Description

Technical Field

[0001] The present application relates to the technical field of air conditioning equipment, and in particular to an air-conditioning indoor unit, an air conditioner, and a control method. Background Art

[0002] When the air conditioner indoor unit is operating in cooling or heating mode, the air outlet angle is usually adjusted by using an air guide plate to change the air outlet direction. During cooling, the cold air sinks, and the air outlet should be adjusted to blow upwards; while during heating, the hot air rises, and the air outlet should be adjusted to blow downwards.

[0003] However, due to volume limitations, existing air-conditioning indoor units can only be equipped with air guide plates that match the air outlet area at the air outlet. The air guide range of the air guide plates is small, which leads to uneven indoor temperature distribution and poor user experience. Summary of the Invention

[0019] In a possible implementation of the present application, the air guide plate includes a plurality of sub-plates spaced apart on one side of the main plate, wherein the angles between the sub-plates and the main plate increase successively in a direction away from the main plate.

[0020] In a possible implementation of the present application, an adsorption component is further provided on a side of the air curtain away from the body. When the air curtain is in an extended state, the adsorption component is used to adsorb on a wall and stretch and unfold the air curtain.

[0044] Please refer to Figures 1 to 5 The embodiment of the present application provides an air conditioner indoor unit 100, comprising:

[0045] The body 200 has an air outlet 220 , and an air guide plate 500 is provided at the air outlet 220 ;

[0046] An air curtain 400 with a plurality of micro-holes 410 is provided on the body 200, and an air guide 420 is formed between the air curtain 400 and the body 200;

[0047] The air curtain 400 has an extended state and a retracted state. When the air curtain 400 is in the extended state, the air curtain 400 is horizontally extended and opened in a direction away from the body 200.

[0048] When the air curtain 400 is in the extended state, the air guide plate 500 guides the air flow blown out of the air outlet to flow obliquely upward through the air guide port 420 to the top of the air curtain 400 , and then flows through the micropores 410 to the bottom of the air curtain 400 .

[0049] It should be noted that the air-conditioning indoor unit 100 provided in the embodiment of the present application is preferably a wall-mounted air-conditioning unit, and an air inlet 210 and an air outlet 220 are formed on the body 200; of course, technicians can also set the air-conditioning indoor unit to a cabinet air-conditioning unit or a central air-conditioning unit according to actual needs.

[0050] It should also be noted that the air conditioner (not shown in the figure) usually has two operating modes: cooling and heating. When the air conditioner is turned on in cooling mode, the temperature of the air flow blown out from the air outlet 220 of the air conditioner indoor unit 100 is usually lower than the indoor ambient temperature. Therefore, the air flow blown out from the air outlet 220 at this time is called cold air. Since the distance between the molecules of cold air is smaller and the density is larger than that of the indoor air, the cold air has a tendency to sink after being blown out; when the air conditioner is turned on in heating mode, the temperature of the air flow blown out from the air outlet 220 of the air conditioner indoor unit 100 is usually higher than the indoor ambient temperature. Therefore, the air flow blown out from the air outlet 220 at this time is called hot air. Since the distance between the molecules of hot air is larger and the density is smaller than that of the indoor air, the cold air has a tendency to rise after being blown out.

[0051] In addition, the existing air-conditioning indoor unit 100 is usually provided with a soft wind plate with a porous structure at the air outlet 220 to evenly disperse the large air flow into multiple small air flows, thereby achieving the effect of uniform and soft wind. However, due to the volume limitation of the body 200, the area of ​​the soft wind plate at the air outlet 220 is relatively small and the soft wind plate is usually provided close to the air outlet 220, which is usually located at the edge of the room and away from the actual location of the user. As a result, the multiple small air flows passing through the soft wind plate may affect each other again after being blown out for a certain distance and form mixed flow or vortex, etc., thereby resulting in uneven temperature field distribution; and the air flow flowing out of the soft wind plate needs to be swept back and forth at multiple angles under the guidance of the wind guide mechanism in order to cover the entire indoor space, which further aggravates the phenomenon of uneven indoor temperature field distribution.

[0052] By disposing an air curtain 400 above the air outlet 220, the air curtain 400 has an extended state (horizontally extended) and a retracted state (retracted). When the air conditioner indoor unit 100 is in cooling mode, the air curtain 400 is extended horizontally, and the air guide plate 500 directs the airflow diagonally upward above the air curtain 400. This allows the cool air to diffuse evenly above the air curtain 400 before flowing evenly and slowly downward through the multiple micropores 410 in the air curtain 400. This creates a more uniform indoor temperature distribution and forms multiple streams of cool air flowing from top to bottom, providing greater user comfort. When the air conditioner indoor unit 100 is in heating mode, the air guide plate 500 directs the airflow diagonally downward below the air curtain 400. The extended air curtain 400 prevents hot air from rising further, thereby increasing the indoor temperature rise rate. When the air curtain 400 is not needed, it can be retracted to reduce space usage.

[0053] In particular, when air curtain 400 is horizontally unfolded, because its surface area is much larger than that of a conventional porous soft air plate, the cold air above air curtain 400 can continue to diffuse evenly in all directions along the surface of air curtain 400, thereby increasing the coverage of the cold air. Furthermore, the embodiment of the present application can also be configured with air curtains 400 of different sizes based on actual needs, providing greater versatility.

[0054] Specifically, the micropores 410 are in the shape of circular holes.

[0055] Furthermore, in other embodiments, the shape of the microhole 410 can also be a triangular hole, a rectangular hole, or a special-shaped hole, etc., which is not excessively limited here.

[0056] Specifically, the plurality of micro-holes 410 on the air curtain 400 are arranged in an array, for example, a rectangular array or a circular array.

[0057] Specifically, the air curtain 400 can be made of flexible transparent plastic to facilitate the storage of the driving mechanism and better visual light effects.

[0058] Specifically, the air guide plate 500 is a rectangular plate-shaped member, which can be well adapted to the wall-mounted air-conditioning indoor unit 100 ; and the air guide plate 500 is rotatably installed at the air outlet 220 .

[0059] In some embodiments, the air conditioning indoor unit 100 includes a telescopic mechanism 310 and a storage mechanism 320;

[0060] The telescopic mechanism 310 is connected to the body 200 and the storage mechanism 320 respectively. One end of the air curtain 400 is fixed on the telescopic mechanism 310, and the other end is connected to the storage mechanism 320. The telescopic mechanism 310 is used to drive the storage mechanism 320 to reciprocate in the direction of approaching or moving away from the body 200, and the storage mechanism 320 is used to drive the air curtain 400 to extend and open or retract and store in an orderly manner.

[0061] It is understandable that since the wind curtain 400 is usually made of flexible material, the wind curtain 400 can be unfolded by pulling the two ends of the wind curtain 400. When it needs to be retracted and stored, the wind curtain 400 that has lost tension may be randomly squeezed and twisted during the retraction and storage process, which may cause wrinkles or even damage to the surface of the wind curtain 400.

[0062] By providing the storage mechanism 320, when the telescopic mechanism 310 drives the storage mechanism 320 to move in a direction away from the body 200, it can pull one end of the air curtain 400 to unfold the air curtain 400, and when the telescopic mechanism 310 drives the storage mechanism 320 to move in a direction close to the body 200, it can retract and store the air curtain 400 in a regular and orderly manner, thereby avoiding wrinkles or even damage on the surface of the air curtain 400, and extending the service life of the air curtain 400.

[0063] Optionally, the telescopic mechanism 310 can store the air curtain 400 in a curling or folding manner.

[0064] Furthermore, in other embodiments, when the telescopic mechanism 310 and the storage mechanism 320 drive the air curtain 400 to extend and open, the telescopic mechanism 310 and the storage mechanism 320 can also drive the air curtain 400 to rotate in the horizontal plane and / or vertical plane to flexibly adjust the flow direction and coverage range of the airflow flowing out through the air curtain 400, and no excessive restrictions are made here.

[0065] In some embodiments, the telescopic mechanism 310 is a telescopic rod 311 having a fixed end 312 and a telescopic end 313 , wherein the fixed end 312 is fixed to the body 200 and the telescopic end 313 has a tendency to reciprocate toward or away from the body 200 ;

[0066] The storage mechanism 320 includes a reel 321 and a drive motor (not shown). The drive motor is mounted on the telescopic end 313. The drive shaft of the drive motor is connected to the reel 321. One side of the air curtain 400 is fixed to the fixed end 312 and spaced apart from the body 200. The other side is wound around the reel 321.

[0067] When the air curtain 400 is in a retracted state, the telescopic end 313 moves toward the direction close to the fixed end 312, and the drive motor rotates forward to wind up the air curtain 400. When the air curtain 400 is in an extended state, the telescopic end 313 moves toward the direction away from the fixed end 312, and the drive motor rotates reversely to unfold the air curtain 400.

[0068] By fixing the fixed end 312 on the body 200, when the telescopic end 313 reciprocates in the direction of approaching or moving away from the body 200, since one end of the air curtain 400 is fixed on the fixed end 312 and the other end is indirectly fixed to the telescopic end 313 through the storage mechanism 320, the telescopic mechanism 310 can stretch and unfold or retract and store the air curtain 400; in addition, by arranging a drive motor at the telescopic end 313 and arranging a reel 321 on the transmission shaft of the drive motor, when the drive motor drives the reel 321 to rotate, the reel 321 can roll up the air curtain 400 to complete the orderly curling and storage of the air curtain 400, thereby reducing the possibility of wrinkles or even damage on the surface of the air curtain 400, and extending the service life of the air curtain 400.

[0069] Specifically, the telescopic mechanism 310 can also be composed of multiple sections of round tubes of different diameters that are arranged in sequence. The overall length of the telescopic mechanism 310 can be adjusted by adjusting the depth of the smaller diameter tube inserted into the larger diameter tube, thereby unfolding or retracting the wind curtain 400. The principle is similar to that of a fishing rod. In addition, the telescopic mechanism 310 can also be a screw mechanism or a cylinder, etc., which is not limited here.

[0070] Preferably, the circular tube with the largest diameter is fixed on the body 200, i.e., the fixed end 312, and one end of the air curtain 400 is fixed on the side wall of the circular tube and spaced apart from the body 200; and the circular tube with the smallest diameter is regarded as a free end, which can be slid and stretched to the farthest distance from the circular tube with the largest diameter.

[0071] Preferably, the air-conditioning indoor unit 100 includes two telescopic rods 311, which are respectively clamped on both sides of the air curtain 400, and the telescopic ends 313 of the two telescopic rods 311 are respectively connected to the drive motor and the other end of the reel 321 away from the drive motor to enhance the structural strength of the air-conditioning indoor unit 100.

[0072] Furthermore, in some other embodiments, the storage mechanism 320 can also be a coil spring (not shown in the figure). Since the coil spring has a tendency to curl and return to its original position, the coil spring can be aligned along the extension direction of the air curtain 400. When the air curtain 400 needs to be deployed, the retractable mechanism 310 pulls the coil spring to expand and secure it. When the air curtain 400 needs to be retracted, the coil spring can automatically curl and retract the air curtain 400.

[0073] Furthermore, in some other embodiments, the storage mechanism 320 may also include a plurality of “Z”-shaped folding plates connected in sequence (not shown in the figure).

[0074] It is understandable that when the wind curtain 400 is stored in a rolled-up manner, the wind curtain 400 needs to be wound multiple times and the winding diameter gradually increases; among them, the winding diameter of the inner circle is smaller, which may cause extrusion deformation and damage to the surface of the wind curtain 400.

[0075] By setting a "Z"-shaped folding plate and covering the wind curtain 400 on the "Z"-shaped folding plate, when the wind curtain 400 needs to be retracted, the "Z"-shaped folding plate can be folded in sequence and drive the folding and storage of the wind curtain 400. Its principle is similar to that of a folding solar panel, and it ensures that the bending radius of the wind curtain 400 is consistent each time it is folded, avoiding damage to the wind curtain 400 due to a too small bending radius.

[0076] In some embodiments, the air curtain 400 includes two pieces of curtain fabric (not shown in the figure) stacked one above the other and a staggered mechanism (not shown in the figure);

[0077] A plurality of micropores 410 are spaced apart on the surface of the curtain. The interlacing mechanism connects the two curtains respectively and is used to drive the relative movement of the two curtains so that the micropores 410 on the two curtains are aligned or staggered.

[0078] It should be noted that the porosity is the ratio of the total area of ​​the openings in the opening region to the area of ​​the opening region.

[0079] It is understandable that when the heating mode is turned on, since hot air will rise spontaneously, the hot air can easily enter the upper space of the air curtain 400 through the micropores 410 on the surface of the air curtain 400, thereby affecting the reduction of the indoor heating rate.

[0080] By setting the air curtain 400 as two pieces of curtains stacked up and down, when the cooling mode is turned on, the staggered mechanism drives the micropores 410 of the two pieces of curtains to align. At this time, the opening rate of the surface of the air curtain 400 is the largest, so that the cold air can settle through the micropores 410 with the highest efficiency; when the heating mode is turned on, the staggered mechanism drives the micropores 410 of the two pieces of curtains to stagger to reduce the opening rate of the air curtain 400, which reduces the air flow rate of hot air rising through the micropores 410, thereby increasing the indoor temperature rise rate; in particular, when the micropores 410 of the two pieces of curtains are completely staggered until their projections on the horizontal plane do not overlap, that is, when the opening rate of the air curtain 400 is zero, hot air cannot pass through the air curtain 400, which can maximize the indoor temperature rise rate.

[0081] Specifically, the interlacing mechanism can be a rotating motor (not shown in the figure), and one side of the two curtains are respectively connected to the surface of the transmission shaft of the rotating motor at intervals. When the transmission shaft of the rotating motor rotates, the two curtains have different winding lengths on the transmission shaft of the rotating motor, thereby achieving relative movement between the two curtains.

[0082] In some embodiments, in a direction away from the machine body 200 , the air curtain 400 has a plurality of air outlet areas (not shown in the figure) that are sequentially arranged and have increasing opening ratios.

[0083] It is understandable that when cold air enters the upper side of the air curtain 400 through the air guide port 420, the airflow of the cold air decreases in the direction away from the body 200, so the closer the area is to the air guide port 420, the greater the airflow of the cold air.

[0084] By setting multiple air outlet areas on the surface of the wind curtain 400, and the air outlet area closer to the air guide port 420 has a lower opening rate, that is, the cold air closer to the air guide port 420 passes through the wind curtain 400 at a slower speed; this allows more cold air to be squeezed and blown to the air outlet area with a higher opening rate by the subsequent cold air airflow, thereby making the distribution of cold air on the upper side of the wind curtain 400 more uniform, thereby promoting a more uniform distribution of the indoor temperature field.

[0085] In some embodiments, the air guide plate 500 includes a main plate 510 and a sub-plate 520 that are spaced apart. The plane where the main plate 510 is located is set at an angle to the plane where the sub-plate 520 is located. The main plate 510 and the sub-plate 520 are respectively used to guide the airflow to blow out at different angles.

[0086] It is understandable that, at the same speed, different emission angles will cause the airflow trajectory to present different parabolic trajectories.

[0087] By cooperating with the main board 510 and the sub-board 520, a large airflow blown out of the air outlet 220 can be dispersed into two small airflows blown out in different directions; and because the two plates are arranged at an angle, the flow trajectories of the two small airflows are different, resulting in different landing points of the two airflows on the air curtain 400, effectively avoiding the gathering of airflow on the air curtain 400, thereby making the distribution of cold air on the upper side of the air curtain 400 more uniform.

[0088] In some embodiments, the air guide plate 500 includes a plurality of sub-plates 520 spaced apart on one side of the main plate 510 , wherein the angles between the sub-plates 520 and the main plate 510 increase successively in a direction away from the main plate 510 .

[0089] By providing multiple sub-plates 520 with successively increasing angles relative to the main plate 510, multiple air ducts with different orientations are formed between the main plate 510 and its adjacent sub-plates 520, as well as between the sub-plates 520, with the angles between the extension directions of adjacent air ducts and the horizontal plane successively increasing. In this way, the air guide plate 500 can disperse a large airflow from the air outlet 220 into multiple small airflows with concentric ring-like flow paths. Specifically, the landing points of the multiple small airflows on the air curtain 400 are arranged in a direction away from the body 200, thereby improving the uniformity of the distribution of cold air above the air curtain 400. Furthermore, the flow paths of the multiple small airflows do not overlap, effectively avoiding the generation of mixed flows and vortices, reducing the loss of cold air above the air curtain 400 and lowering aerodynamic noise.

[0090] In some embodiments, an adsorption component is further provided on the side of the air curtain 400 away from the body 200. When the air conditioner indoor unit is in an extended state, the adsorption component is used to be adsorbed on the wall and stretch the air curtain 400.

[0091] By providing the adsorption component, when the air curtain 400 is unfolded, the adsorption component can help fix the air curtain 400, thereby improving the stability of the air curtain 400 when unfolded.

[0092] Specifically, the adsorption component can be a plurality of suction cups or hooks arranged at intervals.

[0093] The present application also provides an air conditioner, comprising the air conditioner indoor unit 100 and the air conditioner outdoor unit as described above, wherein the air conditioner outdoor unit is connected to the air conditioner outdoor unit. Since the air conditioner has the above-mentioned air conditioner outdoor unit, it has all the same beneficial effects, and the present invention will not be repeated here.

[0094] The present application also provides a control method, which includes:

[0095] Get the indoor ambient temperature and the operating mode of the air conditioner;
