Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to an electric washing machine.

[0002]

2. Description of the Related Art In an electric washing machine, a washing and dewatering tub is rotatably installed in an outer tub suspended from an outer frame, and a stirring blade is rotatably installed at the bottom of the washing and dewatering tub. Water is supplied from the water supply solenoid valve built in the back panel box formed between the upper cover attached to the upper end portion of the outer frame and the back panel from the top of the washing and spin-drying tub through the water injection section into the washing and spin-drying tub. It is going to be poured like a shower.

[0003] The water injection section is provided with a detergent introduction section and a softener introduction section for automatically pouring a detergent and a softener together with water supply.

[0004]

At the start of washing, it is necessary to ensure that the detergent can be poured in at the start of washing, and in the rinsing step, water droplets should be formed as finely as possible in the rinsing step and the shower should be spread vigorously over a wide area. It is desirable to be able to inject water. In particular, in the case of washing using a powdered detergent, it is necessary to surely pour the detergent so that the detergent does not remain in the detergent input portion.

[0005] However, if the feed water controlled by one feed water solenoid valve is configured to be distributed to the water for pouring the detergent and the water for shower water injection, the flow rate of each water is reduced, so that the water source (for example, water supply) There is a problem that when the water pressure is lowered, the detergent is left behind and the momentum of shower water is reduced. In particular, in an electric washing machine having a water softening water supply device that removes ionic components harmful to washing contained in tap water with an ion exchange resin and softens the water, the above problem is caused by a large water pressure loss caused by the water softening water supply device. Becomes noticeable.

By installing a dedicated water supply solenoid valve for introducing the detergent, it is possible to secure a sufficient flow rate of the water for surely flowing the detergent, but the number of components increases and the structure becomes complicated. There's a problem.

[0007] Further, since there are two types of detergents, powder detergents and liquid detergents, it is desirable that both detergents can be used easily.

[0008] One object of the present invention is to make it possible to effectively use the water supplied from one water supply solenoid valve to reliably feed the detergent and inject the shower water.

It is another object of the present invention to enable shower water to be injected over a relatively wide area.

It is still another object of the present invention to enable sufficient shower water injection even when water is supplied from a low water pressure water source.

Yet another object of the present invention is to make it easier to use powder detergents and liquid detergents.

[0012]

Reference numeral 61 protrudes so as to raise the siphon pipe 262 in the middle thereof. Then, a siphon is formed by fitting a siphon cap 263 as shown in FIGS. 17 and 18 into the siphon pipe 262, and the liquid contained in the softener container 261 is supplied by supplying water to the softener container 261. By diluting the softener to increase the water level, the liquid softener flows out of the siphon pipe 262 by a siphon action. The siphon cap 263 also displays the softener storage level in which the flange 263a is formed.

In this electric washing machine, when washing is performed by automatically inputting powder detergent by timer reservation, as shown in FIG. 2, the main body 200 of the water injection section 20 is pulled out into the clothes input port 9a, and FIG. As shown in FIG. 21, the powder detergent input tray 249 is placed on the mounting frame 241 with the dish detergent 249 facing upward. The installation of the powder detergent introduction plate 249 is performed by engaging the shower water supply frame portion 252 so as to be fitted into the shower water supply chamber 221a of the shower box side frame 221 so that the bottom surface of the powder detergent placement portion 253 is supported by the front support plate 244. And is placed on the rear support plate 247. In this installation state, the powder detergent mounting portion 253 is inclined so that the rear side is lowered, so that the powder detergent easily flows down. Then, the powder detergent 301 is placed on the powder detergent placement section 253.

In the softener container 261, a siphon cap 263 is fitted to a siphon pipe 262, and a liquid softener is placed in the softener container 261 as necessary.

Thus, the main body 200 containing the powder detergent 301 and the liquid softener is pushed into the upper cover 9 to complete the preparation for washing.

When the washing is started, the main controller 1
7 first executes the water supply by opening the washing water supply electromagnetic valve. In this water supply, tap water supplied from a water tap connection port 19 is softened through a water softening water supply device 21 and then injected into the washing right dewatering tub 2 (outer tub 5) via a water injection unit 20.
At this time, in the water injection unit 20, as shown in FIG.
The shower water supply frame 252 side and the powder detergent
Divide the water to the 3 side. Then, the washing water that has flowed to the shower water supply frame 252 side flows into the shower water supply chamber 221a, falls down in a shower shape from the water injection hole 225a toward the washing and dewatering tub 2, and flows to the powder detergent mounting part 253 side. The separated washing water flushes the powder detergent 301 placed on the powder detergent mounting portion 253 along the slope of the powder detergent mounting portion 253 to wash from the rear end of the powder detergent mounting portion 253. Pour into the dewatering tank 2.

In this automatic powder detergent introduction, the powder detergent mounting portion 253 is located at a lower position with respect to the water receiving portion 250 and is inclined. Thus, the amount of water that flows into the shower water injection chamber 221a and falls down like a shower from the water injection hole 225a can be relatively increased.

In the configuration using the bottom plate 224 as shown in FIG. 8, when the water pressure of the tap water decreases and the amount of water flowing into the shower water supply chamber 221a is small, the water flowing into the shower water supply chamber 221a is removed from the bottom plate part. Since it gathers in the lower central portion 225b and intensively injects shower water from the water injection hole 225a in this portion, it is possible to suppress the shower injection mode from being disturbed.

When the water level in the washing and dewatering tub 2 reaches a predetermined value in this way, the main controller 17 closes the washing water supply electromagnetic valve and instructs the auxiliary controller 29 to rotate the stirring blade 4 forward or backward. By controlling the electric driving device 6 so that

Next, in the rinsing step, the main controller 17
Opens the drainage solenoid valve 23 to open the outer tub 5 (washing and dewatering tub 2)
The dirty washing water in the inside is drained, and after the drain electromagnetic valve 23 is closed, the water supply electromagnetic valve is opened to supply water into the washing / dewatering tub 2. The water supply at this time is divided in the same manner as the water supply in the washing step, and a part of the water flows into the shower water supply chamber 221a and falls down from the water supply hole 225a toward the washing and dewatering tub 2 in a shower shape. Since the shower water injection amount can be relatively large as described above, the rinsing efficiency can be improved. And the main control device 17 is the auxiliary control device 2
9, the electric driving device 6 is controlled so as to rotate the stirring blade 4 in the normal and reverse directions, and then the drain / electromagnetic valve 23 is opened to rotate the washing and dewatering tub 2 while draining the rinsing water to lightly dehydrate. Thus, control is performed to increase the drainage efficiency of the dirty rinse water.

Such rinsing is repeated as many times as necessary,
At the time of water supply in the last rinsing, the softener supply water supply electromagnetic valve is opened to supply water to the softener container 261 to raise the level of the liquid softener contained in the softener container 261, and the siphon by the siphon pipe 262 and the siphon cap 263. The action causes the liquid softener to flow out of the siphon pipe 262 into the washing and dewatering tub 2.

Then, when the dehydration process starts, the main controller 1
7, the drainage electromagnetic valve 23 is opened to drain the rinsing water in the outer tub 5 (washing and dewatering tub 2), and then the washing and dewatering tub 2 is rotated at a high speed by instructing the auxiliary control device 29 to perform dehydration. The electric drive device 6 is controlled as described above.

Further, the washing and dewatering tub 2 is manually washed with the powder detergent.
When the laundry is put directly into and washed, as shown in FIG.

The installation of the powder detergent introduction plate 249 is performed by engaging the shower water supply frame portion 252 so as to be fitted into the shower water supply chamber 221 a of the shower box side frame 221, and supporting the rear end of the powder detergent mounting portion 253 with the rear support projection. 245, 246. In this installation state, the shower water supply frame 252
Is at a low position, and the powder detergent mounting portion 253 is inclined such that the rear side is higher.

In the softener container 261, a siphon cap 263 is fitted to a siphon pipe 262, and a liquid softener is placed in the softener container 261 as necessary.

Thereafter, the main body 200 is pushed into the upper cover 9 to complete the preparation for washing.

When the washing is started, the main controller 1
7 first executes the water supply by opening the washing water supply electromagnetic valve. In this water supply, tap water supplied from a water tap connection port 19 is softened through a water softening water supply device 21 and then injected into the washing and dewatering tub 2 (outer tub 5) via a water injection unit 20.
At this time, in the water injection unit 20, the powder detergent input plate 249 is
As shown in FIGS. 22 to 24, all of the washing water supplied from the water softening / water supply device 21 acts to flow into the shower water supply chamber 221a. Therefore, the amount of water that falls down like a shower from the water injection hole 225a can be significantly increased.

Then, washing similar to the washing step, rinsing step and dehydrating step described above is performed, but the amount of water injected into the shower can be significantly increased. Water can be absorbed, and in the rinsing step, the disappearance of bubbles can be accelerated, and the rinsing efficiency can be greatly improved.

When a liquid detergent is automatically supplied by a timer reservation and washing is performed, as shown in FIG. 2, the main body 200 of the water injection unit 20 is pulled out into the clothes input port 9a, and the powder detergent mounting plate 249 is removed. As shown in FIGS. 25 to 27, siphon cap 257 is attached to siphon pipe 257.

In the softener container 261, a siphon cap 263 is fitted to a siphon pipe 262, and a liquid softener is placed in the softener container 261 as necessary.

The main body 200 containing the liquid detergent and the liquid softener is pushed into the upper cover 9 in this manner, and the preparation for washing is completed.

When the washing is started, the main controller 1
7 first executes the water supply by opening the washing water supply electromagnetic valve. In this water supply, tap water supplied from a water tap connection port 19 is softened through a water softening water supply device 21 and then injected into the washing right dewatering tub 2 (outer tub 5) via a water injection unit 20.
At this time, in the water injection section 20, as shown in FIGS. 21 to 24, the washing water supplied from the water softening water supply device 21 is supplied to the shower water supply frame 256 side in the concave portion 255a of the front wall of the liquid detergent storage container 255 and the water. Water is separated inside the liquid detergent container 255. Then, the washing water that has flowed to the shower water supply frame portion 256 side flows into the shower pouring chamber 221a, and falls down like a shower from the water pouring hole 225a toward the washing and dewatering tub 2 to be distributed inside the liquid detergent container 255. The drained washing water dilutes the liquid detergent contained in the liquid detergent container 255 to raise the water level, and the siphon pipe 2
From 57, it flows out to the washing and dewatering tub 2.

In this automatic liquid detergent introduction, the amount of water supplied into the liquid detergent container 255 should be relatively small because it is sufficient that the water level exceeds the outflow start water level of the siphon pipe 257 during this water supply. Therefore, it is poured into the shower water supply chamber 221a and
The amount of water that falls from 5a like a shower can be made relatively large.

When the water level in the washing and dewatering tub 2 reaches a predetermined value, the main controller 17 sequentially performs the washing step, the rinsing step, and the dehydrating step in the same manner as in the washing using the powder detergent. To run.
