Description

Technical Field

[0001] This utility model relates to the field of temperature detection technology for electromagnetic cooking appliances, and in particular to a temperature sensing panel. Background Technology

[0002] Since the application of electromagnetic heating technology to the cooking industry, temperature control has always been a major challenge. The mainstream induction cooker structure usually places the temperature sensor on the bottom of the panel. Because the temperature sensor is too far from the cookware and the glass panel has low thermal conductivity, the temperature detection of this structure cannot provide real-time feedback on the cookware temperature. It can only infer the cookware temperature from the temperature change curve. However, due to the different materials, thicknesses, and ingredients in the cookware, the temperature curve varies greatly, making it impossible to accurately detect the cookware temperature. Therefore, how to reduce the lag in temperature detection and provide real-time feedback on the cookware temperature is a problem that needs to be solved. Utility Model Content

[0003] The purpose of this invention is to provide a temperature-sensing panel to solve the above-mentioned problems.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A temperature sensing panel includes a panel and a temperature sensing probe;

[0006] The panel has several through holes;

[0007] The temperature sensing probes are multiple, and each temperature sensing probe includes:

[0008] A temperature-conducting cap, comprising a connecting portion and a supporting portion, wherein the connecting portion is a tubular structure with an opening at the bottom and is provided with a first thread; the supporting portion is disposed on the top outer edge of the connecting portion;

[0009] A connecting buckle, comprising a screw portion and a limiting portion, wherein the screw portion is a tubular structure with openings at both ends, and the screw portion is provided with a second thread that mates with the first thread; the limiting portion is disposed on the outer wall of the screw portion;

[0010] A temperature sensing element is disposed within a connecting portion and abuts against the top wall of the connecting portion, the connecting portion being filled with heat-resistant adhesive.

[0011] The temperature-conducting cap is installed on the top surface of the panel, and the connecting part is inserted into the through hole;

[0012] The connecting buckle is installed on the bottom surface of the panel, the screw is inserted into the through hole and threadedly connected to the connecting part, and the connecting buckle is used to fix the temperature conducting cap to the panel and press the bottom surface of the support part against the top surface of the panel.

[0013] Preferably, the panel has a plurality of recessed grooves, and the through hole is located in each of the recessed grooves; the temperature-conducting cap is installed in the recessed groove, and the outer wall of the support part cooperates with the inner wall of the recessed groove; the top surface of the temperature-conducting cap is not lower than the top surface of the panel.

[0014] Preferably, the top periphery of the support is inclined downward so that the top edge of the support is in contact with the edge of the panel and the sink.

[0015] Preferably, the inner wall of the connecting part is provided with the first thread, the outer wall of the screw part is provided with the second thread, and the screw part is inserted into the connecting part for threaded connection;

[0016] Preferably, the inner wall of the connecting part or the outer wall of the screw part is provided with a step, the step being used to limit the depth of the screw part inserted into the connecting part.

[0017] Preferably, in a second embodiment, the inner wall of the screw portion is provided with the second thread, the outer wall of the connecting portion is provided with the first thread, and the connecting portion is inserted into the screw portion for threaded connection.

[0018] Preferably, the outer wall of the connecting part is provided with a step, which is used to limit the depth of the connecting part inserted into the screw part.

[0019] Preferably, it further includes an elastic sealing gasket, which is disposed between the bottom surface of the support and the top surface of the panel and / or between the bottom surface of the panel and the top surface of the limiting part.

[0020] Preferably, the inner top wall of the connecting portion is at least partially a thin-walled structure, and the temperature sensing element is pressed against the thin-walled structure.

[0021] One embodiment of this utility model has the following beneficial effects:

[0022] 1. Several through holes are made on the panel to allow the temperature-conducting cap to be installed on the upper surface of the panel, so that the temperature-conducting cap and the panel are fixed relative to each other in the horizontal direction. The connecting buckle is inserted into the through holes from the bottom surface of the panel and threadedly connected to the temperature-conducting cap. The threaded connection method allows the temperature probe to be installed on panels of different thicknesses. In addition, since the thickness of the panel may have errors during the manufacturing process, the distance between the bottom surface of the support and the top surface of the limiting part changes continuously during the tightening process. Therefore, even if there are errors in the thickness of the panel, the temperature probe can still clamp the panel through the bottom surface of the support and the top surface of the limiting part, thus firmly installing it on the panel.

[0023] 2. Filling the connecting part with heat-resistant adhesive not only serves to fix the temperature sensing element, but also allows air to escape from the connecting part, thus improving the heat conduction between the temperature sensing element and the temperature-conducting cap, and enabling more accurate and sensitive detection of the cooking container's temperature; the temperature sensing element abuts against the top of the connecting part, so that the temperature sensing element can be closer to the cooking container, further improving the accuracy and sensitivity of temperature detection.

[0024] 3. By setting a connecting buckle, the temperature conducting cap can be fixed to the panel through a mechanical structure, thereby better preventing the temperature conducting cap from falling off the panel. Compared with the method of gluing the temperature conducting cap to the panel, the mechanical connection method of this utility model is more reliable and the product is more stable and durable.

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] A temperature sensing panel 100 in this embodiment, such as Figure 1-6 As shown, it includes a panel 100 and a temperature sensor 200;

[0039] The panel 100 has a plurality of through holes 11;

[0040] The temperature sensing probe 200 comprises a plurality of probes, and the temperature sensing probe 200 includes:

[0041] A temperature-conducting cap 21 includes a connecting part 211 and a supporting part 212. The connecting part 211 is a tubular structure with an opening at the bottom and is provided with a first thread. The supporting part 212 is disposed on the top outer edge of the connecting part 211.

[0042] The connecting buckle 22 includes a screw portion 221 and a limiting portion 222. The screw portion 221 is a tubular structure with openings at both ends. The screw portion 221 is provided with a second thread that mates with the first thread. The limiting portion 222 is disposed on the outer wall of the screw portion 221.

[0043] Temperature sensing element 23 is disposed in the connecting part 211 and abuts against the top wall of the connecting part 211. The connecting part 211 is filled with heat-resistant adhesive 24.

[0044] The temperature-conducting cap 21 is installed on the top surface of the panel 100, and the connecting part 211 is inserted into the through hole 11;

[0045] The connecting buckle 22 is installed on the bottom surface of the panel 100, the screw part 221 is inserted into the through hole 11 and threadedly connected to the connecting part 211, and the connecting buckle 22 is used to fix the temperature conducting cap 21 to the panel 100 and press the bottom surface of the support part 212 against the top surface of the panel 100.

[0046] By creating several through holes 11 on the panel 100, the temperature-conducting cap 21 can be installed onto the upper surface of the panel 100, thus fixing the temperature-conducting cap 21 and the panel 100 relative to each other in the horizontal direction. The connecting buckle 22 passes through the through holes 11 from the bottom surface of the panel 100 and is threadedly connected to the temperature-conducting cap 21. By using a threaded connection, the temperature probe 200 can be installed on panels 100 of different thicknesses. In addition, since the thickness of the panel 100 may have errors during the manufacturing process, the temperature-conducting cap 21 and the connecting buckle 22 are connected by threads. During the tightening process, the distance between the bottom surface of the support part 212 and the top surface of the limiting part 222 changes continuously. Therefore, even if the thickness of the panel 100 has errors, the temperature probe 200 can still clamp the panel 100 through the bottom surface of the support part 212 and the top surface of the limiting part 222, thus firmly installing it onto the panel 100.

[0047] Since the temperature-conducting cap 21 is installed on the upper surface of the panel 100 and the support part 212 has a certain thickness, the temperature-conducting cap 21 protrudes from the upper surface of the panel 100. In order to prevent the cooking container from shaking when placed on the panel 100, multiple rapid temperature-sensing probes 200 can be provided on the panel 100, such as three, four, five or more rapid temperature-sensing probes 200, so that when the cooking container is placed on the panel 100, it can be supported by multiple rapid temperature-sensing probes 200 at the same time, so that the cooking container is more stable when placed on the panel 100.

[0048] Before the temperature probe 200 is installed on the panel 100, the temperature sensing element 23 is placed inside the connecting part 211, and heat-resistant adhesive 24 is filled into the connecting part 211 to fix the temperature sensing element 23. The heat-resistant adhesive 24 refers to an adhesive that can meet the temperature requirements of actual applications, such as silicone adhesive. Filling the connecting part 211 with heat-resistant adhesive 24 not only fixes the temperature sensing element 23, but also removes air from the connecting part 211, so as to improve the heat conduction effect between the temperature sensing element 23 and the temperature-conducting cap 21, so as to detect the temperature of the cooking container more accurately and sensitively. The temperature sensing element 23 abuts against the top of the connecting part 211 so that the temperature sensing element 23 can be closer to the cooking container, thereby further improving the accuracy and sensitivity of temperature detection. As one implementation method, the temperature-conducting cap 21 can be made of metal materials such as aluminum, stainless steel, or copper, which not only have good thermal conductivity but are also relatively wear-resistant. Of course, the temperature-conducting cap 21 can also be made of engineering plastics, such as PEEK plastic.

[0049] The connecting part 211 of the temperature-conducting cap 21 is inserted into the through hole 11 from the upper surface of the panel 100, and the bottom surface of the support part 212 is supported on the upper surface of the panel 100; while the connecting buckle 22 is inserted into the through hole 11 from the bottom surface of the panel 100. The connecting buckle 22 is interlocked and fixed with the connecting part 211 of the temperature-conducting cap 21 through the buckle body part. The limiting part 222 abuts against the bottom surface of the panel 100. The panel 100 is clamped by the support part 212 and the limiting part 222, so that the rapid temperature sensing probe 200 can be completely fixed to the panel 100 in the vertical direction. By providing a connecting buckle 22, this utility model allows the temperature-conducting cap 21 to be fixed to the panel 100 via a mechanical structure, thereby better preventing the temperature-conducting cap 21 from falling off the panel 100. Compared to gluing the temperature-conducting cap 21 to the panel 100 with adhesive, this utility model's mechanical connection method offers better reliability and makes the product more stable and durable. As one embodiment, the temperature-sensing element 23 can be a thermistor. To enable the temperature-sensing element 23 to connect with the electrical components below the panel 100, the buckle body is designed as a tubular structure with openings at both ends, allowing the connecting wires to the temperature-sensing element 23 to pass through the inside of the buckle body and make an electrical connection with the electrical components below the panel 100.

[0050] As one example, such as Figure 2-5 As shown, the panel 100 has a plurality of recesses 12, and the through hole 11 is located in each of the recesses 12; the temperature-conducting cap 21 is installed in the recesses 12, and the outer wall of the support 212 is engaged with the inner wall of the recesses 12; the top surface of the temperature-conducting cap 21 is not lower than the top surface of the panel 100.

[0051] By creating a recess 12 on the panel 100, the temperature-conducting cap 21 can be embedded and installed within the recess 12. To ensure the temperature sensor 200 can accurately detect the temperature of the cooking container, the temperature sensor 200 needs to be in contact with the cooking container. To achieve this, after the temperature sensor 200 is installed on the panel 100, the top of the temperature sensor 200 is not lower than the top surface of the panel 100, i.e., the temperature sensor 200 protrudes from the panel 100 (e.g., ...). Figure 2-4 (As shown) or the top surface of the temperature-conducting cap 21 is flush with the panel 100 (as shown). Figure 5 (As shown); In one embodiment, the temperature probe 200 protrudes from the panel 100. To prevent the cooking container from wobbling when placed on the panel 100, multiple temperature probes 200 can be provided on the panel 100, such as three, four, five, or more. This allows the cooking container to be supported by multiple temperature probes 200 when placed on the panel 100, making the cooking container more stable and enabling more accurate temperature detection through multi-point temperature measurement. In another embodiment, the top surface of the temperature-conducting cap 21 is flush with the panel 100, and at least one temperature probe 200 is required. Of course, to better detect the temperature at various points on the bottom of the cooking container, the number of temperature probes 200 can be increased accordingly, and more accurate temperature data can be obtained through multi-point temperature measurement.

[0052] Furthermore, the top periphery of the support portion 212 is inclined downward so that the top edge of the support portion 212 is in contact with the edge of the panel 100 at the edge of the recess 12.

[0053] This allows for a smooth transition between the top surface of the temperature-conducting cap 21 and the panel 100, facilitating easy cleaning when liquid is spilled on the panel 100 at the temperature sensor 200. As one implementation method, for example... Figure 3 and Figure 4 As shown, the top perimeter of the support portion 212 is concave and slopes downwards in an arc shape, and smoothly transitions at the junction with the panel 100, thus making it less prone to accumulating dirt; as another embodiment, such as Figure 2 As shown, the top of the support 212 is tapered and slopes downwards, and the support 212 forms an obtuse angle with the panel 100, which also makes it easier to clean.

[0054] As one embodiment of the connection method between the temperature-conducting cap 21 and the connecting buckle 22, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 The inner wall of the connecting part 211 shown is provided with the first thread, and the outer wall of the screw part 221 is provided with the second thread. The screw part 221 is inserted into the connecting part 211 for threaded connection.

[0055] Furthermore, the inner wall of the connecting part 211 or the outer wall of the screw part 221 is provided with a step 2211, which is used to limit the depth of the screw part 221 inserted into the connecting part 211.

[0056] Since the temperature sensing element 23 is located inside the connecting part 211 and is relatively fragile, if the screw part 221 is inserted into the connecting part 211 to an excessive depth, the screw part 221 may easily crush the temperature sensing element 23. To avoid this problem, this invention provides a step 2211 on the outer wall of the screw part 221 or the inner wall of the connecting part 211. By utilizing the limiting effect of the step 2211, the depth of the screw part 221 inserted into the connecting part 211 can be limited, thereby effectively preventing the temperature sensing element 23 from being crushed. Moreover, since the panel 100 of the electromagnetic cooking appliance is usually made of glass, limiting the depth of the screw part 221 inserted into the connecting part 211 can also limit the distance between the bottom surface of the support part 212 and the top surface of the limiting part 222, preventing the panel 100 from being crushed due to excessive tightening when the screw part 221 is screwed into the connecting part 211.

[0057] As another embodiment of the connection method between the temperature-conducting cap 21 and the connecting buckle 22, such as Figure 4 As shown, in a second embodiment, the inner wall of the screw portion 221 is provided with the second thread, the outer wall of the connecting portion 211 is provided with the first thread, and the connecting portion 211 is inserted into the screw portion 221 for threaded connection.

[0058] Furthermore, the outer wall of the connecting part 211 is provided with a step 2211, which is used to limit the depth of the connecting part 211 inserted into the screw part 221.

[0059] Similarly, by providing a step 2211 on the outer wall of the connecting part 211, the depth to which the screw part 221 is inserted into the connecting part 211 can be limited, thereby preventing the panel 100 from being crushed due to excessive tightening when the screw part 221 is screwed into the connecting part 211. In addition, providing a step 2211 on the outer wall of the connecting part 211 allows the outer wall of the step 2211 to mate with the inner wall of the through hole 11, thereby limiting the horizontal movement of the temperature-conducting cap 21, preventing the temperature-conducting cap 21 from shaking, and also reducing the gap between the connecting part 211 and the through hole 11, thus achieving the aforementioned waterproof effect.

[0060] Preferably, it further includes an elastic sealing gasket 25, which is disposed between the bottom surface of the support portion 212 and the top surface of the panel 100 and / or between the bottom surface of the panel 100 and the top surface of the limiting portion 222.

[0061] The elastic sealing gasket 25 can play a sealing role. When water, soup or other liquids are spilled on the panel 100, the elastic sealing gasket 25 can prevent liquid from flowing into the bottom of the panel 100 through the through hole 11, avoiding water ingress and short circuit of electrical components under the panel 100. In addition, the elastic sealing gasket 25 can be pressed tightly after the temperature conducting cap 21 and the connecting buckle 22 are tightened, and the elastic sealing gasket 25 will undergo elastic deformation, so that the temperature probe 200 is not prone to loosening of the threaded connection between the temperature conducting cap 21 and the connecting buckle 22 due to vibration or other reasons during long-term use.

[0062] Preferably, the inner top wall of the connecting portion 211 is at least partially a thin-walled structure 2111, and the temperature sensing element 23 abuts against the thin-walled structure 2111.

[0063] The inner top wall of the connecting part 211 is at least partially a thin-walled structure 2111, and the temperature sensing element 23 is pressed against the thin-walled structure 2111. With this arrangement, the temperature sensing element 23 can be brought closer to the cooking container while ensuring that the temperature-conducting cap 21 has good strength, thereby further improving the accuracy and sensitivity of temperature detection.
