The invention provides an air conditioner which can be a wall-mounted air conditioner, a cabinet or an integrated machine.

In an embodiment of the present invention, please refer to fig. 1 to 4 in combination, an air conditioner includes:

the shell 10 is provided with a heat exchange air duct 11, a heat exchange air inlet 12 and a heat exchange air outlet 13 which are respectively communicated with the heat exchange air duct 11;

the indoor heat exchanger 20 is arranged in the heat exchange air duct 11;

the heat exchange wind wheel 30 is arranged in the heat exchange air duct 11; the method comprises the steps of,

the drainage module 40 is installed on the shell 10 and is arranged near the top of the shell 10, the drainage module 40 is located on the air inlet side of the indoor heat exchanger 20, the drainage module 40 comprises a shell 41 formed with a drainage air duct 42 and a drainage wind wheel 43 located in the drainage air duct 42, the drainage module 40 at least has a first state, and in the first state, air flow blown out of the drainage air duct 42 avoids the indoor heat exchanger 20.

In an embodiment, the air conditioner is a wall-mounted air conditioner, the housing 10 is generally in a strip shape extending along a left-right direction, the heat exchange air inlet 12 is disposed on a top surface of the housing 10, and the heat exchange air outlet 13 is disposed on a front lower side of the housing 10, so that the air conditioner is blown out from the top to the bottom. In addition, the indoor heat exchanger 20 extends in the length direction of the casing 10, and the indoor heat exchanger 20 has an inverted V shape. In addition, the heat exchange air inlet 12 may be disposed at an end (i.e., a left end and/or a right end) of the housing 10, and the heat exchange air outlet 13 may be disposed at an end as well. Specifically, the indoor air enters the heat exchange air duct 11 through the heat exchange air inlet 12, and after heat exchange is performed by the indoor heat exchanger 20, the indoor air is blown out from the heat exchange air outlet 13 under the action of the heat exchange wind wheel 30, and the air blown out from the heat exchange air outlet 13 is warm air or cold air.

In the embodiment of the invention, the drainage module 40 is an independent wind wheel unit, does not comprise a heat exchanger, plays a role in indoor air blowing, and improves indoor air circulation. Specifically, in the first state, the indoor air enters the air guide duct 42 and is blown out under the action of the air guide wind wheel 43, and the air blown out from the air guide wind wheel 43 is normal temperature air, that is, the air guide module 40 plays a role in circulating air, and does not cool or heat the indoor air.

In an embodiment, the housing 10 and the casing 41 of the drainage module 40 are connected and integrally formed, so that no additional connection structure is needed between the housing 10 and the casing 41 for connection, and an installation step can be omitted. In one embodiment, the housing 10 and the shell 41 are two separate components and are formed separately, i.e., the housing 10 and the shell 41 are configured separately. In one embodiment, the housing 10 and the shell 41 may be fastened by a fastener or a screw. In one embodiment, the housing 41 is movably connected to the casing 10, for example, the housing 41 is rotatably connected to the casing 10 through a rotation shaft, or the housing 41 is slidably connected to the casing 10.

In this embodiment, the drainage module 40 is disposed near the top of the casing 10, and on the air inlet side of the indoor heat exchanger 20, that is, the air entering the drainage module 40 is not the air flow after heat exchange of the indoor heat exchanger 20. The presence of the flow directing module 40 near the top of the housing 10 and on the air intake side of the indoor heat exchanger 20 indicates that the air flow blown by the flow directing module 40 is above the heat exchange air outlet 13.

When the air conditioner heats, hot air flows easily rise after being separated from the air duct mouth because the density of the hot air is small, and the hot air is difficult to be delivered to the ground; when in refrigeration, the cold air density is high, the cold air is easy to sink, the room temperature is unevenly distributed, the phenomenon of head heating and foot cooling occurs, and the comfort is poor. In the invention, the drainage module 40 is arranged, so that the drainage module 40 can circulate the indoor air in the first state and has a disturbance effect on the indoor air. Specifically, referring to fig. 3, when the air conditioner heats, the heat exchange air outlet 13 blows out the hot air flow, the drainage module 40 blows out the indoor air with a temperature lower than the hot air flow, and the drainage module 40 is located above the heat exchange air outlet 13, so that the indoor air blown out by the drainage module 40 plays a role of pressing down the hot air flow, thereby reducing the rise of the hot air flow. Referring to fig. 2, when the air conditioner performs cooling, the heat exchange air outlet 13 blows out cold air flow, the drainage module 40 blows out indoor air with a temperature higher than that of the cold air flow, and the indoor air blown out by the drainage module 40 can stir the cold air flow, so that the cold air flow is more dispersed, concentrated blowing out of the cold air flow is avoided, and the indoor air blown out by the drainage module 40 can also drive part of the cold air flow to rise, so that sinking of the cold air flow is reduced. Therefore, by arranging the drainage module 40, the normal-temperature air flow generated by the drainage module 40 collides with and convects with the cold-hot air flow generated by the heat exchange air duct 11, the cold-hot air flow can be guided in the horizontal or vertical direction, the effects of disturbing indoor air flow and improving temperature layering are achieved, the indoor air flow is more facilitated to be generated, and indoor temperature distribution is more uniform.

Referring to fig. 4, in the no-wind-sensation mode, the air deflector 50 covers the heat exchange air outlet 13, the drainage module 40 is in the first state, and the normal-temperature air flow blown out by the drainage module 40 can further disturb the air flow blown out by the heat exchange air outlet 13, so as to enhance no-wind-sensation.

In the embodiment of the present invention, the drainage module 40 may be disposed inside the housing 10 or outside the housing 10, please refer to fig. 1 to 14 in combination, in an embodiment, the drainage module 40 is disposed inside the housing 10, the housing 10 is provided with the normal temperature air outlet 14, in the first state, the air outlet end of the drainage air duct 42 is communicated with the normal temperature air outlet 14, and the air inlet end of the drainage air duct 42 is communicated with the heat exchange air inlet 12. In this embodiment, the drainage air duct 42 and the heat exchange air duct 11 share an air inlet, so that the air inlet is not required to be additionally formed on the housing 10, which is beneficial to simplifying the overall structure. In addition, a normal temperature air inlet can be formed in the casing 10, and the air inlet end of the drainage air duct 42 is communicated with the normal temperature air inlet. Specifically, in the first state, the air flow entering from the heat exchange air inlet 12 is divided into two flows, one of the two flows to the heat exchange air duct 11, and the two flows are blown out from the heat exchange air outlet 13 after heat exchange of the indoor heat exchanger 20; the other air flow flows to the drainage air duct 42, and the normal-temperature air outlet 14 blows out normal-temperature air.

In one embodiment, the housing 10 includes a front panel 15, where the front panel 15 refers to a plate body that faces the user and extends in an up-down direction, and for wall-mounted devices, the front panel 15 is the plate body opposite the wall-mounted panel. In this embodiment, the normal temperature air outlet 14 is provided on the front panel 15, so that the drainage module 40 is blown forward, so that the effect on the heat exchange air outlet 13 below the drainage module is better, and the influence on the user is smaller when the air blown out by the drainage module 40 is blown forward because the air flow blown out by the drainage module is normal temperature air flow. Optionally, the normal temperature air outlet 14 is disposed near the upper end of the front panel 15, and the air flow blown by the drainage module 40 is far higher than that of the user, so that direct blowing can be avoided. In one embodiment, the normal temperature air outlet 14 extends along the length direction of the casing 10 to be in a strip shape, so that the normal temperature air flow blown out through the normal temperature air outlet 14 is more dispersed, and the application range is wider; when the heat exchange air outlet 13 extends along the length direction of the shell 10 to be long, the action range of the air flow blown out by the long normal-temperature air outlet 14 on the air flow blown out by the heat exchange air outlet 13 positioned below the long normal-temperature air outlet is larger, and the effect is better.

In one embodiment, the drain module 40 is located between the indoor heat exchanger 20 and the front panel 15. Generally, the indoor heat exchanger 20 disposed in the air conditioner is in an inverted V shape or other bent shape, so that the interval between the position of the indoor heat exchanger 20 near the top and the front panel 15 is large, and thus the disposition of the drainage module 40 at the large interval can facilitate the disposition of the drainage module 40. And, setting up drainage module 40 here can make things convenient for drainage module 40 and heat transfer air intake 12 and normal atmospheric temperature air outlet 14 intercommunication. Of course, the drainage module 40 may also be located above the indoor heat exchanger 20.

In one embodiment, the normal temperature air outlet 14 is provided with an air door 16, and the air door 16 can cover and open the normal temperature air outlet 14. In this embodiment, the damper 16 may be rotatably or slidably connected to the housing 10 to cover and uncover the ambient temperature air outlet 14. By providing the damper 16, the normal temperature air outlet 14 can be controlled to be opened or closed as required, for example, when turbulence is not required, the normal temperature air outlet 14 is closed, and the air conditioner only blows cold and warm air flow; when the turbulence is needed to reduce the uncomfortable feeling of the cold and warm air flow, the normal temperature air outlet 14 can be opened, and the air conditioner can blow out the normal temperature air flow and the cold and warm air flow at the same time. In addition, an air outlet grille can be arranged at the normal temperature air outlet 14.

Referring to fig. 5 and 6 in combination, in one embodiment, the damper 16 is rotatably connected to the housing 10 through a rotation shaft, and a side of the casing 41 close to the rotation shaft is spaced from an inner surface of the housing 10, so that the damper 16 can rotate in the housing 10 to cover a space between the casing 41 and the housing 10 to form a drainage duct 42 together with the casing 41. In this embodiment, the part corresponding to the position of the housing 41 is missing, for example, the volute part of the housing 41 is missing, so that a gap 17 exists between the housing 41 and the casing 10, and after the air door 16 rotates inwards, the gap 17 can be filled, so that the air guiding duct 42 becomes complete, and normal air outlet is realized. In order to reduce the air-out resistance, in this embodiment, when the damper 16 rotates inwards to cover the interval between the housing 41 and the casing 10, the damper 16 and the housing 41 are in smooth transition, i.e. form a complete curve therebetween, so that the uneven phenomenon of the finally formed drainage duct 42 can be avoided. In fig. 6, the air door 16 covers the notch 17, and the air conditioner is shown in the air-out mode without air feeling, and in the cooling or heating mode, the air door 16 also covers the notch 17, and the air deflector 50 is opened.

Referring to fig. 15 to 17, in an embodiment, the drainage module 40 is located outside the housing 10, so that the housing 10 does not need to be provided with an additional normal temperature air outlet 14, and the air blown by the drainage module 40 does not pass through the housing 10. In this embodiment, the drainage module 40 is located on the top surface of the housing 10, and for other positions of the housing 10, the drainage module 40 can be hidden in a dead angle of the user's sight, so as to avoid the protrusion of the drainage module 40.

In the embodiment of the present invention, the housing 10 includes a front panel 15 and a top plate (not shown) connected to an upper end of the front panel 15, the top plate extends rearward, and the top plate is provided with a heat exchange air inlet 12, for example, the top plate forms an air inlet grille. In one embodiment, the housing 41 is connected to the front panel 15, and in an embodiment in which the drain module 40 is located within the housing 10, the housing 41 is connected to the inside of the front panel 15. In one embodiment, the housing 41 is connected to the top plate.

In the embodiment of the present invention, the flow guiding module 40 further has a second state, in which the air flow blown by the flow guiding wind wheel 43 flows through the indoor heat exchanger 20, that is, in the second state, the flow guiding wind wheel 43 guides the air flow to the indoor heat exchanger 20, so that the air flow in the heat exchanging air duct 11 is increased, that is, the air flow blown out during cooling or heating of the air conditioner is larger, and the indoor temperature can be quickly reduced or raised. It should be noted that, in the embodiments of the present invention, the descriptions of "first", "second", etc. are referred to for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.

In the first state, the air flow blown out of the drainage wind wheel 43 avoids the indoor heat exchanger 20; in the second state, the air flow blown out by the flow guiding wind wheel 43 flows through the indoor heat exchanger 20. In this embodiment, the drainage module 40 rotates relative to the indoor heat exchanger 20 to switch between the first state and the second state, and when the drainage module 40 rotates, the drainage air duct 42 can rotate by a certain angle, so that the air supply direction of the drainage air duct 42 can be changed, and the air flow blown out from the air outlet end of the drainage air duct 42 directly enters the room or supplements air for the heat exchange air inlet 12. In this embodiment, a motor is disposed in the housing 10 to drive the drainage module 40, so that the drainage module 40 can rotate.

In the embodiment of the present invention, there are various situations where the drainage module 40 is rotationally connected to the housing 10, please refer to fig. 7 to 9 in combination, in an embodiment, only the housing 41 of the drainage module 40 rotates to change the direction of the incoming and outgoing air, specifically, the drainage wind wheel 43 is installed on the housing 10, the housing 41 is rotationally connected to the housing 10, and the housing 41 and the drainage wind wheel 43 rotate independently. That is, in this embodiment, the drainage wind wheel 43 does not rotate when the housing 41 rotates, and the rotation of the drainage wind wheel are independent of each other and do not affect each other.

In the following description, the drainage wind wheel 43 is taken as a cross-flow wind wheel, in an embodiment, the drainage wind wheel 43 is a cross-flow wind wheel, the casing 41 rotates with the axis of the cross-flow wind wheel as a shaft, and thus, the positions of the air inlet end and the air outlet end of the drainage air duct 42 are changed along with the rotation of the casing 41. Optionally, the cross-flow rotor extends in a lateral direction, i.e. in the case of wall-mounted machines, along the length of the housing 10. In the embodiment in which the drainage wind wheel 43 is installed in the casing 10, referring to fig. 9, in the first state, the air outlet end of the drainage wind channel 42 faces the normal temperature air outlet 14, the air inlet end of the drainage wind channel 42 faces the heat exchange air inlet 12, and indoor air enters the drainage wind channel 42 from the heat exchange air inlet 12 and is blown out from the normal temperature air outlet 14 on the front side; referring to fig. 8, in the second state, the air outlet end of the air guiding duct 42 faces downward and is staggered from the normal temperature air outlet 14, the air inlet end of the air guiding duct 42 is still within the coverage area of the heat exchanging air inlet 12, i.e. faces the heat exchanging air inlet 12, and the indoor air enters the air guiding duct 42 from the heat exchanging air inlet 12, is blown out downward by the air guiding duct 42, and then passes through the indoor heat exchanger 20 for heat exchanging.

In the embodiment in which the drainage wind wheel 43 is mounted outside the housing 10 and is located on the top surface of the housing 10, in the first state, the air outlet end of the drainage wind channel 42 faces forward, and the air inlet end faces upward; in the second state, the air outlet end of the drainage air duct 42 faces the heat exchange air inlet 12, and the air inlet end of the drainage air duct 42 faces upwards. In addition, in other embodiments, the drainage wind wheel 43 may also be a centrifugal wind wheel.

In this embodiment, the axis of the drainage wind wheel 43 is changed when switching between the first state and the second state.

In the following description, the flow guiding wind wheel 43 is taken as an axial flow wind wheel as an example, in one embodiment, in the first state, the axis of the flow guiding wind wheel 43 extends along the front-back direction to realize wind inlet and outlet along the front-back direction; in the second state, the axis of the drainage wind wheel 43 passes through the heat exchange air inlet 12 to realize air inlet and outlet along the up-down direction. Referring to fig. 12 in combination, when the drainage module 40 is located in the housing 10, in the first state, the drainage module 40 is attached to the front panel 15, and the air outlet end of the drainage module 40 is covered at the normal temperature air outlet 14; referring to fig. 11 in combination, in the second state, the flow guiding module 40 rotates upwards until the axis of the flow guiding wind wheel 43 is along the up-down direction, which is equivalent to the rotation angle of the flow guiding module 40 being 90 ° when the first state is switched to the second state. Of course, in other embodiments, the rotation angle of the drainage module 40 may be greater or less than 90 °. Referring to fig. 17 in combination, when the drainage module 40 is located outside the housing 10, in the first state, the drainage module 40 is erected above the top plate, and air is blown out from the rear toward the front; referring to fig. 16 in combination, in the second state, the drainage module 40 lies on the top plate and discharges air from top to bottom. In addition, in this embodiment, the drainage wind wheel 43 may be a cross-flow wind wheel or a centrifugal wind wheel.

Referring to fig. 13 and 14 in combination, in order to achieve that the drainage module 40 has a first state and a second state, in an embodiment, the drainage module 40 is located in the housing 10, the drainage wind wheel 43 is an axial flow wind wheel, and the driving motor of the drainage module 40 drives the drainage wind wheel 43 to rotate along a first direction, so that the drainage module 40 has the first state (as shown in fig. 14); the driving motor drives the flow guiding wind wheel 43 to rotate in a direction opposite to the first direction, so that the flow guiding module 40 has a second state (as shown in fig. 13), and in the second state, the air flow blown by the flow guiding wind wheel 43 flows through the indoor heat exchanger 20. In this embodiment, the air outlet end of the air guiding duct 42 is covered at the normal temperature air outlet 14, and in the first state, air enters the air guiding duct 42 from the heat exchange air inlet 12 and is blown out from the normal temperature air outlet 14, so as to realize turbulence of the air; in the second state, the rotation directions of the axial flow wind wheels are opposite, so that the air inlet and outlet directions of the air are opposite, namely, the air enters the drainage air duct 42 from the normal temperature air outlet 14, and the downward pressure is high when the air enters the upper heat exchange air inlet 12, so that the air blown out of the drainage air duct 42 can be driven to move downwards to jointly pass through the indoor heat exchanger 20, and in the second state, the drainage module 40 can supplement the air to the heat exchange air inlet 12. In this embodiment, the flow guiding wind wheel 43 is controlled to rotate in the forward and reverse directions, so that the flow guiding module 40 is switched between the first state and the second state, which is equivalent to rotating the flow guiding module 40, and the installation between the flow guiding module 40 and the housing 10 can be simplified.

In an embodiment, the heat exchange air outlet 13 is provided with an air deflector 50, the air deflector 50 can cover and open the heat exchange air outlet 13, and a plurality of air dispersing holes are formed in the air deflector 50. When the air deflector 50 covers the heat exchange air outlet 13, air flows are blown out from all the air dispersing holes, and the air dispersing holes disperse the air flows, so that the air conditioner realizes air outlet without wind sensation. When the air deflector 50 opens the heat exchange air outlet 13, air flow is directly blown out from the heat exchange air outlet 13, so that normal air outlet is realized.

In the above, when in the no-wind-sensation mode, since the drainage module 40 is additionally arranged, when the drainage module 40 is in the first state, the drainage module 40 can realize the turbulence effect, further enhance no wind sensation, and when the drainage module 40 is arranged in the shell 10, the air pressure inside the shell 10 can be reduced by the arrangement of the normal-temperature air outlet 14, the pressure relief effect is achieved, and the excessive air pressure in the heat exchange air duct 11 caused by the smaller air output of the heat exchange air outlet 13 is avoided. In the non-wind-sensation-free mode, and when the drainage module 40 is in the second state, the drainage module 40 can timely supplement wind for the heat exchange air inlet 12, so that the air return area is increased.

The foregoing description of the preferred embodiments of the present invention should not be construed as limiting the scope of the invention, but rather should be understood to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the following description and drawings or any application directly or indirectly to other relevant art(s).
