In addition, a path through which hot air circulates is configured.

  The outer tub 3 is provided with an outer tub cover 17 that hermetically covers the upper surface, and the outer tub cover 17 is provided with an outlet 18 of a blowing path from the drying upper bellows-shaped hose 16. Further, the outer tub cover 17 is provided with an inner lid 19 that can be opened and closed so that clothes can be taken in and out.

  The case cover 20 covers the upper part of the case 1, has an openable / closable lid 21, is provided with a control device 22, and is provided with a water supply valve 23 for supplying water to the inner tank 4. The water supply valve 23 is watertightly coupled to the outer tank cover 17 via a water supply upper bellows-shaped hose 24 that is a water supply path, and an outlet 25 of the water supply path is opened in the outer tank cover 17. A water supply / discharge part 26 is attached to the outlet 25 of the water supply path from below the outer tank cover 17.

  As shown in FIG. 13, the water supply / discharge section 26 is attached by screws 27 from below the outer tank cover 17. A water reservoir 29 is provided by a rib 28 below the outlet 25 of the water supply path. Next to the water reservoir 29, a water supply unit 30 is provided via a rib 28. A plurality of water supply holes 31 are provided at the bottom of the water supply unit 30.

  The heat exchange blowing means 32 is provided inside the housing 1 and cools the outer tub 3, the heat exchanger 10, and the like by blowing air.

It is comprised so that each process of may be controlled.

  The operation in the above configuration will be described. In the washing process, in a state where the drainage side of the circulation path switching and drain valve 11 is closed, the opening / closing lid 21 and the inner lid 19 are opened, the laundry and detergent are put into the inner tub 4, and the operation is started. 22 opens the water supply valve 23 to supply water.

  Here, the flow of water at the time of water supply will be described. The water flowing out from the water supply valve 23 reaches the outlet 25 of the water supply path provided in the outer tank cover 17 through the water supply upper bellows-shaped hose 24 which is the water supply path. . Thereafter, the water falls to the water reservoir 29 at the bottom of the water supply discharge part 26, and the water overflowing from the water climbs over the rib 28, reaches the water supply part 30, and is discharged into the inner tank 4 from the plurality of water supply holes 31. The At this time, by setting the number, shape, direction, and the like of the plurality of water supply holes 31 to be predetermined, the water discharge direction can be set relatively easily, and the appearance of the water discharge shape is improved. Can be adjusted as follows.

  For example, as the direction of water discharge, by setting the direction near the inner wall of the inner tub 4 and so as to spread in a shower shape, at the time of rinsing, water is supplied while rotating the inner tub 4 and shower rinsing is performed. Can be executed.

  After supplying water to a predetermined water level, the motor 8 is driven. The power of the motor 8 is transmitted to the rotary blade 6 via the clutch 9 and the washing shaft 5a of the transmission mechanism. The clothes are agitated by the rotation of the rotary blades 6, and mechanical force acts on the clothes due to contact between the clothes and between the clothes and the inner wall of the inner tub 4 and the rotary blades 6, and washing is performed by the mechanical force and the washing power of the detergent. Is called.

  In the dehydration process, after washing is completed, the drainage side of the circulation path switching and drainage valve 11 is opened to discharge the water in the inner tub 4, and then the clutch 9 of the transmission mechanism is switched to the dehydration side. The power of the motor 8 is transmitted to the inner tank 4 via the dehydrating shaft 5b. The centrifugal force generated by the rotation of the inner tub 4 is applied to the clothing, and water is separated from the clothing, so that dehydration is performed.

  At this time, in the water reservoir 29 at the bottom of the water supply discharge part 26, water 33 at the time of water supply is collected up to the vicinity of the tip of the rib 28 before dehydration. Overcoming the rib 28, reaching the water supply section 30, passing through the water supply hole 31 at the bottom, dropping into the inner tank 4, being discharged into the outer tank 3 by dehydrating rotation of the inner tank 4, and the water surface of the water 33 is It becomes lower than the front end surface, and the amount of water pool can be increased.

  Therefore, even if the residual water 34 remaining in the water supply upper bellows-like hose 24 becomes water droplets and drops into the water reservoir 29 during dehydration, after dehydration, or when taking out clothes, the water reservoir 29 Is not accumulated in the inner tank 4.

  In the drying process, first, the clutch 9 is switched to the washing side, and the power of the motor 8 is transmitted to the rotary blade 6. By rapidly rotating the rotor blade 6 forward and backward, the clothes attached to the inner wall of the inner tub 4 are peeled off by the centrifugal force of dehydration. Next, warm air is sent to the outlet 18 of the ventilation path by the blowing means 13 and the heater 14 while rotating the rotating blade 6 forward and backward to stir the clothes. The warm air blown into the inner tub 4 from the outlet 18 of the air blowing path evaporates moisture from the clothing, then exits from the inner tub 4 to the inner side of the outer tub 3, passes through the lower bellows-like hose 12, It reaches the exchanger 10.

  When the warm air containing moisture from the clothing deprived of moisture passes through the inner wall of the outer tub 3 or the heat exchanger 10, the external air is blown out by the heat exchange blowing means 32 installed on the side surface of the housing 1. The outer wall of the outer tub 3 and the heat exchanger 10 is cooled by the inflow. By this cooling, moisture condensation occurs inside, and the moist warm air is dehumidified and returned to the blowing means 13. By circulating hot air through this circulating path, the clothes in the inner tub 4 can be dried.

At this time, dry steam is generated in the inner tank 4 and the steam enters the water supply upper bellows-like hose 24 serving as a water supply path. The steam condenses inside the water supply upper bellows-like hose 24 to generate condensed water. The condensed water collects into large water droplets and falls into the water reservoir 29, but only accumulates there and does not fall into the inner tank 4. At this time, the water 33 in the water reservoir 29 is dried and evaporated by the temperature of the warm air in the inner tank 4, and the water surface of the water 33 becomes lower than the tip surface of the rib 28, thereby increasing the allowable amount of the water reservoir. Therefore, even if the water droplet falls into the water reservoir 29, it does not get over the rib 28 and reach the water supply unit 30.
