Description

A composite material inner pot and an electric heating cooking appliance having the same

technical field

The utility model relates to a composite material inner pot and an electric heating cooking appliance provided with it, which belongs to the field of household appliances.

Background technique

At present, the inner pots of pot products are generally aluminum inner pots or stainless steel inner pots. The aluminum inner pots are low in cost but poor in appearance, and the coating is easy to peel off after a long time of use. The stainless steel inner pot has a good glossy appearance and is durable in use, but the cost is high and the heating uniformity is poor.

Utility model content

The technical problem to be solved by the utility model is to provide a composite material inner pot and an electric heating cooking appliance with it. The inner pot is a composite inner pot made of aluminum alloy and stainless steel, which contains two layers, and the stainless steel layer is in turn from the inside to the outside. , aluminum alloy layer, or aluminum alloy layer, stainless steel layer, the stainless steel layer and the aluminum alloy layer are closely bonded. This solution combines the advantages of the stainless steel inner pot and the aluminum inner pot, with good heat transfer performance, lower cost, and better appearance. Better abrasion resistance.

The technical solution of the utility model to solve the above technical problems is as follows: a composite material inner pot, the inner pot is integrally formed by stretching an aluminum alloy plate and a stainless steel plate, after forming, the inner layer of the inner pot is an aluminum alloy layer, and the outer layer is stainless steel layer, or the inner layer of the inner pot is a stainless steel layer, the outer layer is an aluminum alloy layer, and the inner diameter of the inner pot is 10-500mm.

The beneficial effects of the utility model are: the utility model adopts a two-layer composite structure, which meets the good mechanical and thermal performance requirements of the inner pot. The aluminum alloy layer has high thermal conductivity, which improves the heat transfer speed of the inner pot; the stainless steel layer makes the appearance of the product more lustrous and beautiful, and at the same time increases the durability of the inner pot. The inner diameter of the inner pot is designed to be 10-500mm, so that the pressure-bearing performance of the inner pot is better, the arc structure of the bottom is not easy to deform, and the service life is longer, which effectively solves the problem of undercooked rice caused by the deformation of the inner pot.

On the basis of the above technical solutions, the utility model can also be improved as follows.

Further, the opening edge of the inner pot is provided with an arc-shaped pot rim outward.

The beneficial effect of adopting the above-mentioned further solution is that there is a pot edge structure, which is beneficial to take out the inner pot, and also makes the food at the edge of the inner pot heated evenly, which can effectively prevent the problem of undercooked food at the pot mouth.

Further, the outer diameter of the inner pot is 10-500 mm.

Furthermore, the height of the inner pot is 10-500mm.

Further, the bottom of the inner pot is recessed inward to form a structure with an arc-shaped longitudinal section.

The beneficial effect of adopting the above-mentioned further solution is that the bottom of the inner pot is sunken inward to form a structure with an arc-shaped longitudinal section, so that after the food at the bottom of the inner pot is heated, since the heating amount of the food in the central area of the bottom is less than that in the outer area of the bottom, the bottom can be effectively accelerated. The food in the central area (such as rice water mixture, or soup) flows from the high temperature in the center to the relatively low temperature area outside, so that the food at the bottom is heated more evenly and prevents the food at the bottom of the inner pot from being undercooked.

Furthermore, the radius of the circle where the arc-shaped structure at the bottom of the inner pot is located is 100-1000 mm.

The beneficial effect of adopting the above-mentioned further scheme is that by adopting an inner pot with an outer diameter of 10-500 mm along the edge of the inner pot, a height of the inner pot of 10-500 mm, and a radius of the circle where the arc structure of the inner pot bottom is located is 100-1000 mm. The pressure range of the electric pressure cooker is 50-90kpa, which can achieve effective pressure bearing. The arc of the bottom is not easy to deform after long-term use. The inner pot and the heating plate at the bottom fit better, and the service life is longer, which effectively solves the problem of cooking caused by the deformation of the inner pot. Unfamiliarity problem. Moreover, the radius of the circle where the arc-shaped structure at the bottom of the inner pot is 100-1000mm can make the internal objects roll and boil better, keep the temperature of the internal objects uniform, and prevent problems such as local browning and rawness.

The present invention also provides an electric heating cooking appliance, which contains the above-mentioned composite material inner pot.

On the basis of the above technical solutions, the utility model can also be improved as follows.

Further, the electric heating cooking appliance is an electric rice cooker or an electric pressure cooker.

The beneficial effect of the utility model is that the composite material inner pot of the new type can be used in all kinds of electric heating pot products, and the heating effect is good, and the cooked food is delicious without the phenomenon of raw or undercooked food.
