Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present disclosure claims priority to Chinese Patent Application No. 2024116598818 entitled “HOT WATER MACHINE HOUSING AND HOT WATER MACHINE” filed with Chinese Patent Office on Nov. 19, 2024, the entire contents of which are incorporated herein by reference as part of the present disclosure.TECHNICAL FIELD

[0002] The present disclosure relates to the technical field of heat pump heating equipment, and specifically to a hot water machine housing and a hot water machine.BACKGROUND ART

[0003] A hot water machine is an efficient heat-energy enhancing and transferring device that works based on the reverse Carnot cycle. It uses a small amount of electrical energy as power, with refrigerant as the medium, to absorb low-grade thermal energy from the air, convert it into usable high-grade thermal energy, and then release the high-grade thermal energy into water that needs heating to produce domestic hot water, which is ultimately delivered to the user via the hot water pipeline.

[0004] Typically, the hot water machine housing is of a rectangular structure, including a top cover and a bottom plate that are opposite and arranged at intervals along an up-down direction; and sidewall panels connecting the top cover and bottom plate. The top cover and sidewall panels are fixedly connected by screws. However, the existing connection structure configured to fix the top cover and the sidewall panel is exposed, making it easy for dust and impurities to enter through the connection positions and also affecting the aesthetics of the hot water machine housing.SUMMARY

[0005] The first objective of the present disclosure is to provide a hot water machine housing to solve the following technical problem that the existing connection structure in the hot water machine housing configured to fix the top cover and the sidewall panel is exposed, which leads to easy entry of dust and impurities and affects aesthetics.

[0006] The hot water machine housing provided in the present disclosure includes a top cover and a bottom plate that are spaced apart and arranged opposite each other in an up-down direction, and a sidewall panel connecting the top cover and the bottom plate. An upper edge of the sidewall panel is provided with a first overlapping edge and a first assembly edge. The first overlapping edge extends approximately in a horizontal direction toward an interior cavity of the hot water machine housing, and the first assembly edge is angled relative to the first overlapping edge. An edge of the top cover is provided with a second overlapping edge and a second assembly edge, the second overlapping edge extends approximately in a horizontal direction toward the interior cavity, and the second assembly edge is angled relative to the second overlapping edge, the second overlapping edge overlaps with the first overlapping edge, the second assembly edge is opposite the first assembly edge, and the second assembly edge is connected with the first assembly edge.

[0007] When the top cover needs to be assembled to a side plate body, the top cover can be mounted to the sidewall panel in a direction of the second overlapping edge toward the interior cavity. When the top cover is positioned on the sidewall panel, the second overlapping edge, arranged at the lower edge of the top cover, overlaps with the first overlapping edge at the upper edge of the sidewall panel. At this point, the second assembly edge of the top cover is opposite the first assembly edge of the sidewall panel in the horizontal direction, and the two are connected in an assembling manner.

[0008] Thus, through the arrangement described above, the hot water machine housing ensures that the first assembly edge and the second assembly edge, which are configured for fixed connection, are positioned in the interior cavity. When a connection structure connects the first assembly edge and the second assembly edge, the connection structure can be hidden within the interior cavity of the hot water machine housing. This effectively improves the issue of the connection structure between the top cover and the sidewall panel being exposed in the prior art, prevents dust and impurities from entering the connection positions, and ensures the aesthetics of the hot water machine housing.

[0009] Furthermore, the overlapping fit between the first overlapping edge and the second overlapping edge supports the top cover during the assembly of the top cover, which eliminates the need for the operator to constantly hold the top cover, thus reducing assembly difficulty. Additionally, the first assembly edge arranged at the first overlapping edge and the second assembly edge arranged at the second overlapping edge can form a labyrinth sealing structure at the connecting seam between the top cover and the sidewall panel, to extend the path from the exterior of the hot water machine housing to the interior cavity, thus further reducing the entry of external impurities.

[0010] Further, the first assembly edge is located on a side of the first overlapping edge facing the interior cavity, and the second assembly edge is located on a side of the second overlapping edge facing the interior cavity. This arrangement, where the first assembly edge and the second assembly edge cooperate beneath the connecting seam of the top cover and the sidewall panel, allows the operation of which the screws connect the first assembly edge and the second assembly edge to be performed below the connecting seam. This provides ample working space, thereby improving assembly efficiency. And / or the first overlapping edge and the first assembly edge are formed by bending an upper edge of the sidewall panel. The arrangement enables the sidewall panel to be an integrated structure, which not only reduces the number of components required to form the sidewall panel but also increases the structural strength at the upper edge of the sidewall panel. And / or the second overlapping edge and the second assembly edge are formed by bending an edge of the top cover. The arrangement enables the top cover to be an integrated structure, which not only reduces the number of components required to form the top cover but also increases the structural strength at the edge of the top cover to suppress the deformation of the top cover.

[0011] Further, the sidewall panel includes a first side panel and a second side panel, which are spaced apart and arranged opposite each other in a left-right direction, and a front panel and a rear panel, which are spaced apart and arranged opposite each other in the front-rear direction. The first side panel, rear panel, and second side panel are sequentially connected to form a structure with a front opening. The first overlapping edge and the first assembly edge are formed on the first side panel, rear panel, and second side panel, and the front panel is connected to the first side panel and the second side panel. This arrangement allows the top cover to be fixedly connected to the first side panel, rear panel, and second side panel along three edges. The connection regions are widely distributed, which ensures the reliability of the connection between the top cover and the sidewall panel. Additionally, by dividing the sidewall panel from the whole into two parts, during the assembly process, the front panel can initially be left unmounted, leaving the front opening in an open state, and then the top cover is assembled to the first side panel, rear panel, and second side panel. At this time, the operator can perform assembly operations directly through the front opening, improving assembly convenience.

[0012] Further, the front panel is snap-fitted to the first side panel and the second side panel. The arrangement of snap-fitting the front panel to the first side panel and the second side panel improves the connection efficiency between the front panel and the first side panel and the second side panel. Furthermore, the snap-fitting arrangement provides positioning during the assembly process of the front panel.

[0013] Further, an edge of the first side panel near the front panel is provided with a first side flange folded toward the interior cavity, an edge of the second side panel near the front panel is provided with a second side flange folded toward the interior cavity, both the first side flange and the second side flange are provided with snap holes, and the front panel is provided with snaps that snap-fit with the snap holes. By providing the snap holes on the first side flange and the second side flange mentioned above, the front panel, after being mounted to the first side panel and the second side panel, forms a cover over the snap holes. This prevents the snap-fit structure between the front panel and the first side panel and the second side panel from being exposed.

[0014] Further, the lower edge of the first side panel is provided with a first flange folded toward the interior cavity approximately in the horizontal direction, and the first flange is provided with a first mounting hole. The lower edge of the second side panel is provided with a second flange folded toward the interior cavity approximately in the horizontal direction, and the second flange is provided with a second mounting hole. On one side of the bottom plate, a first mounting edge folded toward the interior cavity approximately in the horizontal direction is provided, and the first mounting edge is provided with a first bottom plate fixing hole matching the first mounting hole. On the other side of the bottom plate, a second mounting edge folded toward the interior cavity approximately in the horizontal direction is provided, and the second mounting edge is provided with a second bottom plate fixing hole matching the second mounting hole. The first flange is supported on the first mounting edge, and the first mounting hole is opposite the first bottom plate fixing hole. The second flange is supported on the second mounting edge, and the second mounting hole is opposite the second bottom plate fixing hole. This arrangement enables both the connection structures of the bottom plate with the first side panel and the second side panel to be located inside the hot water machine housing, thereby achieving a concealed arrangement of the connection structures of the bottom plate with the first side panel and the second side panel.

[0015] Further, the first mounting edge is bent upward to form a first limiting edge, and the second mounting edge is bent upward to form the second limiting edge. The first flange and the first limiting edge are mated in a limiting manner, and the second flange and the second limiting edge are mated in a limiting manner. The arrangement provides positioning for the sidewall panel during assembly.

[0016] Further, the bottom plate is provided with a first vertical connection edge near the rear panel. The first vertical connection edge is located on the side of the rear panel close to the interior cavity, and the first vertical connection edge is provided with a third bottom plate fixing hole. The first vertical connection edge connects with the rear panel through the third bottom plate fixing hole. The arrangement of the first vertical connection edge mentioned above enables the first vertical connection edge to restrict the forward movement of the rear panel after the bottom plate and the sidewall panel are assembled, thereby achieving forward limiting of the sidewall panel. Simultaneously, the third bottom plate fixing hole, which is arranged on the first vertical connection edge and configured to connect the rear panel, not only achieves fixation of the bottom plate to the sidewall panel at its rear edge but also conceals the fixing structure inside the hot water machine housing, thus avoiding exposure of the connection structure.

[0017] And / or the bottom plate is provided with a second vertical connection edge near the front panel. The second vertical connection edge is located on a side of the front panel near the interior cavity. The second vertical connection edge is provided with a fourth bottom plate fixing hole, and the second vertical connection edge connects with the front panel through the fourth bottom plate fixing hole. The aforementioned arrangement of the second vertical connection edge, which is provided thereon with the fourth bottom plate fixing hole configured to connect the front panel, allows the front panel to be fixed to the bottom plate in addition to being snapped to the first side panel and the second side panel, thereby significantly improving the mounting reliability of the front panel. Moreover, the arrangement position of the connection structure, which is in a relatively lower position, ensures that the connection structure between the front panel and the bottom plate is not visible during the use of the hot water machine. Thus, the concealed design of the connection structure at this position is visually realized.

[0018] Further, the first side panel includes a first plate body and a second plate body arranged sequentially in the front-rear direction. The edge of the first plate body near the second plate body is provided with a first notch and a first intermediate flange folded toward the interior cavity. The edge of the second plate body near the first plate body is provided with a second notch and a second intermediate flange folded toward the interior cavity. The first notch and the second notch are connected to form a piping region configured for making piping extend out of the first side of the hot water machine housing. The first intermediate flange and the second intermediate flange are attached and connected, with the second assembly edge supported by both the first intermediate flange and the second intermediate flange. The arrangement facilitates a piping arrangement and support by using the piping region formed between the first plate body and the second plate body, thereby facilitating the arrangement of the piping on the side. Moreover, by connecting the first plate body and the second plate body using the first intermediate flange and the second intermediate flange described above, it also achieves a concealed design of the connection structure between the first plate body and the second plate body, thus ensuring the external appearance integrity of the first side panel. In addition, the first intermediate flange and the second intermediate flange also provide support to one side of the top cover above, to improve the stress resistance of the first overlapping edge.

[0019] Further, the second side panel includes a third plate body and a fourth plate body arranged sequentially in the front-rear direction. The edge of the third plate body near the fourth plate body is provided with a third notch and a third intermediate flange folded toward the interior cavity. The edge of the fourth plate body near the third plate body is provided with a fourth notch and a fourth intermediate flange folded toward the interior cavity. The third notch and the fourth notch are connected to form a piping region configured for making piping extend out of a second side of the hot water machine housing. The third intermediate flange and the fourth intermediate flange are attached and connected, with the second assembly edge supported by both the third intermediate flange and the fourth intermediate flange. The arrangement facilitates piping arrangement and support by using the piping region formed between the third plate body and the fourth plate body, thereby facilitating the arrangement of the piping on the side. Moreover, by connecting the third plate body and the fourth plate body using the third intermediate flange and the fourth intermediate flange described above, it also achieves a concealed design of the connection structure between the third plate body and the fourth plate body, thus ensuring the external appearance integrity of the second side panel. In addition, the third intermediate flange and the fourth intermediate flange also provide support to the other side of the top cover above, to further improve the stress resistance of the first overlapping edge.

[0020] Further, the first side panel includes a first valve plate. The first valve plate is arranged in a piping region formed by connecting the first notch and the second notch. An edge of the first valve plate near the first plate body and an edge of the first valve plate near the second plate body are each provided with a first half-hole. An edge of the first plate body near the first valve plate and an edge of the second plate body near the first valve plate are each provided with a second half-hole. The first half-hole and the second half-hole are connected to form a first support hole configured for supporting the piping. This arrangement allows the mounting of the piping in the first side panel to be accomplished by snapping into and out of the first half-hole and the second half-hole in a radial direction. There is no need to plug the piping axially into the first support hole, thus making it much less difficult to assemble and disassemble.

[0021] And / or the second side panel further includes a second valve plate. The second valve plate is arranged in a piping region formed by connecting the third notch and the fourth notch. An edge of the second valve plate near the third plate body and an edge of the second valve plate near the fourth plate body are each provided with a third half-hole. An edge of the third plate body near the second valve plate and an edge of the fourth plate body near the second valve plate are each provided with a fourth half-hole. The third half-hole and the fourth half-hole are connected to form a second support hole configured for supporting the piping. This arrangement allows the mounting of the piping in the second side panel to be accomplished by snapping into and out of the third half-hole and the fourth half-hole in a radial direction. There is no need to plug the piping axially into the second support hole, thus making it much less difficult to assemble and disassemble.

[0022] Further, the second plate body, the fourth plate body, and the rear panel are integrally molded structures. This arrangement not only reduces the number of components forming the hot water machine housing, thereby improving assembly efficiency but also enhances the stability of the rear panel at the location where it is connected to the second plate body and the fourth plate body.

[0023] Further, the front panel is provided with reinforcement ribs. This arrangement increases the structural strength of the front panel.

[0024] The second objective of the present disclosure is to provide a hot water machine to solve the following technical problem that in the existing hot water machine housing, the connection structure configured to fix the top cover and sidewall panels is exposed, which leads to easy entry of dust and impurities and affects aesthetics.

[0025] The present disclosure provides a hot water machine, including the electric control box and the hot water machine housing mentioned above. The electric control box is mounted on the position of the front opening. The electric control box is connected to the first side panel, the top cover, and the second side panel. The front panel covers the electric control box. The reinforcement ribs, provided on the front panel, protrude from a surface of the front panel facing the interior cavity. The reinforcement ribs abut against the electric control box.

[0026] By incorporating the aforementioned hot water machine housing into the hot water machine, the hot water machine correspondingly possesses all the advantages of the hot water machine housing, which will not be redundantly elaborated here.

[0027] Additionally, by enabling the reinforcement ribs arranged on the front panel to abut against the electric control box, the positioning of the electric control box is further ensured, thus enhancing the stability of the mounting of the electric control box.BRIEF DESCRIPTION OF DRAWINGS

[0050] To make the above objects, features, and advantages of the present disclosure more apparent and understandable, specific embodiments of the present disclosure are described in detail below in conjunction with the drawings. It should be understood that the specific embodiments described herein are for the sole purpose of explaining the present disclosure and are not intended to limit the present disclosure.

[0051] As shown in FIG. 1, the embodiment provides a hot water machine housing 010, which includes a top cover 100 and a bottom plate 200, which are spaced apart and arranged opposite each other in an up-down direction, and a sidewall panel 300 connecting the top cover 100 and the bottom plate 200.

[0052] As shown in FIG. 4 to FIG. 6, an upper edge of the sidewall panel 300 is provided with a first overlapping edge 301 and a first assembly edge 302. The first overlapping edge 301 extends approximately in a horizontal direction toward an interior cavity 011 of the hot water machine housing 010, and the first assembly edge 302 is angled relative to the first overlapping edge 301. The edge of the top cover 100 is provided with a second overlapping edge 110 and a second assembly edge 120. The second overlapping edge 110 extends approximately in the horizontal direction toward the interior cavity 011, and the second assembly edge 120 is angled relative to the second overlapping edge 110. The second overlapping edge 110 overlaps with the first overlapping edge 301, the second assembly edge 120 is opposite the first assembly edge 302, and the second assembly edge 120 is connected with the first assembly edge 302.

[0053] When the top cover 100 needs to be assembled to a side plate body, the top cover 100 can be mounted to the sidewall panel 300 in a direction of the second overlapping edge 110 toward the interior cavity 011. When the top cover 100 is positioned on the sidewall panel 300, the second overlapping edge 110, arranged at the lower edge of the top cover 100, overlaps with the first overlapping edge 301 at the upper edge of the sidewall panel 300. At this point, the second assembly edge 120 of the top cover 100 is opposite the first assembly edge 302 of the sidewall panel 300 in the horizontal direction, and the two are connected in an assembling manner.

[0054] Thus, through the arrangement described above, the hot water machine housing 010 ensures that the first assembly edge 302 and the second assembly edge 120, which are configured for fixed connection, are positioned in the interior cavity 011. When a connection structure connects the first assembly edge 302 and the second assembly edge 120, the connection structure can be hidden within the interior cavity 011 of the hot water machine housing 010. This effectively improves the issue of the existing connection structure between the top cover 100 and the sidewall panel 300 being exposed, prevents dust and impurities from entering the connection positions, and ensures the aesthetics of the hot water machine housing 010.

[0055] Furthermore, the overlapping fit between the first overlapping edge 301 and the second overlapping edge 110 supports the top cover 100 during the assembly of the top cover 100, which eliminates the need for the operator to constantly hold the top cover 100, thus reducing assembly difficulty. Additionally, the first assembly edge 302 arranged at the first overlapping edge 301 and the second assembly edge 120 arranged at the second overlapping edge 110 can form a labyrinth sealing structure at the connecting seam between the top cover 100 and the sidewall panel 300, to extend the path from the exterior of the hot water machine housing 010 to the interior cavity 011, thus further reducing the entry of external impurities.

[0056] It should be noted that in the embodiment, “approximately in the horizontal direction” includes the case where the direction is horizontal, and it also includes the case where the direction forms an angle with the horizontal direction. The angle mentioned above can range from 0° to 30°. For the two edges that extend approximately in the horizontal direction and fit together, such as the first overlapping edge 301 extending approximately in the horizontal direction and the second overlapping edge 110 extending approximately in the horizontal direction, when both first overlapping edge 301 and the second overlapping edge 110 form an angle with the horizontal direction, it is possible that both the first overlapping edge 301 and the second overlapping edge 110 form an angle with the horizontal plane in the same direction. In other words, the first overlapping edge 301 and the second overlapping edge 110 are parallel to each other. This arrangement ensures a fit between the first overlapping edge 301 and the second overlapping edge 110, thus improving assembly stability.

[0057] As shown in FIG. 5, in the embodiment, a first assembly hole 3021 is provided on the first assembly edge 302, and a second assembly hole 121, corresponding to and used in conjunction with the above first assembly hole 3021, is provided on the second assembly edge 120. By using a threaded connection component to fasten the first assembly hole 3021 and the second assembly hole 121, the first assembly edge 302 and the second assembly edge 120 can be relatively fixed, thereby achieving the objective of fixing the top cover 100 to the sidewall panel 300.

[0058] As shown in FIG. 4 and FIG. 5, in the embodiment, the first overlapping edge 301 and the first assembly edge 302 are formed by bending the upper edge of the sidewall panel 300.

[0059] This forming method for the first overlapping edge 301 and the first assembly edge 302 enables the sidewall panel 300 to be an integrated structure, which not only reduces the number of components required to form the sidewall panel 300 but also increases the structural strength at the upper edge of the sidewall panel 300.

[0060] Similarly, as shown in FIG. 4 and FIG. 5, in the embodiment, the second overlapping edge 110 and the second assembly edge 120 are formed by bending the edge of the top cover 100.

[0061] This forming method for the second overlapping edge 110 and the second assembly edge 120 enables the top cover 100 to be an integrated structure, which not only reduces the number of components required to form the top cover 100 but also increases the structural strength at the edge of the top cover 100 to suppress deformation of the top cover 100.

[0062] As shown in FIG. 4 and FIG. 5, in the embodiment, the first assembly edge 302 is located on the side of the first overlapping edge 301 facing the interior cavity 011, and the second assembly edge 120 is located on the side of the second overlapping edge 110 facing the interior cavity 011. That is to say, the first assembly edge 302 is formed by bending downward from the first overlapping edge 301, and the second assembly edge 120 is formed by bending downward from the second overlapping edge 110.

[0063] This arrangement, where the first assembly edge 302 and the second assembly edge 120 cooperate beneath the connecting seam of the top cover 100 and the sidewall panel 300, allows the operation of which the screws connect the first assembly edge 302 and the second assembly edge 120 to be performed below the connecting seam. This provides ample working space, thereby improving assembly efficiency.

[0064] As shown in FIG. 2 and FIG. 3, the sidewall panel 300 can include a first side panel 310 and a second side panel 320, which are spaced apart and arranged opposite each other in a left-right direction, and a front panel 330 and a rear panel 340, which are spaced apart and arranged opposite each other in the front-rear direction. The first side panel 310, rear panel 340, and second side panel 320 are sequentially connected to form a -shaped structure with a front opening. The first overlapping edge 301 and the first assembly edge 302 are formed on the first side panel 310, rear panel 340, and second side panel 320, and the front panel 330 is connected to the first side panel 310 and the second side panel 320.

[0065] This arrangement allows the top cover 100 to be fixedly connected to the first side panel 310, rear panel 340, and second side panel 320 along three edges. The connection regions are widely distributed, which ensures the reliability of the connection between the top cover 100 and the sidewall panel 300. Additionally, by dividing the sidewall panel 300 from the whole into two parts, during the assembly process, the front panel 330 can initially be left unmounted, leaving the front opening in an open state, and then the top cover 100 is assembled to the first side panel 310, rear panel 340, and second side panel 320. At this time, the operator can perform assembly operations directly through the front opening, improving assembly convenience.

[0066] In the embodiment, the front panel 330 is snap-fitted to the first side panel 310 and the second side panel 320.

[0067] The arrangement of snap-fitting the front panel 330 to the first side panel 310 and the second side panel 320 improves the connection efficiency between the front panel 330 and the first side panel 310 and second side panel 320. Furthermore, the snap-fitting arrangement provides positioning during the assembly process of the front panel 330.

[0068] As shown in FIG. 2 and FIG. 3, in the embodiment, the edge of the first side panel 310 near the front panel 330 is provided with a first side flange 311 folded toward the interior cavity 011, and the edge of the second side panel 320 near the front panel 330 is provided with a second side flange 321 folded toward the interior cavity 011. Both the first side flange 311 and the second side flange 321 are provided with snap holes 350, and the front panel 330 is provided with snaps (not shown in the figures) that snap-fit with the snap holes 350.

[0069] By providing the snap holes 350 on the first side flange 311 and the second side flange 321 mentioned above, the front panel 330, after being mounted to the first side panel 310 and the second side panel 320, forms a cover over the snap holes 350. This prevents the snap-fit structure between the front panel 330 and the first side panel 310 and the second side panel 320 from being exposed.

[0070] Additionally, by providing the snap holes 350 on the first side flange 311 and the second side flange 321, on the one hand, the manufacturing difficulty of the first side panel 310 and the second side panel 320 is reduced; and on the other hand, after the front panel 330 is removed, both sides of the front opening remain relatively flat without protruding structures.

[0071] Referring to FIGS. 7 and 8, in the embodiment, the lower edge of the first side panel 310 is provided with a first flange 312 folded toward the interior cavity 011 approximately in the horizontal direction, and the first flange 312 is provided with a first mounting hole 3121. The lower edge of the second side panel 320 is provided with a second flange 322 folded toward the interior cavity 011 approximately in the horizontal direction, and the second flange 322 is provided with a second mounting hole 3221. On one side of the bottom plate 200, a first mounting edge 210 folded toward the interior cavity 011 approximately in the horizontal direction is provided, and the first mounting edge 210 is provided with a first bottom plate fixing hole 211 matching the first mounting hole 3121. On the other side of the bottom plate 200, a second mounting edge 220 folded toward the interior cavity 011 approximately in the horizontal direction is provided, and the second mounting edge 220 is provided with a second bottom plate fixing hole 221 matching the second mounting hole 3221. The first flange 312 is supported on the first mounting edge 210, and the first mounting hole 3121 is opposite the first bottom plate fixing hole 211. The second flange 322 is supported on the second mounting edge 220, and the second mounting hole 3221 is opposite the second bottom plate fixing hole 221.

[0072] When assembling the bottom plate 200, the bottom plate 200 can be placed below the interior cavity 011. The bottom plate 200 and the sidewall panel 300 are then moved toward each other in the up-down direction to place the first flange 312 arranged on the lower edge of the first side panel 310 onto the first mounting edge 210 on one side of the bottom plate 200, and to place the second flange 322 arranged on the lower edge of the second side panel 320 onto the second mounting edge 220 on the other side of the bottom plate 200. At this point, the first mounting hole 3121 arranged on the first flange 312 is aligned with the first bottom plate fixing hole 211 arranged on the first mounting edge 210, and the second mounting hole 3221 arranged on the second flange 322 is aligned with the second bottom plate fixing hole 221 arranged on the second mounting edge 220. Screws can then be used to fasten the first mounting hole 3121 to the first bottom plate fixing hole 211, and to fasten the second mounting hole 3221 to the second bottom plate fixing hole 221. Thus, the bottom plate 200 is fixed relative to the sidewall panel 300.

[0073] This arrangement enables both the connection structures of the bottom plate 200 with the first side panel 310 and the second side panel 320 to be located inside the hot water machine housing 010, thereby achieving a concealed arrangement of the connection structures of the bottom plate 200 with the first side panel 310 and the second side panel 320. The arrangement of the first mounting edge 210 and the second mounting edge 220 provides a basis for the arrangement of the first bottom plate fixing hole 211 and the second bottom plate fixing hole 221. Moreover, it is also possible to utilize the first mounting edge 210 and the second mounting edge 220 to support the sidewall panel 300 when the sidewall panel 300 is connected and fixed to the bottom plate 200. This enables operators to fix the sidewall panel 300 without holding it manually, thereby reducing assembly difficulty.

[0074] Referring to FIGS. 7 and 8, in the embodiment, the first mounting edge 210 is bent upward to form a first limiting edge 230, and the second mounting edge 220 is bent upward to form a second limiting edge 240. The first flange 312 and the first limiting edge 230 are mated in a limiting manner, and the second flange 322 and the second limiting edge 240 are mated in a limiting manner.

[0075] The arrangement of the first limiting edge 230 and the second limiting edge 240 mentioned above, on the one hand, provides positioning for the sidewall panel 300 during assembly; and on the other hand, it is possible to realize the restriction of the sidewall panel 300 along the left-right direction after assembly, thereby preventing relative sliding between the sidewall panel 300 and the bottom plate 200 in the left-right direction.

[0076] Referring to FIG. 7 and in conjunction with FIGS. 9 and 10, in the embodiment, the bottom plate 200 is provided with a first vertical connection edge 250 near the rear panel 340. The first vertical connection edge 250 is located on the side of the rear panel 340 close to the interior cavity 011, and the first vertical connection edge 250 is provided with a third bottom plate fixing hole 251. The first vertical connection edge 250 connects with the rear panel 340 through the third bottom plate fixing hole 251.

[0077] The arrangement of the first vertical connection edge 250 mentioned above enables the first vertical connection edge 250 to restrict the forward movement of the rear panel 340 after the bottom plate 200 and the sidewall panel 300 are assembled, thereby achieving forward limiting of the sidewall panel 300. Simultaneously, the third bottom plate fixing hole 251, which is arranged on the first vertical connection edge 250 and configured to connect the rear panel 340, not only achieves fixation of the bottom plate 200 to the sidewall panel 300 at its rear edge but also conceals the fixing structure inside the hot water machine housing 010, thus avoiding exposure of the connection structure.

[0078] Referring to FIGS. 7 to 10, and in conjunction with FIGS. 11 and 13, in the embodiment, the bottom plate 200 is provided with a second vertical connection edge 260 near the front panel 330. The second vertical connection edge 260 is located on the side of the front panel 330 close to the interior cavity 011, and the second vertical connection edge 260 is provided with a fourth bottom plate fixing hole 261. The second vertical connection edge 260 connects with the front panel 330 through the fourth bottom plate fixing hole 261.

[0079] The aforementioned arrangement of the second vertical connection edge 260, which is provided thereon with the fourth bottom plate fixing hole 261 configured to connect the front panel 330, allows the front panel 330 to be fixed to the bottom plate 200 in addition to being snapped to the first side panel 310 and the second side panel 320, thereby significantly improving the mounting reliability of the front panel 330. Moreover, the arrangement position of the connection structure, which is in a relatively lower position, ensures that the connection structure between the front panel 330 and the bottom plate 200 is not visible during the use of the hot water machine. Thus, the concealed design of the connection structure at this position is visually realized.

[0080] Specifically, the front panel 330 and the second vertical connection edge 260 can be connected by screws.

[0081] Referring to FIG. 9, in the embodiment, the bottom plate 200 is provided with a drainage hole 270 at a plate body and a drainage connector 280 on a side. This arrangement enables the drainage hole 270 or the drainage connector 280 to be opened as needed during the actual use of the hot water machine housing 010 to discharge condensate collected by the bottom plate 200.

[0082] Referring to FIG. 9, in the embodiment, the bottom plate 200 is provided with bottom corners 290. The bottom corners 290 enable the mounting and fixation of the hot water machine.

[0083] Referring to FIGS. 2 and 3, in the embodiment, the first side panel 310 includes a first plate body 313 and a second plate body 314 arranged sequentially in the front-rear direction. The edge of the first plate body 313 near the second plate body 314 is provided with a first notch and a first intermediate flange 315 folded toward the interior cavity 011. The edge of the second plate body 314 near the first plate body 313 is provided with a second notch and a second intermediate flange 316 folded toward the interior cavity 011. The first notch and the second notch are connected to form a piping region configured for making piping extend out of the first side of the hot water machine housing 010. The first intermediate flange 315 and the second intermediate flange 316 are attached and connected, with the second assembly edge 120 supported by both the first intermediate flange 315 and the second intermediate flange 316.

[0084] The arrangement of the first side panel 310 facilitates piping arrangement and support by using the piping region formed between the first plate body 313 and the second plate body 314, thereby facilitating the arrangement of the piping on the side. Moreover, by connecting the first plate body 313 and the second plate body 314 using the first intermediate flange 315 and the second intermediate flange 316 described above, it also achieves a concealed design of the connection structure between the first plate body 313 and the second plate body 314, thus ensuring the external appearance integrity of the first side panel 310. In addition, the first intermediate flange 315 and the second intermediate flange 316 also provide support to one side of the top cover 100 above, to improve the stress resistance of the first overlapping edge 301.

[0085] Referring to FIGS. 2 and 3, in the embodiment, similarly, the second side panel 320 includes a third plate body 323 and a fourth plate body 324 arranged sequentially in the front-rear direction. The edge of the third plate body 323 near the fourth plate body 324 is provided with a third notch and a third intermediate flange 325 folded toward the interior cavity 011. The edge of the fourth plate body 324 near the third plate body 323 is provided with a fourth notch and a fourth intermediate flange 326 folded toward the interior cavity 011. The third notch and the fourth notch are connected to form a piping region configured for making piping extend out of the second side of the hot water machine housing 010. The third intermediate flange 325 and the fourth intermediate flange 326 are attached and connected, with the second assembly edge 120 supported by both the third intermediate flange 325 and the fourth intermediate flange 326.

[0086] The arrangement of the second side panel 320 facilitates piping arrangement and support by using the piping region formed between the third plate body 323 and the fourth plate body 324, thereby facilitating the arrangement of the piping on the side. Moreover, by connecting the third plate body 323 and the fourth plate body 324 using the third intermediate flange 325 and the fourth intermediate flange 326 described above, it also achieves a concealed design of the connection structure between the third plate body 323 and the fourth plate body 324, thus ensuring the external appearance integrity of the second side panel 320. In addition, the third intermediate flange 325 and the fourth intermediate flange 326 also provide support to the other side of the top cover 100 above, to further improve the stress resistance of the first overlapping edge 301.

[0087] Referring to FIGS. 2 and 3, in the embodiment, the first side panel 310 can further include a first valve plate 317. The first valve plate 317 is arranged in the piping region formed by connecting the first notch and the second notch. The edge of the first valve plate 317 near the first plate body 313 and the edge of the first valve plate 317 near the second plate body 314 are each provided with a first half-hole 3171. The edge of the first plate body 313 near the first valve plate 317 and the edge of the second plate body 314 near the first valve plate 317 are each provided with a second half-hole 318. The first half-hole 3171 and the second half-hole 318 are connected to form a first support hole configured for supporting the piping.

[0088] This arrangement makes it possible, when it is necessary to mount the piping in the first side panel 310, to first fix the second plate body 314, insert the piping into the second half-hole 318 of the second plate body 314, and then, mount the first valve plate 317 onto the second plate body 314, and align the first half-hole 3171 arranged on the first valve plate 317 with the above second half-hole 318 to form the first support hole configured for supporting the piping. Similarly, as required by the piping arrangement, the piping can be inserted by the first half-hole 3171 on the other side of the first valve plate 317 after the mounting of the first valve plate 317. Then, the first plate body 313 is mounted on the first valve plate 317, and the second half-hole 318 arranged on the first plate body 313 is aligned with the above first half-hole 3171 to form the first support hole configured for supporting the piping.

[0089] This arrangement allows the mounting of the piping in the first side panel 310 to be accomplished by snapping into and out of the first half-hole 3171 and the second half-hole 318 in a radial direction. There is no need to plug the piping axially into the first support hole, thus making it much less difficult to assemble and disassemble.

[0090] Referring to FIGS. 2 and 3, in the embodiment, the second side panel 320 can further include a second valve plate 327. The second valve plate 327 is arranged in the piping region formed by connecting the third notch and the fourth notch. The edge of the second valve plate 327 near the third plate body 323 and the edge of the second valve plate 327 near the fourth plate body 324 are each provided with a third half-hole 3271. The edge of the third plate body 323 near the second valve plate 327 and the edge of the fourth plate body 324 near the second valve plate 327 are each provided with a fourth half-hole 328. The third half-hole 3271 and the fourth half-hole 328 are connected to form a second support hole configured for supporting the piping.

[0091] This arrangement makes it possible, when it is necessary to mount the piping in the second side panel 320, to first fix the fourth plate body 324, insert the piping into the fourth half-hole 328 of the fourth plate body 324, and then, mount the second valve plate 327 onto the fourth plate body 324, and align the third half-hole 3271 arranged on the second valve plate 327 with the above fourth half-hole 328 to form the second support hole configured for supporting the piping. Similarly, as required by the piping arrangement, the piping can be inserted by the third half-hole 3271 on the other side of the second valve plate 327 after the mounting of the second valve plate 327. Then, the third plate body 323 is mounted on the second valve plate 327, and the fourth half-hole 328 arranged on the third plate body 323 is aligned with the above third half-hole 3271 to form the second support hole configured for supporting the piping.

[0092] This arrangement allows the mounting of the piping in the second side panel 320 to be accomplished by snapping into and out of the third half-hole 3271 and the fourth half-hole 328 in a radial direction. There is no need to plug the piping axially into the second support hole, thus making it much less difficult to assemble and disassemble.

[0093] Referring to FIG. 2, in the embodiment, the second valve plate 327 is provided with an insertion block 3272, and the fourth plate body 324 is provided with an insertion hole 3241.

The connection structure between the first valve plate 317 and the second plate body 314 is similar to the above-mentioned connection structure between the second valve plate 327 and the fourth plate body 324, and therefore will not be described redundantly.

[0094] Referring further to FIG. 2, in the embodiment, the edges of the first plate body 313 and the first valve plate 317 adjacent to each other are each provided with a flange, thus enabling the first plate body 313 and the first valve plate 317 to be fixedly connected through the flange. Similarly, the edges of the third plate body 323 and the second valve plate 327 adjacent to each other are each provided with a flange, thus enabling the third plate body 323 and the second valve plate 327 to be fixedly connected through the flange. This arrangement ensures that the connection structure between the first plate body 313 and the first valve plate 317, and the connection structure between the third plate body 323 and the second valve plate 327, are concealed designs.

[0095] Referring further to FIG. 2, in the embodiment, the second plate body 314, the fourth plate body 324, and the rear panel 340 are integrally molded structures.

[0096] This arrangement not only reduces the number of components forming the hot water machine housing 010, thereby improving assembly efficiency but also enhances the stability of the rear panel 340 at the location where it is connected to the second plate body 314 and the fourth plate body 324.

[0097] Referring to FIGS. 1, 12, and 13, in the embodiment, the front panel 330 is provided with reinforcement ribs 331. This arrangement increases the structural strength of the front panel 330.

The front panel 330 covers the electric control box 020. The reinforcement ribs 331, provided on the front panel 330, protrude from the surface of the front panel 330 facing the interior cavity 011, and the reinforcement ribs 331 abut against the electric control box 020.

[0099] By incorporating the aforementioned hot water machine housing 010 into the hot water machine, the hot water machine correspondingly possesses all the advantages of the hot water machine housing 010, which will not be redundantly elaborated here.

[0100] Additionally, by enabling the reinforcement ribs 331 arranged on the front panel 330 to abut against the electric control box 020, the positioning of the electric control box 020 is further ensured, thus enhancing the stability of the mounting of the electric control box 020.

[0101] A cushioning pad can be arranged between the reinforcement ribs 331 and the electric control box 020 to isolate vibration transmission between the front panel 330 and the electric control box 020.

[0102] Referring to FIGS. 11 and 12, in the embodiment, the top cover 100 can also be provided with hanging lugs 130, thus allowing the electric control box 020 of the hot water machine to be hung on the top cover 100 via the hanging lugs 130, and the left and right sides of the electric control box 020 are fixed to the first side panel 310 and the second side panel 320 using screws.

[0103] The arrangement of the hanging lugs 130 mentioned above enables the electric control box 020 to be temporarily hung on the hot water machine housing 010 after the screws configured to fix the electric control box 020 are removed, thereby preventing it from falling during after-sales disassembly.
