Description

TECHNICAL FIELD The present invention relates to a washing machine having a function of discharging dehumidified water of a dehumidifying / drying machine into a washing machine.

Conventional configuration and its problems Recently, both a washing machine and a dryer are installed, and the steps from washing to drying are performed in the same place, so that the user's time and effort can be greatly saved. . In order to make the area occupied by the washing machine and dryer in the house as small as possible, it has become common to install the dryer on the upper part of the washing machine through a stand. A dehumidifying dryer having a heat exchanger that cools and dehumidifies the hot and humid air discharged from the machine and has a structure that does not discharge the hot and humid air has been widely used indoors.

In this dehumidifying dryer, the air that has been dehumidified by removing moisture from the material to be dried is cooled by a heat exchanger to dehumidify it as water, and this dehumidified water is discharged to the outside through a discharge pipe or the like.

However, as described above, when the dryer is installed at the same place as the washing machine, two drainage paths of the drainage hose of the washing machine and the dehumidified water discharge pipe of the dryer are required,
It was difficult to dispose of it indoors.

Therefore, conventionally, a method has been adopted in which the dehumidified water is drained into the laundry receiving tub of the washing machine and the drainage path of the water is set to one drain hose of the washing machine with the configuration as described below. .

FIG. 1 shows the structure of a conventional washing machine and dryer, 1 is a washing tub, 2 is a rotary wing rotatably installed on the inner bottom of the washing tub, 3 is a drive unit for driving the rotary wing 2 and the like, A main body 4 has a top plate 5 on the top of the main body 4, and an operation plate 6 is provided on the front surface of the top plate 5.

A control plate 7 and the like for controlling the drive unit 3 of the washing machine and the like are fixedly provided to the top plate back plate 8 inside the rear part of the top plate 5,
The top plate back plate 8 is screwed to the lower portion of the top plate 5. Reference numeral 9 is a supporting rod for supporting a laundry receiving tank described later.

Dehumidifying / drying machine 10 has a drain pipe 11 for discharging dehumidified water to the outside of the dryer.
1 is inserted into a drainage port 12 provided on the top surface of the top plate 5 above the main body 4. Further, a discharge passage 13 is provided in a portion of the top plate back plate 8 corresponding to a lower portion of the receiving opening 12, and the dehumidified water flowing out from the drainage pipe 11 inserted into the receiving opening 12 is discharged through the discharging passage 13. The structure is such that it drops upward, passes through the drainage channel 13, and drops into the laundry receiving tub 14 that is vibration-isolated and supported by the support rod. A unit stand 15 is supported by the dehumidifying / drying machine 10.

According to the above configuration, the drainage pipe 11 of the dehumidifying dryer 10
Since a little hot and humid air is released along with the discharge of water, a large amount of water is condensed on the inside of the top plate 5 and the control plate 7 and the life of each electric component in the control plate 7 is significantly shortened. However, there are inconveniences such as causing malfunctions and further causing dew condensation water to fall onto the floor surface.

As a solution to this drawback, the following configuration has been adopted. In this structure, a drainage pipe for guiding the dehumidified water generated by the dehumidifying / drying machine to the outside of the machine is provided. At the end of this drainage pipe, the lower end side has a bent portion having a substantially U-shape,
The end opening communicates with the upper end opening side of the drainage base member which is located at substantially the same height as or slightly higher than the substantially U-shaped part on the inner surface of the bent portion, and is connected to the upper part of the washing machine body. The provided top plate is provided with a receiving port into which the drainage mouthpiece member is freely inserted and removed, and in the washing machine body and the topboard, the dehumidified water discharged from the drainage mouthpiece member is stored in the washing machine. It is configured to be drained through a drainage path, and by forming a water reservoir portion in the substantially U-shaped portion of the drainage mouthpiece member, only hot and humid air is leaked, and only moisture is drained. It was a thing.

FIG. 2 shows an example of this type, which is a drainage pipe 11 of a dehumidifying dryer.
A drainage base member 17 is detachably inserted at the tip of the. The drainage mouthpiece member 17 has a tubular portion 1 having an upper portion having a diameter such that the drainage pipe 11 can be inserted therein.
7a, and a bent portion 17 having a substantially U shape in the lower portion.
b is integrally formed, and a water reservoir 18 is formed inside the bent portion 17b. The end opening 17c is the bent portion 1
It is located at the same height position as the substantially U-shaped portion 17d on the upper portion of the inner surface of 7b or slightly above it. Slightly above the fitting portion of the drainage base member 17 with the receiving port 17,
It has a collar portion 17e for fixing the position in the vertical direction. Further, the end opening 17c has a cut surface shape inclined downward toward the substantially U-shaped portion 17d, and the bent portion 1
A pin-shaped portion 17f protruding downward is provided at the lowermost end of 7b.

As shown in FIG. 2, the drainage mouthpiece member 17 formed in this way is inserted into the receiving opening 12 of the top plate 5, and below that, the water distribution passage integrally formed with the topboard back plate 8. 13 is provided,
The drainage channel 13 communicates with the upper portion of the laundry receiving tank.

In such a structure, the dehumidified water from the dehumidifying / drying machine passes through the drainage pipe 11 and forms a water pool in the water reservoir 18 inside the bent portion 17b of the drainage mouthpiece member 17,
Only water is drained from the mouthpiece member 17 through the end opening 17c.
It flows out. The end opening 17 of the discharge mouthpiece member 17
Since c has a cut surface shape that is inclined downward toward the substantially U-shaped portion 17d, the dehumidified water flows out from the central portion of the bent portion 17b to the lower end side and drops along the pin-shaped portion 17f. .

In the conventional example shown in FIG. 2, the problem in the case shown in FIG. 1 is solved, but the following drawbacks are newly generated.

The drainage mouthpiece member 17 has a relatively complicated shape having a substantially U-shape like the cross-sectional shape shown in FIG. 2, and it is desirable to form it from a synthetic resin material in terms of rust prevention. It takes longer than usual molding method to perform molding with this shape, and it becomes expensive in terms of cost. Further, in consideration of the case where this type of base member 17 is not used, since the receiving port 12 of the top plate 5 is opened, some kind of cap-shaped cover is required and extra parts are required.

Further, when the user installs a dehumidifying dryer, he / she forgets to use the mouthpiece member 17, and there is a risk of misuse by directly inserting the drainage pipe 11 into the receptacle 12.

An object of the present invention is to solve the above-mentioned drawbacks of the conventional example and to provide a washing machine capable of draining the dehumidifying / drying machine without anxiety.

According to the present invention, the top plate back plate is fixed to the top plate into which a drainage pipe for draining dehumidified water is inserted, so that the liquefaction chamber provided on the top plate side and the dehumidified water on the top plate back plate side are collected. A part of the wall of the recess forms a passage having a trap structure, and this passage is connected to an outflow passage having an outlet connected to the washing tub,
The dehumidified water is drained through the washing tank.

Description of Embodiment An embodiment of the present invention will be described below with reference to FIG.
The related configuration of the dehumidifying / drying machine and the washing machine is the same as that of the conventional example, and therefore the description thereof will be omitted, and the difference will be mainly described.

The washing machine main body 20 is equipped with a washing tub 22 having a balancer 21 therein and a washing tub 23 in which the washing tub 22 is installed. Similar to the conventional example shown in FIG. 1, the laundry receiving tub 23 has a drain hose connected to the bottom thereof, and a receiving plate 24 having a drain outlet 24a provided on the upper portion thereof. A drain pipe 2 for draining dehumidified water from the dehumidifying / drying machine is provided on the top surface of the top plate 25 provided on the upper portion of the washing machine body 20.
An opening 27 into which 6 is inserted is provided, and an outer peripheral portion of the opening 27 is integrally provided with a substantially tubular guide tube 28 that hangs downward in the top plate 25.

A control component 29 is provided on the inner and lower surfaces of the top plate 25, and a top plate back plate 30 is fixed below the top plate 25 so as to cover the control component 29.

At the lower end of the guide cylinder 28, a liquefaction chamber 31 is provided which is composed of a concave portion that is open downward and is closed upward. In this embodiment, the outflow tube 32 is formed by narrowing the lower end of the guide tube 28.
The liquefaction chamber 31 is formed by providing the hanging wall 33 on the side part of the.

In addition, the top plate back plate 30 is provided with a substantially cylindrical recess 34 that opens upward and collects dehumidified water, and an outflow passage 36 that has an outlet 35 that communicates with the laundry receiving tub 23. . The wall of the recess 34 on the side of the outflow passage 36 is lower than the wall of the other side so that the dehumidifying water overflowing from the recess 34 always flows to the side of the outflow passage 36. Further, the outflow port 35 faces the receiving plate 24, and the outflow port 35
The dehumidified water that flows out further flows into the washing receiving tub 23 through the drainage port 24 a of the receiving plate 24.

Then, by fixing the top plate back plate 30 to the top plate 25, a part of the wall of the recess 34 of the liquefaction chamber 31 (that is, the wall 3).
7) Trapped passage 3 leading to the outflow passage by
8 is automatically assembled and formed. In the above configuration, the high-temperature dehumidifying water from the dehumidifying / drying machine temporarily collects in the recess 34 through the drainage pipe 26.

Before the dehumidified water accumulates to the lower end of the outflow pipe 32, that is, to the lower end of the guide pipe 28, most of the vapor generated from the dehumidified water is dewed in the liquefaction chamber 31 while passing through the passage 38 having the trap structure. When the dehumidified water collects up to the lower end of the guide cylinder 28, the steam is liquefied when passing through the accumulated dehumidified water and flows over the wall 37 to the washing receiving tub 23 as shown in the drawing.

EFFECTS OF THE INVENTION As described above, according to the present invention, the liquefaction chamber provided on the top plate side by fixing the top plate back plate to the top plate and the wall of the recess on the top plate back plate side for storing dehumidified water are provided. A part of a passage with a trap structure was formed, and the dehumidifying water was drained through the washing tub by connecting this passage to an outflow passage having an outlet connected to the washing tub. There is no need for a drainage base member, and there is no risk of forgetting to install it. Also, since the top plate and the top plate back plate can be integrally formed, the number of parts can be reduced, and the top plate back plate is fixed to the top plate automatically for assembly. It is also excellent in sex.
