Electrical heating pressure appliance capable of controlling pressure through displacement caused by deformation of elastic element

Abstract

The invention discloses an electrical heating pressure appliance capable of controlling pressure through displacement caused by deformation of an elastic element. The appliance comprises a container cover, a seal ring, a container, an outer pot, a heating disk, the elastic element and a power supply switch. The appliance is characterized in that the elastic element is sleeved on the stand bar of the heating disk, the heating disk, the elastic element and the outer pot are fixed through bolts, and the heating disk is flexibly connected with the outer pot; the lower bottom of an inner pot is stuck to the cambered surface of the heating disk, the cover teeth of a pot cover are buckled with the button teeth of the outer pot, and the seal ring is sleeved on the container cover and respectively adhered to the container cover and the container; and the power supply switch is fixed on the side face of the outer pot through a bracket, and the heating disk and the power supply are connected in series on an alternative current power supply. The electrical heating pressure appliance disclosed by the invention is suitable for an electric pressure cooker, a pressure soymilk machine, a pressure coffee machine and other appliances controlled by using the elastic elements.

Description

technical field [0001] The invention relates to an electric heating pressure appliance, in particular to an electric heating pressure appliance controlled by pressure, such as an electric pressure cooker, a pressure soybean milk machine and a pressure coffee machine. Background technique [0002] At present, there are mainly three ways to control the pressure of electric heating pressure appliances such as electric pressure cooker, pressure soybean milk machine and pressure coffee machine: [0003] 1. Most of the products on the market adopt the "Kuang" type structure (refer to Chinese patent CN1060020A), the pressure switch is installed on the outer pot wall, and the bottom of the outer pot adopts "plate" type spring, "U" shaped spring, " Bridge" shaped spring, "V" shaped spring. The elastic deformation of the above springs is small, and the manufacturing process is complicated and the cost is high; there are abnormal noises during normal use (in order to solve this proble...

AI Technical Summary

Problems solved by technology

The processing and manufacturing precision of key components such as the inner pot and the outer pot is very high, which increases the difficulty and complexity of the parts in the production and processing process, and the high scrap rate increases the manufacturing cost of the product virtually. It is easy to cause air leakage due to the deformation of parts and the reduction of precision, and there are great unstable factors in its pressure control

[0005] 3. The temperature control method is to use the thermistor to detect the temperature in the container, and then convert it into pressure through the chip, and the pressure control error is large

This kind of appliance can only be made into a conjoined structure, not a split structure. The market space of the product line is too small to meet the needs of the market at the time of design.
