[0046] Figure 1 FIG. 1 is a schematic partial structural diagram of an indoor unit of an air conditioner according to an embodiment of the present utility model. 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 110 and an air mixing fan. The housing 110 has a first air duct 142 and a second air duct 141, and an air mixing inlet 190 is arranged on the front wall of the housing 110, wherein the first air duct 142 and the second air duct 141 are arranged in sequence along the width direction of the housing 110, a first connecting port 1423 is arranged on the side wall of the first air duct 142 facing the second air duct 141, and a second connecting port 1413 is arranged on the side wall of the second air duct 141 facing the first air duct 142. The air mixing inlet 190 is arranged between the first air duct 142 and the second air duct 141. The air mixing fan is arranged in the housing 110 and between the first air duct 142 and the second air duct 141, and is configured to promote the airflow to enter the housing 110 from the air mixing inlet 190 and enter the first air duct 142 through the first connecting port 1423, and enter the second air duct 141 through the second connecting port 1413.

[0047] In the indoor unit of the air conditioner of the embodiment of the utility model, when the indoor unit of the air conditioner is working, the air mixing fan starts to work, and the indoor air is sucked into the housing 110 by the air mixing inlet 190. Then, under the action of the air mixing fan, a part of the indoor air enters the first air duct 142 through the first connecting port 1423, and the indoor air is mixed with the heat exchange air in the first air duct 142, and then blown out to the room. Another part of the indoor air enters the second air duct 141 through the second connecting port 1413, and the indoor air is mixed with the heat exchange air in the second air duct 141, and then blown out to the room. Since the wind blown out of the first air duct 142 and the second air duct 141 is a mixed wind of the heat exchange air and the indoor air, when the indoor unit of the air conditioner is in the cooling mode, the indoor air can neutralize the relatively strong cold wind, so that the wind blown out of the indoor unit of the air conditioner is cool but not cold. When the indoor unit of the air conditioner is in the heating mode, the indoor air can neutralize the relatively strong warm wind, so that the wind blown out of the indoor unit of the air conditioner is warm but not dry, thereby improving the user experience.

[0048] In some embodiments of the present invention, Figures 1 to 3 As shown, the indoor unit of the air conditioner further includes a first baffle 152. The first baffle 152 is movably disposed in the housing 110 and configured to close the first communication port 1423.

[0049] It can be seen from the above embodiment that the first communication port 1423 is connected to the first air duct 142, and the mixed air inlet 190 is connected to the first communication port 1423. In this embodiment, when the indoor unit of the air conditioner is working, the first baffle 152 is moved to close the first communication port 1423, so that the first air duct 142 is not connected to the mixed air inlet 190. At this time, the wind blown out of the first air duct 142 is relatively strong cold wind or warm wind, which meets the user's demand for rapid increase or decrease of indoor temperature, and further improves the user's use experience.

[0050] In some alternative embodiments of the present invention, Figures 1 to 3 As shown, the indoor unit of the air conditioner further includes a first baffle 152. The first baffle 152 is movably disposed in the housing 110 and configured to disconnect the first air duct 142 and open the first communication port 1423 so that only the first communication port 1423 is connected to the outlet of the first air duct 142.

[0051] As can be seen from the above embodiment, the first communication port 1423 is connected to the outlet of the first air duct 142, and the air mixing inlet 190 is connected to the first communication port 1423. In this embodiment, the first baffle 152 is movable to disconnect the first air duct 142, so that the first communication port 1423 is connected to the outlet of the first air duct 142. At this time, the indoor air enters the first air duct 142 through the first communication port 1423, and then blows out from the outlet of the first air duct 142, so that the outlet of the first air duct 142 blows out indoor air, so as to meet the diverse air supply needs of users.

[0052] In some alternative embodiments of the present invention, Figures 1 to 3 As shown, the air conditioner indoor unit further includes a first baffle 152. The first baffle 152 is movably disposed in the housing 110 and configured to open the first communication port 1423 so that the first communication port 1423 and the inlet of the first air duct 142 are both connected to the outlet of the first air duct 142.

[0053] It can be seen from the above embodiment that the first connecting port 1423 is connected to the first air duct 142, and the mixed air inlet 190 is connected to the first connecting port 1423. In this embodiment, when the indoor unit of the air conditioner is working, the first baffle 152 is moved to open the first connecting port 1423, so that the first connecting port 1423 and the inlet of the first air duct 142 are both connected to the outlet of the first air duct 142. Then the indoor air entering from the mixed air inlet 190 will enter the first air duct 142 from the first connecting port 1423, and then be mixed with the heat exchange air entering from the inlet of the first air duct 142, and then blown out from the outlet of the first air duct 142. In other words, the air blown out from the outlet of the first air duct 142 is a mixed air of indoor air and heat exchange air, which makes the heat exchange air blown out of the first air duct 142 more soothing than directly blowing out the heat exchange air. It further meets the diverse air supply needs of users and improves the user experience.

[0054] In some embodiments of the present invention, Figures 1 to 3 As shown, the air conditioner indoor unit further includes a second baffle 151. The second baffle 151 is movably disposed in the housing 110 and configured to close the second communication port 1413.

[0055] It can be seen from the above embodiment that the second communication port 1413 is connected to the second air duct 141, and the air mixing inlet 190 is connected to the second communication port 1413. In this embodiment, when the indoor unit of the air conditioner is working, the second baffle 151 is moved to close the second communication port 1413, so that the second air duct 141 is not connected to the air mixing inlet 190. At this time, the wind blown out of the second air duct 141 is relatively strong cold wind or warm wind, which meets the user's demand for rapid increase or decrease of indoor temperature, and further improves the user's use experience.

[0056] In some embodiments of the present invention, Figures 1 to 3 As shown, the air conditioner indoor unit further includes a second baffle 151. The second baffle 151 is movably disposed in the housing 110 and configured to disconnect the second air duct 141 and open the second communication port 1413 so that only the second communication port 1413 is connected to the outlet of the second air duct 141.

[0057] As can be seen from the above embodiment, the second communication port 1413 is connected to the second air duct 141, and the air mixing inlet 190 is connected to the second communication port 1413. In this embodiment, the second baffle 151 is movable to disconnect the second air duct 141, so that the second communication port 1413 is connected to the outlet of the second air duct 141. At this time, the indoor air enters the second air duct 141 through the second communication port 1413, and then blows out from the outlet of the second air duct 141, so that the outlet of the second air duct 141 blows out the indoor air, so as to meet the diverse air supply needs of users.

[0058] In some embodiments of the present invention, Figures 1 to 3 As shown, the air conditioner indoor unit further includes a second baffle 151. The second baffle 151 is movably disposed in the housing 110 and configured to open the second communication port 1413 so that the second communication port 1413 and the inlet of the second air duct 141 are both connected to the outlet of the second air duct 141.

[0059] It can be seen from the above embodiment that the second connecting port 1413 is connected to the second air duct 141, and the mixed air inlet 190 is connected to the second connecting port 1413. In this embodiment, when the indoor unit of the air conditioner is working, the second baffle 151 is moved to open the second connecting port 1413, so that the second connecting port 1413 and the inlet of the second air duct 141 are both connected to the outlet of the second air duct 141. Then the indoor air entering from the mixed air inlet 190 will enter the second air duct 141 from the second connecting port 1413, and then be mixed with the heat exchange air entering from the inlet of the second air duct 141, and then blown out from the outlet of the second air duct 141. In other words, the air blown out from the outlet of the second air duct 141 is a mixed air of indoor air and heat exchange air, which makes the heat exchange air blown out from the second air duct 141 more soothing than directly blowing out the heat exchange air. It further meets the diverse air supply needs of users and improves the user experience.

[0060] In some embodiments of the present invention, Figures 1 to 3 As shown, the indoor unit of the air conditioner is provided with a first baffle 152 and a second baffle 151. That is, the first air duct 142 and the second air duct 141 both have a mode of blowing out heat exchange air, a mode of blowing out mixed air, and a mode of blowing out indoor air. The indoor unit of the air conditioner is further provided with a variety of air outlet modes to meet the diverse air outlet needs of users and improve the market competitiveness of the indoor unit of the air conditioner.

[0061] In some embodiments of the present invention, Figures 1 to 3 As shown, the first baffle 152 is rotatably disposed in the first air duct 142 around the rear edge of the first communication opening 1423 , and the second baffle 151 is rotatably disposed in the second air duct 141 around the rear edge of the second communication opening 1413 .

[0062] In this embodiment, when the air outlet mode of the first air duct 142 is switched, the first baffle 152 is rotated so that the first baffle 152 rotates around the rear edge of the first air duct 142. When the air outlet mode of the second air duct 141 is switched, the second baffle 151 is rotated so that the second baffle 151 rotates around the rear edge of the second air duct 141. Since the first baffle 152 is rotatably arranged at the rear edge of the first connecting port 1423 and the second baffle 151 is rotatably arranged at the rear edge of the second connecting port 1413, there are more areas for mixing indoor air and heat exchange air in the first air duct 142 and the second air duct 141, which is convenient for mixing indoor air and mixed hot air. Moreover, the first baffle 152 rotates around the rear edge of the first air duct 142, so that the airflow direction of the indoor air entering from the first connecting port 1423 and the airflow direction of the heat exchange air entering from the inlet of the first air duct 142 are roughly consistent, which is conducive to the mixing and flow of airflow. The second baffle 151 rotates around the rear edge of the second air duct 141, so that the airflow direction of the indoor air entering from the second connecting port 1413 is roughly consistent with the airflow direction of the heat exchange air entering from the inlet of the second air duct 141, which is beneficial to the mixing and flow of the airflow.

[0063] In some embodiments of the present invention, Figures 1 to 3 As shown, the indoor unit of the air conditioner further includes a first guide plate 162. The first guide plate 162 is disposed in the housing 110 and between the first air duct 142 and the second air duct 141. The edge of the first guide plate 162 adjacent to the first air duct 142 is located obliquely behind the corresponding other edge of the first guide plate 162.

[0064] In this embodiment, when the first communication port 1423 is in an open state, the indoor air entering from the air mixing inlet 190 will pass through the first guide plate 162 to reach the first air duct 142. The first guide plate 162 is provided to facilitate better introduction of indoor air into the first air duct 142.

[0065] In some embodiments of the present invention, Figures 1 to 3 As shown, the air conditioner indoor unit further includes a second guide plate 161. The second guide plate 161 is disposed in the housing 110 and between the first air duct 142 and the second air duct 141. The edge of the second guide plate 161 adjacent to the second air duct 141 is located obliquely rearward of the corresponding other edge of the second guide plate 161.

[0066] In this embodiment, when the second communication port 1413 is in an open state, the indoor air entering from the air mixing inlet 190 will pass through the second guide plate 161 to reach the second air duct 141. The second guide plate 161 is provided to facilitate better introduction of indoor air into the second air duct 141.

[0067] In some embodiments of the present invention, Figures 1 to 3As shown, the indoor unit of the air conditioner is provided with a first guide plate 162 and a second guide plate 161. The first guide plate 162 is adjacent to the first air duct 142, and the second guide plate 161 is adjacent to the second air duct 141. That is, a part of the indoor air entering through the mixed air inlet 190 enters the first air duct 142 through the first guide plate 162, and the other part enters the second air duct 141 through the second guide plate 161.

[0068] In some embodiments of the present invention, Figures 1 to 3 As shown, the first baffle 152 is provided with a first plate body 1521. When the first baffle 152 closes the first communication port 1423, the first plate body 1521 is located at the rear side of the first guide plate 162, and the first plate body 1521 contacts the first guide plate 162. The first plate body 1521 is parallel to the first guide plate 162. The first guide plate 162 contacts the first baffle 152.

[0069] In this embodiment, when the first communication port 1423 needs to be closed, the first baffle 152 is rotated counterclockwise, and when the first plate body 1521 on the first baffle 152 reaches the rear side of the first guide plate 162 and contacts the first guide plate 162, the first baffle 152 reaches the closed position. The first plate body 1521 is set to limit the first baffle 152, ensuring that the first baffle 152 can reach the position of closing the first communication port 1423. Since the first plate body 1521 is parallel to the first guide plate 162, and the first plate body 1521 contacts the first guide plate 162 when the first communication port 1423 is closed, the first plate body 1521 is connected to the first guide plate 162 when the first communication port 1423 is opened, so as to better guide the indoor air.

[0070] In some alternative embodiments of this embodiment, the first plate body 1521 is located in front of the first guide plate 162 .

[0071] In some embodiments of the present invention, Figures 1 to 3 As shown, the second baffle 151 is provided with a second plate body 1511. When the second baffle 151 closes the second communication port 1413, the second plate body 1511 is located at the rear side of the second guide plate 161, and the second plate body 1511 contacts the second guide plate 161. The second plate body 1511 is parallel to the second guide plate 161. The second guide plate 161 contacts the second baffle 151.

[0072] In this embodiment, when the second communication port 1413 needs to be closed, the second baffle 151 is rotated clockwise, and when the second plate body 1511 on the second baffle 151 reaches the rear side of the second guide plate 161 and contacts the second guide plate 161, the second baffle 151 reaches the closed position. The second plate body 1511 is set to limit the second baffle 151, ensuring that the second baffle 151 can reach the position of closing the second communication port 1413. Since the second plate body 1511 is parallel to the second guide plate 161, and the second plate body 1511 contacts the second guide plate 161 when the second communication port 1413 is closed, the second plate body 1511 is connected to the second guide plate 161 when the second communication port 1413 is opened, so as to better guide the indoor air.

[0073] In some alternative embodiments of this embodiment, the second plate body 1511 is located in front of the second guide plate 161 .

[0074] In some embodiments of the present invention, Figures 1 to 3 As shown, the indoor unit of the air conditioner further includes a fan mounting frame 171, the fan mounting frame 171 is vertically arranged, and the air mixing fan is installed on the front side of the fan mounting frame 171. The first guide plate 162 and the second guide plate 161 are located on both sides of the fan mounting frame 171. The air mixing fan 172 is an axial flow fan.

[0075] In this embodiment, when the indoor unit of the air conditioner is working, the axial flow fan 172 rotates on the fan mounting frame 171.

[0076] In some embodiments of the present invention, there are multiple air mixing fans, which are arranged in sequence along the vertical direction.

[0077] In this embodiment, a plurality of axial flow fans 172 operate simultaneously, thereby improving the efficiency of indoor air entering the air mixing inlet 190 and further improving the air mixing efficiency of the indoor unit of the air conditioner.

[0078] In some embodiments of the present invention, Figures 1 to 3 As shown, a first crossflow fan 132 is disposed in the first air duct 142, the first crossflow fan 132 is disposed vertically, and the side wall of the first air duct 142 facing the second air duct 141 is a first volute profile 1421 that matches the first crossflow fan 132. The first baffle 152 is a part of the first volute profile 1421 when the first communication port 1423 is closed.

[0079] In this embodiment, when the first cross-flow fan 132 is working, the heat exchange air generated by the first cross-flow fan 132 is blown out along the first volute profile 1421 toward the outlet direction of the first air duct 142. Since the first baffle 152 is a part of the first volute profile 1421 when the first connecting port 1423 is closed, it can be known from the above embodiment that the indoor air enters the first air duct 142 through the first baffle 152. Then when the first connecting port 1423 is opened, the heat exchange air and the indoor air enter the air mixing section of the first air duct 142 from the two sides of the first baffle 152 respectively, so that the heat exchange air and the indoor air can be better mixed.

[0080] In some embodiments of the present invention, Figures 1 to 3 As shown, a second crossflow fan 131 is disposed in the second air duct 141, the second crossflow fan 131 is disposed vertically, and the side wall of the second air duct 141 facing the first air duct 142 is a second volute profile 1411 that cooperates with the second crossflow fan 131. The second baffle 151 is a part of the second volute profile 1411 when the second communication port 1413 is closed.

[0081] In this embodiment, when the second cross-flow fan 131 is working, the heat exchange air generated by the second cross-flow fan 131 is blown out along the second volute profile 1411 toward the outlet direction of the second air duct 141. Since the second baffle 151 is a part of the second volute profile 1411 when the second connecting port 1413 is closed, it can be known from the above embodiment that the indoor air enters the second air duct 141 through the second baffle 151. Then when the second connecting port 1413 is opened, the heat exchange air and the indoor air enter the air mixing section of the second air duct 141 along the two sides of the second baffle 151 respectively, so that the heat exchange air and the indoor air can be better mixed.

[0082] In some embodiments of the present invention, Figures 1 to 3 As shown, the width of the first communication port 1423 in the front-to-back direction is greater than the width of the second communication port 1413 in the front-to-back direction.

[0083] In some alternative embodiments, the width of the first communication port 1423 in the front-to-back direction is equal to the width of the second communication port 1413 in the front-to-back direction. Alternatively, the width of the first communication port 1423 in the front-to-back direction is smaller than the width of the second communication port 1413 in the front-to-back direction.

[0084] In some embodiments of the present invention, Figures 1 to 3 As shown, along the direction from back to front, the distance between the first air duct 142 and the second air duct 141 first gradually increases and then remains unchanged.

[0085] It can be seen from the above embodiment that the side wall of the first air duct 142 facing the second air duct 141 is a first volute profile 1421 that matches the first cross-flow fan 132, and the side wall of the second air duct 141 facing the first air duct 142 is a second volute profile 1411 that matches the second cross-flow fan 131, that is, the first volute profile 1421 and the second volute profile 1411 are arranged adjacent to each other. And a cross-flow fan is arranged between the first air duct 142 and the second air duct 141. In this embodiment, in the direction from back to front, the distance between the first air duct 142 and the second air duct 141 first gradually increases to avoid the installation space of the cross-flow fan, and after avoiding enough installation space, the distance between the first air duct 142 and the second air duct 141 remains unchanged.

[0086] Furthermore, since the distance between the first air duct 142 and the second air duct 141 gradually increases and then remains unchanged, that is, the outlet of the first air duct 142 and the outlet of the second air duct 141 are spaced apart, the air outlet range of the air conditioner indoor unit is expanded, thereby improving the working efficiency of the air conditioner indoor unit.

[0087] In some alternative embodiments of the present embodiment, the distance between the first air duct 142 and the second air duct 141 gradually increases from the back to the front.

[0088] In some embodiments of the present invention, Figures 1 to 3 As shown, the indoor unit of the air conditioner further includes a first air guide plate 1422 and a second air guide plate 1412. The first air guide plate 1422 is rotatably disposed around a vertical axis at the outlet of the first air duct 142, and the first air guide plate 1422 is configured to promote the airflow to flow in a direction away from the air mixing inlet 190. The second air guide plate 1412 is rotatably disposed around a vertical axis at the outlet of the second air duct 141. The second air guide plate 1412 is configured to promote the airflow to flow in a direction away from the air mixing inlet 190.

[0089] In this embodiment, when the indoor unit of the air conditioner is working, the indoor air enters the housing 110 through the air mixing inlet 190, and then a part of the indoor air enters the first air duct 142 through the first baffle 152, and then mixes with the heat exchange air in the first air duct 142, and finally reaches the outlet of the first air duct 142, and then blows out to the room through the first air guide plate 1422. Another part enters the second air duct 141 through the second baffle 151, and then mixes with the heat exchange air in the second air duct 141, and then reaches the outlet of the second air duct 141, and then blows out to the room through the second air guide plate 1412. Since the first air guide plate 1422 and the second air guide plate 1412 are rotatable, that is, the first air guide plate 1422 and the second air guide plate 1412 can guide air in multiple directions, thereby expanding the air outlet range of the indoor unit of the air conditioner.

[0090] In some embodiments of the present invention, Figures 1 to 3 As shown, an air purification device is provided at the mixed air inlet 190. A heat exchanger 120 is provided at the inlet of the first air duct 142 and the second air duct 141.

[0091] In this embodiment, the indoor air enters the housing 110 from the mixed air inlet 190 through the air purification device, and then a part of the indoor air enters the first air duct 142 through the first baffle 152, and then mixes with the heat exchange air in the first air duct 142. Since the air purification device is provided at the mixed air inlet 190, the indoor air entering the housing 110 is filtered, thereby ensuring the purity of the air blown out by the indoor unit of the air conditioner and protecting the health of the user.

[0092] In some embodiments of the present invention, Figures 1 to 3 As shown, the air purification device is a filter 180. Indoor air passes through the filter 180 and enters the housing 110.

[0093] In some embodiments of the present invention, Figures 4 to 5 As shown, the outlet of the first air duct 142, the outlet of the second air duct 141 and the air mixing inlet 190 are all in the shape of long strips and extend in the vertical direction. In this embodiment, the shape of the air mixing inlet 190 can inhale more indoor air, and the shapes of the outlet of the first air duct 142 and the outlet of the second air duct 141 make the air outlet range larger, further enhancing the air mixing effect.

[0094] In some alternative embodiments of this embodiment, the heat exchanger 120 is only disposed at the inlet of the first air duct 142. That is, only the outlet of the first air duct 142 can blow out the heat exchange air.

[0095] In some alternative embodiments of the present embodiment, the heat exchanger 120 is only provided at the inlet of the second air duct 141. That is, only the outlet of the second air duct 141 can blow out the heat exchange air.

[0096] In some alternative embodiments of this embodiment, the indoor unit of the air conditioner only includes the first air guide plate 1422. Only the air supply range of the outlet of the first air duct 142 is expanded.

[0097] In some alternative embodiments of this embodiment, the indoor unit of the air conditioner only includes the second air guide plate 1412. Only the air supply range of the outlet of the second air duct 141 is expanded.

[0098] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention.
