Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a fully automatic one-tub dehydrating washing machine for home use.

Conventional configuration and its problems Recently, a method has been adopted in which both a washing machine and a dryer are installed and all processes from washing to drying are done in the same place, which greatly saves the user's effort.
Additionally, in order to minimize the area occupied by washing machines and dryers in homes, it has become common to install dryers on top of washing machines via a stand. Many dehumidifying dryers are used, which are equipped with a heat exchanger that cools and dehumidifies the hot, humid air discharged from the dryer, and do not discharge hot, humid air indoors.

However, as mentioned above, when a dryer is installed in the same place as a washing machine, two drainage routes are required: the washing machine's drainage hose and the dryer's dehumidifying water drainage pipe, so it is difficult to install the dryer indoors. Wastewater treatment becomes difficult.

Therefore, in the past, a method has been adopted in which the dehumidified water is drained into the washing tank of the washing machine using the configuration described below, and the water drainage path is reduced to one drain hose of the washing machine. .

Figure 1 shows the structure of a conventional washing machine and dryer, in which 1 is a washing and dehydrating tank, 2 is a rotary blade rotatably installed at the bottom of the washing and dehydrating tank, and 3 is a drive for the rotary blade 2, etc. This is the drive unit that causes the Reference numeral 4 denotes a main body, and the main body 4 has a top plate on the top, and an operation plate 6 is provided on the front side of the top plate 5.

A control board 7 for controlling the drive unit 3 of the washing machine and the like is fixed to a top back plate 8 on the inner rear side of the top plate 5, and this top plate back plate 8 is connected to the top plate. It is screwed to the lower part of 5. 9 is a support rod.
Reference numeral 10 denotes a dehumidifying dryer, and its lower part has a drain pipe 11 for discharging dehumidified water to the outside of the machine. It is inserted into the socket 12. or,
A drainage channel 13 is provided in a portion of the top back plate 8 corresponding to the lower part of the socket 12, and the dehumidified water flowing out from the drain pipe 11 inserted into the socket 12 is
The washing tank 14 falls onto this drainage channel 13, passes through the drainage channel 13, and is supported by the support rod 9 in a vibration-proof manner.
It is structured so that it falls inside. 15 is dryer 1
1 is a washing tank cover.

According to the above configuration, since water is discharged from the drain pipe 11 of the dehumidifying dryer 10, a small amount of hot and humid air is also discharged, so a large amount of water condenses on the inside of the top plate 5, the control plate 7, etc. However, there are disadvantages in that the life of each electrical component in the control board 7 is significantly shortened, malfunctions occur, and condensed water falls onto the floor.

In order to eliminate the above-mentioned inconvenience, a water reservoir is provided in the middle of the drain pipe 11 to discharge water to the outside of the machine, while preventing hot and humid air from leaving the machine. structure was proposed.

However, this structure causes the following problems.

That is, when a single-tank fully automatic washing machine and a dehumidifying dryer are operated at the same time, if water dehumidified during dehydration operation drips onto the washing tank cover through the drainage channel 13,
If the clothes in the washing/spinner tank are unbalanced,
The vertical vibration of the saucer part of the washing tub cover becomes large, and the water that drips onto the saucer part of the washing tub cover is splashed by the vertical vibration, and the wind generated by the rotation of the washing and dehydrating tub causes the water to be blown away by the saucer part of the washing tub cover. There was a problem with it splashing outside and making the floor wet.

Purpose of the invention This invention prevents the water dripping from the dehumidifying dryer that is running at the same time as the dehydrating washing machine from splashing due to the vertical vibration of the washing tank cover, and The purpose is also to prevent water from spilling.

Structure of the Invention The present invention has a structure that includes a laundry receiver that accommodates a washing tub and a dewatering tank, and a laundry receiver cover that is attached to the upper opening of the laundry receiver, and on the upper surface of the outer periphery of the laundry receiver cover. A saucer portion surrounded by wall-like ribs and a drainage hole for draining water accumulated in the saucer portion were provided, and a plurality of pins or ribs were erected on the saucer portion.

As a result, the waste water from the dryer drips onto the tray provided on the washing tank cover, and the water collected there is drained from the drain hole.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 2 is a partial perspective view of the laundry receiving tank cover 16, in which a receiving tray portion 17 whose outer periphery is surrounded by wall-like ribs is provided in the portion of the upper surface where dehumidified water drips.
The dehumidified water dripping from the drain channel 13 is made to drip from the drain hole 17a to the overflow pipe portion of the washing tank as shown in FIG. 3. Note that the saucer portion has an inclined surface so that water can be drained smoothly into the drain hole 17a.

When dehumidified water drips into the saucer part 17 during dehydration operation, a structure for preventing the dehumidified water from splashing up and down due to the vertical vibration of the washing tub 14 and the washing tub cover 16 is shown in FIGS. 4 and 5. A plurality of pins 18 or ribs 18a as shown in FIG. In this way, the dehumidified water will adhere to the pins 18 or the ribs 18a, so that the dehumidified water will not splash up and down even due to vibrations. Furthermore, by erecting a plurality of pins 18 or ribs 18a, scattering of dehumidified water caused by wind during the dehydration operation can be reduced.

If the height of the pin 18 or the rib 18a is set lower than the wall-like rib on the outer periphery of the saucer portion 17, the wind generated by the rotation direction of the washing/dehydrating tub (in the direction of the arrow in Fig. 2) will cause the saucer portion to 17, it is possible to prevent the dehumidified water from scattering.

Effects of the invention According to the invention, by erecting a plurality of pins or ribs on the tray part, even when the washing tank cover vibrates up and down, it can be prevented from jumping up and down, and the dehumidified water can be prevented from reaching the floor surface. It has great practical effects such as being able to prevent dripping.
