Detailed Description

The present utility model provides an air conditioner indoor unit, fig. 1 is a schematic structural diagram of an air conditioner indoor unit according to one embodiment of the present utility model, fig. 2 is a schematic structural exploded view of an air conditioner indoor unit according to one embodiment of the present utility model, and fig. 3 is a schematic structural diagram of an air conditioner indoor unit according to one embodiment of the present utility model after a part of the structure is hidden. Referring to fig. 1 to 3, an air conditioning indoor unit 1 may generally include a cabinet 10, an air flow driving device 20, and an air deflection assembly 30. The air deflection assemblies 30 are hidden from view in fig. 3 for more clarity of viewing the structure within the enclosure 10.

The casing 10 is provided with an air outlet 11 to allow air flow therein to flow out through the air outlet 11. Further, the casing 10 is further provided with an air inlet for allowing indoor air to enter the casing 10.

The airflow driving device 20 is disposed in the casing 10 and configured to controllably promote airflow in the casing 10 to be sent out through the air outlet 11.

The air deflection assembly 30 is disposed at the air outlet 11 for controllably opening and/or closing the air outlet 11 and controllably adjusting the air outlet direction of the air outlet 11 when the air outlet 11 is opened.

In particular, the indoor unit 1 further includes a plurality of fans 40, and the plurality of fans 40 are disposed inside the air outlet 11 in a dispersed manner to blow off the air flow blown toward the air outlet 11.

The air conditioning indoor unit 1 of the present utility model has not only the conventional air flow driving device 20 and the air deflection assembly 30 to ensure a large air supply speed and a wide range of air supply angles, but also is particularly provided with a plurality of fans 40. The fans 40 can blow off the air flow blown to the air outlet 11 and soften the air, so that the air flow blown out by the air conditioner indoor unit 1 is cool but not cool, warm but not dry, and the air supply comfort is improved.

Meanwhile, the plurality of fans 40 are arranged in a dispersed manner, so that the air flow blown to the air outlet 11 is uniformly blown, and uniform air supply of the air outlet 11 is realized.

Based on the structural form of the fan 40, no matter what type of fan is selected, no obvious obstruction is generated to the air flow flowing through the fan, and therefore, the arrangement of the fan 40 does not adversely affect the air supply distance of the air conditioner indoor unit 1.

Since the fan 40 is disposed inside the air outlet 11 and is not exposed to the outside, the user hardly sees the fan 40, and the disposition of the fan 40 does not affect the external appearance of the indoor unit 1.

It will be appreciated that the location, shape, type of air flow driving device 20, location, shape, etc. of the air deflection assemblies 30 are all different when the forms of the air conditioning indoor units 1 are different. That is, the air outlet 11, the air flow driving device 20 and the air deflection assembly 30 may be appropriately selected according to the form of the indoor unit 1 of the air conditioner, which is not limited thereto.

For example, when the indoor unit 1 is a wall-mounted indoor unit, the air outlet 11 is generally formed at the bottom of the front side of the casing 10 and is a strip-shaped air outlet extending in a lateral direction. The airflow driving device 20 is preferably a cross-flow fan, but may be a centrifugal fan, an axial flow fan, an ion wind generating device, or other suitable devices capable of driving airflow to flow. The air deflection assembly 30 includes at least one transversely extending strip-shaped plate body.

For another example, when the indoor unit 1 is a cabinet air conditioner, the air outlet 11 is generally formed on the front side of the casing 10 and is a vertically extending strip-shaped air outlet. The airflow driving device 20 is preferably a cross-flow fan, but may be a centrifugal fan, an axial flow fan, an ion wind generating device, or other suitable devices capable of driving airflow to flow. The air deflection assemblies 30 are of a relatively wide variety and may include, for example, a plurality of vertically extending elongated plate members.

Further, the air conditioning indoor unit 1 may further include a heat exchanging device disposed in the casing 10 for exchanging heat with the air flow passing therethrough.

In some embodiments, each fan 40 is configured to start up and/or stop operation independently of the other fans 40.

That is, the rotation of each fan 40 is independent from the other fans 40, so that the softness of the air flow at the position of the fan can be flexibly adjusted according to the actual situation.

FIG. 4 is a schematic structural exploded view of a plurality of fans and their associated structures according to one embodiment of the utility model. In some embodiments, each fan 40 is coupled to a respective one of the drives 50 for controlled rotation under the drive of the drives 50. Wherein the respective drive means 50 are independent of each other such that each fan 40 is controlled to operate independently.

Each fan 40 is connected to a corresponding one of the driving devices 50, and is rotated by the driving device 50, thereby promoting the air flow to be diffused. Therefore, each fan 40 corresponds to a small air flow driving device with a power source, which can promote the air flow to flow faster, improve the air supply speed and the air supply amount of the air conditioner indoor unit 1, and prolong the air supply distance.

It will be appreciated that in other embodiments, each fan 40 may have no power source, and the fan 40 may be driven to rotate by the airflow in the casing 10, and the fan 40 may be used to blow off the airflow to achieve the purpose of softening the airflow.

In some embodiments, the air outlet 11 is formed at the bottom of the front side of the cabinet 10 and extends in the lateral direction of the cabinet 10. In this case, the air conditioning indoor unit 1 may be a wall-mounted air conditioning indoor unit.

Further, the fans 40 are distributed along the extending direction of the air outlet 11, so as to adjust the air supply softness of each position of the air outlet 11 along the length direction of the air outlet 11 by the fans 40, which is beneficial to the uniformity of the air outlet 11.

In some embodiments, the plurality of fans 40 are divided into two groups, one group being located on one side (e.g., left side) of the central position of the air outlet 11 in the lateral direction, and the other group being located on the other side (e.g., right side) of the central position of the air outlet 11 in the lateral direction.

Further, the plurality of fans 40 of the same group are configured to synchronously rotate at the same rotational speed in the same direction. Thus, the rotation speed and the rotation direction of the plurality of fans 40 can be controlled uniformly, and the control logic of the plurality of fans 40 can be simplified. And meanwhile, the uniform air outlet at the same side of the air outlet 11 is facilitated.

Further, the plurality of fans 40 in the same group are spaced apart from each other by the same distance, that is, the plurality of fans 40 in the same group are uniformly arranged in the lateral direction.

Further, the rotation directions of the plurality of fans 40 of different groups are opposite or the same.

Specifically, the rotational direction of the plurality of fans 40 of different groups may be selected according to a specific air supply mode. For example, when the air supply mode selected by the user is to supply air toward both sides of the cabinet 10, the rotation directions of the two sets of fans 40 may be opposite, one set supplying air toward the left side of the cabinet 10 and the other set supplying air toward the right side of the cabinet 10. For another example, when the air supply mode selected by the user is to direct air supply toward the right side of the cabinet 10, the rotation directions of the two sets of fans 40 are the same, and air is supplied toward the right side of the cabinet 10.

Further, the rotational speeds of the plurality of fans 40 of different groups are the same or different.

Specifically, the rotational speeds of the plurality of fans 40 of different groups may be selected according to the specific air supply mode. For example, when the air supply mode selected by the user is uniform air supply toward both sides of the cabinet 10, the rotation directions of the two sets of fans 40 may be opposite and the rotation speeds may be the same. For another example, when the air supply mode selected by the user is to accelerate air supply toward the right of the cabinet 10 and normal air supply toward the left of the cabinet 10, the rotation directions of the two sets of fans 40 are opposite, and the rotation speed of the set of fans 40 supplying air toward the left is lower than that of the set of fans 40 supplying air toward the right.

In some embodiments, the indoor unit 1 further includes a fixed support plate 60, and the fixed support plate 60 is disposed in the casing 10 and extends in a lateral direction of the casing 10.

Further, the fans 40 are located on the same side of the fixed support plate 60, and the driving devices 50 for driving the fans 40 to rotate are located on the other side of the fixed support plate 60, and the rotating shaft of the fan 40 passes through the fixed support plate 60 to be coaxially connected with a corresponding driving device 50, so as to be driven by the driving device 50 to rotate synchronously.

The plurality of fans 40 and the plurality of driving devices 50 are supported by one fixed support plate 60, which not only simplifies the structure of the indoor unit 1 of the air conditioner, but also facilitates the assembly of the fans 40 and the driving devices 50 and improves the assembly efficiency.

The utility model arranges the fans 40 and the driving devices 50 on two sides of the fixed support plate 60, which can support the fans 40 and the driving devices 50 by the same fixed support plate 60, and separate the fans 40 and the driving devices 50 on two sides, thereby avoiding mutual interference between the fans 40 and the driving devices 50.

In some embodiments, the stationary support plate 60 extends obliquely downward from back to front such that one side of the stationary support plate 60 faces forward upward and the other side faces rearward downward.

Further, a plurality of fans 40 are supported on the upper side of the fixed support plate 60 facing the air outlet 11, and a plurality of driving devices 50 are fixed on the lower side of the fixed support plate 60 facing away from the air outlet 11 by fasteners. Therefore, the fans 40 are located in the airflow flow path, and the postures of the fans 40 are exactly matched with the airflow flow direction of the location, so that when the fans 40 rotate, the airflow can be blown off in a proper direction, adverse phenomena such as countercurrent and turbulent flow in the air duct can not be generated, and the air outlet speed of the air outlet 11 can not be influenced.

Fig. 5 is a schematic structural exploded view of a stationary support plate and a portion of a cabinet according to one embodiment of the utility model. In some embodiments, the upper end of the stationary support plate 60 is provided with a tongue 61 and the lower end of the stationary support plate 60 is provided with a claw 62. The casing 10 is provided with a jack 121 corresponding to the insertion tongue 61, and the casing 10 is provided with a clamping groove 122 corresponding to the clamping jaw 62. The inserting tongue 61 is inserted into the inserting hole 121, and the claw 62 is clamped in the clamping groove 122, so that the fixing support plate 60 is firmly assembled to the casing 10.

Specifically, during assembly, the fan 40 and the driving device 50 may be first mounted to the fixed support plate 60 to form a pre-assembled part, and then the pre-assembled part is integrally assembled to the casing 10, so that the assembly of the fan 40 and the driving device 50 is not limited by a narrow space in the casing 10, and the operation difficulty is low and the assembly efficiency is high.

When the preassembly is assembled, the insert tongue 61 of the fixing support plate 60 can be inserted into the insertion hole 121 to realize the pre-positioning of the fixing support plate 60 and the casing 10, and then the lower end of the fixing support plate 60 is pressed downwards, so that the claw 62 of the fixing support plate 60 is clamped in the clamping groove 122, and the assembly between the preassembly and the casing 10 is easily realized.

Because the fixed support plate 60 is assembled only by inserting and clamping, no screw connection or other connection modes requiring a larger operation space exist, even if the space in the casing 10 is relatively narrow, the fixed support plate 60 is convenient to assemble, the operation difficulty is lower, and the assembly efficiency is higher.

Further, the casing 10 may specifically include a skeleton 12, a front panel 13, a cover 14, and two side end caps 15. The insertion holes 121 and the clamping grooves 122 are formed on the framework 12 with higher structural strength so as to support the fixed support plate 60 through the framework 12, and the structure is more stable.

In some embodiments, the air deflection assembly 30 may include one air deflection, or may include two air deflection or a greater number of air deflection.
