Description

Quick temperature sensing panel integrated with coil frame and electromagnetic cooking appliance

Technical Field

The utility model relates to an electromagnetism cooking utensil technical field especially relates to an integrated quick temperature sensing panel and electromagnetism cooking utensil with coil former.

Background

Since the electromagnetic heating technology is applied to the cooking industry, temperature control is always a big problem, and the main stream induction cooker has the following two structures:

the first structure is as follows: the cooker, the microcrystal panel (about 4 mm) and the sensor component (comprising a shell, an insulating layer and a sensor are sequentially arranged from top to bottom, and the position of the sensor is arranged at the center of the coil frame). Because the micrite panel is flat structure, and the sensor subassembly hugs closely in the bottom surface of micrite panel, the characteristics of this kind of structure are that temperature sensor is too far away from between the pan, and the temperature of pan needs to be conducted the micrite panel of 4mm thick earlier, makes the micrite panel generate heat, then by micrite panel with heat conduction to sensor, consequently has the slow problem of heat conduction. In normal household cooking, the heating temperature generally required does not exceed 280 ℃, but because the temperature cannot be rapidly sensed, a pot which is thin may be burnt red, but the temperature cannot be sensed by the sensor. The results from this phenomenon are as follows: 1. potential safety hazards, severe lagging temperature sensing, can cause the oil to reach the ignition point when the amount of oil is small, causing a fire; 2. too high oil temperatures produce large quantities of aromatic hydrocarbons, which are severely carcinogenic. 3. The Chinese dishes are cooked and have poor taste.

The second structure is as follows: the hole is formed in the center of the microcrystalline glass relative to the coil rack, the temperature sensor component is in direct contact with the cooker, and the sensor component comprises a shell, an insulating layer and a sensor. The shell of the sensor is generally made of metal, when a pot is placed on the top of the sensor, the metal shell can generate heat in an alternating magnetic field (all metal can generate heat under the pot of the induction cooker, and the closer the metal is to the pot, the faster the metal is generated), so that the temperature sensing of the sensor is inaccurate; in addition, according to the requirements of safety regulations, an insulating layer is required below the shell of the sensor, and engineering plastics which can resist the temperature of about 350 ℃ are generally adopted, so that the thermal conductivity is poor. The biggest defect of the structure is that the shell can generate heat to continuously accumulate heat, and in addition, the temperature of the cookware cannot be really judged due to the heating of the shell, so that the breakthrough of the temperature sensing technology cannot be realized. At the same time, additional costs are paid for waterproofing and anti-aging.

Both of the above structures also have the following common disadvantages: in order to ensure that the sensor does not leak electricity, a shell needs to be arranged outside the sensor, so that the size of a sensor assembly is large, a special assembly position needs to be designed on a coil frame, and the heat generation efficiency of the coil frame is considered, so that the sensor assembly is usually designed in the center of the coil frame. The heat generated by electromagnetism is mainly concentrated on a circular ring with the diameter of about 90mm, so that the sensor is too far away from the high-temperature area, and the temperature cannot be accurately fed back. Almost all induction cooker manufacturers need to use their own induction cooker to perform different pot heating experiments, record temperature change curves, compare the temperature change curves with the recorded curves when users use the induction cooker, and evaluate the heating condition of the pots. However, in the actual use process, the quality change of the pan, the type change of the pan and the change of food materials are unpredictable, so that the induction cooker cannot become a mainstream cooking tool and is mainly used for boiling water, making hot pots, cooking porridge and the like. In the aspect of panel use, because accurate temperature sensing cannot be carried out, microcrystalline glass with higher temperature resistance is needed to reduce the risk of overhigh heat generation, so that the panel cost of the induction cooker is high; in addition, because the temperature of the panel is high, usually, when the coil is arranged, the coil needs to keep a certain distance from the panel so as to avoid damage to the coil caused by overhigh temperature of the panel. In addition, because the temperature of the panel is high, a certain gap is required to be kept between the coil and the panel when the coil is arranged, so that damage to the coil caused by overhigh temperature of the panel is avoided.

The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.

As shown in fig. 1 to 6, the rapid temperature sensing panel integrated with a coil frame in this embodiment includes a panel body 1, temperature sensors 2, a bottom cover 3, a coil frame 4, and a coil 5, where the panel body 1 has a plurality of mounting holes 11, the temperature sensors 2 are installed in the mounting holes 11 in a one-to-one correspondence manner, and the mounting holes 11 are filled with a heat conducting medium 6; the bottom cover 3 is arranged on the bottom surface of the panel body 1 and covers the bottom of the mounting hole 11; the bottom of the panel body 1 is provided with a plurality of abdicating holes 12, the bottoms of the abdicating holes 12 are open, and the tops of the abdicating holes 12 are closed; a connecting column 31 is arranged at the top of the bottom cover 3, a threaded hole is formed in the connecting column 31, the bottom of the threaded hole penetrates through the bottom cover 3, and the coil rack 4 is in screw connection with a plurality of threaded holes; the coil 5 is fixedly arranged at the bottom of the coil rack 4 and is wound in a ring shape or a spiral shape.

The utility model discloses a set up a plurality of mounting hole 11 on panel body 1 to install temperature sensor 2 in mounting hole 11, consequently can make the distance that greatly reduces temperature sensor 2 and panel body 1's top surface, thereby make temperature sensor 2 be close to the pan more, understandably, the distance between temperature sensor 2 and the pan is less, then temperature sensor 2 then can perceive the temperature of pan faster.

The heat-conducting medium 6 is filled in the mounting hole 11, and because the heat-conducting property of air is extremely poor, if the temperature sensor 2 is only mounted in the mounting hole 11, the temperature of the inner wall of the mounting hole 11 is high, but because the contact area between the inner wall of the mounting hole 11 and the temperature sensor 2 is small and the mounting hole 11 is filled with air, the heat of the panel body 1 is difficult to transfer to the temperature sensor 2, and the problem that the temperature sensed by the temperature sensor 2 is greatly different from the actual temperature of the pot still exists; the utility model discloses a pack heat-conducting medium 6 in mounting hole 11, heat-conducting medium 6 is all filled up with the gap between temperature sensor 2 and the mounting hole 11, thereby make and hardly exist the air between temperature sensor 2 and the mounting hole 11, when the temperature transfer of pan to panel body 1, panel body 1 is with heat transfer to heat-conducting medium 6 through the inner wall that the non runs through, heat-conducting medium 6 can be rapidly with heat transfer to temperature sensor 2, thereby make temperature sensor 2 wholly heat up, thereby realize the effect of quick temperature sensing. The mounting hole 11 in the panel body 1 may be a through hole penetrating vertically, a non-penetrating hole having an opening at the top, or a non-penetrating hole having an opening at the bottom; have the non-through hole of open-ended to the bottom, can guarantee like this that the top surface of panel body 1 still keeps complete planar structure to in-process using is convenient for clear up hot water juice, congee water on the panel body 1, also guarantees simultaneously that fluids such as hot water juice or congee water that spill on panel body 1 can not pass the inside of panel body 1 infiltration electromagnetism cooking utensil, with the waterproof nature of assurance panel body 1. And to the structure that mounting hole 11 has the non-through hole of open-ended to through-hole and top that run through from top to bottom, then heat-conducting medium 6 not only plays the gap between filling temperature sensor 2 and the mounting hole 11, still plays the effect to temperature sensor 2 encapsulation, avoids temperature sensor 2 to receive external force and damages, also seals up mounting hole 11 simultaneously, prevents in hot water juice and the congee water infiltration mounting hole 11, avoids taking place the short circuit.

In addition, because the panel body 1 is provided with the plurality of mounting holes 11, the strength of the panel body 1 is reduced, and when the panel body 1 is impacted, the position provided with the mounting holes 11 is easy to crack; according to the invention, the bottom cover 3 is adhered to the bottom surface of the panel body 1, and the bottom cover 3 covers all the mounting holes 11, so that the bottom cover 3 can play a role of reinforcing the panel body 1, when the top surface of the panel body 1 is impacted, a part of the impact force borne by the panel body 1 can be transmitted to the bottom cover 3, and the risk of cracking the panel body 1 is reduced; therefore, the panel body 1 of the present invention can have sufficient strength to withstand the impact of the cookware even though the panel body is provided with the plurality of mounting holes 11.

The temperature sensor 2 is arranged in the mounting hole 11, and the mounting hole 11 is arranged at the bottom of the panel body 1, and the panel body 1 is insulated, so that the temperature sensor 2 of the utility model can also play an insulating effect without additionally arranging a shell, and can meet the requirements of safety regulations; because need not to set up insulating shell in temperature sensor 2's outside, consequently make temperature sensor 2's volume compare in traditional electromagnetic cooking utensil's temperature sensing device volume to be little a lot, temperature sensor 2 is embedded into panel body 1's mounting hole 11 completely, only has two connecting wire to wear out, need not in the electromagnetic cooking utensil for temperature sensor 2's installation headspace, the structure is compacter, temperature sensor 2's assembly is nimble more free.

In addition, the coil 5 of the conventional electromagnetic cooker is wound in the coil rack 4, then the coil 5 and the coil rack 4 are disposed on the bottom shell of the electromagnetic cooker, and the coil 5 is supported by the support, and a certain distance is kept between the coil 5 and the coil rack 4 and the panel body 1, so that because the temperature measurement of the temperature sensor 2 of the conventional electromagnetic cooker is inaccurate and lags seriously, when the pot is overheated, heat is continuously transferred to the panel body 1, however, the temperature sensor 2 does not detect that the pot is overheated, which causes the overall temperature of the panel body 1 to continuously rise along with the pot, when the temperature of the panel body 1 reaches the preset temperature value, because the pot already exceeds the preset temperature value far, at this time, even if the electromagnetic cooking device is turned off completely or with reduced heating power, the excessive temperature of the pot still causes the temperature of the panel body 1 to continue to rise, so that the temperature of the panel body 1 is very easy to exceed the expected range, so that the current electromagnetic cooking device must leave a certain distance between the coil rack 4 and the coil 5 and the panel body 1 in order to avoid the melting of the insulating paint on the surface of the coil 5 or the coil 5 due to the excessive temperature of the panel body 1, the traditional electromagnetic cooking device utilizes the poor thermal conductivity of air to avoid the potential safety hazard caused by the melting of the panel body 1 when the temperature is too high, and even a mica sheet for heat insulation needs to be pasted on the bottom surface of the panel body 1.

The utility model discloses because install temperature sensor 2 to the mounting hole 11 in panel body 1 in, because the distance of temperature sensor 2 and the top surface of panel body 1 is very close, for example set up mounting hole 11 to have open-ended non-through hole in the bottom, and the thickness between the top of mounting hole 11 and the top surface of panel body 1 sets up to 1mm, when temperature sensor 2 installs in mounting hole 11, then the distance between temperature sensor 2 and the top surface of panel body 1 is 1mm too, so close distance can make temperature sensor 2 can detect the temperature of the top surface of panel body 1 rapidly, only need the top surface temperature of panel body 1 rise to preset temperature value can be detected by temperature sensor 2; in addition, because the pan is closely attached to the top surface of the body of the panel when cooking, the temperature of the pan is basically the same as the temperature of the top surface of the panel body 1, when the surface of the panel body 1 reaches a preset value, the temperature can be controlled by reducing the power of the electromagnetic cooking appliance, and the temperature of the pan is not greatly different from the temperature of the top surface of the panel body 1, so that the temperature of the pan cannot enable the panel body 1 to continue to be heated, the temperature of the bottom surface of the panel body 1 can be easily controlled below the preset temperature, and the temperature of the bottom surface of the panel body 1 can be effectively prevented from exceeding the preset value, therefore, the utility model discloses because the temperature of the pan and the panel body 1 can be effectively controlled, the bottom cover 3 is arranged on the bottom surface of the panel body 1 and cannot be melted in the normal use process; similarly, the bobbin 4 is not melted by overheating due to the bobbin 4 being disposed on the bottom surface of the bottom cover 3; hug closely coil former 4 in the bottom of bottom 3, can show the interval that reduces between coil 5 and the panel body 1 to can make and use the utility model discloses an electromagnetic cooking utensil can be made frivolous more.

The coil rack 4 is fixed with the threaded holes through screws, so that the bottom cover 3 and the coil rack 4 are fixed through screws, the bottom cover 3 cannot be excessively thick, if the threaded holes are directly formed in the bottom cover 3, the depth of the threaded holes can be extremely shallow, for example, only 2mm, the supporting force provided by the threaded holes which are shallow for the coil rack 4 is extremely limited, the coil 5 is wound on the coil 5, the coil 5 is usually an enameled wire made of copper and is heavy, and therefore in order to better fix the coil 5 and the coil 5 on the bottom surface of the bottom cover 3, the bottom surface of the panel body 1 is further provided with the abdicating holes 12, positioning columns on the bottom cover 3 extend into the abdicating holes 12, the depth of the threaded holes can be increased, and the coil rack 4 and the coil 5 can be firmly fixed on the bottom of the bottom cover 3 through screws. Coil former 4 and bottom 3 adopt the screw to fix can make and dismantle more easily between bottom 3 and the coil former 4, only need can take off coil former 4 with the screw back-out, and the maintenance degree of difficulty is lower.

It should be noted that when the bottom cover 3 is detached from the bottom of the panel body 1, the position of the temperature sensor 2 in the mounting hole 11 is easily affected, and even the detachment of the bottom cover 3 may cause the temperature sensor 2 to fall off; the utility model discloses a coil former 4 and bottom 3 adopt the design of components of a whole that can function independently, when coil 5 breaks down, can dismantle coil former 4 and coil 5 from bottom 3 alone and keep in repair, and bottom 3 then still is fixed in the bottom surface of panel body 1, owing to can make bottom 3 can need not to dismantle from the bottom of panel body 1 when dismantling coil former 4 and get off, not only can reduce the degree of difficulty of maintenance, also can reduce effectively because bring the inaccurate problem of temperature sensing during the maintenance.

Moreover, since the temperature sensors 2 are completely embedded in the mounting holes 11 of the panel body 1, even if the coil 5 is almost closely attached to the bottom surface of the panel body 1, the plurality of temperature sensors 2 can be provided in the panel body 1, and the coil 5 does not need to be designed to avoid the structure with respect to the temperature sensors 2, so that the temperature of each area of the pot can be accurately detected by providing the plurality of temperature sensors 2, and the coil 5 can be wound in a manner of ensuring the optimal heating efficiency.

In addition, the coil 5 is wound in a ring shape or a spiral shape, which means that the projection of the coil 5 perpendicular to the bottom surface of the panel body 1 is in a ring shape or a spiral shape, as an embodiment, the coil 5 may be wound in a ring shape or a spiral shape in a plane, as another example, the coil 5 may have a three-dimensional structure when wound, for example, a conical structure wound in a middle height and a periphery height; of course, the coil 5 is wound in a ring shape including, but not limited to, a circular ring shape, an elliptical ring shape, a polygonal ring shape, and the like.

The utility model discloses a quick temperature sensing, free assembly: the temperature sensing speed reaches more than ten times of the traditional temperature sensing speed, a special installation space is not required to be provided by the coil 5, and a plurality of sensors can be assembled at extremely low cost. Simultaneously, owing to can quick temperature sensing, let the electromagnetism stove possess the basis that realizes intelligent culinary art, reduced glass panels body 1's temperature resistant demand, can replace with borosilicate glass, fire-retardant engineering plastics, it is also possible as the panel body 1 of electromagnetism stove even with soda-lime glass in the future. These advantages will let the efficient characteristics of electromagnetism stove energy conversion come out fully to can reduce manufacturing cost by a wide margin, improve assembly efficiency, expand the range of application of electromagnetism stove. After the borosilicate glass and the soda-lime glass are tempered, the physical impact resistance strength is much higher than that of microcrystalline glass, and the safety of the induction cooker is greatly improved under the condition that the temperature resistance requirement is reduced.

Further, the bottom of the coil rack 4 is provided with a wire slot 41 or a buckle, and the coil 5 is fixed in the wire slot 41 or the buckle.
