[0042] A heating assembly such as a dry heater generally has a heating tube and a sleeve, wherein the sleeve is arranged inside the inner tank, and the heating tube is placed in the sleeve. When the heating tube is working, the heating tube is energized to convert electrical energy into heat energy, and the heat is exchanged with the water in the inner tank through the sleeve, thereby heating the water in the inner tank.

[0043] However, the heating tube in the related art is fixed in the sleeve with a nut structure. When installing the heating tube, it is necessary to first install the heating tube into the sleeve, adjust the angle of the heating tube, install the support sheet on the stud, and then fix the nut on the stud; when the heating tube needs to be disassembled, the nut needs to be loosened and removed, the support sheet needs to be removed, and then the heating tube needs to be taken out. During this disassembly process, the space available for tightening and removing the nut is small, which is inconvenient to operate and inefficient.

[0044] Based on this, the utility model proposes a heating assembly 100, which is intended to disassemble and assemble the heating tube 2 without tightening the nut, thereby simplifying the operation difficulty and improving the disassembly and assembly efficiency of the heating tube. The structure of the heating assembly 100 is described below in the form of an embodiment.

[0045] See also Figures 1 to 6 In the embodiment of the utility model, the heating assembly 100 includes a sleeve assembly 1, a heating tube 2, a fixing column 13 and a support member 3.

[0046] One end of the sleeve assembly 1 is closed and the other end is open; the heating tube 2 is arranged in the sleeve assembly 1 and partially extends out of the open end of the sleeve assembly 1; the fixing column 13 is arranged at the open end of the sleeve assembly 1, and the fixing column 13 is provided with a clamping groove 131; the support member 3 is installed on the fixing column 13, and the support member 3 includes a clamping portion 31 that can clamp or disengage from the clamping groove 131 and a support portion 32 connected to the clamping portion 31;

[0047] When the clamping portion 31 is clamped in the clamping slot 131 , the supporting portion 32 supports the portion of the limiting heating tube 2 extending out of the sleeve assembly 1 ; when the clamping portion 31 is disengaged from the clamping slot 131 , the supporting portion 32 can move relative to the fixing portion 13 to release the heating tube 2 .

[0048] In this embodiment, one end of the sleeve assembly 1 is closed and the other end is open. The closed end is used to extend into the inner tank of the water heater, and the open end is used for the heating tube 2 to be inserted into the sleeve assembly 1. The sleeve assembly 1 can protect the heating tube 2 and prevent the heating tube 2 from directly contacting the water in the inner tank of the water heater. The heating tube 2 partially extends out of the open end of the sleeve assembly 1 to be electrically connected to the power supply outside the sleeve assembly 1 to ensure the normal operation of the heating tube 2.

[0049] The open end of the sleeve assembly 1 is provided with a fixing column 13, and a support member 3 is arranged on the fixing column 13. The support member 3 cooperates with the fixing column 13 to achieve the function of supporting and limiting the heating tube 2. Specifically, the fixing column 13 is provided with a slot 131, and the support member 3 includes a clamping portion 31 and a supporting portion 32. The clamping portion 31 is used to clamp and cooperate with the slot 131 of the fixing column 13, and the supporting portion 32 is used to support and limit the heating tube 2. The supporting portion 32 can achieve the function of supporting and limiting or releasing the heating tube 2 through the cooperation state of the clamping portion 31 and the slot 131:

[0050] When installing the heating tube 2, first insert the heating tube 2 into the sleeve assembly 1, then move the support portion 32 to a position that matches the heating tube 2, and then clamp the clamping portion 31 in the clamping groove 131 to limit and fix the support portion 32, so that the support portion 32 can support and limit the portion of the heating tube 2 that extends out of the sleeve assembly 1, thereby achieving the installation of the heating tube 2;

[0051] When disassembling the heating tube 2, first disengage the clamping portion 31 from the clamping groove 131 so that the supporting portion 32 can move relative to the fixing column 13, and then move the supporting portion 32 to a position disengaged from the heating tube 2. The staff can then disassemble the heating tube 2 from the sleeve assembly 1, thereby achieving disassembly of the heating tube 2.

[0052] It should be noted that the present embodiment adopts a snap-fitting mode between the support member 3 and the fixing column 13. Compared with the operation of tightening a nut in the related art, the installation structure of the present embodiment is simpler and faster, and the disassembly and assembly efficiency of the heating tube 2 is higher.

[0053] It is understandable that the fixing column 13 can be configured as a column structure extending from the end surface of the sleeve assembly 1 away from the sleeve assembly 1, which can provide more installation space for the support member 3. Optionally, the fixing column 13 can be welded, screwed or integrally formed with the sleeve assembly 1.

[0054] It is understandable that the support member 3 is installed on the fixed column 13, and the support member 3 can be sleeved on the fixed column 13, or can be inserted on the fixed column 13, as long as the clamping portion 31 of the support member 3 and the clamping groove 131 of the fixed column 13 can be easily clamped or disengaged. Optionally, the clamping groove 131 can be a groove structure arranged on the outer peripheral wall of the fixed column 13, or can also be a groove structure radially penetrating the fixed column 13. The clamping portion 31 can be an elastic clamping structure, a hook structure or other special-shaped structures. The support portion 32 is fixed by clamping the clamping portion 31 with the fixed column 13. It is understandable that the support portion 32 can be a support structure that pushes the heating tube 2 toward the inside of the sleeve assembly 1; or the support portion 32 can also be a clamping structure that clamps and fixes the part of the heating tube 2 that extends out of the sleeve assembly 1.

[0055] Optionally, the clamping portion 31 and the supporting portion 32 may be an integral structure or a separate structure.

[0056] In summary, in the heating assembly 1 of the technical solution of the utility model, the heating tube 2 is arranged in the sleeve assembly 1 and partially extends out of the open end of the sleeve assembly 1. By arranging a fixing column 13 and a support member 3 at the open end of the sleeve assembly 1, the fixing column 13 is provided with a slot 131, and the support member 3 includes a clamping portion 31 and a supporting portion 32. The supporting portion 32 can be fixed by the clamping and matching of the clamping portion 31 and the slot 131, so that the supporting portion 32 can support and limit the portion of the heating tube 2 extending out of the sleeve assembly 1, thereby realizing the fixed installation function of the heating tube 2; at the same time, the supporting portion 32 can also be disengaged from the slot 131 by the clamping portion 31 and can be moved to release the heating tube 2, thereby realizing the disassembly function of the heating tube 2. In this embodiment, the support member 3 is clamped and matched with the fixing column 13, so that the disassembly and assembly operation of the heating tube 2 can be realized only by plugging and unplugging, clamping, etc., which simplifies the operation difficulty and improves the disassembly and assembly efficiency of the heating tube 2 compared to the method of screwing the nut.

[0057] In one embodiment of the present application, Figures 2 to 4 The clamping groove 131 is an annular groove provided on the outer peripheral wall of the fixing column 13 ; the clamping portion 31 is an elastic clamp used to be clamped in the annular groove so that the supporting portion 32 presses against the heating tube 2 in the direction of the sleeve assembly 1 .

[0058] In this embodiment, when the clamping portion 31 is clamped in the clamping groove 131, the groove wall of the clamping groove 131 will abut against the end of the clamping portion 31 away from the heating tube 2. At this time, the groove wall of the clamping groove 131 can limit the clamping portion 31 in the up and down directions, thereby realizing the limiting support function of the support portion 32, thereby ensuring the reliability of the limiting support of the heating tube 2 by the support portion 32.

[0059] By configuring the slot 131 as an annular slot and the clamping portion 31 as an elastic clamp, it is easier to clamp the clamping portion 31 outside the fixing column 13 , while increasing the matching area between the slot wall of the slot 131 and the clamping portion 31 , further improving the supporting strength.

[0060] In one embodiment of the present application, Figures 3 to 6 The clamping portion 31 includes two clamping arms 311, which are clamped on both sides of the fixing column 13 and limited in the clamping groove 131; the supporting portion 32 is connected to the ends of the two clamping arms 311 and extends in a direction away from the fixing column 13 to cooperate with the heating tube 2.

[0061] In this embodiment, the two clamping arms 311 are respectively arranged on both sides of the fixing column 13 and clamped in the clamping slot 131 to achieve the limitation in the up and down direction. The support part 32 is connected to the ends of the two clamping arms 311 close to the heating tube 2, so that when the two clamping arms 311 are limited and fixed in the clamping slot 131, the support part 32 can press against the heating tube 2 in the direction of the sleeve assembly 1 to fix the heating tube 2 to the sleeve assembly 1.

[0062] In actual application, when the heating tube 2 needs to be installed, the two clamping arms 311 can be first pried apart to allow the support member 3 to be installed on the fixing column 13, and the support portion 32 can be adjusted to a position against the heating tube 2. Then, the pulling force applied to the two clamping arms 311 can be released. The two clamping arms 311 can be reset to the slot 131 under the action of their own elastic force and be fixed in a limited position, thereby limiting the support portion 32, so that the support portion 32 presses against the heating tube 2 in the direction of the sleeve assembly 1, thereby fixing the heating tube 2.

[0063] When the heating tube 2 needs to be disassembled, the two clamping arms 311 can be opened to disengage the clamping arms 311 from the slots 131 , and then the support portion 32 is moved to a position away from the heating tube 2 to eliminate the resisting force on the heating tube 2 .

[0064] Furthermore, if Figures 3 to 6 The clamping arm 311 includes a connecting section 3111, a clamping section 3112 and an opening section 3113 which are connected in sequence, the connecting section 3111 connects the clamping section 3112 and the supporting portion 32, the clamping section 3112 is clamped in the slot 131, and the opening section 3113 is arranged at the free end of the clamping section 3112; in the clamping portion 31, the distance between the two opening sections 3113 is greater than the distance between the two clamping sections 3112; and / or, the distance between the two connecting sections 3111 is greater than the distance between the two clamping sections 3112.

[0065] In this embodiment, the clamping section 3112 is a structure that matches the slot 131. The two clamping sections 3112 are clamped on both sides of the fixing column 13 and abut against the slot wall of the slot 131. The connecting section 3111 is used to connect the clamping section 3112 and the support portion 32, and separate the support portion 32 from the clamping section 3112, so that the strength of the support portion 32 will not be affected by the opening or clamping action of the clamping section 3112, and the supporting strength of the support portion 32 for the heating tube 2 can be ensured. The opening section 3113 is provided at the free end of the clamping section 3112, and is used for the staff to pry it open.

[0066] By making the distance between the two opening sections 3113 larger than the distance between the two clamping sections 3112, it is convenient for workers to open the heating tube 2, thereby further improving the efficiency of disassembly and assembly of the heating tube 2.

[0067] By making the distance between the two connecting sections 3111 larger than the distance between the two clamping sections 3112, the connecting section 3111 can also become a portion for the staff to pry it apart for operation, which further improves the staff's operational convenience and makes the disassembly and assembly efficiency of the heating tube 1 higher.

[0068] In practical applications, the specific structure of the clamping section 3112 can be determined according to actual conditions, for example, it can be a straight arm structure, an arc-shaped arm structure or other types of structures, as long as it can ensure that the clamping section 3112 and the fixing column 13 can be clamped and matched.

[0069] Alternatively, if Figure 5 The clamping section 3112 is a straight arm structure, and the two clamping sections 3112 in the clamping portion 31 are arranged in parallel. Such an arrangement can simplify the molding process of the clamping portion 31 and improve production efficiency.

[0070] Alternatively, if Figure 6 The clamping section 3112 is provided with a groove 311a on one side facing the fixing column 13, and the groove wall shape of the groove 311a is adapted to the groove bottom wall shape of the slot 131. Such a configuration can increase the matching degree of the clamping section 3112 and the fixing column 13, increase the matching area of ​​the two, and further improve the matching strength of the two.

[0071] In order to further improve production efficiency, in one embodiment, the clamping arm 311 can be an integral structure, and the connecting section 3111, the clamping section 3112 and the opening section 3113 are formed by a bending process. In practical applications, the clamping portion 31 and the supporting portion 32 can also be integrally formed to improve production efficiency.

[0072] In one embodiment of the present application, Figure 4 The portion of the heating tube 2 extending out of the sleeve assembly 1 includes two terminal blocks 21 arranged at an angle, and the support portion 32 is located between the two terminal blocks 21 and presses the two terminal blocks 21 toward the sleeve assembly 1 .

[0073] It can be understood that the two terminals 21 of the heating tube 2 extending out of the sleeve assembly 1 are respectively the positive terminal and the negative terminal of the heating tube 2. The two terminals 21 are arranged at an angle to form a "V"-shaped structure, so that the two terminals 21 have sufficient creepage distance to prevent short circuit between the two. By locating the support part 32 between the two terminals 21 and pressing the two terminals 21 toward the sleeve assembly 1, the support force of the support part 32 on the heating tube 2 is more balanced, which can prevent the heating tube 2 from tilting and improve the installation reliability of the heating tube 2.

[0074] Furthermore, the width of the support portion 32 is gradually reduced from the clamping portion 31 toward the direction away from the fixing column 13. Such a configuration makes it easier to install the support portion 32 between the two wiring terminals 21, further improving the assembly efficiency.

[0075] In one embodiment of the present application, Figures 1 to 4The sleeve assembly 1 includes a sleeve 11 and a flange mounting seat 12, one end of the sleeve 11 is closed and the other end is open; the flange mounting seat 12 is connected to the open end of the sleeve 11 and is open at a position corresponding to the sleeve 11; the heating tube 2 is arranged in the sleeve 11 and extends out of the flange mounting seat 12; the fixing column 13 is arranged at the end of the flange mounting seat 12 away from the sleeve 11; the support member 3 is installed on the fixing column 13, and the support part 32 presses against the heating tube 2 in the direction of the sleeve 11.

[0076] This embodiment illustrates the structure of the sleeve assembly 1, where the sleeve 11 is mounted on one end of the flange mounting seat 12. Optionally, the sleeve 11 and the flange mounting seat 12 may be integrally formed or welded as separate structures. When applied to a water heater, the flange mounting seat 12 is fixed on the inner tank, and the sleeve 11 is located inside the inner tank. The position of the flange mounting seat 12 corresponding to the sleeve 11 is open, so that the heating tube 2 can extend from the outside of the flange mounting seat 12 into the inside of the sleeve 11, and in order to facilitate electrical conduction with the outside, the heating tube 2 partially extends out of the flange mounting seat 12.

[0077] In order to facilitate the installation of the support member 3, the fixing column 13 can be set as a column structure extending from the end surface of the flange mounting seat 12 away from the sleeve 11, so as to provide more installation space for the support member 3. Optionally, the fixing column 13 can be welded, screwed or integrally formed with the flange mounting seat 12.

[0078] In this embodiment, a fixing column 13 is provided at the end of the flange mounting seat 12 away from the sleeve 11, and the support member 32 is installed on the fixing column 13 through the clamping portion 31, so that the support portion 32 can push and fix the heating tube 2 toward the sleeve 11. Such a configuration further simplifies the installation structure and improves the efficiency of assembly and disassembly.

[0079] The utility model also provides an electric water heater, such as Figure 7 The electric water heater comprises an inner tank 200 and a heating assembly 100. The specific structure of the heating assembly 100 is referred to the above embodiment. Since the electric water heater adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here. Among them, the sleeve 11 of the heating assembly 100 extends into the inner tank 200, and the flange mounting seat 12 of the heating assembly 100 is fixed to the tank opening 201 of the inner tank 200.

[0080] In this embodiment, the inner tank 200 has a water inlet pipe 310 and a water outlet pipe 320. The water inlet pipe 310 is used to bring cold water into the inner tank 200, and the water outlet pipe 320 is used to discharge hot water from the inner tank 200. The inner tank 200 is provided with a tank opening 201. By fixing the flange mounting seat 12 to the tank opening 201, the function of fixing the sleeve 11 inside the inner tank 200 is realized. The heating tube 2 is installed in the sleeve 11, and the water in the inner tank 200 is heated by the sleeve 11. When the heating tube 2 fails, there is no need to remove the flange mounting seat 12 or drain the water in the inner tank 200. The heating tube 2 can be directly removed, and the disassembly and installation are very simple.

[0081] In practical application, the inner tank 200 of the electric water heater can be a horizontal inner tank or a vertical inner tank. The tank opening 201 can be arranged at the bottom, side or top of the inner tank 200.

[0082] In one embodiment of the present application, the opening 201 is provided at the bottom of the inner tank 200. With such a configuration, the heating assembly 100 is inserted into the inner tank 200 from bottom to top through the opening 201. At this time, the heating assembly 100 is located in the lower area of ​​the inner cavity of the inner tank 200, which can more conveniently heat the cold water located at a lower position and improve the heating efficiency. In this embodiment, the heating tube 2 is inserted into the sleeve 11 from bottom to top, and the heating tube 2 is supported and fixed by the cooperation of the support member 3 and the fixing column 13 at the bottom.

[0083] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
