Description

Control method of cooking appliance, cooking appliance and computer storage medium

Technical Field

The present disclosure relates to the field of home appliances, and more particularly, to a method for controlling a cooking appliance, and a computer storage medium.

Background

Cooking appliances have been one of the household appliances indispensable at present. A user can perform various cooking operations such as cooking, cooking soup, stewing, and the like using the cooking appliance. The existing cooking utensil generally has two or more Temperature probes, such as NTC (Negative Temperature Coefficient) Temperature sensors, for measuring Temperature points of corresponding parts of food, and the MCU adjusts cooking power and time in the cooking process through the Temperature measured by each Temperature probe, thereby realizing a complete cooking process. However, the temperature probe and its circuit may be disconnected during the use process, and the resistance of the temperature probe is very large at low temperature, so that the temperature probe is easily judged to be open circuit at low temperature, and the cooking utensil generally needs to be heated for a period of time to increase the temperature in the pot and then to judge whether the open circuit is formed. Therefore, the ambient temperature in the cooking appliance follows the heating at normal temperature for a period of time and then is subjected to open circuit judgment, the user does not always need to wait for heating at normal temperature and can detect the temperature after the temperature probe is opened, the temperature measurement cannot be carried out if the temperature probe is opened, the user cannot be rapidly warned and is reminded to maintain and replace the temperature measurement probe, great inconvenience is brought to the use of the cooking appliance, and the reliability and the cooking efficiency of the cooking appliance are reduced.

Disclosure of Invention

A series of concepts in a simplified form are introduced in the content section of the application, which is described in further detail in the detailed description section. The summary of the present application is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to determine the scope of the claimed subject matter.

In a first aspect, an embodiment of the present application provides a control method for a cooking appliance, including:

before the cooking appliance is heated, judging whether the environmental temperature of the environment where the cooking appliance is located is greater than or equal to a preset temperature or not;

if the environment temperature is determined to be greater than or equal to the preset temperature, judging whether a temperature measuring device in the cooking appliance is normal;

and if the temperature measuring device is determined to be abnormal, alarming.

Therefore, when the environmental temperature is greater than or equal to the preset temperature (such as normal temperature), whether the temperature measuring device is normal or not is immediately judged, and heating is not needed first, so that whether the temperature measuring device can normally work or not is determined as soon as possible before the cooking appliance is heated, and the abnormal detection speed is increased; when the temperature measuring device is abnormal, the alarm is given in time to inform a user to maintain. The problem that the user misses the dining time due to delayed heating alarm is avoided while the situation that the false alarm and the open circuit of the temperature measuring device are reduced is guaranteed, and the reliability of the cooking appliance is improved.

In some embodiments, the method further comprises:

the temperature measuring device is arranged in the cooking appliance and is used for collecting the temperature in the cooking appliance to obtain at least one measured temperature;

determining the ambient temperature based on the at least one measured temperature.

In some embodiments, determining the ambient temperature based on the at least one measured temperature comprises:

when the at least one measured temperature comprises a measured temperature, taking the measured temperature as the ambient temperature;

when the at least one measured temperature comprises two measured temperatures, taking the higher measured temperature of the two measured temperatures as the ambient temperature;

when the at least one measured temperature includes at least three measured temperatures, a median or average of the three measured temperatures is taken as the ambient temperature.

Therefore, the environment temperature is determined based on the actual temperature collected by the temperature measuring device of the cooking appliance, the environment temperature can be ensured to be closer to the actual condition, and the accuracy of the determined environment temperature is improved.

In some embodiments, the preset temperature comprises: -5 ℃.

It can be seen that when the ambient temperature of the cooking appliance is less than-5 ℃, the temperature measuring device may be in a high resistance state due to too low temperature, thereby giving a false alarm and opening a circuit, and therefore, the cooking appliance needs to be heated for a period of time and then abnormal judgment is carried out; when the environmental temperature of the cooking utensil is higher than or equal to minus 5 ℃, the abnormity judgment of the temperature measuring device can be directly carried out, so that the abnormity judgment of the temperature measuring device can be carried out as fast as possible, and the alarm can be given in time.

In some embodiments, determining whether a temperature measuring device in the cooking appliance is normal comprises:

detecting the voltage of the temperature measuring device;

and if the voltage is the voltage of the working power supply or 0, determining that the temperature measuring device is abnormal.

Therefore, when the voltage of the temperature measuring device is equal to or close to the voltage of the working power supply or 0, the open circuit or short circuit abnormality of the temperature measuring device is shown, so that the abnormality of the temperature measuring device can be accurately judged, and the accuracy of subsequent alarm is ensured.

In some embodiments, the method further comprises:

if the environment temperature is lower than the preset temperature, heating the cooking appliance for a preset time, and then judging whether a temperature measuring device in the cooking appliance is normal or not;

and if the temperature measuring device is determined to be abnormal, alarming.

Therefore, when the ambient temperature is lower than the preset temperature, the ambient temperature is increased after the heating is carried out for a preset time, so that a false alarm open circuit caused by too low ambient temperature is avoided, the abnormity judgment of the temperature measuring device is carried out on the basis, and the abnormity judgment accuracy and the alarm accuracy are improved.

In a second aspect, an embodiment of the present application provides a cooking appliance, including:

The control module is used for judging whether the environmental temperature of the environment where the cooking appliance is located is greater than or equal to a preset temperature or not before the cooking appliance is heated; and

if the environment temperature is determined to be greater than or equal to the preset temperature, judging whether a temperature measuring device in the cooking appliance is normal or not;

and the alarm module is used for alarming if the temperature measuring device is determined to be abnormal.

Therefore, when the environmental temperature is greater than or equal to the preset temperature (such as normal temperature), whether the temperature measuring device is normal or not is immediately judged, heating is not needed first, and therefore whether the temperature measuring device can work normally or not is determined as soon as possible before the cooking appliance is heated, and the abnormal detection speed is increased; when the temperature measuring device is abnormal, the alarm is given in time to inform a user to maintain. The problem that the user misses the dining time due to delayed heating alarm is avoided while the situation that the false alarm and the open circuit of the temperature measuring device are reduced is guaranteed, and the reliability of the cooking appliance is improved.

In some embodiments, the cooking appliance further comprises:

the temperature detection module is used for being arranged on at least one temperature measuring device in the cooking appliance and acquiring the temperature in the cooking appliance to obtain at least one measured temperature;

The control module is further configured to determine the ambient temperature based on the at least one measured temperature.

In a third aspect, the present application provides a cooking appliance, including a memory, a processor, and a computer program stored on the memory and running on the processor, where the processor implements the steps of the method of the first aspect or any embodiment when executing the computer program.

In a fourth aspect, a computer storage medium is provided, on which a computer program is stored, which, when being executed by a processor, carries out the steps of the method according to the first aspect or any of the embodiments described above.

Therefore, when the ambient temperature is greater than or equal to the preset temperature, whether the temperature measuring device is normal or not is immediately judged, heating is not needed first, and therefore whether the temperature measuring device can work normally or not is determined as soon as possible before the cooking appliance is heated, and the speed of abnormal detection is increased; meanwhile, when the temperature measuring device is abnormal, the alarm is timely sent out to inform a user of maintenance. The problem that the user misses the dining time due to delayed heating alarm is avoided while the situation that the false alarm and the open circuit of the temperature measuring device are reduced is guaranteed, and the reliability of the cooking appliance is improved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, exemplary embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the described embodiments are only some embodiments of the present application and not all embodiments of the present application, and that the present application is not limited by the example embodiments described herein. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the application described in the application without inventive step, shall fall within the scope of protection of the application.

The embodiment of the application can be applied to cooking appliances, such as an electric cooker, an electric pressure cooker, a food processor, a soybean milk machine, an electric saucepan or other electric heating appliances.

Taking an electric cooker as an example, the cooking appliance may include a cooker body and a cover. The cooker body can be provided with an inner pot containing part in a cylindrical shape (or other shapes), and the inner pot can be freely placed into or taken out of the inner pot containing part, so that the inner pot is convenient to clean. The inner pot is generally made of a metal material and has a circular opening on an upper surface for containing a material to be heated, such as rice, soup, etc. For example, the inner pot may comprise a body of revolution formed by the pot walls with an upper opening and an inner cavity. The capacity of the inner pot is usually below 6L, for example, the capacity of the inner pot can be 2L or 4L.

The cover body is connected to the cooker body in an openable mode and used for covering the cooker body. The lid can include upper cover and removable lid, and removable lid sets up between the upper cover and a kind of deep pot body to be connected with upper cover detachably, in order to make things convenient for at any time to wash removable lid.

The cooking appliance may comprise control means for effecting cooking control of the cooking appliance. For example, the Control device may be a Micro Control Unit (MCU). The cooking appliance may further comprise heating means for heating the inner pot.

In addition, the cooker body can also comprise a power supply board, and a display board (also called as a panel) can be arranged on the cooker body. Wherein the power panel can be used for supplying power for a control device, a display panel and the like.

Optionally, the cooking appliance may comprise a communication module for enabling communication with other devices. Illustratively, the communication module may employ bluetooth, wireless fidelity (Wifi), cellular communication, and the like. The cooking appliance can be communicated with the mobile terminal and/or the cloud server and the like through the communication module.

It should be noted that although a partial structure of the cooking appliance is schematically described at this time, these lists are merely exemplary and cannot be regarded as a structural limitation of the cooking appliance of the embodiment of the present application.

The current cooking appliance needs to detect the temperature measuring devices inside the cooking appliance, such as the temperature measuring probe NTC and the open circuit of the circuit thereof, so as to ensure the normal work of the cooking appliance. In order to prevent the situation of false alarm of open circuit caused by the low temperature condition (because the resistance value of the temperature probe at low temperature is very large, the lower the temperature is, the larger the resistance value of the temperature probe is, when the temperature resistance value of the temperature probe is very large, the temperature probe is possibly misjudged to be in the open circuit state, and because the resistance value of the open circuit condition is very large), the temperature probe needs to be heated for a period of time, so that the resistance value begins to decrease after the temperature of the temperature probe rises, at the moment, the temperature probe is judged through the MCU, if the resistance value is not obviously decreased, the open circuit is considered, otherwise, the temperature probe and the circuit thereof are not opened, and cooking is not affected. The method judges that heating is needed for a period of time, and a user is not always beside a cooking appliance after cooking, so that cooking cannot be finished if a probe and a circuit thereof are partially opened, and poor user experience is caused because the user misses the dining time due to untimely reminding.

In view of the above, the present application provides a control method of a cooking appliance of an embodiment of the present application, which will be described below with reference to fig. 1. Referring to fig. 1, fig. 1 shows a schematic flow chart of a control method of a cooking appliance according to an embodiment of the present application. As shown in fig. 1, the method 100 is performed by a cooking appliance and includes:

s110, before the cooking appliance is heated, judging whether the environmental temperature of the environment where the cooking appliance is located is greater than or equal to a preset temperature or not;

s120, if the environment temperature is determined to be greater than or equal to the preset temperature, judging whether a temperature measuring device in the cooking appliance is normal;

s130, if the temperature measuring device is determined to be abnormal, alarming.

When the environmental temperature is higher than or equal to the preset temperature (such as normal temperature), whether the temperature measuring device is normal or not is immediately judged, and compared with the traditional method, the method does not need to heat firstly, so that whether the temperature measuring device can work normally or not is determined as soon as possible before the cooking appliance is heated, and the abnormal detection speed is increased; when the temperature measuring device is abnormal, the alarm is given in time to inform a user to maintain. The problem that the user misses the dining time due to delayed heating alarm is avoided while the situation that the false alarm and the open circuit of the temperature measuring device are reduced is guaranteed, and the reliability of the cooking appliance is improved.

Optionally, before S110 or in S110, the method further comprises:

Specifically, when a temperature measuring device a is arranged in the cooking appliance, and the temperature collected by the temperature measuring device is Ta, the control module determines that Ta is used as the ambient temperature and the preset temperature after obtaining the temperature Ta from the temperature measuring device a. When the cooking appliance is provided with 2 temperature measuring devices B and C, the collected temperatures are Tb and Tc respectively, the control module takes the larger one of Tb and Tc as the ambient temperature after acquiring the temperatures Tb and Tc from the temperature measuring devices B and C, if Tb is greater than Tc, the ambient temperature is determined to be Tb, otherwise, if Tb is less than Tc, the ambient temperature is determined to be Tc. When more temperature measuring devices D, E, F and … … (e.g., 3, 4, … …, etc.) are disposed in the cooking appliance, and the collected temperatures are Td, Te, Tf and … …, respectively, the control module obtains the temperatures Td, Te, Tf and … … from the temperature measuring devices D, E, F and … …, and then uses the median or average of Td, Te, Tf and … … as the ambient temperature, for example, the median is taken as an example, and when the temperatures collected by the 3 temperature measuring devices of the cooking appliance are Td < Te < Tf, the median Te can be used as the ambient temperature.

In some embodiments, the temperature measuring device may be an NTC sensor.

Optionally, in step S110, the preset temperature includes: -5 ℃.

Optionally, in step S120, determining whether a temperature measuring device in the cooking appliance is normal includes:

detecting the voltage of the temperature measuring device;

In some embodiments, referring to fig. 2, fig. 2 illustrates an example of a voltage detection module according to an embodiment of the invention. As shown in fig. 2, one end of the resistor R1 is connected to the operating power Vcc, the other end of the resistor R1 is connected to one end of the resistor R2, the other end of the resistor R2 is grounded, and the filter capacitor C1 is connected in parallel with the resistor R2; the junction of resistor R1 and resistor R2 is connected to the AD Port (i.e., AD Port) of the control module, which senses the voltage across resistor R1 or resistor R2. If the resistor R1 is a temperature measuring device, such as a temperature measuring probe NTC sensor, the resistor R2 is a pull-down resistor, and if the control module detects that the voltage is 0 or (infinitely) close to 0 through the AD port, it is determined that the resistor R1 is open. If resistor R2 is a temperature sensing device, then resistor R1 is a pull-up resistor, and if the control module detects a voltage of Vcc or (infinitely) close to Vcc via the AD port, it determines that resistor R2 is open-circuited. Therefore, according to the voltage detection module shown in fig. 2, the resistor R1 may be replaced by a temperature measuring device, and the resistor R2 may be replaced by a temperature measuring device, so as to detect the voltage of the temperature measuring device in the cooking appliance, and determine whether the cooking appliance is abnormal.

In some embodiments, the resistance of the resistor R2 includes 3K Ω -10K Ω. Further, the resistance value of the resistor R2 is 5.1K Ω. The resistance value of the temperature measuring probe is about 5.1K at the temperature of 90 ℃, the voltage resolution is highest at the temperature of 90 ℃ when the temperature measuring probe is matched with the pull-down resistor R2 with the resistance value of 5.1K, and the accuracy of voltage detection can be further improved.

Optionally, in step S130, the alarm may be an audible and visual alarm (e.g., an indicator light and/or a corresponding abnormal code displayed on a display panel and/or a buzzer alarm, etc.) to remind the user of the abnormal temperature measurement device, or a prompt message may be sent to the smart terminal (e.g., a smart phone, a smart wearable device) of the user or an APP on the smart terminal to remind the user of the abnormal temperature measurement device of the cooking appliance.

It is understood that the cooking process may be started in any manner known before S110. After the cooking equipment is powered on, the user finishes preparation, and the cooking program is started by selecting the function and the food material taste through the interaction module.

In some embodiments, the user may manually add ingredients to the inner pan and select a desired cooking function, such as soup making, congee cooking, etc., to initiate a cooking program.

In some embodiments, the food material may be added to the inner pot by the adding device of the cooking appliance, and the cooking program may be started according to the cooking instruction of the user.

Wherein the user can directly operate on the display panel of the cooking appliance to start the cooking program. Alternatively, the user may input cooking instructions on a mobile terminal interconnected with the cooking appliance to enable remote control to initiate the cooking program.

It is understood that initiating a cooking program may refer to starting cooking according to a predefined cooking profile, and that the cooking profile defines the variation of power over time. The cooking program may comprise a number of different phases: a water absorption stage; a rapid heating-up stage; maintaining a boiling stage; and (5) stewing.

In some embodiments, referring to fig. 3, fig. 3 illustrates an example of a control method of a cooking appliance according to an embodiment of the present application. As shown in fig. 3, the method includes:

step S310, starting the function of the cooking appliance;

step S320, acquiring the temperature of the content part of the cooking appliance through a plurality of temperature probes arranged in the cooking appliance, so as to determine the ambient temperature; and judging whether the environmental temperature is lower than a preset temperature, such as-5 ℃;

step S330, if the environmental temperature is lower than the preset temperature, heating for a period of time, such as 20S-10 min; entering step S340;

Step S340, if the ambient temperature is not lower than the preset temperature, detecting whether the voltage of the temperature measuring device is close to 0 or Vcc through an AD Port of a control module MCU;

step S350, if the voltage of the temperature measuring device detected by the AD Port is close to 0 or Vcc, determining that the temperature measuring device is abnormal, and alarming to a user;

in step S360, if the voltage of the temperature measuring device detected by the AD Port is not close to 0 or Vcc, it is determined that the temperature measuring device is normal, and the function of the cooking appliance may be performed.

Therefore, when the ambient temperature is greater than or equal to the preset temperature, whether the temperature measuring device is normal or not is immediately judged, heating is not needed first, and therefore whether the temperature measuring device can work normally or not is determined as soon as possible before the cooking appliance is heated, and the speed of abnormal detection is increased; meanwhile, when the temperature measuring device is abnormal, the alarm is timely sent out to inform a user of maintenance. The problem that a user misses the dining time due to delayed heating alarm is solved while the situation that false alarm and open circuit of a temperature measuring device are reduced is guaranteed, and the reliability of the cooking utensil is improved.
