Description

Technical Field

[0001] The utility model relates to the technical field of air treatment, in particular to a vertical air conditioner indoor unit and an air conditioner. Background Art

[0002] Vertical air conditioners or indoor air conditioners in indoor environments usually adjust indoor environmental factors such as indoor temperature, humidity, and air quality by means of commutation. In order to meet the needs of users in the whole house or a larger area, existing air conditioners or vertical air conditioners increase the air outlet area by adopting a cross-flow impeller to obtain a larger air volume. However, the increase in the air outlet area will bring about the problem that the wind pressure is not easy to increase, resulting in the fact that when long-distance air supply is to be achieved in the whole house or a larger area, the air can only be supplied with a stronger wind pressure, which will cause the wind feeling that users who are close to the air conditioner or vertical air conditioner can feel very obvious, and even the user is blown directly, thereby reducing the user's comfort.

[0016] Optionally, there are two heat exchange air outlets, each of which is connected to a heat exchange air duct, and in the horizontal direction, the two heat exchange air ducts gradually close from front to back, so that the relatively separated parts of the front sections of the two heat exchange air ducts define the axial flow air duct.

[0017] The air outlet side of the axial flow wind wheel faces forward and is centrally arranged in front of the axial flow air duct.

[0018] The distance between the air inlet side of the axial flow wind wheel and the joining point of the two heat exchange air ducts is smaller than the diameter of the axial flow wind wheel.

When the axial flow wind wheel is working, axial flow wind can be blown out from the axial flow air outlet, that is, the total air outlet area of ​​the vertical air conditioner indoor unit is increased, and the wind speed can be reduced when the air flow rate remains unchanged. That is, while meeting the user's demand for rapid air exchange in the whole house or a larger area, the wind speed can be reduced, thereby reducing the wind feeling that can be felt by users who are closer to the air conditioner or the vertical air conditioner.

Moreover, the axial flow wind blown out from a high place does not blow directly on the user, and it is not easy for the wind to fall on the user, which reduces the user's perception of wind and further improves the user experience.

Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0038] Figure 1 is a schematic cross-sectional view of a vertical air conditioner indoor unit according to an embodiment of the utility model, as shown in Figure 1 As shown, and refer to Figures 2 to 3 The embodiment of the utility model provides a vertical air conditioner indoor unit of an air conditioner, comprising a vertically arranged casing 100, a crossflow fan 200 arranged in a heat exchange air duct 210, and an axial flow fan 300 arranged in an axial flow air duct 310. A heat exchange air outlet 220 extending vertically is formed on the casing 100, and an axial flow air outlet 320 spaced apart from the heat exchange air outlet 220 in the horizontal direction. Among them, the axial flow air outlet 320 is at the top of the vertical shell wall of the casing 100. Moreover, in the vertical direction, the bottom of the axial flow air outlet 320 is flush with the middle of the heat exchange air outlet 220, or is above the middle of the heat exchange air outlet 220. Moreover, a heat exchange air duct 210 connected to the heat exchange air outlet 220, and an axial flow air duct 310 connected to the axial flow air outlet 320 are defined in the casing 100. The crossflow fan 200 is arranged vertically. In the horizontal direction, the wheel end surface of the axial flow wind wheel 300 is arranged opposite to the axial flow air outlet 320 .

[0039] In this embodiment, the axial flow wind wheel 300 can be used to blow out axial flow wind forward. Since the axial flow wind has a large wind outlet area, the axial flow wind is relatively gentle. The cross flow wind wheel 200 can be used to blow out cross flow wind. The wind speed of the cross flow wind blown out by the cross flow wind wheel 200 is relatively high, so that the cross flow wind can reach a longer distance.

[0040] In this embodiment, by simultaneously providing the axial air outlet 320 and the heat exchange air outlet 220, the total air outlet area of ​​the vertical air conditioner indoor unit is increased, and the wind speed can be reduced while the air flow rate remains unchanged. That is, while satisfying the user's demand for rapid air exchange in the whole house or a larger area, the wind speed can be reduced, thereby reducing the wind sensation felt by users who are closer to the air conditioner or the vertical air conditioner.

[0041] On the other hand, the axial flow outlet 320 is located at the upper part of the housing 100, which is at a higher position. The axial flow wind blown by the axial flow wind wheel 300 will be blown out from a higher position, so that the airflow can reach a farther distance, which is conducive to the rapid circulation of indoor air. Moreover, the axial flow wind blown out from a higher position does not blow directly on the user, and it is not easy for the strong wind to fall on the user, which reduces the user's feeling of wind and improves the user experience.

[0042] In some embodiments of the utility model, the axial flow wind wheel 300 can blow forward the axial flow wind of normal temperature, and the axial flow outlet 320 and the heat exchange outlet 220 have an overlapping part in the vertical direction, so that the normal temperature wind blown forward through the axial flow outlet 320 in the axial flow air duct 310 and the cross-flow heat exchange wind blown forward through the heat exchange outlet 220 in the heat exchange air duct 210 can be fully mixed at the front side of the housing 100, so that the mixed wind blown out is closer to the room temperature. Of course, the axial flow outlet 320 can also blow out the axial flow heat exchange wind.

[0043] In some embodiments of the present invention, on the vertical plane where the axial flow outlet 320 is located, the projection of the axial flow wind wheel 300 is located inside the axial flow outlet 320. In the vertical direction, the bottom of the axial flow wind wheel 300 is flush with the middle of the heat exchange outlet 220.

[0044] In this embodiment, the axial flow wind wheel 300 is arranged at a relatively high position, so that the axial flow wind can be blown to a farther position, and it is not easy for strong wind to fall on the user, thereby reducing the user's perception of wind and improving the user experience.

[0045] In other embodiments of the present invention, Figure 2 As shown, the bottom of the axial flow wind wheel 300 may also be located above the middle of the heat exchange air outlet 220 .

[0046] In some embodiments of the present invention, in the vertical direction, the top of the axial flow wind wheel 300 is flush with the top of the heat exchange air outlet 220 .

[0047] In this embodiment, the position of the axial flow wind wheel 300 is not higher than the heat exchange air outlet 220, so that the overlapping part of the axial flow air outlet 320 and the heat exchange air outlet 220 in the horizontal direction is large, and the hot air and the axial flow air can be fully mixed on the front side of the casing 100, thereby improving the user's comfort.

[0048] In other embodiments of the present invention, Figure 2 As shown, the top of the axial flow wind wheel 300 may also be below the top of the heat exchange air outlet 220 .

[0049] Preferably, if Figure 2 As shown, on the vertical plane where the axial flow outlet 320 is located, the projection of the axial flow wind wheel 300 is inside the axial flow outlet 320. Vertically, the bottom of the axial flow wind wheel 300 is above the middle of the heat exchange outlet 220. And the top of the axial flow wind wheel 300 is below the top of the heat exchange outlet 220.

[0050] In this embodiment, the projections of the axial flow wind wheel 300 in the vertical direction are all located on the projection of the heat exchange air outlet 220 in the vertical direction, so that the overlapping part of the axial flow air outlet 320 and the heat exchange air outlet 220 in the horizontal direction is large, and the hot air and the axial flow air can be fully mixed on the front side of the casing 100, so that the mixed air blown out is closer to the room temperature, thereby improving the user's comfort.

[0051] In some embodiments of the present invention, Figure 1 As shown, the diameter D2 of the axial flow wind wheel is greater than the diameter D1 of the cross flow wind wheel.

[0052] In this embodiment, the diameter D2 of the axial flow wind wheel is larger than the diameter D1 of the cross flow wind wheel, so that the axial flow wind blown out by the axial flow wind wheel 300 has a greater wind force than the heat exchange wind blown out by the cross flow fan. The axial flow wind and the heat exchange wind continue to flow forward after mixing, which speeds up the circulation of indoor airflow and improves the heat exchange efficiency of the air conditioner.

[0053] Furthermore, the diameter D1 of the crossflow impeller may be 94 mm to 100 mm.

[0054] In some embodiments of the present invention, preferably, when there are two heat exchange outlets 220, the diameter D2 of the axial flow wind wheel is greater than the diameter D1 of the cross flow wind wheel, and the diameter D2 of the axial flow wind wheel is equal to 1.6-2.1 times the diameter D1 of the cross flow wind wheel.

[0055] In this embodiment, the diameter D2 of the axial flow wind wheel is less than 1.6 times the diameter D1 of the cross flow wind wheel. The axial flow wind force blown out by the axial flow wind wheel 300 is too small to drive the heat exchange wind blown out by the cross flow wind wheel 200 to flow forward, thereby reducing the heat exchange efficiency of the air conditioner to the room. The diameter D2 of the axial flow wind wheel is greater than 2.1 times the diameter D1 of the cross flow wind wheel. The axial flow wind force blown out by the axial flow wind wheel 300 is too large, which reduces the user experience and is not conducive to the installation and manufacturing of the axial flow wind wheel 300. The diameter D2 of the axial flow wind wheel is equal to 1.6-2.1 times the diameter D1 of the cross flow wind wheel, so that the axial flow wind force blown out by the axial flow wind wheel 300 is greater than the heat exchange wind force blown out by the cross flow fan. The axial flow wind and the heat exchange wind are mixed and continue to flow forward, which accelerates the circulation of the indoor airflow and improves the heat exchange efficiency of the air conditioner.

[0056] Preferably, the diameter D1 of the crossflow impeller is 97.8 mm, and the diameter D2 of the axial flow impeller is 200 mm.

[0057] In other embodiments of the present invention, when there is one heat exchange outlet 220, the diameter D2 of the axial flow wind wheel is greater than the diameter D1 of the cross flow wind wheel, and the diameter D2 of the axial flow wind wheel is equal to 0.8-1.05 times the diameter D1 of the cross flow wind wheel.

[0058] In some embodiments of the present invention, the width L2 of the axial flow air outlet is greater than the diameter D2 of the axial flow wind wheel, and the difference is 10-12 mm.

[0059] In this embodiment, the width L2 of the axial flow outlet is 10-12 mm larger than the diameter D2 of the axial flow wind wheel, which is conducive to the installation of the axial flow wind wheel 300. In addition, the gap between the edge of the axial flow outlet 320 and the outer edge of the axial flow wind wheel 300 is small, which improves the space utilization of the housing 100.

[0060] Preferably, the width L2 of the axial flow outlet in this case is 210 mm.

[0061] In some embodiments of the present invention, Figure 1 As shown, the diameter D2 of the axial flow wind wheel is greater than the width L1 of the heat exchange outlet in the horizontal direction.

[0062] In this embodiment, the larger diameter D2 of the axial flow wind wheel can increase the air output of the axial flow outlet 320. After mixing with the heat exchange air blown out by the cross-flow fan, the mixed air can be pushed forward to continue to flow, thereby accelerating the circulation of indoor air flow and improving the heat exchange efficiency of the air conditioner, so that the air conditioner can meet the user's demand for rapid air exchange in the whole house or a larger area.

[0063] In some embodiments of the present invention, preferably, when there are two heat exchange outlets 220, the diameter D2 of the axial flow wind wheel is greater than the horizontal width L1 of the heat exchange outlet, and the diameter D2 of the axial flow wind wheel is equal to 2-2.5 times the horizontal width L1 of the heat exchange outlet.

[0064] In this embodiment, since there are two cross-flow air outlets, the diameter D2 of the axial flow wind wheel is larger than the horizontal width L1 of the heat exchange air outlet, and the sum of the horizontal widths L1 of the two heat exchange air outlets is close to the diameter D2 of the axial flow wind wheel, so that the cross-flow wind and the axial flow wind are mixed more fully.

[0065] Preferably, the width L1 of the heat exchange outlet in the horizontal direction is 82 mm.

[0066] In other embodiments of the present invention, when there is one heat exchange outlet 220, the diameter D2 of the axial flow wind wheel is greater than the horizontal width L1 of the heat exchange outlet, and the diameter D2 of the axial flow wind wheel may also be equal to 1-1.25 times the horizontal width L1 of the heat exchange outlet.

[0067] In some embodiments of the present invention, Figure 1 As shown, the thickness H1 of the axial flow wind wheel 300 is smaller than the diameter D2 of the axial flow wind wheel.

[0068] In this embodiment, the diameter D2 of the axial flow wind wheel is large, so that the wind output of the axial flow wind wheel 300 is large, and the thickness H1 of the axial flow wind wheel 300 is small, so that the axial flow wind wheel 300 is easy to install on the housing 100. Moreover, the thickness H1 of the axial flow wind wheel 300 is smaller than the diameter D2 of the axial flow wind wheel, and the shape is beautiful. Moreover, the small thickness H1 of the axial flow wind wheel 300 is easy to manufacture, thereby reducing the production cost.

[0069] In some embodiments of the present invention, the thickness H1 of the axial flow wind wheel 300 is smaller than the diameter D2 of the axial flow wind wheel, and the thickness H1 of the axial flow wind wheel 300 is equal to 0.25-0.35 times of the diameter D2 of the axial flow wind wheel.

[0070] In this embodiment, the thickness H1 of the axial flow wind wheel 300 is less than 0.25 times the diameter D2 of the axial flow wind wheel, so that the thickness H1 of the axial flow wind wheel 300 is relatively small and cannot blow out strong axial wind. The thickness H1 of the axial flow wind wheel 300 is greater than 0.35 times the diameter D2 of the axial flow wind wheel, and the thickness H1 of the axial flow wind wheel 300 is relatively too thick, occupying too much internal space of the housing 100, thereby increasing the manufacturing cost. The thickness H1 of the axial flow wind wheel 300 is equal to 0.25-0.35 times the diameter D2 of the axial flow wind wheel, so that the wind output force of the axial flow wind wheel 300 is relatively large, and because the thickness H1 of the axial flow wind wheel 300 is small, the axial flow wind wheel 300 is easy to install on the housing 100. Moreover, the shape of the axial flow wind wheel 300, which is smaller than the diameter D2 of the axial flow wind wheel, is beautiful. Furthermore, the small thickness H1 of the axial flow wind wheel 300 is easy to manufacture and reduces the production cost.

[0071] Preferably, the thickness H1 of the axial flow wind wheel 300 is 60 mm.

[0072] In some embodiments of the present invention, preferably, there are two heat exchange air outlets 220, such as Figure 1 As shown, the two heat exchange air outlets 220 are each connected to a heat exchange air duct 210 , and in the horizontal direction, the two heat exchange air ducts 210 gradually close from front to back, so that the relatively separated parts of the front sections of the two heat exchange air ducts 210 define an axial flow air duct 310 .

[0073] In this embodiment, since the two heat exchange air ducts 210 gradually close from front to back, the two heat exchange air ducts 210 can share a heat exchanger of the air conditioner, thereby reducing the number of components inside the casing 100, and further making the arrangement inside the casing 100 more compact, thereby saving space inside the casing 100.

[0074] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the air outlet side of the axial flow wind wheel 300 faces forward and is centrally arranged in front of the axial flow air duct 310. The distance a2 between the air inlet side of the axial flow wind wheel and the junction of the two heat exchange air ducts is smaller than the diameter D2 of the axial flow wind wheel.

[0075] In this embodiment, the distance a2 between the air inlet side of the axial flow fan wheel and the closing point of the two heat exchange air ducts is reduced without affecting the air flow rate, and the diameter D2 of the axial flow fan wheel is increased. The size of the axial flow air duct 310 is reduced, making the arrangement inside the housing 100 more compact, saving the space inside the housing 100, and the air volume of the axial flow air outlet 320 is not affected, thereby improving the heat exchange efficiency between the air conditioner and the room.

[0076] Preferably, in some embodiments of the present invention, the distance a2 between the air inlet side of the axial flow wind wheel and the joining point of the two heat exchange air ducts is equal to 0.5-0.7 times the diameter D2 of the axial flow wind wheel.

[0077] In this embodiment, when the distance a2 between the air inlet side of the axial flow wind wheel and the closing part of the two heat exchange air ducts is less than 0.5 times the diameter D2 of the axial flow wind wheel, the cross-sectional area of ​​the axial flow air duct 310 is small, and it is not easy for the airflow to flow in the axial flow air duct 310, which affects the flow rate of the airflow. When the distance a2 between the air inlet side of the axial flow wind wheel and the closing part of the two heat exchange air ducts is greater than 0.7 times the diameter D2 of the axial flow wind wheel, the diameter D2 of the axial flow wind wheel is too small, so that the air volume blown out by the axial flow outlet 320 is small, which reduces the heat exchange efficiency between the air conditioner and the room. Preferably, when the distance a2 between the air inlet side of the axial flow wind wheel and the closing part of the two heat exchange air ducts 210 is equal to 0.6 times the diameter D2 of the axial flow wind wheel, the distance a2 between the air inlet side of the axial flow wind wheel and the closing part of the two heat exchange air ducts is reduced without affecting the airflow rate, and the diameter D2 of the axial flow wind wheel is increased as much as possible. The size of the axial air duct 310 is reduced, making the arrangement inside the casing 100 more compact and saving the space inside the casing 100, while the air volume of the axial air outlet 320 is not affected, thereby improving the heat exchange efficiency between the air conditioner and the room.

[0078] Preferably, the distance a2 between the air inlet side of the axial flow wind wheel and the junction of the two heat exchange air ducts is 123 mm.

[0079] In some embodiments of the present invention, Figure 1 As shown, at least one heat exchange duct 210 is connected to the axial flow duct 310 via a vertically arranged first axial flow inlet 330, and in the front-to-back direction, the distance a1 between the first axial flow inlet and the axial flow wind wheel is greater than or equal to 0.18 times the diameter D2 of the axial flow wind wheel.

[0080] In this embodiment, when the distance a1 between the first axial air inlet and the axial wind wheel is less than 0.18 times the diameter D2 of the axial wind wheel, the distance between the first axial air inlet 330 and the axial wind wheel 300 is too close, so that the heat exchange air entering from the first axial air inlet 330 has no time to mix with the indoor air in the axial air duct 310 and is blown out by the axial wind wheel 300, so that the heat exchange air and the indoor air are not mixed sufficiently, which reduces the user experience. Preferably, the distance a1 between the first axial air inlet and the axial wind wheel is equal to 0.185 times the diameter D2 of the axial wind wheel.

[0081] Preferably, the distance a1 between the first axial flow air inlet and the axial flow wind wheel may be 37 mm.

[0082] In some embodiments of the present invention, Figure 3As shown, a second axial air inlet 340 connected to the axial air duct 310 is formed at the top of the housing 100. A third axial air inlet 350 connected to the axial air duct 310 is formed in the housing 100 and is located at the bottom of the axial air duct 310.

[0083] In this embodiment, since the upper axial air inlet is located on the upper side of the axial air duct 310 and the lower axial air inlet is located on the lower side of the axial air duct 310, the interference between the axial air duct 310 and the cross-flow air duct and other components is reduced, the components within the shell can be made more compact, and space inside the casing 100 is saved.

[0084] The utility model also provides an air conditioner, comprising a compressor unit and a vertical air conditioner indoor unit in any of the above embodiments. The compressor unit is arranged indoors or outdoors to perform heat exchange with the outdoor environment. The vertical air conditioner indoor unit is connected to the compressor unit.

[0085] In this embodiment, the compressor unit performs heat exchange with the outdoor environment so that the indoor unit of the air conditioner can blow out heat exchange air. The axial flow wind wheel 300 is used to blow the air flow in the axial flow air duct 310 forward through the axial flow air outlet 320. The crossflow wind wheel 200 is used to blow out the heat exchange air through the heat exchange air outlet 220. The axial flow air outlet 320 and the heat exchange air outlet 220 have overlapping parts in the horizontal direction, so that the heat exchange air and the axial flow air can be fully mixed at the front side of the housing 100, so that the mixed air blown out is closer to the room temperature. The axial flow wind wheel 300 can blow out strong wind or high-speed wind when working to meet the user's demand for rapid air exchange in the whole house or a larger area. Moreover, the axial flow air outlet 320 is located at the upper part of the housing 100, and the position is relatively high. The strong wind blown out by the axial flow wind wheel 300 will be blown out from a high place, which can make the air flow reach a farther distance, not blow directly to the user, and do not let the strong wind fall on the user, reducing the user's perception of the wind and improving the user experience. Moreover, the airflow blown out by the axial flow fan wheel 300 reaches a farther distance, which is beneficial to the rapid circulation of indoor air.
