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.

  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.

  Moreover, in the dehumidification dryer of patent document 2 which comprises a refrigerant circuit using two heat exchangers which carry | supported adsorption agent, and each of these two heat exchangers functions as an evaporator and a condenser alternately, Is complicated, 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 an object of the present invention is to obtain a dehumidifying dryer that can efficiently regenerate the adsorbent and can be easily downsized.

The dehumidifying dryer of the present invention includes an indoor air inlet for sucking indoor air, an air outlet for blowing the sucked air into the room, and air sucked to remove moisture adsorbed on the adsorbent. A housing part provided with an exhaust port for exhausting the air, and the housing part, the air is sucked into the housing part from the indoor air suction port and blown out from at least one of the air outlet and the exhaust port and one blower for, and arranged heater between the indoor air inlet and the air outlet in said housing portion, said adsorbent for dehumidification carried on the heating device, wherein An air outlet opening and closing portion for opening and closing an air outlet, an air outlet opening and closing portion for opening and closing the air outlet, and the blower, the heater, the air outlet opening and closing portion, and the air outlet opening and closing portion. A control unit that controls the operation, and when the dehumidifying the room, the control unit opens the outlet opening / closing unit and closes the exhaust port opening / closing unit to operate the blower, and When the moisture is desorbed from the adsorbent and the adsorbent is regenerated, the heater is operated. When the humid air containing moisture desorbed from the adsorbent due to regeneration of the adsorbent is exhausted to the outside, the air outlet opening and closing And closing the exhaust port opening and closing unit and operating the blower to regenerate the adsorbent, closing at least one of the outlet opening and closing unit and the exhaust port opening and closing unit, When the agent is regenerated, the blower is stopped, the housing part has a hollow rectangular parallelepiped shape, and the indoor air inlet and the air outlet are provided on the first surface of the housing part. , The exhaust port, of the surface in contact with the first surface of the housing portion, wherein the air outlet is provided on the second surface of the provided side.

  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. Further, since the dehumidifying air passage and the exhaust air passage can be formed by opening / closing control of the air outlet opening / closing portion and the exhaust opening / closing portion, the sealing structure of the air passage in the housing portion is relatively simple. can do. 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.

The exhaust duct connection portion 5 has an exhaust port 5a (see FIG. 1) that communicates with the interior of the housing body 10A through a ventilation port (not shown) provided on the side surface of the housing body 10A, and is connected to the exhaust duct. The A motor shaft insertion port 10a (see FIG. 2) for inserting the rotation shaft of the motor M of the blower 25 is formed on the upper surface of the housing body 10A.

  The partition plate 15 is disposed on the open end side (indoor side) of the housing main body 10A to partition the inside of the housing main body 10A from the outside. The partition plate 15 has an indoor air inlet for sucking in indoor air. 15a is formed. Further, the partition plate 15 is provided with a holding portion insertion port 15b (see FIG. 1) for holding the heater holding portion 17. The heater holding part 17 is a cylindrical body that holds the heater 30, and one end side is fixed to the partition plate 15 side and protrudes from the holding part insertion port 15 b to the outside. The free end (protruding end) side of the heater holding part 17 is an air outlet 17a.

  The blower 25 (see FIGS. 1 and 3) is a single-suction sirocco fan blower, and the housing portion 20A is such that the suction port 25a (see FIG. 1) in the blower 25 is connected to the air suction port 15a. Is placed inside. The blower outlet 25b (see FIG. 3) of the blower 25 is on the heater 30 side, and the motor M (see FIG. 2) is disposed outside the housing body 10A.

  The heater 30 (see FIG. 1 and FIG. 3) includes, for example, a plurality of heat generating elements arranged at intervals, or a plurality of heat dissipating fins provided around the heat generating elements so that the surroundings of the heat generating elements and the heat dissipating fins In the metal pipe, an electric heater configured to dissipate heat by forming an air flow path in the air flow path, and a heat generating element in which an electric insulator and a heat conductor are arranged in the periphery are disposed in the metal pipe. It is configured using a stored electric heater or the like, and an adsorbent such as silica gel or zeolite is supported on the surface thereof. The heater 30 is held by the heater holding portion 17 (see FIGS. 1 and 3) described above, and is disposed below the exhaust port 5a side of the blower outlet 25b of the blower 25. 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 at the indoor side end part of the heater holding part 17, and is the indoor side opening part of the heater holding part 17, that is, the air in the dehumidifying dryer 70A. Open and close the outlet 17a. 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 45 </ b> A (see FIG. 3) is provided upright from the blower outlet 25 b of the blower 25 to the periphery of the heater 30. The air passage partition 45A defines an exhaust chamber ER (see FIG. 3) around the heater 30 and its surroundings. The air passage partition 45A is formed with an exhaust opening (not shown) so as to overlap with a vent (not shown) formed in the housing body 10A and communicating with the exhaust 5a. .

  The exhaust port opening / closing part 50A (see FIG. 3) is constituted by, for example, an electric damper, and opens and closes the exhaust port 5a. In the illustrated dehumidifying dryer 70A, an exhaust opening / closing portion 50A is provided inside the exhaust chamber ER from the air passage partition 45A, and the exhaust opening / closing portion 50A is formed in the air passage partition 45A. The exhaust opening 5a is opened and closed by opening and closing the exhaust opening.

  The control unit 60A 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). And the operation of the exhaust opening / closing unit 50A 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 and 5 in addition to FIGS. 4 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. 5 is a diagram showing the regeneration operation of the dehumidifying dryer shown in FIG. It is a perspective view which shows the state of the inside when performing performing from the outdoor side schematically.

  In the above dehumidifying operation, as shown in FIG. 1, the air outlet 17a is opened by the outlet opening / closing part 40A (hereinafter referred to as “the outlet opening / closing part 40A is opened”) and exhausted as shown in FIG. The port 5a is closed by the exhaust port opening / closing part 50A (hereinafter referred to as “the exhaust port opening / closing part 50A is closed”). Moreover, the air blower 25 is started. The heater 30 is not energized.

  As a result, the air in the room where the dehumidifying dryer 70A is installed flows into the blower 25 through the air suction port 15a and the suction port 25a of the blower 25 (see FIG. 1), and the internal flow path of the blower 25 After passing through the blower outlet 25b to the exhaust chamber ER (see FIG. 3), it blows out from the air blower outlet 17a (see FIG. 1) to the above room through the flow path in the heater 30. 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, the air outlet 17a is closed by the outlet opening / closing part 40A (hereinafter referred to as “the outlet opening / closing part 40A is closed”) as shown in FIG. Thus, the exhaust port 5a is opened by the exhaust port opening / closing part 55 (hereinafter referred to as “the exhaust port opening / closing part 55 is open”). Further, the blower 25 is activated and energization of the heater 30 is started.

  As a result, the air in the room where the dehumidifying dryer 70A is installed flows into the blower 25 through the air suction port 15a and the suction port 25a of the blower 25 (see FIG. 1), and the internal flow path of the blower 25 After passing through the blower outlet 25b to the exhaust chamber ER (see FIG. 3), the exhaust port passes through the exhaust opening 45a (see FIG. 5) of the air passage partition 45 and the vent hole 10b of the housing body 10A. It flows into 5a and is exhausted outside. 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 blown from the blower 25 to the exhaust chamber ER.

  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 is performed for a long time and the adsorption capacity of the adsorbent is greatly reduced, or the dehumidification operation is performed for a relatively short time and the adsorption capacity of the adsorbent is not so decreased. Sometimes regeneration operation may be performed. 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, heat generated in the heater 30 during the regeneration operation is input into the above-described room by blowing air, and the temperature of the room rises. When the dehumidifying dryer 70A is used as a bathroom dryer or the like, the material to be dried is efficiently dried.

  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 and the exhaust opening opening / closing portion 50A, the sealing structure of the air passage in the housing portion 20 is provided. It can be 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.

  It should be noted that the dehumidifying dryer 70A can perform heating operation, ventilation operation, drying operation, etc. of 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. The ventilation operation of the room in which the dehumidifying dryer 70A is installed is performed in the same manner as the above-described regeneration operation except that the heater 30 is not energized. Then, the drying operation of the room in which the dehumidifying dryer 70A is installed is performed in the same manner as the above-described regeneration operation except that the air outlet opening / closing part 40A is opened. 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

Embodiment 2. 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 can be configured in the same manner as the dehumidifying dryer 70A (see FIGS. 1 to 5) described in the first embodiment, for example, except that the control content of the control unit during the regeneration operation is changed. it can.

  FIG. 6 is a schematic diagram showing a state at the time of adsorbent regeneration 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 70B shown in the figure closes each of the outlet opening / closing part 40A and the exhaust opening / closing part 50A under the control of the control part 60B and stops the blower 25 to regenerate the adsorbent. When the adsorbent is regenerated in this way, the generation of air current around the heater 30 including the occurrence of natural convection accompanying the temperature rise of the heater 30 is suppressed during the regeneration. Thereafter, the exhaust port opening / closing part 50A is opened and the blower 25 is activated to exhaust the humid air generated by the regeneration of the adsorbent to the outside from the exhaust port 5a.

  FIG. 7 is a schematic diagram showing a state during regeneration of the adsorbent in another example of the 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 the outlet opening / closing unit 40A, opens the exhaust port opening / closing unit 50A, stops the blower 25, and regenerates the adsorbent under the control of the control unit 60C. Even when the adsorbent is regenerated in this way, the generation of airflow around the heater 30 can be suppressed during the regeneration. 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 70B and 70C have the same configuration as the dehumidifying dryer 70A described in the first embodiment except that the control content of the control unit is different during the regeneration operation. Or about each structural member shown in FIG. 7, the same referential mark as the referential mark used in FIGS. 1-5 is attached | subjected, and the description is abbreviate | omitted. Reference sign “F” in FIGS. 6 and 7 indicates a sirocco fan of the blower 25. 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 70B and 70C described above, the adsorbent can be sufficiently heated to desorb moisture from the adsorbent even if the amount of electric power supplied 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 70B and 70C that can sufficiently heat the adsorbent even if the amount of electric power supplied 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 70B and 70C during the regeneration of the adsorbent. For this reason, it is difficult for the outdoor air to flow into the room where the dehumidifying dryers 70B and 70C are installed and the humidity in the room rises, and it is unlikely that the adsorbent is being regenerated. Dehumidification and drying can be carried out efficiently when the room air is conditioned.

  Even if the blower outlet opening / closing part 40A is opened, the exhaust outlet opening / closing part 50A is closed, the blower 25 is stopped, and the adsorbent is regenerated, the air flow around the heater 30 is maintained during the regeneration. Occurrence 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, During the regeneration operation, or constantly during the regeneration operation, the exhaust port opening / closing part 50A is opened, or the exhaust port opening / closing part 50A is opened and the blower 25 is activated, so You may comprise so that air may be exhausted outside from the exhaust port 5a (refer FIG. 6 or FIG. 7).

Embodiment 3 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, for example, the dehumidifying device described in the first embodiment except for the presence / absence of the temperature sensor and the control content of the control unit at the time of the regeneration operation (control related to the amount of power input to the heater 30) It can be configured in the same manner as the dryer 70A (see FIGS. 1 to 7) and the dehumidifying dryers 70B and 70C (see FIG. 6 or FIG. 7) described in the second embodiment.

  FIG. 8 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 70D shown in the figure has a temperature sensor 63 that detects the temperature of the heater 30. During the regeneration operation, the control unit 60D monitors the temperature detected by the temperature sensor 63 to obtain the detected temperature. Accordingly, the amount of power input to the heater 30 is controlled. Specifically, when the temperature detected by the temperature sensor 63 reaches a preset temperature (hereinafter referred to as “first condition value”), the amount of electric power supplied to the heater 30 is reduced or the electric power supplied to the heater 30 is reduced. Stop energization.

  Since the dehumidifying dryer 70D has the same configuration as the dehumidifying dryers 70B and 70C described in the second embodiment except for the presence / absence of the temperature sensor 63 and the control content of the control unit 60D during the regeneration operation, respectively. The constituent members shown in FIG. 8 are denoted by the same reference symbols as those used in FIG. 6 or FIG.

  The first 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 70D and stored in advance in a storage element (not shown) in the control unit 60D, for example. The controller 60D reduces the amount of electric power supplied to the heater 30 when the temperature detected by the temperature sensor 63 is equal to or higher than the first condition value, and sets the temperature of the heater 30 over a predetermined time. 1 The temperature is maintained at or near the condition value, or the temperature of the heater 30 is gradually decreased by gradually reducing the amount of electric power supplied to the heater 30, or the energization to the heater 30 is stopped and heating is performed. The vessel 30 is allowed to cool naturally.

  In the dehumidifying dryer 70 </ b> D configured in this way, it is possible to suppress heating 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 4 FIG.
In the dehumidifying dryer of the present invention, the state of the air in the room (own room) in which the dehumidifying dryer is installed, specifically, the humidity and temperature are detected, and at least one of the dehumidifying operation and the regeneration operation is detected. The control content can also be configured to be selected by the control unit. Thus, when comprising a dehumidification dryer, the sensing part for detecting the state of the said air is arrange | positioned in the vicinity of an air inlet, for example.

  FIG. 9 is a perspective view schematically showing an example of a dehumidifying dryer provided with a sensing unit that detects the state of air in the room from the indoor side. In the dehumidifying dryer 70E shown in the figure, a sensing unit 65 for detecting the humidity and temperature of air in the room (own room) in which the dehumidifying dryer 70E is installed is disposed in the vicinity of the air inlet 15a. . The control unit (not shown in FIG. 9) selects the control content of at least one of the dehumidifying operation and the regeneration operation according to the detection result of the sensing unit 65.

  The configuration of the dehumidifying dryer 70E includes the sensing unit 65, and the point that the control unit selects the control content according to the detection result of the sensing unit 65 when performing at least one of the dehumidifying operation and the regeneration operation. 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 65 shown in FIG. 9 are denoted by the same reference numerals as those used in FIG.

  For example, when the humidity of the room where the dehumidifying dryer 70E is installed is high, the amount of moisture adsorbed per unit time by the adsorbent (not shown) carried by 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 70E is installed is low, the amount of moisture adsorbed per unit time by the adsorbent decreases. 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 65 is configured by a humidity sensor, the control unit detects that the humidity (relative humidity) equal to or higher than a predetermined value (hereinafter referred to as “second condition value”) is the sensing unit 65 ( When detected by the humidity sensor), 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 65 is less than the second condition value. Alternatively, the amount of power input to the heater 30 during the regeneration operation is increased.

  The second condition value is determined by the manufacturer of the dehumidifying dryer 70E and stored in advance in a storage element (not shown) in the control unit, for example. There may be only one second condition value, or two or more different values. Further, for each of the detection result of the sensing unit 65 being equal to or greater than the second condition value and less than the second 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 70E, and data for managing these by a method such as table management is stored in the storage element in advance. Is done.

When the dehumidifying dryer 70E is configured such that the control unit selects only one control content during the dehumidifying operation and the regeneration operation according to the detection result of the sensing unit 65, the other control content is the sensing unit 65. Regardless of the detection result, for example, the control content is preset by the manufacturer of the dehumidifying dryer 70E.

  When the dehumidifying operation and the regeneration operation are alternately performed under the control of the control unit, the sensing unit 65 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. ), The controller calculates the degree of the temperature rise, and the dehumidifying dryer 70E is configured to select the control content of at least one of the dehumidifying operation and the regenerating operation based on the result. be able to.

  That is, if the degree of temperature rise is less than a predetermined value (hereinafter referred to as “third condition value”), it is considered that the degree of drying and humidity of the indoor objects to be dried is low, and the degree of temperature rise. Is equal to or greater than the third condition value, it can be considered that the degree of drying and humidity of the indoor object to be dried is high. For example, in the same manner as when the sensing unit 65 is configured by a humidity sensor, the sensing unit 65 (temperature sensor) The dehumidifying dryer 70E can be configured so that the control unit selects the control content of at least one of the dehumidifying operation and the regeneration operation according to the detection result. The third condition value is determined by the manufacturer of the dehumidifying dryer 70E and is stored in advance in a storage element (not shown) in the control unit, for example. There may be only one third condition value, or two or more different values.

  When the sensing unit 65 is composed of a humidity sensor and a 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 70E can be configured to select the control content of at least one of the above. 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 65 is configured by only the humidity sensor.

  In the dehumidifying dryer 70E configured as described above, during the dehumidifying operation and the regeneration operation, depending on the air state of the room (own room) in which the dehumidifying dryer 70E 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 a sensing unit 65, and the control unit selects the control content of at least one of the dehumidifying operation and the regenerating 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 70E.
