Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This embodiment discloses an internal water system for a dishwasher, which supplies water to the inside of the dishwasher's inner tub for internal spraying; see reference. Figures 1-5 As shown, the internal water circuit of the dishwasher in this embodiment includes a water inlet pipe 20 and a sprayer 30. Both the water inlet pipe 20 and the sprayer 30 are located inside the dishwasher tub. The water inlet pipe 20 is divided into two paths, including a first water inlet pipe 21 and a second water inlet pipe 22. The first water inlet pipe 21 is installed on the base 10 of the dishwasher tub, and the second water inlet pipe 22 is fixedly installed on the side wall of the dishwasher tub, located above the first water inlet pipe 21 and extending upward.

[0025] The sprayer 30 is divided into three layers, including an upper sprayer 31, a middle sprayer 32, and a lower sprayer 33. The upper sprayer 31, the middle sprayer 32, and the lower sprayer 33 are arranged from top to bottom. The upper sprayer 31 is installed on the first water inlet pipe 21, and the middle sprayer 32 and the lower sprayer 33 are installed on the second water inlet pipe 22.

[0026] There is one upper sprayer 31, located at the top center of the dishwasher inner tub; there are two middle sprayers 32 and two lower sprayers 33. The two middle sprayers 32 are arranged roughly side by side, and the two lower sprayers 33 are also arranged roughly side by side, for a total of five sprayers 30 spraying the dishwasher inner tub together.

[0027] To increase the coverage area of ​​the spray, the two lower sprayers 33 can be slightly staggered vertically, and the length of the spray arm of the lower sprayer 33 can be appropriately extended, thereby improving the coverage rate of the spray. (Refer to...) Figure 4 As shown.

[0028] Reference Figure 2 As shown, a mounting groove 11 is provided on the upper side of the base 10. The mounting groove 11 is adapted to the shape of the first water inlet pipe 21, and the first water inlet pipe 21 is at least partially embedded in the mounting groove 11. By embedding the first water inlet pipe 21, the bottom of the dishwasher can be kept basically flat.

[0029] Reference Figure 3 As shown, the bottom of the first water inlet pipe 21 is open, and the mounting groove 11 can seal and cover the bottom of the first water inlet pipe 21. A seal can be installed at the connection to maintain the seal.

[0030] The base 10 has a first water outlet 12 and a second water outlet 13. The first water outlet 12 is connected to the second water inlet pipe 22, and the second water outlet 13 is also connected to the second water inlet pipe 22. The first water outlet 12 and the second water outlet 13 can form two water supply channels, thereby enabling water to be supplied to the first water inlet pipe 21 and the second water inlet pipe 22 respectively.

[0031] Reference Figure 2 , Figure 3 , Figure 5 As shown, the internal water circuit of the dishwasher in this embodiment also includes a water distributor 40. The water distributor 40 is fixedly installed on the lower part of the base 10. The water distributor 40 is connected to the first water outlet 12 and the second water outlet. By switching the state of the water distributor 40, the on / off control of the first water outlet 12 and the second water outlet 13 can be realized.

[0032] The water distributor 40 has three states: In the first state, both the first and second water outlets 12 and 13 are open, and the upper sprayer 31, middle sprayer 32, and lower sprayer 33 spray simultaneously; in the second state, the first water outlet 12 is open, the second water outlet 13 is closed, the upper and middle sprayers 31 and 32 spray, and the lower sprayer 33 stops spraying; in the third state, the first water outlet 12 is closed, the second water outlet 13 is open, the lower sprayer 33 sprays, and the upper and middle sprayers 31 and 32 stop spraying. By switching the water distributor 40, the states of the three sprayers 30 can be switched, thus achieving different spray washing states.

[0033] The water distributor 40 is specifically a valve structure, which can enable the first water outlet 12 and the second water outlet 13 to be opened together or one of them to be opened.

[0034] In this embodiment, the water distributor 40 includes a main body and a cover 14, which together form a complete water distributor 40. The cover 14 is integrally formed with the base 10. A first water outlet 12 and a second water outlet are located on the cover 14, extending upwards to the upper side of the base 10 and downwards to the inner cavity of the water distributor 40. A valve plate 42 is rotatably connected to the water distributor 40 and can be driven to rotate by a motor. The valve plate 42 has four control positions arranged in a circumferential array, three of which have through holes 421, while the other is closed.

[0035] By rotating the regulating valve plate 42, when two of the through holes 421 of the valve plate 42 are connected to the first water outlet 12 and the second water outlet 13, the two water inlet pipes 20 can be connected together, and the three spray layers 30 can spray simultaneously. When the closed position of the valve plate 42 is opposite to the first water outlet 12 and one of the through holes 421 of the valve plate 42 is opposite to the second water outlet 13, the first water inlet pipe 21 can be connected and the second water inlet pipe 22 can be closed, allowing the upper sprayer 31 and the middle sprayer 32 to spray while the lower sprayer 33 is paused. When the closed position of the valve plate 42 is opposite to the second water outlet 13 and one of the through holes 421 of the valve plate 42 is opposite to the first water outlet 12, the second water inlet pipe 22 can be connected and the first water inlet pipe 21 can be closed, allowing the lower sprayer 33 to spray while the upper sprayer 31 and the middle sprayer 32 are paused.

[0036] The base 10 is integrally formed with a water cup 15, and the water distributor 40 has a water inlet hole 41 on its outer periphery. The water inlet hole 41 is connected to the inner cavity of the water distributor 40 and is used to supply water to the water distributor 40.

[0037] Reference Figure 5 As shown, the internal water circuit of the dishwasher in this embodiment also includes a washing pump 50, a first water pipe 51, and a second water pipe 52.
