Description

Technical Field

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

[0002] 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 flow conversion. In order to meet the needs of users in the whole house or a larger area, existing air conditioners or indoor air conditioners can only achieve this by increasing the air supply intensity of cold air or hot air. That is, since the wind source of existing air conditioners or indoor air conditioners is a single heat exchange air, long-distance air supply can only be achieved by increasing the wind force of the heat exchange air. However, with the increase in the wind force of the heat exchange air, the wind force felt by users indoors becomes more obvious, and even in some areas, users are directly blown by the heat exchange air, which causes the user's comfort experience to deteriorate, which is not conducive to the user's personal health and the promotion and sales of the product.

[0038] Figure 1 is a schematic cross-sectional view of an air conditioner indoor unit according to an embodiment of the utility model, such as Figure 1 As shown, and refer to Figures 2 to 5 The embodiment of the utility model provides an indoor unit of an air conditioner, comprising a housing 100, a crossflow fan wheel 200 and an axial flow fan wheel 300. The housing 100 at least partially forms a crossflow outlet 220 and an axial flow outlet 320 that are open forward, a crossflow air duct 210 connected to the rear side of the crossflow outlet 220, an axial flow air duct 310 connected to the rear side of the axial flow outlet 320, an upper axial flow air inlet 330 connected to the upper side of the axial flow air duct 310, and a lower axial flow air inlet 340 connected to the lower side of the axial flow air duct 310.

[0039] The crossflow outlet 220 and the axial flow outlet 320 are spaced apart and adjacent in the horizontal direction, the crossflow duct 210 and the axial flow duct 310 are at least partially spaced apart, and the upper axial flow inlet 330 and the lower axial flow inlet 340 are both spaced apart from the crossflow duct 210 in the horizontal direction. The crossflow impeller 200 is vertically arranged in the crossflow duct 210. The axial flow impeller 300 is horizontally arranged in the axial flow duct 310.

[0040] In this embodiment, the indoor wind can enter the axial flow air duct 310 from the upper axial flow air inlet 330 or the lower axial flow air inlet 340, and then be blown out from the axial flow air outlet 320 by the axial flow wind wheel 300. The axial flow wind blown out from the axial flow air outlet 320 is mixed with the cross flow wind blown out from the cross flow air outlet 220 at the front side of the casing 100. Take the cross flow air duct 210 as an example of a heat exchange air duct, that is, the cross flow wind blown out of the cross flow air outlet 220 is the heat exchange air. The temperature of the mixed wind formed by the mixing of the heat exchange air and the indoor wind is closer to the indoor wind. Even when the wind force of the heat exchange air is large, it can also avoid the cool wind or hot wind blowing directly to the user, thereby improving the user's comfort and preventing the user from being physically uncomfortable due to the direct blowing of the heat exchange air. This improves the user experience, achieves the purpose of improving the user experience, and makes the indoor unit of the air conditioner easy to promote and sell.

[0041] In some embodiments of the present invention, Figure 2 As shown, a first damper mechanism 410 is disposed in the axial air duct 310 , and the first damper mechanism 410 is at least configured to cut off or connect at least one of the upper axial air inlet 330 and the lower axial air inlet 340 .

[0042] In this embodiment, the first damper mechanism 410 can be arranged in the axial flow duct 310 near one end of the upper axial flow inlet 330, and at this time, the first damper mechanism 410 controls the upper axial flow inlet 330 and the axial flow duct 310 portion on the lower side of the first damper mechanism 410 to be cut off or connected. That is, the upper axial flow inlet 330 and the axial flow outlet 320 are controlled to be cut off or connected. The first damper mechanism 410 can also be arranged in the axial flow duct 310 near one end of the lower axial flow inlet 340, and at this time, the first damper mechanism 410 controls the lower axial flow inlet 340 and the axial flow duct 310 portion on the upper side of the first damper mechanism 410 to be cut off or connected. That is, the lower axial flow inlet 340 and the axial flow outlet 320 are controlled to be cut off or connected. That is to say, the switch of the upper axial air inlet 330 or the lower axial air inlet 340 can be controlled by the position of the first air door mechanism 410, and the air intake amount entering the axial air duct 310 from the upper axial air inlet 330 or the lower axial air inlet 340 can be adjusted to meet the user's diverse blowing needs.

[0043] In some embodiments of the present invention, Figure 1 As shown, a second damper mechanism 420 is disposed on at least one of the upper axial air inlet 330 and the lower axial air inlet 340 , and the second damper mechanism 420 is at least configured to control the opening and closing of at least one of the upper axial air inlet 330 and the lower axial air inlet 340 .

[0044] In this embodiment, the second damper mechanism 420 can be arranged at the upper axial air inlet 330 or at the lower axial air inlet 340. The opening and closing of the upper axial air inlet 330 or the lower axial air inlet 340 is directly controlled by the position of the second damper mechanism 420, thereby adjusting the air intake amount entering the axial air duct 310 from the upper axial air inlet 330 or the lower axial air inlet 340 to meet the diverse blowing needs of users.

[0045] In some embodiments of the present invention, Figure 1 As shown, in the case where the second damper mechanism 420 is provided at least at the upper axial air inlet 330, the upper axial air inlet 330 is located at the top of the housing 100. The second damper mechanism 420 includes a first air guide plate 421, and the front side of the first air guide plate 421 is rotatably connected to the housing 100 to close the upper axial air inlet 330 when the rear side of the first air guide plate 421 falls. Alternatively, when the rear side of the first air guide plate 421 is turned up, the upper axial air inlet 330 is opened.

[0046] In this embodiment, the rear side of the first air guide plate 421 is turned up, so that the axial air duct 310 is connected to the room through the upper axial air inlet 330. The indoor air enters the axial air duct 310 from the upper axial air inlet 330 and is blown out from the axial air outlet 320. When the upper axial air inlet 330 is not needed to enter the air, the rear side of the first air guide plate 421 falls down, so that the upper axial air inlet 330 is closed, avoiding the entry of dust and debris, and thus preventing the air conditioner from affecting normal operation due to dust and debris entering the interior.

[0047] Furthermore, when the rear side of the first air guide plate 421 is turned upward, a certain partition is formed between the upper axial flow air inlet 330 and the cross-flow air outlet 220, reducing or avoiding the short circuit between the air outlet and the air inlet. In particular, when the cross-flow air outlet 220 blows out hot air, the first air guide plate 421 can effectively block the rising hot air flow from directly flowing back into the upper axial flow air inlet 330. Moreover, the indoor air entering the axial flow air duct 310 is blown out from the front end of the housing 100, and the first air guide plate 421 guides the indoor air that needs to enter the axial flow air duct 310, which is more conducive to the circulation of the indoor air.

[0048] In some other embodiments of the present invention, the rear side of the first air guide plate 421 may be rotatably connected to the housing 100 .

[0049] In some other embodiments of the present invention, the first air guide plate 421 may also be slidably connected to the housing 100 .

[0050] In some embodiments of the present invention, Figure 1 As shown, the first air guide plate 421 can be rotatably connected to the housing 100 via a rotating shaft.

[0051] In this embodiment, the structure of the rotating shaft is simple and easy to process. Moreover, the first air guide plate 421 is rotatably connected to the housing 100 via the rotating shaft, which facilitates the installation and maintenance of the first air guide plate 421 and reduces the manufacturing and maintenance costs.

[0052] In some embodiments of the present invention, the upper axial air inlet 330 may be a rectangle extending in the transverse direction.

[0053] In this embodiment, the upper axial flow air inlet 330 extends in the lateral direction to reduce the resistance to wind, which is beneficial for the indoor wind to flow into the upper axial flow air inlet 330 .

[0054] Of course, in other embodiments of the present invention, the upper axial air inlet 330 may also be in other shapes such as a circle or a polygon.

[0055] In some embodiments of the present invention, Figure 2 As shown, an air inlet grille is provided at the upper axial air inlet 330 .

[0056] In this embodiment, the surrounding air is under negative pressure when the upper axial air inlet 330 takes in air. An air inlet grille is provided at the upper axial air inlet 330 to effectively prevent insects or other debris from being sucked in, thereby preventing the debris from affecting the normal use of the air conditioner.

[0057] In some embodiments of the present invention, Figure 1 As shown, in the case where the damper mechanism is provided at least at the lower axial air inlet 340, the lower axial air inlet 340 is located in the housing 100. The second damper mechanism 420 includes a second air guide plate 422, which is connected to the housing 100 by rotation around an axis passing through the middle of the second air guide plate 422, so as to enable the second air guide plate 422 to control the opening and closing of the lower axial air inlet 340 by flipping around the middle.

[0058] In this embodiment, when the second air guide plate 422 is rotated to a horizontal position, the lower axial air inlet 340 is closed, so that no air can enter the lower axial air inlet 340. When the second air guide plate 422 is rotated to a non-horizontal position, the lower axial air inlet 340 is connected to the axial air duct 310, so that air can enter the lower axial air inlet 340. Moreover, when the second air guide plate 422 rotates, the passable size of the axial air duct 310 can also be changed according to the rotation of the second air guide plate 422. By changing the passable size of the axial air duct 310, the air volume and wind speed blown out of the axial air outlet 320 are changed.

[0059] In some embodiments of the present invention, Figure 1 or Figure 2As shown, the air conditioner further includes a fresh air passage 520 connected to the outside, and the lower axial air inlet 340 is connected to the fresh air passage 520. A fresh air device 510 is arranged in the fresh air passage 520 to further filter the air.

[0060] Furthermore, the fresh air passage 520 is in communication with the axial flow air passage 310 .

[0061] In this embodiment, when outdoor fresh air enters the fresh air passage 520, it first passes through the fresh air device 510, then enters the axial flow air passage 310 through the lower axial flow air inlet 340, and is then blown out from the axial flow air outlet 320. The airflow from the fresh air passage into the axial flow air passage 310 is fresh air, which improves the indoor air quality after being blown into the room, which is beneficial to the health of the user.

[0062] Of course, in other embodiments of the present invention, the fresh air channel 520 may be a part of the axial flow air channel 310 .

[0063] In some other embodiments of the present invention, the air conditioner further comprises a filter channel, and the lower axial air inlet 340 is connected to the filter channel. A filter device is provided in the filter channel to filter the airflow, which is beneficial to the health of the user.

[0064] In some embodiments of the present invention, Figure 1 and Figure 4 As shown, there are two cross-flow air outlets 220, and the two cross-flow air outlets 220 are respectively located on the left and right sides of the axial flow air outlet 320. The two cross-flow air outlets 220 each correspond to a cross-flow air duct 210, and the two cross-flow air ducts 210 are spaced apart from each other in the horizontal direction and gradually close from front to back, so as to define the axial flow air duct 310 between the relatively separated parts of the two cross-flow air ducts 210. In addition, the upper axial flow air inlet 330 is located on the upper side of the cross-flow air duct 210, and / or the lower axial flow air inlet 340 is located on the lower side of the cross-flow air duct 210.

[0065] In this embodiment, since the upper axial air inlet 330 is located on the upper side of the cross-flow air duct 210 and the lower axial air inlet 340 is located on the lower side of the cross-flow air duct 210, the interference between the axial flow air duct 310 and the cross-flow air duct 210 is reduced, and the components within the axial flow air duct 310 and the cross-flow air duct 210 can be made more compact, thereby making the arrangement within the casing 100 more compact and saving space inside the casing 100.

[0066] In some embodiments of the present invention, Figure 3 As shown, the axial air outlet 320 is circular.

[0067] In this embodiment, the circular axial flow air outlet 320 matches the axial flow wind wheel 300, and the axial flow wind blown out through the axial flow wind wheel 300 is spiral-shaped. The circular axial flow air outlet 320 has a small and uniform resistance to the airflow during the flow of the axial flow wind, so that the blown axial flow wind is relatively uniform.

[0068] Of course, in other embodiments of the present invention, the axial air outlet 320 may also be in other shapes such as a rectangle or a triangle.

[0069] In some embodiments of the present invention, Figure 3 As shown, an air outlet grille is provided at the axial air outlet 320 .

[0070] In this embodiment, the axial flow fan wheel 300 is arranged at the axial flow air outlet 320, which is dangerous. The air outlet grille can protect the user. Moreover, the air outlet grille arranged at the axial flow air outlet 320 can also block dust and debris to ensure the life of the air conditioner.

[0071] In some other embodiments of the present invention, a swing blade is provided at the axial flow air outlet 320. The swing blade guides the air blown out of the axial flow air outlet 320 to meet the diverse blowing needs of the user.

[0072] In some embodiments of the utility model, the swing blades can be arranged vertically to guide the air left and right. A vertical air guide plate is arranged at the crossflow air outlet 220. The vertical swing blades cooperate with the vertical air guide plate to fully mix the normal temperature air and the heat exchange air, thereby improving the user's comfort. Moreover, each set of swing blades and air guide plates can be controlled separately to adjust the air outlet angle required by the user, thereby meeting the user's diverse blowing needs.

[0073] In other embodiments of the present invention, the swing blades may also be arranged horizontally to guide the wind upward and downward.

[0074] Alternatively, a horizontal air guide plate is provided at the cross-flow air outlet 220 .

[0075] In some embodiments of the present invention, the arrangement directions of the swing blades and the air guide plates, that is, the air guide directions, can be arbitrarily selected.

[0076] In some embodiments of the present invention, the cross-flow air duct 210 and the axial-flow air duct 310 are arranged at intervals.

[0077] In this embodiment, since the axial flow duct 310 and the cross flow duct 210 are independent of each other, the axial flow outlet 320 and the cross flow outlet 220 can both discharge air independently. Both the cross flow outlet 220 and the axial flow outlet 320 can discharge air in different directions to meet the diverse blowing needs of users.

[0078] In some embodiments of the present invention, Figure 5 As shown, the cross-flow air duct 210 and the axial flow air duct 310 are partially connected to form a heat exchange axial flow air inlet 350 connected between the cross-flow air duct 210 and the axial flow air duct 310 in the housing 100 .

[0079] In this embodiment, taking the case where only the axial flow impeller 300 is working and the cross flow impeller 200 is not working as an example, the first air guide plate 421 and / or the second air guide plate 422 are opened, and the heat exchange air passing through the cross flow air duct 210 enters the axial flow air duct 310 from the heat exchange axial flow air inlet 350 and is mixed with the normal temperature air entering from the upper axial flow air inlet 330 and / or the lower axial flow air inlet 340, and then is blown out from the axial flow air outlet 320. At this time, the outlet air temperature of the indoor unit of the air conditioner is closer to the indoor temperature than the heat exchange air that is not mixed with the indoor air, so that the user feels more comfortable after being blown by the air.

[0080] The first air guide plate 421 and the second air guide plate 422 are closed, so that the upper axial air inlet 330 and the lower axial air inlet 340 are covered. Only the heat exchange air passing through the cross-flow air duct 210 enters the axial air duct 310 from the heat exchange axial air inlet 350 and then blows out from the axial air outlet 320. At this time, the air outlet temperature of the indoor unit of the air conditioner is the preset temperature of the user, which can quickly heat up or cool down the room to meet the user's diverse blowing needs.

[0081] Of course, in other embodiments of the present invention, only the crossflow impeller 200 may work, and the axial flow impeller 300 may not work. Alternatively, the crossflow impeller 200 and the axial flow impeller 300 may work simultaneously.

[0082] In some embodiments of the present invention, Figure 5 As shown, the heat exchange axial air inlet 350 is provided with a third air guide plate 430, and the front side or the rear side of the third air guide plate 430 is connected to the housing 100 by rotation around the vertical axis, so that when the third air guide plate 430 is turned into the axial air duct 310, the heat exchange axial air inlet 350 is opened. Alternatively, when the third air guide plate 430 falls back onto the air duct wall of the cross-flow air duct 210, the heat exchange axial air inlet 350 is closed.

[0083] In this embodiment, the third air guide plate 430 is opened, and the heat exchange air passing through the cross-flow air duct 210 enters the axial flow air duct 310 from the heat exchange axial flow air inlet 350, mixes with the normal temperature air entering from the upper axial flow air inlet 330 and / or the lower axial flow air inlet 340, and then blows out from the axial flow air outlet 320. At this time, the outlet air temperature of the indoor unit of the air conditioner is closer to the indoor temperature than the heat exchange air that is not mixed with the indoor air, so that the user feels more comfortable after being blown by the air.

[0084] The third air guide plate 430 is closed to cover the heat exchange axial air inlet 350. The axial air duct 310 and the cross flow air duct 210 are independent of each other, and the axial air outlet 320 and the cross flow air outlet 220 can both discharge air separately to meet the diverse blowing needs of users.

[0096] The fourth mode: open the second air guide plate 422 and the third air guide plate 430 at the same time, and close the first air guide plate 421. The fresh air enters the axial flow air duct 310 from the lower axial flow air inlet 340, and the heat exchange air enters the axial flow air duct 310 from the heat exchange axial flow air inlet 350. After the fresh air and the heat exchange air are mixed in the axial flow air duct 310, the axial flow wind wheel 300 blows the mixed air in the axial flow air duct 310 out of the axial flow air outlet 320, and mixes it with the air blown out from the cross-flow air outlet 220 on the outside of the casing 100, which is beneficial to the mixing of the fresh air, the duct mixed air and the heat exchange air on both sides.

The axial flow wind wheel 300 blows the mixed air in the axial flow air duct 310 out of the axial flow air outlet 320, and mixes it with the air blown out from the cross-flow air outlet 220 on the outside of the casing 100, which is beneficial to the mixing of the indoor air, the fresh air and the heat exchange air on both sides, and the mixing degree is better than that of the second mode.

After the indoor air, fresh air and heat exchange air are mixed in the axial flow air duct 310, the axial flow wind wheel 300 blows the mixed air in the axial flow air duct 310 out of the axial flow air outlet 320, and mixes it with the air blown out from the cross-flow air outlet 220 on the outside of the casing 100, which is beneficial to the mixing of the indoor air, fresh air, duct mixed air and the heat exchange air on both sides, and the mixing degree is the best.

[0099] The utility model also provides an air conditioner, comprising a compressor unit and an air conditioner indoor unit of any of the above embodiments. The compressor unit is arranged indoors or outdoors to perform heat exchange with the outdoor environment. The air conditioner indoor unit is connected to the compressor unit.

[0100] 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. Taking the crossflow air duct 210 as the heat exchange air duct as an example, the indoor air can enter the axial flow air duct 310 from the upper axial flow air inlet 330 or the lower axial flow air inlet 340, and then be blown out of the axial flow air duct 310 by the axial flow wind wheel 300 through the axial flow air outlet 320. The axial flow wind blown out from the axial flow air outlet 320 is mixed with the crossflow wind blown out from the crossflow air outlet 220 at the front side of the indoor unit of the air conditioner. Since the crossflow wind blown out of the crossflow air outlet 220 is heat exchange air, the heat exchange air and the indoor air are mixed so that the temperature of the mixed air is closer to the indoor air. Even when the wind force of the heat exchange air is large, the cool wind or hot wind can be avoided from blowing directly on the user, thereby improving the user's comfort and preventing the user from being physically uncomfortable due to the direct blowing of the heat exchange air. In this way, the user's experience is improved, the purpose of improving the user experience is achieved, and the indoor unit of the air conditioner is easy to promote and sell.
