Fixing device for glass liner and shell of microwave oven heat preservation cooking pot

Abstract

The invention provides a fixing device of a glass inner container and a shell of a microwave oven heat preservation cooker. The device comprises a shell, the shell includes an upper shell and a lowershell, a glass inner container is arranged in the shell, a filling cavity is formed between the glass inner container and the shell, and an upper cover is arranged on the upper shell; the device is characterized in that a fixing ring is mounted in the filling cavity, elastic pieces are arranged in the fixing ring, jacking columns are arranged on the elastic pieces, a limiting groove is formed in the periphery of the fixing ring, protruding ribs are arranged on the inner wall of the upper shell, the protruding ribs are matched with the limiting groove, a flanging structure is arranged on the opening of the glass inner container, the jacking columns of the elastic pieces are in contact with the bottom surface of the flanging structure, a hold-down ring is arranged on the opening of the uppershell, a sealing ring is arranged below the hold-down ring, and the lower surface of the sealing ring is in contact with the upper surface of the flanging structure of the glass inner container.

Description

technical field [0001] The invention relates to a heat-preserving cooking pot for a microwave oven, in particular to a fixing device for a glass liner and a casing of a heat-retaining cooking pot for a microwave oven. Background technique [0002] The heat preservation container mainly has an outer shell, an inner tank inside the outer shell, an insulating layer between the outer shell and the inner tank, and a cover on the outer shell. If the inner tank is made of stainless steel, stainless steel can be used as an insert during processing. Finally, inject polyurethane foaming agent between the shell and the inner tank as the insulation layer, and the processing is more labor-saving, but the thermal insulation container of the stainless steel inner tank cannot be heated in a microwave oven, so the inventor adopts a glass inner tank, so that the thermal insulation container has With the function of microwave oven cooking, after using the glass liner, because the glass materia...

Problems solved by technology

[0002] The heat preservation container mainly has an outer shell, an inner tank inside the outer shell, an insulating layer between the outer shell and the inner tank, and a cover on the outer shell. If the inner tank is made of stainless steel, stainless steel can be used as an insert during processing. Finally, inject polyurethane foaming agent between the shell and the inner tank as the insulation layer, and the processing is more labor-saving, but the thermal insulation container of the stainless steel inner tank cannot be heated in a microwave oven, so the inventor adopts a glass inner tank, so that the thermal insulation container has With the function of microwave oven cooking, after using the glass liner, because the glass material is afraid of being squeezed and easily broken, it cannot be used as an insert during processing. Therefore, before filling the polyurethane foaming agent between the shell and the glass liner, the shell needs to be Fixing with the glass liner, for example, the inventor designed a sealing mechanism for the connection port of the glass liner of the thermal insulation rice bucket, and its patent number is 2015102313626. The sealing mechanism mainly uses the support ribs and the connection port. The structure is complex, the processing mold is many, the cost is high, the installation is troublesome, the manufacturing is difficult, etc.
