Description

Technical Field

[0001] This utility model relates to the field of air conditioner technology, and in particular to an air conditioner indoor unit with a front wall that can guide airflow. Background Technology

[0002] A wall-mounted air conditioner indoor unit is a type of air conditioner indoor unit that is suspended from 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, guiding the airflow to a specific location can easily cause uneven indoor temperature distribution and airflow loss, thus reducing the airflow efficiency of the indoor unit and affecting the user experience.

[0045] Figure 1 This is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the present invention, such as... Figure 1 As shown, and with reference Figures 2 to 6 The arrows in the diagram indicate the direction of airflow. This embodiment of the invention provides an air conditioning indoor unit 100 with a front-wall directional airflow, including a housing 10 and a first air guide plate 310. The housing 10 includes a front wall 110, with a first air outlet 210 located at its upper part. The front surface of the front wall 110 includes a first air guiding region 130, the upper edge of which is the lower edge of the first air outlet 210, and the lower edge of the first air guiding region 130 is located at the lower front side of the upper edge of the first air guiding region 130. The first air guide plate 310 is disposed at the first air outlet 210 and configured to at least guide the airflow from the first air outlet 210 forward and downward.

[0046] In this embodiment, the front side of the indoor unit 100 includes a front wall 110, and the front surface of the front wall 110 includes a first air guiding area 130, which guides the airflow to flow forward and downward. A first air outlet 210 is provided at the upper part of the front wall 110, and a first air guide plate 310 is provided at the first air outlet 210. The first air guide plate 310 guides at least the airflow from the first air outlet 210 forward and downward. Guided by the first air guide plate 310, the airflow blows forward and downward from the first air outlet 210, and then the heat exchange airflow flows forward and downward along the first air guiding area 130. Especially when the indoor unit 100 is heating, after the hot airflow is blown out from the first air outlet 210, it flows forward and downward along the first air guiding area 130. The hot air descends, making the indoor temperature distribution more uniform, preventing temperature differences, and improving the user experience. Moreover, after the airflow exits the first air outlet 210, it flows along the first air guide area 130. The upper end of the first air guide area 130 is in the same direction as the heat exchange airflow guided by the first air guide plate 310, so that the heat exchange airflow adheres to the first air guide area 130 after exiting the first air outlet 210, reducing the loss of heat exchange airflow, 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.

[0047] Furthermore, the first air guide plate 310 can guide the airflow of the first air outlet 210 to the forward, downward, or upward side. That is, the first air guide plate 310 has multiple movement positions. For example, the multiple movement positions include a first movement position, a second movement position, and a third movement position. When the first air guide plate 310 closes the first air outlet 210, the upper edge and lower edge of the first air guide plate 310 are respectively the first edge and the second edge. At the first movement position, the first edge of the first air guide plate 310 is located at the downward front side of the second edge, meaning the first air guide plate 310 guides the airflow at the first air outlet 210 to the downward forward side. At the second movement position, the first edge of the first air guide plate 310 is located at the front side of the second edge, meaning the first air guide plate 310 guides the airflow at the first air outlet 210 to the forward side. At the third movement position, the first edge of the first air guide plate 310 is located at the upward front side of the second edge, meaning the first air guide plate 310 guides the airflow at the first air outlet 210 to the upward forward side.

[0048] In some embodiments of this utility model, such as Figures 2 to 5 As shown, the first air guiding area 130 is a plane or an arc surface that bulges forward and upward.

[0049] In this embodiment, the first air guiding area 130 is a flat surface or a forward-convex arc surface to guide the airflow to flow forward and downward.

[0050] In some embodiments of this utility model, such as Figures 2 to 4As shown, the front surface of the front wall also includes a vertical region and an inclined region. The indoor unit of the air conditioner also includes a second air outlet 220 and a second air guide plate 320. The second air outlet 220 is disposed at the lower part of the front wall 110. The second air guide plate 320 is rotatably disposed at the second air outlet 220 and is used to guide the airflow exiting the second air outlet 220.

[0051] In this embodiment, the indoor unit 100 of the air conditioner includes a first air outlet 210 and a second air outlet 220. The first air outlet 210 is disposed above the second air outlet 220. 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. Through the cooperation of the first air outlet 210 and the second air outlet 220, the indoor unit 100 of the air conditioner has multiple air supply modes. The first air outlet 210 and the second air outlet 220 can simultaneously supply air to the room, increasing the air volume of the indoor unit 100. Alternatively, when the indoor unit 100 of the air conditioner is heating, the first air outlet 210 is closed, the second air outlet 220 is open, and the second air guide plate 320 guides the hot airflow to blow forward and downward. Alternatively, when the indoor unit 100 of the air conditioner is cooling, the second air outlet 220 is closed, the first air outlet 210 is open, and the first air guide plate 310 guides the cold airflow to blow forward and upward. By cooperating with the first air outlet 210 and the second air outlet 220, the air volume of the indoor unit 100 of the air conditioner is increased, or the indoor temperature is distributed more evenly, thereby meeting the various air blowing needs of users and improving the user experience.

[0052] Furthermore, in some embodiments of this utility model, such as Figures 2 to 4 As shown, the first air guide plate 310 adopts an inward rotation mode, and the second air guide plate 320 adopts an outward rotation mode.

[0053] In this embodiment, the first air guide plate 310 rotates inward. When the first air guide plate 310 opens the first air outlet 210, the edge of the first air outlet 210 restricts the rotation angle of the first air guide plate 310, preventing cold air from rising too high and preventing cold air backflow when the indoor unit 100 of the air conditioner is cooling. The second air guide plate 320 rotates outward. When the second air guide plate 320 opens the second air outlet 220, the second air guide plate 320 can rotate to the front of the front wall 110, preventing the second air guide plate 320 from affecting the airflow.

[0054] In some embodiments of this utility model, such as Figures 2 to 4As shown, the front wall 110 includes a first inclined plate 111, a vertical plate 112, and a second inclined plate 113. The first inclined plate 111 is inclined upwards from front to back. The vertical plate 112 is vertically arranged, and its upper end is connected to the first inclined plate 111. The second inclined plate 113 is located at the lower end of the vertical plate 112 and is inclined downwards from front to back. The front surface of the first inclined plate 111 forms a first air guiding area 130, the front surface of the vertical plate 112 forms a vertical area 140, and the front surface of the second inclined plate 113 forms an inclined area 150.

[0055] In this embodiment, the front wall 110 is composed of a first inclined plate 111, a vertical plate 112, and a second inclined plate 113. The first inclined plate 111 is inclined forward and downward. The upper end of the vertical plate 112 is connected to the lower end of the first inclined plate 111, and the lower end of the vertical plate 112 is connected to the upper end of the second inclined plate 113. The second inclined plate 113 is inclined backward and downward. The first inclined plate 111, the vertical plate 112, and the second inclined plate 113 are connected to form a front wall 110 protruding forward. The front surface of the first inclined plate 111 forms a first air guiding region 130, which guides air forward and downward. The front surface of the vertical plate 112 forms a vertical region 140, which guides air downward. The front surface of the second inclined plate 113 forms an inclined region 150.

[0056] When the indoor unit 100 of the air conditioner is cooling, the second air outlet 220 is closed, and the first air guide plate 310 guides the cold airflow to blow forward and upward from the first air outlet 210. When the indoor unit 100 of the air conditioner is heating, the second air guide plate 320 guides the hot airflow to blow forward and downward from the second air outlet 220. The first air guide plate 310 guides the hot airflow to blow forward and downward from the first air outlet 210. The opening angle of the first air guide plate 310 is small, so that the hot airflow from the first air outlet 210 flows downward along the first air guiding area 130, and then flows downward through the vertical area 140, making the indoor temperature distribution more uniform, preventing temperature differences in the room, and improving the user experience. By using the first air guide area 130 to guide airflow forward and downward, the hot airflow is guided when the indoor unit 100 is heating. The hot airflow flows out from the first air outlet 210 and the second air outlet 220, increasing the air volume of the indoor unit 100 and thus improving its airflow performance and user experience. Furthermore, after exiting the first air outlet 210, the heat exchange airflow continues to flow along the first air guide area 130. The first air guide plate 310 follows the same flow direction as the heat exchange airflow guided by the first air guide area 130, ensuring that the heat exchange airflow adheres to the first air guide area 130 after exiting the first air outlet 210, reducing heat exchange airflow loss and further increasing the air volume of the indoor unit 100, improving its airflow performance and ultimately enhancing the user experience.

[0057] In some embodiments of this utility model, the angle between the first inclined plate 111 and the vertical plate 112 is 160° to 170°.

[0058] In this embodiment, the angle between the first inclined plate 111 and the vertical plate 112 is relatively large, making the airflow from the first inclined plate 111 to the vertical plate 112 relatively smooth, preventing airflow disturbance, reducing airflow loss, and thus improving the air outlet effect of the indoor unit 100 of the air conditioner and enhancing the user experience. For example, the angle between the first inclined plate 111 and the vertical plate 112 is 160°, 165°, or 170°.

[0059] Preferably, the angle between the first inclined plate 111 and the vertical plate 112 is 165°.

[0060] In some embodiments of this utility model, such as Figures 2 to 4 As shown, the connection between the first inclined plate 111 and the vertical plate 112 is rounded. The connection between the second inclined plate 113 and the vertical plate 112 is also rounded.

[0061] In this embodiment, the connection between the first inclined plate 111 and the vertical plate 112 is relatively rounded, and the connection between the second inclined plate 113 and the vertical plate 112 is relatively rounded. This makes the airflow smoother when it flows along the front surface of the first inclined plate 111, the vertical plate 112 and the second inclined plate 113, further preventing airflow disturbance, reducing airflow loss, and thus improving the air outlet effect of the air conditioner indoor unit 100 and enhancing the user experience.

[0062] In some embodiments of this utility model, the first air outlet 210 is located on the upper part of the first inclined plate 111, and the ratio of the width of the first air outlet 210 to the width of the first inclined plate 111 is 4 / 5 to 1. For example, the ratio of the width of the first air outlet 210 to the width of the first inclined plate 111 is 4 / 5 or 1.

[0063] In this embodiment, the airflow flows along the first air guide region 130 when it is blown out from the first air outlet 210, and the first inclined plate 111 guides the flow of the airflow. Therefore, while increasing the air outlet area of ​​the first air outlet 210, it is also necessary to ensure the width of the first air guide region 130, that is, the width of the first inclined plate 111, so that the first air guide region 130 guides the flow of the airflow, reduces the outward dispersion of the airflow, and makes the airflow have a certain speed when flowing from the first inclined plate 111 to the vertical plate 112, so that the airflow can diffuse downward as much as possible, thereby reducing the difference in indoor temperature distribution.

[0064] Preferably, the ratio of the width of the first air outlet 210 to the width of the first inclined plate 111 is 1. That is, the width of the first air outlet 210 is equal to the width of the first inclined plate 111, which increases the air outlet area of ​​the first air outlet 210 and thus increases the air volume of the air conditioner indoor unit 100. Moreover, the arrangement of the first air outlet 210 is relatively neat, and the appearance of the air conditioner indoor unit 100 is more aesthetically pleasing.

[0065] In some embodiments of this utility model, the width of the first inclined plate 111, the width of the vertical plate 112, and the width of the second inclined plate 113 are equal.

[0066] In this embodiment, the widths of the first inclined plate 111, the vertical plate 112, and the second inclined plate 113 are equal, and the structure of the front wall 110 is symmetrical vertically. The airflow is more stable when flowing on the rear surface of the front wall 110, thus improving the air outlet effect of the air conditioner indoor unit 100. Furthermore, the symmetrical design of the front wall 110 makes the appearance of the air conditioner indoor unit 100 more aesthetically pleasing.

[0067] In some embodiments of this utility model, such as Figure 5 As shown, the front surface of the front wall 110 is arc-shaped, and the lower edge of the first air guiding area 130 is located at the foremost position of the front surface of the front wall 110.

[0068] In this embodiment, the front wall 110 is arc-shaped, and the lower edge of the first air guiding area 130 is located at the foremost position of the front surface of the front wall 110. That is, the first air guiding area 130 is an arc surface that bulges forward and upward, and the cross-section of the lower edge of the first air guiding area 130 is a vertical surface. When the indoor unit 100 of the air conditioner is heating, the hot airflow blown out from the first air outlet 210 flows forward and downward along the first air guiding area 130 and then flows downward. The hot air flows downward, making the indoor temperature distribution more uniform, preventing temperature differences, and improving the user experience. Moreover, after the heat exchange airflow exits the first air outlet 210, it flows along the first air guiding area 130. The airflow adheres to the first air guiding area 130, reducing the loss of heat exchange airflow, thereby increasing the air volume of the indoor unit 100 of the air conditioner, improving the air outlet effect of the indoor unit 100, and thus improving the user experience.

[0069] In some embodiments of this utility model, such as Figures 2 to 5 As shown, the indoor unit 100 of the air conditioner also includes an axial flow fan 40, which is located on the inner side of the front wall 110 and discharges air horizontally to the front side.

[0070] In this embodiment, an axial flow fan 40 delivers air to the outside. Compared to a cross-flow fan, the axial flow fan 40 can provide a larger air volume during operation, further increasing the air output of the indoor unit 100. Furthermore, 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 improving the user experience.

[0071] Furthermore, when the indoor unit 100 of the air conditioner is running, the axial fan 40 blows air forward, and the airflow blows to the second air guide area 160. Then the airflow flows along the second air guide area 160 to the first air outlet 210 or the second air outlet 220. The second air guide area 160 guides the airflow.

[0072] In some embodiments of this utility model, such as Figures 2 to 5 As shown, the rear surface of the front wall 110 forms a second air guiding region 160 to guide the airflow blown out by the axial flow fan 40. The rear surface of the front wall 110 is arranged parallel to the front surface of the front wall 110.

[0073] In this embodiment, the second air guiding region 160 is at least parallel to the first air guiding region 130, meaning the second air guiding region guides air at least forward and downward. When the first air outlet 210 is closed, the airflow blows onto the inner surface of the first air guiding plate 310 and the second air guiding region 160. The airflow blowing onto the first air guiding plate 310 flows forward and downward along the first air guiding plate 310 and the second air guiding region 160. This prevents the airflow from forming vortices on the inner side of the first air guiding plate 310, reduces airflow resistance, thereby increasing the air volume of the indoor unit 100, and thus improving the airflow effect of the indoor unit 100, enhancing the user experience.

[0074] Furthermore, such as Figures 2 to 5 As shown, the second air guide area 160 protrudes forward.

[0075] In this embodiment, when the first air outlet 210 is closed, the airflow blows onto the inner surface of the first air guide plate 310 and the second air guide area 160. The airflow blowing onto the first air guide plate 310 flows forward and downward along the first air guide plate 310 and the second air guide area 160. When the second air outlet 220 is closed, the airflow blows onto the inner surface of the second air guide plate 320 and the second air guide area 160. The airflow blowing onto the second air guide plate 320 flows forward and upward along the second air guide plate 320 and the second air guide area 160. Since the second air guide area 160 has a forward-convex inward curved structure, it avoids the formation of vortices in the airflow inside the first air guide plate 310 or the second air guide plate 320, reduces airflow resistance, thereby increasing the air volume of the air conditioner indoor unit 100, and thus improving the air outlet effect of the air conditioner indoor unit 100 and enhancing the user experience.

[0076] In some embodiments of this utility model, such as Figures 2 to 6As shown, the indoor unit 100 of the air conditioner also includes an air inlet cover 120. The air inlet cover 120 is located on the air inlet side of the axial flow fan 40. The air inlet cover 120 includes a rear housing 121 facing the rear and a side housing 122. The side housing 122 is inclined and surrounds the rear housing 121. An air inlet 60 is provided on the side housing 122.

[0077] 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 60, that is, airflow enters from the periphery of the air conditioner indoor unit 100.

[0078] In some embodiments of this utility model, such as Figures 2 to 6 As shown, the indoor unit 100 of the air conditioner also includes a heat exchanger 50, which is located in front of the axial flow fan 40.

[0079] 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 60, the air inlet area of ​​the air inlet 60 can be made as large as possible, thereby increasing the air intake volume of the air conditioner indoor unit 100, and thus increasing the air output volume of the air conditioner indoor unit 100.

[0080] In some embodiments of this utility model, such as Figure 6 As shown, the indoor unit 100 of the air conditioner also includes a partition 70 and a baffle 80. The partition 70 has a through hole, which is corresponding to the axial flow fan 40. The baffle 80 is disposed in the through hole.

[0081] In this embodiment, a guide vane 80 is provided on the air outlet side of the axial fan 40. The airflow blown out from the axial fan 40 passes through the guide vane 80, 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.

[0082] In some embodiments of this utility model, such as Figure 6 As shown, multiple axial flow fans 40 are arranged horizontally side by side. Multiple guide vanes 80 are also provided, with each guide vane 80 corresponding to one of the axial flow fans 40.

[0083] In this embodiment, the indoor unit 100 of the air conditioner is equipped with multiple axial flow fans 40, and each axial flow fan has a guide grille 80 at its air outlet. The multiple axial flow fans 40 blow air forward, increasing the air volume of the indoor unit 100 of the air conditioner, thereby improving the air outlet effect of the indoor unit 100 of the air conditioner.

[0084] Furthermore, two axial flow fans 40 are provided.

[0085] In some embodiments of this utility model, such as Figures 2 to 6 As shown, the indoor unit 100 of the air conditioner also includes an air duct ring 90, which is disposed on the side of the partition 70 near the axial flow fan 40, and the axial flow fan 40 is disposed inside the air duct ring 90.

[0086] In this embodiment, an air-guiding ring 90 is provided on the partition 70, and the axial flow fan 40 is disposed inside the air-guiding ring 90. The air-guiding ring 90 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.

[0087] In some embodiments of this utility model, the air conditioner indoor unit 100 is a wall-mounted air conditioner indoor unit, a floor-standing air conditioner indoor unit, or other air conditioner indoor units.

[0088] Preferably, in some embodiments of this utility model, the air conditioner indoor unit 100 is a wall-mounted air conditioner indoor unit.
