Electric steam boiler with function of maintaining one standard atmospheric pressure

Abstract

The invention discloses an electric steam boiler with a function of maintaining one standard atmospheric pressure. The electric steam boiler with the function of maintaining one standard atmospheric pressure comprises a box body, an inner container cavity, a steam constant pressure device which is capable of maintaining one standard atmospheric pressure, a water tank, a steam generator, a cooling channel and a control panel, wherein the inner container cavity and the water tank are both fixed inside the box body, and the steam constant pressure device is installed at a circular opening of the upper wall of the inner container cavity; the steam constant pressure device is communicated with the cooling channel, and the steam generator is installed at the opening of the lower wall of the inner container cavity. According to the electric steam boiler with the function of maintaining one standard atmospheric pressure, by arranging the steam constant pressure device which is capable of maintaining one standard atmospheric pressure on the inner container cavity of a normal pressure steam boiler, the pressure in the inner container cavity is maintained at one standard atmospheric pressure all the time and stably, and an electric steam box has the advantages of being simple in structure and low in cost, capable of solving the problem of food steaming at a low altitude area, and free of improving the design and manufacturing standards like a high-pressure steam furnace.

Description

Technical field [0001] The invention relates to the field of electric steam furnaces, in particular to an electric steam furnace with the function of maintaining 1 standard atmospheric pressure. Background technique [0002] Large-scale banquets, collective canteens, restaurants, etc. have a large amount of cooking, and only the electric steam oven with a large single steaming capacity can meet their needs. At present, the existing electric steam furnaces can be divided into constant pressure electric steam furnaces and high pressure electric steam furnaces according to the pressure of the inner chamber when working. The structure, shape and materials of the inner chamber of the normal pressure steam furnace Well-designed with limited pressure-bearing capacity, it can only withstand a working pressure slightly higher than 1 standard atmosphere (0.10142MPa). The inner tank cavity is always in communication with the local atmosphere. In low altitude areas, the boiling point of wate...

AI Technical Summary

Problems solved by technology

At present, the existing electric steam ovens can be divided into atmospheric pressure electric steam ovens and high pressure electric steam ovens according to the pressure level of the inner tank cavity. Carefully designed with limited pressure bearing capacity, it can only withstand a working pressure slightly higher than 1 standard atmospheric pressure (0.10142MPa). The inner tank cavity is always connected with the local atmosphere. In low altitude areas, the boiling point of water can reach up to Above 100°C, food can be cooked normally. It has the advantages of simple structure and relatively low manufacturing cost. ℃, so the temperature of cooking food is not enough. If the normal pressure electric steam oven is still used, the food cannot be steamed and sterilized. Using a high pressure electric steam oven can solve the above problems, but due to its high working pressure, the safety risk increases. The manufacturing cost of the inner tank cavity is greatly increased, thus increasing the manufacturing cost of the enterprise and the use cost of the user, and 1 standard atmospheric pressure of steamed food is enough

[0003] It was discovered that the existing patent "A Constant Pressure Closed-loop High-temperature Steamer" (application publication number CN 103300713 A) disclosed a constant-pressure closed-loop high-temperature steamer, which designed a pressure protection device on the steamer chamber , but does not give the internal structure of the pressure protection device, nor does it explain how much the internal pressure can be protected; the patent "Constant Pressure Valve" (application publication number CN106870785 A) discloses a constant pressure valve with a more complicated structure , there are different air inlet and outlet structures and methods, and three more valve chambers, which also achieve the effect of constant pressure

Therefore, at present, there is no low-cost accurate constant-voltage electric steam box with a simpler structure, suitable for high-altitude low-pressure areas, and capable of maintaining 1 standard atmospheric pressure.
