The utility model provides an air deflector for a wall-mounted air conditioner indoor unit and a wall-mounted air conditioner indoor unit with the same. An indoor unit of a wall-mounted type air conditioner is an indoor part of a split wall-mounted type room air conditioner for conditioning indoor air, such as cooling/heating, dehumidifying, introducing fresh air, and the like.

FIG. 1 is a schematic cross-sectional view of a wind deflector according to an embodiment of the utility model; fig. 2 is a schematic structural view of a wall-mounted air conditioning indoor unit having the air guide plate of fig. 1.

As shown in fig. 1 and 2, the air deflector 50 according to the embodiment of the present invention is rotatably mounted at the outlet 12 of the wall-mounted indoor unit of an air conditioner about a rotation axis parallel to the length direction thereof, and is used for guiding the air outlet direction of the outlet 12. The air deflector 50 is a long strip with the length direction parallel to the length direction of the air outlet, and the rotation axis of the air deflector 50 is parallel to the length direction.

The air guiding plate 50 includes a plurality of grills 51, 52, 53, the plurality of grills 51, 52, 53 extend along the length direction of the air guiding plate 50, and are sequentially arranged at intervals along the width direction of the air guiding plate 50 to form a plurality of strip-shaped air outlet gaps 510, 520, so that when the air guiding plate 50 guides the air outlet direction of the air outlet 12, part of air is allowed to flow through each air outlet gap 510, 520 from the side of the air guiding surface 501 of the air guiding plate 50 to the side of the leeward surface 502 of the air guiding plate 50. The air outlet directions of the air outlet gaps 510 and 520 are not completely the same. In other words, the air outlet gaps 510 and 520 do not discharge air in the same direction.

In an alternative arrangement, the air deflector 50 may comprise only one set of grate bars, the longitudinal ends of each grate bar forming the longitudinal ends of the air deflector 50. In other embodiments, the wind deflector 50 may be formed by a plurality of grid bars arranged along the length of the wind deflector 50. For example, if two sets of grill bars are included, the sum of the length of one grill bar in the first set and the length of one grill bar in the second set is equal to or approximately equal to the length of the air deflection assembly.

In the embodiment of the present invention, the air deflector 50 includes a plurality of grid bars 51, 52, 53 to form a plurality of strip-shaped air outlet gaps 510, 520. When the air deflector 50 guides air, the main body of the outlet air flow at the air outlet 12 is guided by the air guiding surface 501 of the air deflector 50 and blown to the direction pointed by the air deflector 50, so as to rapidly cool/heat the indoor environment. A small part of the air flows through the air outlet gaps 510 and 520 from the side of the air guiding surface 501 of the air guiding plate 50 to the side of the leeward surface 502 of the air guiding plate 50, which is hereinafter referred to as a through-flow air flow. The air flow passing through the air outlet gaps 510 and 520 and the air flow guided by the air guide plate 50 are blown to the indoor environment. Two kinds of air current are blown to indoor environment jointly for the holistic air supply scope of wall-hanging air conditioning indoor set is bigger, and the air supply is more even. The air flow passing through the air outlet gaps 510 and 520 is finer, is similar to natural wind, and is more comfortable, so that the human body feels more comfortable. Therefore, the wall-mounted air conditioner indoor unit has both cooling/heating rapidity and comfort.

Moreover, since the air flow can penetrate through the air deflector 50, the leeward surface 502 of the air deflector 50 does not generate condensation.

In the prior art in some air conditioning fields, a plurality of densely arranged air dissipation holes, or micropores, are formed in an air deflector to achieve a micropore air supply effect. The embodiment of the present invention is very different from the microporous solution. In the embodiment of the present invention, the air outlet gaps 510 and 520 are formed by the adjacent grille strips 51, 52 and 53, which is different from the conventional scheme of forming a plurality of densely arranged air outlet holes. Compared with the air outlet scheme, the utility model utilizes the air outlet gaps 510 and 520 formed by the grid bars 51, 52 and 53, so that the air outlet directions of the air outlet gaps 510 and 520 can be more conveniently designed, the grid bars 51, 52 and 53 are longer, linear through-flow air flow is formed, and the guide force of the grid bars 51, 52 and 53 to the linear air flow is larger. And simple air dispersing holes can only perform micro-hole air outlet, and the guiding force to the air outlet direction is too small. In addition, under the condition that the total air passing and exiting areas are equal, the strength of the air deflector is easily damaged due to the arrangement of the plurality of densely arranged air dispersing holes, and the integral strength of the air deflector 50 is higher by utilizing the grating strips 51, 52 and 53, so that the reliability can be ensured.

In some embodiments, as shown in fig. 1, the air outlet directions of the air outlet gaps 510 and 520 are far away from each other. In other words, the outlet air flows of any two adjacent outlet air gaps 510 and 520 are far away from each other. This allows the entire air flow to exit the air deflector 50 in a diffuse manner, which provides increased dispersion and comfort.

In some embodiments, as shown in fig. 1, each of the outlet gaps 510 and 520 may have a gradually expanding shape with a gradually increasing cross section along the outlet direction. The air outlet gaps 510 and 520 in the divergent shape enable the air outlet flow to be more dispersed in the flowing process, and the comfort degree is higher. Moreover, the resistance to the air flow is also made smaller.

In some embodiments, as shown in fig. 1, the side of each grille strip 51, 52, 53 opposite to the adjacent grille strip forms a side wall 503 of the air outlet gap 510, 520, and the side wall 503 of the air outlet gap is a plane. This makes the air outlet of the air outlet gaps 510 and 520 smoother, and the flow resistance is smaller.

In some embodiments, as shown in fig. 1, the air guiding plate 50 is entirely symmetrical with respect to a symmetry plane N parallel to the length direction thereof, and the air outlet directions of the air outlet gaps 510 and 520 located at two sides of the symmetry plane N gradually deviate from the symmetry plane N. Thus, the air guiding plate 50 forms two air outlet sections by taking the symmetry plane N as a boundary, so as to substantially exhaust air towards two regions, thereby enlarging the air supply range. The widths of the air outlet gaps on the two sides of the symmetry plane N can be different, so that air flow speed beams with different sizes can be obtained. Specifically, the inlet width a of one air outlet gap may be greater than the inlet width b of the other air outlet gap.

Further, of the grid bars 51, 52, 53, the angle between the grid bars 51, 52, 53 farther from the symmetry plane and the symmetry plane N is larger, so that the air guiding plate 50 is curved as a whole, and the concave surface of the air guiding plate 50 forms an air guiding surface 501 and the convex surface forms a leeward surface 502. For example, the entire air guide plate 50 may have an arc shape, and the inner surfaces of the grating strips 51, 52, and 53 are located on the same arc surface, thereby forming the air guide surface 501 of the air guide plate 50. The number of grid bars 51, 52, 53 may be an odd number, for example 5 as shown in fig. 1. The central grid 53 is symmetrical with respect to the plane of symmetry, and the two grid strips 51, 52 are symmetrical with respect to the plane of symmetry N.

Fig. 2 is a schematic structural view of a wall-mounted air conditioner indoor unit having the air guide plate of fig. 1; fig. 3 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 with a louver in a forward blowing state; fig. 4 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 in a state where the air deflector is blowing down; fig. 5 is a schematic view of the wall-mounted air conditioning indoor unit of fig. 2 when the air deflector is in a maximum outlet state.

As shown in fig. 2 to 5, a wall-mounted air conditioning indoor unit according to an embodiment of the present invention may generally include a casing 10 and at least one air deflector. The casing 10 is provided with an air outlet 12, and the air deflector is the air deflector 50 of any of the above embodiments, and is rotatably installed at the air outlet 12 around a rotation axis parallel to the length direction thereof.

The housing 10 may be an elongated shape having a length direction (a direction perpendicular to the paper surface of fig. 2) horizontally arranged. The casing 10 defines an accommodation space for accommodating components of a wall-mounted air conditioning indoor unit. The housing 10 is provided with an air outlet 12 for discharging air flow therein, wherein the discharged air flow is acted by the fan 40 in the housing 10 to accelerate the air flow flowing through the air outlet 12 for adjusting the indoor environment, such as cold air in a cooling mode, hot air in a heating mode, fresh air flow in a fresh air mode, and the like. The outlet 12 and the air deflector 50 may be long strips with the length direction parallel to the length direction of the casing 10.

The wall-mounted air conditioner indoor unit may be an indoor part of a split wall-mounted type room air conditioner that performs cooling/heating using a vapor compression refrigeration cycle system. As shown in fig. 2, the inside of the case 10 is provided with a heat exchanger 30 and a fan 40. The heat exchanger 30 and the throttling device are connected with a compressor, a condenser and other refrigeration elements arranged in the air conditioning chamber outer shell 10 through pipelines to form a vapor compression refrigeration cycle system. Under the action of the fan 40, the indoor air enters the inside of the casing 10 through the air inlet 11 at the top of the casing 10, and after the forced convection heat exchange with the heat exchanger 30 is completed, heat exchange air is formed and enters the air duct 20. The fan 40 is preferably a cross-flow fan having an axis parallel to the length of the housing 10, and is disposed at the inlet of the air duct 20. The heat exchanger 30 may be a three-stage heat exchanger.

The wall-mounted type air conditioning indoor unit further includes a front air duct wall 200 and a rear air duct wall 100. The front duct wall 200 and the rear duct wall 100 are spaced forward and rearward to define the aforementioned duct 20. The outlet ends of the front duct wall 200 and the rear duct wall 100 are respectively connected to two ends of the air outlet 12, so that the air flow supplied from the air duct 20 flows to the air outlet 12. The front portion of the front air duct wall 200 may be provided with an inward recessed section 210 to give way to the air guide plate 50, thereby preventing the air guide plate 50 from interfering with the front air duct wall 200 when rotating. Due to the concave section 210 of the front duct wall 200, the air deflector 50 can be designed to be wider, so that it can guide the airflow more strongly. Specifically, the concave section 210 may be a circular arc whose axis coincides with the rotation axis of the wind deflector 50

In some embodiments, as shown in fig. 2 to 5, the air outlet 12 is opened toward the front and downward, so that the air outlet 12 can supply air both toward the front and downward. The air guide plate 50 has a plurality of states so that the wall-mounted air conditioner indoor unit has a plurality of air supply modes.

As shown in fig. 2, the air guide plate 50 has a closed state in which the outlet 12 is closed and the air guide surface 501 faces the inside of the outlet 12. When the wall-mounted air conditioning indoor unit is in the shutdown state, the air guide plate 50 is in the closed state to close the air outlet 12. When the wall-mounted air conditioner indoor unit operates, the air deflector 50 can also move to a closed state, so that all the air outlet flow is blown out through the air outlet gaps 510 and 520, and a full breeze air supply effect is achieved.

As shown in fig. 3, the air guide plate 50 has a forward blowing state in which the air guide surface 501 faces upward to guide the air flow to be blown forward or upward. When the wall-mounted air conditioner indoor unit is used for refrigerating, the air supply mode can be adopted, so that cold air is upwards guided by the air guide surface 501, the air supply distance of the cold air is longer, and the cold air is downwards scattered after reaching the highest point, and a bathing type refrigerating effect is formed. At the same time, part of the outlet air flow is blown out to the front lower side through the outlet air gaps 510 and 520.

As shown in fig. 4, the air guide plate 50 has a downward blowing state in which the air guide surface 501 faces rearward and guides the air flow downward. The wall-mounted air conditioner indoor unit can adopt the air supply mode during heating, and the air guide surface 501 guides air flow to blow out downwards, so that the air outlet direction of the air flow is closer to or reaches the vertical downward direction, the air flow reaches the ground more, and a carpet type sinking air supply effect is realized.

As shown in fig. 5, the air guiding plate 50 further has a maximum air outlet state that the air guiding surface 501 faces forward and upward to guide the airflow to blow forward and downward. At this time, the air deflector 50 has the minimum guiding function to the air flow, which is beneficial to the air flow to be blown out more smoothly, so that the air quantity is maximized, and the refrigerating/heating speed is fastest.

It should be noted that the above examples are only for describing the operation principle of the air deflector of the present embodiment more clearly, and are not used to limit the operation mode (heating or cooling) of the wall-mounted air conditioner indoor unit when the air deflector is at any position. The user can adjust the working position of the air guiding plate at will according to the actual situation, for example, adjust the air guiding plate to the forward blowing state in the heating mode, adjust the air guiding plate 50 to the downward blowing state in the cooling mode, and so on, which will not be described herein.

Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the utility model may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the utility model. Accordingly, the scope of the utility model should be understood and interpreted to cover all such other variations or modifications.
