Description

Technical Field

[0001] The utility model relates to the technical field of heating plates of electric cookers, and specifically to a household electric cooker burner head. Background Art

[0002] The principle of an electric cooker is to heat by using the heat dissipated when an electric current passes through a resistance wire.

[0003] The inventor of the present utility model found that in most of the existing burner heads of electric heating tube type electric stoves, the electric heating tubes are rigidly supported by several metal fulcrums. This can cause problems such as the collapse and damage of the electric heating tubes due to insufficient support points and the inability to release stress, resulting in damage. At the same time, since such burner heads do not have a heat insulation layer, the temperature inside the electric stove will be too high, causing a decrease in lifespan and energy waste. During use, not only is it easy to deform and damage, but it is also impossible to achieve a higher heating temperature, making it difficult to achieve the effect of stir-frying. Additionally, the traditional fixing method of the burner head is to connect the bottom shell with a central screw, and the screw will conduct a large amount of heat to the bottom shell in a conductive manner, making the internal environment even worse. Summary of the Utility Model

[0004] The purpose of the present utility model is to provide a household electric cooker burner head, aiming to improve the structure in which most of the existing burner heads of electric stoves have electric heating tubes rigidly supported by several metal fulcrums. Due to insufficient support points and the lack of a stress release structure, problems such as the collapse or deformation and damage of the electric heating tubes will occur. The present utility model correspondingly adds a support heat storage plate to support the electric heating tube, adds a high-performance heat insulation cotton as a heat insulation layer, cancels the rigid fixing points to release the stress of the electric heating tube, and at the same time optimizes the fixing method of the burner head, thus improving some drawbacks of the existing electric stoves.

[0005] The present utility model is implemented as follows:

[0006] A household electric cooker burner head includes an electric heating tube, a support heat storage plate, a heat insulation layer, and a metal support bowl. The electric heating tube is spiral and is mainly supported by the support heat storage plate, and the wiring end of the electric heating tube is ensured to be long enough and then fixed after passing through the support heat storage plate, the heat insulation layer, and the metal support bowl. The support heat storage plate is mainly made of fired clay and has the functions of support and heat storage. The heat insulation layer is a cotton-like high-performance heat insulation material used to prevent heat from being introduced into the interior of the electric stove. The metal support bowl is the outer shell of this burner head and has the functions of support, protection, heat insulation, and heat dissipation.

[0007] Furthermore, the wiring end part of the electric heating tube does not generate heat. The wiring end of the electric heating tube passes through the support heat storage plate, the heat insulation layer, and the metal support bowl and then bends horizontally. The length of the bent part of the wiring end of the electric heating tube is not less than 5 cm. The electric heating tube is in direct contact with the container to be heated during use.

[0008] Further, the support heat storage plate is arranged between the electric heating tube and the heat insulation layer, and its upper surface is attached to the electric heating tube to provide support force for the electric heating tube. The support heat storage plate is made of fired clay, and metal heat conduction sheets can be added between the support heat storage plate and the electric heating tube bracket to improve the temperature uniformity.

[0009] Further, the heat insulation layer is composed of cotton-like high-performance heat insulation material, which is mainly used to prevent heat from conducting into the interior of the electric cooker.

[0010] Further, the metal bowl is the housing of the burner of this electric cooker. It wraps the heat insulation layer and the support heat storage plate and is fixed on the panel of the cooker. The panel can be tempered glass or other panel materials. Heat dissipation holes are provided at the edge of the metal bowl, which can allow air circulation between the interior of the cooker and the surrounding environment.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: By studying the structure and use process of the traditional electric stove burner assembly, the present utility model designs a household electric cooker burner. When in use, due to the support and stress release of the support heat storage plate, the electric heating tube will not collapse and deform, and the service life can be greatly improved. The addition of the heat insulation layer prevents heat from conducting into the interior of the electric cooker, enabling the internal components of the electric cooker to work in a more suitable environment, while preventing heat waste. This can not only meet the usage habits of consumers but also ensure safety and quality. BRIEF DESCRIPTION OF THE DRAWINGS
