Description

Technical Field

[0001] The invention relates to a kitchen appliance, in particular to a food processor with stirring and heating functions. The food processor is provided with a double-layer bottom cover structure. Background Art

[0002] Existing food processors usually have a stirring function, and mainly include: a body with a rotational driving function; a cup body mounted on the body; and a stirring tool mounted in the cup body and driven by the body to rotate. Such food processors may also have a heating device arranged at the bottom area of ​​the cup body to heat the food in the cup body.

[0003] For example, CN103565301A discloses an electric food processor. The electric food processor includes a pot body, a handle, a pot body cover, a heating component fixed to the bottom of the pot body, a machine body, a driving motor located in the machine body, and a stirring knife group located in the pot body. When the machine is powered on, the machine body supplies power to the heating component to heat the food in the pot body, and the driving motor in the machine body drives the stirring knife group to rotate to stir the food in the pot body.

[0004] For food processors with heating functions, in order to heat the food evenly and prevent the bottom from getting burnt, it is usually necessary to pre-treat the inside of the cup body. Usually, after the inside of the cup body is surface treated, the bottom cover encapsulating the heating component is joined to the bottom of the cup body by welding. However, the high temperature during the welding process often damages the surface treatment layer formed inside the cup body, which is particularly obvious at the location where the bottom of the cup body is welded to the bottom cover.

[0005] It has been conceived to perform surface treatment on the inside of the cup body after welding the bottom cover to the cup body. However, since many electrical components of the heating circuit are encapsulated in the bottom cover, the environment of the surface treatment process is likely to damage the electrical components of the heating circuit. The damaged electrical components need to be destroyed to be replaced by destroying the bottom cover welded to the cup body, which greatly increases the manufacturing cost and consumes a lot of time.

[0006] Therefore, it is desirable to provide a food processor that can overcome the above-mentioned disadvantages. Summary of the invention

[0007] In order to solve the deficiencies of the food processor in the prior art, the present invention provides a food processor with a double-layer bottom cover structure.

[0008] The technical solution adopted by the present invention to solve the technical problem is to provide a food processor, which includes: a body assembly, a cup assembly, a screen assembly and a base, wherein the cup assembly includes a cup body, a cup cover, a stirring knife arranged in the cup body and a heating device arranged at the bottom of the cup body, wherein the interior of the cup body undergoes surface treatment to ensure that the food is heated evenly and does not get stuck on the bottom, and the surface treatment is performed after the bottom of the cup body is welded to the first bottom cover, and after the interior of the cup body undergoes surface treatment, the second bottom cover is welded to the first bottom cover.

[0009] According to a preferred embodiment of the present invention, the heating device includes a heating film arranged between the bottom of the cup body and the first bottom cover and a heating circuit arranged between the first bottom cover and the second bottom cover.

[0010] According to a preferred embodiment of the present invention, the cup cover can be rotatably buckled onto the cup body, and the food processor can be powered on and operated only when the cup cover is buckled into place on the cup body.

[0011] According to a preferred embodiment of the present invention, the cup body, the first bottom cover and the second bottom cover are made of stainless steel.

[0012] According to a preferred embodiment of the present invention, a handle is provided on the side of the cup body, and a connecting rod is arranged in a channel formed between the side of the cup body and the handle. The connecting rod is connected to the buckle. When the cup cover is buckled into place on the cup body, the connecting rod moves in the channel, driving the buckle to trigger the switch, thereby powering on the food processor.

[0013] According to a preferred embodiment of the present invention, a sealing ring is sandwiched between the cup body and the cup cover.

[0014] According to a preferred embodiment of the present invention, a driving motor and a transmission mechanism are provided in the body assembly, and the rotation of the driving motor is transmitted to the stirring cutter through the transmission mechanism.

[0015] According to a preferred embodiment of the present invention, the stirring tool comprises a stirring rod and a blade fixed thereon, and the stirring tool is connected to the transmission mechanism via a tool lock buckle.

[0016] According to a preferred embodiment of the present invention, the transmission mechanism comprises a pulley transmission mechanism.
