[Example 1]

FIG. 1 is an external perspective view of the washer-dryer 100, and FIG. 2 is a right side sectional view of the washer-dryer 100. FIG. According to FIG. 1, the washing machine 100 includes a casing 1 constituting an outer frame, a top cover 2 is provided on an upper portion of the casing 1, and a base 3 is provided on a lower portion of the casing 1. Four feet are provided on the base 3, of which a height-adjustable adjusting leg 3a is provided at one point facing the front right of the washing machine body, and the other three are provided with fixed legs 3b that cannot be adjusted in height. When installing a washing machine, adjust the tilt of the main body by adjusting the height of the adjusting foot 3a Or the display is rattling unevenly. Moreover, the top cover 2 is provided with the outer cover 2b which can cover the clothing insertion opening 2a. An operation panel 7 including a power switch 4 or an operation switch 5, and a display 6 is provided on the front side of the top cover 2. The operation panel 7 is electrically connected to a control device 14 provided on the back surface of the casing 1.

Inside the casing 1, an outer tank 10 storing water is elastically supported by the casing 1 through four corners through a suspension rod. An air vent pipe 21a is provided on the back of the outer tank 10, and the internal pressure is transmitted to the water level sensor 21 via the pipe 21b to detect the water level of the water that has been accumulated in the outer tank 10. A safety switch 31 is provided at the front corner of the housing 1 as a structure for detecting when the outer tank 10 vibrates during dehydration, when it becomes a predetermined vibration displacement or more.

An inner tank 8 is provided inside the outer tank 10 to receive clothing. The inner groove 8 includes a plurality of small through holes 8a for passing water and ventilation on its outer peripheral wall, and a plurality of through holes 8b for passing water and ventilation on its bottom wall, and is provided on its upper edge portion. A fluid balancer 9 is provided, and the rotary wing 11 is rotatably supported inside the bottom.

A motor 13 is provided on the outside of the bottom of the outer tank 10, and the clutch mechanism 12 is controlled to cause the rotation of the inner tank 8 and the rotary wing 11 to operate as described below. One is to lock the inner groove 8 to make it stand still, or to release the inner groove 8 to allow it to rotate freely. By rotating the rotary wing 11 to repeat the forward and reverse rotation, it is mainly used to make clothing. Stir occasions. The other is an operation in which the inner tank 8 and the rotary wing 11 are integrated and rotated in the same direction, and is mainly used in the case of dehydration.

A groove shell cover 23 is provided on the upper surface of the outer groove 10, and the groove shell The cover 23 includes a clothing input port 23a, a warm air blowing port 23b, and a water supply inlet 25a that communicate the upper and lower surfaces. In addition, the tank cover 23 is provided with an inner cover 24 for covering the clothes inlet 23a, and can be opened and closed by a hinge 24a. The inner cover 24 is opened by lifting the handle 24b upward, and the lock is released and locked by pressing downward.

A drying vent pipe 10c is provided on the rear side of the outer tank 10. The drying vent pipe 10c is connected to the drying unit 19 via a telescopic hose 10d. The drying unit 19 includes a heater 19b as a heat source of the fan 19a, and a temperature sensor 19c. The drying unit 19 is connected to a warm air outlet 23b provided in the tank cover 23 via a telescopic hose 23c. The fan 19a circulates the air whose temperature is raised by the heater 19b to dry the clothes. In addition, a water supply solenoid valve 25 connected to the water supply port 2c is provided in the housing 1 and can supply water to the inner tank 8 or the drying vent pipe 10c. A drain port 10 b for draining water is provided at a lower portion of the outer tank 10, and a drain pipe 24 is connected via a drain valve 15.

The fluid balancer 9 provided in the upper part of the inner tank 8 is formed in a ring shape from a synthetic resin or the like, and has a plurality of flow paths inside. Liquid is enclosed in these flow paths, and when vibration occurs during dehydration, it has the effect of reducing vibration. Specifically, when vibration occurs due to clothing bias (hereinafter referred to as imbalance) during dehydration, if the number of rotations is higher than the number of resonance rotations, the phase will deviate 180 degrees from the direction of imbalance. In the direction of vibration. At this time, the liquid in the fluid balancer 9 is biased in the direction of vibration. That is, as for the imbalance, the positional deviation of 180 degrees in the orientation can cancel the imbalance and reduce the vibration.

FIG. 3 is the tank cover 23 and the inside viewed from the back side (below) A perspective view of the cover 24. On the back side of the tank cover 23, convex portions 50a and 50b having a convex shape for suppressing the clothes from being caught are provided. The convex portion 50 a is provided on the front side of the tank case cover 23, and the convex portion 50 b is provided on the rear side of the tank case cover 23.

Fig. 4 is a view of the tank cover 23 and the inner cover 24 as viewed from the outer side (upper side); Fig. 5 is a cross-sectional view taken along the line AA 'of the washer-dryer 100 in Fig. 4. The enlarged view of the area enclosed by X in Fig. 5 (the front side of the washer-and-dryer) is shown in Fig. 6; the area enclosed by Y in Fig. 5 (the back side of the washer-and-dryer) The enlarged view is shown in Figure 7.

As shown in FIG. 6, since the convex portion 50 a having a convex shape closer to the center side than the fluid balancer 9 is provided on the back side of the tank cover 23, it is possible to reduce the possibility that clothing is caught between the fluid balancer 9 and the groove. The cover 23 is damaged. In the case of dehydration or the like, the clothing can be pulled into the inner groove 8 by the convex portion 50a, as shown in the direction of the arrow in FIG. 6, against the inclined surface 9b of the fluid balancer 9. Therefore, it is preferable that an inclined surface is also provided on the inner peripheral side of the convex portion 50a.

A gap S is provided between the fluid balancer 9 and the convex portion 50a. Thereby, interference between the fluid balancer 9 and the convex portion 50a caused by the inclination of the outer tank 10 during dehydration or the like can be suppressed.

In addition, the convex portion 50 a can be more effectively suppressed from being caught by the clothing by extending downwardly than the upper bottom 9 a of the fluid balancer 9. However, in terms of ensuring the capacity, it is preferable that the convex portion 50 a is positioned above the bottom of the fluid balancer 9. Moreover, by providing the convex portion 50 a slightly above the inclined surface 9 b of the fluid balancer 9, clothing can be effectively brought into contact with the inclined surface 9 b of the fluid balancer 9 and can be pulled into the inner groove 8.

This is explained using FIG. 7. A convex portion 50b is provided on the back side of the tank cover 23 on the rear side of the washer-dryer. The major difference from FIG. 6 is that the length L2 of the convex portion 50b in the circumferential direction with respect to the rotation axis of the inner groove 8 is longer than the length of the convex portion 50a. That is, as shown in FIG. 3, the area of the convex portion 50 is larger on the rear side of the tank cover 23 than on the front side. This is because the convex portion 50 is provided in as many areas of the tank cover 23 as possible, and the effect of suppressing the pinching of clothing can be expected more, and the area of the rear side of the tank cover 23 is due to the configuration of the drying unit 19 and the like. Relationship.

The other structures and the like are the same as those in FIG. 6, and therefore descriptions thereof are omitted.

According to the above embodiment, it is possible to provide a convex portion 50 having a convex shape closer to the center side than the fluid balancer 9 on the back side of the tank cover 23, which can suppress the increase in cost while suppressing the pinching of clothing Washer and dryer.
