The embodiment of the utility model provides a wall-mounted air conditioner indoor unit. An indoor unit of a wall-mounted type air conditioner is an indoor part of a split wall-mounted type room air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, and the like.

Fig. 1 is a schematic structural view of a wall-mounted type air conditioning indoor unit according to an embodiment of the present invention; fig. 2 is a schematic cross-sectional enlarged view of the wall-mounted air conditioning indoor unit shown in fig. 1; fig. 3 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 when the flow divider 30 opens the first blowing port 11. For the sake of clarity, fig. 1 shows only the structure of the whole of the wall-mounted air conditioning indoor unit, and does not show the ventilation holes of the flow divider 30.

As shown in fig. 1 to 3, a wall-mounted type air conditioning indoor unit according to an embodiment of the present invention may generally include a cabinet 10 and a flow dividing member 30.

The casing 10 has a first blowing port 11. The cabinet 10 is intended to be hung on an indoor wall. The first air blowing port 11 is used for blowing an air flow in the casing 10 into the room to condition the indoor air. The air flow can be cold air produced by the wall-mounted air conditioner indoor unit in a refrigeration mode, hot air produced in a heating mode, or fresh air introduced in a fresh air mode, and the like.

For example, in an alternative configuration, as shown in fig. 1, the housing 10 is elongated in a horizontal direction, and the transverse or longitudinal direction of the housing 10 is indicated by x in the figure. Of course, in some alternative embodiments, the casing 10 may also be made to have other shapes such as a circle, a square, etc., and will not be described herein again.

The wall-mounted air conditioner indoor unit may be an indoor unit of an air conditioner that performs cooling/heating through a vapor compression refrigeration cycle system, and further includes a heat exchanger 40 and a cross-flow fan 50. The heat exchanger 40 is disposed in the casing 10, and is configured to exchange heat with an air flow flowing through the casing to form a heat exchange air flow, i.e., a cold air or a hot air, which may be a three-stage fin heat exchanger. The cross-flow fan 50 is disposed in the casing 10, and is configured to cause indoor air to enter the casing 10 through the air inlet 13 at the top of the casing 10, to complete heat exchange with the heat exchanger 40 to form heat exchange air flow, and then to cause the heat exchange air flow to flow through the air duct 20 to the first air supply outlet 11, and finally to be blown into the room from the first air supply outlet 11.

The flow divider 30 is disposed outside the first air blowing port 11 at an interval from the first air blowing port 11, so that the air flow from the first air blowing port 11 is blown toward the flow divider 30 and then divergently blown toward the edge of the flow divider 30 toward the indoor environment under the guidance of the surface of the flow divider 30. For example, in the embodiment shown in fig. 1 to 3, the first air blowing opening 11 is elongated with a length direction parallel to the length direction x of the casing 10, and the flow divider 30 is rod-shaped with a length direction parallel to the first air blowing opening 11. At this time, the outlet airflow is guided by the surface of the flow divider 30 and blown out toward both sides in the width direction (y direction) of the flow divider 30, that is, both sides in the width direction of the first air blowing port 11. More specifically, when the first air blowing port 11 is opened on the front side of the casing 10, the air flow is divided into two sub-flows, which are blown upward and downward, respectively, guided by the surface of the flow divider 30. The upward blown air flow is upward flowing and is used for long-distance air supply; the downward blowing airflow sinks and flows for short-distance air supply. The far and near air flows supply air, so that the air supply range is expanded. Of course, if the first air outlet 11 is circular or square, the flow divider 30 may be correspondingly circular or square, so that the outlet air flows outwards along the radial direction of the flow divider 30.

In the embodiment of the present invention, after flowing out from the first air supply outlet 11, the outlet air flow is blown to the indoor environment, rather than directly blown to the indoor environment, and is blown to the flow dividing member 30 under the guidance of the surface of the flow dividing member 30 so as to be divergently blown to the indoor environment toward the edge of the flow dividing member 30, so that the outlet air flow is more dispersed, the diffusion range is larger, the indoor cooling/heating speed is faster, the temperature change at each position in the room is more uniform, and the temperature difference is smaller. The air outlet flow can not blow human body forcibly after being dispersed and blown out, and is closer to natural wind, so that people feel more comfortable.

The existing wall-mounted air conditioner indoor unit can better increase the air supply distance or enhance the direction guidance of the air outlet flow by more improving the direction, so that the air outlet flow is blown to a set area to achieve the aim of avoiding human bodies. The idea is creatively changed in the embodiment, the air outlet airflow is just blown out of the first air supply opening 11, so that the air outlet airflow is diffused towards a plurality of directions (at least 2 directions), and the forward direct blowing of powerful airflow is avoided, so that the human body can be avoided, the cold/heat diffusion range is wider, and the indoor temperature difference is reduced. In addition, in the embodiment, the flow divider 30 replaces a conventional air deflector, and by dividing the flow, the flow velocity of the air flow is reduced, thereby avoiding that the air deflector and the surface of the casing 10 are not sufficiently cooled due to too high flow velocity, and the condensation occurs due to uneven temperature distribution. In addition, the shunt member 30 may be surface treated to increase the hydrophobic function of the surface and further prevent the surface from generating condensation.

The inventor finds that, because the flow divider 30 is located at the first air supply outlet 11, when the air conditioner is used for cooling, the temperature is low because the flow divider is directly blown by cold air, and water vapor in the air is easy to be condensed on the surface of the flow divider, so that condensation is generated. Further, the cold air flows out through the edge of the flow divider 30, but no air flow blows over the outer surface 31 of the flow divider 30 and the area adjacent thereto, and a vortex is easily generated, so that condensation is generated on the outer surface 31 of the flow divider 30.

To this end, in the embodiment of the present invention, as shown in fig. 2 and 3, the flow dividing member 30 has an airflow passage, and the airflow passage penetrates through an inner side surface 32 of the flow dividing member 30 facing the first air blowing opening 11 and an outer side surface 31 facing away from the flow dividing member, so as to allow the outlet airflow to flow to the outer side of the flow dividing member 30 through the airflow passage (fig. 2 illustrates the airflow with hollow arrows). So make the vortex of reposition of redundant personnel 30 lateral surface adjacent area broken up, form the disturbance flow field, and then the lateral surface 31 of reposition of redundant personnel 30 can't effectively constitute, accumulate the condensation, avoid appearing great condensation and drip indoor environment, influence user experience.

And moreover, the air flow channels also output some air outlet flows outwards, so that a breeze air supply effect is achieved, and the human body feels more comfortable.

In some embodiments of the present invention, as shown in fig. 2 and 3, the flow divider 30 may be a solid structure and is provided with a plurality of ventilation micropores 301 penetrating through the inner side surface 32 and the outer side surface 31 thereof, and each ventilation micropore 301 forms one of the aforementioned airflow channels. The open area ratio of the flow splitter 30 (total area of all ventilation pores/flow splitter surface area) is preferably between 30% and 60%. The vent holes are preferably circular holes to facilitate machining. The diameter is preferably less than 1cm, and more preferably less than 0.5cm, to avoid both condensation and excessive gas flow there from affecting the normal flow distribution function of the flow distribution member 30.

In other embodiments of the present invention, the flow divider 30 is a hollow structure, and the inner side 32 of the flow divider is provided with a plurality of air inlet micro holes communicated with the inner space of the flow divider 30, and the outer side 31 of the flow divider 30 is provided with a plurality of air outlet micro holes communicated with the inner space of the flow divider 30. Each air inlet micropore of the flow dividing member 30, one air outlet micropore and the inner space of the flow dividing member 30 form an air flow channel together. Each air inlet micropore and each air outlet micropore can be round holes so as to facilitate processing. The flow-dividing members 30 are preferably arranged uniformly on the outer surface, but may be arranged non-uniformly. The diameters of the air inlet micropores and the air outlet micropores are preferably smaller than 1cm, and further preferably smaller than 0.5cm, and the aperture ratio (the total area of all the holes/the total area of the outer surface of the flow divider) of the flow divider 30 is preferably between 30% and 60%, so that condensation can be avoided, and the flow divider 30 can be prevented from being influenced by excessive air flow flowing out of the flow divider to normally exert the flow dividing function.

In some embodiments, as shown in fig. 2 and 3, the inner side surface 32 of the splitter 30 facing at least the first supply outlet 11 may be convexly curved to facilitate directing the air flow towards the edges of the splitter 30. Specifically, if the inner surface of the flow divider 30 facing the first air blowing opening 11 is a plane, the air flow blown perpendicularly to the surface will turn 90 ° and then spread along the surface to the edge. And this embodiment makes this surface be evagination curved surface, and the air-out air current strikes behind the evagination curved medial surface 32 along medial surface 32 to the edge diffusion again, and the air current turns to and is less than 90, turns to the in-process, and the evagination shape of medial surface 32 makes the direction change relatively more mild, air loss and noise are all littleer.

For example, in the embodiment shown in fig. 2 and 3, the first air blowing opening 11 is elongated in a direction parallel to the longitudinal direction of the casing 10, and the flow dividing member 30 is rod-shaped in a direction parallel to the longitudinal direction of the first air blowing opening 11. The two side surfaces (the inner side surface 32 and the outer side surface 31) of the flow dividing element 30 facing the first air supply outlet 11 and facing away from the first air supply outlet 11 are convex curved surfaces, the joint of the two side surfaces forms two top ends A1 and A2, and the two top ends A1 and A2 can be provided with round corners, so that the outline of the cross section (the section perpendicular to the x axis) of the flow dividing element 30 forms an olive shape. This configuration of the shunt 30 is relatively simple and easy to manufacture, and also provides a more aesthetically pleasing appearance.

Specifically, as shown in fig. 2 and 3, the inner side surface 32 of the flow divider 30 facing the first air blowing port 11 may be formed by joining two circular arc surfaces CA1 and CA2, so that the inner side surface 32, particularly the middle point C thereof, protrudes further outward, thereby enabling the air flow blowing thereto to be divided more evenly to both sides of the point C. The outer side surface 31 back to the first air supply outlet 11 is a section of arc surface, so that the appearance is attractive and the manufacture is convenient. The radiuses R1, R2 and the lengths of the arc surfaces CA1 and CA2 at the two ends of the inner side surface 32 can be further made equal, so that the air flows to the two parts tend to be equal. Of course, the cross-sectional profile of the shunt 30 can also be oval or other irregular shapes, and will not be described in detail herein.

In some alternative embodiments, if the first air supply opening and the splitter are both circular, the convex curved surface may be a spherical crown shape, which is not described herein again.

In some embodiments, the splitter 30 may be configured to be reciprocally movable in a direction toward or away from the first outlet 11 to adjust its distance from the first outlet 11, and the air volume of the first outlet 11 may be adjusted accordingly. It will be appreciated that the closer the splitter 30 is to the first outlet 11, the more the outlet air from the first outlet 11 is blocked and the less the volume of air, but the stronger the diverting action of the splitter 30 on the outlet air flow (which causes the flow to be diverted towards its edge). When the flow divider 30 is farther from the first outlet 11, the air flow from the first outlet 11 is smoother, and the air flow rate is larger, but the turning action on the air flow is weakened.

In some embodiments, as shown in fig. 3, the casing 10 further has an air duct 20 for supplying air to the first air supply outlet 11. The air duct 20 may have a divergent outlet which is connected to the first supply port 11 and whose flow cross section is gradually increased in the air flow direction. That is, the air duct 20 is gradually enlarged near the first air blowing opening 11, and this shape makes the air flow start to spread towards the edge before flowing out of the first air blowing opening 11, which is more beneficial to the spreading and blowing of the outlet air flow.

As shown in fig. 2 and 3, the flow dividing member 30 is configured to be reciprocally movable in a direction approaching or separating from the first blowing port 11 to open or close the first blowing port 11. As shown in fig. 3, the surface contour of the diverging outlet of the air duct 20 matches the surface contour of the corresponding section of the flow divider 30, so that the flow divider 30 is attached to the surface of the diverging outlet of the air duct 20 in the closed state, which enables the flow divider 30 to better seal the first air outlet 11, and prevents foreign matters such as dust from entering the casing 10 through the first air outlet 11. In addition, when the wall-mounted air conditioner indoor unit is in a non-operation state such as power failure or standby state, the flow dividing member 30 is moved to a closed state, the flow dividing member 30 is also inwards embedded into the first air supply outlet 11, and the situation that the appearance of the flow dividing member 30 is completely outside the first air supply outlet 11 is avoided. For example, when the flow divider 30 is olive-shaped, and the inner side surface of the flow divider facing the first air outlet 11 is a convex curved surface, the air outlet section sa is a concave curved surface to match with the convex curved surface.

In some embodiments, as shown in fig. 2 and 3, the first air supply outlet 11 is opened at the front side of the casing 10, and the bottom wall of the casing 10 is opened with the second air supply outlet 12 which is opened downward and connected to the air duct 20. The second supply outlet 12 may be provided with a wind deflector 60. In this way, air can be supplied from the second air supply outlet 12 to the right below the wall-mounted air conditioning indoor unit. The downward air supply in the heating mode is more favorable for accelerating the temperature rising speed of the lower-layer space of the house, so that the human body can feel the heating effect more quickly.

The casing 10 of the present embodiment includes a framework for forming a basic frame of the indoor unit and body components such as a volute and a volute tongue for defining an air outlet duct, and is not a pure air conditioning casing. Specifically, as shown in fig. 2 and 3, the casing 10 includes a volute tongue 21, a volute casing 22, and a separation strip 23 located below the front end of the volute tongue 21 and in front of the lower end of the volute casing 22. The volute tongue 21, the volute 22 and the dividing strip 23 together define an air duct 20. The division bar 23 and the front end of the volute tongue 21 define a first air supply opening 11, and the division bar 23 and the lower end of the volute casing 22 define a second air supply opening 12. It will be understood that the volute tongue 21, the volute 22 and the dividing strip 23 are all long strips extending along the length of the casing 10. A cross flow fan 50 having a length direction parallel to the length direction of the cabinet 10 is installed at an inlet of the air duct 20. The dividing strip 23 is a part of the housing 10, and can be formed integrally with the adjacent housing part.

More specifically, the volute tongue 21 includes an air inlet section (kc), a middle section (cs) and an air outlet section (sa) in sequence from the inlet end to the outlet end thereof. Wherein the air inlet section (kc) extends from the inlet end (k) to the rear lower side. The middle section (cs) extends forward and downward from the end (c) of the air intake section (kc). The air outlet section (sa) extends forward and upward from the tail end(s) of the middle section (cs). The volute casing 22 is located behind the volute tongue 21 and is of a curved structure with a concave side facing forwards as a whole. The upper surface (ed section) of the separation strip 23 gradually inclines downward from back to front to form a gradually expanding outlet of the air duct 20 together with the air outlet section (sa). The upper surface (ed section) of air-out section (sa) and parting bead 23 can be further made to be the arc of indent, and each section all with fillet transition to the direction of messenger's air current changes more gently, reduces the flow loss.

The embodiment of the utility model at least has the following air supply modes for users to select, and specifically comprises the following steps:

a forward air supply mode: as shown in fig. 3, the flow divider 30 is moved forward to open the first air blowing port 11, and the air deflector 60 closes the second air blowing port 12 or opens the second air blowing port 12 at a small angle to prevent condensation, so that air is divided forward from the first air blowing port 11. When the air conditioner operates in the cooling mode, air can be supplied according to the air supply mode.

Downward air supply mode: as shown in fig. 4, the control flow divider 30 closes the first air blowing port 11 and opens the second air blowing port 12 by the air deflector 60. The air is blown downward by the second blowing port 12 under the guidance of the air guide plate 60. When the air conditioner operates in a heating mode, air can be supplied according to a lower air supply mode, so that the heating speed is accelerated. In this mode, the air deflector 60 can be in a vertically extending state, and the end thereof is adjacent to the volute tongue 21 of the air duct 20, so as to guide the air flow to flow in a downward bending manner to the second air outlet 12. After the airflow enters the air duct 20, the cross section is gradually increased to realize diffusion, the airflow is turned to be vertically downward under the action of the air deflector 60, and then the airflow passes through a tapered channel defined by the air deflector 60 and the volute 22 of the air duct 20 to realize acceleration before flowing out. Finally, the air quantity of the heating air supply is large, the air speed is high, the wind direction is vertical, the hot air can directly reach the ground, and the carpet type air supply effect is good.

The maximum air supply mode is as follows: as shown in fig. 5, both the first outlet 11 and the second outlet 12 are opened to simultaneously discharge air so as to maximize the air volume.

Fig. 6 is a schematic view of the drive mechanism of the diverter. Fig. 2 to 5 are views illustrating the wind path direction better and omitting the driving mechanism, and fig. 6 is a view illustrating the driving mechanism better and omitting the air deflector 60.

In some embodiments, as shown in fig. 6, the driving mechanism for driving the splitter 30 to translate back and forth is a rack and pinion mechanism, which is mounted to the lateral side of the enclosure 10 so as not to affect the airflow. The driving mechanism includes a rack 71 extending in the forward-backward direction and fixed to the splitter 30, a gear 72 engaged with the rack 71, and a motor 73 for driving the gear 72 to rotate to move the rack 71 forward and backward. The motor 73 may be fixed to the cabinet 10, and the rack 71 may be slidably installed to the cabinet 10 in the front and rear directions. The motor 73 is controllably reversible to enable the splitter 30 to translate back and forth in a reciprocating manner. The motor 73 may be a stepper motor.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the utility model may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the utility model. Accordingly, the scope of the utility model should be understood and interpreted to cover all such other variations or modifications.
