Description

Technical Field

[0001] This application relates to the field of air conditioning technology, for example to a single-fan vertical air conditioning indoor unit and an air conditioner. Background Technology

[0002] Air conditioners are common appliances used to improve the indoor environment for users. Their temperature regulation capabilities and air delivery methods are all related to the user's experience when using air conditioners.

[0003] With the increasing popularity of air conditioners, users are not only concerned about the speed of heating and cooling, but also about the comfort of air conditioning during air delivery. Among these, floor-standing air conditioner indoor units include single-outlet and multi-outlet models. For multi-outlet models, multiple air outlets can be vertically arranged at the same height to deliver air to both sides; alternatively, multiple air outlets can be located at the top or bottom of the casing to achieve different air delivery heights.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0005] For vertical air conditioner indoor units with top and bottom air outlets, different fans are usually required to deliver air to the top and bottom air outlets respectively. This multiple-fan design results in the fans occupying a large amount of internal space within the air conditioner indoor unit casing, making it difficult to achieve miniaturization of the vertical air conditioner indoor unit.

[0006] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0012] In some alternative embodiments, 25°≤A12≤60°.

[0013] In some optional embodiments, the arc-shaped air duct section further includes a lower air duct section located at the bottom. The lower air duct section includes a first lower air duct end connected to the heat exchange air duct and a second lower air duct end connected to the first air outlet. The angle between the third external tangent line of the first lower air duct end and the third horizontal line is A21, and the angle between the fourth external tangent line of the second lower air duct end and the fourth horizontal line is A22. The angle between the external tangent line of the lower air duct section and the horizontal line gradually decreases from the first lower air duct end to the second lower air duct end; and / or, A21 > A22; and / or, 15° ≤ A22 ≤ 75°.

[0014] In some alternative embodiments, 25°≤A22≤60°.

[0015] In some alternative embodiments, A22 > A12.

[0016] In some optional embodiments, the distance between the first upper air duct end and the first lower air duct end is L1, the distance between the second upper air duct end and the second lower air duct end is L2, and the air outlet height of the first air outlet is L3, wherein 1.1≤L1 / L2≤3; and / or 1.1≤L3 / L2≤2.8.

The air outlet height of the first air outlet duct is H1, and the air outlet height of the second air outlet duct is H2, with 0.15 ≤ H1 / H2 ≤ 1.

[0021] As can be seen, the single-fan vertical air conditioner indoor unit provided in this embodiment uses one fan to simultaneously supply air to the first and second air outlets located at different heights, simplifying the height of the vertical air conditioner indoor unit and facilitating miniaturization. Furthermore, the ratio between the air outlet height of the first air outlet duct and the air outlet height of the second air outlet duct is 0.15-1, which makes the air volume distribution between the first and second air outlets more reasonable and improves the air supply effect.

[0049] This disclosure provides a single-fan vertical air conditioner indoor unit, such as... Figures 1 to 11 As shown.

[0050] Optionally, the indoor unit of a single-fan vertical air conditioner includes a housing 1, a fan 2, a first air outlet 11, a second air outlet 12, a first air outlet duct 31, and a second air outlet duct 32. A heat exchange duct is formed within the housing 1; the fan 2 is disposed within the heat exchange duct; the first air outlet 11 is disposed within the housing 1; the second air outlet 12 is disposed within the housing 1, and is located below the first air outlet 11; the first air outlet duct 31 is disposed between the air outlet side 52 of the heat exchange duct and the first air outlet 11; the second air outlet duct 32 is disposed between the air outlet side 52 of the heat exchange duct and the second air outlet 12. The air outlet height of the first air outlet duct 31 is H1, the air outlet height of the second air outlet duct 32 is H2, and 0.15 ≤ H1 / H2 ≤ 1.

[0051] The casing 1 of the indoor unit of the air conditioner forms a heat exchange duct. A heat exchanger 4 and a fan 2 are installed within the heat exchange duct. Refrigerant flows within the heat exchanger 4. The casing 1 also has an air inlet and an air outlet connected to the heat exchange duct. Optionally, the air inlet is located at the rear of the casing 1, and the air outlet is located at the front or side of the casing 1. Room temperature air from the user's room enters the heat exchange duct through the air inlet. After heat exchange by the heat exchanger 4, the fan 2 delivers the cooled or heated air from the air outlet, thus achieving the cooling or heating effect on the user's indoor environment.

[0052] Optionally, the opening height of the air inlet is the same as the opening height of the air outlet; and / or, the opening height of the air inlet is the same as the height of the heat exchanger 4.

[0053] Optionally, an air inlet grille is provided at the air inlet, and a filter screen is provided on the inner side of the air inlet grille to block dust at the air inlet. Optionally, the filter screen is detachably installed at the air inlet to facilitate cleaning.

[0054] The vertical air conditioner indoor unit provided in this embodiment has only one fan 2 installed in its heat exchange duct. This fan 2 can supply air to the first air outlet 11 and the second air outlet 12, which are located at different heights. Optionally, the fan 2 is a vertically arranged cross-flow fan, such as... Figure 2 As shown.

[0055] Optionally, an air inlet is provided at the rear end of the housing 1, a first air outlet 11 is provided at the front end of the housing 1 and located at the upper part of the housing 1, and a second air outlet 12 is provided at the side of the housing 1 and located below the first air outlet 11. A heat exchange duct connects the air inlet to the first air outlet 11 and the second air outlet 12.

[0056] The heat exchange duct includes an inlet-side heat exchange duct and an outlet-side heat exchange duct. The inlet-side 51 of the heat exchange duct is the section between the air inlet and the fan 2, and the outlet-side 52 is the section between the fan 2 and the outlet duct. The outlet-side 52 of the heat exchange duct is connected to the first outlet duct 31 and the second outlet duct 32, so that the air in the heat exchange duct passes through the first outlet duct 31 and the second outlet duct 32 and is then discharged from the first outlet 11 and the second outlet 12, respectively. Figure 11 As shown.

[0057] Optionally, the second air outlet 12 can be a side air outlet, including a first side air outlet 121 and a second side air outlet 122. The first side air outlet 121 and the second side air outlet 122 are at the same height and are both located below the first air outlet 11.

[0058] Optionally, the air outlet height of the first air outlet duct 31 is H1, the air outlet height of the second air outlet duct 32 is H2, and 0.15≤H1 / H2≤1.

[0059] The ratio between the air outlet height of the first air outlet duct 31 and the air outlet height of the second air outlet duct 32 can be 0.15, 0.3, 0.5, or 1, etc. This increases the difference in air volume between the first air outlet 11 and the second air outlet 12, allowing the user to selectively open either the first air outlet 11 or the second air outlet 12 according to their requirements for air volume and height. Optionally, 0.15 ≤ H1 / H2 ≤ 0.5.

[0060] Optionally, when the air outlet heights at different locations of the first air outlet duct 31 are different, the air outlet height of the air outlet side 52 of the first air outlet duct 31 near the heat exchange duct is taken as its air outlet height; similarly, when the air outlet heights at different locations of the second air outlet duct 32 are different, the air outlet height of the air outlet side 52 of the second air outlet duct 32 near the heat exchange duct is taken as its air outlet height.

[0061] Optionally, the cross-flow fan 2 includes a cross-flow impeller, which includes a first impeller segment corresponding to the first air outlet 11 and a second impeller segment corresponding to the second air outlet 12. The first impeller segment is set at the same height as the first air outlet duct 31, and the second impeller segment is set at the same height as the second air outlet duct 32. Optionally, the diameter D1 of the first impeller segment is larger than the diameter D2 of the second impeller segment. Thus, when 0.15 ≤ H1 / H2 ≤ 0.5, i.e., under the premise that the air outlet height of the first air outlet duct 31 is relatively small, increasing the diameter D1 of the first impeller segment increases the airflow of the first air outlet 11. Optionally, the diameter of the first impeller segment is D1, such as... Figure 7 As shown, the diameter of the second impeller segment is D2, as... Figure 8 As shown, where 1 < D1 / D2 ≤ 1.5.

[0062] Optionally, the heat exchanger 4 includes a first heat exchange section corresponding to the first air outlet 11 and a second heat exchange section corresponding to the second air outlet 12 in the height direction. The heat exchange height of the first heat exchange section is the same as the air outlet height of the first air outlet duct 31, and the heat exchange height of the second heat exchange section is the same as the air outlet height of the second air outlet duct 32. Furthermore, the first heat exchange section and the second heat exchange section are connected in parallel. When only the first air outlet 11 needs to be opened, the first heat exchange section of the heat exchanger 4 can be opened, and the second heat exchange section can be closed, thus improving the air delivery effect of the first air outlet 11 alone. Alternatively, when only the second air outlet 12 needs to be opened, the second heat exchange section of the heat exchanger 4 can be opened, and the first heat exchange section can be closed, thus improving the air delivery effect of the second air outlet 12 alone.

[0063] Optionally, the first air outlet duct 31 and the second air outlet duct 32 are separated by an air outlet partition.

[0064] Optionally, the first air outlet duct 31 includes an arc-shaped duct section, which includes an upper air duct section 311 located at the top. The upper air duct section 311 includes a first upper air duct end 3111 connected to the heat exchange duct, and a second upper air duct end 3112 connected to the first air outlet 11. The angle between the first external tangent of the first upper air duct end 3111 and the first horizontal line is A11, and the angle between the second external tangent of the second upper air duct end 3112 and the second horizontal line is A12. The angle between the external tangent of the upper air duct section 3111 and the horizontal line gradually decreases from the first upper air duct end 3111 to the second upper air duct end 3112; and / or, A11 > A12; and / or, 15° ≤ A12 ≤ 75°.

[0065] The first air outlet duct 31 is provided with an arc-shaped duct section, which can concentrate the airflow, thereby increasing the air delivery distance of the first air outlet 11 and realizing long-distance air delivery from the first air outlet 11.

[0066] Optionally, the upper section 311 at the end of the curved air duct is convex.

[0067] Optionally, the external tangent at a specific point of the upwind section 311 forms an angle with the horizontal line at that point, and the angle gradually decreases from the first upwind end 3111 to the second upwind end 3112. This improves the air guiding effect of the upwind section 311 at the curved end of the duct.

[0068] The first upper air duct end 3111 is the end of the upper air duct section 311 that connects to the heat exchange air duct, or the first upper air duct end 3111 can also be understood as the starting end of the upper air duct section 3111, and the second upper air duct end 3112 is the ending end of the upper air duct section 3111. The angle between the first external tangent line of the first upper air duct end 3111 and the first horizontal line is A11, and the angle between the second external tangent line of the second upper air duct end 3112 and the second horizontal line is A12, where A11 > A12. Optionally, 15° ≤ A12 ≤ 75°. Figure 5 As shown.

[0069] Optionally, as one embodiment, A11 of the upwind section 311 is 50° and A12 is 30°; or, as another embodiment, A11 of the upwind section 311 is 45° and A12 is 25°.

[0070] Optionally, the angle difference between A11 and A12 is 10° to 25°, so that the angle change at both ends of the upwind section 311 is not too large, thereby improving the wind guiding effect of the upwind section 311.

[0071] Alternatively, 25°≤A12≤60°; or 25°≤A12≤45°.

[0072] Optionally, the arc-shaped air duct section further includes a lower air duct section 312 located at the bottom. The lower air duct section 312 includes a first lower air duct end 3121 connected to the heat exchange air duct, and a second lower air duct end 3122 connected to the first air outlet 11. The angle between the third external tangent line of the first lower air duct end 3121 and the third horizontal line is A21, and the angle between the fourth external tangent line of the second lower air duct end 3122 and the fourth horizontal line is A22. The angle between the external tangent line of the lower air duct section 3122 and the horizontal line gradually decreases from the first lower air duct end 3121 to the second lower air duct end 3122; and / or, A21 > A22; and / or, 15° ≤ A22 ≤ 75°.

[0073] Optionally, the downwind section 312 at the end of the arc-shaped air duct is convex arc-shaped.

[0074] Optionally, the external tangent at a specific point of the downwind duct section 312 forms an angle with the horizontal line at that point, and the angle gradually decreases from the first downwind duct end 3121 to the second downwind duct end 3122. This improves the air guiding effect of the downwind duct section 312 at the curved duct end.

[0075] The first downdraft end 3121 is the end of the downdraft section 312 that connects to the heat exchange duct; alternatively, the first downdraft end 3121 can also be understood as the starting end of the downdraft section 312, and the second downdraft end 3122 is the ending end of the downdraft section 312. The angle between the third external tangent line of the first downdraft end 3121 and the third horizontal line is A21, and the angle between the fourth external tangent line of the second downdraft end 3122 and the fourth horizontal line is A22, where A21 > A22. Optionally, 15° ≤ A22 ≤ 75°. Figure 5 As shown.

[0076] Optionally, as one embodiment, A21 of the downwind duct section 312 is 50° and A22 is 30°; or, as another embodiment, A21 of the downwind duct section 312 is 45° and A22 is 25°.

[0077] Optionally, the angle difference between A21 and A22 is 10° to 25°, so that the angle change at both ends of the downwind section 312 is not too large, thereby improving the air guiding effect of the downwind section 312.

[0078] Alternatively, 25°≤A22≤60°; or 25°≤A22≤45°.

[0079] Optionally, A22 > A12, and the distance between the first upper air duct end 3111 and the second upper air duct end 3112 is L5, and the distance between the first lower air duct end 3121 and the second lower air duct end 3122 is L6, where L5 > L6. This results in the air outlet 11 discharging slightly downwards. Figure 8 As shown.

[0080] Optionally, A22 < A12, and the distance between the first upper air duct end 3111 and the second upper air duct end 3112 is L5, and the distance between the first lower air duct end 3121 and the second lower air duct end 3122 is L6, where L5 < L6. This results in the air outlet 11 discharging slightly upwards. Figure 9 As shown.

[0081] Alternatively, L5 ≤ 1 / 3L1, and similarly, L6 ≤ 1 / 3L1.

[0082] Optionally, the distance between the first upper air duct end 3111 and the first lower air duct end 3121 is L1, the distance between the second upper air duct end 3112 and the second lower air duct end 3122 is L2, and the air outlet height of the first air outlet 11 is L3. Optionally, the distance L1 between the first upper air duct end 3111 and the first lower air duct end 3121 is equal to the air outlet height H1 of the first air outlet duct 31.

[0083] Optionally, 1.1 ≤ L1 / L2 ≤ 3. The ratio between L1 and L2 can be 1.1, 1.3, 1.5, 1.8, or 2, etc., so that the distance between the second upper air duct end 3112 and the second lower air duct end 3122 is not reduced too much, thus improving the air outlet effect of the first air outlet 11. Optionally, 1.1 ≤ L1 / L2 ≤ 2.

[0084] Optionally, 1.1 ≤ L3 / L2 ≤ 2.8. For example... Figure 1 As shown, the first air outlet 11 is an air outlet frame structure protruding from the housing 1. The highest point of the air outlet frame is slightly higher than the second upper air duct end 3112, and the lowest point of the air outlet frame is slightly lower than the second lower air duct end 3122. Figure 6 As shown. This improves the airflow efficiency of the first air outlet 11. Optionally, the first air outlet 11 may be equipped with an air outlet grille.

[0085] Optionally, 1.1≤L3 / L2≤2. For example, the ratio between L3 and L2 can be 1.1, 1.3, 1.5, 1.8 or 2, so that the air outlet frame of the first air outlet 11 does not reduce the air outlet speed of the first air outlet 11.

[0086] Optionally, L1 > L3.

[0087] Optionally, L1:L2:L3 = (1.1-3):1:(1.1-2.8).

[0088] Alternatively, L1:L2:L3 = (1.1-2):1:(1.1-2).

[0089] Optionally, the horizontal distance between the first upwind end 3111 and the first downwind end 3121 is L4, or the horizontal distance between the first downwind end 3121 and the second downwind end 3122 is L4. 0.3≤L4 / L2≤0.8.

[0090] This disclosure also provides an air conditioner, including the single-fan vertical air conditioner indoor unit as described above.

[0091] Optionally, the air conditioner may also include an outdoor unit.

[0092] An air conditioner consists of a refrigerant circulation system comprised of major structural components such as a compressor, a four-way valve, an outdoor heat exchanger, a throttling valve, and an indoor heat exchanger. Cooling, heating, dehumidification, and indoor heat exchanger self-cleaning modes can be achieved by controlling the compressor's operating frequency, the four-way valve's connection, and the fan's operating speed.
