The most widely used electromagnetic cooking appliances in the prior art include induction cookers and electromagnetic cookers.

Electromagnetic cooking utensil mainly includes among the prior art: the coil panel, the control panel and the temperature measuring device are positioned in a space enclosed by the bottom shell and the panel. Wherein temperature measuring device's mounting structure specifically does: the bottom laminating of panel is installed the mount pad, is equipped with the mounting hole in the mount pad and is used for inserting fixed mounting temperature probe, still is equipped with heat conduction silicone grease material layer between the bottom surface of mount pad top surface and panel. When placing the pan on the electromagnetic cooking utensil, the coil panel heats the pan, can transmit the panel region of giving self contact after the pan temperature risees, and the panel is heated the back and gives heat conduction silicone grease with the temperature transfer again, and heat conduction silicone grease gives the mount pad with the temperature transfer then, and final temperature mount pad gives temperature probe with the temperature transfer.

Among the present electromagnetism cooking utensil product, this kind of temperature detects structure has obvious technical defect:

1. in the existing electromagnetic cooking utensil product, a temperature probe is used for detecting temperature data transmitted by a panel and indirectly predicting the temperature of a pot through the temperature data so as to judge whether the pot is dry-burned or not; when the pan appeared dry combustion method, the pan appeared warping very easily, and the bottom that leads to the pan is unsmooth, and when the bottom of pan and panel can't maintain the state of high laminating, even the pan appeared dry combustion method this moment, the temperature of panel also probably appeared rising the obscure condition, temperature probe just can't be quick the accurate temperature change that detects the pan of the temperature information through the panel this moment to can't reach the technical purpose who prevents the pan dry combustion method.

Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

As shown in fig. 1 to 10, a temperature probe 100 includes: a housing 110, a temperature sensor 120 and a top pressure mounting structure 116; the housing 110 is provided with at least one installation cavity 111 with a downward opening; the temperature sensor 120 is installed in the installation cavity 111, and the temperature sensor 120 is used for detecting the temperature of the shell 110; the top pressure mounting structure 116 is mounted in the mounting cavity 111 in a limited manner, and is used for mounting the temperature sensor 120 on the top surface of the mounting cavity 111 in a tight fit manner.

The top pressure mounting structure 116 may be an elastic supporting member made of an elastic material such as heat conductive silicone, or a rigid supporting rod made of a hard material with a supporting function, and the temperature sensor 120 can be mounted on the top surface of the mounting cavity 111 by using its own pressing force.

In order to ensure that the top pressure mounting structure 116 can more stably mount the temperature sensor 120 in the mounting cavity 111, when the top pressure mounting structure 116 is a top pressure bolt 132 or a fastening member 133 as shown in fig. 2 and 3, a hollow gap may exist between the top pressure mounting structure 116 and the mounting cavity 111, and a filling material may be filled into the hollow gap through a glue filling operation to form a filling structure 137; in order to protect the temperature sensor 120 from being damaged due to rigid contact with the top mounting structure 116, a pad may be added at a position where the top mounting structure 116 contacts the temperature sensor 120, and the pad may be made of a material such as rubber or soft plastic.

As shown in fig. 1, in some embodiments, the top pressure mounting structure 116 is a filling fixture 131 filled in the mounting cavity 111; the filling fixture 131 presses the temperature sensor 120 upward so that the temperature sensor 120 is closely attached to the top surface of the mounting cavity 111. Specifically, the filling fixture 131 may be an elastic support made of an elastic material, and the filling fixture 131 is inserted into the mounting cavity 111 by external pressure and is fixedly mounted in the mounting cavity 111 by interference fit with the mounting cavity 111; the filling fixture 131 may also be a solid structure formed by filling and curing a filling material in the mounting cavity 111. In this embodiment, both the filling material and the filling structure may be made of a filling material, so that the filling material is both the press-mounting structure and the filling structure. Similarly, when the temperature sensor is installed in the installation cavity, the pre-positioning element 139 may be used to press the temperature sensor 120 against the top surface of the installation cavity 111 under the action of external force, and the glue is filled into the installation cavity 111 to finally form the stable filling structure 137, so that after the external force on the pre-positioning element 139 is removed, the stability of the internal structure of the temperature probe structure can still be ensured. The filling structure 137 can completely control and exhaust the air in the installation cavity 111, so that the interference of the air on temperature detection is eliminated, and the detection accuracy of the temperature sensor is improved.

Specifically, or as shown in fig. 6, the cross section of the limiting portion 112 is an inverted trapezoid; the inclined plane arranged at the bottom of the limiting part 112 is installed above the limiting through hole in a limiting way.

Alternatively, as shown in fig. 1 to 5, the cross section of the limiting portion 112 is a regular trapezoid; the horizontal plane arranged at the bottom of the limiting part 112 is closely attached to the top surface of the panel 200.

When the cross section of the housing 110 is T-shaped, the limit portion 112 and the panel 200 can be fixed only by fitting and mounting the limit portion and the panel 200, specifically, the limit portion 112 and the panel 200 are fixed by bonding with a bonding layer made of a bonding material; or can be connected and fixed by a connecting piece such as a screw. The contact surface of the shell 110 and the top surface of the panel 200 is provided with an elastic sealing ring 115; the elastic sealing ring 115 is used to seal the gap between the housing 110 and the panel 200, and also can prevent the panel 200 from being damaged due to the rigid contact between the housing 110 and the panel 200. Specifically, the elastic sealing ring 115 may be disposed between the limiting portion 112 and the panel 200, or between the locking member 114 and the panel 200; the elastic sealing ring 115 is made of an elastic material such as elastic rubber or elastic plastic material.

When the cross section of the housing 110 is i-shaped, the limiting portion 112, the locking member 114 and the panel 200 may be attached to each other to fix the three, specifically, as shown in fig. 7, in some embodiments, the limiting portion 112 is disposed at the lower end of the connecting portion 113 and extends to the periphery of the connecting portion 113; a locking member 114 is further disposed at the upper end of the connecting portion 113, and the locking member 114 is sleeved outside the connecting portion 113, so that the cross-sectional shape of the housing 110 is i-shaped; the retaining member 114 and the position-limiting portion 112 clamp and fix the panel 200.

As shown in fig. 5, in some embodiments, when the position-limiting portion 112 is located at the upper end of the connecting portion 113, the locking member 114 may also be disposed at the lower end of the connecting portion 113, so that the cross-sectional shape of the housing 110 is an i-shape, and the locking member 114 and the position-limiting portion 112 may also clamp and fix the panel 200.

As shown in fig. 1, fig. 2, fig. 4, fig. 5, fig. 6, and fig. 7, a blocking piece 140 is detachably blocked and mounted at the bottom of the mounting cavity 111, and a top pressure mounting structure 116 is arranged in the mounting cavity 111; the plugging member 140 presses and mounts the abutting mounting structure 116 in the mounting cavity 111, and the abutting mounting structure 116 tightly mounts the temperature sensor 120 on the top surface of the mounting cavity 111.

As shown in fig. 1, the locking member 114 and the abutting mounting structure 116 may be a split structure; as shown in fig. 2, the locking member 114 and the press-fitting structure 116 may be an integral structure; as shown in fig. 5, the retaining member 114 and the blocking member 140 may be a unitary structure; as shown in fig. 7, the locking member 114 and the blocking member 140 can be two separate structures. Similarly, the limiting portion 112 and the connecting portion 113 may be separate structures or may be an integrated structure; as shown in fig. 1 to 7, the mounting cavity 111 may be provided only in the connecting portion 113; as shown in fig. 8, the mounting cavity 111 may be disposed in both the limiting portion 112 and the connecting portion 113, and similarly, the mounting cavity 111 may be disposed only in the limiting portion 112, and the selection of the position of the mounting cavity 111 and the abutting mounting structure 116 in the mounting cavity 111 is flexibly adjusted by those skilled in the art according to the shape of the housing 110, i.e., the functional requirements.

The temperature sensor 120 includes a temperature sensing body and a power supply wire 121 connected to the temperature sensing body; an insulating material is disposed in the mounting cavity 111, and the insulating material is used for separating the power supply lead 121 from the mounting cavity 111. The temperature sensor 120 is an electrical component, although the type and style of the electrical component with temperature detection in the prior art are various, all the electrical components are provided with temperature sensing bodies for contacting with other objects for sensing temperature, and the temperature sensing bodies are also connected with power supply leads 121; when the temperature sensor 120 and the installation cavity 111 are tightly attached to each other, the power supply lead 121 is also easily contacted with the housing 110, and when the temperature of the housing 110 is high, the power supply lead 121 is directly damaged, so that the temperature sensor 120 cannot normally work.

Specifically, the insulating material may be wrapped outside the power supply lead 121, or may be laid at a position where the power supply lead 121 may contact the mounting cavity 111, as long as the power supply lead 121 is separated from the mounting cavity 111, and a person skilled in the art may set the specific setting position and shape flexibly according to actual conditions.

Specifically, the thickness dimension range of the limiting portion 112 is as follows: 0.5mm-8 mm; the thickness dimension range of the top wall of the mounting cavity 111 is as follows: 0.1mm-3 mm. With the horizontal thickness dimension of spacing portion 112 and the thickness dimension setting of the roof of installation cavity 111 are in above-mentioned within range, can make spacing portion 112 thickness ratio the thickness of the roof of installation cavity 111 is big, makes casing 110 has stable bearing structure's basis to the pan, lets the temperature that casing 110 contact was transmitted can be preferentially transmitted to in the extension through the roof of installation cavity 111 fast to make the temperature of pan can transmit to in installation cavity 111 fast accurate real-time, thereby further improved precision and real-time when temperature probe 100 detects the temperature.

More preferably, temperature sensor 120 direct with the installation is hugged closely to the top surface of installation cavity 111, can avoid lead temperature probe 100 with leave the air gap between the top surface of installation cavity 111 and influence the heat conduction precision, and then let temperature probe 100 can be more quick accurate with the temperature detection collection of pan.

As shown in fig. 4, 5, 6, 7 and 11, a panel assembly includes a panel 200 and a temperature probe 100 as described above; the panel 200 is provided with at least three temperature sensing through holes, and the three temperature probes 100 are respectively arranged in the temperature sensing through holes;

Preferably, a limiting installation part is further arranged below the temperature probe 100 of the panel assembly, and the limiting installation part is provided with a limiting hole; the limiting installation piece is attached to the bottom surface of the panel 200 in a limiting mode; the connecting part 113 penetrates through the limiting hole, and the temperature probe 100 and the panel 200 are fixedly installed by the limiting installation part.

The specific implementation of the limiting installation part is various, so that the temperature probe 100 cannot rotate relative to the panel 200 under the action of external force. It is specific, for example spacing installed part can be lock nut, can the outside external screw thread that sets up of lumen portion, lock nut passes through the external screw thread is screwed up the top of lumen portion, lock nut with the bottom of panel 200 is hugged closely and is makeed temperature probe 100 can fixed mounting under the laminating pressure effect on the panel 200, temperature probe 100 can't remove on vertical direction, also can't rotate on the horizontal direction, thereby has guaranteed temperature probe 100 and the more stable contact of pan.

For another example, the limit mounting member may be a limit mounting plate 210, and the limit mounting member is formed by splicing a plurality of plates. As shown in fig. 12 and 13, the limiting mounting plate 210 needs to provide a corresponding number of limiting holes at corresponding positions according to the number and positions of the temperature probes 100 mounted on the panel 200; the limiting mounting plate 210 may be a fork-shaped structural plate formed integrally, or may be an annular structure, and in this embodiment, if the integrally formed fork-shaped structural plate is adopted, the limiting mounting plate 210 is complicated in the production process or the waste of trimming scraps is too much, so that the production cost is affected; in this embodiment, the limiting mounting plate 210 is formed by splicing a plurality of strip-shaped plates, a clamping groove 211 and a clamping protrusion 212 which can be clamped and positioned on a horizontal plane are arranged on each strip-shaped plate, and each strip-shaped plate can be fixedly attached to the bottom surface of the panel 200 by an adhesive or a screw; the connecting portion 113 of the temperature probe 100 is installed in the limiting hole in a limiting manner and fixed by the limiting hole, so that the temperature probe 100 cannot horizontally rotate.

In the description of the present invention, it is to be understood that the orientation or positional relationship indicated by the orientation words such as "front, rear, upper, lower, left, right", "lateral, vertical, horizontal" and "top, bottom", etc. are usually based on the orientation or positional relationship shown in the drawings, and are only for convenience of description and simplicity of description, and in the case of not making a reverse description, these orientation words do not indicate and imply that the device or element being referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore, should not be considered as limiting the scope of the present invention; the terms "inner and outer" refer to the inner and outer relative to the profile of the respective component itself.

Spatially relative terms, such as "above … …," "above … …," "above … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial relationship to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if a device in the figures is turned over, devices described as "above" or "on" other devices or configurations would then be oriented "below" or "under" the other devices or configurations. Thus, the exemplary term "above … …" can include both an orientation of "above … …" and "below … …". The device may be otherwise variously oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without inventive effort, which would fall within the scope of the present invention.
