Description

Panel and electromagnetism cooking utensil convenient to temperature sensing device wiring

Technical Field

The utility model relates to an electromagnetism cooking utensil technical field especially relates to a panel and electromagnetism cooking utensil convenient to temperature sensing device wiring.

Background

Since the electromagnetic heating technology is applied to the cooking industry, temperature control is always a big problem, and the main electromagnetic oven 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 disc). 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, temperature sensing with severe hysteresis, may cause oil to reach the ignition point when the amount of oil is small, causing a fire; 2. too high oil temperature produces large amounts of aromatic hydrocarbons, which are severely carcinogenic. 3. The Chinese dish is cooked and has poor taste.

The second structure is as follows: the hole is formed in the center position of the microcrystalline glass relative to the coil panel, 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.

The above two structures also have the following common disadvantages: in order to ensure that the sensor does not leak electricity, the outer shell is required to be arranged outside the sensor, so that the size of the sensor assembly is large, a special assembly position needs to be designed on the coil panel, and the heat generation efficiency of the coil panel is considered, so that the sensor assembly is usually required to be designed in the center of the coil panel. 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 cookers to perform different pot heating experiments, record temperature change curves, compare the temperature change curves with the recorded curves when users use the induction cookers, and evaluate the heating conditions of 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 achieved, microcrystalline glass with higher temperature resistance is needed to reduce the risk of excessive heat generation, and therefore the panel cost of the induction cooker is high.

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 4, the panel convenient for wiring of the temperature sensing device of this embodiment includes a panel body 1, a temperature sensor 2, a bottom cover 3, and a first conductive barrel 4, where the panel body 1 has a non-through hole 11 formed from bottom to top, the temperature sensor 2 is installed in the non-through hole 11, the temperature sensor 2 is tightly attached to a top surface of the non-through hole 11, and the non-through hole 11 is filled with a heat conducting medium 5; the bottom cover 3 is arranged on the bottom surface of the panel body 1, and seals the bottom opening of the non-through hole 11, the bottom cover 3 is provided with a first threading hole 31 corresponding to the wire of the temperature sensor 2 one by one, the first conductive cylinders 4 are respectively arranged in the first threading hole 31, and the wire of the temperature sensor 2 is electrically connected with the first conductive cylinders 4 in the first threading hole 31.

The utility model discloses a set up a plurality of non-through hole 11 in the bottom of panel body 1 to install temperature sensor 2 in non-through hole 11, consequently can make the distance that greatly reduces temperature sensor 2 and the top surface of panel body 1, temperature sensor 2 hugs closely the top surface setting in non-through hole 11, thereby make temperature sensor 2 be closer to the pan, understandably, the distance between temperature sensor 2 and the pan is the less, then temperature sensor 2 can perceive the temperature of pan more fast, therefore, the degree of depth of non-through hole 11 is the deeper, then the temperature sensing speed of temperature sensor 2 is more sensitive; of course, when the depth of the non-through hole 11 is deeper, the thickness between the top surface of the panel body 1 and the top of the non-through hole 11 is smaller, thereby causing the strength of the area to be reduced, and the depth of the non-through hole 11 can be set according to specific requirements.

In addition, the non-through hole 11 is filled with the heat conducting medium 5, and because the heat conducting performance of air is extremely poor, if the temperature sensor 2 is only installed in the non-through hole 11, because the contact area between the temperature sensor 2 and the bottom surface of the non-through hole 11 is small, and the rest part is filled with air, the temperature of the inner wall of the non-through hole 11 is already high, but because the contact area between the inner wall of the non-through hole 11 and the temperature sensor 2 is small, and the non-through 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 5 in non-through hole 11, heat-conducting medium 5 is all filled up with the gap between temperature sensor 2 and the non-through hole 11, thereby make almost not have the air between temperature sensor 2 and the non-through hole 11, when the temperature-transfer of pan to panel body 1, panel body 1 is through the inner wall of non-through hole 11 with heat transfer to temperature sensor 2 (temperature sensor 2 hugs closely in the top surface of non-through hole 11) and heat-conducting medium 5, heat-conducting medium 5 can be rapidly with heat transfer to temperature sensor 2, thereby make the whole intensification of temperature sensor 2, thereby realize the effect of quick temperature sensing.

Moreover, because the temperature in the non-through hole 11 is high, the heat-conducting medium 5 filled in the non-through hole 11 often works in a high-temperature environment and needs to frequently bear cold and hot impacts, even if the heat-conducting medium 5 has good temperature resistance, the problem that the heat-conducting medium 5 may age cannot be solved, and then the heat-conducting medium 5 is separated from the inner wall of the non-through hole 11, so that the risk that the temperature sensor 2 is separated from the non-through hole 11 exists, the problem that temperature sensing cannot be performed occurs, and even the pot is subjected to fire due to overhigh temperature is caused; therefore, the utility model discloses be provided with bottom 3 in each non-through hole 11 respectively, as optional embodiment, bottom 3 can be flat structure, bottom 3 seals the bottom opening of non-through hole 11, even like this heat-conducting medium 5 takes place to separate with the inner wall of non-through hole 11, temperature sensor 2 and heat-conducting medium 5 also can't fall out from non-through hole 11, temperature sensor 2 still can accurately detect the temperature of pan, the problem that temperature sensor 2 deviate from in non-through hole 11 has been avoided like this effectively, thereby greatly improved the security; in addition, the problem of short circuit caused by falling off of the temperature sensor 2 can be avoided. As one of the embodiments, the bottom cover 3 can be fixed on the bottom surface of the panel body 1 by adopting a bonding mode, and the bottom surface of the panel body 1 is far away from the pot, so that the temperature is lower than the temperature in the non-through hole 11, and in addition, the temperature sensing speed of the utility model is sensitive, so that the temperature control hysteresis is basically avoided, the temperature of the panel body 1 can be effectively ensured not to be too high, and the problem of cold and hot impact is basically avoided on the bottom surface of the panel body 1, so that the bottom cover 3 is fixed on the bottom surface of the panel body 1 by adopting a temperature-resistant adhesive without the risk of falling off; of course, the bottom cover 3 may be fixed to the bottom of the panel body 1 by other methods, for example, a support column may be provided on the coil disc to support the bottom cover 3, a snap ring may be provided on the top of the bottom cover 3, and the snap ring may be interference-fitted with the non-through hole 11, and the fixing method between the bottom cover 3 and the panel body 1 is merely described here, and the fixing method between the bottom cover 3 and the panel body 1 is not limited.

After the temperature sensor 2 is installed in the non-through hole 11 in the panel body 1, the wire of the temperature sensor 2 penetrates out of the threading hole of the bottom cover 3 and then needs to be electrically connected with the wiring terminal 6, the temperature sensor 2 is connected to the circuit board of the electromagnetic cooking appliance through the wiring terminal 6, because the temperature sensor 2 is installed in the non-through hole 11 of the panel body 1 and is sealed by the bottom cover 3, at this time, when the wire of the temperature sensor 2 is electrically connected with the wire of the wiring terminal 6, the panel body 1 needs to be carried for operation, for example, the temperature sensor 2 is connected with the wiring terminal 6 through welding, in order to facilitate the operation, a jig is usually needed to be matched for welding, if the jig is placed on the bottom cover 3, the jig easily scratches the bottom cover 3, the product quality is affected, and if the jig is not used for welding, certain operation difficulty exists; in addition, because the lead of the temperature sensor 2 needs to be adjusted in the welding process so as to be in butt joint with the lead of the connecting terminal 6 and then be welded, in the process of adjusting the lead of the temperature sensor 2, the temperature sensor 2 is subjected to a certain force and is easy to move in the non-through hole 11, so the welding can be performed after the heat-conducting medium 5 in the non-through hole 11 is cured, if the heat-conducting medium 5 is made of a temperature-resistant glue, such as a silicone glue, the curing time needs about 8 hours, and thus a large amount of semi-finished products are in a state of waiting for curing in batch production, and the production efficiency is seriously affected; if the heat-conducting medium 5 is heat-conducting silicone grease, the heat-conducting silicone grease is not solidified, so that it is extremely difficult to ensure that the temperature sensor 2 does not move in the welding process; as one of them embodiment, the utility model discloses set up the through wires hole with temperature sensor 2's wire one-to-one on bottom 3, temperature sensor 2 has two wires, bottom 3 lid is opened and is equipped with the through wires hole that corresponds, set up first electrically conductive section of thick bamboo 4 in every through wires hole respectively, can be through interference fit between first electrically conductive section of thick bamboo 4 and the through wires hole, mode such as bonding is fixed, temperature sensor 2's wire can penetrate in the first electrically conductive section of thick bamboo 4 that corresponds and carry out the electricity with first electrically conductive section of thick bamboo 4 and be connected, binding post 6's wire also can insert in first electrically conductive section of thick bamboo 4, carry out the electricity with temperature sensor 2's wire together and be connected, the setting need not to adjust temperature sensor 2's wire like this, make whole connection process simpler, high efficiency, and need not to use the tool. In addition, because the side walls of the first conductive cylinder 4 are all conductive, the contact area between the conducting wire of the temperature sensor 2 and the first conductive cylinder 4 can be larger, and the problem of poor contact is not easy to occur.

Furthermore, the utility model discloses a set up non-through hole 11 on panel body 1, can guarantee like this that panel body 1's top surface still keeps complete planar structure to be convenient for clear up soup, congee water etc. on panel body 1 at the in-process that uses, also guarantee simultaneously that fluids such as soup or congee water that spill on panel body 1 can not pass panel body 1 infiltration electromagnetism cooking utensil's inside, in order to guarantee panel body 1's waterproof nature.

The temperature sensor 2 is arranged in the non-through hole 11, and the non-through 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 role without additionally arranging a shell, and can meet the requirement 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 to be littleer a lot, temperature sensor 2 almost imbeds in panel body 1's non-through hole 11 completely, only has two connecting wire to wear out, need not in the electromagnetic cooking utensil for temperature sensor 2's installation reserved space, and the structure is compacter, and temperature sensor 2's assembly is nimble more freely.

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 panel, 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 high characteristics of electromagnetism stove energy conversion efficiency come out fully to can reduce manufacturing cost, assembly efficiency by a wide margin, 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 temperature sensor also comprises a wiring terminal 6, and a lead of the wiring terminal 6 is electrically connected with the first conductive cylinder 4 so as to be electrically connected with the temperature sensor 2.

First conductive cylinder 4 can play the effect of intermediate junction, and temperature sensor 2's wire and binding post 6's wire are connected with first conductive cylinder 4 electricity respectively, realize temperature sensor 2 and binding post 6's electricity through first conductive cylinder 4 and are connected to can avoid binding post 6 direct and temperature sensor 2's wire to lead to temperature sensor 2 to take place to remove in non-through hole 11 when carrying out the electricity connection like this.
