The heater 6, the moisture releasing portion 7a, the cooling portion 8, the moisture absorbing portion 7b, and the heat radiating portion 9 are arranged in this order. Therefore, the air supplied from the outside of the casing 1 to the first air passage F1 flows in the order of the heater 6, the moisture releasing portion 7a, the cooling portion 8, the moisture absorbing portion 7b, and the heat radiating portion 9, and then the outside of the casing 1. Is discharged to.

Next, the operation of the dehumidifier 100 will be described with reference to FIGS. 2 to 5. FIG. 5 is a diagram showing the flow of air through the first air passage F1.

As shown in FIGS. 2 to 5, the air outside the casing 1 flows into the inside of the casing 1 through the first suction port 3a, and then the heater 6, the moisture releasing portion 7a, the cooling portion 8, and the moisture absorbing portion 7b. , And the heat radiating part 9 in this order, and the air is discharged from the air outlet 2 to the outside of the casing 1.

The air that has flowed into the casing 1 through the first suction port 3a is heated by the heater 6. The air heated by the heater 6 is supplied to the moisture releasing portion 7a. Then, the air heated by the heater 6 vaporizes the moisture contained in the zeolite 71 located in the moisture releasing portion 7a. As a result, high humidity air is generated. High humidity air is discharged from the moisture releasing portion 7a.

The high humidity air discharged from the moisture releasing section 7a is cooled by the cooling section 8. As a result, condensation is formed. The water generated by dew condensation is discharged to the drainage tank 4 via the water collecting section 10.

The air released from the cooling unit 8 is supplied to the moisture absorbing unit 7b. The air supplied to the moisture absorbing portion 7b is dehumidified by the zeolite 71 located in the moisture absorbing portion 7b, and then discharged from the moisture absorbing portion 7b. The dehumidified air released from the moisture absorbing portion 7b is supplied to the heat radiating portion 9 and then discharged from the outlet 2 to the outside of the casing 1.

As described above with reference to FIGS. 2 to 5, in the first air passage F1, the air cooled by the cooling unit 8 is supplied to the heat radiating unit 9. Therefore, since the heat radiating unit 9 can be cooled by the air cooled by the cooling unit 8, the temperature rise of the heat radiating unit 9 can be suppressed. As a result, the refrigerant can be effectively cooled by the heat radiating unit 9 in the refrigeration cycle, so that the cooling efficiency of the cooling unit 8 in the refrigeration cycle can be improved.

Further, by improving the cooling efficiency of the cooling unit 8 by the refrigeration cycle, it is possible to effectively secure the cooled state of the cooling unit 8. When the cold state of the cooling unit 8 is secured, the cooling capacity of the air by the cooling unit 8 can be improved. Therefore, the cooling unit 8 can effectively condense water vapor in the air to generate more water. As a result, it is possible to suppress a decrease in the dehumidifying capacity of the dehumidifier 100.

Further, a heater 6, a moisture releasing portion 7a, a cooling portion 8, and a moisture absorbing portion 7b are arranged on one air passage (first air passage F1). Therefore, the process of dehumidifying by the moisture absorbing section 7b and the process of condensing the moisture dehumidified by the moisture absorbing section 7b by the heater 6, the moisture releasing section 7a, and the cooling section 8 can be performed with a simple device configuration.

Further, when the temperature of the atmosphere of the dehumidifier 100 is sufficiently high, the air can be cooled to the extent that dew condensation occurs by the cooling unit 8 even when the heater 6 is OFF. In this case, from the viewpoint of power saving, the dehumidifier 100 may be operated with the heater 6 turned off. Further, in the first air passage F1, a heat radiating unit 9 is arranged downstream of the cooling unit 8. Therefore, in the first air passage F1, when the dehumidifier 100 is operated with the heater 6 turned off, it is possible to prevent the air heated by the heat of the heat radiating unit 9 from flowing to the cooling unit 8, so that the heat radiating unit 9 It is possible to prevent the temperature of the cooling unit 8 from rising due to the heat of the cooling unit 8. As a result, it is possible to suppress a decrease in the cooling efficiency of the cooling unit 8 due to the refrigeration cycle, so that it is possible to suppress a decrease in the dehumidifying capacity of the dehumidifier 100.

Further, in the first air passage F1, the cooling unit 8 and the moisture absorbing unit 7b are arranged in the order of the cooling unit 8 and the moisture absorbing unit 7b. In the first air passage F1, air flows in the order of the cooling unit 8 and the moisture absorbing unit 7b. The air flowing through the first air passage F1 is dehumidified by dew condensation of moisture in the air by the cooling unit 8. Further, the air flowing through the first air passage F1 is dehumidified by the moisture absorbing portion 7b. As a result, the amount of dehumidified air can be improved, so that the air can be effectively dried.

Further, the air that has passed through the moisture releasing portion 7a is supplied to the cooling portion 8 along the vertical direction. Therefore, the time required for the air to pass through the cooling unit 8 can be increased, so that the cooling unit 8 can effectively cool the air.

Further, the heater 6 is arranged at a place separated from the heat radiating unit 9 along the vertical direction. Therefore, the thickness of the dehumidifier 100 can be reduced as compared with the case where the heater 6 and the heat radiating portion 9 are arranged side by side in the front-rear direction.

The heater 6 does not have to be arranged above the heat radiating unit 9. That is, in the first air passage F1, the heater 6, the moisture releasing portion 7a, the cooling portion 8, the moisture absorbing portion 7b, and the heat radiating portion 9 are formed by the heater 6, the moisture releasing portion 7a, the cooling portion 8, and the moisture absorbing portion 7b. , And, as long as the heat radiating portions 9 are arranged in this order, the arrangement location of the heater 6 is not particularly limited. As a result, the degree of freedom in the installation location of the heater 6 can be improved.

The third embodiment is different from the second embodiment in that each of the third air passage F3 and the fourth air passage F4 can be opened and closed. Hereinafter, the differences from the second embodiment will be mainly described.

As shown in FIG. 7, the dehumidifier 100 further includes a damper 16.

The damper 16 opens and closes each of the third air passage F3 and the fourth air passage F4. The damper 16 includes a shielding portion 16a, a supporting portion 16b, and a first drive source (not shown). The damper 16 is an example of the opening / closing member of the present invention.

The shielding portion 16a is a substantially plate-shaped member. The support portion 16b rotatably supports the shielding portion 16a with respect to the casing 1. The support portion 16b includes, for example, a shaft member and a bracket. The shaft member is attached to the shielding portion 16a. The bracket is fixed to the casing 1 and rotatably supports the shaft member. The first drive source rotates the shielding portion 16a. The first drive source includes, for example, a motor. The first drive source is controlled by the control unit 14.

The posture of the damper 16 is changed by changing the rotation angle of the shielding portion 16a by the first drive source.

FIG. 7 shows the damper 16 of the first posture α1. As shown in FIG. 7, the damper 16 in the first posture α1 closes the third air passage F3 and the fourth air passage F4 by the shielding portion 16a. As a result, when the damper 16 is in the first posture α1, the first air passage F1 and the second air passage F2 are formed inside the casing 1.

FIG. 8 is a diagram showing a damper 16 in the second posture α2. As shown in FIG. 8, the damper 16 in the second posture α2 closes the fourth air passage F4 by the shielding portion 16a, but opens the third air passage F3. As a result, when the damper 16 is in the second posture α2, the first air passage F1, the second air passage F2, and the third air passage F3 are formed inside the casing 1.

FIG. 9 is a diagram showing a damper 16 in the third posture α3. As shown in FIG. 9, the damper 16 in the third posture α3 opens the third air passage F3 and the fourth air passage F4.

In a high temperature and high humidity environment such as summer, the air can be sufficiently dehumidified by the dehumidifier 100 even when the heater 6 is OFF. In this case, the damper 16 reduces the amount of air flowing through the first air passage F1 per unit time by opening each of the third air passage F3 and the fourth air passage F4. On the other hand, in a low temperature and low humidity environment such as winter, the dehumidifier 100 can effectively dehumidify the air by turning on the heater 6. In this case, the damper 16 closes each of the third air passage F3 and the fourth air passage F4 to increase the amount of air flowing through the first air passage F1 per unit time.

The second example of the process of adjusting the amount of air flowing through the first air passage F1 per unit time by the damper 16 will be described.

When it is desired to reduce the driving noise of the dehumidifier 100, the rotation speed of the fan included in the blower portion 11 is reduced.

The supply unit 17 is, for example, a metal rod-shaped member. The supply unit 17 is fixed to the heat dissipation unit 9 and projects to the periphery of the heater 6. In the fourth embodiment, the supply unit 17 projects onto the first air passage portion F11. Therefore, since the heat generated by the heat radiating unit 9 is supplied to the air flowing through the first air passage portion F11 through the supply unit 17, the air is generated not only by the heat of the heater 6 but also by the heat of the heat radiating unit 9. Can be heated. As a result, the air can be effectively heated.

The supply unit 17 may also be provided for each of the dehumidifier 100 of the second embodiment (see FIG. 6) and the dehumidifier 100 of the third embodiment (see FIGS. 7 and 10).

[Fifth Embodiment]
The heating unit 61, which is a modified example of the heater 6, will be described with reference to FIG. FIG. 13 is a diagram showing a heating unit 61. The heating unit 61 is two examples of the heating unit of the present invention.

As shown in FIG. 13, the fifth embodiment is different from the first embodiment in that the heating unit 61 is used instead of the heater 6. Hereinafter, the differences from the first embodiment will be mainly described.

The heating unit 61 supplies the heat generated in the refrigeration cycle to the air, for example, upstream of the moisture release unit 7a. In this case, the heating unit 61 is a portion of the tubular member through which the refrigerant is circulated in the refrigeration cycle, which is located between the compression unit 12 and the expansion unit, and the high-temperature refrigerant sent from the compression unit 12 is used. It flows. The heating unit 61 is arranged upstream of the moisture release unit 7a. Upstream of the moisture release section 7a, the air is heated by the heat of the refrigerant generated from the heating section 61. As a result, the air heated by the heating unit 61 is supplied to the moisture releasing unit 7a.

Note that, as the heating unit 61, a supply unit 17 as shown in FIGS. 11 and 12 may be used. In this case, the supply section 17 is arranged upstream of the moisture release section 7a, and the heat of the heat dissipation section 9 is supplied upstream of the moisture release section 7a via the supply section 17. As a result, the air heated by the heat of the heat radiating section 9 is supplied to the moisture releasing section 7a.

Further, also in the second to fourth embodiments, the heating unit 61 may be used instead of the heater 6.

As described above with reference to FIG. 13, by using the heating unit 61 instead of the heater 6, the electric power for operating the heater 6 becomes unnecessary, so that the running cost of the dehumidifier 100 can be reduced. Further, since the air is always heated by the heat generated in the refrigeration cycle or the heat generated in the heat radiating unit 9 and the heated air is supplied to the moisture releasing unit 7a, the efficiency is achieved by using the moisture releasing unit 7a. Can be dehumidified well.

[Sixth Embodiment]
The dehumidifier 100 according to the sixth embodiment of the present invention will be described with reference to FIG. FIG. 14 is a schematic view showing the inside of the dehumidifier 100 according to the sixth embodiment of the present invention.

As shown in FIG. 14, in the first air passage F1, the moisture releasing portion 7a, the cooling portion 8, the moisture absorbing portion 7b, and the heat radiating portion 9 are provided in the heat radiating portion 9, the moisture releasing portion 7a, and the cooling portion 8. The moisture absorbing portion 7b and the heat radiating portion 9 are arranged in this order. Therefore, the air supplied from the outside of the casing 1 to the first air passage F1 flows in the order of the heat radiating section 9, the moisture releasing section 7a, the cooling section 8, the moisture absorbing section 7b, and the heat radiating section 9, and then the casing 1. It is discharged to the outside. As a result, the air heated by the heat generated in the heat radiating unit 9 can be supplied to the moisture releasing unit 7a. That is, the heat radiating unit 9 can function as a substitute for the heater 6 of the first embodiment.

Further, by not using the heater 6, the running cost of the dehumidifier 100 can be reduced because the electric power for operating the heater 6 is not required. Further, since the air is always heated by the heat generated by the heat radiating section 9 and the heated air is supplied to the moisture releasing section 7a, the moisture releasing section 7a can be used for efficient dehumidification. Further, the air flowing through the heat radiating section 9 (air having substantially the same temperature as the outside air) upstream of the moisture releasing section 7a and the air flowing through the heat radiating section 9 downstream of the moisture absorbing section 7b (air cooled by the cooling section 8). As a result, the heat radiating unit 9 can be effectively cooled.

Further, also in the second to fourth embodiments, the heat radiating unit 9 may be used instead of the heater 6.

FIG. 17 is a schematic view of the dehumidifier 100 according to the seventh embodiment of the present invention as viewed from the rear.

The seventh embodiment is different from the first embodiment in that the flow direction of the air flowing through the moisture releasing portion 7a and the flowing direction of the air flowing through the moisture absorbing portion 7b are the same. Hereinafter, the differences from the first embodiment will be mainly described.

The location of various components of the dehumidifier 100 will be described.

As shown in FIGS. 15 to 17, a third suction port 3c is formed in the casing 1 in place of the first suction port 3a.

The third suction port 3c is formed on the rear surface of the casing 1. The third suction port 3c communicates the inside and the outside of the casing 1. The third suction port 3c is arranged on the rear surface of the casing 1 at the upper part and at the center of the left and right sides. A heater 6 is arranged in front of the third suction port 3c, and a moisture releasing portion 7a is arranged in front of the heater 6. The heater 6 faces the third suction port 3c. A cooling unit 8 is arranged below the heater 6. A moisture absorbing portion 7b is arranged in front of the cooling portion 8, and a heat radiating portion 9 is arranged in front of the moisture absorbing portion 7b.

An air passage FA is formed inside the casing 1. The air that has flowed into the inside of the casing 1 flows along the air passage FA.

Subsequently, the air passage FA will be described with reference to FIGS. 15 to 17.

As shown in FIGS. 15 to 17, the air passage FA includes a first air passage portion F11A, a pair of second air passage portions F12A, a pair of third air passage portions F13A, and a pair of fourth air passage portions. Includes F14A and a pair of fifth air passage portions F15A.

The first air passage portion F11A communicates with the third suction port 3c and extends forward from the third suction port 3c. The first air passage portion F11A passes through the heater 6 and the moisture releasing portion 7a.

A pair of second air passage portions F12A are connected to the front end portion F1A of the first air passage portion F11A. The pair of second air passage portions F12A extend in opposite directions (left-right direction) so as to branch off from the front end portion F1A of the first air passage portion F11A.

The pair of second air passage portions F12A correspond to the pair of third air passage portions F13A, the pair of fourth air passage portions F14A, and the pair of fifth air passage portions F15A, respectively, and the corresponding second air passage portions. F12A to the fifth air passage portion F15A are connected in order. That is, two sets of air passages composed of the second air passage portion F12A to the fifth air passage portion F15A are formed inside the casing 1.

The third air passage portion F13A extends backward from the tip portion F2A of the second air passage portion F12A. The fourth air passage portion F14A extends downward from the rear end portion F3A of the third air passage portion F13A. The fourth air passage portion F14A is formed in the cooling portion 8. The fifth air passage portion F15A extends forward from the lower end portion F4A of the fourth air passage portion F14A. The fifth air passage portion F15A passes through the moisture absorbing portion 7b and the heat radiating portion 9. The fifth air passage portion F15A leads to the blower portion 11.

Explain multiple walls.

The plurality of wall portions partition the inside of the casing 1 so that the air passage FA is formed inside the casing 1. The plurality of wall portions includes a pair of facing wall portions 15α.

The pair of facing wall portions 15α are arranged so as to be spaced apart from each other in the left-right direction. A first air passage portion F11A is formed inside the pair of facing wall portions 15α. A heater 6 and a moisture releasing portion 7a are arranged inside the pair of facing wall portions 15α. Third air passage portions F13A are formed on the left and right outer sides of the pair of facing wall portions 15α, respectively.

The facing wall portion 15α is located between the first air passage portion F11A and the third air passage portion F13A. The facing wall portion 15α includes a shielding portion (guard portion) 15β. The shielding portion 15β is a portion of the facing wall portion 15α facing the moisture releasing portion 7a. The shielding portion 15β is located between the moisture releasing portion 7a and the third air passage portion F13A. The shielding portion 15β is formed so as to bulge outward to the left and right along the shape of the moisture releasing portion 7a, thereby restricting the moisture releasing portion 7a from protruding into the third air passage portion F13A.

The plurality of wall portions include the third wall portion 15c to the fourth wall portion 15d. The third wall portion 15c is located in front of the facing wall portion 15α. The fourth wall portion 15d is located below the first air passage portion F11A to the third air passage portion F13A. A pair of holes S1 are formed in the fourth wall portion 15d. The hole S1 is located above the cooling unit 8 and faces the cooling unit 8.

The plurality of wall portions further include the sixth wall portion 15f to the eighth wall portion 15h. The sixth wall portion 15f is located between the cooling portion 8 and the dehumidifying rotor 7. The seventh wall portion 15g is located behind the third air passage portion F13A and faces the third air passage portion F13A. The eighth wall portion 15h is located behind the fourth air passage portion F14A. The eighth wall portion 15h is located behind the cooling portion 8 and faces the cooling portion 8.

The air flow inside the casing 1 will be described.

When the blower portion 11 operates, the air outside the casing 1 flows into the inside of the casing 1 through the third suction port 3c. The air that has flowed into the casing 1 flows into the first air passage portion F11A, flows forward, and passes through the heater 6 and the moisture releasing portion 7a. Then, the air flows in the order of the second air passage portion F12A and the third air passage portion F13A. The air flowing through the third air passage portion F13A is guided by the seventh wall portion 15g and flows into the fourth air passage portion F14. After passing through the hole S1, the air flowing into the fourth air passage portion F14 flows downward while being guided by the sixth wall portion 15f and the eighth wall portion 15h. Then, when the air moves below the lower end fa of the sixth wall portion 15f, it flows into the fifth air passage portion F15A. The air that has flowed into the fifth air passage portion F15A passes through the moisture absorbing portion 7b and the heat radiating portion 9 while flowing in the forward direction. The air that has passed through the heat radiating unit 9 is discharged to the outside of the casing 1 through the air outlet 2.

As described above with reference to FIGS. 15 to 17, in the air passage FA, the flow direction of the air flowing through the moisture releasing portion 7a and the flow direction of the air flowing through the moisture absorbing portion 7b are the same (forward direction). (See FIG. 15). As a result, the wind from the moisture releasing portion 7a to the cooling portion 8 is compared with the case where the flow direction of the air flowing through the moisture releasing portion 7a and the flowing direction of the air flowing through the moisture absorbing portion 7b are opposite (see FIG. 2). The distance of the road can be increased. According to this, it is possible to extend the time for the air discharged from the dehumidifying unit 7a to be cooled by the temperature difference from the outside air of the dehumidifier 100 until it is supplied to the cooling unit 8. As a result, the air can be supplied to the cooling unit 8 in a state of being cooled to some extent, so that the cooling unit 8 can further cool the air and effectively perform the dehumidifying treatment.

Further, as shown in FIGS. 15 and 16, the heater 6 faces the third suction port 3c. As a result, the heater 6 can be installed in a place that is easily visible from the outside of the casing 1. As a result, the user can easily confirm the state of adhesion of dust or the like to the heater 6, so that the maintainability of the dehumidifier 100 can be improved.

Further, as shown in FIG. 16, the shielding portion 15β of the facing wall portion 15α is located between the moisture releasing portion 7a and the third air passage portion F13A. As a result, the air flowing through the third air passage portion F13A is blocked by the shielding portion 15β from flowing into the moisture releasing portion 7a. According to this, when the air having become high humidity by flowing through the moisture-releasing portion 7a on the first air passage portion F11A flows into the moisture-releasing portion 7a again when flowing through the third air passage portion F13A, it is released. It is possible to regulate dehumidification by the zeolite 71 located in the wet portion 7a. As a result, the high-humidity air generated in the moisture-releasing portion 7a on the first air passage portion F11A is cooled through the second air passage portion F12A to the fourth air passage portion F14A while maintaining the high humidity state. Since it can be supplied to 8, the cooling unit 8 can effectively dehumidify.

The facing wall portion 15α is an example of the wall portion of the present invention. The shielding portion 15β is an example of the shielding portion of the present invention. The third air passage portion F13A is an example of the air passage portion of the present invention.

In the seventh embodiment, one eighth wall portion 15h is provided. However, the present invention is not limited to this. A pair of eighth wall portions 15h may be provided at intervals on the left and right. In this case, a pair of eighth wall portions 15h are provided at locations facing each other with the pair of fourth air passage portions F14.

Next, a modified example of the dehumidifier 100 (see FIGS. 15 to 17) according to the seventh embodiment of the present invention will be described with reference to FIG. FIG. 18 is a schematic view of a modified example of the dehumidifier 100 according to the seventh embodiment of the present invention as viewed from the rear.

As shown in FIG. 18, in the modified example of the dehumidifier 100, the vertical dimension of the eighth wall portion 15h can be changed.

An example of the structure of the eighth wall portion 15h will be described.

The eighth wall portion 15h is divided into an upper portion h1 and a lower portion h2. The upper portion h1 faces the upper portion of the cooling unit 8. The upper portion h1 is integrally formed with another wall portion. The lower portion h2 is slidably attached to the upper portion h1 in the vertical direction. By sliding the lower portion h2 in the vertical direction with respect to the upper portion h1, the vertical dimension of the eighth wall portion 15h is changed. As the amount of downward sliding of the lower portion h2 with respect to the upper portion h1 increases, the vertical dimension of the eighth wall portion 15h becomes larger. The larger the vertical dimension of the eighth wall portion 15h, the wider the region of the cooling portion 8 facing the eighth wall portion 15h.

The wider the region facing the eighth wall portion 15h, the larger the amount of air supplied to the cooling portion 8 through the first air passage portion F11A to the fourth air passage portion F14A shown in FIG. The amount of air supplied through the heater 6 and the zeolite 71) increases, and the amount of air supplied through the second air passage F2 and the third air passage F3 shown in FIG. 6 (the amount of air supplied through the heater 6 and the zeolite 71) increases. The amount of air supplied without going through) is reduced.

When the temperature of the outside air becomes low, the amount of saturated water vapor in the air decreases. In this case, in order to improve the dehumidifying efficiency of the dehumidifier 100, it is preferable to lengthen the vertical dimension of the eighth wall portion 15h to increase the amount of air passing through the heater 6 and the zeolite 71. In this case, the dehumidifier 100 mainly functions as a zeolite-type dehumidifier.

On the other hand, when the temperature of the outside air rises, the amount of saturated water vapor in the air increases. In this case, in order to improve the dehumidifying efficiency of the dehumidifier 100, it is preferable to shorten the vertical dimension of the eighth wall portion 15h to reduce the amount of air passing through the heater 6 and the zeolite 71. In this case, the dehumidifier 100 mainly functions as a compressor type dehumidifier.

The vertical dimension of the eighth wall portion 15h may be changed by the operator or may be changed by the control unit 14 (see FIG. 15).

The apparatus configuration when the control unit 14 changes the vertical dimension of the eighth wall portion 15h will be described. In this case, the dehumidifier 100 includes, for example, a temperature sensor and an actuator. The temperature sensor is installed inside the casing 1 (for example, the third suction port 3c). The actuator includes, for example, a motor and moves the lower portion h2 of the eighth wall portion 15h up and down. When the detection temperature of the temperature sensor becomes less than a predetermined value, the control unit 14 controls the actuator so that the lower portion h2 is located at the first predetermined position. On the other hand, when the detection temperature of the temperature sensor becomes equal to or higher than a predetermined value, the control unit 14 controls the actuator so that the lower portion h2 is located at the second predetermined position higher than the first predetermined position. As a result, the vertical dimension of the eighth wall portion 15h can be adjusted according to the air temperature, so that the dehumidifying efficiency of the dehumidifier 100 can be effectively improved.

The vertical dimension of the eighth wall portion 15h may be set according to the shipping location of the dehumidifier 100. For example, the higher the average temperature at the shipping location of the dehumidifier 100, the smaller the vertical dimension of the eighth wall portion 15h is set.

As described above, the dimensions of the 8th wall portion 15h can be changed. As a result, even if the type of the heater 6 (heating function) and / or the type of the moisture releasing portion 7a (humidifying function) is changed in design, the type of the heater 6 and / or the type of the moisture releasing portion 7a is changed. Since the vertical dimension of the eighth wall portion 15h can be adjusted accordingly, the degree of freedom in designing the dehumidifier 100 can be improved.

The embodiments of the present invention have been described above with reference to the drawings (FIGS. 1 to 18). However, the present invention is not limited to the above-described embodiment, and can be implemented in various embodiments without departing from the gist thereof. In addition, various inventions can be formed by appropriately combining the plurality of components disclosed in the above embodiments. For example, some components may be removed from all the components shown in the embodiments. The drawings are schematically shown mainly for each component for easy understanding, and the number of each component shown may differ from the actual one due to the convenience of drawing. Further, each component shown in the above embodiment is an example, and is not particularly limited, and various modifications can be made without substantially deviating from the effect of the present invention.

The present invention can be used in the field of dehumidifiers.
