[0044] like Figures 1 to 4As shown, this embodiment provides a water heater housing 100, including a bottom shell 1, a front shell assembly 2, and a display bracket 3. The bottom shell 1 has an inner cavity 1a with a front opening 1b, the front shell assembly 2 is covered on the front side of the bottom shell 1 and closes the front opening 1b, the front shell assembly 2 includes a panel portion 20 and a flanged frame 21 arranged around the periphery of the panel portion 20, the flanged frame 21 has a connecting flange 211 opposite to the panel portion 20 and arranged at intervals, the connecting flange 211 is detachably connected to the bottom shell 1, and the display bracket 3 includes a bracket body 30, the bracket body 30 is provided with connecting ears 31 protruding outwardly on opposite sides in the left and right directions, and an avoidance groove is provided on the connecting flange 211 21a, the avoidance groove 21a and the connecting ear 31 are arranged in a one-to-one correspondence, the connecting ear 31 can pass through the avoidance groove 21a and be inserted between the connecting flange 211 and the panel part 20, and the connecting ear 31 and the connecting flange 211 are detachably connected, wherein the up, down, left, right, front, and rear directions described in this article are when the water heater housing 100 is in use, with the direction toward the user as the front, the direction away from the user as the rear, the left direction of itself as the left, the right direction of itself as the right, and the up and down directions as the up and down directions of itself along the gravity direction, such as Figures 1 to 4 As shown, Figure 1 , Figure 2 and Figure 4 The coordinates in FIG. 1 show the up, down, left, right, front, and rear directions of the water heater housing 100 in the use state. Figure 3 The arrows in the figure show the up, down, left, right, front and rear directions of the water heater housing 100 in the use state.

[0045] By setting corresponding avoidance grooves 21a on the connecting flange 211, the connecting ears 31 on the left and right sides of the display bracket 3 can pass through the avoidance grooves 21a to be inserted between the connecting flange 211 and the panel part 20, so that the connecting ears 31 can extend to the edge close to the flange frame 21, and can avoid the situation where the edge of the connecting ear 31 extends between the connecting flange 211 and the bottom shell 1. In other words, the connection tightness between the connecting flange 211 and the bottom shell 1 will not be affected by the connecting ears 31, thereby making the connection tightness at the edge of the face shell assembly 2 and the bottom shell 1 better, and the waterproof performance of the water heater shell 100 better.

[0046] In one embodiment, the connecting flange 211 is further provided with a first connecting hole 21b, and the first connecting hole 21b corresponds to the avoidance groove 21a one by one, and all the first connecting holes 21b are located on the same side of the corresponding avoidance groove 21a in the up-down direction, and the spacing distances between all the first connecting holes 21b and the corresponding avoidance groove 21a are equal. The connecting ear 31 is connected to the connecting flange 211 by a first fastener 22 passed through the first connecting hole 21b, so that the multiple connecting ears 31 included in the display bracket 3 can simultaneously pass through the corresponding avoidance groove 21a to enter between the connecting flange 211 and the panel part 20, and then the display bracket 3 is moved as a whole in the up-down direction so that the multiple connecting ears 31 are simultaneously aligned with the corresponding first connecting holes 21b.

[0047] In one embodiment, the first fastener 22 may include but is not limited to bolts, screws, rivets, etc., and the first fastener 22 may be fixedly arranged on the connecting ear 31, or the connecting ear 31 may be provided with a through hole, and the first fastener 22 may pass through the through hole and the first connecting hole 21b in sequence to connect the connecting ear 31 with the connecting flange 211. When the first fastener 22 includes a threaded member such as a bolt or a screw, the through hole on the connecting ear 31 may be a threaded hole so that the first fastener 22 can be threadedly connected to the connecting ear 31, or the first fastener 22 may also include a nut to be threadedly connected to the threaded member through the nut, so that the head of the threaded member and the nut are clamped on two opposite sides of the connecting ear 31 and the connecting flange 211.

[0048] When the first fastener 22 partially protrudes from the side of the connecting flange 211 facing the bottom shell 1, optionally, the first fastener 22 partially passes through the front opening 1b. In other words, the first fastener 22 is staggered with the bottom shell 1 to avoid interference between the first fastener 22 and the bottom shell 1.

[0049] In one embodiment, the bracket body 30 may be provided with a plurality of connecting ears 31 along at least one side in the left-right direction, and the plurality of connecting ears 31 are spaced apart along the up-down direction. The connecting flange 211 includes two first flanges 211a spaced apart from each other along the left-right direction, and the two first flanges 211a are both provided with avoidance grooves 21a. Correspondingly, at least one first flange 211a may be provided with a plurality of avoidance grooves 21a and corresponding first connecting holes 21b. The plurality of avoidance grooves 21a are spaced apart along the up-down direction, thereby increasing the number of connection positions between the display bracket 3 and the first flange 211a on at least one side in the left-right direction, thereby improving the connection stability between the display bracket 3 and the first flange 211a on at least one side in the left-right direction.

[0050] In one embodiment, the first flange 211a is also provided with a plurality of latching protrusions 212 arranged at intervals along the up-down direction, and the bottom shell 1 is also provided with a plurality of first latching grooves 11 corresponding to the plurality of latching protrusions 212. The latching protrusions 212 can be detachably latched in the corresponding first latching grooves 11, so that the first flange 211a and the bottom shell 1 can be better connected tightly by the latching protrusions 212 and the first latching grooves 11.

[0051] Preferably, among the plurality of protrusions 212, at least some of the protrusions 212 are arranged corresponding to the avoidance groove 21a, and the protrusions 212 are connected to the groove wall of the corresponding avoidance groove 21a, so that at least some of the protrusions 212 can be made of the material of the first flange 211a that is originally located inside the avoidance groove 21a. In other words, when manufacturing the avoidance groove 21a and the corresponding protrusions 212, the material of the part of the first flange 211a located inside the avoidance groove 21a can be removed by stamping, and the remaining part of the material located inside the avoidance groove 21a is formed into the protrusions 212, thereby making it possible to more efficiently utilize the production raw materials and reduce the manufacturing cost of the flanged frame 21.

[0052] In one embodiment, the connecting flange 211 also includes a second flange 211b located at the lower side of the flange frame 21, and the lower side of the bracket body 30 is also provided with a first connecting portion 32 protruding outward, and the first connecting portion 32 can be inserted between the second flange 211b and the panel portion 20, and the first connecting portion 32 and the second flange 211b are detachably connected, so that the lower side of the display bracket 3 can also be connected to the connecting flange 211, so that the connection stability of the display bracket 3 and the flange frame 21 is better, and because the first connecting portion 32 is connected to the side of the second flange 211b away from the bottom shell 1, the first connecting portion 32 will not affect the connection tightness between the second flange 211b and the bottom shell 1, and can make the waterproof performance of the connection between the second flange 211b and the bottom shell 1 better. In addition, since the upper side of the display bracket 3 will not interfere with the flange frame 21, there is no need to set an avoidance structure on either side of the flange frame 21 in the up and down directions, and the first connecting part 32 can be directly inserted between the second flange 211b and the panel part 20.

[0053] At this time, preferably, the first connecting hole 21b is located at the lower side of the corresponding avoidance groove 21a, so that in the process of installing the display bracket 3 to the flange frame 21, the connecting ear 31 can pass through the avoidance groove 21a to enter between the first flange 211a and the panel part 20, and at the same time, the first connecting part 32 is located between the connecting flange 211 and the panel part 20, and then the display bracket 3 is moved downward toward the second flange 211b, so that the connecting ear 31 is located at the corresponding first connecting hole 21b, and the first connecting part 32 can be inserted between the second flange 211b and the panel part 20.

[0054] In one embodiment, the second flange 211b is provided with a second connecting hole 21c, and the first connecting portion 32 is connected to the second flange 211b by a second fastener 23 passing through the second connecting hole 21c, so that the detachable connection between the first connecting portion 32 and the second flange 211b is easy to disassemble and assemble and has good connection stability.

[0055] The second fastener 23 may include but is not limited to bolts, screws, rivets, etc., and the second fastener 23 may be fixedly arranged on the first connection portion 32, or the first connection portion 32 may be provided with a through hole, and the second fastener 23 may pass through the through hole and the second connection hole 21c in sequence to connect the first connection portion 32 with the second flange 211b. When the second fastener 23 includes a threaded member such as a bolt or a screw, the through hole on the first connection portion 32 may be a threaded hole so that the second fastener 23 can be threadedly connected to the first connection portion 32, or the second fastener 23 may also include a nut, so that the nut is threadedly connected to the threaded member, so that the head of the threaded member and the nut are clamped on the two opposite sides of the first connection portion 32 and the connection flange 211.

[0056] When the second fastener 23 partially protrudes from the side of the connecting flange 211 facing the bottom shell 1, in one embodiment, the bottom shell 1 is also provided with an avoidance recess 12 corresponding to the second connecting hole 21c, and the avoidance recess 12 is used to accommodate part of the second fastener 23, so as to avoid the second fastener 23 from interfering with the bottom shell 1 and affecting the tightness of the connection between the bottom shell 1 and the second flange 211b on the one hand, and on the other hand, the second fastener 23 can be accommodated in the avoidance recess 12 so that the second fastener 23 can be aligned with the position of the avoidance recess 12, thereby helping the flange frame 21 to be aligned and connected with the bottom shell 1.

[0057] Please also see Figures 2 to 5 In one embodiment, the bottom shell 1 further comprises a hanging portion 13 located on the upper side of the front opening 1b, the hanging portion 13 comprises a hanging groove 13a with the notch facing upward, the connecting flange 211 may comprise a third flange 211c corresponding to the upper side of the panel portion 20, the third flange 211c partially extends into the hanging groove 13a to be hung on the hanging portion 13, so that the connection method between the third flange 211c and the hanging portion 13 is simple. And since the third flange 211c and the hanging portion 13 are located at the top of the water heater housing 100 when the water heater housing 100 is in use, when water enters the connection between the third flange 211c and the hanging portion 13, the water can flow into the hanging groove 13a and be discharged from the end of the hanging groove 13a, and is not easy to enter the interior of the water heater housing 100, so the waterproof performance of the connection between the third flange 211c and the hanging portion 13 is still good.

[0058] Furthermore, the water heater shell 100 may also include a third fastener (not shown in the figure), and the bottom shell 1 has a bottom 15, which is detachably connected to the face shell assembly 2 or the display bracket 3 through the third fastener, so that the connection between the face shell assembly 2 and the display bracket 3 as a whole and the bottom 15 is more stable.

[0059] In addition, the face shell assembly 2 is connected to the bottom shell 1 by hanging the third flange 211c with the hanging portion 13 at the top, and the face shell assembly 2 or the display bracket 3 is connected to the bottom shell 1 at the bottom 15 by the third fastener. In the process of disassembling and assembling the face shell assembly 2 and the display bracket 3 with the bottom shell 1 as a whole, the operator only needs to tighten or disassemble the third fastener from the bottom 15 of the bottom shell 1 to connect and lock the face shell assembly 2 and the display bracket 3 with the bottom shell 1 as a whole, or to open and separate them. Therefore, such a design can simplify the assembly process of the face shell assembly 2 and the display bracket 3 with the bottom shell 1 as a whole, and at the same time, it can also improve the connection stability of the face shell assembly 2 and the display bracket 3 with the bottom shell 1 as a whole and the waterproofness of the connection.

[0060] Furthermore, during after-sales maintenance, even if the third fastener is removed, the face shell assembly 2 will still be hung on the bottom shell 1, and there will be no risk of the face shell assembly 2 and the display bracket 3 falling off as a whole once the third fastener is removed, making the maintenance process safer.

[0061] Exemplarily, the bottom 15 is provided with a third connecting hole 1c, and the face shell assembly 2 or the display bracket 3 is provided with a fourth connecting hole 24 corresponding to the third connecting hole 1c. The third fastener may be a threaded connector, and the third fastener portion is passed through the corresponding third connecting hole 1c and the fourth connecting hole 24 and connects the bottom 15 with the face shell assembly 2 or the display bracket 3, thereby enabling the face shell assembly 2 and the display bracket 3 to be connected to the bottom 15 of the bottom shell 1 as a whole with good stability.

[0062] In one embodiment, the bracket body 30 is also provided with a second connection portion 33 protruding toward the rear side, the second connection portion 33 partially extends into the inner cavity 1a and corresponds to the bottom 15, and the second connection portion 33 is detachably connected to the bottom 15 via a third fastener. Since the bracket body 30 is located inside the face shell assembly 2, the second connection portion 33 can directly pass through the front opening 1b to extend into the inner cavity 1a, so as to hide the second connection portion 33 inside the water heater shell 100.

[0063] At this time, the second connection portion 33 may be provided with a fourth connection hole 24 as described in the above embodiment.

[0064] For example, when manufacturing the display bracket 3, stamping can be used to bend part of the plate relative to the bracket body 30 to form the second connection part 33, and part of the plate connected to the second connection part 33 can be bent relative to the second connection part 33 to form the first connection part 32, so that the molding process of the first connection part 32 and the second connection part 33 is simple.

[0065] In other embodiments, the flanged frame 21 may be connected to the bottom shell 1 through the connecting portion by additionally connecting the connecting portion on the flanged frame 21 in a manner including but not limited to riveting, welding, and screwing.

[0066] Please combine Figure 6 and Figure 7 As shown, in one embodiment, the water heater housing 100 also includes a decorative part 4, which is located on the lower side of the bottom shell 1. The decorative part 4 is provided with a countersunk hole, and a third fastener is partially passed through the countersunk hole to fasten the bottom 15 and the decorative part 4, and one end of the third fastener is located in the countersunk hole. Therefore, on the one hand, the third fastener can be covered by the decorative part 4, and on the other hand, the decorative part 4, the surface shell assembly 2 and the bottom 15 of the bottom shell 1 can be connected at one time through the third fastener, so that the disassembly and assembly operation of the water heater housing 100 is simple and the steps are few.

[0067] As described in the aforementioned technical solution, the bottom 15 is provided with a third connecting hole 1c, and the face shell assembly 2 or the display bracket 3 is provided with a fourth connecting hole 24 corresponding to the third connecting hole 1c, and the decorative component 4 is provided with a fifth connecting hole 4a corresponding to the third connecting hole 1c, and the fifth connecting hole 4a is the aforementioned countersunk hole, and the third fastener portion is passed through the corresponding fifth connecting hole 4a, the third connecting hole 1c and the fourth connecting hole 24 to connect the decorative component 4 and the bottom 15 with the face shell assembly 2 or the display bracket 3.

[0068] In one embodiment, the lower side of the front opening 1b has a shielding portion 14 extending downward from the bottom surface of the bottom shell 1, and the decorative component 4 is at least partially located on the side of the shielding portion 14 facing away from the surface shell assembly 2, so that at least a portion of the decorative component 4 can be shielded by the shielding portion 14, so that when the user observes the water heater from the side where the surface shell assembly 2 is located, the appearance of the water heater is simpler.

[0069] In one embodiment, the second flange 211b may correspond to abut the shielding portion 14, so that the surface shell assembly 2 can shield the shielding portion 14, so that when the user observes the water heater from the side where the surface shell assembly 2 is located, the appearance of the water heater is simpler.
