Screen structure and ducted fan assembly

Abstract

This disclosure relates to a filter structure and a duct unit assembly. The filter structure includes a filter housing, and a wiring passage structure is provided on the side of the filter housing near the electrical control box of the duct unit assembly. By providing the wiring passage structure on the side of the filter housing near the electrical control box, the filter structure allows the wiring harness within the filter structure to connect to the electrical control box from the outside of the filter structure, facilitating wiring operations. Furthermore, because the wiring passage structure is close to the electrical control box, the length of the wiring harness can be reduced to some extent, thereby reducing or even preventing the wiring harness from becoming tangled due to excessive length. Based on this, the assembly and disassembly efficiency of the duct unit assembly is improved.

Technical Field

[0001] This disclosure relates to the field of air conditioning technology, and more specifically, to a filter structure and a duct assembly. Background Technology

[0002] In related technologies, electronic components such as sensors inside the filter structure of the duct unit assembly are generally connected to the electrical control box of the duct unit assembly by routing wires from inside the filter structure. However, this method is inconvenient for wiring operations and affects the disassembly and assembly efficiency of the duct unit assembly. Utility Model Content

[0003] The purpose of this disclosure is to provide a filter structure and a duct assembly, wherein the wiring harness of the filter structure can be routed from the outside of the filter structure and connected to the electrical control box, thereby at least partially solving the above-mentioned technical problems.

[0004] To achieve the above objectives, a first aspect of this disclosure provides a filter structure for a duct unit assembly, the filter structure including a filter housing, and a wiring structure provided on the side of the filter housing near the electrical control box of the duct unit assembly.

[0005] Optionally, the filter housing includes an upper cover and a lower cover detachably connected to the upper cover; the wire passage structure includes a wire passage hole and a limiting part for restricting the movement of the wire harness, one of the wire passage hole and the limiting part being disposed on the upper cover and the other being disposed on the lower cover.

[0006] Optionally, the wire hole is disposed on the side wall of the upper cover, and the limiting part is disposed on the side wall of the lower cover.

[0007] Optionally, the wire hole and the limiting part are respectively provided after the upper cover and the lower cover are connected.

[0008] Optionally, the limiting part includes a limiting groove and a limiting opening for the wire harness to be inserted into the limiting groove.

[0009] Optionally, the projection of the limiting groove in a first direction after the upper cover and the lower cover are connected covers at least a portion of the wire hole; and / or, the limiting opening is provided with a guide surface on the side opposite to the limiting groove.

[0010] Optionally, the filter housing includes a mounting chamber for housing the sensor, and the wire-passing structure is disposed on the side away from the sensor.

[0014] Through the above technical solution, the filter structure disclosed herein has a wire-passing structure on the side of the filter housing near the electrical control box, which allows the wire harness inside the filter structure to be connected to the electrical control box from the outside of the filter structure, facilitating wiring operations for the staff. In addition, since the wire-passing structure is close to the electrical control box, the length of the wire harness can also be reduced to a certain extent, thereby reducing or even avoiding the situation where the wire harnesses are tangled together due to excessive length. Based on this, the disassembly and assembly efficiency of the duct unit assembly is improved.

Detailed Implementation

[0024] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0025] In this disclosure, unless otherwise stated, directional terms such as "inner" and "outer" refer to "inner" and "outer" relative to the contour of the corresponding component itself. Furthermore, in the following description, when referring to the accompanying drawings, unless otherwise explained, the same reference numerals in different drawings denote the same or similar elements. The above definitions are for explanation and illustration only and should not be construed as limiting this disclosure.

[0026] In related technologies, the filter housing of the filter structure in the duct air conditioner assembly generally has two mounting positions. One mounting position is used to install the filter, and the other mounting position is used to install the sensor. The sensor wiring harness can be routed from inside the filter structure to connect to the electrical control box of the duct air conditioner assembly. Although this ensures the overall aesthetics of the duct air conditioner assembly from the outside, the limited space inside the duct air conditioner assembly makes it inconvenient for operators to perform wiring operations, thus affecting the efficiency of duct air conditioner assembly and disassembly.

[0027] In order to at least partially solve the above-mentioned technical problems, the filter structure and duct assembly in the exemplary embodiments of this disclosure will be described below with reference to the accompanying drawings.

[0028] refer to Figures 1 to 5 As shown, in a first aspect, this disclosure provides a filter structure for a duct unit assembly. The filter structure includes a filter housing 1, and a wiring structure 2 is provided on the side of the filter housing 1 near the electrical control box 7 of the duct unit assembly. The wiring harness of the sensor 8 inside the filter housing 1 can be connected to the electrical control box 7 from the outside of the filter housing 1 through the wiring structure 2. Since the operating space outside the filter housing 1 is relatively large, it is convenient for operators to connect the wiring harness of the sensor 8 to the electrical control box 7. In addition, since the wiring structure 2 is located on the side of the filter housing 1 near the electrical control box 7, the distance between the wiring structure 2 and the electrical control box 7 can be minimized as much as possible, thereby reducing the length of the sensor 8 wiring harness to a certain extent, thereby reducing or even avoiding the situation where the wiring harness is tangled due to excessive length. Based on this, the disassembly and assembly efficiency of the duct unit assembly is improved.

[0029] In embodiments of this disclosure, such as Figures 1 to 3As shown, the filter housing 1 may include an upper cover 11 and a lower cover 12 detachably connected to the upper cover 11; the wire passage structure 2 includes a wire passage hole 21 and a limiting part 22 for restricting the movement of the wire harness, one of which is disposed on the upper cover 11 and the other on the lower cover 12. When connecting the wire harness to the electrical control box 7, the wire harness can first be connected to the limiting part 22 to restrict the movement of the wire harness. Thus, when the upper cover 11 and the lower cover 12 of the filter housing 1 are connected, the stability of the wire harness can be ensured, facilitating the assembly of the filter housing 1.

[0030] The upper cover 11 and the lower cover 12 can be connected in various ways. For example, both the upper cover 11 and the lower cover 12 can be provided with connecting holes. When they are connected, the connecting holes on the upper cover 11 can be correspondingly set with the connecting holes on the lower cover 12, so that the upper cover 11 and the lower cover 12 can be connected by fasteners such as bolts or screws. Alternatively, one of the upper cover 11 and the lower cover 12 can be provided with a snap-fit ​​structure, and the other can be provided with a snap-fit ​​mating part that can engage with the snap-fit ​​structure, that is, the upper cover 11 and the lower cover 12 can be snapped together. Or, the upper cover 11 and the lower cover 12 can be connected by a combination of fastener connection and snap-fit ​​connection. This disclosure does not make any specific limitation in this regard.

[0031] To facilitate the installation of internal components of the filter housing 1, such as Figures 1 to 3 As shown, the lower cover 12 of the filter housing 1, that is, the cover near the air duct body 5 after the filter housing 1 is connected to the air duct body 5 of the air duct assembly, can be provided with mounting positions for installing the filter 6 and the sensor 8. Therefore, the wire hole 21 can be provided on the side wall of the upper cover 11, and the limiting part 22 can be provided on the side wall of the lower cover 12. In this way, the sensor 8 and the limiting part 22 can be located on the same cover, which facilitates the connection of the wire harness to the limiting part 22.

[0032] Of course, in some configurations not shown, the limiting part 22 may also be provided on the upper cover 11, and the wire hole 21 may be provided on the lower cover 12.

[0033] In some implementations, such as Figures 1 to 3 As shown, the wire hole 21 and the limiting part 22 are correspondingly provided after the upper cover 11 and the lower cover 12 are connected. That is, when the wire harness is connected to the limiting part 22, the upper cover 11 and the lower cover 12 are connected so that the wire harness can pass through the wire hole 21, thereby facilitating the wire harness to pass out of the filter housing 1 and connect to the electrical control box 7.

[0034] In some embodiments not shown, the wire hole 21 and the limiting part 22 can also be set at any position on the upper cover 11 and the lower cover 12, that is, some areas of the two can correspond to each other or be set separately, as long as the limiting part 22 can restrict the movement of the wire harness and facilitate the connection between the upper cover 11 and the lower cover 12.

[0035] Specifically, such as Figures 1 to 4 As shown, the limiting part 22 may include a limiting groove 221 and a limiting opening 222 for inserting the wire harness into the limiting groove 221. For example, when the limiting part 22 is located on the lower cover 12 and the wire hole 21 is located on the upper cover 11, when the wire harness is connected to the control box 7, the operator can first place the wire harness against the side of the limiting opening 222 outside the limiting groove 221, and then press the wire harness firmly towards the limiting groove 221. This will allow the wire harness to be inserted into the limiting groove 221 through the limiting opening 222, thereby limiting the movement of the wire harness within a certain range, facilitating subsequent wire harness connection and the installation of the upper cover 11 and the lower cover 12.

[0036] In addition, the limiting groove 221 can be extended in the height direction of the filter housing 1, so that the length of the left and right sides of the limiting groove 221 can be longer. The limiting opening 222 can be set on the left or right side of the limiting groove 221, thereby making it easier for the staff to insert the wire harness into the limiting groove 221 through the limiting opening 222.

[0037] In embodiments of this disclosure, such as Figure 3 and Figure 4 As shown, after the upper cover 11 and the lower cover 12 are connected, the projection of the limiting groove 221 on the first direction A covers at least part of the wire hole 21. This makes it easier for the wire harness located in the limiting groove 221 to pass directly through the wire hole 21 after the upper cover 11 is connected to the lower cover 12, thereby improving wiring efficiency.

[0038] For example, the limiting groove 221 on the lower cover 12 may include a first limiting area 2211 and a second limiting area 2212 adjacent to the first limiting area 2211 in the height direction. The first limiting area 2211 may be correspondingly set with the wire hole 21 on the upper cover 11 in the first direction A, and the limiting opening 222 may be set on the second limiting area 2212. That is, the second limiting area 2212 is correspondingly set with the side wall of the upper cover 11 in the first direction A. In this way, after the wire harness is inserted into the limiting groove 221 and the upper cover 11 and the lower cover 12 are assembled, the wire hole 21 can further limit the movable area of ​​the wire harness while allowing the wire harness to pass through the filter housing 1, so as to ensure the stability of the wire harness after it is connected to the electrical control box 7.

[0039] In addition, the groove opening of the limiting groove 221 can be oriented toward the extension direction of the filter screen housing 1, that is, the side wall of the upper cover 11 or the lower cover 12 can form the groove wall of the limiting groove 221, so as to simplify the process of setting the limiting groove 221 and the space it occupies to a certain extent.

[0040] Of course, in some embodiments not shown, the opening of the limiting groove 221 can face any direction.

[0041] In addition, a guide surface 3 is provided on the side of the limiting opening 222 that is away from the limiting groove 221. For example, when the wire hole 21 is provided on the upper cover 11 and the limiting groove 221 is provided on the lower cover 12, the area adjacent to the limiting groove 221 and the limiting opening 222 can be provided with an inclined surface extending toward the limiting opening 222. This inclined surface forms a guide surface 3, so that when the wire harness passes through the limiting opening 222, it can move accurately along the guide surface 3 to the position of the limiting opening 222 and then be inserted into the limiting groove 221. In addition, if the groove opening of the limiting groove 221 is oriented toward the extension direction of the filter housing 1, that is, the side wall of the lower cover 12 can form the groove wall of the limiting groove 221, then an inclined surface extending toward the limiting opening 222 can also be formed on the side of the groove wall facing the upper cover 11 to form a guide surface 3, so as to facilitate the wire harness being inserted into the limiting groove 221. Thus, the guide surface 3 provided on the limiting groove 221 and the filter housing 1 can form a V-shaped structure, which improves the insertion efficiency of the wire harness into the limiting groove 221.

[0042] In some implementations, such as Figure 3 As shown, the filter housing 1 may include a mounting chamber 4 for housing the sensor 8, and the wiring structure 2 is disposed on the side away from the sensor 8. The sensor 8 may be an air quality sensor capable of detecting air quality, such as, for example, a PM2.5 sensor, a carbon dioxide sensor, and a formaldehyde sensor. One or more sensors 8 may be disposed in the mounting chamber 4 as needed, and their types may be appropriately matched as required. Of course, in order to allow air outside the filter housing 1 to pass through the sensor 8, the upper cover 11 and the lower cover 12 may be provided with through holes identical to those in the mounting chamber 4. These through holes allow air circulation so that the sensor 8 can detect the air quality. In addition, in order to facilitate the arrangement and connection of the wiring harness, the wiring structure 2 and the sensor 8 may be located on opposite sides, so that the wiring harness can be connected to the electrical control box 7 more smoothly through the wiring structure 2 while avoiding the occurrence of wiring harness tangling.

[0043] The second aspect of this disclosure, such as Figure 5 As shown, a ducted air conditioning unit assembly is provided, including a ducted air conditioning unit body 5, an electrical control box 7, and the aforementioned filter structure. Both the filter structure and the electrical control box 7 are located on the outer wall of the ducted air conditioning unit body 5 and can be connected to the ducted air conditioning unit body 5 via fasteners such as bolts or screws. The filter structure can communicate with the return air inlet of the ducted air conditioning unit body 5. Furthermore, it should be noted that this ducted air conditioning unit assembly possesses all the beneficial effects of the filter structure, which will not be elaborated further in this disclosure.

[0044] In embodiments of this disclosure, such as Figure 5As shown, the filter structure can be installed on the side or bottom of the duct unit body 5. The specific installation position of the filter structure can be adjusted adaptively according to the different specifications of the duct unit body 5. For example, the filter structure can be installed on the side of the duct unit body 5, while the electrical control box 7 can be installed at the bottom of the duct unit body 5. That is, the electrical control box 7 and the filter structure can be installed on two adjacent sides of the duct unit body 5, respectively. In this case, the wire harness inside the filter structure passes through the wire passage structure 2 from the filter housing 1 and extends along the outer surface of the duct unit body 5 until it connects with the electrical control box 7.

[0045] The electrical control box 7 may include a wiring hole 71, with the wiring structure 2 positioned close to the wiring hole 71. This means that the wiring harness of the sensor 8 in the filter housing 1, after passing through the wiring structure 2 to the outside of the filter housing 1, can enter the wiring hole 71 of the electrical control box 7 in the shortest possible distance, thereby connecting to the electrical control box 7. This further reduces the length of the wiring harness, allowing the filter structure, whether located on the side or bottom of the duct unit body 5, to be connected to the electrical control box 7 via a shorter wiring harness.

[0046] In summary, this disclosure exemplarily illustrates the connection method between the filter structure and the air duct body 5.

[0047] A filter structure can be installed on the side of the duct unit body 5, and an electrical control box 7 can be installed at the bottom. When the wiring harness of the sensor 8 in the mounting chamber 4 of the lower cover 12 is connected to the electrical control box 7, the operator can first bring the wiring harness close to the limiting opening 222, allowing the wiring harness to move along the guide surface 3 towards the limiting opening 222. The operator can then press the wiring harness outside the limiting opening 222 to make it snap into the limiting groove 221. At this time, the limiting groove 221 can restrict the movement of the wiring harness, so that when the upper cover 11 is connected to the lower cover 12, The wiring harness is in a relatively stable state, which facilitates the wire passage hole 21 on the upper cover 11 corresponding to the limiting groove 221. After the upper cover 11 and the lower cover 12 are connected, the wiring harness can also pass through the wire passage hole 21. This allows the wiring harness of the sensor 8 to stably pass out from the filter housing 1 and extend along the side wall outside the air duct body 5, and finally connect to the electrical control box 7. The wire passage hole 21 on the upper cover 11 and the limiting part 22 on the lower cover 12 are both located on the side close to the electrical control box 7, which can reduce the length of the wiring harness and facilitate the connection of the wiring harness to the electrical control box 7. Based on this, the filter structure disclosed herein has a wire-passing structure 2 on the side of the filter housing 1 near the electrical control box 7, so that the wire harness inside the filter structure can be connected to the electrical control box 7 from the outside of the filter structure through the wire-passing structure 2, which facilitates the wiring operation of the staff; in addition, since the wire-passing structure 2 is close to the electrical control box 7, the length of the wire harness can also be reduced to a certain extent, thereby reducing or even avoiding the situation where the wire harness is tangled together due to excessive length. Based on this, the disassembly and assembly efficiency of the duct unit assembly is improved.

[0048] The preferred embodiments of this disclosure have been described in detail above with reference to the accompanying drawings. However, this disclosure is not limited to the specific details of the above embodiments. Within the scope of the technical concept of this disclosure, various simple modifications can be made to the technical solutions of this disclosure, and these simple modifications all fall within the protection scope of this disclosure.

[0049] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, this disclosure will not describe the various possible combinations separately.

[0050] Furthermore, various different embodiments of this disclosure can be combined in any way, as long as they do not violate the spirit of this disclosure, they should also be regarded as the content disclosed in this disclosure.
