DETAILED DESCRIPTION

[0043] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

Therefore, they cannot be understood as limitations on the present invention.

[0045] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; and direct connections or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0046] As described in the background, existing related art suffers from the technical problem of preventing foam overflow, which makes water heater installation inconvenient. Based on this, the present invention provides a housing for a water heater, comprising a rear housing and a sealing plate. The rear housing defines a mounting hole for slidingly inserting a suspension arm of a suspension member. The sealing plate is hermetically connected to the rear housing to seal the mounting hole facing the interior of the housing. The sealing plate and the rear housing also form a securing groove for securing the suspension arm. This not only facilitates installation but also prevents foam overflow.

[0047] The following describes the preferred technical solutions of the water heater 100 and its installation structure and the casing 110 provided by the present invention in conjunction with the accompanying drawings.

[0048] Figure 1 1 is a partial structural diagram of a water heater 100 connected to a suspension member 200 according to an exemplary embodiment of the present utility model; Figure 2 1 is an exploded schematic diagram of a water heater 100 and a suspension member 200 according to an exemplary embodiment of the present invention; Figure 3 yes Figure 1 Rear view of the mid-structure; Figure 4 yes Figure 3 AA section view of the middle structure; Figure 5 yes Figure 1 Left view of the middle structure; Figure 6 yes Figure 5 BB section view of the middle structure. Figure 7 2 is a schematic structural diagram of a suspension member 200 according to an exemplary embodiment of the present invention.

[0049] like Figures 1 to 6 As shown, water heater 100 includes a housing 110 and an inner tank 120 disposed within housing 110. Inner tank 120 is connected to a cold water pipe 121 and a hot water pipe 122. Housing 110 includes a front housing 111 and a rear housing 112 that are hermetically fastened together, forming a mounting cavity 113 therebetween for mounting inner tank 120. As an example, water heater 100 is a small kitchen appliance.

[0050] like Figure 1As shown, the rear housing 112 is provided with a cold water pipe installation port 1121 and a hot water pipe installation port 1122 corresponding to the cold water pipe 121 and the hot water pipe 122, respectively. A heating device (not shown) is provided in the inner tank 120, and a power supply wire is connected to the heating device for powering the heating device. The front housing 111 is provided with a through hole through which the power supply wire passes to connect to the power supply. The front housing 111 is also provided with a control panel 1111, which includes an on / off key, a temperature adjustment key, or a timer key. It is understandable that the control panel 1111 can use mechanical buttons or touch buttons.

[0051] When the water heater 100 is working, water enters the inner tank 120 through the cold water pipe 121 , and the heated water flows out through the hot water pipe 122 for use by the user.

[0052] Typically, after the inner tank 120 is installed in the housing 110, a foaming material is injected into the gap between the inner tank 120 and the housing 110 to form a dense insulation layer. Furthermore, the foaming material, after secondary foaming, can also cushion the vibrations experienced by the inner tank 120. Furthermore, the foaming material is also effectively flame-retardant, thereby improving the safety performance of the water heater 100.

[0053] Reference Figure 1 As shown, the water heater 100 is mounted on a mounting base such as a wall or a cabinet through a hanging member 200. Figure 7 As shown, the suspension member 200 includes a fixing plate 210 and a suspension arm 220 integrally formed with the fixing plate 210, wherein the fixing plate 210 is fixed to the mounting base by means of strong glue, adhesive or bolts, and the casing 110 of the water heater 100 is suspended on the suspension arm 220 to realize the installation of the water heater 100.

[0054] Specifically, if Figure 2 and Figure 4 As shown, the rear housing 112 is provided with a mounting hole 1123 for the suspension arm 220 of the suspension member 200 to slide and embed; the sealing plate 130 is sealed with the rear housing 112 to close the side of the mounting hole 1123 facing the inside of the casing 110, so that there will be no overflow when the foam is whipped, and the sealing plate 130 and the rear housing 112 are surrounded to form a fixing groove 140 for fixing the suspension arm 220, so that the user can install the water heating device 100 without having to cut the groove by himself.

[0055] It should be noted that the number of mounting holes 1123 provided on the rear housing 112 matches the number of suspension arms 220, and this is not a limitation of the present invention. In this embodiment, two suspension arms 220 are provided on the same fixing plate 210. Accordingly, two mounting holes 1123 are provided on the rear housing 112. Each mounting hole 1123 is hermetically connected to a sealing plate 130 on one side facing the interior of the housing 110, thereby forming two fixing slots 140 for securing the suspension arms 220.

[0056] In addition, in order to enable the water heater 100 to be installed upright or inverted, when the water heater 100 is installed upright, the cold water pipe 121 and the hot water pipe 122 are located above the rear housing 112; when the water heater 100 is installed inverted, the cold water pipe 121 and the hot water pipe 122 are located below the rear housing 112, and the upper and lower parts of the rear housing 112 are provided with the above-mentioned mounting holes 1123. However, it should be noted that if Figure 3 As shown, the opening direction of the fixing groove 140 formed by the sealing plate 130 and the rear housing 112 for fixing the suspension arm 220 should match the extension direction of the suspension arm 220 .

[0057] When hanging the water heater 100 on the suspension arm 220, the suspension arm 220 is first slid and embedded into the mounting hole 1123 on the rear housing 112 of the water heater 100, and then the water heater 100 slides down a distance so that the suspension arm 220 is embedded in the fixing groove 140, thereby fixing the water heater 100 on the wall or cabinet.

[0058] It is understandable that the width of the mounting hole 1123 should be slightly wider than the width of the suspension arm 220 to improve the convenience of installing the water heater 100 and prevent jamming.

[0059] The above solution not only solves the problem of foam material overflow caused by opening the installation hole 1123 on the rear housing 112, but also solves the problem that the user may not open the hole in the correct position and cannot install the hole due to the need to open the hole by himself.

[0060] In some embodiments, as Figure 2 As shown, the portion of the rear housing 112 forming the fixing groove 140 extends obliquely in the opposite direction of the sliding insertion of the suspension arm 220 toward a side away from the interior of the housing 110. This can reduce the inclination angle between the suspension arm 220 and the vertical direction, thereby improving the load-bearing capacity and stability of the suspension arm 220, thereby improving the stability of the installation of the water heater 100.

[0061] In this embodiment, the fixing plate 210 is provided with three screw holes 211, and the interconnected lines of the three screw holes 211 are arranged in a triangle. Before hanging the water heater 100, the fixing plate 210 is fixed to the wall or cabinet by three bolts.

[0062] In order to improve the strength of the fixing plate 210 and the suspension arm 220, as shown in FIG. Figure 7 As shown, the fixing plate 210 and / or the suspension arm 220 are stamped with a profiled reinforcement rib 230. The profiled reinforcement rib 230 can significantly improve the load-bearing capacity and stability of the fixing plate 210 and the suspension arm 220 without increasing the overall width of the fixing plate 210 and the suspension arm 220.

[0063] In some embodiments, the sealing plate 130 and the rear housing 112 are integrally formed, which does not require additional materials, does not increase costs, and facilitates the production of the housing 110 .

[0064] As an example, Figure 4 and Figure 6 As shown, the sealing plate 130 is configured as a rectangular parallelepiped with an opening on one side, and the opening on one side of the sealing plate 130 corresponds to the mounting hole 1123. This facilitates demoulding when the sealing plate 130 and the rear housing 112 are integrally formed.

[0065] It should be pointed out that the size of the rectangular sealing plate 130 in the front-to-back direction should correspond to the size of the suspension arm 220 protruding from the mounting plate. This can prevent the size of the sealing plate 130 in the front-to-back direction from being too large, resulting in occupying more space in the mounting cavity 113, and can also prevent the size of the sealing plate 130 in the front-to-back direction from being too small, resulting in an unstable suspension connection relationship between the suspension arm 220 and the fixing groove 140.

[0066] In some embodiments, as Figure 6 As shown, reinforcing ribs 150 are provided between the side walls of the rectangular sealing plate 130 and the rear housing 112. Preferably, multiple reinforcing ribs 150 are provided between both side walls of the sealing plate 130 and the rear housing 112. This can improve the strength of the sealing plate 130 and the rear housing 112, prevent the foaming material from squeezing the sealing plate 130 and causing deformation during the secondary foaming process, and prevent the rear housing 112 from cracking due to the excessive weight of the water heater 100.

[0067] Further preferably, a plurality of reinforcing ribs 150 are disposed near the fixing groove 140 .

[0068] In some embodiments, the rear housing 112 is provided with an embedding groove 1124 for the fixing plate 210 of the suspension member 200 to be at least partially embedded in the thickness direction. Figure 2 wherein the mounting hole 1123 is opened at the embedding groove 1124. This allows the rear housing 112 to be as close as possible to the mounting base of the water heater 100, reducing the size of the gap between the two and preventing the water heater 100 from occupying more installation space.

[0069] Reference Figure 2 As shown, the implementation principle of the installation process of a water heater 100 in an embodiment of the present invention is as follows: before installing the water heater 100, the suspension member 200 is fixedly installed on a wall or a cabinet. During the installation of the water heater 100, the installation hole 1123 on the rear housing 112 of the water heater 100 is aligned with the suspension arm 220 of the suspension member 200, and then the water heater 100 is moved so that the suspension arm 220 slides and embeds into the installation hole 1123, and then the water heater 100 slides down a certain distance so that the suspension arm 220 embeds into the fixing groove 140, thereby fixing the water heater 100 on the wall or the cabinet.

[0070] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any technician familiar with the present invention can make slight changes or modifications to equivalent embodiments using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
