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.

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 7 to heat the air flowing through the air intake channel 7, thereby achieving the rapid drying of the internal environment of the washing machine.
