Box door auxiliary closing device and method of steam cabinet and steam cabinet

Abstract

The invention discloses a box door auxiliary closing device of a steam cabinet. The box door auxiliary closing device comprises a box door state detector, a timer, at least one exhaust valve and a central controller, wherein the box door state detector sends out a door closing signal when detecting that a box door has the closing action; the timer sends out an ending signal after finishing the timing operation; the at least one exhaust valve is arranged in a box in a penetration manner; the central controller is electrically connected with the box door state detector, the timer and the at least one exhaust valve respectively, controls the at least one exhaust valve to be opened according to the door closing signal, and simultaneously starts the timer, and after the timer finishes the timing operation, the central controller controls the at least one exhaust valve to be closed according to the ending signal. The at least one exhaust valve is automatically opened when a user closes the box door, so that the air pressure inside the box is reduced, further, the problem that the box door is pushed open due to overhigh air pressure is avoided, therefore, an auxiliary effect is achieved for the box door closing operation, thus the box door is closed easily, and time and labor are saved.

Description

technical field [0001] The invention relates to a steamer, in particular to an auxiliary closing device for a door of the steamer, an auxiliary closing method and the steamer. Background technique [0002] In the catering industry, steaming cabinets are widely used. At the same time, steaming cabinets account for the largest proportion of energy consumption. The airtight method can save energy very obviously, even reaching more than 50%. For the structure of the existing steam cabinet, please refer to the description of the invention patent application with the application number 201310724212.X and the title "An Intelligent Control Device and Method for the Steam Cabinet". The steam cabinet includes a steam generating device and several steam boxes. Connected with the steam generating device, the body of the steamer is equipped with a central controller, a display connected to the central controller, a timing control module, and several button modules. The steamer is equippe...

Problems solved by technology

However, when the internal temperature of the steamer cabinet is high, if the door is closed, the air with a lower temperature outside will be shut into the cabinet, and the air will expand rapidly when heated, which will increase the internal pressure of the cabinet. Especially at the last moment, the typical phenomenon is that the internal pressure is too high and the door is pushed open, which makes it difficult to close the door, especially when the internal temperature of the cabinet is high, and the user needs to wait for the temperature in the cabinet to drop. Closing the box door wastes time and is difficult to use
