Pot cover and cooking utensil

Technical Field

The utility model relates to a household electrical appliances technical field particularly, relates to a pot cover and cooking utensil.

Background

The air outlet of the cover body of the existing pressure baking integrated cooker is mostly opened, the air outlet which is opened is not used for effectively changing the flowing direction of air, and then the heat is not uniform on the cover body, so that the temperature field is not uniform, and the food can not be uniformly baked.

That is, the cooking appliance in the prior art has a problem of uneven temperature field.

SUMMERY OF THE UTILITY MODEL

The main object of the utility model is to provide a pot cover and cooking utensil to cooking utensil has the inhomogeneous problem of temperature field among the solution prior art.

In order to achieve the above object, according to an aspect of the present invention, there is provided a pot cover, including: the air inlet cavity is positioned on one side of the pot cover; the air outlet of the air inlet cavity is arranged on the side wall of the air guide groove and supplies air to the air guide groove; the shunting structure is arranged in the air guide groove and is provided with at least two diversion surfaces so as to shunt the incoming air of the air inlet cavity into at least two air outlet directions through the shunting structure.

The air inlet cavity is arranged to blow hot air into the air guide groove, and the hot air in the air guide groove flows into the baking space to bake food. The setting of reposition of redundant personnel structure can change hot-blast flow direction for hot-blast direction flow to the difference, and then increased the region that hot-blast flowed through, make the heat in the wind-guiding groove more even, make the temperature field of pot cover more even, in order to realize the purpose of even toasting.

Furthermore, the at least two flow guide surfaces comprise two lateral flow guide surfaces, the projections of the two lateral flow guide surfaces on the bottom of the air guide groove are in a herringbone shape or a splayed shape, and one ends, close to each other, of the two lateral flow guide surfaces are close to the air inlet cavity relative to the ends, far away from each other, of the two lateral flow guide surfaces. The heat energy can follow the side edge of the shape flow channel air guide groove of the lateral flow guide surface by the arrangement, so that the heat in the air guide groove is more uniform, the purpose of uniform temperature field is achieved, and uniform baking is realized.

Furthermore, the at least two guide surfaces comprise two lateral guide surfaces and a connecting guide surface, and one ends of the two lateral guide surfaces, which are far away from the bottom of the air guide groove, are connected through the connecting guide surface. The arrangement of the connecting guide surfaces can guide the hot air between the two lateral guide surfaces, so that the hot air can smoothly flow to one side away from the air inlet cavity, the area through which the hot air can flow is increased, and the temperature field in the air guide groove is more uniform.

Furthermore, the projections of the two lateral flow guide surfaces on the bottom of the air guide groove are splayed, the flow distribution structure further comprises a connecting surface, and the lateral flow guide surfaces and the edge of one side of the connecting flow guide surface, which is close to the air inlet cavity, are connected by the connecting surface. The arrangement of the connecting surface enables hot air to flow to the positions of the two lateral flow guide surfaces when the hot air collides with the connecting surface, and the hot air flows to each position of the air guide groove under the action of the lateral flow guide surfaces. The arrangement is such that a large part of the hot air is guided away by the lateral flow guide surfaces.

Furthermore, the lowest point of the air outlet is lower than the connecting flow guide surface; and/or the highest point of the air outlet is higher than the connecting flow guide surface. Set up like this and make to connect the water conservancy diversion face and be located air outlet department for at least some wind that flows from the air outlet can flow along connecting the water conservancy diversion face, and at least another part wind can flow along two side direction water conservancy diversion faces, flows in order to realize the wind of three direction, so that hot-blast each position that can flow the guide duct, flows into the space of toasting through the opening simultaneously, in order to realize evenly toasting.
