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 air conditioner and is used for adjusting indoor air, including adjusting the temperature, humidity and air quality of the air, humidifying the indoor air, dehumidifying, introducing fresh air and the like. The air conditioner can form a vapor compression refrigeration cycle system by an indoor side heat exchanger, an outdoor side heat exchanger, a compressor, a throttling device and other necessary elements, so as to output cold air/hot air through a wind wheel and realize refrigeration and heating of an indoor environment.
Fig. 1 is a schematic structural view of an indoor unit of a wall-mounted air conditioner according to an embodiment of the present invention; FIG. 2 is a schematic view of the wall-mounted air conditioner indoor unit of FIG. 1 after concealing the air deflector and air deflector; fig. 3 is a schematic view of the wall-mounted air conditioner indoor unit shown in fig. 1 after cutting out a partial area of the casing.
As shown in fig. 1 to 3, the wall-mounted air conditioner indoor unit according to the embodiment of the present invention may generally include a housing 10, a heat exchanger 30, and a first wind wheel 40.
The housing 10 defines a structural body of the wall-mounted air conditioner indoor unit, and defines an accommodating space to accommodate main body components of the wall-mounted air conditioner indoor unit, such as the heat exchanger 30, the first wind wheel 40, the controller, and the like. The housing 10 may be elongated in a horizontal transverse direction along a length direction (x-direction). The housing 10 is provided with an air inlet 11 for sucking in indoor air. The housing 10 defines a main duct 15 therein, the main duct 15 having an air outlet 12 facing the indoor environment. The volute 152, volute tongue 151, etc. defining the main air duct 15 may be an integral piece with the remainder of the housing 10. Of course, it may be a separate component that is fabricated separately. In some embodiments, as shown in fig. 3, the air inlet 11 may be disposed at the top of the housing 10, and the air outlet 12 may be disposed at the front lower portion of the housing 10.
The heat exchanger 30 is disposed in the housing 10, and is configured to exchange heat with an air flow entering the housing 10 from the air inlet 11 to form a heat exchange air flow. The heat exchanger 30 may be a three-stage heat exchanger, with its opening facing downward and covered at the inlet of the main air duct 15 (refer to fig. 6). The heat exchanger 30 may be an indoor side heat exchanger of a vapor compression refrigeration cycle system.
The first wind wheel 40 is used for forcing the heat exchange air to flow through the main air duct 15 and blow out of the air outlet 12, so that the heat exchange air flow is blown out to the indoor environment through the air outlet 12, and the temperature of the indoor environment is regulated. The first wind wheel 40 may be a cross-flow wind wheel with an axis extending in the transverse direction (x direction), and may be disposed at an inlet of the main air duct 15, as shown in fig. 2 and 6. Of course, the first wind wheel may be a centrifugal wind wheel, an axial flow wind wheel, or other forms.
As shown in fig. 3, the lateral end surface 31 of the heat exchanger 30 (which may be an outer surface of an end plate of the fin type heat exchanger) and the lateral end wall 153 of the main air duct 15 are spaced from one end cover 101 in the lateral direction of the housing 10 to constitute a non-heat exchanging space 16. As will be appreciated by those skilled in the art. In order to reserve installation space for the structures such as the pipelines at the side ends of the heat exchanger 30 and the rotating shaft of the first wind wheel 40, the heat exchanger 30 and the transverse end wall 153 of the main air duct 15 cannot be attached to the end cover 101 of the casing 10, and the non-heat exchange space 16 is necessarily formed. When the wall-mounted air conditioner indoor unit is in operation, heat exchange air is guided by the main air duct 15 and blown to the indoor environment through the air outlet 12, and cannot flow through the non-heat exchange space 16, so that the heat exchange air is a cooling and heating blind area. When the wall-mounted air conditioner is used for cooling, the non-heat exchange space 16 is free from inflow of cold air, and hot air is deposited, so that condensation is easily avoided in the space.
For this reason, the wall-mounted air conditioner indoor unit of the embodiment of the invention is configured to: a part of the heat exchange air flow in the main air duct 15 is introduced into the non-heat exchange space 16. During air conditioning refrigeration, the introduction of cold air flow can effectively avoid the accumulation of hot air in the non-heat exchange space 16, thereby avoiding the condensation of the wall surface in the space. It will be appreciated that the non-heat exchanging space 16 is not isolated from the rest of the housing 10, so that the air flow in the non-heat exchanging space 16 can be discharged through other gaps or intervals while the heat exchanging air flows in, thereby realizing the circulation of the air flow.
Fig. 4 is a schematic view of the bypass duct 70, and fig. 5 is a schematic view of the bypass duct 70 and the second wind wheel 703;
in some embodiments, as shown in fig. 2-5, the wall-mounted air conditioner indoor unit further includes a bypass duct 70. The bypass duct 70 has an air suction port 71 connected to the bypass outlet 155 of the main duct 15 and an air discharge port 72 communicating with the non-heat exchanging space 16 to introduce the heat exchanging air flow into the non-heat exchanging space 16.
When the wall-mounted air conditioner indoor unit is operated, most air in the main air duct 15 flows through the air outlet 12 to be blown to the indoor environment, and the small air flows into the bypass air duct 70 through the bypass outlet 155 and then enters the non-heat exchange space 16 from the air outlet 72 of the bypass air duct 70. Fig. 4 illustrates a state in which the bypass duct 70 is detached from the inside of the housing 10. Of course, the bypass duct 70 may be formed integrally with the adjacent portion of the housing 10.
Further, the wall-mounted air conditioner indoor unit further comprises a second wind wheel 703. The second wind wheel 703 is disposed in the bypass duct 70. The second wind wheel 703 can be controllably opened to introduce a heat exchange air flow into the non-heat exchange space 16, thereby ensuring that a sufficient cool air flow is introduced.
Specifically, as shown in fig. 4 and 5, the second wind wheel 703 is a cross-flow wind wheel whose axis extends in the lateral direction of the housing 10, and the bypass duct 70 is a cross-flow duct accordingly. The motor 702 of the second wind wheel 703 is disposed outside the bypass air duct 70, and its rotation shaft extends into the bypass air duct 70 through a hole 705 in the wall of the bypass air duct 70 to drive the second wind wheel 703 to rotate. This prevents the motor 702 from obstructing the flow of the airflow.
Of course, in some alternative embodiments, the second wind wheel 703 may also be a centrifugal wind wheel with an axis extending in a lateral direction of the housing 10.
Further, the wall-mounted air conditioner indoor unit may further include a first temperature sensor 91 and a second temperature sensor 92. The first temperature sensor 91 is used to detect the coil temperature of the heat exchanger 30, see fig. 6. The second temperature sensor 92 is used to detect the temperature of the air within the non-heat exchanging space 16. The wall-mounted air conditioning indoor unit is configured to control the operating state of the second wind wheel 703 according to the difference between the coil temperature and the air temperature. Specifically, the second wind wheel 703 may be controlled by a main control board of the air conditioner.
An alternative control method is as follows: when the temperature difference is greater than the preset difference during the air-conditioning cooling operation, the second wind wheel 703 is controlled to be turned on. And controlling the second wind wheel 703 to be closed until the temperature difference is less than or equal to the preset difference. Therefore, the quantity of the cold air flow introduced can just meet the requirement of condensation prevention, and excessive cold air flow is prevented from being introduced when the requirement of condensation prevention is not met, or enough cold air flow is not introduced when the requirement of condensation prevention is large.
Fig. 6 is a schematic cross-sectional view of a wall-mounted air conditioning indoor unit according to one embodiment of the present invention when the wind deflector 51 is at a wind storage angle; fig. 7 is a schematic view of the wall-mounted air conditioner indoor unit shown in fig. 6 when the wind deflector 51 is rotated away from the wind storage angle.
In some embodiments, as shown in fig. 2 and 6, the main air duct 15 may be defined by a volute tongue 151, a volute 152, and two lateral end walls 153. In the embodiment in which the air outlet 12 is opened at the front lower portion of the casing 10, the volute tongue 151 is located in front of the volute 152. The bypass outlet 155 opens onto the transverse end wall 153.
The inventor has realized that under the action of the first wind wheel 40, the heat exchange air flow directly rushes out of the air outlet 12 along the main air duct 15, and the bypass outlet 155 is arranged on the transverse end wall 153 of the main air duct 15, the opening direction is perpendicular to the air flow direction, and the air flow cannot be directly rushed in, so that the ventilation amount of the bypass outlet 155 is not large, and the condensation prevention requirement may be difficult to meet.
To this end, in some embodiments, as shown in fig. 6 and 7, the wall-mounted air conditioning indoor unit further includes a wind deflector 51. The wind deflector 51 is rotatably mounted at the air outlet 12 about a transverse axis. And, the wind guard 51 has a wind storage angle that is overlapped with the surface of the scroll 152 or the scroll 151, as shown in fig. 6, so as to form a wind storage space 150 with the scroll 152 or the scroll 151. The bypass outlet 155 communicates with the air reservoir 150. During the indoor refrigeration operation of the wall-mounted air conditioner, the cold air flow stays and gathers, so that enough cold air flow is ensured to enter the non-heat exchange space 16.
In the embodiment illustrated in fig. 6, the wind deflector 51 is disposed adjacent to the volute 152 so as to form a wind storage space 150 with the volute 152. It will be appreciated that the wind deflector 51 may also be positioned adjacent the volute tongue 151 to form a wind reservoir with the volute 152.
Further, as shown in fig. 6, the lower end of the wind deflector 51 abuts against the outlet end of the scroll casing 152 when at the wind storage angle. In this way, the air storage space 150 is a triangular space with an upper portion opened. When the main fan is operated, the heat exchange air flow flows forward and downward, and does not strongly impact the air storage space 150. As shown in fig. 2 and 6, the bypass outlet 155 may be formed in a triangular shape corresponding to the shape of the air storage space 150.
Further, as shown in fig. 6, the volute 152 includes a main body section 1521 (AB-section) and an outlet section 1523 (BC-section) extending from a lower end B of the main body section 1521 (AB-section) in a downward bent manner, and the outlet section 1523 is configured to define the air storage space 150 with the wind deflector 51. This arrangement allows the air storage space 150 to be deeper and narrower to store the cool air flow.
In some embodiments, as shown in fig. 6 and 7, the wall-mounted air conditioner indoor unit further includes an air deflector 52. The air deflector 52 is rotatably mounted at the air outlet 12 about a transverse axis for guiding the air outlet direction at the air outlet 12. When the wind deflector 51 is at the wind storage angle, the upper end of the wind deflector 51 can be made to abut against the surface of the wind deflector 52, as shown in fig. 6. When condensation prevention is not needed, for example, when a wall-mounted air conditioner is used for indoor heating operation, the wind deflector 51 can be used for guiding wind so as to be equivalent to another wind deflector, as shown in fig. 7.
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.
