The present application is based upon and claims the benefit of priority from Chinese Patent Application No. 201810242383.1, filed on Mar. 22, 2018, the entire content of which is incorporated herein by reference.
The disclosure relates to the technology of temperature control, and in particular to a temperature control method and a temperature control apparatus for a cookware, a cookware and a storage medium.
For most existing baking machines, the temperature sensor disposed at the center position of the baking tray, and the temperature sensor directly detects the temperature of the center of the baking tray. After preheating, a food is placed on the baking tray for cooking. When the food is just placed in a central region of the baking tray, since the food itself has a relatively low temperature, the food would absorb quickly the heat from the central region of the baking tray, thereby reducing the temperature of the central region of the baking tray. When the temperature sensor detects that the temperature of the baking tray has been reduced to the lowest temperature threshold value, a heating device is started to work, so that the working temperature of the baking tray is in a normal working range, so as to ensure the cooking effect of the food. However, when the food is placed on an edge region of the baking tray, the food would absorb the heat from the edge region of the baking tray, which has a relatively small effect on the temperature of the center region of the baking tray in a short period of time, and thus the temperature sensor in the center region of the baking tray cannot detect the temperature reduction of the baking tray in time. Accordingly, the operation of the heating device cannot be controlled in time, so that the baking tray cannot provide a reliable cooking temperature for the food.
The embodiments of the disclosure are expected to provide a temperature control method and a temperature control apparatus for a cookware, a cookware and a storage medium, to improve the flexibility of temperature control and improve the intelligent level of the cookware.

Hereinafter, the technical solutions in the embodiments of the disclosure will be described clearly and completely in combination with the accompanying drawings in the embodiments of the disclosure.
First Embodiment
In the first embodiment, a cookware includes a first heating device and a plurality of temperature sensors arranged at different positions of a first heating area. Herein, the first heating device is configured to heat the first heating area, and the cookware may be a home kitchen appliance such as a baking machine, a steak machine, an induction cooker, a rice cooker or the like.
In step 101, temperature values detected by the plurality of temperature sensors are collected.
As an example, when the heating area is a baking tray, the food is in contact with an outer surface of the baking tray, and the plurality of temperature sensors are in contact with an inner surface of the baking tray to detect the working temperature of the baking tray.
Specifically, the plurality of temperature sensors may be in a form of a radial distribution or a lattice distribution. The radial distribution includes a center position of the heating area and equally-spaced positions on a circumference of a circle that spreads outward from the center position by at least a radius. The lattice distribution includes a plurality of lattice positions with an equal row spacing and an equal column spacing.
In step 102, a minimum temperature value and a maximum temperature value of the first heating area are determined from all the collected temperature values.
Herein, temperature values of the first heating area include T1, T2 to Tm. A number of m temperature values are compared to determine the minimum temperature value Tmin and the maximum temperature value Tmax. The two values can be used as a basis for controlling the starting and stopping of the first heating device, to improve the reliability of temperature control.
In step 103, the first heating device is started if the minimum temperature value and the maximum temperature value of the first heating area satisfy a preset temperature increase condition.
As an example, the temperature increase condition includes: the minimum temperature value being less than a lowest temperature threshold value, and the maximum temperature value being less than a highest temperature threshold value. Herein, before the first heating device is started, the first heating device is in a stopped state. Therefore, it is necessary to start the first heating device to increase the temperature of the first heating area.
As an example, the first heating device may be an electrical heating tube, a heater with a Positive Temperature Coefficient (PTC) characteristic, or an electrical heating film, etc.
In step 104, the first heating device is stopped if the minimum temperature value and the maximum temperature value of the first heating area satisfy a preset temperature reduction condition.
As an example, the temperature reduction condition includes: the minimum temperature value being greater than or equal to a lowest temperature threshold value, or the maximum temperature value being greater than or equal to a highest temperature threshold value. Herein, before the first heating device is stopped, the first heating device is in a working state. Therefore, it is necessary to stop the first heating device to reduce the temperature of the first heating area.
Optionally, the lowest temperature threshold value may be determined according to the minimum temperature value which guarantees the cooking effect of the food when the cookware is working, and the highest temperature threshold value may be determined according to the maximum temperature value which is allowed when the cookware is working. For example, since there are differences in sensitivities of the sensors and in temperatures of cooking ingredients, the range of the minimum temperature value may be set between 150° C. and 210° C., preferably 180° C. In order to ensure that the baking machine works safely, a preset protection temperature of the baking tray is set between 250° C. and 300° C., and the maximum temperature value may be 250° C.
In another optional embodiment, both the lowest temperature threshold value and the highest temperature threshold value may be determined according to a working mode selected in the cookware. For example, the cookware in a working mode has a corresponding temperature range. An upper limit value of the temperature range is the highest temperature threshold value and a lower limit value of the temperature range is the lowest temperature threshold value. For example, the working modes of the baking machine include: a steak mode, a pancake mode, a fried egg mode and the like. A temperature range corresponding to the steak mode is between 185° C. and 205° C., in which the highest temperature threshold value is 205° C., and the lowest temperature threshold value is 185° C. A temperature range corresponding to the pancake mode is between 180° C. and 200° C., in which the highest temperature threshold value is 200° C., and the lowest temperature threshold value is 180° C. A temperature range corresponding to the fried egg mode is between 170° C. and 190° C., in which the highest temperature threshold value is 190° C., and the lowest temperature threshold value is 170° C.
Thus, the temperature control method in the embodiment of the disclosure may further includes the following steps: the lowest temperature threshold value and the highest temperature threshold value corresponding to each working mode of the cookware are preset; and the lowest temperature threshold value and the highest temperature threshold value of the cookware in the current working mode are determined.
In an actual implementation, the heating device is started, if Tmin is less than a preset lowest temperature threshold value TL and Tmax is less than a preset highest temperature threshold value TH; or else, the heating device is stopped, if Tmin is greater than or equal to the preset lowest temperature threshold value TL or Tmax is greater than or equal to the highest temperature threshold value TH. During the entire cooking process, cooking programs intermittently read the temperature values of all the temperature sensors, and judge whether to start or stop heating according to the above method until timing of the cooking program is over.
In the embodiments of the disclosure, step 101 to step 104 may be performed by a processor of the cookware, or performed by a processor of a temperature control apparatus for the cookware. The performing order of step 103 and step 104 as well as whether to perform step 103 and step 104 are not limited by the embodiments of the disclosure, but are determined based on the collected minimum temperature value and maximum temperature value.
In the embodiments of the disclosure, the cookware includes a first heating device and a plurality of temperature sensors arranged at different positions of a first heating area. The method includes the following steps: temperature values detected by the plurality of temperature sensors are collected; a minimum temperature value and a maximum temperature value of the first heating area are determined from all the collected temperature values; the first heating device is started if the minimum temperature value and the maximum temperature value of the first heating area satisfy a preset temperature increase condition; and the first heating device is stopped if the minimum temperature value and the maximum temperature value of the first heating area satisfy a preset temperature reduction condition.
By adopting the above technical solutions, the temperature of the heating area can be synthetically judged based on the temperature values detected by the plurality of temperature sensors. The heating device is started if the temperature increase condition is satisfied, so as to increase the temperature of the heating area to ensure the cooking effect of the food. The heating device is stopped if the temperature reduction condition is satisfied, so as to reduce the temperature of the heating area to ensure the safety of the cookware. In this way, the flexibility of temperature control is improved, and the intelligent level of the cookware is improved.
Second Embodiment
In order to better reflect the purpose of the disclosure, the disclosure is further exemplified on the basis of the first embodiment of the disclosure.
In the second embodiment, the cookware includes: a first heating device, a second heating device to an Nth heating device, and a plurality of temperature sensors arranged at different positions of an ith heating area. The ith heating area corresponds to an ith heating device, in which i is an integer of 1 to N. The ith heating device is configured to heat the ith heating area. The ith heating device to the Nth heating device may be electrical heating tubes, heaters with PTC characteristic, or electrical heating films etc., and may be the same device or different devices.
In step 301, temperature values detected by the plurality of temperature sensors are collected.
Herein, the temperature values detected by all of the temperature sensors on the cookware may be collected, or the temperature values detected by the temperature sensors in part of the heating areas may be collected.
In step 302, a minimum temperature value and a maximum temperature value of the ith heating area are determined from all the collected temperature values.
Herein, the minimum temperature values and the maximum temperature values of the first heating area to the Nth heating area may be determined successively. The minimum temperature value and the minimum temperature value of each heating area may also be determined, and the heating device corresponding to each heating area may be controlled according to the determined maximum and minimum temperature values.
In addition, the first heating area to the Nth heating area may be set flexibly according to the use of the cookware. For example, an upper baking tray of the baking machine is divided into several heating areas, or a lower baking tray of the baking machine is divided into several heating areas.
In step 303, it is judged whether the minimum temperature value and the maximum temperature value of the ith heating area satisfy the preset temperature increase condition. If it is, step 304 is performed; if it is not, step 305 is performed.
As an example, the temperature increase condition includes: the minimum temperature value of the ith heating area being less than a lowest temperature threshold value, and the maximum temperature value of the ith heating area being less than a highest temperature threshold value.
In step 304, the ith heating device is started.
After step 304 is performed, step 301 is returned, so as to continue to collect temperature values detected by the plurality of temperature sensors at the next time, thereby achieving real-time monitoring of the temperature of the first heating area to the temperature of the Nth heating area.
In step 305, it is judged whether the minimum temperature value and the maximum temperature value of the ith heating area satisfy the preset temperature reduction condition. If it is, step 306 is performed; if it is not, step 301 is returned.
As an example, the temperature reduction condition includes: the minimum temperature value of the ith heating area being greater than or equal to the lowest temperature threshold value, or the maximum temperature value of the ith heating area being greater than or equal to the highest temperature threshold value.
In step 306, the ith heating device is stopped.
After step 306 is performed, the process returns to step 301, so as to continue to collect temperature values detected by the plurality of temperature sensors at the next time, thereby achieving real-time monitoring of the temperature of the first heating area to the temperature of the Nth heating area until the cookware is stopped. Therefore, no matter which heating area the food is placed in, temperature change of the heating area may be detected in time, and heating is controlled according to the temperature change. In addition, the accuracy of temperature control in the heating areas may be improved by controlling independently starting and stopping of the plurality of heating devices.
Optionally, the lowest temperature threshold value and the highest temperature threshold value corresponding to each working mode of each heating area is preset; and the lowest temperature threshold value and the highest temperature threshold value of each heating area in the current working mode are determined.
In the embodiment of the disclosure, a plurality of temperature sensors are arranged at different positions of the first heating area to the Nth heating area, to detect temperature values at different positions. In this way, no matter which one of the heating areas the food or the cooker is placed in, temperature change of the heating area may be detected in time, and starting or stopping of the heating device may be controlled according to the temperature change, so as to ensure that the heating area may provide a uniform temperature and improve the cooking effect.
