[0023] The integrated cleaning center in this embodiment is only provided with one main water inlet and a main drain outlet, and the internal pipes are connected in parallel to meet the water supply and drainage needs of the sink functional area, the dishwashing functional area and the water purification functional area, so as to realize the interconnection of the connecting pipes between the various equipments, simplify the internal pipe configuration of the integrated cleaning center, and correspondingly make it more convenient and quick to assemble the pipe elements and working components of the three functional areas, and the overall space occupied is small, the weight is light, and the manufacturing cost can be effectively reduced.

[0024] Specifically, the sink functional area includes a sink, a sink faucet and a sink drain. The sink faucet is installed on the edge of the sink and is connected to the main water inlet through the sink water inlet pipe; the sink drain is installed at the bottom of the sink and is connected to the main drain through the sink drain pipe. It should be understood that the sink drain pipe is installed vertically so that the water in the sink can flow to the main drain under the action of its own gravity.

[0025] In this embodiment, the sink is made of stainless steel, and its main functions are to wash vegetables, cut vegetables and drain water. When the user turns on the sink faucet, the external tap water is diverted through the cross pipe fitting at the main water inlet end under the pressure of the tap water pipeline, and flows along the sink water inlet pipe to the sink faucet. The tap water can be used by the user after flowing out of the sink faucet, and the used sewage is discharged from the main drain outlet through the sink drain pipe from the sink drain at the bottom of the sink under the action of its own gravity.

[0026] Specifically, the dishwashing function area includes a dishwasher, the water inlet of the dishwasher is connected to the main water inlet through a dishwashing water inlet pipe, and the water outlet of the dishwasher is connected to the main drain through a dishwashing water outlet pipe; a first solenoid valve is installed on the dishwashing water inlet pipe, and the first solenoid valve is used to open and close the water supply channel of the dishwasher, and a first check valve is also installed on the dishwashing water inlet pipe corresponding to the first solenoid valve and the dishwasher, and the first check valve is used to prevent water backflow inside the dishwasher; a drainage pump is installed on the dishwashing water outlet pipe, and the drainage pump is used to discharge sewage.

[0027] In this embodiment, a water softener is further provided on the dishwashing water inlet pipe corresponding to between the check valve and the dishwasher. The water softener can soften the tap water input into the dishwasher, thereby improving the cleaning effect of the dishwasher.

[0028] In this embodiment, the dishwasher includes a dishwashing tank and a drainage tank that are interconnected, and the dishwashing tank and the drainage tank are both formed by stretching stainless steel; multiple layers of dishwashing baskets are horizontally arranged in the dishwashing tank, and a dishwashing spray arm is installed above each layer of the dishwashing basket; the drainage tank is installed at the lower part of the dishwashing tank, the drainage tank is connected to the water softener, and the drainage tank is connected to the dishwashing spray arm through a pipe, and a circulation pump is installed on the connecting pipe between the drainage tank and the dishwashing spray arm.

[0029] In this embodiment, a heater is installed on the connecting pipe between the drainage tank and the circulation pump, and the heater is used to heat the cleaning water input into the dishwasher to improve the cleaning effect.

[0030] It should be understood that the integrated cleaning center in this embodiment is also equipped with a control system, which includes a display and a controller, wherein the display is used to display the working status of the relevant functional area, and the user needs to issue a dishwashing instruction through the dishwashing button on the display; the controller is used to control the opening and closing of the first solenoid valve, water softener, circulation pump, heater, and drainage pump in the dishwashing functional area.

[0031] In combination with all the technical features of the dishwashing function area mentioned above, the overall working principle is described as follows: when the user presses the dishwashing button on the display, the first solenoid valve is automatically opened, and the external tap water is diverted through the cross pipe at the main water inlet end under the pressure of the tap water pipeline, and flows through the first check valve along the dishwashing water inlet pipe, and then flows into the water softener, in which the tap water is softened, and the softened water enters the heater through the drain groove at the bottom of the dishwashing tank, and the softened water is heated to about 70° C. by the heater, and then the hot water is transported to the dishwashing spray arm by the pressure generated by the circulation pump, and the hot water is sprayed from the dishwashing spray arm to wash the tableware placed on the dishwashing basket, and the washing water will flow into the drain groove from the bottom of the dishwashing tank again, and then circulate through the heater, the circulation pump and the dishwashing spray arm to wash the tableware multiple times; after the cyclic washing program is completed, the drainage pump is started to discharge the washing sewage from the main drain outlet, and then the tap water is re-input to repeat the above process until the entire washing program is completed.

[0032] Specifically, the water purification functional area includes a composite filter element, an RO membrane filter element and a water purification faucet. The water inlet end of the front filter portion of the composite filter element is connected to the total water inlet, the water outlet end of the front filter portion of the composite filter element is connected to the water inlet end of the RO membrane filter element, the purified water outlet end of the RO membrane filter element is connected to the water inlet end of the rear filter portion of the composite filter element, and the water outlet end of the rear filter portion of the composite filter element is connected to the water purification faucet; the waste water outlet end of the RO membrane filter element is connected to the total drain port; in this embodiment, the composite filter element is used to filter solid particles in tap water, and the RO membrane filter element removes impurities such as dissolved salts, colloids, microorganisms, organic matter, etc. in tap water through reverse osmosis technology.

[0033] In this embodiment, a second solenoid valve and a booster pump are installed in sequence along the water flow direction on the connecting pipeline between the water outlet end of the front filter part of the composite filter element and the water inlet end of the RO membrane filter element; a high-pressure switch is installed on the connecting pipeline between the water outlet end of the RO membrane filter element and the water inlet end of the rear filter part of the composite filter element, and the high-pressure switch is used to detect the pressure in the pipeline.

[0034] In this embodiment, a second check valve is further installed on the connecting pipeline between the purified water outlet of the RO membrane filter element and the water inlet of the rear filter part of the composite filter element, and the second check valve is used to prevent the purified water at the composite filter element from flowing back to the RO membrane filter element.

[0035] In this embodiment, a third solenoid valve is installed on the connecting pipeline between the wastewater outlet end of the RO membrane filter element and the main drain port, and the third solenoid valve is used to discharge the wastewater generated after filtering through the RO membrane filter element.

[0036] It should be understood that the second solenoid valve, the third solenoid valve, the high-pressure switch and the boost pump are all electrically connected to the above-mentioned controller, and the controller is used to receive the pressure signal from the high-pressure switch, and then control the opening and closing of the second solenoid valve, the third solenoid valve and the boost pump.

[0037] In combination with all the technical features of the water purification functional area mentioned above, its overall working principle is described as follows: when the user turns on the water purification faucet, as the remaining water in the connecting pipeline between the RO membrane filter element and the water purification faucet flows out, the pressure inside this part of the pipeline decreases. At this time, the high-pressure switch senses that the pipeline pressure value drops to the set value, and the second solenoid valve opens. Under the pressure of the tap water pipeline, the external tap water is diverted through the cross pipe fitting at the total water inlet end, and flows along the water purification pipeline to the front filter part of the composite filter element for initial filtration. At the same time, the booster pump is started to pass through the composite filter element. The clean water after preliminary filtration is input into the RO membrane filter element for reverse osmosis filtration. The clean water after filtration by the RO membrane filter element enters the post-filtration part of the composite filter element through the high-pressure switch, and flows to the clean water faucet for users after being filtered again. When the user turns off the faucet, the booster pump is still in operation until the entire pipeline is filled with water. When the high-pressure switch senses that the pipeline pressure value rises to the set value, the second solenoid valve and the booster pump are closed to stop the water supply. In this process, the waste water generated during the operation of the RO membrane filter element is discharged from the main drain outlet through the third solenoid valve.

Below the bottom plate of the dishwashing tank is the installation space for the water softener, heater, circulation pump, drainage pump and other components. The first check valve is installed on the outside of the back of the dishwashing tank. The arrangement and installation method of the dishwashing basket, spray arm and other components inside the dishwashing tank are consistent with those of conventional dishwashers and will not be repeated here. The water purification functional area adopts an integrated water circuit board to integrate and install all components. The integrated water circuit board is fixedly connected to the rear sealing plate. The composite filter element, the second electromagnetic The valve, RO membrane filter element, high-pressure switch, third solenoid valve and other water circuit components are all installed at corresponding positions on the integrated water circuit board. The composite filter element and RO membrane filter element are equipped with matching filter element seats. The front end of the filter element seat is supported by the filter element bracket, and the filter element is sealed and installed in the filter element seat; the booster pump is fixedly installed on the bottom plate through a shock-absorbing pad; the upper end of the integrated water circuit board is provided with a clean water outlet, and the clean water outlet is connected to the clean water faucet installed on the side of the sink; the lower end of the integrated water circuit board is provided with a clean water inlet and a waste water outlet, and the clean water inlet and the waste water outlet are respectively connected to the total water inlet and the total drain outlet; the total water inlet and the total drain outlet are both arranged on the rear sealing plate to facilitate the installation of external tap water pipes and sewage pipes.
