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 7. The direction of the supply air flow is indicated by the solid arrows and the direction of the ambient air flow is indicated by the hollow arrows.
As shown in fig. 1 to 5, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10 and a plurality of air deflectors 50 arranged along a length direction of the casing 10 (i.e., a y direction indicated in fig. 1), for example, two air deflectors are provided in fig. 1. The air flow blown out from the inside of the casing 10 is the supply air flow. When the air conditioner is used for refrigerating, the air supply flow is cold air; when the air conditioner heats, the air supply flow is hot air. The plurality of air deflectors 50 are used to guide the air flow output from the casing 10. Each air deflector 50 corresponds to an area within the room, and each air deflector 50 is matched with one driving device 70 to be controlled independently. The air guide angles of the air guide plates are adjusted respectively, so that the air supply airflow can be adjusted in a partitioned mode, different requirements of users in different indoor areas are met, and the air supply control of the air conditioner is more refined. For example, as shown in fig. 1, the left air guiding plate can be used for blowing air upwards to the covered area, and the right air guiding plate can be used for blowing air downwards to the covered area. The wind guiding angle of each wind guiding plate 50 can be operated by a user, for example, by a remote controller. And a human body detection device can be arranged for detecting information such as the area where the human body is located, the surface temperature and the like, so that the controller can acquire the detection information and control the air deflector corresponding to the area according to a preset program, thereby realizing the air supply effects of directly blowing the human body by the air supply airflow, avoiding the human body and the like.
The number of the wind deflectors 50 may be two as shown in fig. 1 to 3. It is also possible to have three deflectors 50, as shown in fig. 7. Of course, the number of the air deflectors can also be four or more.
As shown in fig. 1 and 2, an air outlet 12 is formed on the housing 10 for outputting an air flow. A plurality of air deflectors 50 are provided at one air outlet 12. That is, one outlet 12 corresponds to a plurality of air deflectors 50. In some alternatives, a plurality of air outlets may be provided, such that each air outlet corresponds to one air deflector, or each air deflector corresponds to a plurality of air outlets.
As shown in fig. 2, the wall-mounted air conditioning indoor unit may include an evaporator 20, a blower 30, a duct 40, and a swing vane 60. The evaporator 20 is used for exchanging heat with air entering the housing 10 from the air inlet 11 to form a supply air flow. The inlet of the air duct 40 faces the evaporator 20, and the outlet communicates with the air outlet 12. The fan 30 may be a cross-flow fan disposed at an inlet of the air duct 40 to promote air flow from the evaporator 20 to the air outlet 12. The swing blade 60 is used for adjusting the left and right air outlet directions of the air outlet 12.
The structure of the air deflector in the wall-mounted air conditioner indoor unit will be described below.
As shown in fig. 2 to 5, the wind deflector 50 may generally include a wind deflector body 51 and a wind-raising portion 52. The air deflector body 51 is adapted to be rotatably mounted to the housing 10 (about the x-axis, which is shown in the figures). When the air deflector body 51 conducts air, the upward side thereof is the first side, and the surface thereof is the first side surface 511; the downward side is the second side, and its surface is the second side 512. The end of the air deflector body 51 near the upstream of the supply airflow is defined as the windward end (B end), and the end near the downstream of the supply airflow is defined as the air outlet end (a end). The flow direction of the blowing air flow on the first side surface 511 of the air deflector body 51 is towards the air outlet end.
The air blowing portion 52 protrudes from the first side surface 511 of the air deflector body 51 facing upward during air guiding, and is configured to guide the air flow away from the air deflector body 51 gradually to flow obliquely upward when the air flow passes through the first side surface 511. Therefore, the upward blowing angle (the included angle between the upward air outlet direction and the vertical direction) of the air supply flow is smaller, and the wall-mounted air conditioner indoor unit can realize better upward blowing so as to enable the air to better avoid the human body.
Furthermore, the utility model discloses aviation baffle can make wall-hanging air conditioner indoor set can compromise air-out angle and amount of wind. For example, in order to improve the air blowing comfort, when the wall-mounted air conditioning indoor unit cools, it is generally desirable that the air guide plate guides the cool air to blow out as vertically upward as possible. However, when the air deflector of the conventional wall-mounted air conditioner indoor unit rotates to an upward blowing angle close to the limit, the included angle between the air deflector and the plane of the air outlet is too small, that is, the opening degree is very small (the opening degree of the air deflector refers to the degree of opening the air outlet, and when the air deflector completely closes the air outlet, the opening degree is zero, when the air deflector completely opens the air outlet (refer to fig. 6), the opening degree is 100%, the air outlet is most smooth), the air deflector can seriously shield the air outlet, and the air volume becomes very small. This limits the wind guiding angle range of the wind guiding plate. Especially, when the air is guided vertically, the air guiding angle and the air volume are difficult to be considered simultaneously.
In the embodiment of the present invention, the wind raising portion 52 can raise wind to guide. Therefore, when the wall-mounted air conditioner indoor unit operates in a cooling mode, the air deflector body 51 does not need to be rotated to be in a state of being too close to the vertical state (namely, a state of closing the air outlet), so that the air deflector 50 is ensured to have a large enough opening degree, and the air volume is prevented from being influenced. Therefore, the wall-mounted air conditioner indoor unit has both air supply angle and air volume.
The utility model discloses only through add a portion 52 that rises wind on aviation baffle 50 and just realized the function of rising wind, the design is very ingenious, and the structure is very simple, and the cost is lower. In addition, other structures of the wall-mounted air conditioner indoor unit do not need to be changed, and the wall-mounted air conditioner indoor unit is very beneficial to mass production and popularization.
In some embodiments, as shown in fig. 2-5, the scoop 52 includes a scoop 521. The wind-raising plate 521 extends from the first side surface 511 toward the downstream direction of the blowing air flow and gradually away from the wind deflector body 51. That is, in a direction from upstream to downstream of the blowing air flow, the distance between the wind-up plate 521 and the first side surface 511 gradually increases, and the wind-up plate 521 gradually moves away from the wind deflector body 51 to smoothly guide the air flow to gradually move away from the wind deflector body 51.
The projection of the wind-lifting plate 521 on the first side 511 can be located within the range of the wind deflector body 51. In other words, the end (E end) of the wind-raising plate 521 is retracted a distance in the upstream direction of the blowing air flow compared with the wind-out end (a end) of the wind deflector body 51. It can also be understood that, by making a perpendicular line to the first side 511 of the deflector body 51 at the end of the deflector 521, the foot will fall on the first side 511 itself rather than on the extension of the first side 511. Thus, the contact between the air-lifting plate 521 and the upper edge of the air outlet 12 when the air-guiding plate body 51 closes the air outlet 12 can be avoided.
The wind-raising plate 521 can be a curved plate with a central axis parallel to the rotation axis of the wind deflector body 51 and a convex surface facing the wind deflector body 51, so as to better raise and guide the wind flow.
As shown in fig. 2 to 5, the air deflector body 51 is elongated in a direction parallel to the rotation axis thereof. The wind-raising plate 521 is a long strip extending along the length direction of the wind deflector body 51, and two ends of the wind deflector body 51 in the length direction have a distance from each other. That is, the length of the wind-lifting plate 521 is shorter than that of the wind deflector body 51, so that the two ends of the wind deflector body 51 in the length direction form a more unobstructed wind-discharging area, and the wind volume of the wind outlet 12 is increased. The length of the air deflector body 51 can be equal to the length of the casing 10 of the wall-mounted air-conditioning indoor unit, and is longer than the air outlet 12 (the length of the air outlet is shorter than the length of the casing), so that the two end sections of the air deflector body 51 cover the outer surface of the casing 10, and the appearance of the wall-mounted air-conditioning indoor unit is more beautiful. In addition, the entire air deflector body 51 may be a long arc plate with a concave first side surface 511. Of course, the entire air guide plate body 51 may be a flat plate.
As shown in fig. 3, the wind pumping part 52 may further include two end plates 523, and the two end plates 523 are respectively connected between two ends of the wind pumping plate 521 along the rotation axis direction of the wind deflector body 51 and the first side surface 511 to close a gap between the two ends of the wind pumping plate 521 and the first side surface 511. This prevents the air flow from flowing in the direction of the rotational axis of the air deflection plate body 51, thereby preventing the occurrence of adverse eddy currents and noise.
As shown in fig. 3 and 4, the wind-lifting portion 52 may further include a plurality of connection ribs 522 arranged at intervals along the parallel direction of the rotation axis of the wind deflector body 51, and each connection rib 522 connects the wind-lifting plate 521 and the wind deflector body 51 to realize the structural connection. The extending directions of the plurality of connection ribs 522 may be further parallel to the flowing direction of the supply air flow, so as to reduce the resistance of the connection ribs 522 to the air flow. The wind-raising portion 52 and the wind deflector body 51 can be an integral piece, so as to be convenient for processing and manufacturing.
In some embodiments, as shown in fig. 2 to 5, the air deflector body 51 is provided with a through flow guide opening 515, the flow guide opening 515 penetrates through two side surfaces of the air deflector body 51, and is located on a downstream side of the air flow relative to the wind blowing portion 52. After the air current flows through the wind-raising portion 52, a negative pressure is formed at the first side surface 511, so that the ambient air at the second side (lower side) of the air deflector body 51 is driven to flow into the air current through the drainage opening 515.
That is, since the wind-blowing portion 52 causes the blowing air flow to be away from the first side surface 511, the air flow density at the first side surface 511 of the air deflector body 51 is reduced, and a negative pressure region is formed (the S region in fig. 2 roughly indicates a negative pressure region range). Under the suction of the negative pressure region, the ambient air on the second side of the air deflector body 51 enters the negative pressure region through the drainage port 515 formed on the air deflector body 51, and then is converged into the air supply flow, so as to form an air mixing effect. When the air conditioner is used for refrigeration, ambient air is mixed into the air supply airflow, so that the temperature of the air supply airflow can be properly increased; when the air conditioner heats, the temperature of the air supply airflow can be properly reduced by mixing the ambient air, so that the air supply airflow is more comfortable, and the comfortable air supply of the air conditioner is realized.
The upstream edge of the flow guide opening 515 refers to the edge of the flow guide opening 515 close to the windward end of the air deflector body 51, and the other edge of the flow guide opening 515 opposite to the upstream edge (C edge) of the flow guide opening is the downstream edge (D edge) of the flow guide opening, as shown in fig. 4 and 5.
For the solution that the wind-lifting portion 52 includes the wind-lifting plate 521, the wind-lifting plate 521 may extend from the airflow upstream edge (C-side) of the flow guide opening 515. The projection of the air-lifting plate 521 on the first side 511 can at least cover the air-guiding opening 515, so that the problems that the ambient air directly enters the air supply airflow vertically through the air-guiding opening 515 to cause excessive noise and the like can be avoided. Further, the end (E-end) of the wind-lifting plate 521 in the airflow direction may be positioned beyond the drainage port 515 (referring to the edge D of the downstream airflow edge of the drainage port 515) to define a drainage channel 516 communicating with the drainage port 515 with the first side 511. The flow direction of the ambient air is guided by the flow guide 516 so that when the ambient air merges with the supply air, the two air streams have a smaller included angle and are mixed more gently.
In some embodiments, as shown in fig. 2 to 5, the air deflector 50 further includes at least one rotating arm 53 having one end connected to the driving device 70 located inside the casing 10 and the other end connected to the air deflector body 51. Under the driving of the driving device 70, the rotating arm 53 drives the air deflector body 51 to rotate around the first end of the rotating arm 53 upwards to close the air outlet 12, or rotate downwards to open the air outlet 12. A plurality of the rotation arms 53 may be provided such that the plurality of rotation arms 53 are arranged at intervals along the length direction of the air deflection body 51. The drive means 70 comprise an electric motor for directly or indirectly driving the rotation arm 53 in rotation.
As shown in fig. 6, the outlet 12 may be located at a lower portion of the front side of the housing 10 and opened forward and downward. The rotating arm 53 is a bent arm with a bent portion and a downward opening. The driving device 70 is installed at the bottom wall of the wind tunnel 40. The purpose of setting up the bent arm is: at each angle of the air deflector 50 opening the air outlet 12, the first side surface 511 faces the air outlet 12, so that the air flow is guided by the first side surface 511, and the second side surface 512 faces away from the air outlet 12 and contacts with the ambient air, thereby facilitating the realization of the air mixing function of the air deflector 50. Moreover, the curved arm is also convenient to rotate the air deflector body 51 to the lower side of the casing 10, so as to completely avoid the air flow blown out from the air outlet 12, i.e. completely open the air outlet 12, and make the air deflector 50 completely not block the air flow.
On the basis, one or more inner guide plates 80 may be further disposed at the air outlet 12, and the inner guide plates 80 are rotatably mounted at the air outlet 12 and located inside the air guide plate 50 for adjusting the up-down air outlet direction of the air outlet 12. That is, the air guide plate 50 performs more functions of opening and closing the air outlet and mixing the air, and the inner guide plate 80 performs the functions of guiding the air and swinging the air upward and downward.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described in detail herein, many other variations and modifications can be made, consistent with the principles of the invention, which are directly determined or derived from the disclosure herein, without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and interpreted to cover all such other variations or modifications.
