[Embodiment 1]
An embodiment of the humidity control device 100 according to the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a perspective view showing a humidity control device 100 according to the present embodiment. FIG. 2 is a diagram showing a cross section of II-II of the humidity control device 100 shown in FIG. The humidity control device 100 is arranged indoors, for example. Specifically, the humidity control device 100 is arranged on the floor of the room.

The humidity control device 100 has, for example, a dehumidifying function and a humidifying function. In the dehumidifying function, the humidity control device 100 sucks in the air around the humidity control device 100, removes the moisture contained in the sucked air, and blows out the air. The humidity control device 100 can dry clothes by blowing dehumidified air (wind) onto the clothes. In the humidification function, the humidity control device 100 increases the moisture contained in the air sucked by the humidity control device 100 and blows out the air.

As shown in FIG. 1, the humidity control device 100 includes an operation unit 8, a housing 10, and a louver 11. The operation unit 8 is provided on the upper part of the housing 10. The operation unit 8 receives an instruction from the outside. Specifically, the user switches modes such as a dehumidification mode and a drying mode, and instructs each operation mode such as wind direction control and air volume control via an operation button (not shown) of the operation unit 8.

The housing 10 is a hollow member. The material of the housing 10 includes, for example, sheet metal or synthetic resin. However, the material of the housing 10 is not particularly limited. The housing 10 includes a front cover 5, a rear cover 6, a pair of side plates 7, and a handle 9. Note that in FIG. 1, only one of the pair of side plates 7 is shown, and the other of the pair of side plates 7 is hidden.

The front cover 5 is located so that the user mainly uses the humidity control device 100. The rear cover 6 is arranged so as to face the front cover 5. The side plate 7 is located between the front cover 5 and the rear cover 6. The handle 9 is formed on each of the pair of side plates 7. The user grabs the handle 9 and lifts the humidity control device 100.

As shown in FIG. 2, the housing 10 has an inlet 14 and an outlet 10h. Specifically, the rear cover 6 of the housing 10 has a plurality of inflow ports 14. The air around the rear cover 6 flows into the inside of the humidity control device 100 through the inflow port 14. The outlet 10h is located on the top surface of the housing 10. The outlet 10h communicates the inside and the outside of the housing 10. The air moving inside the housing 10 flows out from the outlet 10h. That is, the airflow moving inside the housing 10 flows out from the outlet 10h. The outlet 10h may be formed on the housing 10, may be located on the front cover 5, may be located on the rear cover 6, and the position of the outlet 10h is not particularly limited. ..

The louver 11 is rotatably attached to the housing 10. Specifically, the louver 11 is rotatably attached to the housing 10 about a rotation axis (not shown). The rotation axis of the louver 11 is, for example, substantially parallel to the horizontal direction (for example, the Y axis). The louver 11 guides the airflow moving inside the housing 10 and branches it into a front airflow F31 moving on the front cover 5 side and a rear airflow F32 moving on the rear cover 6 side.

In the example of FIG. 2, the front airflow F31 flows out from the outlet 10h toward the front side of the humidity control device 100, and the rear airflow F32 flows out from the outflow port 10h toward the rear side of the humidity control device 100. There is.

Further, the louver 11 adjusts the direction in which the air passing through the inside of the housing 10 flows out at the outlet 10h. That is, the louver 11 adjusts the direction of the front airflow F31 and the direction of the rear airflow F32 flowing out from the outflow port 10h at the outflow port 10h. Specifically, by rotating the louver 11, the direction of the front airflow F31 flowing out from the outflow port 10h and the direction of the rear airflow F32 are adjusted. Further, the louver 11 has a substantially triangular shape, for example, in a cross-sectional view.

Next, the humidity control device 100 will be described in detail with reference to FIGS. 1 to 4. As shown in FIG. 2, the humidity control device 100 further includes a rectifying member 13, an air purifying filter 15, a humidifying section 16, a dehumidifying section 17, a blowing section 20, and a duct 22. FIG. 3 is a view of the blower portion 20 of the humidity control device 100 of the first embodiment as viewed from the front cover 5 side. FIG. 4 is a view of the blower portion 20 of the humidity control device 100 of the first embodiment as viewed from the rear cover 6 side.

The blower unit 20 blows air. The blower unit 20 is, for example, a centrifugal fan. A turbo fan or a high-pressure axial flow fan may be used instead of the blower unit 20.

The ventilation unit 20 of the present embodiment sucks air from the front region 20A and the back region 20B, and blows the air to the outlet 10h. The front area 20A corresponds to an example of the "first suction area". The front area 20A is an area on the front cover 5 side as shown in FIGS. 2 and 3. The back area 20B is an area opposite to the front area 20A. Specifically, the back surface region 20B is a region on the rear cover 6 side as shown in FIGS. 2 and 4. The back surface region 20B corresponds to an example of the “second suction region”. The blower portion 20 of the present embodiment is, for example, a double suction type sirocco fan.

The blower portion 20 includes a casing 21, a duct 22, a motor 201, blades 203, and a fixing member 221.

As shown in FIG. 2, the casing 21 accommodates the blade 203 and the motor 201. The casing 21 has a box shape. The casing 21 has a front opening 21a, a rear opening 21b, and a discharge port 21c.

As shown in FIG. 3, the front opening 21a is a suction port on the front cover 5 side. For example, the front opening 21a is a suction port in which the humidifying portion 16 sucks in the humidified air. The front opening 21a corresponds to the front area 20A. The front opening 21a corresponds to an example of the "first opening".

As shown in FIG. 4, the rear opening 21b is a suction port on the rear cover 6 side. For example, the rear opening 21b is a suction port where the dehumidifying unit 17 sucks in the dehumidified air. The rear opening 21b corresponds to the back area 20B. The rear opening 21b corresponds to an example of the "second opening".

Humidity-controlled air is discharged from the discharge port 21c. Specifically, the discharge port 21c discharges the air humidified by the humidifying unit 16. Specifically, the discharge port 21c discharges the air dehumidified by the dehumidifying unit 17.

The motor 201 rotates the blade 203. The motor 201 corresponds to an example of a "fan drive unit".

The blade 203 rotates to generate wind. The blade 203 rotates about the drive axis AX of the motor 201. The blade 203 rotates by transmitting power from the motor 201, for example. In the case of a double suction type sirocco fan, it is attached to one side surface and the other side surface with respect to the partition plate to which the blade 203 is attached. Further, the blade 203 may be arranged on one side of the partition plate. The back surface region 20B is located on the opposite side of the front surface region 20A with respect to the blade 203. Further, the front region 20A is located on the opposite side of the back region 20B with respect to the blade 203.

In the present embodiment, the blower unit 20 discharges air in the centrifugal direction. Specifically, as the blade 203 rotates, air is sucked into the housing 10 from the inflow port 14. Then, the air sucked from the inflow port 14 moves to generate the first air flow F10, which passes through the air purifying filter 15. Then, the first airflow F10 passes through the humidifying portion 16. Then, the first airflow F10 is sucked from the front region 20A of the front opening 21a. Then, the air in the first airflow F10 is discharged to the duct 22 from the discharge port 21c as the third airflow F30.

Further, as the blade 203 rotates, air is sucked into the housing 10 from the inflow port 14. Then, the air sucked from the inflow port 14 moves to generate a second air flow F20, which passes through the air purifying filter 15. Then, the second airflow F20 passes through the dehumidifying unit 17. Then, the second airflow F20 is sucked from the back surface region 20B of the rear opening 21b. Then, the air in the second airflow F20 is discharged to the duct 22 from the discharge port 21c as the third airflow F30.

The duct 22 guides the third airflow F30 generated by the rotation of the blade 203 to the rectifying member 13. The duct 22 constitutes a part of the flow path FP. The duct 22 may be provided with an ion generator that contains ions in the third airflow F30. In this case, the ion generator discharges in the atmosphere to generate ions. The ion generator preferably has a configuration in which positive ions H ⁺ (H ₂ O) m and negative ions O ^2- (H ₂ O) n, each of which has an arbitrary natural number of m and n, are generated. In this case, positive and negative ions adhere to the surface of airborne bacteria and viruses and react to generate active species OH radical (・ OH) and hydrogen peroxide (H ₂ O ₂ ) on the surface for sterilization. It can be effective.

As shown in FIG. 4, the fixing member 221 fixes the blade 203 and the motor 201 to the casing 21.

As shown in FIG. 2, the air purifying filter 15 is, for example, a HEPA (High Efficiency Particulate Air) filter in which a non-woven fabric is formed in a paper shape. However, the type of the air purifying filter 15 is not particularly limited. The air purifying filter 15 purifies the first air flow F10 and the second air flow F20 sucked from the inflow port 14.

The humidifying unit 16 regulates the humidity of the air flowing in from the inflow port 14. In the first embodiment, the humidifying section 16 corresponds to an example of the "first humidity control section". Specifically, the humidifying unit 16 can humidify the air flowing in from the inflow port 14. The humidifying section 16 has a humidifying filter 161 and a tank 162.

The humidifying filter 161 has water absorption and ventilation. That is, the humidifying filter 161 absorbs water from the tank 162 and allows air to pass therethrough. The air is humidified by passing the air through the humidifying filter 161 that has absorbed water. In other words, the humidifying filter 161 functions as a vaporization filter.

The tank 162 contains water for humidification (for example, tap water). The water contained in the tank 162 is supplied to the humidifying filter 161. A part of the humidifying filter 161 is housed inside the tank 162. Further, the humidifying filter 161 is fixed in the tank 162, for example. The first airflow F10 purified by the air purifying filter 15 is humidified by passing through the humidifying filter 161.

The dehumidifying unit 17 regulates the humidity of the air flowing in from the inflow port 14. In the first embodiment, the dehumidifying unit 17 corresponds to an example of the "second humidity control unit". Specifically, the dehumidifying unit 17 can dehumidify the air flowing in from the inflow port 14. The dehumidifying unit 17 includes a cooling unit 171, a heat radiating unit 172, a compression unit (not shown), and an expansion unit (not shown).

The compression unit (not shown) pumps the refrigerant. The compression unit includes a compressor. The expansion portion (not shown) depressurizes the refrigerant. The inflatable portion includes, for example, a capillary tube. A refrigeration cycle is formed inside the housing 10. The refrigeration cycle is a cycle in which a circulation path is formed in which a compression section, a heat dissipation section 172, an expansion section, and a cooling section 171 are connected in a ring shape, and the refrigerant is circulated through the circulation path by the compression section. In the refrigeration cycle, the temperature and pressure of the refrigerant are increased by the operation of the compression unit. The high temperature and high pressure refrigerant is sent to the heat dissipation unit 172. The heat radiating unit 172 cools the refrigerant by dissipating the heat of the refrigerant in the second air flow F20 passing through the heat radiating unit 172. The refrigerant that has passed through the heat radiating section 172 is sent to the expanding section. The expansion unit reduces the pressure of the refrigerant cooled by the heat radiation unit 172 to generate a low-temperature low-pressure refrigerant. The refrigerant that has passed through the expansion unit is sent to the cooling unit 171. The cooling unit 171 is cooled by supplying a low-temperature and low-pressure refrigerant from the expansion unit. The refrigerant that has passed through the cooling unit 171 is sent to the compression unit. In the refrigeration cycle, the refrigerant circulates in the order of the compression unit, the heat radiation unit 172, the expansion unit, and the cooling unit 171 to suppress the temperature rise of the cooling unit 171. In the refrigeration cycle, since the refrigerant whose temperature and pressure have been increased by the compression unit is sent to the heat radiation unit 172, the temperature of the heat radiation unit 172 rises.

The cooling unit 171 cools the second airflow F20 passing through the cooling unit 171. The cooling unit 171 includes an evaporator. The cooling unit 171 cools the air passing through the cooling unit 171 to condense the moisture contained in the air. As a result, the second airflow F20 is dehumidified.

The heat radiating unit 172 is arranged so as to face the cooling unit 171. The heat dissipation unit 172 cools the cooling unit 171 by cooling the refrigerant in the refrigeration cycle. The heat dissipation unit 172 includes a capacitor. The heat radiating unit 172 cools the refrigerant by radiating the heat of the refrigerant into the air passing through the heat radiating unit 172. The refrigerant that has passed through the heat radiating section 172 is sent to the expanding section. The expansion unit reduces the pressure of the refrigerant cooled by the heat radiation unit 172 to generate a low-temperature low-pressure refrigerant. The heat radiating unit 172 exchanges heat between the second airflow F20 that has passed through the cooling unit 171 and the refrigerant. As a result, the second airflow F20 that has passed through the cooling unit 171 receives heat from the refrigerant, and the temperature of the second airflow F20 rises.

The rectifying member 13 rectifies the third airflow F30 discharged from the discharge port 21c. The rectifying member 13 is located upstream of the air flow from the outlet 10h in the flow path FP. Specifically, the rectifying member 13 is located at the upstream end of the air flow in the flow path FP. The rectifying member 13 rectifies the third airflow F30 according to the shape of the rectifying member 13. The rectifying member 13 reduces, for example, the swirling flow, knitting flow, and / or contracted flow of the third airflow F30 passing through the flow path FP.

(Operation of humidification function)
Next, the operation of the humidifying function of the humidity control device 100 will be described. During the humidifying operation of the humidity control device 100, water is contained in the tank 162. In addition, the refrigeration cycle has stopped operating. At this time, when the blade 203 rotates, air is sucked into the inside of the housing 10 from the inflow port 14 to generate a first air flow F10, and the first air flow F10 passes through the air purifying filter 15.

Next, the first airflow F10 that has passed through the air purifying filter 15 passes through the humidifying filter 161 and is humidified. Further, the first airflow F10 that has passed through the humidifying filter 161 is sucked into the front opening 21a. The first airflow F10 sucked into the front opening 21a passes through the blower portion 20, the discharge port 21c, and the rectifying member 13, and flows out from the outlet 10h to the outside of the humidity control device 100.

(Operation of dehumidifying function)
Next, the operation of the dehumidifying function of the humidity control device 100 will be described. During the dehumidifying operation of the humidity control device 100, the tank 162 does not contain water. Also, the refrigeration cycle is operated. At this time, when the blade 203 rotates, air is sucked into the inside of the housing 10 from the inflow port 14 to generate a second airflow F20, and the second airflow F20 passes through the air purifying filter 15.

Next, the second airflow F20 that has passed through the air purifying filter 15 passes through the cooling unit 171 and the heat radiating unit 172 to be dehumidified. The second airflow F20 that has passed through the cooling unit 171 and the heat radiating unit 172 is sucked into the rear opening 21b, passes through the air blowing unit 20 and the exhaust port 21c, and flows out from the outlet 10h to the outside of the humidity control device 100.

Next, the humidity control device 100 will be described in more detail with reference to FIGS. 2 to 5. FIG. 5 is another view of the blower portion 20 of the humidity control device 100 of the first embodiment as viewed from the rear cover 6 side. As shown in FIG. 5, the humidity control device 100 further includes a shutter unit 40.

The shutter unit 40 changes the area of the back surface area 20B. Specifically, the shutter portion 40 changes the area of the back surface region 20B by closing a part of the rear opening 21b. The shutter unit 40 changes the area where air can actually be sucked by changing the area of the back surface area 20B. Further, air is not sucked from the portion where the shutter portion 40 is located. In other words, the amount of air sucked from the side of the back area 20B is changed according to the area of the back area 20B. For example, as the area of the back surface region 20B becomes larger, the resistance when the blower portion 20 sucks air becomes smaller, and the amount of air sucked from the back surface region 20B side increases. Further, for example, as the area of the back surface region 20B becomes smaller, the resistance when the blower portion 20 sucks air increases, and the amount of air sucked from the back surface region 20B side decreases.

As described with reference to FIGS. 1 to 5, the humidity control device 100 includes a housing 10, a humidification section 16 which is a first humidity control section, a blower section 20, and a shutter section 40. According to the present embodiment, in the back area 20B, the shutter portion 40 becomes a resistance when sucking air, and the amount of air sucked from the back area 20B is reduced. Then, the air blowing unit 20 sucks the air regulated by the humidifying unit 16 from the front region 20A and blows the air to the outlet 10h. Therefore, the amount of air sucked from the front region 20A can be larger than the amount of air sucked from the back region 20B. As a result, the amount of air toward the humidifying portion 16 can be changed. Therefore, it is possible to efficiently humidify the air and increase the humidified air.

Specifically, by making the amount of air sucked from the front region 20A larger than the amount of air sucked from the back region 20B, the amount of humidified air increases. As a result, the proportion of humidified air can be increased in the air flowing out from the outlet 10h.

As shown in FIGS. 4 and 5, the fixing member 221 closes a part of the rear opening 21b. The shutter unit 40 includes a shutter 42, a shutter drive unit 41, and a drive transmission unit (not shown). In FIG. 4, the shutter 42 is arranged so as to overlap the fixing member 221.

As shown in FIG. 4, the shutter 42 adjusts the area of the back surface area 20B. Specifically, the shutter 42 is arranged on the rear opening 21b by the shutter driving unit 41 to adjust the area of the back surface region 20B.

The shutter drive unit 41 moves the shutter 42. The shutter drive unit 41 is fixed to the fixing member 221. The shutter drive unit 41 is a motor. The shutter drive unit 41 transmits the drive force to the drive transmission unit, and the drive force is transmitted from the drive transmission unit to the shutter 42. Therefore, the shutter drive unit 41 can move the shutter 42.

As shown in FIGS. 4 and 5, the shutter drive unit 41 moves the shutter 42 in the circumferential direction of the drive axis AX of the motor 201. Specifically, the shutter drive unit 41 moves the shutter 42 in the circumferential direction of the drive axis AX, and arranges the shutter 42 on the rear opening 21b. That is, the shutter 42 can adjust the area of the back area 20B by closing a part of the rear opening 21b. Therefore, the shutter 42 becomes a resistance when air is sucked from the back surface region 20B. Therefore, the amount of air sucked from the back region 20B can be adjusted, and the amount of air sucked from the front region 20A and the amount of air sucked from the back region 20B can be different. As a result, the amount of air toward the humidifying portion 16 can be increased so that the humidified air can flow out from the outlet 10h.

Subsequently, the blower unit 20 will be described in more detail with reference to FIGS. 4 and 5. The fixing member 221 has a main body portion 222 and a mounting portion 223.

The main body 222 supports the motor 201.

The mounting portion 223 mounts the main body portion 222 on the casing 21. The mounting portion 223 extends from the main body portion 222 toward the casing 21.

Further, as shown in FIG. 4, the mounting portion 223 is larger than the shutter 42. In other words, the shutter 42 is smaller than the mounting portion 223. Therefore, when the mounting portion 223 and the shutter 42 are arranged so as to overlap each other, the shutter 42 does not protrude from the mounting portion 223. As a result, it is possible to suppress the shutter 42 from becoming a resistance when sucking air.

Further, the shutter drive unit 41 moves the shutter 42 to the first position STA and the second position STB. As shown in FIG. 5, the first position STA indicates the position when the shutter 42 adjusts the back area 20B. In the first position STA, the shutter 42 is in a state where the mounting portion 223 and a part of the shutter 42 overlap each other.

As shown in FIG. 4, the second position STB shows a different position from the first position STA. Specifically, the second position STB indicates a position when the shutter 42 does not adjust the back area 20B. In the second position STB, the shutter 42 is in a state where the mounting portion 223 and the entire shutter 42 are overlapped with each other. Therefore, the area of the front area 20A and the area of the back area 20B can be different. As a result, the amount of air sucked from the front region 20A and the amount of air sucked from the back region 20B can be made different.

For example, when the area of the back surface region 20B is smaller than the area of the front surface region 20A, the shutter unit 40 is controlled so that the state of the rear opening 21b shown in FIG. 4 changes to the state of the rear opening 21b shown in FIG. Specifically, as shown in FIG. 4, the control unit 80 controls the shutter drive unit 41 so that the shutter drive unit 41 moves the shutter 42 to the first position STA. Therefore, the area of the back area 20B is smaller than the area of the front area 20A. That is, the amount of air sucked from the front region 20A is smaller than the amount of air sucked from the back region 20B.

Further, as shown in FIGS. 4 and 5, the fixing member 221 divides the rear opening 21b into three parts. In other words, the fixing member 221 divides the back surface region 20B into three parts. The fixing member 221 has a plurality of mounting portions 223.

Each of the plurality of mounting portions 223 extends from the main body portion 222 toward the casing 21. Each of the plurality of mounting portions 223 is mounted on the casing 21. Each of the plurality of mounting portions 223 covers a part of the rear opening 21b. Specifically, the plurality of mounting portions 223 are three mounting portions 223.

Further, the shutter unit 40 has a plurality of shutters 42. Specifically, the shutter unit 40 has three shutters 42. Each of the three shutters 42 is arranged so as to overlap the fixing member 221. Specifically, each of the three shutters 42 is arranged so as to overlap the mounting portion 223.

Each of the three shutters 42 adjusts the area of one of the three separated back areas 20B. The shutter drive unit 41 may move one of the three shutters 42, the shutter 42. Further, the shutter drive unit 41 may simultaneously move two shutters 42 out of the three shutters 42. Further, the shutter drive unit 41 may move the three shutters 42 at the same time.

Subsequently, the humidity control device 100 will be described in more detail with reference to FIGS. 1 to 5. As shown in FIG. 2, the humidity control device 100 further includes a detection unit 30, a storage unit 70, and a control unit 80.

The detection unit 30 detects the humidity of the environment in which the humidity control device 100 is installed. Specifically, the detection unit 30 detects the humidity of the room in which the humidity control device 100 is installed. The detection unit 30 detects the humidity and outputs a detection signal indicating the humidity to the control unit 80. The detection unit 30 is arranged in, for example, the housing 10.

The storage unit 70 stores data and computer programs. The storage unit 70 is housed in the housing 10. For example, the storage unit 70 temporarily stores the data required for each process of the control unit 80, or stores the setting data for the humidifying unit 16. The storage unit 70 includes a storage device (main storage device and auxiliary storage device), and includes, for example, a memory and a hard disk drive. The storage unit 70 may include removable media.

The control unit 80 is housed in the housing 10. The control unit 80 includes a processor such as a CPU (Central Processing Unit) or an ASIC (Application Specific Integrated Circuit), and a storage device. For example, the control unit 80 receives various signals from each element of the humidity control device 100, and controls each element of the humidity control device 100 based on the received signals. Specifically, the control unit 80 controls each element of the humidity control device 100 such as the humidification unit 16, the dehumidification unit 17, the blower unit 20, the detection unit 30, and the storage unit 70.

Further, the control unit 80 controls the shutter unit 40. Specifically, when the humidifying unit 16 humidifies the air, the control unit 80 shutters so that the area of the back surface area 20B is smaller than the area of the back surface area 20B when the dehumidifying unit 17 dehumidifies the air. The unit 40 is controlled. Therefore, the amount of air sucked from the back area 20B can be changed according to the area of the back area 20B. As a result, it is possible to prevent the humidified air and the unhumidified air from being excessively mixed inside the housing 10.

Further, when the humidifying unit 16 humidifies the air, the control unit 80 controls the shutter unit 40 so that the area of the back surface region 20B is smaller than the area of the front surface region 20A. Therefore, the amount of air sucked from the front region 20A is larger than the amount of air sucked from the back region 20B. That is, the balance of the air volume is changed, and the amount of air toward the humidifying portion 16 can be increased. Therefore, since more air passes through the humidifying filter 161 of the humidifying section 16, the air can be further humidified.

Further, when the dehumidifying unit 17 dehumidifies the air, the control unit 80 controls the shutter unit 40 so as to prohibit changing the area of the back surface region 20B. The dehumidifying unit 17 dehumidifies the air sucked from the back surface region 20B. Therefore, the humidity of the environment in which the humidity control device 100 is installed can be adjusted by combining the humidification of air and the dehumidification of air. As a result, the humidity of the environment in which the humidity control device 100 is installed can be easily changed to the humidity desired by the user.

When the dehumidifying unit 17 dehumidifies the air, the control unit 80 may control the shutter unit 40 so that the area of the back surface region 20B is larger than the area of the front surface region 20A. Therefore, depending on the size of the area, the amount of air passing through the front area 20A is smaller than the amount of air passing through the back area 20B. That is, the balance of the air volume can be changed to increase the air volume toward the dehumidifying unit 17. As a result, it becomes easy to dehumidify the air.

Further, the control unit 80 determines whether or not the humidity is the target humidity. Specifically, the control unit 80 determines whether or not the humidity of the environment in which the humidity control device 100 is arranged is lower than the target humidity based on the detection result of the detection unit 30. Then, when the humidity of the environment is lower than the target humidity, the control unit 80 controls the shutter unit 40 so that the shutter unit 40 makes the area of the back area 20B smaller than the area of the front area 20A. Therefore, the amount of air toward the dehumidifying unit 17 can be reduced. That is, the amount of air toward the humidifying portion 16 increases, and the amount of air passing through the humidifying filter 161 increases. As a result, the humidification efficiency of air is improved.

Further, the control unit 80 controls the shutter unit 40 so that the shutter unit 40 makes the area of the back area 20B larger than the area of the front area 20A when the humidity of the environment is not lower than the target humidity. Therefore, the amount of air toward the dehumidifying portion 17 can be increased. That is, the amount of air toward the dehumidifying unit 17 increases, and the amount of air passing through the cooling unit 171 increases. As a result, the dehumidifying efficiency of air is improved.

Next, the process executed by the control unit 80 will be described with reference to FIG. FIG. 6 is a flowchart of the process executed by the control unit 80. As shown in FIG. 6, the process executed by the control unit 80 includes steps S101 to S105.

In step S101, the control unit 80 controls the humidifying unit 16 so that the humidifying unit 16 starts humidity control. Specifically, the control unit 80 controls the humidifying unit 16 so that the humidifying unit 16 humidifies the air. The process proceeds to step S102.

In step S102, the control unit 80 acquires the detection result of the detection unit 30. The process proceeds to step S103.

In step S103, the control unit 80 determines whether or not the humidity of the environment is lower than the target humidity by installing the humidity control device 100 based on the detection result of the detection unit 30. If the humidity is not lower than the target humidity (No in step S103), the process proceeds to step S105. If the humidity is lower than the target humidity (Yes in step S103), the process proceeds to step S104.

In the case of Yes in step S103, in step S104, the control unit 80 controls the shutter unit 40 so that the shutter unit 40 changes the area of the back surface area 20B. Specifically, when the humidifying unit 16 humidifies the air, the control unit 80 shutters so that the area of the back surface area 20B is smaller than the area of the back surface area 20B when the dehumidifying unit 17 dehumidifies the air. The unit 40 is controlled. The process ends.

If No in step S103, in step S105, the control unit 80 controls the shutter unit 40 so that the shutter unit 40 makes the area of the back area 20B larger than the area of the front area 20A. The process ends.

[Embodiment 2]
Next, the humidity control device 100 according to the second embodiment of the present invention will be described with reference to FIGS. 1 to 5 and 7. The humidity control device 100 according to the second embodiment is different from the humidity control device 100 according to the first embodiment in that the control unit 80 makes a determination based on the rate of increase in humidity. Hereinafter, the second embodiment will mainly explain the differences from the first embodiment.

The control unit 80 of the second embodiment determines whether or not the rate of increase in humidity is a predetermined rate of increase. Specifically, the control unit 80 determines whether or not the rate of increase in humidity in the environment in which the humidity control device 100 is arranged is lower than the predetermined rate of increase, based on the detection result of the detection unit 30. Then, the control unit 80 controls the shutter unit 40 so that when the rate of increase in humidity is lower than the predetermined rate of increase, the shutter unit 40 makes the area of the back area 20B smaller than the area of the front area 20A. Therefore, the amount of air toward the dehumidifying unit 17 can be reduced. That is, the amount of air toward the humidifying portion 16 increases, and the amount of air passing through the humidifying filter 161 increases. As a result, the humidification efficiency of air is improved.

Further, the control unit 80 controls the shutter unit 40 so that the shutter unit 40 makes the area of the back area 20B larger than the area of the front area 20A when the rate of increase in the humidity of the environment is not lower than the predetermined rate of increase. do. Therefore, the amount of air toward the dehumidifying portion 17 can be increased. That is, the amount of air toward the dehumidifying unit 17 increases, and the amount of air passing through the cooling unit 171 increases. As a result, the dehumidifying efficiency of air is improved.

Next, the process executed by the control unit 80 will be described with reference to FIG. 7. FIG. 7 is a flowchart of the process executed by the control unit 80 of the humidity control device 100 of the second embodiment. As shown in FIG. 7, the process executed by the control unit 80 includes steps S201 to S205. Since step S201, step S202, step S204, and step S205 correspond to step S101, step S102, step S104, and step S105 shown in FIG. 6, description thereof will be omitted.

After step S202, in step S203, the control unit 80 determines whether or not the rate of increase in humidity in the environment in which the humidity control device 100 is arranged is lower than the predetermined rate of increase, based on the detection result of the detection unit 30. do. If the rate of increase in humidity is not lower than the predetermined rate of increase (No in step S203), the process proceeds to step S205. If the rate of increase in humidity is lower than the rate of increase in humidity (Yes in step S203), the process proceeds to step S204.

[Embodiment 3]
Next, the humidity control device 100 according to the third embodiment of the present invention will be described with reference to FIGS. 1 and 8. The humidity control device 100 according to the third embodiment is different from the humidity control device 100 according to the first embodiment in that the "first humidity control unit" dehumidifies and the "second humidity control unit" humidifies. Hereinafter, the third embodiment will mainly explain the differences from the first embodiment.

FIG. 8 is a diagram showing a cross section of the humidity control device 100 of the third embodiment. As shown in FIGS. 1 and 8, the humidity control device 100 of the third embodiment includes an operation unit 8, a housing 10, a louver 11, a rectifying member 13, an air cleaning filter 15, and a humidifying unit 16. It includes a dehumidifying unit 17, a ventilation unit 20, a duct 22, a shutter unit 40, a detection unit 30, a storage unit 70, and a control unit 80. The humidifying section 16 of the third embodiment corresponds to an example of the “second humidity control section”. The dehumidifying section 17 of the third embodiment corresponds to an example of the "first humidity control section".

The operation unit 8 receives an instruction from the outside. The louver 11 guides the airflow moving inside the housing 10. The rectifying member 13 rectifies the airflow discharged from the discharge port 21c. The air purifying filter 15 purifies the first air flow F10 and the second air flow F20 sucked from the inflow port 14. The duct 22 guides the airflow generated by the rotation of the blade 203 to the rectifying member 13. The detection unit 30 detects the humidity of the room in which the humidity control device 100 is installed. The storage unit 70 stores data and computer programs. The control unit 80 controls each element of the humidity control device 100.

The housing 10 accommodates each configuration of the humidity control device 100. The housing 10 includes a front cover 5, a rear cover 6, a pair of side plates 7, and a handle 9. As shown in FIG. 8, the housing 10 has an inlet 14 and an outlet 10h.

The blower unit 20 sucks air from the front region 20A and the back region 20B, and blows the air to the outlet 10h. The front area 20A of the third embodiment corresponds to an example of the “second suction area”. The back surface region 20B of the third embodiment corresponds to an example of the “first suction region”. The blower portion 20 includes a casing 21, a duct 22, a motor 201, blades 203, and a fixing member 221.

As shown in FIG. 8, the casing 21 accommodates the blade 203 and the motor 201. The casing 21 has a front opening 21a, a rear opening 21b, and a discharge port 21c. The front opening 21a is a suction port where the humidifying portion 16 sucks in the humidified air. The rear opening 21b is a suction port where the dehumidifying portion 17 sucks in the dehumidified air. Humidity-controlled air is discharged from the discharge port 21c.

The motor 201 rotates the blade 203. The blade 203 rotates to generate wind. The fixing member 221 fixes the blade 203 and the motor 201 to the casing 21.

The humidifying unit 16 regulates the humidity of the air flowing in from the inflow port 14. Specifically, the humidifying unit 16 can humidify the air flowing in from the inflow port 14. The humidifying section 16 has a humidifying filter 161 and a tank 162.

The dehumidifying unit 17 regulates the humidity of the air flowing in from the inflow port 14. Specifically, the dehumidifying unit 17 can dehumidify the air flowing in from the inflow port 14. The dehumidifying unit 17 includes a cooling unit 171, a heat radiating unit 172, a compression unit (not shown), and an expansion unit (not shown). A refrigeration cycle is formed inside the housing 10.

The shutter unit 40 of the third embodiment changes the area of the front area 20A. The shutter portion 40 serves as a resistance when the blower portion 20 sucks air from the front region 20A. That is, the shutter portion 40 reduces the amount of air sucked from the front region 20A. In other words, the amount of air sucked from the side of the front area 20A is changed according to the area of the front area 20A. For example, as the area of the front region 20A becomes larger, the resistance when the blower portion 20 sucks air becomes smaller, and the amount of air sucked from the side of the front region 20A increases. Further, for example, as the area of the front region 20A becomes smaller, the resistance when the blower portion 20 sucks air increases, and the amount of air sucked from the side of the front region 20A decreases.

Then, the air blowing unit 20 sucks the air regulated by the dehumidifying unit 17 from the back surface region 20B, and blows the air to the outlet 10h. In the front region 20A, the shutter portion 40 becomes a resistance when sucking air, and the amount of air sucked from the front region 20A decreases. Therefore, the amount of air sucked from the back region 20B can be larger than the amount of air sucked from the front region 20A. As a result, the amount of air toward the dehumidifying unit 17 can be changed. Therefore, it is possible to efficiently dehumidify the air and increase the dehumidified air.

Specifically, the amount of dehumidified air is increased by making the amount of air sucked from the back region 20B larger than the amount of air sucked from the front region 20A. As a result, the proportion of dehumidified air in the air flowing out from the outlet 10h can be increased.

In the third embodiment, there is only one shutter unit 40 that changes the area of the front area 20A, but the present invention is not limited to this. For example, it may further have a shutter portion 40 that changes the area of the back surface region 20B of the first embodiment.

[Embodiment 4]
Next, the humidity control device 100 according to the fourth embodiment of the present invention will be described with reference to FIGS. 1, 2, 6, 7, and 9. In the humidity control device 100 according to the fourth embodiment, the shape of the shutter portion 40 is different from the shutter portion 40 of the humidity control device 100 according to the first embodiment. Hereinafter, the fourth embodiment mainly describes the differences from the first embodiment. FIG. 9 is a diagram showing the shutter unit 40 of the fourth embodiment. FIG. 9 includes a first position STA of the shutter 42 and a second position STB of the shutter 42.

The shutter portion 40 of the fourth embodiment changes the area of the back surface region 20B. Specifically, the shutter portion 40 changes the area of the back surface region 20B by moving from the outer edge side of the rear opening 21b toward the drive axis AX of the motor 201. The shutter unit 40 of the fourth embodiment changes the area of the back surface region 20B by, for example, a known aperture mechanism of a camera. That is, the amount of air sucked from the side of the back surface region 20B is changed according to the area of the back surface region 20B. For example, as the area of the back surface region 20B increases, the amount of air sucked from the back surface region 20B side increases. Further, for example, as the area of the back surface region 20B becomes smaller, the amount of air sucked from the back surface region 20B side decreases.

The shutter unit 40 includes a plurality of shutters 42, a shutter drive unit 41, and a drive transmission unit (not shown).

The plurality of shutters 42 are arranged at the outer edge portion of the rear opening 21b. Each of the plurality of shutters 42 is moved from the outer edge of the rear opening 21b toward the drive axis AX by the shutter drive unit 41. Therefore, the area of the back surface region 20B can be adjusted by the plurality of shutters 42.

The shutter drive unit 41 moves a plurality of shutters 42. The shutter drive unit 41 is fixed to the fixing member 221. The shutter drive unit 41 is a motor. The shutter drive unit 41 transmits the drive force to the drive transmission unit, and the drive force is transmitted from the drive transmission unit to the plurality of shutters 42. Therefore, the shutter drive unit 41 can move a plurality of shutters 42.

Further, the shutter drive unit 41 of the fourth embodiment moves the shutter 42 to the first position STA and the second position STB. As shown in FIG. 9, the first position STA indicates the position when the shutter 42 adjusts the back area 20B. In the first position STA, the shutter 42 is in a state where the mounting portion 223 and a part of the shutter 42 overlap each other. Further, as shown in FIG. 9, the second position STB indicates a position different from that of the first position STA. Specifically, the second position STB indicates a position when the shutter 42 does not adjust the back area 20B. Therefore, in the shutter portion 40 of the fourth embodiment, the area of the front area 20A and the area of the back area 20B can be different. As a result, the amount of air sucked from the front region 20A and the amount of air sucked from the back region 20B can be made different.

[Embodiment 5]
Next, the humidity control device 100 according to the fifth embodiment of the present invention will be described with reference to FIGS. 1, 2, 6, 7, and 10. In the humidity control device 100 according to the fifth embodiment, the shape of the shutter portion 40 is different from the shutter portion 40 of the humidity control device 100 according to the first embodiment. Hereinafter, the fifth embodiment will mainly explain the differences from the first embodiment. FIG. 10 is a diagram showing the shutter unit 40 of the fifth embodiment. FIG. 10 includes a second position STB of the shutter 42 and a first position STA of the shutter 42.

The shutter portion 40 of the fifth embodiment changes the area of the back surface region 20B. The shutter portion 40 of the fifth embodiment has a sheet shape. The shutter portion 40 is arranged outside the casing 21. The shutter portion 40 changes the area of the back surface region 20B of the rear opening 21b by covering a part of the rear opening 21b. That is, the amount of air sucked from the side of the back surface region 20B is changed according to the area of the back surface region 20B. For example, as the area of the back surface region 20B increases, the amount of air sucked from the back surface region 20B side increases. Further, for example, as the area of the back surface region 20B becomes smaller, the amount of air sucked from the back surface region 20B side decreases.

The shutter unit 40 includes a shutter 42, a shutter drive unit 41, and a drive transmission unit (not shown).

The shutter 42 has a sheet shape. The shutter 42 includes a plurality of ventilation portions 421 and a non-ventilation portion 422. Wind passes through the plurality of ventilation portions 421. The plurality of ventilation portions 421 have openings. Wind does not pass through the non-ventilation portion 422.

The shutter drive unit 41 moves the shutter 42. The shutter drive unit 41 is a motor. The shutter drive unit 41 of the fifth embodiment moves the shutter 42 to the first position STA and the second position STB.

For example, the shutter drive unit 41 rotates in the first rotation direction to move the sheet-shaped shutter 42 to the first position STA. As shown in FIG. 10, the first position STA indicates the position when the shutter 42 adjusts the back area 20B. Specifically, when the shutter drive unit 41 rotates in the first rotation direction, the sheet-shaped shutter 42 is in a hanging state, and the shutter 42 moves to the first position STA. That is, when the sheet-shaped shutter 42 hangs down, as shown in FIG. 10, the shutter 42 and the rear opening 21b overlap each other.

In the fifth embodiment, the wind passes through the ventilation portion 421 in a state where the shutter 42 and the rear opening 21b overlap each other. That is, the area of the ventilation portion 421 corresponds to the area of the back surface region 20B. In other words, the area of the back surface area 20B is adjusted by the size of the ventilation portion 421.

Therefore, in the shutter portion 40 of the fifth embodiment, the area of the front area 20A and the area of the back area 20B can be different. As a result, the amount of air sucked from the front region 20A and the amount of air sucked from the back region 20B can be made different.

Further, for example, the shutter drive unit 41 rotates in the second rotation direction to move the sheet-shaped shutter 42 to the second position STB. The second position STB indicates a position when the shutter 42 does not adjust the back area 20B. Specifically, the shutter drive unit 41 rotates in the second rotation direction to wind up the sheet-shaped shutter 42 and move the shutter 42 to the second position STB. That is, by winding up the sheet-shaped shutter 42, the shutter 42 and the rear opening 21b do not overlap with each other.

[Modification 1]
Next, the humidity control device 100 according to the first modification of the fifth embodiment of the present invention will be described with reference to FIGS. 1, 2, 6, 7, and 11. In the humidity control device 100 according to the first modification of the fifth embodiment, the shape of the shutter portion 40 is different from the shutter portion 40 of the humidity control device 100 according to the fifth embodiment. Hereinafter, the first modification of the fifth embodiment will mainly explain the differences from the fifth embodiment. FIG. 11 is a diagram showing the shutter portion 40 of the modified example 1.

The shutter portion 40 of the modification 1 changes the area of the back surface region 20B. The shutter portion 40 of the fifth embodiment has a sheet shape. The shutter portion 40 is arranged outside the casing 21. The shutter portion 40 changes the area of the back surface region 20B of the rear opening 21b by covering a part of the rear opening 21b. That is, the amount of air sucked from the side of the back surface region 20B is changed according to the area of the back surface region 20B. For example, as the area of the back surface region 20B increases, the amount of air sucked from the back surface region 20B side increases. Further, for example, as the area of the back surface region 20B becomes smaller, the amount of air sucked from the back surface region 20B side decreases.

The shutter unit 40 includes a shutter 42, a shutter drive unit 41, and a drive transmission unit (not shown).

The shutter 42 is arranged so as to overlap the rear opening 21b. The shutter 42 has a sheet shape. The shutter 42 includes a ventilation portion 421 and a non-ventilation portion 422. Wind passes through the ventilation section 421. The ventilation portion 421 has an opening. Wind does not pass through the non-ventilation portion 422.

The shutter drive unit 41 moves the shutter 42. The shutter drive unit 41 is a motor. The shutter drive unit 41 includes a first shutter drive unit 41A and a second shutter drive unit 41B.

The first shutter drive unit 41A winds up the shutter 42 by rotating in the first rotation direction. The first shutter drive unit 41A is arranged closer to the operation unit 8 than the second shutter drive unit 41B. The first shutter drive unit 41A of the first modification winds the shutter 42 by rotating in the first rotation direction, and moves the shutter 42.

For example, the first shutter drive unit 41A rotates in the first rotation direction to move the non-ventilation unit 422 of the sheet-shaped shutter 42. Specifically, the first shutter drive unit 41A rotates in the first rotation direction to wind up the sheet-shaped shutter 42, and the non-ventilation portion 422 of the shutter 42 overlaps with the rear opening 21b. That is, it is possible to suppress the inhalation of air from the back surface region 20B.

For example, the first shutter drive unit 41A rotates in the first rotation direction to move the ventilation unit 421 of the sheet-shaped shutter 42. Specifically, the first shutter drive unit 41A rotates in the first rotation direction to wind up the sheet-shaped shutter 42, and the ventilation portion 421 of the shutter 42 overlaps with the rear opening 21b. That is, the amount of air sucked from the back surface region 20B can be reduced.

When the first shutter drive unit 41A rotates in the first rotation direction to wind up the sheet-shaped shutter 42, the shutter 42 wound up by the second shutter drive unit 41B is pulled out.

The second shutter drive unit 41B winds up the shutter 42 by rotating in the second rotation direction. The second shutter drive unit 41B is arranged on the floor side of the first shutter drive unit 41A. The second shutter drive unit 41B of the first modification winds the shutter 42 by rotating in the second rotation direction, and moves the shutter 42.

For example, the second shutter drive unit 41B rotates in the second rotation direction to move the non-ventilation unit 422 of the sheet-shaped shutter 42. Specifically, the second shutter drive unit 41B rotates in the second rotation direction to wind up the sheet-shaped shutter 42, and the non-ventilation portion 422 of the shutter 42 overlaps with the rear opening 21b. That is, it is possible to suppress the inhalation of air from the back surface region 20B.

For example, the second shutter drive unit 41B rotates in the second rotation direction to move the ventilation unit 421 of the sheet-shaped shutter 42. Specifically, the second shutter drive unit 41B rotates in the second rotation direction to wind up the sheet-shaped shutter 42, and the ventilation portion 421 of the shutter 42 overlaps with the rear opening 21b. That is, the amount of air sucked from the back surface region 20B can be reduced.

When the second shutter drive unit 41B rotates in the second rotation direction to wind up the sheet-shaped shutter 42, the shutter 42 wound up by the first shutter drive unit 41A is pulled out.

Therefore, in the shutter portion 40 of the modification 1, the area of the front area 20A and the area of the back area 20B can be different. As a result, the amount of air sucked from the front region 20A and the amount of air sucked from the back region 20B can be made different.

[Modification 2]
Next, the humidity control device 100 according to the second modification of the fifth embodiment of the present invention will be described with reference to FIGS. 1, 2, 6, 7, and 12. In the humidity control device 100 according to the second modification of the fifth embodiment, the shape of the shutter portion 40 is different from the shutter portion 40 of the humidity control device 100 according to the fifth embodiment. Hereinafter, the second modification of the fifth embodiment will mainly explain the differences from the fifth embodiment. FIG. 12 is a diagram showing the shutter 42 of the modified example 2.

The shutter 42 of the second modification is arranged so as to overlap the rear opening 21b. The shutter 42 has a sheet shape. The shutter 42 includes a plurality of ventilation portions 421 and a non-ventilation portion 422. Wind passes through the plurality of ventilation portions 421. The plurality of ventilation portions 421 are arranged side by side. The plurality of ventilation portions 421 have openings. The shape of the opening is, for example, a rectangle. The shape of the opening is not limited to a rectangle, and any wind may pass through it. Wind does not pass through the non-ventilation portion 422.

The shutter drive unit 41 moves the shutter 42. For example, the shutter drive unit 41 rotates in the first rotation direction to move the non-ventilation unit 422 of the sheet-shaped shutter 42. Specifically, the shutter drive unit 41 rotates in the first rotation direction to wind up the sheet-shaped shutter 42, and the non-ventilation portion 422 of the shutter 42 overlaps with the rear opening 21b. That is, it is possible to suppress the inhalation of air from the back surface region 20B.

Further, for example, the shutter drive unit 41 rotates in the first rotation direction to move the ventilation unit 421 of the sheet-shaped shutter 42. Specifically, the shutter drive unit 41 rotates in the first rotation direction to wind up the sheet-shaped shutter 42, and the ventilation portion 421 of the shutter 42 overlaps with the rear opening 21b. That is, the amount of air sucked from the back surface region 20B can be reduced.

Therefore, in the shutter portion 40 of the modification 2, the area of the front area 20A and the area of the back area 20B can be different. As a result, the amount of air sucked from the front region 20A and the amount of air sucked from the back region 20B can be made different.

The embodiments of the present invention have been described above with reference to the drawings. However, the present invention is not limited to the above embodiment, and can be implemented in various embodiments without departing from the gist thereof.
