Description

[Detailed description of the invention] The present invention relates to a washing machine that performs both washing and rinsing processes and dehydration processes in a washing and dehydration tank.The purpose of this invention is to The purpose is to quickly discharge the remaining sand and other debris to the outside with a simple operation.

In a conventional washing machine of this type, the structure for discharging sand and the like remaining in the washing/dehydration tank after the washing process etc. is as shown in FIG. 1.

In the figure, 1 is a washing and dewatering tank, 2 is a pulsator placed in a pulsator installation recess 1a provided at the bottom of the tank 1, 3 is a sand cultivation hole provided in communication with the recess 1a, and 4 is a pulsator. This is a plug that is screwed into this sand cultivation hole 3.

In the above configuration, the pulsator 2 in the washing and dehydrating tub 1 rotates during washing, and the washing and dehydrating tub 1 itself rotates during dehydration.

Therefore, when draining sand and the like accumulated in the washing and dewatering tank 1, it is difficult to adopt a structure that can be easily opened and closed by an external operation like a general drain cock.

According to the above-mentioned configuration, the plug body 4 is rotated by a screwdriver or the like and the screws are released to remove the plug body 4 and discharge sand, etc., so that the plug body 4 can be removed. The work was troublesome, and the work when reattaching it was also troublesome.

Additionally, there was a possibility that the removed plug body 4 might be forgotten to be reattached, and there was also a risk that it would be lost.

The present invention solves the above-mentioned conventional drawbacks, and examples thereof will be described below.

In Figures 2 to 5, the washing and dehydration tank 1 has a non-porous peripheral wall except for at least the upper end, and all drainage during dehydration and washing occurs as the tank 1 rotates. Due to the release of water by centrifugal force from the upper open end.

Further, although this tank 1 is not shown, it is housed in a water receiving tank, and this water receiving tank has a discharge channel for discharging dehydrated liquid and the like to the outside of the machine.

5 communicates with the recess 1a for pulsator arrangement and
This is a recessed part provided so as to be connected to the lowest part of the slope at the bottom part 1b of the road surface.

Reference numeral 6 denotes a hole bored at the bottom of the concave portion 5 so as to communicate between the inside and outside of the washing and dehydrating tank 1.

Reference numeral 7 indicates a connecting portion between the recessed portion 1a and the recessed portion 5.

Reference numeral 8 denotes a lattice-shaped support whose upper end is connected to the lower surface of the washing and dewatering tank 1, and one end of a spring member 9 is disposed inside the lower end side, and the other end of the spring member 9 is pressed. Materials suitable for ensuring liquid tightness, such as rubber materials.

A plug 10 made of a highly visible resin material or the like is attached.

This plug body 10 is pressed and biased by a spring member 9 so as to always close the hole 6. Specifically, in the closed state, the peripheral flange portion 10a of the plug body 10 closes the hole 6. The biasing force of the spring member 9, which is in pressure contact with the peripheral edge of the end face, is such that the plug body 10 does not open the hole 6 even if it receives water pressure when washing water is contained in the washing/drying tub 1. The plug body 10 is opened by pressing the plug body 10 from inside the washing/dehydration tank 1 with a finger or the like against the biasing force of the spring member 9.

This suppression continues until sand and the like accumulated in the inner bottom of the washing and dewatering tank 1, the pulsator installation recess 1a, etc. are discharged to the outside from the hole 6.

Continuing to press down on the plug 10 with your fingers or the like is expected to make your posture uncomfortable. For example, if you press the plug 10 once, it will remain open, and if you press it again, it will close. An engagement/disengagement mechanism that returns to the state may also be used.

According to the above structure, by simply pressing the stopper 10, foreign matter such as sand remaining at the bottom of the washing/dehydration tank 1 can be discharged to the outside of the tank 1, which is different from the conventional stopper. Unlike those that are screwed together, the ejection operation is time-consuming and does not require tools such as a screwdriver.
It is extremely easy to use.

In addition, the plug body 10 is not separated from the tank 1, and the plug body 10 is not separated from the tank 1.
There will be no inconvenience such as forgetting to add 0 or losing it.

Further, since the foreign matter accumulated in the pulsator installation recess 1a reaches the recess 5 along the slope of the bottom surface, the foreign object can be quickly and reliably discharged. Since M is performed reliably, it is possible to prevent foreign matter from getting caught in the pulsator 2.

In addition, since the structure includes the plug body 10, the spring member 9, the support body 8, etc., it is not complicated and is advantageous in terms of cost.

As described above, according to the present invention, foreign matter such as sand remaining in the washing/dehydration tank can be reliably discharged out of the tank by simply pressing the stopper, thereby preventing foreign matter from adhering to the laundry. Also,
Inconveniences such as the pulsator getting caught in this foreign matter can be prevented.

Further, in terms of structure, it is sufficient to include a stopper, a spring member, and a support, which does not complicate the structure and is advantageous in terms of cost.
