  As a result, the user can arbitrarily select a timer setting value suitable for the usage environment, and the usability can be improved.

  FIG. 9 is a flowchart of the operation related to the silent control means 22.

  In process 46, if the setting contents of the silent control setting function 24 are valid, the process proceeds to process 47, and if invalid, the process proceeds to process 58.

  In process 47, it is determined whether or not the dehumidifying operation is performed by the power switch 10a. When the dehumidifying operation is being performed, the process proceeds to process 48, and when stopped, the process proceeds to process 54.

  In process 48, the value of the illuminance sensor 6 is read.

  In process 49, the read value of the illuminance sensor 6 read in process 48 is compared with the sensitivity setting value set by the sensitivity level setting function 26. The sensitivity setting value is determined by a sensitivity coefficient corresponding to the sensitivity level shown in FIG. For example, when the sensitivity setting value of the sensitivity level value 1 is 400, the sensitivity setting value of the sensitivity level value 2 is 400 × 0.8 = 320, and the brightness indicated by the sensitivity setting value increases as the sensitivity level increases. The surroundings of the main body 1 have bright illuminance. Here, the read value of the illuminance sensor indicates a brighter state as the value is darker and smaller. If the read value of the illuminance sensor 6 is greater than or equal to the sensitivity setting value, the process proceeds to process 50; otherwise, the process proceeds to process 53.

  In process 50, the timer operation time is counted as the time during operation control.

  In process 51, the silent control of the dehumidifier is performed. The silent control here is performed by lowering the rotational speed of the fan motor 20. Here, the rotation speed to be lowered is a method of lowering the original rotation speed at a constant rate (for example, the original rotation speed is reduced by 200 rotations of 800% / 25% per minute) or noise is sufficiently reduced. There is a method of uniformly lowering to a certain rotation speed (for example, 500 rotations). As a method for reducing the rotational speed of the fan motor, voltage control by a pulse width modulation method (PWM control) can be used.

  In process 52, the operation time after the start of operation control is counted. If the capacity of the memory for storing the count value of the process 52 is sufficiently large, it can also be used as the timer count value in the process 50.

  In the process 53, the timer count value after the silent control in the process 51 is started and the timer set value set by the timer setting function 28 are compared. When the timer count value is equal to or greater than the timer set value, the process proceeds to process 54, and when the timer count value is less than the timer set value, the process proceeds to process 50.

  In the process 54, the operation time count value after the silent control is started in the process 51 is compared with a predetermined time for masking to prevent chattering of the fan speed control in the silent control. Here, as an example of the mask predetermined time, 3 minutes is set for protection of the fan motor 20 and the regenerative heater. When the operation time count value is equal to or longer than the mask predetermined time, the process proceeds to process 55, and when the operation count value is less than the mask predetermined time, the process proceeds to process 51.

  In process 55, stop control of the dehumidifying operation is performed.

  In process 56, the timer count value is reset.

  In process 57, the count value of the operation time is reset.

  In process 58, the silent control is canceled and the normal operation control is resumed.

  As a result, noise can be reduced by lowering the rotation speed of the fan motor when the room illumination is dark, such as when the room illumination is turned off due to the brightness detection of the illuminance sensor 6, and the fan motor is linked with a timer. Noise prevention and energy-saving operation can be achieved by an arbitrary time after the rotation speed is lowered, that is, a function of stopping the operation after a predetermined time. The predetermined time may be arbitrarily selected according to the dehumidifying situation. For example, the dehumidifying operation is stopped after the dehumidifying operation for about 1 to 6 hours.

  Further, chattering can be prevented in the operation of controlling the rotational speed of the fan motor of the dehumidifier when the silent control is released.

  The operations described with reference to FIGS. 3 to 9 are implemented as control by a program operating in the microcomputer mounted on the control device 21.

For example, when the sensitivity setting value of the sensitivity level value 1 is 400, the sensitivity setting value of the sensitivity level value 3 is 400 × 0.4 = 160. The higher the sensitivity level, the closer the sensitivity setting value is to the vicinity of the main body 1 of the dehumidifier. Sensitive to the movements of people. Here, the reading value of the human sensor indicates that the greater the value, the less the reaction to the person and the smaller the value, the greater the reaction to the person. If the read value of the human sensor 60 is greater than or equal to the sensitivity setting value, the process proceeds to process 74, and otherwise, the process proceeds to process 78.

  In process 74, the timer operating time during silent control is reset.

  In process 75, the noise control of the dehumidifier is performed. The silent control here is performed by lowering the rotational speed of the fan motor 20. Here, the number of rotations to be lowered is a method of lowering the original number of rotations at a constant rate (for example, the original number of rotations is reduced by 200 rotations of 800% / 25% per minute) or noise is sufficiently reduced. There is a method of uniformly lowering to a certain rotation speed (for example, 500 rotations). As a method for reducing the rotational speed of the fan motor, voltage control by a pulse width modulation method (PWM control) can be used.

  In process 76, the brightness of each display on the display unit 11 is reduced. Here, as a method for reducing the brightness of the display unit 11, ON / OFF can be adjusted by repeating ON / OFF at intervals of about several tens of milliseconds and changing the ratio of the ON time to the OFF time.

  In process 77, the operation time after the start of operation control is counted. If the capacity of the memory for storing the count value of the process 77 is sufficiently large, the timer count value in the process 74 can also be used.

  In process 78, it is determined whether or not the silent control being processed in process 75 is in operation. If the silent control is in operation, the process proceeds to process 79, and if not, the process proceeds to process 81.

  In process 79, the timer time is counted as the time during silent control.

  In process 80, the timer count value after the silent control in process 75 is started is compared with the timer set value set by the timer setting function 28. When the timer count value is equal to or greater than the timer set value, the process proceeds to process 81, and when the timer count value is less than the timer set value, the process proceeds to process 75.

  In the process 81, the operation time count value after the silent control is started in the process 75 is compared with a predetermined time for masking to prevent chattering of the fan speed control in the silent control. Here, as an example of the mask predetermined time, 3 minutes is set for protection of the fan motor 20 and the regenerative heater. If the operation time count value is greater than or equal to the mask predetermined time, the process proceeds to process 82, and if the operation count value is less than the mask predetermined time, the process proceeds to process 75.

  In process 82, stop control of the dehumidifying operation is performed.

  In process 83, the brightness of each display on the display unit 11 is reduced. Here, as a method of realizing the process 83, the process 76 can be used.

  In process 84, the count value of the operation time is reset.

  In process 85, the timer operating time during the silent control is reset.

  In process 86, the silent control is canceled and the normal operation control is resumed.

  Thus, when a person is near the body 1 of the dehumidifier, noise can be reduced by lowering the number of revolutions of the fan motor, and further, a human sensor is provided by the function of stopping the operation after an arbitrary time after the person is gone. By detecting the presence / absence of a person by 60, noise can be prevented when a person is present, and an energy saving operation can be achieved by an automatic stop after a predetermined time, i.e., a predetermined time after the timer is not linked. The predetermined time may be arbitrarily selected according to the dehumidifying situation. For example, the dehumidifying operation is stopped after the dehumidifying operation for about 1 to 6 hours.

  Further, by reducing the display output while the silent control means 22 is operating, it is possible to prevent glare when the surroundings are dark and to save energy.

  Moreover, chattering can be prevented in the operation of controlling the rotational speed of the fan motor when the silent control is released.

  The operations described with reference to FIGS. 13 to 15 are implemented as control by a program operating in the microcomputer mounted on the control device 21.

FIG. 16 is a diagram showing a configuration of the operation display unit 5 according to the embodiment of the present invention.

  In FIG. 16, the difference between the first embodiment and FIG. 2 is that the operation unit 10 of the control device 21 has a silent level setting switch 10 g for selecting the degree of lowering the rotation speed of the fan motor in the silent control, and the display unit 11 has a silent sound. A silent level value 1 display unit 11m, a silent level value 2 display unit 11n, and a silent level value 3 display unit 11o for displaying level settings are provided.

  FIG. 17 is a diagram showing a configuration of the control device 21 and an input / output configuration according to the embodiment of the present invention.

  17 differs from FIG. 3 of the first embodiment in that a silent level setting function 90 is provided for determining the number of rotations the fan motor lowers with respect to the silent level set by the silent level switch 10g.

  FIG. 18 shows data not in the first embodiment among the data stored in the ROM in the microcomputer of the control device 21, and shows the relationship between the silent level set by the silent level setting switch 10g and the fan speed reduction rate. is there.

  FIG. 19 is a flowchart relating to the operation of the silent level setting function 90.

  In process 91, it is determined whether or not there is an input from the silent level setting switch 10g. If there is an input, the process proceeds to process 92, and if there is no input, the process of this flowchart is terminated.

  In process 92, it is determined whether the silent level being set is the maximum level value 3. If it is the maximum level, the process proceeds to process 93. Otherwise, the process proceeds to process 94. In process 93, the silent level is set to the minimum level 1. In process 94, the silent level is set to a level that is one level higher than the level being set (+1).

  As a result, the user can arbitrarily select a value for decreasing the number of rotations of the fan motor suitable for the usage environment, thereby improving usability.

  FIG. 20 is a flowchart regarding the operation of the silent control operation display function 25.

  In FIG. 20, differences from the first embodiment will be described. In the process 95, when the rotational speed of the fan motor is lowered, the rotational speed of the fan motor is lowered according to the silent level set by the silent level setting function 90. For example, if the fan motor rotation speed before starting the silent control is 900 rotations and the silent level is the silent level value 2, it is lowered by 270 rotations at 900 × 0.3 (output is 900-270 rotations at 630 rotations). .

  As a result, while the user selects the balance between the dehumidifying capacity and the noise reduction, when the human sensor 60 detects the presence or absence of a person, the number of rotations of the fan motor is reduced when there is a person near the body 1 of the dehumidifying device. In addition, the function to stop operation after a predetermined time after the time when the person is gone by interlocking with a timer can be used to prevent noise when there is a person and to save energy by automatic stop after the person is gone. Can do. The predetermined time may be arbitrarily selected according to the dehumidification situation, and is, for example, about 1 to 6 hours.

  Further, by reducing the display output while the silent control means 22 is operating, it is possible to prevent glare when the surroundings are dark and to save energy.

  Further, chattering can be prevented in the operation of controlling the rotational speed of the fan motor when the silent control is released.

  The operations described above with reference to FIGS. 18 to 20 are implemented as control by a program operating in the microcomputer mounted on the control device 21.

  Note that the above-described method according to the third embodiment performs the same addition in FIG. 16 and FIG. 17 in the second embodiment, similarly using FIG. 18 and FIG. 19, and processing 95 in FIG. The processing 75 can be easily realized by replacing in the same manner.

  The technology for controlling the rotation speed of the fan motor by the detection result of the illuminance sensor or the human sensor of the present invention and timer control reduces the noise when the surroundings of the device body is dark, such as when the indoor lighting is turned off, and can be arbitrarily The effect of energy-saving operation by stopping the operation after time, the effect of energy-saving operation by reducing the noise when there is a person and stopping the operation after an arbitrary time after there is no one, It can also be applied to household appliances such as purifiers and humidifiers, commercial equipment, and industrial equipment.
