Description

Impact-resistant quick temperature sensing panel

Technical Field

The utility model relates to the technical field of electromagnetic cooking appliances, in particular to an impact-resistant rapid 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 induction cooker structure has the following two types:

the first structure: the cooker and the microcrystal panel (about 4 mm) are arranged from top to bottom in sequence, and the sensor component (comprising a shell, an insulating layer and a sensor, wherein the position of the sensor is arranged at the center of the coil panel). Because the microcrystalline panel is the platy structure, sensor subassembly hugs closely in the bottom surface of microcrystalline panel, and the characteristics of this kind of structure are that the distance is too far away between temperature sensor and the pan, and the temperature of pan needs to be conducted to 4mm thick microcrystalline panel earlier, makes microcrystalline panel generate heat, then is conducted the sensor with the heat by microcrystalline panel again, therefore has the problem that the heat conduction is too slow. Normal home cooking generally requires a heating temperature of no more than 280 degrees celsius, but because of the inability to quickly sense temperature, a thinner pan may already be burned, but the sensor does not sense temperature. The results of this phenomenon are as follows: 1. potential safety hazards, severely lagged temperature control, and possibility of causing fire disaster when oil quantity is small can lead the oil to reach the ignition point; 2. excessive oil temperatures produce large amounts of aromatic hydrocarbons and are severely carcinogenic. 3. Chinese dishes are relatively poor in taste.

The second structure: and a hole is formed in the central position of the glass ceramics relative to the coil panel, so that the temperature sensor component is directly contacted with the pot, and the sensor component comprises a shell, an insulating layer and a sensor. The shell of the sensor is generally made of metal, and when a cooker is placed on the top of the sensor, the metal shell can generate heat in the alternating magnetic field (all metals can generate heat below the cooker of the electromagnetic oven, and the closer to the cooker, the faster the heat is generated), so that the temperature of the sensor is inaccurate; in addition, according to the requirements of safety regulations, an insulating layer is needed below the shell of the sensor, engineering plastics with temperature resistance of about 350 ℃ are generally adopted, and the thermal conductivity is poor. The greatest disadvantage of the structure is that the shell can generate heat to continuously accumulate heat, and in addition, the shell generates heat to cause that the temperature of the cooker cannot be truly judged, so that breakthrough in the temperature sensing technology cannot be realized. Meanwhile, the waterproof and anti-aging effects also need to pay additional cost.

The two structures have the following common defects: in order to ensure that the sensor does not leak electricity, a housing needs to be arranged outside the sensor, so that the sensor assembly is large in size, a special assembly position needs to be designed on the coil panel, and the coil panel is usually designed at the center of the coil panel in consideration of the heating efficiency of the coil panel. The heat generated by electromagnetic heating is mainly concentrated on a circular ring with the diameter of about 90mm, so that the sensor is far away from a high-temperature area and cannot accurately feed back the temperature. Almost all induction cooker manufacturers need to use the induction cooker to carry out different cooker heating experiments, record temperature change curves, compare the temperature change curves with the recorded curves when the induction cooker manufacturers use the induction cooker, and evaluate the heating condition of the cooker. However, in the actual use process, the quality change, the type change and the food material change of the cookware are unpredictable, so that the induction cooker cannot become a main cooking tool and is mainly used for boiling water, chafing dish, porridge and the like. In the aspect of panel use, because the temperature cannot be sensed accurately, microcrystalline glass with higher temperature resistance is needed to reduce the risk of excessive heating, and therefore the panel cost of the induction cooker is high.

The embodiment discloses an impact-resistant rapid temperature sensing panel, which is shown in figures 1-7 and comprises a panel body 1, a wear-resistant heat conducting piece 2 and a temperature sensor 3; the top surface of the panel body 1 is provided with a plurality of grooves 11, and the bottom surface of the grooves 11 is provided with containing holes 12 which penetrate up and down; the wear-resistant heat conducting plate 2 is respectively fixed in the groove 11, the top surface of the wear-resistant heat conducting plate 2 is higher than the top surface of the panel body 1, the wear-resistant heat conducting plate 2 is provided with a supporting part 21 supported on the top surface of the panel body 1 and a limiting part 22 inserted into the groove 11, and the bottom surface of the limiting part 22 is suspended above the bottom surface of the groove 11; the temperature sensors 3 are respectively fixed in the accommodating holes 12, and the tops of the temperature sensors 3 are propped against the wear-resistant heat conducting plate 2.

According to the utility model, the groove 11 is formed in the top surface of the panel body 1, the wear-resistant heat-conducting plate 2 is fixed in the groove 11, the wear-resistant heat-conducting plate 2 is supported on the top surface of the panel body 1 through the supporting part 21, the bottom of the wear-resistant heat-conducting plate 2 is not contacted with the bottom of the groove 11, so that the stress point of the panel body 1 is positioned on the top surface of the panel body 1, the bottom surface of the groove 11 is not stressed, when the cooker is placed on the quick temperature-sensitive panel, the cooker is pressed on the wear-resistant heat-conducting plate 2, and then the gravity of the cooker is transferred to the top surface of the panel body 1 through the wear-resistant heat-conducting plate 2.

The temperature sensor 3 passes through the panel body 1 and is propped against the wear-resistant temperature-conducting sheet 2, so that the distance between the temperature sensor 3 and the cooker is greatly reduced, the temperature of the cooker can be transferred to the temperature sensor 3 more quickly, and the temperature sensing speed can be effectively improved; during installation, the temperature sensor 3 can penetrate upwards from the bottom surface of the panel body 1 through the accommodating hole 12, and the temperature sensor 3 is propped against the wear-resistant heat conducting plate 2, however, the temperature sensor 3 and the wear-resistant heat conducting plate 2 can be fixed by bonding through the temperature-resistant glue 4, then the wear-resistant heat conducting plate 2 and the temperature sensor 3 are fixed into the groove 11 together, and the lead wire of the temperature sensor 3 passes through the accommodating hole 12 from top to bottom, so that the temperature sensor 3 is electrically connected with other electrical components of the electromagnetic cooking appliance, and the specific installation method is not limited herein; as one of the embodiments, the wear-resistant heat-conducting plate 2 can be made of metal materials, such as stainless steel, aluminum alloy or copper alloy, which not only has higher heat-conducting efficiency, but also has higher strength, better ductility and wear resistance, so that the wear-resistant heat-conducting plate 2 can protect the temperature sensor 3 only by being arranged to be thinner, and is not easy to wear due to impact and friction of a cooker in the long-term use process, and has longer service life; of course, the wear-resistant heat-conducting plate 2 can also be made of engineering plastics, such as PEEK materials, and also has good wear resistance. Because wear-resisting heat conduction piece 2 has supporting part 21, therefore the top surface of wear-resisting heat conduction piece 2 is higher than the top surface of panel body 1, when the pan was placed on quick temperature sensing panel, wear-resisting heat conduction piece 2 can support the pan for pan and panel body 1 do not direct contact, form the one deck air film between the top surface of pan and panel body 1, can reduce the heat transfer of pan to panel body 1 effectively, reduce panel body 1 because overheated risk of breaking, simultaneously because the top surface direct contact of pan and wear-resisting heat conduction piece 2, the heat of pan can be passed through wear-resisting heat conduction piece 2 rapidly and is transmitted to temperature sensor 3, both can play the guard action to the panel like this, also can realize quick temperature sensing simultaneously.

Further, the side wall of the supporting portion 21 is provided with an inclined transition surface 23, and the transition surface 23 makes the part of the wear-resistant heat conducting plate 2 higher than the top surface of the panel body 1 form a structure with a small upper part and a big lower part.

When the top surface of wear-resisting heat conduction piece 2 is higher than the top surface of panel body 1, because the juncture of wear-resisting heat conduction piece 2 and panel body 1 can form the step, consequently can have the difficult problem of clearance, consequently set up transition face 23 at the upper portion lateral wall of wear-resisting heat conduction piece 2, make the lateral wall on the upper portion of wear-resisting heat conduction piece 2 form inclined straight face or arcwall face, the lateral wall that wear-resisting heat conduction piece 2 is higher than the top surface part of panel body 1 forms obtuse angle or tangent with the top surface of panel body 1 to reduce sanitary dead angle, be convenient for the user to clear up, be difficult for the dirty of containing.

Further, as shown in fig. 3, 5, 6 and 7, a thinned area is provided at the bottom of the wear-resistant heat conducting plate 2, and the temperature sensor 3 and the wear-resistant heat conducting plate 2 are propped against the thinned area.

In order to enable the temperature sensor 3 to be further close to the cooker, a thinning area is arranged at the bottom of the wear-resistant temperature guide plate 2, and when the temperature sensor 3 is installed, the temperature sensor 3 is only required to be corresponding to the thinning area; through further reducing the distance between the temperature sensor 3 and the cooker, the distance between the temperature sensor 3 and the cooker can be effectively shortened, the temperature sensor 3 can more sensitively detect the temperature of the cooker, so that the temperature of the cooker can be monitored in near real time, the cooking process can be better mastered, and when the cooker has the emergency such as dry heating, the heating can be timely stopped, and dangerous conditions are avoided. It should be noted that, for the structure with the boss at the top of the wear-resistant heat-conducting plate 2, the thinned area is located in the area of the top projection of the boss, so that the distance between the temperature sensor 3 and the pot can be ensured not to be increased even after the pot is supported by the boss.

Further, the thinned area is a containing groove 24, the top of the containing groove 24 is an arc-shaped surface arched upwards, the containing groove 24 and the containing hole 12 are filled with temperature-resistant glue 4, and the temperature sensor 3 is relatively fixed with the wear-resistant heat-conducting plate 2 through the temperature-resistant glue 4.

As one embodiment of the thinning area, a containing groove 24 is formed on the bottom surface of the wear-resistant heat-conducting plate 2, and the containing groove 24 can be formed by stamping, machining or the like; the top of the accommodating groove 24 is arched upwards, so that the thickness of the wear-resistant heat-conducting plate 2 in the thinned area is gradually changed, namely, the structure of thickness-thickness is similar to the shape of an arch bridge, and the following advantages can be brought about by the arrangement: firstly, because the top of the accommodating groove 24 is of an upward arched structure, in the assembling process, only upward pressure is needed to be applied to the temperature sensor 3, the top of the accommodating groove 24 can play a role in guiding, so that the temperature sensor 3 slides along the top surface of the accommodating groove 24 and is propped against the thinnest position of the wear-resistant heat conducting plate 2, the temperature transmission path is always shortest, and the rapid temperature sensing performance can be better exerted; secondly, the top of the accommodating groove 24 is thinned, but the top of the accommodating groove 24 is continuously variable in thickness and is arch-shaped, so that the temperature sensor 3 can have better strength even at the thinnest position, can effectively protect the temperature sensor 3, and is not easy to damage due to the impact of a cooker.

In addition, the temperature-resistant glue 4 is filled in the accommodating groove 24 and the accommodating hole 12 to fix the temperature sensor 3, so that the temperature sensor 3 can be fixed relative to the wear-resistant temperature-conducting plate 2 after assembly, and cannot move in the using process, so that the temperature sensing effect is ensured; in addition, the temperature-resistant adhesive 4 can also exhaust air between the temperature sensor 3 and the wear-resistant heat-conducting plate 2, so that the influence on the temperature transmission efficiency caused by the existence of air between the temperature sensor 3 and the wear-resistant heat-conducting plate 2 is avoided; the temperature-resistant adhesive 4 described herein refers to an adhesive that can satisfy the use environment of the rapid temperature-sensitive panel, for example, silicone adhesive, ceramic adhesive, and the like, and the components of the temperature-resistant adhesive 4 are not particularly limited.

Further, the limiting portion 22 is in clearance fit with the groove 11, and the temperature-resistant glue 4 is filled between the limiting portion 22 and the groove 11.

Therefore, a certain margin can be left when the limiting part 22 is installed in the groove 11, the situation that the wear-resistant heat-conducting plate 2 needs to be pressurized to be installed in the groove 11 is avoided, as the panel body 1 is made of glass, the panel body is brittle, particularly the corner position is easy to collapse when being impacted, the wear-resistant heat-conducting plate 2 and the groove 11 are in clearance fit, the assembly is easier, the edge position of the groove 11 can be protected, and the collapse is effectively avoided; the wear-resistant temperature-conducting plate 2 can be prevented from falling out of the groove 11 in the using process by the bonding and fixing of the temperature-resistant adhesive 4, so that the wear-resistant temperature-conducting plate 2 can be firmly fixed in the groove 11; in addition, the temperature resistant glue 4 can also play a waterproof role, when the surface of the quick temperature sensing panel is sprayed with soup, the gap between the limiting part 22 and the groove 11 is filled with the temperature resistant glue 4, so that the soup cannot infiltrate into the cooking utensil, and the electric elements and the circuits in the cooking utensil can be protected.

Further, as an alternative embodiment, the side wall of the limiting portion 22 and/or the side wall of the groove 11 are provided with bumps or glue grooves.

The setting can increase the bonding area of wear-resisting heat conduction piece 2 and/or recess 11 to improve the bonding power that wear-resisting heat conduction piece 2 bonded in recess 11, make temperature resistant glue 4 can more firmly bond wear-resisting heat conduction piece 2 in recess 11, in long-term use, wear-resisting heat conduction piece 2 is difficult for deviating from in the recess 11, and life is longer.

As shown in fig. 6 and 7, the side wall of the limiting portion 22 is inclined, so that the limiting portion 22 has a structure with a large top and a small bottom.

When the wear-resistant heat-conducting plate 2 is assembled into the groove 11, the lower part of the limiting part 22 can be easily aligned with the groove 11 and inserted into the groove 11 due to the smaller size of the lower part of the limiting part 22, so that the problem that the wear-resistant heat-conducting plate 2 collides with the top corner of the groove 11 and breaks edges when the wear-resistant heat-conducting plate 2 is aligned with and assembled into the groove 11 can be effectively reduced.

As shown in fig. 4, 5 and 7, the side walls of the groove 11 are inclined so that the groove 11 has a structure with a large upper part and a small lower part.

The arrangement can enable the side wall of the groove 11 and the side wall of the limiting part 22 to be matched with each other so as to play a better limiting role on the wear-resistant heat-conducting plate 2, and the problem of cracking caused by local stress of the side wall of the groove 11 can be avoided; in addition, the arrangement can make the top corner of the groove 11 be obtuse, so that the strength of the top corner of the groove 11 can be increased, and the problem of edge breakage can be further prevented.
