There is a mist generator that performs a mist operation that blows humidified air containing nano mist and negative ions from the air outlet to the outside of the equipment body by a blower fan, and the humidification amount and air volume are adjusted according to the humidity in the room and the set mode. By adjusting and changing the relative humidity in the room where the equipment body is placed, the room was kept at the set humidity. (For example, Patent Document 1)

JP 2015-222156

However, in this conventional one, the amount of humidified air that passes through the water storage chamber and the air-water separation air passage and is blown from the air outlet due to pressure loss decreases, so the room in which the instrument body is installed is humidified with a large amount of air. There is a problem that it takes a long time for the humidity in the room to reach an appropriate value even if the mist operation with the maximum air volume is performed when the air cannot be blown and the air in the room is extremely dry. , There was room for improvement.

In order to solve the above problems, in claim 1 of the present invention, the appliance main body, the blower fan installed in the appliance main body and blowing air, and the air outside the appliance main body formed in the vicinity of the blower fan are blown.

An air-water separation means for separating large-diameter water droplets contained in humidified air, an upper air passage connected to the downstream side of the air-water separation air passage, and an upper air passage into which the humidified air that has passed through the air-water separation air passage flows in. A louver is installed on the downstream side of the upper air passage, and a blower port for blowing the humidified air in the upper air passage to the outside of the main body of the appliance is provided.
A bypass inflow port through which dry air before being humidified into the air-water separation air passage is formed in the air-water separation air passage on the downstream side of the air-water separation means from the air passage path without passing through the water storage chamber. Then, in the upper air passage, a guide means for guiding the dry air flowing in from the bypass inlet to merge with the humidified air, and the humidified air after merging with the dry air enter the air outlet. It is characterized by being equipped with a rectifying means that rectifies the air so that it is blown with a uniform air volume.

Further, in claim 2, the air outlet is formed so that the humidified air is blown from the upper front surface of the instrument body, and the rectifying means has a vertical surface that partitions at least the inside of the upper air passage in the vertical direction.

According to the present invention, a bypass inflow port through which dry air can flow in before being humidified into the air-water separation air passage from the air flow path without passing through the water storage chamber is made into the air-water separation air passage on the downstream side of the air-water separation means. Since it was formed, the dry air flows in from the bypass inlet that bypasses the water storage chamber where the air pressure loss is large, and the humidified air is blown from the air outlet with a large amount of air to bring the indoor humidity to an appropriate value in a short time. In addition, in the upper air passage, a guide means for guiding the dry air flowing in from the bypass inlet to merge with the humidified air, and the humidified air after merging with the dry air are uniformly distributed from the air outlet. Since it is equipped with a rectifying means that rectifies the air so that it is blown with a large amount of air, the dry air and the humidified air are not separately blown from the air outlet, reducing the humidification efficiency of the room where the equipment body is installed. In addition to being able to prevent this, the humidified air is blown from the air outlet to the room with a uniform air volume, so that the user or the like existing near the air outlet does not feel uncomfortable.

In addition, the air outlet is formed so that humidified air is blown from the upper part of the front surface of the main body of the appliance, and the rectifying means has at least a vertical plane that vertically partitions the inside of the upper air passage and a horizontal direction in the upper air passage.

Since it circulates evenly in the air passage and is guided to the air outlet, it prevents unevenness in the amount of humidified air blown from the air outlet, and the humidified air is blown from the air outlet with a uniform air volume. Therefore, it does not give a sense of discomfort to the users and the like existing near the air outlet.

It is formed so as to penetrate the wall surface of the air-water separation air passage 17 which faces the upwardly inclined inclined surface P of the baffle plate 18a installed at the uppermost stage in the water separation air passage 17 and faces the air passage 15. As the air flows into the air-water separation air passage 17 from the bypass inlet 51, the air volume of the humidified air rising from the water storage chamber 8 is increased, and the humidified air blown into the room from the air outlet 2 is increased. The amount of air blown can be increased.

It merges with the rising humidified air.

Next, the operation from the start to the end of the operation in this one embodiment will be described with reference to the flowchart of FIG.
First, when the operation switch 30 of the operation unit 6 is operated or the operation start time set by the timer changeover switch 33 is reached, the control unit 45 opens the drain valve 26 to drain the water in the water storage chamber 8. Then, when the OFF signal is detected by the water level sensor 21, the water supply valve 23 is opened to perform a cleaning operation of flushing the inside of the water storage chamber 8 with water, and when a predetermined time elapses, the drain valve 26 is closed to flow in from the water supply valve 23. When the water level sensor 21 detects an ON signal, a water replacement mode is performed in which the water supply valve 23 is closed, assuming that a predetermined amount of water has been supplied into the water storage chamber 8 (step S101). ).

When the water replacement mode in step S101 is completed, the control unit 45 turns on the heater 19 by the heater control means 48 until the water storage temperature detected by the water storage temperature sensor 20 becomes the same value as room temperature, and the mist motor 11 And the start-up mode for executing the start-up operation controlled by the mist motor control means 46 and the blower fan control means 47 so that the blower fan 14 has a predetermined rotation speed is performed (step S102).

When the start-up mode of step S102 is completed, the control unit 45 causes the mist motor 11 and the blower fan 14 to rotate at a predetermined speed based on the humidification level and the air volume level set by the humidification switch 31 and the air volume switch 32. The rotation speed is controlled by the mist motor control means 46 and the blower fan control means 47 so as to be driven, and the ON / OFF state of the heater 19 is switched and controlled by the heater control means 48 to obtain a humidification level and an air volume level. A normal operation mode for executing a mist operation within a predetermined temperature range is performed (step S103).

When it is determined that the operation switch 30 is operated during the normal operation mode of step S103 and an instruction to end the operation is given, the control unit 45 stops the mist motor 11 and then opens the drain valve 26 to enter the water storage chamber 8. Water is drained, and after a predetermined time has passed, the water supply valve 23 is opened to clean the inside of the water storage chamber 8, then the drain valve 26 is closed to perform a water replacement operation for storing a predetermined amount of water in the water storage chamber 8, and then a water replacement operation is performed. A sterilization operation for sterilizing water by heating water with the heating heater 19 turned on is performed for a predetermined time, and then a cooling operation for cooling the inside of the water storage chamber 8 is executed after a lapse of a predetermined time, and the water storage temperature becomes a predetermined temperature. When the following occurs, the drain valve 26 is opened to perform a cleaning mode for draining water (step S104).

When the cleaning mode in step S104 is completed, the control unit 45 controls the blower fan control means 47 so that the blower fan 14 is driven at a predetermined rotation speed (for example, 800 rpm), and blows air into the water storage chamber 8 and the blower path 15. A drying mode is performed to prevent the growth of bacteria by drying (step S105), it is determined whether the driving time of the blower fan 14 has counted a predetermined time (for example, 3 hours), and after counting for 3 hours, the blower fan 14 To stop the operation.

Next, the air passage of the humidified air during the mist operation and the air passage in which the dry air flowing in from the bypass inlet 51 merges with the humidified air and is blown into the room will be described in detail.
First, when the mist operation is started and the mist motor 11 and the blower fan 14 are driven at a predetermined rotation speed, the dry air in the room is sucked from the suction ports 49 on the bottom surface and the front surface of the instrument main body 1 and passes through the air cleaning filter 50. The air becomes clean with the dust in the air removed.
Then, as shown in FIGS. 6 and 7, the dry air that has passed through the air purification filter 50 rises in the air passage 15 and is divided into the wind tunnel 16 side and the bypass inflow port 51 side.

The air inflow amount of the dry air divided into the wind tunnel 16 side and the bypass inflow port 51 side varies depending on the opening area between the wind tunnel 16 and the bypass inflow port 51, and the air inflow amount is proportional to the increase in the opening area. Will also increase. Therefore, the wind tunnel so that the amount of air blown into the room is appropriately increased while ensuring a sufficient amount of air that can guide the humidified air containing fine mist and negative ions generated in the water storage chamber 8 to the air outlet 2. Design the opening area of 16 and the bypass inlet 51.

The dry air that has flowed into the water storage chamber 8 from the wind tunnel 16 is pumped by the rotating body 10 and crushed by the perforated portion 13 to generate humidified air containing fine mist, large-diameter water droplets, and negative ions. Ascend road 17.
When ascending the air-water separation air passage 17, the flow path meanders due to the baffle plates 18a, 18b, and 18c, and the large-diameter water droplets in the humidified air flow by licking the inclined surface P of each baffle plate 18. When it adheres to the surface of the baffle plate 18 and reaches the lower end of each inclined baffle plate 18, water droplets fall into the water storage chamber 8 due to gravity, so that the amount of large-diameter water droplets carried to the air outlet 2 can be reduced. ..

On the other hand, the dry air flowing into the bypass inflow port 51 from the air passage 15 rises in the air-water separation air passage 17 along the baffle plate 18a, and the guide plate 54 makes the back surface of the instrument main body 1 in the direction opposite to the air outlet 2. You will be guided to the side.

Then, as shown in FIG. 8, the humidified air that has risen from the water storage chamber 8 through the air-water separation air passage 17 and the dry air that has flowed in from the bypass air passage 51 and is guided to the back side of the instrument main body 1 by the guide plate 54. However, the humidified air merged in the upper air passage 52 on the back side of the instrument main body 1, and the combined humidified air was diverted and circulated in the upper air passage 52 by the rectifying plate 53 installed in the upper air passage 52, and the louver 3 Air is blown into the room from the openings of the air outlets 2 partitioned by the above.

In this way, by forming the bypass air passage 51 through which the air flowing through the air passage 15 can flow into the side surface of the air-water separation air passage 17, the air passage chamber 8 and the air-water separation air passage 17 are passed through and humidified by pressure loss. Even if the air volume decreases, air that is not affected by pressure loss flows in from the bypass air passage 51, merges with the humidified air in the upper air passage 52, and is supplied into the room from the air outlet 2, so that the suction port 49 Even if the ventilation resistance is increased by attaching the air cleaning filter 50 to the room, the amount of humidified air supplied to the room is not reduced, and humidification and air cleaning can be effectively performed.

Further, since the large-diameter water droplets contained in the humidified air passing through the air-water separation air passage 17 during mist operation have a larger mass than the fine mist, it is difficult for the air-water separation air passage 17 to rise due to the influence of gravity. , It easily adheres to the wall surface below the air-water separation air passage 17 near the water storage chamber 8 and the baffle plates 18b and 18c. Therefore, by forming the bypass inflow port 51 at a position facing the inclined surface P of the baffle plate 18a located at the uppermost part of the air-water separation air passage 17 closest to the air outlet 2, large-diameter water droplets reach the air outlet 2. The amount of guidance is reduced, and it is possible to prevent the vicinity of the air outlet 2 from getting wet with the dew condensation water and the lower part of the instrument main body 1 from getting wet.

Further, since the air-water separation air passage 17 is installed so as to face vertically upward, when a large-diameter water droplet adhering to the baffle plate 18 falls from the end of the baffle plate 18, it flows into the water storage chamber 8, so that the instrument main body 1 Water does not leak from the exterior of the fixture, and the installation surface of the appliance body 1 can be prevented from getting wet.

Further, by installing the guide plate 54 in the upper air passage 52 on the front side of the instrument main body 1 in the vicinity of the upper end of the air-water separation air passage 17 so as to be parallel to the installation surface of the instrument main body 1, the bypass flow. Since it is possible to prevent the dry air flowing into the air-water separation air passage 17 from the inlet 51 from being blown into the room from the air outlet 2 without merging with the humidified air, the humidified air can be prevented from being blown into the room from the air outlet 2. And the dry air are not separated and blown, and the room in which the instrument body 1 is installed can be effectively humidified.

Further, as shown in FIG. 8, the straightening vane 53 installed in the upper air passage 52 has a vertical surface 53a that vertically partitions the upper air passage 52 and a horizontal plane 53b that horizontally partitions the upper air passage 52. A predetermined distance R1 between the inner wall surface 52a on the back side of the upper air passage 52 on the back side of the instrument body 1 and the vertical surface 53a, and the upper air passage on the upper surface side of the instrument body 1 A predetermined distance R2 is formed between the inner wall surface 52b on the upper surface side of the 52 and the horizontal plane 53b.

As a result, the humidified air that has merged with the dry air near the connecting surface between the air-water separation air passage 17 and the upper air passage 52 is on the front side of the vertical plane 53a and the lower side of the horizontal plane 53b with respect to the installation surface of the instrument body 1. The flowing air A that passes through and is mainly blown into the room from the lower side of the air outlet 2, and the air that passes through the back side of the vertical plane 53a and the upper side of the horizontal plane 53b and is mainly blown into the room from the upper side of the air outlet 2. Divide into the circulating air B.

The air volume balance of the humidified air blown into the room from the air outlet 2 is determined so that the air volume is not biased in the vertical vertical direction of the air outlet 2 because the air volume of the flowing air B changes depending on the predetermined distances R1 and R2. By determining the distances R1 and R2 and installing the rectifying plate 53, the air volume in the vertical and vertical directions of the air outlet 2 becomes uniform and the air can be blown into the room. Therefore, the user who exists especially near the air outlet 2. Etc. do not feel uncomfortable with the feeling of blowing air from the blowing port 2, and further, the detection accuracy of the blowing temperature sensor 27 can be maintained high.

As described above, in the case where the bypass inflow port 51 is formed so that the dry air blown by the blower fan 14 and flowing through the blower path 15 can flow into the air-water separation air passage 17 without flowing into the air cavity 16 is formed. The guide plate 54 that guides the flow direction of the dry air that has flowed into the air passage 52 from the bypass inflow port 51 toward the flow direction of the humidified air and merges the dry air and the humidified air, and rectifies the humidified air that has merged with the dry air. By providing a rectifying plate 53 that equalizes the air volume of the humidified air blown from the air outlet 2, the air volume of the humidified air blown from the air port 2 into the room is increased to improve the humidification efficiency, and the air is blown. Since the humidified air is blown uniformly from the air outlet 2, the humidity distribution in the room is not biased, and the person who exists near the air outlet 2 does not feel any discomfort with the air blown from the air outlet 2. ..

In this embodiment, the bypass inflow port 51 is formed on the side wall surface of the air-water separation air passage 17, but the present invention is not limited to this, so that air can flow from the air passage 15 to the upper air passage 52. A through hole was formed at an appropriate position on the lower surface of the upper air passage 52, and the air flowing in the air passage 15 during mist operation was divided into the water storage chamber 8 and the upper air passage 52, respectively, and passed through the air-water separation air passage 17. The humidified air and the air that has passed through the bypass inlet 51 may be mixed in the upper air passage 52 and blown from the air outlet 2, that is, they pass through the water storage chamber 8 and the air-water separation air passage 17. If the configuration is such that the air is mixed with the humidified air without being affected by the pressure loss and the amount of air blown from the air outlet 2 is increased, the formation position of the flow path that bypasses the water storage chamber 8 and the air-water separation air passage 17. Is not specified.

Further, in the present embodiment, the baffle plate 18 has been used as the air-water separation means, but the present invention is not limited to this, and fine water droplets are separated while separating the large-diameter water droplets flowing in the air-water separation air passage 17. Any configuration may be sufficient as long as the contained humidified air can be blown up to the air outlet 2. For example, a plurality of net-like plates or plates having punch holes formed in the air-water separation air passage 17 are provided to form fine water droplets. The configuration may be such that large-diameter water droplets can be separated while ensuring ventilation so that the contained humidified air can flow.

Further, the other configurations used in the present embodiment are presented as an example, and are not intended to limit the scope of the invention, and can be implemented in various other embodiments. Various omissions, replacements, and changes can be made without departing from the gist of. These embodiments and modifications thereof are included in the scope and gist of the invention, and are also included in the scope of the invention described in the claims and the equivalent scope thereof.
