Description

Insulation cover and electric pressure cooker with the same

technical field

The utility model belongs to the field of small kitchen appliances, in particular to a thermal insulation cover and an electric pressure cooker with the thermal insulation cover.

Background technique

Electric rice cooker, electric pressure cooker, electric stew pot, automatic electric frying pan etc. are daily electric cooking utensils widely used by people, and people's daily life has been more and more inseparable from these electric cooking utensils. The use of resources is involved in the manufacture and use of electric cookers. In order to save resources, electric cookers should be as simple in structure, stable and reliable as possible, and save energy while meeting functional requirements. Take the electric pressure cooker as an example. The electric pressure cooker includes a top cover and a pot body. The top cover has a detachable cover or a heat preservation board. There are different configurations according to the needs. In order to meet the needs of cooking good rice, the top cover of the electric pressure cooker is generally equipped with a heat preservation The upper insulation of ordinary electric pressure cookers on the market is usually to add a thermal insulation board inside the upper cover, the heating element heats the thermal insulation board, and the heat after the thermal insulation board heats up is transferred to the detachable cover above the pot mouth or the inner pot cover through heat conduction. To achieve the heat preservation effect, but there is usually a gap between the heat preservation board and the detachable cover or the inner pot cover, and the heat preservation effect is not good.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides a heat preservation cover with simplified structure and energy saving and an electric pressure cooker with the heat preservation cover.

In order to achieve the above purpose, the utility model adopts the following technical solutions: the heat preservation cover includes an upper cover, an inner cover detachably connected below the upper cover and a heating element, and an elastic element is arranged between the upper cover and the inner cover. One end is connected to the inner surface of the upper cover, and the other end of the elastic element pushes the heating element against the inner surface of the inner cover. The arrangement of the elastic element makes the heating element fully contact with the surface of the inner cover, the heat conduction efficiency is higher, and the insulation board is removed, so the structure is simplified.

Preferably, the heating element is a PTC heating element. The PTC heating element has a smaller volume, faster heating speed, and higher thermal efficiency.

Preferably, a heat insulation pad is provided between the upper cover and the elastic element. When the temperature of the heating element exceeds 130°C, the elastic element will conduct the high temperature to the upper cover, and the setting of the heat insulation pad avoids damage to the upper cover made of plastic material, and avoids the risk of burns caused by the user touching the upper cover.

Preferably, the elastic element is a spring.

The utility model also provides an electric pressure cooker provided with the aforementioned heat preservation cover.

To sum up, the utility model has the following advantages: the utility model removes the structure of the heat preservation board and simplifies the structure, but at the same time, the heating element with a smaller volume is in full contact with the inner cover, and the high heat transfer efficiency ensures a good heat preservation effect. Energy is saved and the purpose of energy saving and consumption reduction is achieved.

Detailed ways

In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the utility model. Obviously, the described The embodiments are only some of the embodiments of the present utility model, but not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

The heat preservation cover in this embodiment can be set on but not limited to the electric pressure cooker. The following will take setting the heat preservation cover on the electric pressure cooker as an example for specific description:

As shown in Fig. 1, Fig. 2 and Fig. 3, the heat preservation cover includes a loam cake 1 and an inner lid 2 arranged below the loam cake 1, and the loam cake 1 and the inner lid 2 are detachably connected, and in this embodiment, it is a buckle Then, the upper cover 1 is fixedly connected with a spring 3 close to the inner surface of the electric pressure cooker body, and the other end of the spring 3 is connected with a heating element 4. In this embodiment, a PTC heating element with a small volume and high heating effect is selected as the heating element. To prevent the heat generated by the heating element 4 from being transmitted to the upper cover 1 through the spring 3 when the electric pressure cooker is in operation, thereby causing damage to the upper cover 1 made of plastic material or the risk of scalding the user, a partition can be provided between the upper cover 1 and the spring 3 heat pad. When the inner cover 2 is assembled on the upper cover 1, the inner cover 2 provides the PTC heating element with a pressure to shrink toward the upper cover 1 side, and the reaction force of the spring 3 exerts a pressure on the other side of the PTC heating element toward the inner cover 2. side movement pressure, so that the PTC heating element is in full contact with the inner cover 2 and fits closely, reducing the loss of heat in the heat conduction process and ensuring that the heat generated by the PTC heating element is transferred to the inner cover 2 to the maximum extent, so the inner cover 2 from The top provides heat to the food in the electric pressure cooker to keep warm.

The above-mentioned specific embodiments are used to explain the utility model, rather than to limit the utility model. Within the spirit of the utility model and the scope of protection of the claims, any modifications and changes made to the utility model fall into the scope of the utility model. scope of protection.
