Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a housing assembly for a water heater and a water heater. Background Technology

[0002] A kitchen water heater is a small electric water heater specifically designed for kitchens. It's primarily used to quickly provide hot water for daily kitchen needs, such as washing dishes, vegetables, and hands. Kitchen water heaters are compact, provide hot water instantly, are energy-efficient, and have adjustable temperatures. They can be categorized into storage-type and instantaneous-type kitchen water heaters, depending on whether they have a storage tank. Storage-type kitchen water heaters have a built-in tank that preheats and stores a certain amount of hot water, making them suitable for households with high water usage. Instantaneous-type kitchen water heaters do not have a storage tank; they use a high-power heating element to instantly heat the water, resulting in a smaller size but higher power consumption.

[0003] The housing assembly of an instant water heater typically includes an interlocking front and rear shell, which together form a cavity for housing the inner liner. The front of the front shell has mounting positions for components such as the power board and thermostat. The housing assembly also includes a maintenance cover that conceals the components on the front shell. To facilitate removal of the maintenance cover from the front shell for inspection, the maintenance cover is usually detachably attached. However, instant water heaters in this technology often have the following problems: 1) The maintenance cover easily loosens after several removals. If it falls off during use, the components on the front shell will be exposed, affecting the safety of the water heater; 2) There is a gap between the center of the maintenance cover and the front shell. After long-term use, the maintenance cover easily collapses towards the side closer to the front shell, affecting the aesthetic appearance of the instant water heater.

[0004] Therefore, there is an urgent need to propose a housing assembly for a water heater and a water heater in order to solve the above problems. Utility Model Content

[0043] Before explaining any embodiment of the present invention in detail, it should be understood that the present invention is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0044] In this invention, the terms "comprising," "including," "having," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0045] In this invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following related objects have an "and / or" relationship.

[0046] In this invention, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0047] In this invention, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0048] In this invention, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can be performed by one part, one component, or a combination of multiple parts.

[0049] In this utility model, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this utility model. Furthermore, in the context, it should be understood that when one element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent the direct orientation but can also be understood as the lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0050] Figure 1 A schematic diagram of the structure of the housing assembly for a water heater provided in this embodiment is shown. Figure 2 An exploded view of the housing assembly for a water heater provided in this embodiment is shown. Figure 1 and Figure 2 As shown, this embodiment provides a water heater, which includes a front shell 10, a rear shell (not shown in the figure), and an inner tank (not shown in the figure). The front shell 10 has a receiving chamber 101, the inner tank is received in the receiving chamber 101, and the rear shell covers the opening of the receiving chamber 101, thereby realizing the reception and protection of the inner tank.

[0051] In this embodiment, the front shell 10 and the rear shell are fixed together by fasteners, which facilitates disassembly and assembly and ensures a stable connection. Specifically, the front shell 10 is provided with a first connecting hole 104, and the rear shell is provided with a second connecting hole corresponding to the first connecting hole 104. Fasteners are sequentially inserted through the first connecting hole 104 and the second connecting hole, thereby realizing a detachable connection between the front shell 10 and the rear shell. Optionally, there are multiple first connecting holes 104, which are spaced apart circumferentially along the front shell 10. Each first connecting hole 104 corresponds to a second connecting hole, thereby further improving the stability of the connection between the front shell 10 and the rear shell.

[0052] Of course, in other embodiments, the front shell 10 and the rear shell can also be connected by snap-fit ​​or plug-in, which is not limited here.

[0053] Figure 3 A schematic diagram of the front shell 10 provided in this embodiment is shown. Figure 3 and combined Figure 2 As shown, the front cover 10 has a first mounting groove 105 and a second mounting groove 106 on the side opposite to the receiving chamber 101. The first mounting groove 105 is used to install the power board, and the second mounting groove 106 is used to install the thermostat of the water heater. Optionally, fixing holes are also provided around the first mounting groove 105 for installing screws. The screws can limit the power board installed in the first mounting groove 105 to prevent it from shifting or falling out during use.

[0054] The water heater also includes a service cover 20, which covers the side of the front housing 10 opposite to the receiving chamber 101 to shield and protect the power board and thermostat. The front housing 10 and the service cover 20 together form the housing assembly of the water heater. Optionally, the service cover 20 is detachably installed on the front housing 10 to facilitate removal by an operator for inspection and maintenance of the components (power board and thermostat) mounted on the front housing 10.

[0055] Figure 4 A cross-sectional view of the housing assembly for a water heater provided in this embodiment is shown. Figure 5 It shows Figure 4 A magnified view of a portion at point A. Figure 6 It shows Figure 4 A magnified view of point B. (See image below.) Figures 4-6 As shown, the front cover 10 has a first snap-fit ​​hole 111 and an anti-detachment part 12; the maintenance cover 20 is provided with a first buckle 21 corresponding to the first snap-fit ​​hole 111 and an anti-detachment part 22 corresponding to the anti-detachment part 12. When the maintenance cover 20 is closed on the front cover 10, the anti-detachment part 22 abuts against the anti-detachment part 12 and the first buckle 21 is locked in the first snap-fit ​​hole 111.

[0056] The water heater housing assembly provided in this embodiment achieves a detachable connection between the front housing 10 and the maintenance cover 20 by providing a first snap-fit ​​hole 111 and a first buckle 21 on the front housing 10 and maintenance cover 20 respectively. By providing an anti-detachment part 12 on the front housing 10 and an anti-detachment part 22 on the maintenance cover 20 that can cooperate with the anti-detachment part 12, when the maintenance cover 20 is closed on the front housing 10, the anti-detachment part 22 abuts against the anti-detachment part 12, thereby causing the first buckle 21 to be locked in the first snap-fit ​​hole 111, so as to prevent the maintenance cover 20 from falling off the front housing 10 during use, which would expose the components installed on the front housing 10 and affect the overall safety of the water heater.

[0057] Figure 7 It shows Figure 3 A magnified view of a portion of the image. Figure 8 A schematic diagram of the structure of the maintenance cover 20 provided in this embodiment is shown. Figure 9 It shows Figure 8 A magnified view of point C. (See attached image.) Figures 7-9 and combined Figure 4 As shown, the first buckle 21 is inserted into the first snap-fit ​​hole 111 from the side facing the anti-detachment part 12. The anti-detachment part 12 is provided with a first abutting surface 121 facing the first snap-fit ​​hole 111, and the anti-detachment member 22 is provided with a second abutting surface 2221 that abuts against the first abutting surface 121. That is, when the maintenance cover 20 is sealed on the front shell 10, the first buckle 21 and the anti-detachment member 22 are both located between the first snap-fit ​​hole 111 and the anti-detachment part 12. The first buckle 21 is inserted into the first snap-fit ​​hole 111 from right to left, and the second abutting surface 2221 of the anti-detachment member 22 presses against the first abutting surface 121 of the anti-detachment part 12 to the right, thereby preventing the first buckle 21 from coming out of the first snap-fit ​​hole 111, and thus preventing the maintenance cover 20 from coming out of the front shell 10.

[0058] It should be noted that, for ease of description, in this embodiment, directional terms such as "up," "down," "left," and "right" are specifically used in the context of... Figure 2 The placement shown is the standard, that is, when the maintenance cover 20 is sealed on the front shell 10, the maintenance cover 20 is located above the front shell 10, and the first buckle 21 is located to the left of the anti-detachment component 22. However, it is not "up", "down", "left" or "right" in the spatial sense of the housing assembly for the water heater in actual application, but is only used to distinguish different features and cannot be used as a limitation on the technical solution of this application.

[0059] like Figure 4 , Figure 7 and Figure 9As shown, the first abutment surface 121 gradually slopes upwards in a direction away from the first snap-fit ​​hole 111, and the second abutment surface 2221 can fit against the first abutment surface 121. With this arrangement, when the operator needs to remove the maintenance cover 20 from the front shell 10, the maintenance cover 20 can be pushed to the right, so that the second abutment surface 2221 slides along the inclined first abutment surface 121, thereby causing the first snap-fit ​​21 to disengage from the first snap-fit ​​hole 111, completing the separation and disassembly of the maintenance cover 20 from the front shell 10.

[0060] Optionally, a first guide slope 122 is provided on the side of the anti-detachment part 12 opposite to the first snap-fit ​​hole 111. The first guide slope 122 gradually slopes upward in the direction close to the first snap-fit ​​hole 111. The anti-detachment part 22 is provided with a second guide slope 2222 that cooperates with the first guide slope 122. With this arrangement, when the maintenance cover 20 is installed on the front shell 10, the operator can place the second guide slope 2222 of the first buckle 21 against the first guide slope 122, and then push the maintenance cover 20 to the left so that the second guide slope 2222 slides along the first guide slope 122. During this process, the first buckle 21 can gradually extend into the first snap-fit ​​hole 111. When the anti-detachment part 22 passes the connection between the first guide slope 122 and the first abutment surface 121, the second abutment surface 2221 abuts against the first abutment surface 121, and the first buckle 21 is installed in place with the first snap-fit ​​hole 111.

[0061] Figure 10 It shows Figure 8 A magnified view of a portion of the image. For example... Figure 10 As shown, the first latch 21 includes a second connecting portion 211 and a latching portion 212 that are angled together and connected to each other. The second connecting portion 211 is connected to the maintenance cover 20, and the latching portion 212 can extend into the first latching hole 111. In other words, the first latch 21 has an approximately L-shaped structure, which allows the first latch 21 to smoothly extend into the first latching hole 111 when the operator pushes the maintenance cover 20 relative to the front cover 10.

[0062] like Figure 7 and Figure 9 As shown, the anti-detachment component 22 includes a first connecting portion 221 and a mating portion 222 that are angled together and connected to each other. The first connecting portion 221 is connected to the maintenance cover 20, and there is a gap between the mating portion 222 and the maintenance cover 20. A second abutting surface 2221 and a second guide slope 2222 are both provided on the mating portion 222. By providing a gap between the mating portion 222 and the maintenance cover 20, sufficient space can be provided for the deformation of the anti-detachment component 22 when the maintenance cover 20 is assembled with the front shell 10.

[0063] like Figure 3 and Figure 8As shown, a recessed area 102 is formed on the front shell 10, and a first annular rib 11 is provided in the recessed area 102. The first annular rib 11 and the inner wall of the recessed area 102 form a limiting groove 103. The inner side of the maintenance cover 20 extends vertically to form a second annular rib 23. When the maintenance cover 20 is closed on the front shell 10, the second annular rib 23 is inserted into the limiting groove 103. In this embodiment, the first buckle 21 and the anti-detachment component 22 are both located in the annular space surrounded by the second annular rib 23. The first snap-fit ​​hole 111 is opened on the first annular rib 11, and the first mounting groove 105 and the second mounting groove 106 are both opened in the recessed area 102. The inner side of the maintenance cover 20 refers to the side of the maintenance cover 20 facing the front shell 10. By setting the first annular rib 11 and the second annular rib 23, the stability of the connection between the front shell 10 and the maintenance cover 20 can be improved, and the sealing of the entire water heater shell assembly can be guaranteed.

[0064] like Figure 4 , Figures 6-9 As shown, the maintenance cover 20 is also provided with a second buckle 231, and the front shell 10 is provided with a second snap-fit ​​hole 112 corresponding to the second buckle 231, so that the second buckle 231 can snap into the second snap-fit ​​hole 112. In this embodiment, the second buckle 231 is provided on the second annular rib 23, and the second snap-fit ​​hole 112 is opened on the first annular rib 11 and is opposite to the first snap-fit ​​hole 111; when the second annular rib 23 is inserted into the limiting groove 103, the second buckle 231 can extend into the second snap-fit ​​hole 112 from right to left. By providing the second buckle 231, it can cooperate with the first buckle 21 to further ensure the stability of the connection between the maintenance cover 20 and the front shell 10. When the maintenance cover 20 is installed on the front housing 10, the second annular rib 23 is inserted into the limiting groove 103. During the process of the operator pushing the maintenance cover 20 from right to left relative to the front housing 10, the first latch 21 can engage with the first latching hole 111, and simultaneously the second latch 231 can engage with the second latching hole 112. Furthermore, as... Figure 4 As shown, when the maintenance cover 20 is placed on the front shell 10, the second buckle 231 is located in the limiting groove 103 and extends into the second locking hole 112 from right to left. The anti-detachment part 22 and the anti-detachment part 12 abut against each other, which can also make the second buckle 231 lock in the second locking hole 112, so as to prevent the second buckle 231 from falling out of the second locking hole 112 during use.

[0065] like Figure 7 , Figure 8 and Figure 10As shown, at least one connecting rib 14 connects the first annular rib 11 and the inner wall of the recessed area 102. The connecting rib 14 can improve the structural strength of the first annular rib 11 and prevent it from shifting relative to the front shell 10 after multiple disassemblies and reassemblies. Optionally, the second annular rib 23 is provided with a relief groove 232 to avoid the connecting rib 14, so that the connecting rib 14 can be avoided and accommodated after the maintenance cover 20 is assembled with the front shell 10. Optionally, the relief groove 232 is L-shaped. When the maintenance cover 20 is closed on the front shell 10, the L-shaped relief groove 232 can accommodate and limit the connecting rib 14 to prevent it from coming out of the relief groove 232 during use.

[0066] In this embodiment, the first annular rib 11 is a roughly square annular structure formed by four strip ribs connected end to end. The first snap-fit ​​hole 111 and the second snap-fit ​​hole 112 are respectively formed on two opposite strip ribs. When the first snap-fit ​​21 is engaged in the first snap-fit ​​hole 111 and the second snap-fit ​​231 is engaged in the second snap-fit ​​hole 112, the first snap-fit ​​21 and the second snap-fit ​​231 can support the two strip ribs. Connecting ribs 14 connect the other two opposite strip ribs to the inner wall of the recessed area 102. This arrangement simplifies the structure of the front shell 10 and the maintenance cover 20 while ensuring their structural strength.

[0067] Understandably, when the maintenance cover 20 is placed over the front shell 10, the first snap-fit ​​hole 111 and the second snap-fit ​​hole 112 on the first annular rib 11 are both blocked by the second annular rib 23. This design can prevent the foaming material from overflowing from the front shell 10 through the first snap-fit ​​hole 111 or the second snap-fit ​​hole 112 when the insulation layer is being foamed in the accommodating chamber 101, thus avoiding contamination of the exterior of the front shell 10. This ensures the aesthetics of the water heater after installation and eliminates the need for subsequent cleaning, saving installation time. In addition, this design can also eliminate the need for a sponge strip, saving material costs and improving the assembly efficiency of the water heater.

[0068] like Figure 3 and Figure 7 As shown, at least one support post 15 is provided on the front shell 10 (specifically within the recessed area 102), and the support post 15 can abut against the inner side of the maintenance cover 20. By providing the support post 15, the maintenance cover 20 can be supported to prevent the middle of the maintenance cover 20 from collapsing, thereby ensuring the aesthetic appearance of the entire water heater shell assembly. When the number of support posts 15 is greater than or equal to two, the support posts 15 are arranged around the mounting opening 107 of the front shell 10. The mounting opening 107 of the front shell 10 is used for installing the inner tank.

[0069] In some embodiments, an injection port 16 is provided on the front shell 10 (specifically within the recessed area 102). The injection port 16 is used to inject foaming material from the side of the front shell 10 near the maintenance cover 20 into the receiving chamber 101. That is, after the front shell 10 and the rear shell are assembled, the foaming material can be injected from the outside of the receiving chamber 101 through the injection port 16 into the space between the cavity wall and the inner liner of the receiving chamber 101. This allows the foaming material to be conveniently injected into the receiving chamber 101 in the optimal injection method using a spray gun or other auxiliary tools, filling the space between the cavity wall and the inner liner of the receiving chamber 101, thereby effectively preventing overflow. Optionally, the number of injection ports 16 is at least two, and at least two injection ports 16 are arranged around the mounting port 107. This embodiment does not limit the specific number of injection ports 16, and designers can adjust the number and arrangement of injection ports 16 according to actual injection requirements.
