In view of this, the present invention proposes a cooking appliance comprising: a cooking cavity; the air inlet assembly comprises an air channel, a first fan and a controller assembly, the air channel is connected with the cooking cavity, the first fan is connected with the air channel and is used for driving air flow to flow into the air channel, the controller assembly is positioned in the air channel, and at least two air outlets are arranged on the air channel; at least two air guide pipelines, wherein the air guide pipelines are connected with the cooking cavity, and one air guide pipeline is communicated with one air outlet; at least two functional components connected with the cooking cavity; the air guide pipeline is used for blowing air flow towards the functional component so as to radiate heat of the functional component.

An air inlet assembly is arranged on the cooking cavity, and the air inlet assembly can suck air with lower external temperature into the air inlet assembly, so that the air inlet assembly is used for radiating heat of the controller assembly and the functional assembly.

Specifically, the air inlet assembly includes wind channel, first fan and controller subassembly, and the wind channel is installed on the culinary art cavity, and first fan and controller subassembly are installed in the wind channel, and wind channel, first fan and controller subassembly can be connected through welded mode, perhaps fix through retaining members such as screw, and details are omitted here.

The first fan can suck external air into the air duct and form flowing air flow in the air duct, and the controller assembly is arranged in the air duct, so that the air flow in the air duct can flow through the controller assembly, and heat dissipation is carried out on the controller assembly. The controller component can generate a large amount of heat during operation, and the controller component is radiated through flowing air flow, so that the heat generated by the controller component can be taken away rapidly, the temperature of the controller component is reduced, and the stable operation of the controller component is ensured.

An air outlet is arranged on the air duct, and air flow in the air duct can flow out through the air outlet. The air guide pipeline is communicated with the air outlet, so that air flow flowing out of the air outlet can flow into the air guide pipeline. Still install the functional module on the culinary art cavity, the functional module also can produce heat when the operation, and the air duct can lead the air current to the functional module to realize the heat dissipation to the functional module, guarantee the temperature operation of functional module.

When heating the food in the cooking cavity, the temperature in the cooking cavity is higher, and the controller component and the functional component are radiated through flowing air flow, so that the influence of the cooking cavity with higher temperature on the controller component and the functional component can be reduced.

Different functional units can correspond to different air guide pipelines, so that the condition that one air guide pipeline simultaneously dissipates heat to a plurality of functional units is avoided, the temperature in each air guide pipeline is ensured to be relatively low, and therefore the functional units are effectively dissipated.

The air flow is sucked into the air duct through the first fan, and the air duct and the air guide pipeline are communicated, so that flowing air flow can radiate the controller component and the functional component, the controller component and the functional component do not need an independent radiating system, and the controller component and the functional component are effectively radiated on the basis of simplifying the structure.

The heating element in the cooking utensil and the heat of the heated vulnerable part are taken away through the specific air duct system structure, so that the phenomenon of local high temperature in the cooking utensil is avoided, the normal work of the cooking utensil is maintained, and the service life of the cooking utensil is prolonged.

In addition, the air flow can also take away part of steam in the cooking cavity 110, so that the humidity in the cooking cavity 110 can be reduced, and the cooking effect on food materials can be improved.

The air flow formed when the first fan 220 rotates not only can radiate heat to the controller assembly 230 and the functional assembly 400, but also can take away the oil smoke or steam in the cooking cavity 110, and the device which is independently arranged in the cooking cavity 110 for exhausting the oil smoke and the steam is not needed, so that the structure of the cooking appliance is simplified, and the functionality of the cooking appliance is improved.

Moreover, since the air flowing into the cooking cavity 110 passes through the controller assembly 230 and the function assembly 400, the temperature of the air entering into the cooking cavity 110 is high, and the temperature in the cooking cavity 110 is not easily lowered, thereby avoiding the influence on the cooking process.

Since the number of the air guide duct 300 is at least two, the number of the air inlets 120 may be set to be at least one, for example, two air inlets 120 are provided on the cooking cavity 100 to simultaneously intake air.

As shown in fig. 16, in any of the above embodiments, the cooking cavity 100 is provided with a first sidewall 140 and a second sidewall 150, the first sidewall 140 and the second sidewall 150 are disposed opposite to each other, the air inlet 120 is disposed on the first sidewall 140, and the air outlet 130 is disposed on the second sidewall 150.

For example, if the inlet 120 and the outlet 130 are provided on adjacent sidewalls, the airflow needs to be "turned" and then discharged, which reduces the discharge rate of the airflow. Therefore, by disposing the air inlet 120 and the air outlet 130 on the two opposite sidewalls of the cooking cavity 100, the air flow can quickly take away the oil smoke or steam in the cooking cavity 110, which is beneficial to improving the cooking effect on the food materials.
