Referring to fig. 1 to 3, an embodiment of the present invention provides an electric cooking appliance 100, which includes a housing 10 and a heating element 20, wherein the housing 10 forms a receiving chamber 111. The heating element 20 is disposed in the accommodating chamber 111, the heating element 20 can rotate around the preset space 714 relative to the housing 10, and the motion track of the heating element 20 envelopes the preset space 714.

According to the cooking appliance 100 of the embodiment of the invention, food can be placed in the preset space 714, and the heating element 20 can rotate around the preset space 714 relative to the housing 10 and envelope the preset space 714, that is, the heating element 20 can rotate around the food, so that the food is heated more uniformly, and the heating or baking of the food is facilitated.

In this embodiment, the heating element 20 can heat the preset space 714, and since the heating element 20 can rotate around the preset space 714 and envelop the preset space 714, the heat can be uniformly dissipated to the preset space 714, and then the preset space 714 can be uniformly heated, so that the food to be heated in the preset space 714 can be heated more uniformly, the occurrence of the condition that the food is heated non-uniformly is prevented, and the heating or baking of the food is facilitated.

Wherein, the shell 10 can be made of stainless steel, and stainless steel has the hardness height and high temperature resistance's advantage, so can prevent the condition that shell 10 is damaged by hot gas, promotes the life of shell 10 to promote cooking appliance 100's life. It is understood that the housing 10 may be made of stainless steel, and the specific material of the housing 10 may be set according to different situations. For example, in other embodiments, the housing 10 may also be made of iron. The specific material of the housing 10 is not limited herein.

It is understood that the predetermined space 714 is an inner space of the housing 10, and the predetermined space 714 may be a sphere or a cube. The specific shape of the predetermined space 714 is not limited herein.

The movement track of the heating element 20 enveloping the preset space 714 means that the heating element 20 rotates around the periphery of the preset space 714, and the space formed by the heating element 20 in the rotating condition wraps the preset space 714, that is, the preset space 714 is located inside the space formed by the heating element 20 in the rotating condition.

Referring further to fig. 1 to 5, in some embodiments, the heating element 20 includes a first heating pipe 21 and a second heating pipe 22 rotatably connected to the first heating pipe 21, the first heating pipe 21 rotates around a first axis P, the second heating pipe 22 rotates around a second axis Y, the first axis P intersects the second axis Y, and a movement path formed by the first heating pipe 21 and the second heating pipe 22 envelops the predetermined space 714.

The motion track enveloping preset space 714 formed by the first heating pipe 21 and the second heating pipe 22 means that the motion track enveloping preset space 714 of at least one of the first heating pipe 21 and the second heating pipe 22, or the motion track formed by the first heating pipe 21 and the second heating pipe 22 can envelop the preset space 714 after being superimposed, and the following two cases are explained respectively:

in the case where the movement locus of at least one of the first heating pipe 21 and the second heating pipe 22 envelopes the preset space 714, the movement locus of one of the first heating pipe 21 and the second heating pipe 22 envelopes the preset space 714, or the movement locus of both the first heating pipe 21 and the second heating pipe 22 envelopes the preset space 714.

The movement locus of one of the first heating pipe 21 and the second heating pipe 22 enveloping the preset space 714 is explained as follows:

one of the first heating pipe 21 and the second heating pipe 22 rotates around the outer circumference of the preset space 714, and a space formed by the one of the first heating pipe 21 and the second heating pipe 22 in the rotating state can wrap the preset space 714, that is, the preset space 714 is located inside the space formed by the one of the first heating pipe 21 and the second heating pipe 22 in the rotating state.

The following explains the movement trajectories of the first heating pipe 21 and the second heating pipe 22 both enveloping the predetermined space 714:

in this embodiment, the first heating pipe 21 can rotate around the first axis P, the movement track of the first heating pipe 21 envelops the preset space 714, the second heating pipe 22 can rotate around the second axis Y, the movement track of the second heating pipe 22 envelops the preset space 714, and the first axis P is perpendicular to the second axis Y, so that, under the condition that the first heating pipe 21 and the second heating pipe 22 rotate, the first heating pipe 21 and the second heating pipe 22 are matched to enable heat to be uniformly and sufficiently dissipated to the preset space 714, and further the preset space 714 can be uniformly heated. Of course, in other embodiments, the first axis P may also be at an angle, such as an acute angle or an obtuse angle, with the second axis Y. That is, in other embodiments, the first axis P and the second axis Y may not be perpendicular. It is not limited whether the first axis P and the second axis Y are perpendicular.

In the present embodiment, the number of the first heating pipes 21 is 1, the first heating pipes 21 are circular, the number of the second heating pipes 22 is 2, and the 2 second heating pipes 22 are semicircular. In such an embodiment, 2 second heating pipes 22 are located in the annular space of the first heating pipe 21 and are arranged opposite to each other, the 2 second heating pipes 22 having the same diameter. Since the 2 second heating pipes 22 are located in the annular space of the first heating pipe 21, the predetermined space 714 is located between the 2 second heating pipes 22, that is to say, the predetermined space 714 can be enveloped by the movement trajectories of the first heating pipe 21 and the second heating pipe 22 when the first heating pipe 21 and the second heating pipe 22 rotate. In this way, the heat generated by the first heating pipe 21 and the second heating pipe 22 can be uniformly dissipated to the predetermined space 714, so that the predetermined space 714 is uniformly heated.

Of course, in other embodiments, the 2 second heating pipes 22 may also be located outside the annular space of the first heating pipe 21, or one of the 2 second heating pipes 22 is located inside the annular space of the first heating pipe 21 and another one of the 2 second heating pipes 22 is located outside the annular space of the first heating pipe 21. The predetermined space 714 can be enveloped by the movement trajectories of the first heating pipe 21 and the second heating pipe 22 only when the first heating pipe 21 and the second heating pipe 22 rotate. Specific positions of the second heating pipe 22 and the first heating pipe 21 are not limited herein.

It is understood that the number of the first heating pipes 21 may be not only 1, but also the number of the second heating pipes 22 may be not only 2. For example, in other embodiments, the number of the first heating pipes 21 is 1, the number of the second heating pipes 22 is 1, the second heating pipes 22 are located within the annular space of the first heating pipes 21, or the second heating pipes 22 are located outside the annular space of the first heating pipes 21. The predetermined space 714 can be enveloped by the movement trajectories of the first heating pipe 21 and the second heating pipe 22 only when the first heating pipe 21 and the second heating pipe 22 rotate. The specific number of the first heating pipe 21 and the second heating pipe 22 is not limited herein.

The fact that the movement path formed by the first heating pipe 21 and the second heating pipe 22 can be wrapped around the preset space 714 after being superimposed on each other means that the movement path formed by the first heating pipe 21 in the rotating state cannot be wrapped around the preset space 714 and the movement path formed by the second heating pipe 22 in the rotating state cannot be wrapped around the preset space 714, and the movement path formed by the first heating pipe 21 in the rotating state and the movement path formed by the second heating pipe 22 in the rotating state can be wrapped around the preset space 714 after being superimposed on each other, for example, the space formed by the first heating pipe 21 in the rotating state wraps a first part of the preset space 714, the space formed by the second heating pipe 22 in the rotating state wraps a second part of the preset space 714, and the first part is superimposed on the preset space, so that the movement path formed by the first heating pipe 21 in the rotating state and the movement path formed by the second heating pipe 22 in the rotating state are superimposed on each other The preset space 714 can then be enveloped.

Of course, in some embodiments, one of the first and

second heating pipes

21 and 22 may be omitted. In such an embodiment, it is only necessary that the movement trajectory of the other of the first heating pipe 21 and the second heating pipe 22 can envelope the preset space 714.

In one embodiment, the first heating pipe 21 and the second heating pipe 22 may be electric heating pipes, and in such an embodiment, heat generated after the electric heating pipes are energized is directly emitted to the predetermined space 714. It is understood that the first heating pipe 21 and the second heating pipe 22 may not be only the electric heating pipes. The specific types of the first heating pipe 21 and the second heating pipe 22 may be specifically set according to different situations.
