of the central portion 21a decreases, and the twisted portion extends from the center of the lateral louvers 113a and 113b to the vicinity of the end portion. It reaches. For this reason, the horizontal louvers 113a and 113b are gradually twisted in the longitudinal direction. Thereby, when the horizontal louvers 113a and 113b are twisted, the upper and lower blowing directions of the airflow continuously and gradually change in the longitudinal direction of the outlet 5.

  Further, a plurality of portions having openings and portions having no openings may be provided in the bone portion 21 in succession. For example, when a portion having no opening 21c is provided at both end portions and the central portion, and a portion having the opening 21c is provided therebetween, the lateral louvers 113a and 113b are provided between the left end portion and the central portion and between the central portion and the right end portion. Twists at two locations, and the left end, center, and right end are not twisted much. Thereby, when the horizontal louvers 113a and 113b are twisted, the upward and downward blowing directions of the airflow change rapidly between the left side and the center of the outlet 5, and change rapidly between the center and the right side. As a result, air currents are sent in substantially the same direction from the left side, the center, and the right side of the outlet 5.

  As described above, the upward and downward blowing directions of the airflow when the lateral louvers 113 a and 113 b are twisted can be set to a desired direction depending on the configuration of the bone portion 21. If the opening 21c is not provided in the central portion 21a of the bone portion 21 and the openings 21c are provided in the both end portions 21b, the lateral louvers 113a and 113b are hardly twisted at the center and are greatly twisted at both ends.

  Further, the shape of the opening 21c is not limited to a rectangular shape in plan view extending to both end portions 21b as shown in FIG. 7 described above, and various shapes can be used. For example, as shown in FIG. 13, it may be an opening 21c having a rectangular shape in plan view arranged side by side on the left and right. As shown in FIG. 14, it may be an opening 21c having a rectangular shape in plan view arranged side by side vertically and horizontally. As illustrated in FIG. 15, the opening 21 c may be a triangular triangle in plan view arranged side by side. As shown in FIG. 16, you may arrange the opening 21c which open | released the end in parallel up and down and right and left.

  In addition, the horizontal louvers 113a and 113b made of a twistable member may be formed by connecting a plurality of members made of a hard resin molded product or the like in the longitudinal direction via an elastic body such as rubber. Accordingly, when the left and right ends of the horizontal louvers 113a and 113b are arranged at different rotational positions, the elastic bodies are twisted so that the right and left sides of the horizontal louvers 113a and 113b can be arranged in different directions.

  When the louvers 113a and 113b are twisted, a force that returns to the original by an elastic force acts. For this reason, as shown in FIG. 17, a lever 78 for locking the gears 76 and 77 is provided. The lever 78 has a gear portion 78b that engages with the gears 76 and 77, and rotates around the rotation shaft 78a when the lateral louvers 113a and 113b are twisted.

  As a result, as shown in FIG. 18, the gear portion 78b meshes with the gears 76 and 77 to stop the rotation of the gears 76 and 77, thereby preventing the lateral louvers 113a and 113b from returning to the original state due to the elastic force. Accordingly, the lever 78 constitutes a holding means for holding the lateral louvers 113a and 113b in a twisted state.

  The holding means may have other configurations. For example, in FIG. 19, a holding means including a slide member 79 that slides is provided. The slide member 79 has gear portions 79a and 79b. The gear portion 79a meshes with the gear 80, and the slide member 79 slides up and down in the drawing as the gear 80 rotates. The gear portion 78 b is engaged with the gears 76 and 77 by sliding of the slide member 79.

  Therefore, as shown in FIG. 20, when the horizontal louvers 113a and 113b are twisted, the slide member 79 slides. The gear portion 79b meshes with the gears 76 and 77 to lock the rotation of the gears 76 and 77, thereby preventing the lateral louvers 113a and 113b from returning to the original state due to the elastic force.

  Further, as shown in the side view and plan view of FIGS. 21 and 22, a holding means including a worm gear 81 may be provided. A worm gear 81 that meshes with the gear 77 is provided on the shaft of the motor 75 in place of the gear 76 shown in FIGS. Thereby, the shaft of the motor 75 and the rotational axis of the lateral louver 113a are orthogonal to each other, and the gear 77 is locked to the worm gear 81 when the lateral louvers 113a and 113b are twisted. Therefore, the horizontal louvers 113a and 113b are prevented from returning to the original due to the elastic force.

  FIG. 23 is an external view showing a remote controller 31 for controlling the operation of the air conditioner of the present embodiment. The remote controller 31 has an operation unit 31a, a display unit 31b, and a transmission unit 31c. The operation unit 31a has a plurality of operation keys, and inputs an operation state of the air conditioner.

  The operation key of the operation unit 31a can be switched to an indoor cooling operation, a dehumidifying operation, or a heating operation. When the lower cover 31d is opened, another operation key is exposed, and the set temperature, wind direction, and wind speed can be set. In addition, the first and second regions obtained by dividing the room into left and right, front and rear, and top and bottom can be set separately.

  The display unit 31b includes a liquid crystal display panel or the like, and displays the operating condition, time, set temperature, and the like of the air conditioner. Further, the schematic shape of the room R in which the indoor unit 1 is installed and the schematic installation position of the indoor unit 1 are schematically displayed in a perspective view. For example, the set temperatures of the first and second regions divided into the left and right, front and rear, or top and bottom toward the indoor unit 1 can be set separately by visually recognizing the display unit 31b. In addition, the transmission unit 31 c transmits an operation signal from the operation unit 31 a to the indoor unit 1.

  Further, the user can set the wind speed to “light wind”, “weak wind”, “strong wind”, “automatic”, or the like. Thereby, it can be manually changed to a light breeze (about 4 m / s for a 6 tatami type air conditioner), a weak breeze (about 6 m / s), a strong breeze (about 8 m / s). In addition, when “automatic” is set, it can be switched to a light breeze, a light breeze, a strong breeze, etc. according to the driving situation.

  In the air conditioner having the above configuration, when a compressor (not shown) is driven, refrigerant from the outdoor unit (not shown) flows to the indoor heat exchanger 9 to operate the refrigeration cycle. Indoor air is sucked into the indoor unit 1 from the suction port 4 by driving the blower fan 7, and dust contained in the air is removed by the air filter 8.

  During the cooling operation, the air taken into the indoor unit 1 is cooled by exchanging heat with the indoor heat exchanger 9 on the low temperature side. The conditioned air cooled by the indoor heat exchanger 9 is sent out indoors with its direction regulated in the left-right direction and the up-down direction by the vertical louvers 12a, 12b and the horizontal louvers 113a, 113b.

<First air flow control>
In order to make the temperature distribution in the room uniform, the first airflow control is performed. As shown in FIG. 24, the upper lateral louver 113a is disposed at an angle of 20 ° with respect to the horizontal, for example, so that the front is upward. The lower horizontal louver 113b is disposed at an angle of, for example, 5 ° or less with respect to the horizontal between an obliquely lower side and a substantially horizontal side where the front is slightly lower. Further, the vertical louvers 12a and 12b are arranged facing the front as shown in FIG. The vertical louvers 12a and 12b may be inclined in a range up to about 5 ° with the front facing outward. Then, the wind speed is set to “light wind”, and conditioned air is sent out from the outlet 5.

  The air that flows through the blowing path 6 and is sent out from the upper part of the outlet 5 is guided obliquely upward along the lateral louver 113a. The air that flows through the blowing path 6 and is delivered from the lower part of the outlet 5 is guided slightly downward or substantially horizontally along the lateral louver 113b. At this time, the air that swirls clockwise in the drawing by the blower fan 7 in the drawing and circulates increases the air volume at the upper part of the blower path 6 on the inner peripheral side. For this reason, the air sent out from the lower part of the blower outlet 5 follows the air sent out from the upper part. As a result, the conditioned air is sent obliquely upward as indicated by an arrow B from the air outlet 5.

  Although the lower lateral louver 113b may be arranged so as to go upward as it goes forward, the air may be guided upward, but the conditioned air flowing along the lower surface of the lateral louver 113b decreases. For this reason, there is a case where condensation occurs due to a temperature difference between the upper surface and the lower surface of the horizontal louver 113b. Therefore, it is more desirable to arrange the horizontal louver 113b between obliquely below and substantially horizontal.

  The air sent diagonally upward from the blower outlet 5 circulates along the ceiling wall S due to the Coanda effect, and reaches the side wall W2 (see FIG. 35) facing the indoor unit 1 while diffusing. And it falls along side wall W2, distribute | circulates the floor surface F (refer FIG. 35), and conditioned air distribute | circulates the whole inside of the room R. FIG. As a result, the room is cooled to a uniform temperature.

  As will be described in detail later, when the wind speed of the air sent from the outlet 5 is increased, the conditioned air is guided to a long distance while maintaining a low temperature during the cooling operation. For this reason, the temperature farther from the indoor unit 1 is lower than that closer.

<Second air flow control>
Next, the second airflow control is performed when the regions obtained by dividing the room into left and right by the operation unit 31a are set to different temperatures. The display unit 31b of the remote controller 31 shown in FIG. 23 described above sets the set temperature of the left first area E1 (see FIG. 29) toward the indoor unit 1 to 24 ° C., and the right second area E2 (see FIG. 23). 29) is set to 26 ° C. The first and second regions E1 and E2 are divided by a vertical plane that divides the indoor unit 1 into left and right.

  When the cooling operation is started at the set temperature, the vertical louvers 12a and 12b are arranged as shown in FIG. That is, the right vertical louver 12b is arranged in a direction toward the front. The left vertical louver 12a is arranged, for example, inclined at 40 ° to the left as it goes forward. For example, the right vertical louver 12b may be inclined slightly to the right by 5 °, for example, in the range where the inclination angle is smaller than that of the vertical louver 12a.

  The right side of the horizontal louvers 113a and 113b is arranged in the same manner as in FIG. That is, the upper lateral louver 113a is disposed at an angle of 20 ° with respect to the horizontal, for example, so that the front is upward. The lower lateral louver 113b is disposed at an angle of 5 ° or less with respect to the horizontal, for example, between the obliquely lower side where the front is slightly lower and substantially horizontal.

  Further, the left side of the horizontal louvers 113a and 113b is arranged as shown in FIG. That is, the horizontal louvers 113a and 113b are arranged between an obliquely lower side and a substantially horizontal side, which is slightly lower as it goes to the front. For example, the left side of the horizontal louver 113a is arranged substantially horizontally, and the left side of the horizontal louver 113b is arranged so that the front is 10 ° below the horizontal. FIG. 27 is a perspective view of the indoor unit 1 showing this state.

  Then, similarly to the first airflow control, the wind speed is set to “slight wind”, the blower fan 7 is driven, and conditioned air is sent out from the blowout port 5 as shown in FIG. That is, the conditioned air is sent from the left outlet 5a toward the left substantially horizontal or slightly leftward as indicated by the arrow A. In addition, it is sent while being inclined leftward by an inclination angle α with respect to a vertical plane that divides the indoor unit 1. As shown by the arrow B, conditioned air is sent from the right outlet 5b obliquely upward in the front.

  FIG. 29 shows the flow state of the air sent into the room. Air (B) airflow (hereinafter referred to as “second airflow”) delivered from the right outlet 5b circulates along the ceiling wall S due to the Coanda effect while diffusing left and right, and gradually decreases the speed. And it falls along the wide range of the side wall W2 facing the indoor unit 1.

  The airflow (A) sent from the left outlet 5a (hereinafter referred to as “first airflow”) flows along the left side wall W3 toward the indoor unit 1 and reaches the side wall W2. Then, the second airflow merges with the first airflow and circulates on the floor surface F.

  The inclination angle α (see FIG. 28) of the first airflow is preferably 20 ° or more. When the indoor unit 1 is provided at the center of the shorter side wall W1 with the room R in FIG. 29 between 6 tatami mats, the direction from the center of the indoor unit 1 to the corner where the side walls W2 and W3 intersect is a vertical plane perpendicular to the side wall W1. Inclined about 20 °. Therefore, when the inclination angle α of the first airflow is set to 20 ° or more, the first airflow can be reliably made to follow the side wall W3. When the room R is between 8 tatami mats or when the indoor unit 1 is in front and horizontally long, the inclination angle α can be set to be larger than 20 ° along the side wall W3.

  Since the second air flow (B) is sent out toward the front, the first region E1 on the left side of the room R and the second region E2 on the right side of the room R are cooled with the same cooling capacity by the second air flow (B). On the other hand, since the first air flow (A) is sent leftward, the first air flow (A) cools the first region E1 on the left side of the room R more than the second region E2. As a result, the average temperature of the first region E1 is lower than the average temperature of the second region E2.

  For example, when ½ each of conditioned air is sent out from the left outlet 5a and the right outlet 5b, the first and second regions are each ¼ of the conditioned air sent out from the outlet 5 by the second air flow. It is cooled with each cooling capacity. In addition, the first region is cooled by the first airflow with a cooling capacity of about ½ of the conditioned air sent from the blowout port 5. Thereby, the cooling capacity of 3/4 of the conditioned air sent from the blower outlet 5 is supplied to the first region.

  Further, since the vertical louver 12a is inclined as shown in FIG. 25, the first air flow (A) sent out from the left outlet 5a has an air volume due to an increase in pressure loss and a decrease in cross-sectional area due to the vertical louver 12a. Decrease. For this reason, the temperature of the first air stream (A) becomes lower than the second air stream by heat exchange with the indoor heat exchanger 9. Therefore, the average temperature of the first region E1 can be further lowered than the average temperature of the second region E2.

  30 to 33 show the temperature distribution in the room R during the second airflow control. The size of the room R is 6 tatami mats (height 2400 mm, width 3600 mm, depth 2700 mm). 30 to 33 show the measurement results of the cross sections of the alternate long and short dash lines D1 and D2 and two-dot chain lines D3 and D4 in FIG.

  The D1 cross section is a position parallel to the side wall W3 and 675 mm from the side wall W3, and is a cross section at a position on the left side of the indoor unit 1 in the room R. The cross section D2 is a position parallel to the side wall W4 facing the side wall W3 and 675 mm from the side wall W4, and is a cross section at a position on the right side ¼ toward the indoor unit 1 in the room R. The cross section D3 is a position parallel to the side wall W1 and 1200 mm from the side wall W1, and is a cross section at a position 1/3 ahead of the indoor unit 1 in the room R. The D4 cross section is a cross section at a position parallel to the side wall W2 facing the side wall W1 and 1200 mm from the side wall W2, and at a position 1/3 rearward toward the indoor unit 1 in the room R.

  According to these figures, the temperature of the first region E1 on the left side of the room R toward the indoor unit 1 is controlled to about 24 ° C. In addition, the temperature of the second region E2 on the right side of the indoor unit 1 is controlled to about 26 ° C. Therefore, the temperature difference between the first and second regions E1 and E2 can be set at about 2 ° C.

  At this time, air flows from the side wall W2 toward the side wall W1 in the living space in the lower central portion of the room R. For this reason, the air sent out from the blower outlet 5 is decelerated, the wind speed of 1st area | region E1 is 0.1 m / s or less, and the wind speed of 2nd area | region E2 is about 0.2 m / s. Therefore, cold air does not directly pour into the living space, and an extremely low-speed airflow flows, so that it is possible to prevent the health of the user from being impaired. If the wind speed is 0.5 m / s or less, the user feels almost no wind. For this reason, the rotation speed of the ventilation fan 7 is determined so that the wind speed of living space may be 0.5 m / s or less.

The first air stream (A) has an air volume of 2.5 m ³ / min, the wind speed is 3 m / s, and the blowing temperature is 10 ° C. The second air stream (B) has an air volume of 5 m ³ / min, and the wind speed is 6 m / s. s, the blowing temperature is 15 ° C. As described above, the air volume and the wind speed are different due to pressure loss and the like, and the blowing temperature of the first air stream (A) is low. Moreover, since the wind speed of 1st airflow is low, the quantity of the conditioned air which circulates from the 1st area | region E1 to the 2nd area | region E2 reduces, and the quantity stagnated in the 1st area | region E1 increases. Thereby, the temperature of the first region E1 can be made lower than that of the second region E2 more easily.

  The heat exchanger 9 may be divided into left and right parts so that the respective heat exchangers have different temperatures, and a temperature difference between the first and second airflows may be provided. Further, the blower fan 7 may be divided into left and right, and the respective blower fans may have different rotation speeds, and the first and second airflows may have different wind speeds and air volumes. Thus, the temperature of the first and second regions can be adjusted more finely.

  Moreover, since conditioned air is sent in different directions from the left and right left outlets 5a and 5b of the outlet 5, comfort can be improved. That is, when conditioned air is sent in different directions from above and below the air outlet 5, a temperature difference is generated between the upper and lower surfaces of the horizontal louver. As a result, condensation may occur on the horizontal louver, and water may be sprayed on the user or the user may be uncomfortable by flooding the room. On the other hand, if conditioned air is sent from the left air outlet 5a and the right air outlet 5b in different directions, the occurrence of a temperature difference between the upper and lower surfaces of the horizontal louvers 113a and 113b is suppressed, and condensation is prevented and comfort is improved.

<Third airflow control>
When the temperature difference between the first and second regions E1 and E2 is set larger by operating the remote controller 31, the third airflow control is performed. In the third airflow control, the vertical louver 12a and the horizontal louvers 113a and 113b are arranged in the same manner as in the second airflow control. The right vertical louver 12b is disposed such that the front is inclined toward the inner side (left side).

  Since the vertical louver 12b is arranged with the front inclined toward the inner side (left side), the second air flow (B) sent from the right outlet 5b is on the left side of the second region E2 on the right side of the room R. Are sent more in the first area E1. For this reason, more cooling capacity is provided in the first region E1 on the left side than the second region E2 on the right side of the room R. However, since the total amount of air sent out from the blower outlet 5 decreases, the rotational speed of the blower fan 7 is increased and the air volume is increased. Further, the absolute room temperature of the first and second regions E1 and E2 is adjusted by changing the rotational speed of the compressor (not shown).

  For example, when the set temperatures of the first and second regions E1 and E2 are 23 ° C. and 26 ° C., respectively, the right vertical louver 12b is 10 ° toward the inside (left side) with respect to the first airflow control. Inclined. Further, the rotational speed of the blower fan 7 is set to 110%, and the rotational speed of the compressor (not shown) is set to 105%.

  When the set temperatures of the first and second regions E1 and E2 are 22 ° C. and 26 ° C., respectively, the right vertical louver 12b is inclined 20 ° toward the inside (left side) with respect to the first airflow control. Arranged. Further, the rotational speed of the blower fan 7 is set to 120%, and the rotational speed of the compressor (not shown) is set to 110%.

  As described above, the vertical louver 12b is disposed so that the inclination angle α is inclined toward the inner side (left side), and the air volume sent to the first area E1 of the second airflow (B) is increased to increase the first area E1. The cooling capacity increases, and the temperature of the first region E1 becomes lower than that of the second airflow control. Thereby, the temperature difference of 1st, 2nd area | region E1, E2 can be enlarged. Therefore, the first and second regions E1 and E2 are independently brought to a desired temperature by increasing or decreasing the ratio of the amount of air sent to the first region E1 and the second region E2 depending on the wind direction of the second airflow (B). The temperature can be controlled.

  Moreover, you may increase / decrease the ratio of a 1st airflow by further subdividing the vertical louvers 12a and 12b divided into right and left. Blower fans may be provided on the left and right sides to individually vary the air volumes of the first and second airflows.

  In the second and third airflow control, the case where the first region E1 is set to a temperature lower than that of the second region E2 is described. However, the vertical louvers 12a and 12b and the horizontal louvers 113a and 113b are symmetrical to each other. By disposing the second region E2, the temperature of the second region E2 can be made lower than that of the first region E1.

<Fourth air flow control>
Next, the fourth airflow control is performed when the regions obtained by dividing the room into the front and rear by the operation unit 31a are set to different temperatures. In FIG. 34, the set temperature of the first area E3 (see FIG. 35) on the side close to the indoor unit 1 is set to 26 ° C. by the operation of the remote controller 31, and the set temperature of the second area E4 (see FIG. 35) on the far side. Is set to 24 ° C. The first and second regions E3 and E4 are divided by a vertical plane that divides the central portion of the room R.

  When the cooling operation is started at this set temperature, the vertical louvers 12a and 12b are arranged toward the front as in FIG. The vertical louvers 12a and 12b may be inclined in a range up to about 5 ° with the front facing outward. Further, the lateral louvers 113a and 113b are arranged in the same manner as in FIG. 24 described above, without the left and right ends being twisted at the same rotational position. That is, the upper lateral louver 113a is disposed at an angle of 20 ° with respect to the horizontal, for example, so that the front is upward. The lower horizontal louver 113b is disposed at an angle of, for example, 5 ° or less with respect to the horizontal between an obliquely lower side and a substantially horizontal side where the front is slightly lower.

  And the rotation speed of the ventilation fan 7 is set to 140% with respect to the time of 1st airflow control, and conditioned air is sent out diagonally upward from the blower outlet 5. FIG. At this time, the blowing wind speed is equivalent to “weak wind” (in the case of a 6 tatami type air conditioner, for example, 6 m / s). As shown in FIG. 35, the air sent obliquely upward from the blower outlet 5 circulates along the ceiling wall S by the Coanda effect, and reaches the side wall W2 facing the indoor unit 1 while diffusing. Then, it descends along the side wall W <b> 2 and flows through the floor surface F.

  At this time, since the blown wind speed is high, the conditioned air does not rise in temperature while circulating along the ceiling wall S, and reaches far while maintaining a low temperature. For this reason, the average temperature of the 1st field E3 near the outdoor unit 1 becomes higher than the average temperature of the 2nd field E4 on the far side.

  FIG. 36 shows the temperature distribution in the room R during the fourth airflow control. The size of the room R is 6 tatami mats (height 2400 mm, width 3600 mm, depth 2700 mm) as described above. FIG. 36 shows the measurement result of the central section of the room R indicated by the alternate long and short dash line D shown in FIG.

  According to the figure, the temperature of the first region E3 of the room R near the indoor unit 1 is controlled to about 26 ° C. Further, the temperature of the second region E4 far from the indoor unit 1 is controlled to about 24 ° C. Therefore, the temperature difference between the first and second regions E3 and E4 can be set to about 2 ° C.

  At this time, air flows from the side wall W2 toward the side wall W1 in the living space in the lower central portion of the room R. For this reason, the air sent out from the blower outlet 5 is decelerated, and the wind speed of a living space is 0.1 m / s or less. Therefore, cold air does not directly pour into the living space, and an extremely low-speed airflow flows, so that it is possible to prevent the health of the user from being impaired.

<Fifth air flow control>
When the temperature difference between the first and second regions E3 and E4 is set to be larger by the operation of the remote controller 31, the fifth airflow control is performed. In the fifth airflow control, the vertical louvers 12a and 12b and the horizontal louvers 113a and 113b are arranged in the same manner as in the fourth airflow control. The number of rotations of the blower fan 7 is increased, and the wind speed of the blown airflow is increased. Further, the absolute room temperature of the first and second regions E3 and E4 is adjusted by changing the rotational speed of the compressor (not shown).

  For example, when the set temperatures of the first and second regions E3 and E4 are 23 ° C. and 26 ° C., respectively, the rotational speed of the blower fan 7 is set to 150% with respect to the first airflow control, and the compressor (not The number of rotations (shown) is set to 105%. When the set temperatures of the first and second regions E3 and E4 are 22 ° C. and 26 ° C., respectively, the rotational speed of the blower fan 7 is set to 160% with respect to the first airflow control, and the compressor (not The number of rotations (shown) is set to 110%.

  If the wind speed sent out from the blower outlet 5 increases, low-temperature conditioned air reaches farther. Thereby, the temperature difference of 1st, 2nd area | region E3, E4 can be enlarged more. Therefore, by varying the wind speed at the time of blowing, the first and second regions E3 and E4 can be independently temperature controlled to a desired temperature.

<Sixth airflow control>
Next, the sixth airflow control is performed when the regions obtained by dividing the room vertically by the operation unit 31a are set to different temperatures. In FIG. 37, the set temperature of the first region E5 (see FIG. 39) in the upper part of the room is set to 26 ° C. by operating the remote controller 31, and the set temperature of the second region E6 (see FIG. 39) on the far side is set to 24 ° C. The state set to is shown. The first and second regions E5 and E6 are divided by a horizontal plane that divides the central portion of the room R.

When the cooling operation is started at this set temperature, the vertical louvers 12a and 12b are arranged toward the front as in FIG. The vertical louvers 12a and 12b may be inclined in a range up to about 5 ° with the front facing outward. Further, the lateral louvers 113a and 113b are arranged as shown in FIG. 38 without twisting the left and right ends at the same rotational position. That is, the upper lateral louver 113a is disposed so as to rotate and shield the upper part of the outlet 5. The lower lateral louver 113b is set to rotate so that the lower end is between the substantially lower direction and the rear lower side with respect to the upper end.

  And the rotation speed of the ventilation fan 7 is set to 80% with respect to the time of 1st airflow control, and conditioned air is sent out from a blower outlet 5 in the substantially downward direction or the downward back. At this time, the blowing wind speed is smaller than the “light wind”. As shown in FIG. 39, the air sent from the blower outlet 5 substantially directly downward or rearwardly descends along the side wall W <b> 1 where the indoor unit 1 is installed and flows through the floor surface F.

  At this time, if the wind speed at the time of blowing is high, the air that has circulated through the floor F rises and circulates up the side wall W2. The vicinity of W1 and the floor surface F becomes a low temperature. For this reason, the average temperature of the 1st field E5 of the upper part of outdoor unit 1 becomes higher than the average temperature of the 2nd field E6 of the lower part.

  FIG. 40 shows the temperature distribution in the room R during the airflow control. The size of the room R is 6 tatami mats (height 2400 mm, width 3600 mm, depth 2700 mm) as described above. FIG. 40 shows the measurement result of the central section of the room R indicated by the alternate long and short dash line D shown in FIG.

  According to the figure, the first area E5 on the ceiling side of the room R is about 25 ° C to 27 ° C, and the average temperature is controlled to about 26 ° C. Moreover, the 2nd area | region E6 by the side of the floor F of the room R is about 23 to 25 degreeC, and the average temperature is temperature-controlled at about 24 degreeC. Therefore, the temperature difference between the first and second regions E5 and E6 can be set to about 2 ° C.

  At this time, the air sent out from the blower outlet 5 at a low speed is decelerated when it flows along the side wall W1, and the wind speed of the living space in the lower central part of the room R is 0.1 m / s or less. Further, since the airflow does not reach the upper part of the room R, the upper wind speed is also 0.1 m / s or less. Therefore, cold air does not directly pour into the living space, and an extremely low-speed airflow flows, so that it is possible to prevent the health of the user from being impaired.

<Seventh airflow control>
When the temperature difference between the first and second regions E5 and E6 is set to be larger by the operation of the remote controller 31, the seventh airflow control is performed. In the seventh airflow control, the vertical louvers 12a and 12b and the horizontal louvers 113a and 113b are arranged in the same manner as in the sixth airflow control. The rotational speed of the blower fan 7 is reduced, and the wind speed of the blown airflow is reduced. Further, the absolute room temperature of the first and second regions E5 and E6 is adjusted by changing the rotational speed of the compressor (not shown).

  For example, when the set temperatures of the first and second regions E5 and E6 are 23 ° C. and 26 ° C., respectively, the rotational speed of the blower fan 7 is set to 70% with respect to the first airflow control, and the compressor (not The number of rotations (shown) is set to 105%. When the set temperatures of the first and second regions E5 and E6 are 22 ° C. and 26 ° C., respectively, the rotational speed of the blower fan 7 is set to 60% with respect to the first air flow control, and the compressor (not The number of rotations in the figure is set to 110%.

  If the wind speed of the conditioned air sent out from the blower outlet 5 decreases, the low-temperature conditioned air will not rise further on the opposite side wall W2. Thereby, the temperature difference of 1st, 2nd area | region E5, E6 can be enlarged more. Therefore, the first and second regions E5 and E6 can be independently controlled to a desired temperature by varying the wind speed at the time of blowing.

  According to the present embodiment, the first regions E1, E3, E5 and the second regions E2, E4, E6 divided into the interior can be set to substantially the same temperature, and each can be independently heated to a desired temperature. Can be controlled. Therefore, even when the temperature at which a plurality of users feel comfortable differs, each user can be divided into the first and second regions to satisfy the comfort of each user.

  For example, when a user who prefers an environment of 22 ° C. and a user who prefers an environment of 28 ° C. are in one room in the conventional cooling operation, set the temperature to 28 ° C. according to the latter and cool the former. Continue to apply directly. As a result, the former continues to be directly exposed to the cold and loses physical condition. Also, the set temperature is set to 22 ° C. according to the former, and the latter is made to wear a lot of clothes. As a result, if the latter stays in the room for a long period of time, a so-called “bottom cold” is felt and the physical condition is impaired. The present embodiment can provide a comfortable environment by preventing the physical condition of both from being impaired.

  Moreover, since the horizontal louvers 113a and 113b are made of a twistable member that can be twisted, air can be easily sent from one and the other of the outlets 5 in different directions. Thereby, the area | region which divided | segmented the room | chamber interior can be made into desired different temperature. In addition, since the center in the longitudinal direction of the horizontal louvers 113a and 113b is not divided, it is possible to prevent a loss of aesthetics, and it is possible to prevent condensation due to the turbulence of the air flow in the divided portions.

<< Second Embodiment >>
Next, FIG. 41 is a perspective view showing the indoor unit 1 of the air conditioner of the second embodiment. For convenience of explanation, the same reference numerals are given to the same parts as those in the first embodiment shown in FIGS. In this embodiment, a horizontal louver 113c made of a non-twistable member is provided instead of the lower horizontal louver 113b of the first embodiment. Other parts are the same as those in the first embodiment.

  The lateral louver 113c is formed of a single plate-shaped resin molded product or the like, and is a non-twistable member that cannot be twisted like the lateral louver 113a.
