Description

Quick temperature sensing panel with coil panel and electromagnetic cooking utensil using same

Technical Field

The invention relates to the technical field of electromagnetic cooking appliances, in particular to a quick temperature sensing panel with a coil panel and an electromagnetic cooking appliance using the quick temperature sensing panel.

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 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.

Both of the above 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 to accurately feed back the temperature. 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 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 panel temperature is high, when the coil is arranged, a certain gap is required to be kept between the coil and the panel so as to avoid damage to the coil caused by the overhigh panel temperature.

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 5, the rapid temperature sensing panel with a coil panel of this embodiment includes a panel body 1, a temperature sensor 2, a bottom cover 3, and a coil 4, where the panel body 1 has a plurality of mounting holes 11, the temperature sensors 2 are a plurality of, 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 5; 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 coil 4 is fixedly arranged at the bottom of the bottom cover 3 and is wound in a ring shape or a spiral shape.

According to the invention, the plurality of mounting holes 11 are formed in the panel body 1, and the temperature sensor 2 is mounted in the mounting holes 11, so that the distance between the temperature sensor 2 and the top surface of the panel body 1 can be greatly reduced, and the temperature sensor 2 is closer to a pot, and understandably, the temperature of the pot can be sensed by the temperature sensor 2 more quickly when the distance between the temperature sensor 2 and the pot is smaller.

The heat-conducting medium 5 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; according to the invention, the mounting hole 11 is filled with the heat-conducting medium 5, and the heat-conducting medium 5 completely fills the gap between the temperature sensor 2 and the mounting hole 11, so that air hardly exists between the temperature sensor 2 and the mounting hole 11, when the temperature of the cooker is transferred to the panel body 1, the panel body 1 transfers heat to the heat-conducting medium 5 through the non-penetrating inner wall, and the heat-conducting medium 5 can rapidly transfer heat to the temperature sensor 2, so that the temperature of the temperature sensor 2 is integrally raised, and the effect of rapid temperature sensing is realized. 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 in using is convenient for clear up soup, congee water on the panel body 1, also guarantees simultaneously that fluid such as soup or congee water that spill on the panel body 1 can not pass the inside that panel body 1 permeates electromagnetic cooking utensil, with the waterproof nature of guaranteeing 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 5 not only plays the gap between filling temperature sensor 2 and the mounting hole 11, still plays the effect to the encapsulation of temperature sensor 2, 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 formed in the bottom of the panel body 1, and the panel body 1 is insulated, so that the temperature sensor 2 can also have 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 4 of the conventional electromagnetic cooker is wound in the coil 4 rack, then the coil 4 and the coil 4 rack are arranged on the bottom shell of the electromagnetic cooker, and the coil 4 is supported by the support, and a certain distance is kept between the coil 4 and the coil 4 rack 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, the heat is continuously transferred to the panel body 1, but the temperature sensor 2 does not detect that the pot is overheated, the overall temperature of the panel body 1 continuously rises along with the pot, when the temperature of the panel body 1 reaches the preset temperature value, because the pot is far beyond the preset temperature value, at this time, even if the electromagnetic cooker is turned off completely even if the heating power is reduced, the excessive temperature of pan still can make the temperature of panel body 1 continue to rise to make the temperature of panel body 1 exceed the anticipated scope very easily, so current electromagnetic cooking utensil avoids making the insulating varnish on coil 4 support or coil 4 surface melt because the excessive temperature of panel body 1, so traditional electromagnetic cooking utensil must leave certain interval between coil 4 frame and coil 4 and the panel body 1, melt it and arouse the potential safety hazard when utilizing the relatively poor heat conductivity of air to avoid the excessive temperature of panel body 1, even still need paste the mica sheet that is used for thermal-insulated in the bottom surface of panel body 1.

According to the invention, because the temperature sensor 2 is installed in the installation hole 11 in the panel body 1, and because the distance between the temperature sensor 2 and the top surface of the panel body 1 is extremely close, the installation hole 11 can be a non-through hole with an opening at the top, a non-through hole with an opening at the bottom, or a through hole penetrating up and down, taking the example that the installation hole 11 is set as the non-through hole with an opening at the bottom, the thickness between the top of the installation hole 11 and the top surface of the panel body 1 is set to be 1mm, when the temperature sensor 2 is installed in the installation hole 11, the distance between the temperature sensor 2 and the top surface of the panel body 1 is also 1mm, and the close distance can enable the temperature sensor 2 to rapidly detect the temperature of the top surface of the panel body 1, and the temperature of the top surface of the panel body 1 can be detected by the temperature sensor 2 only when the temperature of the top surface of the panel body 1 rises to a preset temperature value; in addition, because the cooker is tightly attached to the top surface of the panel body when cooking, the temperature of the cooker is basically the same as that 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, the temperature of the cooker is not greatly different from the temperature of the top surface of the panel body 1, so the temperature of the cooker can not cause the panel body 1 to continuously rise, so that the bottom surface temperature of the panel body 1 can be easily controlled below the preset temperature, thereby effectively preventing the bottom surface temperature of the panel body 1 from exceeding the preset value, therefore, the invention can effectively control the temperature of the cooker and the panel body 1, therefore, the bottom cover 3 is arranged on the bottom surface of the panel body 1 and can not be melted in the normal use process, so that the coil 4 can be arranged in the bottom wire slot 31 or the buckle of the bottom cover 3; the coil 4 is arranged in the bottom wire slot 31 or the buckle of the bottom cover 3, so that the distance between the coil 4 and the panel body 1 can be obviously reduced, and the electromagnetic cooking appliance can be made thinner; moreover, since the temperature sensors 2 are completely embedded in the non-through holes of the panel body 1, even if the coil 4 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 4 does not need to have an avoidance structure for 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 4 can be wound in a manner of ensuring the optimal heating efficiency.

In addition, the coil 4 is wound in a ring shape or a spiral shape, which means that the projection of the coil 4 perpendicular to the bottom surface of the panel body 1 is in a ring shape or a spiral shape, as an embodiment, the coil 4 may be wound in a ring shape or a spiral shape in a plane, as another example, the coil 4 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 4 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 invention realizes rapid temperature sensing and 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 4, 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 bottom cover 3 is provided with a wire slot 31 or a buckle, and the coil 4 is fixed in the wire slot 31 or the buckle.

By arranging the wire slots 31 or the buckles, the coils 4 can be limited, so that the coils 4 can be wound into a ring shape or a spiral shape, each coil 4 can be wound according to the same shape, and the quality consistency of products is higher; in addition, the wire slot 31 or the buckle can keep the coil 4, so that the coil 4 is not easy to deform under the action of external force, and the influence on the heating efficiency due to the change of a magnetic field caused by the deformation of the coil 4 is avoided; moreover, wire casing 31 and buckle can also make and can alternate segregation between each circle, avoid the insulating varnish on coil 4 surface to appear damaged and the short circuit appears.

Further, the coil 4 is fixed to the bottom cover 3 by bonding.

Set up like this and can conveniently fix coil 4, coil 4 both can bond in the bottom surface of bottom 3 through the temperature resistant glue, also can bond in wire casing 31 or buckle, prevents that coil 4 from falling out owing to under the effect of gravity.

Further, the bottom cover 3 is provided with threading holes 32 corresponding to the wires of the temperature sensor 2 one by one, and each threading hole 32 is staggered with the coil 4.

Further, the temperature sensor also comprises a conductive cylinder 6, the conductive cylinder 6 is fixed in the threading hole 32, and a lead of the temperature sensor 2 is electrically connected with the conductive cylinder 6 in the corresponding threading hole 32.

After the temperature sensor 2 is installed in the installation hole 11 of the panel body 1, the wire of the temperature sensor 2 penetrates out of the threading hole 32 of the bottom cover 3, and then needs to be electrically connected with the wiring terminal, the temperature sensor 2 is connected to the circuit board of the electromagnetic cooking appliance through the wiring terminal, for example, the temperature sensor 2 is connected with the wiring terminal through welding, because the wire of the temperature sensor 2 needs to be adjusted in the welding process so as to be convenient for butting and welding the wire of the temperature sensor 2 and the wire of the wiring terminal, in the process of adjusting the wire of the temperature sensor 2, the temperature sensor 2 can be subjected to a certain force and is easy to move in the installation hole 11, therefore, the welding can be carried out after the heat-conducting medium 5 in the installation hole 11 is solidified, if the heat-conducting medium 5 is made of temperature-resistant glue, such as silicone glue, the curing time is about 8 hours, so that a large amount of semi-finished products are in a state of waiting for curing during mass production, and the production efficiency is seriously influenced; 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 embodiment, the bottom cover 3 is provided with the threading holes 32 corresponding to the wires of the temperature sensor 2 one by one, the temperature sensor 2 is provided with two wires, the bottom cover 3 is covered with the corresponding threading holes 32, each threading hole 32 is internally provided with the conductive cylinder 6, the conductive cylinders 6 and the threading holes 32 can be fixed in a way of interference fit, bonding and the like, the wires of the temperature sensor 2 can penetrate into the corresponding conductive cylinders 6 and are electrically connected with the conductive cylinders 6, the wires of the wiring terminals can also be inserted into the conductive cylinders 6 and are electrically connected with the wires of the temperature sensor 2, and the wires of the temperature sensor 2 do not need to be adjusted, so that the whole connection process is simpler, the efficiency is higher, and no jig is needed. In addition, because the side walls of the conductive cylinder 6 are all conductive, the contact area between the wires of the temperature sensor 2 and the conductive cylinder 6 can be larger, and the problem of poor contact is not easy to occur.

Further, the temperature sensor device further comprises an abutting piece 7, wherein the abutting piece 7 is arranged between the temperature sensor 2 and the top surface of the bottom cover 3, and the abutting piece 7 abuts against the bottom of the temperature sensor 2.
