One or more technical solutions provided in the embodiments of the present application at least have the following technical effects or advantages:

1. the real-time heating power of the induction cooker is determined according to the weight and temperature change of the container, so that the temperature control problem in the current hot pot mode is effectively solved. In the hot pot mode, when the food and water in the container are increased, the increase degree of the current weight relative to the first weight and the lower degree of the current temperature relative to the preset hot pot temperature can be judged according to the current weight and the temperature monitored in real time. According to the relative magnitude, the real-time heating power of the induction cooker is automatically adjusted to be high enough to quickly heat the container to a preset temperature. Therefore, the user can reach the preset temperature without waiting for too long time when food and water become more, and the user experience is improved.

3.

Detailed Description

The terminology used in the following embodiments of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in the specification of the present application and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms as well, unless the context clearly indicates to the contrary. It should also be understood that the term "and/or" as used in this disclosure is intended to encompass any or all possible combinations of one or more of the listed items.

The terms "first," "second," and the like, are used below for descriptive purposes only and are not to be construed as implying or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature, and in the description of embodiments of the application, unless otherwise indicated, the meaning of "a plurality" is two or more.

Conventional induction cooker devices generally rely only on a preset heating power for heating, and cannot be dynamically adjusted according to the amount of food and water in the container. In this case, if the amount of food or water in the container is small, the preset heating power may be excessively high, resulting in overheating, wasting energy, and possibly negatively affecting the food or water. Conversely, if the amount of food or water in the container is large, the preset heating power may be too low, resulting in an extended heating time, affecting the dining experience of the user.

The embodiment of the application provides a control method of heating power of an induction cooker, which is used for intelligently controlling the heating power in a hot pot mode, improving the heating speed and reducing energy waste. The following describes a control method of heating power of an induction cooker in an embodiment of the application:

fig. 1 is a schematic flow chart of a method for controlling heating power of an induction cooker according to an embodiment of the application.

S101, after an induction cooker is started for a preset preheating time period, determining a first weight of a container on a heating area of the induction cooker;

in response to the operation of starting the induction cooker by the user, the power control device controls the induction cooker to start preheating first, and the preset preheating time period and the preheating power can be preset by the user or can be preset by the factory, and the preset preheating time period is not limited herein, for example, the preset preheating time period is set to be 10 minutes. After the preset preheating time period is reached, the power control device determines the first weight of the container on the heating area of the electromagnetic oven.

In some embodiments, the power control device may be part of a component of an induction cooker; in some embodiments, the power control device may be an external terminal or a server, and is connected to the induction cooker in a wired or wireless manner, so as to control the induction cooker, which is not limited herein.

It will be appreciated that the user has normally completed the addition of both the container and the initially desired food, water, etc. items in the container prior to the start of the induction cooker, or during a preset pre-heating period.

The first weight is the total weight of the container placed on the heating area of the electromagnetic oven and the internal content (food, water and the like) of the container after the preset preheating time period is over.

In some embodiments, the power control device may monitor the weight in real time through a weight sensor provided in the heating area of the induction cooker, and record the weight at this moment as the first weight at the end of the preset warm-up period.

Assuming that a user places a container filled with food materials on an induction cooker, the preset preheating time period set by the user is 10 minutes, and after the induction cooker is started, the induction cooker is started to be preheated. After 10 minutes, the induction cooker automatically records the total weight of the container and the food material at the moment, for example, the total weight is recorded as 2kg, and the recorded 2kg is the first weight at the moment.

S102, if the induction cooker is in a hot pot mode, monitoring the current weight and the current temperature of a container on the heating area in real time after the preset preheating time period;

when the induction cooker is in the hot pot mode, the power control device starts a real-time monitoring program after the preset preheating stage is finished. The program continuously monitors two parameters: real time weight and real time temperature of the container. The weight is monitored to detect the increase or decrease of food or water in the container; the temperature is monitored in order to know the real time temperature to which the food material is heated. By acquiring the change data of the two parameters, the power control device can perform corresponding intelligent control.

Wherein the current weight is the total weight of the container and the content obtained by real-time monitoring; the current temperature is the temperature of the container obtained by real-time monitoring and is used for representing the temperature of food in the container.

In some embodiments, the power control device may also monitor the current weight and current temperature of the container over the heating zone, if not in the hot pot mode, as not limited herein. In the hot pot mode, a user can normally cover and uncover the pot cover frequently, so that the influence of the weight of the pot cover on temperature control can be avoided.

For example, after a preset preheating time period of 10 minutes, a weight sensor and a temperature sensor built in the induction cooker continuously monitor the weight and the temperature of the hot pot, and feed data back to a power control device, for example, the weight is monitored to be increased from 2kg to 2.5kg, and the temperature is monitored to be increased from 20 ℃ to 30 ℃. At this time, 2.5kg is the current weight, and 30℃is the current temperature.

S103, determining real-time heating power of the induction cooker based on the relative sizes of the first weight and the current weight and the relative heights of the preset hot pot temperature and the current temperature; wherein the larger the current weight is relative to the first weight, the lower the current temperature is relative to the preset hot pot temperature, the higher the real-time heating power is;

the power control device will be based on two sets of data monitored: the real-time heating power is determined according to the magnitude relation between the current weight and the first weight and the magnitude relation between the current temperature and the preset temperature. The principle is as follows: the larger the current weight is relative to the first weight, the lower the current temperature is relative to the preset hot pot temperature, which means that a user needs to quickly heat a lot of food materials and water, and the higher the real-time heating power is; conversely, the smaller the current weight relative to the first weight, the closer or higher the current temperature relative to the preset hotpot temperature, indicating that the user has approached the end of a meal or is eating slowly, the lower the real-time heating power.

In some embodiments, a predetermined power lookup table may be used to determine the real-time heating power, and in some embodiments, a predetermined algorithm may be used to determine the real-time heating power, as not limited herein.

Illustratively, the following is a preferred preset algorithm formula, which may enable smoother and more accurate calculation of the real-time heating power variation:

wherein P is real-time heating power, M1 is the current weight, M0 is the first weight, and the weight unit is kg; t0 is the preset hot pot temperature, and T1 is the current temperature; k1 is a preset weight sensitivity coefficient, and the value range is 1 to 500; k2 is a preset temperature sensitivity coefficient, and the value range is 1 to 500. The weight unit is kg; PY is a preset basic heating power.

Taking an electromagnetic oven with a common highest power of 2000W as an example, if PY is set to 500W, K1 is set to 300, and K2 is set to 500. If the first weight is 2kg, the temperature of the preset hot pot is 90 degrees. If the current weight is 5kg and the current temperature is 30 ℃, using the formula to calculate P to be 1786W; if the current weight is 2.2kg, the current temperature is 65 degrees, and P is 1064W by using the formula.

The formula considers two variables of temperature and weight at the same time, and can reflect the cooking state more comprehensively. The split index operator is introduced, so that the correlation between temperature and weight is established, and the heat conduction rule in cooking is well simulated. Compared with simple linear weighting, the nonlinear calculation mode can make the control more sensitive and accurate, and can remarkably improve the intelligent temperature control performance of the induction cooker.

S104, after the current temperature reaches the preset hot pot temperature, if the current weight is kept unchanged within a preset safety period, adjusting the heating power of the induction cooker to 0.

When the power control device monitors that the current temperature reaches the current preset hot pot temperature, if the weight of the container is continuously monitored to be unchanged within a preset safety period, the induction cooker can automatically adjust the heating power to 0, namely, the heating is stopped.

For example, assuming that the preset hot pot temperature is 70 ℃, after the current temperature is monitored to reach 70 ℃, if the weight is maintained to be 1kg for a preset 20-minute safety period, which means that the meal may have ended, the heating power is adjusted to 0 to stop heating.

In the embodiment of the application, the real-time heating power of the induction cooker is determined according to the weight and temperature change of the container, so that the temperature control problem in the current hot pot mode is effectively solved. In the hot pot mode, when the food and water in the container are increased, the increase degree of the current weight relative to the first weight and the lower degree of the current temperature relative to the preset hot pot temperature can be judged according to the current weight and the temperature monitored in real time. According to the relative magnitude, the real-time heating power of the induction cooker is automatically adjusted to be high enough to quickly heat the container to a preset temperature. Therefore, the user can reach the preset temperature without waiting for too long time when food and water become more, and the user experience is improved. Meanwhile, as the heating power can be intelligently adjusted, when the food and water are reduced, the heating power can be timely reduced, the continuous temperature increase is avoided, and the energy waste is reduced. In this way, the technical effects of rapid heating and energy saving are effectively achieved.

In practical applications, in the later stage of eating, too high a temperature can cause the food to be cooked too fast or even change in taste due to slow food consumption, and the requirements of users cannot be met. The control method of the heating power of the induction cooker can also solve the problem that the temperature is not matched with the requirement of a user by intelligently adjusting the temperature of the preset hot pot, thereby further improving the user experience and simultaneously saving the energy consumption.

Referring to fig. 2, another flow chart of a method for controlling heating power of an induction cooker according to an embodiment of the application is shown:

s201, after the induction cooker is started for a preset preheating time period, determining a first weight of a container on a heating area of the induction cooker;

s202, if the induction cooker is in a hot pot mode, monitoring the current weight and the current temperature of a container on the heating area in real time after the preset preheating time period;

steps S201 to S202 are similar to steps S101 to S102 in the embodiment shown in fig. 1, and reference may be made to the description of the relevant steps, which will not be repeated here.

S203, determining a preset chafing dish temperature based on the first weight, the monitored maximum weight value of the container on the heating area and the current weight;

the power control device determines the preset chafing dish temperature according to the first weight, the recorded maximum weight and the current weight. The principle is that the more the food material quantity is, the higher the temperature of the hot pot is required to be set, otherwise, the lower the temperature of the hot pot is required to be set.

In particular, the power control means may determine a monitored maximum value of the weight of the container over the heating zone; if the current weight is the maximum weight value, determining that the preset chafing dish temperature is a first temperature value; if the current weight is not less than the first weight and less than the maximum weight, determining that the preset chafing dish temperature is a second temperature; the second temperature is less than the first temperature; if the current weight is smaller than the first weight, determining that the preset hot pot temperature is a third temperature; the third temperature is smaller than the second temperature and is larger than the preset lowest temperature of the hot pot.

For example, assuming that the first weight is 2kg, the preset lowest temperature of the hot pot is 60 degrees, the first temperature value is 90 degrees, the second temperature value is 80 degrees, and the third temperature value is 70 degrees. If the monitored current weight is 1.5kg, the power control device updates the current preset hot pot temperature to be 70 ℃ of a third temperature value; if the monitored current weight is 2.5kg, the power control device updates the current preset hot pot temperature to be 80 ℃ of a third temperature value; if the monitored current weight is 5kg and is the maximum weight recorded so far, the power control device updates the current preset hot pot temperature to be 90 degrees at the first temperature value.

S204, recording the time interval of each weight increase;

the power control means may record the time interval between two weight increases each time an increase in the weight of the container is monitored.

For example, the first weight increase detection time is 10:05, increasing from 2kg to 2.1kg; the second weight increase detection time was 10:25, increasing from 2.1kg to 2.2kg. The time interval between these two weight increases is 10:25-10:05=20 minutes.

S205, under the condition that the longest time interval is larger than the preset safety duration, taking the sum of the preset safety duration and the longest time interval as the updated preset safety duration;

if the maximum value of the recorded weight increase time interval is greater than the preset safety duration, the feeding speed of the user is far lower than the expected speed, and the power control device can add the preset safety duration and the maximum time interval to serve as a new updated preset safety duration.

For example, the original preset safety duration is 10 minutes, if the maximum time interval for the recorded weight increase is 15 minutes. The power control device may update the preset safe duration to 10 minutes +15 minutes = 25 minutes. Thus, the safety is ensured, and the requirements of users meeting various eating speeds are also ensured.

S206, determining real-time heating power of the induction cooker based on the relative sizes of the first weight and the current weight and the relative heights of the preset hot pot temperature and the current temperature; wherein the larger the current weight is relative to the first weight, the lower the current temperature is relative to the preset hot pot temperature, the higher the real-time heating power is;

s207, after the current temperature reaches the preset hot pot temperature, if the current weight is kept unchanged within a preset safety period, adjusting the heating power of the induction cooker to 0;

steps S206 to S207 are similar to steps S103 to S104 in the embodiment shown in fig. 1, and reference may be made to the description of the relevant steps, which will not be repeated here.

And S208, when the heating area is determined not to be provided with the container, prohibiting heating.

When the induction cooker monitors that no container is placed on the heating area, the power control device needs to prohibit continuous heating and set the heating power to 0 for safety.

Specifically, in some embodiments, the power control device may determine that the container is not placed on the heating area if it is determined that the current weight is less than the preset container weight; it may also be determined, without limitation, that no container is placed on the heating zone by monitoring whether the heating load falls below a preset minimum load value.

In the embodiment of the application, the contradiction between the user demand and the temperature control in the hot pot mode is effectively solved by adopting the mode of determining different stages of the preset hot pot temperature according to the change of the weight of the container. According to the current weight monitored in real time, the system judges the relation between the current weight and the first weight, and further determines different stages of the preset hot pot temperature. When the current weight is the maximum value, the temperature of the preset chafing dish is set to be a first temperature value so as to meet the requirement of more food and water in the container; when the current weight is not less than the first weight and is less than the maximum value, the preset hot pot temperature is set to be a second temperature value, and the second temperature is less than the first temperature so as to adapt to the condition that the food and water in the container are in the continuous dining process; when the current weight is smaller than the first weight, the preset hot pot temperature is set to be a third temperature value, and the third temperature is smaller than the second temperature and is larger than the preset lowest temperature of the hot pot at the same time, so that the hot pot is suitable for the conditions that the food and water in the container are less and the temperature needs to be kept. Through the mode, the temperature requirements under different dining conditions are effectively met, and the user experience is improved.
