The diversion piece is internally provided with a cavity, and is provided with an air inlet hole and an air outlet hole which are communicated with the cavity, so that air flow in the shell enters the cavity through the air inlet hole and is blown out through the air outlet hole.
Optionally, the air deflector is configured to be rotatable relative to the air duct so as to adjust the air outlet direction of the air outlet.
Optionally, the outlet of the air duct adjacent to the first air supply opening is in a strip shape, and the length direction of the outlet is parallel to the transverse direction of the machine shell; the flow guide piece is in a column shape extending along the transverse direction of the shell, and an air outlet gap is defined between the flow guide piece and the inner walls of the two sides of the air duct in the width direction; and the flow guide piece can rotate around an axis parallel to the length direction of the flow guide piece so as to rotationally adjust the distance between the flow guide piece and the inner walls on two sides of the air duct in the width direction and adjust the air outlet quantity of the air outlet gap.
Optionally, the number of the air outlet holes is multiple; and at least part of the air outlet holes are long strips with the length direction parallel to the length direction of the flow guide piece and are arranged at intervals along the circumferential direction of the flow guide piece.
Optionally, the flow guide is generally elliptical cylindrical.
Optionally, the number of the first air supply outlets is multiple, and the multiple first air supply outlets are arranged at the front part of the casing and are arranged at intervals along the transverse direction of the casing.
Optionally, the casing is configured to make the upward-raising angle of the airflow at the bottom section of the air-out gap greater than the downward-lowering angle of the airflow at the top section thereof, so that the airflow at the bottom section of the air-out gap drives the airflow at the remaining sections to flow upward and forward together.

Optionally, the bottom of the casing is provided with a second air supply outlet which is open downwards and communicated with the air duct.
In the wall-mounted air conditioner indoor unit, the inner wall of the air duct close to the first air supply opening is gradually reduced, so that the overflowing section of the air duct is gradually reduced along the airflow direction. The air outlet gap is limited between the flow guide piece in the air duct and the inner wall of the air duct. When the airflow blows to the first air supply outlet, the airflow is guided by the flow guide piece to flow to the inner wall of the air duct and enter the air outlet gap. 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 gradually-reduced inner wall of the air duct 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. In addition, because the diversion part is of a hollow structure, the airflow in the shell can also penetrate through the diversion part and converge into the polymerization air supply airflow through the air outlet of the diversion part, so that the air volume of the polymerization air supply airflow is larger.
Furthermore, the wall-mounted air conditioner indoor unit can adjust the air outlet direction of the air outlet hole by rotating the flow guide piece, so that the direction of the aggregated air supply flow is adjusted, and the air can be supplied to a local area with larger air volume demand. In addition, the size of the air outlet gap can be adjusted in the rotation process of the flow guide piece so as to change the wind power of the first air supply outlet. Specifically, the wind power can be improved by enlarging the air outlet gap, and the refrigeration/heating can be carried out quickly; wind power is reduced by adjusting the air outlet gap to be small, natural wind is simulated, and the air flow comfort degree is higher. The flow guide member may be in the shape of an elliptical cylinder. The oval cylindrical flow guide piece rotates around an axis parallel to the length direction of the oval cylindrical flow guide piece, so that the distance between the oval cylindrical flow guide piece and the inner walls of two sides of the air channel in the width direction can be changed, the air outlet gap can be adjusted, the structure is very simple, and a complex driving mechanism is not required to be arranged.
In the wall-mounted air conditioner indoor unit, the flow guide piece not only defines the air outlet gap with the inner wall of the air channel to improve the air speed, but also can guide the air flow to the air outlet gap or force the air flow to flow towards the air outlet gap so as to force the air flow to be subjected to polymerization and guide of the tapered inner wall of the air channel, thereby forming the final polymerization air supply effect. The invention realizes a good polymerization air supply effect only by improving the air duct and additionally arranging the flow guide piece, has very simple structure and lower cost, is easy to realize mass production and popularization, and has very ingenious conception.
Furthermore, the wall-mounted air conditioner indoor unit provided by the invention designs the shape of the air duct, so that the rising angle of the airflow at the bottom section of the air outlet gap is larger than the declining angle of the airflow at the top section, the rising angle of the rising part of the airflow is larger than the declining angle of the sinking part, and the airflow mixed by a plurality of airflows is integrally raised and flows. In the refrigeration mode, the rising and flowing cold air can fully avoid the human body and scatter downwards after reaching the highest point, so that the shower type refrigeration experience is realized. Moreover, the air flow is blown upwards to be beneficial to improving the air supply distance.
Furthermore, the wall-mounted air conditioner indoor unit of the invention is provided with a second air supply outlet facing downwards at the bottom of the casing, so as to supply air to the lower part of the wall-mounted air conditioner 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.
Furthermore, the wall-mounted air conditioner indoor unit of the invention enables the top of the shell to be provided with the first air inlet and the front part to be provided with the second air inlet, so that the air inlet volume is increased, the heat exchange efficiency of the front section of the heat exchanger is improved, and the overall energy efficiency of the air conditioner is improved. In addition, the movable panel is utilized to simultaneously open or close the second air inlet and the first air supply outlet, and the conception is very ingenious.

Detailed Description
A wall-mounted type air conditioning indoor unit according to an embodiment of the present invention will be described with reference to fig. 1 to 9. Where the orientations or positional relationships indicated by the terms "front," "back," "upper," "lower," "top," "bottom," "inner," "outer," "lateral," and the like are based on the orientations or positional relationships shown in the drawings, the description is for convenience only and to simplify the description, and no indication or suggestion is made that the device or element so indicated must have a particular orientation, be constructed and operated in a particular orientation, and is therefore not to be construed as limiting the invention. The direction of the airflow is indicated by arrows.
The embodiment of the invention provides a wall-mounted air conditioner indoor unit, which is an indoor part of a split wall-mounted air conditioner and is used for adjusting indoor air, such as refrigeration/heating, dehumidification, fresh air introduction and the like.

Fig. 4 illustrates only the air blowing principle of the wall-mounted air conditioner indoor unit, and the partial structure is not completely consistent with fig. 1 to 3.
As shown in fig. 1 to 6, 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.
The casing 10 defines a first blowing port 11 and an air duct 15 communicating with the first blowing port 11. 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 channel. 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 number of the first blowing ports 11 may be one or more. The inner wall of the air duct 15 adjacent to the first air supply outlet 11 is tapered, and the flow cross section of the inner wall is gradually reduced along the airflow direction, as shown in fig. 4. 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 diversion member 30 is disposed in the air duct 15, and defines an air outlet gap 155 with an inner wall of the air duct 15. For example, as shown in fig. 4, the air guiding element 30 is spaced from both the upper wall 151 and the lower wall 152 of the air duct 15 adjacent to the first air supply outlet 11, so as to form an air outlet gap 155 with the upper wall 151 and the lower wall 152. The guide member 30 guides the air flow blown toward the first air blowing opening 11 to the inner wall of the air duct 15, so that the air flow gradually converges toward the center of the air flow and flows out of the first air blowing opening 11 under the guidance of the tapered portion (i.e., the upper wall 151 and the lower wall 152) of the inner wall of the air duct 15.
Due to the addition of the flow guide 30, the flow cross section of the outlet air gap 155 is necessarily smaller than the original flow cross section of the 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 guidance of the tapered inner wall of the air duct 15 to form a convergence effect, and becomes converged air supply flow, so that the wind power is very strong, the air supply distance is farther, the requirements of the 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 feeling is more comfortable. The air guiding element 30 not only defines an air outlet gap 155 with the inner wall of the air duct 15 to play a role of increasing the wind speed, but also just forces the airflow to flow towards the air outlet gap 155 so as to force the airflow to be subjected to the polymerization and guidance of the tapered inner wall of the air duct 15, thereby forming the final polymerization air supply effect. The embodiment of the invention 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.
As shown in fig. 4 to 6, a cavity 301 is formed inside the guiding element 30, and the guiding element 30 is provided with an air inlet 321 and an air outlet 311 communicating with the cavity 301, so that the air inside the casing 10 enters the cavity 301 through the air inlet 321 and is blown out through the air outlet 311. That is, the air flow inside the housing 10 can flow outwardly through the diversion member 30 to join the aforementioned converging blowing air flow. This allows for a greater volume of the polymerization feed gas stream. The number of the air inlet holes 321 and the air outlet holes 311 can be one or more.
Fig. 7 is a schematic view of the wall-mounted air conditioning indoor unit shown in fig. 4 after adjusting an outlet air gap.
In some embodiments, the deflector 30 is configured to rotate relative to the duct 15 to adjust the direction of the air exiting from the air outlet holes 311, and thus adjust the direction of the converging supply airflow to supply air specifically to a local area with a greater air demand.
Specifically, as shown in fig. 4 to 6, the outlet of the air duct 15 adjacent to the first supply port 11 may be shaped as a long strip whose length direction is parallel to the lateral direction of the casing 10. Correspondingly, the air guiding member 30 is a column extending along the transverse direction of the casing 10, and defines an air outlet gap 155 with the inner walls (in the embodiment shown in fig. 4, the upper wall 151 and the lower wall 152, respectively) at both sides of the width direction of the air duct 15. The air guide member 30 can rotate around an axis parallel to its length direction to rotatably adjust the distance between the air guide member and the inner walls (the upper wall 151 and the lower wall 152) at both sides of the air duct in the width direction, so as to adjust the size of the air outlet gap 155. Therefore, after the diversion member 30 rotates a certain angle, not only the orientation of the air outlet 311 changes, but also the size of the air outlet gap 155 changes, so that the flow area of the air outlet gap 155 changes, and the wind power of the first air supply opening 11 is further changed.
Therefore, the wall-mounted air conditioning indoor unit of the embodiment can change the air outlet mode by rotating the air guide member 30. For example, when the difference between the indoor temperature and the set temperature is small (for example, within 1 ℃), the air outlet gap 155 may be adjusted to be small, and the air is blown in a micro-polymerization blowing manner, so that the cold/hot air body feels more comfortable, as shown in fig. 4. And the low air volume operation can also reduce the cooling/heating capacity, so that the indoor temperature is kept constant. When the difference between the indoor temperature and the set temperature reaches a certain degree (for example, more than 2 ℃), the air outlet gap can be enlarged, air is supplied in a strong polymerization air supply mode, the wind power is improved, and the cooling/heating is performed quickly, as shown in fig. 7.
As shown in fig. 4 to 6, it is preferable that the flow guide member 30 has an elliptical cylindrical shape as a whole. When the major axis of the ellipse of the air guide member 30 extends substantially along the width direction of the air duct, the air outlet gap 155 is the smallest. When the major axis of the ellipse of the air guide member 30 is substantially parallel to the airflow direction, the air outlet gap 155 is the largest. The axis of rotation of the elliptical-cylindrical flow guide member 30 may further coincide with the elliptical central axis thereof. The ratio of the major axis to the minor axis of the ellipse is preferably greater than 2. The embodiment sets up water conservancy diversion spare 30 to oval cylindric, can change its and the distance of 15 width direction both sides inner walls in wind channel through the dead axle rotation, realizes the regulation to air-out clearance 155 size, and the structure is very simple, also need not to set up complicated actuating mechanism.
Of course, other shapes for the flow guide member are possible. For example, the flow guide member is made in a non-cylindrical columnar shape. Alternatively, the baffle member may be cylindrical but have an axis of rotation offset from the central axis. The structure can also change the air outlet gap by rotating the flow guide piece through the fixed shaft.
As shown in fig. 5 and 6, the number of the air outlet holes 311 may be multiple, and at least a portion of the air outlet holes 311 are long strips with the length direction parallel to the length direction of the flow guiding member 30, and are arranged at intervals along the circumferential direction of the flow guiding member 30. The number of the air inlet holes 321 may be one.
As shown in fig. 5 and 6, the number of the first air blowing openings 11 may be multiple, and the multiple first air blowing openings 11 are opened at the front of the casing 10, so that the air flow converges at the first air blowing openings 11 and then flows forward at a high speed, the air blowing distance is further increased, and the air blowing range is wider, as shown in fig. 1. The plurality of first blowing ports 11 are arranged in the lateral direction of the casing 10, and different portions of the columnar air guide member 30 in the longitudinal direction correspond to the respective first blowing ports 11. Compare in the scheme that only sets up a rectangular form supply-air outlet, this embodiment sets up a plurality of first supply-air outlet 11 side by side for every first supply-air outlet 11's air-out area is littleer relatively, does benefit to more and improves wind speed and wind pressure, thereby does benefit to and promotes polymerization air supply effect, makes the air current polymerization degree better, and the air supply distance is farther.
Of course, in some alternative embodiments, the number of the first air supply outlet may also be one, and the first air supply outlet is an elongated strip (not shown) whose length direction is parallel to the transverse direction of the casing 10, so that the columnar flow guiding element 30 corresponds to the elongated first air supply outlet, and the detailed structure is not described again.
As shown in fig. 4, 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 force indoor air to enter the casing 10, so that the indoor air and the heat exchanger 40 complete heat exchange to form heat exchange air flow, and then force the heat exchange air flow to flow through the air duct 15 to each air supply outlet. In some embodiments, as shown in fig. 4, the casing 10 is configured to make the rising angle of the airflow at the bottom section of the air outlet gap 155 greater than the declining angle of the airflow at the top section thereof, that is, make the rising angle of the lower wall 152 of the air duct 15 greater than the declining angle of the upper wall 151, so that the airflow at the bottom section of the air outlet gap 155 drives the airflow at the remaining sections to flow upward and forward together, and fig. 4 illustrates the airflow direction with arrows, please refer to.
The upward-blowing angle refers to an included angle between the airflow direction at the bottom section of the air-out gap 155 and the horizontal plane, and the downward-tilting angle refers to an included angle between the airflow direction at the top section of the air-out gap 155 and the horizontal plane (if the airflow is blown out horizontally, the downward-tilting angle is 0 °). Because the rising angle of the air flow rising part is larger than the declining angle of the sinking part, the air flow mixed by a plurality of air flows integrally rises and flows. In the refrigeration mode, the rising and flowing cold air can fully avoid the human body and scatter downwards after reaching the highest point, so that the shower type refrigeration experience is realized. Moreover, the air flow is blown upwards to be beneficial to improving the air supply distance.
Fig. 8 is a schematic view of the wall-mounted indoor air conditioner of fig. 4 in a down-blowing mode; fig. 9 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 4 in a maximum blowing mode.
In some embodiments, the wall-mounted air conditioning indoor unit may further include a movable panel 20. The movable panel 20 is movably installed at the front side of the casing 10 to open or close the first blowing port 11. In this way, when the wall-mounted air conditioning indoor unit is in the off state, the movable panel 20 can close the first air supply outlet 11, so as to prevent the first air supply outlet 11 from being exposed to the outside and affecting the front appearance of the wall-mounted air conditioning indoor unit. This embodiment does not limit the movement of the movable panel 20 to open and close the first blowing port 11. The movable panel may be opened and closed by rotation, may be opened and closed by translation, or may be opened and closed by a combination of rotation and translation.
Further, as shown in fig. 4 to 9, a first air inlet 13 may be formed at the top of the casing 10, a second air inlet 14 may be formed at the front of the casing, and the second air inlet 14 is located above the first air outlet 11. The movable panel 20 has a closed position closing the second air intake vent 14 and the first air blowing port 11, as shown in fig. 3 and 8. The movable panel 20 also has an open position moved upward from the closed position and inclined forward at the upper end to open the first air blowing opening 11 and the second air intake opening 14, as shown in fig. 1, 2 and 4.
The inventor finds that the distance between the front section of the heat exchanger 40 of the wall-mounted air conditioner indoor unit and the front panel is too close, the gap is narrow, and the front section of the heat exchanger 40 does not normally face the air inlet at the top of the casing 10, so that the heat exchange of the front section of the heat exchanger 40 is adverse, and the improvement of the overall heat exchange efficiency of the heat exchanger 40 is affected. According to the invention, the second air inlet 14 is formed in the front part of the shell 10, so that the air inlet amount is increased, the heat exchange efficiency of the front section of the heat exchanger 40 is improved, and the overall energy efficiency of the air conditioner is improved. In addition, the present invention utilizes the movable panel 20 to open or close the second air inlet 14 and the first air outlet 11 at the same time, and the concept is very ingenious. The selection of the specific mechanism for driving the movable panel 20 to achieve the above-mentioned movement is various, and for example, the driving mechanism may include an up-down translation driving mechanism and a forward-backward push-pull driving mechanism. Or may include a translation mechanism and a rotation mechanism. These driving mechanisms are all common mechanisms in the air conditioning field, and are not described in detail herein.
In some embodiments, as shown in fig. 4 to 9, the bottom of the casing 10 may be provided with a second air supply outlet 12 which is open downwards and is communicated with the air duct 15. The air can be supplied to the lower part of the wall-mounted air conditioner indoor unit through the second air supply outlet 12. 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 wall-mounted air conditioning indoor unit further includes a wind deflector 60, and the wind deflector 60 is rotatably installed at the cabinet 10 to open or close the second blowing port 12 and guide 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.
Therefore, the wall-mounted air conditioner indoor unit provided by the embodiment of the invention can run in the following modes.
