I have.

  The determination value of the completion of drying is the total amount of drying until it can be determined that the clothes are dried. Hereinafter, in order to distinguish from the drying amount during the drying operation, it is referred to as the total drying amount.

  The storage means 34 is preferably, for example, a nonvolatile memory such as a flash memory built in the control unit 5 or an EEPROM, and can retain the stored contents even when the power is turned off.

  The drying speed calculation routine 31 calculates the drying speed of clothes based on the indoor temperature Tr detected by the temperature sensor 6 and the relative humidity Hr by the humidity sensor 7.

  In the above configuration, the operation of the dehumidifying device 1 of the present embodiment will be described below.

  The operation of the dehumidifier 1 is started by pressing the operation cut-off setting switch 13 connected to the operation display unit 8 after the user dries the clothes to be dried.

  When the user further operates the clothes drying setting switch 14 to select the clothes drying operation mode, the clothes drying operation is started.

  The operation of drying clothes is performed until the drying determination means 26 determines that the drying of clothes has been completed by the algorithm shown in the flowchart of FIG.

  First, when the operation of drying clothes is started, the clothes drying operation unit 15 sets the total drying amount and the drying amount of clothes as “0” as the determination value of the completion of drying by the initial setting means 21 as shown in FIG. Initialize to.

  The calculation value of the drying completion is calculated by the user by operating the clothing drying setting switch 14 with the total drying amount until the drying is completed corresponding to the temperature Tr and the relative humidity Hr detected by the temperature sensor 6 and the humidity sensor 7. The calculation is performed by referring to the drying completion dryness table 33 corresponding to the clothes drying operation mode.

  Next, if it is determined by the mode switching operation determination means 28 that there is no clothing drying operation mode setting switching operation, the drying amount correction routine 29 is not executed, and the operation control means 23 is operated by the dehumidifying driving means 16 and the air blowing driving means. 17 and the heater driving means 18 are controlled to drive the dehumidifying unit 2, the blower 3 and the regenerative heater 4.

It will be.

  Next, the drying speed calculation means 24 calculates the drying speed of the clothes based on the temperature Tr and the relative humidity Hr detected by the temperature sensor 6 and the humidity sensor 7 every predetermined period (for example, every minute), and calculates the drying amount. The means 25 calculates the amount of drying by adding the cumulative value of the drying rate for each fixed period.

  Here, the calculation of the drying speed of the clothing is performed by the drying speed calculation routine 31 based on the temperature Tr and the relative humidity Hr data. That is, the total heat quantity and absolute humidity of the ambient air are obtained from the temperature Tr of the ambient air and the relative humidity Hr. Further, the absolute humidity of the air near the clothing is estimated from the total amount of heat and the absolute humidity of the ambient air (in this case, the relative humidity of the air near the clothing is estimated as 100%). The drying speed is obtained by multiplying the difference between the absolute humidity of the air near the clothing estimated from the detection values of the temperature sensor 6 and the humidity sensor 7 and the absolute humidity of the ambient air calculated from the detection values of the temperature sensor 6 and the humidity sensor 7 by a coefficient. Is calculated.

In addition, the mode switching operation determination unit 28 of the operation mode switching correction unit 22 determines whether the operation mode switching unit 19 has performed an operation for switching the setting of the clothing drying operation mode of the clothing drying operation unit 15. When the setting switching operation is performed, the drying amount correction routine 29 corrects the drying amount of the clothes.

  In other words, the drying amount correction routine 29 refers to the drying completion dryness table 33 corresponding to the clothing drying operation mode selected by the user, refers to the total drying amount, and changes the clothing drying operation mode setting before switching. Unlike the initial setting means 21, the clothes drying operation is continuously executed without initializing “0” in order to continue the drying amount of the clothes to the operation in the clothes drying operation mode.

  Then, the completion of drying is determined by the drying determination means 26 arranged in the subsequent stage.

  The drying determination unit 26 determines whether the drying of clothes has been completed by determining whether or not the drying amount previously calculated by the drying amount calculation unit 25 has reached the total drying amount referred to from the drying completion drying degree table 33. It is.

  When the total dry amount has not been reached, it is determined that the drying has not been completed. Then, the clothes drying operation unit 15 returns to the operation mode switching correction unit 22 and repeats the clothes drying operation in the same manner.

  When the drying amount reaches the total drying amount, it is determined that the drying of the clothes is completed by the drying determination unit 26, and the dehumidifying drive unit 16, the blower driving unit 17, and the heater driving unit 18 are turned on by the stop unit 27. The output of the dehumidification part 2, the air blower 3, and the regeneration heater 4 is stopped by controlling.

  As described above, the dehumidifying device 1 of the present invention is operated by the operation mode switching correction means 22 even when the user changes the setting of the clothing drying operation mode by operating the clothing drying setting switch 14 during the clothing drying operation. By continuing to the clothes drying operation mode after switching without initializing the drying degree of the clothes before switching the mode, the drying amount calculating means 25 can continuously calculate the amount of drying of the clothes, and the drying The operation is stopped when the dry amount reaches the total dry amount corresponding to the clothes drying operation mode by the judging means 26.

  Accordingly, it is possible to reduce the excessive consumption of electric power and the excessive drying of clothes without performing useless clothes drying operation.

  The dehumidifying device of the present invention is a clothing drying operation mode after switching the amount of drying of the clothing before switching the clothing drying operation mode even when the setting of the clothing drying operation mode is switched during the clothing drying operation by the user. By continuing to run at the same time, it is possible to reduce excessive consumption of electricity and reduce excessive drying of clothes without performing wasteful clothes drying operation. It can be applied to other uses.
