Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an installation structure for cabinet air conditioners. Background Technology

[0002] In current cabinet air conditioner designs, the casing of a cabinet air conditioner includes a front frame and a rear frame. The front frame and the rear frame together form an opening at the top. To meet diverse air supply needs and optimize air outlet performance, a drive unit and an exhaust unit are installed inside the casing. In cooling mode, the drive unit pushes the exhaust unit out of the opening at the top of the air conditioner casing, making the exhaust outlet of the exhaust unit exposed upwards, thereby increasing the air supply height of the air conditioner and extending the air supply distance of the cold air.

[0003] Chinese utility model patent with publication number CN210861609U discloses an air duct component for an air conditioner and an air conditioner having the same, including a second air outlet frame, a second component and a drive component. The second component has a third air supply duct. The second component is disposed inside the second air outlet frame, so that the third air supply duct communicates with the inner cavity of the second air outlet frame. The drive component is connected to the second component to drive the second component to move up and down relative to the second air outlet frame, so that at least a portion of the outlet of the third air supply duct is exposed above the second air outlet frame.

[0004] However, with the continuous increase in air conditioning energy efficiency standards regarding APF (Annual Performance Factor), the area of ​​the air inlet needs to be expanded accordingly. The rear frame typically uses a U-shaped cross-section design. Since the air inlet is located on the rear frame, the increased area of ​​the inlet significantly weakens the structural strength of the rear frame, easily leading to deformation at the top of the rear frame. This, in turn, causes changes in the opening size. During the rising process, the exhaust components will rub against or interfere with the opening at the top of the casing, ultimately leading to wear or jamming of the exhaust components. Utility Model Content

[0005] To address the technical problem that the rear frame of existing air conditioners is prone to deformation, leading to wear or jamming between the exhaust components and the top opening of the casing, this utility model provides an installation structure for cabinet air conditioners.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An installation structure for a cabinet air conditioner includes a housing and an air outlet assembly. The housing includes a front frame and a rear frame, which are arranged together and form an opening at the top of the housing. The air outlet assembly is disposed inside the upper part of the housing and includes a drive component, an exhaust component, and a mounting base. The drive component is mounted on the mounting base and is connected to the exhaust component. The exhaust component has an internal air duct. The drive component drives the exhaust component to move up and down relative to the opening so that at least a portion of the air duct outlet is exposed above the opening. A bracket is fixedly provided on the side of the mounting base facing the rear frame. The bracket has a first mating surface that matches the shape of the inner side of the rear frame. The first mating surface is fitted and fixed to the inner side of the rear frame.

[0008] Furthermore, the top of the mounting base is provided with a mounting slot, in which both the drive component and the exhaust component are installed. The drive component can push the exhaust component to move up and down within the mounting slot.

[0009] Furthermore, an evaporator is installed inside the casing, with an air outlet at the top of the evaporator. The mounting groove extends through to the bottom of the mounting base and is connected to the air outlet.

[0010] Furthermore, the bracket is provided with a mounting post having screw holes, the fixing seat is provided with a mounting part, the mounting part is provided with a corresponding mating hole, and also includes a screw, the tail of the screw passes through the mating hole and is threaded into the threaded hole, and the head of the screw presses against the mounting part.

[0011] Furthermore, it also includes a particulate matter sensor, a carbon dioxide sensor, and a TVOC sensor. The bracket has a groove on the side facing the rear frame for mounting the particulate matter sensor, carbon dioxide sensor, and TVOC sensor, and the rear frame has a detection port at the position corresponding to the groove.

[0012] Furthermore, there are three grooves arranged side by side with intervals, namely the first groove, the second groove, and the third groove. The particulate matter sensor is installed in the first groove, the carbon dioxide sensor is installed in the second groove, and the TVOC sensor is installed in the third groove.

[0013] Furthermore, both the first and third grooves are provided with limiting posts having screw holes, and the particulate matter sensor and TVOC sensor are provided with corresponding mounting holes. The screws are also included, with the tail of the screw passing through the mounting hole and threaded into the threaded hole, and the head of the screw pressing the particulate matter sensor and TVOC sensor.

[0014] Furthermore, the carbon dioxide sensor has a protrusion on its periphery, and the second groove has a corresponding elastic locking protrusion on its side wall, which engages with the protrusion.

[0015] Furthermore, the rear frame is provided with a positioning protrusion, and the bracket is provided with a corresponding positioning hole, with the positioning protrusion and the positioning hole being inserted and matched.

[0016] Furthermore, the bracket has a threaded hole at the top and a corresponding screw through hole on the rear frame, and also includes a screw. The tail of the screw passes through the screw through hole and is threaded into the threaded hole, while the head of the screw presses against the rear frame.

[0017] The beneficial effects of this utility model are:

[0018] This invention features a bracket fixed to the side of the mounting base facing the rear frame. The bracket has a first mating surface that matches the shape of the inner side of the rear frame, and this first mating surface is tightly fitted and fixed to the inner side of the rear frame. The first mating surface's shape matching and tight fit with the inner side of the rear frame effectively supports the top of the rear frame. Through the bracket's reinforcement of the rear frame's rigidity, deformation of the rear frame is effectively suppressed, ensuring a safe movement clearance between the exhaust component and the rear frame during the extension of the exhaust component's opening, effectively avoiding the risk of wear or interference. Furthermore, this design maintains the original thickness of the rear frame while significantly increasing the air inlet area, yet the rear frame structure still possesses strong rigidity and strength.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the present invention will be further described below with reference to the accompanying drawings.

[0029] First, it should be stated that the technical solutions of the embodiments of this application are clearly and completely described. The described embodiments are only some of the embodiments of this application, and not a limitation of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0030] In the description of this utility model, it should be understood that the terms "first", "second", "upper", "lower", "left", "right", "inner", "outer", "axial" or "radial" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and are not intended to indicate or imply that the device or element referred to must have a specific orientation structure and operation. Therefore, they should not be construed as limitations on this utility model.

[0031] Reference Figure 1 and Figure 8 This utility model provides an installation structure for cabinet air conditioners.

[0032] like Figure 1 and Figure 3 As shown, the installation structure for a cabinet air conditioner includes a housing and an air outlet assembly. The housing includes a front frame 1 and a rear frame 2, which are arranged together and form an opening 3 at the top of the housing. The air outlet assembly is located inside the upper part of the housing and includes a drive unit (not shown), an exhaust unit 4, and a mounting base 7. The drive unit is mounted on the mounting base 7 and is connected to the exhaust unit 4. The exhaust unit 4 has an air duct (not shown) inside. The drive unit drives the exhaust unit 4 to move up and down relative to the opening 3 so that at least a portion of the outlet (not shown) of the air duct is exposed above the opening 3. The mounting base 7 is fixedly provided with a bracket 5 on the side facing the rear frame 2. The bracket 5 has a first mating surface 6 that matches the shape of the inner side of the rear frame 2. The first mating surface 6 is fitted and fixed to the inner side of the rear frame 2.

[0033] For the drive components, air ducts, and outlets not shown in this embodiment, those skilled in the art, based on the background technology of this application or basic knowledge of the relevant field, should understand how they are set up and implemented. The drive components can be commercially available lifting mechanisms, such as electric push rod mechanisms, hydraulic cylinder mechanisms, pneumatic cylinder mechanisms, or mechanical structures using gears and racks, which will not be listed here one by one.

[0034] like Figure 1 As shown, for the air duct and outlet inside the exhaust component 4, the air duct inlet can be directly connected to the air outlet 9 of the evaporator 8 through a pipe; alternatively, a fixed base 7 can be installed below the exhaust component 4, with an installation groove on the top of the fixed base 7 extending to the bottom of the fixed base 7 and connected to the air outlet 9 of the evaporator 8. Both the drive component and the exhaust component 4 are installed in the installation groove. The drive component can push the exhaust component 4 to move up and down in the installation groove. At this time, one end of the pipe is connected to the air outlet 9 of the evaporator 8, and the other end passes through the installation groove and is connected to the air inlet of the exhaust component 4; alternatively, the fixed base 7 can be directly installed at the air outlet 9 of the evaporator 8, and the exhaust component 4 is tightly fitted in the installation groove. This eliminates the need for pipe installation, and the air discharged from the air outlet 9 of the evaporator 8 flows directly to the air inlet of the exhaust component 4 through the installation groove at the bottom of the fixed base 7.

[0035] like Figure 1 As shown, for the exhaust component 4, for aesthetic and sealing purposes, the top outline of the exhaust component 4 is close in size to the opening 3 of the housing, and a small installation gap, such as 0.5mm-2mm, is left between the exhaust component 4 and the opening 3. The opening 3 at the top of the housing is formed by the front frame 1 and the rear frame 2. If the rear frame 2 deforms, the size of the opening 3 of the housing will change, which will cause the installation gap between the exhaust component 4 and the opening 3 to shrink or disappear. This will cause the exhaust component 4 to rub against or interfere with the opening 3 at the top of the housing during the lifting process, ultimately leading to wear or jamming of the exhaust component 4.

[0036] The bracket 5 has a first mating surface 6 that matches the shape of the inner side of the rear frame 2. The rear frame 2 is typically a U-shaped frame with a U-shaped arc surface on its inner side. The bracket 5 is not required to be in full contact with the entire inner surface of the rear frame 2. Preferably, the bracket 5 is only required to be in contact with the arc surface of the top area of ​​the rear frame 2 to maintain the specific shape of the U-shaped frame and effectively prevent deformation. The first mating surface 6 is fixed to the inner side of the rear frame 2 by screws or bolts, or by clips.

[0037] like Figure 2 , Figure 3 and Figure 4As shown, this utility model has a bracket 5 fixedly installed on the side of the fixed base 7 facing the rear frame 2. The bracket 5 has a first mating surface 6 that matches the shape of the inner side of the rear frame 2. The first mating surface 6 is fitted and fixed to the inner side of the rear frame 2. The first mating surface 6 matches the shape of the inner side of the rear frame 2 and is tightly fitted and fixed, forming an effective support for the top of the rear frame 2. Through the rigid reinforcement of the rear frame 2 by the bracket 5, the deformation of the rear frame 2 is effectively suppressed, ensuring that a safe movement gap is always maintained between the exhaust component 4 and the rear frame 2 during the process of the exhaust component 4 extending out of the opening 3, effectively avoiding the risk of wear or interference.

[0038] like Figure 1 and Figure 2 As shown, in some embodiments, the top of the fixed base 7 has a mounting groove, and both the drive component and the exhaust component 4 are installed in the mounting groove. The drive component can push the exhaust component 4 to move up and down within the mounting groove. The fixed base 7 is connected and fixed to the rear frame 2 by the bracket 5, and the exhaust component 4 can move up and down relative to the fixed base 7. Regarding the connection between the air inlet of the exhaust component 4 and the air outlet 9 of the evaporator 8, it can be achieved through a pipe, or the mounting groove can extend to the bottom of the fixed base 7 and connect with the air outlet 9 of the evaporator 8. The air inlet of the exhaust component 4 is sealed to the mounting groove, thus achieving connection, reducing additional space occupation, and resulting in a compact structure. The height of the exhaust component 4 can be controlled by the drive component, flexibly adjusting the air outlet angle and improving air supply comfort.

[0039] like Figure 1 As shown, in some embodiments, an evaporator 8 is provided inside the housing, the top of the evaporator 8 has an air outlet 9, and the mounting groove extends through to the bottom of the fixing base 7 and is connected to the air outlet 9.

[0040] like Figure 2 As shown, in some embodiments, regarding how the bracket 5 is fixed to the fixing base 7, preferably, the bracket 5 is provided with a mounting post 10 having screw holes, and the fixing base 7 is provided with a mounting part, which is provided with a corresponding mating hole and also includes a screw. The tail of the screw passes through the mating hole and is threaded into the threaded hole, and the head of the screw presses against the mounting part. The screw locking provides mechanical stability and is not easy to loosen due to vibration. In addition, it can be integrally molded and connected, or it can be fixed by snap-fit ​​connection, or it can be provided with a clamping or limiting structure to fix the bracket 5 to the fixing base 7.

[0041] like Figure 7 and Figure 8As shown, in some embodiments, a particulate matter sensor 11, a carbon dioxide sensor 12, and a TVOC sensor 13 are also included. The bracket 5 has a groove on the side facing the rear frame 2 for mounting the particulate matter sensor 11, carbon dioxide sensor 12, and TVOC sensor 13. A detection port 14 is provided on the rear frame 2 at a position corresponding to the groove. The groove design ensures uniform assembly and wiring of the particulate matter sensor 11, carbon dioxide sensor 12, and TVOC sensor 13, avoiding differences in detection data at different locations. The number of grooves can be one or three. When using one groove, it is designed to be relatively large, and all three sensors are installed within it with a certain distance between them. Alternatively, three grooves can be provided, with different sensors installed independently.

[0042] The TVOC sensor 13 is a device used to detect the concentration of volatile organic compounds in the air. It can detect various harmful gases such as formaldehyde, benzene, ammonia, and xylene, which can affect human health.

[0043] like Figure 7 and Figure 8 As shown, in some embodiments, there are three grooves arranged side by side with intervals, namely a first groove 15, a second groove 16, and a third groove 17. The particulate matter sensor 11 is installed in the first groove 15, the carbon dioxide sensor 12 is installed in the second groove 16, and the TVOC sensor 13 is installed in the third groove 17. The three grooves are arranged side by side to avoid circuit interference between different sensors.

[0044] like Figure 7 and Figure 8 As shown, in some embodiments, both the first groove 15 and the third groove 17 are provided with limiting posts 18 having screw holes. The particulate matter sensor 11 and the TVOC sensor 13 are each provided with corresponding mounting holes, and screws are also included. The tail of the screw passes through the mounting hole and is threaded into the threaded hole, while the head of the screw presses against the particulate matter sensor 11 and the TVOC sensor 13. A rubber washer can be added to the top of the limiting post 18 to buffer the stress during screw tightening. Thermally conductive adhesive can also be applied to the back of the particulate matter sensor 11 and the TVOC sensor 13 for direct bonding and fixation to the bottom of the groove.

[0045] like Figure 7 and Figure 8 As shown, in some embodiments, a protrusion 19 is provided on the periphery of the carbon dioxide sensor 12, and a corresponding elastic locking protrusion 20 is provided on the sidewall of the second groove 16. The elastic locking protrusion 20 engages with the protrusion 19. This allows for quick assembly without tools; installation can be completed simply by pressing, improving production efficiency. In addition, it also improves the convenience of maintenance, as the elastic locking protrusion 20 can be manually disassembled for easy calibration or replacement of the carbon dioxide sensor 12.

[0046] like Figure 5 and Figure 6 As shown, in some embodiments, the rear frame 2 is provided with a positioning protrusion 21, and the bracket 5 is provided with a corresponding positioning hole 22. The positioning protrusion 21 and the positioning hole 22 are inserted into each other. The insertion and engagement of the positioning protrusion 21 and the positioning hole 22 has a positioning function, defining a unique installation position, avoiding manual reverse installation, and can also withstand some shearing force, reducing the load on the screws.

[0047] like Figure 3 and Figure 4 As shown, in some embodiments, the bracket 5 is preferably installed and fixed on the rear frame 2 with a threaded hole at the top and a corresponding screw through hole on the rear frame 2. The bracket 5 also includes a screw, with the tail of the screw passing through the screw through hole and threadedly engaging with the threaded hole, and the head of the screw pressing against the rear frame 2.
