[0019] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.
[0020] The utility model discloses a device for discharging residual water from a dishwasher cup. Figures 1 to 3 As shown, it includes a water cup 1, a respirator 2 and a residual water pump 3. The respirator 2 is provided with an inverted U-shaped channel 20, a first channel 21 and a second channel 22. The bottom of the respirator 2 is provided with an inner drainage inlet port 23, a water outlet port 24 and a residual water port 25. The two ends of the inverted U-shaped channel 20 are respectively connected to the inner drainage inlet port 23 and the water outlet port 24. One end of the first channel 21 is connected to the inverted U-shaped channel 20, and the other end of the first channel 21 is connected to the top of the respirator 2. The second channel 22 extends in the direction of the top of the respirator 2, one end of the second channel 22 is connected with the residual water port 25, the other end of the second channel 22 extends toward the top of the respirator 2 and is unidirectionally connected to the first channel 21, the internal drainage inlet respirator port 23 is connected to the water cup 1 through the internal drainage pipe 4, the water outlet port 24 is connected with the external drainage pipe 5, the residual water pump 3 is serially connected to the residual water pipe 6 between the residual water port 25 and the bottom of the water cup 1, and the residual water pump 3 is used to pump water from the water cup 1.
[0021] In the above structure, when the dishwasher is finished working, the drain pump is started to discharge most of the water in the water cup 1 through the inner drain pipe 4, the inverted U-shaped channel 20 and the outer drain pipe 5. For a small amount of residual water in the water cup 1, the residual water pump 3 can be started after the drain pump stops working. The residual water pump 3 extracts the residual water at the bottom of the water cup 1 and discharges it into the first channel 21 through the residual water pipe 6 and the second channel 22. Then, the residual water flows from the first channel 21 to the water outlet port 24, thereby realizing the discharge function of the residual water. Compared with the prior art, the present invention adds a discharge passage for residual water on the basis of the main drain pipe. , it can further discharge the residual water after the dishwasher drains normally, so that the water cup can be dried quickly to avoid the breeding of bacteria and the generation of odor; at the same time, the utility model sets a first channel 21 and a second channel 22 in the respirator 2, and the first channel 21 and the second channel 22 can be injection molded together with the respirator 2, so the manufacturing process is simpler and the application cost is lower; in addition, because the first channel 21 and the second channel 22 both extend toward the upper end of the respirator 2, it can effectively prevent the water in the inverted U-shaped channel 20 from flowing back toward the residual water pump 3, so that the drainage and residual water removal processes do not interfere with each other, thereby optimizing the drainage performance of the dishwasher.
[0022] In order to further prevent water from flowing back into the water cup 1 during drainage, in the present embodiment, the residual water pump 3 is a one-way water pump with a check valve.
[0023] Combination Figures 3 to 5 As shown, as a preferred embodiment, a drainage cavity 10 is provided at the bottom of the water cup 1, and a residual water pipe head 11 extending laterally is provided at the bottom of the drainage cavity 10, and the residual water pipe 6 is plugged into the residual water pipe head 11. In this embodiment, the residual water pipe head 11 is preferably arranged horizontally at the bottom of the drainage cavity 10, so that the residual water in the drainage cavity 10 can flow into the residual water pipe head 11 as much as possible, thereby draining the residual water.
[0024] In this embodiment, an upper passage 12 and a lower passage 13 are provided in the drainage cavity 10 , the upper passage 12 is connected to the water cup 1 , the lower passage 13 is connected to the residual water pipe head 11 , and the opening of the lower passage 13 is covered with a filter 14 .
[0025] In the above structure, the upper passage 12 is used for normal drainage, and the lower passage 13 is used for draining residual water. Since the upper passage 12 is located above the lower passage 13, even if there is residual water in the water cup 1, it will naturally flow into the lower passage 13 and then be drained by the residual water pipe head 11. On this basis, the opening of the lower passage 13 is covered with a filter 14 in this embodiment. Under the shielding of the filter 14, dust, small insects, etc. can be prevented from entering the water cup.
[0026] In order to prevent water from flowing back into the second channel 22 due to the siphon effect, a drainage siphon check valve is provided in this embodiment. Figure 6 In this embodiment, a partition plate 26 is provided between the second channel 22 and the first channel 21, and a drainage siphon port 27 is provided on the partition plate 26. A first one-way valve plate 28 is fixed in the first channel 21, and the first one-way valve plate 28 covers the drainage siphon port 27. One end of the first one-way valve plate 28 is fixed in the first channel 21, and the other end of the first one-way valve plate 28 droops naturally. When reverse pressure is generated in the first channel 21, the first one-way valve plate 28 tightly covers the drainage siphon port 27, thereby playing an anti-siphon role.
[0027] See also Figure 7 In this embodiment, a second one-way valve 29 is provided at the connection between the inverted U-shaped channel 20 and the inner water discharge inlet port 23, and the second one-way valve 29 covers the inner water discharge inlet port 23. The second one-way valve 29 mainly plays a check function to prevent the residual water in the respirator 2 from flowing back into the water cup 1.
[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
