The stop frame 511 limits the air flow in the first air channel to pass through only the air passing opening 5111 formed by the closure of the stop frame 511, and the backflow preventing member 54 can correspondingly open or close the air passing opening 5111, so that the backflow preventing member 54 can better prevent the air in the first air channel from flowing back to the heating member 53.

Referring to fig. 9, in an embodiment of the present invention, the backflow preventing member 54 includes two opposite side walls and a baffle plate connected between the two side walls, the baffle plate encloses the two side walls to form an air accommodating groove, one end of the baffle plate or the two side walls is rotatably connected to the stop frame 511, and the baffle plate and the two side walls are movably abutted against the stop frame 511 at edges.

When air flows from the heating element 53 to the air inlet 111, the air can gather in the air accommodating groove, so that the force of the air flow acting on the backflow preventing element 54 is more concentrated, and the backflow preventing element 54 is easy to open along the direction from the heating element 53 to the air inlet 111.

Further, the volume of the air accommodating groove is gradually increased from one end of the rotating connection to the other end, the larger the volume of the air accommodating groove is, the larger the acting force of the air flow on the inner wall of the air accommodating groove is, according to the lever principle, the acting force of the air flow on the end part of the backflow preventing piece 54 far away from the rotating connection is large, the backflow preventing piece 54 is easier to rotate along the direction far away from the heating piece 53, so that the air passing port 5111 is opened, and the air inlet assembly is convenient to guide hot air into the first groove body 10.

Referring to fig. 9, in an embodiment of the present invention, the air intake assembly 50 further includes a sterilization member 55, the sterilization member 55 is located in the first air duct, the fan 52 drives the external air into the first air duct, and the external air sequentially passes through the heating member 53, the backflow preventing member 54 and the sterilization member 55 and enters the first tank body 10 through the air inlet 111.

Air led in by the air inlet assembly 50 is heated by the heating piece 53 to form hot air with higher temperature, and then the hot air is further sterilized by the sterilizing piece 55, so that bacteria in the air can be killed by the sterilizing piece 55, the effect of purifying the air is achieved, the hot air led in the first tank body 10 is cleaner, and tableware in the first tank body 10 is more thoroughly cleaned.

Referring to fig. 1, 8 and 9, in an embodiment of the present invention, the air intake assembly 50 is further provided with a second overflow port 56 communicating with the first air duct, the second overflow port 56 is located downstream of the heating element 53, and the height of the second overflow port 56 in the longitudinal direction is higher than the highest water level in the first tank 10.

Once the liquid in the first tank 10 enters the first air duct through the air inlet 111, the liquid will flow out through the second overflow port 56 under the guidance of the first air duct, and will not further flow to the heating element 53, so as to damage the heating element 53. Since the height of the second overflow port 56 is higher than the highest water level in the first tank 10, the liquid entering the first air duct will not pass over the second overflow port 56 as long as the liquid in the first tank 10 is not higher than the highest water level according to the principle of the communicating vessel, thereby protecting the heating element 53 in the first air duct.

The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
