Description
Technical Field
The utility model belongs to a washing machine.
Background
Conventionally, in a region with extremely hard water quality, when washing with raw water (hereinafter referred to as raw water) having hardness exceeding 100ppm such as tap water, well water, and underground water, it has been necessary to add a slightly larger amount of detergent than the standard use amount recommended by washing machine manufacturers and detergent manufacturers. The residual components of the detergent are not completely removed after the rinsing process, and if the laundry to which the residual components are attached is dried, the gloss of the laundry is lost, and if the laundry is a heat-resistant material, the heat-resistant effect is reduced, and the laundry is yellowed by soap marks.
There are many examples of solving this problem. For example, a technique of improving the washing effect by installing a non-diaphragm type electrolytic cell in a washing tank and electrolyzing raw water in the washing tank to promote dissolution of a detergent and generate washing water containing hypochlorous acid (for example, as reported in Japanese patent publication No. 49-14173).
For example, there is a technique of electrolyzing raw water in a diaphragm type electrolytic bath provided in an electric washing machine, washing clothes with electrolytic water (alkaline water) generated on the electrode side of a cathode plate, and rinsing clothes with electrolytic water (acidic water) generated on the electrode side of an anode plate (for example, as reported in Japanese patent laid-open No. 5-84384). Similarly, there is a technique of improving a method of feeding electrolytic water (alkaline water) generated on the electrode side of the cathode plate and electrolytic water (oxidized water) generated on the electrode side of the anode plate by installing a plurality of electromagnetic water feeding valves (for example, as reported in Japanese patent No. 3385693).
For example, a technique of electrolyzing raw water in a diaphragm type electrolytic bath provided in an electric washing machine to remove anions or cations in the raw water and then feeding the water into the washing bath (for example, as reported in Japanese patent No. 2906578). Similarly, there is a technique of electrolyzing raw water in a diaphragm type electrolytic bath provided in an electric washing machine to remove metal ions in the raw water (softening treatment), and then adding an anionic surfactant to the water to bring the water into contact with clothes (for example, as reported in Japanese patent No. 3154765).
For example, japanese patent application laid-open publication nos. 64-36777 and 7-113100 disclose techniques in which a chemical adding device or the like is provided in an outlet portion on the cathode plate electrode side of a diaphragm type electrolytic cell, and a chemical such as a surfactant is automatically added to electrolytic water (alkaline water) generated on the cathode plate electrode side.
In addition, in the conventional electric washing machine using a liquid detergent, a liquid detergent feeding device and an electric circuit control device for controlling the injection of raw water are used to add a substantial amount of the liquid detergent from a liquid detergent tank to the raw water and dilute the liquid detergent to generate washing water having a predetermined concentration.
The conventional techniques were examined, and the following examples were given. For example, a liquid detergent dispenser for dispensing a predetermined amount of liquid detergent into a washing chamber (for example, as reported in Japanese patent application laid-open No. Sho 61-272096). For example, a liquid detergent dispenser device for metering a liquid detergent in a cylinder having 2 check valves and sucking and dispensing the liquid detergent (for example, as reported in Chinese Utility model No. CN 2491474Y and Japanese patent application laid-open No. 9-206493). Such as a liquid detergent dispenser device for controlling the amount of liquid detergent to be dispensed by controlling the operation time of an air pump (for example, as reported in chinese utility model CN 2463424Y). For example, a liquid detergent dispenser is known in which a liquid detergent filled in a container is pressurized to control the opening time of a valve, thereby controlling the amount of detergent to be dispensed (for example, as reported in Japanese patent application laid-open No. 8-229293).
However, in the past, the amount of liquid detergent flowing out from various liquid detergent dispensing devices and the like was unstable, and it was not possible to generate washing water of a set concentration.
First, from the environmental point of view, it is desirable to wash with washing water having the lowest concentration, but since the metering accuracy of the liquid detergent dispenser is low, there is a problem that the actual amount of the liquid detergent to be dispensed is larger than the amount recommended by manufacturers such as washing machines, electric dishes, washing dryers, and detergent manufacturers.
Secondly, the liquid detergent hardly flows out, and it takes a long time for the measured liquid detergent to flow out completely, and it is difficult to cut the detergent by making a drop by a click.
The electric washing machine equipped with an electrolytic cell disclosed in the prior art mentioned above is not actually marketed, and the function and utilization effect of the electrolytic water cannot be exhibited.
The Chinese utility model patent application No. 03143357.X, which is applied by the applicant but not yet published, describes a technical scheme of a washing machine with an electrolytic bath, which can solve the problems of excessive detergent feeding amount, inaccurate liquid detergent feeding amount, overlong feeding time and difficulty in rapidly cutting off liquid drops, but has the structural disadvantages: when the washing machine works, raw water flows into the electrolytic tank through the electromagnetic water supply valve through the pipeline, electrolytic water (alkaline water) generated on the cathode plate side of the electrolytic tank flows out of the cathode outlet and flows to the water inlet of the four-way switching valve through the pipeline, and the electrolytic water is mixed with detergent flowing out of the detergent tank and flowing to the liquid inlet of the four-way switching valve through the pipeline in the metering chamber and flows out of the water outlet of the four-way switching valve and flows to the washing tank through the pipeline; the result would be: ca (HCO) in hard water3)2、MgCl2OH in alkaline water-Formation of water-insoluble compounds:
the compound is attached to a cathode plate of an electrolytic cell for generating electrolytic water after the washing is finished, and a square switching valve and a pipeline which are correspondingly connected are flowed by alkaline water. After the long-time operation, the scale on the electrode plate of the electrolytic cell reduces the effective electrolytic area on the electrode plate, thereby influencing the electrolytic efficiency of the electrolytic cell; and the scale on the four-way switching valve reduces the volume of the metering chamber, so that the metering precision of the four-way switching valve is influenced, and even a large amount of scale can block a water outlet to cause the four-way switching valve to fail.
If the washing process is finished, the raw water is injected into the electrolytic tank and remains in the electrolytic tank, and a reverse DC voltage is applied to the electrolytic tank for a period of time to fill the cathode plate with high-concentration acid water and dissolve CaCO generated by electrolysis3、Mg(OH)2The scaling substances are discharged when the next time water is supplied to the electrolytic cell, and the scaling in the electrolytic cell can be avoided.
If the electrolyzed water is directly fed into the washing tank without passing through the four-way switching valve and the raw water flowing into the four-way switching valve is directly supplied by the electromagnetic water feed valve, the scale will not be formed in the four-way switching valve.
However, the electrolytic cell does not have the function of water storage after the water paths of the electrolytic cell and the four-way switching valve are separated, namely after the electromagnetic water supply valve is closed, the liquid level of the cathode outlet of the electrolytic cell or the pipeline connected with the cathode outlet, the liquid level of the three-way member communicated with the atmosphere in the electrolytic cell is higher than the liquid level of the anode outlet of the electrolytic cell or the pipeline connected with the anode outlet of the electrolytic cell, the three-way member communicated with the atmosphere, and the pressure difference between the two sides ensures that the electrolytic cell cannot be reserved and emptied after raw water is injected into the electrolytic.
Disclosure of Invention
The utility model discloses thereby solve the electrode plate scale deposit of above-mentioned electrolysis trough and influence the electrolysis efficiency of electrolysis trough and the scale deposit of cubic diverter valve and reduced thereby the volume of measurement room influence the measurement precision of cubic diverter valve, a large amount of scales can block up the problem that the delivery port made cubic diverter valve inefficacy even, provide for this the utility model discloses a load the electric washing machine of electrolysis trough.
In order to solve the problems, the design of the utility model considers that ① directly inputs electrolyzed raw water into a washing tank without passing through a square switching valve, the raw water flowing into the square switching valve is directly provided by an electromagnetic water supply valve, so that no scale is formed in the square switching valve, ② injects the raw water into the electrolytic tank and retains the raw water in the electrolytic tank after the washing process is finished, and can apply reverse direct current voltage to the electrolytic tank, so that the side of a cathode plate is filled with high-concentration acid water for a period of time to dissolve scales generated by electrolysis.
Therefore, the technical proposal adopted by the electric washing machine with the electrolytic bath of the utility model is that the box body is provided with a washing tank, an electromagnetic water feeding valve, an electrolytic bath, a liquid detergent tank, a four-way switching valve, a three-way connecting piece and a circuit control device which are composed of an outer tank and an inner tank driven by a motor to rotate, and the electric washing machine is characterized in that:
① the water outlet end of the electromagnetic water supply valve is connected with the water inlet of the electrolytic tank through a pipeline A, the cathode water outlet of the electrolytic tank is connected with the water inlet of the washing tank through a pipeline B, the water outlet end of the electromagnetic water supply valve is connected with the water inlet of the four-way switching valve through a pipeline G, the liquid detergent outlet of the liquid detergent tank is connected with the liquid inlet of the four-way switching valve through a pipeline C, and the water outlet of the four-way switching valve is connected with the water inlet of the washing tank through a pipeline D;
② height D of three-way connector connected with anode outlet of electrolytic tank, water outlet of square switching valve and water outlet of washing machine2And the lowest point of a pipeline B connected with a cathode water outlet of the electrolytic bath is positioned at a height D1Has the relationship: d1-D2≤200mm。
Of course D is also possible1Less than or equal to D2。
The relationship in ② indicates D1May be greater than D2200mm, but not larger than the original size, otherwise, the raw water injected into the electrolytic cell is emptied and can not be stored, and the reverse electrolysis can not be carried out. According to the principle of the communicating vessel, the free liquid level of the same liquid in the communicating vessel is the same, namely after the electromagnetic water supply valve is closed, if the liquid level in the cathode outlet of the electrolytic cell or the pipeline connected with the cathode outlet, the three-way member and the atmosphere is the same as the liquid level in the anode outlet of the electrolytic cell or the pipeline connected with the anode outlet, the three-way member and the atmosphere, the water in the electrolytic cell cannot be discharged. Because the cathode outlet of the electrolytic cell is directly communicated with the atmosphere through the pipeline, the anode outlet is connected with the four-way switching valve through the three-way piece, and the circuit control device controls the opening of the four-way switching valve to realize the communication with the atmosphere, the structure should be that the lowest position of the cathode outlet of the electrolytic cell or the pipeline connected with the cathode outlet of the electrolytic cell is equal to the height of the anode outlet or the three-way piece connected with the anode outlet of the electrolytic cell, so that the water in the electrolytic cell can not be discharged, but tests show that D1The maximum limit can be larger than D2200 mm. This is based on the fact that:
when the washing is finished, the electromagnetic water-feeding valve is opened to feed water into the electrolytic tank, and then closed, and when the reverse DC voltage is applied to the electrolytic tank by the circuit control device, about twice as much gas is generated on the side of the cathode plate as on the side of the anode plate due to the electrolysis of water
It is known from the law of avocado that, if the solubility of oxygen and hydrogen in water is neglected, the volume of hydrogen generated by electrolysis is twice as much as that of oxygen under the same temperature and pressure. (1 volume of water at 1atm, 20 ℃ C. can dissolve 0.031 volume of oxygen and 0.018 volume of hydrogen). The generated gas is gathered at the cover part of the electrolytic cell. The test results confirmed that when a reverse DC voltage was applied to the electrolytic cell for a certain period of time by the circuit control device, and acid water was formed at a concentration sufficient to dissolve scale on the cathode plate side, the gas generated by electrolysis on the anode plate side accumulated on the lid portion of the electrolytic cell was brought to a gas pressure about equivalent to a water column pressure of 200 mm.
