[0020] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.
[0021] See attached Figure 1-4The present application provides a ventilation and drying system for a dishwasher, which includes an inner tank 1, an air inlet shell 2 and an air outlet shell 3. The air inlet shell and the air outlet shell are arranged on the outside of the inner tank. An air inlet fan 4 and a heating element 5 are provided on the air inlet shell. The heating element can specifically use a PTC heating element. The ventilation heating element heats the air input into the inner tank, increases the temperature of the inner tank, and accelerates the evaporation of moisture in the inner tank. The air outlet end of the air inlet shell is connected to the inner tank, and an air outlet fan 6 is provided on the air outlet shell 3. The air inlet end of the air outlet shell is connected to the inner tank 1. Under the action of the air inlet fan and the air outlet fan, the internal air circulation of the inner tank is realized. The output end of the air outlet shell is connected to an air distribution shell 8 through an air pipe 7. The air distribution shell is provided with an exhaust surface 9, and a plurality of air outlet holes 10 are distributed on the exhaust surface. By providing a plurality of air outlet holes, the area of the air outlet can be increased, and the air outlet pressure can be reduced at the same time, so as to avoid concentrated air outlet to form condensed water.
[0022] See attached Figure 5-6 The top, back and front surfaces of the gas separation shell 8 are all exhaust surfaces 9, which fully utilize the positions of the top, back and front surfaces of the gas separation shell to set the air outlet holes and increase the air outlet area.
[0023] A water tank 81 is formed at the inner bottom of the air separation shell 8, and a drainage notch 82 is provided on the side wall of the air separation shell. The horizontal height of the drainage notch is lower than the connecting port 83 connecting the air separation shell and the air pipe. The water tank can temporarily collect condensed water generated at the end of the air duct, the air pipe and the air outlet in the early stage of drying of the dishwasher, and evaporate it through continuous ventilation in the later stage of drying.
[0024] The output end of the air outlet shell 3 is provided with two air pipes 7 connected to the air distribution shell 8. Correspondingly, the air distribution shell is also provided with two interfaces connected to the air distribution shell. The air is exhausted to the air distribution shell through the two air pipes, so that the air intake of the air distribution shell is more uniform and the air pressure of each air outlet tends to be uniform.
[0025] The air separation shell 8 is arranged at the outer bottom of the inner tank 1 and is located behind the skirting 11 of the dishwasher. The air discharged from the air separation shell is discharged through the gap between the skirting and the door body.
[0026] There are multiple condensation ribs 12 distributed along the air duct inside the air outlet shell 3. The condensation ribs can increase the contact area with the air and produce condensed water. The condensation ribs are arranged at an angle to facilitate water conduction. Water receiving ribs 13 are also provided in the air outlet shell. The water receiving ribs and the inner wall of the air outlet shell form a water storage area 14. The water storage area is connected to the inner tank 1. The water receiving ribs can collect the condensed water and return it to the inner tank.
[0027] Specifically, a respirator 15 is provided on the outside of the inner liner 1. The respirator has a vent 16 connected to the inner liner 1. The air inlet end of the air outlet housing 3 is connected to the respirator 15 to achieve communication with the inner liner. By using the air outlet housing and the respirator to guide air, it is possible to avoid the need for additional ventilation holes in the inner liner. Furthermore, the water outlet of the water storage area 14 is connected to a return pipe 17, which is connected to the respirator 15 to achieve communication with the inner liner. Condensed water flows back into the inner liner through the respirator.
[0028] The above description is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the content disclosed in the present invention should be included in the protection scope recorded in the claims.
