Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a fresh air module and an air conditioning device. Background Technology

[0002] A fresh air module is a ventilation device used to improve indoor air quality. In related technologies, the electrical control box of a fresh air module adopts an independent box structure design, meaning it is manufactured as a separate sheet metal part and then assembled and fixed to the side panel of the fresh air module. While this split design achieves encapsulation and protection of the circuit control unit, it leads to higher manufacturing costs and lower efficiency in overall assembly and subsequent operation and maintenance. Utility Model Content

[0003] This utility model is based on the inventor's discovery and understanding of the following facts and problems:

[0004] Independent electrical control boxes require the development of dedicated molds, resulting in a significant increase in the number of molds and processing steps. This is especially problematic in the production of multi-model products, where mold development costs are high and material utilization is low. Furthermore, the electrical control box and side panels need to be stamped, bent, and welded separately, leading to repetitive processing steps and increased labor costs.

[0005] The assembly process requires separate assembly of the fresh air casing and the electrical control box. Then, the electrical control box is assembled and fixed to the side panel of the fresh air module. The process is cumbersome and the assembly efficiency is low.

[0006] Independent electrical control boxes occupy a large space, which limits the compact design of fresh air modules. Furthermore, multiple components need to be disassembled for later maintenance, resulting in high operational complexity and low maintenance efficiency.

[0007] This utility model aims to at least partially solve one of the technical problems in the related art.

[0008] Therefore, embodiments of this utility model propose a fresh air module, which has the advantages of low manufacturing cost and high assembly and maintenance efficiency.

[0009] An embodiment of this utility model also proposes an air conditioning device.

[0010] The fresh air module of this utility model embodiment includes a housing, a centrifugal impeller, and an electrical control box. The housing includes a first side plate, which includes a first part and a second part. The first part is provided with a duct interface. The centrifugal impeller is disposed inside the housing, and the axial direction of the centrifugal impeller is parallel to the first part of the first side plate. The electrical control box and the duct interface are arranged at intervals along the length direction of the first side plate. The width direction of the electrical control box is parallel to the length direction of the first side plate, and the length direction of the electrical control box is parallel to the axial direction of the centrifugal impeller. The electrical control box includes a box body and a box cover, and the box body and the box cover are connected. The second part of the first side plate constitutes a part of the box body.

[0011] According to the fresh air module of this utility model embodiment, the body of the electrical control box and the second part of the first side plate share a sheet metal part, eliminating the need for a separate electrical control box shell. This not only reduces the number of parts and improves structural compactness, but also reduces the need for mold development for the sheet metal part of the electrical control box, thus lowering manufacturing costs. Furthermore, it eliminates the connection process between the electrical control box and the side plate, improving assembly and maintenance efficiency.

[0012] In some embodiments, a second portion of the first side plate is recessed toward the interior of the housing.

[0013] In some embodiments, the first side panel includes a first plate, a second plate, and a third plate connected in sequence.

[0015] In some embodiments, the portion of the second side panel that constitutes the box body is L-shaped, and this portion includes a fourth plate and a fifth plate connected together, the fourth plate being parallel to the second plate and the fifth plate being flush with the first plate.

[0016] In some embodiments, the third plate has a right-angle flange on the side away from the top plate, the lid is L-shaped, and the lid includes a sixth plate and a seventh plate connected together. The sixth plate is flush with and connected to the fifth plate, and the seventh plate is flush with and connected to the flange of the third plate.

[0017] In some embodiments, the first side panel, the second side panel, and the top panel together constitute the box body.

[0018] In some embodiments, the electrical control box contains an electrical control board, the electrical control board has a plug-in portion, and the third plate has a plug-in slot that mates with the plug-in portion.

[0019] In some embodiments, the electronic control board is provided with a limiting portion, and the second plate is provided with a limiting protrusion that contacts the limiting portion. The limiting protrusion is located on the side of the limiting portion away from the third plate.

[0020] In some embodiments, at least one of the electronic control board and the third plate is provided with a positioning part, and the other of the electronic control board and the third plate is provided with a positioning groove that cooperates with the positioning part.

[0021] In some embodiments, the flange of the third plate is provided with screw holes, and the control board is provided with a stop portion, the stop portion and the projection of the screw holes along the length direction of the control box coincide.

[0022] In some embodiments, at least one of the fifth plate and the sixth plate is provided with a wiring channel outlet, and the wiring channel outlet corresponds to the wiring channel of the electronic control board.

[0041] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] The fresh air module of this utility model embodiment is described below with reference to the accompanying drawings.

[0043] like Figures 1 to 11 As shown, the fresh air module of this utility model embodiment includes a housing 1, a centrifugal impeller 2, and an electrical control box 3. The housing 1 is the overall outer shell of the fresh air module, and is generally cuboid in shape. The housing 1 is surrounded by side plates, a top plate 12, and a bottom plate 14, and all plates of the housing 1 are made of sheet metal. Among them, the side plates around the housing 1 include a first side plate 11 (e.g., Figure 1 The front side panel of the first side panel 11 includes a first part (such as the front side panel of the first side panel 11). Figure 1 The right half of the middle) and the second part (such as Figure 1 The left half of the middle part), the first part is provided with duct interface 101, which is used to connect the new air duct.

[0044] The centrifugal impeller 2 is the main structure of the fresh air module's fan. The centrifugal impeller 2 is housed within the casing 1, and its axial direction is parallel to the first portion of the first side plate 11. The electrical control box 3 and the duct interface 101 are arranged at intervals along the length of the first side plate 11. The width of the electrical control box 3 is parallel to the length of the first side plate 11, and its length is parallel to the axial direction of the centrifugal impeller 2. In other words, the electrical control box 3 extends not only along the side plate of the fresh air duct but also along the air inlet direction of the fan.

[0045] It should be noted that the length direction of the first side plate 11 is as follows: Figure 1 The left and right directions within the box. The control box 3 has length, width, and thickness; the length direction of the control box 3 is as follows: Figure 1 The vertical direction of the control box 3 and the width direction are as follows: Figure 1 In the left and right direction, the thickness direction of the electrical control box 3 is as follows: Figure 1 The front and back directions in the middle.

[0046] The electrical control box 3 includes a box body 31 and a box cover 32, with the box body 31 connected to the box cover 32. The second part of the first side plate 11 forms part of the box body 31. The box cover 32 is an independent sheet metal part, which is detachably connected to the box body 31 by screws or clips, facilitating the disassembly and maintenance of the internal components of the electrical control box 3.

[0047] In this embodiment of the fresh air module, the body 31 of the electrical control box 3 and the second part of the first side plate 11 share a sheet metal part, eliminating the need for a separate outer shell for the electrical control box 3. This not only reduces the number of parts and improves structural compactness but also reduces the need for mold development for the sheet metal part of the electrical control box 3, thus lowering manufacturing costs. Furthermore, it eliminates the connection process between the electrical control box 3 and the side plate, improving assembly and maintenance efficiency.

[0048] In some embodiments, such as Figures 2 to 5 As shown, the second part of the first side plate 11 is recessed towards the interior of the housing 1.

[0049] Understandably, by embedding the electrical control box 3, the protruding structure of the external electrical control box 3 is avoided, thus reducing the overall thickness of the fresh air module, increasing the maintenance space on the front of the fresh air module, and improving the convenience of maintenance. Furthermore, embedding the electrical control box 3 improves the overall aesthetics of the fresh air module layout.

[0050] For example, the second part of the first side plate 11 can adopt a stepped recessed structure, with the bottom of the recess and the step surface being flat, allowing for a larger usable space.

[0051] Specifically, such as Figures 1 to 5 As shown, the first side panel 11 includes a first plate 111, a second plate 112, and a third plate 113 connected in sequence. The first plate 111 and the third plate 113 are parallel and staggered in the front-to-back direction. The second plate 112 is perpendicular to both the first plate 111 and the third plate 113. The first plate 111 is the first part of the first side panel 11 and is used to install the fresh air duct. The second plate 112 and the third plate 113 are the second parts of the first side panel 11. The second plate 112 constitutes the right side panel of the box 31 of the electrical control box 3, and the third plate 113 constitutes the rear side panel of the box 31 of the electrical control box 3.

[0052] In some embodiments, such as Figures 1 to 5 As shown, the housing 1 also includes a top plate 12 and a second side plate 13. The top plate 12 is connected to the first side plate 11, and a portion of the top plate 12 forms part of the box body 31. The top plate 12 is a single square plate, and the front edge of the top plate 12 is connected to the upper edge of the first plate 111. The portions of the top plate 12 located to the left of the second plate 112 and to the front of the third plate 113 form the upper side plate of the box body 31.

[0053] The second side panel 13 is connected to the first side panel 11 and the top panel 12, and a portion of the second side panel 13 forms part of the box body 31. Specifically, the portion of the second side panel 13 that forms part of the box body 31 is L-shaped, and this portion includes a connected fourth panel 131 and a fifth panel 132. The fourth panel 131 is parallel to the second panel 112, and the fifth panel 132 is flush with the first panel 111. The fourth panel 131 forms the left side panel of the box body 31.

[0054] It is important to note that a connector is required on the fresh air module for secure mounting. Since the cover 32 serves as the front cover of the electrical control box 3 and needs to be opened during maintenance, it is inconvenient to mount the connector on the front of the fresh air module on the cover 32. Therefore, the cover 32 only covers a portion of the front of the box body 31, with the remaining portion covered by the fifth plate 132 formed by bending the second side plate 13. This allows the connector on the front of the fresh air module to be mounted on the fifth plate 132, improving the design's rationality.

[0055] In some embodiments, such as Figures 1 to 5 As shown, the third plate 113 has a right-angle flange 1131 on the side away from the top plate 12. This flange 1131 is folded away from the interior of the housing 1, that is, folded forward, and the flange 1131 is used to form the lower side plate of the box 31.

[0056] To facilitate maintenance of the components inside the fresh air module, the bottom plate 14 of the housing 1 is usually removed. If a portion of the bottom plate 14 of the housing 1 is used to form the lower side plate of the box 31, the components inside the electrical control box 3 will also be exposed during the removal and maintenance of the bottom plate 14, increasing the risk of damage to the components inside the electrical control box 3.

[0057] Specifically, the lid 32 is L-shaped and includes a sixth plate 321 and a seventh plate 322 connected to each other. The sixth plate 321 is flush with and connected to the fifth plate 132, and the seventh plate 322 is flush with and connected to the flange 1131 of the third plate 113. The sixth plate 321 is used to cover the front opening of the box body 31, and the seventh plate 322 is used to compensate for the gap on the lower side of the box body 31 between the flange 1131 of the third plate 113 and the sixth plate 321.

[0058] Thus, the first side plate 11, the second side plate 13 and the top plate 12 together constitute the box 31, further increasing the number of sheet metal parts shared between the box 31 of the electrical control box 3 and the shell 1 of the fresh air module, thereby further improving the overall structural compactness and reducing manufacturing costs.

[0059] In some embodiments, such as Figures 1 to 11 As shown, the electrical control box 3 houses the electrical control board 4. The electrical control board 4 is the intelligent hub of the fresh air module. As the core component of the electrical control box 3, it enables the fresh air module to operate automatically, efficiently, and safely through functions such as power supply control, environmental response, safety protection, and intelligent interaction. With the integrated electrical control box 3 design, its performance and reliability are further optimized.

[0060] like Figure 6 , Figure 9 and Figure 10 As shown, the control board 4 has a plug-in part 41, and the third plate 113 has a plug-in groove 1132 that mates with the plug-in part 41. By providing the plug-in part 41 (such as a protrusion, snap-fit, or guide rib) on the control board 4 to mate with the plug-in groove 1132 of the third plate 113, screwless fixing between the control board 4 and the third plate 113 is achieved. The screwless structure eliminates the need for reserved space for tool operation, further adapting to the compact design of the fresh air module.

[0061] The traditional screw tightening process is eliminated, and the electrical control board 4 can be installed in just two steps: plugging in and aligning, then pressing / sliding, thus shortening assembly time. The elimination of screws, nuts, washers, and other fasteners reduces component complexity. Maintenance requires no screwdrivers or other tools; the electrical control board 4 can be removed simply by plugging in or pressing the clips, improving maintenance efficiency. Furthermore, the plug-in structure has a built-in limit function to prevent the risk of screws being lost or falling into the equipment after removal.

[0062] For example, guide ribs are provided on the back of the control board 4, and a sliding groove is opened at the corresponding position of the third plate 113, so that the locking is achieved by sliding. Alternatively, barbed elastic buckles are provided on both sides of the control board 4, and a rectangular slot is opened in the third plate 113. The inner wall of the slot is provided with a locking groove. Pressing the control board 4 causes the buckles to deform and embed into the slot, and locking is achieved by the rebound force.

[0063] like Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the control board 4 is provided with a limiting part 42, and the second plate 112 is provided with a limiting protrusion 1121 that contacts the limiting part 42. The limiting protrusion 1121 is located on the side of the limiting part 42 away from the third plate 113. The synergistic effect of the limiting part 42 and the limiting protrusion 1121 is to supplement and strengthen the plug-in structure, and to provide multi-dimensional constraint and anti-detachment function for the control board 4.

[0064] The plug-in structure mainly provides a basic fixation for the electronic control board 4, while the limiting part 42 (such as a groove or boss) and the limiting protrusion 1121 (such as a claw or stop) form a secondary lock, restricting the electronic control board 4 from moving in the front-to-back direction during vibration or transportation, so that the electronic control board 4 can achieve mechanical performance comparable to screw fixing in a screwless solution, while retaining the advantage of quick assembly and disassembly.

[0065] like Figure 5 and Figure 6 As shown, at least one of the electronic control board 4 and the third plate 113 is provided with a positioning part 43, and the other of the electronic control board 4 and the third plate 113 is provided with a positioning groove 1133 that cooperates with the positioning part 43. Specifically, the electronic control board 4 is provided with both the positioning part 43 and the positioning groove 1133, and the third plate 113 is also provided with both the positioning part 43 and the positioning groove 1133.

[0066] The initial engagement of the positioning part 43 (such as a guide pin or protrusion) with the positioning groove 1133 defines the approximate position of the electronic control board 4 and the third plate 113, providing basic guidance for the subsequent installation of the electronic control board 4. After basic guidance and positioning, the insertion part 41 and the insertion groove 1132 precisely cooperate to eliminate any remaining positional deviations. Finally, the limiting part 42 and the limiting protrusion 1121 restrict multidimensional displacement, completing the fixation of the electronic control board 4.

[0067] Therefore, through the systematic design of positioning, insertion, and limiting, the screw fixing of the electronic control board 4 is optimized into tool-free rapid assembly, thereby improving the assembly efficiency and installation fault tolerance of the electronic control board 4.

[0068] In some embodiments, such as Figure 9 and Figure 11As shown, the flange 1131 of the third plate 113 is provided with screw holes 1134, and the control board 4 is provided with a stop part 44. The projection of the stop part 44 and the screw hole 1134 along the length direction of the control box 3 coincides.

[0069] The stop portion 44 is located between the circuit layer of the control board 4 and the screw hole 1134, forming a rigid protective barrier (such as a metal baffle or a thickened insulation layer). When the screw is screwed in, the stop portion 44 prevents the screw from going too deep, preventing it from penetrating the control board 4 or pressing on the wiring below. Furthermore, based on the screwless fixing of the control board 4 (plug-in / limiting scheme), it further solves the derivative risks of screw assembly of the housing 31.

[0070] In some embodiments, such as Figures 1 to 4 As shown, at least one of the fifth plate 132 and the sixth plate 321 is provided with a wiring channel outlet 1321, and the wiring channel outlet 1321 corresponds to the wiring channel of the electronic control board 4.

[0071] Specifically, both the fifth plate 132 and the sixth plate 321 have notches at their joints. These notches together form the cable tray outlet 1321. The extended wall of the cable tray of the control board 4 contacts the fifth plate 132 and the sixth plate 321, further limiting the movement of the control board 4 by the fifth plate 132 and the sixth plate 321. Furthermore, the cable tray outlet 1321 also coordinates with the air outlet function of the cable tray of the control board 4.
