[0039] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0044] The cable exit structure of water tank components typically requires pre-drilled holes in the cover. During assembly, the cable must first be passed through the exit hole in the cover, and then a sealing ring is used to seal the cover and the tank. This cable exit operation must be performed with the cover and tank not closed, increasing the complexity and time cost of assembly.

[0045] To address the aforementioned issues, this application provides a water heater, including a water tank assembly for storing and insulating water, and for transmitting water to any point of use via pipes.

[0046] The water heater also includes necessary or non-essential structures such as heat exchange components and compressors, which will not be described in detail in this application.

[0047] This application also provides a water tank assembly, such as Figures 1 to 4 As shown, in some embodiments, the water tank assembly 100 includes a tank body 110, a cover 120, and an electrical control structure 130.

[0048] The housing 110 contains a water tank, inlet pipe, and outlet pipe. The cover 120 connects to the housing 110 to form an installation space 161. The portion containing the cover 120 is typically referred to as the unit head. An electrical control box 140 is housed within the installation space 161. The electrical control box 140 contains various electrical components used to receive signals from the user or sensors and control the operation of the water heater according to a preset program. This application improves the connection structure between the housing 110, cover 120, and electrical control box 140 to simplify assembly steps and reduce time costs.

[0049] In some embodiments, the cover 120 covers one side of the housing 110, forming an installation space 161 between the cover 120 and the housing 110; the cover 120 has a clearance opening 121 communicating with the installation space 161, the clearance opening 121 providing a passage for the lead wires of the electrical control box 140 to pass through. The electrical control structure 130 includes an electrical control box 140 and a cable outlet plate 150, both of which are connected to the housing 110; electrical components are integrated within the electrical control box 140, which is located within the installation space 161; the cable outlet plate 150 is located within the clearance opening 121 and is sealed to the edge of the clearance opening 121, the cable outlet plate 150 being used for the lead wires of the electrical control box 140 to pass through. Before installing the cover 120, the electrical control box 140 and the outlet plate 150 are pre-assembled together and installed in the designated position of the housing 110. In this state, the positional relationship between the outlet plate 150 and the electrical control box 140 is fixed, which facilitates the outlet operation. Then, the cover 120 is connected to the housing 110. By adjusting the position of the cover 120 or installing it in place with the housing 110, a sealed contact is formed between the cover 120 and the outlet plate 150, which meets the waterproof or dustproof requirements when the water heater is used.

[0050] In this embodiment, during the outgoing line operation, the positional relationship between the outgoing line plate 150 and the electrical control box 140 is fixed, which avoids the outgoing line from coming off due to the relative movement of the outgoing line plate 150 and the electrical control box 140, simplifies the assembly steps, and reduces time costs.

[0051] The portion that seals the cover 120 with the outlet plate 150 is defined as the first sealing portion 122, and the first sealing portion 122 forms an avoidance opening 121 structure; the portion of the outlet plate 150 that cooperates with the first sealing portion 122 is called the second sealing portion 151.

[0052] In some embodiments, such as Figures 1 to 4As shown, the cover 120 has a closed state, which means that the cover 120 is closed on the housing 110, and the first sealing part 122 and the second sealing part 151 are in contact. During installation, the cover 120 can move in a first direction to reach the closed state. That is, the cover 120 moves in the first direction to seal the first sealing part 122 against the second sealing part 151. The movement in the first direction creates a pressure between the first sealing part 122 and the second sealing part 151, improving the reliability and stability of the seal. Furthermore, the seal can be released by moving the cover 120 in the opposite direction. When disassembling the cover 120, the lead wires are not constrained, and after disassembly, the wiring board of the electrical control box 140 is fully exposed, facilitating inspection and maintenance of the internal electrical control structure 130 and other components.

[0053] The movement of the cover 120 along the first direction can also be part of the installation process between the cover 120 and the housing 110. The cover 120's movement along the first direction has a starting position and an ending position. As the cover 120 moves from the starting position and gradually approaches the ending position, the installation and sealing process with the housing 110 is completed simultaneously. When the cover 120 reaches the ending position, it is in a closed state, and the first sealing part 122 and the second sealing part 151 abut and seal. In this embodiment, the sealing step is combined with the installation step of the cover 120, eliminating the need for a separate sealing operation after the cover 120 is installed, thereby simplifying the installation process and improving installation efficiency.

[0054] like Figures 1 to 4 As shown, to ensure that the cover 120 accurately reaches its endpoint, the housing 110 is provided with a first limiting part 111, and the cover 120 is provided with a second limiting part 123. The first limiting part 111 and the second limiting part 123 engage in a limiting cooperation. The first limiting part 111 and the second limiting part 123 can be in the form of protrusions, grooves, snaps, etc. The first limiting part 111 and the second limiting part 123 can interlock with each other when the cover 120 moves to its endpoint, thus giving the cover 120 a clear and unique endpoint position. This avoids positional deviation or instability of the cover 120 during installation, thereby ensuring the reliability and stability of the seal.

[0055] Understandably, when the cover 120 reaches the end position, fasteners can be used to lock the box 110 and the cover 120, thereby improving the stability of the connection between the cover 120 and the box 110, and keeping the first sealing part 122 and the second sealing part 151 in a resistive state, which helps to form a tight sealing interface between the first sealing part 122 and the second sealing part 151 and improves the sealing reliability.

[0056] Since the first limiting part 111 and the second limiting part 123 cooperate to limit movement along the first direction and the up and down direction, only one or two screws are needed to lock the housing 110 and the cover 120. The screws can be locked from the front of the water heater, thereby avoiding the need to reserve operating space in all directions of the water heater, improving space utilization, and adapting to the installation needs of small spaces such as cabinets.

[0057] The starting position of the cover 120 refers to the position where the cover 120 is first placed on the housing 110 during the actual assembly process. This position does not need to be unique, as long as it ensures that the cover 120 can move unimpeded to the ending position along the preset first direction from this position. Normally, when the cover 120 is at the starting position, the first limiting part 111 and the second limiting part 123 are offset along the axial direction of the water tank assembly 100 and aligned along the first direction; thus, when the cover 120 moves to the ending position along the first direction, the first limiting part 111 and the second limiting part 123 can achieve limiting cooperation in the first direction and the vertical direction.

[0058] Of course, in other embodiments, a mutually cooperating limiting structure can also be provided between the housing 110 and the cover 120 to determine a unique starting position, and this application does not limit this.

[0059] The first direction can be a circumferential direction with the central axis of the water tank assembly 100 as the center. In this case, the cover 120 rotates to reach the closed state. The first direction can also be along the front-back direction. In this case, the cover 120 moves linearly along the first direction to reach the closed state. This embodiment does not limit this.

[0060] When the cover 120 is installed by moving in the front-back direction, the front-back direction is the direction towards or away from the operating opening. For example, the water heater can be installed inside a cabinet, and the cabinet door opens to form an operating opening, from which the cover 120 can be operated.

[0061] In some embodiments, such as Figures 1 to 3 As shown, a boss 112 is formed on the top of the housing 110, and the boss 112 can be cylindrical. The top surface of the boss 112 serves as a mounting surface, providing a stable foundation for the installation of the electrical control structure 130. A stepped surface 113 is formed on the outer side of the boss 112. When the cover 120 moves downward and fits onto the outer side of the boss 112, the lower edge of the cover 120 will contact the stepped surface 113, thereby restricting further movement of the cover 120 in the vertical direction.

[0062] Before the cover 120 is installed, the first limiting part 111 and the second limiting part 123 are misaligned to avoid interference when the cover 120 begins to move. The cover 120 is moved downwards until it fits over the outside of the boss 112, and the lower edge of the cover 120 is in close contact with the stepped surface 113. Then, the cover 120 is rotated clockwise until it reaches its final position. At this point, the cover 120 is in a closed state, the second limiting part 123 engages with the first limiting part 111, and the first sealing part 122 abuts against the second sealing part 151 for a seal.

[0063] like Figures 3 to 5 As shown, the first limiting part 111 can be provided on the mounting surface. The first limiting part 111 includes a mounting section 1111, a support section 1112, a first limiting section 1113, and a second limiting section 1114. The mounting section 1111 is connected to the housing 110. The support section 1112 is connected to the mounting section 1111 and extends upward. The first limiting section 1113 is provided on the side of the support section 1112 away from the central axis. There is a gap between the first limiting section 1113 and the housing 110 for the second limiting part 123 to pass through. The second limiting section 1114 is connected to one end of the limiting section along the first direction and bends away from the housing 110. The second limiting section 1114 is used to stop the second limiting part 123 along the first direction and determine the end position of the cover 120.

[0064] In other embodiments, the first limiting part may also be a limiting groove provided on the side wall of the boss 112, and the boss 112 is also provided with a guide groove extending downward from the top of the boss 112 to communicate with the limiting groove. The second limiting part 123 moves along the guide groove to be at the same horizontal plane as the limiting groove, and the cover plate reaches the starting position; then the cover plate is rotated or moved in the first direction so that the second limiting part 123 is inserted into the limiting groove. The second limiting part 123 can cooperate with the groove wall of the limiting groove to achieve limiting in the first direction and the up and down direction, and determine the ending position of the cover 120.

[0065] A guide portion can also be provided on the top of the housing 110. When the cover 120 is installed by rotation, the guide portion can be an arc-shaped guide groove centered on the central axis of the water tank assembly 100, or it can be multiple guide protrusions spaced apart circumferentially, with the outer walls of the multiple guide protrusions being arc-shaped surfaces centered on the central axis of the water tank assembly 100. When the cover 120 is installed by moving back and forth, the guide portion can be combined with the first limiting portion 111 into the same structure, specifically, it can be a sliding groove or guide rib extending back and forth.

[0066] In some embodiments, such as Figure 2As shown, the electrical control structure 130 includes an electrical control box 140 and a cable outlet plate 150. Both the electrical control box 140 and the cable outlet plate 150 can be directly connected to the enclosure 110. Their relative positions are determined, which facilitates cable outlet operations. The electrical control box 140 can also be connected to the enclosure 110 via a mounting base plate. The cable outlet plate 150 is part of the mounting base plate. When the electrical control box 140 is connected to the mounting base plate, the electrical control box 140 and the cable outlet plate 150 are pre-assembled as an integrated structure.

[0067] When a boss 112 is formed on the top of the housing 110, the top surface of the boss 112 can serve as the mounting surface for the electrical control box 140 and the outgoing cable plate 150.

[0068] The electrical control box 140 can be installed upside down. That is, the electrical control box 140 includes a box body and electrical components. The box body has an inner cavity with an opening facing the housing 110, and the electrical components are located within the inner cavity of the electrical control box 140. Furthermore, the electrical components can be installed on the inner wall of the electrical control box 140 opposite the opening, with a certain gap between the bottom end of the electrical components and the opening. This allows condensate to drain under gravity, preventing the electrical components from being immersed in accumulated condensate.

[0069] The cable outlet plate 150 is provided with a cable outlet for the lead wires of the power control box 140 to pass through. A cable sealing connector 152 may be provided at the cable outlet. The cable sealing connector 152 is a standard part in this field. The specific structure of the cable sealing connector 152 is not described in detail in this embodiment. The cable sealing connector 152 can adjust the size of the cable outlet channel to seal and contact cables of different diameters.

[0070] like Figure 2 and Figure 6 As shown, the outlet plate 150 has a second sealing portion 151, which abuts against and seals with the first sealing portion 122 of the cover 120. Understandably, the bottom edge of the outlet plate 150 contacts the housing 110, and the second sealing portion 151 can be provided along the remaining edges of the outlet plate 150 except for the bottom edge, thereby forming a continuous sealing interface with the first sealing portion 122.

[0071] Specifically, the second sealing structure includes a first folding plate 1511, a second folding plate 1512, and a third folding plate 1513. The first folding plate 1511 and the second folding plate 1512 are spaced apart along a first direction, and the third folding plate 1513 is located on the side of the first folding plate 1511 and the second folding plate 1512 away from the housing 110. The first folding plate 1511 and the second folding plate 1512 form a sealing surface on the same side along the first direction, and the second folding plate 1512 forms a sealing surface on the side away from the housing 110.

[0072] Taking the cover 120 rotating to the closed state as an example, a sealing surface is formed on the right side of the first folding plate 1511 and the second folding plate 1512. The sealing surfaces of the first folding plate 1511 and the second folding plate 1512 are arranged opposite to the first sealing part 122 in the first direction. Thus, the cover 120 rotates clockwise to the closed state. The first sealing part 122 can press against the sealing surfaces of the first folding plate 1511 and the second folding plate 1512, and the force driving the cover 120 to rotate is converted into the pressure of the first sealing part 122 against the sealing surfaces of the first folding plate 1511 and the second folding plate 1512.

[0073] The sealing surface of the third fold plate 1513 is formed on the top of the third fold plate 1513. When the cover 120 is in the starting position, the first sealing part 122 can partially contact the sealing surface of the third fold plate 1513. When rotating, it slides along the sealing surface of the third fold plate 1513 until the cover 120 reaches the closed state. The first sealing part 122 and the sealing surface of the third fold plate 1513 form a continuous sealing interface along the first direction. The right end of the third fold plate 1513 forms a continuous sealing interface extending to the box 110 through the sealing surface of the first fold edge 1221 and the first sealing part 122. The left end forms a continuous sealing interface extending to the box 110 through the sealing surface of the third fold plate 1513 and the first sealing part 122.

[0074] In other embodiments, when the cover 120 is in the starting position, the sealing surfaces of the first sealing part 122 and the third folding plate 1513 may not be in contact at all. During the rotation of the cover 120, the contact area between the sealing surfaces of the first sealing part 122 and the second folding plate 1512 is continuously increased until a closed state is reached; when the cover moves to the ending position, it reaches a closed state, and the positional relationship between the first sealing part 122 and the second sealing part 151 is the same as before, which will not be described in detail in this embodiment.

[0075] The first folding plate 1511 and the second folding plate 1512 bend in different directions. The direction towards the central axis of the water tank assembly 100 is defined as inside, and the direction away from the central axis of the water tank assembly 100 is defined as outside. Then, the first folding plate 1511 bends towards the inside of the outlet plate 150, and the second folding plate 1512 bends towards the outside of the outlet plate 150, thereby avoiding interference between the first sealing part 122 and the first folding plate 1511 or the second folding plate 1512 during the rotation of the cover 120.

[0076] Specifically, the third folding plate 1513 is located inside the outlet plate 150, and the right end of the third folding plate 1513 is connected to the upper end of the first folding plate 1511. The sealing surface of the third folding plate 1513 is continuous with the sealing surface of the first folding plate 1511. The left end of the third folding plate 1513 extends to be flush with the second folding plate 1512, and the upper end of the second folding plate 1512 protrudes from the third folding plate 1513. The protruding part of the second folding plate 1512 presses against the first sealing part 122 to form a continuous sealing interface in the front-back direction. This sealing interface connects the sealing interface formed at the second folding plate 1512 and the sealing interface formed at the third folding plate 1513.

[0077] It should be noted that the sealing surfaces on the first folding plate 1511, the second folding plate 1512, and the third folding plate 1513 all have a width that extends in the front-back direction. As a result, the first sealing part 122 can overlap with the sealing surfaces on the first folding plate 1511, the second folding plate 1512, and the third folding plate 1513 in the front-back direction, thereby improving the waterproof effect.

[0078] To optimize the sealing effect, such as Figure 2 , Figure 6 and Figure 7 As shown, the second sealing part 151 may include a plate 1514 and an elastic sealing gasket 1515. The first folding plate 1511, the second folding plate 1512 and the third folding plate 1513 each have a corresponding plate 1514 and an elastic sealing gasket 1515. The side of the elastic sealing gasket 1515 away from the corresponding plate 1514 forms a sealing surface. The first sealing part 122 presses against the sealing surface, that is, the first sealing part 122 compresses the elastic sealing gasket 1515, thereby improving the waterproof effect and meeting the dustproof requirements.

[0079] For example, when the cover 120 rotates clockwise, the first sealing part 122 contacts the sealing surface, and the cover 120 continues to rotate clockwise a certain distance, so that the first limiting part 111 and the second limiting part 123 are in a limiting engagement, reaching the end position. In this case, the first sealing part 122 can cause the elastic sealing gasket 1515 to form a certain compression distance.

[0080] The second sealing part 151 may also include a plate 1514 and multiple waterproof ribs, with a groove formed between two adjacent waterproof ribs. A portion of the structure of the first sealing part 122 extends into any groove and abuts against the plate 1514. The folded edge can cover the point where the first sealing part 122 presses against the sealing surface, reducing the risk of water entering through the gap between the first sealing part 122 and the sealing surface, thereby improving the waterproof effect. Alternatively, an elastic sealing gasket 1515 may be provided on the plate 1514 at the position corresponding to the groove, with the first sealing part 122 extending into the groove and pressing against the elastic gasket.

[0081] In some embodiments, such as Figures 2 to 4 As shown, the cover 120 has an inner cavity with a bottom opening, the cover 120 has a relief opening 121, and the edge of the relief opening 121 has a first sealing part 122. The inner wall of the cover 120 is provided with a second limiting part 123. When the cover 120 moves to the closed state along the first direction, the second limiting part 123 and the first limiting part 111 limit and cooperate in the first direction and the up and down direction, and the first sealing part 122 and the second sealing part 151 abut and seal.

[0082] With a boss 112 on the top of the housing 110, when installing the cover 120, the cover 120 is moved downwards so that it can fit over the outside of the boss 112, thereby closing the opening at the bottom of the cover 120 to form an installation space 161, allowing the electrical control box 140 to be housed within the installation space 161. The cover 120 and the boss 112 cooperate to achieve radial limiting and guide the rotation of the cover 120.

[0083] Specifically, the cover 120 includes a base plate 124 and a side panel 125. The side panel 125 is connected to the edge of the base plate 124, and the side panel 125 of the base plate 124 forms an inner cavity with a bottom opening. In the first example of the above embodiment, the clearance opening 121 can be directly formed on the side panel 125, and the first limiting part 111 is connected to the side panel 125 and is provided along the edge of the clearance opening 121, simplifying the overall structure of the cover 120.

[0084] In the second example of the above embodiments, such as Figure 7 As shown, the clearance opening 121 can also be located inside the side panel 125 and surrounded by the first limiting part 111. In this case, the side panel 125 should have a notch 126, and the first sealing part 122 is connected to the side panel 125 to form a wire passage connecting the notch 126 and the clearance opening 121. Thus, the side panel 125 can play a certain shielding role, preventing the contact sealing of the first sealing part 122 and the second sealing part 151 from being exposed, improving the overall aesthetics and protection.

[0085] like Figure 6 As shown, the second sealing part 151 includes a first folding plate 1511, a second folding plate 1512, and a third folding plate 1513, corresponding to which, as Figure 2 , Figure 7 and Figure 8As shown, the first sealing part 122 includes a first folded edge 1221, a second folded edge 1222, and a third folded edge 1223. The first folded edge 1221 and the second folded edge 1222 are spaced apart along a first direction, and the third folded edge 1223 connects the first folded edge 1221 and the second folded edge 1222. The first folded edge 1221, the second folded edge 1222, and the third folded edge 1223 abut against the second sealing part 151 to form a continuous sealing interface. Specifically, when the cover 120 is in the closed state, the first folded edge 1221 abuts against the sealing surface of the first folded plate 1511, the second folded edge 1222 abuts against the sealing surface of the second folded plate 1512, and the third folded edge 1223 abuts against the sealing surface of the third folded plate 1513, together forming a continuous sealing interface, effectively preventing the intrusion of external substances such as moisture and dust.

[0086] This applies to the case where the first folding plate 1511 is located on the inner side of the outlet plate 150, and the second folding plate 1512 is located on the outer side of the outlet plate 150. For example... Figure 2 , Figure 4 and Figure 9 As shown, the second fold 1222 can be a first sub-fold 1221a and a second sub-fold 1221b. The upper end of the first sub-fold 1221a is connected to the second sub-fold 1221b. One inward end of the second sub-fold 1221b protrudes from the first sub-fold 1221a. The second sub-fold 1221b abuts and seals with the protruding part of the second fold plate 1512. The lower end of the part of the second sub-fold 1221b that protrudes from the first sub-fold 1221a is connected to the third fold 1223. A continuous sealing interface is formed by the abutting of the second sub-fold 1221b with the protruding part of the second plate 1514.

[0087] Based on the second example above, such as Figure 3 and Figure 7 As shown, the cover 120 may have a water-blocking fold 127. The vertical projection area of ​​the water-blocking fold 127 on the surface where the cable outlet plate 150 is located can cover the abutment of the third fold 1223 and the third fold plate 1513, thereby playing a shielding role and preventing water droplets from directly acting on the abutment seal of the third fold 1223 and the third fold 1223.

[0088] The water-blocking fold 127 can be disposed on the inner side of the side panel 125. The left and right sides of the water-blocking fold 127 are respectively connected to the first fold 1221 and the second fold 1222. The top of the water-blocking fold 127 is directly connected to the base plate 124. The third fold plate 1513 can be connected to the inner side of the water-blocking fold 127.

[0089] The first folded edge 1221 is connected to the side panel 125, specifically to the edge of the notch 126. The first folded edge 1221 can be bent to the right to form a water-blocking structure. The second folded plate 1512 is connected to the side panel 125, specifically to the edge of the notch 126. The second folded edge 1222 can be bent to the left to form a water-blocking structure. Thus, the size of the notch 126 is smaller than the size of the outlet plate 150. The first folded edge 1221 bends to form a water-blocking structure to cover the pressure sealing area between the first folded edge 1221 and the first folded plate 1511. The second folded edge 1222 bends to form a water-blocking structure to cover the pressure sealing area between the second folded edge 1222 and the second folded plate 1512.

[0090] Furthermore, such as Figure 3 , Figure 7 and Figure 10 As shown, the outer side of the side panel 125 is also provided with a protruding water-blocking rib 128. The water-blocking rib 128 is located outside the notch 126, guiding the water droplets on the outer side of the side panel 125 to flow along the water-blocking rib 128, reducing the probability of the water droplets flowing to the through-line channel.

[0091] like Figure 2 and Figure 4 As shown, the second limiting part 123 can be a limiting protrusion formed on the inner wall of the cover 120. The limiting protrusion can be limited and engaged with the first limiting segment 1113 of the first limiting part 111 in the vertical direction, and can also be limited and engaged with the second limiting segment 1114 of the first limiting part 111 in the first direction to determine the end position of the cover 120. Alternatively, the limiting protrusion can move along the guide groove and move into the limiting groove. The limiting protrusion can be limited and engaged with the inner wall of the limiting groove in the first direction and the vertical direction to determine the end position of the cover 120.

[0092] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
