Those of ordinary skill in the art will understand the specific meaning of the terms described above in the present utility model as the case may be.
The utility model provides a wall-mounted air conditioner indoor unit. The indoor unit of the wall-mounted air conditioner is an indoor unit of a split air conditioner or an indoor terminal unit of a central air conditioner, and is used for adjusting indoor air, such as refrigeration/heating, dehumidification, fresh air introduction and the like. The indoor unit of the wall-mounted air conditioner is an indoor part of a split wall-mounted air conditioner or an indoor tail end machine type of a central air conditioner, and the air conditioner can form a vapor compression refrigeration cycle system by an evaporator, a condenser, a compressor, a throttling device and other necessary elements so as to output cold air/hot air through a fan 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 utility model; FIG. 2 is an enlarged cross-sectional view of the wall-mounted air conditioner indoor unit of FIG. 1 taken in a vertical plane extending back and forth; fig. 3 is an exploded view of the housing 10 and the air intake fan 60 in the wall-mounted air conditioner indoor unit shown in fig. 1. The flow direction of the air flow is indicated by arrows in fig. 2.
As shown in fig. 1 to 3, the wall-mounted air conditioner indoor unit according to the embodiment of the present utility model may generally include a housing 10, an evaporator 20, and at least one air intake fan 60.
The casing 10 defines an accommodating space in which main components of the wall-mounted air conditioner indoor unit are accommodated. For example, as shown in fig. 2, the inside of the housing 10 is provided with an evaporator 20 and a blower 30. Under the action of the blower 30, indoor air is sucked into the interior of the housing 10, forms heat exchange air into the air duct 15 after forced convection heat exchange with the evaporator 20 is completed, and is then blown into the room through the air outlet 12 of the housing 10 to regulate the indoor air. The fan 30 is preferably a cross-flow fan with its axis parallel to the length direction of the housing 10, which is provided at the inlet of the air duct 15. The evaporator 20 may be a three-stage evaporator. An air deflector 50 may be provided at the air outlet 12 for adjusting the air outlet direction and for closing the air outlet 12.
The casing 10 has a front wall 101, and the front wall 101 constitutes the front appearance of the wall-mounted air conditioner indoor unit. That is, the front surface of the wall-mounted air conditioner indoor unit, i.e., the outer side surface of the front wall 101, as viewed by the user. The front wall 101 is provided with at least one air inlet opening 13. The evaporator is disposed within the housing 10.
Each air inlet fan 60 is mounted at one air inlet opening 13. That is, the number of the air intake fans 60 is the same as that of the air intake holes 13, and the corresponding pairs are provided. The air intake fan 60 serves to force indoor air into the interior of the housing 10 to exchange heat with the evaporator 20.
In the wall-mounted air conditioner indoor unit in the prior art, only the top wall of the shell is provided with the air inlet, but the top of the shell is very close to the ceiling, so that the air inlet space is narrow, and the air inlet quantity is not affected little. In the embodiment of the utility model, the front wall 101 of the casing 10 is provided with the air inlet hole 13, so that indoor air in front of the casing 10 can be sucked, and the air inlet is smooth and has larger air inlet quantity because no obstacle is usually arranged in front of the casing 10.
In addition, the air inlet hole 13 is provided with an air inlet fan 60, and after the air inlet fan 60 is started, the air inlet quantity can be further increased. The increased air intake volume results in higher heat exchange efficiency of the evaporator 20 and thus higher cooling/heating capacity. And the air intake can be adjusted by changing the number and rotation speed of the air intake fans 60. After the air intake fan 60 is turned on, the airflow is accelerated, and the load of the fan 30 in the original duct 15 can be reduced. Alternatively, the blower 30 can be designed smaller.
In some embodiments, as shown in fig. 1-3, the housing 10 further includes a top wall 102 that forms an upper appearance thereof. The top wall 102 may also be provided with an air inlet 11 to allow indoor air to enter the housing 10 through the air inlet 11 for heat exchange with the evaporator 20. That is, in this embodiment, the air inlet opening 13 is newly added, and the air inlet 11 at the top of the housing 10 is reserved, so that the air inlet amount is larger.
In some embodiments, as shown in fig. 1 to 3, the number of the air inlet holes 13 may be plural, and the plurality of air inlet holes 13 may be arranged at intervals along the lateral direction of the housing 10. The design can improve the adjustability of the air inlet quantity. For example, only one air intake fan 60 is turned on, two air intake fans 60 are turned on, or three air intake fans 60 are turned on, and the variation in the intake air amount is relatively large.
Also, each of the air inlet holes 13 may be made circular. A safety distance is reserved between the periphery of the air inlet fan 60 and the edge of the air inlet hole 13, but the safety distance is as small as possible, so that a visual effect that the air inlet fan 60 is embedded in the air inlet hole 13 is formed. The circular air inlet holes 13 which are transversely arranged also enable the appearance of the wall-mounted air conditioner indoor unit to be more unique and attractive.
In some embodiments, as shown in fig. 1-3, each air intake fan 60 is an axial flow fan. Axial fans are lower cost and adequate to meet air intake demands. In addition, the fan blades 61 of each air intake fan 60 may be elongated, one end of the fan blade 61 in the length direction is connected to the hub of the fan, and each fan blade 61 is driven by the motor to rotate, so as to promote the indoor air flow into the housing 10. It is preferable to make the number of the blades 61 larger than 18, and to arrange so many blades 61 that the blades 61 are arranged very densely. During the air conditioning shutdown, the air inlet fan 60 can block the air inlet hole 13 to the greatest extent, and a great deal of dust is prevented from entering the shell 10 through the air inlet hole 13. And the fan blades 61 are densely arranged, so that the air inlet fan 60 can be flattened, the thickness space of the shell 10 occupied by the air inlet fan is smaller, and the influence on flattening of the wall-mounted air conditioner indoor unit is avoided.
In some embodiments, as shown in fig. 2, the front of the evaporator 20 is spaced from the front wall 101 to allow the flow of inlet air to pass through the evaporator 20 from the front of the evaporator 20, so as to be spaced from the flow of inlet air of the inlet air 11.
FIG. 4 is an enlarged view at A of FIG. 3; FIG. 5 is a schematic view of the housing 10 of FIG. 4 from the back perspective; fig. 6 is an enlarged view at B of fig. 5.
In some embodiments, as shown in fig. 4 to 6, a bracket 14 is provided at each air inlet 13, and the bracket 14 is connected to the inner side surface of the front wall 101 for mounting the air inlet fan 60.
Specifically, each bracket 14 includes a support rod 141 and a connection rod 142 bent and extended from both ends of the support rod 141 to connect the inner side of the front wall 101. The middle part of the supporting rod 141 extends out of a mounting hole 143, and the mounting hole 143 is used for mounting the air inlet fan 60. Each bracket 14 is preferably formed as an integral piece with the front wall 101.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been shown and described herein in detail, many other variations or modifications of the utility model consistent with the principles of the utility model may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the utility model. Accordingly, the scope of the present utility model should be understood and deemed to cover all such other variations or modifications.
