Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a two-tub washing machine with a dehydrator for general household use.

Conventional configuration and its problems Below, the conventional washing machine of this type is shown in Figure 1.
This will be explained using FIG.

In Figures 1 and 2, 1 is a washing tub with rotary blades (not shown) on the inner bottom, 2 is a dehydration tank with a rotatable dehydration basket inside, and washing tub 1 and dehydration tub 2 are They are integrally formed of synthetic resin with a common partition wall 3 interposed therebetween. A dewatering hatch 6 having a laundry entrance/exit 5 in the upper opening 4 of the dehydrating tank 3 is held between an outer peripheral flange 7 of the dehydrating hatch 6 and a rib 8 integrally formed on the dehydrating hatch 6. It was attached to the upper end of the common bulkhead 3.

However, according to the above configuration, when hot water is poured into the washing tub 1, the common partition wall 3 becomes undulating due to deformation due to thermal expansion, and the ribs 8 and flange portions 7 are no longer able to hold the common partition wall 3, causing dehydration. The hatch 6 would lift up or become impossible to attach, making it extremely dangerous for the user during dehydration.

Purpose of the invention In view of the above-mentioned conventional problems, the present invention provides a safe two-tub washing machine in which the dewatering hatch does not float up.

Structure of the invention The two-tank washing tub of the invention integrally forms a washing tub with rotary blades on the inner bottom and a dehydration tank with a rotatable dehydration basket inside, and an upper opening of the dehydration tank. A dehydration hatch having an entrance and exit for laundry is provided in the dehydration hatch, and the dehydration hatch is provided with an outer periphery flange portion and a rib that clamps the partition wall between the dehydration tub and the washing tub together with the flange portion, and the rib is connected to the dehydration tub. When the common partition wall contracts due to a temperature change, the ribs and the flange portion of the dewatering hatch serve as a support to prevent the common partition wall from waving.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

In FIGS. 3 and 4, 9 is a washing tub in which rotary blades 10 are rotatably arranged on the inner bottom, 11 is a dehydrating tank in which a dehydrating basket 12 is rotatably installed, and the washing tub 9 and the dehydrating tank are 11 is integrally formed of synthetic resin (for example, polypropylene) with partition walls 13 in between. The upper opening 14 of the dehydration tank 11 is provided with a dehydration hatch 16 provided with an inlet/outlet 15 for laundry, and the dehydration hatch 16 has a flange portion 17 on the outer periphery, and a portion of the flange portion 17 on the washing tub 9 side. Ribs 18 are provided opposite to each other, and the horizontal length a of the ribs 18 is approximately equal to the horizontal length b of the partition wall 13. In addition, the dehydration tank 11 has the partition wall 13
Grooves 19 and 20 are provided in the vertical direction along the
The rib 18 is used as a rail when inserted.

In the above configuration, when the dewatering hatch 16 is attached, the partition wall 13
and is held by the ribs 18. Further, since the horizontal length a of the rib 18 is approximately equal to the horizontal length b of the partition wall 13, the rib 18 is press-fitted into the dehydration tank 11. Furthermore, the rib 18 is held between the partition wall 13 and the grooves 19 and 20.

This prevents the common partition wall 13 from waving due to temperature changes due to the ribs 18, and the ribs 18 are held by the dehydration tank 11, and are further held by the grooves 19, 20 and the partition wall 13. Therefore, even if the partition wall 13 tries to wave, the dewatering hatch 16 will not float up, making it safe.

In the above embodiment, the rib 18 is provided on the dewatering hatch 16.
The upper part of the common partition wall 13 has a double structure, but the ribs 18 are lengthened in the vertical direction to form the common partition wall 1.
It goes without saying that the entire surface of 3 may have a double structure.

Effects of the Invention As is clear from the description of the above embodiments, according to the present invention, the ribs provided on the dehydration hatch can prevent the undulation of the common partition between the washing tub and the dehydration tank, and the undulation of the common partition , the dehydration hatch will not float up, ensuring the safety of the user.
