Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and a device for absorbing water from a water source other than a water pipe, such as bath water, in an automatic water supply type washing machine having a function of directly supplying water from the water pipe.
It is used when the bath water is used for washing in an automatic household washing machine.

[0002]

2. Description of the Related Art Conventionally, the following method has been used to supply washing water to a fully automatic washing machine. First, it was performed by directly connecting to a washing machine from a tap of a water supply via a rubber hose or the like. Secondly, a small water suction pump was used at the expense of the function of the automatic washing machine. Thirdly, the bath water suction pump built into the automatic washing machine was used.

Before the advent of automatic washing machines, housewives often used bath water as washing water. in this case,
Unless the automatic washing machine has a built-in water absorption pump, a simple water absorption pump was used to manually start and stop the pump when absorbing and draining water. Or, the timer set the operating time of the water absorption pump. And the setting of this operating time relied on experience.

Since the automatic washing machine is not provided with a dedicated pipe for guiding the water drawn from the water suction pump to the washing tub, the end of the hose is locked with a clip. This is inconvenient when using the bath water even for rinsing. Because, if the lid of the washing tub is open during dehydration, dehydration will not start, so it was necessary to remove the hose one by one.

[0005]

Recently, the construction of dams has become difficult due to increasing environmental problems, and the development of water resources is becoming difficult. Therefore, the need to save water in order to effectively use water resources has been exclaimed. There is. In addition, automatic washing machine (water supply,
In a washing machine that automatically performs drainage and dehydration under microcomputer control), tap water is directly injected, so especially in winter, the temperature of tap water is low, and it often deviates from the optimum temperature of laundry soap. The detergent becomes difficult to dissolve.

With the spread of automatic washing machines, it seems that the use of bath water as washing water has decreased. This is because the housewives were opened by manually opening and closing the faucet with an automatic washing machine, but they were reluctant to use bath water that would lose its convenience. To be

In view of this, the present invention aims to increase the use of bath water as washing water, with the object of saving water and supplying water of a temperature suitable for laundry soap to an automatic washing machine.
It is an object of the present invention to improve the operability of a water absorption pump without significantly impairing the convenience of an automatic washing machine.

[0008]

As one would experience when using an automatic washing machine, the faucet of the tap is opened and water is supplied to the washing tub. When a predetermined amount of water is accumulated in the washing tub, the solenoid valve is closed. As a result, the water supply hose expands with the pin due to the water pressure.

[0021]

[Embodiment] Although not mentioned in advance, water supply in the specification is a method of supplying wash water by directly connecting to a water supply which is originally provided in an automatic washing machine, and water absorption is washing water obtained by pumping water by a water absorption pump. Is the method of supply.

FIG. 1 shows an embodiment of the method and the apparatus according to claims 1 to 3. A member 1 having a through-hole for passing tap water is provided with a pressure sensor for measuring the pressure in the water absorption pipe. As a pressure sensor,
A variety of commercially available pressure sensors can be selected.

The tap water from the tap is directly supplied to the automatic washing machine via the water supply hose 2. In this embodiment, the member 1 is connected between the water supply hose 2 and the water supply port 3 of the washing machine. This embodiment, which is connected to the water inlet 3 of the washing machine, is optimal. It is the cheapest and simplest to manufacture the member 1 in which the female screw engaging with the male screw portion of the water supply port 3 of the washing machine is provided on one side surface and the male screw is provided so that the water supply hose can be connected to the surface facing this surface. .

The fluctuation signal of the pressure measured by the pressure sensor is transmitted to the water suction pump control means 4 and is subjected to predetermined signal processing such as signal amplification to start and stop the water suction pump 5, so that the predetermined pressure level is obtained. Make a comparison. Then, the water absorption pump control means operates so as to stop the water absorption when the pressure exceeds the predetermined pressure, and controls the water absorption pump so as to absorb the water when the pressure is lower than the predetermined pressure.

The temporal fluctuation of the pressure in the water supply hose 2 measured by the pressure sensor follows the change shown in FIG. 2 with the start of water absorption from the water absorption hose 6 to the washing machine. At this time, the water supply with the water supply hose is performed with the faucet of the water tap squeezed more than usual, so the washing machine detects that the water is full and closes the solenoid valve for the water supply pipe to stop the water supply and then gradually Water pressure increases (due to tap water gradually accumulating in the water supply hose). Then, the water suction pump 5 is started and stopped with reference to a predetermined pressure between the maximum pressure and the minimum pressure.

FIG. 2 shows that there is a time lag between when the washing machine is full and when the water suction pump is stopped. This is because the flow rate of water to be supplied per unit time is arbitrarily determined by the degree of tapping of the tap, so the slope of the graph changes according to the amount of water supply per unit time.

Further, due to the difference between when the full water is sensed and when the water supply pump is stopped, extra water in the bath is absorbed in the washing machine, but since the time of the difference does not become so long, a large amount is taken as a whole. Unnecessary bath water is never supplied to the washing machine.

A second embodiment is shown in FIGS. Here, unlike the first embodiment in which the pressure in the water supply hose 2 is measured, the presence or absence of the flow of water in the water supply hose is detected by a water flow detection sensor. Then, the water suction pump is operated while the water flow in the water supply hose is detected, and the water suction pump is controlled by the water suction pump control means so as to stop the water suction pump while the water flow is not detected. .

FIG. 4 shows the relationship of the water flow over time. Again, the slope of the graph will change depending on how much the tap for the water supply is opened. In actual use, the tap is opened to increase the flow rate of tap water per unit time until the water flow detection sensor can detect the water flow.

By the way, when there is a feeling of resistance to using the bath water until the final rinse of the laundry, the washing machine main body is set so as not to perform the final rinse. After the washing set by the washing machine is completed, the water absorption system should not be activated (switch off), the faucet of the water supply should be fully opened, and only the finishing rinse should be set on the washing machine body.

If the number of washing and rinsing is known, it is possible to prevent the water absorbing pump from operating more than the number of washing and rinsing by adding a counter to the water absorbing pump control means. is there.

It is desirable to provide the water suction pump with a bath water level detection sensor. Since the amount of water remaining in the bath is not constant, it may happen that one wash is not enough.
If all the water in the bath is pumped out by the water absorption pump, the water absorption pump will start spinning. In order to prevent the suction pump from running idle, it must be detected that the bath water has run out. When the water level sensor attached to the water absorption pump detects that the bath water is exhausted, it is desirable to make an alarm sound such as a buzzer or stop the water absorption motor.

In practice, when the amount of bath water decreases and the rotor blades of the water absorption pump come to the surface of the water, the draining noise becomes high and the rotating noise of the motor becomes audible. Is running out of water. "
I can know. Therefore, the need for a special water level sensor may not be so high. In some cases, instead of attaching a water level sensor, it is desirable to increase the rotation noise of the motor or to devise the rotary blades of the water absorption pump to increase the drain noise.

In the first and second embodiments, the bath water is supplied as rinsing water even in the rinsing stage, and the rinsing water is not sufficiently supplied in the case where the number of times of operation of the water absorption pump is set. Because it is not possible (the amount of water supply per unit time is small because the faucet is squeezed), it is necessary for housewives to fully open the faucet. A third embodiment in which bath water is not used in finishing rinsing and only tap water is supplied and a flow dividing means and a solenoid valve are used will be described.

A third embodiment will be described with reference to FIG. 5. A diversion pipe 15 having first and second water channels for diverting water from a water source such as a tap water into two systems is provided, and the first water channel is a pipe. The diameter per unit time is reduced by reducing the diameter (corresponding to narrowing the faucet in the first and second embodiments), while the solenoid valve 13 is interposed in the second water channel. The solenoid valve closes the second water channel within a predetermined number of times of starting the water absorption pump, and keeps the second water channel open after the predetermined number of times of operation, and counts the number of times of starting the water absorption pump. It has a water supply control function to which is added.

The electromagnetic valve 13 is kept closed until the number of times of operation of the water suction pump reaches the set number, and tap water is supplied little by little through the first water channel (the tap of the water supply in the first and second embodiments is squeezed, Equivalent to reducing tap water supplied per unit time).

Since the number of times of starting the water absorption pump can be set,
When the water suction pump is operating, tap water is constantly supplied from the first water channel. On the other hand, during this period, tap water is not supplied because the electromagnetic valve is closed in the second water channel.

After the number of times of starting the water absorption pump reaches the set number of times, the water absorption pump is not started. On the other hand, the solenoid valve 13 of the second water passage is opened by the solenoid valve driving means 14 so that tap water is supplied through the first and second water passages. The second water channel flows water from a water source that did not flow to the first water channel.

In the third embodiment, when the bath water is not sufficiently absorbed on the basis of the output signal of the sensor for detecting the water level of the bath water and the water flow of the water absorption pipe, the water absorption pump is operated as described above. It is not activated (the water absorption operation of the water absorption pump is stopped in the middle of water absorption), while the electromagnetic valve of the second water channel is opened to supply tap water through the first and second water channels.

By the way, generally, in an automatic washing machine, water is supplied from a water source such as tap water in a plurality of times in a washing mode and a rinsing mode after the start of washing to accurately adjust the amount of water. When the water absorption method and apparatus of the present invention are used in an automatic washing machine, the water absorption pump is activated in a plurality of times in the washing mode after the start of washing as in the normal use state of the automatic washing machine.

When water is supplied by being divided into a plurality of times,
Since water is supplied only for a short period of time because the amount of water is adjusted, it does not mean that the washing mode has been switched to the rinse mode. Therefore, the activation of the water absorption pump within the predetermined time is not counted in the number of activations. By doing so, it is possible to recognize that the washing mode has been changed to the rinsing mode.

In the present invention, it is not necessary to touch the main body of the automatic washing machine, but it is convenient to provide the main body of the washing machine with a water inlet for guiding the water drawn from the water suction pump into the washing machine. In particular, in the third embodiment, since the operation control of the water suction pump can be automatically performed, it is desirable to provide the water suction port in the automatic washing machine.

According to the first to third embodiments, as shown in FIG. 6, tap water is supplied in a small amount, but the bath water portion shown by the shaded portions saves tap water.

In order to add water from the water absorption pump to the existing automatic washing machine, the lid of the washing machine is slightly lifted and the end of the water absorption hose is inserted. It is desirable to flatten the washing machine side end of the water absorption hose in order to make the height of lifting the lid as low as possible. Optimally, a flat member should be connected to the tip of the hose.

Each automatic washing machine manufacturer is desired to provide a water intake port in the automatic washing machine in order to promote the use of bath water as washing water. Even now, there are housewives pumping bath water into an automatic washing machine using a water absorption pump (actually, my house uses a water absorption pump for every wash). There is a high consumer demand for installing a washing machine in an automatic washing machine.

Although applicable to all the embodiments, the electric power required for the pressure sensor, the water flow detection sensor, the signal processing circuits of these sensors, etc. may be supplied from the drive power source of the water absorption pump.

Although the member 1 is detachable from the water supply port or the water supply hose, it goes without saying that it may be formed integrally with the water supply hose. Further, in order to improve the use of bath water as washing water, it is desirable that the water absorption pump has a means for removing dust and the like from the bath water. It is possible to use charcoal. It is desired to have a simple means for removing dust in the bath water without adversely affecting washing.

[0048]

[Effect] By using the water absorption method and device for an automatic washing machine of the present invention, it is possible to automatically control the supply of bath water to the automatic washing machine without being manually operated. It is expected that the use of bath water as washing water will advance. Now that the importance of water resources is being screamed, we can once again return to the thrifty spirit of the idea of poverty.

Since it improves the usability of the water absorption pump in the automatic washing machine, the market of the water absorption pump expands, which leads to the promotion of small and medium-sized enterprises of the small and medium-sized household pump manufacturer who manufactures the water absorption pump.

The water absorption method and device for an automatic washing machine of the present invention can be used in all automatic washing machines of all manufacturers if the configuration of the invention according to claim 9 is applied. The best way to use it is to equip the automatic washing machine with a water inlet and connect a water suction hose. However, even in the existing automatic washing machine, the device of the present invention can be used as a timer to stop the water absorption pump when the water is full, and an effect can be expected.

A housewife using a water absorption pump without a timer went to the washing machine at a time when the water was full and stopped the water absorption pump. If it was not full, I had to wait by the washing machine until it was full. It's frustrating, even for a short time. It's like standing in front of an elevator and waiting with frustration to come early. The use of the device of the present invention also has the effect of relieving the housewife from this annoyance.

At present, a plurality of types of automatic washing machines are sold by a plurality of manufacturers. Consumers purchase automatic washing machines at their option. Within each consumer group that purchased various types of automatic washing machines from each manufacturer, there are qualitative consumers who want to use bath water for washing at a certain ratio. This is indirectly proved by the sale of simple water absorption pumps for using bath water as washing water at discount stores and the like.

Incorporate a water absorption pump into the automatic washing machine,
It is conceivable to add a function to control the water absorption pump. However, in doing so, the structure of the washing machine itself becomes complicated and expensive, and since there are some purchasers who are not willing to use such a function at all, the range of choice of consumers is wide. Will be narrowed. Therefore, it is better to add a water absorption method and device separated from the automatic washing machine according to the needs of consumers. The configuration of the present invention also has the effect of being able to meet the needs of this consumer.

Therefore, it is desired that each manufacturer of automatic washing machines has a water intake port in all types of automatic washing machines in order to meet consumer needs. When using bath water as washing water, housewives are likely to be at home during washing, so there is not much need to automate everything, and if bath water runs out, you can manually supply water from a water pipe. Switching is sufficient.

In the automatic washing machine, one wash,
It seems that many housewives drain the water as it is after rinsing. Therefore, without draining the water drained from the washing machine that is not so dirty like rinse water into the sewer,
If the child grows up and is no longer needed, it can be stored in a tub like a baby bath and used for a second wash to save even more water (this is already practiced at home). For that purpose, since it is necessary to use a water absorption pump, the convenience of the present invention is increasingly required.

Since the structure of the present invention can be used as it is without touching the main body of the washing machine, it can be used by all households who have already purchased the automatic washing machine. Households that currently own bath water suction pumps can incorporate only the control device for the water suction pump for washing machines.

Although water is gradually supplied from the water pipe, even if the bath water runs short,
There is no need to worry about washing being stopped on the way due to lack of water.
In addition, if a function to detect the water level in the bath and stop the alarm and / or the water absorption pump is added, the housewife will open the tap of the water pipe immediately after knowing that the function has been activated, and It is possible to switch to water supply from.

If the water supply from the water pipe is performed by a normal use method without squeezing the faucet of the water supply, and at the same time water is absorbed by the water absorption pump, the amount of water pumped into the washing tub per unit time is reduced. As it increases, there is a side effect that the total washing time is saved.
