The rear frame 12 has a suction port 21 , a tank insertion port 22 , a water filling port 23 and a lever support port 24 . The suction port 21 has a plurality of slits 26 and has a filter 27 and a filter case 28 on its outer surface. The filter 27 is made of resin mesh, non-woven fabric, or the like, and removes dust, odor components, and the like from the intake air. Filter case 28 fixes filter 27 to suction port 21 . The tank insertion port 22 is arranged below the suction port 21, through which the drain tank 51 is inserted and taken out. The water injection port 23 and the lever support port 24 are arranged above the suction port 21 . The rear frame decorative plate 13 is attached above the rear frame 12 to cover a portion of the rear frame 12 that is not desired to be visually recognized.

The top plate 14 is arranged above the combined front frame 11 and rear frame 12 to form the housing 10 facing upward. The upper plate 14 has an air outlet 31 , an operation section 32 and an LED display section 33 . The air outlet 31 is arranged on the surface of the top plate 14 facing upward. The air outlet 31 has a louver unit 35 capable of controlling the blowing direction of dry air. The louver unit 35 has a louver 36 composed of a main louver 36 a and an auxiliary louver 36 b and a louver motor 37 that drives the louver 36 .

The operation unit 32 and the LED display unit 33 are arranged on a surface that inclines downward and forward from the upper surface. The operation unit 32 has a plurality of operation switches 32a such as an operation switch, a timer switch, and an operation mode selection switch displayed on a panel. The electrostatic capacitance value detected by changes, and the presence or absence of operation of the operation switch 32a can be determined based on whether the electrostatic capacitance value reaches a predetermined value or more. The LED display unit 33 displays the operating state and the like set by operating the operation switch 32a in a lighting state of an LED (Light Emitting Diode).

The base 15 is arranged below the combined front frame 11 and rear frame 12 and serves as the base of the dehumidifier 1 .

The main internal parts of the dehumidifier 1 accommodated in the housing 10 include a fan case 41, a sirocco fan 42, a blower motor 43, a heater 44, a compressor 45, a heat exchanger 46, and a drain pan. 49 , a drain tank 51 and a controller 55 .

The fan case 41 is arranged on the base 15 and mainly supports and positions a sirocco fan 42 as a blower fan, a blower motor 43 and a drain tank 51 .

A sirocco fan 42 as a blower fan is rotated by the rotation of the blower motor 43 , draws in air from the suction port 21 , and forms an air flow that blows out from the blowout port 31 . The sirocco fan 42 and the blower motor 43 are attached to the fan case 41 so that their rotating shafts extend in the front-rear direction. The blower motor 43 can be set to a plurality of stages of rotation speed, and is set to a predetermined rotation speed according to the operation mode and the indoor temperature and humidity, and rotates the sirocco fan 42 .

The heater 44 is installed in the airflow passage between the heat exchanger 46 and the blowout port 31, and when energized, the heater is driven and raises the temperature of the air passing through the airflow passage. In particular, when the heater 44 is driven during the clothes drying operation for drying the washed clothes above the air outlet 31 of the dehumidifier 1, high-temperature warm air is blown out from the air outlet 31 to quickly dry the clothes. Since the clothes can be dried, the efficiency of the clothes drying operation can be improved.

The compressor 45 is fixed on the base 15 and connected to the heat exchanger 46 via a refrigerant pipe 45a and a pressure reducing device 45b.

The heat exchanger 46 exchanges heat with the air sucked from the suction port 21 . The heat exchanger 46 has an evaporator 46a as dehumidifying means arranged near the suction port 21, and a condenser 46b arranged in front of the evaporator 46a. The evaporator 46 a and the condenser 46 b are fin-tube heat exchangers in which fins 48 are attached to U-shaped refrigerant pipes 47 . As shown in FIG. 2, the refrigerant pipe 47 has a plurality of straight portions 47a extending in the horizontal direction (lateral direction) and a bent portion 47b that bends in the vertical direction and connects the two straight portions 47a. The portion 47 a and the bent portion 47 b appear continuously along the length of the refrigerant pipe 47 .

Compressor 45, refrigerant pipe 45a, decompression device 45b, and heat exchanger 46 form a refrigeration cycle through which refrigerant flows. The refrigerating cycle is composed of a compressor 45, a condenser 46b, a decompression device 45b, and an evaporator 46a in order of refrigerant flow, which are connected by a refrigerant pipe 45a. When the refrigerant flows through the evaporator 46a, the refrigerant takes heat from the air passing through the evaporator 46a and evaporates. Also, as the refrigerant flows through the condenser 46b, it reheats and condenses the air passing through the condenser 46b. As a result, the air sucked from the suction port 21 is filtered by the filter 27 to remove dust, odor components, etc., cooled and dehumidified by the evaporator 46a, and then heated by the condenser 46b to form low-humidity air. It is discharged from the outlet 31 .

The drain pan 49 supports and fixes the heat exchanger 46 from below on the opposite side of the fan case 41 in the front-rear direction to the side on which the sirocco fan 42 is arranged. The drain pan 49 engages with the refrigerant pipes 47 and the fins 48 located below the heat exchanger 46 to support the heat exchanger 46 in the front-rear and left-right directions. The drain pan 49 has a drain port, receives drain water generated and dropped from the evaporator 46a and washing water used to wash the evaporator 46a, and discharges the drain water from the drain port.

The drain tank 51 stores drain water discharged from the drain port of the drain pan 49 . The drain tank 51 is attached to and detached from the housing 10 by being slid in the front-rear direction from the tank insertion opening 22 . The drain tank 51 inserted into the housing 10 is arranged in the tank chamber 41 b formed by the fan case 41 .

The drain tank 51 has a tank lid 54 and a floating accommodation portion 52 . The tank lid 54 drops drain water and the like from the drain port of the drain pan 49 into the drain tank 51 . The float housing portion 52 houses a float 53 having, for example, a magnet for detecting the water level in the drain tank 51 . The magnetic field of the magnet corresponding to the water level is detected by an AMR sensor (Anisotropic-Magneto-Resistance, anisotropic magnetoresistance sensor) 62 mounted on the control unit 55 or the like, and notifies the user that the drain tank 51 is full.

The control unit 55 is supported by the case 56 and arranged on the left side of the fan case 41 . The control unit 55 electrically controls each unit such as the louver motor 37, the blower motor 43, the heater 44, the compressor 45, and the LED display unit 33 based on instructions from the operation unit 32 and prestored programs. , controls the operation of the dehumidifier 1 in an integrated manner. As shown in FIG. 6, the control section 55 has a storage section 57 and a timer 58 . The storage unit 57 stores an operation program of each unit and the like. The timer 58 measures time for timer operation of the dehumidifier 1 and the like. The calculation unit 63 calculates a predetermined operation time, which is the execution time of the clothes drying operation, using a predetermined formula based on the temperature detected by the temperature sensor 59 and the humidity detected by the humidity sensor 60 .

The controller 55 has a temperature sensor 59 and a humidity sensor 60 . A temperature sensor 59 and a humidity sensor 60 are provided at predetermined positions on the main body of the dehumidifier 1 to detect the ambient temperature and humidity of the dehumidifier 1 . The control unit 55 uses temperature and humidity as necessary to control each unit. The notification unit 61 outputs an alarm sound for informing the user of the situation based on an instruction from the control unit 55 . The control unit 55 also has a heat exchanger temperature sensor 64 . A heat exchanger temperature sensor 64 is provided at a predetermined position of the condenser 46b and measures the temperature of the condenser 46b.

Next, the clothes drying operation in the dehumidifier 1 will be described.

The user hangs the wet clothes after washing on the outlet 31 of the dehumidifier 1 before executing the clothes drying operation. When the control unit 55 determines that the user's finger has approached or touched the operation switch 32a for starting the clothes drying operation on the operation unit 32 and has issued an instruction to start the clothes drying operation, the louver motor 37, the air blower motor 43, and the compression unit 55 The machine 45 and the heater 44 are driven to start the clothes drying operation. Specifically, the control unit 55 drives the louver motor 37 so as to swing the main louver 36a and the auxiliary louver 36b in a predetermined manner, thereby blowing air to the entire clothes hung on the air outlet 31. . The control unit 55 drives the blower motor 43 so that the sirocco fan 42 operates at a preset rotation speed.

When the clothes drying operation is started, the air sucked into the housing 10 by the sirocco fan 42 is dehumidified by the evaporator 46a, and the dehumidified air is heated by the heater 44 and blown out from the outlet 31 to dry the clothes. Wet clothes can be dried efficiently by blowing air into the air.

The controller 55 counts the elapsed time from the start of the clothes drying operation with the timer 58 , and stores the values detected by the temperature sensor 59 and the humidity sensor 60 at predetermined time intervals in the storage unit 57 . The control unit 55 uses the calculation unit 63 to calculate a predetermined operation time, which is the operation time of the clothes drying operation, based on the detection values of the temperature sensor 59 and the humidity sensor 60 stored in the storage unit 57 and a predetermined calculation formula. . When the control unit 55 determines that the elapsed time of the clothes drying operation counted by the timer 58 has reached the predetermined operation time calculated by the calculation unit 63, the control unit 55 stops the blower motor 43, the compressor 45, and the heater 44. , the louver motor 37 is operated so that the louver 36 moves to the position where the air outlet 31 is closed, and the clothes drying operation is completed.

By performing the clothes drying operation for a predetermined operation time in this manner, the air dehumidified by the evaporator 46a and heated by the heater 44 is blown to the clothes hung on the air outlet 31, so that the clothes are dried. Efficient drying.

Next, the contents of control when the plurality of operation switches 32a of the operation unit 32 are pressed simultaneously due to the falling of the dried clothes during the clothes drying operation will be described with reference to the flow chart of FIG.

After starting the clothes drying operation, the control unit 55 determines whether the state in which the capacitance values of the plurality of operation switches 32a have exceeded a predetermined value has continued for several seconds (step S101). When it was determined that the state of the capacitance value exceeding the predetermined value continued for several seconds, the clothes dried on the housing 10 fell and the top surface of the housing 10 including the operation unit 32 was covered with the clothes. In this state, the heater 44 is stopped, the sirocco fan 42 is set to the maximum air volume, which is a predetermined large air volume, and the louver motor 37 is rotated so that the louver 36 is parallel to the vertical direction, which is a predetermined large air volume angle. The clothes dropping operation to be driven is started (step S102). When the clothes dropping operation is started, the timer 58 starts counting the elapsed time of the clothes dropping operation, and continuously confirms the capacitance values of the plurality of operation switches 32a at predetermined time intervals to monitor changes. When the control unit 55 determines that the state in which the capacitance values of the plurality of operation switches 32a are equal to or greater than the predetermined value has not continued for several seconds (No in step S101), the control unit 55 performs processing to continue the clothes drying operation. (Step S103), the determination of step S101 is repeated again.

When the control unit 55 determines that the process of step S102 is completed, the control unit 55 determines whether the temperature detected by the heat exchanger temperature sensor 64 is equal to or higher than a predetermined high temperature value of 70° C. (step S104). C. or higher, the compressor 45 is stopped while the sirocco fan 42 continues to operate, thereby preventing product failure due to abnormally high temperature refrigerant flowing through the refrigeration cycle (step S105). If it is determined that the temperature detected by the heat exchanger temperature sensor 64 is less than 70° C. (No in step S104), it will be described later.

When the process of step S105 is completed, the control unit 55 determines whether the temperature detected by the heat exchanger temperature sensor 64 is 40° C. or lower (step S106). Assuming that the flowing refrigerant is sufficiently cooled and there is no risk of product failure, the compressor 45 is driven again (step S107). If the controller 55 determines in step S106 that the temperature detected by the heat exchanger temperature sensor 64 exceeds 40° C., it repeats the determination in step S106.

When the controller 55 makes a No determination in step S104 or completes the process of step S107, the control unit 55 determines whether the elapsed time counted by the timer 58 from the start of the clothes dropping operation is greater than or equal to a predetermined time, which will be described later ( Step S108), when it is determined that the elapsed time is equal to or longer than the predetermined time, the heater 44, the blower motor 43, and the compressor 45 are stopped, and the louver motor 37 is driven so that the louver 36 is positioned at the position where the outlet 31 is closed. , the operation of the clothes dropping operation is stopped (step S109). If the controller 55 determines that the elapsed time is less than the predetermined time in step S106 (No in step S108), it repeats the determination in step S104.

Next, the predetermined time in step S108 will be described.

When the clothes dropping operation is started, the heater 44 is stopped, so the temperature of the blown air is lower than in the normal clothes drying operation, and the clothes drying efficiency is lowered. Further, when most of the suction port 21 and/or the air outlet 31 are covered with the fallen clothes, the temperature inside the housing 10 rises and the compressor 45 is stopped in step S202. can not be used, and the efficiency of drying clothes decreases. Therefore, by setting the operation time when the clothes dropping operation is performed to be longer than the predetermined operation time of the normal clothes drying operation, the clothes are dropped from the housing 10 and dried on the housing 10. Drying of clothes can be accelerated.

At the time of the determination in step S108, the control unit 55 calculates the operating time when the normal clothes drying operation is continued from the indoor temperature, the indoor humidity, the operating time, etc. before the clothes dropping operation is started, by the calculating unit 63, A time longer than the calculated operating time is set as the predetermined time. Thus, when the clothes dropping operation is started, air is blown for a longer time than when the normal clothes drying operation is continued, so that drying of the clothes hung on the housing 10 can be accelerated.

In the present embodiment, a predetermined large air volume of the sirocco fan 42 in the clothes dropping operation of step S102 is set as the maximum air volume, but the present invention is not limited to this. For example, if the air volume during the normal clothes drying operation is a predetermined value that is less than the maximum air volume, by setting an air volume value larger than that during the normal clothes drying operation as the predetermined large air volume during the clothes dropping operation, the normal Since a larger amount of air is blown from the air outlet 31 than during the clothes drying operation, the clothes that have fallen so as to cover the top of the housing 10 can be more likely to be dropped from the housing 10 by the clothes dropping operation. .

Further, in the present embodiment, the louver 36 is fixed at a position parallel to the vertical direction, which is a predetermined large air volume angle, in the clothes dropping operation in step S102, but the present invention is not limited to this. For example, after fixing the louver 36 at a position parallel to the vertical direction, the louver motor 37 may swing the main louver 36a and the auxiliary louver 36b at predetermined time intervals. Swinging the louver 36 can increase the possibility that clothes caught on the outlet 31 will fall from the housing 10 .

Further, in the present embodiment, whether or not the clothes dropping operation is stopped is determined based on whether or not the uniform elapsed time has reached a predetermined time or longer regardless of whether or not the compressor 45 is stopped in step S105, but the present invention is not limited to this. When the compressor 45 is stopped in step S105 because the heat exchanger temperature during the clothes dropping operation exceeds a predetermined high temperature value, the room air cannot be dehumidified by the evaporator 46a for a period of time, and the clothes drying efficiency decreases. do. The control unit 55 adds the stopping time of the compressor 45 to the predetermined time of step S108 so that the duration of the clothes dropping operation is lengthened according to the time when step S105 occurs. As a result, the air blowing time onto the housing 10 is lengthened, so that the drying of the clothes hung on the housing 10 can be accelerated.

Next, effects of the present invention will be described.

When the control unit 55 determines that the capacitance values of the plurality of operation switches 32a simultaneously exceed a predetermined value during the clothes drying operation, the controller 55 stops the heater 44 and operates the sirocco fan 42 at the maximum air flow rate, which is a predetermined large air flow rate. drive. During the clothes drying operation, when the wet clothes dried on the housing 10 fall and the plurality of operation switches 32a are pressed simultaneously, the heater 44 is stopped so that the clothes come into contact with the heater 44. to prevent dangerous situations from occurring. In addition, by blowing the maximum amount of air from the air outlet 31, the clothes covering the housing 10 are dropped, and the possibility of continuing the drying of the clothes hung on the housing 10 is increased, and the drying of the clothes is increased. It is possible to prevent shortages from occurring.

Further, when the controller 55 determines that the capacitance values of the plurality of operation switches 32a simultaneously exceed a predetermined value during the clothes drying operation, the louver 36 is positioned parallel to the vertical direction at a predetermined large air volume angle. The louver motor 37 is driven. During the clothes drying operation, when the wet clothes dried on the housing 10 fall and the plurality of operation switches 32a are pressed simultaneously, the air outlet 31 is opened by placing the louver 36 in a position parallel to the vertical direction. Since the clothes receive the maximum amount of air blown from the housing 10 and the possibility of the clothes falling from the housing 10 is increased, the possibility of continuing to dry the clothes hung on the housing 10 is increased. Insufficient drying can be prevented.

In addition, the control unit 55 determines that the capacitance values of the plurality of operation switches 32a simultaneously exceed a predetermined value during the clothes drying operation, stops the heater 44, and rotates the sirocco fan 42 to a predetermined maximum air volume. When it is determined that the detected value of the heat exchanger temperature sensor 64 has reached a predetermined high temperature value of 70° C. or higher after driving with the air volume, the compressor 45 is stopped and the sirocco fan 42 is continued to be driven. During the clothes dropping operation, most of the suction port 21 and/or the air outlet 31 are covered with the clothes, the heat dissipation efficiency of the heat exchanger 46 is lowered, and the inside of the housing 10 becomes hot. When the value detected by the heat exchanger temperature sensor 64 becomes a predetermined high temperature value or higher, the risk of product failure due to the high temperature of the refrigerant increases, so the compressor 45 is stopped and the sirocco fan 42 is continued to be driven to continue the refrigeration. Cools the refrigerant in the cycle. It is possible to prevent the refrigerant temperature in the refrigeration cycle from becoming abnormally high, and reduce the risk of product failure.

In addition, the control unit 55 determines that the capacitance values of the plurality of operation switches 32a simultaneously exceed a predetermined value during the clothes drying operation, stops the heater 44, and rotates the sirocco fan 42 to a predetermined maximum air volume. After the air volume is driven, the operation is continued for a predetermined time longer than the predetermined operation time of the clothes drying operation. Since the heater 44 is stopped during the clothes dropping operation, the clothes drying efficiency in the clothes dropping operation is lower than that in the normal clothes drying operation. When the clothes dropping operation is started, the drying of the clothes hung on the housing 10 is accelerated by setting the operation time longer than when the normal clothes drying operation is continued, thereby preventing the clothes from being inadequately dried. can be prevented from occurring.
