Modifications to the embodiments of the invention or equivalent substitutions of parts of technical features without departing from the spirit of the invention are intended to be covered by the scope of the claims of the invention.
Referring to fig. 1, the present invention provides a method for controlling a temperature of a cooking apparatus, comprising the following steps:
s1: starting the cooking equipment;
s2: judging whether the temperature detected by a probe used for detecting the temperature of a cooking cavity in the cooking cavity of the cooking equipment in the cooking equipment reaches a preset temperature T or not, if so, entering S3, and if not, executing a preheating step by the cooking equipment;
s3: the cooking cavity enters a constant temperature stage, and the heating element is closed;
s4: the probe obtains the temperature t for a plurality of times at intervals of preset time n 、t n-1 、t n-2 …t n-m Judging whether t is present n <t n-1 <t n-2 …<t n-m If t is n <t n-1 <t n-2 …<t n-m Then, go to S5 if not t n <t n-1 <t n-2 …<t n-m If so, entering S6;
s5: judging whether the temperature detected by the probe is less than the preset temperature T + T 1 If the temperature detected by the probe is less than the preset temperature T + T 1 Then the heating element is opened, if the temperature detected by the probe is more than or equal to the preset temperature T + T 1 If yes, repeating S5;
s6: acquiring the temperature t detected by the probe for a plurality of times at preset intervals n 、t n-1 、t n-2 …t n-m Judging whether t is present n >t n-1 >t n-2 …>t n-m If t is n >t n-1 >t n-2 …>t n-m Then go to S7 if not T n >t n-1 >t n-2 …>t n-m If yes, returning to S4;

Therefore, the cooking cavity needs to be heated in advance, namely, the heating element is closed before the probe detects that the temperature is increased to the preset temperature, so that the temperature in the cooking cavity is prevented from being increased to be higher than a high-temperature set value due to the redundant heat of the heating element; and opening the heating element before the probe detects that the temperature is reduced to the preset temperature so as to prevent the temperature in the cooking cavity from being reduced to be lower than the low-temperature set value. Therefore, the accuracy of the control of the temperature in the cooking cavity is guaranteed, the heating frequency of the heating element can be reduced, and compared with the mode that the temperature control precision of the cooking cavity is guaranteed by controlling frequent switching of the heating element of the cooking device in the prior art, the method has the advantages of saving energy, reducing consumption and prolonging the service life of the heating element.

Meanwhile, if t 7 ＜t 6 ＜t 5 ＜t 4 ＞t 3 ＞t 2 ＞t 1 Then T is 4 At the inflection point of high temperature, if t 7 ＞t 6 ＞t 5 ＞t 4 ＜t 3 ＜t 2 ＜t 1 Then T is 4 Is the inflection point of low temperature. When the temperature in the cooking cavity has a high-temperature inflection point and is in a continuous cooling state, the temperature detected by the probe is less than or equal to a preset temperature T + T 1 When the heating element is turned on; when the temperature in the cooking cavity has a low-temperature inflection point and is in a continuous temperature rise state, the temperature detected by the probe is more than or equal to the preset temperature T-T 1 When the heater is turned off, the heater is turned off.
