Fig. 3 is a plan view showing a wiring board 40 on which components (electrical and electronic components) of the electrical structure shown in Fig. 1 are mounted. In other words, in the right side portion of the wiring board 40, the first DC power supply circuit 50, the washing machine-13-200912082, the motor drive circuit 44, and the main microcomputer 6.8 are arranged in series, on the other side. In the left side portion, the second DC power supply circuit 57, the compressor motor drive circuit 46, and the sub microcomputer 49 are arranged in series. Therefore, the first DC power supply circuit 50, the washing machine motor drive circuit 44, and the main microcomputer are connected in series. The second DC power supply circuit 57, the compressor motor drive circuit 46, and the sub microcomputer 49 in the series state are arranged in a parallel state, and the wiring board 40 is used in the center portion of the noise filter 47 and the fan motor. Since the drive circuit 45 is placed in series, the noise filter 47 and the fan motor drive circuit 45 in the series state are disposed in the first DC power supply circuit 50, the washing machine motor drive circuit 44, and the main microcomputer 6 8 in series. The second DC power supply circuit 57 in the state, the compressor motor drive circuit 46, and the sub microcomputer 49 are provided. A power supply terminal portion 7 〇 ' is attached to an upper portion of a central portion of the wiring substrate 40. The power supply side terminal is connected to a single-phase AC power supply 4, and the load side terminal is connected to an input terminal of the noise filter 47.

When the AC power supply voltage from the single-phase AC power supply 48 is supplied to the first DC power supply circuit 50 via the noise chopper 47, the AC--14-200912082 source voltage is subjected to the full-wave rectification circuit 5 1 full-wave. It is rectified and smoothed by the smoothing capacitors 5 2, 5 3 'as a DC voltage supply voltage of a multiple voltage, which is generated between the two terminals 54 and 55 of the series circuit of the smoothing capacitors 52 and 53. Further, the DC power supply voltage of this multiple voltage is supplied to the washing machine motor drive circuit 44 via the current fuse 56. Moreover, when the AC power supply voltage from the single-phase AC power supply 4 8 is applied to the DC power supply circuit 57 of the open circuit 2 via the noise filter 47, the AC power supply voltage is subjected to the full wave of the full-wave rectifier circuit 58. The rectification is smoothed by the smoothing capacitors 5 9 and 60 , and the DC power supply voltage as the double voltage is generated between the terminals 6 1 and 62 of the series circuit of the smoothing capacitors 59 and 60 . Further, the DC power supply voltage of this multiple voltage is supplied to the compressor motor drive circuit 46 via the current fuse 63, and is supplied to the fan motor drive circuit 45 via the current fuse 64. The main microcomputer 68 is supplied with a DC control voltage obtained by stepping down the DC power supply voltage between the two terminals 5 4 and 5 5 of the series circuit of the smoothing capacitors 52 and 53 to start the operation, and the sub microcomputer 69 The DC control voltage obtained by stepping down the DC power supply voltage between the two terminals 61 and 62 of the series circuit of the smoothing capacitors 59 and 60 is given, and the operation is started, based on the control of the main microcomputer 68 and the sub microcomputer 69. , perform the following laundry drying operation. Initially, the operation of washing and washing using the control of the main microcomputer 68 is started. In this operation, the water supply valve 41 performs water supply to the water tank 2 via the water supply tank 42 and the water supply hose 43, and then the washing machine motor 14 is actuated to rotate the rotary groove 3 alternately in the forward and reverse directions at a low speed. When the washing operation is completed, the drying operation is then executed by the control of the sub-microcomputer 69 that has received the instruction of the main microcomputer 68 -15- 200912082. In this operation, the rotating groove 3 is rotated at a high speed, and then rotated at a low speed in both the forward and reverse directions, and the fan motor 29 of the fan 22 is actuated. Then, by the air blowing action of the centrifugal blade 28, as shown by the arrow in Fig. 2, the air 'in the water tank 2' flows from the warm air outlet 9 through the return air duct 20 of the air passage 27 and the connecting hose 21' to the ventilation duct 1 8 inside. Further, at this time, the compressor 32 of the heat pump 33 is driven by the compressor motor 35. Thereby, the refrigerant enclosed in the heat pump 3 3 is compressed to become a high-temperature high-pressure refrigerant, and the high-temperature high-pressure refrigerant flows to the condenser 3 1 ' to cause the condenser 31 to generate heat and exchange heat with the air in the ventilation duct 8 . As a result, the air in the ventilation duct 18 is heated, and conversely, the temperature of the refrigerant is lowered to be liquefied. The liquefied refrigerant then flows into the evaporator 3 0 ' and is vaporized. Thereby, the evaporator 30 cools the air in the ventilation duct 18. The refrigerant passing through the evaporator 30 is returned to the compressor 32. By these operations, the air that has flowed into the ventilation duct 18 from the inside of the water tank 2 is cooled and dehumidified in the evaporator 30, and then heated and warmed by the condenser 31. Then, the warm air is supplied to the water tank 2 through the connection hose 25 and the air supply duct 26, and is supplied from the warm air inlet 10 to the inside of the water tank 2, and is further supplied into the rotary tank 3 by the warm air guide inlet 36. The warm air supplied to the rotary tank 3 takes off the moisture of the laundry, and then flows out through the hole 39 or the opening 5 of the rotary tank 3, and then passes through the above-mentioned warm air outlet 9 through the return air duct 20 and the connecting hose 21. It flows into the ventilation duct 18. Thus, the laundry which is circulated in the rotary groove 3 between the ventilation duct 18 having the evaporator 30 and the condenser 31 and the rotary tank 3 by the air is dried. In the above-described laundry drying operation, the voltage detecting circuit 44 detects the input DC voltage of the washing machine motor driving circuit 44, that is, the DC voltage of the subsequent stage of the current fuse 56, and gives the detection voltage signal thereto. The main microcomputer 68. Therefore, for example, when the current fuse 56 is blown due to an overload or short circuit of the washing machine. The motor 14 is blown, the main microcomputer 6 8 determines that the current fuse 56 is blown, and the motor drive circuit 4 for the washing machine is stopped. 4 and the fan motor drive circuit 45, and the sub-microcomputer 69 is notified of the content 'stop the compressor motor drive circuit 46. The main microcomputer 6 8 performs the same operation as described above when the current fuse 64 on the side of the fan motor drive circuit 45 is blown. When the current fuse 63 of the compressor motor drive circuit 46 is blown during the operation of the washing and drying machine, the sub-microcomputer 69 notifies the main microcomputer 69 of the content. When the main microcomputer 69 receives the notification, the washing machine motor drive circuit 44 is stopped. The fan motor drive circuit 45 is stopped. The main microcomputer 6 8 monitors the sub microcomputer 6 during the washing and drying operation, and stops the washing machine motor drive circuit 44 and the fan motor drive circuit 45 when the sub microcomputer 69 is run away. According to the present embodiment, the first DC power supply circuit 50 is used as a dedicated DC power supply circuit for the washing machine motor drive circuit 44, and the second DC power supply circuit 57 is used as the compressor motor drive circuit 46 and the fan motor drive circuit 45. Common DC power circuit. Therefore, even in the washing and drying operation, the regenerative voltage is applied to the series circuit of the smoothing capacitors 52 and 53 by the regenerative braking of the washing machine motor, and the detection pressure between the two terminals 5 4 and 5 5 largely fluctuates. Also, it is not applied to the drive motor 45 of the fan motor -17-200912082. Unlike the prior art, the fan motor 29 does not generate a roar. Of course, the detection voltage between the two terminals 54 and 55 of the series circuit of the smoothing capacitor 52' 53 is not applied to the compressor motor drive circuit 46 and is supplied to the fan motor drive circuit 45. As shown in FIG. 3, the DC power is drawn from the terminals 61 and 62 of the smoothing capacitors 59 and 60. Therefore, even if a large current flows through the compressor motor 35, the compressor motor is connected to the wiring substrate 40. The voltage fluctuation occurs in the wiring pattern of the drive circuit 46, and this voltage fluctuation does not affect the DC power supplied to the fan motor drive circuit 45. Further, the noise filter 47, the first and second DC power supply circuits 50, 57, the washing machine motor drive circuit 44, the compressor motor drive circuit 46, the fan motor drive circuit 45, the main microcomputer 68, and the sub microcomputer 69 are The first DC power supply circuit «50, the washing machine motor drive circuit 44, and the main microcomputer 68 are arranged in series, and the second DC power supply circuit 57 and the compressor motor drive circuit 46 are mounted on the same wiring board 40. The sub-microcomputer 69 is placed in a series state, and the first DC power supply circuit 50, the washing machine motor drive circuit 44, and the main microcomputer 68 are arranged in parallel, and the noise filter 47 and the fan motor drive circuit 4 are arranged in parallel. 5 is arranged in a series state and is disposed between the first DC power supply circuit 5, the washing machine motor drive circuit 44, the main microcomputer 6 8 and the second DC power supply circuit 57, the compressor motor drive circuit 46, and the sub microcomputer 69. Therefore, the electric and electronic components constituting each of the circuits can be arranged reasonably, and the wiring can be simplified. The fan motor drive circuit 45 does not need to be provided with a dedicated DC power supply circuit of -18*200912082, and the wiring board 4 can be made small.

Further, the output terminal of the first noise filter 47A is connected to the AC input terminal of the full-wave rectifier circuit 5 1 of the first DC power supply circuit 50, and the output terminal of the second noise filter 47B is connected to the second DC power supply circuit. In the second embodiment, the control input/output terminal of the fan motor drive circuit 45 is not connected to the main microcomputer 6.8, but is connected to the sub microcomputer 69. The input and output ports of the voltage detecting circuit 66 are also connected to the input port of the sub microcomputer 61. Therefore, the fan motor drive circuit 45 performs the same control as that of the first embodiment by the sub microcomputer 69 in accordance with an instruction from the main microcomputer 68.
