(Embodiment 1)
FIG. 1 shows the main body of the dehumidifying device, FIG. 2 shows details of the operation unit, and FIG. 3 shows a control configuration diagram of the control unit 16.

  Although not shown, for example, a rotor filled with an adsorbent such as silica gel or zeolite that absorbs and releases moisture in the air is rotated by a motor, and the air to be dehumidified passes through the rotor filled with the adsorbent. The dehumidification material is dehumidification zone → regeneration unit with the rotation of the rotor by the motor by partitioning the dehumidification zone and the heating zone which is the regeneration unit through which the regeneration air heated by the heating means such as a heater passes. The heating zone → the dehumidification zone is repeatedly rotated in order.

  As a result, air to be dehumidified is blown from the blowing means such as a blower to the dehumidification zone, and is absorbed into zeolite, which is an example of an adsorbent, dehumidified and supplied as dry air. When the moisture absorption capacity of the zeolite is saturated due to moisture absorption, the rotation of the rotor causes the zeolite or other adsorbent absorbed in the dehumidification zone, that is, the hygroscopic material rotates and moves from the dehumidification zone to the heating zone that is the regenerative unit. The regenerated air heated by the heating means is blown to the heating zone which is the regenerating unit by the regenerative fan, so that the adsorbent absorbed in the dehumidification zone, that is, the moisture absorbed by the hygroscopic material is released and the dehumidified material is released. It will be regenerated and will regain its moisture absorption capacity.

  The high-temperature and high-humidity regenerated air released by the heating means and the regenerative fan is heat-exchanged with the air to be dehumidified by the heat exchange unit, cooled, condensed with water, and dehumidified from the regenerated air as water droplets. The regenerated air from which the moisture has been condensed and removed becomes dry air of low temperature and low humidity, and is circulated and supplied to the heating zone by the regenerative fan, and the moisture absorbed from the dehumidifying material is discharged to perform the dehumidifying material recycling process.

  The rotor rotates from the heating zone that is the regeneration unit to the dehumidification zone, and the above dehumidification is performed. Thereafter, the regeneration in the heating zone that is the regeneration unit is performed with the rotation of the rotor, and then the dehumidification in the dehumidification zone is performed. Repeated.

  The rotor, for example, as a desiccant rotor, carries a moisture absorbing / releasing material such as silica gel or zeolite in a cylindrical structure such as a honeycomb structure capable of ventilating in the axial direction of a rotating shaft rotated by a motor or a corrugated ceramic. Alternatively, it is possible to make a moisture absorbing / releasing material such as silica gel or zeolite into a honeycomb structure that can ventilate in the axial direction of the rotating shaft or a cylindrical structure such as a corrugated structure.

  As shown in FIGS. 1 to 3, a water storage tank 2 is disposed at the lower part of the dehumidifying device main body 1 to store the dew condensation water from the dehumidifying device main body 1.

It has been. A setting display unit 5 for displaying the setting by the switch is provided.

  The control contents of the control unit 16 are shown below. A pyroelectric human sensor 6 for detecting the presence of a person is disposed on the top surface of the main body, and the energization control status of the regenerative heater 7 as a heating means, that is, heating for representing the heating status is provided on the front surface of the main body. A display unit 8 is provided. The heating display unit 8 is composed of LEDs capable of lighting two colors of red and blue, and a weak heating display LED 8a that illuminates in red, which is a warm color when the regenerative heater 7 is weak, circulation. A color representing the heating status during operation, that is, a circulation LED 8d that lights in blue, which is a color other than red, is paired, and a medium heating display LED 8b that lights in red, which is a warm color when in the middle, turns blue during circulation operation A pair of circulation LEDs 8e to be lit, a strong heating display LED 8c to be lit red when the color is strong, and a pair of circulation LEDs 8f to be lit blue during the circulation operation are arranged.

  The operation unit 4 is provided with a heating display change switch 9 so that the user can change or turn off the brightness of the LED of the heating display unit 8. Further, inside the dehumidifying device main body 1, there are an operation display unit 3 and an operating unit 4, a blower fan 10 that sucks and discharges outside air from the main body, and a hygroscopic material 11 that is provided inside the hygroscopic device and adsorbs moisture in the passing air. In order to release moisture from the hygroscopic material 11, the regenerative heater 7 is a heating means for heating and regenerating the hygroscopic material 11. The regenerative heater 7 includes a regenerative heater 7a and a regenerative heater 7b. Further, a regeneration fan 12 that is a blowing means for circulating the regeneration air, a condenser 13 that condenses moisture released from the hygroscopic material 11, a temperature sensor 14 for detecting room temperature, and a room humidity. A humidity sensor 15 for detection is arranged, and a control unit 16 for controlling them is installed.

  In the above configuration, when the operation off / on switch 4a is pressed by the user, the control unit 16 receives the signal and drives each load according to the detection results from the temperature sensor 14 and the humidity sensor 15 to perform dehumidification. The device starts operation. The operation mode at this time is a preset dehumidifying operation or an operation used by the previous user. Further, at the start of operation, the control unit 16 displays the control content of the regenerative heater 7 using the heating display unit 8 in accordance with the content shown in Table 1. Table 1 shows an example in which the number of lighted LEDs increases or decreases in proportion to the power consumption of the heating means.

  The user can select another operation mode by pressing the dehumidification switching switch 4b and the clothing drying switch 4c. Since the user can select the operation mode according to his / her preference while confirming the control status of the regenerative heater 7 which is a heating means, an unintended increase in the room temperature can be prevented. At this time, when the user sets the human detection mode switch 4e, the control unit 16 drives the pyroelectric human sensor 6 as shown in Table 2.

  When the pyroelectric human sensor 6 detects the presence of a person, an increase in the room temperature can be suppressed by reducing the output of the regenerative heater 7 by one stage. Next, the operation during the protection operation will be described using Table 3.

  As shown in Table 3, the regenerative heater 7 is turned off when the room temperature is a low temperature of 0 ° C. or lower and a high temperature of 40 ° C. or higher to protect the equipment. At this time, the heating display unit 8 turns off the lighted LED among the weak heating display LED 8a, the middle heating display LED 8b, and the strong heating display LED 8c according to the output of the regenerative heater 7, and turns on the circulation LEDs 8d to 8f. By doing so, the user can recognize that it is equipment protection and call attention. In the entrusted operation for keeping the room humidity constant, if the room humidity is 55% or less, there is no need to dehumidify, so the controller 16 stops energization of the regenerative heater 7 and the room humidity is uneven. In order to reduce this, the operation is switched to the air blowing operation. At this time, the control unit 16 notifies the user that the circulation operation is being performed by displaying the heating display 8 in blue.

  Further, when the controller 16 energizes both the regeneration heaters 7a and 7b at the start of the dehumidifying operation, the regeneration heaters 7a and 7b are controlled by relays. If the relays that require a large amount of current for driving are driven simultaneously, the low voltage power supply of the control unit 16 will fluctuate. Therefore, a time lag that is a fixed time is provided for the relays of several + ms. At this time, when the heating display unit 8 is turned on at a timing according to the regenerative heater 7, a change in the display of the heating display unit 8 also causes a time lag, and the user feels uncomfortable. In order to prevent this phenomenon, the control unit 16 displays the heating status of the heating means on the heating display unit 8 after a predetermined time of about several + ms at a set stage.

  Next, when the amount of water stored in the water storage tank 2 that stores the condensed water from the dehumidifying device main body 1 is full due to the operation of the dehumidifying device, the control unit 16 stops the operation of the dehumidifying device main body 1 and displays heat. Is flashed as ON for 0.5 seconds and OFF for 0.5 seconds to prompt the user to drain the water storage tank 2. Moreover, when abnormality arises in the inside of the dehumidification apparatus main body 1, while the control part 16 stops the driving | operation of the dehumidification apparatus main body 1, it is ON for 0, 1 second, OFF for 0.1 second quicker than when it is full. By flashing in a proper manner, the user is informed that it is abnormal. For example, when the user uses the brightness of the heating display unit 8 at bedtime in a living space, the user can change the brightness or turn it off by pressing the heating display change switch 9 according to his / her preference.

  According to the first embodiment, the user can select the degree of increase in the room temperature according to the user's intention while grasping the increase in the room temperature. In addition, even when the user is away from the dehumidifying device, the state of the device can be confirmed at a glance by the display means, and a dehumidifying device with good visibility can be provided. it can.

  In addition, the user can arbitrarily select the luminance of the display means, and it is possible to provide a dehumidifying device that is easy to use and can reduce power consumption.
