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 an air outlet cavity. Background Technology
[0002] A wall-mounted air conditioner indoor unit is a type of air conditioner indoor unit that is suspended from a wall. To improve the airflow efficiency of the indoor unit, some wall-mounted air conditioners have an upper air outlet on the front wall of the casing, with an upper air guide plate rotatably mounted at the upper air outlet. A lower air outlet is located on the lower part of the front wall, with a lower air guide plate rotatably mounted at the lower air outlet. When heating, the upper air outlet is closed, allowing hot air to escape through the lower air outlet. When cooling, the lower air outlet is closed, allowing cold air to escape through the upper air outlet. However, when the upper or lower air outlet is closed, the airflow blows vertically onto the upper or lower air guide plate or the inner surface of the front wall, easily creating vortices at the upper or lower air outlet. This increases airflow loss and reduces the airflow volume of the wall-mounted air conditioner indoor unit. Utility Model Content

[0054] 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 7 The arrows in the diagram indicate the direction of airflow. This utility model provides an indoor air conditioning unit 100 with an air outlet cavity, including a housing 10, a first air guide plate 310, a second air guide plate 320, and an axial flow fan 40. The housing 10 defines an air outlet cavity 130. A first air outlet 210 communicating with the upper part of the air outlet cavity 130 and a second air outlet 220 communicating with the lower part of the air outlet cavity 130 are formed on the front surface of the housing 10. The first air outlet 210 is located above the second air outlet 220, and the first and second air outlets 210 are spaced apart. The front surface of the air outlet cavity 130 protrudes forward. The first air guide plate 310 is disposed at the first air outlet 210 to open or close the first air outlet 210. The second air guide plate 320 is disposed at the second air outlet 220 to open or close the second air outlet 220. An axial flow fan 40 is located at the rear of the air outlet cavity 130, and the axial flow fan 40 is configured to blow airflow into the air outlet cavity 130 at its front.
[0055] 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 disposed at the first air outlet 210, and a second air guide plate 320 is 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, and the second air outlet 220 is fully open. Alternatively, when the indoor unit 100 of the air conditioner is cooling, the second air outlet 220 is closed, and the first air outlet 210 is fully open.
[0056] When the first air outlet 210 is closed, the airflow blows into the air outlet cavity 130 and flows along the front surface of the air outlet cavity 130. When the airflow reaches the second air outlet 220, it is sent outward. When the second air outlet 220 is closed, the airflow blows into the air outlet cavity 130 and flows along the front surface of the air outlet cavity 130. When the airflow reaches the first air outlet 210, it is sent outward. The air outlet cavity 130 is vertically positioned relative to its front surface, and the front surface of the air outlet cavity 130 protrudes forward. This causes the airflow to flow forward and downward or forward and upward along the front surface of the air outlet cavity 130 after it reaches the air outlet cavity 130. This prevents the airflow from forming vortices inside the first air outlet 210 or the second air outlet 220, reduces airflow resistance, reduces airflow loss, thereby increasing the air volume of the indoor unit 100, improving the airflow effect of the indoor unit 100, and enhancing the user experience.
[0057] 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.
[0058] In some embodiments of this utility model, such as Figures 2 to 6 As shown, the housing 10 includes a top wall 140 at the top and a bottom wall 150 at the bottom. The upper edge of the first air outlet 210 is located behind the lower edge of the first air outlet 210, and the upper edge of the first air outlet 210 is located at the front end of the front surface of the top wall 140. The upper edge of the second air outlet 220 is located in front of the lower edge of the second air outlet 220, and the lower edge of the second air outlet 220 is located at the front end of the front surface of the bottom wall 150.
[0059] In this embodiment, the first air outlet 210 and the second air outlet 220 are inclined. The first air outlet 210 is inclined upwards from front to back, and the second air outlet 220 is inclined downwards from front to back. When the first air guide plate 310 closes the first air outlet 210, the first air guide plate 310 is inclined upwards from front to back, meaning that when the first air outlet 210 is closed, the airflow flows forward and downward along the inner surface of the first air guide plate 310. When the second air guide plate 320 closes the second air outlet 220, the second air guide plate 320 is inclined downwards from front to back, meaning that when the second air outlet 220 is closed, the airflow flows forward and upward along the inner surface of the second air guide plate 320. When the first air outlet 210 or the second air outlet 220 supplies air individually, vortices are avoided on the inner side of the first air guide plate 310 or the second air guide plate 320, reducing airflow resistance and airflow loss, thereby increasing the air volume of the indoor unit 100, and thus improving the air supply effect of the indoor unit 100 and enhancing the user experience.
[0060] Furthermore, the first air outlet 210 is located at the corner between the front surface of the housing 10 and the top wall 140, and the second air outlet 220 is located at the corner between the front surface of the housing 10 and the bottom wall 150. Airflow is blown out from the first air outlet 210 to the front, upper front, and upper side, and airflow is blown out from the second air outlet 220 to the front, lower front, and lower side, increasing the angle of airflow and thus improving the air outlet angle of the air conditioner indoor unit 100 and improving the air outlet effect of the air conditioner indoor unit 100.
[0061] In some embodiments of this utility model, such as Figures 2 to 5 As shown, the housing 10 includes a front panel 110, the rear surface of which is the front surface of the air outlet cavity 130. The rear surface of the front panel 110 includes a first air guiding region 160 and a second air guiding region 170, with the first air guiding region 160 located above the second air guiding region 170. The first air guiding region 160 is inclined upwards from front to back. The second air guiding region 170 is inclined downwards from front to back.
[0062] In this embodiment, the rear surface of the front panel 110 serves as the front surface of the air outlet cavity 130, and the rear surface of the front panel 110 guides the airflow from the axial flow fan 40. The rear surface of the front panel 110 includes a first air guiding region 160 and a second air guiding region 170. The first air guiding region 160 guides air downwards and forwards, and the second air guiding region 170 guides air upwards and forwards. When the first air outlet 210 is closed, the axial flow fan 40 blows airflow into the air outlet cavity 130, and the airflow flows downwards and forwards along the first air guiding region 160 and exits from the second air outlet 220. When the second air outlet 220 is closed, the axial flow fan 40 blows airflow into the air outlet cavity 130, and the airflow flows upwards and forwards along the second air guiding region 170 and exits from the first air outlet 210. By using the inclined first air guide area 160 and second air guide area 170, when the first air outlet 210 or the second air outlet 220 supplies air alone, vortices are avoided on the inner side of the first air guide plate 310 or the second air guide plate 320, reducing airflow resistance and airflow loss, thereby increasing the air volume of the air conditioner indoor unit 100, and thus improving the air supply effect of the air conditioner indoor unit 100 and enhancing the user experience.
[0063] In some embodiments of this utility model, such as Figures 2 to 5 As shown, the front panel 110 includes a first inclined plate 111, a second inclined plate 113, and a vertical plate 112. The first inclined plate 111 is inclined upwards from front to back. The second inclined plate 113 is inclined downwards from front to back. The vertical plate 112 is vertically arranged, with its upper end connected to the first inclined plate 111 and its lower end connected to the second inclined plate 113. The rear surface of the first inclined plate 111 forms a first air guiding area 160, and the rear surface of the second inclined plate 113 forms a second air guiding area 170.
[0064] In this embodiment, the front panel 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 panel 110 that protrudes forward. The forward protrusion of the air guide surface 130 is achieved by the arrangement of the first inclined plate 111, the vertical plate 112, and the second inclined plate 113. The front panel 110 has a simple structure and a relatively aesthetically pleasing appearance.
[0065] In some embodiments of this utility model, the angle between the first inclined plate 111 and the vertical plate 112 is 160° to 170°, and the angle between the second inclined plate 113 and the vertical plate 112 is 160° to 170°.
[0066] In this embodiment, the angles between the first inclined plate 111 and the vertical plate 112, and between the second inclined plate 113 and the vertical plate 112, are relatively large. This results in a smoother airflow from the first inclined plate 111 and the second inclined plate 113 to the vertical plate 112, preventing airflow disturbance, reducing airflow loss, and thus improving the air outlet performance of the indoor unit 100 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°. The angle between the second inclined plate 113 and the vertical plate 112 is also 160°, 165°, or 170°.
[0067] Preferably, the angle between the first inclined plate 111 and the vertical plate 112 is 165°. The angle between the second inclined plate 113 and the vertical plate 112 is also 165°.
[0068] In some embodiments of this utility model, such as Figures 2 to 5 As shown, the connection between the first inclined plate 111 and the vertical plate 112 has a rounded corner transition. The connection between the second inclined plate 113 and the vertical plate 112 also has a rounded corner transition.
[0069] 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, so that the airflow is smoother when flowing along the first inclined plate 111, the vertical plate 112 and the second inclined plate 113, preventing airflow disturbance, reducing airflow loss, thereby improving the air outlet effect of the air conditioner indoor unit 100 and improving the user experience.
[0070] 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.
[0071] In this embodiment, the widths of the first inclined plate 111, the vertical plate 112, and the second inclined plate 113 are equal. The structure of the front plate 110 is symmetrical vertically, and the airflow is more stable when flowing on the rear surface of the front plate 110, thus improving the air outlet effect of the air conditioner indoor unit 100. Furthermore, the symmetrical design of the front plate 110 makes the appearance of the air conditioner indoor unit 100 more aesthetically pleasing.
[0072] In some embodiments of this utility model, such as Figures 2 to 6 As shown, the first air guide plate 310 is slidably disposed at the first air outlet 210. The second air guide plate 320 is slidably disposed at the second air outlet 220.
[0073] In this embodiment, the first air outlet 210 and the second air outlet 220 can simultaneously supply air into the room, increasing the air volume of the indoor unit 100. Alternatively, the first air guide plate 310 opens a portion of the first air outlet 210, and the second air guide plate 320 opens a portion of the second air outlet 220, increasing the airflow velocity and thus increasing the air delivery distance of the indoor unit 100. The air outlet area of the first air outlet 210 and the air outlet area of the second air outlet 220 can be equal or unequal. Alternatively, when the indoor unit 100 is heating, the first air outlet 210 is closed, and the second air outlet 220 is fully open. Alternatively, when the indoor unit 100 is cooling, the second air outlet 220 is closed, and the first air outlet 210 is fully open.
[0074] The first air guide plate 310 and the second air guide plate 320 are slidably configured. By sliding them to different positions, the air outlet area of the first air outlet 210 and the second air outlet 220 can be adjusted, thereby controlling the air volume of the indoor unit 100. As the air outlet area gradually increases, the airflow velocity decreases, and the air delivery distance of the indoor unit 100 decreases. Conversely, as the air outlet area gradually decreases, the airflow velocity increases, and the air delivery distance of the indoor unit 100 increases. By slidably adjusting the air outlet area through the first air outlet 210 and the second air outlet 220, the air volume, airflow velocity, and air delivery distance of the indoor unit 100 can be easily controlled. This simple control method enhances the user experience. Furthermore, by adjusting the air volume, airflow velocity, and air delivery distance of the indoor unit 100, different user air delivery needs can be met, further improving the user experience.
[0075] In some embodiments of this utility model, the first air guide plate 310 is slidably disposed on the inner or outer side of the first inclined plate 111, and the second air guide plate 320 is slidably disposed on the inner or outer side of the second inclined plate 113. When the first air guide plate 310 is located inside the first inclined plate 111, the ratio of the width of the first air guide plate 310 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 guide plate 310 to the width of the first inclined plate 111 is 4 / 5 and 1. When the second air guide plate is located inside the second inclined plate 113, the ratio of the width of the second air guide plate 320 to the width of the second inclined plate 113 is 4:5 to 1:1. For example, the ratio of the width of the second air guide plate 320 to the width of the second inclined plate 113 is 4 / 5 and 1.
[0076] In this embodiment, the first air guide plate 310 slides downward to open the first air outlet 210, and slides upward to close the first air outlet 210. The second air guide plate 320 slides upward to open the second air outlet 220, and slides downward to close the second air outlet 220. When the first air guide plate 310 is fully open, the first air guide plate 310 is below the first air outlet 210, and the length of the first inclined plate 111 is set to provide sufficient placement space for the first air guide plate 310. When the second air guide plate 320 is fully open, the second air guide plate 320 is above the second air outlet 220, and the length of the second inclined plate 113 is set to provide sufficient placement space for the second air guide plate 320.
[0077] Preferably, the ratio of the width of the first air guide plate 310 to the width of the first inclined plate 111 is 1. The ratio of the width of the second air guide plate 320 to the width of the second inclined plate 113 is 1.
[0078] In some embodiments of this utility model, such as Figure 6 As shown, the rear surface of the front panel 110 is a forward-convex arc shape. The upper edge of the first air guiding area 160 is located at the lower edge of the first air outlet 210, and the lower edge of the first air guiding area 160 is located at the foremost position of the rear surface of the front panel 110. The upper edge of the second air guiding area 170 is located at the foremost position of the rear surface of the front panel 110, and the lower edge of the second air guiding area 170 is located at the upper edge of the second air outlet 220.
[0079] In this embodiment, the first air guiding area 160 guides air downwards and forwards, while the second air guiding area 170 guides air upwards and forwards. When the first air outlet 210 is closed, the axial fan 40 blows airflow into the air outlet cavity 130, and the airflow flows downwards and forwards along the first air guiding area 160 and exits through the second air outlet 220. When the second air outlet 220 is closed, the axial fan 40 blows airflow into the air outlet cavity 130, and the airflow flows upwards and forwards along the second air guiding area 170 and exits through the first air outlet 210. By using the inclined first air guiding area 160 and second air guiding area 170, when the first air outlet 210 or the second air outlet 220 supplies air alone, vortices are avoided on the inner side of the first air guide plate 310 or the second air guide plate 320, reducing airflow resistance and airflow loss, thereby increasing the air volume of the indoor unit 100 and improving the air supply effect of the indoor unit 100, thus enhancing the user experience.
[0080] In some embodiments of this utility model, such as Figure 7As shown, there are two axial flow fans 40, which are arranged horizontally and housed within the casing 10. The indoor unit 100 of the air conditioner also includes a heat exchanger 50, which is located within the casing 10 and at the air inlet of the air outlet cavity 130.
[0081] 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.
[0082] In some embodiments of this utility model, such as Figure 6 and Figure 7 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.
[0083] 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.
[0084] In some embodiments of this utility model, such as Figure 6 and Figure 7 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.
[0085] 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.
[0086] In some embodiments of this utility model, such as Figures 2 to 7As shown, the housing 10 also 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 60 is provided on the side housing 122.
[0087] 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.
[0088] 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.
[0089] Preferably, in some embodiments of this utility model, the air conditioner indoor unit 100 is a wall-mounted air conditioner indoor unit.
