[0043] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" are generally used in relation to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0044] To address the issue that the installation method of the control panel in the prior art affects its assembly stability, this application provides a housing assembly and an electric heater having the same.

[0045] like Figures 1 to 12As shown, the housing assembly includes a first housing 10, a second housing 20, and a panel 30. The first housing 10 includes a first snap-fit ​​portion 11 and a first positioning portion 12 spaced apart. The second housing 20 is disposed opposite to the first housing 10 and includes a second snap-fit ​​portion 21. The panel 30 is disposed on top of the first housing 10 and the second housing 20. The panel 30 includes a second positioning portion 31, a third snap-fit ​​portion 32, and a fourth snap-fit ​​portion 33 spaced apart, with the third snap-fit ​​portion 32 and the fourth snap-fit ​​portion 33 located on opposite sides of the second positioning portion 31. After the first positioning portion 12 and the second positioning portion 31 are engaged, the panel 30 is mounted on the first housing 10 and the second housing 20 by engaging the third snap-fit ​​portion 32 with the first snap-fit ​​portion 11 and the fourth snap-fit ​​portion 33 with the second snap-fit ​​portion 21.

[0046] Using the technical solution of this embodiment, after the first positioning part 12 and the second positioning part 31 are limited and engaged, the panel 30 is installed on the first housing 10 and the second housing 20 by engaging the third locking part 32 with the first locking part 11 and the fourth locking part 33 with the second locking part 21.

[0047] Compared with the single orientation of the panel in the prior art, the third snap-fit ​​portion 32 and the fourth snap-fit ​​portion 33 of the panel 30 in this embodiment are located on both sides of the second positioning portion 31, so that the first housing 10 and the second housing 20 are in multi-directional cooperation with the panel 30, thereby improving the assembly stability between the panel 30 and the first housing 10 and the second housing 20, and solving the problem that the installation method of the control panel affects its assembly stability in the prior art.

[0048] like Figure 12 As shown, the housing assembly also includes fasteners 40. The fasteners 40 are inserted into the first housing 10 and the second housing 20 to connect them. Thus, by rationally arranging the fasteners 40, not only is the structural stability of the housing assembly enhanced, but the number and position of the fasteners 40 can also be adjusted according to actual needs, making it suitable for housing assemblies of different sizes and shapes, and improving design flexibility.

[0049] Optionally, fastener 40 is a screw or bolt.

[0050] Optionally, there may be one fastener 40; or, there may be multiple fasteners 40, spaced apart along the height and / or width direction of the first housing 10; or, multiple fasteners 40 may be spaced apart along the height and / or circumferential direction of the first housing 10. This arrangement allows for greater flexibility in selecting the number and arranging the fasteners 40, meeting different usage requirements and working conditions, and also improving the processing flexibility for workers.

[0051] In this embodiment, there are multiple fasteners 40, which are spaced apart along the height direction and / or circumferential direction of the first housing 10, thereby improving the assembly stability of the first housing 10 and the second housing 20.

[0052] like Figure 2 As shown, one of the first positioning part 12 and the second positioning part 31 is a protruding post, and the other is a recessed part. The protruding post extends into the recessed part and engages with it to achieve positioning between the panel 30 and the first housing 10. This positioning method is simple and reliable, ensuring the accurate position of the panel 30 on the first housing 10 and the second housing 20, preventing the panel 30 from shaking during use, and improving the user experience. At the same time, this design allows for more flexible structural selection of the first positioning part 12 and the second positioning part 31 to meet different usage needs and working conditions, and also improves the processing flexibility of the operators.

[0053] In this embodiment, the first positioning part 12 is a protruding post and the second positioning part 31 is a recessed part. The protruding post extends into the recessed part and is limited and matched with the recessed part to realize the positioning between the panel 30 and the first housing 10.

[0054] In this embodiment, the recess is a through hole.

[0055] Optionally, the panel 30 has a display panel mounting area 36, ​​and there is one second positioning part 31, which is arranged to avoid the display panel mounting area 36; or, there are multiple second positioning parts 31, which are spaced apart around the display panel mounting area 36. This design ensures that the installation space of the display panel 50 is not affected. At the same time, the reasonable arrangement of the second positioning parts 31 improves the overall strength of the panel 30, extends the service life of the display panel 50, and makes the display of information such as the temperature setting and operating mode of the electric heater clearer and more convenient for users. Furthermore, the above arrangement allows for greater flexibility in selecting the number of second positioning parts 31 to meet different usage needs and working conditions, and also improves the processing flexibility of the operators.

[0056] In this embodiment, the housing assembly has a first disassembly / removal state and a second disassembly / removal state. The housing assembly is in the first disassembly / removal state by pushing the panel 30 towards the first housing 10 in a preset direction until the first positioning part 12 and the second positioning part 31 are engaged, and the first locking part 11 and the third locking part 32 are engaged. While the housing assembly is in the first disassembly / removal state, the housing assembly is switched from the first disassembly / removal state to the second disassembly / removal state by inserting fasteners 40 into the first housing 10 and the second housing 20, and by engaging the second locking part 21 with the fourth locking part 33. This design of the disassembly / removal states makes the installation and removal of the panel 30 more convenient, and the secondary fixation by the fasteners 40 further enhances the connection stability between the panel 30 and the first housing 10 and the second housing 20.

[0057] Specifically, the panel 30 is first horizontally inserted into the first housing 10 to achieve pre-fixation, and then the assembly and pressing between the first housing 10 and the second housing 20 achieves a reliable and stable technical effect.

[0058] like Figure 2 As shown, the first snap-fit ​​portion 11 includes a first plate 111 and a plurality of first reinforcing ribs 112. The first plate 111 is disposed on the inner wall of the first housing 10. The plurality of first reinforcing ribs 112 are disposed around the first plate 111, and each first reinforcing rib 112 is connected to the surface of the first plate 111 and the inner wall of the first housing 10. Thus, the above-mentioned arrangement of the first reinforcing ribs 112 improves the structural strength of the first snap-fit ​​portion 11, ensuring the secure installation of the panel 30 on the first housing 10. At the same time, the above arrangement simplifies the structure of the first snap-fit ​​portion 11, making it easier to process and implement, and reducing the processing cost and difficulty of the first snap-fit ​​portion 11.

[0059] like Figure 11 As shown, the third snap-fit ​​portion 32 includes a second plate 321 and a plurality of second reinforcing ribs 322. The second plate 321 is disposed on the inner surface of the panel 30 and has a first through hole for the first snap-fit ​​portion 11 to extend into. The plurality of second reinforcing ribs 322 are spaced apart along the extending direction of the second plate 321, and each second reinforcing rib 322 is connected to both the second plate 321 and the inner surface of the panel 30. This arrangement of the second reinforcing ribs 322 enhances the structural strength of the third snap-fit ​​portion 32, ensuring a stable connection between the panel 30 and the first housing 10, and extending the service life of the housing assembly. Simultaneously, this arrangement simplifies the structure of the third snap-fit ​​portion 32, making it easier to manufacture and implement, thus reducing the manufacturing cost and difficulty of the third snap-fit ​​portion 32.

[0060] like Figure 4As shown, the second snap-fit ​​portion 21 includes an annular structure 211 and a plurality of third reinforcing ribs 212. The annular structure 211 is disposed on the inner surface of the second housing 20. The plurality of third reinforcing ribs 212 are circumferentially spaced around the annular structure 211, and each third reinforcing rib 212 is connected to both the annular structure 211 and the inner surface of the second housing 20. Thus, the combination of the annular structure 211 and the third reinforcing ribs 212 not only improves the structural strength of the second snap-fit ​​portion 21, but also evenly distributes the pressure of the panel 30 on the second housing 20, maintaining a tight connection between the panel 30 and the second housing 20. Simultaneously, the above arrangement simplifies the structure of the second snap-fit ​​portion 21, making it easier to manufacture and implement, thus reducing the manufacturing cost and difficulty of the second snap-fit ​​portion 21.

[0061] like Figure 11 As shown, the fourth snap-fit ​​portion 33 includes a third plate 331 and a plurality of fourth reinforcing ribs 332. The third plate 331 is disposed on the inner surface of the panel 30 and has a second through hole for the second snap-fit ​​portion 21 to extend into. The plurality of fourth reinforcing ribs 332 are spaced apart along the extending direction of the third plate 331, and each fourth reinforcing rib 332 is connected to both the third plate 331 and the inner surface of the panel 30. This arrangement of the fourth reinforcing ribs 332 further enhances the structural strength of the fourth snap-fit ​​portion 33, ensuring a stable connection between the panel 30 and the second housing 20. Simultaneously, this arrangement simplifies the structure of the fourth snap-fit ​​portion 33, making it easier to manufacture and implement, thus reducing the manufacturing cost and difficulty of the fourth snap-fit ​​portion 33.

[0062] like Figure 9 As shown, a fifth latching portion 13 is provided on the first housing 10, and a sixth latching portion 34 is provided on the panel 30. Along the circumference of the panel 30, the sixth latching portion 34 is located between the second positioning portion 31 and the third latching portion 32. When the housing assembly is in the first disassembly / assembly state, the fifth latching portion 13 and the sixth latching portion 34 are engaged with each other. This arrangement further enhances the connection stability between the panel 30 and the first housing 10, ensuring the sealing and safety of the equipment's interior and preventing internal heat leakage.

[0063] like Figure 2As shown, the fifth snap-fit ​​portion 13 includes a first extension plate 131, a plurality of fifth reinforcing ribs 132, and a first hook-shaped portion 133. The first extension plate 131 is disposed on the inner surface of the first housing 10, and the plurality of fifth reinforcing ribs 132 are spaced apart along the width direction of the first extension plate 131. The first hook-shaped portion 133 is disposed on at least one surface of the first extension plate 131 for engaging with the sixth snap-fit ​​portion 34. The extension direction of the first extension plate 131 is consistent with the extension direction of the protrusion. Thus, the aforementioned arrangement of the first hook-shaped portion 133 makes the assembly and disassembly of the panel 30 more convenient, while the aforementioned arrangement of the fifth reinforcing ribs 132 improves the structural strength of the fifth snap-fit ​​portion 13. Furthermore, the aforementioned arrangement simplifies the structure of the fifth snap-fit ​​portion 13, making it easier to manufacture and implement, thus reducing the manufacturing cost and difficulty of the fifth snap-fit ​​portion 13.

[0064] like Figure 11 As shown, the sixth snap-fit ​​portion 34 includes two fourth plates 341 and a fifth plate 342 disposed opposite to each other. The two fourth plates 341 are connected by the fifth plate 342, which is used to snap-fit ​​with the first hook-shaped portion 133. Thus, the sixth snap-fit ​​portion 34 is formed by two fourth plates 341 and one fifth plate 342, which not only enhances the structural strength of the sixth snap-fit ​​portion 34 but also ensures a stable fit with the fifth snap-fit ​​portion 13, extending the service life of the panel 30. At the same time, the above arrangement simplifies the structure of the sixth snap-fit ​​portion 34, making it easier to manufacture and implement, reducing the manufacturing cost and difficulty of the sixth snap-fit ​​portion 34.

[0065] like Figure 4 As shown, a support portion 22 is provided on the inner surface of the second housing 20. The support portion 22 is located below the second snap-fit ​​portion 21. The support portion 22 includes a sixth plate 221 and a plurality of sixth reinforcing ribs 222. The plate surface of the sixth plate 221 faces the panel 30 to support the panel 30. The plurality of sixth reinforcing ribs 222 are spaced apart along the extending direction of the sixth plate 221. In this way, the above-mentioned configuration of the support portion 22 provides additional support for the panel 30, improving the installation stability of the panel 30. At the same time, the support portion 22 can ensure a safe distance between the heating element and the panel 30, avoiding deformation or damage to the panel 30 due to overheating, and also improving the thermal efficiency and safety of the electric heater.

[0066] Optionally, there may be one support portion 22; or there may be multiple support portions 22, which are spaced apart along the width or circumferential direction of the second housing 20. This arrangement allows for greater flexibility in selecting the number of support portions 22 to meet different usage requirements and working conditions, and also improves the processing flexibility of the workers. Furthermore, multiple support portions 22 enhance their load-bearing capacity, ensuring they can support panels 30 of varying weights.

[0067] like Figure 10 and Figure 11 As shown, the panel 30 also includes a seventh latching portion 35, which includes a second extension plate 351 and a second hook-shaped portion 352. The second hook-shaped portion 352 is disposed on at least one surface of the second extension plate 351, forming a limiting space between the second hook-shaped portion 352 and the inner surface of the panel 30. The display panel 50 extends into the limiting space to limit and stop its movement. This configuration provides precise positioning and secure fixation for the display panel 50, preventing displacement and shaking during use and improving the stability and clarity of the display effect.

[0068] In this embodiment, the display panel 50 is mainly used to provide feedback information to the user and display the current working status of the device; the user interacts with the device through the panel 30. Specifically, the display panel 50 is installed on the inner surface of the panel 30, and the display panel 50 is fixed by pressing it to be fastened by the seventh latching part 35 on the panel 30.

[0069] In this embodiment, the assembly process of the housing is as follows:

[0070] First, align the through hole of panel 30 with the protrusion of first housing 10, and insert panel 30 horizontally into first housing 10. At this time, the first locking part 11 on first housing 10 is inserted into the first locking part 11 on panel 30, further reinforcing and restricting the degree of freedom of panel 30 in the X and Z axes. When panel 30 is pushed all the way in horizontally, the fifth locking part 13 on first housing 10 will engage with the sixth locking part 34 on panel 30, restricting the degree of freedom of panel 30 in the Y axis. At this point, first housing 10 and panel 30 are installed and panel is fixed. Then, insert the second locking part 21 on second housing 20 into the fourth locking part 33 on panel 30. At the same time, the supporting part on second housing 20 just supports panel 30, further stabilizing panel 30 and enhancing reliability.

[0071] like Figure 12 As shown, this application also provides an electric heater, including the aforementioned housing assembly.

[0072] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0073] The housing assembly includes a first housing, a second housing, and a panel. The first housing includes a first snap-fit ​​portion and a first positioning portion spaced apart. The second housing is disposed opposite to the first housing and includes a second snap-fit ​​portion. The panel is disposed on top of the first and second housings and includes a second positioning portion, a third snap-fit ​​portion, and a fourth snap-fit ​​portion spaced apart. The third and fourth snap-fit ​​portions are respectively located on both sides of the second positioning portion. Thus, after the first and second positioning portions are engaged, the panel is mounted on the first and second housings by engaging the third snap-fit ​​portion with the first snap-fit ​​portion and the fourth snap-fit ​​portion with the second snap-fit ​​portion.

[0074] Compared with the single constraint orientation of the panel in the prior art, the third and fourth snap-fit ​​parts of the panel in this application are located on both sides of the second positioning part, so that the first housing and the second housing are in multi-directional cooperation with the panel, thereby improving the assembly stability between the panel and the first housing and the second housing, and solving the problem that the installation method of the control panel affects its assembly stability in the prior art.
