【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Components having the same configuration as the conventional example are denoted by the same reference numerals, and description thereof is omitted.
[0022]
As shown in FIG. 1, the outer tub cover 36 is formed in a substantially donut shape and disposed on the upper opening side of the outer tub 3, and the inner tub cover 36 is formed so as to open and close the inner opening of the outer tub cover 36. A lid 37 is provided. An outer frame cover 39 is provided on the upper portion of the outer frame 38, a drying blower 40 is provided inside the rear of the outer frame cover 39, and one end thereof communicates with the outside of the machine through an intake filter 41. The other end is connected to a hot air supply path 43 having a heater 42 to constitute a hot air supply means 44. The hot air supply passage 43 is connected to a blowing bellows hose 45, and is configured to supply hot air into the inner tank 4 from a hot air supply port 46 provided in the outer tank cover 36.
[0023]
The outer tank cover 36 is provided with a water supply section 49 connected to a water supply valve 47 and connected to a water supply pipe 48 for supplying water into the inner tank 4 so that the water supply section 49 receives residual water from the water supply pipe 48. A residual water reservoir 50 is provided.
[0024]
In the outer tank cover 36, an exhaust port 51 for exhausting the hot air supplied from the hot air supply port 46 into the inner tank 4 is formed, and the vicinity of the residual water reservoir 50 is dried by exhausting the hot air. It is configured as follows. Here, the water supply unit 49 also serves as a part of the exhaust port 51 communicating with the outside of the outer tank cover 36, and the residual water storage unit 50 is located in the middle of the exhaust path of the warm air sent into the inner tank 4. It is configured as follows.
[0025]
A support member 52 is fixed near the exhaust port 51, and an exhaust filter 53 is detachably attached to the support member 52 so as to cover the exhaust port 51.
[0026]
The operation of the above configuration will be described. The operation from the washing step to the dehydration step is the same as the operation of the conventional example, and the description is omitted.
[0027]
When the drying process starts, the drain valve 28 is closed and the clutch 12 is switched to the washing side. Then, the motor 11 is driven to transmit the rotation to the rotating blades 6, the rotating blades 6 are rotated forward and inverted, and the clothes are hooked and stirred by the stirring protrusion 10. Further, the drying blower 40 and the heater 42 are energized to change the outside air sucked through the intake filter 41 into warm air, and the warm air is blown into the inner tank 4 from the warm air supply port 46 as indicated by an arrow. After the warm air warms the clothes under stirring and evaporates water from the clothes, the warm air rises toward the upper part of the inner tank 4 and is discharged from the exhaust port 51.

Therefore, at the time of drying, the residual water remaining in the water supply pipe 48 at the time of washing may drip into the residual water storage part 50 provided in the water supply part 49. Since the drying is performed by the warm air of the exhaust gas, it is possible to prevent the residual water from dropping onto the clothing during the drying or at the end of the drying to wet the clothing.
[0029]
Further, since the water supply unit 49 also serves as a part of the exhaust port 51 communicating with the outside of the outer tub cover 36, it is possible to dry the residual water remaining in the water supply pipe 48 at the time of supplying water, and to dry clothes. Water can be prevented from dripping into the water supply unit 49 and the lint may adhere to the water supply unit 49, the residual water storage unit 50, and the like during drying. However, since water is supplied during washing, the water supply unit 49 and the residual water The lint adhering to the reservoir 50 or the like can be washed away.
[0030]
Further, since the residual water reservoir 50 is located in the middle of the exhaust path of the warm air sent into the inner tank 4, the residual water remaining in the water supply pipe 48 at the time of water supply can be dried, and the residual water can be added to the clothes when drying. Of water can be prevented from dropping.
