[0033] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the embodiments of the present invention.

[0034] The indoor unit of an air conditioner is a crucial component and is typically mounted on an outdoor wall. To ensure free air flow in and out of the outdoor unit, a certain distance must be maintained between the outdoor unit and the wall, allowing air to enter through the air inlet on the back of the unit. However, this approach prevents the outdoor unit from being placed close to the wall, thus occupying a significant amount of installation space.

[0035] In view of this, an embodiment of the present invention provides an air-conditioning outdoor unit and an air conditioner, in which the air inlet and the air outlet are arranged on the first panel of the outer unit casing, that is, the air inlet and the air outlet are integrated on the same side of the outer unit casing. When the outer unit casing is installed, it can be close to the outdoor wall or other installation surface, thereby reducing the installation distance between the outer unit casing and the outdoor wall, effectively reducing the space occupied by the outer unit casing during installation, and improving the installation flexibility of the outer unit casing.

[0036] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.

[0037] like Figure 1 and Figure 2 As shown, the embodiment of the present invention provides an air-conditioning outdoor unit, which includes:

[0038] The outdoor air duct 200 is used to define the flow direction of air inside the outdoor unit of the air conditioner; and

[0039] The external unit housing 100 includes a first panel, which is provided with an air inlet 110 and an air outlet 120. The external unit air duct 200 is provided inside the external unit housing 100 and connects the air inlet 110 and the air outlet 120. It is understood that the external unit housing 100 includes at least the first panel, and the air inlet 110 and the air outlet 120 are arranged side by side on the first panel. The air inlet 110 and the air outlet 120 can be arranged side by side vertically or side by side horizontally, without limitation. In this way, the air inlet 110 and the air outlet 120 are integrated on the same side of the external unit housing 100, and air can flow into or out of the external unit air duct 200 on the same side of the external unit housing 100. When installing the external machine casing 100, the back of the external machine casing 100 can be close to the outdoor wall or other installation surface, and there is no need to reserve air flow space, thereby reducing the installation distance between the external machine casing 100 and the outdoor wall, and further reducing the installation space occupied by the external machine casing 100. As an optional method, the air inlet 110 and the air outlet 120 can both be long holes with a larger ventilation area, which can improve the ventilation effect. Of course, in other embodiments, the air inlet 110 and the air outlet 120 can also be circular holes, irregular holes, etc., which will not be described in detail. Specifically, the material of the external machine casing 100 can be metal, which has a greater structural strength and can effectively improve the service life. In other embodiments, the surface of the external machine casing 100 can also be sprayed with an anti-corrosion coating or the entire surface can be made of corrosion-resistant stainless steel to reduce the corrosion of the external machine casing 100 by rainwater.

[0040] In the technical solution adopted in this embodiment, the air inlet 110 and the air outlet 120 are arranged on the first panel of the external housing 100. In other words, the air inlet 110 and the air outlet 120 are integrated on the same side of the external housing 100, so that air can enter and exit from the same side of the external housing 100. In this way, when the external housing 100 is installed, it can be closely attached to the outdoor wall or other installation surface, and there is no need to reserve air inlet or air outlet space between the back of the external housing 100 and the outdoor wall. This reduces the installation distance between the external housing 100 and the outdoor wall, effectively reducing the space occupied by the external housing 100 during installation and improving the installation flexibility of the external housing 100.

[0041] In one embodiment of the present invention, the first panel is the front panel of the external unit housing 100. For conventional air conditioner external units, air typically enters from the front. Therefore, in this embodiment, the first panel is the front panel, and the air inlet 110 and the air outlet 120 are provided on the front panel. This allows air to enter the external unit air duct 200 from the front side of the external unit housing 100 and to flow out of the external unit air duct 200 from the front side of the external unit housing 100. The rear side of the external unit housing 100 can be in close contact with an outdoor wall or other mounting surface.

[0042] Alternatively, the air inlet 110 may be located below the air outlet 120. Conventional air conditioners are typically primarily cooling, while the outdoor unit primarily releases heat. This means that the air outlet 120 of the outdoor unit housing 100 blows out hot air, which is lighter and tends to float upward. Placing the air inlet 110 below the air outlet 120 prevents the hot air from being reabsorbed by the air inlet 110, thereby improving heat exchange efficiency.

[0043] In one embodiment of the present invention, referring to Figure 2 The external unit air duct 200 is provided with a volute 210 , and a cross-flow impeller 220 is provided in the volute 210 . The cross-flow impeller 220 is horizontally installed on the volute 210 .

[0044] Specifically, the cross-flow impeller 220 can accelerate the flow of air from the air inlet 110 toward the air outlet 120, and the circulation of air is accelerated, which is beneficial to improving the cooling and heating effects. It can be understood that the cross-flow impeller 220 rotates at a high speed in the outer casing 100, attracting air to flow in from the air inlet 110 and out from the air outlet 120. In one embodiment, the cross-flow impeller 220 is installed horizontally, which reduces the height of the outer casing 100 compared to the vertical installation, and can facilitate installation in some shorter installation spaces. The main function of the volute 210 is to guide the airflow so that the airflow flows in the designed direction and speed, that is, from the air inlet 110 to the air outlet 120.

[0045] In one embodiment of the present invention, referring to Figure 2 The air conditioner outdoor unit also includes an outdoor heat exchanger 300, which is located between the crossflow impeller 220 and the air inlet 110. Heat absorbed by the indoor air is transferred to the outdoor air through the outdoor heat exchanger 300, allowing the air conditioning system to continue operating. Alternatively, the outdoor heat exchanger 300 can be configured as a condenser.

[0046] In one embodiment of the present invention, the air inlet area of the air inlet 110 is larger than the air outlet area of the air outlet 120. This allows for greater air volume and ensures efficient air flow. In one embodiment, the diameter of the air inlet 110 is larger than the diameter of the air outlet 120; in other embodiments, the number of air inlets 110 is greater than the number of air outlets 120. All of the above methods can achieve a larger air inlet area for the air inlet 110 than the air outlet area for the air outlet 120. In actual applications, the preferred method can be selected and used without limitation.

[0047] In one embodiment of the present invention, referring to Figure 2 The outdoor heat exchanger 300 includes a first heat exchange section 310 and a second heat exchange section 320 connected to the lower end of the first heat exchange section 310. The first heat exchange section 310 extends vertically, while the second heat exchange section 320 extends downward and tilted inward from the air inlet 110. This tilted second heat exchange section 320 helps distribute airflow more evenly across the surface of the first heat exchange section 310, reducing wind resistance upon entry and noise generated by the collision of airflow with the first heat exchange section 310, thereby enhancing the user experience.

[0048] In one embodiment of the present invention, referring to Figure 3 and Figure 4 The outer housing 100 is provided with an installation opening 130, which extends through the outer housing 100. The installation opening 130 is provided with a pipe insertion structure 400, which has a pipe insertion passage 430. The pipe insertion structure 400 is rotatably connected to the outer housing 100, allowing the direction of the pipe insertion passage 430 to be adjusted. Thus, by rotating the pipe insertion structure 400, the pipe insertion passage 430 can be directed toward an outdoor wall or the ground. In other words, by rotating the pipe insertion structure 400, pipe insertion can be achieved in either a horizontal or vertical direction, thereby meeting different installation requirements.

[0049] In one embodiment of the present invention, referring to Figure 5 The pipe-penetrating structure 400 includes:

[0050] A baffle 410 is provided at the mounting opening 130; and

[0051] The side plates 420 are respectively provided at opposite ends of the baffle 410 . The baffle 410 and the two side plates 420 form a pipe passage 430 . The side plates 420 are rotatably connected to the outer casing 100 .

[0052] Specifically, the pipe-through structure 400 includes a baffle 410 and side panels 420. A side panel 420 is provided at each end of the baffle 410. The two side panels 420 are spaced apart along the length of the external housing 100 and are rotatably connected to the external housing 100 via a rotating shaft. Thus, the baffle 410 and the two side panels 420 form a pipe-through passage 430. The pipe-through passage 430 has at least two openings, one of which communicates with the interior of the external housing 100 and the other with the exterior of the external housing 100. This allows refrigerant pipes or other pipelines to be inserted into the interior of the external housing 100 along the pipe-through passage 430. To prevent the side panels 420 from rotating freely, the rotating shaft is configured as a damping shaft, capable of hovering at a predetermined position.

[0053] In one embodiment of the present invention, referring to Figure 5 The side panel 420 has a first side edge 421, a second side edge 422, and a third side edge 423. The first side edge 421 is connected to the baffle 410, the second side edge 422 is adjacent to the first side edge 421, and the third side edge 423 connects the free ends of the first side edge 421 and the second side edge 422. The third side edge 423 is arranged in an arc shape. In this way, the arc-shaped third side edge 423 can prevent the side panel 420 from colliding with the inner wall of the installation opening 130 during rotation, thereby improving the smoothness of the rotation of the side panel 420.

[0054] To achieve the above objectives, the present invention provides an air conditioner comprising the outdoor unit described above and an indoor unit connected to the outdoor unit. The outdoor unit has a structure similar to that of the aforementioned embodiment. Since the present air conditioner utilizes all of the technical solutions of the aforementioned embodiment, it possesses at least all of the beneficial effects of the technical solutions of the aforementioned embodiment, and therefore, no further details will be given here.

[0055] It should be noted that the air conditioner of the present invention can be a split-type air conditioner that is easy for users to install individually. It uses a refrigerant pipe to connect the indoor heat exchanger and the outdoor heat exchanger 300, and refrigerant is injected into the refrigerant circuit before the device leaves the factory. In this way, when users install the device themselves, they only need to fix the indoor and outdoor units of the air conditioner separately, without having to assemble the refrigerant pipe and add refrigerant, thereby reducing the installation difficulty and enabling user-friendly installation. However, the present design is not limited to this. In other embodiments, the air conditioner of the present invention can also be a conventional split-type air conditioner.

[0056] In one embodiment of the present invention, the air conditioner outdoor unit is connected to the air conditioner indoor unit via a refrigerant hose. In this way, the refrigerant hose can be bent to facilitate the movement of the air conditioner indoor unit.

[0057] And / or, the bottom surface of the air conditioner indoor unit is provided with rolling wheels, so that the user can move the air conditioner indoor unit to a suitable position according to the indoor environment or personal preference, saving time and effort. In one embodiment, at least three rolling wheels are provided to improve the stability of the moving process.

[0058] And / or, the compressor of the air conditioner is arranged in the indoor unit of the air conditioner. That is to say, the compressor is arranged indoors, that is, integrated in the indoor unit of the air conditioner, which can reduce the weight of the outdoor unit of the air conditioner, thereby facilitating the installation of the outdoor unit of the air conditioner. At the same time, since the outdoor unit of the air conditioner usually needs to be fixed on a bracket, the reduction in the weight of the outdoor unit of the air conditioner can reduce the pressure on the bracket, prevent the bracket from being subjected to excessive pressure and causing the risk of cracking, thereby increasing the service life of the bracket. In addition, since the compressor will generate noise or vibration when working, a vibration-damping structure, such as rubber, plastic, etc., can be provided at the bottom of the compressor to absorb vibration. A soundproof cover can also be provided on the outside of the compressor to absorb or reduce noise, making the indoor environment relatively quiet, reducing the impact of noise on users, and providing users with a comfortable rest environment.

[0059] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the embodiments of the present invention. All equivalent structural transformations made using the description and drawings of the embodiments of the present invention under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the embodiments of the present invention.
