Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be apparent that the described embodiments are only some embodiments of the present invention and not all embodiments of the present invention, and it should be understood that the present invention is not limited by the example embodiments described herein. Based on the embodiments of the invention described in the present application, all other embodiments that a person skilled in the art would have without inventive effort shall fall within the scope of the invention.
The embodiment of the invention can be applied to cooking appliances, such as electric rice cookers, electric pressure cookers, cooking machines, soymilk makers, electric stewpans or other electric heating appliances.
Taking an electric cooker as an example, the cooking appliance may include a cooker body and a cover body. The pot body can be provided with a cylindrical (or other) inner pot containing part, and the inner pot can be freely placed in or taken out from the inner pot containing part, so that the inner pot can be conveniently cleaned. The inner pot is typically made of a metallic material and has a circular opening in its upper surface for holding the material to be heated, such as rice, soup, etc. For example, the inner pan may include a body of revolution formed by a pan wall having an upper opening and an inner cavity. The capacity of the inner pot is usually 6L or less, for example, the capacity of the inner pot may be 2L or 4L or the like.
The cover body is connected to the cooker body in an openable and closable manner and is used for covering the cooker body. The cover body can include upper cover and removable lid, and removable lid sets up between upper cover and the a kind of deep pot body to with upper cover detachably connects, in order to conveniently wash removable lid at any time.
The cooking appliance may comprise control means for effecting cooking control of the cooking appliance. The control means may be, for example, a microprocessor unit (Micro Control Unit, MCU). The cooking appliance may further comprise a heating device for heating the inner pot. For example, the control means may control the heating means to start or stop heating.
In addition, the cooking appliance may also have a temperature sensor, for example a top temperature sensor provided in the upper cover and/or a bottom temperature sensor provided below the inner pot accommodation. The bottom temperature sensor and the top temperature sensor may be thermistors. The bottom temperature sensor and the top temperature sensor are both connected to the control device of the cooking appliance to feed back the sensed temperature signal to the control device after sensing the temperature of the inner pot, so that the control device can realize more accurate control of the cooking process based on the temperature signal. Wherein, when the inner pot is placed in the inner pot receiving part of the pot body, the bottom temperature sensor may sense the temperature of the bottom wall of the inner pot, for example, the bottom temperature sensor may be in direct or indirect contact with the bottom wall.
In addition, the cooker body can also comprise a power panel, and a display panel (also called a panel) can be arranged on the cooker body. The power panel may be used for supplying power to a control device, a display panel, etc.
It should be noted that although a part of the structure of the cooking appliance is schematically described herein, these lists are merely exemplary and are not intended as structural limitations on the cooking appliance of the embodiment of the present invention.
Devices such as a coil terminal or a relay for IH heating in a cooking appliance may also be referred to as high-current devices, and generally, the current on these high-current devices is large during the heating process of the cooking appliance. The circuit connected with the high-current device is connected by using fasteners such as screws, if the fasteners are loosened, the ignition phenomenon is easy to occur at the connecting position, and the continuous ignition can cause spontaneous combustion of nearby plastic parts.
In addition, in order to prevent excessive temperature rise caused by heating in the use process of the cooking utensil, in particular to prevent events such as spontaneous combustion of products caused by excessive temperature rise, one or more temperature measuring probes and a thermal-protection circuit can be arranged at the bottom or the side surface of the inner pot of the cooking utensil, and when the temperature measuring probes detect the excessive temperature, the thermal-protection circuit can be used for conducting breaking treatment, so that accidents are avoided. However, in some cases, only part of the parts will be excessively heated, and the temperature probe cannot detect the local temperature rise; or the temperature measuring probe is possibly invalid, and the phenomenon that part of the components are continuously heated up or even spontaneously burned can occur at the moment, so that the cooking utensil is damaged.
In order to at least partially solve the above problems, to prevent spontaneous combustion of the cooking appliance, a method of controlling cooking according to an embodiment of the present invention is proposed. The cooking apparatus of the embodiments of the present invention includes one or more gas sensors, which may be installed near the high current device or near the fastener for sensing the concentration of carbon monoxide (CO), for example.
A gas sensor is a transducer that converts a certain gas volume fraction into a corresponding electrical signal. The gas sensor in the present application may be a carbon monoxide sensor capable of detecting the concentration of carbon monoxide in the air surrounding it. Illustratively, a gas sensor may include a sensor for detecting an oxygenCarbon-conversion sensitive materials, such as noble metal Pd functionalized one-dimensional SnO prepared by hydrothermal method with biological material shaddock peel as template 2 Nanofiber materials, and the like. And the gas sensor is capable of outputting an electrical signal, for example, an output voltage or an output current, etc., thereby functioning to convert chemical energy into electrical energy.
The concentration of carbon monoxide may be expressed in percentage, or in terms of a specific content per cubic meter of air, or may be expressed in other forms, which is not limited in this application.
The gas sensor may be electrically connected to a control device in the cooking appliance, so that the control device may acquire detection data of the gas sensor, and further the control device may implement cooking control based on the detection data. Wherein the detection data may be the carbon monoxide concentration or, alternatively, the corresponding output electrical signal.
A method of controlling cooking according to an embodiment of the present invention is described below with reference to fig. 1 to 2. Fig. 1 is a schematic flow chart of a method for controlling cooking according to an embodiment of the present invention. The method shown in fig. 1 comprises the following steps:
s10, determining the concentration of carbon monoxide through a gas sensor arranged on the cooking appliance during cooking of the cooking appliance.
S20, judging whether the change of the carbon monoxide concentration meets the stop condition according to the continuously detected carbon monoxide concentrations.
And S30, stopping cooking when the change of the carbon monoxide concentration meets the stopping condition.
It can be appreciated that in the cooking process of the cooking appliance, the heating can be performed through the coil, the heating can cause internal temperature rise, and when no fault exists, the temperature rise can not cause excessive release of carbon monoxide, so that the concentration of the carbon monoxide is basically unchanged, and the cooking is not affected.
However, if the fastener as mentioned above is loosened, a spark phenomenon is easily generated at the joint. During the ignition, the increasing temperature at the ignition site may cause sparks to fall on nearby plastic parts, which soften slightly and begin to become partially carbonized, which, due to incomplete combustion, may produce carbon monoxide. The cooking appliance in the application is provided with a gas sensor near the fastener for detecting the carbon monoxide concentration.
For example, S10 may be performed by the control device, and in particular the control device may acquire the carbon monoxide concentration detected by the gas sensor from the gas sensor. Alternatively, the control device may detect an output electrical signal of the gas sensor and determine the carbon monoxide concentration from the output electrical signal. The output electrical signal may be an output voltage or an output current, which is not limited in this application. It will be appreciated that if the carbon monoxide concentration is varied, the electrical signal output from the gas sensor is varied.
The initial value of the carbon monoxide concentration may also be determined by the gas sensor, for example, before S10, in particular before the start of the cooking. It will be appreciated that normal atmosphere contains some amount of carbon monoxide and therefore this initial value may normally be non-zero, but relatively close to zero. In this application, this initial value is denoted as M0.
Illustratively, in S10, the carbon monoxide concentration may be periodically obtained, for example, one carbon monoxide concentration is obtained at intervals, so that a plurality of carbon monoxide concentrations can be obtained after a lapse of a period of time. Wherein the detection period (i.e. the period of time between each two) may be any value between 1 second and 300 seconds, for example may be 8 seconds.
For example, a plurality of carbon monoxide concentrations determined periodically may be stored sequentially, for example, as a sequence, or in a stack. Assume that during cooking, a plurality of carbon monoxide concentrations are sequentially collected as M1, M2, …, mn.
Illustratively, in S20, it may include: sequentially storing the periodically determined carbon monoxide concentrations; based on the plurality of carbon monoxide concentrations stored in time series, it is determined whether or not a change in the carbon monoxide concentration satisfies a stop condition.
As an example, the stop condition may be that the plurality of carbon monoxide concentrations are increasing. That is, M1< M2< M3< … < Mn is satisfied.
For example, the stop condition may be that the sequence of initial values and a plurality of carbon monoxide concentrations is increasing, i.e. M0< M1< M2< M3< … < Mn.
As another example, the stop condition may be that the last of the plurality of carbon monoxide concentrations is greater than or equal to the first threshold. Assuming that the first threshold is denoted Mth, the stop condition is Mn.gtoreq.Mth. It will be appreciated that this embodiment does not exclude that other carbon monoxide concentrations preceding the last carbon monoxide concentration also meet the stop condition, e.g. there may be M3. Gtoreq.Mth.
Illustratively, in S30, if it is determined that a stop condition is satisfied, for example, M1< M2< M3< … < Mn is satisfied or mn+.gtoreq.mth is satisfied, the heating device may be controlled to stop heating, avoiding an accident due to an excessive carbon monoxide concentration.
Specifically, if it is determined that the stop condition is satisfied, it is explained that a fault has occurred, further, after S30, it may include: and sending out alarm information to prompt a user to conduct fault investigation.
In the present application, if it is determined that the stop condition is satisfied, it may be determined that the occurred fault may be: (a) The fastener is loosened, the connecting part is continuously ignited to lead the nearby plastic parts to be melted and carbonized, and carbon monoxide is generated by incomplete combustion in the carbonization process; (b) The temperature probe fails, and the high temperature rise in the cooking utensil causes high temperature carbonization of part of the components to generate carbon monoxide; (c) The carbon monoxide concentration in the environment in which the cooking appliance is located increases, such as a gas leak in the home.
The cooking appliance may send out alarm information by means of an audible and visual alarm, or the cooking appliance may send alarm information to a mobile terminal interconnected with the cooking appliance, for example. The alarm information may include, among other things, the concentration of carbon monoxide, or may include an indication of an increase in the concentration of carbon monoxide. Then, after checking the alarm information, the user can check the fault, for example, the user can check whether the fault of the above (c) occurs, if so, the gas overhaul is performed timely so as not to cause larger fire faults. If the user determines that the fault of (c) does not exist, the fault of (a) or (b) is considered to occur, namely, part of hardware inside the cooking appliance is faulty, and maintenance is needed.
In one implementation, after S30, it may further include: acquiring a plurality of continuously detected standby carbon monoxide concentrations when the cooking appliance is in a standby state; and if the standby carbon monoxide concentrations meet the leakage condition, sending out prompt information, wherein the prompt information indicates that the fuel gas leaks.
The process of detecting the plurality of standby carbon monoxide concentrations is similar to the process of S10, and will not be repeated here.
Wherein the leak condition may be that the plurality of standby carbon monoxide concentrations are increasing, or the leak condition is that a last one of the plurality of carbon monoxide concentrations is greater than or equal to a second threshold.
Let the standby carbon monoxide concentrations be denoted as T1, T2, … Tn in order. The second threshold is denoted Tth. It will be appreciated that the leak condition may be that the sequence of multiple standby carbon monoxide concentrations is increasing, i.e. T1< T2< T3< … < Tn. Alternatively, the leak condition may be that the last of the plurality of standby carbon monoxide concentrations is greater than or equal to the second threshold, i.e., tn+.Tth. It will be appreciated that this embodiment does not exclude that other standby carbon monoxide concentrations preceding the last standby carbon monoxide concentration also meet the leakage condition, for example, T3. Gtoreq.Tth may be present.
It will be appreciated that the first threshold and the second threshold in the embodiment of the present invention may be equal or unequal, and may be mth=tth=1 mg/m as an example 3 。
When the cooking utensil is in a standby state, if the detected carbon monoxide concentration meets the leakage condition, the carbon monoxide concentration in the environment where the cooking utensil is located is increased, and the cooking utensil is generally placed in a kitchen, so that the gas leakage of the kitchen can be inferred, and prompt information can be sent at the moment, so that a user can process the gas quickly, and large accidents are prevented.
The prompt information may be an audible and visual alarm sent by the cooking appliance, or may be a prompt sent by the cooking appliance to a mobile terminal connected with the cooking appliance. Alternatively, the prompt may include an indication of gas leakage and/or may include a detected standby carbon monoxide concentration.
As another example, fig. 2 is another schematic flow chart of controlling cooking in an embodiment of the present invention.
After the cooking appliance is powered on, it is first in a standby state, at which time the standby carbon monoxide concentration can be detected. If the continuously detected standby carbon monoxide concentrations (expressed as T1, T2 and … Tn) meet the leakage condition, namely T1< T2< T3< … < Tn or Tn is more than or equal to Tth, determining that the fuel gas in the kitchen leaks, and sending prompt information for a user to timely process. Specifically, the user can overhaul the cooking utensils, prevents that the user from using accidents such as conflagration that arouses when the cooking utensils ignites, so can remind the user in time to investigation danger, avoid causing loss of property, threaten personal safety even.
If the continuously detected standby carbon monoxide concentrations (denoted as T1, T2, … Tn) do not meet the leakage condition, i.e. T1< T2< T3< … < Tn and Tn+.gth is not met, it is determined that no leakage of kitchen gas occurs. The cooking program may then be initiated according to the user's cooking instructions to enter a cooking state.
The carbon monoxide concentration may be detected during cooking by the cooking appliance. If a plurality of continuously detected carbon monoxide concentrations (denoted as M1, M2, … Mn) meet a stop condition, i.e. M1< M2< M3< … < Mn or Mn.gtoreq.Mth is met, it is determined that the cooking appliance is malfunctioning. It may be determined, for example, that a hardware failure has occurred, such as the failure of (a) or (b) described above, i.e., fastener loosening or temperature probe failure. At this time, the cooking process may be controlled to terminate, i.e., the heating is stopped; and can also send out alarm information so as to remind the user to repair the cooking utensil. Thus, spontaneous combustion caused by continuous cooking can be prevented, and property and personal safety are ensured.
If the continuously detected carbon monoxide concentrations (denoted as M1, M2, … Mn) do not meet the stop condition, then this indicates that there is no safety hazard and cooking is continued until the cooking process is completed.

judging whether the change of the carbon monoxide concentration meets a stop condition according to the continuously detected carbon monoxide concentrations;
when it is determined that the variation in the carbon monoxide concentration satisfies the stop condition, the cooking is stopped,
wherein the cooking utensil is an electric heating device,
the stop condition is that the plurality of carbon monoxide concentrations is increasing or the stop condition is that the last of the plurality of carbon monoxide concentrations is greater than or equal to a first threshold.
2. The method as recited in claim 1, further comprising:
and sending out alarm information to prompt a user to conduct fault investigation.
3. The method of claim 1, wherein determining the carbon monoxide concentration by a gas sensor mounted on the cooking appliance comprises:
detecting an output electrical signal of the gas sensor;
and determining the concentration of the carbon monoxide according to the output electric signal.
4. The method according to claim 1, wherein determining whether the change in carbon monoxide concentration satisfies a stop condition based on the plurality of continuously detected carbon monoxide concentrations comprises:
sequentially storing the periodically determined carbon monoxide concentrations;
based on the plurality of carbon monoxide concentrations stored in time series, it is determined whether or not a change in the carbon monoxide concentration satisfies a stop condition.
5. The method of claim 1, further comprising, prior to initiating cooking:
an initial value of the carbon monoxide concentration is determined by the gas sensor.
6. The method according to any one of claims 1 to 5, further comprising, after stopping cooking:
acquiring a plurality of continuously detected standby carbon monoxide concentrations when the cooking appliance is in a standby state;
and if the standby carbon monoxide concentrations meet the leakage condition, sending out prompt information, wherein the prompt information indicates that the fuel gas is leaked.
7. The method of claim 6, wherein the leak condition is that the plurality of standby carbon monoxide concentrations are increasing or the leak condition is that a last one of the plurality of carbon monoxide concentrations is greater than or equal to a second threshold.
8. A cooking appliance comprising a memory, a processor and a computer program stored on the memory and running on the processor, characterized in that the processor implements the steps of the method of any one of claims 1 to 7 when the computer program is executed.
