There are a plurality of air outlets 3 to set up on the other four faces of fan apron 2, and fan apron 2 is hollow bench structure, and fan subassembly is installed in fan apron 2 hollow, under fan apron 2's effect, wraps up fan subassembly, plays the protection to fan subassembly, leads the inside air flow of dish washer simultaneously.

The dish washer comprises an inner container and a double-fan drying system, wherein the side wall 1 of the inner container is formed at the back of the inner container, and a fan assembly is positioned in a cavity of the inner container; the two fan assemblies in the inner container cavity alternately operate.

The two fan assemblies are independently controlled through the main control board, and the two fan assemblies can alternately operate or simultaneously operate or operate singly.

In the actual use process, the fan assembly works to suck the outside air from the air inlet 4 on the front side of the fan cover plate 2, then blow out the outside air along the tangential direction of the rotation of the impeller 6, the heating pipe 5 heats the air on the outer side of the impeller 6, the air blown out by the fan takes away heat, and the air is blown out into the inner cavity of the dish washer through the air outlet 3 of the fan cover plate 2, so that the tableware is dried.

When the tableware in the dish-washing machine is in a full-load or near-full-load state, the working modes of the two fan assemblies are adjusted to be alternative operation modes through the control of a main control board program. When the dish washer enters the drying stage, firstly the left side fan assembly operates, then the corresponding heating pipe 5 of the left side fan assembly operates, and the phenomenon that the heating pipe 5 is dry-burned and heat cannot be timely dissipated is prevented.

After the left fan assembly is operated for a set time, the operation is stopped, and the right fan assembly and the corresponding heating pipe 5 are started to operate. After the right side fan assembly is operated for a set time, the operation is stopped. In a sequential manner, the left fan module and the right fan module alternately operate until the operation is completed to the end time of the drying stage set in the program, and the operation is stopped to complete all operations of the drying stage. The mode that two fan assemblies alternately operate can fully stir the air in the inner cavity of the dish washer, and can blow the heat of the heating pipe to all positions in the inner cavity more uniformly.

When in actual use, when the tableware in the dish washer is in a unilateral state, the tableware of the shelf in the dish washer is not necessarily in a full-load state, the inner cavity of the dish washer can be divided into a unilateral left side or a unilateral right side according to the actual quantity and the placing position of the tableware, the corresponding left side or right side respectively corresponds to the left side fan and the right side fan, and in operation, the left side fan or the right side fan independently operates, so that the drying effect is achieved, and meanwhile, the energy is saved.

Specifically, when the tableware to be cleaned is smaller than half of the full-load state of the dish washing machine or is close to half of the full-load state of the dish washing machine, the tableware to be cleaned is integrally placed on the left side or the right side of the dish washing machine, when the tableware to be cleaned is placed on the left side of the dish washing machine, the fan assembly on the left side in the dish washing machine is controlled by the main control board program to work, and the working fan assembly corresponds to the tableware to be cleaned on the left side of the dish washing machine, so that the drying effect is achieved, and meanwhile, the energy is saved.

When the tableware to be cleaned is placed on the right side of the dish washer, the fan assembly on the right side in the dish washer works under the control of the main control board program, and the working fan assembly corresponds to the tableware to be cleaned on the right side of the dish washer, so that the drying effect is achieved, and meanwhile, the energy is saved.
