Example nine

As shown in fig. 1 to 4, the present embodiment is further limited to the first to eighth embodiments, and the air duct structure of the dishwasher of the present embodiment further includes a fan unit 401, the fan unit 401 is a cross-flow fan disposed in the air inlet channel 4, most of the air sources of the present dishwasher adopt a centrifugal fan and an axial-flow fan to provide air sources, 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.

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 402. The safety device has the outstanding characteristics that in terms of safety performance, the phenomenon of 'red' on the surface of the electric heating tube heater 402 can not be generated under any application condition, 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 402 has the advantages of low thermal resistance and high heat exchange efficiency, and is an automatic constant-temperature and electricity-saving electric heater 402. The safety performance of the heater is characterized in that when the fan stops due to failure, the power of the PTC heater 402 can automatically and rapidly decrease because the PTC heater 402 cannot fully dissipate heat, and the surface temperature of the heater 402 is maintained at about the Curie temperature (generally about 250 ℃), so that the surface of the heater 402 such as an electric heating tube heater 402 cannot be red. Therefore, the present embodiment is provided with the strip-shaped heating element PTC on the air intake channel 4, which heats the air flowing through the air intake channel 4, and realizes the rapid drying of the internal environment of the washing machine.

Thus, the claims following the detailed description are hereby expressly incorporated into this detailed description, with each claim standing on its own as a separate embodiment of this invention.

All of the features disclosed in this specification (including any accompanying claims, abstract and drawings), and all of the processes or elements of any method or apparatus so disclosed, may be combined in any combination, except combinations where at least some of such features and/or processes or elements are mutually exclusive. Each feature disclosed in this specification (including any accompanying claims, abstract and drawings) may be replaced by alternative features serving the same, equivalent or similar purpose, unless expressly stated otherwise.

Furthermore, those skilled in the art will appreciate that while some embodiments described herein include some features included in other embodiments, rather than other features, combinations of features of different embodiments are meant to be within the scope of the invention and form different embodiments. For example, in the following claims, any of the claimed embodiments may be used in any combination.

It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design alternative embodiments without departing from the scope of the appended claims. In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. The word "comprising" does not exclude the presence of elements or steps not listed in a claim. The word "a" or "an" preceding an element does not exclude the presence of a plurality of such elements. In the unit claims enumerating several means, several of these means may be embodied by one and the same item of hardware. The usage of the words first, second and third, etcetera do not indicate any ordering. These words may be interpreted as names.

Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
