DETAILED DESCRIPTION

[0030] The following specific embodiments are merely explanations of the present application and are not limitations of the present application. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present application, they are protected by the patent law.

[0031] Figure 1 The utility model shows an electromagnetic cooking utensil with reliable temperature measurement, comprising a panel 1 and a base 2, wherein the base 2 is provided with an electromagnetic wire reel 3 and a temperature measuring component 4, wherein the temperature measuring component 4 comprises a shell 41 and a temperature measuring circuit board 42 arranged in the shell 41, wherein outward-turned ears 43 are arranged on both sides of the shell 41, and a bearing platform 22 and a fixing platform 21 are provided on the base 2, wherein the outward-turned ears 43 are fixedly connected to the fixing platform 21, and the bearing platform 22 supports the bottom surface of the shell 41. In this way, on the one hand, the shell 41 of the temperature measuring component 4 is supported by the support platform 22 and the fixed platforms 21 on both sides, thereby improving the installation stability of the shell 41 on the base 2, and being able to provide sufficient supporting force when the temperature measuring component 4 is squeezed to prevent the shell 41 from causing positional deviation, thereby minimizing the positional deviation of the temperature measuring component 4 as much as possible, reducing the deviation of the temperature measuring field of view, and improving the temperature measurement accuracy; on the other hand, the fixed platform 21 and the support platform 22 jointly support the temperature measuring component 4, so that the temperature measuring component 4 is in a suspended state as a whole, which is conducive to increasing the heat dissipation area of ​​the shell 41 of the temperature measuring component 4, allowing the shell 41 to dissipate heat in all directions around, and reducing the influence of the temperature rise of the surrounding air and the temperature rise of the temperature measuring component 4 itself on the temperature measurement accuracy.

[0032] In one embodiment, a drainage hole is provided under the supporting platform 22. In this way, even if water enters the area on the base 2 near the temperature measuring component 4 during the cooking process, it can be discharged through the drainage hole under the supporting platform 22, thereby preventing water from invading the temperature measuring component 4 and affecting the temperature measuring component 4, thereby ensuring the operating stability of the temperature measuring component 4.

[0033] Among the three supports of the shell 41 of the temperature measuring component 4 in the present invention, the two supports provided by the fixed connection between the fixing platform 21 and the outward-turned ears 43 on both sides of the shell 41 have the functions of fastening, positioning and limiting, and their stability is relatively high, while the one support provided by the bottom surface of the shell 41 supported by the bearing platform 22 is relatively low in stability if it only relies on the abutment support of the bearing platform 22 on the bottom surface of the shell. Therefore, in one embodiment, a through hole 44 is provided on the shell 41, and a support member 23 is provided on the bearing platform 22, and the support member 23 extends into the through hole 44 to position and support the shell 41, so that the bearing platform 22 not only abuts and supports the shell 41, but also positions and limits the shell 41 by extending the support member 23 into the through hole 44, further improving the ability of the bearing platform 22 to prevent the shell 41 from being offset, that is, the ability to prevent the temperature measuring component 4 from being offset, thereby further improving the temperature measurement accuracy of the temperature measuring component 4.

[0034] Based on the above embodiment in which the support member 23 is provided on the bearing platform 22, an improved embodiment is obtained, wherein the support member 23 extends into the housing 41 through the through hole 44 to abut against and support the temperature measuring circuit board 42. The outward-turned ear piece 43 of the housing 41 is fixedly connected to the fixing platform 21 to achieve the limit of the temperature measuring component 4, and the fixing platform 21 supports both sides of the temperature measuring component 4, and combined with the support of the bearing platform 22 to the temperature measuring circuit board 42 through the support member 23, at least three-point support of the temperature measuring component 4 is achieved to improve the installation stability of the temperature measuring component 4 on the base 2. Among them, the temperature measuring circuit board 42 is arranged in the shell 41, and the temperature measuring circuit board 42 is relatively fixed to the shell 41. The supporting effect of the fixed platform 21 and the bearing platform 22 on the shell 41 can maintain the position stability of the shell 41, that is, maintain the position stability of the temperature measuring circuit board 42. When the temperature measuring component 4 is subjected to a large degree of extrusion and causes the shell 41 to deform, although the overall position of the shell 41 is still limited by the supporting parts 23 on the fixed platform 21 and the bearing platform 22, the position of the temperature measuring circuit board 42 may shift with the deformation of the shell 41. At this time, the direct supporting effect of the supporting parts 23 on the bearing platform 22 on the temperature measuring circuit board 42 can prevent the temperature measuring circuit board 42 from shifting in position with the deformation of the shell 41. In this way, even if the shell 41 is deformed, the temperature measuring circuit board 42 can still be roughly maintained at its original initial position, thereby avoiding a large shift in the temperature measurement field of view and ensuring the temperature measurement accuracy. Therefore, in this embodiment, the temperature measuring component 4 is supported and limited as a whole by the fixed platform 21, the bearing platform 22 and the support member 23, and the shell 41 together with the temperature measuring circuit board 42 are restricted to the initial position. When the temperature measuring component 4 is squeezed to a large extent and causes the shell 41 to deform, the support member 23 on the bearing platform 22 directly supports the temperature measuring circuit board 42 to prevent the position deviation of the temperature measuring circuit board 42, reduce the influence of the deformation of the shell 41, reduce or even completely avoid the position deviation of the temperature measuring circuit board 42, so that the position of the temperature measuring element 45 on the temperature measuring circuit board 42 is stable, the stability of the temperature measuring field is ensured, and the temperature measurement accuracy is ensured.

[0035] It can be understood that the outward-turned ears 43 on both sides of the shell 41 in the utility model are fixed to the fixed platform 21, and the support of the shell 41 by the supporting platform 22 forms the most basic installation limit structure for the temperature measuring component 4, that is, the temperature measuring component 4 is supported at least in three places. Of course, on this basis, a larger number of outward-turned ears 43 and / or a larger number of supporting platforms 22 can be set on the shell 41 to further improve the installation stability of the temperature measuring component 4. Figure 3 and Figure 4It is shown that the two outward-turned ears 43 in the utility model are respectively located on both sides of the shell 41, and the bearing platform 22 is located below the shell 41. In one embodiment, the three supporting points of the center of the support between the bearing platform 22 and the shell 41 and the fixing point of the two outward-turned ears 43 and the fixing platform 21 are not connected in a straight line, and they are connected in pairs to form a triangle, so as to achieve a stable support for the triangular point of the temperature measuring component 4. In the utility model, the temperature measuring circuit board 42 is arranged in the shell 41 and fixed to the shell 41. In one embodiment, an inward-turned ear 48 is arranged in the shell 41, and the temperature measuring circuit board 42 is connected to the inward-turned ear 48 with screws. When the shell 41 is deformed, the temperature measuring circuit board 42 is offset with the inward-turned ear 48; further, in one embodiment, the shell 41 includes an upper shell and a lower shell that are spliced ​​and fixedly connected to each other. In one embodiment, the fixing platform 21 is a screw column, and the outward-turned ear 43 is fixedly connected to the fixing platform 21 by screws.

[0036] Figure 2 As shown, in the utility model, a temperature measuring element 45 is provided on the temperature measuring circuit board 42, and the temperature measuring element 45 adopts an optical temperature sensing method to measure the temperature toward the side of the panel 1, that is, the temperature measuring field of the temperature measuring component 4 is toward the panel 1, so in one embodiment, a temperature measuring window 46 is provided on the side of the housing 41 facing the panel 1, and the light-sensitive portion of the temperature measuring element 45 is located on the side of the temperature measuring circuit board 42 facing the panel 1 and faces the panel 1 through the temperature measuring window 46, and after the temperature measuring element 45 is welded to the temperature measuring circuit board 42, the pin end of the temperature measuring element 45 is located on the side of the temperature measuring circuit board 42 facing the base 2, and the pin end of the temperature measuring element 45 is located on the side of the temperature measuring circuit board 42 facing the base 2, and the pin end of the temperature measuring element 45 is located on the side of the temperature measuring circuit board 42 facing the base 2. The end of the foot is easy to contact the shell 41 and cause a short circuit; and the through hole 44 for the support member 23 to pass through is located on the shell 41 facing the base 2 side, so combined with this technical feature, further improvement is made on the basis of this embodiment to obtain an improved embodiment, the through hole 44 is arranged corresponding to the pin of the temperature measuring element 45 on the temperature measuring circuit board 42, so that even if the shell 41 is deformed and the temperature measuring circuit board 42 is shifted toward the base 2, the pin of the temperature measuring element 45 will enter the through hole 44, thereby avoiding the pin of the temperature measuring element 45 from contacting the shell 41 and causing a short circuit, thereby improving safety. In this improved embodiment, the through hole 44 not only serves to allow the support member 23 to extend into to position the support shell 41, but also serves to provide a space for the pin of the temperature measuring element 45 to avoid contacting the shell 41. In an embodiment of the utility model, if the temperature measuring component 4 is used to measure the temperature of the panel 1, the temperature measuring field of view of the temperature measuring component 4 can be directed toward the panel 1. If the temperature measuring component 4 is used to measure the temperature of the cookware placed on the panel 1 through the panel 1, a light-transmitting window corresponding to the temperature measuring field of view needs to be provided on the panel 1.

[0037] The shell 41 in the present invention protects the temperature measuring circuit board 42. In one embodiment, the shell 41 is a metal shell 41, such as an aluminum shell, a copper shell, etc., which plays an electromagnetic shielding role and reduces the influence of the magnetic field generated in the electromagnetic cooking appliance on the temperature measuring accuracy of the temperature measuring component 4. However, the magnetic field can easily enter the shell 41 through the temperature measuring window 46 and the through hole 44 opened on the shell 41, thereby affecting the temperature measuring accuracy of the temperature measuring circuit board 42. Therefore, under the premise of ensuring functional requirements, the size of the temperature measuring window 46 and the through hole 44 should be minimized to enhance the electromagnetic shielding effect of the shell 41. In the present invention, the support member 23 provided on the carrier 22 only needs to be able to extend into the shell 41 through the through hole 44 and abut against the supporting temperature measuring circuit board 42. There are many options for its specific form, which can be a rod-shaped, columnar, spherical, cone-shaped or other structures. In one embodiment, Figure 2 It is shown that the support member 23 is a rod-shaped structure extending from the carrier platform 22 toward the temperature measuring circuit board 42, so that the support member 23 extends into the shell 41 in a slender state, which can not only play a supporting role between the carrier platform 22 and the temperature measuring circuit board 42, but also fully reduce its own cross-sectional area size, so that the area size of the through hole 44 arranged on the side of the shell 41 facing the base 2 can also be adaptively reduced, thereby reducing leakage magnetic field, improving the electromagnetic shielding effect, and improving the temperature measurement accuracy of the temperature measuring component 4.

[0038] The temperature measuring field of the temperature measuring component 4 faces the panel 1. Once the temperature measuring field of the temperature measuring component 4 is contaminated by pollutants such as dust, insects and oil smoke, the temperature measurement accuracy will be affected. Therefore, in one embodiment, Figure 2 and Figure 7 It is shown that a flexible and annular protective sleeve 7 is provided between the temperature measuring component 4 and the panel 1. The inner cavity of the protective sleeve 7 is through along its own central axis. The inner cavity of the protective sleeve 7 corresponds to the temperature measuring window 46 of the shell 41, that is, the protective sleeve 7 encloses the temperature measuring field area between the temperature measuring window 46 and the panel 1 in its own inner cavity, thereby preventing pollutants from entering its own inner cavity and contaminating the temperature measuring field, thereby ensuring the temperature measurement accuracy. Considering that the base 2 of the electromagnetic cooking appliance and the parts arranged on the base 2 are mostly plastic parts, they are easy to deform when squeezed, causing the distance between the panel 1 and the temperature measuring component 4 to change. Therefore, the protective sleeve 7 in this embodiment is made of a flexible material, such as rubber material, so that the protective sleeve 7 can produce adaptive deformation when squeezed. Since the deformation direction of the protective sleeve 7 is random, once the protective sleeve 7 bends and deforms toward its own inner cavity, the deformed part will enter the temperature measuring field area, affecting the temperature measurement accuracy. Figure 5An improved embodiment further improved on the basis of the present embodiment is shown, in which the housing 41 is provided with an annular protrusion 47 on the side facing the protective sleeve 7, which supports the inner side wall of the lower opening of the protective sleeve 7. The annular protrusion 47 hinders the bending deformation of the protective sleeve 7 toward its own inner cavity, thereby preventing the deformed part of the protective sleeve 7 from entering the temperature measurement field of view. It can be understood that the annular protrusion 47 can be a continuous annular structure or an intermittent annular structure, as long as it forms an annular shape as a whole and supports the inner side wall of the lower opening of the protective sleeve 7. Furthermore, the protective sleeve 7 can be set to black, so that the user can hardly perceive the protective sleeve 7 visually, thereby improving the aesthetics.

[0039] The annular protrusion 47 in the above embodiment can prevent the protective sleeve 7 from bending and deforming toward its own inner cavity when the protective sleeve 7 is slightly squeezed. When the protective sleeve 7 is squeezed to a greater extent and bends and deforms to a greater extent, the remaining parts of the protective sleeve 7 will also bend and deform to adapt to the change in the distance between the panel 1 and the temperature measuring component 4. Therefore, based on the above embodiment with the protective sleeve 7, another improved embodiment is obtained, such as Figure 7 and Figure 8 As shown, the upper part of the protective sleeve 7 is open toward the panel 1, that is, the upper part of the protective sleeve 7 is in a trumpet shape, and the inner side wall of the trumpet faces the panel 1, so that when the protective sleeve 7 is squeezed by the panel 1, the upper part of the protective sleeve 7 expands outwards to prevent the upper part of the protective sleeve 7 from bending and deforming toward its own inner cavity and entering the temperature measurement field of view; the inner wall of the lower part of the protective sleeve 7 is provided with a folded corner 71 arched outward or an annular groove. In this embodiment, the annular groove is located on the inner side wall of the protective sleeve, so it is called an inner annular groove. Figure 7 An embodiment with a folded corner 71 is shown. The folded corner 71 area or the inner ring groove area at the bottom of the protective sleeve 7 is a weak point, and both have a tendency to bulge outward. When the protective sleeve 7 is squeezed, the bottom of the protective sleeve 7 will bulge outward in the folded corner 71 area or the inner ring groove area to prevent the protective sleeve 7 from bending and deforming toward its own inner cavity and entering the temperature measurement field of view. In this improved embodiment, the folded corner 71 is an annular shape connected to form a circle along the circumference of the inner wall of the protective sleeve 7, and the inner ring groove is an annular groove connected to form a circle along the circumference of the inner wall of the protective sleeve 7. Compared with the other areas, the folded corner 71 area or the inner ring groove area are both structures that are recessed on the inside, so they have a tendency to bulge outward. Among them, in the embodiment in which the folded corner 71 is provided on the inner side wall of the lower part of the protective sleeve 7, an outer ring groove 72 can also be provided on the outer wall of the protective sleeve 7 at the corresponding folded corner 71, such as Figure 7 As shown, there is a material missing at this location, so that the lower part of the protective cover 7 is more likely to bend outward at the corner 71. It should be noted that Figure 7The embodiment in which the inner side wall of the lower part of the protective sleeve is provided with a corner 71 and the outer side wall is provided with an outer ring groove 72 correspondingly, and in the embodiment in which the inner side wall of the lower part of the protective sleeve is provided with an inner ring groove instead of a corner, the structural form of the inner ring groove is similar to Figure 7 The structure of the outer annular groove 72 provided on the outer side wall is consistent.

[0040] In the present invention, the heat generated by the electromagnetic coil 3 is transferred to the temperature measuring component 4, and the temperature measuring component 4 itself will also generate temperature rise during operation, thereby causing the temperature measuring component 4 to heat up, which is likely to cause the temperature measuring element 45 in the temperature measuring component 4 to produce temperature drift, affecting the temperature measurement accuracy. Figure 2 and Figure 3 As shown, the support platform 22 and the fixed platform 21 in the utility model jointly support the temperature measuring component 4, so that the temperature measuring component 4 is in a suspended state as a whole, which is conducive to increasing the heat dissipation area of ​​the shell 41 of the temperature measuring component 4, so that the shell 41 can dissipate heat in all directions around, and can reduce the influence of the temperature rise of the surrounding air and the temperature rise of the temperature measuring component 4 itself on the temperature measurement accuracy. The fixed platform 21 is fixedly connected to the outward-turned ear pieces 43 arranged on both sides of the shell 41, and the outward-turned ear pieces 43 are located on the outside of the shell 41, so the fixed platform 21 and the outward-turned ear pieces 43 will not block the outer wall of the shell 41 body after being fixed, that is, the heat dissipation effect of the temperature measuring component 4 will not be weakened, but the support platform 22 supports the temperature measuring component 4 by supporting the bottom surface of the shell 41. The shape of the support platform 22 and the positional relationship with the temperature measuring component 4 will affect the heat dissipation effect of the temperature measuring component 4. In one embodiment, the table surface of the carrier 22 is in close contact with the bottom surface of the shell 41 of the temperature measuring component 4, and the support stability is relatively high, but the area on the bottom surface of the shell 41 corresponding to the carrier is blocked by the carrier 22, and the heat dissipation effect of the temperature measuring component 4 is weakened. In another embodiment, a plurality of small protrusions are provided on the table surface of the carrier 22 facing the shell 41, and the shell 41 is supported by the small protrusions, so that there is a certain gap between the shell 41 and the table surface of the carrier 22 to improve heat dissipation.

[0041] In the present invention, the fixing platform 21 and the bearing platform 22 are arranged on the base 2 to support the temperature measuring component 4. The side of the base 2 away from the temperature measuring component 4 is the external space of the electromagnetic cooking device. In one embodiment, the portion on the inner bottom surface of the base 2 corresponding to the bearing platform 22 is a closed surface, and the bearing platform 22 is directly arranged on the inner bottom surface of the base 2. In another embodiment, Figure 2As shown, a notch 24 is provided on the inner bottom surface of the base 2 at a position corresponding to the bearing platform 22, and the notch 24 connects the inner space and the outer space of the base 2. The bearing platform 22 includes a table 221 and at least two supporting ribs 222 supporting the table 221. The supporting ribs 222 extend from the base 2 to the table 221. The supporting ribs 222 are arranged at intervals to form heat dissipation ports 223, and the heat dissipation ports 223 connect to the notch 24. In this way, the air around the bearing platform 22 can be connected to the external space of the electromagnetic cooking utensil through the heat dissipation ports 223 and the notch 24, and the heat around the temperature measuring component 4 can be conducted to the outside with the air, further improving the heat dissipation effect of the temperature measuring component 4, thereby improving the temperature measuring accuracy of the temperature measuring component 4. In this embodiment, since the bearing platform 22 protrudes toward the side away from the base 2, the table 221 and the supporting ribs 222 actually form a groove connecting the notch 24 and the heat dissipation ports 223, and the groove is connected to the external space of the electromagnetic cooking utensil.

[0042] In one embodiment, if Figure 3 As shown, the base 2 is also provided with a heat dissipation fan 51 and an air guide channel 52. One end of the air guide channel 52 opens toward the heat dissipation fan 51 and the other end opens toward the temperature measuring component 4. The wind generated by the heat dissipation fan 51 flows toward the temperature measuring component 4 through the air guide channel 52, thereby cooling the temperature measuring component 4, further improving the heat dissipation effect, and thus improving the temperature measurement accuracy. It can be understood that in this embodiment, the heat dissipation fan 51 can not only dissipate heat for the temperature measuring component 4, but also can be provided with a plurality of air guide channels 52 to guide the wind generated by the heat dissipation fan 51 to different components for heat dissipation. It can be understood that the electromagnetic cooking utensil itself is not a strict seal, and it has multiple gaps. Therefore, in this embodiment, the wind carrying heat flowing through the temperature measuring component 4 overflows from the gaps of the electromagnetic cooking utensil to the external space. Of course, special exhaust ports can also be provided around the base 2. Furthermore, this embodiment can be combined with the embodiment in which the space around the above-mentioned support platform 22 is connected to the external space through the heat dissipation port 223 and the gap 24 to form an improved embodiment. In this improved embodiment, the wind generated by the heat dissipation fan 51 passes through the temperature measuring component 4, which will drive the air circulation around the temperature measuring component 4, and can drive part of the air carrying heat to flow out to the external space through the heat dissipation port 223 and the gap 24. It is also possible that after the wind from the heat dissipation fan 51 takes away the air around the temperature measuring component 4, the air with lower temperature in the external space will be driven through the heat dissipation port 223 and the gap 24 to enter the internal space around the temperature measuring component 4, thereby accelerating heat dissipation and further improving the temperature measurement accuracy.

[0043] If there is no other structure blocking the temperature measuring component 4, there is no clear boundary around the temperature measuring component 4. Even if wind is transmitted to the temperature measuring component 4, the wind will spread to the surroundings when reaching the temperature measuring component 4. The impact effect of the wind on the air around the temperature measuring component 4 is average, and the flow rate of the wind slows down, and the efficiency of taking away heat is low. Therefore, based on the above embodiment with a notch and a heat dissipation port at the supporting platform, an improved embodiment is obtained, such as Figure 4 As shown, an enclosure structure 6 for enclosing a temperature measuring cavity 61 is arranged on the base 2, the temperature measuring component 4 and the supporting platform 22 are both located in the temperature measuring cavity 61, the enclosure structure 6 has an air outlet 63 and an air inlet 62 connected to the air guide channel 52, the wind of the air guide channel 52 enters the temperature measuring cavity 61 through the air inlet 62 to dissipate the heat of the temperature measuring component 4, and then the wind carrying the heat leaves the temperature measuring cavity 61 through the air outlet 63, taking the heat away from the temperature measuring cavity 61; in this way, on the one hand, the space around the temperature measuring component 4 has a clear boundary, that is, within the area of ​​the temperature measuring cavity 61, the wind derived from the air guide channel 52 has a certain influence on the air around the temperature measuring component The impact is more targeted and can blow away the air in the temperature measuring cavity 61 in a targeted manner, thereby taking away most of the heat in the air in the temperature measuring cavity 61. On the other hand, the formation of the temperature measuring cavity 61 reduces the space around the temperature measuring component 4, increases the flow rate of the wind in the temperature measuring cavity 61, thereby improving the efficiency of taking away heat. In short, the heat dissipation effect of the temperature measuring component 4 is improved, thereby improving the temperature measurement accuracy. In addition, the enclosure structure 6 separates the temperature measuring cavity 61 used to accommodate the temperature measuring component 4 from the rest of the space, which can reduce the possibility of pollutants such as dust, insects and oil smoke entering the temperature measuring cavity 61 and contaminating the temperature measuring component 4, thereby improving the temperature measurement reliability of the temperature measuring component 4. In addition, in the present improved embodiment, the space around the support platform 22 is connected with the external space through the heat dissipation port 223 and the gap 24. The flow rate of the wind flowing through the air guide channel 52 to the temperature measuring chamber 61 is still relatively high, and the air around the support platform 22 is quickly taken away. The air pressure around the support platform 22 is lower than that of the external space, and the lower temperature normal temperature air in the external space can be driven to enter the temperature measuring chamber 61 through the gap 24 and the heat dissipation port 223. The entry of this part of air also becomes cooling wind for dissipating the heat of the temperature measuring component 4, thereby increasing the air volume in the temperature measuring chamber 61, further improving the heat dissipation effect of the temperature measuring component 4, and improving the temperature measurement accuracy of the temperature measuring component 4.

[0044] It can be understood that the enclosure structure 6 described in the above embodiment is arranged on the base 2 to form a groove with an opening toward the panel 1, such as Figure 3It is shown that the temperature measuring component 4 and the fixed platform 21, the supporting platform 22 and the supporting member 23 for supporting the temperature measuring component 4 are all arranged in the temperature measuring cavity 61 formed by the enclosure structure 6. The enclosure structure 6 only surrounds the temperature measuring cavity 61 circumferentially and opens the air inlet 62 and the air outlet 63 without blocking the temperature measuring component 4 and the panel 1.
