The regenerative heater here is configured such that the power consumption of the regenerative heater H16 is greater than that of the regenerative heater L15, but each role is the same, so that the dehumidifying ability can be adjusted in stages. This is the configuration. Further, the control device 13 includes a load drive circuit 19 composed of electronic parts such as a triac and a relay for driving a load, and a microcomputer 20 having a RAM, a ROM such as a counter, a timer and a clock function inside. Yes. Here, the operation of the microcomputer 20 is carried out in the form of a microcomputer program in cooperation with a counter, timer, clock function, RAM, and ROM in the microcomputer.

  In the dehumidifying apparatus configured as described above, a method of drying the clothes by the dehumidifying apparatus when the size of the room and the weight of the clothes are set will be described with reference to FIGS.

  As shown in FIG. 3, when the power is turned on in Step 1 and the clothes drying operation of the dehumidifying device is started in Step 2, the process proceeds to Step 3 to set the dryness Dx1 as the initial value of the dryness Dx.

  The degree of dryness Dx is a value by which the value of the parameter D shown in FIG. 4 determined by the temperature and humidity values is subtracted at regular time intervals, and it is determined that the clothes are dry when the value becomes a certain value or less. It is. The dryness Dx1 as an initial value is a value empirically determined from the dehumidification capability of the dehumidifier, the size of the room, and the dryness of the clothing based on the weight of the clothing. Here, the room size is 6 tatami mats. And it is a fixed value memorize | stored in the microcomputer 20 beforehand as a value when clothing weight is 6 kg. In addition, the parameter D is empirically determined by verifying the temperature and humidity of the room and the drying condition of the object to be dried, such as clothes, when the object to be dried such as clothes is dried. The value to be determined. Furthermore, the dryness Dx1 as the initial value of the dryness Dx is a value that is much larger than the parameter D shown in FIG. Next, the process proceeds to step 4 where the room size set by the room size setting means 9 is confirmed. Here, if the room size is set, the process proceeds to step 5 to determine the room size coefficient F shown in FIG.

  The coefficient F is a value determined empirically from the verification of the dryness of clothes by the dehumidifying capacity of the dehumidifying device and the size of the room. Here, 1 is set when the room size is 6 tatami, 1 is set when the room size is larger than 6 tatami, and 1 is set when the room size is smaller than 6 tatami. A negative value smaller than is set. Accordingly, it is possible to adjust the operating time of the dehumidifier according to the size of the room by increasing or decreasing the dryness Dx1 as the initial value of the dryness Dx in consideration of the size of the room.

  If the room size setting means 9 is not set in step 4, the process proceeds to step 15 and 0.0 is set to the room size coefficient F. Next, the process proceeds to step 6 where the clothing weight set by the clothing weight setting means 11 is confirmed. If the clothing weight is set, the process proceeds to step 7 to determine the clothing weight coefficient G shown in FIG.

  The coefficient G is a value determined empirically from the verification of the dryness of the clothing by the dehumidifying ability of the dehumidifying device and the clothing weight. Here, 1 is set when the clothing weight is 6 kg, a positive value smaller than 1 is set when the clothing weight is larger than 6 kg, and a negative value smaller than 1 is set when the clothing weight is smaller than 6 kg. ing. Accordingly, it is possible to adjust the operating time of the dehumidifier according to the clothing weight by increasing or decreasing the drying degree Dx1 as an initial value of the drying degree Dx in consideration of the clothing weight.

  If the clothing weight setting means 11 is not set in step 6, the process proceeds to step 16 to set 0.0 to the clothing weight coefficient G. Next, the process proceeds to step 8 where the dryness Dx1 is multiplied by the coefficient F of the room size and the coefficient G of the clothing weight to calculate the dryness Dx2 in consideration of the influence of the room size and the clothing weight. Then, after a predetermined time T has elapsed in step 9, the process proceeds to step 10, and the humidity H and temperature R of the room are detected from the temperature / humidity sensor 8. Next, the process proceeds to step 11 where the parameter D shown in FIG. 4 is selected from the humidity H and the temperature R of the room.

  In step 12, the parameter D is subtracted from the dryness Dx2 to calculate the dryness Dx. In step 13, the dryness Dx2 is updated to the value of the dryness Dx. Next, in step 14, it is confirmed whether or not the value of the dryness Dx is less than or equal to zero. If the dryness Dx is not less than or equal to zero, it is estimated that an object to be dried such as clothes is not dry, and the process proceeds to step 9. . If the dryness Dx is not zero in step 14, step 9 to step 14 are repeated. Then, when the dryness Dx becomes zero or less in Step 14, the process proceeds to Step 17, where it is estimated that the object to be dried such as clothes is dried, and the operation of the dehumidifier is stopped. By performing such an operation, it becomes possible to set the size of the room and the weight of the object to be dried such as clothes, and it is possible to accurately estimate the dryness of the object to be dried such as clothes and stop automatically. A dehumidifying device is obtained.

  Here, a coefficient is applied to the degree of dryness Dx1 to reflect the influence of the size of the room and the weight of clothing. However, if the original data is optimally changed according to the size of the room and the weight of clothing, the method is limited to that method. No difference is made in the effect.

  Although not shown in the figure, the room size may be displayed as an area. If the room type is displayed together with the area of the room, the size of the room can be easily understood. it can.

  Although not shown in the figure, if the room size is displayed as a volume, the accuracy of the room size can be improved.

  Although not shown in the figure, if LEDs are used to display the size of the room and the weight of clothes, the display can be realized by an inexpensive method.

  Although not shown in the figure, if a liquid crystal is used to display the size of the room and the weight of clothing, it is possible to realize an easy-to-understand display using characters and pictures.
