Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and in particular relates to a double vacuum heat-insulating stewing appliance. Background Art

[0002] In the cooking process, simmering is a common practice. Simmering is to move the inner pot into the vacuum outer pot, cover the inner and outer pot lids, and let the food continue to simmer in the insulated pot using the residual heat. Currently, there are various stainless steel vacuum utensils on the market (including pots, cups, buckets, etc.). Even if there is an inner plug, the temperature will generally drop below 60°C after 12 hours, which can only keep the cooked food warm.

[0003] There are also stewing appliances with inner pots on the market, but the inner pots are mostly lighter aluminum non-stick pans or stainless steel pots. When the food is boiled, it is immediately placed in the vacuum insulation container. Due to the limited heat storage of the food and the inner pot, and the limited insulation effect of the outer vacuum container, many foods cannot reach a sufficient degree of softness. Summary of the invention

[0004] Aiming at the shortcomings of the existing stewing appliances that have insufficient heat preservation effect and poor cooking effect, the utility model provides a stewing appliance with double vacuum heat preservation, improves the heat preservation structure, and enhances the cooking effect.

[0005] To achieve the above purpose, the utility model adopts the following technical solution: a double vacuum insulation stewing device, the double vacuum insulation stewing device comprising:

[0009] The vacuum outer cover is fixed on the vacuum device body and has inner and outer walls, and a vacuum cavity is formed between the inner and outer walls;

[0010] Pot with lid, placed in the vacuum body.

[0011] The double vacuum insulation stewing device of the utility model comprises a vacuum body, an inner plug, a vacuum pumping component, a vacuum outer cover, and a pot with a cover. The pot with a cover is heated so that food and the inner pot are fully heated at the same time, and then immediately put into the vacuum body, plugged with the inner plug, and then artificially vacuumed using the vacuum pumping component to generate a second vacuum cavity inside the vacuum body. The sufficient energy storage of the pot with a cover and the double vacuum insulation enable the stewing device of the utility model to have the effect of long-term high-temperature stewing.

[0012] As an improvement, the opening of the vacuum body has an L-shaped cross section, the opening includes a radially inner bulge and a radially outer stopper, the upper end of the inner plug extends outward to form a limiting portion, and the limiting portion abuts against the bulge.

[0013] As an improvement, the inner plug has a U-shaped sealing portion, a sealing groove is provided on the outer side of the vertical wall of the sealing portion, a sealing ring is arranged in the sealing groove, and the vertical wall of the sealing portion and the raised portion radially compress the sealing ring.

[0014] As an improvement, the vacuum outer cover is threadedly connected to the vacuum body.

[0015] As an improvement, the opening portion includes an inner raised portion and an outer stop portion, the vacuum outer cover includes a threaded portion radially outside the lower end and an inclined portion located above the radial inner side of the threaded portion, and the threaded portion and the raised portion are threadedly connected.

[0016] As an improvement, the vacuum outer cover has inner and outer walls, and a vacuum cavity is formed between the inner and outer walls.

[0017] As an improvement, an anti-slip heat-insulating pad is also provided in the vacuum body.

[0021] The double vacuum insulation stewing device of the utility model has the beneficial effects of comprising a vacuum body, an inner plug, a vacuum pumping assembly, a vacuum outer cover, and a pot with a cover. The pot with a cover is heated so that food and the inner pot are fully heated at the same time, and are immediately placed in the vacuum body, the inner plug is plugged in, and then the vacuum pumping assembly is used to perform artificial vacuuming to generate a second vacuum cavity inside the vacuum body.
