[0029] The novel water pump of the embodiment of the present invention comprises a cylinder 1, a first partition 2, a second partition 3, a first water inlet pipe 4, a first water outlet pipe 5, a first air inlet pipe 6, a first air outlet pipe 7, a water inlet solenoid valve 8, a water outlet solenoid valve 9, an air inlet solenoid valve 10 and a water outlet solenoid valve 11. The cylinder 1 comprises a cylinder wall 111 and a first side wall 112 and a second side wall 113 which are sealed and connected to the cylinder wall 111. The first partition 2 passes through the central axis of the cylinder 1 and is connected to the inner wall of the cylinder 1 by rotating around the central axis. The second partition 3 passes through the central axis of the cylinder 1, intersects the first partition 2 perpendicularly and is fixed to the inner wall of the cylinder 1. The first partition 2 and the second partition 3 divide the cavity of the cylinder 1 into a first chamber 114, a second chamber 115, a third chamber 116 and a fourth chamber 117. The first water inlet pipe 4 is fixedly connected to the first side wall 112 and extends into the first chamber 114, and the first water outlet pipe 5 is fixedly connected to the second side wall 113 and extends into the first chamber 114.

[0033] In a preferred embodiment of the present invention, the novel water pump further comprises a second water inlet pipe 13 and a second water outlet pipe 14. The second water inlet pipe 13 is fixedly connected to the first side wall 112 and extends into the third chamber 116.

The first water inlet pipe 4 and the second water inlet pipe 13 are respectively connected to the main water inlet pipe, and the first water outlet pipe 5 and the second water outlet pipe 14 are respectively connected to the main water outlet pipe.

[0034] like Figures 1 to 3 As shown, the novel water pump may include a second water inlet pipe 13 and a second water outlet pipe 14 to make fuller use of the four chambers. The main water inlet pipe and the main water outlet pipe control the inlet and outlet of water through the water inlet solenoid valve 8 and the water outlet solenoid valve 9 respectively.

[0035] Preferably, there may be multiple water inlet pipes and multiple water outlet pipes.

[0036] In a preferred embodiment of the present invention, the novel water pump further comprises a second air inlet pipe 15 and a second air outlet pipe 16. The second air inlet pipe 15 is fixedly connected to the first side wall 112 and extends into the fourth chamber 117. The second air outlet pipe 16 is fixedly connected to the second side wall 113 and extends into the fourth chamber 117. The first air inlet pipe 6 and the second air inlet pipe 15 are respectively connected to the main air inlet pipe, and the first air outlet pipe 7 and the second air outlet pipe 16 are respectively connected to the main air outlet pipe.

[0037] like Figures 1 to 3 As shown, the novel water pump may include two air inlet pipes 15 and a second air outlet pipe 16 to make fuller use of the four chambers. The main water inlet pipe and the main water outlet pipe control the inlet and outlet of air through the air inlet solenoid valve 10 and the air outlet solenoid valve 11 respectively.

[0038] Preferably, there may be multiple air inlet pipes and multiple air outlet pipes.

[0039] The new water pump of the present invention adopts a first partition plate 2 and a second partition plate 3 to separate the cylindrical body 1 of the water pump into four chambers, namely, a first chamber 114, a second chamber 115, a third chamber 116 and a fourth chamber 117. The first water inlet pipe 4 and the first water outlet pipe 5 are located in the first chamber 114; the first air inlet pipe 6 and the first air outlet pipe 7 are located in the second chamber 115; the second water inlet pipe 13 and the second water outlet pipe 14 are located in the third chamber 116; the second air inlet pipe 15 and the second air outlet pipe 16 are located in the fourth chamber 117.

[0040] 8. Under the control of the water outlet solenoid valve 9, the air inlet solenoid valve 10 and the air outlet solenoid valve 11, air and water are mixed from the main water outlet pipe and the main air outlet pipe, and then alternately introduced into the cleaning nozzle 18. Relying on the high-pressure release process of compressed air, sections of water columns are ejected, which increases the speed of the sprayed water columns and enhances the cleaning effect.

[0041] A dishwasher according to an embodiment of the present invention comprises the aforementioned novel water pump, a delivery pipe 17 and a cleaning nozzle 18. The cleaning nozzle 18 has a spray hole. One end of the delivery pipe 17 is respectively connected to the main water outlet pipe and the main air outlet pipe, and the other end is connected to the cleaning nozzle 18 so that the main water outlet pipe and the main air outlet pipe are connected to the cleaning nozzle 18. The cleaning nozzle 18 has the same thickness as the main water outlet pipe and the main air outlet pipe. The cleaning nozzle 18 is evenly distributed with spray holes.

[0042] The thickness of the cleaning nozzle 18 is consistent with that of the main water outlet pipe and the main air outlet pipe, in order to maintain the alternating placement of air and water flow, and to prevent the water flow and air flow from mixing prematurely due to the thick spray arm, which affects the spraying effect. Through the alternating inflow of air and water flow, the high-pressure release process of compressed air can be relied on to make sections of water columns spray out, which increases the speed of the sprayed water column and enhances the cleaning effect. A high dishwasher cleaning rate increases the competitiveness of the enterprise and improves the user experience.
