Barbecue oven using PID temperature control

Abstract

The invention relates to the technical field of barbecue ovens, in particular to a barbecue oven using the PID temperature control. The invention adopts the following technical scheme: the barbecue oven comprises a barbecue oven body and a heating device arranged in the barbecue oven, a barbecue grill is arranged above the heating device, a PID temperature controller is arranged on the barbecue oven body, an electric heating plate is adopted as the heating device, a first temperature sensor is arranged on the upper surface of the heating device, and the output end of the PID temperature controller is connected to the heating device to be controlled. The intelligent barbecue oven has the advantages that the PID temperature controller is used for controlling the electric heating device of the barbecue oven. Meanwhile, the first temperature sensor is used in cooperation for feeding back the actual temperature of the electric heating device, and therefore the quick and accurate control over the temperature of the barbecue oven is improved, and the barbecue quality is improved; meanwhile, a second temperature sensor on the barbecue grill is matched, the actual barbecue temperature is further adjusted, and the barbecue quality is further improved.

Description

technical field [0001] The invention relates to the technical field of barbecue ovens, in particular to a barbecue oven using PID temperature control. Background technique [0002] Barbecue oven is a kind of barbecue equipment used for grilling food. The traditional barbecue oven uses charcoal for barbecue. Because charcoal will produce thick smoke during the burning process and there is a big safety hazard, it is gradually being used as natural gas or liquefied petroleum. Gas grills with gas as fuel or electric grills with electricity as the heating method are replaced; the current electric grills simply use linear controllers such as sliding rheostats to connect to electric heating devices for temperature adjustment. There is a large time delay when the temperature rises, especially the heat conduction plate is generally wrapped around the electric heating device, so there is a large time delay. At the same time, there is also a time delay when the heat from the electric h...

[0002] Barbecue oven is a kind of barbecue equipment used for grilling food. The traditional barbecue oven uses charcoal for barbecue. Because charcoal will produce thick smoke during the burning process and there is a big safety hazard, it is gradually being used as natural gas or liquefied petroleum. Gas grills with gas as fuel or electric grills with electricity as the heating method are replaced; the current electric grills simply use linear controllers such as sliding rheostats to connect to electric heating devices for temperature adjustment. There is a large time delay when the temperature rises, especially the heat conduction plate is generally wrapped around the electric heating device, so there is a large time delay. At the same time, there is also a time delay when the heat from the electric heating device is transferred to the grilled food. Therefore, simply using a linear controller to control the electric heating device will cause a serious delay in heating time, which will affect the quality of barbecue
