When the heating module and the fan 13 work, hot air is generated and enters the drying area 12 through the air supply outlet 131 and the hot air inlet 121. Because the fan 13 is working, the air inlet of the fan will form a low-pressure area, so that the hot air leaves through the hot air outlet 122 after the appliance to be dried is dried in the drying area 12, but enters the fan 13 again under the action of the atmospheric pressure and the guiding action of the first air duct 14, so that the hot air is heated again and the drying area 12 is dried. The heating module and the fan 13 heat the hot air entering from the first air duct 14 or directly utilize the hot air to perform drying treatment, so that the drying efficiency can be improved, and the drying energy consumption can be reduced.

Specifically, the heating module is arranged in the fan 13, so that the effect of hot air generated by the fan can be realized. As shown in fig. 6, the heating module may be disposed at the air supply outlet 131 of the blower 13, and the air supply outlet 131 is communicated with the hot air inlet 121 of the drying zone 12, so that hot air is heated by the heating module at the air supply outlet 131 and then enters the drying zone 12, thereby implementing the drying treatment of the appliance to be dried in the drying zone 12; the heating module can be arranged at an air inlet of the fan 13, a low-pressure area is formed when the fan 13 works, hot air enters the fan 13 through the heating module under the action of atmospheric pressure, and the heated hot air enters the drying area 12 under the pushing of the fan 13, so that the drying treatment of the appliance to be dried in the drying area 12 is realized.

Specifically, the first air duct 14 may guide the air after the drying process to enter the blower 13 again for recycling. As shown in fig. 6, the fan 13 is disposed in the backflow hood 15, the first air duct 14 communicates the drying region 12 and the backflow hood 15, since the backflow hood 15 communicates with the outside only through the hot air outlet 121 and the first air duct 14, hot air can be accumulated in the backflow hood 15, and heating and drying processes are performed again under the push of the fan 13, since the backflow hood 15 communicates with the first air duct 14, hot air can be accumulated in the backflow hood 15, and recycling of hot air can be achieved; as shown in fig. 7, arrows in fig. 7 are hot air circulation paths, the first air duct 14 communicates the hot air outlet 122 of the drying zone 12 with the air supply opening 131 of the fan 13, and because the flow rate at the air supply opening 131 is fast and the pressure is small, a siphon effect is easily formed, hot air is sucked into the fan 13 and enters the air supply opening 131 under the action of the siphon effect, and is heated again by the heating module and is sent into the drying zone 12 through the hot air inlet 121, so that the hot air is recycled, and compared with directly generating hot air, the hot air with a certain heat is recycled, so that the drying efficiency can be improved, and the drying energy consumption can be reduced; taking a centrifugal fan as an example, as shown in fig. 8, the first air duct 14 may further be connected to a volute 132 of the fan 13, so that on one hand, the air intake of the fan 13 may be increased, and on the other hand, hot air may be recovered, thereby increasing the drying efficiency and reducing the drying energy consumption.

Specifically, as shown in fig. 6, 7 and 8, the arrows in the drawings are hot air circulation paths, and the heating module includes the heating pipes 11, so that the air heating effect can be improved. The projection directions of fig. 6, 7 and 8 are all the same as the axial direction of the heat generating tube 11. The heating tube 11 has a small windward area, and taking the cylindrical heating tube 11 as an example, the windward area is only the product of the axial length and the diameter of the heating tube 11, so that the heating tube 11 is subjected to a small pressure, and the heating tube 11 can be prevented from being blown and bent by the fan 13.

Further, the hot air outlet 122 is provided with a flow guiding cover 18, and the top of the flow guiding cover 18 is communicated with the first air duct 14.

It can be understood that the hot air outlet 122 is used as the only way for the hot air in the drying system to leave the drying system, the air guide sleeve 18 is arranged at the hot air outlet 122, and the hot air is guided into the first air duct 14 communicated with the air guide sleeve 18 for recycling, so that the heating efficiency of the heating module and the drying efficiency of the drying area are improved, meanwhile, the energy consumption of the drying system can be reduced, and the situation that the heat energy of the drying system escapes from the hot air outlet 121 is also reduced.

Specifically, as shown in fig. 1, the washing system comprises a pre-washing system 4, a main washing system 3 and a rinsing system 2, the three systems can be increased or decreased according to actual conditions, and the three systems are matched with the drying system 1 to realize the dish washing function of the dish washing machine. Taking the inlet 123 of the drying system 1 and the rinsing system 2 as an example, the rinsed appliance enters the drying system 1 through the inlet 123 under the action of the conveyor belt 5, the fan 13 and the heating module of the drying system 1 generate hot air, the hot air is blown to the appliance to be dried, the dried hot air leaves from the hot air outlet 122 of the drying area 12, the hot air with moisture sinks, and the hot air not participating in drying is guided back to the fan 13 by the first air duct 14 under the action of atmospheric pressure, so that the air is recycled, the drying efficiency is improved, and the drying energy consumption is reduced.

Further, as shown in fig. 2 and 4, the fan 13 includes a fan cover 16, the fan cover 16 is a hollow quadrangular frustum pyramid structure with an open top and a open bottom, the bottom of the fan cover 16 is connected to an air supply outlet 131 of the fan 13, and the fan cover 16 extends into the drying zone 12 of the drying system 1.

It can be understood that the lower bottom surface of the quadrangular frustum shaped wind cover 16 is connected with the air supply opening 131 of the fan 13, so that the air outlet cross section of the fan 13 is reduced, and as can be seen from the continuity equation, the flow rates of the upper bottom surface and the lower bottom surface of the wind cover 16 should be the same, but the air outlet cross section of the upper bottom surface is reduced, and the corresponding flow rate should be higher than that of the lower bottom surface, so that the wind cover 16 can increase the flow rate of hot air, increase the flow rate of air on the surface of the appliance to be dried, and accelerate the drying efficiency.

Further, an inverted V-shaped deflector 17 is disposed in the fan housing 16.

As shown in fig. 2 and 3, the air deflector 17 is disposed in the fan housing 16, on one hand, the air outlet cross section is reduced, the flow velocity of air is increased, the flow velocity of hot air on the surface of the appliance to be dried is increased, and the drying efficiency is increased; on the other hand, the guide plate 17 improves the structural strength of the fan housing 16, and avoids the noise generated by the vibration of the fan housing 16 due to the overhigh flow velocity of the hot air.

Further, as shown in fig. 1, 3 and 4, the hot air inlet 121 is provided at the top of the drying zone 12, and the fan 13 is provided at the top of the drying zone 12.

It can be understood that, when the fan arranged at the top of the drying area 12 works, hot air can enter the drying area 12 under the action of gravity, so that the flow rate of the hot air can be improved, and the drying efficiency is further improved.

Optionally, the number of baffles 17 is 3. The specific number of the guide plates can be flexibly set according to actual application occasions, and the specific number is not limited in the embodiment.

It can be understood that 3 air deflectors 17 make the air blown out by the fan 13 relatively concentrated, as shown in fig. 3, and improve the drying efficiency.

Optionally, wind screens are arranged at the hot air outlet 122 and the hot air inlet 123. It can be understood that the arrangement of the wind blocking curtain can reduce the hot wind from the hot wind outlet 122 and the hot wind inlet 123, and improve the drying efficiency of the drying system.

Specifically, the drying system 1 includes a second air duct 20, the second air duct 20 is disposed in a side wall of the drying region 12, and the second air duct 20 communicates the drying region 12 and the return hood 15.

It can be understood that fans of different powers require different sizes of air inlets, and that, in this embodiment, as the only air intake way of the return hood 15, the air intake is mainly embodied as the sectional area of the first air duct 14, but due to the structural characteristics of the air guide hood 18 itself, if the first air path 14 is to be hidden in the upper portion of the air guide sleeve 18, the cross-sectional area of the first air path 14 cannot be too large, therefore, the size of the air inlet of the fan 13 is limited, the air inlet resistance of the fan 13 is increased by the too small air inlet, the normal work of the fan 13 is influenced, as shown in fig. 9, the second air duct 20 provides other ways for hot air to flow back to the fan 13, and indirectly increases the size of the air inlet of the fan 13, which is beneficial to reducing the air inlet resistance, and on the other hand, the second air duct 20 is arranged in the side wall, which is also beneficial to hiding the second air duct 20, and improves the overall aesthetic effect of the dishwasher.
