The advantage of stir-fry is turned over fast that compound pot in this embodiment possesses the round bottom pot, and possesses the easy advantage of placing of pan for this compound pot can be on the electromagnetism stove stable use, can carry out accurate temperature measurement to this compound pot.

It should be noted that, in the present embodiment, the composite pan is formed by compounding three layers of pans, i.e., the inner layer 10, the middle layer 20 and the outer layer 30, instead of the inner layer 10, the middle layer 20 and the outer layer 30 which are formed by compounding separately through a process.

Specifically, the composite pan further comprises at least one sensor 40 and a sensor protection device 70, the middle layer 20 is provided with a groove for accommodating the sensor 40 in advance, and the sensor protection device 70 is sleeved outside the sensor 40 and is located in the groove. By arranging the groove on the middle layer 20 to accommodate the sensor 40, the sensor 40 can be effectively prevented from being damaged when the inner layer 10, the middle layer 20 and the outer layer 30 are welded in a composite mode, the sensor protection device 70 can effectively protect the sensor 40 from being damaged by external pressure in the welding process, and the yield of the composite cooker is increased. The preferred sensor 40 is a temperature sensor, which may be a thermocouple, a thermal resistor, or a thermistor. Of course, the sensor 40 may be a humidity sensor, a gravity sensor, or the like.

Specifically, the intermediate layer 20 is a metal layer.

It should be noted that, because the heated temperature of the different points of the pot is different, the sensor corresponds to the preset position of the induction cooker, so that the pot can be heated better, the pot temperature corresponding to the induction cooker setting point in the preset food material temperature algorithm can be obtained more favorably, and the preset algorithm can calculate the food material temperature according to the preset position temperature.

Of course, in the embodiment not shown in the drawings, the composite pan may be formed by not only three layers of pans, but also more than three layers, such as five layers, seven layers, and so on. The specific number of layers is determined according to the use requirement of the composite pan, and in addition, the number of the sensors 40 and the number of the grooves can also be multiple, but the number and the number of the layers of the sensors 40 do not necessarily correspond, and the specific number of the layers can be determined according to the use requirement of the composite pan.

Specifically, the length of the sensor protector 70 is less than the total length of the sensor 40 and the connecting wires, so that the probe portion of the sensor 40 is exposed. The probe of the sensor 40 is exposed outside the sensor protection device 70, so that the probe of the sensor 40 is directly contacted with the pot bottom of the composite pot, and the temperature measurement of the sensor 40 is more accurate.

In the embodiment shown in fig. 5, the sensor protector 70 is a sheet-like structure having a receiving groove adapted to the sensor 40, so that the probe of the sensor 40 is exposed when the sensor 40 is mounted in the sheet-like structure. Since the sheet structure covers the sensor 40, the composite interlayer 20 is isolated from surface contact with the sensor 40, and the connecting wires of the sensor 40 are effectively protected from being broken.

As shown in fig. 5, the sheet structure is welded on a surface of the inner layer 10 on a side close to the intermediate layer 20 and/or on a surface of the outer layer 30 on a side close to the intermediate layer 20. The sensor 40 can be directly contacted with the inner layer 10 and/or the outer layer 30, so that the temperature measurement is more accurate.

In one embodiment, not shown, the sensor protector 70 is a tubular structure through which the sensor 40 is disposed with the probe portion of the sensor 40 exposed. And the tubular structure with the sensor 40 is placed into the recess of the intermediate layer 20 so that the sensor 40 is fixed.

Optionally, the tubular structure extends along the bottom wall and/or the side wall of the composite pan. To protect the connection wires of the sensor 40. Of course the length of the tubular structure can also be designed to the edge of the middle layer and the sensor 40 connection lines along the side walls can be protected by other means.

As shown in fig. 2-4, at least one sensor 40 is attached to the bottom wall of the inner layer 10 and at least another sensor 40 is attached to the bottom wall of the outer layer 30. Specifically, sensor 40 is attached to the inner surface of the bottom wall of outer layer 30. Let at least one sensor 40 laminate on the diapire of inlayer 10 and at least another sensor 40 laminate on the diapire of skin 30, can make the effective real-time temperature of inlayer 10 and skin 30 that two sensors 40 measured respectively, gather the effective temperature of inlayer 10 and skin 30, can accurately surmise out the maturity of the interior edible material of pot according to the effective real-time temperature that measures to the duration and the culinary art time of accurate control cooking equipment.

As shown in fig. 2 and 3, at least one sensor 40 is located at the center of the middle layer 20, and the at least one sensor 40 is disposed at a predetermined distance from the center of the middle layer 20. Specifically, the sensor 40 is located on the inner surface of the middle layer 20, and the sensor 40 is respectively arranged at different positions of the bottom wall of the middle layer 20, so that the sensor 40 can monitor the temperatures of the different positions of the bottom wall, and the duration and cooking time of the cooking device can be accurately controlled. The two sensors 40 are staggered by a certain distance, that is, the two sensors 40 are not on the same vertical line, so that the temperature at different positions can be measured.

Specifically, the outer periphery of the groove and/or the interior of the groove is provided with a positioning structure for fixing the sensor 40. The positioning structure in the groove is fixed by small points, so that the sensor 40 can be fixed on the middle layer 20, and the sensor 40 is prevented from being out of position in the welding process, so that the sensor 40 cannot work accurately. Specifically, the dots may be formed on the outer periphery of the groove or in the groove, or the dots may be formed on the outer periphery of the groove or in the groove by resistance welding.

Optionally, the inner layer 10, the middle layer 20 and the outer layer 30 are formed by at least one of pressure welding, brazing or cold composite welding. The pressure welding includes resistance welding, friction press welding, electric screw press welding, or the like. It can be shown that the groove and embedded sensor 40 can be adapted to a variety of welding processes when the inner layer 10, the intermediate layer 20 and the outer layer 30 are welded.

Alternatively, after the inner layer 10, the intermediate layer 20 and the outer layer 30 are fixed by resistance welding, the intermediate layer 20 is softened by heating and then the three are combined together by pressure welding so that the intermediate layer 20 is deformed to fill the gap of the groove. The intermediate layer 20 deforms to fill the gap of the groove, so that the sensor protection device 70 is connected with the intermediate layer 20 in a seamless mode, inaccurate temperature measurement caused by the fact that the sensor protection device 70 shakes in the groove is avoided, and the accuracy of temperature measurement of the sensor 40 is improved. After the inner layer 10, the middle layer 20 and the outer layer 30 are fixed through resistance welding, the three are heated at the intermediate frequency, the three are punched and compounded together through a press, the middle layer 20 is filled in a cavity between the inner layer 10 and the outer layer 30 at the moment, the production efficiency is high, the yield is high, particularly, the binding force of the three is high, and the situation that the composite pot cannot be out of the bottom in subsequent use is guaranteed.

As shown in fig. 1, the composite pan further includes a polishing protector sheet 50, and the polishing protector sheet 50 fixes the connection line of the sensor 40 to the side wall of the inner layer 10 to prevent the connection line of the sensor 40 from being torn during polishing. The polishing protection sheet 50 can fix the connection wires of the sensor 40 to the side walls of the inner layer 10 to prevent the connection wires of the sensor from being torn during polishing, thereby increasing the service life of the whole set of the device. The connecting wire of the sensor 40 can be connected to a handle, and a chip main board is arranged at the handle to collect, read, display and process the temperature measured by the sensor 40 and feed back and control the cooking equipment.

As shown in fig. 1, the sidewalls of the outer layer 30 completely envelope the sidewalls of the intermediate layer 20; and/or neither the side walls of the outer layer 30 nor the side walls of the intermediate layer 20 completely cover the side walls of the inner layer 10. The outer layer 30 can completely cover the middle layer 20 on the inner layer 10, so that the middle layer 20 is deformed between the inner layer 10 and the outer layer 30 during welding and is not exposed outside, and the overall attractiveness of the composite pot is improved.

Specifically, the inner layer 10 is made of a heat conductive metal material; and/or the intermediate layer 20 is made of aluminum or copper or a combination thereof; and/or the outer layer 30 is made of a magnetically permeable material. The intermediate layer can be a plurality of layers, and the material of the intermediate layer can be single aluminum or copper, or the copper and the aluminum are paved at intervals. Preferably, the inner layer 10 is made of a stainless steel material, and the intermediate layer 20 is made of an aluminum material. The stainless steel material for the inner layer 10 can prevent the composite pot from rusting in the using process, and the stainless steel material can be heated quickly. The reason why the aluminum material is used as the intermediate layer 20 is that the aluminum material has good thermal conductivity to rapidly transfer the heat of the outer layer 30 to the inner layer 10, and the aluminum material has good ductility to be filled in the gap of the groove after being heated, and the magnetic conductive material used as the outer layer 30 is convenient for the composite pot to be used on the induction cooker. Specifically, the magnetic conductive material is stainless iron, and other materials with good magnetic conductivity can be used. The inner layer 10 is made of a material having good thermal conductivity so that the inner layer 10 can conduct heat well. The intermediate layer 20 is made of a material that is softer so that the intermediate layer 20 can fill the gap of the groove after being heated.

As shown in fig. 1, the induction cooker includes an induction heating panel 60 and an induction heating coil, wherein the side wall of the induction heating panel 60 is a cambered surface structure, the bottom wall of the induction heating panel 60 is a flat surface structure to fit the above-mentioned composite pan, and the induction heating coil heats the induction heating panel 60. When the composite pot is matched with an induction cooker for use, the temperature measurement accuracy of the sensor 40 in the composite pot can be ensured.

Specifically, the radian of the arc-shaped structure of the side wall of the electromagnetic heating panel 60 is consistent with the radian of the arc-shaped structure of the side wall of the outer layer 30 of the composite pan. The combined structure of the concave arc shape of the composite pan and the horizontal bottom edge is ensured, so that the bottom plane of the composite pan is positioned at the bottom plane of the induction cooker, and the positioning accuracy and the heating efficiency are ensured.

The invention also provides a fixed-point temperature measurement method for the induction cooker. The fixed-point temperature measurement method for the induction cooker comprises the following steps: step S1, placing the composite pan in the induction cooker so as to position the composite pan at a preset position of the induction cooker, wherein the composite pan is the induction cooker, and the induction cooker is the induction cooker; step S2, acquiring data of the sensor 40 in the composite pan according to the position of the positioned composite pan; and step S3, calculating the temperature of the composite boiler and/or the maturity of the food material according to the acquired data of the sensor 40. The composite pot and the induction cooker can contain fixed induction cooker position related parameters, sensor temperature measurement parameters and the like, and the composite pot can be placed at the correct position of the induction cooker to calculate the data such as the temperature of the composite pot more accurately.
