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.

In one aspect, the present utility model provides a guide bar for an indoor unit of an air conditioner. The indoor unit of the air conditioner is an indoor part of a split air conditioner or an indoor end machine type of a central air conditioner. Air conditioners are used to condition indoor air, including adjusting the temperature, humidity, air quality of the air, humidifying the indoor air, dehumidifying, introducing fresh air, and the like. The air conditioner may be constituted by an evaporator, a condenser, a compressor, a throttle device and other necessary elements to form a vapor compression refrigeration cycle system to output cool/hot air through a fan to achieve cooling and heating of an indoor environment. The air conditioning indoor unit may specifically be a wall-mounted air conditioning indoor unit, as shown in fig. 1 and 2, or may be a vertical air conditioning indoor unit.

Fig. 1 is a schematic view of an air conditioner indoor unit according to an embodiment of the present utility model; fig. 2 is an enlarged view of a cross-sectional view (not a cross-sectional view) of the air conditioning indoor unit shown in fig. 1. The direction of flow of the air stream is indicated by arrows in fig. 2.

The guide rod 30 of the embodiment of the utility model is used for being installed at the air supply port 11 of the casing 10 of the indoor unit of the air conditioner, and is used for allowing the air flow in the casing 10 to bypass the guide rod 30 and then be blown out of the casing 10.

In some embodiments, the deflector rod 30 functions to achieve a collective air delivery effect. As shown in fig. 1 and 2, an air duct 15 connected to the air supply port 11 is formed inside the casing 10, and the distance between two opposite air guiding walls 151 (in particular, ba sections thereof) and 152 (in particular, ed sections thereof) of the air duct 15 adjacent to the air supply port 11 is gradually reduced along the air flow direction to form a tapered section. In other words, the flow cross section of the duct 15 becomes gradually smaller in the air flow direction in the vicinity of the air supply port 11. The guide rod 30 is disposed in the air duct 15, and defines air outlet gaps 154 and 155 with the two air guiding walls 151 and 152, respectively, and is used for guiding the air flow blown to the air supply port 11 to the two air guiding walls 151 and 152, so that the air flow gradually flows out of the air supply port 11 toward the air flow center in a converging manner under the guidance of the air duct converging section.

Due to the addition of the guide rods 30, the flow cross section of the air outlet gaps 154 and 155 is necessarily smaller than that of the original air duct 15, so that the air flow speed is faster. Under the guidance of the tapering section of the air duct 15, the high-speed air flow gradually converges towards the air flow center direction in the outward flowing process, so as to form a converging effect, so that the wind power is very strong, the air supply distance is longer, the requirements of the wall-mounted air conditioner indoor unit on long-distance air supply and strong air supply are met, the air supply range is larger, the refrigerating/heating speed of the indoor space is more uniform, and the human body feel is more comfortable.

In other embodiments, the deflector rod 30 functions to achieve a split air supply effect. Specifically, the air guiding rod 30 is disposed at the outer side of the air supplying opening 11 (i.e. the air guiding rod 30 is adapted to move forward on the basis of fig. 2), so that after the air flow flowing out of the air supplying opening 11 is directed towards the air guiding rod 30, the air flows out of two sides of the air guiding rod 30 in the width direction respectively, so as to form two air supplying air flows, and a diversion effect is formed, so that the air flows are more dispersed and comfortable.

The number of the plug boards 202 at both ends of the second cover board 200 in the length direction is different, so that the second cover board 200 can be installed only in a unique posture, which can play a role in effective foolproof and prevent an operator from misplacing the direction in the assembly process. For example, as shown in fig. 5, one plug board 202 may be provided at one end in the length direction of the second cover plate 200, and two plug boards 202 may be provided at the other end. Accordingly, the number of the clip grooves 160 of one end plate 102 is made one, and the number of the clip grooves 160 of the other end plate 102 is made two.

Further, three tabs 202 may be positioned at three vertices of an isosceles triangle, thus forming a triangle-shaped stabilizing structure that further stabilizes the positioning of the first and second cover panels 100, 200.

In some embodiments, referring to fig. 5, the plurality of first clamping portions 110 may be spaced apart at two edges of the first cover plate 100 in the width direction, i.e. two long edges f-edge and k-edge. The plurality of second catching portions 210 are spaced apart at both edges of the second cover plate 200 in the width direction, i.e., two long sides m and n. By such design, the connection between the long sides of the first cover plate 100 and the second cover plate 200 can be more tightly focused, so that serious flashing seams are avoided to influence the appearance.
