[0025] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0026] It should be noted that in the description of this utility model, terms such as "upper," "lower," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0027] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] like Figures 1 to 3 As shown, this utility model provides a dishwasher, characterized in that it includes a fan 10, a heat exchanger 20, an inner liner, and an air guide structure 30. The heat exchanger 20 is connected to the fan 10 and heats the gas input by the fan 10. The heat exchanger 20 is connected to the inner liner and the heated gas flows into the inner liner. The air guide structure 30 is disposed between the heat exchanger 20 and the inner liner and is used to guide the heated gas.

[0029] With this setup, the fan 10 supplies gas to the heat exchanger 20, which heats the gas. The gas then flows to the air guide structure 30, which directs the gas into the inner tank. This allows the heated gas to heat the dishes inside, evaporating any water droplets. The air guide structure also ensures smoother gas flow, minimizing noise. This solution addresses the problem of excessive noise during the drying process in existing dishwashers.

[0030] like Figure 2As shown, in a specific embodiment of this utility model, the air guiding structure 30 includes an air duct 31 and an air guide plate 32. The air guide plate 32 is disposed inside the air duct 31 and is used to guide the gas entering the air duct 31.

[0031] With this setup, the air duct 31 is used to connect the heat exchanger 20 and the inner liner, and the air guide plate 32 guides the gas in the air duct 31, making the gas flow more stable and preventing excessive noise due to changes in the gas flow direction, thus improving the user experience.

[0032] like Figure 2 As shown, it can be understood that the air guiding structure 30 includes an air duct 31 and a baffle 33. The baffle 33 is rotatably disposed in the air duct 31 and is used to isolate the heat exchanger 20 from the gas in the inner liner.

[0033] With this configuration, the baffle 33 is rotatably positioned within the air duct 31. When the gas heated by the heat exchanger 20 flows into the air duct 31, the gas blows the baffle 33, causing it to rotate and allowing the gas within the air duct 31 to flow into the inner liner. When the heat exchanger 20 and the fan 10 are not operating, the baffle 33 separates the heat exchanger 20 from the inner liner, preventing outside air from entering the inner liner along the air duct 31 and contaminating the air inside. Simultaneously, it prevents moisture from the inner liner from entering the fan 10 and the heat exchanger 20, thus preventing moisture from corroding the fan 10 or the heat exchanger 20.

[0034] In practical applications, the baffle 33 can be configured in various ways. For example, a torsion spring can be installed at the connection between the baffle 33 and the air duct 31. When the fan 10 stops working, the baffle 33 will reset under the action of the torsion spring. Alternatively, an elastic element can be installed at the opening and closing position of the baffle 33. When the fan 10 stops working, the elastic element can pull the baffle 33 to reset. Such adjustments and changes to the arrangement of the baffle 33 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0035] Furthermore, it is conceivable that the side wall of the air duct 31 is provided with a limiting protrusion, which is used to limit the rotation angle of the baffle 33 toward the heat exchanger 20.

[0036] With this setting, the rotation angle of the limiting protrusion limiting baffle 33 is such that the baffle 33 can just separate the heat exchanger 20 from the inner tank, avoiding the baffle 33 from rotating too much in the direction of the heat exchanger 20 and colliding with the air duct 31 or the air guide plate 32, causing damage.

[0037] like Figure 3As shown, the air duct 31 is provided with a limiting member 35 at the rotation position of the baffle 33, and a mating member 331 is provided at the rotation position of the baffle 33. The limiting member 35 stops the mating member 331 to limit the rotation angle of the baffle 33 in the direction away from the heat exchanger 20.

[0038] With this setup, when the heated gas blows against the baffle 33, the baffle 33 rotates to a certain angle, and the limiting member 35 and the mating member 331 stop and limit the rotation angle of the baffle 33, so as to prevent the baffle 33 from hitting the side wall of the air duct 31 and generating a lot of noise or causing damage to the air duct 31 after receiving a large impact.

[0039] like Figure 2 As shown, it can be understood that there are multiple air guide plates 32, which are arranged along the air inlet direction and are arc-shaped plates.

[0040] With this design, multiple air guides 32 divide the gas entering the air duct 31 into multiple streams. Each air guide 32 directs the gas flow, resulting in a smoother flow and preventing turbulence that could cause significant noise, thus improving the user experience. The curved shape of the air guides 32 prevents excessive impact on the gas flow; the curve also cushions the impact, further smoothing the gas flow.

[0041] In practical applications, the number of air guide plates 32 can be set differently. For example, two air guide plates 32, three air guide plates 32, or multiple air guide plates 32 can be set. Such adjustments and changes to the number of air guide plates 32 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0042] like Figure 2 As shown, the air guiding structure 30 includes an air duct 31 and air guide strips 34. The air outlet 311 of the air duct 31 is connected to the inner liner. There are multiple air guide strips 34, which are arranged at the air outlet 311. The air guide strips 34 are inclined relative to the flow direction of the gas in the air duct 31.

[0043] With this design, the air guide strip 34 is tilted relative to the direction of gas flow, preventing the gas from blowing directly onto the tableware when entering the inner liner. This avoids damage or burns to the tableware caused by excessively high temperatures from the heated gas blowing directly onto it. The air guide strip 34 also makes the flow of heated gas into the inner liner smoother, preventing excessive impact from the heated gas blowing directly onto the tableware and generating loud noise.

[0044] Furthermore, it is conceivable that the dishwasher also includes a condenser coil, which is connected to the inner tank and is used to discharge condensate and gas from the inner tank.

[0045] With this setup, the condenser tube is connected to the atmosphere. After the gas heated by the heat exchanger 20 enters the inner liner, it evaporates the water droplets on the tableware into water vapor. The hot gas carrying the water vapor enters the condenser tube, where the temperature is lower than that inside the inner liner. The water vapor condenses into condensate inside the condenser tube and is then discharged. The heated gas is then discharged from the condenser tube into the outside air.

[0046] Furthermore, the dishwasher also includes a breather, one end of which is connected to the inner tub and the other end of which is connected to the condenser pipe. The breather is used to deliver the gas in the inner tub to the condenser pipe.

[0047] This design allows the respirator to regulate the pressure difference between the inner liner and the outside environment, preventing damage caused by excessive pressure inside the liner. The respirator vents the gas inside the liner into the condenser tube to release the gas into the outside atmosphere.

[0048] like Figure 1 As shown, the dishwasher also includes a first bracket 41 and a housing. One end of the first bracket 41 is connected to the housing, and the other end of the first bracket 41 is used to fix the fan 10.

[0049] With this setup, one end of the first bracket 41 is connected to the housing, and the other end is used to fix the fan 10 on the housing. The fan 10 is fixedly connected to the heat exchanger 20, so that the fan 10 and the heat exchanger 20 can deliver hot air into the inner liner to remove water droplets from the tableware.

[0050] In practical applications, the first bracket 41 has a fixing ear 411 at one end near the housing. The fixing ear 411 can be set on both sides of the first bracket 41. Those skilled in the art can select the setting position of the fixing ear 411 according to the actual application of the dishwasher.

[0051] like Figure 1 As shown, the dishwasher also includes a second bracket 42, one end of which is connected to the first bracket 41, and the other end of which is connected to the fan 10.

[0052] With this setup, the second bracket 42 secures the fan 10 to one end of the first bracket 41, thereby fixing the fan 10 to the dishwasher housing.

[0053] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
