[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] This embodiment discloses an energy-saving dishwasher, referring to... Figure 1-7 As shown, the dishwasher includes a washing chamber 10, a water cup 1, a water outlet pipe, and a water supply pipe 8. The washing chamber 10 is the main washing unit inside the dishwasher and is mainly composed of an inner tub. The water cup 1 is located at the bottom 14 of the washing chamber 10, and the opening 11 at the top of the water cup 1 is connected to the washing chamber 10 to collect water from the bottom 14 of the washing chamber 10.

[0030] The water cup 1 is connected to a water supply pipe 8 and a water outlet pipe. The water outlet pipe is used to drain the water from the water cup 1. A drain pump 4 is installed in the water outlet pipe. The first end 41 and the second end 42 of the drain pump 4 are connected to the water outlet pipe, allowing water in the water outlet pipe to flow through the drain pump 4. The drain pump 4 provides power to the water in the water outlet pipe, allowing the water to be drained after the dishwasher has finished washing.

[0031] Water supply pipe 8 supplies water to the dishwasher for washing within the washing chamber 10. A water supply pump 5 is connected to water supply pipe 8, with its first end 51 and second end 52 connected to the water supply pipe 8, allowing water to flow through it. The water supply pump 5 provides power to the water in the water supply pipe 8, pumping the washing water out. A spray unit 7 is installed inside the washing chamber 10, and the water supply pipe 8 is connected to it, supplying water to the spray unit 7. The water is then sprayed out from the spray unit 7, providing a spray washing effect.

[0032] An interface 53 is provided on the upper edge of the water cup 1 for connection to the water supply pipe 8. The specific configuration can be adjusted according to the internal structure of the dishwasher.

[0033] In addition, a heating element 6 is installed on the water supply pipe 8 to heat the washing water. The heating element 6 can generate heat. The water in the water supply pipe 8 can flow through the heating element 6, thereby heating the water in the water supply pipe 8, so that the dishwasher can achieve the function of hot water washing during the washing process.

[0034] Specifically, the water cup 1 has an outlet 12 and an outlet 13 on its side wall. Outlet 12 is lower than outlet 13. Outlet 12 is connected to a water outlet pipe, and outlet 13 is connected to a water supply pipe 8. A sealing plate 2 is installed inside the water cup 1. The outline of the sealing plate 2 is adapted to the outline of the inner circumference of the water cup 1, so that the sealing plate 2 and the inner wall of the water cup 1 can achieve a sealing fit.

[0035] An annular sealing part 21 can be installed on the outer periphery of the sealing plate 2. The sealing part 21 can be a rubber sealing ring, so that the sealing plate 2 and the inner periphery of the water cup 1 form a piston-like sealing connection structure. The sealing plate 2 can divide the inner cavity of the water cup 1 into chamber one 101 and chamber two 102. Chamber one 101 is located on the upper side of the sealing plate 2, and chamber two 102 is located on the lower side of the sealing plate 2.

[0036] When the dishwasher is working, water is stored in the upper chamber 101.

[0037] The sealing plate 2 can be adjusted up and down relative to the water cup 1 by the drive component 3. The sealing plate 2 is adjusted to a position between the first water outlet 12 and the second water outlet 13. This position is called position two. (Refer to...) Figure 4As shown, the outlet 12 is disconnected from the chamber 101. The sealing plate 2 is adjusted to a position lower than the upper edge of the outlet 12; this position is position one, as shown in the reference diagram. Figure 5 As shown, the outlet 12 is connected to the chamber 101.

[0038] When the dishwasher is working, the sealing plate 2 can be adjusted between position one and position two. When the sealing plate 2 is adjusted upward, the water outlet can be disconnected from the chamber 101 of the water cup 1 and the water supply pipe 8. When heating the water in the dishwasher, the total amount of water circulating in the water supply pipe 8 can be reduced, avoiding heat exchange with the water in the drain pipe 9, thereby improving the heating efficiency of the washing water in the dishwasher and improving the heating energy efficiency.

[0039] When the water in the water cup 1 inside the dishwasher needs to be drained, the sealing plate 2 can be adjusted downwards so that the height of the sealing plate 2 is adjusted to the lower side of the water outlet 12, so that the water outlet 12 can communicate with the upper chamber 101 of the sealing plate 2, allowing the water inside the dishwasher to be drained, thereby realizing the drainage of wastewater inside the dishwasher.

[0040] Furthermore, the upper surface of the sealing plate 2 is inclined downward toward the outlet 12, which allows the water in the sealing plate 2 to flow more smoothly toward the outlet 12, facilitating the discharge of water from the cup 1 to the outlet 12.

[0041] In order to achieve the up-and-down adjustment of the sealing plate 2, a through hole 15 can be opened at the bottom 14 of the water cup 1, and a movable rod 22 is fixedly connected to the lower part of the sealing plate 2. The movable rod 22 passes through the through hole 15 and extends to the bottom 14 of the water cup 1.

[0042] A seal 16 is installed between the movable rod 22 and the through hole 15, allowing a sliding seal to be formed between the movable rod 22 and the through hole 15, ensuring that the movable rod 22 will not leak during lifting and lowering adjustment. Furthermore, a suitable sealing cap 17 can be installed at the bottom 14 of the water cup 1. The position of the sealing cap 17 is adapted to the position of the sealing element 16, thus confining the sealing element 16 between the movable rod 22 and the through hole 15.

[0043] A drive component 3 is installed at the bottom 14 of the water cup 1. The drive component 3 can be telescopic and has a telescopically adjustable drive end 31, which can extend and retract. The drive end 31 is connected to the movable rod 22, thereby driving the seal 16 to move and adjust through the drive component 3.

[0044] This embodiment also discloses a control method for a dishwasher, which adopts the energy-saving dishwasher as described in the above embodiment. During the operation of the dishwasher, the sealing plate 2 can be raised and lowered within the water cup 1. The sealing plate 2 is adjusted to a position lower than the upper edge of the water outlet 12 as position one, and the sealing plate 2 is adjusted to a position between the water outlet 12 and the water outlet 13 as position two. The sealing plate 2 can be adjusted between position one and position two when the dishwasher is in operation.

[0045] The working steps of a dishwasher include:

[0046] During the washing stage, the sealing plate 2 is adjusted to position two, allowing external water to enter the dishwasher. Water is supplied by the spray nozzles 7 on the water supply pipe 8, and the heating element 6 heats the water flowing through the water supply pipe 8 to clean the dishes. The sealing plate 2 can disconnect the water supply pipe 8 from the drain pipe 9. When the heating element 6 heats the water between the drain pipe 9 and the water cup 1, the water in the water cup 1 is disconnected from the water in the drain pipe 9, thus preventing the water in the water cup 1 from being disconnected from the water in the drain pipe 9. This reduces the total amount of water used in the heating process, reduces heat waste in the washing water, and thus reduces heating energy consumption.

[0047] During the drainage stage, the sealing plate 2 is adjusted to position 1, and the water outlet 12 is connected to the chamber 101 inside the water cup 1, which allows the water in the dishwasher to be discharged from the drain pipe 9, so that the sewage can be discharged.

[0048] This method utilizes the dishwasher's control system and adjusts the position of the sealing plate 2 to reduce the amount of water used and the heating time during the washing process, thereby reducing the overall washing time, saving users' operating costs, and improving the user's experience of using the dishwasher.

[0049] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
