Description

[Detailed description of the invention] This invention relates to a so-called two-tank washing machine with a dehydrating device.

Conventionally, washing machines have been provided with insertion holes for the drain hose on both the left and right sides of the main body so that the drain hose can be pulled out from either the left or right sides of the main body depending on the installation location.

However, the left-right nature of the drain hose makes it troublesome to replace, as it requires opening the back cover of the main body, sequentially pushing the drain hose into the main body through the insertion hole, and then sequentially pulling it out from the insertion hole on the other side.

Also, due to the installation location, there is often a demand for draining water to the front of the main body.

Conventional washing machines that can be replaced with drain hoses on both the left and right sides cannot meet this demand.

As a solution to this problem, it was proposed to provide a hose insertion hole on the front of the main unit, but when the hose insertion hole on the front is not used, an unnecessary hole is left on the front, which is a real design problem. It's bad.

Furthermore, in conventional washing machines, the drain valve is installed on the girder plate at the bottom of the main body, and the washing tank and the drain valve are connected with an internal hose, so the internal hose and the drain hose between the drain valve and the hose insertion hole are connected to the drain valve. Horizontal portions are created, and the drainage path is long and complicatedly curved, which takes a long time to drain, and has the disadvantage of being easily clogged with foreign matter.

This idea allows the drain hose to be easily attached to and replaced from the front of the main unit and both the left and right sides, and the design does not create any unnecessary holes in the main unit, making it more aesthetically pleasing.Furthermore, the drainage path is better than that of conventional washing machines. The purpose is to shorten the drainage time by making it shorter.

That is, the valve box joint unit 24 includes a box body 25 that surrounds the drain port 21 and is fixed to the lower surface of the washing tank 11, a lid plate 26 that covers the bottom of the box body, and a joint 27 formed on the lid plate 26.

The box body 25 has a valve seat 28 facing the drain port 21.

Reference numeral 29 denotes a valve that is pressed toward the valve seat 28 by a spring 30, and integrally has an extensible bellows 32 surrounding the spring 30 and the valve rod 31.

The valve rod 31 is connected to a manual operation device in the control box via a Bowden cable 33, and the valve 29 can be brought into contact with and separated from the valve seat 28 by manual operation, and the drain port 21 can be opened and closed.

The joint 27 communicates with the drain port 21 through the inside of the box body 25.

A side surface of the joint 27 has a connection port 35 connected to the drain port 23 of the dewatering tank 12 via an intermediate hose 34, and also has a connection port (not shown) connected to an overflow hose.

A drain hose 36 is connected to the lower end of the joint 27.

Generally, the washing tank 11 of a washing machine is made larger than the dewatering tank 12.

In this invention, the drain port 21 provided on the rear lower surface of the washing tank near the dewatering tank is located at approximately the same distance from both left and right sides and the front surface of the washing machine main body 10.

Therefore, the joint 27 is closer to the dewatering tank 12 than the drain port 21, and is located at a more accurate equidistant distance from both left and right sides of the main body 10 than the drain port 21.

The drain hose 36 is pulled out from the bottom opening 15 of the main body 10 to the lower part of the main body.

This hose hook 44 is located at almost the same height as the aforementioned hose hook 43, and its both ends are attached to the hook holes 3 on the front side.
9 C, and when the drain hose 36 is pulled out from the left or right side of the front surface, it can be removably hooked to the left or right end of the drain hose 36.

In the above embodiment, the hose hook has the tools permanently installed on the front surface and both left and right sides of the main body, but the hose hook may be attached to each side so that the tools can be attached interchangeably.

In the embodiment shown in FIGS. 6 and 7, reference numeral 45 is the only hose hook provided in the washing machine, and the side surface is almost inverted, and the upper horizontal side of the inverted shape allows the drain hose 36 to be attached and detached. He is admonishing from a pair of arms that embrace him.

The hose hook 45 has a protrusion 4 having an enlarged head on the back side.
6, and is removably attached by inserting the protrusion 46 into the 7-shaped hole 47 drilled on the side of the main body 10 from the upper enlarged hole part and sliding it downward, and can be attached to the left or right side. The attachment can be changed.

In addition, the hose hook 45 has a hooking recess 48 on the front side of the vertical side of the upside-down shape, and the dimension from the bottom of the recess 48 to the tip of the protrusion 46 is approximately the same as the distance between the towel hook 49 and the main body 10. are created equal.

Therefore, the hose hook is the tool 45, and the towel rack is the tool 49 and the main body 10.
As shown in FIG. 7, by press-fitting between
9 and the main body 10 in a removable manner.

Note that the 7-shaped hole 47 and the towel rack are located at approximately the same height as the tool 49.

This idea consists of the structure described above.

The valve box joint unit is installed directly at the drain port of the washing tank, and the drain hose connected to the valve box joint unit is pulled out from the bottom of the main unit, so the internal hose of conventional washing machines is omitted and the drainage path is shortened. As the drainage rate decreases, the waste water flows directly downward from the drain outlet and is guided to the drain hose, which reduces the horizontal portion of the drainage path, increases the drainage speed, and reduces drain time, making it more efficient. This will help you with your cleaning work.

In addition, a drain port is provided on the rear lower surface of the washing tank near the dewatering tank, and a two-knit valve box joint is installed directly at the drain port, so the fixed end of the drain hose can be placed almost evenly in front of the main body and on both left and right sides. Even if the drain hose is pulled out from either the front or both the left and right sides, there will be no significant difference in length, and the drain hose can be easily handled from either side of the main body, and the drain hose can be easily Easy to work with.

Furthermore, the legs are made higher than the outside diameter of the drain hose, and the drain hose is brought out from the opening at the bottom of the main unit and pulled outward from between the legs, which increases the drainage speed as mentioned above and also changes the direction of the drain hose. The work does not require much effort as in the past, and the hose can be easily pulled out in any direction, which is extremely convenient when installing or changing the installation location of the washing machine.

In addition, since there is no need for an insertion hole for the drain hose as in the past, there is no need for an ugly design like other insertion holes that become useless once installed, and it is possible to create a good-looking appearance. The high legs prevent water from splashing onto the bottom of the main unit, which prevents it from rusting and maintains its beautiful appearance for a long time.
