[0035] In addition, the terms "first" and "second" mentioned in the embodiments of the present invention are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0036] Combination Figures 1 to 10 As shown, this embodiment provides an air-conditioning cabinet, including a shell, the shell including a chassis and a first shell part 1 and a second shell part 2 arranged on the chassis, and the first shell part 1 is arranged on the front side of the second shell part 2. Independent air duct structures are formed inside the first shell part 1 and the second shell part 2, and the first shell part 1 and the second shell part 2 are interconnected, and the air between the two can circulate with each other. In this embodiment, the first shell part 1 and the second shell part 2 are both cylindrical, and the cylindrical shell of the second shell part 2 is connected to the cylindrical shell of the first shell part 1. In other embodiments, the first shell part 1 and the second shell can be other geometric shapes such as a rectangular parallelepiped. The second shell part 2 needs to be higher than the first shell part 1, so that the air outlets of the two can be set at different heights.

[0037] The air conditioner cabinet has an air inlet 3 and two air outlets, the two air outlets are the first air outlet 4 and the second air outlet 5. The air inlet 3 is arranged at the rear side of the second housing part 2, and is used to absorb air from the external space. The first air outlet 4 is arranged at the front side of the first housing part 1, and the second air outlet 5 is arranged at the top of the second housing part 2. The position of the second air outlet 5 is higher than the air inlet 3 and the first air outlet 4. The air entering from the air inlet 3 becomes cold air or hot air under the action of the cooling / heating system. Since the first housing part 1 and the second housing part 2 are interconnected, the cold air or hot air can be blown forward from the first air outlet 4, or blown upward from the second air outlet 5. In other embodiments, the second air outlet 5 can also be arranged at the upper part of the second housing part 2, and its position still needs to be higher than the first air outlet 4, and the air outlet direction of the second air outlet 5 needs to avoid the first housing part 1 to avoid the air outlet being blocked.

[0038] The first housing portion 1 is provided with a first fan 6. When the first fan 6 is started, the wind will blow forward from the first air outlet 4. The second housing portion 2 is provided with a second fan 7. When the second fan 7 is started, the wind will blow upward from the second air outlet 5. The air conditioner cabinet has two sets of independent air outlet structures. The first air outlet 4 and the first fan 6 can make the air conditioner blow air to the front side, and the second air outlet 5 and the second fan 7 can make the air conditioner blow air upward. In this way, the air conditioner can realize multiple air outlet modes by switching the operating status of the two fans and the opening and closing status of the air outlet. The most suitable air outlet mode can be selected according to cooling, heating or other needs of the user to improve the comfort of the air conditioner.

[0039] Combination Figure 6 , Figure 8 and Fig.10 As shown, the first fan 6 arranged in the first housing portion 1 is a cross-flow fan, and the first fan 6 is installed vertically, that is, installed along the Y-axis direction in the figure. The cross-flow fan can blow the airflow sucked in by the rear air inlet 3 out of the front first air outlet 4. The axial length of the cross-flow fan can be set according to the extension length of the first air outlet 4, and the air outlet is uniform, and the airflow blown out can reach a long distance, so that the temperature in the environment is balanced. A sweeping blade 9 is provided in the first air outlet 4, and the sweeping blade 9 can rotate up and down and left and right to adjust the air outlet direction from the first air outlet 4.

[0040] Combination Figure 7 , Fig. 9 and Fig.10 As shown, the second fan 7 arranged in the second housing portion 2 is a centrifugal fan, and the second fan 7 is horizontally arranged at the upper part of the second housing portion 2, that is, installed along the X-axis direction in the figure. Its fixed position is higher than the air inlet 3 and close to the second air outlet 5. The centrifugal fan can blow the airflow sucked in by the lower air inlet 3 out from the upper second air outlet 5 and flow to the upper part of the air conditioner. The centrifugal fan has a large air output, stable operation, low noise and small vibration.

[0041] The two air outlets of the air conditioner cabinet can be opened together, and the first fan 6 and the second fan 7 can be started at the same time, which can effectively expand the air supply area of ​​the air conditioner, increase the air volume, make the indoor environment temperature faster and more uniform, and improve human comfort.

[0042] The first air outlet 4 covers a large area in the first housing portion 1 and is an arc-shaped long plate surface, and the distance between the lower end and the bottom of the housing is 30 cm. In other embodiments, the distance between the lower end of the first air outlet 4 and the bottom of the housing is controlled to be 20 cm-40 cm, so that the lower end of the first air outlet 4 is lower from the ground, and the wind blown out from the first air outlet 4 can be closer to the ground. In this way, when the air conditioner is in the heating state, the hot air will move from the bottom to the top, so that the temperature in the space is balanced and a large deviation in the upper and lower temperatures in the environment is avoided.

[0043] In this embodiment, the extension height between the upper end and the lower end of the first air outlet 4 is 90 cm, which ensures that the air outlet has a larger area and can increase the air outlet coverage area. In other embodiments, the distance between the upper end and the lower end of the first air outlet 4 needs to be greater than or equal to 80 cm to ensure the air outlet area and air volume.

[0044] In this embodiment, the height of the second housing portion 2 is 200 cm, the top surface of the second housing portion 2 is inclined, the second air outlet 5 is arranged at the top of the second housing portion 2, and the wind blown out from the second air outlet 5 flows obliquely upward. In other embodiments, the height of the second housing portion 2 is 170 cm-200 cm, and the height of the second air outlet 5 is controlled so that the distance between the lower end of the second air outlet 5 and the bottom of the housing is 180 cm-200 cm. When the second fan 7 is working, the wind blown out from the second air outlet 5 flows obliquely upward, and the height of the second air outlet 5 exceeds the average human height, so that the wind blown out from the second air outlet 5 will not blow directly on the human body, and the comfort and safety of the air conditioner are high.

[0045] In this embodiment, a control panel for controlling the operation state of the air conditioner is provided on the top of the first housing portion 1. For ease of control, the height of the first housing portion 1 is 120 cm. In other embodiments, the height of the first housing portion 1 is between 100 cm and 130 cm to meet ergonomics. The height of the first housing portion 1 is lower than the height of the second air outlet 5, so that the first housing portion 1 will not block the wind blown out of the second air outlet 5.

[0046] Combination Figures 1 to 3As shown, the air conditioning cabinet of this embodiment has two sets of relatively independent air outlet structures. In order to enable the two sets of air outlet structures to operate independently, the first air outlet 4 and the second air outlet 5 can be switched between closed and open states. A movable air guide door 8 is provided on the front side of the first shell portion 1. The air guide door 8 includes two left and right door panels, and the door panels on both sides can move in opposite directions. When the left and right door panels are opened, they move to both sides and away from each other, exposing the first air outlet 4. When the left and right door panels are closed, they approach and fit each other, so that the first air outlet 4 is closed, and the air in the shell cannot be blown forward from the first air outlet 4, so as to prevent the air conditioner from blowing directly on the human body.

[0047] Combination Figure 4 As shown, in this embodiment, a plurality of rotatable air guide plates 10 are provided on the second air outlet 5, and the second air outlet 5 can be opened and closed by rotating the air guide plates 10, and the air guide plates 10 can also change the gas flow direction of the second air outlet 5. In the heating mode of the air conditioner, the second fan 7 is turned off, the air guide plates 10 close the second air outlet 5, the first fan 6 is working, and the cross-flow fan blows hot air out of the first air outlet 4. Since the first is cylindrical, the part covered by the first air outlet 4 is an arc-shaped surface, thereby realizing wide-angle heating.

[0048] Combination Figure 7 As shown, a rotating housing portion 11 is provided on the top of the second housing portion 2. The rotating housing portion is arranged at the position of the second air outlet 5. The rotating housing portion can rotate relative to other parts of the second housing portion 2. When the rotating housing portion rotates, the position and angle of the second air outlet 5 change. When the second fan 7 is started, the rotating housing portion 11 rotates relative to the second housing portion 2 with the front side of the second housing portion 2 as a fulcrum, fixes the second air outlet 5 to a preset tilt angle, and the air guide plate 10 rotates open to allow air flow to flow out of the second air outlet 5. The angle between the second air outlet 5 and the bottom surface of the outer shell is defined as the second air outlet angle α. The rotation of the rotating housing portion 11 can fix the second air outlet angle α at any angle between 5° and 45°, that is, the rotating housing portion 11 can control the air outlet angle of the second air outlet 5 according to the program setting.

[0049] During cooling, the cold air flows out from the second air outlet 5, and the rotating shell part 11 fixes the second air outlet 5 in an inclined position. The gas flows obliquely upward of the air conditioner. Since the density of the cold air is relatively large, the wind blown upward will naturally sink into the lower space of the environment, thus achieving a waterfall-like cooling effect, allowing the ambient temperature to quickly reach a balanced state, thereby improving human comfort and enhancing user experience.

[0050] Another embodiment of the present invention provides an air conditioning cabinet, including a shell, the shell including a first shell part 1 and a second shell part 2, the first shell part 1 and the second shell part 2 are not connected to each other, and the first shell part 1 is arranged on the left or right side of the second shell part 2. The air conditioning cabinet has two air inlets 3 and two air outlets, the two air inlets 3 are respectively arranged on the rear sides of the first shell part 1 and the second shell part 2, and the two air outlets are respectively a first air outlet 4 and a second air outlet 5, the first air outlet 4 is arranged on the front side of the first shell part 1, and the second air outlet 5 is arranged on the top of the second shell part 2, and the position of the second air outlet 5 is higher than the first air outlet 4. A first fan 6 is arranged in the first shell part 1, and when the first fan 6 is started, the wind will blow forward from the first air outlet 4. A second fan 7 is arranged in the second shell part 2, and when the second fan 7 is started, the wind will blow upward from the second air outlet 5. The first fan 6 arranged in the first shell part 1 is a cross-flow fan, and the second fan 7 arranged in the second shell part 2 is a centrifugal fan. The two air outlets of the air conditioner cabinet can be opened together, and the first fan 6 and the second fan 7 can be started and operated at the same time, which can effectively expand the air supply area of ​​the air conditioner, increase the air output, make the indoor environment temperature faster and more uniform, and improve human comfort.

[0051] The air conditioning cabinet provided in the above embodiment can realize multiple air outlet modes. After the user selects the operating mode of the air conditioner, the air conditioning cabinet will automatically switch to the corresponding air outlet mode to ensure the user's comfort to the greatest extent.

[0052] When the air conditioner is in cooling mode, the air guide door 8 and the air guide plate 10 of the air conditioner cabinet are both opened, so that the first air outlet 4 and the second air outlet 5 are in an open state, and the rotating shell part 11 is rotated to a suitable angle to control the first fan 6 and the second fan 7 to be in a start-up state. External air enters the shell from the air inlet 3, and after being cooled by the cooling system, the first fan 6 blows part of the cold air from the first air outlet 4 to the front side of the air conditioner, and the second fan 7 blows the other part of the cold air from the second air outlet 5 to the top of the air conditioner. The two air outlets blow air at the same time, and the air conditioner has a large air supply area and can quickly make the temperature in the environment reach a balanced state.

[0053] When the user is close to the air conditioner, the user may be blown by the direct wind from the first air outlet 4, causing discomfort to the human body. The air conditioner can be switched to the avoid-people mode. In this mode, the air guide door 8 is closed, so that the first air outlet 4 is in a closed state, and the first fan 6 is controlled to stop at the same time, so that no wind blows out of the first air outlet 4. The rotating shell part 11 is rotated to a suitable angle, the air guide plate 10 is rotated to open the second air outlet 5, and the second fan 7 is controlled to be in the starting state. The second fan 7 blows the cold air out of the second air outlet 5 obliquely upward, realizing waterfall-style cooling, with good cooling effect and high comfort.

[0054] When the air conditioner is switched to the heating mode, the rotating housing part 11 is retracted, the air guide plate 10 is rotated and closed, so that the second air outlet 5 is in a closed state, and the second fan 7 stops running. The air guide door 8 moves to open the first air outlet 4, and the first fan 6 is started. The external air enters the housing from the air inlet 3, and after being heated by the heating system, the first fan 6 blows the hot air out from the first air outlet 4 to the front side of the air conditioner to achieve wide-angle heating. The air sweeping blades in the first air outlet 4 can rotate to change the air outlet direction and adjust to a suitable air outlet angle.

[0055] Compared with the traditional single-fan air conditioner with only one air outlet mode, the air conditioner cabinet provided in the embodiment of the present invention has a plurality of optional air outlet modes, and the user can switch according to the use needs. The first fan 6 of the air conditioner cabinet is a cross-flow fan, which increases the left and right cooling / heating areas, allows the use scene to reach a uniform temperature faster, and improves the comfort of the air conditioner. In the mode of avoiding direct wind blowing on people, the air conditioner cabinet closes the first air outlet 4, and the second fan 7 allows the wind to blow upwards from the second air outlet 5 on the rotating shell part 11, thereby improving the safety of the air conditioner, meeting the user's use needs in multiple scenarios, and improving the user experience.

[0056] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
