Example one
As shown in fig. 1 to 4, the air duct structure of the dishwasher according to the present embodiment includes an air intake duct 2, which is communicated with the accommodating chamber 1 of the dishwasher, and is used for supplying air to the accommodating chamber 1 of the dishwasher to dry the accommodating chamber 1; the air exhaust channel 3 is communicated with the accommodating chamber 1 of the dish-washing machine and is used for exhausting the air in the accommodating chamber 1 out of the dish-washing machine, meanwhile, a fan unit 202 is also arranged in the air inlet channel 2, and the fan unit 202 provides air inlet for the accommodating chamber 1; wherein, the air intake channel 2 is provided with a heating unit 201 for heating the air flowing through to form dry hot air flowing into the accommodating chamber 1; the exhaust duct 3 is provided with a regulating assembly 301 for achieving communication or disconnection of the exhaust duct 3 with the accommodation chamber 1.

EXAMPLE III
As shown in fig. 1 to 4, the present embodiment is further limited to the first embodiment or the second embodiment, in the air duct structure of the dishwasher of the present embodiment, the fan unit 202 is a cross-flow fan disposed in the air inlet channel 2, most of the air sources of the present dishwasher use a centrifugal fan and an axial flow fan to provide an air source, such fans have the disadvantages of small air volume, large noise, etc., and have serious influence on the surrounding environment during use, and poor user experience. The blown wind is concentrated and columnar, so that a plurality of the blown wind can be combined for use to form relay type airflow transmission, a cross flow fan is also called a cross flow fan, which is firstly proposed by French engineer Morter (Mortier) in 1892, and an impeller is multi-blade type and long cylindrical and is provided with forward multi-wing blades. When the impeller rotates, airflow enters the blade grids from the opening position of the impeller, passes through the inside of the impeller and is discharged into the volute from the blade grids on the other side to form working airflow. The flow of the air flow in the impeller is complicated, the speed field of the air flow is unstable, and a vortex is also present in the impeller, the center of which is located near the volute tongue. The existence of the vortex enables the output end of the impeller to generate circulating flow, and outside the vortex, an airflow streamline in the impeller is arc-shaped. Thus, the flow velocity at each point on the outer circumference of the impeller is non-uniform, with greater velocity nearer the vortex core and less velocity nearer the volute. The air flow velocity and pressure at the fan outlet are not uniform, so the flow coefficient and pressure coefficient of the fan are averages. The position of the vortex has great influence on the performance of the cross flow fan, the center of the vortex is close to the inner circumference of the impeller and is close to the volute tongue, and the performance of the fan is good; the center of the vortex is far away from the vortex tongue, so that the area of the circulating flow is increased, the efficiency of the fan is reduced, and the unstable degree of the flow is increased, therefore, the cross flow fan provided by the embodiment provides a large amount of drying air sources, and meanwhile, the noise is low during the operation of the cross flow fan, the influence on the surrounding environment of the dish washing machine is reduced, and a more comfortable environment is provided for users.
Example four
As shown in fig. 1 to 4, this embodiment is further limited to any one of the first to third embodiments, in the air duct structure of the dishwasher of this embodiment, the heating surface formed by the heating unit 201 in the air inlet channel 2 at least covers the flow field of the air supplied by the fan unit 202, so as to ensure that the wind energy supplied by the fan unit 202 can be completely heated by the heating unit 201 to form dry wind, which is further supplied into the accommodating chamber 1, further, the heating unit 201 is a PTC heater arranged in the air inlet channel 2, and the PTC heater is also called a PTC heater, and is composed of a PTC ceramic heating element and an aluminum tube. The PTC heating element has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant-temperature and electricity-saving electric heater. The safety device is characterized in that the surface of an electric heating tube heater does not turn red under any application condition on the safety performance, so that potential safety hazards such as scalding and fire hazards are caused. The PTC heating body product adopts the u-shaped corrugated radiating fins, so that the heat dissipation rate is improved, the advantages of adhesion and mechanical type are integrated, various thermal and electrical phenomena of the PTC heating element during working are fully considered, the bonding force is strong, the heat conduction and the heat dissipation performance are excellent, the efficiency is high, and the PTC heating body product is safe and reliable. The PTC heater has the advantages of small thermal resistance and high heat exchange efficiency, and is an automatic constant-temperature and electricity-saving electric heater. The PTC heater has the prominent characteristic of safety performance, namely, when the fan stops due to failure, the PTC heater can automatically and rapidly reduce the power because the PTC heater cannot fully dissipate heat, and the surface temperature of the heater is maintained at about the Curie temperature (generally about 250 ℃), so that the surface of the heater such as an electric heating tube heater cannot be red. Therefore, the present embodiment provides the strip-shaped heating element PTC on the air intake channel 2 to heat the air flowing through the air intake channel 2, thereby achieving the rapid drying of the internal environment of the washing machine.
