and the controller is configured to adjust the position of the flow guide corresponding to each human sensor according to the distance value detected by each human sensor.
Optionally, an outlet of the air duct, which is close to the first air supply opening, is in a shape of a long strip with the length direction parallel to the transverse direction of the machine shell; the plurality of first air supply outlets are arranged along the transverse direction of the shell; and the water conservancy diversion spare is for the shaft-like that extends along the transverse direction of casing to all injecing the air-out clearance with the upside in wind channel and the inner wall of downside.

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. An air outlet gap is defined between the flow guide piece in the air duct and the inner wall of the air duct. When the air flow blows to the first air supply outlet, the air flow 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, the wall-mounted air conditioner indoor unit can adjust the size of an air outlet gap by moving the flow guide piece back and forth, so that the wind power of the first air supply opening is adjusted. Specifically, the air outlet gap can be enlarged by moving the flow guide piece backwards so as to improve the wind power and accelerate the refrigeration/heating speed and the air outlet distance; the air outlet gap is adjusted to be small by moving the flow guide piece forwards, so that the wind power is reduced, natural wind is simulated, and the air flow comfort degree is higher.
Furthermore, in the wall-mounted air conditioner indoor unit, because the plurality of first air supply openings are arranged, and the positions of the flow guide pieces matched with the first air supply openings are adjustable, the wind power of each first air supply opening can be independently adjusted. According to the invention, the human body sensor is arranged at each first air supply opening, so that the distance between the human body right in front of the human body sensor and the human body can be detected. When the human body is detected to be positioned at a close distance in front of the human body by the human body sensing sensor, the controller controls the corresponding flow guide piece to move forwards so as to reduce the wind power of the polymerization airflow and avoid discomfort caused by that the powerful airflow blows to the human body.
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 of 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 rises and flows integrally. When in a refrigeration mode, the rising and flowing cold air can fully avoid the human body and scatter downwards after reaching the highest point, so that a 'shower type' refrigeration experience is realized. Moreover, the air flow is blown upwards to be beneficial to improving the air supply distance.
Furthermore, the bottom of the casing of the wall-mounted air conditioner indoor unit is provided with a second air supply outlet facing downwards so as to supply air to the lower part of the wall-mounted air conditioner indoor unit. 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 casing 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 integral 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, so that the concept is ingenious.

Where the terms "front", "back", "upper", "lower", "top", "bottom", "inner", "outer", "lateral", etc. indicate orientations or positional relationships based on those shown in the drawings, this is for convenience in describing the invention and to simplify the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be taken to be limiting of 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 5, a wall-mounted type air conditioning indoor unit according to an embodiment of the present invention may generally include a cabinet 10 and a plurality of guide members 30.
The cabinet 10 has a plurality of first blowing ports 11 defined in a front portion thereof, and an air duct 15 communicating with the plurality of first blowing ports 11 defined therein. 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 a room to condition 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 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 duct 15 becomes gradually smaller in the direction of the air flow in the vicinity of the first blowing port 11.
Each of the guide members 30 corresponds to one of the first delivery ports 11. Each of the deflectors 30 is disposed within the air duct 15 and defines an air outlet gap 155 with an inner wall of the air duct 15 (in the embodiment shown in fig. 4, the upper wall 151 and the lower wall 152, respectively). The flow guiding member 30 is used for guiding the air flow blowing to the corresponding first air blowing opening 11 to the inner wall of the air duct 15, so that the air flow gradually converges to the air flow center and flows out of the corresponding first air blowing opening 11 under the guiding of the tapered part (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 air guide 30, the flow cross section of the air outlet 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 airflow is gradually converged towards the center of the airflow in the outward flowing process under the guidance of the tapered inner wall of the air duct 15 to form a convergence effect, so that the wind power is very strong, the air supply distance is longer, the requirements of a wall-mounted air conditioner indoor unit on long-distance 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. 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, 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, and 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.
As shown in fig. 4 and 5, in the embodiment of the present invention, each of the air deflectors 30 is configured to be movable in the front-rear direction so as to approach or separate from the first air outlet 11, so that the size of the air outlet gap 15 is adjustable. The wall-mounted air conditioner indoor unit can change the flow area of the air outlet gap 155 by adjusting the size of the air outlet gap 155, and further change the wind power of the first air supply outlet 11. Specifically, the air outlet gap 15 can be enlarged by moving the air guide member 30 backward to increase the wind power, accelerate the cooling/heating speed and extend the air supply distance, as shown in fig. 5; the air outlet gap 15 can be adjusted to be small by moving the diversion element 30 forward to reduce the wind power, simulate natural wind and enable the air flow comfort level to be higher, as shown in fig. 4.
Fig. 6 is a schematic block diagram of a wall-mounted air conditioning indoor unit according to an embodiment of the present invention.
In some embodiments, as shown in fig. 1 and 6, a wall-mounted indoor unit of an air conditioner may include a plurality of motion detection sensors 91 and a controller 90. Each human sensor 91 is attached to one of the first air blowing ports 11, and is configured to detect a distance between a human body located directly in front of the human sensor 91 and the human sensor 91. The controller 90 is configured to adjust the position of the airflow guide 30 corresponding to each human detection sensor 91 according to the distance value detected by the human detection sensor 91. For example, when the distance is short, the corresponding diversion element 30 can be controlled to move forward to reduce the wind force of the converging air flow and avoid discomfort caused by the strong air flow blowing to the human body. An alternative control is as follows:
let the human body in front of the human body be detected by the human sensor and the distance between the human body and the human sensor be H.
If H is more than or equal to 2m and less than or equal to 2.5m, the distance H between the diversion member 30 and the cross section of the first air supply outlet 11 is controlled as follows: h is h0(h0May be 15 mm).
If H is more than 2.5m, the controller 90 controls the diversion element 30 to move so that H is 2H0The air outlet gap 15 is larger, the wind resistance is reduced, and the air quantity are improved.
If H is less than 2m, the controller 90 controls the diversion member 30 to move so that H is equal to 0.5H0The air outlet gap 15 is smaller, the air quantity is improved, and the air speed and the air quantity are reduced.
When two or more persons are simultaneously detected in the detection area by one human detection sensor 91, the value of H is determined according to the minimum distance.
The wall-mounted type air conditioning indoor unit further includes a plurality of driving mechanisms, each of which is used to drive one of the guide members 30 to move forward and backward. Fig. 7 is a schematic view of the matching structure of the guide member and the driving mechanism.
In some embodiments, as shown in fig. 7, each of the driving mechanisms includes a rack 71 extending in the front-rear direction and fixed to the air guide 30, a gear 72 engaged with the rack 71, and a motor 73 for driving the rotation of the gear 72 to cause the rack 71 to translate back and forth. 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 allow the baffle 30 to reciprocally translate in a fore-and-aft direction. The motor 73 may be a stepper motor.
As shown in fig. 4, the outlet of the duct 15 adjacent to the first air blowing opening 11 may be formed in a long strip shape with the length direction parallel to the transverse direction of the casing 10, and the plurality of first air blowing openings 11 are arranged along the transverse direction of the casing 10. Each of the air guides 30 has a cylindrical shape extending in 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) of the upper side and the lower side of the air duct 15.
As shown in fig. 5, the contoured surface of the baffle 30 may be made to include a curved front surface 31 that is convex toward the front and a "V" shaped rear surface 32 that is convex toward the rear. The rear surface of the flow guide member 30 is V-shaped, which 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 curved front surface 31 of the deflector 30 protruding forward can guide the airflow near the deflector to flow close to the surface so as to converge toward the center of the deflector, so as to perform a converging action on the airflow together with the tapered inner wall of the air duct 15, thereby improving the converging effect of the airflow. The curved front surface 31 may be a circular arc surface or a similar circular arc surface formed by connecting multiple circular arc surfaces.
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 airflows at the remaining sections to flow upward together, specifically, the wind direction is indicated by the arrow in fig. 4.
The rising angle refers to an included angle between the airflow direction of the bottom section of the air outlet gap 155 and the horizontal plane, and the declining angle refers to an included angle between the airflow direction of the top section of the air outlet gap 155 and the horizontal plane (if the airflow is blown out horizontally, the declining 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. And 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 plurality of first blowing ports 11. In this way, when the wall-mounted air conditioning indoor unit is in the off state, the movable panel 20 can close the plurality of first air supply outlets 11, so as to prevent the first air supply outlets 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 plurality of first air outlets 11. The movable panel 20 has a closed position closing the second air intake vent 14 and the plurality of first air blowing ports 11, as shown in fig. 3 and 8. The movable panel 20 also has an open position moved upward from the closed position and tilted forward at the upper end to open the first and second air blowing openings 11 and 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 opens or closes the second air inlet 14 and the plurality of first air supply outlets 11 simultaneously by using the movable panel 20, 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. 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.
Polymerization air supply mode: as shown in fig. 4 and 5, the air deflector 60 closes the second air supply outlet 12, the movable panel 20 opens the second air inlet 14 and the first air supply outlet 11, and the air is gathered and blown up by the first air supply outlet 11, so that the air flow avoids the human body and then scatters downwards after reaching the highest point, and a 'shower type' refrigeration experience is realized. When the air conditioner runs in a refrigeration mode, air can be supplied according to a polymerization air supply mode.
A lower air supply mode: as shown in fig. 8, the air guide plate 60 opens the second air blowing port 12, closes the movable panel 20, and blows air downward through the second air blowing port 12. When the air conditioner runs in a heating mode, air can be supplied according to a lower air supply mode, so that the heating speed can be increased.
The maximum air supply mode is as follows: as shown in fig. 9, the second air blowing port 12 is opened by the air deflector 60, the second air inlet 14 and the first air blowing port 11 are opened by the movable panel 20, the air is blown upward by the first air blowing port 11, and the air is blown downward by the second air blowing port 12. When the air conditioner operates in a cooling or heating mode, the maximum air supply mode can be selected.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
