When the longitudinal movement frame moves downwards, the linkage head is along the guide frame slides, and the linkage head drives the transverse movement frame to move away from the water flowing column direction.

When the longitudinal moving frame moves upwards, the linkage head slides along the guide frame, and the linkage head drives the transverse moving frame to move towards the direction close to the water passing column.

One end of the transverse moving frame, which is close to the sealing cover, is fixedly connected with a first sliding head which is in sliding connection with the lower end face of the sealing cover; and the lower end surface of the sealing cover is connected with a lower sliding block which is mutually attracted with the upper sliding block and the first sliding head respectively in a sliding manner.

The lower sliding block, the upper sliding block and the first sliding head are all made of magnets; an attractive force between the lower slider and the upper slider is greater than an attractive force between the lower slider and the first slider.

Compared with the prior art, the invention has the beneficial effects that: in the initial state of the invention, the cleaning part is in a vertical and slightly outward inclined state.

When a user needs to wash the dishes, the user puts one surface of the dish to be washed on the washing part and presses the surface downwards, the water passing column starts to move downwards, the spring is compressed, and the linkage head is simultaneously positioned in the first sliding groove, the second sliding groove and the third sliding groove; the first sliding head and the lower sliding block are mutually attracted through the magnet, so that the lower sliding block moves along with the first sliding head, the lower sliding block is mutually attracted through the magnet with the upper sliding block, the upper sliding block moves along with the lower sliding block, and the cleaning part is always in a linear state and gradually abuts against the plate.

Then, a dish washing button on the shell is pressed, so that the controller controls the motor to rotate in the forward direction, the driving gear is meshed with the side wall teeth to drive the rotating box to rotate in the forward direction, and the rotating box drives the cleaning part arranged at the upper end of the water through column to rotate in the forward direction.

Meanwhile, the water pipe is communicated with the water inlet pipe of the pump shell, and clean water enters the centrifugal water pump; an output shaft of the motor is in transmission connection with the transmission wheel through a belt, the transmission wheel is driven to rotate in the forward direction by forward rotation of the motor, the transmission wheel drives the first impeller to rotate in the forward direction, so that water in the first pump shell forms forward-rotating water flow under the rotation of the first impeller, then the water flow pushes the push head and drives the reversing sleeve to rotate in the forward direction, and the limiting block slides in the reversing groove; when the limiting block is abutted against the forward end face of the reversing groove, the first water outlet is just communicated with the first water through opening, the second water outlet is not communicated with the second water through opening, clean water flows out of the first water outlet and enters the mixed water tank through the water inlet, the second impeller starts to rotate under the pushing of water flow and drives the pump body assembly to start working, detergent is pumped into the second pump shell from the detergent pipe and then extruded into the mixed water tank from the second pump shell, mixed liquid formed by mixing the detergent and the clean water flows out of the third water outlet and enters the water through pipe, then flows into the first water through pipe from the water through pipe, then flows into the second water through pipe from the water through opening on the side wall, and finally is sprayed out of the central water spray pipe and the water spray pipe onto a plate for cleaning.

After a set time, the controller controls the motor to rotate reversely, the first impeller starts to rotate reversely, water flow in the first pump shell drives the reversing sleeve to rotate reversely, when the limiting block abuts against the reverse end face of the reversing groove, the second water outlet is just communicated with the second water through opening, the first water outlet is not communicated with the first water through opening, clean water flows into the water through pipeline from the first pump shell, then flows into the second water through pipe and the side wall water through opening, and finally is sprayed out of the central water spray pipe and the water spray pipe onto a plate to wash out residual mixed liquid.

After the cleaning is finished, the dish is taken down, the longitudinal moving frame rises under the action of the elastic force of the spring to drive the linkage head to slide along the second sliding groove, so that the first sliding head pushes the lower sliding block to be gradually close to the water through column, the driving assembly resets, and the cleaning part resets.

When the user need wash the dishes, put the bowl on the cleaning part and press down earlier, it begins the downstream to lead to the water column, the spring is compressed, it is in-process to lead to the water column downstream, because the inner wall of bowl offsets with cleaning part upper portion, consequently, the top shoe can not remove, because bottom shoe and top shoe inter attraction, consequently, the bottom shoe also can not remove and remove, make first slider and bottom shoe separation, first slider removes to the direction of keeping away from logical water column, under the effect of flexure strip, make the cleaning part finally be the inner wall counterbalance of curvilinear condition and bowl.

Meanwhile, the water pipe is communicated with the water inlet pipe of the pump shell, clear water enters the first pump shell and forms forward rotating water flow under the rotation of the first impeller, then the water flow pushes the pushing head and drives the reversing sleeve to rotate forward, and the limiting block slides in the reversing groove at the moment; when the limiting block is abutted to the forward end face of the reversing groove, the first water outlet is just communicated with the first water through opening, clear water flows out of the first water outlet and enters the mixed water tank through the water inlet, the second impeller drives the pump body assembly to work to extrude detergent into the mixed water tank to be mixed with the clear water to form mixed liquid, and finally the mixed liquid is sprayed out of the central water spray pipe and the water spray pipe to the inner wall of the bowl to perform cleaning work.

After a set time, the controller controls the motor to rotate reversely, the first impeller starts to rotate reversely, water flow in the first pump shell drives the reversing sleeve to rotate reversely, when the limiting block abuts against the reverse end face of the reversing groove, the second water outlet is just communicated with the second water through opening, clean water flows into the water through pipeline from the first pump shell, then flows into the second water through pipeline and the side wall water through opening, and finally is sprayed out of the central water spray pipe and the water spray pipe to the inner wall of the bowl, so that residual mixed liquid is washed clean.

After the cleaning is finished, the dish is taken down, the driving assembly resets under the action of the elastic force of the spring, the cleaning part is restored to be in a vertical state under the action of the elastic sheet, and the first sliding head and the lower sliding block are abutted again.

The motor is arranged, so that the rotation of the motor can drive the rotation of the rotating box and the rotation of the cleaning part, and the centrifugal water pump can be driven to work to spray water flow for cleaning.

The invention enables the centrifugal water pump to select the flow direction of the clear water by arranging the reversing sleeve, so that the spray pipe sprays the clear water or the mixed liquid.

According to the invention, the magnets which attract each other are respectively arranged between the first sliding head and the lower sliding block and between the lower sliding head and the upper sliding block, so that the cleaning part is linear when washing dishes and is curved when washing dishes.

According to the invention, the center of the dish or the bottom of the bowl can be cleaned in the cleaning process by arranging the center cleaning seat, so that the cleaning efficiency is improved.
