Embodiment 1

[0035] Such as figure 1 , 2, 3, 4, 5, 6, 7, 8, and 9 show the double control system of the steam cabinet, the main system includes the power supply circuit, the single chip microcomputer port control circuit, the solenoid valve drive circuit, the proportional valve drive circuit, the ignition drive circuit, the DC DC brushless motor drive circuit, steam pump drive circuit, temperature / gear / gate control detection circuit, flame detection circuit, water level detection circuit, steam pump drive circuit and mode selection drive circuit, the proportional valve drive circuit drives the connected ratio The valve cooperates with the DC brushless motor driven and connected to the DC brushless motor drive circuit to fully premix the gas and air and then supply the gas to the burner. The electrical box also includes a controller 25 and a solenoid valve B32 for manually adjusting the flow rate. , the backup system includes a controller 25, a single-speed fan 9, a solenoid valve B32 and ...

Embodiment 2

[0075]The difference between this embodiment and Embodiment 1 is the mode selection drive circuit. The mode selection drive circuit has four toggle switches, which can be combined into multiple modes. Each mode can choose a different gear switch type, manual or automatic mode, Different program settings are suitable for different devices.

Embodiment 3

[0077] The difference between this embodiment and Embodiment 1 is the gate control detection circuit. According to the signal sent by the gate control switch that several doors are in use, the large, medium and small fires are automatically selected. At the beginning, when the temperature is low, the fire is burned at the maximum , when the temperature reaches a certain level, the firepower is controlled by the number of doors used, and the specific parameters can be set by the program.

Abstract

The invention relates to the kitchen equipment technology field and particularly relates to a dual-control system of a steam cabinet. The dual-control system of the steam cabinet comprises a power supply circuit, a single-chip micro-computer port control circuit, a solenoid valve driving circuit, a proportional valve driving circuit, an ignition driving circuit, a DC brushless motor driving circuit, a steam pump driving circuit, a temperature / gear / gated detection circuit, a flame detection circuit, a water level detection circuit, a steam pump driving circuit and a mode selection driving circuit; a proportional valve which is in driving connection with the proportional valve driving circuit is in coordinated cooperation with a DC brushless motor which is in driving connection with the DC brushless motor driving circuit in order to fully pre-mix the gas and the air and then supply the mixed gas to a burner; a standby system comprises a controller, a single-speed draught fan and a solenoid valve B; a solenoid A of a master system and the solenoid valve B of the standby system are communicated with the burner through a tee. The dual-control system of the steam cabinet is advantageous in that an air flow can only be regulated through regulating the solenoid valve by hand, which is safe and reliable and greatly improves safety.

Description

technical field [0001] The invention relates to the technical field of kitchen equipment, in particular to a dual control system for a steaming cabinet. Background technique [0002] Steaming cabinets include electric steaming cabinets and gas steaming cabinets. Gas steaming cabinets are more popular with users because of the use of gas and taste. It is necessary to consider energy consumption and other issues, as well as reduce labor costs, to achieve intelligent adjustment, to avoid human negligence, resulting in water shortage of equipment, damage caused by dry burning of water, gas leakage caused by flame extinguishing, and carbon monoxide poisoning caused by insufficient combustion. There are great safety hazards in the use of such accidents, so precise system control is required to ensure the safety of the steps. There are preventive measures, and it can also control and adjust, improve efficiency, reduce energy consumption, and improve benefits. Not only that, when a ...
