Embodiment Construction

[0026] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0027] First, introduce and explain the nouns involved in this application:

[0028] PID: P is the abbreviation of Proportional, meaning proportional; I is the abbreviation of Integral, meaning integral; D is the abbreviation of Differential, meaning differential. The PID control algorithm is a control algorithm that combines the three links of proportional, integral and differential. It is the most mature and widely used control algorithm in continuous systems. clear occasions. Both the actual operation experience and the theoretical analysis show that when using this c...

Abstract

The invention relates to cooking equipment and a temperature control method thereof. The method comprises the following steps: determining a preset cooking temperature; if the preset cooking temperature is larger than the first temperature and not larger than the second temperature, a heating pipe is turned on, and when it is determined that the cavity temperature reaches the preheating temperature, the heating pipe is turned off, and an evaporator is turned on; when the evaporator reaches the evaporation temperature, the evaporator is controlled to conduct cooking preheating, so that the temperature of the cavity is increased to the cooking temperature; controlling the evaporator and the heating pipe to be switched on and off simultaneously through proportional-integral-derivative so as to keep the temperature of the cavity at the cooking temperature; if the preset cooking temperature is not smaller than the third temperature and not larger than the first temperature, the evaporator is started, and when the evaporator reaches the evaporation temperature, the evaporator and the heating pipe are controlled to be switched on and off at the same time through proportional-integral-derivative, so that the temperature of the cavity is increased and kept to the cooking temperature. According to the embodiment of the invention, the actual temperature in the cooking equipment is the cooking temperature by improving the temperature control capability.

Description

technical field [0001] The present application relates to the technical field of cooking equipment temperature control methods, in particular to a cooking equipment and a temperature control method thereof. Background technique [0002] At present, cooking equipment (for example, a steamer and a steaming and roasting machine) have a low-temperature steaming function of the cooking equipment, that is, steaming and roasting are performed simultaneously at 100 degrees Celsius lower than the boiling point of water, for example, 50 degrees Celsius to 90 degrees Celsius; wherein, cooking The equipment includes an evaporator and a cavity for preventing and cooking ingredients; the evaporator is used to generate water vapor, and the generated water vapor is used to pass into the cavity to realize the steaming function of the cooking equipment; a heating tube is arranged in the cavity for use It is used to increase the temperature in the cavity to realize the roasting function of the...
