Referring to fig. 2, fig. 2 is a first embodiment of a control method of an electric heating furnace according to the present invention, the control method of the electric heating furnace comprising the steps of:
s10, acquiring the current operation control state of the electric heating furnace on the object to be detected, wherein the operation control state is divided into a heating control state and a power-off state;
s20, if the operation control state is in the heating control state, acquiring a gravity acceleration change value of the object to be detected acting on the surface of the electric heating furnace;
and S30, controlling the heating power of the electric heating furnace according to the gravity acceleration change value.
In the embodiment of the invention, for convenience of distinguishing and understanding, the object to be detected is uniformly placed on the surface of the electric heating furnace to heat a container such as a kettle containing contents. The electric heating furnace generally has various heating functions, and users can select different heating modes according to different requirements, such as scented tea, cubilose, BB porridge, sweetmeats, bone soup, water-proof stewing, warm cups and the like. After the kettle body is placed on the surface of the electric heating furnace, in general, after the kettle body is electrified, a user selects one of the heating modes, the electric heating furnace starts to heat the kettle body, and at the moment, the operation control state of the electric heating furnace is in the heating control state.
During the heating process, the temperature of the content (generally water or other food containing water) in the kettle is increased continuously, the kinetic energy of the content is increased due to the temperature increase, the content vibrates in the gravity direction due to the kinetic energy increase, the physical expression is that the gravity acceleration changes, and particularly, the water begins to bubble when the kettle is close to a boiling state, and the change is very obvious. According to the method, the gravity acceleration sensor arranged on the furnace surface is used for detecting the gravity acceleration change value, and then the heating power corresponding to the gravity acceleration change value obtained through current detection is matched in the database preset by the system, so that the control and adjustment of the heating power are realized.
According to the technical scheme, the current temperature state of the object to be detected (namely the object to be heated) is determined by acquiring the gravity acceleration change value of the object to be detected on the surface of the induction cooker under the heating control state of the electric heating furnace, so that the heating power of the electric heating furnace is adjusted, the multi-stage power adjustment in the heating process of the electric heating furnace is realized, the accuracy and the intelligent control level of the heating process of the electric heating furnace are improved, and the electric heating furnace is energy-saving and environment-friendly.
Referring to fig. 3, fig. 3 is a second embodiment of the method for controlling an electric heating furnace according to the present invention, and based on the first embodiment, step S30 includes:
s31, acquiring the instant temperature of the object to be detected according to the gravity acceleration value;
in this embodiment, the content in the kettle is heated, and then converted into kinetic energy, which is expressed as a change in acceleration value in the gravity direction, and the system obtains the change in acceleration value of gravity and then performs normalization processing, so that the change is mapped to the temperature of the content, that is, the instant temperature.
It should be noted that, in the process of normalizing the change value of the gravitational acceleration detected by the sensor, considering the system error factor, the instant temperature is usually a range value, i.e. the instant temperature value obtained by calculation is allowed to float up and down, the error range of the up-and-down floating is preset by the system, and the up-and-down floating value is usually 0.1-2 ℃.
And S32, controlling the heating power of the electric heating furnace according to the instant temperature.
In this embodiment, a database is preset in the electric heating furnace system, and target powers of the electric heating furnace for objects to be detected in different temperature sections are preset in the database, where the target power may be a determined point value or an interval value. And after the system acquires the instant temperature of the object to be detected, matching the target power corresponding to the instant temperature from the database, and adjusting the heating power to be consistent with the target power, thereby completing the control of the heating power of the electric heating furnace.
Referring to fig. 4, fig. 4 is a third embodiment of the control method of the electric heating furnace of the present invention, and based on the second embodiment, step S32 includes:
s321, acquiring a functional mode selected by a user;
as mentioned above, the electric heating stove generally has multiple heating functions, and the user can select different heating function modes according to different requirements, such as scented tea, cubilose, BB porridge, dessert, bone soup, water-proof stewing, warm cup and the like. For ease of understanding, the scenarios described in table 1 below are briefly enumerated.
TABLE 1 Preset scene parameters under different functional modes
S322, controlling the heating power of the electric heating furnace according to the function mode and the instant temperature.
Acquiring a target temperature interval, a target heating power interval, target heating time and a preset first temperature value corresponding to the function mode, wherein the target temperature interval, the target heating power interval and the target heating time are in one-to-one correspondence;
each functional mode is divided into one or more heating stages, each heating stage corresponds to a target temperature interval, a target heating power interval, a target heating time and a preset first temperature value, wherein the preset first temperature value is the maximum value of the target temperature interval. For example, when the functional mode is flower tea, three heating stages are correspondingly provided, namely a first stage, a second stage and a heat preservation stage. The first stage has a target temperature interval (100 ℃), a target heating power interval (big fire) and a target heating time (18min) which are uniquely corresponding, and at the moment, a preset first temperature value corresponding to the first stage is the target temperature interval, namely the preset first temperature value is 100 ℃. The second stage also has a unique corresponding target temperature interval (96-100 ℃), a target heating power interval (middle fire) and a target heating time (42min), and the preset first temperature value corresponding to the second stage is the maximum value of the target temperature interval, namely the preset first temperature value is 100 ℃. The heat preservation stage also has a target temperature interval (60 ℃), a target heating power interval (heat preservation) and a target heating time (10h) which are uniquely corresponding to each other, and at the moment, a preset first temperature value corresponding to the heat preservation stage is the target temperature interval, namely the preset first temperature value is 60 ℃.
According to different heating function modes, the heating power corresponding to the target heating power intervals in different heating stages is different. Taking the functional mode as an example of scented tea, the heating power corresponding to the target heating power interval of the first stage (big fire) can be set to be 140 ± 10W, the heating power corresponding to the target heating power interval of the second stage (middle fire) can be set to be 130 ± 10W, and the heating power corresponding to the target heating power interval of the third stage (heat preservation) can be set to be 30 ± 10W.
It should be particularly noted that the values corresponding to the target temperature interval, the target heating power interval, the target heating time and the preset first temperature value listed in the above table do not represent the values actually set by the system, and do not have a limiting effect on the target temperature interval, the target heating power interval, the target heating time and the preset first temperature value in the present application. The above heating power setting is also merely exemplary and is not limited to practical applications.
If the instant temperature is smaller than the preset first temperature value, acquiring the target temperature interval corresponding to the instant temperature;
and adjusting the heating power to the target heating power interval according to the target temperature interval.
In this embodiment, in order to clearly illustrate the temperature control process of the electric heating furnace, the scented tea is taken as an example in the functional mode. The object to be detected is arranged on the surface of the electric heating furnace, the heating is started, namely, the first stage is entered, the system heats with the power corresponding to the big fire, the temperature rises gradually along with the continuous acquisition of heat energy of the contents, but the preset first temperature value (namely 100 ℃) of the first stage is not reached, and therefore the object to be detected is always heated with the power corresponding to the big fire in the first stage.
If the instant temperature is greater than and/or equal to the preset first temperature value, acquiring the target heating time corresponding to the instant temperature;
and adjusting the heating power to the target heating power interval according to the target heating time.
When the system detects that the instant temperature of the object to be detected is 100 ℃, the target heating time corresponding to the instant temperature (100 ℃) is obtained and is equal to the target heating time (18min) of the first stage. It should be noted that, at this time, the system also needs to acquire the actual time used by the object to be detected when the instant temperature of the first stage reaches 100 ℃, and when the actual time used is less than the target heating time (18min) of the first stage, the heating is continued with the power corresponding to the intense fire of the first stage until the actual time used is equal to the target heating time (18 min). Then, the second stage is automatically entered, heating is carried out at the power corresponding to the middle fire, and the heating time of the second stage is equal to the target heating time (42min) corresponding to the second stage. And when the heating time of the second stage reaches 42min, automatically entering a heat preservation stage, heating at a power corresponding to heat preservation, wherein the heating time of the heat preservation stage meets the target heating time (10h) corresponding to the heat preservation stage.
Referring to fig. 5, fig. 5 shows a fourth embodiment of the method for controlling an electric heating furnace according to the present invention, wherein step S10 includes:
s11, acquiring a gravity acceleration value and an angular velocity value of the object to be detected acting on the furnace surface;
and S12, determining the operation control state of the electric heating furnace on the object to be detected according to the gravity acceleration value and the angular velocity value.
In this embodiment, the operation control state of the electric heating furnace is divided into a heating control state and a power-off state. The power-off state is divided into two conditions, on one hand, the electric heating furnace is in a natural power-off state under the condition that the electric heating furnace is not electrified; on the other hand, during the power-on operation of the electric heating furnace, the contact state of the surface of the electric heating furnace may be changed by artificial kettle lifting and placing operations or other unexpected conditions (such as inclination, oscillation and the like), so that the electric heating furnace is automatically powered off to enter a protection mode.
In the technical scheme of the invention, the influence of the change of the contact state on the surface of the electric heating furnace is reflected to two physical quantities, namely a gravity acceleration value and an angular velocity value. The gravity acceleration value is obtained through an acceleration sensor, the angular velocity value is obtained through an angular velocity sensor (such as a gyroscope), and the acceleration sensor and the angular velocity sensor are arranged on the surface, opposite to the electric heating furnace face where the kettle body is placed, of the electric heating furnace for monitoring the state of the electric heating furnace face in real time.
Specifically, the current state parameter of the object to be detected is obtained according to the gravitational acceleration value and the angular velocity value; and comparing the current state parameter with a target state parameter preset by a system, and determining the operation control state of the electric heating furnace on the object to be detected according to the comparison result.
The system normalizes the acquired gravity acceleration value and the acquired angular velocity value to obtain the current state parameter of the object to be detected, wherein the current state parameter is a point value.
If the current state parameter is equal to the target state parameter, determining that the operation control state is in the heating control state; and/or
And if the current state parameter is not equal to the target state parameter, determining that the operation control state is in the power-off state.
The target state parameter preset by the system can be a determined numerical value or an interval value, and the target state parameter divides the running state of the object to be detected into two states, namely a heating control state and a power-off state. Therefore, if the current state parameter is equal to the target state parameter or falls into the interval range of the target state parameter, the operation control state of the electric heating furnace for the object to be detected is judged to be in the heating control state; otherwise, if the current state parameter is not equal to the target state parameter or does not fall into the interval range of the target state parameter, the operation control state of the electric heating furnace to the object to be detected is judged to be in a power-off state, and at the moment, the system can be controlled to automatically power off to enter a protection mode.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
