Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a single-tank dehydrating washing machine that has a washing/dehydrating tank inside the washing receiving tank and a stirring plate provided at the center of the bottom of the washing/dehydrating tank. It is something.

[Prior art]

Conventionally, in this single-tank dehydrating washing machine, as shown in FIG.
When supporting it elastically, wash it! ! ! A vibration-proof support mechanism part 3 is installed at a suitable place on the bottom of the monk 1 or on the side surface of the outer chamber. : The receiver is reinforced and fixed with a hanging metal part 4 so as to withstand the static or dynamic load of the internal mechanism of the washing machine. This has disadvantages such as an increase in the number of parts and higher manufacturing and assembly costs, and the need for strength in the metal fittings themselves, which increases material costs.

Further, as shown in FIG. 3, in the case where the washing tub 1 and the hanging fitting part 4 are integrally molded from synthetic resin, in order to reinforce the anti-wrinkle support part 5 corresponding to the hanging fitting part 4, There is also a reinforcing part 6 that is integrally molded to sandwich the receiving part 5 and reinforcing only the lower part of the receiving part or the upper and lower parts of the receiving part, but it is used at a water temperature of about 60 C when washing. There is almost no problem when using the water at a temperature of 80C, but if you use the toilet for a long time, the washing tank (-J
: Creep deformation occurs due to thermal stress, for example, part 1a of the washing tub (the end point of the reinforcing part 6) is warped inward, and the gap G between the washing/drying tub 10 and the washing tub 4v1 is narrow.
Among objects with a large amount of deformation, there are cases where G=O. Therefore, depending on the size of unbalanced laundry or its position during dewatering, the washing/dehydrating tank 10 may be replaced by the washing receiving tank 1.
This may cause an abnormal noise or the dehydration rotation may become locked, and the problem may even develop into an increase in the temperature of the motor 11.

[Purpose of the invention]

The present invention was devised in view of these points, and an object of the present invention is to provide a laundry receptacle that can keep the amount of thermal deformation small even when used under high temperature conditions for a long time, and that can be washed without any trouble during actual use. Single-tank dehydration/4I
The purpose is to provide one aircraft.

[Summary of the invention]

The present invention was conducted to find out that the laundry receptacle of a single-tub dehydrating washing machine, in which the hanging metal part is integrally molded, undergoes creep deformation under long-term high-temperature use, resulting in the cap G of the laundry receptacle and the washing/dehydrating tub becoming narrower. In order to keep this creep deformation to an extremely small level so that it does not cause problems in actual use, we installed two vertical reinforcing sections on the sides of all washing tubs that sandwich the bearing section that receives the anti-fitting support mechanism section. is extended from the top to the bottom, and multiple horizontal reinforcing parts spanning between these two IM reinforcing parts are also integrally molded from synthetic resin, and the strength is increased especially near the bearing part where bending moment is applied. The pitch of the lower horizontal reinforcing parts is made smaller in order to reduce the bending moment, and the pitch of the horizontal reinforcing parts is made larger in the upper part, which is less affected by the bending moment.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes a washing tank, in which water is collected for washing or rinsing. Reference numeral 2 denotes an outer frame and a three-piece anti-vibration support mechanism section, which is supported by a bearing section 5 formed integrally with the washing tub 1 and suspended from the outer frame 2. Reference numeral 8 denotes an internal mechanism, which includes a stop device and a motor 1 that control the rotation speed of the agitation #12 during washing and the rotation speed of the washing/dehydration tank 10 during spin-drying.
Contains 1. Therefore, in this configuration, the maximum load applied to the bearing part 5 is (washing tank 1 and the water inside it) + (washing and dehydration tank) + (internal mechanism part) 60.-80 ni. When supporting in multiple places, one bearing part 5 has
Approximately 15-20 to 9 loads will be applied. Although the calculation of the bending moment and stress due to this load is omitted,
The point of the present invention is to disperse this bending moment and stress and to minimize the amount of creep deformation of the washing 7M receiving tank 1. In other words, the vertical reinforcing part 6 that sandwiches the bearing part 5 is extended to the top of the wash/hiro holder 4v#1 with a height of 1 height, and the horizontal reinforcing part 9 that spans between these two vertical reinforcing parts 6 is also integrated. By molding, the section modulus Z of the reinforcing portion supporting the bearing portion 5 can be increased and the stress can be reduced. In addition, as shown in Figure 4, the pitch eP+ (lower part) of the horizontal reinforcement part
By setting <pt (upper part), the stress due to the load applied to the bearing portion 5 can be significantly reduced.

In one embodiment of the present invention, the horizontal reinforcing part 9 is fixed only within the vertical reinforcing part 6, but the horizontal reinforcing part 9 may extend outside the vertical reinforcing part 6, and to put it simply, it can extend outside the washing tub 1! If it is reinforced in a round shape, the rigidity of the laundry receptacle 1W1 will further increase and it will be strong against thermal stress.

〔Effect of the invention〕

According to the present invention, there is provided not only a scale that eliminates the need for the conventional hanging fittings that require strength, the number of parts is reduced, and improves workability and productivity, but also a laundry receptacle that is lightweight and highly reliable against thermal stress. can do.
