  As shown in FIG. 2, the control unit 5 is configured with a microcomputer 21 as a core.

  The microcomputer 21 is connected to the dehumidifying device 2, the blower 3 and the regenerative heater 4 via the dehumidifying control means 22, the air blowing control means 23 and the heater control means 24, and the humidity sensor 7 and the clothes drying operation. A switch for operating the start, a setting switch for selecting and setting a clothing dryness, which will be described later, and an LED for displaying the clothing dryness are connected to the operation display unit 8.

  Here, the dehumidification control means 22 is, for example, a relay for switching a winding tap (not shown) of a motor for driving the regeneration fan 10, and the air blowing control means 23 is for driving the blower 3, for example. This is a relay for switching a winding tap (not shown) of the motor. The heater control means 24 is a relay for switching a tap (not shown) of the regenerative heater 4, for example.

  Further, as shown in FIG. 3, at the start of the clothes drying operation, the control unit 5 receives the signals from the temperature sensor 6 and the humidity sensor 7 and completes drying as a total drying amount from the temperature Tr of the surrounding air and the relative humidity Hr. An algorithm 5A for setting the determination value Dx of the garment, an algorithm 5B for calculating a drying rate Tt of the clothes based on the temperature Tr and the relative humidity Hr detected every certain period, and a drying rate Tt for this period every the certain period 5C for calculating the dry amount (Σ∫Tt) by adding the cumulative value ∫Tt of the sword, and an algorithm for determining that the drying of the garment has ended when the dry amount reaches the drying completion determination value Dx 5D, an algorithm 5E for correcting the drying completion determination value Dx according to the content of the setting change of the clothes dryness on the operation display unit 8, and the blower 3 according to the content of the dryness setting.

  In the microcomputer 21, the above-described main parts built in function based on the information of the temperature sensor 6, the humidity sensor 7, and the operation display unit 8, and the dehumidifying device 2, the blower 3, and the regenerative heater 4 It has the structure which controls.

  In the above configuration, the operation of the dehumidifier according to the present embodiment will be described below.

  The operation of drying the clothes by the dehumidifier according to the present embodiment is shown in the figure from when the user presses the start switch (not shown) of the clothes drying operation on the operation display unit 8 until the clothes drying operation is automatically terminated. The operation of the dehumidifier is advanced by the algorithm shown in the flowchart of FIG.

  In S11 of FIG. 3, the temperature sensor 6 and the humidity sensor 7 detect the temperature Tr and the relative humidity Hr of the air around the dehumidifier.

  Next, the algorithm 5A for setting the drying completion determination value Dx as the total drying amount corresponds to the temperature Tr and humidity Hr detected from the table 26 of the drying completion determination value Dx in S12. The drying completion determination value Dx is extracted and set.

  Next, in S13, the stored clothes dryness is read. The storage of the clothes dryness will be described later in S32.

  Next, in S14, the temperature Tr and humidity Hr of the air around the dehumidifier are detected for a certain time (for example, 1 minute).

  In S15, the algorithm 5B for calculating the clothes drying speed Tt is executed by the microcomputer 21 based on the temperature Tr and humidity Hr data in S15. That is, the total heat amount Ir and the absolute humidity Hr of the ambient air are obtained from the temperature Tr and the humidity Hr of the ambient air.

  Further, in S16, the drying condition calculation means 27 estimates the absolute humidity Xc of the clothing vicinity air from the total heat quantity Ir and the absolute humidity Xr of the ambient air (in this case, the relative humidity of the clothing vicinity air is estimated as 100%).

  In S <b> 17, the drying speed calculation unit 28 calculates the absolute humidity Xc of the air near the clothing estimated from the detection values of the temperature sensor 6 and the humidity sensor 7, and the absolute value of the ambient air calculated from the detection values of the temperature sensor 6 and the humidity sensor 7. A drying speed Tt (= α (Xc−Xr)) obtained by multiplying the difference from the humidity Xr by a coefficient α is calculated.

  This drying speed Tt is added and accumulated in the dryness calculating means 29 in S18 by the algorithm 5C for calculating the drying amount, and is stored in the memory in the microcomputer 21 as an added accumulated value ∫Tt.

  In S19, if the user does not change the setting of the clothes dryness on the operation display unit 8, the process jumps to S33 to be described later, but the user performs the operation of changing the setting of the clothes dryness on the operation display unit 8. When the clothing dryness setting content is level-2, the algorithm 5E corrects the drying completion determination value Dx according to the change in the clothing dryness setting. The drying completion determination value Dx is corrected to a value obtained by multiplying the completion determination value Dx by a coefficient a (for example, 0.6) and stored in the memory in the microcomputer 21. When the value is -1, the drying completion determination value Dx is corrected to a value obtained by multiplying the drying completion determination value Dx by a coefficient b (for example, 0.8) in S21 and stored in the memory in the microcomputer 21. When the dryness setting content is level +1, the drying completion determination value Dx is corrected to a value obtained by multiplying the drying completion determination value Dx by a coefficient c (for example, 1.2) in S22. It is stored in the memory in the computer 21, and when the dryness setting content is level +2, in S23, the drying completion value is multiplied by a coefficient d (for example, 1.6) to the drying completion determination value Dx. The determination value Dx is corrected and stored in the memory in the microcomputer 21.

  Next, by the algorithm 5F for changing the blowing power of the blower 3 according to the setting content of the clothes dryness, the blowing power of the blower 3 is lowered by two levels in S24 when the setting content of the clothes dryness is level-2. When the clothing dryness setting level is level-1, the blower power of the blower 3 is lowered by one level in S25, and when the clothing dryness setting content is level + 1, the blower power of the blower 3 is raised by one level in S26. When the clothes dryness setting content is level +2, the blower power of the blower 3 is increased by two levels in S27.

  Next, the algorithm 5G that switches the energizing power of the regenerative heater 4 according to the set content of the dryness causes the energizing power of the regenerative heater 4 to be 2 levels in S28 when the set content of the clothes dryness is level-2. When the setting value of the clothes dryness is level-1, the energizing power of the regenerative heater 4 is lowered by one level in S29, and when the setting content of the clothes dryness is level + 1, the energizing power of the regenerating heater 4 is decreased in S30 Is increased by one level, and when the set content of the clothes dryness is level +2, the energizing power of the regenerative heater 4 is increased by two levels in S31.

  Next, in S32, the setting value in which the clothes dryness is changed is stored in the operation display unit 8 in S19. Although not shown, a nonvolatile memory connected to the microcomputer 21 is used as a storage medium.

  Next, in S33, an LED corresponding to the set content of the clothes dryness is turned on so that the user can visually recognize the set content of the clothes dryness (the LED and specific display are not shown).

  In addition, the algorithm 5D that determines that the drying of the clothes has ended is performed in S34 by adding the cumulative value ∫Tt of the drying speed Tt in this period for each predetermined period, and the drying amount as the total drying amount. Completion of the drying determination value Dx is performed to check whether the drying is completed. If it is determined “NO” in this step, that is, if the drying amount is less than the total drying amount, the process returns to S14 again, and every minute. Tr and Hr are detected, and based on the detection, the above-described calculation operation is performed, and the driving is continued while calculating the cumulative value ∫Tt that is the dry state of the clothes. When the dry amount of the clothing reaches the total dry amount again in S34, the clothing drying operation is finished.

  As described above, the dehumidifier of the present invention corrects the drying completion determination value Dx according to the content change of the clothes drying degree, adjusts the automatic operation end condition, and sets the rotation speed of the blower and the regenerative heater. The dehumidifying ability of the dehumidifier is adjusted by adjusting the energizing power of the dehumidifier.

  By this, even if the environment for drying clothes changes due to the addition or taking-in of clothing, opening / closing of the door of the room, etc. during automatic driving, by adjusting the termination conditions and dehumidifying capacity of automatic driving, When automatic operation is finished, it is possible to prevent clothes from being dried out and to prevent excessive drying, and to perform efficient automatic drying of clothes.

  The dehumidifier of the present invention prevents the clothes from drying when the automatic operation ends even when the user changes the clothes drying environment by adding or taking in clothes or opening / closing the door of the room during the automatic operation. In addition, it can be applied to business use such as inns, regardless of household dehumidifiers, because it can prevent automatic drying of clothes and prevent excessive drying.
