[0043] Embodiment one

[0044] The air conditioner usually includes an indoor unit and an outdoor unit, and the indoor unit and the outdoor unit are connected through refrigerant pipes and cables.

[0045] The outdoor unit is usually provided with a casing and components such as a compressor, an outdoor heat exchanger, a throttling device, an outdoor fan and an electric control board arranged in the casing, and the indoor unit is usually provided with a casing, an indoor heat exchanger, an indoor fan and a control board, and the compressor, the outdoor heat exchanger, the throttling device and the indoor heat exchanger are connected by refrigerant pipelines to form a refrigeration circuit.

[0046] The casing of the indoor unit is usually provided with an air inlet and an air outlet, and under the action of the indoor fan, indoor air enters the casing through the air inlet, and after heat exchange with the indoor heat exchanger, the air is output to the outside from the air outlet to adjust the indoor temperature.

[0047] In order to reduce the problem of poor user experience caused by direct blowing of air conditioner air to the user during air conditioner operation.

[0048] As shown in Figure 1 The casing 1 of the indoor unit is used to be installed at the corner of the indoor wall, and the casing 1 has an air inlet 11 and at least one air outlet 12, and the air outlet 12 is used to send air outward along the wall of the indoor room.

[0049] The indoor heat exchanger is arranged in the casing 1, and the indoor heat exchanger is used to exchange heat with the air flowing between the air inlet 11 and the air outlet 12; the indoor fan is arranged in the casing 1 and is used to drive the air flow between the air inlet 11 and the air outlet 12.

[0050] In actual use, the casing 1 is installed at the corner of the indoor wall. Under the action of the indoor fan, indoor air enters the casing 1 through the air inlet 11, and the air exchanges heat with the indoor heat exchanger, and after heat exchange, the air is output through the air outlet 12.

[0051] The air output from the air outlet 12 will flow outward along the wall of the indoor room, and the air can effectively avoid being directly blown to the user's body during the flow along the wall. Moreover, by using the adsorption effect of the wall, the air can be maximized to flow along the wall, so that the heat-exchanged air can flow to a relatively far distance in the indoor room. Thus, the temperature distribution in the indoor room is more uniform.

[0052] Among them, for the arrangement position of the air inlet 11 and the air outlet 12 on the casing 1. Preferably, an embodiment is that the side of the casing 1 is respectively provided with the air outlet 12, and the panel of the casing 1 is provided with the air inlet 11.

[0053] Since the shell 1 is arranged at the corner of the indoor wall, after installation, the panel of the shell 1 is arranged downward, and air is sucked from the front through the air inlet 11. The air outlets 12 are distributed on the side of the shell 1, so that the air outlets 12 can be close to the corresponding wall, and the air output from the air outlets 12 can flow along the wall effectively.

[0054] According to the needs, multiple air outlets 12 can be arranged on the shell 1, and the air outlets 12 at different positions can send air along the wall on the corresponding side, so that the temperature regulation in the room is more rapid and efficient.

[0055] In addition, in order to meet the air outlet requirements of the multiple air outlets 12 on the side, the structure and installation mode of the indoor fan and the indoor heat exchanger at least have the following cases.

[0056] In some embodiments, the indoor fan can adopt a centrifugal fan, the centrifugal fan is provided with an air outlet for air outlet in the circumferential direction, one end surface of the centrifugal fan is provided with an air inlet for air inlet, and the air inlet of the centrifugal fan faces the air inlet 11.

[0057] The centrifugal fan can send air to the air outlets 12 at different positions through the air outlets in the circumferential direction, so as to ensure that each air outlet 12 can obtain balanced air volume; at the same time, the air inlet of the centrifugal fan is arranged opposite to the air inlet 11, which can also meet the air inlet requirements.

[0058] For the case of using the centrifugal fan, the indoor heat exchanger can be a fin heat exchanger with a plate structure, and the indoor heat exchanger covers the air inlet 11. Air enters the shell 1 from the air inlet 11, and the air is heated by the indoor heat exchanger and then enters the centrifugal fan. The centrifugal fan sends air to the air outlets 12 on the periphery in the circumferential direction, so that the heated air is output from the air outlets 12 at different positions.

[0059] Similarly, for the case of using the centrifugal fan, the indoor heat exchanger can be arranged in the circumferential direction of the centrifugal fan in a ring structure. Air enters the shell 1 from the air inlet 11, and the air enters the centrifugal fan. The air output by the centrifugal fan in the circumferential direction is heated by the indoor heat exchanger on the outside, so that the heated air is output from the air outlets 12 at different positions.

[0060] In some embodiments, the indoor fan can adopt a cross-flow fan, and each air outlet 12 is provided with the cross-flow fan on the air inlet side. By using the cross-flow fan, on the one hand, the air outlet 12 at different positions can meet the air outlet requirements, and on the other hand, the operation parameters of the cross-flow fan in different air outlets 12 can be adjusted according to the needs to realize the adjustment of the air volume in different directions. For the case of using the centrifugal fan, the indoor heat exchanger can be a fin heat exchanger of a plate structure, and the indoor heat exchanger covers the air inlet 11.

[0061] Embodiment two

[0062] As shown in Figures 2-7 Based on the above embodiment one, the difference is that the shell 1 is a triangular structure, wherein the shell 1 is provided with three air outlets 12, the air outlet 12 arranged on the panel 101 of the shell 1 is the first air outlet 121, the first air outlet 121 is distributed on both sides of the air inlet 11, and the air outlet 12 arranged on the top of the side wall 102 of the shell 1 is the second air outlet 122.

[0063] Among them, the first air outlet 121 sends air outward along the wall A of the side of the indoor, and the second air outlet 122 sends air outward along the wall B of the top of the indoor. The shell 1 generally includes a back plate 101 and a panel 102, both of which are triangular structures. The back plate 101 is used to be installed at the corner of the indoor wall, and the back plate 101 is provided with a baffle 1011, and the second air outlet 122 is arranged on the baffle 1011. The panel 102 is arranged on the back plate 101, and the installation cavity is formed between the panel 102 and the back plate 101, and the indoor heat exchanger and the indoor fan are arranged in the installation cavity; the air inlet 11 and the first air outlet 121 are arranged on the panel 102.

[0064] In actual use, the air output by the first air outlet 121 on both sides of the panel 102 is guided to output through the wall A of the side. In this way, the air after heat exchange can be transported to the indoor by using the wall A of the side of the shell 1 on both sides to be inclined downward, and the wall A on both sides can guide the air to be transported to the lower space of the indoor quickly to realize the rapid adjustment of the temperature in the indoor.

[0065] At the same time, the air output by the second air outlet 122 on the baffle 1011 is guided to output through the wall B of the top. The air flowing along the wall B of the top can be transported in a large span in a diagonal direction in the indoor, and then the air after heat exchange can be transmitted at a long distance to make the temperature distribution in the indoor more uniform.

[0066] Preferably, the indoor fan is a centrifugal fan, the centrifugal fan is provided with an outlet for air outlet in the circumferential direction, one end surface of the centrifugal fan is provided with an inlet for air inlet, and the inlet of the centrifugal fan faces the air inlet 11. Under the action of the centrifugal fan, the heat-exchanged air can be simultaneously delivered to the three air outlets 12 to meet the purpose of uniform air distribution. In the preferred design, a deflector 13 is further arranged in the air outlet 12, and the deflector is used to guide the air output from the air outlet 12. The deflector 13 can rotate to adjust the included angle between the air flow direction output from the air outlet 12 and the wall to meet different air supply requirements.

[0067] In some embodiments, in order to meet the mutual influence of air inlet and air outlet in the shell 1, for example, an air inlet channel can be arranged between the inlet of the centrifugal fan and the air inlet 11, and the indoor heat exchanger is arranged in the air inlet channel.

[0068] Alternatively, an air guide cover 4 can be arranged in the shell 1, the air guide cover 4 is used to guide the air flow output from the outlet of the centrifugal fan to the air outlet 12. The air output from the outlet of the centrifugal fan will be guided into each air outlet 12 through the air guide cover 4. Among them, the middle part of the air guide cover 4 is provided with a first air vent 41, the two sides of the air guide cover 4 are respectively provided with a second air vent 42, and a wind-blocking coaming 43 is further arranged on the air guide cover 4, the wind-blocking coaming is arranged around the first air vent 41 and located between the two second air vents 42; the first air vent 41 is connected with the air inlet 11, the indoor heat exchanger is arranged in the wind-blocking coaming, and the second air vent 42 is connected with the first air outlet 121 on the corresponding side.

[0069] The air introduced from the air inlet 11 enters the centrifugal fan after being heat-exchanged with the indoor heat exchanger through the first air vent 41, and the heat-exchanged air output from the centrifugal fan, part of the heat-exchanged air is directly output through the second air outlet 122, and another part of the heat-exchanged air is output from the first air outlet 121 after being reversed through the second air vent 42. The heat-exchanged air output from the first air outlet 121 is separated from the first air vent 41 by the wind-blocking coaming, so that the mutual influence of air inlet and air outlet can be avoided.

[0070] In order to increase the heat exchange area, the indoor heat exchanger is arranged inclined relative to the air guide cover 4, and a drain hole (not labeled) is arranged at the bottom of the wind-blocking coaming, and a drain pipe (not labeled) extending to the outside of the shell 1 is connected to the drain hole.

[0071] In some embodiments, the first baffle 1011 can be provided with a first baffle edge 1012 on both sides of the baffle 1011, the height of the first baffle edge gradually decreases in the direction away from the baffle 1011; the panel 102 is provided with a second baffle edge 1021 on the outside of the first air outlet 121, the height of the second baffle edge gradually increases in the direction away from the baffle 1011; the first baffle and the second baffle edge on the same side are connected together. After the first baffle edge and the second baffle edge are connected together, the first baffle edge, the second baffle edge and the baffle 1011 together form the side wall of the shell 1.

[0072] In order to reduce the mutual influence of the air inlet and outlet on the outside of the shell 1, the air inlet 11 needs to be inclined towards the ground direction of the indoor. Therefore, the overall thickness of the shell 1 gradually decreases in the air outlet direction of the second air outlet 122; the back plate 101 is used to abut against the wall installation of the top surface of the indoor, the first air outlet 121 is parallel to the wall of the side surface of the indoor on the corresponding side, and the second air outlet 122 is parallel to the wall of the top surface of the indoor. The angle between the air outlet direction of the air outlet 12 and the air inlet direction of the air inlet 11 will be less than 180 degrees. On the one hand, it can avoid the output of the heat exchange air being directly sucked into the air inlet 11, and on the other hand, it can make the heat exchange air output to the indoor change temperature and flow more quickly towards the air inlet 11, so as to make the air circulation angle smaller and the air resistance smaller to improve the energy efficiency.

[0073] Further, in order to facilitate the installation of the indoor unit in the user's home, the air conditioner further comprises a mounting bracket 5; the mounting bracket 5 is used to be fixedly installed at the corner position of the indoor wall; correspondingly, the back plate of the shell 1 is provided with a hanging rack 6, and the hanging rack 6 is installed on the mounting bracket 5. Specifically, when installed in the user's home, the mounting bracket 5 is fixedly installed at the corner position of the indoor wall, and the mounting bracket 5 is fixedly installed on the wall of the top surface, and then the hanging rack 6 on the shell 1 is hung on the mounting bracket 5.

[0074] The mounting bracket 5 is fixedly installed on the wall of the top surface by using an expansion bolt, and correspondingly, the mounting bracket 5 is provided with a connecting plate 501 arranged parallel to the wall of the top surface. When the mounting bracket 5 is fixedly installed, the connecting plate 501 is abutted against the wall of the top surface, and then fixedly installed by the expansion bolt.

[0075] In addition, to facilitate hanging the outer casing 1 on the mounting bracket 5, the mounting bracket 5 is provided with a first support portion 51 and a second support portion 52 arranged vertically. The hanger 6 includes an overlapping portion 61 and a snap-fit ​​portion 62 arranged vertically. The overlapping portion 61 rests on the first support portion 51, and the snap-fit ​​portion 62 snaps onto the second support portion 52. After the mounting bracket 5 is fixed to the wall on the top surface, the outer casing 1 is supported by the overlapping portion 61 cooperating with the first support portion 51; at the same time, the snap-fit ​​portion 62 cooperates with the second support portion 52, which satisfies both the requirement of supporting the outer casing 1 and the requirement of positioning it through the snap-fit ​​portion 62.

[0076] The first supporting part 51 can be a flanged structure set on the top of the mounting bracket 5, and the second supporting part 52 is a supporting plate set on the lower part of the mounting bracket 5; the overlapping part 61 is an overlapping bracket set on the top of the back plate of the outer shell 1, and the snap-fit ​​part 62 is a snap-fit ​​bracket set on the back plate of the outer shell 1. During assembly, the overlapping bracket is first placed on the flanged structure, then the position of the outer shell 1 is adjusted so that the snap-fit ​​bracket is placed on the supporting plate, and finally, the entire outer shell 1 is moved toward the supporting plate so that the snap-fit ​​bracket is snapped onto the supporting plate.

[0077] Example 3

[0078] like Figures 8-13 As shown, based on the above embodiment one, the difference is that: the outer shell 1 is used to be installed at an inclined position in the corner of the indoor wall, the panel 102 of the outer shell 1 is provided with an air inlet 11, and the side wall 103 of the outer shell 1 is provided with an air outlet 12 for sending air out along the indoor wall.

[0079] The outer casing 1 has an inverted triangular structure, and air outlets 12 are respectively provided on the top and sides of the side walls 103 of the outer casing 1. The inverted triangular structure of the outer casing 1 allows the indoor unit to be arranged at an angle in the corner of the room, and it also allows the air outlets 12 on the three side walls 103 to be closer to the corresponding side walls, so that the air output from the air outlets 12 can flow along the walls.

[0080] In addition, for the air outlets 12 at different positions on the side wall 103, the air outlet 12 located at the top of the side wall 103 of the housing 1 is used to send air out along the wall of the ceiling of the room, and the air outlet 12 located on the side of the side wall 103 of the housing 1 is used to send air out along the side wall of the room.

[0081] In actual use, the air output from the air outlets 12 located on both sides of the side wall 103 is guided out by the side walls A. In this way, the side walls A on both sides of the outer casing 1 can be used to deliver the heat-exchanged air into the room at an angle downwards. The side walls A can guide the air to be quickly delivered to the lower part of the room to achieve rapid adjustment of the room temperature.

[0082] At the same time, the air output from the air outlet 12 at the top of the side wall 103 is guided to be output due to the top wall B. The air flowing along the top wall B can be transported in a diagonal direction with a large span in the room, and the air after heat exchange can be transmitted at a long distance, so that the temperature distribution in the room is more uniform.

[0083] Since the angle between the air output direction of the air outlet 12 and the air inlet direction of the air inlet 11 will be less than 180 degrees, on the one hand, the output heat exchange air is avoided to be directly sucked into the air inlet 11, and on the other hand, the heat exchange air output to the room changes the temperature, and the flow direction is reversed to the air inlet 11 more quickly, so that the air circulation angle is small, the air resistance is small, and the energy efficiency is improved.

[0084] In a preferred embodiment, the indoor fan uses a centrifugal fan, the centrifugal fan has an outlet for air outlet distributed in the circumferential direction, one end surface of the centrifugal fan is provided with an inlet for air inlet, and the inlet of the centrifugal fan faces the air inlet 11. Under the action of the centrifugal fan, the air after heat exchange can be transported to the three air outlets 12 at the same time to meet the purpose of uniform distribution of air volume. In a preferred design, a guide plate is further arranged in the air outlet 12, and the guide plate is used to guide the air output from the air outlet 12. The guide plate can rotate to adjust the included angle between the air flow direction of the air outlet 12 and the wall, so as to meet different air supply requirements.

[0085] In some embodiments, in order to meet the mutual influence of the air inlet and outlet in the shell 1, for example, an air inlet cover plate 4' can be arranged between the inlet of the centrifugal fan and the air inlet 11, and the air inlet cover plate 4' is provided with a ventilation opening 40'; the air inlet cover plate 4' is arranged in the shell 1 and forms an air inlet cavity between the air inlet cover plate 4' and the panel of the shell 1, and the indoor heat exchanger is located in the air inlet cavity. During the air inlet and outlet process, the air entering the shell 1 from the air inlet 11 first enters the air inlet cavity and exchanges heat with the indoor heat exchanger, and the air after heat exchange is distributed and transported to each air outlet 12 under the action of the centrifugal fan, so as to avoid the mutual interference of the air inlet and outlet in the shell 1.

[0086] Further, in order to facilitate the installation of the indoor unit in the user's home, the air conditioner further comprises a mounting bracket 5; the mounting bracket 5 is a inverted triangular frame body, the top of the mounting bracket 5 is used for fixing and mounting on the top wall in the room, and the side of the mounting bracket 5 is used for fixing and mounting on the side wall in the room; correspondingly, the back plate of the shell 1 is provided with a hanging bracket 6, and the hanging bracket 6 is mounted on the mounting bracket 5. Specifically, when installed in the user's home, the three edges of the mounting bracket 5 are respectively fixed and mounted on different walls in the room, and then the hanging bracket 6 on the shell 1 is hung on the mounting bracket 5.

[0087] The mounting bracket 5 is fixed on the wall of the ceiling by expansion bolts, and three edges of the mounting bracket 5 are provided with connecting plates 501 which are parallel to the wall surface.

[0088] In addition, the mounting bracket 5 is provided with a first bearing part 51 and a second bearing part 52 arranged in sequence, and the hanging bracket 6 comprises a lapping part 61 and a clamping part 62 arranged in sequence, the lapping part 61 is lapped on the first bearing part 51, and the clamping part 62 is clamped on the second bearing part 52. After the mounting bracket 5 is fixed on the wall of the ceiling, the shell 1 is supported by the lapping part 61 and the first bearing part 51, and the clamping part 62 and the second bearing part 52 cooperate, which meets the requirements of supporting the shell 1 and positioning by the clamping part 62.

[0089] The first bearing part 51 can be a flange structure arranged on the top of the mounting bracket 5, and the second bearing part 52 can be a bearing plate arranged on the lower part of the mounting bracket 5. The lapping part 61 can be a lapping frame arranged on the top of the back plate of the shell 1, and the clamping part 62 can be a clamping frame arranged on the back plate of the shell 1. During assembly, the lapping frame is lapped on the flange structure, the position of the shell 1 is adjusted so that the clamping frame is lapped on the bearing plate, and finally the shell 1 is moved towards the bearing plate so that the clamping frame is clamped on the bearing plate.

[0090] The shell 1 can be a triangular structure, and in some embodiments, as shown in Figure 13 The area of the panel 102 of the shell 1 is smaller than that of the back plate 101, and the side wall 103 is arranged obliquely between the panel 102 and the back plate 101. Because the side wall 103 is arranged obliquely relative to the panel 102 and the back plate 101, the air outlet 12 on the side wall 103 can be arranged more parallel to the wall, so that the air output from the air outlet 12 can be transported along the wall for a long distance more effectively.

[0091] Embodiment Four

[0092] Based on the above embodiments one to three, the specific control method of the air conditioner during operation is that the heat exchange air output from the air outlet of the air conditioner flows along the wall of the indoor.

[0093] The air outputted from the air outlet of the air conditioner forms an air curtain on the surface of the wall during flowing along the wall, which can effectively regulate the temperature of the wall to achieve effective temperature insulation between the indoor and outdoor. The problem that the temperature of the indoor area close to the wall is greatly affected by the outdoor temperature and the temperature distribution in different areas of the indoor is uneven is overcome.

[0094] Meanwhile, the heat exchange air outputted from the air outlet of the air conditioner forms an air curtain on the surface of the wall during flowing along the wall, which can effectively extend the distance of the air transmission in the indoor by the air curtain effect, thereby achieving more uniform regulation of the temperature in the indoor.

[0095] According to different seasons, the air conditioner usually includes a heating mode and a cooling mode. In the heating mode or the cooling mode, the air outlet quantity and the air outlet angle of different air outlets can be further adjusted to optimize the temperature regulation efficiency and effect.

[0096] In the heating mode, the hot air outputted from the air conditioner is light and easy to rise and accumulate in the upper area of the indoor. Therefore, the air outlet quantity of the two side air outlets is increased, and the air outlet quantity of the top air outlet is decreased. In this way, the hot air outputted from the air conditioner can effectively flow downward along the side wall to flow to the lower space of the indoor.

[0097] At the same time, in the heating mode, the air outlet direction of the air conditioner can be controlled to flow along the wall of the indoor and blow to the indoor side. In this way, the hot air can quickly spread to the indoor side during flowing to reduce the influence of the hot air rising on the hot air transmission. Especially for the hot air outputted from the top air outlet, the hot air can effectively flow along the top wall while increasing the downward flow trend of the hot air. For the hot air outputted from the two side air outlets, the hot air can quickly spread to the indoor side while flowing downward to improve the temperature distribution uniformity.

[0098] In the cooling mode, the cold air outputted from the air conditioner is heavy and easy to sink and accumulate in the lower area of the indoor. Therefore, the air outlet quantity of the two side air outlets is decreased, and the air outlet quantity of the top air outlet is increased. In this way, the cold air outputted from the air conditioner can be effectively transported at a long distance along the top wall, and the cold air can automatically sink during flowing to uniformly cool the indoor.

[0099] Similarly, in the cooling mode, the air outlet direction of the air conditioner can also be controlled to blow along the wall of the room and towards the outside of the room. In this way, the cold air can be transmitted along the wall for a longer distance during the flow. Especially for the cold air output from the top air outlet, it can effectively cross the room diagonally so that the cold quantity is evenly distributed to each area of the room to improve the temperature distribution uniformity.

[0100] In the description of the above embodiments, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0101] The above merely describes specific implementations of the present application, but the protection scope of the present application is not limited thereto, and any changes or replacements easily thought of by those skilled in the art within the technical scope disclosed by the present application shall be encompassed within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
