As shown in fig. 1-3, an embodiment of the present invention provides a pressure cooking appliance, which includes a pot body 100 and a pot cover 200 disposed on the pot body 100 in a removable manner. The pot body 100 comprises an outer cover 110, a heat preservation cover 120 arranged on the inner side of the outer cover 110, and a power panel assembly 130 positioned between the outer cover 110 and the heat preservation cover 120, wherein a heat dissipation channel 140 is arranged on one side of the power panel assembly 130, which is close to the outer cover 110, and a spacer 150 is arranged between the heat dissipation channel 140 and the outer cover 110.

In this embodiment, the heat dissipation channel 140 is disposed at a side close to the outer cover 110, and a certain distance exists between the power board assembly 130 and the outer cover 110, so as to prevent heat generated by the power board assembly 130 from directly acting on the outer cover 110, thereby facilitating heat dissipation of the power board assembly 130. In addition, although the present embodiment is not limited to the specific structure and shape of the heat dissipation channel 140, it is preferable that, for example, the top end of the heat dissipation channel 140 is closed, so that the cool air generated by the heat dissipation structure (such as the fan assembly 170 described below) in the pan body 100 can flow along a specific path. It should be noted that the heat dissipation channel 140 of this specific path has two different heat dissipation methods according to the size of its own gap: when the heat dissipation channel 140 is a small gap, according to the venturi effect, the flow velocity of the air flow inside the heat dissipation channel 140 is correspondingly increased, so that the inside of the heat dissipation channel 140 is in a negative pressure state, and the air outside the heat dissipation channel 140 is sucked into the power panel assembly 130 under the action of the atmospheric pressure to dissipate heat; when the heat dissipation channel 140 is a large gap, the heat dissipation channel 140 can be used as an air outlet to discharge hot air inside the power board assembly 130 to the outside, thereby improving the heat dissipation performance of the power board assembly 130.

It should be understood that the size of the gap of the heat dissipation channel 140 depends on the position of the spacer 150, since the spacer 150 can be disposed on the inner sidewall of the housing 110 and the power board assembly 130. Therefore, when the spacer 150 is disposed on the outer cover 110, the gap of the heat dissipation channel 140 is larger, so that the heat dissipation channel 140 adopts the latter heat dissipation manner; when the spacer 150 is disposed on the power board assembly 130, the gap of the heat dissipation channel 140 is smaller, so that the heat dissipation channel 140 adopts the former heat dissipation manner.

It should be noted that the distance between the heat dissipation channel 140 (or the spacer 150) and the outer casing 110 should be considered according to safety regulations, product design requirements, and manufacturing processes, so as to ensure the heat dissipation effect of the power board assembly 130 and to make the product have a smaller volume.

In addition, the isolation member 150 in this embodiment can achieve an insulating effect in addition to a heat insulation effect, so that on one hand, heat generated by the power board assembly 130 can be prevented from being directly transferred to the outer cover 110, thereby improving the safety of the pressure cooking appliance in the using process and avoiding scalding a user; on the other hand, the spacer 150 can block the electric spark possibly generated by the power strip assembly 130, thereby further improving the safety of the product.

In view of the above, the spacer 150 in the present embodiment may be a mica sheet, for example. Of course, the material of the spacer 150 is not limited in this embodiment, and other materials having the same dual functions of heat insulation and insulation can also be used as the spacer 150. In addition, the structure and shape of the spacer 150 are not limited in this embodiment, and specifically, the spacer 150 may be rectangular, circular, square, or the like; the area of the spacer 150 may be equal to the area of the power panel assembly 130, or may be larger than the area of the power panel assembly 130.

As a preferred implementation manner of the embodiment of the present invention, the bottom end and/or both sides of the heat dissipation channel 140 are at least partially opened. The term "at least partial opening" used herein includes two layers of meanings of a whole opening and a partial opening, and any kind of opening structure can make the heat dissipation channel 140 have a better air exhaust effect, thereby preventing cold air flowing through the power board assembly 130 from generating a backflow phenomenon after becoming hot air, and further improving the heat dissipation effect of the power board assembly 130. Moreover, the heat dissipation channel 140 with such a structure can be communicated with the inner space of the pot body 100, so that the heat dissipation range of the power panel assembly 130 is expanded to a certain extent, and the improvement of the heat dissipation effect is facilitated.

In one embodiment, referring to fig. 2 and 4, the power board assembly 130 includes a power board body 131 and a power board cover 132 between the heat-insulating cover 120 and the power board body 131.

In this embodiment, the power board cover 132 is arranged to fix the power board body 131, and the power board cover 132 can protect the power board body 131 to some extent, so as to improve the safety of the product and the stability of the product during use. In addition, the arrangement of the bracket 133 on the power board cover 132 not only enables the fan assembly 170 to radiate heat to the power board assembly 130, but also enables cold air generated by the fan assembly 170 to act on the heating element 160, thereby reducing the temperature of the heating element 160. This way of simultaneously acting on the power board assembly 130 and the heating element 160 by one fan assembly 170 can, on the one hand, significantly reduce the production cost of the pressure cooking appliance and, on the other hand, facilitate the miniaturization of the volume of the pressure cooking appliance.

As a preferred implementation manner of the embodiment of the present invention, referring to fig. 5 and 6, the two sides of the power board cover 132 are respectively provided with a first connecting portion 134 and a second connecting portion 135 connected to the power board body 131, and the middle of the power board cover 132 is provided with a third connecting portion 136 for fixing the spacer 150.
