Description

Food preparation machine with good thermal safety

Technical Field

The utility model belongs to the technical field of household cooking appliances, and particularly relates to a food processing machine with good thermal safety.

Background

With the improvement of living standard, various food processing machines suitable for home use, such as electric ovens, electric chafing dishes, baking machines (electric baking pans), wall breaking machines, etc., are emerging. The wall breaking machine is a new star in a food processing machine, and the existing wall breaking machine generally comprises a base, a knife assembly for crushing food materials, a stirring cup body arranged on the base, and a heating disc assembly arranged at the bottom of the cup body. When edible material needs to be processed, the food material can be placed into the cup body and the program is started, the stirring knife in the knife assembly rotates at a high speed at the moment, and then the food material is crushed to a broken cell wall state with broken cell walls, so that the human body can absorb nutrition of the food material, the processed slurry can be output outwards through the slurry outlet, and at the moment, only one slurry receiving cup needs to be placed at the slurry outlet to receive the flowing slurry.

When soybeans are required to be made into soybean milk or similar procedures requiring heating and cooking are carried out, the heating plate in the heating plate component is electrified to generate heat, so that food materials such as soybean milk in the boiled cup body are heated.

In order to make things convenient for manufacturing and assembly, the cup part of current broken wall machine adopts the overall structure that can not unpick and wash to cause the user to be difficult for wasing the big and unclean defect of washing degree of difficulty in the gap between cup and the knife tackle spare and the dish bottom that generates heat when wasing.

Therefore, the cup body part of the wall breaking machine is designed into a detachable and washable split structure by people, and the structure is as follows: the cup body assembly comprises a cup body with the bottom opened and a heating disc assembly arranged at the opening at the bottom of the cup body, namely, the heating disc assembly plays a role in heating slurry and food materials in the cup body on one hand and is equivalent to the bottom of the cup body on the other hand. When the program operation is finished, the detachable cup body is independently cleaned. In order to facilitate cleaning, the conventional heating tray assembly generally comprises a sealed shell and an electric heating tube arranged in the shell, so that food materials, slurry and the like are prevented from contacting the electric heating tube when the heating tray assembly is used, particularly, cleaning water can be prevented from permeating and contacting the electric heating tube when the heating tray assembly is cleaned, and the safety of the heating tray is improved. Meanwhile, the sealed shell can effectively isolate the electric heating tube from transferring heat into the host machine so as to ensure the safety of the host machine.

However, the heating plate assembly with such a structure has the following technical defects: when soybeans are required to be made into soybean milk or similar procedures requiring heating and cooking are carried out, the electric heating tube in the heating disc component needs to be electrified to generate heat, and at the moment, the gas in the sealed shell rises due to the rise of temperature, so that the gas pressure rises. It can be understood that when the program is normally operated, the cup body is filled with a large amount of liquid such as slurry, and the temperature of the heating plate component is only slightly higher than the temperature (100 ℃) of the liquid in the cup body. When the heating plate works for a long time or a user forgets to shut down to cause liquid such as slurry in the cup body to be dried, the temperature of the heating plate assembly can rise linearly and is far higher than 100 ℃, accordingly, the air pressure in the sealed shell can also far exceed a set value, and therefore the shell has potential safety hazards such as cracking and even explosion.

As mentioned above, when the temperature of the heating plate assembly rises, the air pressure in the heat insulation cavity rises, and then potential safety hazards and risks are generated. Therefore, the heating plate assembly is provided with the pressure relief device, when the actual air pressure P in the heat insulation cavity is greater than the set highest pressure P, the pressure relief device acts to release the air pressure in the heat insulation cavity, and then the air pressure in the heat insulation cavity is ensured to be maintained below the set highest pressure P, so that the thermal safety performance of the heating plate assembly is greatly improved, and the safe use of a user is ensured.

When the air pressure in the heat insulation cavity is higher than the set highest pressure, the air pressure pushes the valve core to overcome the elasticity of the elastic element and move outwards, the valve cap at the moment leaves the valve cavity, and the high-pressure air in the heat insulation cavity can be discharged outwards through the fit clearance between the valve core and the valve cavity. It can be understood that the valve core is movably connected with the valve cavity, that is, a fit clearance is arranged between the valve core and the valve cavity, and the sealing of the pressure relief device is realized by tightly closing and plugging the valve cavity by the valve cap, so that the fit clearance can be properly increased to facilitate the leakage of high-pressure gas, and the sealing performance of the pressure relief device cannot be influenced.
