Description

The present invention relates to a two-tank washing machine.

The two-tank washing machine (hereinafter referred to as two-tank washing) is equipped with a mechanism to switch the water route from the water supply means between the washing tub and the dehydration tub, and the clothes are transferred from the washing tub to the dehydration tub after the washing process. Therefore, the water supply path can be switched to the dehydration tank side to perform pre-dehydration rinsing (see Patent Document 1).

Japanese Unexamined Patent Publication No. 2016-20208

In the two-tank washing, which has traditionally followed the basic structure, it is assumed that the amount of water supplied is 30 L / min or less. However, as the washing capacity increases, the water supply time also increases, making it difficult to supply water at 30 L / min or less. When water is supplied at 30 L / min or more, the water pressure affects the switching mechanism. Water may overflow or flow into unselected tanks.

An object of the present invention is to provide a mechanism capable of switching the water supply route without being affected by the water pressure because the water supply may not be sufficiently switched between the washing tub and the dehydration tub due to the influence of the water pressure. The purpose is to provide a two-tank washing machine.

In order to solve the above problems, the two-tank washing machine of the present invention provides a washing tub for washing stored clothes, a dehydration tub formed separately from the washing tub, and water to the washing tub and the dehydration tub. A water supply unit for supplying water, a switching unit for switching the flow of water from the water supply unit to the washing tub or the dehydration tub, a water channel for supplying water from the water supply unit to the switching unit, and a cylinder provided at the tip of the water channel. It has a structure in which the length of the cylinder extends below the central portion of the switching portion.

According to the present invention, it is possible to provide a two-tank washing machine having a mechanism capable of switching a water supply route without being affected by water pressure with a simple configuration.

It is a state view which opened the dehydration tub outer lid, and closed the dehydration tub inner lid in the external perspective view of the two-tank type washing machine of this invention. It is the external perspective view of the two-tank type washing machine of this invention, and is the schematic block diagram around the switching part. It is a state sectional view of the switching part of the two-tank type washing machine of this invention. It is a state diagram which showed one Example of the cylinder body in the switching part of the two-tank type washing machine of this invention. It is a state diagram which showed the other embodiment of the cylinder in the switching part of the two-tank type washing machine of this invention.

As shown in FIGS. 1 and 2, the two-tank washing machine according to the present embodiment includes a housing 1 and a cover 5 under the housing, and a two-tank water receiving tank 4 for storing water is inside the housing 1. Is located in. The two water receiving tanks 4 are divided into a washing side and a dehydrating side. The operation panel 7 on the upper part of the housing 1 is provided with a washing timer 8 for adjusting the washing time and a dehydration timer 9 for adjusting the dehydration time.

First, a lint net 31 is provided on the washing side, and a water supply unit (such as a water supply Tsugite 41 (see FIG. 5)) for supplying tap water and a water channel 30 are provided above the washing tub 2 to provide the washing tub 2. A stirring blade 14 is installed at the bottom. Here, the stirring blade 14 is connected to the washing tub shaft 16 and rotates by using the power of the washing motor 17, to wash the clothes stored in the washing tub 2.

On the other hand, on the dehydration side, a dehydration tub 3 separate from the washing tub 2 is installed inside the housing 1, and a dehydration tub drain hole 15 is formed on the wall surface of the dehydration tub 3. Further, a dehydration tank balancer 32 is provided in the upper part of the dehydration tank 3, and a dehydration tank shaft 18 is provided in the lower part of the dehydration tank 3, and the power of the dehydration motor 22 connected to the dehydration tank shaft 18 is used. The dehydration tank 3 rotates.

Further, the lid that closes the opening of the dehydration tub 3 in the two-tank washing machine according to the present embodiment has a double lid structure. Specifically, as shown in FIGS. 1 to 5, a dehydration tub inner lid 11b is provided inside the upper cover 6 on the dehydration tub 3 side and on the front portion of the two-tank washing machine to prevent clothes from popping out. Further, it is provided with a dehydration tank outer lid 11a that covers the dehydration side clothing inlet 13 of the housing 1.

Further, the dehydration tank inner lid 11b is provided with a plurality of dehydration tank watering holes 33 (see FIG. 5), and water is supplied from the dehydration tank water supply path 28 (see FIG. 6) with the dehydration tank inner lid 11b closed. The water is showered on the clothes placed in the dehydration tank 3 through the dehydration tank watering hole 33 of the dehydration tank inner lid 11b, and the pre-rinse can be performed.

Next, a mechanism for switching the water supply to the washing tub 2 and the dehydration tub 3 will be described.

As shown in FIG. 6, a water supply tsugite 41 is inserted into the water channel 30, a switching portion 23 is arranged below the water channel 30, and a washing tub water supply path 27 and a dehydration tub water supply path 28 2 are composed of a panel box 24 and a guide lid 25. It is provided with two water supply paths, and the panel box 24 and the guide lid 25 are connected by a claw fitting 26.

Water is supplied to the washing tub 2 or the dehydration tub 3 via the water supply tsugite 41, the water channel 30, and the switching portion 23.

By tilting the switching unit 23 to the left as shown in FIG. 7, water is supplied to the washing tub 2 via the water supply tsugite 41 and the water channel 30, and the tilted switching unit 23 and the washing tub water supply path 27, and the switching unit 23 is tilted to the right. This makes it possible to supply water to the dehydration tank 3 from the dehydration water supply path 28.

However, depending on the arrangement relationship between the water channel 30 and the switching unit 23, the water supply may not be sufficiently switched between the washing tub and the dehydration tub due to the influence of water pressure, and water leakage from the upper surface of the switching unit 23 may occur. There is sex.

In the present invention, in order to solve this problem, a tubular body 43 is provided at the tip of the water channel 30.

Specifically, it will be described below with reference to FIGS. 8 and 9.

In FIG. 8, a vinyl chloride cylinder 43 is provided at the tip of the water channel 30, and the length of the cylinder 43 extends below the substantially central portion of the switching portion 23, that is, the tip of the cylinder 43. It is assumed that the portion (lower end portion) is below the central portion of the switching portion 23. By extending the tubular body 43 below the central portion of the switching portion 23 in this way, it is possible not only to prevent the water channel from being arbitrarily switched in an unintended direction due to the influence of the water pressure, but also to prevent the water pressure from being switched in an unintended direction. It is possible to prevent water leakage from the upper surface of the switching portion 23 due to the influence of.

Further, as shown in FIG. 9, the length of the tubular body 43 extends below the central portion of the switching portion 23 and extends downward from the tip portion, that is, the tip portion (lower end portion) of the cylinder body 43 has a structure. By assuming that it is below (protruding) from the tip (lower end) of the switching portion 23, water does not flow to the switching portion 23, and as in FIG. 8, the water channel is arbitrarily created due to the influence of water pressure. Not only can it be prevented from being switched in an unintended direction, but it is also possible to eliminate water leakage from the upper surface of the switching portion 23 due to the influence of water pressure.
