Description

New structure of electric cooker

The present invention relates to a new structure of an electric cooker, in particular to a new structure of a separate electric cooker composed of a base, a pot body and a lid.

According to the traditional electric cooker, the outer shell and the middle pot are inseparable, because the heating device is fastened to the bottom of the middle pot. This structure has been in use for several decades, but few people have researched and improved it. Therefore, most people think that the electric cooker can only be used for cooking or stewing food, and the middle pot cannot be taken out at all. difficult question. At present, there are separate electric cookers in the market that can take out the middle pot. They set the heating device at the bottom of the shell, and then put the middle pot with a heat-conducting bottom layer into the shell for heating and cooking. For example, No. M492700 "Electric Pot The new type patent "Structural Improvement of the Middle Pot" is the invention of the separated middle pot. Please refer to Figure 1, which is a three-dimensional view of the conventional separated electric cooker. and the pot cover 12. Although the middle pot 11 can be taken out for easy cleaning, the bottom of the middle pot 11 is flat. When the middle pot 11 is placed in the outer shell 10, although the bottom can fit with the outer shell 10, the center is easily displaced and the middle pot 11 is flat. The pot is displaced, so that the heating cannot be uniform, so that the middle pot 11 must consume more heat energy to complete the purpose of cooking; and when the middle pot is placed in the shell, the electric pot device will be energized for heating and cooking, but if the position is shifted after being placed If the bottom is not fully fitted, the food cannot be cooked, which will lead to the misjudgment of the electric cooker to continue heating without power failure, which will not only easily damage the electric cooker heating device, but also cause safety concerns in use. The biggest criticism of the commercially available separate electric cooker to consumers.

Furthermore, in the commercially available separate type medium pot that can be taken out, the heating device is installed at the bottom of the outer shell. When in use, the heating device of the outer shell is used to heat the heat-conducting bottom of the middle pot to heat the inner pot for cooking. The thermal conductivity of the design is not good. The temperature of the outer casing is as high as 70 degrees Celsius during normal use. A little careless adult or accidental touch by a child will cause burns, and it is quite dangerous to use.

The inventor is specialized in the improvement, manufacture and sales of pots. He is well aware of the lack of traditional electric cookers and general separate electric cookers, so he has tried his best to think about the way of reform. With his professionalism and years of work experience, Coupled with continuous testing and improvement, the present invention was finally created.

The middle pot of the conventional separate electric cooker is easy to shift, so that the heating cannot be uniform, energy consumption is easy to be damaged, and it is quite inconvenient to use and obviously has major defects.

The present invention relates to a new structure of an electric cooker, in particular to a new structure of a separate electric cooker. The new structure of the electric cooker is mainly composed of a base, a pot body and a lid. There is a conductive convex column in the center of the base, and a control device is arranged inside the base. The control device has two base plates, the large base plate is used to control the heating device of the pot body, and the small base plate is used to select the operation mode; the pot system is combined by the outer shell and the middle pot The bottom layer of the middle pot is a heat conduction layer, combined with a heating device, and a conductive groove is arranged in the center; a clamping edge is formed on the side of the shell, and a hole is formed in the center. The pot cover is used to cover the pot body.

When assembling, first put the middle pot into the shell to form a pot body, so that the conductive groove of the middle pot is clamped to the hole in the center of the shell, and the pot body is placed on the base, so that the conductive protrusions of the base and the The conductive groove of the pot body is engaged, and the pot body can be fixed by the locking groove of the base and the locking edge of the pot body. Finally, the pot cover is closed on the pot body to complete the assembly. When in use, after the power switch is turned on, since the pot body is engaged with the base, there will be no offset and the heating device will be able to function properly. Effectively conduct direct heating and cooking; in addition, use the small base plate of the control device of the base to cooperate with the power switch to select the operation mode; and when the pot body is connected to the base, the large base plate controls the heating start of the heating device to protect the heating device and prolong its operation. The service life is quite practical and progressive.
