[0057] A floor-standing air conditioner can place the indoor unit of the floor-standing air conditioner indoors to heat or cool the indoor air.

[0058] In order to make the heating or cooling effect more uniform and the user more comfortable, the existing cabinet air conditioner is provided with an air outlet duct 11 extending in the vertical direction in the indoor unit. When cooling, the cold air enters the room from the upper air outlet 111 through the air outlet duct 11. Since the cold air has a larger density, it sinks and mixes with the indoor air, causing the indoor temperature to drop rapidly. When heating, the hot air enters the room from the lower air outlet 113 through the air outlet duct 11. Since the hot air has a smaller density, it floats and mixes with the indoor air, causing the indoor temperature to rise rapidly.

[0059] However, when the air conditioner is heating, since only the lower air outlet 113 of the air outlet duct 11 is opened, the air outlet efficiency of the duct is not high. In addition, since the density of hot air is relatively small, some hot air will rise and accumulate at the bottom of the air outlet duct 11, affecting the heat exchange efficiency of the air conditioner and causing waste of resources.

[0060] Embodiment 1

[0061] Based on this, Figure 1-Figure 13 As shown, the indoor unit of the air conditioner according to the embodiment of the utility model comprises: a housing 1, an air outlet duct 11 extending in a vertical direction is formed inside the housing 1;

[0062] The air outlet duct 11 has an upper air outlet 111, which is located at the top of the air outlet duct 11 and is arranged toward the top of the air outlet duct 11 for discharging cold air;

[0063] The air outlet duct 11 also has a lower air outlet 113 and a front air outlet 112. The lower air outlet 113 is located at the bottom of the air outlet duct 11 and is arranged toward the front of the air outlet duct 11. The front air outlet 112 is located in the top side area of ​​the front part of the air outlet duct 11, and the air outlet direction of the front air outlet (112) is arranged toward the oblique downward direction of the air outlet duct 11. The lower air outlet 113 and the front air outlet 112 are used to discharge hot air together.

[0064] Specifically, the air conditioner indoor unit is applied to an air conditioner, and the air conditioner can be a vertical cabinet air conditioner. The air conditioner indoor unit is a cabinet structure. When the air conditioner indoor unit is cooling or heating, the cold air or hot air is discharged through the air outlet duct 11 to cool or heat the room.

[0065] The air outlet duct 11 extends in the vertical direction, which means that the entire duct extends in a roughly vertical direction, and does not necessarily mean that it is a straight air outlet duct. The upper air outlet 111 of the air outlet duct 11 is set at the top, and the lower air outlet 113 is set at the bottom. Corresponding switch structures can be set in the upper air outlet 111 and the lower air outlet 113 to control the switches of the upper air outlet 111 and the lower air outlet 113. When the air conditioner is heated, the upper air outlet 111 is closed and the lower air outlet 113 is opened, so that hot air is discharged from the bottom. The hot air is discharged from the outlet 113, and the hot air has a low density and floats upward, so that the hot air floats upward from the lower part of the room and mixes with the indoor air to quickly increase the indoor temperature. When the air conditioner is cooling, the upper air outlet 111 is opened and the lower air outlet is closed, so that the cold air is discharged from the upper air outlet 111, and the cold air has a high density and settles downward, so that the cold air is deposited from the upper part of the room. Through this up and down air outlet method, the characteristics of the hot air and the cold air themselves can be used to quickly heat or cool the room, thereby improving the user experience.

[0066] The present application also provides a front air outlet 112 on the front side of the air outlet duct 11. The front air outlet 112 is provided in the top side area of ​​the front part of the air outlet duct 11, so that the hot air that rises and accumulates on the top of the air outlet duct 11 can be discharged, so as to avoid the accumulation of hot air in the air outlet duct 11, which affects the heat exchange efficiency of the air conditioner and causes waste of resources. The front air outlet 112 cooperates with the lower air outlet 113 to discharge air, which can effectively improve the air outlet efficiency and the heating efficiency. The front air outlet 112 faces obliquely downward, and can guide the hot air downward. The hot air discharged from the front air outlet 112 cooperates with the hot air from the lower air outlet 113 to form an effect similar to two-stage heating, which can better and more evenly increase the room temperature.

[0067] The hot air is discharged through the lower air outlet 113 of the air outlet 11, so that the hot air floats up from the bottom and mixes with the indoor air, so that the indoor temperature rises rapidly for heating, thereby achieving the technical effect of rapidly increasing the indoor temperature. Moreover, in the present application, a front air outlet 112 with an opening facing obliquely downward is provided on the front side of the air outlet 11. When the air conditioner is heating, the hot air is discharged together with the front air outlet 112 and the lower air outlet 113. An air outlet is added, which can effectively improve the air outlet efficiency of the air outlet 11. Moreover, the front air outlet 112 is provided in the top side area of ​​the front part of the air outlet 11, so as to discharge the hot air that rises and accumulates on the top of the air outlet 11, thereby avoiding the accumulation of hot air in the air outlet 11, which affects the heat exchange efficiency of the air conditioner and causes waste of resources.

[0068] In some embodiments, the air conditioner indoor unit further includes:

[0069] The upper door assembly 2 is arranged at the upper air outlet 111;

[0070] A lower door assembly, arranged at the lower air outlet 113;

[0071] A front door assembly 3, arranged at the front air outlet 112;

[0072] The working relationship between the upper door assembly (2), the lower door assembly and the front door assembly (3) is set as follows:

[0073] When the air conditioner is cooling, the upper door assembly (2) opens the upper air outlet (111), and the lower door assembly and the front door assembly (3) close the lower air outlet (113) and the front air outlet (112);

[0074] When the air conditioner is heating, the upper door assembly (2) closes the upper air outlet (111), and the lower door assembly and the front door assembly (3) open the lower air outlet (113) and the front air outlet (112).

[0075] The air conditioner indoor unit is provided with a controller, and the controller can realize the control of the working relationship between the upper door assembly (2), the lower door assembly and the front door assembly (3). Specifically, when the air conditioner is cooling, the upper door assembly 2 is controlled to open the upper air outlet 111 and the lower door assembly and the front door assembly 3 are controlled to close the lower air outlet 113 and the front air outlet 112; when the air conditioner is heating, the upper door assembly 2 is controlled to close the upper air outlet 111 and the lower door assembly and the front door assembly 3 are controlled to open the lower air outlet 113 and the front air outlet 112.

[0076] Specifically, the controller can be set in the indoor unit of the air conditioner. The controller can obtain the heating state or the cooling state of the air conditioner, and then automatically control the switching of the upper air outlet 111, the lower air outlet 113 and the front air outlet 112 according to the cooling state or the heating state. The user does not need to manually open and close the air outlet, which can improve the user experience.

[0077] In some embodiments, the front door assembly 3 includes:

[0078] The box body 31 is arranged on the top side of the front part of the air outlet duct 11, the rear side of the box body 31 has an air inlet end 311, the bottom side of the box body 31 has an air outlet end 312, and the interior of the box body 31 has a cavity 313 connected with the air inlet end 311 and the front air end;

[0079] The air inlet end 311 is connected to the front side of the air outlet duct 11, and the air outlet end 312 is used to communicate with the external environment. The housing 1 has an inclined air guide surface 12 below the air outlet end 312, and the air guide surface 12 is inclined from the bottom of the air outlet duct 11 to the bottom of the air outlet duct 11 toward the front side of the air outlet duct 11;

[0080] The air inlet end 311 , the cavity 313 , the air outlet end 312 and the air guide surface 12 form a front air outlet 112 which is obliquely downward and faces the air outlet duct 11 .

[0081] Specifically, the oblique downward direction of the front air outlet 112 is achieved by the cooperation of the box body 31 and the air guide surface 12, wherein the box body 31 takes in air through the air inlet end 311, and the hot air enters the cavity 313 and is discharged from the air outlet end 312, and the discharged hot air is directly blown onto the air guide surface 12, and the inclined setting of the air guide surface 12 can guide the hot air and make the hot air blow out obliquely downward, so that the hot air can be better mixed with the indoor air, and the air outlet height of the front air outlet 112 is higher than that of the lower air outlet 113, and can form a two-end heating effect with the hot air from the lower air outlet 113, so that the indoor temperature rises faster and more evenly.

[0082] In some embodiments, the front door assembly 3 further includes:

[0083] A driving mechanism 32, the driving mechanism 32 is disposed in the cavity 313;

[0084] A first baffle 33, the first baffle 33 is in transmission cooperation with the driving mechanism 32;

[0085] The driving mechanism 32 is used to drive the first baffle 33 to close the cavity 313 when the front door assembly 3 closes the front air outlet 112 , and to drive the first baffle 33 to open the cavity 313 when the front door assembly 3 opens the front air outlet 112 .

[0086] Specifically, the driving mechanism 32 can be a driving motor that drives the rotating shaft to rotate. The first baffle 33 is connected to the rotating shaft, and the first baffle 33 is driven by the rotating shaft to rotate to achieve transmission coordination. The first baffle 33 can close the cavity 313 and close the front air outlet 112 under the drive of the driving motor, and can also open the cavity 313 and open the front air outlet 112 under the drive of the driving motor.

[0087] In some embodiments, the first baffle 33 has a vertical plate 331 and a horizontal plate 332. The vertical plate 331 is connected to the driving mechanism 32, and the horizontal plate 332 is located at the lower end of the vertical plate 331. When the first baffle 33 opens the cavity 313, the horizontal plate 332 is tilted to guide the hot air to the oblique lower part of the air outlet duct 11.

[0088] Specifically, the first baffle 33 can be an L-shaped plate. When the first baffle 33 opens the cavity 313, the horizontal plate 332 tilts from top to bottom toward the front side of the air inlet duct, which can guide the hot air and make the hot air be discharged downward, cooperating with the air guide surface 12 to guide the outflow of air.

[0089] In some embodiments, the box body 31 has a sealing rib 34 at the top of the cavity 313 . When the first baffle plate 33 closes the cavity 313 , the sealing rib 34 overlaps and cooperates with the vertical plate 331 to further close the cavity 313 .

[0090] Specifically, the sealing rib 34 cooperates with the vertical plate 331, and the position of the sealing rib 34 does not affect the rotation of the first baffle 33. However, when the first baffle 33 rotates to close the cavity 313, the horizontal plate 332 cooperates with the air outlet end 312, and the vertical plate 331 is placed on the sealing rib 34, which can further close the cavity 313 and prevent cold air from leaking from the side of the vertical plate 331 when the air conditioner is cooling.

[0091] In some embodiments, the box body 31 is provided with a second baffle 35 in the cavity 313, the top of the second baffle 35 is rotatably connected to the top of the box body 31, and the bottom of the second baffle 35 is slidably matched with the first baffle 33;

[0092] When the first baffle 33 closes the cavity 313 , the second baffle 35 closes the air inlet end 311 of the box body 31 . When the first baffle 33 opens the cavity 313 , the second baffle 35 and the cross plate 332 are tilted together to guide the hot air obliquely downward of the air outlet duct 11 .

[0093] Specifically, the second baffle 35 can be slidably connected to the upper surface of the first baffle 33, or it can be simply overlapped on the upper surface of the first baffle 33. As long as it can slide with the first baffle 33, when the first baffle 33 rotates, the second baffle 35 also rotates accordingly. When the first baffle 33 blocks the air outlet end 312, the second baffle 35 can block the air inlet end 311, forming a double sealing effect, thereby improving the sealing performance of the front door assembly 3. When the first baffle 33 opens the cavity 313 and is tilted, the second baffle 35 is also tilted to guide the hot air and prevent the hot air from entering the side of the vertical plate 331, causing swirl and affecting the air outlet effect.

[0094] In some embodiments, the inner side of the first baffle 33 facing away from the air outlet end 312 further has a heat preservation layer 36 .

[0095] Specifically, the insulation layer 36 can be a layer of insulation foam, which can increase the insulation function of the first baffle 33, reduce the heat exchange of hot air or cold air at the outlet, and enable the hot air or cold air to be discharged normally and exchange heat with the indoor air, thereby improving the heat exchange efficiency.

[0096] In some embodiments, the air conditioner indoor unit further includes: an air inlet duct, a heat exchanger 4 and a centrifugal fan 5;

[0097] The air outlet duct has an upper air duct 114 and a lower air duct 115;

[0098] The centrifugal fan 5 is arranged in the housing 1, and the centrifugal fan 5 has a first air outlet, a second air outlet and an air inlet;

[0099] The heat exchanger 4 is arranged at the air inlet end of the air inlet duct, the air inlet end of the air inlet duct is arranged at the rear of the shell 1, the air outlet end of the air inlet duct is connected to the air inlet, the first air outlet is connected to the upper air duct 114, and the second air outlet is connected to the lower air duct 115.

[0100] In some embodiments, the air conditioner indoor unit further includes: a flow guide 6;

[0101] The air guide 6 is arranged on the inner wall of the upper air duct, and the air guide 6 can be driven to move. When driven to move, the air guide 6 has a switchable first position and a second position;

[0102] When the upper door assembly 2 opens the upper air outlet 111, and the lower door assembly and the front door assembly 3 close the lower air outlet 113 and the front air outlet 112, the air guide 6 moves to the first position to guide the cold air flow in the upper air duct 114 to the upper air outlet;
