Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.
Fig. 1 shows a schematic flow diagram of a cooking method of a heating device according to an embodiment of the invention.
The heating device comprises a heating assembly, an exhaust detection assembly and an electric control plate. As shown in fig. 1, a cooking method of a heating apparatus according to an embodiment of the present invention includes:
102, detecting an exhaust signal of a cooking appliance by an exhaust detection assembly in the process of heating the cooking appliance by a heating assembly;
and 104, adjusting the heating power of the heating assembly by the electric control board according to the exhaust signal detected by the exhaust detection assembly.
Wherein the cooking appliance can be a common pressure cooker. Pressure cookers are generally classified into two types, one is a common pressure cooker, and the other is an electric pressure cooker. Generally, a common pressure cooker and heating equipment are separated, and the heating equipment can be a gas stove, an induction cooker, an electric heating plate or the like; the electric pressure cooker is integrated with a heating component, and the heating component is generally an electric heating plate or an IH coil plate. One of the cooking appliances provided in this embodiment is a general pressure cooker. As shown in fig. 2, the conventional pressure cooker includes a cooker body 21, a cooker cover 22 for covering the cooker body 21, a handle 24 for holding is disposed at one end of the cooker body 21 and the cooker cover 22 along a radial direction, an exhaust valve and a float valve are disposed on the cooker cover 22, the float valve exhausts cold air at an initial stage of the pressure cooker, a weight 23 is covered on the exhaust valve (the exhaust valve in fig. 2 is covered by the weight 23), the exhaust valve is provided with an axial exhaust port, when the air pressure in the conventional pressure cooker is greater than the gravity of the weight 23, the weight 23 is lifted vertically, the pressure cooker starts to exhaust air, after a period of exhaust, the air pressure in the conventional pressure cooker is lower than the pressure of the weight 23, the weight 23 falls back, and the pressure cooker stops to exhaust air, thereby completing one. After a certain period of heating, the pressure in the ordinary pressure cooker is again higher than the gravity of the weight 23, and a new round of exhausting is started. In this embodiment, the exhaust signal generated when the weight 23 rises and falls in the common pressure cooker is detected by the sensor, and whether the exhaust valve is in the exhaust state is further determined.
It should be noted that, in the prior art, some exhaust valves of a common pressure cooker are provided with a plurality of radial exhaust ports, so that once the pressure in the cooker is greater than a preset value, the exhaust is stopped, and the weight is driven to rotate around the exhaust valve until the food is cooked. This part of the conventional pressure cooker is different from the conventional pressure cooker provided in the present embodiment. Of course, the cooking appliance may also be a hot water kettle.
Because cooking utensil's exhaust signal can show cooking utensil's operating condition to a certain extent, if whether be in boiling state in the cooking utensil, cooking utensil's exhaust number of times also can show the culinary art condition of food in the cooking utensil simultaneously, consequently through setting up exhaust detection component and detecting cooking utensil's exhaust signal, and adjust heating element's heating power through automatically controlled board according to the exhaust signal that exhaust detection component detected, when using cooking utensil, especially non-intelligent cooking utensil, need the user to pay close attention to cooking utensil operating condition's problem constantly, user's time has been saved, be favorable to promoting user's use experience.
The cooking method of the heating device according to the above embodiment of the present invention may further have the following technical features:
according to an embodiment of the present invention, the step of adjusting the heating power of the heating assembly by the electronic control board according to the exhaust signal detected by the exhaust detection assembly specifically includes: the electric control board judges whether the cooking appliance exhausts according to the exhaust signal detected by the exhaust detection assembly, counts the times of exhausting of the cooking appliance after judging that the cooking appliance exhausts, and adjusts the heating power of the heating assembly according to the times of exhausting completed by the cooking appliance.
Because the exhaust frequency of the cooking appliance can represent the cooking condition of food in the cooking appliance, the exhaust frequency of the cooking appliance is counted, and the heating power of the heating assembly is adjusted according to the exhaust frequency completed by the cooking appliance, so that the heating equipment can automatically adjust the heating power of the heating assembly according to the cooking condition of the food in the cooking appliance, the program needing user participation in the cooking process is reduced, and the cooking time of the user is saved.
According to one embodiment of the invention, the exhaust detection assembly includes an exhaust pre-detection sensor and an exhaust verification sensor; the step that the electric control board judges whether the cooking utensil exhausts or not according to the exhaust signal detected by the exhaust detection assembly specifically comprises the following steps: the electric control board pre-judges whether the cooking appliance exhausts according to the exhaust signal detected by the exhaust pre-detection sensor, and determines whether the cooking appliance exhausts according to the exhaust signal detected by the exhaust verification sensor after pre-judging that the cooking appliance exhausts.
Whether the cooking utensil exhausts is detected through setting up exhaust preliminary examination sensor and exhaust verification sensor jointly, promptly when exhaust preliminary examination sensor judges the exhaust that the cooking utensil takes place again according to the exhaust signal that exhaust verification sensor detected and confirms that the cooking utensil takes place to exhaust after the exhaust takes place, just final definite cooking utensil is in the exhaust state, has improved the accuracy that detects cooking utensil exhaust state.
According to one embodiment of the present invention, the exhaust signal detected by the exhaust gas pre-detection sensor is a sound signal, and the exhaust signal detected by the exhaust gas verification sensor is a vibration signal, a temperature signal, or a combination of the vibration signal and the temperature signal.
In this embodiment, the exhaust gas preliminary detection sensor corresponding to the sound signal is a sound sensor, the exhaust gas verification sensor corresponding to the vibration signal is a vibration sensor, and the exhaust gas verification sensor corresponding to the temperature signal is a temperature sensor.
According to an embodiment of the present invention, the step of adjusting the heating power of the heating assembly according to the number of exhaust times completed by the cooking appliance specifically includes: the electric control board reduces the heating power of the heating assembly after the cooking appliance finishes the preset exhaust times.
In this embodiment, the adjustment of the heating power of the heating assembly is in particular to keep the previous heating power for heating when the cooking appliance has not completed the predetermined number of exhausts; the heating power of the heating assembly is reduced after the predetermined number of exhausts has been completed. Specifically, taking the heating device as an induction cooker and the cooking utensil as a common pressure cooker as an example, when the common pressure cooker generates the 1 st exhaust and the 2 nd exhaust, the induction cooker can heat at full power, and after the common pressure cooker generates the 3 rd exhaust, the induction cooker adjusts the heating power to another heating power lower than the full power to heat.
In another embodiment of the present invention, the heating power of the heating assembly may also be adjusted each time the occurrence of the exhaust of the cooking appliance is detected. Specifically, taking an electromagnetic oven as heating equipment and a common pressure cooker as cooking appliances as examples, before the common pressure cooker exhausts for the 1 st time, the electromagnetic oven heats at full power; when detecting that the 1 st exhaust of the common pressure cooker occurs, heating the induction cooker at a first power lower than full power; when the 2 nd exhaust of the ordinary pressure cooker is detected, the induction cooker heats at the second power lower than the first power, and when the 3 rd exhaust of the ordinary pressure cooker is detected, the induction cooker heats at the third power lower than the second power so as to achieve the effect of stewing soup with soft fire.
Generally, the other power in the first adjustment mode and the third power in the second adjustment mode are zero or the heat preservation power with extremely low power, which basically corresponds to stopping heating, namely, when the common pressure cooker finishes the third exhaust, the cooked food is considered to be cooked. In other words, in the present embodiment, the electric control board determines whether the food is cooked by whether the ordinary pressure cooker completes the predetermined number of times of exhausting. The preset exhaust frequency in the embodiment is specifically 3, and when the exhaust frequency of the ordinary pressure cooker reaches 3 times, the food in the ordinary pressure cooker is judged to be cooked. Of course, the preset exhaust times of the common pressure cooker can be adjusted correspondingly according to different types and quantities of food. For example, the predetermined number of times of exhaustion may be adjusted to 1 or 2 for food which is small in quantity and easy to cook, that is, the heating power of the induction cooker may be adjusted to zero when the ordinary pressure cooker exhausts 1 or 2 times, and the predetermined number of times of exhaustion may be adjusted to 4, 5 or more for food which is large in quantity and difficult to cook.
The invention also proposes a heating device comprising: the heating assembly is positioned below a cooking appliance and used for heating the cooking appliance; an exhaust detection assembly for detecting an exhaust signal of the cooking appliance; and the electric control board is connected to the heating assembly and the exhaust detection assembly and is used for adjusting the heating power of the heating assembly according to the exhaust signal detected by the exhaust detection assembly.
Wherein, the heating device can be an electromagnetic oven, a gas stove or an electric heating plate; the cooking appliance may be a conventional pressure cooker or a kettle.
The technical solution of the present invention will be described in detail below with reference to fig. 2 to 10, taking an example in which the heating device is an induction cooker and the cooking appliance is a common pressure cooker.
As shown in fig. 2, the induction cooker 1 has an exhaust gas detecting unit 11 and an electric control board, and a coil panel (not shown in the figure) for heating the general pressure cooker 2, a front panel 13 for supporting the general pressure cooker 2, and a bottom cover for accommodating the coil panel and the electric control board. The conventional pressure cooker 2 includes a cooker body 21, a cooker cover 22 for covering the cooker body 21, an exhaust valve (the exhaust valve in fig. 2 is covered by a weight 23) disposed on the cooker cover 22, and a weight 23 sleeved on the exhaust valve.
Wherein, the exhaust gas detection subassembly 11 includes the combination of one or more in the temperature sensor, the sound sensor, vibration sensor, humidity transducer, the image detection module, whether exhaust of ordinary pressure cooker 2 is detected through the change of temperature signal, sound signal, vibration signal, humidity signal, image signal etc. of the ordinary pressure cooker 2 exhaust process of perception to exhaust gas detection subassembly 11 to transmit the exhaust gas signal to the automatically controlled board of electromagnetism stove 1, the automatically controlled board controls the firepower size of electromagnetism stove 1, the following different detection principles that embody the form of exhaust gas detection subassembly 11:
1. the temperature sensor judges whether the ordinary pressure cooker 2 exhausts or not by sensing the change of the temperature of the ordinary pressure cooker 2 body or the sudden change of the temperature around the exhaust valve. The temperature of the pot body of the ordinary pressure cooker is gradually increased until reaching a stable temperature which is approximately near 96 ℃ before the ordinary pressure cooker is heated to the exhaust valve for the first time, but when the ordinary pressure cooker 2 is exhausted, the temperature of the pot body is reduced for a short time which is approximately 4 ℃ to 6 ℃, the duration time of the temperature reduction is approximately 10s to 20s, and then the temperature is rapidly increased to the stable temperature, so that whether the ordinary pressure cooker exhausts can be judged by detecting the temperature for the short time. Similarly, the temperature of the exhaust port of the conventional pressure cooker 2 is kept within a stable temperature range before exhausting, and when the conventional pressure cooker 2 exhausts, the temperature around the exhaust port rises for a short time and then rapidly falls to the stable temperature range, so that whether the conventional pressure cooker 2 exhausts or not can be judged by detecting the change of the temperature of the exhaust port for a short time. Specifically, the heat-sensitive temperature sensor for detecting the temperature change of the body of the ordinary pressure cooker 2 is installed on the body of the ordinary pressure cooker 2, such as a cooker cover and a cooker body, or is installed in the middle of a coil panel of the induction cooker 1 and is attached to the lower surface of the panel 13; an infrared temperature sensor for detecting the ambient temperature of the exhaust valve is installed at a corner of the induction cooker 1, the direction of the infrared temperature sensor is upward, the infrared temperature sensor can be specifically installed in a bottom cover of the induction cooker, a light hole (not shown in the figure) is formed in a position, which faces the infrared temperature sensor, of a panel 13 of the induction cooker 1, and a light filter (such as an infrared light filter) is embedded in the light hole. Alternatively, an infrared temperature sensor for detecting the temperature around the exhaust valve is mounted on the handle of the general pressure cooker 2.
2. The sound sensor analyzes whether the ordinary pressure cooker 2 exhausts or not through time domain and frequency domain by sensing the sound of air injection when the ordinary pressure cooker 2 exhausts. Wherein, the sound sensor can adopt a microphone, and the microphone can be arranged around the exhaust valve, such as on the handle of the common pressure cooker 2, so as to sense the sound emitted when the common pressure cooker 2 exhausts more sensitively. However, the microphone is arranged around the exhaust valve, and the problems of inconvenient power supply and data transmission are met, wherein one solution is to arrange an independent power supply for supplying power to the microphone on the handle of the common pressure cooker 2 and a wireless data transmission module for sending sound signals to the electric control board. The microphone may also be mounted on the induction cooker, in particular, on the panel 13 of the induction cooker 1 or on the side wall of the bottom cover. The microphone is arranged on the induction cooker, so that the problem of inconvenience in power supply and data transmission to the electric control board can be solved, but the problem of reduction of sound perception sensitivity can exist due to the fact that the microphone is far away from an exhaust sound source. In order to solve this problem, one solution is to provide an amplifying module and a filtering module between the microphone and the electronic control board to extract an effective exhaust signal from the sound signal collected by the microphone.
3. The vibration sensor judges whether the ordinary pressure cooker 2 is exhausted by sensing a vibration signal (such as vibration caused by rising and falling of the weight 23) generated when the ordinary pressure cooker 2 is exhausted. The vibration sensor can be installed on the body, the panel 13 or the supporting legs 12 of the bottom cover of the ordinary pressure cooker 2, specifically, a microphone or a strain gauge can be used for detecting a vibration signal, the microphone is installed below the panel 13 of the induction cooker 1 and clings to the panel 13, and the strain gauge is clinged to the supporting legs 12 of the induction cooker 1 to sense the expansion and contraction change of the foot pad when the weight 23 rises and falls.
4. The humidity sensor judges whether the ordinary pressure cooker 2 exhausts or not by sensing the humidity change 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 the lid 22 of the ordinary pressure cooker 2.
5. The image detection module judges whether the common pressure cooker 2 exhausts or not by sensing the rise and fall of the weight 23 and the image change caused by the air injection when the common pressure cooker 2 exhausts. In particular, the method can be realized by a microminiature camera or an infrared imaging sensor.

Specifically, when the frequency of the signal output by the AD sampling module 45 is within a predetermined frequency, the amplitude is within a predetermined amplitude range, and the signal lasts for a predetermined time period, it is determined that the exhaust of the ordinary pressure cooker occurs.
7. The microprocessor 46 compares the detected number of times of exhaust with a preset number of times of exhaust, and when the number of times of exhaust reaches the preset value, the heating control module 47 adjusts the fire.
