Because the overflowing cross section of the air outlet gap is smaller, the air outlet speed is higher. The high-speed airflow is gradually converged towards the center of the airflow in the outward flowing process under the guidance of the air duct reducing section to form a convergence effect, so that the wind power is stronger, the air supply distance is longer, and the requirements of the wall-mounted air conditioner indoor unit on long-distance air supply and strong air supply are met.

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. 4 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 after the guide member is swung forward by 7.5 °.

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 guide 30.

A first air supply outlet 11 is formed in the front of the casing 10 and extends in the transverse direction. The cabinet 10 is a long bar extending in a horizontal direction for hanging on an indoor wall. The lateral direction of the housing 10, i.e. its length direction, is indicated by x in the figure. An air duct 15 connected to the first blowing port 11 is formed inside the casing 10. 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 the air duct 15, and is not a pure air conditioning casing. 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. The distance between the upper wall 151 (specifically, the ba section) and the lower wall 152 (specifically, the ed section) of the air duct 15 adjacent to the first air supply outlet 11 is gradually reduced along the airflow direction, so as to form a tapered section of the air duct 15, as shown in fig. 2. In other words, the flow cross section of the air duct 15 becomes gradually smaller in the air flow direction adjacent to the first supply outlet 11.

The flow guide member 30 is a rod-shaped member parallel to the longitudinal direction (x direction) of the first air blowing opening 11, is disposed in the air duct 15, and defines

air outlet gaps

154 and 155 with (the sa section of) the upper wall 151 and (the ed section of) the lower wall 152 thereof, respectively, and is configured to guide the air flow blown toward the first air blowing opening 11 to the upper wall 151 and the lower wall 152 of the air duct 15, so that the air flow gradually flows out of the first air blowing opening 11 toward the center of the air flow while being converged under the guidance of the tapered section (defined by the ba section of the upper wall and the ed section of the lower wall) of the air duct 15.

Due to the addition of the air guide 30, the flow cross section of the

outlet air gaps

154, 155 is necessarily smaller than that of the original air duct 15, which makes the air flow velocity faster. The high-speed air flow is gradually converged towards the center direction of the air flow in the outward flowing process under the guide of the gradually-reduced section of the air duct 15 to form a convergence effect, so that the wind power is very strong, the air supply distance is farther, the requirements of a wall-mounted air conditioner indoor unit on remote air supply and strong air supply are met, the air supply range is larger, the refrigerating/heating speed of each part of the indoor space is more uniform, and the human body feels more comfortable.

In the embodiment of the present invention, the flow guiding element 30 not only defines the

air outlet gaps

154 and 155 with the upper wall 151 and the lower wall 152 of the air duct 15 to play a role of increasing the wind speed, but also just guides the airflow to the

air outlet gaps

154 and 155, or forces the airflow to flow toward the

air outlet gaps

154 and 155, so as to force the airflow to be converged and guided by the tapered section of the air duct 15, thereby forming the final converged air supply effect. The embodiment of the utility model realizes a very good polymerization air supply effect only by improving the air duct 15 and additionally arranging the flow guide member 30, has very simple structure and lower cost, is easy to realize mass production and popularization, and has very ingenious conception.

In the embodiment of the present invention, the air guiding member 30 is configured to be swingably mounted to the casing 10 around a central axis X located outside the air guiding member 30 and extending along the transverse direction (X direction) of the casing 10, so as to adjust the distance of the first air blowing opening 11 by swinging at different positions, thereby making the air volume of the first air blowing opening 11 adjustable to better match the user's needs. For example, the central axis X may be positioned above the upper wall 151 such that the baffle 30 may swing back and forth. When the diversion member 30 swings forward from the position shown in fig. 2 to the position shown in fig. 3, the distance between the diversion member and the first air supply opening 11 is closer, so that the air output of the first air supply opening 11 is blocked, and the air volume of the aggregated air supply is reduced. The guide member 30 may be further allowed to swing to a closing position for closing the first blowing port 11. In fig. 2 and 3, z and O are the major axis and center of the current state of the baffle 30, and the dashed lines z1 and O1 are the major axis and center of the baffle 30 when in the closed position.

The above-mentioned embodiment of the present invention arranges the swing central axis X of the guiding element 30 above the upper wall 151 of the air duct 15, on one hand, the position has enough space to accommodate the swing driving device (hereinafter, the motor 80), and on the other hand, the guiding element 30 has a long enough swing radius, so that the swing range is larger, and the adjustment range of the wind direction and the wind volume is larger. Of course, in some alternative embodiments, the core axis X may also be disposed below the lower wall 152 of the air chute 15.

In some embodiments, as shown in fig. 2, the wall-mounted air conditioning indoor unit includes a motor 80 and a link 81. The motor 80 is mounted above the upper wall 151 with its axis extending in the lateral direction of the casing 10 to constitute the aforementioned central axis X. The lower end of the connecting rod 81 is fixed to the diversion element 30, and the upper end is connected to the motor 80, so that the diversion element 30 is driven by the motor 80 to swing. The connecting rod 81 may be connected to one end of the air guide 30 in the length direction so as not to affect the normal air outlet of the air duct 15. The number of the connecting rods 81 may be 2 and the connecting rods are respectively connected to both ends of the air guide 30 in the length direction.

In some embodiments, as shown in fig. 2 and 3, the cross-section of the flow guide 30 (the cross-section extending in the front-rear direction cuts the flow guide 30) has an outline of an "olive" shape having upper and lower two tips, and front and rear two convex curved shapes. The convex curved surface of the guide member 30 facing backwards is very favorable for splitting the air flow into two parts and guiding the two parts upwards and downwards respectively, so that the guiding is smoother and the air flow resistance is smaller. The convex curved surface of the flow guide member 30 protruding forward can guide the airflow near the surface to flow along the surface, so as to gradually converge toward the center direction, and to perform the convergence action on the airflow together with the tapered inner wall of the air duct 15, thereby improving the convergence effect of the airflow.

In order to match the outer contour of the air guide 30, the section (as section) of the upper wall 151 of the air duct 15 defining the air outlet gap 154 is a curved section with a concave side facing downward, and may be an arc or be formed by connecting multiple arc sections, and has a front end point a, a highest point b and a rear end point s, which surround the air guide 30 above the air guide 30. The section (i.e., the section de) of the lower wall 152 of the air duct 15 for defining the air outlet gap 155 is a concave curved section extending from the rear to the front and inclined upward, and is located at the front lower part of the air deflector 30. Thus, the air outlet gap 154 and the air outlet gap 155 are both curved or further arc-shaped, so that the airflow direction is changed to be smoother, and the airflow resistance is reduced.

Because the X axis is located above the flow guide 30, and the swing radius of the lower end of the flow guide 30 is greater than the swing radius of the upper end, so that the swing distance of the lower end is longer, when the flow guide 30 swings back and forth to different angles, the distance between the flow guide 30 and the upper wall 151 and the lower wall 152 changes, the change range is different, and the change of the distance between the flow guide 30 and the lower wall 152 is larger, which causes the air volume contrast of the air outlet gap 154 of the upper wall 151 and the air outlet gap 155 of the lower wall 152 to change (specifically, the air volume of the air outlet gap 155 changes larger), so that the converged air direction changes, and the air conditioner can adjust the air direction of the aggregated air supply accordingly. For example, when the air guide 30 swings forward from the state of fig. 2 to the state of fig. 3, the wind outlet gap 154 becomes small but the wind outlet gap 155 becomes small, so that the rising airflow of the wind outlet gap 155 becomes small, and the rising angle of the combined airflow becomes small because the rising airflow is favorably converged by the impact of the falling airflow of the wind outlet gap 154. According to the embodiment of the utility model, through the special design of the shapes of the flow guide piece 30 and the upper wall 151 and the lower wall 152 of the air channel, the swing of the flow guide piece 30 not only can adjust the air quantity, but also can adjust the wind direction of the aggregated air supply, and the structure is very ingenious.

As shown in FIG. 2, the upper wall 151 of the air chute 15 also includes an inclined section (sc section) and an inlet section (ck section). The inclined segment (sc segment) is a straight line extending rearward and upward from the concave side of the upper wall 151 toward the rear end of the downwardly curved segment (as segment). The inlet section (ck section) is bent and extended forwards and upwards from the rear end of the inclined section (sc section). The inclined section (sc section) and the inlet section (ck section) of the upper wall 151 correspond to the volute tongue of a conventional cross-flow duct.

Fig. 4 is a cross-sectional view of a guide of the wall-mounted air conditioning indoor unit of fig. 1.

As shown in fig. 2-4, the cross-sectional outer profile of the baffle 30 can be made to include a front curve segment 31 and a rear curve segment 32. The top end and the bottom end of the two are transitionally connected by a round angle r. The radius of the front arc segment 31 may be made larger than the radius of the rear arc segment 32 so that the rear arc segment 32 is relatively more convex, so that the distance between the rear arc segment 32 and the upper wall 151 is smaller, and the distance between the front arc segment 31 and the upper wall 151 is relatively flatter, so that the airflow can more smoothly flow through the air outlet gap 154. Of course, in some alternative embodiments, the radius of the front arc segment 31 may also be made equal to or smaller than the radius of the rear arc segment 32. In other alternative embodiments, the front arc segment 31 and/or the rear arc segment 32 may be formed by connecting multiple arcs, and detailed descriptions of the structures are omitted.

Referring to fig. 4, the radius of the front arc segment 31 is R1, the radius of the rear arc segment 32 is R2, and the distance between the top end and the bottom end of the diversion element 30 is H, which satisfies the following conditions: R1/H is more than or equal to 0.5 and less than or equal to 0.8, R2/H is more than or equal to 0.5 and less than or equal to 0.8, and further R1/H is more than or equal to 0.3 and less than or equal to 0.6, and R2/H is more than or equal to 0.3 and less than or equal to 0.6. In this way, the width (the maximum dimension in the vertical direction) of the air guide member 30 and the curvature of the front and rear surfaces are more coordinated, so as to balance the air guiding effect and the flow resistance.

In some embodiments, as shown in fig. 2, the distance between the upper and lower edges of the first air supply opening 11 may be smaller than the distance between the top end and the bottom end of the air guiding member 30, that is, the size of the air guiding member 30 in the vertical direction is relatively larger, so that the downward inclined portion of the air outlet gap 154 formed between the air guiding member 30 and the upper wall 151 of the air duct 15 is longer, and the upward inclined portion of the air outlet gap 155 formed between the air guiding member 30 and the lower wall 152 is longer, so as to guide the air flow more strongly downward and upward obliquely, respectively, and converge in front of the air guiding member 30 with larger wind force, so that the air supply distance is longer.

Fig. 5 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 in a downward blowing mode when the guide member closes the first blowing port.

In some embodiments, the baffle 30 is configured to be swingable to a closed position closing the first supply outlet 11, as shown in fig. 5. Also, when the baffle 30 is in the closed position, its upper tip is positioned forward and above (as shown in fig. 5) or directly above the lower tip. Therefore, when the diversion member 30 swings backwards to open the first air supply outlet 11, as shown in fig. 2, the top end of the upper portion is located at the front upper side of the top end of the lower portion, so that the rear surface of the diversion member 30 faces towards the rear upper side, and the included angle between the convergent air supply direction and the air direction of the upstream air duct is smaller, so that the air flow is easier to turn to the convergent angle, the air outlet resistance is reduced, and the air volume of the convergent air supply is increased.

In some embodiments, as shown in fig. 2, the bottom wall of the casing 10 is opened with a second air supply outlet 12 which is open downwards and connected with the air duct 15. 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 duct 15 includes the aforementioned upper wall 151(ak), a lower wall 152(de) and a rear wall 153(fg) for connecting the first supply port 11 and the second supply port 12. Wherein the front end (a) of the upper wall 151 and the front end (d) of the lower wall 152 define the first blowing port 11. The rear end (e) of the lower wall 152 and the lower end (f) of the rear wall 153 define the second supply port 12, the (k-section of the) upper wall 151 and the (g-end of the) rear wall together define the inlet of the duct 15, and the cross-flow fan 50 is located at the inlet of the duct 15. The rear wall 153 is a volute of the crossflow blower which as a whole may be of a concave side forward curved configuration.

Referring to fig. 2 and 3, a wind deflector 60 is disposed at the second supply port 12. The air guide plate 60 is rotatably installed to the cabinet 10 for opening or closing the second blowing port 12 and guiding the blowing direction of the second blowing port 12. Further, an air guide mechanism such as a flap assembly may be attached to the second air supply port 12.

As shown in fig. 3, the air guide plate 60 has an upward surface serving as an air guide surface 61 and a downward surface serving as a non-air guide surface 62 in the closed state. The rear wall 153 of the air duct 15 has a concave arc-shaped section 1531(fh section), preferably in a circular arc shape, near the lower end thereof, so that when the air deflector 60 is rotated to a state where the air guiding surface 61 faces forward and upward, the air flow is guided to the non-air guiding surface 62 by the concave arc-shaped section 1531. Therefore, during the cooling operation, the air deflector 60 can be rotated to open a preset angle, so that not only the air guide surface 61 but also the non-air guide surface 62 can pass through the air deflector, and no condensation is generated on both sides of the air deflector 60. Further, when the air guide plate 60 is in the closed state, the front section thereof is bent upward, specifically, the entire front section thereof may be curved in an arc shape, or only the front section thereof may be bent. In this way, when the air deflector 60 is in the open state, the section bent from the front of the air deflector 60 guides the airflow to the outer side surface 1522 of the lower wall 152, so that the outer side surface 1522 of the lower wall 152 is not exposed to condensation. The inner side surface 1521 of the lower wall 152 serves to define the wind outlet gap 155.

Fig. 6 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 in a maximum blowing mode. The embodiment of the utility model at least has the following air supply modes for users to select, and specifically comprises the following steps:

forward polymerization blow-in mode: as shown in fig. 2, the air guiding member 30 is located behind the first air supply opening 11, the air guiding plate 60 closes the second air supply opening 12, and the air is gathered and blown upward by the first air supply opening 11, so that the air flow avoids the human body, and then is scattered downward after reaching the highest point, thereby realizing a "shower type" refrigeration experience. When the air conditioner operates in a refrigeration mode, air can be supplied according to a polymerization air supply mode.

A refrigeration condensation removal mode: as shown in fig. 3, in the cooling state, the deflector 30 opens the first air blowing opening 11, the air deflector 60 opens the second air blowing opening 12 at a small angle, and the concave arc-shaped section 1531 guides the air flow to the non-air-guiding surface 62.

Downward air supply mode: as shown in fig. 5, the deflector 30 is controlled to close the first air blowing port 11, so that the air deflector 60 opens the second air blowing port 12, and air is blown downward from the second air blowing port 12 under the guidance of the air deflector 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 may be in a vertically extending state, and the end thereof is adjacent to the upper wall 151 of the air duct 15, so as to guide the air flow to flow downward and bend to the second air outlet. After the airflow enters the air duct 15, the cross section of the airflow gradually increases to realize diffusion, the airflow is turned vertically downwards 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 rear wall 153 of the air duct 15 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. 6, the deflector 30 is positioned behind the first air blowing port 11, and the air deflector 60 opens the second air blowing port 12, so that the air is blown upward by the first air blowing port 11 and is blown forward and downward by the second air blowing port 12 under the guidance of the air deflector 60. When the air conditioner operates in a cooling or heating mode, the maximum air supply mode can be selected.

FIG. 7 is a schematic cross-sectional view of the lower wall of the duct.

As shown in fig. 3 and 7, in some embodiments, the rear end of the lower wall 152 of the air duct 15 has a wedge 1520 pointed backward for splitting the air flowing toward the rear end into two parts to flow out through the two side surfaces of the lower wall 152 respectively, so that the two side surfaces thereof are not exposed to condensation.

As shown in fig. 2, 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, and further includes a heat exchanger 40 and a blower 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 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 cause the indoor air to exchange heat with the heat exchanger 40 to form heat exchange air flow, to cause the heat exchange air flow to flow through the air duct 15 to the first air supply outlet 11 and the second air supply outlet 12, and to finally blow the air from the first air supply outlet 11 and/or the second air supply outlet 12 to the indoor space.
