Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and particularly to a food processor with hot air heating. Background Art

[0002] Existing food processors include a mixing container and a base. A heating element is provided at the bottom of the mixing container. The mixing container is detachably mounted on the base. An electrical coupling connector is provided between the mixing container and the base, and the mixing container is electrically coupled to the base. The heating element heats the mixing container. To prevent the food in the mixing container from adhering to the inner bottom wall of the mixing container during heating, a non-stick coating, such as Teflon, is provided on the inner bottom wall of the mixing container. However, it is prone to peeling off and mixing into the food after long-term use, posing a risk of chemical contamination and affecting the safety of human consumption. The presence of the non-stick coating limits the use of cleaning agents, and bacteria are likely to breed after the coating wears. Therefore, it is necessary to develop a mixing container made of all-glass material. Summary of the Invention

The first valve seat 23 and the second valve seat 24 are fixedly connected by screws and / or buckles, and a sealing ring structure is provided between the first valve seat 23 and the second valve seat 24 to seal the installation gap between the first valve seat 23 and the second valve seat 24.

[0059] In this embodiment, a fixing member 25 and an elastically movable valve core 26 are provided in the first valve seat 23 and the second valve seat 24. A positioning ring is provided on the valve core 26, and a spring is provided between the positioning ring and the fixing member 25. When hot air enters the first valve seat 23 and presses the valve core 26, the valve core 26 opens the ventilation port of the fixing member 25, and the hot air is output along the second valve seat 24. When liquid enters the one-way valve 9 along the hot air pipe assembly 8, the valve core 26 always plays a blocking role to prevent the liquid from passing over the valve core 26 and entering the first valve seat 23.

[0060] In this embodiment, the first valve seat 23 is provided with a first one-way valve joint connected to the first hot air pipe 18, and the second valve seat 24 is provided with a second one-way valve joint connected to the second hot air pipe 19.

[0061] The pipe docking and coupling assembly 11 realizes the quick and sealed connection of the pipes between the stirring container 1 and the base 2, ensuring efficient transmission of hot air without leakage; the high-temperature resistant material (such as silica gel or polytetrafluoroethylene) can withstand long-term high-temperature air flow and avoid aging and deformation; the seal 14 further prevents hot air from leaking and improves the heating efficiency.
