Multiple heating tubes are fixed together by the folded-back sections, the opposite fixing components, and several screws and nuts. The fixed heating tube assembly is then assembled with the housing. Due to structural limitations, the assembly of the entire heating device is troublesome, making the assembly process of the heating component complicated. Summary of the Invention

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Reference Figures 2-11 A liquid heating assembly includes a first half-shell 1, a second half-shell 2, an electric heating tube assembly 4, and an electrode component 12. The first half-shell 1 and the second half-shell 2 are fixed together. The electric heating tube assembly 4 is located between the first half-shell 1 and the second half-shell 2. The first half-shell 1 has a first recess 10 on the side facing the second half-shell 2. The first recess 10 has a first portion 102 and a second portion 103. A portion of the electrode component 12 is accommodated in the second portion 103. The electrode component 12 has a second recess 1201. A portion of the electric heating tube assembly 4 is accommodated in the first portion 102. Another portion of the electric heating tube assembly 4 is accommodated in the second recess 1201. The electric heating tube assembly is in contact with the second recess. The electrode component, the electric heating tube assembly, and the first half-shell are relatively fixed.

[0031] The assembly method of the above-mentioned liquid heating assembly includes: partially accommodating the electrode component 12 along the z-axis direction in the second part 103; partially accommodating the heating tube assembly 4 along the z-axis direction in the first part 102; partially accommodating the heating tube assembly 4 along the z-axis direction in the second recess 1201, with the heating tube assembly in contact with the second recess; and fixing the second half-shell 2 to the first half-shell 1 along the z-axis.

[0032] The first half-shell 1 of this device has a first recess 10 on the side facing the second half-shell 2, and the electrode component 12 has a second recess 1201. Part of the heating tube assembly 4 is housed in the first part 102, and another part of the heating tube assembly 4 is housed in the second recess 1201, with the heating tube assembly in contact with the second recess. The first half-shell 1, electrode component 12, heating tube assembly 4, and second half-shell 2 are uniformly stacked along the z-axis direction, which not only helps reduce the use of screws and save costs, but also facilitates automated production because the assembly directions of each component are the same. In addition, because the electrode component is limited by the first recess and the heating tube assembly is limited by the second recess, their positions remain fixed when fixing the electrode component and the heating tube assembly, reducing the risk of scratching the heating film on the heating tube assembly due to errors or slippage during assembly.

[0033] refer to Figure 8 The liquid heating assembly includes a fixing member 15, an electrode component 12, and the fixing member 15 located on both sides of the heating tube assembly. The fixing member 15 has a third recess 1501, and a portion of the heating tube assembly 4 is accommodated in the third recess. The fixing member 15, the heating tube assembly, the electrode component, and the first half-shell are fixed relative to each other. More specifically, the fixing member 15 is fixed to the side of the first half-shell 1 facing the second half-shell 2. The first recess 10 and the second recess 1201 have the same recessing direction, while the third recess 1501 and the second recess 1201 of the fixing member 15 have opposite recessing directions. Thus, the second and third recesses can be used to fix the heating tubes of the heating tube assembly.

[0034] Before assembling the second half-shell 2, the fastener 15 is fixed along the z-axis to the side of the first half-shell 1 facing the second half-shell 2. The fastener 15 has a third recess 1501, and part of the heating tube assembly 4 is accommodated in the third recess. The heating tube assembly is clamped and fixed to the first half-shell 1 by the fastener 15. The assembly direction of the fastener 15 is also along the z-axis. The assembly method of stacking the first half-shell 1, electrode component 12, heating tube assembly 4, fastener 15, and second half-shell 2 in sequence can be adopted, which improves the assembly firmness of the heating tube assembly 4 and the first half-shell 1 and is conducive to realizing automated production.

[0035] refer to Figure 5 , Figure 8 , Figure 11The first half-shell has a limiting protrusion 104. The first part 102 is closer to the end of the heating tube assembly than the second part 103. The limiting protrusion is located between adjacent second parts. The electrode component 12 has a flat part 1202. The flat part has a first limiting hole 1203 and a first fixing hole 1204. The fixing member 15 has a second limiting hole and a second fixing hole. The limiting protrusion 104 is partially located in the second limiting hole. The first half-shell 1 has a third fixing hole 105. The first fixing hole, the second fixing hole, and the third fixing hole are arranged opposite to each other. The first half-shell, the electrode component, and the fixing member are fixed by screws inserted into the first fixing hole, the second fixing hole, and the third fixing hole.

[0036] During assembly, the first limiting hole 1203 of the electrode component 12 is inserted into the limiting protrusion 104 along the z-axis, the second limiting hole of the fixing component 15 is inserted into the limiting protrusion 104 along the z-axis, and the screws are sequentially inserted through the second fixing hole and the first fixing hole 1204 along the z-axis and fixedly set with the third fixing hole of the first half shell.

[0037] The electrode component 12 and the fixing member 15 are assembled along the z-axis in the first half-shell. The limiting protrusion 104 provided along the z-axis guides and limits the assembly of the electrode component 12 and the fixing member 15, reducing the assembly difficulty of the electrode component 12 and the fixing member 15. Then, screws are used to pass through the second fixing hole and the first fixing hole 1204 in sequence along the z-axis and are fixedly set with the third fixing hole of the first half-shell. The electrode component 12 and the fixing member 15 are also assembled along the z-axis, which not only makes the structural assembly more stable, but also facilitates the realization of mechanical automation assembly.

[0038] As another implementation method, specifically, refer to Figure 5 and Figure 6 The first half-shell has a main body 101 and two supports 11. The supports are located at both ends of the main body and are made of non-conductive material, such as plastic. A first recess is provided on the supports. The electrode components, heating element assembly, and supports are fixedly installed. The main body 101 is assembled on the side of the supports 11 away from the first recess along the z-axis. The supports 11 have a stepped hole 100. The larger end of the stepped hole 100 is located on the side away from the heating element assembly 4. A nut 9 is accommodated in the larger end of the stepped hole 100. A screw is threaded through the fixing member 15 and the electrode component 12 along the z-axis and threadedly connected to the nut 9 in the stepped hole 100.

[0039] The nut is inserted into the stepped hole 100 to facilitate the tightening of the screw. During assembly, the nut is first inserted into the stepped hole 100, then the electrode component 12 is installed in the first recess, then the heating tube assembly is installed on the electrode component, then the fixing piece is pressed on the electrode component, and finally the heating tube assembly is clamped and fixed on the two brackets by the cooperation of the screw and the nut. This structure enables the stacking of liquid heating components, which facilitates automated assembly.

[0040] Along the x-axis, the bracket 11 has integrally formed tapping posts 14 on both sides of the second half-shell 2. The axis of the tapping posts 14 is set along the z-axis. The first half-shell 1 and the second half-shell 2 are fixed to the tapping posts along the z-axis by screws. The first half-shell 1 and the second half-shell 2 are fixed together with the bracket 11 by screws in the z-axis direction, which is conducive to realizing the automated assembly between the bracket and the two half-shells.

[0041] As one assembly method for electric heating tube assembly 4, refer to Figure 3 The electric heating tube assembly 4 includes at least two electric heating tubes 5 arranged in the same plane. Multiple electric heating tubes 5 are connected in series along the y-axis through a U-shaped tube 8. A baffle 6 is assembled in at least one electric heating tube 5 along the y-axis. A tee pipe 7 is installed at the water inlet and / or water outlet of the electric heating tube assembly 4 along the y-axis. The electric heating tubes 5, U-shaped tube 8, baffle 6, and tee pipe 7 are assembled together along the y-axis, which reduces the assembly difficulty of the electric heating tube assembly 4 and facilitates the automated assembly of the electric heating tube assembly.

[0042] A thermostat 3 is riveted along the z-axis on the side of the first half-shell 1 away from the heating element assembly 4; and / or a thermostat 3 is riveted along the z-axis on the side of the second half-shell 2 away from the heating element assembly 4.

[0043] The bracket 11 along the z-axis has a protruding first limiting post 17 on the side opposite to the second half shell 2, and the main body has a limiting hole or limiting groove that cooperates with the first limiting post 17. The bracket 11 and the main body are assembled along the z-axis, and the first limiting post 17 is limited and cooperated with the limiting hole or limiting groove of the main body.

[0044] The bracket 11 along the z-axis has a protruding second limiting post 18 on the side away from the main body. The second half shell 2 has a limiting hole or limiting groove that mates with the second limiting post 18. The bracket 11 and the second half shell 2 are assembled along the z-axis, and the second limiting post 18 is limited and engaged with the limiting hole or limiting groove of the second half shell 2.

[0045] Both brackets 11 have buckles 16 on the side near the end of the second half shell 2, which lock and limit the two ends of the second half shell 2 along the z-axis between the buckles 16 of the two brackets 11.

[0046] Based on the above structure, when assembling this device, firstly, the second half-shell 2 is assembled with the temperature controller 3, the electric heating tube assembly 4 is assembled, and the nut 9 is pressed into the stepped hole 100 of the bracket 11. Then, the first half-shell 1, the two brackets 11, the electrode component 12, the electric heating tube assembly 4, and the fixing component 15 are stacked and assembled together from bottom to top. Then, the brackets 11, the electrode component 12, the electric heating tube assembly 4, and the fixing component 15 are locked together with screws. After that, the assembled second half-shell 2 is snapped into the bracket 11 and installed. Finally, the first half-shell 1 and the second half-shell 2 are fixed to the tapping posts 14 of the two brackets with screws, completing the assembly process of this component. Through the above structure, the assembly difficulty of the liquid heating component can be effectively reduced, which is conducive to realizing automated assembly.
