Description

Technical Field

[0001] This utility model relates to the field of cooking equipment technology, and in particular to an electric heating cooking appliance in which the heating plate protrudes from the top of the appliance body and is in clearance fit with the surface of the upper shell. Background Technology

[0002] The existing electric heating plates of electric cooking appliances (hereinafter referred to as cooking appliances) are set in two ways: they are recessed into the body and they protrude from the top of the body. For example, electric rice cookers and electric pressure cookers are recessed, while experimental ovens are protruding.

[0003] Although submerged furnaces have higher thermal efficiency, they also have drawbacks such as difficulty in cleaning the interior and poor versatility. While the protruding structure of experimental furnaces solves the problems of cleaning and versatility, the heating plate not only contacts the furnace at the mounting point but also at the top surface, resulting in a high overall temperature rise for experimental furnaces and similar products, sometimes even to the point of being scalding hot. This limits the application of such products. Utility Model Content

[0004] The present invention aims to install the heating plate protruding from the top of the apparatus body and to make the bottom of the heating plate and the top surface of the upper shell fit together with a gap, so as to reduce the contact area between the heating plate and the apparatus body, avoid the heat of the heating plate being transferred to the apparatus body in the form of heat conduction, and at the same time utilize the air flow around the gap to release and reduce the impact of the heat radiation of the heating plate on the apparatus body, thereby effectively solving the problem of overall temperature rise of experimental furnaces and similar products.

[0005] To achieve the above objectives, the technical solution of this utility model is a cooking appliance with a protruding electric heating plate, comprising:

[0006] The appliance body is the main body of the cooking appliance, including: an upper shell, a base, a power cord, a control panel disposed in the upper shell and the base, and wires for electrical connection between electrical components;

[0007] The heating plate is an electric heating device that protrudes from the top of the device body and has a gap fit between its bottom and the surface of the upper shell.

[0008] Furthermore, the aforementioned cooking appliance with a protruding heating plate is a resistance heating device that is round, square, or elliptical, and is flat or concave-convex in shape.

[0009] Furthermore, in the aforementioned cooking appliance with a protruding heating plate, the heating plate is a cast aluminum heating plate with an electric heating tube, or a cast iron heating plate with an electric heating tube, or a resistance wire composite heating plate, or a heating film composite heating plate, or a graphene composite heating plate.

[0010] The beneficial effects of this invention are that, because the heating plate is positioned protruding from the top of the apparatus body with a gap fit, even if the operating temperature of the heating plate is increased, the temperature rise of the apparatus body can be guaranteed to remain within the safety regulations. This effectively expands the application scenarios of experimental furnaces and similar products, and lays the foundation for the iterative upgrade of submerged heating plate products. Other effects will be partly set forth in the description below, and partly become apparent from the following description, or may be learned from practice of this invention.

[0018] The following is for reference. Figures 1 to 4 This invention describes a cooking appliance with a protruding electric heating plate.

[0019] The technical solution of this utility model is a cooking appliance with a protruding electric heating plate, comprising:

[0020] The appliance body 100 is the main body of the cooking appliance, including: an upper shell 2, a base 1, a power cord, a heating plate, a control board 4 disposed in the upper shell and the base, and wires for electrical connection between electrical components.

[0021] The heating plate 3 is an electric heating device that protrudes from the top of the device body and has a gap fit between its bottom and the surface of the upper shell.

[0022] Furthermore, the aforementioned cooking appliance with a protruding heating plate is a circular, square, or elliptical resistance heating device that is flat or concave-convex, such as a cast aluminum heating plate with a heating tube, a cast iron heating plate with a heating tube, a resistance wire composite heating plate, a heating film composite heating plate, or a graphene composite heating plate.

[0023] Furthermore, the following combination Figures 1-4 The present invention provides a further description of a cooking appliance with a protruding electric heating plate.

[0024] like Figure 1 and Figure 2 The illustrated embodiment of the cooking appliance with a protruding heating plate includes:

[0025] The appliance body is the main body of the cooking appliance, including: an upper shell, a base, a power cord, a control panel disposed in the upper shell and the base, and wires for electrical connection between electrical components. Further, the base and / or the upper shell are devices provided with air inlet and outlet holes.

[0026] The electric heating plate is a circular, flat heating device made of resistance wire composite. It is supported by a base and protrudes from the top of the device body through a mounting bracket. The bottom of the plate is in a gap fit with the surface of the upper shell.

[0027] The cooking appliance with a protruding heating plate described in this embodiment has several advantages. First, because the heating plate protrudes from the appliance body, it avoids the high-temperature, multi-directional, and large-area heat radiation effect of the heating plate on the appliance body. Second, because the heating plate is mounted on the appliance body using a bracket, a gap H between the heating plate and the upper shell effectively blocks the high-temperature conduction of heat from the heating plate to the upper shell through the bottom. At the same time, the air flowing around the gap carries away and releases the heat radiated from the bottom of the heating plate to the upper shell. Furthermore, by adjusting the size of the gap between the heating plate and the upper shell, the temperature of the heat radiated from the heating plate to the upper shell can be adjusted. The size and flow rate of the air flowing through the gap can also be adjusted to change the amount of heat carried away and released from the upper shell, thereby controlling the temperature of the upper shell. This ensures that the temperature rise of the appliance body meets safety requirements, thus enabling a wider range of applications.

[0029] The appliance body is the main body of the cooking appliance, including: an upper shell, a base, a power cord, a heating plate, a control board disposed in the upper shell and the base, and wires for electrical connection between electrical components; the heating plate is supported by the base through a mounting bracket and protrudes from the top of the appliance body, with its bottom fitting with the surface of the upper shell with a clearance, and is a convex electric heating device made of cast aluminum heating tube, which is round, square, or oval.

[0030] like Figure 4 The illustrated embodiment of the cooking appliance with a protruding heating plate includes:

[0031] The appliance body is the main body of the cooking appliance, including: an upper shell, a base, a power cord, a heating plate, a control board disposed in the upper shell and the base, and wires for electrical connection between electrical components; the heating plate is a heating device made of graphene composite, which is supported by the base through a mounting bracket and protrudes from the top of the appliance body, with its bottom in a gap fit with the surface of the upper shell, and is circular, square, or elliptical in a concave shape.
