Description

Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to an air conditioner. Background Technology

[0002] Air conditioners regulate the temperature of indoor air in buildings, vehicles, and other environments to improve user comfort. However, existing air conditioner deflectors have limited adjustment range and insufficient air delivery distance. Furthermore, the deflectors cause airflow loss when the air is expelled, affecting the air conditioner's performance. Summary of the Invention

[0003] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes an air conditioner that delivers air over a long distance.

[0004] An air conditioner according to an embodiment of the present invention includes: a housing, wherein an air outlet duct is defined within the housing, the air outlet duct having an air outlet located on the housing, the housing including a first air duct plate and a second air duct plate that define the air outlet duct and are disposed opposite to each other; and an air guide plate, the air guide plate being rotatably disposed at the air outlet to open or close the air outlet, the air conditioner having a long-distance air supply mode, wherein in the long-distance air supply mode, at least a portion of the air guide plate is located within the air outlet duct and the air inlet end of the air guide plate abuts against the first air duct plate, and the air outlet end of the air guide plate is spaced apart from both the first air duct plate and the second air duct plate.

[0005] According to an embodiment of the air conditioner of the present invention, an air guide plate is rotatably disposed at the air outlet to open or close the air outlet. In long-distance air delivery mode, by configuring at least a portion of the air guide plate within the air outlet duct, with the air inlet end of the air guide plate abutting against a first air duct plate, and the air outlet end of the air guide plate spaced apart from both the first and second air duct plates, the actual air outlet area is narrower in the direction from the first to the second air duct plate compared to the distance between the first and second air duct plates. This reduces the actual air delivery area of ​​the air outlet, thereby increasing airflow pressure and extending the air delivery distance, achieving long-distance air delivery. Furthermore, since the air inlet end of the air guide plate abuts against the first air duct plate, all the airflow exiting the air outlet flows along the air guide plate, further reducing airflow loss and maximizing the airflow volume without changing the cooling or heating capacity, further increasing the air delivery distance of the air conditioner.

[0006] In some embodiments of the present invention, in the long-distance air supply state, the distance between the air outlet end of the air guide plate and the second air duct plate is less than the distance between the air inlet end of the air guide plate and the second air duct plate.

[0007] In some embodiments of the present invention, in the long-distance air supply state, the distance between the air guide plate and the second air duct plate gradually decreases.

[0008] In some embodiments of the present invention, in the long-distance air supply state, the air guide plate is formed as a curved plate that is concave toward the first air duct plate.

[0009] In some embodiments of the present invention, the housing includes a volute and a volute tongue, at least a portion of the volute tongue being formed as the first air duct plate, and at least a portion of the volute being formed as the second air duct plate.

[0010] In some embodiments of the present invention, the air conditioner also has a maximum air supply state, in which at least a portion of the air guide plate is located within the air outlet duct, and the air inlet and air outlet ends of the air guide plate are spaced apart from the first air duct plate and the second air duct plate.

[0011] In some embodiments of the present invention, in the maximum air supply state, the distance between the air inlet end of the air guide plate and the first air duct plate is less than the distance between the air inlet end of the air guide plate and the second air duct plate.

[0012] In some embodiments of the present invention, the invention further includes a motor disposed on the inner wall of the air outlet duct, and the motor is directly connected to the air guide plate.

[0013] In some embodiments of the present invention, a connecting arm is provided on one side of the air guide plate, and the motor is directly connected to the connecting arm.

[0014] In some embodiments of the present invention, the motor is a single unit.

[0015] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0030] An air conditioner 100 according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0031] like Figure 1 As shown, an air conditioner 100 according to an embodiment of the present invention includes a housing 1 and an air guide plate 2.

[0032] Specifically, an air outlet duct 11 is defined within the housing 1. The air outlet duct 11 has an air outlet 111 located on the housing 1. The housing 1 includes a first air duct plate 141 and a second air duct plate 131 that define the air outlet duct 11 and are disposed opposite to each other. It is understood that the housing 1 includes the first air duct plate 141 and the second air duct plate 131 that are disposed opposite to each other, defining the air outlet duct 11. The air conditioner 100 has cooling and heating functions and can achieve cooling or heating according to the user's needs. Specifically, an air inlet 12 is provided on the housing 1. At least a portion of the impeller 5 is disposed within the air outlet duct 11. A heat exchange device 4 is also provided within the housing 1. Along the airflow direction, the heat exchange device 4 is located upstream of the impeller 5, and at least a portion of the heat exchange device 4 is opposite to the air inlet 12. Figure 1 In the example shown, the heat exchange device 4 is arranged to partially surround the impeller 5. Driven by the impeller 5, the airflow enters the housing 1 through the air inlet 12. After exchanging heat with the heat exchange device 4, the airflow is discharged from the air outlet 111 through the air outlet 111.

[0033] The air guide vane 2 is rotatably mounted at the air outlet 111 to open or close the air outlet 111. It is understood that when the air conditioner 100 is in the off state, such as... Figure 1 As shown, the air guide plate 2 is in its initial position to close the air outlet 111, preventing debris from entering the air conditioner 100 and improving the overall appearance and aesthetics of the air conditioner 100 when it is off. When the air conditioner 100 is running, the air guide plate 2 rotates to open the air outlet 111. The rotation of the air guide plate 2 can adjust the air outlet angle, air outlet range, and air delivery distance at the air outlet 111, so that the air conditioner 100 has multiple air delivery modes, such as long-distance air delivery or maximum range air delivery, thereby meeting different user needs.

[0034] like Figure 2As shown, the air conditioner 100 has a long-distance air supply mode. When the air conditioner 100 is in the long-distance air supply mode, at least a portion of the air guide plate 2 is located within the air outlet duct 11, and the air inlet end 21 of the air guide plate 2 abuts against the first air duct plate 141. The air outlet end 22 of the air guide plate 2 is spaced apart from both the first air duct plate 141 and the second air duct plate 131. It can be understood that when the airflow flows within the air outlet duct 11 to the air inlet end 21 of the air guide plate 2, the airflow flows towards the air outlet 111 between the second air duct plate 131 and the air guide plate 2. Since the air outlet end 22 of the air guide plate 2 is spaced apart from the first air duct plate 141, the actual air outlet area of ​​the air outlet 111 is narrower in the direction from the first air duct plate 141 to the second air duct plate 131 than the distance between the first air duct plate 141 and the second air duct plate 131. This reduces the actual air supply area of ​​the air outlet 111, thereby increasing the airflow pressure and the air supply distance, thus achieving long-distance air supply. In addition, since the air inlet end 21 of the air guide plate 2 abuts against the first air duct plate 141, all the airflow from the air outlet 111 flows out along the air guide plate 2, further reducing airflow loss and maximizing the airflow volume without changing the cooling and heating capacity, thus further increasing the air delivery distance of the air conditioner 100.

[0035] For example, such as Figure 2 As shown, the air outlet 111 of the air conditioner 100 is located at the lower end of the side wall of the housing 1. Along the airflow direction, the air outlet 11 is inclined downward, so that the airflow blows forward and downward. In the height direction of the air conditioner 100, the first air duct plate 141 is located below the second air guide plate 2.

[0036] In this embodiment of the invention, the air conditioner 100 can be an air handling device such as a wall-mounted air conditioner, a cabinet air conditioner, or a portable air conditioner 100.

[0037] According to an embodiment of the air conditioner 100, the air guide plate 2 is rotatably disposed at the air outlet 111 to open or close the air outlet 111. In the long-distance air supply state, the air conditioner 100 arranges at least a portion of the air guide plate 2 to be located within the air outlet duct 11, with the air inlet end 21 of the air guide plate 2 abutting against the first air duct plate 141, and the air outlet end 22 of the air guide plate 2 being spaced apart from both the first air duct plate 141 and the second air duct plate 131. This reduces the width of the actual air outlet area of ​​the air outlet 111 in the direction from the first air duct plate 141 to the second air duct plate 131 compared to the distance between the first air duct plate 141 and the second air duct plate 131, thereby reducing the actual air supply area of ​​the air outlet 111. This increases the airflow pressure and the air supply distance, thus achieving long-distance air supply. In addition, since the air inlet end 21 of the air guide plate 2 abuts against the first air duct plate 141, all the airflow from the air outlet 111 flows out along the air guide plate 2, further reducing airflow loss and maximizing the airflow volume without changing the cooling and heating capacity, thus further increasing the air delivery distance of the air conditioner 100.

[0038] In some embodiments of the present invention, such as Figure 2 As shown, in the long-distance air supply mode, the distance between the air outlet 22 of the air guide plate 2 and the second air duct plate 131 is less than the distance between the air inlet 21 of the air guide plate 2 and the second air duct plate 131. This arrangement of the air guide plate 2 ensures that the cross-sectional area of ​​the air outlet duct 11 at the air inlet 21 of the air guide plate 2 is larger than the cross-sectional area of ​​the air outlet duct 11 at the air outlet 22 of the air guide plate 2. This helps to increase the airflow velocity at the air outlet 111, thereby further increasing the air supply distance of the air conditioner 100.

[0039] In some embodiments of the present invention, such as Figure 2 As shown, in the long-distance air delivery mode, the distance between the air guide plate 2 and the second air duct plate 131 gradually decreases. It can be understood that as the distance between the air guide plate 2 and the second air duct plate 131 gradually decreases along the airflow direction, the cross-sectional area of ​​the air outlet 11 gradually decreases, which helps to increase the airflow velocity at the air outlet 111, further increasing the air delivery distance of the air conditioner 100. At the same time, this arrangement of the air guide plate 2 allows for smoother airflow, thereby further reducing the losses generated when the airflow flows along the air guide plate 2, thus ensuring the long-distance air delivery of the air conditioner 100.

[0040] In some embodiments of the present invention, such as Figure 2 As shown, in the long-distance air supply mode, the air guide plate 2 of the air conditioner 100 is formed as a curved plate concave towards the first air duct plate 141. This design makes the cross-sectional curve of the air guide plate 2 more closely match the airflow direction within the air outlet duct 11, preventing abrupt changes in the airflow field and airflow loss when the airflow passes through the air guide plate 2. This ensures that the airflow from the air conditioner 100 has a higher wind speed and a longer supply distance at the same rotational speed of the impeller 5, thereby improving air supply efficiency and ensuring long-distance air supply from the air conditioner 100. Simultaneously, this design ensures that the air inlet end 21 of the air guide plate 2 is higher than the air outlet end 22 of the air guide plate 2 in the height direction of the air conditioner 100, further increasing the supply distance of the airflow exiting the air outlet 111. Especially when the air conditioner 100 is in cooling mode, the air guide plate 2 can effectively raise the airflow after the cold air flows out, thereby increasing the air volume and the air delivery distance, so that the air conditioner 100 can cool down quickly and avoid the cold air blowing directly on the user, thus improving comfort.

[0041] At the same time, such as Figure 1As shown, when the air conditioner 100 is in the off state, the air guide plate 2 is in the initial position to close the air outlet 111. At this time, the air guide plate 2 is recessed towards the air outlet 11 to maintain the consistency of the appearance of the air conditioner 100. This setting can prevent the air guide plate 2 from being damaged by bumps, and when the air conditioner 100 is running, it can rotate to be recessed towards the first air duct plate 141 more quickly.

[0042] In some embodiments of the present invention, such as Figure 1 As shown, the housing 1 includes a volute 13 and a volute tongue 14. At least a portion of the volute tongue 14 is formed as a first air duct plate 141, and at least a portion of the volute 13 is formed as a second air duct plate 131. It is understood that the volute 13 and the volute tongue 14 further define an air outlet duct 11. By having at least a portion of the volute tongue 14 formed as the first air duct plate 141 and at least a portion of the volute 13 formed as the second air duct plate 131, the air conditioner 100 can achieve long-distance air delivery in conjunction with the air guide plate 2 without adding any other structures to the air conditioner 100.

[0043] Furthermore, such as Figure 1 As shown, the volute 14 also includes an arc-shaped segment 142 and a straight segment 143. One end of the straight segment 143 is connected to one end of the arc-shaped segment 142, and the other end of the arc-shaped segment 142 is connected to the first air duct plate 141. When the air conditioner 100 is in long-distance air delivery mode, the air inlet end 21 of the air guide plate 2 abuts against the first air duct plate 141 near the arc-shaped segment 142. Optionally, the first air duct plate 141, the arc-shaped segment 142, and the straight segment 143 are integrated into one piece, thereby increasing the overall strength of the volute 14. Furthermore, the impeller 5 can be located on the side of the arc-shaped segment 142 away from the air outlet 111, so that most of the fan is enclosed by the air outlet 11, further ensuring the air delivery distance of the air conditioner 100.

[0044] In some embodiments of the present invention, such as Figure 3 As shown, in the maximum air supply state, at least a portion of the air guide plate 2 is located within the air outlet duct 11. Both the air inlet end 21 and the air outlet end 22 of the air guide plate 2 are spaced apart from the first air duct plate 141 and the second air duct plate 131. It can be understood that when the air conditioner 100 is in the maximum air supply state, the air guide plate 2 is rotated until the air inlet end 21 of the air guide plate 2 is spaced apart from the first air duct plate 141 and the second air duct plate 131, and the air outlet end 22 of the air guide plate 2 is also spaced apart from the first air duct plate 141 and the second air duct plate 131. This allows the airflow within the air outlet duct 11 to be discharged between the air guide plate 2 and the first air duct plate 141 and between the air guide plate 2 and the second air duct plate 131. This arrangement allows the airflow within the air outlet duct 11 to be discharged to the maximum extent, thereby achieving the maximum air supply state of the air conditioner 100.

[0045] In some embodiments of the present invention, such as Figure 3As shown, when the air conditioner 100 is in its maximum air supply state, the distance between the air inlet end 21 of the air guide plate 2 and the first air duct plate 141 is less than the distance between the air inlet end 21 of the air guide plate 2 and the second air duct plate 131. It can be understood that the airflow rate discharged from the air outlet duct 11 via the space between the air guide plate 2 and the first air duct plate 141 is less than the airflow rate discharged via the space between the air guide plate 2 and the second air duct plate 131. This airflow diversion method better matches the airflow direction within the air outlet duct 11, making it less prone to abrupt changes in the airflow field that could cause aerodynamic losses, thereby improving air supply efficiency and enabling the air conditioner 100 to achieve maximum air supply.

[0046] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the air conditioner 100 also includes a motor 3. The motor 3 is located on the inner wall of the air outlet duct 11 and is directly connected to the air guide plate 2. It can be understood that by directly driving the air guide plate 2 to rotate via the motor 3, the air outlet 111 of the air guide plate 2 can be opened or closed. This driving method is relatively simple, involves relatively few parts, and has a stable structure. Therefore, the probability of failure is low, improving the performance of the air conditioner 100. At the same time, it is easy to manufacture and has high assembly efficiency.

[0047] When the first air duct plate 141 is located below the second air guide plate 2 in the height direction of the air conditioner 100, and the motor 3 is located on the first air duct plate 141, when the air conditioner 100 starts to run and turns on the long-distance air supply state, the motor 3 drives the air guide plate 2 to rotate counterclockwise until the air inlet end 21 of the air guide plate 2 stops at the first air duct plate 141. At this time, the air outlet end 22 of the air guide plate 2 is spaced apart from both the first air duct plate 141 and the second air duct plate 131. When the air conditioner 100 changes from the long-distance air supply state to the maximum range air supply state, the motor 3 drives the air guide plate 2 to rotate clockwise by a certain angle until both the air inlet end 21 and the air outlet end 22 of the air guide plate 2 are spaced apart from both the first air duct plate 141 and the second air duct plate 131.

[0048] In some embodiments of the present invention, a connecting arm is provided on one side of the air guide plate 2, and the motor 3 is directly connected to the connecting arm. The air guide plate 2 is rotated by the motor 3 driving the connecting arm to rotate. This driving method allows the motor 3 to better drive the air guide plate 2 to rotate, so as to meet the various air supply states of the air conditioner 100.

[0049] In some embodiments of the present invention, such as Figures 1-3 As shown, there is one motor 3. By driving the air guide plate 2 to rotate through one motor 3, the air guide plate 2 can be rotated to open or close the air outlet 111, and the air supply mode of the air conditioner 100 can be adjusted. Compared with multiple motors 3, the structure and program of the external control system are simpler, thereby improving the stability of the air conditioner 100.
