Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, specifically to a fresh air cabinet air conditioner. Background Technology

[0002] With social development and the continuous improvement of people's living standards, air conditioners have become widely used. When users close doors and windows and use air conditioners, people spend a long time indoors, and the indoor air circulation becomes worse and worse.

[0003] To address this issue, some new air-conditioning units with fresh air intakes have emerged on the market. However, the fresh air outlets of existing floor-standing air conditioners are mostly located on the back of the unit. These units are often placed in corners of the living room, where fresh air simply doesn't reach those areas. Furthermore, placing the back of the air conditioner against a wall reduces fresh air efficiency, and prolonged exposure to direct airflow onto the wall can damage it. Some units have the fresh air outlet on the front, but this often results in a large opening on the front, affecting the overall aesthetics of the unit.

[0004] In summary, existing fresh air conditioning systems have the following problems:

[0005] 1. The fresh air outlet is located on the back of the air conditioner, resulting in poor fresh air effect and low fresh air efficiency at a distance;

[0006] 2. The fresh air outlet is located on the back of the air conditioner, and blowing air towards the wall can easily damage the wall.

[0007] 3. The fresh air outlet is located on the back of the air conditioner, which affects the overall aesthetics. Utility Model Content

[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fresh air cabinet air conditioner to solve the problems of poor fresh air effect at a distance, low fresh air efficiency, easy damage to indoor walls and impact on the overall aesthetics of the existing fresh air air conditioner.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: a fresh air cabinet air conditioner, comprising an air conditioner body and a fresh air assembly that cooperates with the air conditioner body. The air conditioner body has an air guide channel, and the front of the air conditioner body is provided with a front air outlet connected to the air guide channel. The exhaust port of the fresh air assembly is connected to the air guide channel near the front air outlet, and an air outlet damper is movably provided at the front air outlet, which is opened or closed by a damper movement mechanism. The fresh air assembly includes a fresh air fan that draws in fresh air from the outside and exhausts it from the exhaust port.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This fresh air cabinet air conditioner features a front air outlet located on the front of the unit. This outlet is equipped with an air damper that opens and closes via a mechanism, resulting in a more aesthetically pleasing design. When not in use, the air damper closes the front air outlet, preventing dust and other contaminants from entering the unit. When fresh air needs to be introduced, the fresh air fan quickly draws in outside air, which then enters the air duct through the exhaust vent and is finally discharged into the room through the front air outlet. This provides a long-distance fresh air delivery, high efficiency, and prevents damage to interior walls. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described in detail below through specific embodiments:

[0018] Existing floor-standing air conditioners typically have their fresh air outlets located on the back. Since these units are often placed in living room corners, fresh air often doesn't reach areas far from the unit. Furthermore, placing the back of the unit against a wall reduces fresh air efficiency and can damage the wall over time. Some units have the fresh air outlet on the front, but this often results in a large opening that detracts from the overall aesthetics. To address these issues, such as... Figure 1 , Figure 2 as well as Figure 3As shown in the figure, this utility model embodiment proposes a fresh air cabinet air conditioner, including an air conditioner body 1 and a fresh air component 2 that cooperates with the air conditioner body 1. The air conditioner body 1 has an air guide channel 3 inside, and the front air outlet of the air conditioner body 1 is provided with a front air outlet connected to the air guide channel 3. The exhaust port of the fresh air component 2 is connected to the air guide channel 3 near the front air outlet, and an air outlet damper 4 is movably provided at the front air outlet, which is driven to move and open or close by a damper movement mechanism 5. The fresh air component 2 includes a fresh air fan 21 that draws in fresh air from the outside and exhausts it from the exhaust port.

[0019] This fresh air cabinet air conditioner has its front air outlet located on the front of the air conditioner body 1. The front air outlet is equipped with an air outlet damper 4 that is driven to open or close by the damper movement mechanism 5. This makes the overall appearance more aesthetically pleasing. When not in use, the air outlet damper 4 closes the front air outlet, preventing dust and other particles from entering the air conditioner body 1 from the front air outlet. When fresh air needs to be introduced into the room, the fresh air fan 21 runs to quickly draw in the fresh air from the outside, which then enters the air guide channel 3 through the exhaust vent and is discharged into the room through the front air outlet. The fresh air delivery distance is long, the fresh air output efficiency is high, and it will not damage the interior walls.

[0020] To better understand this solution, the above-mentioned structural parts will be further optimized below.

[0021] like Figure 2 , Figure 3 as well as Figure 4 As shown, according to another embodiment of the present invention, the fresh air cabinet air conditioner includes a fresh air volute 22, a fresh air exhaust shell 23, a fresh air rear shell 24, and a fresh air inlet pipe 25. The fresh air volute 22 is disposed in the mounting cavity on the rear side of the air conditioner body 1, and the fresh air fan 21 is rotatably disposed inside the fresh air volute 22. The fresh air exhaust shell 23 is connected to the fresh air volute 22 and has an exhaust duct inside. One end of the exhaust duct is connected to the air outlet side of the fresh air volute 22, and the exhaust port is opened at the other end of the exhaust duct. The fresh air rear shell 24 is located on the air inlet side of the fresh air volute 22 and is connected to the rear side of the air conditioner body 1 to seal the mounting port of the mounting cavity. One end of the fresh air inlet pipe 25 is connected to the outside, and the other end is disposed on the fresh air rear shell 24 to connect to the air inlet side of the fresh air volute 22.

[0022] In this embodiment, the fresh air volute 22 is formed by the cooperation of a fresh air rear volute 221 and a fresh air front volute 222, so that the fresh air fan 21 can be installed inside the fresh air volute 22; one end of the fresh air inlet pipe 25 is installed outdoors. In use, the fresh air fan 21 is turned on to draw in fresh air from outdoors through the fresh air inlet pipe 25, and then the fresh air passes through the fresh air rear shell 24, the fresh air volute 22 and the exhaust duct in sequence, and then enters the air guide channel 3 from the exhaust port to be discharged into the room from the front air outlet.

[0023] To remove dust and other particles from the incoming fresh air, the fresh air assembly 2 also includes a fresh air filter 26, which is disposed inside the fresh air rear shell 24 and located on the air inlet side of the fresh air volute 22. After passing through the fresh air rear shell 24, the fresh air is filtered by the fresh air filter 26, then passes through the fresh air volute 22 and the exhaust duct, and finally enters the air guide channel 3 from the exhaust port to be discharged into the room from the front air outlet, ensuring that the incoming fresh air is relatively clean.

[0024] The fresh air filter 26 is a HEPA filter, which can filter out tiny particulate matter in the fresh air, such as dust, pollen, smoke, bacteria, and viruses, significantly improving the quality of the fresh air. At the same time, the fresh air filter 26 has an arc-shaped block structure, providing a larger filtration area and better filtration efficiency.

[0025] Furthermore, the fresh air assembly 2 also includes a fresh air intake bracket 27. The fresh air intake bracket 27 is disposed within the fresh air rear housing 24 and has a mounting position that abuts against the fresh air filter 26. The fresh air intake bracket 27 also has an air guide hole connecting the fresh air intake duct 25 and the air intake side of the fresh air filter 26. Here, the fresh air intake bracket 27, located within the fresh air rear housing 24 and cooperating with the fresh air filter 26, allows the fresh air filter 26 to be more stably arranged on the air intake side of the fresh air volute 22.

[0026] like Figure 3 and Figure 4 As shown, according to another embodiment of the present invention, in the fresh air cabinet air conditioner, a fresh air damper 29 is rotatably provided inside the exhaust port of the fresh air component 2, which is driven to rotate by a driver 28 to open or close.

[0027] In this embodiment, the driver 28 is a motor and is installed on the outer wall of the fresh air rear volute 221. The driver 28 drives the fresh air damper 29 to rotate via a shaft, thereby opening or closing the exhaust vent. Specifically, when fresh air is needed, the driver 28 drives the fresh air damper 29 to rotate via a shaft, thereby opening the exhaust vent. Then, the fresh air fan 21 starts to draw in outdoor fresh air from the fresh air inlet duct 25. The fresh air then passes through the fresh air rear casing 24, the fresh air filter 26, the fresh air volute 22, and the exhaust duct in sequence, and then enters the air guide channel 3 from the exhaust vent to be discharged into the room from the front air outlet. When fresh air is no longer needed, the fresh air fan 21 is turned off, and at the same time, the driver 28 drives the fresh air damper 29 to rotate in the opposite direction via a shaft, thereby closing the exhaust vent.

[0028] like Figure 3 As shown, according to another embodiment of the present invention, the air conditioner body 1 has a top air outlet 6 that communicates with the air guide channel 3.

[0029] In this embodiment, the fresh air cabinet air conditioner has two air outlets: a front air outlet, which is specifically located on the bottom side of the front of the air conditioner body 1, and a top air outlet 6. The combination of the front air outlet and the top air outlet 6 enables the fresh air cabinet air conditioner to have a larger air distribution range.

[0030] The top air outlet 6 is equipped with a louver mechanism 7 for adjusting the airflow direction. In this embodiment, the louver mechanism 7 is an existing structure, such as including multiple louvers that rotate and cooperate within the top air outlet 6 and an adjustment component connected to the multiple louvers; the adjustment component drives the multiple louvers to rotate synchronously, thereby adjusting the airflow direction of the top air outlet 6 to the desired direction.

[0031] like Figure 3 and Figure 4 As shown, according to another embodiment of the present invention, in the fresh air cabinet air conditioner, two centrifugal fans 8 are arranged at intervals along the vertical direction in the air guide channel 3.

[0032] Specifically, two centrifugal fans 8 operate, drawing air in through the air inlet 9 at the rear of the air conditioner unit 1. After heat exchange in the evaporator 10, the air enters the air guide duct 3, and is then guided through the air guide duct 3 to the front air outlet and top air outlet 6 for discharge into the room, thus exchanging heat with the indoor air. The use of two centrifugal fans 8 in conjunction increases airflow efficiency, allowing this fresh air cabinet air conditioner to deliver air over a longer distance.

[0033] In this embodiment, the air guide channel 3 is formed between the rear air duct plate 11 and the rear front air duct plate 12 of the air conditioner. A fresh air inlet 9 is opened on the bottom side of the rear air duct plate 11 to connect the exhaust port with the air guide channel 3.

[0034] like Figure 3 As shown, according to another embodiment of the present invention, the air conditioning unit 5 of the fresh air cabinet air conditioner includes a gear, a motor for driving the gear to rotate, a rack meshing with the gear, and at least one transmission bar rotatably connected between the rack and the air outlet damper 4, wherein the rack slides vertically within the air conditioning body 1.

[0035] When in use, the motor runs, driving the gear to rotate. The gear drives the rack to move, and the moving rack moves the air outlet damper 4 into the air conditioner body 1 through the transmission bar to open the front air outlet; or the motor runs in the opposite direction to move the air outlet damper 4 in the opposite direction to the front air outlet to close the front air outlet.

[0036] In this embodiment, the damper movement mechanism 5 can also be other existing structures, which will not be further described here.

[0037] When this fresh air cabinet air conditioner is used to exchange heat indoors:

[0038] With the exhaust vent closed and the front air outlet open, the two centrifugal fans 8 are running. Air is drawn in from the air inlet 9 at the rear of the air conditioner body 1, and after heat exchange through the evaporator 10, it enters the air guide duct 3. The heat-exchanged air is then guided through the air guide duct 3 to the front air outlet and the top air outlet 6 to be discharged into the room for heat exchange.

[0039] When using this fresh air cabinet air conditioner:

[0040] With the exhaust vent and the front air outlet open, the fresh air fan 21 starts to draw in fresh outdoor air from the fresh air inlet duct 25. The fresh air then passes through the fresh air rear shell 24, the fresh air filter 26, the fresh air volute 22, and the exhaust duct in sequence, and then enters the air guide channel 3 from the exhaust vent to be discharged into the room from the front air outlet.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
