Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to an indoor air conditioner unit with four-way air outlet. Background Technology

[0002] A wall-mounted air conditioner indoor unit is a type of air conditioner indoor unit that is suspended on a wall. It has an air inlet at the top and an air outlet at the lower front. An air guide plate is installed at the air outlet. A heat exchanger and a cross-flow fan are installed in the air duct between the air inlet and outlet. During operation, air enters the air duct from the air inlet under the action of the cross-flow fan, undergoes heat exchange in the heat exchanger, and is blown out from the air outlet. The angle of the air guide plate can be adjusted to direct the airflow forward or downward. However, when only one air outlet is used, adjusting the air outlet angle by rotating the air guide plate results in a smaller air delivery range and volume, thus affecting the air delivery efficiency of the indoor unit.

[0048] Figure 1 This is a schematic structural diagram of an indoor air conditioning unit according to an embodiment of the present invention. The arrows in the diagram indicate the direction of airflow. Figure 1 As shown, and refer to Figures 2 to 7 This utility model provides an indoor air conditioning unit 100 with four-way air outlets, including a housing 10 and an axial flow fan 40. The housing 10 defines an air outlet cavity 130. A first air outlet 210 penetrating the housing 10 is provided on the left cavity wall of the air outlet cavity 130, and a second air outlet 220 penetrating the housing 10 is provided on the right cavity wall of the air outlet cavity 130. The axis of the axial flow fan 40 is horizontally arranged, and the axial flow fan 40 is located on the rear side of the air outlet cavity 130.

[0049] In this embodiment, the indoor unit 100 of the air conditioner has an air outlet cavity 130 inside. An axial flow fan 40 for supplying air to the front is located on the rear side of the air outlet cavity 130. A first air outlet 210 is located on the left wall of the air outlet cavity 130, and a second air outlet 220 is located on the right wall of the air outlet cavity 130. When the indoor unit 100 of the air conditioner is running, the axial flow fan 40 supplies air to the air outlet cavity 130. After the airflow enters the air outlet cavity 130, it diffuses within the air outlet cavity 130 and is finally discharged from the first air outlet 210 on the left and the second air outlet 220 on the right. Compared to airflow from a single air outlet, airflow from both air outlets simultaneously increases the air volume of the indoor unit 100 of the air conditioner, thereby improving the airflow effect of the indoor unit 100 and enhancing the user experience. Furthermore, the first air outlet 210 blows air to the left and the second air outlet 220 blows air to the right, increasing the air supply range of the indoor unit 100, making the indoor temperature distribution more uniform, thereby improving the comfort of the human body and enhancing the user experience.

[0050] Furthermore, by supplying air to the outside via the axial flow fan 40, compared to a cross-flow fan, the axial flow fan 40 can provide a larger air volume during operation, further increasing the air volume output of the indoor unit 100. In addition, the axial flow fan 40 is characterized by low noise, maintaining a lower noise level during operation, making it more suitable for indoor environments and enhancing the user experience.

[0051] In some other embodiments of this utility model, multiple axial flow fans 40 are provided, and the multiple axial flow fans 40 are arranged horizontally.

[0052] In this embodiment, the indoor unit 100 of the air conditioner is provided with a plurality of axial flow fans 40, which blow air forward to increase the air volume of the indoor unit 100, thereby improving the air output effect of the indoor unit 100.

[0053] Furthermore, such as Figure 7 As shown, there are two axial flow fans 40.

[0054] In some embodiments of this utility model, such as Figures 2 to 4 As shown, the indoor unit 100 of the air conditioner also includes a heat exchanger 50, which is disposed within the air outlet cavity 130 and extends in the left-right direction. The rear edge of the first air outlet 210 is directly to the left of the left edge of the front surface of the heat exchanger 50. The rear edge of the second air outlet 220 is directly to the right of the right edge of the front surface of the heat exchanger 50.

[0055] In this embodiment, the axial fan 40 is located behind the heat exchanger 50. The airflow passes through the axial fan 40 before entering the heat exchanger 50 for heat exchange. The axial fan 40 has a small cross-sectional area, so when setting the air inlet 90, the air inlet area of ​​the air inlet 90 can be made as large as possible, thereby increasing the air intake volume of the indoor unit 100 and thus increasing the air output volume of the indoor unit 100.

[0056] Furthermore, the rear edges of the first air outlet 210 and the second air outlet 220 are located on the plane of the front surface of the heat exchanger 50. That is, after the airflow passes through the heat exchanger 50, it is blown out from the first air outlet 210 and the second air outlet 220, which shortens the flow path of the airflow after heat exchange, thereby reducing the energy loss of the airflow and improving the air outlet effect of the indoor unit 100 of the air conditioner, thus saving costs.

[0057] In some embodiments of this utility model, such as Figure 1 As shown, the indoor unit 100 of the air conditioner also includes a first air guide plate 310 and a second air guide plate 320. The first air guide plate 310 is rotatably disposed at the first air outlet 210, and the rotation axis of the first air guide plate 310 is disposed near the rear edge of the first air outlet 210. The second air guide plate 320 is rotatably disposed at the second air outlet 220, and the rotation axis of the second air guide plate 320 is disposed near the rear edge of the second air outlet 220.

[0058] In this embodiment, a first air guide plate 310 is rotatably disposed at the first air outlet 210, and a second air guide plate 320 is rotatably disposed at the second air outlet 220. When air is discharged from the first air outlet 210, the first air guide plate 310 opens the first air outlet 210, and the inner surface of the first air guide plate 310 guides the airflow blown out from the first air outlet 210. When air is discharged from the second air outlet 220, the second air guide plate 320 opens the second air outlet 220, and the inner surface of the second air guide plate 320 guides the airflow blown out from the second air outlet 220. The first air outlet 210 and the second air outlet 220 can discharge air simultaneously, thereby increasing the air volume and air range of the air conditioner indoor unit 100. The rotation angles of the first air guide plate 310 and the second air guide plate 320 can be the same or different, that is, the air delivery angle and air volume of the first air outlet 210 and the second air outlet 220 can be the same or different. The first air outlet 210 and the second air outlet 220 can also output air independently. When outputting air independently, the air output speed of the indoor unit 100 of the air conditioner is increased.

[0059] By setting the first air guide plate 310 and the second air guide plate 320, the air volume, air angle and air speed of the first air outlet 210 and the second air outlet 220 are adjusted, thereby adjusting the air volume and air supply range of the air conditioner indoor unit 100, so that the air conditioner indoor unit 100 has multiple air supply modes, improving the air supply effect of the air conditioner indoor unit 100, thereby meeting the different air blowing needs of users and improving the user experience.

[0060] In some embodiments of this utility model, the first air guide plate 310 is provided with micro-holes 60, and the second air guide plate 320 is provided with micro-holes 60, so that when the first air outlet 210 and the second air outlet 220 are in the closed state, the airflow flows out from the micro-holes 60.

[0061] In this embodiment, both the first air guide plate 310 and the second air guide plate 320 are provided with micro-holes 60. When the first air outlet 210 and the second air outlet 220 are closed, airflow is blown out from the micro-holes 60 of the first air guide plate 310 and the second air guide plate 320. After passing through the micro-holes 60, the airflow is more uniform, further improving the uniformity of the airflow from the indoor unit 100. Furthermore, the airflow is dispersed by the micro-holes 60, making the airflow gentler and achieving a windless air delivery effect from the indoor unit 100, further enhancing the user experience.

[0062] In some embodiments of this utility model, such as Figure 2 As shown, a third air outlet 230 penetrating the housing 10 is provided on the upper cavity wall of the air outlet cavity 130, and a fourth air outlet 240 penetrating the housing 10 is provided on the lower cavity wall of the air outlet cavity 130.

[0063] In this embodiment, the indoor unit 100 of the air conditioner also includes a third air outlet 230 on the upper side and a fourth air outlet 240 on the lower side. The third air outlet 230 discharges air upwards, and the fourth air outlet 240 discharges air downwards. When the indoor unit 100 of the air conditioner is running, the axial flow fan 40 delivers air to the air outlet cavity 130. After the airflow enters the air outlet cavity 130, it diffuses within the air outlet cavity 130 and finally delivers air into the room from all four sides of the indoor unit 100. The air volume of the indoor unit 100 is relatively large, thereby improving the air delivery effect of the indoor unit 100 and enhancing the user experience. Moreover, the indoor unit 100 can discharge air from the upper, lower, left, and right sides, increasing the air delivery range of the indoor unit 100 and making the indoor temperature distribution more uniform, thereby improving the comfort of the human body and enhancing the user experience.

[0064] In some embodiments of this utility model, such as Figure 2 As shown, the indoor unit 100 of the air conditioner also includes a third air guide plate 330 and a fourth air guide plate 340. The third air guide plate 330 is rotatably disposed at the third air outlet 230, and the rotation axis of the third air guide plate 330 is disposed near the rear edge of the third air outlet 230. The fourth air guide plate 340 is rotatably disposed at the fourth air outlet 240, and the rotation axis of the fourth air guide plate 340 is disposed near the rear edge of the fourth air outlet 240.

[0065] In this embodiment, a third air guide plate 330 is rotatably mounted at the third air outlet 230. When the third air guide plate 330 is open, the airflow blows forward and upward. A fourth air guide plate 340 is rotatably mounted at the fourth air outlet 240. When the fourth air guide plate 340 is open, the airflow blows forward and downward. By adjusting the airflow volume, airflow angle, and airflow speed of the third and fourth air outlets 230 and 240, the airflow volume and air supply range of the indoor unit 100 can be adjusted, enabling the indoor unit 100 to have multiple air supply modes, improving the air supply effect of the indoor unit 100, and thus meeting the different airflow needs of users and improving the user experience.

[0066] Furthermore, in some embodiments of this utility model, such as Figure 3 and Figure 4 As shown, the indoor unit 100 of the air conditioner has multiple air supply modes. For example, during cooling, the first air outlet 210, the second air outlet 220, and the third air outlet 230 are opened, and the indoor unit 100 supplies air to the left, right, and top. The airflow blown out from the top and diffuses downwards, making the indoor temperature distribution more uniform and reducing indoor temperature differences. Furthermore, opening three air outlets during cooling solves the problem of insufficient airflow from the indoor unit 100 during cooling, increasing the air supply range of the indoor unit 100 and thus improving its air supply effect. During heating, the first air outlet 210, the second air outlet 220, and the fourth air outlet 240 are opened, and airflow is supplied from the left, right, and bottom of the indoor unit 100. The airflow blown out from the bottom and diffuses upwards, making the indoor temperature distribution more uniform and reducing indoor temperature differences. Furthermore, by opening three air outlets during heating, the problem of insufficient air volume of the indoor unit 100 during heating is solved, the air outlet range of the indoor unit 100 is increased, and the air outlet effect of the indoor unit 100 is improved.

[0067] In some embodiments of this utility model, such as Figure 4 As shown, the fourth air guide plate 340 can be rotated to a position perpendicular to the fourth air outlet 240. When the fourth air guide plate 340 is perpendicular to the fourth air outlet 240, the inner surface of the fourth air guide plate 340 guides the airflow downward.

[0068] In this embodiment, the fourth air guide plate 340 can be rotated to a vertical position. When the airflow blows out from the fourth air outlet 240, the fourth air guide plate 340 guides the airflow to blow downwards, allowing the airflow to blow downwards a greater distance. This is suitable for the case of the indoor unit 100 of the air conditioner being heated, resulting in better airflow landing effect, improving the comfort of the human body, and enhancing the user experience.

[0069] In some embodiments of this utility model, such as Figure 6As shown, the third air guide plate 330 and the fourth air guide plate 340 are provided with micro-holes 60 so that when the third air guide plate 330 and the fourth air guide plate 340 are in the closed state, the airflow flows out from the micro-holes 60.

[0070] In this embodiment, both the third air guide plate 330 and the fourth air guide plate 340 are provided with micro-holes 60. When the third air outlet 230 and the fourth air outlet 240 are closed, airflow is blown out from the micro-holes 60 of the third air guide plate 330 and the fourth air guide plate 340. After passing through the micro-holes 60, the airflow is more uniform, further improving the uniformity of the airflow from the indoor unit 100. Furthermore, the airflow is dispersed by the micro-holes 60, resulting in a gentler airflow and achieving a windless air delivery effect from the indoor unit 100, further enhancing the user experience.

[0071] In some embodiments of this utility model, such as Figures 2 to 4 As shown, the housing 10 includes a front wall 110, the rear surface of which forms the front cavity wall of the air outlet 130. The front edges of the first air outlet 210, the second air outlet 220, the third air outlet 230, and the fourth air outlet 240 are on the same vertical plane and located on the rear surface of the front wall 110. The rear edges of the first air outlet 210, the second air outlet 220, the third air outlet 230, and the fourth air outlet 240 are on the same vertical plane.

[0072] In this embodiment, the first air outlet 210, the second air outlet 220, the third air outlet 230, and the fourth air outlet 240 have the same width in the front-to-back direction and are arranged relatively neatly. The front edges of the first air outlet 210, the second air outlet 220, the third air outlet 230, and the fourth air outlet 240 are all located on the rear surface of the front wall 110. There is no obstruction when the airflow blows out or diffuses to the front, which makes the airflow diffuse more evenly and fully in the room, resulting in a more uniform temperature distribution in the room, thereby improving the comfort of the human body and enhancing the user experience.

[0073] Furthermore, the rear edges of the first air outlet 210, the second air outlet 220, the third air outlet 230, and the fourth air outlet 240 are all located in the plane of the front surface of the heat exchanger 50, so that the air outlet area of ​​the first air outlet 210, the second air outlet 220, the third air outlet 230, and the fourth air outlet 240 is as large as possible, thereby increasing the air volume of the air conditioner indoor unit 100, improving the air outlet effect of the air conditioner indoor unit 100, and thus improving the user experience.

[0074] In some embodiments of this utility model, the cavity wall of the air outlet cavity 130 is provided with micro-holes 60 that penetrate the housing 10.

[0075] In this embodiment, the upper cavity wall of the air outlet cavity 130 is provided with a first air outlet 210, the lower cavity wall of the air outlet cavity 130 is provided with a second air outlet 220, and micro-holes 60 are provided on the cavity wall of the air outlet cavity 130. When the air conditioner indoor unit 100 is running, airflow is blown out from the first air outlet 210, the second air outlet 220, or the micro-holes 60. The micro-holes 60 compensate for the insufficient airflow from the first air outlet 210 or the second air outlet 220, solving the problem of insufficient airflow from the air conditioner indoor unit 100. Furthermore, after the airflow passes through the micro-holes 60, the airflow is more uniform, improving the uniformity of the airflow from the air conditioner indoor unit 100. The airflow is dispersed by the micro-holes 60, making the airflow gentler when blown out, achieving a windless air supply effect from the air conditioner indoor unit 100, and improving the user experience.

[0076] Furthermore, such as Figure 5 and Figure 6 As shown, the left and right walls of the air outlet cavity 130 are provided with micro-holes 60 that penetrate the housing 10.

[0077] In some embodiments of this utility model, such as Figure 7 As shown, the indoor unit 100 of the air conditioner also includes a partition 70 and a baffle 810. The partition 70 is vertically disposed inside the housing 10, and a through hole is provided on the partition 70, which is correspondingly disposed with the axial flow fan 40. The baffle 810 is disposed in the through hole.

[0078] In this embodiment, a guide vane 810 is provided on the air outlet side of the axial fan 40. Under the action of the axial fan 40, the airflow blown out from the axial fan 40 flows through the guide vane 810 to the air outlet cavity 130, and finally into the room. The airflow blown out from the axial fan 40 passes through the guide vane 810, which improves the airflow distribution, reduces airflow disturbance, and makes the blown airflow flow more smoothly, thereby reducing airflow loss, improving the efficiency of the axial fan 40, and thus improving the air outlet effect of the air conditioner indoor unit 100. Furthermore, by improving the airflow distribution, the noise generated by the airflow can be further reduced, thereby reducing the noise of the air conditioner indoor unit 100 during operation and improving the user experience.

[0079] In some embodiments of this utility model, such as Figure 7 As shown, the indoor unit 100 of the air conditioner also includes an air duct ring 820, which is disposed on the rear surface of the partition 70, and the axial flow fan 40 is disposed inside the air duct ring 820.

[0080] In this embodiment, an air-guiding ring 820 is provided on the partition 70, and the axial flow fan 40 is disposed inside the air-guiding ring 820. The air-guiding ring 820 reduces gap leakage of the axial flow fan 40 and reduces radial airflow loss, thereby improving the air delivery efficiency and performance of the axial flow fan 40, and thus improving the air outlet effect of the indoor unit 100 of the air conditioner.

[0081] In some embodiments of this utility model, such as Figure 7 As shown, the housing 10 includes an air inlet shroud 120, which is located behind the axial flow fan 40. The air inlet shroud 120 includes a rear housing 121 and a side housing 122. The rear housing 121 is vertically arranged. The side housing 122 is inclined and surrounds the rear housing 121. An air inlet 90 is provided on the side housing 122.

[0082] In this embodiment, the air inlet cover 120 includes a rear cover 121 and a side cover 122. The side cover 122 is provided with an air inlet 90, that is, airflow enters from the periphery of the air conditioner indoor unit 100.
