Description

The invention relates to washing machines having a tank (s) for washing and rinsing washable products, and may find application in the design of household and industrial washing machines of drum and activator type.

Known washing machines having a tank for washing and rinsing. For example: drum-type washing machines (Lebedev A.I. "Anatomy" of washing machines. - M.: SOLON-PRESS (Series "Repair", issue 104), 2008, - 120 p.) / 1 /. Such machines include a housing and a rotatable drum fixed in the tank, a pump, a control system and equipment that wash, rinse and remove waste solutions and water after rinsing into the sewer.

Other washing machines having washing and rinsing tanks are also known. For example: activator-type washing machines (Household washing machines. V. A. Borodin, S. A. Likhachev / “BHV - St. Petersburg”, Dusseldorf, Kiev, Moscow, St. Petersburg, 1998, p. 38) II /, in which two containers are used: for washing, rinsing and spinning, as well as a pump for removing liquid, equipment and a control system.

The disadvantage of washing machines drum and activator type is the relatively high consumption of water for the washing and rinsing process. In such washing machines, multiple rinsing of the laundry is provided to remove residual detergent from the washing product, and after each rinse, the waste water is discharged into the sewer, and the next time you wash it, clean water from the water supply is used to prepare the washing solution. Such use of water is irrational. Water after the second rinse, and in some cases after the first rinse, can be used to prepare a washing solution for subsequent washing.

Known washing machines do not provide this capability, which is a disadvantage of these washing machines.

Closest to the technical nature of the claimed is a drum-type washing machine (Modern washing machines and detergents. N.A. Skorobogatov / BHV, St. Petersburg, Arlit, 2001, pp. 212-233) / 3 /, consisting from a housing, a rotatable drum located in the tank, an automatic reprogrammable control system, a pump, a valve for supplying water to the tank, a water supply line, a waste fluid outlet line to the sewer.

In such a washing machine, water is supplied to the tank from the water line under the pressure of this line by opening a valve programmatically controlled by the control system of the washing machine. The control system of such a washing machine also includes a sensor for filling the tank with water or another device that regulates the supply of the required volume of water to the tank for the preparation of the washing solution, this volume may depend on the volume of the tank loading the items being washed.

The control system of such a washing machine also programmatically controls the on / off of the pump, which ensures removal of the treated washing solution and water after rinsing into the sewer.

The disadvantage of such a washing machine is the relatively high water consumption for the washing process (including rinsing), which increases both the amount of water consumed and the amount of treated liquid discharged into the sewer. The objective of the invention is to reduce the amount of water consumed during washing.

The problem is solved in that the drum type washing machine, including a tank (s) and a drum for erasable items, a pump, control equipment providing a washing process, removing a washing solution, filling the tank with rinsing water and removing water after rinsing into the sewer, characterized in that the washing machine is equipped with a storage tank located above the tub for washing products, and the control equipment is equipped with two hydraulic flow distributors (hydrodistributors), one of which It is connected to the water supply line from the water supply system, to the storage tank and to the tank inlet, for filling the working fluid; the second valve is connected to the pump, to the storage tank and to the drain line of the spent fluid into the sewer.

The invention is illustrated by drawings. Figure 1 shows a diagram of a washing machine with storage capacity. The washing machine consists of a housing 1 with a tank and a drum 2, a pump 3, a first three-position valve 4, a second three-position valve 5, a storage tank 6, a hydraulic line 7. The washing machine is connected to a water line 8 and sewage 9.

In the initial state, the first three-position valve 4 is in the initial - first position (see Figure 1), the hydraulic lines 7 connected to it are not connected. In the second position, the first three-position valve distributes the hydraulic lines 7 from the pump 3 to the line 7 connected to the sewer 9. In the third position, the hydraulic valve 4 connects the hydraulic lines 7 from the pump 3 and the hydraulic line 7 connected to the storage tank 6.

In the initial state, the second three-position valve 5 closes the line 7 connected to the inlet to the tank 2, closes the line 7 connected to the water line 8, and closes the line 7 connected to the storage tank 6.

In the second position, the second three-position valve distributes the line 7 from the water line 8 with the inlet to the tank 2.

In the third position, the control valve 5 connects the line 7 from the storage tank 6 with the line 7 connected to the inlet to the tank 2.

The storage tank 6 is performed by a separate tank with a capacity of 8 ... 15 liters, fixed above the housing 1 of the washing machine. The storage tank can be made of two sections: for the accumulation of liquid after rinsing and the accumulation of washing solution for its reuse. The storage tank 6 is equipped with a sensor of the maximum filling level of the storage tank (not shown).

The washing machine operates as follows.

When the selected washing program is turned on, the tank 2 is filled with water from the water line 8 through the inlet of the tank 2. To perform this operation, the control program transfers the second three-position dispenser 5 from the first position to the second position, while line 7 from the water line 8 is connected to the input a hole in the tank 2 of the washing machine.

After switching the second three-position distributor 5 from the first position to the second position, the tank is filled with detergent solution, so that the control system controls the level of filling of the tank 2. When the set level is reached, the control program switches the control valve 5 to the first position, the water supply from the water supply line 8 is stopped.

Next, the algorithm of the washing program in the washing solution is executed in accordance with the selected program.

After completion of the washing program in the washing solution, the washing solution is drained into the sewer, while the first valve 4 is transferred to the second position; thereby connecting the output line 7 from the pump 3 to the drain line 7 to the sewer 9. After the washing solution is drained, rinsing is performed in accordance with the algorithm of the selected program.

An algorithm for directing the spent washing solution to one of the two sections of the storage tank is possible, for subsequent use.

For this algorithm, by the command "Save the washing solution", the first valve 4 is moved to the third position; thereby connecting the output line 7 from the pump 3 with the line 7 of the entrance to the storage tank 6.

After completing the second rinse (by default), or after the first rinse, when washing slightly dirty products (at the user's choice), the water is transferred from the tank 2 to the storage tank 6. If the container contains two sections, then to the water section after rinsing .

For this, the control system switches the first three-position valve 4 to the third position. In this case, line 7 is connected from the output of pump 3 to line 7 connected to the storage tank 6. By default, the control system generates a “drain into storage tank” command. The user command can replace this operation with draining the water from the tank to the sewer. To do this, the first three-position valve 4 is transferred to the second position, while the outlet of the hydraulic pump 3 is connected to line 7 connected to the sewer 9.

If the water level in the storage tank 6 is exceeded, by a signal from the level sensor, the control system switches the first three-position valve 4 to the second position, while the output from the pump 6 is connected to the sewer line 9. To remove liquid from the storage tank into the sewer, you can use a line with a shut-off valve (not shown in the diagram) with forced (manual) or software activation.

For the convenience of using the storage tank, it can be translucent for visual inspection of the degree of filling or to control the degree of filling using a level sensor.

After rinsing and moving the water to the storage tank, the process of processing the erased products is carried out in accordance with the selected program. The washing process is completed by removing the laundry from the drum 2 and turning off the washing machine. While the storage tank 6 contains a liquid for subsequent use. This liquid can be used both for subsequent washing and / or preparation of a washing solution, and for other household needs, for example, for filling the toilet flush tank. The storage tank may be equipped with a filter for cleaning the accumulated liquid.

The next time the washing machine is turned on, the control program generates a command to switch the second three-position distributor 5 from the first to the third position, while line 7 from the storage tank 6 is connected to the inlet of the tank 2 of the washing machine. The fluid moves by gravity from the storage tank 6 into the tank 2 of the washing machine. In this case, the control program monitors the sufficiency of water for the preparation of the washing solution. If it is sufficient, the flow of liquid from the storage tank 6 to the tank 2 is stopped by transferring the second three-position distributor 5 from the third position to the first - initial position, while the line 7 from the storage tank 6 is blocked from the entrance to the tank 2 of the washing machine.

In case of insufficient liquid from the storage tank 6, at the command of the water level sensor in the storage tank, the second three-position distributor 5 from the third position is transferred to the second position, while line 7 from the water main 8 is connected to line 7 connected to the inlet in the tank 2 of the washing machine. According to the signal from the level sensor of the washing solution in the tank 2, the water supply process is stopped by transferring the second three-position dispenser to its original - first position.

Next, the processing of linen continues in accordance with the program, and the operation "rinse" ends with filling the storage tank with water after rinsing, as previously described.

The described operating mode of the inventive washing machine can be supplemented or refined, including the integration of the control of accumulation of liquid after rinsing in various systems and algorithms for controlling washing and rinsing.

The use of a storage tank provides direct saving of water from the water supply line and reduces the discharge of not heavily contaminated water into the sewer, reducing the load on the sewer.

The implementation of the washing machine with a storage tank allows you to reuse slightly polluted water for the preparation of washing solution and / or use it for other household needs, for example, for a toilet flush tank.

A washing machine with a storage tank ensures the rational use of not only rinsing water, but also the rational use of washing solution after washing, for example for reuse of washing solution. In this case, the storage capacity of the washing machine can be made of two sections for accumulating water after rinsing and accumulating the spent washing solution. The accumulation of detergent solution, in some cases, can be used for subsequent washing, if the first washing was not heavily soiled items.

Used in the inventive washing machine, hydraulic equipment with electromagnetic control is integrated into the reprogrammable control systems of modern washing machines. It can be controlled as a system of automatic control of the washing and rinsing process available in the washing machine, so it can be controlled by a separate programmable controller.

The use of the storage tank for industrial machines, for example, in laundries, with a relatively large volume of water used in the washing process, will significantly reduce the cost of water for the washing and rinsing process and reduce the discharge of water into the sewer.
