Description

Technical Field

[0001] This utility model belongs to the field of air conditioning technology, specifically relating to an electrical box housing assembly and an air conditioner. Background Technology

[0002] Residential air conditioners are a common type of ducted air conditioner in the US market, typically installed in indoor stairwells, attic ceilings, etc. They are small in size and have a compact internal structure. To enhance heating performance in winter, these air conditioners can be equipped with an electric heater, which is not included at the factory but installed after the customer's request. The electric heater is generally installed at the air outlet. Although installation positions are provided, most existing products require disassembling the electrical box of the unit before installing the heater, and then reinstalling the electrical box. This disassembly and reassembly of the electrical box is cumbersome. To solve this problem, existing patents disclose a solution that uses the side of the electrical box as a rotation axis, allowing the electrical box to rotate. This method eliminates the need to disassemble the electrical box; when the heater needs to be installed, simply rotate the electrical box to remove it from its obstructed position. However, in existing electrical boxes, the rotation process pulls on the wiring, reducing wiring reliability. Therefore, this problem needs to be addressed. Utility Model Content

[0003] Therefore, this utility model provides an electrical box housing assembly and an air conditioner, which can solve the technical problem in the prior art that the electrical box pulls on the wiring during rotation, resulting in a decrease in the reliability of the wiring.

[0004] To address the aforementioned problems, this utility model provides an electrical box housing assembly, comprising a mounting component and an electrical box housing. The mounting component has a first through-hole extending through both sides, and the electrical box housing has a second through-hole extending into the interior. The electrical box housing is rotatably engaged with the mounting component, and the second through-hole communicates with the first through-hole. Furthermore, the electrical box housing can rotate around the center line of the first through-hole.

[0005] In some embodiments, the mounting component is provided with a connecting post, the first wire passage hole passes through the opposite ends of the connecting post, and the electrical box housing is sleeved on the connecting post through the second wire passage hole, so that the first wire passage hole is located inside the second wire passage hole, and the second wire passage hole communicates with the first wire passage hole.

[0006] In some embodiments, the electrical box housing has an outer housing layer and an inner housing layer, and the second wire hole has a first hole segment located on the outer housing layer;

[0007] The connecting post has a circumferentially extending guide groove on the side wall between its two ends. The outer shell of the electrical box is inserted into the guide groove through the opening edge of the first hole section. The opening edge of the first hole section slides with the guide groove so that when sliding along the guide groove, it drives the outer shell of the electrical box to rotate around the center line of the first wire hole.

[0008] In some embodiments, the opening edge of the first hole segment has a protrusion protruding inwards from the first hole segment; the opening edge of the first hole segment is engaged in the guide groove through the protrusion, and slides with the guide groove through the protrusion.

[0009] In some embodiments, the two ends of the connecting post through which the first wire hole passes are respectively a first end and a second end, the first end and the second end being two ends in the centerline direction of the connecting post; wherein, the connecting post is connected to the mounting member through the second end, and the first end protrudes from the mounting member, and the first end has a groove extending through the guide groove, the groove extending along the centerline direction of the connecting post;

[0010] The protrusion is used to insert into the groove along the center line of the connecting post, and then into the guide groove along the circumferential direction of the connecting post.

[0011] In some embodiments, the first end is located in the space between the outer shell layer and the inner shell layer.

[0012] In some embodiments, the connecting post is detachable from the mounting component.

[0013] In some embodiments, the mounting member has opposing first and second sides, and the mounting member also has a mounting hole extending from the first side to the second side, the connecting post is located on the first side, and the connecting post has threaded holes extending through opposite ends;

[0014] The electrical box housing assembly further includes a connecting pipe and a locking part disposed on the outer side wall of the connecting pipe. The connecting pipe has an external thread and is used to pass through the mounting hole from the second side and be screwed into the threaded hole. The locking part abuts against the second side. The pipe hole of the connecting pipe constitutes the first wire passage hole.

[0015] In some embodiments, one of the connecting post and the first side is provided with a positioning protrusion, and the other is provided with a positioning groove for interlocking with the positioning protrusion.

[0016] This utility model also provides an air conditioner, which includes the electrical box housing assembly assembly described in any one of the above descriptions.

[0017] In some embodiments, the air conditioner further includes an electric heater mounting location;

[0018] The outer casing of the electrical box can rotate around the center line of the first wire hole to a first position and a second position. When rotated to the first position, it blocks the installation of the electric heater into the electric heater mounting position, and when rotated to the second position, it opens up the electric heater mounting position so that the electric heater can be installed into the electric heater mounting position.

[0019] In some embodiments, the air conditioner further includes fasteners;

[0020] When the outer casing of the electrical box is in the first position, it is secured by the fastener, wherein the fastener is removable.

[0021] The electrical box housing assembly and air conditioner provided by this utility model have the following beneficial effects:

[0022] 1. The wiring inside the electrical box is routed through the first wire hole. Since the outer shell of the electrical box rotates around the center line of the first wire hole, it will not pull on the wiring inside the first wire hole, thereby improving the reliability of the wiring inside the electrical box.

[0023] 2. The outer shell of the electrical box is rotatably snapped onto the mounting piece, and only a single fastener is needed to reliably fix the outer shell of the electrical box.

[0024] 3. When installing an electric heater on the air conditioner after the service, the electrical box will not be obstructed, making installation convenient. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0041] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0042] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0043] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0044] See also Figure 1-2As shown, according to an embodiment of the present invention, an electrical box housing assembly is provided, which includes a mounting member 2 and an electrical box housing 1. The mounting member 2 is provided with a first wire-passing hole 102 extending through both sides. The electrical box housing 1 has a second wire-passing hole 101 extending to the interior. The electrical box housing 1 is rotatably snapped onto the mounting member 2, and the second wire-passing hole 101 communicates with the first wire-passing hole 102, and the electrical box housing 1 can rotate about the center line of the first wire-passing hole 102.

[0045] In the above example, the wiring inside the electrical box runs through the first wire hole 102. Since the outer shell 1 of the electrical box rotates around the center line of the first wire hole 102, it will not pull on the wiring inside the first wire hole 102, thereby improving the reliability of the wiring inside the electrical box.

[0046] In some embodiments, the center lines of the aforementioned first wire hole 102 and second wire hole 101 coincide, which is beneficial for wire routing.

[0047] In some implementations, such as Figure 1 and Figure 2 As shown, the aforementioned mounting component 2 can be plate-shaped. The aforementioned electrical box housing 1 can be rotatably connected to the mounting component 2 via bearings, hinges, etc., to enable the electrical box housing 1 to rotate.

[0048] To achieve the effect of connecting the first wire hole 102 and the second wire hole 101, in some embodiments, such as... Figure 1-2 As shown, the aforementioned mounting component 2 is provided with a connecting post 3, and the aforementioned first wire passage hole 102 passes through the opposite ends of the connecting post 3. The electrical box housing 1 is sleeved on the connecting post 3 through the second wire passage hole 101, so that the first wire passage hole 102 is located inside the second wire passage hole 101, and the second wire passage hole 101 communicates with the first wire passage hole 102.

[0049] In the above example, by placing the first cable hole 102 inside the second cable hole 101, the second cable hole 101 is connected to the first cable hole 102, and the overall wiring structure is made more compact.

[0050] To achieve the effect of the aforementioned electrical box housing 1 being rotatably snapped onto the mounting component 2, in some embodiments, such as Figure 2-4 As shown, the aforementioned electrical box housing 1 has an outer housing layer 11 and an inner housing layer 12. The aforementioned second wire-passing hole 101 has a first hole segment 101b located on the outer housing layer 11. Figure 5As shown, the aforementioned connecting post 3 has a circumferentially extending guide groove 312 on the side wall between its two ends. The electrical box housing 1 is inserted into the guide groove 312 through the opening edge of the first hole section 101b. The opening edge of the first hole section 101b is slidably engaged with the guide groove 312 so that when sliding along the guide groove 312, it drives the electrical box housing to rotate around the center line of the first wire hole 102.

[0051] In the above example, the opening edge of the first hole segment 101b is equivalent to a shaft hole, and the guide groove 312 segment of the connecting column 3 is equivalent to a rotating shaft. Thus, when the opening edge of the first hole segment 101b slides along the guide groove 312, it is equivalent to the shaft hole rotating relative to the rotating shaft. The two opposing groove walls of the guide groove 312 can stop and limit the opening edge of the first hole segment 101b, effectively engaging the opening edge of the first hole segment 101b within the guide groove 312.

[0052] In some embodiments, a heat-insulating material, such as a sponge, may be provided between the aforementioned outer shell layer 11 and inner shell layer 12, which can achieve the effect of heat preservation and condensation prevention.

[0053] In some implementations, such as Figure 3 As shown, the opening edge of the aforementioned first hole segment 101b has a protrusion 103 protruding inward from the first hole segment 101b. The opening edge of the first hole segment 101b is engaged in the guide groove 312 through the protrusion 103, and the protrusion 103 slides in cooperation with the guide groove 312.

[0054] In the example above, the opening edge of the first hole segment 101b is slidably engaged with the guide groove 312 only through the protrusion 103, which can reduce frictional resistance.

[0055] In some implementations, such as Figure 3 As shown, the aforementioned second through hole 101 has a second hole segment 101a located on the outer shell layer 11. This second hole segment 101a is designed without sharp corners in the circumferential direction, thus preventing it from cutting the inner traces. In a specific application example, the second hole segment 101a can be a circular hole.

[0056] In some embodiments, the portion of the opening edge of the aforementioned first hole segment 101b that extends beyond the protrusion 103 forms a first edge segment. The projection of the aforementioned second hole segment 101a onto the centerline direction of the first hole segment 101b is located inside the first edge segment.

[0057] In the above example, the first hole segment 101b is designed to be larger than the second hole segment 101a, mainly to facilitate the insertion of the opening edge of the first hole segment 101b into the aforementioned guide groove 312.

[0058] In order to engage the protrusion 103 into the guide groove 312, in some embodiments, such as Figure 5-6 As shown, the two ends of the connecting post 3 through the first wire hole 102 are a first end 31 and a second end 32, respectively. The first end 31 and the second end 32 are the two ends along the centerline direction m of the connecting post. The connecting post 3 is connected to the mounting member 2 through the second end 32. The first end 31 protrudes from the mounting member 2 and has a groove 311 extending into the guide groove 312. The groove 311 extends along the centerline direction m of the connecting post. The protrusion 103 is used to insert into the groove 311 along the centerline direction m of the connecting post, and then into the guide groove 312 along the circumferential direction n of the connecting post.

[0059] In the above example, the design of the groove 311 facilitates the smooth insertion of the protrusion 103 into the guide groove 312.

[0060] In some embodiments, there may be two protrusions 103, located on opposite sides of the opening edge of the first hole segment 101b. The number of grooves 311 is equal to the number of protrusions 103, and they correspond one-to-one.

[0061] In some embodiments, the aforementioned first end 31 is located in the space between the outer shell layer 11 and the inner shell layer 12, which can prevent the connecting post 3 from extending into the interior of the electrical box housing 1, making the overall installation structure more compact.

[0062] In a specific application example, such as Figure 5 As shown, the aforementioned guide groove 312 divides the connecting post 3 into a first segment 301 and a second segment 302. The first segment 301 has the aforementioned first end 31, and the second segment 302 has the aforementioned second end 32. The first segment 301 may be cylindrical, and the second segment 302 may have a regular hexagonal shape, which facilitates tightening with a wrench during assembly.

[0063] In some embodiments, the aforementioned connecting post 3 can be detached from the mounting member 2, thus facilitating the maintenance and replacement of the connecting post 3. Of course, in other embodiments, the connecting post 3 can also be integrally formed on the mounting member 2, so as to be integrally formed with the mounting member 2.

[0064] To achieve the effect of making the connecting post 3 detachable, in some embodiments, such as Figure 7-10As shown, the aforementioned mounting member 2 has a first side 21 and a second side 22 facing each other. The mounting member 2 also has a mounting hole 202 extending from the first side 21 to the second side 22. The aforementioned connecting post 3 is located on the first side 21 of the mounting member 2, and the connecting post 3 has threaded holes 300 extending through both opposite ends. The electrical box housing assembly of this utility model also includes a connecting tube 5 and a locking portion 501 disposed on the outer wall of the connecting tube 5, the locking portion 501 being integrally formed on the connecting tube 5. The connecting tube 5 has external threads. The connecting tube 5 is used to pass through the mounting hole 202 from the second side 22 and be screwed into the threaded hole 300, and the locking portion 501 abuts against the second side 22. The tube hole 502 of the connecting tube 5 constitutes the aforementioned first wire passage hole 102.

[0065] In the above example, the connecting tube 5 can be screwed into the threaded hole 300 of the connecting post 3 by screwing it in until the locking part 501 abuts against the second side 22, at which point the connecting post 3 is fixed. When it is necessary to disassemble the connecting post 3, simply unscrew the connecting tube 5 from the connecting post 3.

[0066] It should be noted that the mounting hole 202 mentioned above can be a round hole. In some cases, the connecting post 3 mentioned above is also called a fixing nut.

[0067] In some implementations, such as Figure 8 As shown, a sealing ring 4 can also be fitted onto the aforementioned connecting pipe 5. The sealing ring 4 is located between the locking part 501 and the second side 22 of the mounting member 2, so that the locking part 501 abuts against the second side 22 through the sealing ring 4. The sealing ring 4 can improve the sealing performance at the mounting hole 202.

[0068] In some implementations, such as Figure 10 As shown, the aforementioned locking part 501 is located in the middle of the connecting pipe 5. The locking part 501 divides the connecting pipe 5 into a first pipe section 51 and a second pipe section 52, both of which have external threads. The connecting pipe 5 passes through the second side 22 via the first pipe section 51, through the mounting hole 202, and is threadedly connected to the threaded hole 300. The electrical box housing assembly of this utility model also includes a locking nut 6, which is used to screw onto the second pipe section 52. When the locking nut 6 is screwed onto the second pipe section 52 in the first direction, it can compress the second pipe section 52, reducing its inner diameter to decrease the gap between the second pipe section 52 and the internal wiring, thus improving the sealing performance. When the locking nut 6 is screwed onto the second pipe section 52 in the second direction, it can loosen the second pipe section 52, increasing its inner diameter.

[0069] It should be noted that the specific structure of the locking nut 6 and the second pipe section 52 that makes the inner diameter of the second pipe section 52 larger or smaller is existing technology and will not be described in detail here.

[0070] It should be noted that the aforementioned connecting post 3 and connecting pipe 5 cooperate to form a locking structure, which connects the electrical box housing 1 and the mounting part 2, allowing the electrical box housing 1 to rotate relative to the mounting part 2. The pipe hole 502 of the connecting pipe 5 serves as the aforementioned first wire-passing hole 102, assisting in wire routing. The connecting post 3 can be made of metal; in some cases, the connecting post 3 may also be referred to as a metal wire-passing coil.

[0071] In some implementations, such as Figure 6-7 As shown, one of the aforementioned mounting plate 21 and the connecting post 3 is provided with a positioning protrusion 201, and the other is provided with a positioning groove 313 for interlocking with the positioning protrusion 201. The positioning protrusion 201 and the positioning groove 313 cooperate to position the connecting post 3, ensuring that the installation angle of the connecting post 3 is fixed.

[0072] The number of the aforementioned positioning protrusions 201 can be two or more, and the number of positioning grooves 313 is equal to the number of positioning protrusions 201, and they correspond one-to-one. Among them, a larger number of positioning protrusions 201 and positioning grooves 313 can improve the positioning accuracy of the connecting post 3.

[0073] This utility model also provides an air conditioner, which may include the electrical box housing assembly of any of the above. Because the air conditioner uses the aforementioned electrical box housing assembly, the wiring inside the electrical box runs through the first wire-passing hole 102. Since the electrical box rotates around the center line of the first wire-passing hole 102, the wiring inside the first wire-passing hole 102 will not be pulled, thereby improving the reliability of the wiring inside the electrical box.

[0074] In some embodiments, the aforementioned air conditioner may further include an electric heater mounting position 10. The electrical box housing 1 is rotatable about the centerline of the first wiring hole 102 to a first position and a second position, such that when rotated to the first position, it prevents the electric heater 9 from being installed into the electric heater mounting position 10 (e.g., ...). Figure 11 (as shown), and when rotated to the second position, the electric heater mounting position 10 is cleared (as shown). Figure 12 As shown), this allows the electric heater 9 to be installed in the electric heater mounting position 10.

[0075] In the above example, when it is necessary to install the electric heater 9 into the air conditioner, by rotating the electrical box housing 1 to the second position, the electrical box housing 1 can be moved aside from the electric heater mounting position 10, so that the electric heater 9 can be installed into the electric heater mounting position 10. At this time, the electrical box will not block the view, and the installation is convenient.

[0076] like Figure 11As shown, the aforementioned air conditioner also includes a fastener 8. The electrical box housing 1 is secured by the fastener 8 in the aforementioned first position. The fastener 8 is removable. In a specific application example, the fastener 8 can be a screw, etc.

[0077] In the above example, the electrical box housing 1 can be fixed by the fastener 8 to prevent the electrical box housing 1 from rotating without cause, thereby improving the reliability of the electrical box housing 1.

[0078] In some embodiments, the aforementioned fasteners 8 can be a single unit, which allows for quick disassembly of the electrical box housing 1, reducing the number of fasteners 8 that need to be removed during disassembly, and eliminating the need for wire disconnection. Furthermore, the electrical box housing 1 does not detach from the main unit after disassembly; it can be stably fixed when rotated to one side, preventing it from falling or shaking, and does not affect the assembly of the electric heater 9.

[0079] like Figure 11 As shown, the aforementioned mounting component 2 may be provided with a baffle 7. When the electrical box housing 1 is rotated to the aforementioned first position, the baffle 7 abuts against the electrical box housing 1 to stop and limit the electrical box housing 1.

[0080] The assembly process of the electrical box housing 1 and the mounting part 2 is as follows: When assembling the electrical box housing 1, the protrusion 103 on the first hole section 101b of the electrical box housing 1 is aligned with the groove 311 on the connecting post 3. After the protrusion 103 is inserted into the groove 311, the electrical box housing 1 is rotated to the left. The electrical box housing 1 drives the protrusion 103 to slide in the guide groove 312. The electrical box housing 1 is rotated to the position of the baffle 7, and can be installed in place. A fastener 8, such as a screw, is installed at the outermost position of the electrical box housing 1. When the air conditioner needs to be equipped with an electric heater 9, the fastener 8 is removed, and the electrical box housing 1 is rotated to the right to make enough space to install the electric heater 9. Since the electrical box housing 1 rotates around the center line of the first wire hole 102, the electrical box housing 1 will not pull the wires when rotating, ensuring reliability. When the outer casing 1 of the electrical box rotates, the protrusion 103 at the bottom of the outer casing 1 of the electrical box always moves in the guide groove 312 of the connecting column 3. The outer casing 1 of the electrical box will not fall off when it is rotated to the rightmost cantilever position. The installer can operate the installation of the electric heater 9 with confidence.

[0081] It will be readily understood by those skilled in the art that, without conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.

[0082] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
