[0033] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0034] The first aspect of the utility model provides Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a heating pump cover with a temperature sensing fixture is used to be installed in a heating pump to heat water. Its main structure includes: a heating pump cover body 6, an electric heating pipe 7, a temperature sensing fixture 10, a safety control device 1 and a thermostat 2. The heating pump cover body 6 includes an outer surface 61 and an inner surface 62. In some embodiments, the heating pump cover body 6 is configured as a disc structure. The inner surface 62 is arranged opposite to the outer surface 61, and the inner surface 62 is used to contact the liquid; the electric heating tube 7 includes a heating section 71 and an end 72, and the two end 72 are connected to the heating section 71. The electric heating tube 7 is arranged on the inner surface 62, and a gap is maintained between the heating section 71 and the inner surface 62. The end 72 penetrates the heating pump cover body 6, and the end 72 extends to the outer surface 61; the temperature sensing fixture 10 includes a temperature sensing part 101 and a fixing part 102, and the temperature sensing part 101 is arranged between the inner surface 62 and the heating section 71. The two sides of the temperature sensing part 101 are in contact with the inner surface 62 and the heating section 71 respectively, and the fixing part 102 is used to clamp the heating section 71; the temperature sensing fixture 10 is configured as a heat conductive material structure. The temperature sensing fixture 10 is arranged on the inner surface 62 at the position corresponding to the safety control device 1 and the thermostat 2, so that the safety control device 1 and the thermostat 2 can more directly sense the temperature of the electric heating tube 7. Improve the accuracy of water temperature control. The safety control device 1 is arranged on the outer surface 61 at a position corresponding to the temperature sensing portion 101; the thermostat 2 is arranged on the outer surface 61, and the thermostat 2 corresponds to at least a part of the structure of the temperature sensing portion 101. In some embodiments, the thermostat 2 is arranged on the outer surface 61 at a position close to the temperature sensing portion 101.

[0035] It should be noted that since the safety control device 1 and the thermostat 2 are arranged on the heating pump cover at a position corresponding to the contact of the heating section 71 of the electric heating tube 7, and the temperature of this position is relatively sensitive, when there is air, bubbles, scale, etc. inside the heating pump, it is easy to cause detection errors to the safety control device 1 and the thermostat 2, resulting in false triggering of the safety control device 1 and the thermostat 2; in addition, the heating section 71 and the inner surface 62 of the pump cover are directly welded and contacted by nickel-based brazing, which will make it difficult to fix the heating section 71, and the temperature sensing position after welding is inaccurate.

[0036] The utility model arranges the temperature-sensing fixture 10 between the inner surface 62 of the heating pump cover body 6 and the heating section 71 to form a buffer structure for heat conduction. The temperature of the temperature-sensing fixture 10 is the temperature after the cover body and the heating element are thermally balanced after heat exchange with the water flow, which reduces the temperature sensitivity of the safety control device 1 and the thermostat 2. When air, bubbles, scale, etc. appear in the inner surface 62, causing the heating tube to have an instantaneous overtemperature, its heat will be attenuated and delayed to a certain extent through the temperature-sensing fixture 10, thereby achieving heat conduction buffering and avoiding false triggering of the safety control device 1 and the thermostat 2. In addition, the engaging part of the temperature-sensing fixture 10 is convenient for fixing the heating section 71 during production and assembly, and is easy to operate; the contact surface of the temperature-sensing fixture 10 has a regular shape, and the temperature sensing range and position after welding are relatively accurate, which improves the temperature measurement accuracy of the safety control device 1 and the thermostat 2. The temperature-sensing fixture 10 is made of a material that is easy to conduct heat, such as stainless steel, copper, aluminum, etc.

[0037] In actual use, the temperature monitored by the thermostat 2 is the temperature of the heating pump cover body 6 after heat exchange with the water flow, that is, the temperature of the water flow during normal operation can be detected by the thermostat 2, so as to control the water temperature within the set temperature range. In abnormal situations such as dry boiling due to lack of water, since there is no water to take away the heat, the temperature detected is the temperature of the electric heating tube 7 through heat conduction to the thermostat 2. When the temperature is higher than the set threshold, the power supply of the electric heating tube 7 is automatically cut off to avoid continuous temperature rise and fire and other accidents. In this way, the heating pump cover body 6 is protected, and at the same time, the effect of scaling in the heating pump cover body 6 area on the water temperature detected by the thermostat 2 can be weakened, so as to avoid the safety control device 1 and the thermostat 2 being triggered by mistake.

[0038] Further, the electric heating pipe 7 is configured as a single-layer or multi-layer structure, the end 72 penetrates the inner surface 62, and the end 72 is brazed to the inner surface 62. In some embodiments, the heat pipe is configured as a spiral tubular structure, the spiral tubular structure includes at least one spiral coil, and in some embodiments, the spiral tubular structure includes three spiral coils to increase the contact area between the electric heating pipe 7 and water and improve the heating efficiency of the electric heating pipe 7. At least one grounding plate is provided on the heating pump cover body 6, and the grounding plate is used to guide the current.

[0039] Furthermore, the heating section 71 includes a bending section 711 and a non-bending section 712 . The bending section 711 is bent toward the inner surface 62 , and both the bending section 711 and the non-bending section 712 maintain a gap with the inner surface 62 .

[0040] Furthermore, the temperature sensing portion 101 and the inner surface 62 , and the temperature sensing portion 101 and the heating section 71 are fixedly connected by brazing, and the fixing portion 102 and the heating section 71 are fixedly connected by riveting or welding.

[0041] Furthermore, the temperature sensing fixing part 10 is configured as a metal material structure, the temperature sensing part 101 and the fixing part 102 are integrally formed, the temperature sensing part 101 is configured as a flat plate structure, and the fixing part 102 is configured as an arc-shaped clamping structure, which is adapted to the electric heating tube 7 so that the temperature sensing fixing part 10 can clamp and fix the electric heating tube 7.

[0042] Furthermore, the temperature controller 2 is used to detect the temperature of the heating medium and the temperature of the heating section 71, and the safety control device 1 is used to detect the temperature of the heating section 71. The bottom of the temperature controller 2 and the safety control device 1 are both provided with a temperature sensing surface 5, and the temperature sensing surface 5 is in contact with the outer surface 61.

[0043] Furthermore, the thermostat 2 and the safety control device 1 are provided with a temperature-sensing fixing plate 3. Among them, the temperature-sensing fixing plate 33 is configured as a heat-conducting member, and mounting holes 31 are respectively provided at both ends of the temperature-sensing fixing plate 3, and the thermostat 2 and the safety control device 1 are fixed to the outer surface 61 through the mounting holes 31. In some embodiments, the temperature-sensing fixing plate 3 is a long plate-like structure or a meniscus-like structure, wherein the meniscus-like structure is an arc-shaped plate that is concave in the middle. The temperature-sensing fixing plate 3 extends along a first direction. The temperature-sensing fixing plate 3 is respectively provided with mounting holes 31 at both ends in the first direction, and the safety control device 1, the thermostat 2 and the two mounting holes 31 are arranged along the circumferential direction of the heating pump cover body 6; wherein the specific direction of the first direction is as follows: Figure 3 In some embodiments, the first direction is the circumferential direction of the heating pump cover body 6.

[0044] In this embodiment, the temperature sensing fixed plate 3 extends along the first direction, and the mounting holes 31 are opened at both ends of the temperature sensing fixed plate 3 in the first direction, which can effectively reduce the horizontal space occupied by the safety control device 1 and the thermostat 2. In one embodiment, the safety control device 1 and the thermostat 2 are fixedly arranged on the temperature sensing fixed plate 3 with a flat surface. Figure 4 Among them, two electrode sheets 11 are arranged on the safety control device 1 and the end of the temperature controller 2 away from the temperature sensing fixed plate 3.

[0045] In some embodiments, at least one riveting point is provided between the safety control device 1 and the temperature sensing fixing plate 3; at least one riveting point is provided between the thermostat 2 and the temperature sensing fixing plate 3. The through mounting hole 31 allows the lower ends of the thermostat 2 and the safety control device 1 to be directly attached to the heating pump cover body 6, so that the lower ends of the thermostat 2 and the safety control device 1 can better sense the temperature change of the heating pump cover body 6, and at the same time, the longitudinal height of the safety control device 1 and the thermostat 2 can be reduced, which is conducive to the compact design of the safety control device 1 and the thermostat 2.

[0046] In another embodiment, the mounting hole 31 does not penetrate the temperature sensing fixing plate 3. The mounting hole 31 matches the lower ends of the safety control device 1 and the thermostat 2, and the safety control device 1 and the thermostat 2 are fixed to the temperature sensing fixing plate 3 by riveting or welding. In addition, configuring the temperature sensing fixing plate 3 as a heat conductor can further help the heat of the heating pump cover body 6 to be transferred to the safety control device 1 and the thermostat 2, so that the thermostat 2 and the lower ends of the safety control device 1 can better sense the temperature change of the heating pump cover body 6.

[0047] Further, the temperature controller 2 and the safety control device 1 are respectively provided with an electrode sheet 11, and at least one electrode sheet 11 is electrically connected to the end 72. In some embodiments, the electrode sheet 11 extends in a direction away from the temperature sensing fixed plate 3, and four electrode sheets 11 are arranged along the first direction. The four electrode sheets 11 are arranged along the first direction to effectively reduce the space occupied by the electrode sheets 11 and the corresponding connecting components in the horizontal direction.

[0048] In some other embodiments, the four electrode sheets 11 are irregularly arranged to adapt to the actual installation and adaptation inside the heating pump cover body 6. Among them, the shape of the temperature sensing fixing plate 3 can be a long plate structure or a crescent-shaped flat plate structure. The mounting hole 31, the thermostat 2 and the safety control device 1 are arranged along the extension direction of the temperature sensing fixing plate 3, so as to reduce the space occupied by the safety control device 1 and the thermostat 2 in the diameter direction (radial direction) of the heating pump cover body 6 as much as possible, thereby achieving the effect of saving space.

[0049] Furthermore, the upper ends of the thermostat 2 and the safety control device 1 are provided with a connector 4, which is configured as a RAST5 structure. RAST is a connector derived from the European standard, RAST is the initials of the German word, and the Chinese meaning is standard pitch connector, while RAST 5 means a 5mm pitch standard connector. This meets the requirements of product performance, manufacturability, standardization, etc.

[0050] Furthermore, the heating pump cover body 6 is configured as a disc structure, and a through water inlet 8 is opened on the heating pump cover body 6.

[0051] In some embodiments, the upper surface of the thermostat 2 and the upper surface of the safety control device 1 are arranged in the same horizontal plane; the lower surface of the thermostat 2 and the lower surface of the safety control device 1 are arranged in the same horizontal plane so that the two are level with each other, which can further reduce the volume of the safety control device 1 and the thermostat 2, save the installation space of the safety control device 1 and the thermostat 2, and is conducive to the miniaturized design of the heating pump.

[0052] In some other embodiments, the upper surface of the thermostat 2 and the upper surface of the safety control device 1 are not in the same horizontal plane; the lower surface of the thermostat 2 and the lower surface of the safety control device 1 are not in the same horizontal plane.

[0053] Further, such as Figure 1 , Figure 3 , Figure 4 As shown, a plurality of guide plates are arranged around the edge of the inner surface 62, the plurality of guide plates are spaced a predetermined distance apart, and are arranged at an inclined angle toward the outside of the heating pump cover body 6, and the range of the inclination angle is configured to be 1° to 89°.

[0054] In summary, the present application provides a heating pump cover with a temperature-sensitive fixing part 10. The present utility model arranges the temperature-sensitive fixing part 10 between the inner surface 62 of the heating pump cover body 6 and the heating section 71 to form a heat conduction buffer structure. The temperature of the temperature-sensitive fixing part 10 is the temperature after the cover body and the heating element are thermally balanced after heat exchange with the water flow, which reduces the temperature sensitivity of the safety control device 1 and the thermostat 2, thereby greatly weakening the influence of air, bubbles, scale, etc. in the inner surface 62 on the detection accuracy of the safety control device 1 and the thermostat 2, and avoiding false triggering of the safety control device 1 and the thermostat 2; in addition, the engaging part of the temperature-sensitive fixing part 10 facilitates the fixing of the heating section 71 and is easy to operate; the contact surface of the temperature-sensitive fixing part 10 has a regular shape, and the temperature sensing range and position after welding are relatively accurate, which improves the temperature measurement accuracy of the safety control device 1 and the thermostat 2.

[0055] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
