Description

  The present invention relates to a dehumidifier having a mechanism for circulating a refrigerant.

  During rainy seasons, the indoor air contains a large amount of moisture, increasing discomfort and creating an environment suitable for the propagation of germs and fungi. Moisture in the air moisturizes clothes, futons, tatami mats, and carpets, and causes them to generate mold. In particular, in a sealed indoor space such as a condominium, ventilation capacity is low, and generation of mold due to moisture is a problem. Dehumidifiers play an active role in removing such moisture.

A conventional general dehumidifier removes moisture in the air by a refrigeration cycle as disclosed in Patent Document 1. That is, the refrigerant compressed by the compressor is circulated in the path of the condenser (condenser) → dryer → capillary tube → evaporator (evaporator) → compressor to cool the evaporator, and the condensing unit adjacent to it While the condenser is heated, the moisture in the air is attached to the evaporator as the evaporation section, and the dried air is blown out from the top or front of the dehumidifier to dehumidify the room. FIG. 10 shows this type of dehumidifier, and an up-life wrap 9 and a down-life wrap 10 that can change the angle are provided at the air outlet 3 provided at the upper part of the main body 1, and the blowing angle of the dry air Can be adjusted. In such a dehumidifier that can adjust the blowing angle, it can be used for so-called floor surface drying for drying tatami mats and carpets, in this case, the angle of the down life wrap 10 provided at the outlet 3 is directed to the floor surface, Floor surface drying is performed by blowing dry air F toward the floor surface. On the other hand, the uplife wrap 9 is used when the laundry is dried in the room, and can be used as a clothes dryer by adjusting the angle of the uplife wrap 9 so that dry air directly hits the laundry.

  However, the conventional dehumidifier has a problem that it cannot be re-operated immediately after the operation is stopped. In a dehumidifier having a refrigeration cycle, as described above, the refrigerant is compressed into a high pressure by the compressor, and when it passes through the capillary tube, it expands to a low pressure. A pressure difference occurs. When the re-operation is started with the pressure difference remaining, the internal pressure of the condenser is high, so that the compressor cannot be started and is locked, and problems such as operation of the compressor protection device occur. Therefore, when the dehumidifier is stopped and restarted, measures are taken to reduce the internal pressure of the condenser, for example, by installing a control (compressor OFF time) that does not start the compressor for a minimum of 3 minutes. However, during the compressor OFF time, even if the dehumidifier was operated, the compressor was still stopped and could not be restarted immediately.

  Further, after the operation of the dehumidifier is stopped, moisture has adhered to the evaporator, so that mold and bacteria contained in the air may be propagated in the evaporator. If mold and bacteria propagate in the dehumidifier, there is a risk that mold spores and bacteria may be released from the dehumidifier into the room when the dehumidifier is operated.

  As shown in FIG. 10, the general dehumidifier outlet 3 is located at the upper front of the main body 1, and even if the blowout angle is adjusted by the down life wrap 10, the floor immediately below the outlet 3. As a result, the dry air F could not be blown on the surface, resulting in blind spots. In addition, the dry air F blown from the dehumidifier is higher in temperature than room temperature and low in humidity, so its specific gravity is lighter than the outside air (room damp air) and blown toward the floor. However, the floor surface close to the main body 1 can be dried in a short time, but the drying of the floor surface several meters away from the main body 1 does not reach much, so it takes time to dry. Needed.

  Therefore, in view of the above problems, the first object of the present invention is to provide a dehumidifier that reduces the load on the compressor and enables reliable start even when re-operation is started immediately after operation stop. And

  It is a second object of the present invention to provide a dehumidifier that suppresses the growth of mold and bacteria in the dehumidifier.

  Furthermore, it is a third object to provide a dehumidifier that exhibits high drying performance on the floor surface.

  In the dehumidifier according to the first aspect of the present invention, even when the high-pressure refrigerant is filled inside the condensing unit constituting the cooling path when the dehumidifying operation is restarted, the condensing unit and the evaporating unit are formed by the heating path. However, since the high-pressure refrigerant instantaneously escapes to the evaporation section by communicating without going through the other constituent means, the pressure difference in the cooling path is quickly reduced, and the load on the compression section is reduced for a short time. Can be greatly reduced. Originally, during the dehumidifying operation, the refrigerant is circulated through the cooling path, but the dehumidifier is stopped only by switching the path through which the refrigerant circulates from the cooling path to the heating path for a predetermined time at the start of the dehumidifying operation. You can resume operation soon. Further, since existing constituent means can be used, there is no need to add parts.

  In the dehumidifier according to claim 2 of the present invention, the switching means switches the gas blowing path from the blowing section to the flow path, so that the gas blown by the blowing means blows out from the blowing section to the outside. Instead, it is returned to the internal mechanism and distributed inside. At this time, by applying the gas to the mechanism and drying, the moisture attached to the mechanism is removed, so that it is possible to prevent the breeding even if mold or germs adhere.

  In the dehumidifier according to the third aspect of the present invention, by providing the gas blowing part at the lower part, the gas can be distributed to the floor surface in the vicinity of the main body, so there is no blind spot with respect to the floor surface, and the floor surface drying performance is improved. improves. Since the suppression means allows the gas to flow along the floor surface without rising, it can be effectively dried even on the floor surface away from the main body, and the drying speed can be increased. Further, since the restraining means is provided in the main body so as to be storable, it does not get in the way when not in use and does not take up a storage space.

  Since the present invention is as described above, the following effects can be obtained.

  According to the first aspect of the present invention, it is possible to reduce the load at the time of starting the compression section, enable a reliable start, and restart the operation immediately after the operation of the dehumidifier is stopped.

  According to claim 2 of the present invention, it is possible to keep molds and germs from growing inside the dehumidifier and keep them clean.

  According to claim 3 of the present invention, as the drying speed can be increased, the operation time can be shortened, resulting in energy saving.

  Hereinafter, preferred embodiments of a dehumidifier according to the present invention will be described with reference to the accompanying drawings. Note that, in each of these embodiments, the same portions as those in the conventional example are denoted by the same reference numerals, and the description of the common parts will be omitted as much as possible.

  Hereinafter, a first embodiment of a dehumidifier according to the present invention will be described with reference to the accompanying drawings. The basic configuration of the dehumidifier in the present embodiment is substantially the same as the dehumidifier shown in the conventional example except for the control means 36 described later. In FIG. 1 to FIG. 3 showing the appearance of the dehumidifier, 1 is a main body of a vertically long box-shaped dehumidifier, and a suction port 2 for taking in air is provided on the side of the main body 1 and on the upper rear side. An air outlet 3 is provided in front of the upper portion of the main body 1 as an air outlet for sending dry air that is a gas. A water storage tank 5 made of transparent resin is detachably provided in the opening 4 formed on one side of the main body 1. A display / operation panel 6 includes a plurality of LEDs and various switches, for example. A rotatable handle 7 is provided at the top of the main body 1 so as to surround the display / operation panel 6 in a U-shape.

  The blowout port 3 is provided with an uplife wrap 9 and a downlife wrap 10 that are opened when dry air is delivered.

  The display / operation panel 6 includes a dehumidifying button 12, an operation switching button 13, and a turn-off timer button 14 that constitute an operation means 40 described later. Corresponding to these buttons, a full water lamp 20 that is turned on when the water storage tank 5 is full is provided as a display means 39 together with a humidity lamp 16, an operation switching lamp 17, and a turn-off timer lamp 18.

  FIG. 4 schematically shows the configuration of the refrigeration cycle mechanism 21 provided inside the main body 1. In the figure, a refrigeration cycle mechanism 21 includes a compressor 22 as a compression unit that circulates (circulates) a refrigerant, a condenser 23 as a condensation unit that releases heat in the refrigerant, a dryer 24, and a capillary tube as an expansion unit. 25 and an evaporator 26 as an evaporator corresponding to a heat exchanger that condenses moisture in the air are sequentially connected, and in parallel with a path from the evaporator 26 to the compressor 22, as a refrigeration cycle switching unit 2 way valve 27 is provided. Reference numeral 28 denotes a temperature sensor as a frost detection means provided in the evaporator 26. When the temperature sensor 28 detects frost formation on the evaporator 26, the two-way valve 27 is opened. When the two-way valve 27 is closed, a cooling circulation path 29 is formed as a cooling path through which the refrigerant circulates in the path of the compressor 22 → the condenser 23 → the dryer 24 → the capillary tube 25 → the evaporator 26 → the compressor 22. The When the two-way valve 27 is opened, a heating circulation path 30 is formed as a heating path from the compressor 22 → the two-way valve 27 → the evaporator 26 → the compressor 22. In addition, the refrigeration cycle mechanism 21 is provided with a blower 31 as a blowing means for sending air from the outside to the evaporator 26.

  FIG. 5 is a block diagram showing the configuration of the controller 35 incorporated in the main body 1 and its periphery. In the figure, a controller 35 includes a microcomputer (hereinafter referred to as a microcomputer) 38 having a control means 36 and a blower rotational speed adjusting means 37, and a display means 39 for displaying an operation state provided in the display / operation panel 6 described above. And operation means 40 including various buttons. The control unit 36 includes temperature information from the temperature sensor 28 and the room temperature sensor 42 for detecting the temperature of the evaporator 26, an operation signal from the operation unit 40, and a load current detection unit 43 for detecting a load current flowing through the compressor 22. The rotation speed of the blower 31 and the display of the display means 39 are controlled based on the detection information from the sensor, the time information of the built-in timer (not shown), and the humidity information from the humidity sensor 44 that detects the ambient humidity. It has a function to do. The blower rotation speed adjusting means 37 adjusts the rotation speed of the blower 31 to, for example, either a strong air amount or a weak air amount based on a control signal from the control means 36.

  Next, the operation of the above configuration will be described. When the operation means 40 is operated to instruct the start of the dehumidifying operation, the control means 36 outputs a signal for driving the compressor 22 and sends a signal for driving the blower 31 at a predetermined rotational speed to the blower rotational speed adjusting means 37. Output. As a result, the compressor 22 and the blower 31 are driven to start the dehumidifying operation of either the strong air amount or the weak air amount.

  During this dehumidifying operation, since the two-way valve 27 is closed by a control signal from the control means 36, the refrigerant compressed by the compressor 22 circulates through the cooling circuit 29 without passing through the two-way valve 27. That is, the refrigerant enters the condenser 23 from the compressor 22, releases heat in the refrigerant, and then enters the capillary tube 25 from the dryer 24 and is expanded. Thereafter, the refrigerant evaporates in the evaporator 26, and heat is taken from the heat exchange fins 52 of the evaporator 26, the temperature of the evaporator 26 is lowered, and the flow returns to the compressor 22 again. At that time, the indoor air sucked into the main body 1 by the blower 31 is touched to the evaporator 26 to be cooled and dehumidified, and the cooled air is heated by the condenser 23 to be dried as dry air from the outlet 3 of the main body 1 to the outside. Discharged.

  On the other hand, when the room temperature is low and frost adheres to the evaporator 26, the temperature detected by the evaporator 26 by the temperature sensor 28 decreases. The control means 36 detects the frost formation of the evaporator 26 when the detected temperature from the temperature sensor 28 is a predetermined temperature, for example, 0 ° C. or less, for a certain period of time or longer. The control of the refrigeration cycle mechanism 21 is switched. Specifically, the two-way valve 27 is opened by the control means 36, and the refrigerant from the compressor 22 is sent directly to the evaporator 26 via the two-way valve 27 without passing through the condenser 23. As a result, the evaporator 26 releases the heat of the refrigerant to increase the temperature, and melts frost adhering to the evaporator 26. The refrigerant that has passed through the evaporator 26 returns to the compressor 22 again, and continues the defrosting operation until the temperature detected by the temperature sensor 28 rises.

  Further, during the dehumidifying operation, the control means 36 monitors the load state of the compressor 22 based on the detection information from the load current detection means 43. When the load of the compressor 22 is less than the set value, the operation of a weak air volume is performed to reduce the rotation speed of the blower 31. On the other hand, if the load on the compressor 22 is greater than or equal to the set value, the control unit 36 determines the current operating state of the blower 31 and if it is a strong air volume, it remains as it is; Therefore, the operation is automatically switched to the operation of the high air flow rate that increases the rotation speed of the blower 31.

  Thereafter, when an operation for stopping the dehumidifying operation is performed by the operation means 40, the control means 36 stops the driving of the compressor 22 and the blower 31.

  Here, if the re-operation is started immediately after the dehumidification operation is stopped, the compressor 22 starts operation with the refrigerant flow during the dehumidification operation, but the load on the compressor 22 is increased because the internal pressure of the condenser 23 is increased. Is big. The pressure (refrigerant) inside the condenser 23 passes through the capillary tube 25 to the evaporator 26. However, since the passage amount per unit time of the capillary tube 25 is small, the internal pressure of the condenser 23 and the internal pressure of the evaporator 26 are substantially the same. , Takes a few minutes. Therefore, in this embodiment, by opening the two-way valve 27 during re-operation, the refrigerant circulation path is switched, the difference between the condenser 23 internal pressure and the evaporator 26 internal pressure is reduced, and the load on the compressor 22 is reduced. Yes. That is, when the dehumidifying operation is re-operated by the operating means 40, the control means 36 opens the two-way valve 27 for a certain period of time to form the heating circulation path 30, whereby the high pressure in the condenser 23 is The refrigeration cycle mechanism 21 is switched and controlled so that the refrigerant is allowed to escape to the evaporator 26. Then, the refrigerant circulation path starts from the cooling circulation path 29 that circulates through the capillary tube 25 with a small passage amount per unit time, and passes through the two-way valve 27 that has a larger passage amount per unit time than the capillary tube 25. Therefore, the pressure inside the condenser 23 can be instantaneously released to the evaporator 26 through the two-way valve 27 and the heating circuit 30.

  Next, the control means 36 closes the two-way valve 27 after a predetermined time has elapsed, thereby switching from the heating circulation path 30 to the cooling circulation path 29, outputting a signal for driving the compressor 22, and a predetermined rotation speed. By outputting a signal for driving the blower 31 to the blower rotation speed adjusting means 37, the operation of the compressor 22 and the dehumidifying operation are resumed. In the heating circuit 30, the internal pressure of the condenser 23 and the internal pressure of the evaporator 26 are instantaneously substantially the same, so the predetermined time for forming the heating circuit 30 may be only a few seconds, and it can be restarted in a short time after the dehumidification operation is stopped. Operation can be started. Note that a means for detecting the internal pressure of the capacitor 23 may be provided, and the two-way valve 27 may be controlled to be switched according to the detection result, and the sequence circuit is configured by a relay or the like without using the control means 36. Then, the two-way valve 27 may be switched and controlled.

As described above, in this embodiment, the cooling circuit 29 is provided with the compressor 22 that compresses the refrigerant, the condenser 23 that circulates the refrigerant during the dehumidifying operation, and the evaporator 26 that functions as the condensing unit. A refrigeration cycle that is a refrigeration mechanism including a heating circuit 30 that circulates the refrigerant during the defrosting operation, and a two-way valve 27 that is a refrigeration cycle switching unit that switches the cooling circuit 29 and the heating circuit 30 In the dehumidifier that includes the mechanism 21 and performs dehumidification by controlling the refrigeration cycle mechanism 21 by the control means 36, the control means 36 uses the two-way valve 27 to start the cooling only for a predetermined time when starting the dehumidification operation. Switch from the circuit 29 for heating to the circuit 30 for heating,
The capacitor 23 and the evaporator 26 are directly communicated with each other.

  In this way, when restarting from the dehumidifying operation stop, even if the high-pressure refrigerant is filled inside the condenser 23 constituting the cooling circuit 29, the condenser 23 and the evaporator 26 are connected by the heating circuit 30. Since the high-pressure refrigerant is instantaneously removed to the evaporator 26 by direct communication without passing through the other constituent means, the pressure difference in the cooling circuit 29 is quickly reduced, and the load applied to the compressor 22 is shortened. It can be greatly reduced in time. Originally, during the dehumidifying operation, the refrigerant is circulated in the cooling circulation path 29, but the refrigerant circulation path is switched from the cooling circulation path 29 to the heating circulation path 30 only for a predetermined time before the compressor 22 is operated. The operation can be resumed immediately after the dehumidifier is stopped. Further, since existing constituent means can be used, there is no need to add parts.

  Hereinafter, a second embodiment of the dehumidifier according to the present invention will be described with reference to the accompanying drawings. FIG. 6 is a cross-sectional view of the main part of the dehumidifier in the present embodiment. Similar to the first embodiment, the main body 1 of the dehumidifier, the suction port 2 for taking in air, and the blower for sending dry air. The main body 1 has a refrigeration cycle mechanism 21 including a compressor 22, a condenser 23, a dryer 24 (not shown), a capillary tube 25, an evaporator 26, and a two-way valve 27, and a blower 31. A detachable water storage tank 5 is provided.

  The blower outlet 3 is provided with an upgraded life wrap 9 that opens (opens) the blower outlet 3 when dry air is delivered, and a drive such as a motor (not shown), for example, according to a command signal from the control means 36 is provided. The opening and closing is controlled by the means.

  The upper part of the refrigeration cycle mechanism 21 in the main body 1 is provided with a dry air circulation path 50 as a flow path for sending the dry air blown from the blower 31 to the refrigeration cycle mechanism 21, and opens and closes the dry air circulation path 50. A damper 51 is provided to be rotatable. The damper 51 is interlocked with the uplife wrap 9, and is configured such that when the uplife wrap 9 is closed, the damper 51 is opened, and when the uplife wrap 9 is opened, the damper 51 is closed. The damper 51 may be opened by the wind pressure of dry air when the upgraded life wrap 9 is closed without being linked to the upgraded life wrap 9. FIG. 6 shows a state in which the uplife wrap 9 is opened and the damper 51 is closed. In this case, the dry air blown from the blower 31 blows out from the blowout port 3 as indicated by an arrow F1. Will be.

  Next, the operation of the above configuration will be described. When the operation means 40 is operated to instruct the start of the dehumidifying operation, the control means 36 outputs a signal for driving the compressor 22 and sends a signal for driving the blower 31 at a predetermined rotational speed to the blower rotational speed adjusting means 37. Output. As a result, the compressor 22 and the blower 31 are driven to start the dehumidifying operation of either the strong air amount or the weak air amount.

  During this dehumidifying operation, since the two-way valve 27 is closed by a control signal from the control means 36, the refrigerant compressed by the compressor 22 circulates through the cooling circuit 29 without passing through the two-way valve 27. At that time, the indoor air sucked into the main body 1 by the blower 31 is touched to the evaporator 26 to be cooled and dehumidified, and the cooled air is heated by the condenser 23 to be dried as dry air from the outlet 3 of the main body 1 to the outside. Discharged. When the dehumidifying operation is performed, moisture in the condensed air adheres to the evaporator 26 as water droplets, so that the water droplets eventually drop from the evaporator 26 and are stored in the water storage tank 5.

  Thereafter, when the operation unit 40 is operated to stop the dehumidifying operation, the control unit 36 normally stops the driving of the compressor 22 and the blower 31 immediately, but in this embodiment, the water adhering to the evaporator 26 is removed. Therefore, a drying operation is performed. In the drying operation, first, the control means 36 closes the uplife wrap 9 on the outlet 3 while continuing to drive the compressor 22 and the blower 31. FIG. 7 shows a state during the drying operation. As shown in FIG. 7, the damper 51 is opened in conjunction with the closing operation of the uplife wrap 9, so that the dry air is dried from the blower 31. It is sent to the refrigeration cycle mechanism 21 through the air circulation path 50. Therefore, the dry air circulates in the main body 1 in the order of the blower 31 → the dry air circulation path 50 → the refrigeration cycle mechanism 21 → the blower 31 as indicated by an arrow F2. At this time, the uplife wrap 9 and the damper 51 act as path switching means for switching the air blowing path of the dry air from the outlet 3 (arrow F1 in FIG. 6) to the dry air circulation path 50 (arrow F2 in FIG. 7). Therefore, the path switching means is not limited to the uplife wrap 9 and the damper 51, and may be configured in any way as long as the flow of the dry air can be switched from the blowout port 3 to the dry air circulation path 50. At the same time, the control means 36 opens the two-way valve 27 constituting the refrigeration cycle mechanism 21 to warm the evaporator 26. In this way, the evaporator 26 constituting the refrigeration cycle mechanism 21 is heated by the heat of the catalyst and is also exposed to dry air. In this state, for example, the drying operation is performed for a predetermined time of about 1 minute to 10 minutes. As a result, the water adhering to the evaporator 26 is evaporated and removed. By performing the drying operation before the dehumidifying operation is stopped, the moisture adhering to the evaporator 26 can be removed, so that the growth of mold and bacteria can be prevented, and the inside of the main body 1 can be kept clean. Therefore, the next time the dehumidifier is operated, mold spores and germs are not released from the dehumidifier into the room, which is hygienic.

  Then, the control means 36 stops the driving of the compressor 22 and the blower 31 and the drying operation after a predetermined time has elapsed. Similarly to the dehumidifying operation, the drying operation may be started by pushing an arbitrary drying button.

  As described above, the present embodiment includes the refrigeration cycle mechanism 21 that is a refrigeration mechanism for circulating the refrigerant, the blower 31 as a blower that blows dry air, and the air outlet 3 that blows the dry air out of the main body 1. In the dehumidifier, the dry air circulation path 50 for sending the dry air to the refrigeration cycle mechanism 21 and the up-drying unit corresponding to the path switching means for switching the air blowing path of the dry air from the blowout port 3 to the dry air circulation path 50. A flap 9 and a damper 51 are provided.

  If it does in this way, since it is comprised so that the blowing path of dry air may be switched from the blower outlet 3 to the dry air circulation path 50 by the uplife wrap 9 and the damper 51 which act as a path switching means, it blows with the air blower 31. The dry air is returned to the refrigeration cycle mechanism 21 inside the main body 1 without being blown out of the main body 1 from the air outlet 3 and circulates inside the main body 1. At this time, by applying dry air to the refrigeration cycle mechanism 21 for drying, moisture adhering to the refrigeration cycle mechanism 21 is removed, so that it is possible to prevent propagation even if mold or germs adhere. Therefore, the inside of the dehumidifier can be kept clean.

  In this embodiment, the control means 36 is configured to open the two-way valve 27 constituting the refrigeration cycle mechanism 21 and warm the evaporator 26 during the drying operation.

  In this way, the evaporator 26 constituting the refrigeration cycle mechanism 21 is warmed by the heat of the catalyst, so that evaporation and removal of water adhering to the evaporator 26 is promoted.

  Hereinafter, a third embodiment of the dehumidifier according to the present invention will be described with reference to the accompanying drawings. In the dehumidifier of the present embodiment, the configuration other than the blower outlet 3 and the wind direction plate 61 of the dehumidifier is substantially the same as that shown in the conventional example. FIG. 8 shows the appearance of the dehumidifier in the present embodiment. In FIG. 8, the air outlet 3 is provided in front of the lower portion of the main body 1. On the upper part of the blower outlet 3, a wind direction plate 61 as a rise restraining means for restraining (preventing) the rise of dry air blown out from the blower outlet 3 is pivotally supported by the main body 1 with the lower end as a rotation shaft. The front panel 60 of the main body 1 is formed with a concave portion 62 having a projection shape of the wind direction plate 61, and the wind direction plate 61 is accommodated in the concave portion 62 so as to be integrated with the main body 1. On the other hand, the wind direction plate 61 is configured to be locked at a position substantially horizontal to the floor surface so as to cover the upper portion of the air outlet 3. When the floor surface is dried, the wind direction plate 61 is used by being pulled down from the main body 1 so as to be rotated with the lower end as a rotation axis. Since the wind direction plate 61 is provided so as to be integrated with the main body 1 so as to be integrated, it does not get in the way when not in use, and does not take up storage space, so that the storage property during storage is high. Note that the wind direction plate 61 may be mechanically extendable and contractible, and the shape is not particularly limited as long as the increase in dry air can be suppressed.

  FIG. 9 shows the appearance of the dehumidifier when the floor surface is dried. Since the wind direction plate 61 is locked at a position where it covers the upper part of the air outlet 3, it blows out from the air outlet 3. The dry air F is suppressed from rising by the wind direction plate 61 and blown out from one end of the wind direction plate 61 into the room while strengthening the directionality in the horizontal direction. When the dry air F is blown out from the air outlet 3, the dry air F flows in the horizontal direction with respect to the floor surface, and dries moisture over the entire floor surface facing the wind direction plate 61, thereby drying the floor surface. At this time, the dry air F is cooled by the temperature of the room before reaching the end of the wind direction plate 61 and gradually loses its rising property as it includes moisture on the floor surface, so the directionality in the horizontal direction is increased. Further, it can be easily reached even in a place farther than the longitudinal direction of the wind direction plate 61. In addition, the reach distance of dry air can be extended by lengthening the longitudinal direction of the wind direction board 61. FIG. In this case, it is more effective to lengthen the longitudinal direction of the wind direction plate 61 and increase the blowing capacity.

  As described above, in this embodiment, in the dehumidifier having the refrigeration cycle mechanism 21 that is a refrigeration mechanism for circulating the refrigerant and the outlet 3 that blows dry air out of the main body 1, the outlet 3 is provided at the lower part of the main body 1. At the same time, a wind direction plate 61 serving as a rise restraining means for preventing the dry air from rising is located at the upper part of the air outlet 3 and is provided so as to be housed in the main body 1.

  If it does in this way, since the dry air can be spread over the floor surface near the main body 1 by providing the air outlet 3 for the dry air at the lower portion, there is no blind spot with respect to the floor surface, and the floor surface drying performance is improved. . The airflow direction plate 61 allows the dry air to flow along the floor surface without rising, so that it can be effectively dried even on the floor surface away from the main body 1 and the drying speed can be increased. Further, since the wind direction plate 61 is provided so as to be storable in the main body 1, it does not get in the way when not in use, and does not take up storage space, so that the storage property during storage is high. As described above, as the drying speed can be increased, the operation time can be shortened, resulting in energy saving.

  The present invention is not limited to the above embodiments, and can be modified without departing from the spirit of the present invention. In addition to the dehumidifier, it can also be applied to various air conditioners.
