Description

[0002] Since the electromagnetic heating technology was applied to the cooking industry, temperature control has always been a big problem. The mainstream induction cooker structure usually sets a temperature sensor on the bottom of the panel. Since the temperature sensor is too far away from the pot and the thermal conductivity of the glass panel is low, the temperature detection of this structure cannot provide real-time feedback on the temperature of the pot. The temperature of the pot can only be inferred through the temperature change curve. However, due to the different materials and thickness of the pot and the ingredients in the pot, the temperature curve is ever-changing, so it is impossible to accurately detect the temperature of the pot. Therefore, how to reduce the lag of temperature detection and feedback the temperature of the pot as real-time as possible is a problem that needs to be solved at present. Summary of the invention

[0038] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0039] The first aspect of the present invention discloses a rapid temperature sensing probe, such as Figure 1-6 As shown, including:

[0040] A thermal conductive cap 1, comprising a connecting portion 11 and a supporting portion 12, wherein the connecting portion 11 is a tubular structure with an opening at the bottom, the supporting portion 12 is arranged at the top outer edge of the connecting portion 11, and a convex ring 121 is arranged on the bottom surface of the supporting portion 12;

[0041] The connecting buckle 2 includes a buckle body 21 and a limiting portion 22. The buckle body 21 is a tubular structure with openings at both ends. The limiting portion 22 is arranged on the outer wall of the buckle body 21. The upper end of the buckle body 21 and the lower end of the connecting portion 11 are plugged and fixed to each other.

[0042] The temperature sensing element 3 is disposed in the connecting portion 11 , and the temperature sensing element 3 abuts against the top wall of the connecting portion 11 , and the connecting portion 11 is filled with a temperature-resistant glue 4 .

[0043] The rapid temperature sensing probe of the present invention is installed on the panel 6 of the electromagnetic cooking appliance (such as an induction cooker and an IH rice cooker, etc.) to detect the temperature of the cooking container placed on the electromagnetic cooking appliance. A plurality of rapid temperature sensing probes of the present invention may be installed on the panel 6, such as three, four, five, etc. By installing a plurality of rapid temperature sensing probes, the temperature of the cooking container may be measured at multiple points, and the temperature detection is more accurate. Before installing the rapid temperature sensing probe, the temperature sensing element 3 is first placed in the connecting portion 11, and the temperature-resistant glue 4 is filled into the connecting portion 11 to fix the temperature sensing element 3. The temperature-resistant glue 4 refers to glue that can meet the temperature requirements in actual application, such as silicone glue. Filling the connection part 11 with the heat-resistant glue 4 can not only fix the temperature sensing element 3, but also discharge the air in the connection part 11, so as to make the heat conduction effect between the temperature sensing element 3 and the temperature conductive cap 1 better, so as to detect the temperature of the cooking container more accurately and sensitively; the temperature sensing element 3 is abutted against the top of the connection part 11, so that the temperature sensing element 3 can be closer to the cooking container, so as to further improve the accuracy and sensitivity of temperature detection. As one of the implementation modes, the temperature conductive cap 1 can be made of metal materials such as aluminum, stainless steel, copper, etc., which not only have good thermal conductivity but also are relatively wear-resistant; of course, the temperature conductive cap 1 can also be made of engineering plastics, such as PEEK plastic.

[0044] In order to install the rapid temperature sensing probe of the present invention on the panel 6, it is necessary to pre-open an annular groove 61 and a through hole 62 located in the annular groove 61 and penetrating up and down on the upper surface of the panel 6; the connecting portion 11 of the thermal conductive cap 1 is inserted into the through hole 62 from the upper surface of the panel 6, the convex ring 121 is inserted into the annular groove 61, and the bottom surface of the support portion 12 is supported on the upper surface of the panel 6; and the connecting buckle 2 is inserted into the through hole 62 from the bottom surface of the panel 6, and the connecting buckle 2 is fixedly engaged with the connecting portion 11 of the thermal conductive cap 1 through the buckle body 21, and the limiting portion 22 is against the bottom surface of the panel 6. The panel 6 is clamped by the supporting portion 12 and the limiting portion 22, so that the rapid temperature sensing probe can be completely fixed to the panel 6 in the vertical direction. The present invention can fix the thermal cap 1 on the panel 6 through a mechanical structure by providing a connecting buckle 2, thereby better preventing the thermal cap 1 from falling off the panel 6. Compared with the method of gluing the thermal cap 1 to the panel 6 with glue, the reliability of the present invention through mechanical connection is better, and the product is more stable and durable. As one of the embodiments, the temperature sensing element 3 can be a thermistor. In order to connect the temperature sensing element 3 with the controller (such as a circuit board) in the electromagnetic cooking appliance, the buckle body 21 is configured as a tubular structure with openings at both ends, so that the connecting wire with the temperature sensing element 3 can pass downward from the inside of the buckle body 21 and be electrically connected to the controller in the electromagnetic cooking appliance.

[0045] As one example, Figure 1 , Figure 3 and Figure 4As shown, the inner wall of the connecting portion 11 is provided with a slot 111 , the outer wall of the buckle body 21 is provided with a protruding buckle 211 , and the upper end of the buckle body 21 is inserted into the connecting portion 11 so that the buckle 211 and the slot 111 are buckled.

[0046] In this embodiment, the inner wall of the connecting part 11 cooperates with the outer wall of the buckle body 21 so that the buckle body 21 can be inserted into the connecting part 11, and the buckle 211 on the outer wall of the buckle body 21 is buckled with the groove 111 on the inner wall of the connecting part 11. It should be pointed out that since the connecting part 11 and the buckle body 21 are both tubular structures with a small thickness of their side walls, when the buckle body 21 is inserted into the connecting part 11, both the connecting part 11 and the buckle body 21 can undergo a certain elastic deformation, so that even if the outer wall of the buckle body 21 is provided with a protruding buckle 211, it can be inserted into the connecting part 11 to realize the buckle 211 connection.

[0047] Furthermore, a first guiding inclined surface 112 is provided at the lower end of the inner wall of the connecting portion 11 , and a second guiding inclined surface 212 is provided at the top of the outer wall of the buckle body 21 ; and the clamping groove 111 is an inverted tooth structure.

[0048] By setting the first guiding bevel 112 and the second guiding bevel 212, the connecting part 11 and the buckle body 21 can play a guiding role when plugging together, so that the buckle body 21 can be better inserted into the connecting part 11; the card slot 111 is set to be in the shape of an inverted tooth, so that the connecting part 11 and the buckle body 21 are not easy to loosen after being plugged in and fixed, which can better avoid the problem of the thermal conductive cap 1 falling off.

[0049] Furthermore, a step 213 is provided on the outer wall of the buckle body 21 or the inner wall of the connecting portion 11 , and the step 213 is used to limit the depth of the buckle body 21 inserted into the connecting portion 11 .

[0050] Since the temperature sensing element 3 is arranged in the connecting part 11 and the temperature sensing element 3 is relatively fragile, if the buckle body 21 is inserted into the connecting part 11 to a great depth, the buckle body 21 will easily crush the temperature sensing element 3. In order to avoid this problem, the present invention provides a step 213 on the outer wall of the buckle body 21 or the inner wall of the connecting part 11. By utilizing the limiting effect of the step 213, the depth of the buckle body 21 inserted into the connecting part 11 can be limited, thereby effectively preventing the temperature sensing element 3 from being crushed. Moreover, since the panel 6 of the electromagnetic cooking appliance is usually made of glass, limiting the depth of the buckle body 21 inserted into the connecting part 11 can also limit the distance between the bottom surface of the supporting part 12 and the top surface of the limiting part 22, thereby preventing the thermal conductive cap 1 and the connecting buckle 2 from crushing the panel 6 during installation.

[0051] As a parallel embodiment of the above embodiment, Figure 2As shown, the inner wall of the buckle body 21 is provided with a slot 111, the outer wall of the connecting part 11 is provided with a protruding buckle 211, and the lower end of the connecting part 11 is inserted into the buckle body 21 so that the buckle 211 and the slot 111 are buckled.

[0052] As another embodiment, the connecting part 11 can also be inserted into the buckle body 21. In this embodiment, the outer wall of the connecting part 11 cooperates with the inner wall of the buckle body 21 so that the connecting part 11 can be inserted into the buckle body 21 to achieve the buckle fixation of the buckle 211 and the slot 111.

[0053] Furthermore, a first guiding inclined surface 112 is provided at the lower end of the outer wall of the connecting portion 11 , and a second guiding inclined surface 212 is provided at the top of the inner wall of the buckle body 21 ; and the clamping groove 111 is an inverted tooth structure.

[0054] By setting the first guiding bevel 112 and the second guiding bevel 212, the connecting part 11 and the buckle body 21 can play a guiding role when plugging together, so that the buckle body 21 can be better inserted into the connecting part 11; the card slot 111 is set to be in the shape of an inverted tooth, so that the connecting part 11 and the buckle body 21 are not easy to loosen after being plugged in and fixed, which can better avoid the problem of the thermal conductive cap 1 falling off.

[0055] Furthermore, a step 213 is provided on the outer wall of the connecting portion 11 , and the step 213 is used to limit the depth of the connecting portion 11 inserted into the buckle body 21 .

[0056] In this embodiment, limiting the depth of the connection portion 11 inserted into the buckle body 21 can limit the distance between the bottom surface of the support portion 12 and the top surface of the limiting portion 22, thereby preventing the thermal conductive cap 1 and the connecting buckle 2 from crushing the panel 6 during installation.

[0057] It can be understood that it also includes an elastic sealing pad 5, and the bottom surface of the support portion 12 is recessed upward in the area surrounded by the convex ring 121;

[0058] The elastic sealing pad 5 is sleeved on the connecting portion 11 and located on the bottom surface of the recessed area surrounded by the convex ring 121, or the elastic sealing pad 5 is sleeved on the buckle body 21 and located on the upper surface of the limiting portion 22;

[0059] At least a portion of the inner top wall of the connecting portion 11 is a thin-walled structure 113 , and the temperature sensing element 3 is pressed against the thin-walled structure 113 .

[0060] Since an annular groove 61 needs to be provided on the panel 6 to cooperate with the convex ring 121, the load-bearing capacity of the area within the annular groove 61 decreases due to the existence of the annular groove 61. The present invention can make the bottom surface of the support part 12 have a height difference between the inner side and the outer side of the convex ring 121 by making the area surrounded by the convex ring 121 concave upward. When the thermal conductive cap 1 is installed on the panel 6, the bottom surface of the support part 12 on the outer side of the convex ring 121 is supported on the upper surface of the panel 6, while the bottom surface of the support part 12 on the inner side of the convex ring 121 is suspended above the upper surface of the panel 6; in this way, when the thermal conductive cap 1 bears the weight of the cooking container, it can be supported on the panel 6 through the bottom surface outside the convex ring 121, thereby avoiding the area surrounded by the annular groove 61 from being subjected to force, and thus enabling the panel 6 to withstand greater impact force. The elastic sealing pad 5 can play a buffering role, so that when the thermal conductive cap 1 and the connecting buckle 2 are assembled to the panel 6, the impact force on the panel 6 is large at the moment of buckling, which may cause the panel 6 to break; of course, the elastic sealing pad 5 can also absorb the processing error, so that the thermal conductive cap 1 and the connecting buckle 2 are not easy to shake after being assembled to the panel 6, and can play a certain waterproof role. The inner top wall of the connecting part 11 is at least partially a thin-walled structure 113, and the temperature sensing element 3 is pressed against the thin-walled structure 113. Through such an arrangement, the temperature sensing element 3 can be further close to the cooking container while ensuring that the thermal conductive cap 1 has good strength, and the accuracy and sensitivity of temperature detection are further improved.

[0061] The second aspect of the present invention discloses a rapid temperature sensing panel, comprising a panel 6 and a plurality of rapid temperature sensing probes as described above, wherein the panel 6 is provided with a plurality of annular grooves 61, and a through hole 62 is provided in the area surrounded by the annular grooves 61;

[0062] The thermal conductive cap 1 is mounted on the upper surface of the panel 6, the connecting portion 11 is inserted into the through hole 62, the outer wall of the connecting portion 11 cooperates with the inner wall of the through hole 62, the convex ring 121 is inserted into the annular groove 61, and the convex ring 121 cooperates with the annular groove 61; a gap is left between the bottom of the convex ring 121 and the bottom of the annular groove 61, the bottom surface of the supporting portion 12 is supported on the upper surface of the panel 6, and a gap is left between the bottom surface of the area surrounded by the convex ring 121 and the upper surface of the panel 6;

[0063] The connecting buckle 2 is installed on the bottom surface of the panel 6, the buckle body 21 is inserted into the through hole 62 and plugged and buckled with the connecting part 11, and the connecting buckle 2 is used to fix the thermal conductive cap 1 to the panel 6 and press the bottom surface of the supporting part 12 against the top surface of the panel 6.

[0064] By providing an annular groove 61 and a through hole 62 on the panel 6, the thermal conductive cap 1 can be installed on the upper surface of the panel 6, so that the thermal conductive cap 1 and the panel 6 are relatively fixed in the horizontal direction, and the connecting buckle 2 is inserted into the through hole 62 from the bottom surface of the panel 6 and plugged and buckled with the thermal conductive cap 1, and the panel 6 is clamped by the bottom surface of the support part 12 and the top surface of the limit part 22, so that the rapid temperature sensing probe and the panel 6 are relatively fixed in the vertical direction; since the thermal conductive cap 1 is installed on the upper surface of the panel 6, and the support part 12 has a certain thickness, the thermal conductive cap 1 protrudes from the upper surface of the panel 6, in order to prevent the cooking container from shaking when placed on the panel 6, a plurality of rapid temperature sensing probes can be arranged on the panel 6, such as three, four, five or more rapid temperature sensing probes, so that when the cooking container is placed on the panel 6, it can be supported by a plurality of rapid temperature sensing probes at the same time, so that the cooking container is placed on the panel 6 more stably.

[0065] Due to the existence of the annular groove 61, the bottom of the annular groove 61 and the area surrounded by the annular groove 61 are relatively fragile, and the impact resistance is worse than that of the area outside the annular groove 61. In order to make the rapid temperature sensing panel 6 have better impact resistance, the bottom surface of the support part 12 is supported on the upper surface of the panel 6, and a gap is left between the bottom of the convex ring 121 and the bottom of the annular groove 61, and a gap is left between the bottom surface of the support part 12 in the area surrounded by the convex ring 121 and the upper surface of the panel 6. In this way, the thermal conductive cap 1 can be prevented from being supported on the panel 6 in the area surrounded by the annular groove 61, so that the rapid temperature sensing panel 6 can obtain better impact resistance.

[0066] Since a through hole 62 is provided on the upper surface of the panel 6, in order to make the rapid temperature sensing panel 6 of the present invention have a certain waterproof performance, a convex ring 121 is provided on the bottom surface of the support portion 12 of the present invention, and an annular groove 61 is provided on the upper surface of the panel 6, the annular groove 61 cooperates with the convex ring 121 (that is, when the thermal conductive cap 1 is assembled on the panel 6, the outer wall of the annular groove 61 fits with the outer wall of the convex ring 121 and / or the inner wall of the annular groove 61 fits with the inner wall of the convex ring 121), and the connecting portion 11 cooperates with the through hole 62 (that is, the outer wall of the connecting portion 11 fits with the inner wall of the through hole 62). Through such an arrangement, a multi-section curved path can be formed between the thermal conductive cap 1 and the panel 6, and the path is narrower at one end on the upper surface of the panel 6 and at one end located in the through hole 62, so that liquid spilled on the panel 6 is more difficult to Through; since there is a gap between the bottom of the convex ring 121 and the bottom of the annular groove 61, and there is a gap between the bottom surface of the support portion 12 in the area surrounded by the convex ring 121 and the upper surface of the panel 6, there is a certain amount of air in the bottom of the annular groove 61 and the area surrounded by the convex ring 121 in the path, so that the path is narrower at both ends, there are multiple bends in the middle and there are certain air in two areas. Through such an arrangement, the path can have a certain amount of air resistance. When liquid (such as water, soup or porridge water, etc.) is sprinkled on the panel 6, due to the air resistance in the path between the thermal conductive cap 1 and the panel 6, the liquid on the panel 6 cannot flow along the path to the bottom of the panel 6 without external pressure, so that the panel 6 can be waterproofed without gluing between the thermal conductive cap 1 and the panel 6. Of course, in order to test the waterproof performance of the structure, a cylinder is arranged on the upper surface of the panel 6, and each rapid temperature sensing probe installed on the panel 6 is surrounded in the cylinder, and glass glue is applied between the panel 6 and the cylinder for waterproofing, and then water is poured into the cylinder. After standing for 24 hours, no water seepage was observed on the bottom surface of the panel 6.

[0067] A third aspect of the present invention discloses an electromagnetic cooking appliance, which comprises the rapid temperature sensing panel as described above.
