detailed description

The present invention will be further described in detail below with reference to the drawings and specific embodiments. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a full understanding of the invention, but the invention may be practiced otherwise than as described herein. Limitations of the embodiments.

The technical solution of the present invention mainly detects the exhaust signal of the cooking appliance, and adjusts the heating parameters of the heating device accordingly. Before describing the heating device and the corresponding cooking method proposed by the present invention, the structure of the cooking appliance will be briefly described:

In a preferred embodiment of the invention, the cooking appliance is preferably a conventional pressure cooker. Generally, the common pressure cooker and the heating device are separate, and the heating device may be a gas stove, an induction cooker or an electric baking pan. As shown in FIG. 1, the conventional pressure cooker 2 includes a pot body 21, and covers a lid 22 of the pot body 21. The pot body 21 and the lid 22 are provided with a handle 24 for gripping at one end in the radial direction. An exhaust valve (the exhaust valve in Fig. 1 is blocked by the weight 23) and a float valve (not shown in Fig. 1) are provided, and the float valve is exhausted in the initial air-stage of the ordinary pressure cooker 2, and the exhaust valve is covered. There is a weight 23, the exhaust valve is opened with an exhaust port in the axial direction, when the air pressure in the pot body 21 is greater than the weight of the weight 23 When the force is applied, the weight 23 is vertically jacked up, the gas in the pot body 21 is discharged along the exhaust passage, and the pressure in the pot body 21 is gradually decreased. After a period of exhausting, the air pressure in the pot body 21 is lower than that. When the pressure of the weight 23 is lowered, the weight 23 is lowered, and the ordinary pressure cooker 2 stops the exhaust, thereby completing the exhaust once. After a period of heating, the pressure in the pot 21 is again greater than the weight of the weight 23, and a new round of exhaust is started. In this embodiment, the exhaust gas signal generated when the weight cooker 23 rises and falls is detected by the sensor, thereby determining whether the exhaust valve is in the exhaust state.

It is worth noting that in the prior art, some of the exhaust valves of the common pressure cooker are provided with a plurality of radial exhaust ports, and once the pressure in the pot is greater than a preset value, the exhaust gas is continuously exhausted. Drive the weight around the exhaust valve until the food is cooked. This part of the ordinary pressure cooker is different from the conventional pressure cooker provided in this embodiment.

Under the same power conditions, the dwell time in the ordinary pressure cooker is proportional to the number of exhausts or the exhaust time of the ordinary pressure cooker. The more the exhaust pressure of the ordinary pressure cooker or the longer the exhaust gas length, the more the dwell time in the ordinary pressure cooker long. Based on this, the present invention proposes to determine the pressure holding time of the pressure cooker by counting the exhaust gas length or the number of exhaust times of the pressure cooker, and then adjusting the heating parameters (such as heating power) of the heating device according to the cooking program selected by the user. Program. Since different cooking programs correspond to different food materials, the technical solution of the present invention enables targeted cooking for different food materials, and realizes the function of automatic cooking. At the same time, the solution can also be applied to other cooking utensils that need to be vented during cooking.

Specifically, a heating apparatus according to an embodiment of the present invention includes: a heating unit for heating a cooking appliance; an exhaust gas detecting unit for detecting an exhaust signal of the cooking appliance; and an electric control board connected to The heating assembly and the exhaust gas detecting assembly are configured to count an exhaust gas duration or an exhaust gas number of the cooking appliance according to the exhaust gas signal detected by the exhaust gas detecting component, and according to a cooking program selected by a user The heating parameters of the heating assembly are adjusted to control the total duration of exhaust or total number of exhausts of the cooking appliance. Wherein, the heating parameters include: heating power.

It can be seen that the heating device proposed by the invention can automatically adjust the heating parameters of the heating component according to the cooking program selected by the user, so as to control the holding time of the cooking process, thereby realizing the function of automatic cooking and solving the user's cooking. Appliances, especially non-smart cooking utensils (such as ordinary pressure cookers), need to keep an eye on the working conditions of the cooking utensils, which not only saves the user's cooking time, but also assists the user (especially the lack of cooking experience) The user) is cooking, which greatly enhances the user experience.

As a preferred embodiment of the present invention, the electronic control board may have the structure as shown in FIG. 2 when implementing the above functions, and specifically includes: an exhaust gas judging module 201, an exhaust gas statistics module 202, an instruction receiving module 203, and heating parameter adjustment. Module 204.

The exhaust gas judging module 201 is configured to determine whether the cooking appliance generates exhaust gas according to the exhaust gas signal detected by the exhaust gas detecting component; the exhaust gas statistics module 202 is configured to determine at the exhaust gas judging module 201 After the cooking appliance is exhausted, counting the exhaust time or the number of exhausts of the cooking appliance; the command receiving module 203 is configured to receive a cooking program selected by the user; and the heating parameter adjusting module 204 is configured to select according to the user The cooking program adjusts the heating parameters of the heating assembly to control the total duration of exhaust or the total number of exhausts of the cooking appliance.

Since different cooking procedures have different dwell times, for example, the dwell time corresponding to the cooking process and the soup process is different, and the dwell time is positively related to the number of exhausts of the cooking appliance or the exhaust time, that is, cooking. The greater the number of exhausts of the appliance or the longer the exhaust duration, the longer the dwell time. Therefore, the heating parameter adjustment module 204 is specifically configured to: determine the target of the cooking appliance according to the duration of the holding pressure corresponding to the cooking program selected by the user. The duration of the exhaust or the number of target exhausts; the heating parameters of the heating assembly are adjusted according to the target exhaust duration or the number of target exhausts.

Specifically, the heating parameter adjustment module 204 reaches the target exhaust time duration when the total exhaust time of the cooking appliance reaches the target exhaust time, or decreases the heating component after the total number of exhausts of the cooking appliance reaches the target exhaust number heating power.

In order to further illustrate the technical solution of the present invention, the technical solution of the present invention will be further described below by taking a heating device as an induction cooker and a cooking appliance as an ordinary pressure cooker shown in FIG. 1 as an example.

As shown in FIG. 1, the induction cooker 1 has an exhaust gas detecting assembly 11 and an electric control panel, and a coil disk for heating the ordinary pressure cooker 2 (not shown, the coil disk is a heating component), and supports a common pressure cooker. The panel 13 of 2 and the bottom cover for accommodating the coil disk and the electric control board.

The exhaust gas detecting component 11 includes a combination of one or more of a temperature sensor, an acoustic sensor, a vibration sensor, a humidity sensor, and an image detecting module. The exhaust gas detecting component 11 senses a temperature signal during the exhaust process of the common pressure cooker 2, The change of the sound signal, the vibration signal, the humidity signal, the image signal, etc., detects whether the ordinary pressure cooker 2 is exhausted, and transmits the exhaust signal to the electric control board of the induction cooker 1, and the electronic control board counts the exhaust of the ordinary pressure cooker 2 accordingly The number of times or the length of the exhaust gas, in order to control the amount of firepower of the induction cooker 1, the exhaust gas detecting component 11 is described below. The detection principle of different implementation forms:

1. The temperature sensor judges whether the ordinary pressure cooker 2 is exhausted by sensing the change of the temperature of the main pressure cooker 2 or the sudden change of the temperature around the exhaust valve. Before the ordinary pressure cooker 2 starts heating until the exhaust valve is exhausted for the first time, the temperature of the pot body will gradually rise until it reaches a stable temperature, which is approximately 96 ° C, but when the ordinary pressure cooker 2 is exhausted, the pot is The temperature of the body will decrease for a short period of time, approximately 4 ° C to 6 ° C, the temperature drop lasts for about 10 s to 20 s, and then rises rapidly to the stable temperature, so it can be detected by this temperature for a short time. The drop is judged whether or not the ordinary pressure cooker 2 is vented. Similarly, before the exhaust gas of the ordinary pressure cooker 2, the temperature of the exhaust port will continue to be in a stable temperature range. When the ordinary pressure cooker 2 is exhausted, the temperature around the exhaust port will rise for a short time. Then, it quickly drops to the stable temperature range, so it is possible to judge whether or not the ordinary pressure cooker 2 is vented by detecting a change in the temperature of the exhaust port for a short time.

Specifically, the temperature sensitive temperature sensor for detecting the temperature change of the body of the ordinary pressure cooker 2 is mounted on the body of the ordinary pressure cooker 2, such as the lid 22, the pot body 21, or is installed in the middle of the coil pan of the induction cooker 1 and is in close contact with the panel 13 The infrared temperature sensor for detecting the temperature around the exhaust valve is installed at the corner of the induction cooker 1 with the direction facing upward, and can be specifically installed in the bottom cover of the induction cooker 1, and the position of the panel 13 of the induction cooker 1 facing the infrared temperature sensor can be opened. A light hole to facilitate detection of the temperature around the exhaust valve by the infrared temperature sensor. Alternatively, an infrared temperature sensor that detects the temperature around the exhaust valve is mounted on the handle of the ordinary pressure cooker 2.

2. The sound sensor analyzes whether the ordinary pressure cooker 2 is exhausted through the time domain and the frequency domain by sensing the sound of the air jet when the ordinary pressure cooker 2 is exhausted. The sound sensor may be a microphone, and the microphone may be installed around the exhaust valve, for example, on the handle 24 of the ordinary pressure cooker 2, so as to more sensitively sense the sound emitted by the ordinary pressure cooker 2 when exhausted. However, when the microphone is installed around the exhaust valve, it is inconvenient to supply power and transmit data. One solution is to set an independent power supply for the microphone to be supplied to the handle 24 of the ordinary pressure cooker 2, and to set a sound signal to the electronic control board. Wireless data transfer module. The microphone can also be mounted on the induction cooker 1, and in particular, can be mounted on the panel 13 of the induction cooker 1 or on the side wall of the bottom cover. The microphone is mounted on the induction cooker 1 to solve the problem of inconvenient power supply and data transmission to the electronic control board. However, since the sound source from the exhaust gas is relatively far away, there is a problem that the sensitivity of the sound is degraded. In order to solve this problem, one of the solutions is to put between the microphone and the electric control board. The large module and the filtering module extract an effective exhaust signal from the sound signal collected from the microphone.

3. The vibration sensor judges whether the ordinary pressure cooker 2 is exhausted by sensing the vibration signal (such as the vibration caused by the lifting of the weight 23) when the ordinary pressure cooker 2 is exhausted. The vibration sensor may be mounted on the body of the ordinary pressure cooker 2, on the panel 13 of the induction cooker 1 or on the support leg 12 of the bottom cover. Specifically, a microphone or a strain gauge may be used to detect the vibration signal, and the microphone is installed under the panel 13 of the induction cooker 1. And close to the panel 13, the strain gauge is attached to the support leg 12 of the induction cooker 1 to sense the expansion and contraction of the foot pad when the weight 23 of the ordinary pressure cooker 2 rises and falls.

4. The humidity sensor determines whether the ordinary pressure cooker 2 is exhausted by sensing the change in humidity around the exhaust port of the ordinary pressure cooker 2. Specifically, the humidity sensor is detachably mounted on the handle 24 of the ordinary pressure cooker 2 or on the lid 22.

5. The image detecting module judges whether the ordinary pressure cooker 2 is exhausted by sensing the rise and fall of the weight 23 during the exhaust of the ordinary pressure cooker 2 and the image change caused by the air jet. Specifically, it can be realized by a micro-miniature camera or an infrared imaging sensor.

Hereinafter, the technical solution of the present invention will be described in detail by taking an exhaust gas detecting unit 11 using a specific sensor as an example.

Embodiment 1:

As shown in FIG. 3, the exhaust gas detecting component 11 is a sound sensor 111. The sound sensor 111 detects whether the ordinary pressure cooker 2 is exhausted (such as collecting sound through a microphone) by sensing the sound signal during the exhaust process of the ordinary pressure cooker 2. Specifically, The sound sensor 111 transmits the detected sound signal to the electronic control board of the induction cooker 1, and the electronic control board controls the firepower of the induction cooker 1.

2. The generated sound signal is amplified by the primary amplification module 41.

3. The amplified signal enters the filter circuit module 42 for filtering. Since the frequency of the sound signal of the exhaust gas when the ordinary pressure cooker 2 is exhausted is concentrated at 2 kHz to 6 kHz, the filtering module 42 preferably A band pass filter module can be used to output a signal between 2 kHz and 6 kHz; in addition, no filtering process can be performed, that is, the filter module 42 can be omitted in the electronic control board.

4. The signal output by the filtering module 42 is amplified again by the secondary operational amplifier module 43.

5. The signal output by the secondary operational amplifier module 43 is processed by the detection module 44 and the AD sampling module 45 and then acquired by the microprocessor 46.

6. After acquiring the output signal of the AD sampling module 45, the microprocessor 46 performs the mean value, the range difference, and the extreme value calculation on the signal, and determines whether the exhaust gas is exhausted by analyzing the calculated mean value, the range difference, and the extreme value. Specifically, when the frequency of the signal output by the AD sampling module 45 is within a predetermined frequency and the amplitude is within a predetermined amplitude range for a predetermined period of time, it is determined that the ordinary pressure cooker 2 is vented.

7. After determining that the normal pressure cooker 2 is exhausted, the microprocessor 46 counts the exhaust time or the number of exhausts of the ordinary pressure cooker 2 according to the signal output from the AD sampling module 45, and based on the cooking program selected by the user (corresponding to the holding pressure) Time, different cooking programs correspond to different dwell time, that is, corresponding to different target exhaust time or target exhaust times) to control the heating power of the heating control module 47, when the total exhaust time reaches the target exhaust The heating power of the heating control module 47 is reduced when the duration, or the total number of exhausts reaches the target number of exhausts. In the electronic control board structure shown in FIG. 4, the secondary amplification and detection processing may not be performed, that is, the secondary operational amplifier module 43 and the detection module 44 may be omitted.

In addition, the signal connection between the sound sensor 111 and the electronic control board may be wirelessly connected. In this case, the installation position of the sound sensor 111 will not be limited to the position shown in FIG. 3, and may be installed closer to the exhaust. The position of the mouth (such as on the handle 24 of the ordinary pressure cooker 2 or on the lid 22).

Embodiment 2:

As shown in FIG. 5, the exhaust gas detecting component 11 is an acoustic sensor 111 and a temperature sensor 112. The sound sensor 111 and the temperature sensor 112 detect by detecting the sound during the exhaust process of the ordinary pressure cooker 2 (such as collecting sound through a microphone) and temperature change. The exhaust gas is transmitted to the electric control board of the induction cooker 1 and the electric control board is used to control the firepower of the induction cooker 1. Among them, 14 shown in FIG. 5 is an induction cooker base.

Wherein, the temperature sensor 112 may be mounted on the body of the ordinary pressure cooker 2, or installed in the middle of the coil pan of the induction cooker 1 and in close contact with the surface of the panel 13 (ie, the mounting side shown in FIG. 5) In addition, the temperature signal around the exhaust valve can also be detected by an infrared temperature sensor, and the infrared temperature sensor can be specifically mounted in the induction bottom cover 14.

In this embodiment, the internal structure of the electronic control board is as shown in FIG. 6, and includes: a first AD sampling module 61, a primary amplification module 63, a filtering module 64, a secondary amplification module 65, a second AD sampling module 66, and a micro processing. The controller 67 heats the control module 68. Among them, the temperature detecting module 60 shown in FIG. 6 is the temperature sensor 112 in the present invention, and the microphone 62 shown in FIG. 6 is the sound sensor 111 in the present invention. Specifically, the working principle of the sound sensor 111, the temperature sensor 112, and the electronic control board is as follows:

1. The temperature detecting module 60 senses the temperature signal generated by the ordinary pressure cooker 2.

2. The first AD sampling module 61 samples the temperature signal line sensed by the temperature detecting module 60 to convert the analog signal into a digital signal.

3. The signal sampled by the first AD sampling module 61 is input to the microprocessor 67 for determination. Specifically, when the amplitude of the signal output by the first AD sampling module 61 is within a predetermined amplitude range and continues for a predetermined period of time. It is determined that the ordinary pressure cooker 2 is vented.

4. The microphone 62 senses a sound signal generated by the ordinary pressure cooker 2 during exhaust.

5. The sound signal is amplified by the primary amplification module 63.

6. The amplified signal enters the filter circuit module 61 for filtering. The filtering module 64 is preferably a band pass filtering module. The signal amplified by the primary amplification module 63 is filtered by the filtering module 64 to filter out signals outside the frequency of the exhaust signal and output signals between 2 kHz and 6 kHz.

7. The filtered signal is amplified again by the secondary amplification module 65.

8. The signal is sampled and input to the microprocessor 67 via the second AD sampling module 66.

9. The microprocessor 67 determines whether to exhaust by the sampling signal of the second AD sampling module 66. The determining method is: performing mean, range, and extreme value calculation on the signal, and calculating the mean, range, and extreme values obtained through analysis and calculation. Change to determine if the exhaust is exhausted. Specifically, when the frequency of the signal output by the second AD sampling module 66 is within a predetermined frequency and the amplitude is within a predetermined amplitude range for a predetermined period of time, it is determined that the ordinary pressure cooker is vented.

10.

Embodiment 5:

In this embodiment, the exhaust gas detecting component 11 is a temperature sensor 112. The temperature sensor 112 detects the exhaust gas by sensing the temperature change during the exhaust process of the common pressure cooker 2, and transmits the exhaust gas signal to the electronic control board of the induction cooker 1. The electric control board controls the firepower of the induction cooker 1. The temperature sensor 112 can be an infrared temperature sensor or a thermal temperature sensor.

As shown in FIG. 11, the infrared temperature sensor 1121 is placed in the induction cooker bottom cover 14 and is disposed outside the projection range of the ordinary pressure cooker 2 on the induction cooker to detect an area change of the exhaust gas temperature; the infrared ray filter 3 is embedded in The panel 13 is directly above the infrared temperature sensor 1121, and functions to transmit infrared rays corresponding to the steam band and filter out other light; the induction cooker 1 analyzes the temperature change signal detected by the infrared temperature sensor 1121 and changes through the same. The amount is used to judge whether the ordinary pressure cooker 2 is exhausted.

Specifically, according to Planck's law of blackbody radiation, all objects with temperatures above absolute zero are constantly emitting infrared radiation energy to the surrounding space. The magnitude and wavelength distribution of the infrared radiation energy of the object is very close to its surface temperature. The relationship between the surface of the object can be judged by detecting the wavelength of the infrared light emitted by the object. According to this principle, when the ordinary pressure cooker 2 is exhausted, a large amount of high-temperature steam is sprayed around the ordinary pressure cooker 2, causing a change in the temperature field of the surrounding air, which in turn causes a change in the surrounding infrared rays, and infrared rays from the high-temperature steam radiation are detected by the infrared temperature sensor 1121. It is possible to identify whether the ordinary pressure cooker 2 is vented.

After determining that the ordinary pressure cooker 2 is vented, the electric control panel counts the exhaust time or the number of exhausts of the ordinary pressure cooker 2, and based on the cooking program selected by the user (corresponding to the dwell time, different cooking programs correspond to different holding pressures) The time, that is, the different target exhaust time or the number of target exhausts, is used to control the heating power of the induction cooker 1 when the total exhaust time reaches the target exhaust time, or when the total number of exhausts reaches the target exhaust number, The heating power of the induction cooker 1 is lowered.

In addition, in another arrangement in this embodiment, a temperature sensor (preferably an infrared temperature sensor) for detecting the exhaust gas temperature of the common pressure cooker 2 may be disposed on the ordinary pressure cooker 2 with the exhaust port of the ordinary pressure cooker as Within the predetermined area of the center. Specifically, as shown in FIG. 12, the temperature sensor 112 can be disposed on the handle 24 of the ordinary pressure cooker 2, and is oriented toward the ordinary pressure. The exhaust port of the pressure cooker 2. At the same time, the temperature sensor 112 can be connected to the induction cooker 1 by way of wireless connection, so that the induction cooker 1 adjusts the heating power of the induction cooker according to the change of the exhaust gas temperature detected by the temperature sensor 112.

As shown in FIG. 13, the temperature sensitive temperature sensor 1122 can be a layer of temperature measuring film installed next to the panel 13, and the temperature value collected by the induction cooker 1 through the temperature sensor 1122 analyzes the trend of the temperature change to determine the ordinary pressure cooker. 2 Is it exhausted? The thermal temperature sensor 1122 can also be mounted in the middle of the coil disk and attached to the lower surface of the panel 13 to be connected to the electronic control board by wire. In addition, the thermal temperature sensor 1122 can be made into a wireless transmission mode, attached to any position of the pot body, and connected to the induction cooker 1 by wireless means.

Specifically, according to the ideal gas state equation, the temperature of the gas is proportional to the pressure while the other conditions remain unchanged. During the exhaust of the ordinary pressure cooker 2, the pressure of the gas in the pot is rapidly lowered, and the temperature of the gas is also The lowering of the temperature of the pot body is correspondingly reduced. Before and after the ordinary pressure cooker 2 is exhausted, the temperature of the pot body is in a relatively stable state. When the ordinary pressure cooker 2 starts to exhaust, the temperature of the pot body will decrease, and the process lasts for about 10s, then the temperature starts to rise again, and the temperature The falling amplitude is generally 4-6 ° C, by identifying the trend of the temperature drop first and then rising, combined with whether the downward trend is about 10s and whether the falling amplitude is 4-6 ° C to determine whether the ordinary pressure cooker 2 is exhausted. .

Example 6:

In this embodiment, the exhaust gas detecting component 11 is a vibration sensor 113 that detects the exhaust gas by sensing the vibration change in the exhaust process of the ordinary pressure cooker 2, and transmits the exhaust gas signal to the electronic control board of the induction cooker 1, The electric control board controls the firepower of the induction cooker 1.

As shown in FIG. 14, the vibration sensor 113 is mounted next to the panel 13 of the induction cooker 1, and the signal detected by the vibration sensor 113 is amplified and input to the electronic control board of the induction cooker 1, and the electronic control board determines whether the vibration signal is read by the vibration signal. There is a vibration signal. The vibration sensor 113 can also be disposed on the support leg 12. Preferably, the vibration sensor 113 may be a strain gauge or a microphone wind. The strain gauge is mounted at the end of the support leg 12, and the microphone is mounted on the panel 13 or on the side wall of the bottom cover 14. Since the vibration on the induction cooker 1 is transmitted through the ordinary pressure cooker 2, the detection sensitivity of the vibration sensor 113 mounted on the induction cooker 1 is slightly inferior, and an amplification module and a filter module need to be disposed between the electric control board and the vibration sensor 113. To extract an effective vibration signal. The vibration sensor 113 is mounted on the induction cooker 1, facilitating the vibration sensor 113 to transmit data to the electronic control board by wire, and to obtain power from the electronic control board by wire.

As shown in FIG. 15, the vibration sensor 113 can also be movably disposed on the ordinary pressure cooker 2. This type of installation can more sensitively sense the vibration signal emitted by the ordinary pressure cooker 2 during vibration, but there is a problem that power supply and transmission of data are inconvenient. Therefore, it is preferable that the vibration sensor 113 can be made into a wireless transmission mode, that is, wirelessly connected to the induction cooker 1. At the same time, the vibration sensor 113 is provided with an independent power supply.

Example 7:

In this embodiment, the exhaust gas detecting component 11 is a humidity sensor 114 that detects the exhaust gas by sensing the change in the air humidity of the exhaust port during the exhaust process of the ordinary pressure cooker 2, and transmits the exhaust gas signal to the induction cooker 1 The electric control board and the electric control board control the firepower of the induction cooker 1.

As shown in FIG. 16, the humidity sensor 114 is for detecting an air humidity signal around the exhaust port of the ordinary pressure cooker 2 to sense the humidity change when the ordinary pressure cooker 2 is exhausted. The humidity sensor 114 can be disposed near the exhaust port of the common pressure cooker 2. As shown in FIG. 16, the humidity sensor 114 can be detachably disposed on the handle 24 of the ordinary pressure cooker 2 and facing the exhaust port of the ordinary pressure cooker 2. Preferably, the humidity sensor 114 can be connected to the induction cooker 1 by means of a wireless connection, so that the induction cooker 1 adjusts the heating power to the ordinary pressure cooker according to the change of the exhaust gas signal detected by the humidity sensor 114. Further, the humidity sensor 114 may be disposed on the lid 22 of the ordinary pressure cooker.

In other embodiments of the invention, the heating device may also be a gas stove or an electric baking pan.

The technical solution of the above embodiment enables the heating device (such as the induction cooker) to automatically judge whether the cooking appliance (such as a common pressure cooker) is in an exhaust state, and can count the exhaust time or the number of exhausts of the cooking appliance, and based on the cooking selected by the user. The program (corresponding to the dwell time, different cooking programs correspond to different dwell time, that is, corresponding to different target exhaust time or target exhaust times), the heating power is controlled, and when the total exhaust time reaches the target row Gas length, or row When the total number of gas reaches the target number of exhausts, the heating power to the cooking appliance is lowered, and automatic control of the cooking appliance is realized. It can be seen that the technical solution of the present invention can let the user get rid of the heavy cooking chores, and no longer need to pay attention to the working condition of the cooking utensils at the same time, and can avoid the safety hazard caused by the negligence of the user.

Figure 17 shows a schematic flow diagram of a cooking method of a heating apparatus in accordance with an embodiment of the present invention, in which the heating apparatus includes a heating assembly, an exhaust gas detecting assembly, and an electrical control board.

As shown in FIG. 17, a cooking method of a heating apparatus according to an embodiment of the present invention includes:

Step S170, the exhaust gas detecting component detects an exhaust signal of the cooking appliance during heating of the cooking appliance by the heating component.

Step S172, the electronic control board counts the exhaust time or the number of exhausts of the cooking appliance according to the exhaust signal detected by the exhaust gas detecting component.

Step S174, the electronic control panel adjusts the heating parameter of the heating component according to a cooking program selected by the user to control the total exhaust time or the total number of exhaust gases of the cooking appliance. Wherein, the heating parameters include: heating power.

Since different cooking procedures have different dwell times, for example, the dwell time corresponding to the cooking process and the soup process is different, and the dwell time is positively related to the number of exhausts of the cooking appliance or the exhaust time, that is, cooking. The greater the number of exhausts of the appliance or the longer the length of the exhaust, the longer the pressure holding time. Therefore, in an embodiment of the present invention, the step S174 specifically includes: the duration of the holding of the electronic control panel according to the cooking program selected by the user. Determining a target exhaust duration or a target number of exhausts of the cooking appliance; adjusting a heating parameter of the heating assembly according to the target exhaust duration or the number of target exhausts.

The step of adjusting the heating parameter of the heating component according to the target exhaust time duration or the target exhaust time, specifically includes: the total exhaust time of the electronic control panel in the cooking appliance reaches the target exhaust time duration Or reducing the heating power of the heating assembly after the total number of exhausts of the cooking appliance reaches the target number of exhausts.

In the cooking method of the heating device shown in FIG. 17, since the different holding materials have different holding pressures during the cooking process, and there is a correlation between the dwell time and the exhaust time and the number of exhausts of the cooking utensils, The control panel adjusts the heating parameter of the heating component according to a cooking program selected by the user (the different cooking program corresponds to different holding time), so that the heating device can automatically adjust the heating parameter of the heating component according to the cooking program selected by the user, For cooking The pressure holding time of the process is controlled, thereby realizing the function of automatic cooking, and solving the problem that the user needs to pay attention to the working condition of the cooking appliance at all times when using the cooking utensils, especially the non-smart cooking utensils (such as ordinary pressure cooker), not only saving The user's cooking time, and can help the user (especially the user with insufficient cooking experience) to cook, greatly improving the user experience.

The following application scenarios of the above solution of the present invention are listed:

Application scenario 1:

In this scenario, cooking control can be achieved by counting the number of exhausts. This method is especially suitable for cooking programs that require a shorter dwell time, such as cooking, and the following is a detailed description of cooking:

The user selects the fast cooking function and selects the cooking taste (including a hard, moderate, soft mouthfeel). Among them, in a normal pressure cooker, the soft mouth feel preferably corresponds to 1-2 times of exhaust, the hard taste is preferably 6-7 times, and the moderate mouth feel preferably corresponds to 3-5 times of exhaust.

Take the user's choice of moderate taste (in this case, the moderate mouthfeel corresponds to 3 times of exhaust) as an example to describe the cooking process: When the user starts the cooking function and selects a moderate taste, the induction cooker heats the pressure cooker, and the initial heating power is 1200W. When the pressure in the pressure cooker increases to a certain extent, the pressure cooker begins to vent. When the pressure cooker is detected, the induction cooker compares the detected number of exhausts with the set number of exhausts corresponding to the set mouth (three times in this example). When the two are equal, the induction cooker automatically reduces the heating power, as in this example. Reduce the power to 500W, enter the insulation stage, and remind the user to complete the cooking by ringing. At the same time, because the pressure cooker does not have enough heating power, the pressure in the pot will gradually decrease, the exhaust will be terminated, but the temperature will be maintained at a certain temperature.

Application scenario 2:

In this scenario, cooking control can be achieved by counting the exhaust time. This method is especially suitable for soups, stews and other cooking processes with long holding time. For example, pork ribs, beef, chicken and other ingredients are usually pressed in the pressure cooker, and pressure is required for 10-15 minutes. For details, please explain:

When the user activates the stew ribs function, the induction cooker heats the pressure cooker, and the heating power is preferably 1200 W. When the pressure in the pressure cooker increases to a certain extent, the pressure cooker starts to vent. When the pressure cooker is detected for 1 time, the cooking program immediately enters the pressure holding stage, the induction cooker automatically adjusts the heating power to 1000W, and starts the dwell time, and the pressure cooker continues at 1000W heating power. During the exhaust-pressure-holding process, when the statistical dwell time reaches the dwell time set by the stewed pork ribs (in this example, 10 minutes), the induction cooker automatically stops heating the pressure cooker and reminds the user to complete the cooking by ringing. Of course, you can also enter the insulation phase.

It should be noted that the specific values in the application scenario 1 and the application scenario 2 are only examples, and are not specifically limited. In other embodiments of the present invention, adjustments may be made according to actual conditions.

At the same time, during the heating process of the cooking appliance, the heating device can adjust the heating firepower by counting the number of exhausting of the cooking appliance, or can adjust the heating firepower by counting the exhausting time of the cooking appliance. That is to say, in the above application scenario 1, the heating control is not limited to the counting of the number of exhausts, and the heating control may be performed by counting the exhaust time; in the second application scenario, the heating control is not limited to the statistical exhaust time. Heating control can be performed by counting the number of exhausts.

Although the present invention has been described in detail by way of illustration and example embodiments of the present invention, it will be understood that Some variations and modifications of the invention are possible. It is understood that the terminology used herein is for the purpose of illustration and description,

The above description is only the preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes can be made to the present invention.
