[0050] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0051] like Figure 1 As shown, the air guide assembly of this utility model embodiment includes a housing 1, a first opening and closing member 2, and a second opening and closing member 3.

[0052] The outer casing 1 is provided with a casing inlet 17, a first outlet 18 and a second outlet 19. The casing inlet 17 is used for airflow to flow in, and the first outlet 18 and the second outlet 19 are both used for airflow to flow out. The second outlet 19 is located on the bottom side of the outer casing 1.

[0053] For example, the outer shell 1 can generally be a box-type structure, which can be assembled from some plates or it can be an integral structure. The shell inlet 17 can be located on the rear shell wall of the outer shell 1, the first outlet 18 can be located on the front or top shell wall of the outer shell 1, and the second outlet 19 can be located on the bottom shell wall of the outer shell 1.

[0054] The first opening / closing element 2 and the second opening / closing element 3 are both located on the outer casing 1. The first opening / closing element 2 is used to open and close the first outlet 18, and the second opening / closing element 3 is used to open and close the second outlet 19. For example, both the first opening / closing element 2 and the second opening / closing element 3 can be plate-shaped structures, and their positions relative to the outer casing 1 can be adjusted. The specific implementation of the position adjustment can be sliding, rotating, or swivel. When the first opening / closing element 2 and the second opening / closing element 3 are rotated to their respective positions, the first outlet 18 or the second outlet 19 can be opened or closed.

[0055] In some other embodiments, the first opening and closing element 2 and the second opening and closing element 3 may also be valve-like structures, thereby enabling the first outlet 18 and the second outlet 19 to open and close automatically.

[0056] The air guide assembly has a heating mode and a cooling mode. Specifically, due to the adjustable positions of the first shutter 2 and the second shutter 3 relative to the shell 1, the air guide assembly can freely switch between the heating mode and the cooling mode by adjusting the positions of the first shutter 2 and the second shutter 3.

[0057] In the heating mode, the first shutter 2 closes the first outlet 18, and the second shutter 3 opens the second outlet 19. For example, as shown in Figure 2 and Figure 3 At this time, the first shutter 2 can be adjusted to a substantially vertical position, the first shutter 2 can completely seal the first outlet 18, and the second shutter 3 can be adjusted to a vertical position, thereby achieving the opening of the second outlet 19.

[0058] When the heated heating airflow is introduced into the shell inlet 17, the heating airflow is forced to turn downward in the shell 1 due to the closed first outlet 18, and the heating airflow can finally flow out through the second outlet 19 at the bottom side, so that the heating airflow can directly reach the ground at the shortest distance and form a carpet wind or a warm foot wind, thereby improving the heating effect and use experience.

[0059] In the cooling mode, the first shutter 2 opens the first outlet 18, and the second shutter 3 closes the second outlet 19. For example, as shown in Figure 4 and Figure 5 At this time, the first shutter 2 can be arranged horizontally or obliquely, the first shutter 2 can unseal the first outlet 18, and the second shutter 3 can be adjusted to a substantially horizontal position, at this time, the second shutter 3 can cut off the airflow path between the shell inlet 17 and the second outlet 19, or the second shutter 3 can directly seal the second outlet 19.

[0060] When the cooled cooling airflow is introduced into the shell inlet 17, the cooling airflow can directly flow out through the first outlet 18, thereby meeting the use needs of providing cold air for cooling.

[0061] The air guide assembly of the embodiment of the utility model can blow the heating airflow to the ground and form a carpet wind or a warm foot wind, so that the temperature in the room can be uniformly distributed, the discomfort of human body temperature sensation is improved, and the overall use experience is improved.

[0062] In some embodiments, the first outlet 18 is arranged on the side wall of the shell 1 and adjacent to the top side of the shell 1, and the shell inlet 17 and the first outlet 18 are oppositely arranged. For example, as shown in Figure 1As shown, the first outlet 18 can be a rectangular opening, the first outlet 18 can be arranged on the shell wall of the front side of the outer shell 1, and the first outlet 18 can be arranged adjacent to the top side of the shell wall of the front side. The shell inlet 17 can be arranged on the shell wall of the rear side of the outer shell 1, and the shell inlet 17 and the first outlet 18 can be arranged opposite in the front-rear direction, so that the refrigeration airflow can directly flow out through the first outlet 18 after passing through the shell inlet 17, reducing the overall wind resistance and ensuring the air supply speed, efficiency and air volume.

[0063] In some embodiments, as Figure 1 As shown, the outer shell 1 includes a first plate 11, a second plate 12, a third plate 13 and a fourth plate 14.

[0064] The first plate 11 and the second plate 12 are arranged opposite to each other, the shell inlet 17 is arranged on the first plate 11, and the first outlet 18 is arranged on the second plate 12. The third plate 13 and the fourth plate 14 are arranged opposite to each other and are both arranged between the first plate 11 and the second plate 12.

[0065] For example, as Figure 1 As shown, the first plate 11 and the second plate 12 can both be generally rectangular plates, and the first plate 11 and the second plate 12 can be arranged apart in the front-rear direction, with the first plate 11 located in front of the second plate 12. The shell inlet 17 can be arranged on the first plate 11 and can be arranged adjacent to the top side edge of the first plate 11, and the first outlet 18 can be arranged on the second plate 12 and can be arranged adjacent to the top side edge of the second plate 12.

[0066] The third plate 13 and the fourth plate 14 are both vertical plates and can extend in a vertical plane perpendicular to the left-right direction. The front side edges of the third plate 13 and the fourth plate 14 can be connected and fixed with the second plate 12, and the rear side edges of the third plate 13 and the fourth plate 14 can be connected and fixed with the first plate 11.

[0067] As Figure 3 and Figure 5 As shown, the first plate 11, the second plate 12, the third plate 13 and the fourth plate 14 enclose an airflow passage 110 extending in the up-down direction. The airflow passage 110 can be a square passage as a whole, the port of the bottom end of the airflow passage 110 forms a second outlet 19, the first opening and closing member 2 is arranged at the first outlet 18, and the second opening and closing member 3 is arranged in the airflow passage 110. Specifically, the second opening and closing member 3 can be arranged below the shell inlet 17. In use, the second opening and closing member 3 can be swung to the shell inlet 17 by flipping, so as to achieve plugging and shielding of the shell inlet 17.

[0068] In some embodiments, the third plate 13 and the fourth plate 14 are symmetrically arranged and each includes a vertical segment 15 and a horizontal segment 16. The vertical segment 15 extends in the vertical direction, and the horizontal segment 16 extends horizontally and is connected to the bottom end of the vertical segment 15. The horizontal segments 16 of the third plate 13 and the fourth plate 14 are both located outside the vertical segment 15.

[0069] For example, such as Figure 1 As shown, the third plate 13 and the fourth plate 14 can both be roughly L-shaped plates. The third plate 13 and the fourth plate 14 each include two parts with different extension directions, namely the vertical section 15 and the horizontal section 16. The vertical section 15 extends along the vertical direction, while the horizontal section 16 extends along the horizontal direction.

[0070] The aforementioned airflow channel 110 can be formed between the vertical section 15 of the third plate 13 and the vertical section 15 of the fourth plate 14. The horizontal section 16 of the third plate 13 can be connected to the vertical section 15 of the third plate 13 and extend to the left of the vertical section 15, and the horizontal section 16 of the fourth plate 14 can be connected to the vertical section 15 of the fourth plate 14 and extend to the right of the vertical section 15.

[0071] The L-shaped design of the third plate 13 and the fourth plate 14 can enhance the structural strength and fully meet the needs of use. On the other hand, the horizontal section 16 can also cover the gap between the first plate 11 and the second plate 12, thereby improving the overall appearance.

[0072] In some embodiments, both the shell inlet 17 and the first outlet 18 are located between the vertical section 15 of the third plate 13 and the vertical section 15 of the fourth plate 14. For example, as Figure 1 As shown, both the shell inlet 17 and the first outlet 18 can be generally rectangular openings and can extend in the left and right directions. The length of the shell inlet 17 and the first outlet 18 in the left and right directions can be less than the distance between the vertical section 15 of the third plate 13 and the vertical section 15 of the fourth plate 14, so that the airflow can completely enter the airflow channel 110 and avoid air leakage.

[0073] In some embodiments, the first opening and closing member 2 is plate-shaped. In the heating mode, the first opening and closing member 2 is flush with the side wall of the outer casing 1. In the cooling mode, the first opening and closing member 2 is arranged at an angle upward so that the airflow flowing out from the first outlet 18 flows at an angle upward.

[0074] For example, such as Figure 3 As shown, when switching to heating mode, the first opening and closing component 2 can be arranged vertically. At this time, the first opening and closing component 2 can be flush with the front shell wall of the outer shell 1 and located in the same wall surface, thereby blocking the first outlet 18 and ensuring the overall appearance.

[0075] When switching to the cooling mode, as shown in Figure 5 the first opening and closing piece 2 can be arranged to tilt downward along the front-up-to-back-down direction, at this time, the air flow discharged through the first outlet 18 will also flow upwardly obliquely, so that the air flow entering the room environment will run along the room top wall, the air flow will be mixed with the indoor air during the running process, and finally a layer of substantially uniform cold air layer will be formed at the room top, and then the cold air layer will slowly descend, so that the room is uniformly cooled from top to bottom, avoiding the direct blowing to the human body, and improving the user experience.

[0076] In some embodiments, the air guide assembly includes a third opening and closing piece 4, which is arranged at the second outlet 19, and the third opening and closing piece 4 is used to open and close the second outlet 19, and in the heating mode, the third opening and closing piece 4 opens the second outlet 19, and in the cooling mode, the third opening and closing piece 4 closes the second outlet 19.

[0077] For example, as shown in Figure 1 the third opening and closing piece 4 can also be a plate structure, and the third opening and closing piece 4 can be rotatably assembled at the second outlet 19, as shown in Figure 3 when switching to the heating mode, the third opening and closing piece 4 can be adjusted to a substantially vertical position, at this time, the second outlet 19 is opened, and the heating air flow can flow out downwardly through the second outlet 19.

[0078] When switching to the cooling mode, as shown in Figure 4 the third opening and closing piece 4 can be adjusted to a substantially horizontal position, at this time, the second outlet 19 is closed, and through the joint action of the second opening and closing piece 3 and the third opening and closing piece 4, the blocking between the shell inlet 17 and the second outlet 19 can be realized, realizing two-layer plugging, and fully avoiding the leakage of cold air.

[0079] In some embodiments, the first opening and closing piece 2, the second opening and closing piece 3, and the third opening and closing piece 4 are rotatably assembled in the shell 1, the first opening and closing piece 2 realizes the opening and closing control of the first outlet 18 through rotation, and the second opening and closing piece 3 and the third opening and closing piece 4 both realize the opening and closing control of the second outlet 19 through rotation.

[0080] For example, the first opening and closing piece 2, the second opening and closing piece 3, and the third opening and closing piece 4 can all be plate structures, and the first opening and closing piece 2, the second opening and closing piece 3, and the third opening and closing piece 4 can all be provided with a pivot, which can extend along the left-right direction and can be rotatably assembled with the shell 5, thereby improving the convenience of installation of the first opening and closing piece 2, the second opening and closing piece 3, and the third opening and closing piece 4.

[0081] It should be noted that in order to realize the position adjustment of the three opening and closing members, a motor 73 or the like driving device can be assembled on each opening and closing member, and the corresponding pivot can be driven to rotate by the driving device, thereby realizing the turnover adjustment of each opening and closing member, and realizing the automation of the position adjustment.

[0082] The air conditioner of the utility model embodiment is described below.

[0083] The air conditioner of the utility model embodiment comprises a wind guide assembly, which can be the wind guide assembly described in any of the above embodiments. The air conditioner can be a wall-mounted air conditioner indoor unit.

[0084] In some embodiments, the air conditioner comprises a housing 5, a heat exchanger 6 and a centrifugal fan 7.

[0085] The housing 5 comprises a front plate 51 and a side plate 55, the side plate 55 is arranged at the end of the length direction of the housing 5, the side plate 55 is provided with a side air inlet 551, and the front plate 51 is provided with an air outlet communicated with the shell inlet 17, or the front plate 51 forms a part of the shell wall of the shell 1 provided with the shell inlet 17.

[0086] For example, as shown in Figures 6 to 7 The housing 5 can be generally cuboid, the length direction of the housing 5 can be the left-right direction, the front plate 51 can be the shell wall part of the front side of the housing 5, and the side plate 55 can be the shell wall part of the left side or the right side of the housing 5.

[0087] The housing 5 can comprise two side plates 55, the two side plates 55 can be arranged opposite in the left-right direction, the side air inlet 551 can be arranged on each side plate 55, and the side air inlet 551 can be arranged at the lower corner position of each side plate 55. The front plate 51 can be arranged independently of the above-mentioned shell 1, at this time, the air outlet can be a square opening, the air outlet can be arranged at the top of the front plate 51 and can extend along the left-right direction, and when assembled, the front plate 51 can be attached to the rear side of the first plate 11 of the shell 1, and the air outlet on the front plate 51 can be communicated with the shell inlet 17 on the first plate 11.

[0088] In other embodiments, the front plate 51 can also be integrally formed with the shell wall of the shell 1, that is, the front plate 51 of the housing 5 and the above-mentioned first plate 11 of the shell 1 can be integrated into one plate, at this time, the shell inlet 17 on the above-mentioned first plate 11 is also the air outlet. Thus, it is beneficial to simplify the overall structure arrangement.

[0089] The heat exchanger 6 is arranged in the housing 5 and divides the inner cavity of the housing 5 into a lower cavity 53 and an upper cavity 54 arranged opposite in the up-down direction, the side air inlet 551 is communicated with the lower cavity 53, and the shell inlet 17 is communicated with the upper cavity 54.

[0090] For example, as shown in Figure 7As shown, the heat exchanger 6 can be of a plate type structure, and can be a evaporator or a condenser, when being a evaporator, the heat exchanger 6 can cool the airflow, thereby meeting the use requirement of indoor cooling.

[0091] The heat exchanger 6 can be installed in the shell 5 and can be arranged obliquely downward along the front-up to back-down direction. The outer peripheral side of the heat exchanger 6 can be sealingly connected with the corresponding inner wall of the shell 5, thereby avoiding the case that the airflow flows through the gap between the heat exchanger 6 and the inner wall of the shell 5, and facilitating to improve the heat exchange effect.

[0092] It should be noted that the heat exchanger 6 can divide the shell 5 into two relatively independent chambers, that is, a lower chamber 53 located below the heat exchanger 6 and an upper chamber 54 located above the heat exchanger 6. The two side air inlets 551 on the two side plates 55 can be in communication with the left side and the right side of the lower chamber 53, respectively, and the air outlet can be in communication with the upper chamber 54.

[0093] As shown, Figure 7 The centrifugal fan 7 is arranged in the upper chamber 54 and is in communication with the shell inlet 17 and is used for discharging the airflow in the upper chamber 54 through the shell inlet 17. Specifically, when the centrifugal fan 7 operates, the external airflow can first flow into the lower chamber 53 through the two side air inlets 551, and then the airflow flows through the heat exchanger 6 and exchanges heat with the heat exchanger 6, thereby achieving heating or cooling of the airflow. The airflow adjusted in temperature enters the upper chamber 54, and then is transported to the air outlet under the action of the centrifugal fan 7 and is discharged through the air outlet. The discharged airflow enters the airflow channel 110 in the shell 1, and then is discharged through the first outlet 18 or the second outlet 19, thereby meeting the use requirement of supplying the carpet wind or the upwardly inclined cooling airflow.

[0094] The air conditioner of the embodiment of the utility model, the side air inlet is arranged on the side plate of the air conditioner, and the first outlet is arranged on the front side of the air conditioner, so that the air inlet direction and the air outlet direction are not in the same plane, thereby avoiding the case that the outlet airflow is easily sucked back by the air inlet, and improving the overall temperature adjustment effect of the air conditioner.

[0095] Secondly, the centrifugal fan has greater static pressure capacity than the conventional cross-flow fan, and can blow the airflow farther under the same airflow, thereby strengthening the sinking cooling effect of the airflow discharged through the air outlet, and when heating, the hot airflow can better reach the ground and form the warm foot wind effect, thereby improving the user experience.

[0096] In addition, by adopting the centrifugal fan and arranging the air inlet on the side plate, the overall size of the air conditioner can be reduced, the volume of the air conditioner is lowered, the air conditioner is miniaturized, and the temperature regulation needs of small space environment are met.

[0097] In some embodiments, as shown in Figure 8 The heat exchanger 6 includes a heat exchanger body 61 and a side plate 62, wherein the heat exchanger body 61 can be an evaporator or a condenser with heat exchange function, and the side plate 62 can be a structural member such as sheet metal.

[0098] The shell 5 includes a back plate 52 arranged opposite to the front plate 51, one side of the heat exchanger body 61 is connected to the front plate 51, the other side of the heat exchanger body 61 is connected to the back plate 52, and the side plate 55 has two side plates 55 arranged opposite in the length direction, and the heat exchanger body 61 is located between the two side plates 55.

[0099] For example, the front plate 51 can be a shell wall part of the front side of the shell 5, the back plate 52 can be a shell wall part of the rear side of the shell 5, and the front plate 51 and the back plate 52 can be arranged opposite in the front-rear direction.

[0108] Thus, the side plate 62 can block the upper side of the side air inlet 551, so that the airflow can only flow through the heat exchanger body 61, avoiding the case that the airflow directly passes over the heat exchanger body 61 through the gap between the heat exchanger body 61 and the side plate 55, and ensuring the heat exchange effect.

[0109] In some embodiments, the angle between the oblique edge opening and the horizontal direction is an angle a, and a≥45°. Specifically, as shown in Figure 10 , the angle between the oblique edge opening and the horizontal direction can be Figure 10 the angle between the projection L2a and the Y axis in FIG. 13, and the angle a can be specifically 45°, 50°, 55°, 60°, 65°, 70°, etc.
