Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a window air conditioner. Background Technology

[0002] A window air conditioner is an integrated air conditioning unit that can be installed in a wall window or other dedicated mounting opening. Its structure integrates the indoor and outdoor units into one unit. The indoor unit has an indoor air inlet and an indoor air outlet. When the indoor fan is running, indoor air enters the casing through the air inlet, exchanges heat with the indoor heat exchanger, and is then returned to the room through the air outlet. The outdoor unit has an outdoor air inlet and an outdoor air outlet. When the outdoor fan is running, outdoor air enters the casing through the air inlet, exchanges heat with the outdoor heat exchanger, and is then exhausted to the outside through the air outlet.

[0003] In the process of developing the existing technology, the inventors discovered that: Traditional window air conditioners concentrate key components such as the compressor and fan in a single casing, generating significant noise during operation and noticeably impacting the user experience. Moreover, due to the size constraints of window installation space, the size of the evaporator and condenser, as well as the heat exchange area, are generally small, resulting in low overall heat exchange efficiency.

[0004] Therefore, this application aims to propose a window air conditioning technology solution that reduces operating noise and improves heat exchange efficiency, so as to solve the problems of high noise and low efficiency in the prior art. Utility Model Content

[0005] This utility model proposes a window air conditioner technology solution that reduces operating noise and improves heat exchange efficiency, in order to solve the problems of high noise and low efficiency in the existing technology.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A window air conditioner is provided, including an indoor unit unit, an outdoor unit unit, a connecting pipe assembly connecting the indoor unit unit and the outdoor unit unit, and telescopic bracket assemblies disposed on both sides of the window to support the indoor unit unit and the outdoor unit unit. The telescopic bracket assembly includes an outdoor unit main bracket unit, an indoor unit main bracket unit, and a connecting frame unit that connects the outdoor unit main bracket unit and the indoor unit main bracket unit. The connecting frame unit is telescopic.

[0007] In a preferred embodiment of this utility model, the connecting frame unit includes two U-shaped connecting frames 1 connected to the outdoor unit main bracket unit and two U-shaped connecting frames 2 connected to the indoor unit main bracket unit and engaged with the two U-shaped connecting frames 1. The two side walls of the U-shaped connecting frames 1 and 2 are respectively provided with a plurality of connecting holes, which are used to determine the position between the U-shaped connecting frames 2 connected to the indoor unit main bracket unit and the U-shaped connecting frames 1 connected to the outdoor unit main bracket unit, and then connect and lock them by passing butterfly bolts through the connecting holes at the opposite positions of the U-shaped connecting frames 1 and 2.

[0008] In a preferred embodiment of the present invention, the indoor unit includes a cross-flow fan, an evaporator one and an evaporator two, and a drip tray.

[0009] In a preferred embodiment of the present invention, the water receiving tray includes an air inlet area and a water receiving area, and the bottom of the intersection position of the first evaporator and the second evaporator corresponds to the water receiving area of ​​the water receiving tray.

[0010] In a preferred embodiment of the present invention, the outdoor unit includes an axial flow fan, a condenser, a compressor, an outdoor side water tray, and a water pump.

[0011] In a preferred embodiment of the present invention, the connecting pipe assembly includes a return air hose and a water pump pipe.

[0012] In a preferred embodiment of the present invention, the indoor unit main support unit includes two vertical supports that are perpendicularly connected to two U-shaped connecting frames respectively, an indoor unit support connecting rod is connected between the two vertical supports, and a support connecting rod that is inclined at a preset angle to the side wall of each of the two vertical supports is also connected.

[0013] In a preferred embodiment of this utility model, the indoor unit main support unit includes two vertical supports that are perpendicularly connected to two U-shaped connecting frames, and an indoor unit support connecting rod is connected between the two vertical supports. The two U-shaped connecting frames, the two vertical supports, and the indoor unit support connecting rod are each provided with a number of welding points for welding and covering the indoor unit unit.

[0014] In a preferred embodiment of the present invention, the outdoor unit main support unit includes two L-shaped supports that are perpendicularly connected to two U-shaped connecting frames. The two ends of the L-shaped supports are connected to outdoor unit support reinforcing rods, and a square frame for supporting the outdoor unit unit is erected at the bottom of the two L-shaped supports.

[0015] In a preferred embodiment of this utility model, bolt fixing holes are respectively provided at the positions of the two L-shaped brackets near the two U-shaped connecting brackets, for locking the outdoor unit unit by inserting a screw into the bolt fixing holes.

[0016] The window air conditioner provided in this application has the following beneficial effects: The outdoor and indoor units of the window air conditioner are installed on both sides of the window and supported by a telescopic bracket assembly. This isolates the noise generated by the compressor and fan unit in the outdoor unit. The indoor unit uses a cross-flow fan, which delivers gentle and even air with low noise.

[0017] Furthermore, the indoor unit features a V-shaped arrangement of evaporators one and two, increasing the evaporator area within the space. The optimized condensate collection and airflow path of the drip tray further enhances heat exchange efficiency.

Detailed Implementation

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0021] Please see Figure 1 and Figure 2 The window air conditioner 100 provided in this application includes an indoor unit unit 10, an outdoor unit unit 20, a connecting pipe assembly 30 connecting the indoor unit unit 10 and the outdoor unit unit 20, and telescopic bracket assemblies 40 disposed on both sides of the window to support the indoor unit unit 10 and the outdoor unit unit 20; the telescopic bracket assembly 40 includes an outdoor unit main bracket unit 41, an indoor unit main bracket unit 42, and a connecting frame unit 43 connecting the outdoor unit main bracket unit 41 and the indoor unit main bracket unit 42, and the connecting frame unit 43 is telescopic.

[0022] Specifically, traditional window air conditioners 100 are generally integrated units installed in locations with windows, with one part located indoors and the other outdoors. However, these integrated air conditioners are noisy during operation, resulting in a poor user experience. Based on these issues, this application provides a split-type window air conditioner 100, where the outdoor unit unit 20 is installed on the outdoor unit main support unit 41, and the indoor unit unit 10 is installed on the indoor unit main support unit 42, connected by a connecting bracket unit 43. It can be understood that by installing the outdoor unit unit 20 on the outside of the window, i.e., on the wall, the wall thickness can be used to block the noise of the compressor and fan in the outdoor unit unit 20 from entering the room, thereby reducing noise.

[0023] Furthermore, the telescopic nature of the connecting bracket unit 43 is primarily to accommodate walls of varying thicknesses, allowing it to be precisely fitted into the wall for installation. The connecting bracket unit 43 includes two U-shaped connecting brackets 431 that connect to the outdoor unit main bracket unit 41, and two U-shaped connecting brackets 432 that connect to the indoor unit main bracket unit 42 and engage with the two U-shaped connecting brackets 431. Each of the two side walls of the U-shaped connecting brackets 431 and 432 has several horizontally opened connecting holes 433. These holes are used to determine the position between the U-shaped connecting brackets 432 connected to the indoor unit main bracket unit 42 and the U-shaped connecting brackets 431 connected to the outdoor unit main bracket unit 41. The connecting brackets are then locked in place by butterfly bolts passing through the corresponding connecting holes 433.

[0024] Specifically, the connection hole 433 is mainly used for connecting the U-shaped connecting bracket one 431 and the U-shaped connecting bracket two 432. In a preferred embodiment provided in this application, the U-shaped connecting bracket one 431 has one connection hole 433, and the U-shaped connecting bracket two 432 has several connection holes 433. After determining the position between the U-shaped connecting bracket two 432 connected to the indoor unit main bracket unit 42 and the U-shaped connecting bracket one 431 connected to the outdoor unit main bracket unit 41, the connection hole 433 of the U-shaped connecting bracket one 431 and one of the several connection holes 433 of the U-shaped connecting bracket two 432 are connected by a butterfly bolt to achieve connection locking. In terms of contact for connection, both ends of the U-shaped connecting bracket one 431 also have inwardly extending blocking portions to limit the U-shaped connecting bracket two 432 within the U-shaped connecting bracket one 431.

[0025] Alternatively, the U-shaped connecting bracket 1 431 can be provided with several connecting holes 433, and the U-shaped connecting bracket 2 432 can be provided with several connecting holes 433. After determining the position between the U-shaped connecting bracket 2 432 connected to the indoor unit main bracket unit 42 and the U-shaped connecting bracket 1 431 connected to the outdoor unit main bracket unit 41, at least two butterfly bolts can be passed through the two connecting holes 433 of the U-shaped connecting bracket 1 431 and the corresponding connecting holes 433 of the U-shaped connecting bracket 2 432 to achieve connection locking.

[0026] Furthermore, the connecting frame unit 43 is retractable, such as... Figure 7 As shown, this allows the distance between the telescopic bracket assembly 40 and the wall to be shortened to zero during transportation, reducing the packaging size and increasing the number of containers that can be loaded.

[0027] Furthermore, such as Figure 3As shown, the indoor unit 10 includes a cross-flow fan 11, an evaporator 12 and an evaporator 2 13, and a drip tray 14. The evaporators 12 and 2 13 are arranged in a V-shape in the indoor unit 10, and the cross-flow fan 11 is located between the evaporators 12 and 2 13.

[0028] Specifically, in addition to reducing noise by placing the outdoor unit 20 outdoors through the telescopic bracket assembly 40, this application also improves the selection of the indoor unit 10. By selecting the cross-flow fan 11, the indoor unit 10 emits gentle and uniform air, further reducing noise.

[0029] In addition to reducing noise, the utility model also includes a V-shaped evaporator 12 and an evaporator 23 in the indoor unit 10, which increases the evaporator area in the space and the water tray 14 with air inlet can effectively increase the air conditioning capacity and energy efficiency.

[0030] Furthermore, the water receiving tray 14 includes an air inlet area 141 and a water receiving area 142, with the bottom of the connection position between evaporator 12 and evaporator 2 13 corresponding to the water receiving area 142 of the water receiving tray 14.

[0031] The water collection area 142 at the bottom of evaporator 12 and evaporator 2 13 is used to collect water, and the air inlet area 141 is used to store the condensate left on the evaporators. It should be noted that evaporator 12 and evaporator 2 13 are arranged in a V-shape inside the indoor unit unit 10, and it should be ensured that the condensate on evaporator 12 and evaporator 2 13 flows into the water collection area 142 of the water collection tray 14.

[0032] It should also be noted that the water tray 14 in the indoor unit 10 can be made into an independent component or integrated with the cross-flow duct.

[0033] Furthermore, such as Figure 4 As shown, the outdoor unit 20 includes an axial fan 21, a condenser 22, a compressor, an outdoor side water tray 24, and a water pump.

[0034] Specifically, in addition to the usual fan bracket, fan, and axial fan impeller (not shown in the figure), the axial fan 21 in the outdoor unit 20 also has a water-slinging ring 211 on the axial fan impeller. The axial fan 21, condenser 22, and compressor (not shown in the figure) are all located in the outdoor unit 20. The outdoor side water tray 24 is used to support the components of the outdoor unit 20 and store the condensate pumped from the indoor side. It should be noted that the two methods of using a water pump (not shown in the figure) to pump the condensate from the indoor side to the outdoor side and let it drip from the top of the condenser 22, and using the water-slinging ring 211 on the axial fan impeller of the axial fan 21 to throw the condensate in the outdoor side water tray onto the condenser 22, effectively utilize the condensate to cool the condenser 22 and improve the air conditioning energy efficiency.

[0035] Furthermore, the connecting pipe assembly 30 includes at least a return air hose and a water pump pipe (not shown in the figure). It can be understood that the connecting pipe assembly 30 is mainly used for the connection between the indoor unit 10 and the outdoor unit 20.

[0036] Furthermore, such as Figure 5 As shown, the indoor unit main bracket unit 42 includes two vertical brackets 421 that are perpendicularly connected to two U-shaped connecting brackets 432 respectively. An indoor unit bracket connecting rod is connected between the two vertical brackets 421. Support connecting rods 422 that are movably connected to the side walls of the two vertical brackets 421 at a preset inclination angle with the vertical brackets 421 are also respectively.

[0037] Specifically, the U-shaped connecting bracket 432, the vertical bracket 421, the indoor bracket connecting rod, and the support connecting rod 422 are mainly used for the indoor unit unit 10 to be installed on the indoor unit main bracket unit 42.

[0038] Furthermore, the indoor unit main support unit includes two vertical supports that are perpendicularly connected to the two U-shaped connecting frames, and an indoor unit support connecting rod is connected between the two vertical supports. The two U-shaped connecting frames, the two vertical supports, and the indoor unit support connecting rod are each provided with a number of welding points for welding and covering the indoor unit.

[0039] like Figure 6 As shown, in a preferred embodiment provided in this application, another installation method is also provided, namely, based on the U-shaped connecting bracket 432 and the vertical bracket 421, the two U-shaped connecting brackets 432, the two vertical brackets 421, and the indoor unit bracket connecting rod 423 are respectively provided with a number of welding points for welding and covering the indoor unit unit, thereby realizing that the indoor unit unit 10 is connected to the indoor unit main bracket unit 42, thereby avoiding the indoor unit unit 10 from obstructing the user's view.

[0040] Furthermore, the outdoor unit main support unit 41 includes two L-shaped supports 411 that are perpendicularly connected to the two U-shaped connecting frames 431 respectively. The two ends of the L-shaped supports are connected to outdoor unit support reinforcing rods 412, and the bottom of the two L-shaped supports is provided with a square frame 413 for supporting the outdoor unit unit.

[0041] Specifically, the outdoor unit unit 20 is supported by two L-shaped brackets 411, an outdoor unit bracket reinforcing rod 412, and a square frame 413.

[0042] Furthermore, the two L-shaped brackets 4111 are respectively provided with bolt fixing holes near the two U-shaped connecting brackets 431, for locking the outdoor unit unit by inserting the screw 414 into the bolt fixing holes.

[0043] Specifically, after the outdoor unit 20 is placed on the outdoor unit main bracket unit 42, it is also necessary to ensure the stability of the outdoor unit 20. This application uses a screw 414 to insert a bolt to hold the outdoor unit 20 in place, thereby locking the outdoor unit 20.

[0044] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
