Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Fig. 1 is a schematic structural diagram of an induction cooker and a cooker, as shown in fig. 1, wherein an induction cooker 10 located below includes an induction cooker control system 11, a microcrystal panel 12 and a microcrystal panel bottom temperature sensor 13.

Wherein, electromagnetism stove control system 11 regulates and control each item work of electromagnetism stove 10, can place the pan on micrite panel 12, and when electromagnetism stove 10 was in the culinary art state, the temperature on micrite panel 12 can rise. The microcrystalline panel bottom temperature sensor 13 may directly measure the temperature of the microcrystalline panel 12. The microcrystalline panel is a kind of induction cooker panel, and fig. 1 illustrates an example in which an induction cooker panel is used as a microcrystalline panel.

The cookware placed on the microcrystal panel 12 can be common cookware or precisely-controlled cookware. In fig. 1, a pan placed on the microcrystal panel 12 is taken as an example of a precisely controlled pan 20.

On the smart pot 20, including removable handle 21, handle lid 22, smart control box subassembly 23, pan steam temperature sensor 24, pan steam temperature sensor installation trompil 25, pan bottom temperature sensor 26 and pan bottom temperature sensor installation slot 27.

Wherein, include the pan control system in the accurate control box subassembly 23, the work of each subassembly on the accurate control pan 20 of control. The pot steam temperature sensor 24 is used for measuring the temperature of the steam inside the pot 20, and the pot steam temperature sensor 24 is inserted into the inside of the pot 20 at the pot steam temperature sensor mounting opening 25. The pot bottom temperature sensor 26 is inserted into the pot bottom temperature sensor mounting slot and is fixedly mounted, and the pot bottom temperature sensor 26 can be used for measuring the temperature of the bottom of the pan of the precisely controlled pot 20. The precise control cooker 20 further comprises a temperature measuring point 28, and the temperature measuring point 28 is a temperature measuring point which is finally embedded into the bottom of the cooker after the cooker bottom temperature sensor 26 is installed.

After the induction cooker 10 starts to work, the microcrystalline panel bottom temperature sensor 13 can acquire the temperature of the microcrystalline panel 12, the pot steam temperature sensor 24 can acquire the temperature of the steam in the precisely controlled pot 20, and the pot bottom temperature sensor 26 can acquire the temperature of the bottom of the precisely controlled pot 20. Under different cooking modes, the temperature sensors can measure the temperature simultaneously, or only one or more of the temperature sensors can measure the temperature, and finally the induction cooker control system 11 carries out uniform temperature monitoring processing.

Fig. 2 is a schematic view of a temperature control system according to an embodiment of the present application, and as shown in fig. 2, a pan placed on a panel of an induction cooker is taken as an example of a precisely controlled pan.

The pan control system of the precisely controlled pan comprises a pan controller 201, a steam temperature detection module 202, a thermocouple temperature detection module 203, an anti-overflow detection module 204 and a wireless communication module 205. Wherein, steam temperature detection module 202 mainly includes and is located the inside steam temperature sensor of accurate control pan, and steam temperature sensor can send the steam temperature data that the measurement obtained for the pan controller. The thermocouple temperature detection module 203 mainly comprises a pot bottom temperature sensor, and the pot bottom temperature sensor can send measured temperature data of the bottom of the pot to a pot controller. The overflow prevention detection module 204 mainly detects whether the inside of the cookware overflows. The wireless communication module 205 is mainly used for interaction between a cookware control system and an induction cooker control system.

The induction cooker control system comprises an induction cooker controller 206, a resonance heating module 207, an operation display module 208 and a wireless communication module 209, wherein the resonance heating module 207 is mainly used for heating when the induction cooker works, and the operation display module 208 can be used for a user to switch and check different cooking modes.

In the pot control system, the pot controller 201 can obtain the temperature data of the steam temperature sensor and the temperature data of the pot bottom temperature sensor, and then send the data to the induction cooker control system through the wireless communication module 205.

In current temperature control systems, the operating temperature sensors may be different for different cooking modes. For example, when the pot placed on the panel of the induction cooker is a common pot, the temperature of the microcrystal panel is obtained mainly through the temperature sensor at the bottom of the microcrystal panel, and the temperature at the bottom of the pot is indirectly obtained. When placing the pan on the electromagnetism stove panel for the accurate control pan, under modes such as fried dish, fry, barbecue, mainly acquire the temperature of pan bottom through pan bottom temperature sensor, under modes such as boiling congee, a kind of deep pot hot water, water out, mainly acquire the temperature of pan steam and so on through the steam temperature sensor in the pan.

In some cases, the temperature sensor may be separated from the measured object due to position movement, or a circuit failure of the temperature sensor, or the temperature sensor is not calibrated correctly, so that the difference between the temperature output by the temperature sensor and the actual temperature of the measured object is large, and at this time, the temperature sensor cannot correctly reflect the actual temperature of the measured object. For example, when the temperature sensor at the bottom of the cookware breaks down, the temperature at the bottom of the cookware is too high, but the temperature data of the temperature sensor at the bottom of the cookware is low, the temperature control of the system is abnormal, the bottom of the cookware is burned dry, and the induction cooker is damaged.

Based on this, the embodiment of the application provides a temperature control scheme, which aims at the problem of abnormal system temperature control caused by possible failure of a temperature sensor in a temperature control system. The scheme of the present application will be described below.

Fig. 3 is a schematic flow chart of a temperature control method provided in an embodiment of the present application, and as shown in fig. 3, the method may include:

s31, when the induction cooker is in a cooking state, acquiring the heating power and the heating time of the induction cooker.

When the induction cooker is in a cooking state, the induction cooker can heat a cooker placed on the induction cooker panel. When the induction cooker is in a cooking state, the heating power and the heating time of the induction cooker can be obtained, and both the heating power and the heating time are related to the heating heat quantity of the induction cooker.

When the pan is placed on the induction cooker, under the same condition, the heating power is higher, the heating time is longer, and the temperature rise is higher, wherein the temperature rise part can be a panel which is in contact with the pan on the induction cooker, can also be the pan bottom of the pan, can also be the temperature in the pan, and the like.

S32, determining the working state of at least one temperature sensor according to the heating power and the heating time, wherein the working state is a normal state or a fault state.

In the embodiment of the application, the temperature sensor is the temperature sensor inside the whole temperature control system, and the whole temperature control system comprises the induction cooker and also comprises a cooker arranged above the induction cooker. For the induction cooker, a temperature sensor can be arranged inside the induction cooker panel, so that the temperature of the induction cooker panel can be directly measured.

For the cookware, a common cookware is not provided with a temperature sensor, and part of precisely controlled cookware can be provided with a temperature sensor. For example, a temperature sensor can be arranged in the pot bottom of the precisely controlled pot to directly measure the temperature of the pot bottom. For example, a steam temperature sensor can be arranged inside the precisely controlled cooker and used for measuring the temperature of steam inside the cooker, and the like.

The working state of the temperature sensor is a normal state or a fault state, and the temperature sensor in the normal state can accurately measure the temperature of the corresponding component, so that the induction cooker can control the normal work of the induction cooker according to the temperature of the corresponding component acquired by the temperature sensor. The temperature sensor in a fault state can cause the measured temperature of the corresponding component to be inaccurate, so that accurate reference cannot be provided for the temperature control of the induction cooker.

The working state of the temperature sensor can be obtained through the heating power and the heating time of the induction cooker when the induction cooker is in the cooking state, and whether the temperature sensor is in the normal state or the fault state is judged. For example, when the heating power and the heating time of the induction cooker are obtained, the temperature of the panel of the induction cooker should generally gradually rise, and the degree of the rise has a positive correlation with the heating power and the heating time. If the temperature of the panel of the induction cooker measured by the temperature sensor positioned in the panel of the induction cooker does not rise or the rising degree is not matched with the heating power and the heating time, the temperature of the temperature sensor is inaccurate at the moment and may be in a fault state. Otherwise, the temperature sensor is in a normal state, and so on.

And S33, performing temperature monitoring processing on the induction cooker according to the working state of the at least one temperature sensor.

After the working state of at least one temperature sensor is determined, the temperature monitoring processing can be carried out on the induction cooker according to the working state of the temperature sensor. For example, when the working state of a certain temperature sensor is a normal state, the induction cooker may obtain the measurement data of the temperature sensor, obtain the temperature of the corresponding measurement component, and determine whether the temperature of the component is too high or too low according to the temperature, and when the temperature of the component is too high or too low, a corresponding prompt may be performed to prompt the user to perform the processing.

When the working state of a certain temperature sensor is a fault state, if other temperature sensors in a normal state exist, the temperature monitoring processing can be carried out on the induction cooker through the measurement data of the temperature sensors in the normal state.

If the temperature sensor in a normal state does not exist, the temperature control of the whole system is abnormal, and normal temperature control cannot be realized, the induction cooker can be controlled to shut down and stop working, so that accidents or dangers are avoided.

According to the temperature control method provided by the embodiment of the application, firstly, when the induction cooker is in a cooking state, the heating power and the heating time of the induction cooker are obtained, then the working state of at least one temperature sensor is determined according to the heating power and the heating time, and the temperature of the induction cooker is monitored and processed according to the working state of the temperature sensor. Because temperature sensor's operating condition is normal condition or fault condition, the scheme of this application embodiment, after having confirmed temperature sensor's operating condition, just can carry out corresponding temperature monitoring to the electromagnetism stove based on whether temperature sensor has the trouble, avoids because the temperature sensor goes wrong the temperature measurement system temperature control that leads to when inaccurate, thereby avoids accident and dangerous emergence.

The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

After the induction cooker is started and in a cooking state, the induction cooker can be heated, at the moment, a controller in the induction cooker can acquire heating power and heating time, and the working state of the temperature sensor is determined according to the heating power and the heating time.

Specifically, the corresponding heating amount may be obtained according to the heating power and the heating time, and then the sensing data of the temperature sensor within the preset time period is obtained, so that the working state of the corresponding temperature sensor is determined according to the heating amount and the sensing data.

The temperature sensor comprises a first temperature sensor at the bottom of a panel of the induction cooker, and when a pot placed on the panel of the induction cooker is a precisely controlled pot, the temperature sensor can also comprise a second temperature sensor arranged at the bottom of the pot and a steam temperature sensor arranged in the pot. The method of determining the operating state of the different temperature sensors based on the heating power and the heating time is similar.

For any temperature sensor, the temperature variation and/or the temperature value of the temperature sensor within a preset time period can be obtained according to the sensing data of the temperature sensor. And when the temperature variation is smaller than or equal to a first threshold value or the temperature value is not in a first range, determining that the working state of the temperature sensor is a fault state, wherein the magnitude of the first threshold value is in positive correlation with the heating heat quantity, and the first range is a range determined according to the heating heat quantity. Otherwise, determining the working state of the temperature sensor to be a normal state.

The first threshold may be a minimum limit value determined according to the heating amount, for example, it is determined that the temperature of the bottom of the pot is to be raised by 50 degrees according to the heating amount, at this time, the first threshold may be set to 50 degrees, then the temperature variation of the temperature sensor at the bottom of the pot in a preset time period is obtained, and if the variation is smaller than 50 degrees, for example, the temperature variation of the temperature sensor at the bottom of the pot in the preset time period is raised by only 30 degrees, or tends to be unchanged or even lowered, it may be determined that the temperature sensor at the bottom of the pot is in a failure state at this time.

The first threshold may also be a maximum limit value determined according to the heating amount, for example, after the heating is performed for a long time, it is determined that the temperature of the bottom of the pot needs to reach a large value (e.g., 200 degrees) according to the heating amount, at this time, the first threshold may be set to 200 degrees, then the temperature variation of the temperature sensor at the bottom of the pot within a preset time period is obtained, if the variation is smaller than 200 degrees, for example, the temperature variation of the temperature sensor at the bottom of the pot within the preset time period only rises by 120 degrees, 120 degrees are greater than the minimum limit value by 50 degrees and are not within a limit range, and the temperatures of the temperature sensor at the bottom of the microcrystal panel and the temperature sensor at the steam temperature sensor both reach or approach 200 degrees, at this time, it may be determined that the temperature sensor at the bottom of the pot is in a fault state.

The first range is a range determined according to the amount of heating heat. In a certain period of time, the larger the heating heat, the temperature of the corresponding measured object should gradually rise and tend to be stable after rising to a certain range, and the range is the first range. If the temperature value of the temperature sensor is outside the first range, it is determined that the temperature sensor is in a fault state. For example, when the temperature of a certain temperature sensor is at a limit, for example, around 30 degrees, and hardly changes as heating progresses, and the temperature data is significantly away from a reasonable range, it can be determined that the temperature sensor is in a failure state.

The determination of the operating state of the temperature sensor is described below with reference to fig. 4.

Fig. 4 is a schematic diagram of sensing data of a temperature sensor provided in an embodiment of the present application, and as shown in fig. 4, data of a sensor at the bottom of a microcrystalline panel is taken as an example. When the induction cooker is started and in a cooking mode, the induction cooker is heated for 30 seconds with certain heating power, normally, the temperature of the microcrystal panel is gradually increased, the increased temperature is at least 70 ℃, and the temperature value after heating is in a range of 20-110 ℃. In fig. 4, the variation of the sensing data of several temperature sensors at the bottom of the microcrystalline panel is illustrated.

On the left side of fig. 4, the amount of change in temperature is 90 degrees in 0 to 30 seconds, and the temperature gradually rises in 0 to 30 seconds, the graph showing that the state of the temperature sensor is a normal state.

In the middle of fig. 4, the temperature variation amount in 0-30 seconds is 30 degrees and the temperature is gradually increased in 0-30 seconds, but since the temperature variation amount is less than the minimum limit value of 70 degrees, the graph indicates that the state of the temperature sensor is a failure state.

On the right side of fig. 4, the temperature values in 0-30 seconds are always in the vicinity of 20 degrees, significantly far from a reasonable range, and the curve indicates that the state of the temperature sensor is a fault state.

Fig. 4 is merely illustrative of several possible failure scenarios and is not intended to be limiting in nature. For different temperature sensors, under the same heating power and heating time, the corresponding first preset and first ranges may be slightly different, but the determination manner is similar, and will not be described herein again.

After the working state of the at least one temperature sensor is obtained, the temperature monitoring processing can be carried out on the induction cooker according to the working state of the at least one temperature sensor.

Because the induction cooker can be in the precise control mode or the non-precise control mode under the whole temperature control system, the temperature sensors included in different working modes are different, and the corresponding temperature monitoring schemes are also different, the working mode of the induction cooker needs to be determined firstly.

Specifically, the working mode of the induction cooker can be determined according to a pot placed on the induction cooker. When the pan placed on the induction cooker is the precisely controlled pan, the working mode of the induction cooker is the precisely controlled mode; when the pan placed on the induction cooker is a common pan, the working mode of the induction cooker is a non-precise control mode. And after the working mode of the induction cooker is determined, carrying out temperature monitoring processing on the induction cooker according to the working mode of the induction cooker and the working state of at least one temperature sensor.

The temperature control schemes of the induction cooker under two different working modes are described below.

Fig. 5 is a schematic view of a process flow of monitoring the temperature of the induction cooker in the fine control mode according to the embodiment of the present application, and as shown in fig. 5, the process flow includes:

s51, acquiring the cooking mode of the induction cooker, and determining a corresponding target temperature sensor in at least one temperature sensor according to the cooking mode.

When the induction cooker is in the accurate control mode, the cooker above the induction cooker panel is indicated to be the accurate control cooker, the second temperature sensor is arranged at the bottom of the cooker, and the second temperature sensor can measure the temperature at the bottom of the cooker. The inside steam temperature sensor that still is provided with of pan, steam temperature sensor can measure the interior steam temperature of pan. Meanwhile, the bottom of the panel of the induction cooker is also provided with a first temperature sensor, and the first temperature sensor can directly measure the temperature of the panel of the induction cooker.

The cooking modes of the induction cooker include various cooking modes such as cooking, frying, roasting, fermenting and the like, for example, cooking porridge, cooking soup, boiling water, steaming and the like. The selection of the corresponding temperature sensor for controlling the temperature is different for different cooking modes.

For example, when the cooking mode is stir-frying, barbecue, etc., the temperature of pan bottom is great to the effect influence of culinary art, can regard as the corresponding target temperature sensor with the second temperature sensor this moment, and the electromagnetism stove acquires the sensing data of second temperature sensor to control the temperature according to the sensing data of second temperature sensor. For example, when the cooking mode is porridge cooking, soup cooking, water boiling and the like, the temperature of steam in the cooker has a large influence on the cooking effect, the steam temperature sensor can be used as a corresponding target temperature sensor, the induction cooker acquires sensing data of the steam temperature sensor, and the temperature is controlled according to the sensing data of the steam temperature sensor. The first temperature sensor directly measures the temperature of the panel of the induction cooker and can also indirectly measure the temperature of the bottom of the cookware, so that in some cases, the first temperature sensor can also be selected as a corresponding target temperature sensor in certain cooking modes.

And S52, if the working state of the target temperature sensor is a normal state, performing temperature monitoring processing on the induction cooker according to the sensing data of the target temperature sensor.

In the above embodiment, the method of determining the operating state of each temperature sensor according to the heating power and the heating time of the induction cooker when the induction cooker is in the cooking state is described. Because the target temperature sensor selected according to the cooking mode is a temperature sensor which is more suitable for monitoring the temperature of the induction cooker, after the cooking mode is selected, if the working state of the corresponding target temperature sensor is a normal state, the temperature of the induction cooker can be directly monitored and processed through the sensing data of the target temperature sensor.

And S53, if the working state of the target temperature sensor is a fault state, determining a new target temperature sensor, and carrying out temperature monitoring processing on the induction cooker according to the sensing data of the new target temperature sensor.

After the cooking mode is selected, if the working state of the corresponding target temperature sensor is a fault state, the temperature measurement of the target temperature sensor is inaccurate, and the target temperature sensor is not suitable for monitoring the temperature of the induction cooker according to the target temperature sensor. Therefore, a new target temperature sensor needs to be determined, and the temperature monitoring processing is performed on the induction cooker through the sensing data of the new target temperature sensor.

Specifically, when the target temperature sensor is the first temperature sensor, if the operating state of the second temperature sensor is a normal state, it is determined that the new target temperature sensor is the second temperature sensor.

The first temperature sensor is arranged at the bottom of the panel of the induction cooker and can directly measure the temperature of the panel of the induction cooker. The second temperature sensor is a temperature sensor arranged at the bottom of the pot, and can directly measure the temperature at the bottom of the pot. When the first temperature sensor is in a fault state, the temperature control of the system can be carried out through the second temperature sensor.

And when the target temperature sensor is the second temperature sensor, if the working state of the first temperature sensor is a normal state, determining that the new target temperature sensor is the first temperature sensor.

The first temperature sensor directly measures the temperature of the panel of the induction cooker, and can indirectly measure the temperature of the bottom of the cookware. Similarly, therefore, when the second temperature sensor is in a fault state, temperature measurement of the system can be performed by the first temperature sensor.

And when the target temperature sensor is the steam temperature sensor, if the working state of the second temperature sensor is a normal state, determining that the new target temperature sensor is the second temperature sensor.

The steam temperature sensor directly measures the temperature of steam in the cooker, and when the steam temperature sensor is in a fault state, the temperature of the system can be measured through the second temperature sensor.

When the temperature sensors in the system are all in a fault state, the temperature measurement of each temperature sensor is inaccurate, and at the moment, in order to ensure safety, the induction cooker can be controlled to be shut down and an alarm is given to remind a user.

In practice, the working state of each temperature sensor can be judged at intervals. If the temperature sensor in the fault state recovers to be normal in the later period, the fault state can be eliminated, and the temperature sensor can still be used for temperature monitoring.

When the induction cooker is in the non-precise control mode, the cooker above the induction cooker panel is indicated to be a common cooker, a temperature sensor is not arranged in the cooker, only the bottom of the induction cooker panel is provided with a first temperature sensor, and the first temperature sensor can directly measure the temperature of the induction cooker panel.

If the working state of the first temperature sensor is a normal state, carrying out temperature monitoring processing on the induction cooker through the sensing number of the first temperature sensor; if the working state of the first temperature sensor is a fault state, the first temperature sensor indicates that no temperature sensor in a normal state exists in the system, and the induction cooker is controlled to be shut down at the moment.
