Description

The utility model relates to household appliances, namely to the construction of ultrasonic washing machines, and can be used in industrial laundries, as well as at home [IPC D06F19 / 00].

A WASHING MACHINE is known from the prior art [SU153717 (A1), publ. 06/18/1963], containing a housing with a sealed cover, a chamber located inside the housing with a horizontal perforated partition for material placement, a vibration drive connected to the chamber, and a means for creating a vacuum connected through a valve to the upper part of the chamber.

The disadvantage of the analogue is: when using this technical solution, a washing solution is used for washing, which requires the use of a rinse mode.

Implementation of the utility model

Consider one of the possible options for the implementation of the claimed technical solution. The washing machine consists of a washing machine body 1 with a sealed door 2, which has a washing mode selection knob 3, a start button 4 and an operation status display panel 5 on the outside in the upper part. with control automatics 6, connected by the first wire cable 7 with an electric motor 8, which communicates with the washing chamber 9 installed in the middle of the body of the washing machine 1 by a belt drive 10. Also, the power supply unit with the control automatics 6 is connected with a second wire cable 11 attached to the sealed door 2 by an ultrasound generator 12, third and fourth wire cables 13, 14 with a block of control valves 15 and a pump 16 located in the rear of the washing machine 1 housing, respectively. Inside the power supply unit with control automatics 6, a comparator 17 is mounted, which is connected by the fifth and sixth wire cables 18, 19 to the first turbidity meter 20 and the second turbidity meter 21. In turn, the first and second turbidity meters 20, 21 are connected on one side with water pipes with a filter 22, and on the other hand, the first turbidity meter 20 with a washing chamber 9, and the second turbidity meter 21 with a block of controlled valves 15. In the lower part of the washing machine body 1, a water tank 23 is mounted, which is connected by the first water pipe 24 to the pump 16 and the second a pipe for water 25 with a block of controlled valves 15. Also, a pipe for filling water 26 enters the water tank 23. In addition, the pump 16 is connected by the third and fourth pipes 27 and 28 to the block of controlled valves 15, and the block of controlled valves 15 itself is connected by the fifth nozzle 29 with a washing chamber 9.

The washing machine is used as follows.

Initially, water is poured into the water tank 23 into the washing machine through the water inlet pipe 26, with a volume, depending on the version, from 0.08 to 0.11 cubic meters. m. Then, the laundry is immersed in the washing chamber 9 and the sealed door is closed. pressing the start button 4 the power supply unit with control automation 6 via the fourth wire cable 14 gives a command to the pump 16, which pumps water from the water tank 23 into the washing chamber 9 through the first water connection 24, the third water connection 27, the controlled unit valves 15, which controls the flow of water during various operating modes of the washing machine, the fourth water nozzle 28 and the fifth water nozzle 29. Also, the power supply unit with control automatics 6 through the first wire cable 7 issues a command to start the electric motor 8, which rotates the camera for wash 9 using belt drive 10, simultaneously turns on through the second and third wire cables 11, 13, the ultrasound generator 12 and the control valve block 15. In this version, the ultrasound generator 12 is attached to the sealed door 2 to create conditions for sealing and maximally approaching the emitting elements to the mass of water with the washed laundry 2. In this case, the ultrasound generator 12 creates a cavitation mode in the entire volume of water in the washing chamber 9, in which the separating particles of dirt and grease are removed by water and retained in the filter 22.

In the washing mode, the pump 16 circulates water through the water pipes from the washing chamber 9 through the first turbidity meter 20, where the water transparency level is measured, the filter 22, which purifies the water, the second turbidity meter 21, which gives the water transparency value through the sixth wire cable 19 to the comparator 17, the block of controlled valves 15, the fourth pipe for water 28, the pump 16 and back to the washing chamber 9. The washing is stopped at the moment when the values of the water transparency, transmitted to the comparator 17 from the first turbidity meter 20 and the second turbidity meter 21, coincide.

After the end of the washing cycle, the spin mode is turned on, in which, as a result of the rotation of the washing chamber 9, the pump 16 pumps out water, while the water passes through the first turbidity meter 20, the filter 22, the second turbidity meter 21, the control valve block 15, which directs water through the second pipe for water 25 back to the water tank 23. The mode operates at a predetermined time, according to the selected mode.

Thus, the use of the investigated technical solution makes it possible to achieve the claimed technical result.

In addition, the technical solutions used make it possible to increase the reliability of the structure due to the use of a control valve block 15, made with the possibility of distributing the flows of water circulating in the circuit of the washing machine. Also, the reliability of the design is achieved through the use of a comparator 17 mounted inside the power supply with control automation 6, which is connected with wire cables to the first and second turbidity meters 20, 21, made with the possibility of transferring to the comparator 17 for comparing the values of the degree of water transparency, including, on the basis of which a decision is made about the cleanliness of the laundry, which allows you to achieve the minimum sufficient washing time.
