When the cooking device controls the stirring shovel 121 and the auxiliary shovel 122 to move, the stirring shovel 121 and the auxiliary shovel 122 move under the driving of the revolution shaft 126.

The predetermined area may be a predetermined angle A, in FIG. 2B, AX being the axis of the cantilever 130, C being the center of the shaft 126, and the angle A being the extent of the deflection to either side along the edge of the pot, centered at C-D2. In an embodiment of the present disclosure, the angle a may be in a range of 30 degrees to 40 degrees. Preferably, the angle a may be 35 degrees.

Fig. 2C is a flowchart of a pot cover control method of a cooking apparatus according to an embodiment of the present invention, as shown in fig. 2C, the method includes the following steps:
201. and acquiring a Hall voltage signal output by the Hall voltage detection device.
202. And under the condition that the Hall voltage meets a preset condition, determining that the auxiliary shovel is positioned at a preset position and controlling the cooking equipment to perform corresponding operation on the pot cover.
In the embodiment of the invention, when the cover of the cooking device is required after the cooking is finished, before the cover of the cooking device is controlled to be opened, whether the auxiliary shovel is located in a safe area or not can be confirmed, and if the auxiliary shovel is located in the safe area, the cooking device can be controlled to open the cover of the pot.
In another embodiment, if the auxiliary shovel is in the unsafe area, the auxiliary shovel is controlled to continue to move for a preset time period until the auxiliary shovel is determined to be in the safe area, and then the cooking device is controlled to perform the uncovering operation on the pot cover.
In the embodiment of the invention, the position of the stirring shovel can be detected through the Hall voltage detection device.
Particularly, can set up the magnet in the stirring shovel, set up hall voltage detection device in the pot cover, the pot body is fixed, and stirring shovel and supplementary shovel relatively fixed, when stirring shovel and supplementary shovel are at the internal motion of pot, the distance between the hall voltage detection device in the magnet in the stirring shovel and the pot body can change correspondingly. The magnetic field felt by the hall voltage detecting means is stronger as the magnet is closer to the hall voltage detecting means, and weaker as the magnet is farther from the hall voltage detecting means. The Hall voltage signal output by the Hall voltage detection device can change along with the strength change of the magnetic field, the stronger the magnetic field is, the larger the Hall voltage signal is, and the weaker the magnetic field is, the smaller the Hall voltage signal is. Based on this, can judge the position of stirring shovel according to the size of hall voltage signal. According to the relative position relation of the stirring shovel and the auxiliary shovel, under the condition that the cooking equipment controls the stirring shovel and the auxiliary shovel to move and determine, the position of the corresponding auxiliary shovel is relatively determined, so that the position of the auxiliary shovel can be determined according to the position of the stirring shovel.
Fig. 3 is a schematic diagram showing the connection relationship between the hall voltage detecting device and the processor. The processor may provide a power signal and a ground signal, shown in the figure as 5V and GND, to the hall voltage detection device. When the processor provides a power signal and a ground signal for the hall voltage detection device, the hall voltage detection device can work normally, that is, the hall voltage detection device can output a corresponding hall voltage signal according to the detected change of the distance of the magnet relative to the hall voltage detection device.
Fig. 4 shows a schematic circuit diagram of a main control circuit, which may include a resistor R58, a resistor R9, a capacitor C45, a transistor D9, an interface JP14, and an interface TEMP1, and their specification parameters are 10K, NC, 0.1uF/50V, SES0511D3, GH-3AWT, and TP in sequence. In the figure, 3V3 and 5V represent power signals, GND represents ground signals, and HALL2 ADC represents external signals.
Fig. 5 shows a schematic circuit diagram of a hall voltage detection device, and the circuit of the hall voltage detection device may include a chip U1 and an interface JP1, and specification parameters of the chip U1 and the interface JP1 are ABK1360 and PHS-3A in sequence.
In practical application, when the stirring shovel and the auxiliary shovel move under the driving of the revolution shaft, wherein the stirring shovel moves to the farthest distance from the Hall detection device, the distance between the magnet and the Hall detection device is also the farthest, and the Hall voltage is V1; when the stirring shovel moves to the nearest distance from the Hall detection device, the distance between the magnet and the Hall detection device is also the nearest, the Hall voltage is V2, and the Hall voltage signal changes between V1-V2.
In practical application, can confirm the position of uncapping for supplementary shovel in safe area, according to the relatively fixed relation of supplementary shovel and stirring shovel, and then confirm that the hall voltage detection device that the stirring shovel position of uncapping corresponds lays the initial point, it is corresponding, set up hall voltage detection device on the position that corresponds with the initial point, when guaranteeing that the stirring shovel is located the initial point position, hall voltage detection device can export maximum voltage, and when voltage reaches the maximum value, supplementary shovel is located safe region, stirring shovel and supplementary shovel all are located predetermined position. Based on this, when the hall voltage satisfies the output maximum voltage, namely when the voltage is V2, it is possible to confirm that the stirring shovel is located at the preset position, and further confirm that the auxiliary shovel is located at the uncapping position in the safety area. When the auxiliary shovel is positioned at the uncovering position, the uncovering of the cooking equipment is controlled, the auxiliary shovel and the pot body cannot interfere, and the effect of protecting the auxiliary shovel and the pot body is achieved.
In the specific implementation process, when the output voltage of the Hall voltage detection device is the maximum value, the stirring shovel is positioned at a fixed angle, and considering that the auxiliary shovel can control the opening of the cooking device in a safe area, a voltage threshold value V3 can be preset between V1 and V2, correspondingly, when the output voltage of the Hall voltage detection device is in a voltage range of V3 to V2, the auxiliary shovel is determined to be positioned in the safe area, therefore, the condition that the voltage output by the Hall voltage detection device is greater than or equal to the voltage threshold value V3 is taken as the condition that the stirring shovel is positioned at the preset position, and when the stirring shovel is positioned at the preset position, the auxiliary shovel is positioned in the safe area.
In another embodiment, the auxiliary shovel is located in an unsafe area, and the revolution shaft is controlled to continuously drive the stirring shovel and the auxiliary shovel to move. In combination with the above description of the safe region, when the voltage output by the hall voltage detection device is in the voltage range of V3-V2, the stirring shovel is located in the safe region, and correspondingly, when the voltage output by the hall voltage detection device is in the voltage range of V1-V3, the auxiliary shovel is determined to be located in the unsafe region. When the auxiliary shovel is located in an unsafe area, the revolution shaft is controlled to drive the stirring shovel and the auxiliary shovel to continue to move for a preset time and then the cover is opened.
In the case where the lid of the cooking apparatus needs to be opened, several methods of determining whether the stirring blade is located at a predetermined position are given below.
Alternatively, the process of determining whether the stirring blade is located at the predetermined position may be implemented as: collecting a plurality of Hall voltage sampling signals output by a Hall voltage detection device according to a preset sampling period; and under the condition that the plurality of Hall voltage sampling signals meet preset conditions, determining that the stirring shovel is located at a preset position.
Alternatively, the hall voltage detecting means is provided at a position corresponding to the preset position. Above-mentioned if a plurality of hall voltage sampling signal satisfy preset condition, then confirm that the stirring shovel is located the process of predetermineeing the position and can realize as: and if the plurality of Hall voltage sampling signals are larger than or equal to the Hall voltage sampling signals with the first set threshold value, determining that the stirring shovel is located at the preset position.
When hall voltage detection device set up on the position that corresponds with the preset position, the stirring shovel drives the magnet and rotates to preset position department, and magnet and hall voltage detection device's distance is nearest, and hall voltage sampling signal that can detect is the biggest, and when hall voltage sampling signal exceeded first preset threshold value, it was located the preset position to confirm the stirring shovel. As shown in fig. 6, which is a schematic waveform diagram of a hall voltage sampling signal, when the "bump" position of the waveform exceeds a first preset threshold value of 40V, it can be determined that the stirring blade is at a preset position.
As can be seen from fig. 6, the hall voltage sampling signals in a short period of time are all greater than the first preset threshold value 40V, and the stirring blade is considered to be located at the preset position in the period of time, but in practice, there is a deviation, that is, only a certain moment in the period of time is the moment when the stirring blade is actually located at the preset position, and the stirring blade determined at other moments is located at the preset position and has an error. To reduce this error, the first preset threshold may be adjusted upward to be infinitely close to the maximum value of the hall voltage sampling signal.
It can be understood that the actual hall voltage sampling signal fluctuates due to the influence of the operating environment. As shown in fig. 7, when the hall voltage sampling signal fluctuates with time, even if the stirring blade is located at the preset position, the collected hall voltage sampling signal is smaller than the first preset threshold, so that, in order to more accurately identify whether the stirring blade is located at the preset position, the embodiment of the present invention further provides a method for determining whether the stirring blade is located at the preset position.
Optionally, in a case that the variation trend of the plurality of hall voltage sampling signals satisfies a trend condition, it is determined that the stirring blade is located at the preset position.
According to the method for determining whether the stirring shovel is located at the preset position, not only is attention paid to whether the Hall voltage sampling signal is larger than a certain threshold value, but also the change trend of the Hall voltage sampling signal is observed, and whether the stirring shovel is located at the preset position is determined according to the change trend.
Optionally, in the above case that the variation trend of the plurality of hall voltage sampling signals satisfies the trend condition, the process of determining that the stirring blade is located at the preset position may be implemented as follows: and if the plurality of Hall voltage sampling signals are reduced after being sequentially increased along with the sampling period, determining that the stirring shovel is located at the preset position.
Assuming that the currently collected hall voltage signal is V1 and the previous hall voltage sampling signal is V2, when V1 is greater than V2, the currently collected hall voltage signal is considered to be continuously increased. In this way, erroneous determination due to fluctuation of the signal can be prevented.
It should be noted that, for the hall voltage detecting device, when different magnetic poles of the magnet face the hall voltage detecting device, the output waveform thereof is different. As shown in fig. 8, when the first magnetic pole (N pole or S pole) of the magnet faces the hall voltage detecting device, it outputs a waveform that is "convex", and when the second magnetic pole (S pole or N pole) of the magnet faces the hall voltage detecting device, it outputs a waveform that is "concave". The specific magnetic pole of the magnet faces the Hall voltage detection device, and what waveform the Hall voltage detection device outputs is determined by the specification of a chip in the Hall voltage detection device.
If it is difficult to guarantee which magnetic pole of magnet faces hall voltage detection device and installs, can also increase such judgement logic to when preventing the magnetic pole and adorning conversely, can't correctly judge whether the stirring shovel is located preset position: and if the plurality of Hall voltage sampling signals are increased after being sequentially reduced along with the sampling period, determining that the stirring shovel is located at the preset position.
By the method, when the magnetic pole is reversely arranged, even if the waveform is concave, whether the stirring shovel is positioned at the preset position can be determined according to the judging mode.
Due to the fact that the digital-to-analog signal converters in the processor have different sampling capacities, for some digital-to-analog signal converters with poor sampling capacities, the sampling deviation can cause the wave band which is originally in the climbing trend to be mistakenly considered to fall, and therefore the misjudgment that the stirring shovel is located at the preset position can be caused. In addition, because the stirring shovel can rotate and move up and down, the change of the distance is smaller relative to the change of the distance moving up and down during rotation, and when the stirring shovel moves up and down, if the distance between the magnet in the stirring shovel and the Hall voltage detection device is far away, the Hall voltage sampling signal collected by the Hall voltage detection device is weaker, and the misjudgment that the stirring shovel is positioned at the preset position can also be caused. In the third method for determining whether the stirring blade is located at the preset position provided by the embodiment of the invention, the above problem can be solved.
Optionally, if the variation trend of the plurality of hall voltage sampling signals satisfies the trend condition, the process of determining that the stirring blade is located at the preset position may be implemented as follows: if a first Hall voltage sampling signal, a second Hall voltage sampling signal and a third Hall voltage sampling signal in the plurality of Hall voltage sampling signals meet the following conditions, determining that the stirring shovel is located at a preset position, wherein the third Hall voltage sampling signal is the last collected Hall voltage sampling signal in the plurality of Hall voltage sampling signals:
a first difference value between the first Hall voltage sampling signal and the obtained minimum Hall voltage signal is greater than a first preset Hall voltage signal, and the first difference value is smaller than a second preset Hall voltage signal; a second difference value between the second Hall voltage sampling signal and the minimum Hall voltage signal is greater than a second preset Hall voltage signal, and the second difference value is smaller than a third preset Hall voltage signal; a third difference value between the third hall voltage sampling signal and the minimum hall voltage signal is greater than a third preset hall voltage signal; the first preset Hall voltage signal is smaller than the second preset Hall voltage signal, and the second preset Hall voltage signal is smaller than the third preset Hall voltage signal.
Or, if the variation trend of the plurality of hall voltage sampling signals satisfies the trend condition, the process of determining that the stirring shovel is located at the preset position can be realized as follows: if a fourth hall voltage sampling signal, a fifth hall voltage sampling signal and a sixth hall voltage sampling signal in the plurality of hall voltage sampling signals meet the following conditions, determining that the stirring shovel is located at a preset position, wherein the sixth hall voltage sampling signal is a hall voltage sampling signal obtained at the last in the plurality of hall voltage sampling signals:
a fourth difference value between the fourth Hall voltage sampling signal and the obtained maximum Hall voltage signal is greater than a fourth preset Hall voltage signal; a fifth difference value between the fifth hall voltage sampling signal and the maximum hall voltage signal is greater than a fifth preset hall voltage signal, and the fifth difference value is less than a fourth preset hall voltage signal; a sixth difference value between the sixth hall voltage sampling signal and the maximum hall voltage signal is greater than a sixth preset hall voltage signal, and the sixth difference value is less than a fifth preset hall voltage signal; the fourth preset Hall voltage signal is greater than the fifth preset Hall voltage signal, and the fifth preset Hall voltage signal is greater than the sixth preset Hall voltage signal.
The principles of the above two judgment methods are similar, and the second judgment method is also proposed to prevent the magnet from being reversely installed. The first judgment mode will be described in detail below, and the second judgment mode can be understood with reference to the description of the first judgment mode.
First, a minimum hall voltage signal can be obtained. The minimum hall voltage signal can be a preset value and can also be acquired in a real-time detection mode. If the Hall voltage sampling signal is acquired in a real-time detection mode, the Hall voltage sampling signal can be compared with the previous Hall voltage sampling signal every time when one Hall voltage sampling signal is acquired, and the smaller Hall voltage sampling signal which is compared every time is recorded as the minimum Hall voltage signal.
Then, when a hall voltage sampling signal is acquired each time, the minimum hall voltage signal can be subtracted from the currently acquired hall voltage sampling signal, and the obtained difference is compared with the first preset hall voltage signal, the second preset hall voltage signal and the third preset hall voltage signal.
If the difference value between the Hall voltage sampling signal and the minimum Hall voltage signal collected at a certain time is larger than a first preset Hall voltage signal, the first difference value is smaller than a second preset Hall voltage signal, the difference value between the Hall voltage sampling signal and the minimum Hall voltage signal collected at a certain time is larger than the second preset Hall voltage signal, the second difference value is smaller than a third preset Hall voltage signal, the difference value between the Hall voltage sampling signal and the minimum Hall voltage signal collected at a certain time is larger than the third preset Hall voltage signal, and once the difference value between the Hall voltage sampling signal and the minimum Hall voltage signal collected at a certain time is larger than the third preset Hall voltage signal, the stirring shovel can be determined to be located at a preset position.
For example, assume that the difference between the hall voltage sampling signal acquired at the 1 st time and the minimum hall voltage signal is denoted as Δ X1, the difference between the hall voltage sampling signal acquired at the 2 nd time and the minimum hall voltage signal is denoted as Δ X2, and the difference between the hall voltage sampling signal acquired at the 3 rd time and the minimum hall voltage signal is denoted as Δ X3. The first preset Hall voltage signal is recorded as A, the second preset Hall voltage signal is recorded as B, and the third preset Hall voltage signal is recorded as C. When the delta X1 is more than A, the delta X1 is less than B, the delta X2 is more than B, the delta X2 is less than C, and the delta X3 is more than C, the stirring shovel is located at a preset position.
The first preset hall voltage signal, the second preset hall voltage signal, and the third preset hall voltage signal may be determined in such a manner that, as shown in fig. 9, three points A, B, C may be selected on the waveform on the rising side, then the aforementioned minimum hall voltage signal is subtracted from the hall voltage signal corresponding to the point a, the minimum hall voltage signal is subtracted from the hall voltage signal corresponding to the point B, and the minimum hall voltage signal is subtracted from the hall voltage signal corresponding to the point C, so as to sequentially obtain the first preset hall voltage signal, the second preset hall voltage signal, and the third preset hall voltage signal.
By adopting the invention, the change of the distance of the magnet arranged in the stirring shovel relative to the magnet can be determined through the Hall voltage signal output by the Hall voltage detection device, and then whether the stirring shovel is at the preset position can be determined. When the stirring shovel is in the preset position, the auxiliary shovel is located in the preset uncovering position, at the moment, the cover opening action of the cooking equipment can be controlled, the auxiliary shovel cannot interfere with the pot body, and the damage to the auxiliary shovel and the pot body is avoided.
When the stirring shovel is driven by the motor to move, whether the stirring shovel is located at the preset position can be detected through the following three modes.
Referring to fig. 6, assuming that the first preset threshold is 40V, the hall voltage sampling signal collected in a certain sampling period is 50V, and it is determined that the hall voltage sampling signal is greater than the first preset threshold, so that it can be determined that the stirring blade is located at the preset position.
