Description

[Detailed Description of the Invention] This invention aims to increase the strength of a washing machine in which a washing tub and a dehydrating tub are integrally molded from synthetic resin.

With advances in synthetic resin molding technology, two-tub washing machines have simplified their construction by molding the washing tub and spin-drying tub into one piece of synthetic resin. If the parts are connected together, they are likely to be distorted during molding, and also when water is poured into the washing tub. In some cases, the positional relationship between the parts may be misaligned, causing noise and water leakage. Therefore, it was considered to solve these problems by arranging reinforcing plates at the bottoms of both tanks that fit into the drainage holes of both tanks. However, although this can suppress distortion in the same direction as the line connecting both drain ports, it cannot cope with twisting of both drain ports in a different direction.

This proposal improves the reinforcing function of the reinforcing plate.It will be explained based on the following diagram.1 is a two-tub washing machine that has a washing tub 3 and a dehydrating tub 4 in the machine frame 2, and the bottom part of the washing tub is is equipped with a pulsator 5, has a dehydration basket (not shown) in the dehydration tank 4, and has a control box 6 installed along the rear edge of the upper end. The washing tub 3 and the dehydration tub 4 are integrally formed of synthetic resin, and a folded piece 7 formed at the upper opening edge is locked to the upper edge of the machine frame made of iron plate. .

Cylindrical drainage ports 24 and 25 are formed protruding from the bottoms of the washing tub 3 and the dehydration tub 4, respectively. 26
is a triangular reinforcing plate, and two large diameter holes 27 and 28 bored in two corners of the plate are connected to each of the drain ports 24 and 28, respectively.
25 and this reinforcing plate 26 is brought into contact with the bottom surfaces of the washing tub 3 and the dehydrating tub 4, and the screw 30 is inserted through the small diameter hole 29 made in the remaining corner of this reinforcing plate. The reinforcing plate 26 is fixed by screwing into a boss extending vertically from the bottom of the washing tub 3. Note that the small diameter hole 29 may be directly fitted into the boss without using the screw 30. Further, this reinforcing plate 26 may be fixed to the dehydration tank 4 side. As a result, the fitting position of both drain ports 24 and 25 and the small diameter hole 29
A triangle can be formed between the fixed position or the fitted position, and the positional relationship between the drain ports 24 and 25 and the distortion during molding can be corrected while preventing twisting.
31 is a hose joint connected to the base end side of the drain hose 32, and has two connection ports 33 and 34, both of which are connected to the drain port 24 which is vertically connected to the washing tub and the dehydration tub respectively. , 25.

As described above, in this case, reinforcing plates 26 are attached to the cylindrical drainage ports 24 and 25 vertically installed from the washing tub 3 and the dehydration tub 4.
At the same time, this reinforcing plate 26 is provided to straddle between both tanks, and bosses and attachment holes are provided on the reinforcing plate 26 and both tanks to be attached to each other, and this attachment position is set between the two drains. Since it is located away from the straight line connecting the ports, the two drain ports 2 are connected by this reinforcing plate 26.
4 and 25 can be corrected, distortions that occur in the washing tub 3 and dehydration tub 4 during molding can be corrected by this reinforcing plate 26, and also when water is poured into the washing tub 3. This washing tub never becomes distorted. Therefore, no excessive force is applied to the pulsator drive shaft or dehydration basket drive shaft that penetrates the bottom of the washing tub or dehydration tub, increasing durability and eliminating the cause of water leakage. can.
