Detailed Description
In the description of the present invention, it can be understood that the electrical device includes a cavity, and the cavity can be used for bearing heated objects required for cooking, such as food, water and the like, specifically, the electrical device can be a heating product shown in fig. 1, and the cavity can be a pot shown in fig. 1.
It can be understood that the temperature of the temperature sensing part of the electrical equipment is indicative of the bottom temperature of the cavity, and the heating part of the electrical equipment can be used for heating the cavity. Because thermal delay between temperature sensing part and the heating element, can make the heating element can accumulate the heat in heating process, if adopt high-power heating always and can have a large amount of thermal accumulations, when making electrical equipment stop heating, the temperature of temperature sensing part still can up to certain temperature, if the first threshold value that unreasonable control temperature sensing part reached when high-power heating, can lead to the temperature of temperature sensing part to rush, make by the heating member, if food or water culinary art exceed required target temperature, thereby lead to by the culinary art effect of heating member not good. If the heating is always carried out with low power, the whole heating time is too long, the waiting time of a user is too long, the satisfaction degree of the user is not high, and meanwhile, the cooking effect of the heated body is not good.
Based on the problem of the known control method of the electrical equipment, the control method, the control device and the storage medium of the electrical equipment provided by the embodiment of the invention can utilize high-power heating to enable the bottom temperature of the cavity to be close to the required target temperature, so that the time of the whole heating process is reduced; the heating of the cavity can be stopped after the corresponding parameter value of the cavity reaches a certain threshold value, so that the temperature of the cavity can be slowly conducted to a heated body in the cavity, the temperature of the heated body is prevented from exceeding the required cooking temperature, and the cooking effect of the heated body cannot be influenced; meanwhile, the parameter value of the cavity can accurately reach the required target threshold value by utilizing low-power heating. The implementation, functional features and advantages of the present invention will be further explained with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
As shown in fig. 2, an embodiment of the present invention provides a method for controlling an electrical device, where the method includes the following steps.
specifically, the electrical equipment enters a working mode, and the electrical equipment heats the cavity of the electrical equipment by using a first heating strategy.
It should be noted that the electrical equipment enters the working mode based on the operation of the user, and then heats the heated body in the cavity of the electrical equipment, such as food and water, specifically, the cavity is heated by using the heating component of the electrical equipment, at this time, the adopted first heating strategy is a high-power heating strategy, and in practical application, the first heating strategy can be a big fire heating strategy. Therefore, the temperature of the cavity can be quickly increased due to the adoption of a high-power heating strategy.
103, detecting to obtain a first parameter value of the cavity;
here, the first parameter value includes: a value corresponding to a bottom temperature of the cavity and/or a pressure within the cavity; in particular, for a sealed cavity, the first parameter value may be: a temperature parameter value and/or a pressure parameter value; the temperature values may be: a temperature value of the cavity (e.g., a bottom temperature value of the cavity or a cavity wall temperature value of the cavity); the pressure parameter value may be a pressure value and/or a pressure value within the cavity; for a non-sealed cavity, the first parameter value comprises: the bottom temperature of the cavity corresponds to a value.
Specifically, the electrical equipment detects the bottom temperature of the cavity and/or the pressure in the cavity, and obtains a first parameter value corresponding to the bottom temperature of the cavity and/or the pressure in the cavity.
It should be noted that, when the electrical apparatus is heated by using the first heating strategy, the temperature of the cavity inevitably rises, the bottom temperature of the cavity and/or the pressure in the cavity also inevitably rises, and at this time, the electrical apparatus detects the bottom temperature of the cavity and/or the pressure in the cavity in real time or according to a preset time interval, and obtains a first parameter value corresponding to the bottom temperature of the cavity and/or the pressure in the cavity.
specifically, when the electrical equipment detects that a first parameter value corresponding to the cavity is greater than or equal to the first threshold value, the electrical equipment stops heating the cavity; the first threshold is a set temperature value and/or a set pressure value, and the first threshold may be a preset value, or a set value dynamically adjusted according to a heated body to be cooked, such as food or water.
Here, the first parameter value reaches the first threshold, in practical applications, the first parameter value of the cavity detected in real time or at preset time intervals is compared with a set first threshold for the electrical equipment, and when the first parameter value is greater than or equal to the set first threshold, the first parameter value is considered to reach the first threshold.
It should be noted that the size of the first threshold is related to the degree of matching between the heating element of the electrical equipment and the cavity, the thickness of the cavity wall of the cavity, the total amount of the heated body in the cavity, and the like. For example, the thicker the thickness of the cavity wall, the higher the first threshold setting, the thinner the thickness of the cavity wall, the lower the first threshold setting; the lower the degree of cooperation of the heating component with the cavity, the higher the first threshold device, the higher the degree of cooperation of the heating component with the cavity, and the lower the first threshold device; the more the total amount of the heated body in the cavity, the higher the first threshold value is set, the less the total amount of the heated body in the cavity is set, and the lower the first threshold value is set.
here, the second parameter value includes: a value corresponding to a bottom temperature of the cavity and/or a pressure within the cavity; specifically, for a sealed cavity, the second parameter value may be: a temperature parameter value and/or a pressure parameter value; the temperature values may be: a temperature value of the cavity (e.g., a bottom temperature value of the cavity or a cavity wall temperature value of the cavity); the pressure parameter value may be a pressure value and/or a pressure value within the cavity; for a non-sealed cavity, the second parameter values include: the bottom temperature of the cavity corresponds to a value.
Specifically, at a first moment after the electrical equipment stops heating the cavity, the bottom temperature of the cavity and/or the pressure in the cavity are detected, and a second parameter value corresponding to the bottom temperature of the cavity and/or the pressure in the cavity is obtained.
It should be noted that, because the heat between the heating element and the temperature sensing element of the electrical equipment is delayed, the bottom temperature of the cavity is still raised to a certain temperature value after the cavity is stopped being heated. When the temperature of the bottom of the cavity rises to a certain temperature value, the heat accumulated by the heating part is conducted to the cavity; at this time, the temperature of the heated body in the cavity, such as food or water, is not consistent with the temperature of the bottom of the cavity, so that the cavity can slowly transfer heat to the heated body, and the temperature of the bottom of the cavity begins to drop. Therefore, after the cavity stops being heated, the bottom temperature of the cavity can be in a rising stage for a period of time and then in a falling stage for a period of time until the temperature of the heated body in the cavity and the bottom temperature of the cavity gradually reach equilibrium. In this way, the heat accumulation of the heating member can be reduced by stopping heating for a while after the heating of the chamber is stopped; meanwhile, the cavity can slowly transfer heat to the heated body, and the heat difference between the bottom temperature of the cavity and the heated body can be balanced, so that the bottom temperature of the cavity and the temperature of the heated body tend to be equal.
Here, the heating power indicates the power required to be consumed per unit time during heating, and the heating speed is faster as the heating power is larger.
Specifically, the electrical equipment compares a detected second parameter value corresponding to the cavity with the second threshold, and when the second parameter value is smaller than the second threshold, the electrical equipment heats the cavity by using a second heating strategy, wherein the heating power of the second heating strategy is lower than that of the first heating strategy; at this time, the adopted second heating strategy is a low-power heating strategy, and in practical application, the second heating strategy can be a low-fire heating strategy; the second threshold value is a set temperature value and/or a set pressure value, and the second threshold value may be a preset value, or a value dynamically adjusted and set according to a heated body to be cooked at this time, such as food or water.
Here, the second threshold is a target threshold that the cavity needs to reach.
It should be noted that, when the electrical equipment detects that the second parameter value is smaller than the second threshold value, the bottom temperature of the cavity and the temperature of the heated body of the cavity, such as food or water, tend to be equal. At this time, the cavity needs to be heated by a relatively low-power heating strategy, so that the bottom temperature of the cavity can accurately reach the required target temperature.
Example two
Based on the first embodiment, as shown in fig. 3, the method further includes:
Here, the third parameter value includes: a value corresponding to a bottom temperature of the cavity and/or a pressure within the cavity; in particular, for a sealed cavity, the third parameter value may be: a temperature parameter value and/or a pressure parameter value; the temperature values may be: a temperature value of the cavity (e.g., a bottom temperature value of the cavity or a cavity wall temperature value of the cavity); the pressure parameter value may be a pressure value and/or a pressure value within the cavity; for a non-sealed cavity, the third parameter values include: the bottom temperature of the cavity corresponds to a value.
Specifically, at a second time, the electrical equipment detects the bottom temperature of the cavity and/or the pressure in the cavity, and obtains a third parameter value corresponding to the bottom temperature of the cavity and/or the pressure in the cavity, wherein the second time is earlier than the first time; the electrical equipment compares the detected third parameter value corresponding to the cavity with the set third threshold value, and when the third parameter value is greater than or equal to the third threshold value, the cavity is maintained in a heating stop state; the third threshold value is a set temperature value and/or a set pressure value, and the third threshold value may be a preset value, or a set value dynamically adjusted according to a heated body to be cooked, such as food or water; the third threshold is greater than the first threshold.
It should be noted that, here, the third parameter value of the cavity is detected at the second moment, the third parameter value is compared with the set third threshold value, and whether the heating stop state of the cavity is maintained is determined through the comparison, so that it is possible to avoid that the temperature of the heating part, which is caused by accumulating more heat, at the bottom of the cavity is excessively high, thereby greatly reducing the thermal inertia at the above step 101, and avoiding the consequence that the heated body in the cavity exceeds the required temperature and the cooking effect is poor when the cavity is heated at high power.
EXAMPLE III
Based on the second embodiment, as shown in fig. 4, the method further includes:
106b, detecting and obtaining a fourth parameter value of the cavity at a third moment after a first time interval from the second moment; continuing to heat the cavity using the first heating strategy when the fourth parameter value is less than a fourth threshold value.
Here, the fourth parameter value includes: a value corresponding to a bottom temperature of the cavity and/or a pressure within the cavity; specifically, for a sealed cavity, the fourth parameter value may be: a temperature parameter value and/or a pressure parameter value; the temperature values may be: a temperature value of the cavity (e.g., a bottom temperature value of the cavity or a cavity wall temperature value of the cavity); the pressure parameter value may be a pressure value and/or a pressure value within the cavity; for a non-sealed cavity, the fourth parameter values include: the bottom temperature of the cavity corresponds to a value.
Specifically, the electrical equipment starts timing from the second moment, detects the bottom temperature of the cavity and/or the pressure in the cavity at a third moment after the interval of the first time period, and obtains a fourth parameter value corresponding to the bottom temperature of the cavity and/or the pressure in the cavity; the electrical equipment compares a detected fourth parameter value corresponding to the cavity with a set fourth threshold value, and when the fourth parameter value is smaller than the fourth threshold value, the electrical equipment continues to heat the cavity by using a first heating strategy; the first heating strategy is a high-power heating strategy, and in practical application, the first heating strategy can be a high-fire heating strategy.
The first time length is set according to the characteristics that after the electrical equipment heats the cavity by using a first heating strategy and reaches a first threshold value, the heating is stopped, and the temperature of the bottom of the cavity rises and falls; the characteristic that the temperature of the bottom of the cavity rises is that the temperature of the bottom of the cavity can rise to a certain temperature after the cavity is stopped being heated; the characteristic of the bottom temperature loop of the cavity is that after the cavity is stopped being heated, the bottom temperature of the cavity starts to fall and falls to a certain temperature after rising to the certain temperature; the fourth threshold is set according to the bottom temperature of the cavity and the actual temperature of the heated body in the cavity.
Here, by starting to detect the fourth parameter value of the cavity only at the third time spaced from the second time by the first time, the bottom temperature of the cavity has time to conduct heat to the heated body in the cavity, thereby facilitating the bottom temperature of the cavity and the temperature of the heated body in the cavity to be equal.
It should be noted that, here, by detecting a fourth parameter value corresponding to the cavity at a third time of the first duration of the second time interval after the heating of the cavity is stopped, and comparing the fourth parameter with a fourth threshold, the bottom temperature of the cavity may be cooled to a certain temperature value due to the heating stop, and the cavity temperature may be heated again by using a high-power first heating strategy, so that the temperature value of the bottom temperature of the cavity is always maintained to reach the first threshold.
Example four
Based on the first embodiment, as shown in fig. 5, the method further includes:
Specifically, at a second moment, the electrical equipment detects the bottom temperature of the cavity and/or the pressure in the cavity, and obtains a third parameter value corresponding to the bottom temperature of the cavity and/or the pressure in the cavity, wherein the second moment is earlier than the first moment; the electrical equipment compares the detected third parameter value corresponding to the cavity with the set third threshold value; when the third parameter value is smaller than the third threshold value, the electrical equipment compares the third parameter value with the fifth threshold value; when the third parameter value is smaller than the fifth threshold value, the electrical equipment heats the cavity by using the first heating strategy; the fifth threshold is a set temperature value and/or a set pressure value, and the fifth threshold may be a preset value, or a set value dynamically adjusted according to a heated body to be cooked, such as food or water; the third threshold is greater than the first threshold, and the fifth threshold is less than or equal to the first threshold; here, the first heating strategy is a strategy that adopts the high-power heating, and in practical application, the first heating strategy may be a big fire heating strategy.
It should be noted that, here, by detecting the third parameter value of the cavity at the second time, comparing the third parameter value with the third threshold, and comparing the third parameter value with the third threshold when the third parameter value is smaller than the third threshold, it can be solved that the bottom temperature of the cavity does not overshoot to a certain temperature value after the bottom temperature of the cavity stops heating, but starts to drop to a certain temperature value, and the bottom temperature of the cavity reaches the first threshold that needs to be set again by using a high-power heating strategy.
EXAMPLE five
As shown in fig. 6, an embodiment of the present invention provides a method for controlling an electrical device, where the method includes the following steps.
specifically, the electrical equipment enters a working mode, and the electrical equipment heats the cavity of the electrical equipment by using a first heating strategy.
It should be noted that the electrical equipment enters the working mode based on the operation of the user, and then heats the heated body in the cavity of the electrical equipment, such as food and water, specifically, the cavity is heated by using the heating component of the electrical equipment, at this time, the adopted first heating strategy is a high-power heating strategy, and in practical application, the first heating strategy can be a big fire heating strategy. Therefore, the temperature of the cavity can be quickly increased due to the adoption of a high-power heating strategy.
here, the first parameter value includes: a value corresponding to a bottom temperature of the cavity and/or a pressure within the cavity; specifically, for a sealed cavity, the first parameter value includes: a value corresponding to a bottom temperature of the cavity and/or a pressure within the cavity; for a non-sealed cavity, the first parameter value comprises: the bottom temperature of the cavity corresponds to a value.
Specifically, the electrical equipment detects the bottom temperature of the cavity and/or the pressure in the cavity, and obtains a first parameter value corresponding to the bottom temperature of the cavity and/or the pressure in the cavity.
It should be noted that, when the electrical apparatus is heated by using the first heating strategy, the temperature of the cavity inevitably rises, the bottom temperature of the cavity and/or the pressure in the cavity also inevitably rises, and at this time, the electrical apparatus detects the bottom temperature of the cavity and/or the pressure in the cavity in real time or according to a preset time interval, and obtains a first parameter value corresponding to the bottom temperature of the cavity and/or the pressure in the cavity.
specifically, when the electrical equipment detects that a first parameter value corresponding to the cavity is greater than or equal to the first threshold value, the electrical equipment stops heating the cavity; the first threshold is a set temperature value and/or a set pressure value, and the first threshold may be a preset value, or a set value dynamically adjusted according to a heated body to be cooked, such as food or water.
Here, the first parameter value reaches the first threshold, in practical applications, the first parameter value of the cavity detected in real time or at preset time intervals is compared with a set first threshold for the electrical equipment, and when the first parameter value is greater than or equal to the set first threshold, the first parameter value is considered to reach the first threshold.
It should be noted that the size of the first threshold is related to the degree of matching between the heating element of the electrical equipment and the cavity, the thickness of the cavity wall of the cavity, the total amount of the heated body in the cavity, and the like. For example, the thicker the thickness of the cavity wall, the higher the first threshold setting, the thinner the thickness of the cavity wall, the lower the first threshold setting; the lower the degree of cooperation of the heating component with the cavity, the higher the first threshold device, the lower the degree of cooperation of the heating component with the cavity, and the lower the first threshold device; the more the total amount of the heated body in the cavity, the higher the first threshold value is set, the less the total amount of the heated body in the cavity is set, and the lower the first threshold value is set.
Here, the third parameter value includes: a value corresponding to a bottom temperature of the cavity and/or a pressure within the cavity; in particular, for a sealed cavity, the third parameter values include: a value corresponding to a bottom temperature of the cavity and/or a pressure within the cavity; for a non-sealed cavity, the third parameter values include: the bottom temperature of the cavity corresponds to a value.
Specifically, at a second moment, the electrical equipment detects the bottom temperature of the cavity and/or the inside of the cavity, and obtains a corresponding third parameter value of the bottom temperature of the cavity and/or the inside of the cavity, wherein the second moment is earlier than the first moment; the electrical equipment compares the detected third parameter value corresponding to the cavity with the set third threshold value, and when the third parameter value is greater than or equal to the third threshold value, the cavity is maintained in a heating stop state; the third threshold is a set temperature value and/or a set temperature value, and the third threshold may be a preset value, or a set value dynamically adjusted according to a heated body to be cooked, such as food or water; the third threshold is greater than the first threshold.
It should be noted that, here, the third parameter value of the cavity is detected at the second moment, the third parameter value is compared with the set third threshold value, and whether the heating stop state of the cavity is maintained is determined through the comparison, so that it is possible to avoid that the temperature of the heating part, which is caused by accumulating more heat, at the bottom of the cavity is excessively high, thereby greatly reducing the thermal inertia at the above step 101, and avoiding the consequence that the heated body in the cavity exceeds the required temperature and the cooking effect is poor when the cavity is heated at high power.
Here, the second parameter value includes: a value corresponding to a bottom temperature of the cavity and/or a pressure within the cavity; specifically, for a sealed cavity, the second parameter values include: a value corresponding to a bottom temperature of the cavity and/or a pressure within the cavity; for a non-sealed cavity, the second parameter values include: the bottom temperature of the cavity corresponds to a value.
Here, the fourth parameter value includes: a value corresponding to a bottom temperature of the cavity and/or a pressure within the cavity; in particular, for a sealed cavity, the fourth parameter values include: a value corresponding to a bottom temperature of the cavity and/or a pressure within the cavity; for a non-sealed cavity, the fourth parameter values include: the bottom temperature of the cavity corresponds to a value.
Specifically, the electrical equipment starts timing from the second moment, detects the bottom temperature of the cavity and/or the pressure in the cavity at a third moment after the interval of the first time period, and obtains a fourth parameter value corresponding to the bottom temperature of the cavity and/or the pressure in the cavity; and the electrical equipment compares the detected fourth parameter value corresponding to the cavity with a set fourth threshold value, starts timing from the third moment when the fourth parameter value is greater than or equal to the fourth threshold value, detects the bottom temperature of the cavity and/or the pressure in the cavity in real time or at preset time intervals at the fourth moment separated by the second time length, and obtains a second parameter value corresponding to the bottom temperature of the cavity and/or the pressure in the cavity.
Here, the heating power indicates the power required to be consumed per unit time during heating, and the heating speed is faster as the heating power is larger.
Specifically, the electrical equipment compares a detected second parameter value corresponding to the cavity with the second threshold, and when the second parameter value is smaller than the second threshold, the electrical equipment heats the cavity by using a second heating strategy, wherein the heating power of the second heating strategy is lower than that of the first heating strategy; at this time, the adopted second heating strategy is a low-power heating strategy, and in practical application, the second heating strategy can be a low-fire heating strategy; the second threshold value is a set temperature value and/or a set pressure value, and the first threshold value may be a preset value, or a set value dynamically adjusted according to a heated body to be cooked at this time, such as food or water.
Here, the second threshold is a target threshold that the cavity needs to reach.
Here, when the second parameter value is smaller than the second threshold value, the cavity is heated by using a second heating strategy, and the second parameter value is compared with the second threshold value at a fourth time of the second duration, so that after the bottom temperature of the cavity slowly transfers heat to the heated body of the cavity, if the bottom temperature of the cavity after cooling still exceeds the target temperature required by the bottom temperature of the cavity, the operation of heating the cavity is still performed, so that the bottom temperature of the cavity is further balanced with the temperature of the heated body in the cavity, and the cavity is facilitated to accurately reach the required target threshold value.
It should be noted that, when the electrical equipment detects that the second parameter value is smaller than the second threshold value, the bottom temperature of the cavity and the temperature of the heated body of the cavity, such as food or water, tend to be equal. At this time, the cavity needs to be heated by a low-power heating strategy, so that the temperature of the cavity can accurately reach the required target temperature.

and/or, if the fifth parameter value is greater than or equal to the second threshold value, suspending heating by using the second heating strategy, and continuing to heat the cavity by using the second heating strategy when the redetected fifth parameter value is less than the second threshold value.

It should be noted that, here, by comparing, within a certain time, a fifth parameter value corresponding to the cavity detected by the electrical equipment with the second threshold value, heating the cavity with a second heating strategy when the fifth parameter value is less than the second threshold value, when the fifth parameter value is greater than or equal to the second threshold value, suspending heating of the cavity, therefore, in the third time period, on one hand, the heat of the cavity is slowly conducted to the heated body in the cavity, so that the heat difference between the bottom temperature of the cavity and the heated body is further balanced, on the other hand, the heating component can not accumulate too much heat to be conducted to the cavity due to the low-power heating, the cavity is always maintained near the required target threshold value, and the cavity can accurately reach the required target threshold value.
