Description

Pot washer and electric rice cooker using the same

【Technical field】

The utility model relates to an electric cooker, in particular to a pot washer used in the electric cooker.

【technical background】

The pot lid of the existing electric rice cooker is sealed with the inner pot by the pot gasket, and the cross-section of the mating part of the pot gasket and the inner pot is generally in the shape of "V" or "U". The structure of this pot gasket in the unclosed state of the pot cover is shown in Figure 7, and the structure in the closed state of the pot cover is shown in Figure 8.

After keeping the rice warm for a period of time, due to the large temperature difference between the inside of the pot and the outside of the pot, the pot gasket is far away from the heat preservation and heating device and is relatively weak, so it is very easy to be affected by the external low temperature side and cause the pot to The temperature at the gasket is relatively low. When the water vapor in the pot meets the lower temperature pot gasket, it will condense into water droplets when it encounters condensation. When the lid is opened, more water droplets will flow down and drip onto the upper frame and lid of the rice cooker, causing troubles in use. This phenomenon of condensing into water drops not only causes inconvenience to the user, but also aggravates the reduction of the temperature in the pot, which also has a certain impact on the heat preservation performance of the electric cooker.

In order to solve the above problems, some electric cookers are equipped with water receiving boxes. Although this measure prevents the water drops from dripping onto the upper frame and the pot cover of the electric cooker, it still produces water drops itself, but the produced water drops will Connecting to the water receiving box not only requires adding a water-saving box, which increases the cost, but also does not fundamentally solve the problem of condensation forming water droplets.

The purpose of this utility model is to solve the problems existing in the prior art, and propose a pot washer and an electric cooker using the pot washer, which can reduce the heat conduction between the low-temperature side outside the pot and the inside of the pot, and prevent water vapor from condensing into water beads, so as to facilitate the use of users, and improve the heat preservation effect of the rice cooker.

In order to achieve the above purpose, the utility model patent proposes a pot gasket, which includes a riveted part that can be embedded in the pot cover, and a deformation part connected to the riveted part. The interior of the deformation part forms a gasket inner cavity, and also includes a sealing part. The sealing part is arranged at the opening of the inner cavity of the gasket, and seals the inner cavity of the gasket when the deformation part is in a deformed state, forming a closed space isolated from the outside world.

Preferably, the front end of the sealing portion is connected to the rear end of the deformation portion, and when the deformation portion is in a deformed state, the rear end of the sealing portion abuts against the joint between the riveting portion and the deformation portion or directly against the deformation portion.

Preferably, the front end of the sealing portion is connected to the rear end of the deformation portion, and when the deformation portion is in a deformed state, the rear end of the sealing portion abuts against the inner surface of the pot cover on which the riveting portion is installed.

Preferably, the front end of the sealing part is connected to the joint between the riveting part and the deforming part, and when the deforming part is in a deformed state, the rear end of the sealing part abuts against the deforming part.

Preferably, the front end of the sealing part is connected to the joint between the riveting part and the deforming part, and when the deforming part is in a deformed state, the rear end of the sealing part abuts against the inner surface of the inner pot of the electric rice cooker.

Preferably, the thickness of the sealing part gradually becomes thinner from the front end to the rear end.

In order to achieve the above purpose, the utility model patent proposes an electric rice cooker, which includes an inner pot and a pot cover, the pot cover covers the opening of the inner pot, and the aforementioned pot washer is embedded in the pot cover.

Beneficial effects of the utility model patent: the utility model adds a sealing part to the pot gasket, so that when the pot cover is closed, a sealing layer is formed in the gasket inner cavity of the pot gasket. The heat conduction between the outer low-temperature side and the inside of the pot improves the heat preservation effect, and no condensation will be formed in the inner cavity of the gasket. dew. It fundamentally solves the condensation problem of the rice cooker after a period of heat preservation. Additional components such as a water receiving box are not required, the structure is greatly simplified, and the cost is reduced.
