[0002] In existing technologies, automated cooking pots communicate with the stove's control module via a wireless module. The stove is equipped with a temperature sensor that contacts the bottom of the pot. The control module identifies the current cooking status based on the pot's bottom temperature detected by the sensor and adaptively adjusts the stove's heating power according to a preset program. For example, if the pot's bottom temperature exceeds a preset threshold, the control module controls the stove to reduce its heating power or turn off the heat. However, after the water boils, the temperature change between the inside and bottom of the pot is small when the water level is low and moderate. The stove cannot accurately adjust its heating power based on the pot's bottom temperature, making it prone to burning. Utility Model Content

[0048] Example 1

[0049] like Figure 1 , Figure 2 and Figure 6 As shown, the pot rack provided by this utility model includes: a support frame 1 and a gravity sensor 2. The support frame 1 includes an annular frame with three or four legs 11. The upper end of each leg 11 is used to support the pot. A gravity sensor 2 is pressed into the lower end of each leg 11, and the gravity sensor 2 supports the support frame 1.

[0050] The pot is placed on the support legs 11 of the support frame 1. The lower end of the gravity sensor 2 is supported on the stove surface. The gravity sensor 2 can detect the weight of the pot. Based on the weight change, the amount of water evaporated during the automatic cooking process can be determined. When the weight of the ingredients and water poured into the pot is known, the approximate amount of water remaining in the pot can be estimated based on the current weight of the pot. A warning is issued before the water level drops below the threshold to avoid the water in the unattended pot boiling dry.

[0051] like Figure 3 and Figure 4As shown, the gravity sensor 2 includes a support block 21 and a stress section 22. The stress section 22 is connected to the support block 21 and is used to detect the deformation of the support block 21. The support block 21 is subjected to pressure deformation, which correspondingly changes the resistance value, electromagnetic force, or capacitance of the stress section 22. The measurement circuit collects the corresponding changes in the stress section 22 and converts these changes into voltage values ​​or other electrical signals to transmit gravity information.

[0052] The support block 21 includes a top support portion 211, a connecting portion 212, and a bottom support portion 213 arranged vertically in sequence. The top support portion 211 includes a first end 2111 and a second end 2112 arranged laterally opposite each other. The bottom support portion 213 includes a third end 2131 and a fourth end 2132 arranged laterally opposite each other. The first end 2111 and the third end 2131 are on the same side, and the second end 2112 and the fourth end 2132 are on the same side. The connecting portion 212 is located between the first end 2111 and the second end 2112, and between the third end 2131 and the fourth end 2132. The first end 2111 and the third end 2131 are arranged vertically at intervals, and the second end 2112 and the fourth end 2132 are arranged vertically at intervals. This makes the support block 21 roughly "I" shaped. The vertical gap between the first end 2111 and the third end 2131 and the vertical gap between the second end 2112 and the fourth end 2132 can provide the support block 21 with a larger deformation. The increased deformation can improve the detection accuracy.

[0053] Furthermore, a first groove 214 recessed towards the side opposite to the bottom support portion 213 is provided between the first end 2111 and the connecting portion 212; a second groove 215 recessed towards the side opposite to the bottom support portion 213 is provided between the second end 2112 and the connecting portion 212; a third groove 216 recessed towards the side opposite to the top support portion 211 is provided between the third end 2131 and the connecting portion 212; and a fourth groove 217 recessed towards the side opposite to the top support portion 211 is provided between the fourth end 2132 and the connecting portion 212. By creating additional grooves (first groove 214, second groove 215, third groove 216, and fourth groove 217) within the original "I"-shaped left and right gaps, the gap width can be further increased, improving accuracy.

[0054] like Figures 5-7 As shown, the pot rack also includes a foot pad 3, which is vertically floatingly connected to the support frame 1. The foot pad 3 has an inner cavity 31, and the gravity sensor 2 is located in the inner cavity 31.

[0055] The foot pad 3 serves to protect the gravity sensor 2. It is connected to the support frame 1 in a floating manner to avoid the foot pad 3 affecting the weighing. After the pot is placed on the support frame 1, the pressure of the support leg 11 is all on the weighing sensor. The foot pad 3 will not obstruct the support frame 1 vertically.

[0056] like Figure 8 As shown. Of the foot pad 3 and the support frame 1, one is provided with a hanging groove 41, and the other is provided with a hook 42 that connects to the hook 42 of the hanging groove 41.

[0057] In this embodiment, the hanging groove 41 is provided on the support leg 11, and the hook 42 is provided on the foot pad 3. Both extend laterally. During installation, the hook 42 is inserted into the hanging groove 41 laterally. After the hook 42 is in place, the two are relatively fixed in the horizontal direction and are not easy to separate. There is a gap between the hook 42 and the hanging groove 41 (especially in the vertical direction).

[0058] The bottom wall of the inner cavity 31 of the foot pad 3 is also provided with a positioning groove 32, and the bottom support part 213 is embedded in the positioning groove 32. The positioning groove 32 plays a positioning role. After the bottom support part 213 is connected to the positioning groove 32, the top support part 211 contacts the bottom end of the support leg 11.

[0059] The gravity sensor 2 also includes a first information transmission module, which is communicatively connected to the controller on the stove.

[0060] The first information transmission module can transmit the data acquired by the gravity sensor 2 to the controller of the stove, thereby facilitating subsequent automatic operation.

[0061] The first information transmission module includes a first electrical connector 23; the first electrical connector 23 is used to connect to the second electrical connection structure of the controller; the foot pad 3 is provided with a first channel 33 connecting the inside and outside of the inner cavity 31, and the first electrical connector 23 passes through the first channel 33.

[0062] like Figure 5 and Figure 11 As shown, in this embodiment, there are two first electrical connectors 23, and correspondingly, there are two first channels 33 and two second electrical connection structures 64 on the stovetop. The second electrical connection structure 64 can be installed on the stovetop, and when the pot rack is placed on the stovetop, the first electrical connectors 23 and the second electrical connection structure are vertically aligned. The first electrical connector 23 passes through the first channel 33. The foot pad 3 can be a plastic part. The first electrical connector 23 can be integrally injection molded with the foot pad 3, or the first electrical connector 23 can be inserted into the first channel 33, and adhesive can be applied between them to increase the connection strength between the first electrical connector 23 and the foot pad 3.

[0063] The deformation data of the stress section 22 can be transmitted to the controller on the stove by connecting the first electrical connection joint 23 with the second electrical connection structure. The controller includes a measuring circuit, which is used to calculate gravity data based on the deformation data.

[0064] Example 2

[0065] like Figure 12 As shown, unlike Embodiment 1, in this embodiment, the gravity sensor 2 also includes a measuring circuit and a power supply connector 5. Specifically, the measuring circuit is not located inside the stove but is also mounted on the pot rack. The measuring circuit is connected to the stress section 22 and the first electrical connection connector 23. The measuring circuit calculates gravity data based on the deformation data of the stress section 22, and the gravity data can be directly transmitted to the stove via the first electrical connection connector 23. The power supply connector 5 supplies power to the gravity sensor 2. The foot pad 3 has a second channel connecting the inside and outside of the inner cavity 31, and the power supply connector 5 passes through this second channel.

[0066] In Embodiment 1, since the measuring circuit is on the controller of the stove, the measuring circuit does not work when the controller with the measuring circuit is matched with a pot rack without a weighing sensor, resulting in a waste of cost. This embodiment solves this problem by integrating the measuring circuit on the stress unit 22. At this time, the controller only needs to provide power and information transmission to the weighing sensor to obtain the weight information, making the controller more versatile.

[0067] like Figures 9-13 As shown, the stove provided by this utility model includes the aforementioned pot rack. Because the stove provided by this utility model incorporates the aforementioned pot rack, it also possesses the advantages of a pot rack.

[0068] The controller acquires gravity data and compares it with a threshold. When the gravity value is less than the threshold, the controller can control the gas valve of the stove, thereby changing its opening degree. For example, when the water level in the unmanned cooker decreases, the gas valve can be turned off or reduced to prevent the water in the unmanned cooker from boiling dry. The specific calculation logic of the data processing module on the controller can be to calculate the amount of water evaporation in the pot based on the gravity value and feed back the open flame power, or it can be to directly compare the gravity value with a preset value, or other calculation logic. This application does not impose specific limitations on this. Therefore, this embodiment alleviates the technical problem of food burning easily in existing automatic cooking unmanned cookers.

[0069] The stove includes a water tray 6, which collects water, stains, grease and other debris generated during the use of the stove to keep the surface of the stove clean and prevent these stains from flowing into the inside of the stove and affecting its service life.

[0070] like Figure 11 and Figure 13 As shown, the water receiving tray 6 is equipped with an adapter 61, and a second electrical connection structure 64 (with a concave top) is connected to the adapter 61. The second electrical connection structure 64 is connected to the first electrical connection connector 23 in a one-to-one correspondence. The end of the first electrical connection connector 23 is a convex curved surface. The first electrical connection connector 23 and the second electrical connection structure 64 are connected in a one-to-one concave-convex fit to ensure full contact between the first electrical connection connector 23 and the second electrical connection structure 64, and to ensure the stability of the electrical connection.

[0071] like Figure 13 As shown, a limiting groove 63 is provided on the upper surface of the water receiving tray 6, and the foot pad 3 is embedded in the limiting groove 63 below; a wiring channel 62 is provided on the water receiving tray 6, which communicates with the limiting groove 63 and penetrates the lower surface of the water receiving tray 6; the adapter 61 is located inside the wiring channel 62, so as to limit the foot pad 3 through the limiting groove 63, thereby increasing the stability of the pot rack when the user uses it.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
