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.

The terms "first," "second," and the like in the description and in the claims, and in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Before describing embodiments of the present application, the terms and background of the present application will be explained.

Cookers, also known as cookware. The cooking utensils are mainly used for kitchen cooking, and are divided into different types according to different use conditions, and the specific types can be as follows:

the method is divided into the following steps according to the used gas species: natural gas stoves, artificial gas stoves, liquefied petroleum gas stoves, electromagnetic stoves;

the material composition is as follows: there are cast iron stove, stainless steel stove, enamel stove;

the method is divided into the following steps according to cooking range: single-hole, double-hole, multi-hole;

the ignition method comprises the following steps: an electric pulse-dissecting ignition stove and a piezoelectric ceramic ignition stove;

the installation mode is divided into: desk-top stoves, built-in stoves.

With the continuous development of science and technology, intelligent cooking utensils have gradually come into the life of users. Because the life of the user is busy, the user often needs to make a call while cooking, do housework, take care of the baby and the like, and the intelligent cooker provides good help at the moment. For example, some cookers have a function of a one-key stir-frying flow control valve body, and the flow valve body is closed by using a pre-written control logic to achieve the effect of exiting a stir-frying mode at regular time or by detecting temperature change, so that a user can do other things in the cooking process without worrying about other accidents such as dry burning, forgetting to close gas and the like of the cooker.

However, in practical applications, after a valve closing signal is output to the flow valve body, it cannot be determined whether the flow valve body performs the valve closing operation, and if the flow valve body fails to close the valve, the range may have a potential safety hazard, and dangerous accidents such as dry burning or gas leakage may occur.

Based on the technical problems in the prior art, the design concept of the inventor is as follows: the inventor finds that when the cooker is actually used, the valve body of the cooker can be detected in real time by adding a detection device, so as to judge whether the valve body performs valve closing operation, and the problem that the valve body does not relate to a valve can be solved to a great extent.

Hereinafter, the technical means of the present application will be described in detail by the following specific examples. It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

In the working process of the cooker, the valve body control module 11 is used for sending a closing instruction to the valve body 13 when detecting that a preset fire shutting condition is met. At this time, when the valve body 13 receives a closing command transmitted from the valve body control module 11, the valve body 13 is used to control the gas flow rate of the burner 14.

Further, the valve body detection module 12 is configured to detect an opening and closing operation of the valve body 13, and specifically, the valve body detection module 12 is configured to detect a state of the valve body 13 according to a closing instruction sent by the valve body control module 11. If the valve body detection module 12 detects that the valve body 13 is not closed, the valve body detection module 12 is further configured to control the valve body control module 11 to forcibly close the valve body 13.

In one specific implementation, the valve body detection module 12 includes a displacement sensor or an angle sensor. Taking an angle sensor as an example, in practical applications, the angle sensor is used for detecting a rotation angle of the valve body 13, so as to determine the state of the valve body 13.

It should be noted that the valve body 13 is a regulating valve capable of increasing or decreasing the flow rate, and may be a flow rate valve body, which is not limited herein.

Optionally, the valve body detection module 12 is configured to send a forced closing instruction to the valve body control module 11 when detecting that the valve body 13 is not closed;

Optionally, the valve body detection module 12 is configured to detect a state of the valve body 13 according to a closing instruction, specifically:

valve body detection module 12 is specifically used for:

the valve body detection module 12 detects the opening and closing actions of the valve body 13 after detecting the closing command;

if the valve element 13 is not closed within a predetermined time period, it is determined that the valve element 13 is not closed.

Optionally, before the valve body detection module 12 is configured to detect the state of the valve body 13 according to the closing instruction, the valve body control module 11 is further configured to:

the valve body control module 11 sends a closing command to the valve body 13 and sends a closing command to the valve body detection module 12.

It should be noted that the division of the valve body control module 11 and the valve body detection module 12 in the above cooking bench is only a division of logical functions, and all or part of the division may be integrated into one physical entity or may be physically separated in actual implementation. And these modules can be realized in the form of software called by processing element; or may be implemented entirely in hardware; and part of the modules can be realized in the form of calling software by the processing element, and part of the modules can be realized in the form of hardware.

The fire-stopping control method is applied to the kitchen range, and as shown in fig. 2, the fire-stopping control method comprises the following steps:

and step 21, the valve body control module sends a closing instruction to the valve body when detecting that the preset fire-shutting condition is met.

In this step, in the process of actually applying the cooking bench, for the user, according to the need of cooking, a preset fire-off condition may be removed, and the preset fire-off condition includes: the preset program execution time reaches a preset duration, or the temperature of the burner reaches a preset value.

Specifically, the preset time duration may be a time duration set on the cooking bench by a user, or may be a time duration of the cooking bench in a certain cooking mode, for example, in the cooking mode of cooking, the cooking bench is required to work for 30 minutes, and at this time, the burner may be turned off; the temperature reaching the preset value may be a temperature set on the cooking bench by a user, or a temperature threshold of the cooking bench in a certain cooking mode, or a maximum heat resistance value of the cooking bench, for example, the temperature needing to be stir-fried reaches 150 degrees in a stir-frying cooking mode.

Optionally, the preset time and the preset temperature may be determined according to actual conditions.

Optionally, when the valve body control module detects that the preset program execution time reaches the preset duration, or the temperature of the burner reaches the preset value, a closing instruction is sent to the valve body to instruct to close the valve body and exit from a certain cooking mode.

And step 22, the valve body detection module detects the state of the valve body according to the closing instruction.

Before this step, the valve body control module sends a closing instruction to the valve body detection module while sending a closing instruction to the valve body.

Optionally, the time that the valve body detection module needs to detect whether the valve body is closed can be determined by the time that the valve body control module sends the closing instruction, so that when the valve body control module detects that the preset fire closing condition is met, the valve body control module sends the closing instruction to the valve body detection module while sending the closing instruction to the valve body.

In this step, the valve body detection module detects the opening and closing operation of the valve body after detecting the closing command. And if the valve body does not perform closing action within the preset time period, determining that the state of the valve body is not closed.

Optionally, the preset time period may be 0.5s, which is only an example here, that is, after the valve body detection module detects the closing instruction, if the time period of 0.5s elapses, the valve body detection module detects that the valve body does not perform a closing action (the valve body is not closed), it is determined that the state of the valve body is not closed.

And 23, if the valve body detection module detects that the valve body is not closed, the valve body detection module controls the valve body control module to forcibly close the valve body.

In this step, the valve body detection module detects that the state of the valve body is not closed, and in order to prevent the occurrence of dry burning on the cooking bench or the occurrence of a situation that does not meet the purpose of a certain cooking mode, the valve body control module is required to forcibly close the valve body.

In one possible implementation, if the valve body detection module detects that the valve body is not closed, a forced closing instruction is sent to the valve body control module; and the valve body control module forcibly closes the valve body according to the forcible closing instruction.

The fire-shutting control method of the cooker provided by the embodiment of the application is applied to the cooker comprising a valve body control module, a valve body detection module, a valve body and a combustor. According to the method, when the valve body control module detects that the preset fire shutting condition is met, a closing instruction is sent to the valve body. And then the valve body detection module detects the state of the valve body according to the closing instruction, and if the valve body detection module detects that the valve body is not closed, the valve body detection module controls the valve body control module to forcibly close the valve body. According to the method, the state of the valve body is detected through the valve body detection module, and the forced closing instruction is sent to the valve body control module, so that potential safety hazards which may occur when the valve body does not act on the closing instruction are avoided.

Fig. 3 is an overall flowchart of a fire-shutting control method for a cooking appliance provided in an embodiment of the present application. As shown in fig. 3, when the preset fire-shutting condition is satisfied, the fire-shutting control method includes the steps of:

step 1, starting;

step 2, the valve body control module detects whether a preset fire-off condition is met, and if yes, the step 2 is executed; if not, executing the step 11;

step 4, the valve body control module sends a closing instruction to the valve body detection module;

step 5, the valve body detection module receives a closing instruction from the valve body control module;

9, the valve body control module receives a forced closing instruction from the valve body detection module;

The method closes the valve body under the condition of meeting the preset fire-off condition, and ensures the use safety of the stove.
