[0035] The present invention is further described in detail below with reference to the accompanying drawings.

[0036] like Figures 1 to 3 As shown, the cooking device in this embodiment includes a heating plate 1, a container 2, a support column 3, a pressure detector 4, a first drive mechanism 5, and a control circuit board 100. The control circuit board 100 is electrically signal-connected to the heating plate 1, the pressure detector 4, and the first drive mechanism 5, respectively. The control circuit board 100 can obtain detection data of the pressure detector 4, and can also control the heating plate 1 and the first drive mechanism 5 to work.

[0037] The heating plate 1 in this embodiment can adopt various heating plates 1 used in cooking devices in the prior art. In order to ensure uniform heating, the bottom surface of the container 2 is usually flat, and the bottom surface and the peripheral wall of the container 2 have an arc transition. In order to facilitate matching the shape of the container 2, improve the heating effect of the container 2, and increase the heating area, the structure of the heating plate 1 is set as follows: it has a flat bottom surface, and the heating plate 1 is curved upward in the circumference to form a side wall with an arc cross section. The side wall can match the bottom of the container 2. On the one hand, it can improve the convenience of operation when the container 2 is placed on the heating plate 1, which is conducive to quickly placing the container 2 in place and reducing the situation where the container 2 is placed on the heating plate 1. On the other hand, the heating area is increased, and the heating of the container 2 is more uniform.

[0038] The container 2 can be detachably arranged on the heating plate 1 , and the shape of the container 2 can be specifically configured according to needs, for example, the container 2 can be a plate, a pot, etc.

[0039] The support columns 3 include at least three groups and are circumferentially arranged below the heating plate 1. As needed, each group of support columns 3 may include one support column 3, or may include two or more support columns 3. The upper ends of the support columns 3 in each group pass through the heating plate 1 and protrude above the heating plate 1. In order to prevent the container 2 from separating from the heating plate 1, in the initial state or normal cooking state, the distance between the top of the support column 3 and the heating plate 1 is very limited, that is, the top of the support column 3 is slightly higher than the inner bottom surface of the heating plate 1, so as to be able to contact the bottom of the container 2 so as to realize the weight detection of the container 2, while not affecting the heating of the container 2 by the heating plate 1.

[0040] The pressure detector 4 is arranged at the top of each group of support columns 3, and the weight of the container 2 placed at different positions on the heating plate 1 is detected by the pressure detector 4. The pressure detector 4 can adopt various sensors capable of realizing pressure detection in the prior art. For the sake of simplicity of structure, a patch-type pressure detector 4 can be adopted. The pressure detector 4 in this embodiment adopts a piezoelectric ceramic sheet.

[0041] One first driving mechanism 5 is provided for each support group, and the first driving mechanism 5 is connected to the support column 3 to drive the support column 3 to vibrate up and down. By driving the support column 3 to vibrate up and down, the container 2 placed in the heating plate 1 can be driven to vibrate up and down, which is beneficial to adjust the position of the container 2 on the heating plate 1 and to adjust the distribution uniformity of the food in the pot in the container 2. Figure 4 As shown, in order to further improve the adjustment of the position of the container 2 on the heating plate 1 and the uniformity of the distribution of food therein, the first driving mechanism 5 in this embodiment can also drive the first support column 3 to swing horizontally along the plate body, and in order to match the swinging action, a waist-shaped hole 11 is opened on the heating plate 1 corresponding to the position where each group of support columns 3 are inserted, and the first driving mechanism 5 is connected to the support column 3 in a transmission manner and can drive the support column 3 to swing in the waist-shaped hole 11. The first driving mechanism 5 can adopt various driving structures that can achieve up and down, left and right swings in the prior art. In this way, based on the up and down driving and horizontal swing driving of the support column 3 by the first driving mechanism 5, the up and down vibration and horizontal swing driving of the container 2 on the heating plate 1 are correspondingly achieved, thereby better adjusting the posture of the container 2 on the heating plate 1, so that the container 2 is placed on the heating plate 1, which is conducive to the uniformity of heating each area of ​​the container 2 by the heating plate 1 during cooking. At the same time, during the vibration and swinging process of the container 2, the uniform distribution of food in the container 2 can also be better adjusted to avoid the accumulation of food in a local position, improve the uniformity of heating the food in the container 2 during cooking, and thus improve the cooking effect.

[0042] In order to further confirm the placement of the container 2 on the heating plate 1 and to realize intelligent control based on the signal of the micro switch 6, a micro switch 6 is also included below the heating plate 1. A support rod 7 is provided above the micro switch 6. The upper end of the support rod 7 passes through the heating plate 1 and protrudes above the heating plate 1. The micro switch 6 is electrically connected to the control circuit board 100. In order to ensure that the placement of the container 2 on the heating plate 1 can be detected, the support rod 7 in this embodiment is passed through the center of the heating plate 1. In order to ensure that the support rod 7 can automatically reset to the position of disconnecting the micro switch 6 and avoid the misjudgment of the micro switch 6 caused by the support rod 7, the support rod 7 in this embodiment is arranged based on an elastic member, and the elastic member has a tendency to press the support rod 7 upward so that the upper end of the support rod 7 protrudes above the heating plate 1. During use, when the container 2 is placed on the heating plate 1, the container 2 will press down the support rod 7, and then the support rod 7 will trigger the micro switch 6, making the micro switch 6 turned on, and then based on the conduction signal of the micro switch 6, it can be judged that the container 2 has been placed on the heating plate 1, and then the control circuit board 100 can perform some intelligent control based on the signal control of the micro switch 6.

[0043] The aforementioned cooking device can be applied to electric appliances such as rice cookers that require users to operate the cover body. The cooking device in this embodiment also includes a box 8, a drawer 9 that opens and closes relative to the box 8, and a heating plate 1 and a first driving mechanism 5 are arranged on a drawer board 91 of the drawer 9. That is, the cooking device is a drawer 9 type cooking device. In order to facilitate the pulling of the drawer 9, slide rails 81 are arranged on both sides of the box 8, and a positioning member 92 limited in the slide rail 81 is arranged at the bottom of the drawer 9. In order to facilitate the automatic drive of the drawer 9, a second driving mechanism 200 that drives the drawer 9 to move relative to the slide rail 81 is also arranged in the box 8. The second driving mechanism 200 is connected to the control circuit board 100 by electrical signals. The second driving mechanism 200 can adopt a driving mechanism that can realize automatic drive in products such as dishwashers and disinfection cabinets in the prior art, so as to facilitate the automatic drive of the drawer 9 to open and close. In this embodiment, the control circuit board 100 can control the second driving mechanism 200 to work based on the conduction signal of the micro switch 6, and then the second driving mechanism 200 drives the drawer 9 to close. That is, after the user places the container 2 on the heating plate 1, the micro switch 6 will be turned on based on the downward pressure of the support rod 7. The control circuit board 100 starts timing after obtaining the conduction signal of the micro switch 6. When the timing reaches the set time, it is determined that the user no longer needs to operate the container 2. At this time, the second drive mechanism 200 is controlled to drive the drawer 9 to close.

[0044] The cooking method of the aforementioned cooking device is as follows: each pressure detector 4 detects and obtains pressure data. Since the pressure detectors 4 are arranged at different positions around the heating plate 1, the pressure data of different positions can be obtained. When the container 2 is not placed on the heating plate 1, the pressure detector 4 is not subjected to pressure, and the corresponding pressure data detected by each pressure detector 4 is 0. When the container 2 is placed on the heating plate 1, at least one pressure detector 4 will be pressed, and the pressure data of the pressure detector 4 pressed by the container 2 will change, and the pressure detector 4 will detect a pressure value greater than 0. Therefore, in this embodiment, the placement of the container 2 on the heating plate 1 is judged based on the pressure data detected by each pressure detector 4.

[0045] Specifically, the method for judging the placement of the container 2 on the heating plate 1 is: if at least one of the pressure data obtained by each pressure detection data is greater than 0, it is judged that the container 2 is placed on the heating plate 1; otherwise, it is judged that the container 2 is not placed on the heating plate 1, and based on other detection information of the cooking device, such as detecting that the drawer 9 of the cooking device is in an open state, the control circuit board 100 can control the reminder to place the container 2 on the heating plate 1.

[0046] When determining whether the container 2 is placed on the heating plate 1, it is determined based on the pressure data whether there is an abnormality in the container 2 on the heating plate 1. The abnormality in this embodiment includes that the container 2 is not placed properly on the heating plate 1, food is partially accumulated in the container 2, and there is dirt and foreign matter at the bottom of the container 2.

[0047] In order to facilitate the judgment of the abnormal situation of the container 2, the method for judging whether there is an abnormal situation of the container 2 on the heating plate 1 in the present embodiment is: calculate and obtain the absolute value of the difference between every two data, if at least one absolute value of the difference is greater than the set absolute value threshold of the difference, it is judged that there is at least one abnormal situation of the container 2 on the heating plate 1.

[0048] The two situations of improper placement on the heating plate 1 and partial accumulation of food in the container 2 can usually be solved by adjusting the posture of the container 2 on the heating plate 1, vibrating or shaking the container 2. However, when there is dirt on the bottom of the container 2, it cannot be effectively solved even if the container 2 is vibrated or shaken to change the posture of the container 2. Based on this, in this embodiment, when judging whether the container 2 is abnormal on the heating plate 1, the corresponding method is as follows.

[0049] When it is determined that there is an abnormality in the container 2 on the heating plate 1, the container 2 is controlled to be driven to vibrate for a set time.

[0050] After the container 2 stops vibrating, each pressure detector 4 re-detects and obtains pressure data, and determines whether there is an abnormality in the container 2 on the heating plate 1 based on the pressure data. If it is determined that the container 2 is still abnormal on the heating plate 1, it is determined that there is dirt and foreign matter at the bottom of the container 2. At this time, in order to remind the user to clean the dirt and foreign matter to avoid affecting cooking, when it is determined that there is dirt and foreign matter at the bottom of the container 2, the control reminds the user to clean the container 2.

[0051] The cooking device and cooking method of the present invention can use the pressure data of different positions of the container 2 placed on the heating plate 1 by each pressure detector 4, and then judge the abnormal conditions such as the container 2 being placed skewed, the food in the container 2 being stacked skewedly, or the presence of dirt and foreign matter on the container 2 according to the pressure data, and can use the first driving mechanism 5 to drive the container 2 through the support column 3 to adjust the posture of the container 2, adjust the uneven distribution of food in the container 2, and can also detect and prompt the dirt on the bottom of the pot. Therefore, the uniformity of heating the food in the container 2 can be improved, and the cooking effect can be improved.

[0052] This embodiment also involves a computer-readable storage medium, which stores computer instructions, and the computer instructions are used to enable a computer to execute the aforementioned cooking method.
