Description

  The present invention relates to a washing machine that automatically controls a series of steps such as washing, rinsing, and dewatering.

  Conventionally, this type of washing machine has various setting buttons such as a button for setting a washing time, the number of times of rinsing, and a dehydrating time in the operation display section, and a button for setting a driving course, and the setting contents and start of operation The structure of the display part which displays the remaining time from is proposed (for example, refer patent document 1).

  FIG. 6 is an operation display unit of a conventional washing machine described in Patent Document 1.

  In FIG. 6, when the user turns on the power and presses the wash button 130b, for example, the wash LED 134b is turned on and the washing time can be set, and when the rinse button 130c is pushed, the rinse LED 134c is turned on and the number of times of rinsing is set. If the dehydration button 130d is pressed, the dehydration LED 134d is lit and the dehydration time can be set. Alternatively, the centrifugal course LED 134i or the stirring course LED 134h is turned on by pressing the washing / drying fully automatic button 130g of the special operation course which is an automatic operation, and the operation course can be set. Then, if the start button 130e is pressed after various settings, the operation starts.

  When the operation starts, first, a rotating drum (not shown) rotates little by little to detect the amount of laundry put in the tub. When the amount of cloth is detected, one of the water level LEDs 134a is turned on and a water level corresponding to the cloth amount is displayed, so the user puts the amount of detergent that matches the water level into a detergent case (not shown). be able to. Thereafter, water supply starts, the remaining time until the end of the operation is displayed on the digital display 134e, and the stroke operation proceeds.

A motor 3 is attached to the rear surface of the aquarium 2 to rotate the rotating shaft of the drum 1 while tilting it forward. The drum 1 is rotated by driving the motor 3, and the clothes put in the drum 1 are stirred. Swipe and dry.

  A door body 35 is provided at the front of the housing 100 so as to face the opening end side of the drum 1, and the user opens the door body 35 so that laundry (clothing) is applied to the drum 1. Can be put in and out. In addition, a water supply pipe (not shown) provided with a water supply valve 134 (see FIG. 3) and a drain pipe 40 provided with a drain valve 27 are connected to the water tank 2.

  Below the water tank 2, a damper 14 is provided that supports the water tank 2 and attenuates vibrations of the water tank 2 caused by clothing bias in the drum 1 during dehydration. The damper 14 is provided with a cloth amount detection unit 15 that detects the amount of clothing by detecting the amount of displacement of the shaft of the damper 14 up and down due to the weight change caused by the clothing in the water tank 2 to be supported. .

  In order to dry the clothes, the air in the water tank 2 and the drum 1 is circulated by the blower unit 4. The air that has taken moisture from the laundry in the drum 1 is in the water tank 2. Is discharged to the heat pump device 50 part outside the drum 1.

  The heat pump device 50 includes a compressor 16 that compresses a refrigerant, a heating unit (radiator) 17 that radiates heat of the refrigerant that has been compressed to high temperature and pressure, and a throttle unit that depressurizes the pressure of the high-pressure refrigerant. 18, a dehumidifying part (heat absorber) 19 that draws heat from the surroundings by the reduced pressure and low pressure refrigerant, and a pipe line 20 that connects these four members to circulate the refrigerant and is discharged. The drying air is dehumidified by a dehumidifying section (heat absorber) 19. The drying air dehumidified by the dehumidifying part (heat absorber) 19 is heated by the heating part (heat radiator) 17. The heated drying air is led from the air blowing section 4 disposed in the middle of the circulation air path 13 to either the first air path 9 or the second air path 11 located downstream of the air blowing section 4, Blow out into drum 1 again.

  Here, the first air passage 9 has a first air outlet 8 opened to the rear of the drum 1. On the other hand, the second air passage 11 has a second air outlet 10 opened at the upper front portion of the drum 1.

The working air can be blown into the drum 1.

  Further, the second air outlet 10 of the second air passage 11 has an air passage cross-sectional area smaller than that of the first air outlet 8, and high-pressure and high-speed drying air in the drum 1 as compared with the first air outlet 8. Can be blown out.

  Usually, in the case of a drum-type washing machine, the gap between the front of the rotating drum 1 and the water tub 2 is formed as small as possible so that clothes are not caught. Therefore, although it is difficult in terms of space to provide a small opening with a small opening and a small pressure loss in the small gap, the second blowing outlet 10 that blows off high-pressure and high-speed wind with a relatively small air passage cross-sectional area is provided. It can be provided. On the other hand, the bottom of the back of the drum 1 has a space for providing the first air outlet 8 having a relatively large opening.
