The inventor discovers that the phenomenon of short circuit of the heating wire can occur after a large number of experiments are carried out on the pressure cooker with the baking function in the related technology, and food residues are sucked into the air duct by the centrifugal fan blade and finally attached to the heating wire due to the fact that no filtering structure is arranged at the air inlet of the air duct, so that the heating wire has potential safety hazards of burning off and machine ignition.

The technical scheme of the application can effectively solve the problems. The technical solution of the present application will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, the cooking appliance of the present embodiment includes: a pot body 10, an inner pot 20, a heat generating member 30 and a filtering structure 40. The pot body 10 has an air duct having an air inlet 11 and an air outlet 12. The inner pot 20 is arranged in the pot body 10, and the heating element 30 is arranged at the air outlet 12. The filtering structure 40 is disposed in the cooker body 10 through the first inserting structure, and the filtering structure 40 is located at the air inlet 11.

By applying the technical scheme of the embodiment, the air inlet 11 of the air duct is provided with the filtering structure 40, and the filtering structure 40 can effectively block food residues so that the food residues are attached to the filtering structure 40. Thus, the food waste cannot reach the heat generating member 30, and the short circuit of the heat generating member 30 does not occur. Meanwhile, in consideration of the arrangement space problem (the problem that the interval between the pot body 10 and the inner pot 20 is small), the filter structure 40 is provided in the pot body 10 through the first insertion structure. The first inserting structure can effectively reduce the installation space, and then the first inserting structure and the filtering structure 40 only need to occupy a small inner space, and the installation of the filtering structure 40 can be realized under the condition that the distance between the cooker body 10 and the inner pot 20 is small.

In order to facilitate the cleaning of the food waste attached to the filter structure 40, in the present embodiment, the filter structure 40 is detachably coupled to the pot body 10.

As shown in fig. 2, the intake vent 11 includes a plurality of intake holes provided in the heat-retaining cover 14. The heat-retaining cover 14 is made of metal, and it is necessary to maintain a certain thickness of the heat-retaining cover 14 in consideration of the heat-retaining effect and strength of the heat-retaining cover 14. Therefore, the aperture of the air inlet hole is difficult to be made smaller, and food residues cannot be blocked. Therefore, the filtering structure 40 is provided inside the heat-retaining cover 14 to block the food waste. To facilitate installation of the filter structure 40, a first plug-in structure is provided between the filter structure 40 and the heat retention cover 14.

That is, the pot body 10 may be used in cooperation with the roast cover 50, or in cooperation with the pressure cover. The cooking appliance can simultaneously realize two cooking modes of baking and pressure. In consideration of the pressure cooking mode, the distance between the inner pot 20 and the heat preservation cover 14 should not be too large (the large distance may cause the inner pot to shake, which affects the pressure cooking function). Therefore, the arrangement space left for the filter structure 40 is limited. Just through first grafting structure connection filtration 40 and heat preservation cover 14 for filtration 40 and first grafting structure are thinner, make cooking utensil can compromise filtration efficiency and pressure culinary art function, and then have solved the electric pressure cooker of area toasting function and have hardly installed the problem of filtration.
