[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] like Figures 1 to 6 As shown, the dishwasher of this preferred embodiment includes a housing 1 and a condenser A. The housing 1 has a washing cavity inside, and the housing 1 is provided with an air outlet 11 and an air return port 12 which are connected to the washing cavity.

[0033] Condenser A includes a box body 2, a condensation structure and a pumping structure 3. The box body 2 has an inner cavity 21. The box body 2 is provided with an air inlet 22, an air outlet 23 and a drain port 24 which are all connected to the inner cavity 21. The air outlet 11 is connected to the air inlet 22 on the box body 2, and the return air port 12 is connected to the air outlet 23 on the box body 2. The condensation structure is arranged in the inner cavity 21 of the box body 2 and is located on the air flow path, and is used to condense the air flow.

[0034] In this way, the airflow flowing out of the air outlet 11 will continue to flow after being condensed by the condensation structure to dry the tableware; and the convective gas flowing into the washing chamber always comes from the inside of the washing chamber, without the introduction of external gas, and will not cause secondary pollution to the tableware.

[0035] An air inlet 22 is provided on the first side wall of the box body 2, an air outlet 23 is provided on the second side wall of the box body 2, a liquid discharge port 24 is located on the bottom wall of the box body 2, and the first side wall and the second side wall are arranged opposite to each other.

[0036] The condensation structure includes a liquid collecting area 25 that can store cooling water. A water inlet 26 for injecting water into the liquid collecting area 25 is provided on the top wall of the box body 2. A plurality of air flow channels 27 are arranged in sequence in the vertical direction in the box body 2. Each of the air flow channels 27 extends laterally. One end of the air flow channel 27 faces the first side wall, and the other end of the air flow channel 27 faces the second side wall of the box body 2. The air flow channel 27 passes through the liquid collecting area 25. In this way, when the air flow flows from the air flow channel 27, it will be quickly dissipated and condensed by the wall surface of the air flow channel 27 and the cooling water in the liquid collecting area 25, and the condensation effect is good.

[0037] The box body 2 is provided with a water storage area 28 for storing condensed water, the water storage area 28 is connected to the drain port 24, and the box body 2 is provided with a pumping structure 3 that can pump water toward the drain port 24 when the liquid level in the water storage area 28 is higher than the set liquid level. The condensation structure is arranged close to the first side wall, and the pumping structure 3 is arranged close to the second side wall.

[0038] The pumping structure 3 is an inverted U-shaped water flow channel. The area between the water flow channel and the first side wall and below the horizontal line where the highest point of the water flow channel is located is the water storage area 28, that is, the water storage area 28 and the pumping structure 3 are arranged side by side in the horizontal direction.

[0039] The water inlet end 31 of the water flow channel is connected to the water storage area 28, and the water outlet end 32 of the water flow channel is connected to the drain port 24. The horizontal line where the highest point of the water flow channel is located is the set liquid level line of the water storage area 28, and the set liquid level line is called the A liquid level line. The structure of the pumping structure 3 of this embodiment is simple. When the liquid level in the water storage area 28 is higher than the set liquid level line, a siphon effect will be generated, and the water will automatically flow from the water flow channel to the drain port 24 for discharge.

[0040] There is a distance L between the water inlet end 31 of the water flow channel and the bottom wall surface of the inner cavity 21. The horizontal line where the water inlet end 31 of the water flow channel is located is called the B liquid level line. In this way, when the liquid level line of the water storage area 28 reaches the B liquid line, the liquid level will not continue to drop, forming a water seal, and the airflow will not enter the water flow channel, and all will be discharged from the air outlet 23.

[0041] In addition, the bottom wall surface of the water storage area 28 is inclined downward from the first side wall toward the direction where the second side wall is located, so as to facilitate the water flow in the water storage area 28 to flow into the water flow channel.

[0042] In addition, the condensation structure also includes a plurality of vertically extending condensation ribs 4, and the lower end of at least one of the condensation ribs 4 is located in the water storage area 28. The condensation ribs 4 will be cooled by the condensation water to ensure the condensation effect of the condensation structure.

[0043] The drain port 24 is connected to a drain pipe 5 , which can be communicated with a sewer pipe 61 . In addition, a water tank 6 is provided above the box body 1 , and a drain port is provided on the bottom wall of the water tank 6 , which is also communicated with the sewer pipe 61 .

[0044] The working process of the condenser A of this embodiment is as follows:

[0045] When the user uses the dishwasher for the first time, because the condensed water level is lower than the B liquid level line, some gas will enter the water flow channel, enter the sewer pipe 61 from the drain port 24 and then enter the sink for discharge. When more and more condensed water is formed, the liquid level of the water storage area 28 is higher than the B liquid level line. After that, the hot air will completely enter the washing chamber from the air outlet 23. As the dishwasher is used more and more times, when the condensed water level in the water storage area 28 is higher than the A liquid level line, the water flow channel meets the siphon condition at this time. Under the action of siphon, the water in the water storage area 28 enters the drain port 24 through the water flow channel, is discharged into the sewer pipe and finally discharged. As the drainage process proceeds, when the liquid level in the water storage area 28 drops to the B liquid level line, the gas enters the water flow channel to destroy the siphon condition, and the liquid level no longer drops but remains at the B liquid level line. In this way, the condensed water formed in the subsequent condensation process slowly gathers in the water storage area 28, and the automatic drainage process is completed under the action of siphon.
