However, in order to achieve more rapid cooling and heating, it is unavoidable to perform large-volume air blowing. However, when cold air or hot air having an excessive wind speed is directly blown to the human body, discomfort of the human body is necessarily caused. The human body can be directly blown by cold air for a long time to cause air conditioning diseases.
Therefore, how to realize comfortable air supply of the air conditioner becomes a technical problem to be solved in the air conditioning industry.
Disclosure of Invention
It is an object of the present invention to provide a wall-mounted air conditioning indoor unit that overcomes or at least partially solves the above-mentioned problems.
The invention aims to improve the air outlet effect of an indoor unit of a wall-mounted air conditioner.
A further object of the present invention is to enrich the air output and the regulation pattern of the air output direction.
In particular, the present invention provides a wall-mounted air conditioner indoor unit comprising:
a housing defining an air outlet opening toward the front lower side; and
the air guide plates are rotatably arranged at the air outlet and are in a closed state to shield the air outlet or in an open state to guide the air outlet direction of the air outlet, the surface of each air guide plate facing the inner side of the shell when in the closed state is an air guide surface, and the front end of each air guide plate is an air outlet end when the air guide surface faces upwards; and is also provided with
Each air deflector is provided with a plurality of ventilation holes, when the air deflector is in the closed state, at least part of the axial direction of the ventilation holes is inclined forwards and upwards, the air guiding surface is provided with a plurality of protruding parts, and each protruding part is positioned at the edge of one air ventilation hole inlet, which is closer to the air outlet end.
Optionally, each air deflector is in a strip shape with a length direction parallel to the length direction of the shell, and at least part of the air permeable holes are strip holes with a length direction parallel to the length direction of the air deflector; and is also provided with
Each protruding portion is in a long strip shape extending along the length direction of the ventilation hole.
Optionally, the cross-section external contour of the protruding portion is arc-shaped.
Optionally, the lobe cross-section outer profile radius is between 0.5mm and 1 mm.
Optionally, the circular arc central angle of the cross section outer contour of the protruding part is larger than or equal to 180 degrees.
Optionally, the length of the long strip-shaped ventilation hole is between 25mm and 30mm, and the width is between 2mm and 3 mm.
Optionally, the other surface of each air deflector, which faces away from the air guiding surface, is a non-air guiding surface; and the inner wall of each ventilation hole, which is closer to the air outlet end, and the non-air guiding surface of the air guide plate adopt fillet transition.
Optionally, the plurality of ventilation holes are arranged on a half part of the air deflector adjacent to the air outlet end.
Optionally, when the air deflector is in the closed state, at least part of the axial direction of the air permeable holes is inclined upwards, and the elevation angle is between 28 ° and 32 °.
Optionally, the number of the air deflectors is two, and the air deflectors are arranged along the width direction of the air outlet; and when the two air deflectors are in the closed state, a gap for air outlet is arranged between the air deflector positioned at the lower side and the lower edge of the air outlet.
In the wall-mounted air conditioner indoor unit, a plurality of ventilation holes are formed in an air deflector. When the air deflector is in a closed state, at least part of the axial direction of the air permeable holes is inclined forwards and upwards, so that the air deflector in the closed state can also lift air. Therefore, when comfortable air supply is needed, the air deflector can be in a closed state, so that heat exchange air flow is blown out from the air-permeable holes, the air flow impact force is smaller, the indoor air feeling is more comfortable, the air flow flows upward, and the human body can be avoided. Because the air outlet faces downwards and forwards, when the air deflector is in a closed state, the air deflector surface of the air deflector gradually inclines upwards from back to front. Based on the above, the invention particularly makes the edge of the ventilation hole close to the air outlet end provided with the bulge part, and after part of air flow impacts the bulge part, the coanda effect is generated (when the surface friction exists between the fluid and the surface of an object through which the fluid flows, so to speak, when the fluid viscosity is generated, the fluid flows along the surface of the object as long as the curvature is not large), and the fluid flows upwards along the surface of the bulge part, so that the air flow is blown out from the ventilation hole on the upper side more, and the personal avoiding effect of the air flow is better.
Furthermore, in the wall-mounted air conditioner indoor unit, the inner wall of the outlet of the ventilation hole, which is closer to the air outlet end, and the non-air-guiding surface of the air deflector are in rounded transition, so that after the air flow flows out of the ventilation hole, the coanda effect is generated on the surface of the rounded corner, the air flow can be further guided to flow obliquely upwards, and the upward air supply effect is improved.
In the wall-mounted air conditioner indoor unit, the plurality of ventilation holes are formed in the half part of the air guide plate adjacent to the air outlet end, and when the air guide plate guides air, part of air flow is guided by the non-perforated area (the half part of the air guide plate close to the air inlet end), the flowing direction is basically shaped, and the direction does not change greatly after passing through the perforated area. Therefore, the air deflector can not be excessively damaged in direction guiding function due to the fact that too many ventilation holes are formed.
The above, as well as additional objectives, advantages, and features of the present invention will become apparent to those skilled in the art from the following detailed description of a specific embodiment of the present invention when read in conjunction with the accompanying drawings.

The embodiment of the invention provides a wall-mounted air conditioner indoor unit. The wall-mounted air conditioner indoor unit is an indoor part of a split wall-mounted room air conditioner and is used for adjusting indoor air, such as refrigeration/heating, dehumidification, fresh air introduction and the like.
Fig. 1 is a schematic front view of a wall-mounted air conditioning indoor unit according to one embodiment of the present invention; FIG. 2 is an enlarged view of a section C-C of the wall-mounted air conditioner indoor unit of FIG. 1; fig. 3 is an enlarged schematic view of the air deflector 50 in the wall-mounted air conditioner indoor unit shown in fig. 2. The flow direction of the air flow is schematically indicated by arrows; fig. 4 is a schematic view of the wall-mounted air conditioner indoor unit shown in fig. 2 when the two air deflectors 50 are rotated to the front air guiding position.
As shown in fig. 1 to 4, the wall-mounted air conditioner indoor unit according to the embodiment of the present invention may generally include a housing 10 and at least one air guide 50. The casing 10 is provided with an air outlet 12 which is opened forward and downward. The housing 10 defines an accommodating space for accommodating components of the wall-mounted air conditioner indoor unit. The air outlet 12 may be opened at a front lower portion of the housing 10 so as to be opened forward and downward. The air outlet 12 is used to discharge the air flow in the housing 10 to the indoor environment to condition the indoor air. The discharged air flow refers to an air flow that is acted on by a fan in the case 10 to accelerate the flow of air flowing through the air outlet 12 for adjusting the indoor environment, such as cool air in a cooling mode, hot air in a heating mode, fresh air in a fresh air mode, and the like. The housing 10 may be in the form of an elongated shape with a horizontal arrangement in the length direction, as shown in fig. 1. The air outlet 12 may be elongated with a length direction parallel to the length direction of the housing 10.
Each air deflector 50 of the embodiment of the present invention is rotatably disposed at the air outlet 12 to be in a closed state to block the air outlet 12 (as shown in fig. 2) or in an open state to guide the air outlet direction of the air outlet 12 (as shown in fig. 4). The number of the air deflectors 50 may be one or more. When a plurality of air deflectors 50 are arranged, each air deflector 50 is provided with a motor, and the operation is independently controlled. For example, as shown in fig. 2, two air deflectors 50 may be provided, and the two air deflectors 50 may be arranged in the width direction of the air outlet 12 such that the rotation axes X1 and X2 of the two air deflectors are parallel to the longitudinal direction of the air deflectors 50.
The surface of each air deflector 50 facing the inner side of the housing 10 when in the closed state is an air guiding surface 501, the other surface facing away from the air guiding surface 501 (i.e., the surface of the air deflector 50 facing the outer side of the housing 10 when in the closed state) is an air guiding surface 501 of a non-air guiding surface 502, and the forward end is an air outlet end (end a) and the rearward end is an air inlet end (end B) when the air guiding surface 501 is in the upward state (see fig. 4). In the air guide state in which the air guide surface 501 faces upward, the airflow main body flows from the air inlet end B toward the air outlet end a. Each air guide plate 50 is provided with a plurality of air-permeable holes 51, and when the air guide plate 50 is in a closed state, at least part of the axial direction of the air-permeable holes 51 is inclined forward and upward. At least partially refers to a portion or all. As shown in fig. 3, it is preferable that the axial direction of all the ventilation holes 51 be inclined upward and forward. Preferably, when the air guide plate 50 is in the closed state, the elevation angle a of the axial direction of the ventilation hole 51 inclined forward and upward in the axial direction is between 28 ° and 32 °, preferably between 29 ° and 31 °, and both the blow-through preventing effect and the blowing distance can be simultaneously achieved. The air guiding surface 501 has a plurality of protrusions 53, and each protrusion 53 is located at an edge (i.e., an upper edge) of the inlet of one of the air holes 51, which is closer to the air outlet end a, as shown in fig. 3.
In the wall-mounted air conditioner indoor unit provided by the embodiment of the invention, when comfortable air supply is needed, the air guide plate 50 can be in a closed state, so that heat exchange air flow is blown out from the air ventilation holes 51, the air flow impact force is smaller, the indoor air feeling is more comfortable, the air flow is upward and flows, and the human body can be avoided. Since the air outlet 12 is directed downward and forward, when the air deflector 50 is in a closed state, the air guiding surface 501 thereof is gradually inclined upward from the rear to the front as shown in fig. 2. Based on this, in the embodiment of the present invention, the edge of the ventilation hole 51 near the air outlet end a is provided with the protruding portion 53, and after a part of the airflow impacts on the protruding portion 53, the coanda effect is generated (when there is surface friction between the fluid and the surface of the object through which the fluid flows, it can be said that the fluid viscosity is generated, as long as the curvature is not large, the fluid flows along the surface of the object), and the airflow further flows upward along the surface of the protruding portion 53, so that the airflow is blown out from the ventilation hole 51 on the upper side, and the personal avoiding effect of the airflow is better.
In some embodiments, as shown in fig. 1 to 4, each air deflector 50 may be elongated with a length direction parallel to the length direction of the housing 10, and at least a portion of the air permeable holes 51 may be elongated holes with a length direction parallel to the length direction of the air deflector 50. The long hole means that the entire shape of the ventilation hole 51 is long, and is not limited to a rectangle or a rounded rectangle. Each of the protrusions 53 is elongated and extends in the longitudinal direction of the ventilation hole 51. The air deflector 50 according to the embodiment of the present invention is not a conventional microporous air deflector, and the effect of the ventilation holes 51 is not simply achieved, but the air flow is upwards guided. Therefore, the ventilation holes 51 are designed to be long, so that the ventilation holes have two long upward hole walls, and upward wind guiding can be better realized.
Further, as shown in fig. 3, the cross-sectional outer contour of the protruding portion 53 is preferably formed in an arc shape, which is advantageous in that the shape is more rounded, and in that the coanda effect is more easily formed, and in that the processing and the manufacturing are facilitated. The cross-sectional outer contour radius R1 of the boss 53 may be further set to be between 0.5mm and 1mm, preferably between 0.6mm and 0.9 mm. The circular arc central angle of the outer contour of the cross section of the protruding portion 53 may be made to be greater than or equal to 180 °. The outer contour of the raised portion 53 of this shape results in better coanda effect and less airflow loss.
In some embodiments, referring to fig. 1 and 3, the length L of the elongated vent holes 51 may be between 25mm and 30mm, more preferably between 26mm and 29 mm. The width d of the ventilation holes 51 is between 2mm and 3mm, more preferably between 2.2mm and 2.8 mm. Thus, not only the requirement of the ventilation air quantity of the ventilation holes 51 is met, but also the rigidity requirement of the air deflector 50 is met, and the air guiding function of the air deflector 50 is prevented from being excessively influenced due to the fact that the ventilation holes 51 are too large.
In some embodiments, as shown in fig. 1 to fig. 4, a rounded corner (R2) is adopted between the inner wall of each ventilation hole 51, which is closer to the outlet end a, and the air guiding surface 501 of the non-air guiding surface 502 of the air guiding plate 50, and after the air flows out of the ventilation holes 51, a coanda effect is generated on the rounded corner surface, which can further guide the air flow to flow obliquely upwards, so as to improve the upward blowing effect.
In some embodiments, the aforementioned plurality of ventilation holes 51 are provided in a half of the air deflector 50 adjacent to the air outlet end a. Thus, when the air deflector 50 guides air, part of air flow is guided by the non-perforated area (the half of the air deflector 50 near the air inlet end B), the flow direction is basically shaped, and then the direction is not greatly changed when the air deflector passes through the perforated area. In this way, the air guide plate 50 is not excessively damaged in the direction guiding function due to the provision of too many air-permeable holes 51.
In some embodiments, as shown in fig. 2, for the embodiment in which two air deflectors 50 are provided, when both air deflectors 50 are in the closed state, a gap (BN) for air outlet is provided between the air deflector 50 located at the lower side and the lower edge (N) of the air outlet 12, so that when the air deflector 50 is in the closed state shown in fig. 2, the air flow is divided into two upper and lower flows, and the upper air flow is blown up under the guidance of the ventilation holes 51 of the air deflector 50. The lower strand is blown downwards through the gap between the air deflector 50 and the lower edge of the air outlet 12. Therefore, the effect of preventing direct blowing wind can be realized, upward and downward bi-directional wind can be formed, surrounding airflow is formed, indoor air heat exchange is facilitated, and comfort is improved
As shown in fig. 2, in the embodiment of the present invention, the indoor unit of the wall-mounted air conditioner may be an indoor portion of a split wall-mounted room air conditioner for cooling/heating by using a vapor compression refrigeration cycle system. The inside of the housing 10 is provided with a heat exchanger 30 and a blower 40. The heat exchanger 30 and the throttle device are connected with a compressor, a condenser and other refrigerating elements arranged in the air conditioner outdoor unit through pipelines to form a vapor compression refrigerating cycle system. Under the action of the fan 40, indoor air enters the interior of the shell 10 through the air inlet 11 at the top of the shell 10, and after forced convection heat exchange with the heat exchanger 30 is completed, heat exchange air is formed, and then the air is blown to the air outlet 12 under the guidance of the air duct 20. The fan 40 is preferably a cross-flow fan with its axis parallel to the length direction of the housing 10, which is disposed at the inlet of the air duct 20. The heat exchanger 30 may be a three-stage heat exchanger.
Fig. 5 is a schematic view of the indoor unit of the wall-mounted air conditioner shown in fig. 2 when the two air deflectors 50 are rotated to the lower air guiding position; fig. 6 is a schematic view of the indoor unit of the wall-mounted air conditioner shown in fig. 2 when the two air deflectors 50 are rotated to the maximum air guiding position. The embodiment of the invention has a plurality of air supply modes; fig. 7 is a schematic fluid simulation diagram of an embodiment of the present invention for a wall-mounted air conditioner indoor unit in a direct blowing prevention mode.
As shown in fig. 2, the wall-mounted air conditioner indoor unit can operate in a direct blowing prevention mode. The air guide plates 50 are closed, and the air flow is blown out through the air holes 51 of the air guide plate 50 and the gap between the lower air guide plate 50 and the lower edge of the air outlet 12, and the result is referred to the simulation effect diagram of fig. 7.
As shown in fig. 4, the wall-mounted air conditioner indoor unit may operate in a front blowing mode. The two air deflectors 50 are rotated to a front air guiding position with the air guiding surface 501 facing upward and the air outlet end a facing forward, so as to guide the air flow of the air supply forward or upward. When the air conditioner is in refrigeration operation, the front blowing mode can be selected to supply air, so that the air flow of the supplied air is diffused faster, the air supply height is higher, and the shower type refrigeration experience is formed.
As shown in fig. 5, the wall-mounted air conditioning room can also operate in a submerged air supply mode. Each air deflector 50 is rotated to a lower air guiding position with the air guiding surface 501 facing forward and the air outlet end a facing downward, so as to better guide the air downwards. When the air conditioner is in heating operation, the sinking air supply mode can be operated, so that the hot air flows upwards after sinking to the ground, a carpet type heating effect is formed, and poor heating effect at the bottom of an indoor space is avoided.
As shown in fig. 6, the wall-mounted air conditioner indoor can also operate in a maximum air supply mode. The air deflector 50 rotates to gradually incline downwards from back to front, so that the width direction of the air deflector is just along the air flow direction, the resistance to the air flow is minimum, the air outlet is smoother, and the air quantity is maximum.
Of course, the above-described air supply modes are only examples, and the wall-mounted air conditioner indoor unit is not limited to only these air supply modes. The air conditioner can be automatically adjusted or used for controlling ground according to the indoor working condition, and the air deflector 50 is rotated to other angles, so that other air supply effects are realized.
By now 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 herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
