Description

Technical Field

[0001] The utility model relates to the field of heating plates, in particular to a heating plate with improved processing technology. Background Art

[0002] The heating plate is a stainless steel plate 1, an aluminum plate 2, and a heating tube 3. The high-frequency brazing machine is used to heat the weld to the melting temperature of the alloy brazing material through induction heating technology to bond the metal parts together. During welding, the high-frequency brazing machine needs to be heated at a high temperature to melt the alloy brazing material. The current heating plate structure is as follows Figure 1 As shown, a notch 4 is provided on the aluminum plate. When the thermostat is assembled and connected to the bottom surface of the aluminum plate, the temperature sensor on the thermostat will be supported on the stainless steel plate 1 through the notch. Because of the notch, in the traditional manufacturing process, the high temperature will cause the surface of the stainless steel plate corresponding to the notch to deform, resulting in a high deformation ratio of the stainless steel plate, making it difficult to control the technical points of the processing process, increasing costs and affecting the appearance. At the same time, the deformation of the stainless steel plate will also cause the temperature conduction of the temperature sensor. The temperature sensor is often affected by the heat conduction of the heating tube, resulting in misjudgment or abnormal signal problems, which will affect the consumer experience. Therefore, the applicant has provided a new technical solution to solve the above-mentioned defects by improving and perfecting the heating plate and combining the above-mentioned prior art for consumers to choose and use.

[0025] The utility model is further described below in conjunction with the accompanying drawings and embodiments. Embodiment 1:

[0026] like Figures 2 to 5 As shown, a heating plate with improved processing technology includes a stainless steel plate 1, an aluminum plate 2 welded to the bottom surface of the stainless steel plate 1, and a heating tube 3 welded to the bottom surface of the aluminum plate 2. The aluminum plate 2 is provided with a plurality of heat-resistant grooves 201, and a temperature-sensitive contact area 4 for resisting against a temperature sensor is circled on the aluminum plate 2 between the plurality of heat-resistant grooves 201.

[0027] This heating plate structure can reduce the proportion of defective products, simplify processing difficulties, improve production efficiency, and reduce processing costs. The heat signal sensed by the temperature sensor is transmitted from the stainless steel plate 1 to the aluminum plate 2, and then to the temperature sensor, solving the deformation problem of the stainless steel plate 1. In addition, a heat-resistant groove 201 is added to the aluminum plate 2 of the heating plate to isolate the heat conduction of the heating tube 3 and reduce the influence of external factors on the sensor.

[0028] Specifically, there are two heat-resistant grooves 201, both of which are semicircular structures. The two semicircular heat-resistant grooves 201 are symmetrically arranged to circle a circular temperature-sensitive contact area 4, and connecting ribs 202 connecting the aluminum plate 2 and the temperature-sensitive contact area 4 are formed between the two heat-resistant grooves 201; the number of connecting ribs 202 between the temperature-sensitive contact area 4 and the aluminum plate 2 is reduced to improve the heat-resistant effect.

[0029] The width of the heat-resistance groove 201 is preferably between 1 mm and 5 mm, and in the present embodiment, the width of the heat-resistance groove 201 is between 2 mm and 3 mm; a width of 2 mm to 3 mm provides sufficient spacing for heat resistance, thereby improving the temperature sensing accuracy of the temperature sensor.

[0030] The outer edge contour of the aluminum plate 2 is a complete circle. The aluminum plate 2 is integral, and the stainless steel plate 1 is not affected by the heating tube 3, thereby solving the deformation phenomenon. The outer edge contour of the aluminum plate 2 includes but is not limited to a complete circle. In more embodiments, the outer edge contour of the aluminum plate 2 can be a complete regular pattern.

[0031] The extension direction X1 of the connecting rib 202 is arranged perpendicular to a radial line Y1 direction of the aluminum plate 2; since the temperature-sensing contact area 4 is arranged close to the edge of the aluminum plate 2, the connecting rib 202 arranged in this way can be as far away from the weak position of the aluminum plate 2 as possible, thereby improving the connection strength between the aluminum plate 2 and the temperature-sensing contact area 4.

[0032] The heating tube 3 is in a "C"-shaped structure, the outer diameter of the heating tube 3 is the same as the diameter of the aluminum plate 2, and the temperature-sensing contact area 4 is arranged between the two ends of the heating tube 3, so that the temperature sensor can be kept away from the main heating position of the heating tube 3.

[0033] The stainless steel plate 1 and / or the aluminum plate 2 is provided with a connection structure for assembling and connecting a thermostat; the temperature sensor is assembled and connected to the thermostat, and the thermostat is connected to the bottom surface of the aluminum plate 2 through the connection structure.

[0034] The connection structure includes an internal threaded boss 5 and two buckled arch bridges 21;

[0035] The internal thread boss 5 is welded to the bottom surface of the stainless steel plate 1, and the aluminum plate 2 is provided with an avoidance hole 203 corresponding to the internal thread boss 5, and the internal thread boss 5 is arranged on the side of the aluminum plate 2 close to the temperature-sensitive contact area 4;

[0036] The two buckled arch bridges 21 are integrally formed by stamping on the other side of the aluminum plate 2 , and the two buckled arch bridges 21 are symmetrically arranged on a straight line X2 , and the internal threaded protrusions 5 are arranged on the symmetry line Y2 of the two buckled arch bridges 21 .

[0037] The thermostat has plug-in pins extending from the two buckled arch bridges 21, and connecting holes are provided corresponding to the internally threaded boss 5. During assembly and connection, a pair of plug-in pins at one end of the thermostat are inserted into the two buckled arch bridges 21, and then the connecting holes are arranged opposite to the internally threaded boss 5. Finally, after screwing in fastening units such as screws and rivets, the thermostat is fixed to the bottom surface of the aluminum plate 2. This installation method makes the heating plate suitable for automatic production lines, thereby improving the assembly efficiency of the heating plate. Embodiment 2:

[0038] The principle of the second embodiment is the same as that of the first embodiment, except that Figure 6 As shown: the heat-resistant groove 201 is an arc-shaped structure, and a plurality of arc-shaped heat-resistant grooves 201 are arranged at equal intervals along the circumferential direction to encircle a circular temperature-sensitive contact area 4, and a connecting rib 202 connecting the aluminum plate 2 and the temperature-sensitive contact area 4 is formed between two adjacent heat-resistant grooves 201.

[0039] The above is a preferred embodiment of the utility model, which shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
