Description

Technical Field

[0001] The utility model relates to the field of household appliances, in particular to a food processor with a double-layer bottom shell. Background Art

[0002] The general structure of an existing food processor includes a main unit and a cup body. A heating plate and a chopping mechanism are provided on the top of the main unit, and a driving motor for driving the chopping mechanism to rotate is provided inside the main unit. In order to achieve heat dissipation, it is usually necessary to set an air inlet and an air outlet at the bottom of the main unit. A fan is provided in the main unit for driving air to enter the main unit from the air inlet and be discharged from the air outlet to take away heat. Due to the provision of the air inlet and the air outlet, in order to avoid water ingress, the existing main unit cannot be directly rinsed, so that food residues on the heating plate and the chopping mechanism are often not thoroughly cleaned or are difficult to clean, thereby reducing the user experience.

[0003] To solve the above problems, technicians have designed a waterproof cover for food processors. The waterproof cover is placed on the bottom of the main unit to close the air inlet and outlet on the main unit to prevent water from seeping from the bottom of the main unit. When the food processor needs to be used, the waterproof cover is removed. Although this solution can prevent water from seeping from the bottom of the main unit, it requires repeated removal of the waterproof cover, which is inconvenient to use and not conducive to the storage of the waterproof cover. Repeated removal of the waterproof cover can easily cause it to deform and damage. Summary of the invention

[0004] The invention of the utility model aims to solve the problem that the waterproof cover of the existing food processor needs to be repeatedly disassembled, and to provide a food processor with a double-layer bottom shell.

[0005] In order to achieve the above invention objectives, the utility model adopts the following technical solutions:

[0007] The food processor of the utility model has an internal sealing structure including a movable stopper and a fixed stopper.

When cleaning is required, the first air inlet and the second air outlet are closed by the movable stopper to prevent water from entering the inner cavity of the main unit through the first air inlet and the second air outlet. Due to the setting of the internal sealing structure, the motor cover and the bottom of the outer shell are separated and have a height difference. Even if there are small water droplets that penetrate into the inner cavity of the main unit through the gap between the first air inlet and the second air outlet and the movable stopper, they are blocked outside the fixed stopper.

[0009] Furthermore, a retaining wall is arranged around the inner periphery of the air outlet, and the inner periphery of the retaining wall forms a first air outlet. In this solution, the retaining wall can prevent water from flowing into the motor cover along the inner wall of the air outlet after water enters the inner cavity of the food processor.

[0010] Furthermore, at least two groups of fixing structures are evenly distributed between the inner peripheral wall of the shell and the sealing portion.

[0012] Furthermore, the movable stopper includes a stopper body and a trigger mechanism, the stopper body has a first position and a second position, one end of the trigger mechanism protrudes outward from the outer wall of the host, and when the trigger mechanism is triggered, it drives the stopper body to switch from the first position to the second position, so that the stopper body opens the first air inlet and the second air outlet. The movable stopper of this solution realizes the opening and closing of the air hole by switching positions, and the operation is simple. Furthermore, the inner sealing structure includes an elastic reset mechanism, which is connected between the stopper body and the outer shell, and provides a reset elastic force for the stopper body, so that the stopper body closes the first air inlet and the second air outlet.

[0013] Furthermore, the inner sealing structure includes a limiting mechanism, and the movable stopper switches between the first position and the second position by any one of translation or axial displacement. The limiting mechanism is located on the upper side of the stopper body to limit the longitudinal movement of the stopper body.
