One-key automatic steaming cabinet control system

Abstract

The invention relates to a one-key automatic steaming cabinet control system, belonging to the field of kitchen equipment control. A power supply is connected with a heating pipe through a main contact on a contactor. The one-key automatic steaming cabinet control system is characterized by comprising a transformer, a time relay, a temperature controller and a button switch, the primary side of the transformer is connected with the power supply, the secondary side of the transformer is connected with the input end of the time relay through a serial button switch, the output end of the time relay is connected with the control end of the contactor through the temperature controller connected in series, and the signal input end of the temperature controller is connected with a temperature sensor. High-voltage power can be transformed by the transformer into low-voltage power for control, the time relay outputs the voltage to control actuation of the contactor, the heating pipe works for steaming, the working time of the electric heating pipe is controlled by the time relay, the food temperature is controlled by the temperature controller, the low-voltage short-range control is realized, the operating time is accurate the operation is simple, the water and power are saved, the high-voltage remote control of the conventional steaming cabinet is perfected, and the defects of irregular operating time and dry-burning of the electric heating pipe as a result of water shortage can be overcome.

Description

technical field [0001] The invention provides a one-button automatic rice steaming cabinet control system, which belongs to the field of kitchen equipment control. Background technique [0002] The existing rice steaming cabinet control system generally adopts a power cord to directly access the power supply box or adopts microcomputer control and the like. [0003] Chinese patent ZL 200820022956.1 discloses a fully automatic microcomputer-controlled rice steamer. It has a cabinet, a door is installed on the cabinet, the lower part of the cabinet is a water tank, a control panel is arranged on the door, a microcomputer controller is arranged on the control panel, and the input terminal of the microcomputer controller is connected with the button electric connection, the output end of the microcomputer controller is electrically connected to the input end of the heating control module, the output end of the heating control module is electrically connected to the AC contactor...

AI Technical Summary

Problems solved by technology

[0004] At present, the disadvantages of this technology are: first, the microcomputer controller is installed on the door body, and the inside of the door body can reach 90°C during the steaming process, while the working environment temperature of the general microcomputer cannot exceed 60°C, which greatly shortens the use of the microcomputer Second, the control line connected to the microcomputer is connected to the control terminal through the door hinge. When the door hinge is repeatedly closed, the control line is easily broken, forming an open circuit, and it is not convenient for maintenance; , the general user group is not proficient in the use of microcomputers, which may easily cause microcomputer program disorder; fourth, because the heating tube generally has a large power and uses a relatively large current, experiments have shown that the contacts used in microcomputers are easy to sinter and cause short circuits; fifth, Generally, the transformers of microcomputer controllers are installed here. Once damp or water enters, not only the photoelectric components will be damaged, but the input power of the transformer will also form a short circuit, causing danger; Shorter and higher maintenance costs; microcomputer controllers with higher prices are generally not adopted; Sixth, through market research, the market share of steamed rice cabinets equipped with microcomputer controllers is extremely small, and the repair rate reported by sellers is extremely high
