Description

  The present invention relates to a dehumidifying dryer for dehumidifying and drying indoor air.

  Conventionally, a dehumidifying dryer using an adsorbent has been proposed. For example, Patent Document 1 includes a dehumidification rotor configured using ceramic paper carrying an adsorbent (hygroscopic material) such as zeolite or silica gel, and sucks air in the bathroom and enters the bathroom via the dehumidification rotor. There is described a dehumidifying dryer (a bathroom heating dryer with a dehumidifying function) having a circulating air path to be returned and a regenerating air path that sucks air in the bathroom and discharges it outside the bathroom via a regenerating heater and a dehumidifying rotor. In this dehumidifying dryer, since the dehumidification rotor is arranged so as to cross each of the circulation air passage and the regeneration air passage, dehumidification in the bathroom by flowing the air in the bathroom to the circulation air passage, The adsorbent can be regenerated at a time by heating the air sucked into the regenerative air passage with the regenerative heater and then sending it to the dehumidifying rotor.

  In Patent Document 2, a refrigerant circuit is configured using two heat exchangers carrying an adsorbent, and the circulation direction of the refrigerant in the refrigerant circuit is configured to be reversible, so that the refrigerant circulation direction is reversed. Thus, each of the two heat exchangers alternately functions as an evaporator and a condenser so that the dehumidification in the room is performed on the evaporator side and the moisture is transferred to the outdoor air on the condenser side. A dehumidifying dryer (humidity control device) that switches the distribution channel is described. In the dehumidifying dryer, the refrigerant circuit is disposed in the casing.

Japanese Patent No. 3804866 Japanese Patent No. 3815485

  However, as in the dehumidifying dryer described in Patent Document 1, it is difficult to reduce the number of parts in a dehumidifying dryer having a regeneration heater and a dehumidification rotor for regenerating the adsorbent separately. In addition, when the dehumidification rotor is disposed so as to cross each of the circulation airflow path and the regeneration airflow path, the two airflows are prevented from mixing the air dehumidified by the dehumidification rotor and the air humidified by the regeneration of the adsorbent. Since the seal structure for dividing the path becomes complicated, it is difficult to reduce the size of the apparatus. Furthermore, since the air heated by the regenerative heater is sent to the dehumidification rotor to regenerate the adsorbent, only a part of the heat energy generated by the regenerative heater is used for regenerating the adsorbent, resulting in a lot of energy waste.

  In addition, since the air for regeneration of the adsorbent is taken into the equipment from the room to be dehumidified (own room), the same amount of air flows into the room from the other room, and when the other room has high humidity, There is a problem that it is affected by the air conditions of other rooms, such as the humidity of the own room increasing.

  In the dehumidifying dryer of Patent Document 2 in which a refrigerant circuit is configured using two heat exchangers carrying an adsorbent and each of these two heat exchangers functions alternately as an evaporator and a condenser, the structure is complicated. Therefore, it is difficult to reduce the size of the apparatus. The adsorbent carried on the heat exchanger is regenerated when the heat exchanger functions as a condenser, but the adsorbent is adsorbed on the adsorbent because the temperature at the time of regeneration is about 60 ° C. at the maximum. It is difficult to sufficiently desorb the moisture, and the regeneration efficiency of the adsorbent is low.

  The present invention has been made in view of the above circumstances, and obtains a dehumidifying dryer that can efficiently regenerate the adsorbent and is not easily affected by the air conditions in the surrounding room and is easy to downsize. For the purpose.

  The dehumidifying dryer of the present invention includes an indoor air inlet for sucking in indoor air, an air inlet for another room for sucking air in another room, an air outlet for blowing out the sucked air into the room, and A housing part provided with an exhaust port for exhausting the sucked air to the outside, and an air outlet that is arranged in the housing part and sucks air into the housing part from at least one of the indoor air suction port and the other room air suction port And a blower for blowing out from at least one of the exhaust ports, a heater disposed between the indoor air suction port and the air outlet in the housing portion, and a dehumidifying adsorbent carried by the heater, The air outlet opening and closing part that opens and closes the air outlet and the air intake path in the blower are connected to the air blower from the indoor air intake passage from the indoor air intake opening to the blower and from the other air intake opening. Intake air path switching unit that can be defined in at least one of the air flow paths in the other rooms, an exhaust port opening / closing part that opens and closes the exhaust port, a blower, a heater, an outlet opening / closing part, an intake air path switching unit, and exhaust A control unit that controls the operation of the opening and closing unit, the control unit, when dehumidifying the room, open the outlet opening and closing unit, the intake air path switching unit to change the intake path in the blower to the indoor air air path, When the blower is operated with the exhaust opening / closing part closed and moisture is desorbed from the adsorbent to regenerate the adsorbent, the heater is operated, and the humid air containing moisture desorbed from the adsorbent by regeneration of the adsorbent is The air outlet can be exhausted to the outside by closing the air outlet opening / closing part and opening the air outlet opening / closing part under the control of the control part and operating the blower.

  In the dehumidifying dryer of the present invention, since the adsorbent is supported on the heater, most of the heat energy generated in the heater can be used for regeneration of the adsorbent. Further, the number of parts is reduced as compared with the case where parts for supporting the adsorbent are provided separately from the heater. Furthermore, since the air path for dehumidification and the air path for exhaust can be formed by opening / closing control of the intake air path switching unit, the air outlet opening / closing unit, and the exhaust port opening / closing unit, the air path in the housing unit. The seal structure can be made relatively simple. Therefore, according to the present invention, it is possible to obtain a dehumidifying dryer which can efficiently regenerate the adsorbent and can be easily miniaturized. In addition, it is configured so that air necessary for draining water after desorption can be taken from another room other than the room to be dehumidified, and the room to be dehumidified can be ventilated when the adsorbent is regenerated. Since it is not, it is hardly affected by the air condition of the surrounding room and can be stably dehumidified.

Hereinafter, components of the dehumidifying dryer 70A will be described individually.

  The housing part 20 (see FIGS. 1 to 3) includes a ventilation duct connection part 3 for other rooms, an exhaust duct connection part 5, and a rectangular parallelepiped housing body 10. Each of the other-room ventilation duct connection portion 3 and the exhaust duct connection portion 5 is attached to a side surface of the housing body 10. The ventilation duct connecting part 3 for the other room is formed with an air inlet 3a for the other room that communicates with the interior of the housing part 20 through the ventilation hole 10d (see FIG. 3) provided on the side surface of the housing body 10, The ventilation duct connecting part 3 for other rooms is connected to a duct communicating with another room (for example, a washroom) different from the room (for example, a bathroom) where the dehumidifying dryer 70A is installed. Further, the exhaust duct connection portion 5 is formed with an exhaust port 5a (see FIG. 1) communicating with the inside of the housing portion 20 through a ventilation port (not shown) provided on the side surface of the housing body 10. The exhaust duct connecting portion 5 is connected to the exhaust duct.

  On the indoor side surface (bottom surface) of the housing body 10, an indoor air inlet 10a for sucking in indoor air, and an air outlet 10b (see FIG. 1) for blowing out the sucked air into the room. A motor shaft insertion opening (not shown) for inserting the rotation shaft of the motor M of the blower 25 is formed on the outdoor surface (upper surface).

  The blower 25 (see FIGS. 1 and 3) is a single-suction sirocco fan blower, which is separated from each of the indoor air inlet 10a, the other-room air inlet 3a, the air outlet 10b, and the exhaust outlet 5a. It is arranged in the part 20. A suction port 25a (see FIG. 1) in the blower 25 faces the indoor air suction port 10a, and the other room air suction port 3a is close to the suction port 25a. Moreover, the blower outlet 25b (refer FIG. 3) of the air blower 25 exists in the heater 30 side, and the motor M (refer FIG. 2 and FIG. 3) is arrange | positioned outside the housing main body 10. FIG.

  For example, the heater 30 (see FIGS. 1 and 3) is arranged around the heat generating element and the heat dissipating fin by arranging a plurality of heat generating elements at intervals or by providing a plurality of heat dissipating fins around the heat generating element. An electric heater configured to radiate heat by forming an air flow path and passing air through the flow path, and a heating element in which an electric insulator and a heat conductor are arranged in the periphery are housed in a metal pipe. An electric heater or the like is used, and an adsorbent such as silica gel or zeolite is supported on the surface thereof. The heater 30 is held by a cylindrical heater holding portion 35 (see FIGS. 1 and 3), and is located above the air outlet 10b (outside of the room) and closer to the exhaust outlet 5a than the outlet 25b of the blower 25. It is arranged below (inside the room). From the viewpoint of suppressing overheating of the heater 30, it is preferable to use a PTC (Positive Temperature Coefficient) heater as the heater 30.

  The air outlet opening / closing part 40A (see FIG. 1) is arranged in the air outlet 10b and opens and closes the air outlet 10b. In the example shown in the figure, the air outlet opening / closing part 40A is constituted by an electric louver having four blades 40a arranged in parallel.

The air passage partition portion 45 (see FIG. 3) includes a first air passage partition portion 42 erected in the housing portion 20 so as to face the air vent 10d formed in the housing body 10, and the air blower 25. It has the 2nd air-path partition part 43 standingly arranged from the blower outlet 25b to the circumference | surroundings of the heater 30. FIG. The air passage partition 45 forms a later-described indoor air air passage FP ₁ between the air suction port 10 a and the blower 25, and the later-described other room air between the other-room air suction port 3 a and the blower 25. Air path FP ₂ is formed. Further, an exhaust chamber ER (see FIG. 3) is defined around the heater 30 and its surroundings. For this purpose, an intake opening (not shown) is formed in the lower part of the first air passage partitioning portion 42 so as to allow the indoor air air passage FP ₁ and the other air air passage FP ₂ to communicate with each other. The second air passage partition 43 is formed with an exhaust opening (not shown) so as to overlap with a ventilation opening (not shown) formed in the housing body 10 and communicating with the exhaust outlet 5a. ing.

The intake air path switching unit (not shown) is configured by, for example, an electric damper, and switches the intake path in the blower 25 to an indoor air air path FP ₁ or another room air air path FP ₂ described later. Specifically, by opening the air suction port 10a and closing the intake opening in the _first air passage partition 42, the air intake passage in the blower 25 is changed to the indoor air air passage FP1, and the air suction is performed. the mouth 10a to the intake path in the blower 25 by the air intake opening of the above open another compartment air air path FP ₂ while closed. The intake air path switching unit will be described in detail later with reference to FIGS.

  The exhaust port opening / closing part 55 (see FIG. 3) is configured by, for example, an electric damper, and opens and closes the exhaust port 5a. In the illustrated dehumidifying dryer 70 </ b> A, an exhaust port opening / closing unit 55 is provided inside the exhaust chamber ER with respect to the second air passage partition unit 43.

  The control unit 60 includes a storage element (not shown) in which a predetermined control program is stored, and the blower 25, the heater 30, and the outlet opening / closing unit 40A according to a command input from a remote controller (not shown). The operations of the intake air path switching unit (not shown) and the exhaust opening / closing unit 55 are separately controlled to cause the dehumidifying dryer 70A to perform a dehumidifying operation, an adsorbent regeneration operation, and the like.

  Hereinafter, the dehumidifying operation and the regenerating operation in the dehumidifying dryer 70A will be described with reference to FIGS. 4 to 7 in addition to FIGS. FIG. 4 is a perspective view schematically showing an internal state from the side when the dehumidifying dryer shown in FIG. 1 is performing a dehumidifying operation. 5 is a perspective view schematically showing the state when the dehumidifying dryer shown in FIG. 1 is performing the regeneration operation from the indoor side, and FIG. 6 is a diagram showing the situation where the dehumidifying dryer shown in FIG. FIG. 7 is a perspective view schematically showing the internal state when the regeneration operation is performed from the side, and FIG. 7 shows the internal state when the dehumidifying dryer shown in FIG. 1 is performing the regeneration operation. It is a perspective view shown roughly from the outside.

In the above dehumidifying operation, as shown in FIGS. 1 and 4, the air outlet 10b is opened by the outlet opening / closing part 40A (hereinafter referred to as “the outlet opening / closing part 40A is opened”), and also shown in FIG. Thus, the exhaust port 5a is closed by the exhaust port opening / closing part 55 (hereinafter referred to as “the exhaust port opening / closing part 55 is closed”). In addition, as shown in FIG. 4, the indoor air intake port 10 a is opened by the intake air passage switching unit 50 and the intake opening 42 a of the first air passage partition 42 is closed. intake path is in the indoor air air path FP _1. Further, the blower 25 is activated. The heater 30 is not energized.

As these results, room air dehumidification dryer 70A is installed flows from the indoor air inlet 10a to the indoor air air path FP _1, it flows from the intake port 25a of the blower 25 to the air blowing unit 25. The air that has flowed into the blower 25 blows out from the blower outlet 25b to the exhaust chamber ER (see FIG. 3) through the internal flow path of the blower 25, passes through the flow passage in the heater 30, and the air blower outlet 10b (FIG. Or, see FIG. 4) to the above room. It does not flow into the exhaust port 5a (see FIG. 3). In the process of passing through the heater 30, moisture in the air is adsorbed on the adsorbent carried on the heater 30, and the air is dehumidified.

On the other hand, in the adsorbent regeneration operation, as shown in FIGS. 5 and 6, the air outlet 10b is closed by the outlet opening / closing part 40A (hereinafter referred to as “the outlet opening / closing part 40A is closed”). Further, the intake air passage switching unit 50 closes the indoor air inlet 10a and the intake opening 42a of the first air passage partition 42 is opened (see FIG. 6). There are other compartment air air path FP _2. Further, the exhaust port 5a is opened by the exhaust port opening / closing unit 55 (hereinafter referred to as “the exhaust port opening / closing unit 55 is opened”), the blower 25 is activated, and energization of the heater 30 is started.

As these results, the air different from the room (other room) flows from the other chamber air inlet 3a to the other compartment air air path FP ₂ is a room dehumidification dryer 70A is installed, the intake opening The air flows into the blower 25 through the air inlet 25a of the blower 25 through 42a. The air that has flowed into the blower 25 passes through the internal flow path of the blower 25 and then blows out from the blower outlet 25b to the exhaust chamber ER. It flows into the exhaust port 5a through, and is exhausted to the outside from here. Further, since the adsorbent (not shown) carried on the heater 30 is heated by the heater 30, moisture is desorbed from the adsorbent and the adsorbent is regenerated. The humid air containing moisture desorbed from the adsorbent is exhausted to the outside through the exhaust port 5a together with the air in the other chamber blown out from the blower 25 to the exhaust chamber ER.

  Therefore, the ventilation operation of the other room is naturally performed during the regeneration operation. Ventilation of the room (own room) in which the dehumidifying dryer 70A is installed is not performed by the dehumidifying dryer 70A. For this reason, it is difficult for the air in the other room to flow into the own room during the regeneration operation and the air condition in the own room, particularly the humidity environment, is changed. Since the room is not ventilated when the adsorbent is regenerated, the room is hardly affected by the air condition of the surrounding room, and the dehumidification of the room is performed stably.

  For example, if a dehumidifying dryer that sucks in the air necessary for discharging moisture desorbed from the adsorbent is installed in the bathroom, the same amount of air as when the moisture is discharged will be discharged from the bathroom door galley, etc. If the air in the bathroom is ventilated and the humidity of the air entering from the louver is high, the humidity in the bathroom will increase, etc. According to the dryer 70A, the air in the other room is taken into the equipment through the duct and the moisture is discharged, so that the interior of the bathroom is not ventilated and is not easily affected by the air condition of the surrounding room, and is stable. And can be dehumidified.

  The temperature of the heater 30 during the regeneration operation can be appropriately selected according to the type of adsorbent carried on the heater 30. For example, when silica gel is used as the adsorbent, moisture can be sufficiently desorbed from the silica gel even when the temperature of the heater 30 is relatively low (for example, about 60 ° C. to 100 ° C.) and the regeneration operation is performed. Can do. On the other hand, when zeolite is used as the adsorbent, the zeolite is an adsorbent suitable for drying indoors and objects to be dried, but in order to desorb the moisture once adsorbed, it is better than regenerating silica gel. However, it is necessary to heat the heater 30 at a relatively high temperature during the regeneration operation.

  In addition, the timing of the regeneration operation can be selected as appropriate. For example, the regeneration operation may be performed after the dehumidification operation has been performed for a long time and the adsorption capacity of the adsorbent has greatly decreased, or the regeneration is performed when the dehumidification operation is performed for a relatively short time and the adsorption capacity of the adsorbent is still high You may drive. In addition, when a large heater cannot be used as the heater 30 because the installation space is small, a small heater may be used. When a small heater 30 is used, the amount of adsorbent that can be carried on the heater 30 is reduced, so that the moisture adsorption and dehumidification speed is slow, but dehumidification and regeneration are repeated in a short cycle. As a result, although it takes time, a desired dehumidifying amount can be ensured, so that the dehumidifying dryer 70A can be easily downsized. At the time of the dehumidifying operation performed following the regeneration operation, the heat generated in the heater 30 during the regeneration operation is input into the own room by blowing air, and the temperature of the own room rises. When the dryer 70A is used as a bathroom dryer, a dryer for a room to be dried, etc., drying is performed efficiently.

  If necessary, a cooling operation for cooling the heater 30 may be performed following the regeneration operation. For example, the cooling operation can be performed in the same manner as the regeneration operation except that the heater 30 is not energized.

  In the dehumidifying dryer 70A that performs the dehumidifying operation and the adsorbent regeneration operation as described above, since the adsorbent is carried by the heater 30, most of the thermal energy generated in the heater 30 is regenerated. Can be used. Further, the number of parts is reduced as compared with the case where the parts for supporting the adsorbent are parts different from the heater 30. Furthermore, since the dehumidifying air passage and the exhaust air passage can be formed by opening / closing control of the air outlet opening / closing portion 40A, the intake air passage switching portion 50, and the exhaust opening / closing portion 55, the housing portion 20 can be formed. The sealing structure of the air passage inside can be made relatively simple. Therefore, in the dehumidifying dryer 70A, the adsorbent can be efficiently regenerated and the size can be easily reduced.

  Increased efficiency of adsorbent regeneration leads to a reduction in energy consumption, and reduction in the number of parts results in workability when disassembling the dehumidifying dryer 70A for disposal and workability when separating materials after disassembly. Leads to improvement. Further, the miniaturization of the dehumidifying dryer 70A leads to a reduction in packaging at the time of packaging, efficiency of transportation during distribution, improvement of collection and transportability at the time of disposal, and reduction of an environmental load at the time of disposal.

Note that the regeneration operation can also be performed by setting the intake air path in the blower 25 to the indoor air air path FP ₁ by the intake air path switching unit 50. Further, the regeneration operation can be performed by setting the intake air path in the blower 25 to both the indoor air air path FP ₁ and the other room air air path FP ₂ by the intake air path switching unit 50.

In addition, the dehumidifying dryer 70A can perform heating operation, ventilation operation, drying operation, ventilation operation of other rooms, etc. in the room where the dehumidifying dryer 70A is installed. The heating operation of the room in which the dehumidifying dryer 70A is installed is performed in the same manner as the dehumidifying operation described above except that the heater 30 is energized. In the ventilation operation of the room where the dehumidifying dryer 70A is installed, the heater 30 is not energized, and the intake air path in the blower 25 is changed to the indoor air air path FP ₁ by the intake air path switching unit 50. Except for each, it is performed in the same manner as the regeneration operation described above.

Drying operation room dehumidifying dryer 70A is installed, to that to the indoor air air path FP ₁ intake path in the blower 25 by the intake air passage switching unit 50, and the air outlet opening and closing unit 40A in the open Except for the above points, the above-described regeneration operation is performed. For example, if the dehumidifying dryer 70A is installed in a bathroom and a drying operation is performed, the dehumidifying dryer 70A is used as a conventional hot air dryer that performs ventilation while blowing hot air to dry the bathroom and clothes. You can also In the ventilation operation of another room (other room) different from the room where the dehumidifying dryer 70A is installed, the intake air path in the blower 25 is changed to the other room air air path FP ₂ by the intake air path switching unit 50. The dehumidifying operation can be performed in the same manner as described above except that the air outlet opening / closing part 40A is closed and the air outlet opening / closing part 55 is opened.

Embodiment 2. FIG.
In the dehumidifying dryer according to the present invention, the air state of the room (own room) where the dehumidifying dryer is installed and other rooms (other rooms), specifically, humidity and temperature are detected, and during dehumidifying operation and It can also be configured such that the control unit selects the control content of at least one of the regeneration operations. Thus, when comprising a dehumidification dryer, the sensing part for detecting the state of the said air is arrange | positioned in the vicinity of the inlet of a blower, for example.

  FIG. 8 is a perspective view schematically showing the inside of an example of a dehumidifying dryer provided with a sensing unit that detects the air state of the own room or the other room from the side. In the dehumidifying dryer 70B shown in the figure, the sensing unit 63 for detecting the humidity and temperature of the air in the room (own room) in which the dehumidifying dryer 70B is installed and other rooms (other rooms) It arrange | positions in the vicinity of the suction inlet 25a. The control unit (not shown in FIG. 8) selects the control content of at least one of the dehumidifying operation and the regenerating operation according to the detection result of the sensing unit 63.

  The configuration of the dehumidifying dryer 70B includes the sensing unit 63, and the control unit selects the control content according to the detection result of the sensing unit 63 when performing at least one of the dehumidifying operation and the regeneration operation. Except for each point, for example, the same configuration as the dehumidifying dryer 70A described in the first embodiment can be used. Constituent members other than the sensing unit 63 shown in FIG. 8 are denoted by the same reference numerals as those used in FIG.

  For example, when the humidity of the room where the dehumidifying dryer 70B is installed is high, the amount of moisture adsorbed per unit time by the adsorbent (not shown) carried on the heater 30 increases. Even if the dehumidifying operation time is shortened, the amount of moisture adsorbed by the adsorbent increases. If the amount of moisture adsorbed by the adsorbent is large, more heat energy is required to desorb moisture from the adsorbent in the regeneration operation. On the other hand, when the humidity of the room in which the dehumidifying dryer 70B is installed is low, the amount of moisture adsorbed per unit time by the adsorbent is reduced. If the amount of moisture adsorbed by the adsorbent is small, the thermal energy required to desorb moisture from the adsorbent in the regeneration operation is also reduced.

  Therefore, when the above-described sensing unit 63 is configured by a humidity sensor, the control unit detects that a humidity (relative humidity) equal to or higher than a predetermined first condition value is detected by the sensing unit 63 (humidity sensor) during the dehumidifying operation. In addition, the duration of one regeneration operation relative to the duration of one dehumidifying operation is relatively longer than when the detection result of the sensing unit 63 is less than the first condition value, or a heater is used during the regeneration operation. Increase the amount of power input to 30.

  The first condition value is determined by the manufacturer of the dehumidifying dryer 70B and is stored in advance in, for example, a storage element (not shown) in the control unit. There may be only one first condition value, or two or more different values. Further, for each of the detection result of the sensing unit 63 being equal to or greater than the first condition value and less than the first condition value, the duration of one dehumidifying operation and the duration of one regeneration operation The amount of electric power supplied to the heater 30 during the regeneration operation is determined for each condition value by the manufacturer of the dehumidifying dryer 70B, and data for managing them by a method such as table management is stored in the storage element in advance. Is done.

  The control unit uses the first condition value and data stored in the storage element and the detection result of the sensing unit 63 to control at least one of the dehumidifying operation and the regeneration operation, specifically, The operation contents of the blower 25 and the heater 30 are selected, and the blower 25 and the heater 30 are controlled under the selected control contents to operate the dehumidifying dryer 70B. When the dehumidifying dryer 70 </ b> B is configured such that the control unit selects only the control content of one of the dehumidifying operation and the regeneration operation according to the detection result of the sensing unit 63, the other control content is the sensing unit 63. Regardless of the detection result, for example, the control content is preset by the manufacturer of the dehumidifying dryer 70B.

  When the dehumidifying operation and the regeneration operation are alternately performed under the control of the control unit, the sensing unit 63 can be configured by a temperature sensor. In this case, the remaining heat of the heater 30 is input into the room during the dehumidifying operation after the regeneration operation, and the temperature of the room gradually increases according to the degree of drying and humidity of the object to be dried. ) Based on the detection result, the control unit calculates the degree of the temperature rise, and based on the result, the control content of at least one of the dehumidifying operation and the regeneration operation, specifically, the blower 25 and the heater 30 The dehumidifying dryer 70B can be configured to select the operation content.

  That is, if the degree of temperature rise is less than a predetermined value (hereinafter referred to as “second condition value”), it is considered that the degree of drying of the indoor objects to be dried is low and the humidity is high. If the degree is equal to or greater than the second condition value, it is considered that the degree of drying of the indoor object to be dried is high and the humidity is low. For example, in the same manner as when the sensing part 63 is configured by a humidity sensor, the sensing part 63 (temperature The dehumidifying dryer 70B can be configured so that the control unit selects the control content of at least one of the dehumidifying operation and the regenerating operation according to the detection result of the sensor. The second condition value is determined by the manufacturer of the dehumidifying dryer 70B and is stored in advance, for example, in a storage element (not shown) in the control unit. There may be only one second condition value, or two or more different values.

  When the sensing unit 63 is configured by the humidity sensor and the temperature sensor, the control unit obtains the indoor absolute humidity from the detection results of these sensors, and the control unit performs the dehumidifying operation and the regeneration operation according to the absolute humidity. The dehumidifying dryer 70B can be configured to select the control content of at least one of these, specifically, the operation content of the blower 25 and the heater 30. In this case, data for obtaining the absolute humidity from the detection result of the humidity sensor and the detection result of the temperature sensor is stored in advance in a storage element (not shown) in the control unit, for example. Selection of the control content can be performed in the same manner as when the sensing unit 63 is configured by only the humidity sensor.

Further, the control unit determines whether the intake air path in the blower 25 during the regeneration operation is the indoor air air path FP ₁ or the other room air air path FP ₂ based on the detection result of the sensing unit 63, and the temperature is The control unit can also be configured to control the operation of the intake air path switching unit 50 so that air suitable for regeneration of the adsorbent, such as high or low humidity, is sucked into the blower 25.

In this case, the temperature when the control unit controls the operation of the intake air path switching unit 50 before the start of the regeneration operation or at the initial stage of the regeneration operation to change the intake path in the blower 25 to the indoor air air path FP _1. humidity, and the temperature and humidity at which the intake passage and the other chamber air air path FP ₂ in blower 25 respectively is detected in the sensing unit 63. Then, the control unit controls the operation of the intake air path switching unit 50 based on the detection result of the sensing unit 63 so that air suitable for regeneration of the adsorbent flows into the blower 25.

Of course, the air intake path in the blower 25 does not have to be one of the indoor air air path FP ₁ and the other room air air path FP ₂ , but the indoor air air path FP ₁ and the other room air air path FP. it is also possible to both _2. Further, the temperature and humidity of other chambers of the air only when the air inlet path in the blower 25 in the other compartment air air path FP ₂ detected by the sensing unit 63, it is determined that air in the other chamber is not suitable for regeneration operation when the may constitute the dehumidifying and drying apparatus 70B so as to select the temperature and humidity of the air in his room to room air wind passage FP ₁ intake path in the blower 25 without detecting the sensing unit 63. Note that the criterion for determining whether the air is suitable for the regeneration operation is determined by the manufacturer of the dehumidifying dryer 70B, and is stored in advance in, for example, a storage element in the control unit.

  In the dehumidifying dryer 70B configured as described above, during the dehumidifying operation and the regeneration operation, depending on the air state of the room (own room) where the dehumidifying dryer 70B is installed or the other room (other room). Since at least one of the operating conditions can be set to an appropriate condition, useless energy consumption can be suppressed. Even if the relative humidity is the same value, the amount of moisture per unit volume in the air varies depending on the temperature, and as a result, the amount of moisture adsorbed by the adsorbent also changes, so from the viewpoint of suppressing wasteful energy consumption The humidity sensor and the temperature sensor constitute the sensing unit 63, and the control unit selects the control contents at least during the dehumidifying operation and the regeneration operation according to the absolute humidity of the room obtained from the detection results of these sensors. Thus, it is preferable to configure the dehumidifying dryer 70B.

Embodiment 3 FIG.
The dehumidifying dryer of the present invention can also be configured to regenerate the adsorbent while suppressing the generation of airflow around the heater. Such a dehumidifying dryer is described in, for example, the dehumidifying dryer 70A (see FIGS. 1 to 7) described in the first embodiment and the second embodiment, except that the control content of the control unit at the time of adsorbent regeneration is changed. The same dehumidifying dryer 70B (see FIG. 8) can be configured.

FIG. 9 is a schematic diagram showing a state during regeneration of the adsorbent in an example of a dehumidifying dryer configured to regenerate the adsorbent in a state where generation of airflow around the heater is suppressed. The dehumidifying dryer 70C shown in the figure closes each of the outlet opening / closing part 40A and the exhaust opening / closing part 55 and stops the blower 25 to regenerate the adsorbent. The air intake path in the blower 25 may be the indoor air air path FP ₁ or the other room air air path FP ₂ (see FIG. 6). When the adsorbent is regenerated in this way, the generation of airflow around the heater 30 including the occurrence of natural convection accompanying the temperature rise of the heater 30 is suppressed while the adsorbent is regenerated. It is done. Thereafter, the exhaust port opening / closing part 55 is opened, the blower 25 is activated, and the humid air generated by the regeneration of the adsorbent is exhausted from the exhaust port 5a to the outside.

FIG. 10 is a schematic diagram showing a state during regeneration of the adsorbent in another example of the dehumidifying dryer configured to regenerate the adsorbent while suppressing the generation of airflow around the heater. The dehumidifying dryer 70D shown in the figure closes the outlet opening / closing part 40A, opens the outlet opening / closing part 55, stops the blower 25, and regenerates the adsorbent. The air intake path in the blower 25 may be the indoor air air path FP ₁ or the other room air air path FP ₂ (see FIG. 6). Even if the adsorbent is regenerated in this way, the generation of airflow around the heater 30 is suppressed while the adsorbent is being regenerated. Thereafter, the blower 25 is activated to exhaust the humid air generated by the regeneration of the adsorbent to the outside through the exhaust port 5a.

  The dehumidifying dryers 70C and 70D have the same configuration as the dehumidifying dryer 70A described in the first embodiment except that the control content of the control unit at the time of adsorbent regeneration is different. The constituent members shown in FIG. 9 or FIG. 10 are given the same reference numerals as those used in FIG. 1 to FIG. Reference symbol “F” in FIGS. 9 and 10 indicates the sirocco fan of the blower 25, and the wavy arrow indicated by the reference symbol “V” schematically represents water vapor due to moisture desorbed from the adsorbent (not shown). Is shown. Reference symbol “S” indicates a space in which humid air containing moisture desorbed from the adsorbent can stay, and the space corresponds to an upper space in the exhaust chamber ER.

  When the adsorbent is regenerated while suppressing the generation of airflow around the heater 30 as described above, the temperature drop of the heater 30 due to heat dissipation can be suppressed. Further, since the moisture desorbed from the adsorbent becomes water vapor and stays in the space S above the heater 30, the water vapor stays in the vicinity of the heater 30 and hinders the desorption of moisture from the adsorbent. It is hard to happen.

  Therefore, in each of the dehumidifying dryers 70C and 70B described above, the adsorbent can be sufficiently heated to desorb moisture from the adsorbent even if the amount of power input to the heater 30 is relatively small. It is possible to efficiently regenerate the adsorbent. For example, when an adsorbent having a high adsorbing capacity even in a low humidity environment such as zeolite is supported on the heater 30, heating at a high temperature is necessary to sufficiently regenerate such an adsorbent. The dehumidifying dryers 70C and 70D that can sufficiently heat the adsorbent even if the amount of power input to the heater 30 is relatively small are suitable from the viewpoint of reducing energy consumption.

  Further, since the adsorbent is regenerated while the blower 25 is stopped, the air in the room is not ventilated by the dehumidifying dryers 70C and 70D during the regeneration of the adsorbent. For this reason, it is difficult for the outdoor air to flow into the room in which the dehumidifying dryers 70C and 70D are installed and the humidity in the room rises, and the dehumidifying operation and the regenerating operation are repeated. Dehumidification and drying can be carried out efficiently when conditioning the air in the room.

  Even if the adsorbent is regenerated by opening the air outlet opening / closing unit 40A, closing the exhaust port opening / closing unit 55, and stopping the blower 25, while the adsorbent is being regenerated, The generation of airflow at is suppressed. In addition, in a dehumidifying dryer in which the regeneration operation interval is set long or a large amount of adsorbent is supported on the heater 30, a relatively large amount of moisture is desorbed during one adsorbent regeneration, The exhaust opening / closing part 55 is opened temporarily during the regeneration operation or always during the regeneration operation, or the exhaust opening / closing part 55 is opened and the blower 25 is activated to remove the humidified moisture. You may comprise so that air may be exhausted outside from the exhaust port 5a (refer FIG. 9 or FIG. 10).

Embodiment 4 FIG.
In the dehumidifying dryer of the present invention, the temperature of the heater can be detected by a temperature sensor, and the amount of electric power supplied to the heater 30 can be controlled according to the detected temperature. Such a dehumidifying dryer is the same as the dehumidifying dryer described in the first embodiment except for the presence / absence of the temperature sensor and the control content of the control unit during the regeneration operation (control related to the amount of electric power supplied to the heater 30). 70A (see FIGS. 1 to 7), the dehumidifying dryer 70B (see FIG. 8) described in the second embodiment, or the dehumidifying dryers 70C and 70D (see FIG. 9 or FIG. 10) described in the third embodiment. It can be configured similarly.

  FIG. 11 is a schematic diagram illustrating an example of a dehumidifying dryer provided with a temperature sensor that detects the temperature of the heater. The dehumidifying dryer 70E shown in the figure has a temperature sensor 65 for detecting the temperature of the heater 30, and a controller (not shown) monitors the temperature detected by the temperature sensor 65 during the regeneration operation. The amount of electric power supplied to the heater 30 is controlled according to the detected temperature. Specifically, when the temperature detected by the temperature sensor 65 reaches a preset temperature (hereinafter referred to as “third condition value”), the amount of electric power supplied to the heater 30 is reduced, or Stop energization.

  The dehumidifying dryer 70E has the same configuration as the dehumidifying dryers 70C and 70D described in the third embodiment except for the presence / absence of the temperature sensor 65 and the control contents of the control unit during the regeneration operation. The constituent members shown in FIG. 11 are denoted by the same reference numerals as those used in FIG. 9 or FIG.

  The third condition value is a temperature at which moisture can be sufficiently desorbed from the adsorbent (not shown), and depends on the type and amount of the adsorbent (not shown) carried on the heater 30. It is set by the manufacturer of the dehumidifying dryer 70E and stored in advance in a storage element (not shown) in the control unit, for example. The control unit reduces the amount of electric power supplied to the heater 30 when the temperature detected by the temperature sensor 65 is equal to or higher than the third condition value, and sets the temperature of the heater 30 over a predetermined time for the third time. The temperature is maintained at or near the condition value, the amount of electric power supplied to the heater 30 is gradually decreased to gradually decrease the temperature of the heater 30, or the energization to the heater 30 is stopped and the heater is stopped. Let 30 cool naturally.

  In the dehumidifying dryer 70E configured as described above, it is possible to suppress heating of the adsorbent more than necessary during the regeneration operation, and thus wasteful energy consumption can be suppressed. Although various types of heaters can be used as the heater 30, if the PTC heater described in the first embodiment is used, overheating of the heater 30 can be prevented and wasteful energy consumption can be easily suppressed.

Embodiment 5 FIG.
In the dehumidifying dryer of the present invention, the air blowing direction from the air outlet can be configured to be variable. For example, when the air outlet louver 40A (see FIG. 1) is configured using an electric louver having a plurality of blades 40a arranged in parallel as in the dehumidifying dryer 70A described in the first embodiment. Is configured such that the opening degree of the slats 40a can be changed continuously or stepwise by the control unit, so that the dehumidifying drying in which the air blowing direction from the air outlet 10b (see FIG. 1) is variable is possible. A machine is obtained. Moreover, a dehumidifying dryer in which the air blowing direction from the air blowing port is variable can also be obtained by configuring the blowing port opening / closing unit using an electric louver in which a plurality of slats are arranged vertically and horizontally.

  FIG. 12 is a perspective view schematically showing an example of the dehumidifying dryer in which the air blowing direction from the air outlet is variable. The dehumidifying dryer 70F shown in the figure has the same configuration as the dehumidifying dryer 70A shown in FIG. 1 except that it includes an outlet opening / closing part 40B instead of the outlet opening / closing part 40A shown in FIG. have. Of the constituent members shown in FIG. 12, those common to the constituent members shown in FIG. 1 are assigned the same reference numerals as those used in FIG.

  The air outlet opening / closing section 40B includes four wing plates 40a arranged in parallel and four wing plates arranged in parallel in a direction intersecting with the wing plate 40a when viewed in plan, specifically in a direction perpendicular to the wing plate 40a. An electric louver having a plate 40b is used. In this air outlet opening / closing section 40B, the opening degree of each slat 40a, 40b can be controlled continuously or stepwise under the control of the control section (not shown in FIG. 12). Therefore, in the dehumidifying dryer 70F, the air blowing direction from the air outlet 10b is variable.

  In the dehumidifying dryer 70F configured in this way, for example, when there is an object to be dried in the room where the dehumidifying dryer 70F is installed, the blowing direction of air from the air outlet 10b is changed continuously or stepwise. Accordingly, it is possible to suppress the occurrence of drying unevenness in the object to be dried by uniformly applying the air after dehumidification to the object to be dried.

Embodiment 6 FIG.

Such a dehumidifying dryer connects, for example, an air duct for other chambers to the exhaust duct connecting portion in each dehumidifying dryer described in the first to fifth embodiments, and generates humid air generated during regeneration of the adsorbent. It is obtained by flowing from the exhaust port to the above-mentioned air supply duct. In addition, the air supply duct connecting part for the other room having the humid air outlet for supplying the humid air to the other room is added to the housing part, and the humid air for opening and closing the humid air outlet under the control of the control part It can also be obtained by providing a wind path opening / closing section and allowing the user to select either or both of supply of humid air to the other room and exhaust of humid air from the exhaust port from the remote controller.

  The humid air airway opening / closing part and the exhaust port opening / closing part can be separate members. Further, when the humid air outlet and the exhaust port are provided close to each other, it becomes possible to open and close the humid air outlet and the exhaust port by a single air passage opening / closing portion constituted by a damper or the like. Therefore, the air path opening / closing part for humid air and the exhaust port opening / closing part can be constituted by one air path opening / closing part. The remaining configuration excluding the presence / absence of the humid air outlet, the presence / absence of the air passage opening / closing unit for the humid air, and the control content of the control unit during exhaust of the humid air is, for example, the dehumidifying dryer described in the first to fifth embodiments It can be set as the structure similar to in FIG.
