Description

Technical Field

[0001] This utility model relates to the field of water heater technology, and in particular to thermostat installation structure, thermostat components and gas water heater. Background Technology

[0002] A gas water heater is a heating device that uses gas as fuel to quickly produce hot water through combustion. The thermostat in a gas water heater plays a crucial role in accurately controlling the outlet water temperature; therefore, the thermostat's detection sensitivity and accuracy are important. Existing thermostats generally have a mounting base. Current technology typically involves clamping the thermostat to the water pipe with a mounting clip, then using bolts to secure the base to the mounting clip's connecting lugs. However, current technology usually requires two bolts to fix the thermostat, resulting in low installation efficiency. Utility Model Content

[0003] The first technical problem solved by this utility model is to provide a thermostat installation structure that can solve the problem of low installation efficiency of existing thermostat components.

[0004] The second technical problem solved by this utility model is to provide a thermostat assembly with a thermostat mounting structure that can solve the problem of low installation efficiency of existing thermostat assemblies.

[0005] The third technical problem solved by this utility model is to provide a gas water heater with a thermostat assembly that can improve the installation efficiency of the thermostat.

[0006] The first technical problem mentioned above is solved by the following technical solution:

[0007] A thermostat mounting structure is provided, including a mounting clip and a base connected to the thermostat, wherein the mounting clip includes:

[0008] A clamp body having an opening;

[0009] A first connecting ear and a second connecting ear, wherein the first connecting ear is connected to one side of the opening of the clamp body and has a plug-in groove, and the second connecting ear is connected to the other side of the opening of the clamp body;

[0010] One end of the base is inserted into the insertion slot; the other end of the base is locked to the second connecting ear by a fastener; a clamping space is formed between the base and the clamp.

[0011] Compared with the prior art, the thermostat installation structure of this utility model has the following advantages: Since the first connecting ear of the clamp is provided with a plug-in groove, and the base of the thermostat is inserted into the plug-in groove, the first connecting ear can replace part of the function of the fastener. Then, the base of the thermostat and the second connecting ear are locked together by the fastener, so that the base of the thermostat is connected to the two points of connection. The base and the clamp together hold the support, such as the object of action of the thermostat. The support is located in the clamping space, so that the thermostat can be installed with only one fastener, thereby improving the installation efficiency of the thermostat.

[0012] In one embodiment, the top of the clamp is narrowed inward to form the opening.

[0013] In one embodiment, the end of the first connecting ear away from the clamp is folded upward to form a bent flange, and the insertion groove is formed in the bent flange, the insertion groove extending through the bent flange along the thickness direction of the bent flange.

[0014] In one embodiment, the bending flange includes a first flange and a second flange connected to each other. The first connecting ear has a first mounting plane that abuts against the base. The first flange connects the first mounting plane and the second flange. The insertion slot is formed in the first flange. The second flange is pressed against the upper surface of the base.

[0015] In one embodiment, the thermostat mounting structure further includes a limiting member, which includes two oppositely arranged spring pieces connected to the clamp, and the two spring pieces are respectively located on opposite sides of the opening, with the minimum distance between the two spring pieces being less than the width of the opening.

[0016] In one embodiment, the thermostat mounting structure includes two sets of limiting members, which are respectively disposed at both ends of the clamp along the length direction of the clamp.

[0017] The second technical problem mentioned above is solved by the following technical solution:

[0018] A thermostat assembly is provided, including a thermostat and a thermostat mounting structure according to any of the above embodiments, wherein the thermostat is fixed on the base and the temperature sensing part of the thermostat is exposed on the base.

[0019] Compared with the prior art, the thermostat assembly of this utility model has the following advantages: The thermostat assembly has the thermostat mounting structure of any of the above embodiments. Because the first connecting ear has a insertion slot, one end of the thermostat base is inserted into the insertion slot. Thus, the first connecting ear can replace part of the function of the fastener. The base and the second connecting ear are then locked together using fasteners, forming two connections on the base. This provides constraint in both the horizontal and vertical directions, allowing the thermostat to be installed using only one fastener, thereby improving installation efficiency. The clamp is clamped to a support object, such as the object to which the thermostat operates, through an opening, eliminating the need for complex processing such as welding, thus reducing processing costs. Furthermore, the temperature-sensing part of the thermostat is exposed on the base, enabling direct contact between the thermostat and the object, which helps improve detection accuracy and precision sensitivity.

[0020] The third technical problem mentioned above is solved by the following technical solution:

[0021] A gas water heater is provided, including an installation pipe and the aforementioned thermostat assembly;

[0022] The clamp is held in place by the mounting tube through an opening; the temperature sensing part abuts against the outer wall of the mounting tube.

[0023] Compared with the prior art, the gas water heater of this utility model has the following advantages: the thermostat assembly of the gas water heater uses an open mounting clip to position the thermostat on the mounting pipe, and the temperature sensing part of the thermostat is in direct contact with the outer wall of the mounting pipe, which helps to improve detection accuracy and precision sensitivity. The installation of the thermostat base on the mounting clip requires only one fastener, simplifying the installation process and improving the production efficiency of gas water heaters.

[0024] In one embodiment, along the axial direction of the mounting tube, the outer wall of the mounting tube has two recessed second positioning planes on both sides, and the inner side of the clamp has two oppositely arranged third positioning planes, with the two second positioning planes abutting against the two third positioning planes respectively.

[0025] In one embodiment, the outer wall of the mounting tube has a first positioning plane, and the temperature sensing part is attached to the first positioning plane. Attached Figure Description

[0044] Example 1

[0045] like Figures 1-5 As shown, this utility model embodiment first provides a thermostat mounting structure, which includes a mounting clip and a base 201 connected to the thermostat 200. The mounting clip includes a clip body 1, a first connecting ear 2, and a second connecting ear 3. The clip body 1 has an opening 11, through which the clip body 1 is clamped to the mounting tube 100, making installation relatively convenient. The first connecting ear 2 is connected to one side of the opening 11 of the clip body 1, and a plug-in groove 21 is provided on the first connecting ear 2; the second connecting ear 3 is connected to the other side of the opening 11 of the clip body 1. One end of the base 201 is plugged into the plug-in groove 21, and the other end of the base 201 is locked to the second connecting ear 3 by a fastener, forming a clamping space between the base 201 and the clip body 1. Since one end of the base 201 connected to the thermostat 200 is inserted into the insertion slot 21, the first connecting ear 2 can replace part of the function of the fastener. Then, the fastener is used to lock the base 201 and the second connecting ear 3 together, so that the base 201 can be constrained in both the horizontal and vertical directions. Thus, only one fastener is needed to make the thermostat 200 installed securely, thereby improving the installation efficiency of the thermostat 200.

[0046] The shape of the insertion slot 21 matches the shape of the insertion part of the base 201 of the thermostat 200, so that the thermostat 200 can be subjected to strong constraint in both the horizontal and vertical directions, resulting in better installation stability. The second connecting ear 3 has a mounting hole 31, and the base 201 of the thermostat 200 has a through hole corresponding to the mounting hole 31. The fastener can be a screw, which passes through the through hole and the mounting hole 31. One of the through hole and the mounting hole 31 is a smooth hole, and the other is a threaded hole.

[0047] Along a cross-section perpendicular to the length of clamp 1, the top of clamp 1 is narrowed inward to form an opening 11. The width of the opening 11 is less than or equal to the maximum width of clamp 1, such as... Figure 2 As described in the figure, L1 is the width of the opening 11. L1 is smaller than the maximum width L2 of the clamp 1, which makes the clamping more reliable and reduces the risk of the clamp 1 falling off the mounting tube 100.

[0048] The end of the first connecting ear 2 furthest from the clamp 1 is folded upward to form a bent flange 23. A insertion groove 21 is formed in the bent flange 23 and extends through the bent flange 23 along its thickness direction. The base 201 is inserted horizontally into the insertion groove 21 on the first connecting ear 2 for easy installation.

[0049] The bent flange 23 includes a first flange 231 and a second flange 232 connected to each other. The first connecting ear 2 has a first mounting surface 22 that abuts against the base 201. The first flange 231 connects the first mounting surface 22 and the second flange 232. A insertion slot 21 is formed in the first flange 231. The second connecting ear 3 has a second mounting surface 32. The first mounting surface 22 and the second mounting surface 32 are coplanar, providing a stable mounting surface for the base 201 of the thermostat 200. The insertion slot 21 is inclined relative to the first mounting surface 22. When one end of the base 201 is inserted into the insertion slot 21, the base 201 can always abut against the first mounting surface 22 and the second mounting surface 32, maintaining installation stability.

[0050] The second flange 232 is pressed against the upper surface of the base 201. The first connecting ear 2 has a first mounting plane 22, which reduces the upward extension height of the bent flange 23 relative to the first mounting plane 22, reducing the risk of interference with other components. Moreover, it increases the contact friction between the second flange 232 and the base 201, reducing the risk of the base 201 disengaging from the insertion slot 21.

[0051] Example 2

[0052] This embodiment two provides a thermostat mounting structure, which has some of the same structure as in embodiment one. This embodiment will not elaborate on the same structure.

[0053] The difference in this embodiment is that, Figure 6 and Figure 7 As shown, the thermostat mounting structure also includes a limiting member 4, which includes two oppositely arranged spring pieces 41. The spring pieces 41 are connected to the clamp body 1, and the two spring pieces 41 are located on opposite sides of the opening 11. The minimum distance between the two spring pieces 41 is less than the width of the opening 11. The limiting member 4 further increases the reliability of the mounting clip holding the mounting tube 100 and reduces the risk of the mounting clip falling off the mounting tube 100 during the assembly process.

[0054] Figure 7 As shown, L1 is the width of the opening 11, L3 is the minimum distance between the two spring pieces 41, and L3 < L1.

[0055] Example 3

[0056] This third embodiment provides a thermostat mounting structure, which has some of the same structural features as that in embodiment one. Therefore, this embodiment will not elaborate on the identical structures. The difference in this third embodiment is that, as... Figure 8 As shown, the thermostat mounting structure includes two sets of limiting members 4. Each set of limiting members 4 includes two oppositely arranged spring pieces 41. The spring pieces 41 are connected to the clamp body 1, and the two spring pieces 41 are located on opposite sides of the opening 11. The minimum distance between the two spring pieces 41 is less than the width of the opening 11. Along the length direction of the clamp body 1, the two sets of limiting members 4 are respectively arranged at both ends of the clamp body 1. In this way, one spring piece 41 is arranged on each side of the first connecting ear 2, and one spring piece 41 is arranged on each side of the second connecting ear 3. The two sets of limiting members 4 clamp the mounting tube 100 at two points along the axial direction. Compared with the single-sided limiting member 4 structure in Embodiment 2, the double-sided limiting members 4 clamp the mounting tube 100 more reliably, improving the axial position accuracy of the thermostat mounting structure on the mounting tube 100.

[0057] Example 4

[0058] Embodiment 4 of this utility model provides a temperature controller assembly, such as... Figures 9 to 11 As shown, the thermostat assembly includes the thermostat mounting structure as described in any of the above embodiments. The thermostat assembly also includes a thermostat 200, which is fixed to the base 201. The temperature sensing part of the thermostat 200 is exposed outside the base 201. The thermostat assembly is mounted on the mounting tube 100. The clamp 1 of the thermostat mounting structure is clamped to the mounting tube 100 through the opening 11. The exposed temperature sensing part is used to measure the temperature of the outer wall of the mounting tube 100.

[0059] The thermostat mounting structure features a insertion slot 21 on the first connecting ear 2, allowing the base 201 of the thermostat 200 to engage with it. This allows the first connecting ear 2 to perform some of the functions of a fastener. Fasteners are then used to securely connect the base 201 of the thermostat 200 to the second connecting ear 3, ensuring the thermostat 200 is constrained both horizontally and vertically. This allows for stable installation of the thermostat 200 using only one fastener, thus improving installation efficiency. The clamp 1 is mounted on the mounting tube 100 through the opening 11, eliminating the need for complex processes such as welding and reducing manufacturing costs. The opening 11 has a dual effect: on the one hand, it improves the convenience of clamping the clamp 1 onto the mounting tube 100 and makes it easier to assemble and disassemble the clamp 1; on the other hand, the temperature sensing part exposed on the base 201 can directly contact the outer wall of the mounting tube 100 through the opening 11, and the temperature controller 200 can directly monitor the temperature of the mounting tube 100, which helps to improve the detection accuracy and precision sensitivity.

[0060] This fourth embodiment also provides a gas water heater, which includes a thermostat assembly as described above and an installation pipe 100. The clamping space formed between the base 201 and the clamp 1 is used to accommodate the installation pipe 100. The thermostat assembly uses an installation clamp with an opening 11 to position the thermostat 200 on the installation pipe 100. The temperature sensing part of the thermostat 200 is in direct contact with the outer wall of the installation pipe 100, which helps to improve detection accuracy and precision sensitivity. Moreover, the installation of the base 201 of the thermostat 200 only requires one fastener, simplifying the installation steps and improving the production efficiency of the gas water heater.

[0061] Optionally, the outer wall of the mounting tube 100 is recessed to form a second positioning plane 102, and the inner side of the clamp 1 has a third positioning plane 12 and an arc-shaped positioning surface 13 (see reference). Figure 1 The second positioning plane 102 abuts against the third positioning plane 12, and the arc-shaped positioning surface 13 fits against the arc-shaped peripheral surface of the mounting tube 100. The combination of the third positioning plane 12 and the arc-shaped positioning surface 13 reduces the probability of the clamp 1 rotating on the mounting tube 100, thus maintaining the positional stability of the temperature controller 200.

[0062] In another embodiment, along the axial direction of the mounting tube 100, the outer wall surface of the mounting tube 100 has two opposingly arranged second positioning planes 102, and the inner side of the clamp 1 has two third positioning planes 12 and an arcuate positioning surface 13 located between the two third positioning planes 12 (see reference). Figure 1 The two second positioning planes 102 respectively abut against the two third positioning planes 12, and the arc-shaped positioning surface 13 fits against the circumferential side of the mounting tube 100. The two third positioning planes 12 of the mounting tube 100 and the mounting clip form two surface contacts, reducing the probability of rotation of the mounting clip and improving the circumferential position accuracy of the mounting clip on the mounting tube 100.

[0063] To increase the contact area with the base 201 of the thermostat 200, the outer wall of the mounting tube 100 has a first positioning plane 101, and the temperature sensing part of the thermostat 200 is in contact with the first positioning plane 101 (reference). Figure 5 The surface contact between the base 201 and the first positioning plane 101 can increase the heat transfer area and improve the detection accuracy of the temperature controller 200.

[0064] In another embodiment, the outer wall of the mounting tube 100 has an arc-shaped surface, a portion of which abuts against the temperature-sensing part of the thermostat 200, i.e., a line contact is formed between the base 201 and the mounting tube 100. This line contact also allows the thermostat 200 to directly monitor the temperature of the mounting tube 100.

[0065] When the wall thickness of the mounting tube 100 is small, the first positioning plane 101 and the second positioning plane 102 can be formed by the tube wall being recessed inward along the thickness direction toward the axial direction.

[0066] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0067] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
