It is what.

  For example, the storage means is preferably a nonvolatile memory represented by 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 36 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 28 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.

  Calculation of the determination value for completion of drying is performed according to the following procedure. First, the drying speed is obtained from the temperature Tr and the relative humidity Hr detected by the temperature sensor 6 and the humidity sensor 7 at the start of clothes drying operation. The integrated value of the drying speed corresponds to the total drying amount. Actually, it is calculated by referring to the drying completion dryness table corresponding to the clothing drying operation mode selected by the user by operating the clothing drying setting switch 14. Done. Then, based on the dry completion dryness obtained from the dry completion dryness table, the completion of drying is determined.

  Next, the dehumidifying operation means 22 acquires output control patterns of the dehumidifying driving means 16, the air blowing driving means 17, and the heater driving means 18 from the output control pattern table corresponding to the dehumidifying ability in the selected clothes drying operation mode, and will be described later. Drive control is performed by the operation control means 25. In the output control pattern table, combinations of output notches of the dehumidifying driving means 16, the air blowing driving means 17, and the heater driving means 18 are stored in the storage means.

  If the mode switching operation determination unit 30 determines that there is no clothing drying operation mode setting switching operation, the drying amount correction routine 31 and the dehumidifying capability correction unit 24 are not executed.

  Next, the operation control means 25 controls the dehumidification drive means 16, the air blow drive means 17 and the heater drive means 18 based on the output control pattern table acquired by the dehumidification operation means 22. And the dehumidification part 2, the air blower 3, and the reproduction | regeneration heater 4 are driven, and the air dehumidified by the clothing to be dried is ventilated.

  Next, the drying rate calculating means 26 calculates the drying rate of the clothes based on the temperature Tr and the relative humidity Hr detected by the temperature sensor 6 and the humidity sensor 7 at regular intervals (for example, every minute). Then, the dry amount is calculated by adding the cumulative value of the drying speed for each fixed period by the dry amount calculating means 27.

  Here, the calculation of the clothing drying speed is performed by the drying speed calculation routine 36 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%). Then, the drying speed is calculated by multiplying the difference between the absolute humidity of the air near the clothing and the absolute humidity of the ambient air by a coefficient.

  Now, the user may switch the setting of the clothes drying operation mode with different dehumidifying capabilities by operating the clothes drying setting switch 14 while confirming the drying condition of the clothes during the clothes drying operation. For this purpose, as shown in FIG. 4, the mode switching operation determination unit 30 of the operation mode switching correction unit 23 determines whether the setting switching operation of the clothing drying operation mode has been performed. When there is an operation for switching the setting of the clothes drying operation mode, the drying amount of the clothes is corrected by the drying amount correction routine 31.

  That is, the dry amount correction routine 31 refers to the total dry amount with reference to the dry completion dryness table corresponding to the clothes drying operation mode selected by the user. In order to continue the operation of the clothing drying operation mode after switching the clothing drying operation mode before switching the clothing drying operation mode, the clothing drying operation is not performed without initializing “0” unlike the initial setting means 21. Continue to operate.

  Then, the completion of drying is determined by the drying determination means 28 arranged in the subsequent stage. The drying determination means 28 determines whether the drying of clothes has been completed by determining whether or not the drying amount previously calculated by the drying amount calculation means 27 has reached the total drying amount referred to from the drying completion drying degree table. is there.

  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 means 23 and repeats the clothes drying operation in the same manner.

  On the other hand, when the drying amount reaches the total drying amount, the drying determination unit 28 determines that the drying of the clothing has been completed, and the stop unit 29 causes the dehumidification driving unit 16, the blower driving unit 17, and the heater driving unit 18 to be changed. The output of the dehumidification part 2, the air blower 3, and the regeneration heater 4 is stopped by controlling.

  Furthermore, when the dehumidifying ability switching change determining means 32 of the dehumidifying ability correcting means 24 switches the setting in the direction of increasing the dehumidifying ability in the clothes drying operation mode (UP), the user operates in a shorter time until the clothes drying is completed. Judge that you want to. Then, the dehumidifying capacity UP correction routine 33 determines the output notch of the dehumidifying driving means 16, the blower driving means 17 and the heater driving means 18 acquired from the output control pattern table corresponding to the dehumidifying capacity in the clothing drying operation mode selected by the user. Compensates for output notches with higher levels.

Further, when the dehumidifying ability switching change judging means 32 switches the setting to the direction in which the dehumidifying ability in the clothing drying operation mode is lowered (DOWN), the user judges that the user desires to dry the clothes with low noise and low power consumption. . And the level of the output notch of the dehumidifying drive means 16, the blower driving means 17 and the heater driving means 18 acquired from the output control pattern table corresponding to the dehumidifying capacity in the clothing drying operation mode selected by the user in the dehumidifying capacity DOWN correction routine 34. The output is corrected to a lower output notch.

  The dehumidifying capacity of the dehumidifying capacity correcting means 24 is corrected by correcting the output notches of the three driving means of the dehumidifying driving means 16, the air blowing driving means 17 and the heater driving means 18, but either one or two It is also possible to correct the output notch of the driving means.

  As described above, the dehumidifying device 1 of the present invention is operated by the operation mode switching correction means 23 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. The garment drying operation mode after switching is continued without initializing the dryness of the garment before switching the mode. Thus, the dry amount calculation means 27 can continuously calculate the dry amount of the clothes. Then, when the drying amount reaches the total drying amount corresponding to the clothes drying operation mode, the operation is stopped.

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

  Further, when the user changes the setting of the clothes drying operation mode by operating the clothes drying setting switch 14 during the clothes drying operation, the dehumidification is performed in accordance with the change in the dehumidifying capacity of the clothes drying operation selected by the dehumidifying capacity correcting means 24. The ability is corrected.

  As a result, the clothes drying operation according to the intention of the user to dry the clothes can be performed, and the usability can be improved.

  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 and correcting the dehumidifying capacity according to the change in the dehumidifying capacity of the selected clothing drying, it is possible to reduce excessive consumption of electricity and excessive drying of clothing without performing wasteful clothing drying operation. Since the clothes can be dried according to the user's intention to dry clothes, the application can be applied to business use such as inns regardless of the dehumidifying device for home use.
