Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. 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 invention.
Example one
The embodiment of the invention provides a heating control method for an electric steamer.
The electric steamer can be used in places such as families, eating houses, dining halls, restaurants and the like, and can be used for steaming or stewing foods such as fishes and shrimps, poultry eggs, meat, wheaten foods and the like. Can also be used for quickly heating food and various other foods, and is a multipurpose cooking tool.
The electric steamer of this embodiment includes controller, the dish that generates heat, with this fuse and the temperature controller that generates heat a set series connection. The temperature controller is connected with the controller and used for detecting the temperature of the heating plate.
As shown in fig. 1, the heating control method includes:
step 101, in a first heating stage, heating with a first preset heating power.
In this embodiment, when the electric steamer is turned on to heat, the first heating stage is first performed to heat with a first preset heating power.
Step 102, if the heating duration of the first heating stage reaches the first duration, switching to a second heating stage, wherein the heating power of the second heating stage is greater than the first preset heating power.
In this embodiment, the off-time period of the thermostat is predetermined. Specifically, as shown in fig. 2, a curve a represents a temperature curve diagram of a heating plate heated by a high power in a dry burning process in the prior art, and a curve b represents a temperature curve diagram of a heating plate heated by a first preset heating power in a dry burning process in the present application. T is roff Indicating the fuse opening temperature, T woff Indicating the thermostat off temperature. Under the condition of dry heating, namely when no water exists in the pot, heating is carried out at a first preset heating power, and heating duration is timed. Because no water is in the pan, the temperature of the heating plate can be quickly raised to the temperature limiting temperature of the temperature controller, namely the cut-off temperature T, when the pan is dry-burned at the moment woff . The controller of the electric steamer can judge whether the temperature controller is disconnected, and if the temperature controller is disconnected, the disconnection time T at the moment is obtained Break-off 。
It should be noted here that the setting of the first preset heating power is obtained through a large amount of experimental data, the first preset heating power enables the maximum temperature that the heating plate can rush up to be less than the disconnection temperature of the fuse as shown in fig. 2 after the heating plate is heated for the disconnection duration under the dry-burning condition (at this time, the temperature controller is disconnected, and the heating plate cannot be continuously heated), so that the fuse cannot be disconnected after the temperature controller is disconnected, and the connection is continuously maintained. So that when the temperature of the heating plate is reduced to below the temperature limiting temperature of the fuse, and the temperature controller is recovered to be closed, the fuse is also kept connected, and the electric steamer can recover heating at the moment. Binding curve aAnd curve b, it can be known that, in the prior art, the heating is directly carried out at high power initially, the electric steamer is dried, even if the temperature controller is disconnected, the waste heat can also enable the temperature of the heating plate to be rushed up to the disconnection temperature T of the fuse roff 。
According to the analysis, the electric steamer can be longer than the disconnection time of the temperature controller in the first heating stage, namely the first time, so that whether the electric steamer is in a dry-burning state or not can be judged in the first heating stage, and due to the arrangement of the first heating power, even if the electric steamer is in a dry-burning state in the first heating stage, the waste heat can not rush to the disconnection temperature of the fuse due to the waste heat, namely the fuse can still be connected under the dry-burning condition, so that the product performance is improved while the product cost is not increased.
Here, the turn-off temperature of the thermostat may be 125 ℃, and the recovery temperature may be 100 ℃. Namely, the temperature controller is switched off when the temperature of the heating plate reaches 125 ℃, and is switched on when the temperature of the heating plate is reduced to 100 ℃ or below. The breaking temperature of the fuse can be 172 ℃, that is, the fuse is broken when the temperature of the heating plate reaches 172 ℃. It can be understood that, in practical application, the temperature controller and the fuse may be selected according to practical situations, and the embodiment is not limited thereto.
In some embodiments, the first time period may also be equal to the off time period, which indicates that the first preset heating power can be such that, in the case of dry burning, the heating plate is turned off only when being heated for the first time period to stop heating; and then, the temperature of the heating plate is continuously increased by the waste heat, the temperature increase rate of the waste heat is exponentially increased in the later stage of the dry-burning state and can be increased to the highest temperature point in a short time, and in order to prevent the maximum temperature of the heating plate which can be uprushed by the waste heat from being smaller than the disconnection temperature of the fuse, the maximum temperature of the waste heat can be reduced by controlling the first preset heating power in the later stage of the dry-burning state, for example, the first preheating power can be 10-50% of the rated power.
The first time length is equal to the disconnection time length, and the possibility that the temperature controller cannot be disconnected when the heating plate is heated for the first time length due to environmental factors exists.
However, the first time length should not be too long, otherwise, under normal cooking, steam cannot be generated quickly, and the cooking effect is affected, so in this embodiment, the first preset heating power is increased, the disconnection time length is further shortened, the disconnection time length is shortened, correspondingly, the first time length can also be shortened, and therefore the heating efficiency is improved, but considering the safety factor, the first time length should be longer than the disconnection time length, and it is ensured that the maximum temperature of the upward-rushing heating plate due to the waste heat is less than the disconnection temperature of the fuse in the dry-burning state.
The specific body can set the first time length to be 1.5 times, 2 times and the like of the disconnection time length, and the first time length is set to be a larger multiple type, such as 2 times, the temperature controller is disconnected when the first time length is heated to be half of the first time length, the temperature of the heating plate continues to rise due to the waste heat, and due to the fact that the temperature rising rate of the waste heat is exponentially increased in the later period of the dry burning state, the temperature rises to the highest temperature point in a short time, and therefore under the high probability, the highest temperature point of the waste heat can appear in the first time length range, and the safety of the dry burning can be guaranteed.
When the temperature is set to a small multiple, the highest temperature may occur after the first time period, and the heating efficiency may be higher and the safety factor may be relatively small. However, this scheme may be adopted in some embodiments of the present invention, and the safety of dry burning considered in this embodiment is a multiple scheme.
If water exists in the electric steamer body, namely the electric steamer is not in a dry-heating state, the heating time of the first heating stage reaches the first time, the first heating stage is ended, and the electric steamer is switched to the second heating stage, specifically, the heating power is switched. The first heating power is switched to the heating power corresponding to the second heating stage. The heating power of the second heating stage is larger than the first preset heating power. The method comprises the following steps of firstly heating with low power in a first heating stage to judge dry heating, judging that the temperature controller is not disconnected if the first heating stage is carried out smoothly, and indicating that no dry heating exists, wherein water exists in the electric steamer pot body at the moment, and then entering a second heating stage after the first heating stage is finished, wherein the second heating stage can be understood as high-power heating so as to quickly heat the water in the pot body to boiling.
In some preferred implementations of this embodiment, as shown in fig. 3, the method further includes:
and 103, detecting the working state of the temperature controller.
In this implementation, the controller of the electric steamer can also detect the working state of the temperature controller. Specifically, the controller may determine an operating state of the thermostat according to the received level signal. For example, if the signal is a low level signal, it indicates that the thermostat is in an off state, and if the signal is a high level signal, it indicates that the thermostat is in an on state.
And step 104, if the temperature controller is in a disconnected state, prompting alarm information.
If the controller detects that the temperature controller is in a disconnected state, alarm information can be prompted to remind a user that the temperature controller is in a dry-heating state at the moment or to remind the user to add water into the pot. Specifically, for example, the controller may activate the sound alarm device of the electric steamer to emit a sound signal, or activate the light alarm device of the electric steamer to emit a light signal, or may also activate the sound and light alarm state of the electric steamer to emit a sound and light signal.
In a preferred implementation manner of this embodiment, as shown in fig. 4, the heating control method further includes:
step 105, determining whether indication information representing cancellation alarm information is received;
in the implementation mode, when the electric steamer sends alarm information to remind a user that the electric steamer is in a dry-cooking state at the moment, and water needs to be added into the pot, the user can manually cancel the alarm information of the alarm device after adding water into the pot, or when the water level detection device in the electric steamer detects that water exists in the pot, the water level detection device sends indication information representing the cancellation of the alarm information to the controller.
And 106, if the indication information is received and the current temperature controller is in a conducting state, restarting heating.
If the controller receives the indication information and judges that the current temperature controller is in a conducting state, the heating can be restarted, namely, the heating plate is powered again to heat the heating plate.
In this implementation, its dish that generates heat just can the resumeing heating after alarm information eliminates, otherwise unable resumeing heating to can avoid electric steamer repeated dry combustion method many times, guarantee product safety in utilization.
In some preferred implementations of this embodiment, the heating control method further includes: and if the heating time of the second heating stage reaches the second time, switching to a third heating stage, wherein the heating power of the third heating stage is less than that of the second heating stage. And if the heating time of the third heating stage reaches the third heating time, switching to a fourth heating stage, wherein the heating power of the fourth heating stage is less than that of the third heating stage. And in the final heating stage, heating at a second preset heating power until the cooking is finished. Wherein the second preset heating power is smaller than the heating power of the previous heating stage of the final cooking stage.
For better illustration, in conjunction with fig. 5, in the first heating phase, heating is performed at a first preset heating power P4, and the first time period is t1 (the timing may be accumulated from 0 to t 1). When the first heating stage is finished and no dry burning phenomenon exists, the normal heating is indicated, and the second heating stage is entered. And heating at power P1 in the second heating stage, wherein the power P1 is high-power heating and is greater than the heating power P1 in the first stage so as to quickly boil the water. When the heating time of the second heating stage reaches the second time t2 (the timing can be accumulated from 0 to t 2), a third heating stage is entered, heating is carried out at the power P2 in the third heating stage, and P1 is less than P1. When the heating time of the third heating stage reaches t3 (the timing can be accumulated from 0 to t 3), the fourth heating stage is entered, heating is performed at power P3 in the fourth heating stage, P3 is less than P2, when the heating time of the fourth heating stage reaches t4 (the timing can be accumulated from 0 to t 4), the final heating stage is entered, heating is performed at second heating power P4 until the cooking is finished, and P4 is less than P3. It should be noted that one or more heating stages may be further disposed between the final heating stage and the fourth heating stage according to practical situations, and the embodiment is not limited thereto.
As can be seen from the above description, in this implementation manner, the first heating stage is a stage of determining whether to dry heat, the second heating stage is a high-power heating stage, and after the second heating stage to the final heating stage, for reducing power for heating, the heating power is reduced in a stepwise manner, so that energy consumption can be saved while the cooking effect is ensured.
The heating control method for the electric steamer can judge the dry burning condition of the electric steamer in the first heating stage, and the first heating stage can ensure that the fuse is not disconnected during dry burning, so that the electric steamer can judge the dry burning condition firstly when in use, and the fuse is not disconnected even if the electric steamer is used, and if the electric steamer is not used, the electric steamer enters the high-power heating stage again to improve the product performance.
