[0006] The rear plate, together with the front shell, forms an annular circumferential wall. The two ends of the rear plate are hooked onto the inner sides of the two side plates to achieve the connection between the rear plate and the front shell.

[0007] Beneficial effects: The entire front shell is U-shaped, and the rear panel is hooked to the inside of the two side panels, thus concealing the connection between the rear panel and the front shell within the front shell. This improves the integrity, consistency, and aesthetics of the product from the side and rear views. Furthermore, the hook-and-loop connection between the rear panel and the front shell not only ensures high assembly efficiency and convenient disassembly, but also avoids the aesthetic problems associated with screw connections, such as exposed screws. This effectively solves the problems of low assembly efficiency and unsightly appearance in existing shell technologies.

[0008] In one optional embodiment, hook portions are provided on the inner sides of both ends of the rear plate, and hook mating portions are provided on the inner sides of both side plates, with the hook portions hooking onto the hook mating portions.

[0009] Beneficial effects: By setting the hook and hook mating parts on the inside of the back panel and the two side panels respectively, the connection between the back panel and the front shell is hidden inside the front shell, effectively avoiding the problem of the connection being exposed and affecting the product's aesthetics and integrity.

[0010] In one optional embodiment, the side panel and the front panel are integrally formed, and the front shell further includes:

[0011] The two side plates are bent and extended from the ends away from the front plate in a direction that brings them closer to each other to form the bent wall. The hook engagement part is provided on the inner side of the end of the bent wall.

[0012] Beneficial effects: By using a one-piece molding process for the side panels and front panel, assembly steps can be eliminated, resulting in better overall integrity and aesthetics of the front shell. Furthermore, the front shell employs a double-bent wall design, with the rear panel connected to the inside of these walls.

[0019] The air vent grille is fastened to the top of the annular circumferential wall.

[0020] Beneficial effects: The air vent grille is connected to the annular circumferential wall by a snap-fit ​​method, eliminating the need for screws and making disassembly and assembly more convenient and quick.

[0021] In one alternative embodiment, both the top inner sides of the front shell and the rear panel are provided with flanges, and the flanges are provided with snap holes.

[0022] The air vent grille is equipped with clips that snap into the holes.

[0023] Beneficial effects: The flanges set on the inner side of the front shell and the rear panel not only support the air vent grille, but also fix the air vent grille in the annular circumferential wall by snapping the buckles on the flanges into the snap holes. The connection is reliable and stable, and the disassembly and assembly are more convenient and quick.

[0024] In one optional embodiment, a limiting hole is also provided on the flange, and a limiting rib is provided on the air outlet grille;

[0025] The limiting rib is inserted into the limiting hole and held against the edge of the limiting hole to prevent the buckle from disengaging from the hole.

[0026] Beneficial effects: The counter-attacking action of the limiting ribs and limiting holes ensures that the buckle and the buckle are tightly engaged, preventing the buckle from shifting and disengaging from the buckle when the machine shakes, thus avoiding engagement failure.

[0027] In one alternative implementation, the housing assembly further includes:

[0028] The base is connected to the bottom of the annular circumferential wall via a connector. The base and the annular circumferential wall are connected to form a stepped structure, and the connector is located on the stepped surface.

[0029] Beneficial effects: The base and the annular circumferential wall are connected by connectors, forming a stepped structure that is wider at the top and narrower at the bottom. The connectors are located on the stepped surface and are hidden by the wrapping effect of the front shell and the rear panel. This achieves a connector-free design on the five main appearance surfaces (front, back, left, right, and top), leaving the connectors on the bottom surface of the secondary appearance surfaces. This makes the overall appearance of the entire shell assembly more integrated and aesthetically pleasing, further enhancing the product's aesthetics.

[0030] In one alternative implementation, the base includes:

[0031] The seat body has a cavity with a top opening inside, and the cross-sectional area of ​​the seat body is smaller than the cross-sectional area of ​​the annular peripheral wall.

[0032] The flanged part is provided on the top outer periphery of the base part, and the connecting fold is provided on the bottom inner periphery of the annular circumferential wall. The flanged part is connected to the connecting fold.

[0033] Beneficial effects: The flange fits snugly against the bottom of the connecting fold, and is then fixed in place by a connector. The flange and connecting fold make it easier to connect the base and the annular wall. Furthermore, the connecting fold extends inward from the bottom edge of the annular wall, ensuring the connection structure between the base and the annular wall is located on the inner circumference of the annular wall, preventing the connection structure from protruding and affecting the overall aesthetics.

[0034] In one optional embodiment, the flange and the connecting fold are provided with multiple sets of connecting holes at circumferential intervals, and the connectors are multiple, with each connector corresponding to one of the multiple sets of connecting holes.

[0035] Beneficial effects: By using multiple sets of connecting holes spaced apart along the circumference and connecting these holes one-to-one with multiple connectors, the stability and reliability of the connection between the base and the front shell and rear plate can be further improved.

[0063] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0064] The following is combined Figures 1 to 15 The following describes embodiments of the present invention.

[0065] According to embodiments of the present invention, on the one hand, such as Figures 1 to 4 As shown, this utility model provides a housing assembly, including a front shell 1 and a rear plate 2, including a front plate 11 and two side plates 12 located on both sides of the front plate 11; the rear plate 2 and the front shell 1 enclose to form an annular peripheral wall 100, and the two ends of the rear plate 2 are hooked to the inner sides of the two side plates 12 to realize the connection between the rear plate 2 and the front shell 1.

[0066] In the above embodiment, the entire front shell is U-shaped, and the rear panel hooks are located on the inner sides of the two side panels 12, so that the connection between the rear panel 2 and the front shell 1 is hidden inside the front shell 1, improving the integrity, consistency, and aesthetics of the product from the side and rear views. Furthermore, the connection between the rear panel 2 and the front shell 1 via hooks not only ensures high assembly efficiency and convenient disassembly, but also avoids the problem of exposed screws affecting aesthetics, effectively solving the problems of low assembly efficiency and unsightly appearance of the shells in the prior art.

[0067] In some embodiments, hook portions 21 are provided on the inner sides of both ends of the rear plate 2, and hook mating portions 131 are provided on the inner sides of both side plates 12. The hook portions 21 are hooked onto the hook mating portions 131. By providing the hook portions and hook mating portions on the inner sides of the rear plate and the two side plates respectively, the connection between the rear plate and the front shell is hidden inside the front shell, effectively avoiding the problem of the connection being exposed and affecting the aesthetics and integrity of the product.

[0068] Specifically, in this embodiment, the side plate 12 and the front plate 11 are integrally formed. By adopting an integral forming method, the assembly steps of the side plate and the front plate can be eliminated, making the overall integrity and aesthetics of the front shell 1 better. Preferably, the front shell 1 is an integral sheet metal part, which can be formed by stamping and bending processes. The two side plates 12 are set on opposite sides of the front plate 11. The two side plates 12 can be parallel, or the distance between the two side plates 12 can gradually increase or decrease from the front plate 11 to the rear plate 2. This embodiment does not limit this.

[0069] Furthermore, one of the hook portion 21 and the hook mating portion 131 may be a hook and the other may be a hook groove 1312, or one may be a hook and the other may be a plate. This embodiment does not limit this.

[0070] In some embodiments, the front shell 1 further includes a bent wall 13, wherein the ends of the two side plates 12 away from the front plate 11 are bent and extended toward each other to form the bent wall 13, and the hook-and-loop engagement portion 131 is disposed on the inner side of the end of the bent wall 13. By adopting the design of two bent walls 13 and connecting the rear plate 2 to the inner side of the two bent walls 13, the connection part between the rear plate 2 and the front shell 1 is hidden inside the front shell 1, which can further improve the integrity, consistency and aesthetics of the product from the side and rear views.

[0071] Furthermore, in this embodiment, the hook engagement part 131 is provided on the inner wall of the bent wall 13. When the hook of the rear plate 2 is assembled onto the front shell 1, the outer wall of the rear plate 2 and the outer wall of the bent wall 13 are located on the same plane, forming a flat and integrated rear wall, which is more aesthetically pleasing.

[0072] In some embodiments, the hook engagement part 131 includes a hook plate 1311 fixedly disposed on the inner side of the bent wall 13 and a hook groove 1312 formed on the hook plate 1311; the hook part 21 includes a hook fixedly disposed on the inner wall of the rear plate 2, and the hook engages in the hook groove 1312.

[0073] In the above embodiment, the connection between the rear plate 2 and the front shell 1 is achieved by the hook provided on the rear plate 2 and the hook groove 1312 provided on the hook plate 1311 on the inner side of the bent wall 13 through the hook insertion and engagement into the hook groove 1312. Compared with the hook engagement form of only using the hook and hook plate 1311, the hook groove 1312 can circumferentially limit the hook inserted therein, further improving the stability and reliability of the connection between the rear plate 2 and the front shell 1, making the rear plate 2 less likely to loosen and fall off.

[0074] Specifically, the hook plate 1311 is a plate-like structure with an L-shaped cross-section. The side of the bent wall 13 extends a certain distance towards the front plate 11 to form a first plate. The first plate continues to extend towards the opposite bent wall 13 to form a second plate. The first plate is parallel to the side plate 12, and the second plate is parallel to the front plate 11. The hook groove 1312 is formed on the second plate. Optionally, the hook groove 1312 is a strip-shaped hole formed on the second plate along the length direction of the hook plate 1311.

[0075] Furthermore, the hook is an H-shaped hook fixedly installed on the inner wall of the rear plate 2. During assembly, the H-shaped hook is placed in the hook groove 1312 and below the rear plate 2, so that the grout inside the H-shaped hook overlaps with the bottom edge of the hook groove 1312, realizing the hook engagement between the rear plate 2 and the front plate 11. At the same time, the two sides of the hook groove 1312 can limit the hook in the left and right directions. The H-shaped hook includes a vertical support rib and a hook rib fixedly installed on one side of the support rib. The hook rib is similar to the shape of a "7". The length of the hook groove 1312 is greater than the length of the hook rib, and the gap between the hook rib and the support rib is greater than the thickness of the hook plate 1311.

[0076] In some embodiments, the hook groove 1312 is provided in multiple sets, and the multiple sets of hook grooves 1312 are spaced apart along the height direction of the front shell 1, and the hooks are provided in multiple sets accordingly.

[0077] In the above embodiments, by setting multiple sets of hook grooves 1312 and multiple sets of hooks, the multiple sets of hook grooves 1312 and multiple sets of hooks are matched one-to-one, which can further improve the stability of the connection between the rear plate 2 and the front shell 1.

[0078] Preferably, there are two sets of hook grooves 1312 and hooks, with the two sets of hook grooves 1312 spaced apart at the upper and lower ends of the hook plate 1311, and the two sets of hooks correspondingly spaced at the upper and lower ends of the rear plate 2.

[0079] In some embodiments, such as Figures 5 to 11 As shown, the housing assembly also includes an air outlet grille 3, which is fastened to the top of the annular peripheral wall 100.

[0080] In the above embodiment, the air outlet grille 3 is connected to the annular peripheral wall 100 by a snap-fit ​​method, which eliminates the need for screws and makes disassembly and assembly more convenient and quick.

[0081] In some embodiments, the top inner sides of the front shell 1 and the rear plate 2 are provided with flanges 101, and the flanges 101 are provided with snap holes 102; the air outlet grille 3 is provided with buckles 31, which are snapped into the snap holes 102.

[0082] In the above embodiment, the flange 101 provided on the inner side of the front shell 1 and the rear plate 2 can not only support the air outlet grille 3, but also fix the air outlet grille 3 in the annular peripheral wall 100 by engaging the buckle 31 on the air outlet grille 3 in the buckle hole 102 provided on the flange 101. The connection is reliable and stable, and the disassembly and assembly are more convenient and quick.

[0083] Specifically, the front panel 11, the side panel 12 and the rear panel 2 are all provided with flanges 101, and each flange 101 is provided with one or more locking holes 102. Preferably, the entire housing assembly is a cuboid structure, with the front panel 11 and the rear panel 2 extending along the length direction of the housing assembly and the side panel 12 extending along the width direction of the housing assembly. The flanges 101 on the front panel 11 and the rear panel 2 are provided with multiple locking holes 102 at intervals.

[0084] Furthermore, the vertical distance between the flange 101 and the top edge of the annular peripheral wall 100 is greater than the thickness of the air outlet grille 3. The top surface of the flange 101 and the inner peripheral surface of the annular peripheral wall 100 enclose an installation space for accommodating the air outlet grille 3. The entire air outlet grille 3 is embedded in this installation space. This design enables the air outlet grille 3 to be hidden, and the user cannot see the air outlet grille 3 from the outer peripheral side, which is more aesthetically pleasing.

[0085] In some embodiments, the flange 101 is further provided with a limiting hole 103, and the air outlet grille 3 is provided with a limiting rib 32; the limiting rib 32 is inserted into the limiting hole 103 and held against the edge of the limiting hole 103 to prevent the buckle 31 from disengaging from the buckle hole 102.

[0086] In the above embodiment, the limiting rib 32 and the limiting hole 103 abut against each other, so that the buckle 31 and the buckle hole 102 can be kept in a tight snap-fit ​​state, so as to prevent the buckle 31 from displacing and disengaging from the buckle hole 102 when the whole machine shakes, thus preventing the snap-fit ​​failure.

[0087] Specifically, the locking hole 102 includes a locking edge, onto which the buckle 31 is engaged. The limiting hole 103 includes a limiting edge, which is positioned opposite to the locking edge. A limiting rib 32 abuts against the limiting edge, applying a force to the air outlet grille 3 to drive the buckle 31 toward the locking edge, thereby ensuring that the buckle 31 is tightly engaged with the locking edge and will not disengage. Further, the limiting rib 32 includes a plate-shaped body 321 and a supporting portion fixedly disposed on the side of the plate-shaped body 321 near the limiting edge. The supporting rib 322 includes an inclined guide edge and a straight supporting edge, the supporting edge being parallel to the plane of the plate-shaped body 321. The guide edge guides the limiting rib 32 into the limiting hole 103, and the supporting edge abuts against the limiting edge. Preferably, there are two supporting ribs 322 spaced apart, and a reinforcing rib is provided on the other side of the plate-shaped body 321.

[0088] In some embodiments, such as Figures 11 to 15 As shown, the housing assembly also includes a base 4, the top of which is connected to the bottom of the annular peripheral wall 100 via a connector 43. The base 4 and the annular peripheral wall 100 are connected to form a stepped structure, and the connector 43 is located on the stepped surface.

[0089] In the above embodiment, the base 4 and the annular peripheral wall 100 are connected by a connector 43, and the entire shell assembly forms a stepped structure that is wider at the top and narrower at the bottom. The connector 43 is located on the stepped surface, and the connector 43 is hidden by the wrapping effect of the front shell 1 and the rear plate 2. This achieves a design without connector 43 on the five main appearance surfaces (front, back, left, right, and top), leaving the connector 43 on the bottom surface of the secondary appearance surface. This makes the overall appearance and aesthetics of the entire shell assembly better, and further improves the aesthetics of the product.

[0090] It should be explained that, in this embodiment, the connector 43 includes, but is limited to, screws and rivets; preferably, the connector 43 is a screw. The cross-sectional area of ​​the annular peripheral wall 100 is larger than the cross-sectional area of ​​the base 4, and the base 4 and the annular peripheral wall 100 are connected to form a stepped cuboid structure that is wider at the top and narrower at the bottom. The base 4 includes a bottom wall and a base peripheral wall disposed around the bottom wall. The distance from the base peripheral wall to the center of the base 4 is smaller than the distance from the annular peripheral wall 100 to the center of the annular peripheral wall 100. In this embodiment, the term "cross-section" refers to a section perpendicular to the height direction of the outer casing assembly.

[0091] In some embodiments, the base 4 includes a seat portion 41, the seat portion 41 having a cavity with a top opening, the cross-sectional area of ​​the seat portion 41 being smaller than the cross-sectional area of ​​the annular peripheral wall 100; the base 4 includes a flange portion 42, the top outer periphery of the seat portion 41 is provided with a flange portion 42, the bottom inner periphery of the annular peripheral wall 100 is provided with a connecting folded edge 104, and the flange portion 42 is connected to the connecting folded edge 104.

[0092] In the above embodiment, the flange 101 and the connecting fold 104 facilitate the connection between the base 4 and the annular peripheral wall 100. Furthermore, the connecting fold 104 extends inward from the bottom edge of the annular peripheral wall 100, ensuring that the connection structure between the base 4 and the annular peripheral wall 100 is located on the inner circumference of the annular peripheral wall 100, thus avoiding the problem of the connection structure protruding outwards and affecting the overall aesthetics.

[0093] Specifically, the top opening edge of the seat body 41 extends outward to form a flange 42 around the entire circumference or part of the edge. The flange 42 is horizontally arranged. The bottom inner circumference of the annular peripheral wall 100 is provided with a connecting fold 104. The connecting fold 104 is horizontally arranged. The flange 101 fits against the bottom of the connecting fold 104 and is then fixed by screws.

[0094] In some embodiments, the bottom edge of the annular peripheral wall 100 is bent upward and extended a certain distance before extending towards the center of the annular peripheral wall 100 to form a connecting folded edge 104.

[0095] In the above embodiment, the bottom edge of the annular peripheral wall 100 is first bent upward and extended a certain distance before extending inward to form a connecting flange 104. The entire connecting flange 104 is recessed inward to avoid the screws being exposed and affecting the overall aesthetics. The screws are not visible from the outside of the product, which can better hide the screws and connecting structures such as the flange 42, making it more aesthetically pleasing.

[0096] Specifically, the connecting flange 104 is an L-shaped annular flange, and the screw and the flanged part 42 are concealed within the accommodating space of the L-shaped annular flange.

[0097] In some embodiments, the flange 42 and the connecting fold 104 are provided with multiple sets of connecting holes at circumferential intervals, and the connectors are multiple, with the multiple connectors being connected one-to-one between the multiple sets of connecting holes.

[0098] In the above embodiments, by using multiple sets of connecting holes spaced apart along the circumference and connecting the multiple sets of connecting holes one-to-one with multiple connectors, the stability and reliability of the connection between the base 4 and the front shell 1 and the rear plate 2 can be further improved.

[0099] According to an embodiment of the present invention, in another aspect, a household appliance is provided, including the housing assembly of any of the above embodiments.

[0100] In some embodiments, the household appliance includes an electric heater. Preferably, the household appliance is a baseboard heater.

[0101] Of course, the household appliances in this embodiment are not limited to electric heaters, but can also be air-emitting household appliances such as humidifiers and air purifiers.

[0102] In this embodiment, the outer casing assembly of the entire unit consists of a front shell 1, a rear panel 2, an air vent grille 3, and a base 4, forming an overall elongated structure. The front shell 1 is a U-shaped integrated sheet metal part. The rear panel 2 is connected to the front shell 1 via plug-in and hook-and-loop connections. Both the front shell 1 and the rear panel 2 have flanges 101 on their inner top sides, with locking holes 102 on the flanges 101. The air vent grille 3 is fastened to the annular circumferential wall 100 formed by the assembly of the front shell 1 and the rear panel 2, and is fixed by buckles 31 and limited by limiting ribs 32. Finally, the base 4 is installed, and screws are driven into the bottom. The connection between the bottom and the front shell 1 and the rear panel 2 is designed as a recessed platform, and the screws are hidden by the wrapping effect of the front and rear panels 2. This achieves a screwless design on the five main exterior surfaces (front, rear, left, right, and top), leaving the screws on the bottom surface of the secondary exterior surfaces, greatly improving assembly efficiency and ensuring the consistency and aesthetics of the appearance.

[0103] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the protection scope of the embodiments of this application.
