In order to simplify the present disclosure, components and arrangements of specific examples are described below. They are, of course, merely examples and are not intended to limit the utility model. Furthermore, the present utility model may repeat reference numerals and/or letters in the various examples.

Next, the air conditioner 100 of the present utility model is described with reference to the accompanying drawings.

As shown in fig. 1, an air conditioner 100 according to an embodiment of the present utility model includes: the air duct structure 2 and the diversion structure 4 are formed with a through-flow air duct 231 and an air outlet air duct 232 in the air duct structure 2, the through-flow air duct 231 is provided with a through-flow wind wheel 3, the through-flow wind wheel 3 provides flowing air flow, the inlet of the air outlet air duct 232 is communicated with the outlet of the through-flow air duct 231, the number of the air outlet air ducts 232 is two, and the air flow sent by the through-flow wind wheel 3 flows into the two air outlet air ducts 232 from the through-flow air duct 231 respectively and flows along the air outlet air duct 232 to finally flow out from the outlet of the air outlet air duct 232. The inlets of the two air outlet channels 232 are sequentially arranged in the width direction of the outlet of the through-flow air channel 231, the inlets of the two air outlet channels 232 split the air flow flowing out of the through-flow air channel 231, the outlet of the air outlet channel 232 conveys the air flow to the outside of the air conditioner 100, and the outlets of the two air outlet channels 232 extend towards the direction away from each other, so that the air supply range is increased, and the air flow coverage area of the air conditioner 100 is improved.

The flow dividing structure 4 is disposed in the air duct structure 2 and is located at the downstream of the through-flow wind wheel 3, and the flow dividing structure 4 includes two flow dividing plates 40, where the two flow dividing plates 40 are sequentially disposed in the width direction of the outlet of the through-flow air duct 231, that is, the flow dividing plates 40 are sequentially disposed along the interval direction of the two air outlet air ducts 232. The two flow dividing plates 40 extend from the through-flow air duct 231 to the two air outlet air ducts 232 respectively, so as to guide the air flow of the through-flow air duct 231 to flow to the two air outlet air ducts 232 respectively, and the flow dividing plates 40 are arranged to enable the air supply quantity of the two air outlet air ducts 232 to be relatively uniform, so that the air conditioner 100 can exchange heat with indoor air in different directions uniformly, and the heat exchange effect is improved.

Optionally, the two flow dividing plates 40 may extend in directions of different air outlet air channels 232, where the flow dividing plates 40 are in one-to-one correspondence with the air outlet air channels 232, and the two flow dividing plates 40 guide the air flow to the corresponding air outlet air channels 232, so that the air supply amounts of the two air outlet air channels 232 are relatively uniform; optionally, the two flow dividing plates 40 extend together towards the direction of one air outlet duct 232, but an included angle is formed between the extending directions of the two flow dividing plates 40, so as to guide the air flow to the two air outlet ducts 232 respectively, and make the air supply amounts of the two air outlet ducts 232 relatively uniform, which falls within the protection scope of the present utility model.

It should be noted that, since the air duct structure 2 defines the through-flow air duct 231 and the air outlet air duct 232 without the use of the splitter plate 40 to define the air duct, the splitter plate 40 only plays a role of splitting, so the splitter plate 40 does not need to be processed into a triangle, a wedge or the like to define the air duct, so that the splitter plate 40 can be in a plate-shaped structure, and the splitter plate 40 has light weight and low cost. Moreover, the through-flow air duct 231 and the air outlet air duct 232 are not defined by the splitter plate 40 and the air duct structure 2, so that the requirement on the relative position precision of the splitter plate 40 and the air duct structure 2 can be reduced, the assembly difficulty is reduced, and the production efficiency is improved.

According to the air conditioner 100 of the embodiment of the utility model, the air duct structure 2 comprises two air outlet air ducts 232, which is beneficial to enlarging the air supply range, and the air supply quantity of the two air outlet air ducts 232 can be relatively uniform by arranging the splitter plate 40, so that indoor air in different directions can be uniformly subjected to heat exchange, and the heat exchange effect is improved. And the flow dividing plate 40 has a simple structure, is convenient to arrange, can improve the occupation of the internal space of the air conditioner 100, reduces the assembly difficulty, improves the production efficiency and saves the manufacturing cost.

In some embodiments of the present utility model, each of the flow dividing plates 40 has an inflow end and an outflow end along the air flow direction, as shown in fig. 1, the direction indicated by the arrows is the air flow direction. The two flow dividing plates 40 extend away from each other from the inflow end to the outflow end such that the inflow end spacing L5 between the two flow dividing plates 40 is smaller than the outflow end spacing L9.

In some embodiments, the inflow end spacing L5 between the two flow splitter plates 40 is zero, i.e., the inflow ends of the two flow splitter plates 40 are connected to one another, while the outflow ends of the two flow splitter plates 40 are spaced apart from one another and extend in a direction away from one another. The air flows out from the outlets of the through-flow air ducts 231, and the air flows through the flow dividing plates 40 to be guided to the two air outlet air ducts 232 along the extending direction of the two flow dividing plates 40.

In other embodiments, as shown in FIG. 1, the inflow end spacing L5 between the two flow splitter plates 40 is greater than zero, i.e., the inflow ends of the two flow splitter plates 40 are spaced apart from each other and the outflow ends of the two flow splitter plates 40 are spaced apart from each other and extend in a direction away from each other. The air flows out from the outlets of the through-flow air ducts 231, and the air flows through the splitter plates 40 and is guided to the two air outlet air ducts 232 along the extending direction of the two splitter plates 40, and the air flows not only between the splitter plates 40 and the inner wall of the air duct structure 2, but also a small part of the air flows between the inflow ends of the two splitter plates 40 and along the channels formed by the two splitter plates 40, and finally is guided to the two air outlet air ducts 232. The inflow ends of the two flow dividing plates 40 are arranged between them, so that the flow dividing and the uniformity of air flow distribution are realized, and the flow communication of air flow is ensured. If there is no gap between the inflow ends of the two flow dividing plates 40, when the air flows through the flow dividing plates 40, the flow path of the air flow is reduced from the channel between the inner walls of the original air channel structure 2 to the channel between the inner walls of the air channel structure 2 and the flow dividing plates 40, so that the flow path of the air flow is reduced, and the flow property of the air flow is affected.

In some embodiments of the present utility model, as shown in fig. 2, the two air outlet channels 232 are a first air outlet channel 232a and a second air outlet channel 232b, the two flow dividing plates 40 are a first flow dividing plate 41 and a second flow dividing plate 42, respectively, the first flow dividing plate 41 extends from the inflow end to the outflow end towards the direction of the first air outlet channel 232a, and the second flow dividing plate 42 extends from the inflow end to the outflow end towards the direction of the second air outlet channel 232 b. The splitter plates 40 are in one-to-one correspondence with the air outlet air channels 232, the first splitter plate 41 guides the air flow to the first air outlet air channel 232a, and the second splitter plate 42 guides the air flow to the second air outlet air channel 232b, so that the air supply amounts of the first air outlet air channel 232a and the second air outlet air channel 232b are relatively uniform.

As shown in fig. 2, the extending direction of the outflow end of the first air outlet duct 232a is close to the air outlet direction of the through-flow duct 231 relative to the extending direction of the outflow end of the second air outlet duct 232b, so that the air flow flowing into the first air outlet duct 232a is more and the air flow flowing into the second air outlet duct 232b is less, and the inflow end of the second flow dividing plate 42 extends to the upstream of the inflow end of the first flow dividing plate 41, so that the air flow flowing into the second air outlet duct 232b can be increased, and the uniformity of the air flows of the first air outlet duct 232a and the second air outlet duct 232b can be improved.

Optionally, the extending directions of the outflow ends of the first air outlet duct 232a and the second air outlet duct 232b are consistent, and the included angle between the extending direction of the outflow end of the first air outlet duct 232a and the air outlet direction of the through-flow duct 231 is smaller than the included angle between the extending direction of the outflow end of the second air outlet duct 232b and the air outlet direction of the through-flow duct 231. Still alternatively, the extension direction of the outflow end of the first air outlet duct 232a and the air outlet direction of the through-flow duct 231 are the same, and the extension direction of the outflow end of the second air outlet duct 232b and the air outlet direction of the through-flow duct 231 are opposite.

In some embodiments of the present utility model, as shown in fig. 2, the air outlet direction of the through-flow air duct 231 is from back to front and from right to left (the inclination angle relative to the front-rear direction is a 1), then the air outlet end extending direction of the first air outlet air duct 232a is also from back to front and from right to left (the inclination angle relative to the front-rear direction is a2, a1 and a2 may be equal or not equal, as long as the inclination trend is right to left), and the air outlet end extending direction of the second air outlet air duct 232b is from back to front and from left to right. Therefore, the extending direction of the outflow end of the first air outlet duct 232a is close to the air outlet direction of the through-flow duct 231 with respect to the extending direction of the outflow end of the second air outlet duct 232 b.

In some embodiments of the present utility model, two flow dividing plates 40 are disposed at a distance from each other, with an inflow gap between the inflow ends of the two flow dividing plates 40, and an outflow gap between the outflow ends of the two flow dividing plates 40 and the inner wall of the corresponding air outlet duct 232.

An inflow gap is arranged between the inflow ends of the two flow dividing plates 40, so that the flow dividing and the uniformity of air flow distribution are realized, and meanwhile, the flow communication of air flow is ensured. The outflow ends of the two flow dividing plates 40 and the inner wall of the corresponding air outlet air duct 232 are provided with outflow gaps, and the outflow gaps are arranged in the same way, so that the flow dividing and the air flow distribution uniformity improvement are realized, the air flow circulation performance is ensured, the air flow circulation efficiency is improved, the ventilation quantity is ensured, and the air quantity attenuation loss is reduced. If there is no gap, an included angle is formed between the splitter plate 40 and the inner wall of the air outlet duct 232, and a vortex is formed in the included angle of the air flow channel, so that the air flow is affected, and the air quantity attenuation loss exists.

In some embodiments of the present utility model, as shown in fig. 2, the first and second flow dividing plates 41 and 42 are disposed at a distance, a minimum gap between the inflow ends of the first and second flow dividing plates 41 and 42 is an inflow gap L6, a minimum gap between the outflow end of the first flow dividing plate 41 extending toward the inner wall of the first air outlet duct 232a to the inner wall of the first air outlet duct 232a is a first outflow gap L8, and a minimum gap between the outflow end of the second flow dividing plate 42 extending toward the inner wall of the second air outlet duct 232b to the inner wall of the second air outlet duct 232b is a second outflow gap L7, wherein the inflow gap L6 is greater than or equal to the second outflow gap L7, and/or the first outflow gap L8 is greater than the second outflow gap L7.

It will be appreciated that, since the inflow end of the second flow dividing plate 42 is disposed to extend upstream of the inflow end of the first flow dividing plate 41, the amount of air flowing into the second air outlet duct 232b is increased, and thus the portion of air flowing from the inflow ends of the first flow dividing plate 41 and the second flow dividing plate 42 is guided to the first air outlet duct 232a, further improving the uniformity of the air flowing into the first air outlet duct 232a and the second air outlet duct 232 b.

Optionally, the inflow gap L6 is set to be greater than or equal to the second outflow gap L7, so that the air flow rate of the air flow between the first splitter plate 41 and the second splitter plate 42 to the second air outlet duct 232b is reduced, and the uniformity of the air flow in the first air outlet duct 232a and the second air outlet duct 232b is further improved.

Still alternatively, the first outflow gap L8 is set to be larger than the second outflow gap L7, so that the airflow quantity of the airflow between the first splitter plate 41 and the second splitter plate 42 flowing toward the first air outlet duct 232a is increased, and the uniformity of the airflows of the first air outlet duct 232a and the second air outlet duct 232b is further improved.

Still alternatively, the inflow gap L6 is set to be greater than or equal to the second outflow gap L7, and the first outflow gap L8 is set to be greater than the second outflow gap L7, so that the air flow uniformity of the first air outlet duct 232a and the second air outlet duct 232b is further improved by guiding the air between the first splitter plate 41 and the second splitter plate 42 to the first air outlet duct 232 a.

In some embodiments of the utility model, the inflow gap L6 has a value in the range of 3mm to 20mm and the second outflow gap L7 has a value in the range of 3mm to 15mm.

Alternatively, the inflow gap L6 may be 3mm, 5mm, 9mm, 10mm, 15mm, 16mm, 20mm, etc.

Alternatively, the second outflow gap L7 may be 3mm, 4mm, 5mm, 7mm, 9mm, 11mm, 15mm, etc.

It is understood that, when the inflow gap L6 is set to be equal to or greater than the second outflow gap L7, the second outflow gap L7 is always equal to or less than the inflow gap L6 on the basis of satisfying the above-described range of values.

In some embodiments of the present utility model, as shown in fig. 3, the air duct structure 2 includes two outer walls 21 and two inner walls 22, i.e., a first outer wall 211, a second outer wall 212, a first inner wall 221 and a second inner wall 222, and the air duct structure 2 is simple in structure and easy to manufacture. The first outer wall 211, the second outer wall 212, the first inner wall 221 and the second inner wall 222 extend in the axial direction of the cross-flow wind wheel 3, and a cross-flow air duct 231 is formed between the upstream section 211a of the first outer wall and the upstream section 212a of the second outer wall, and the cross-flow wind wheel 3 sends out air flow in the direction perpendicular to the axial direction of the cross-flow wind wheel 3. The first inner wall 221 and the second inner wall 222 are located between the downstream section 211b of the first outer wall and the downstream section 212b of the second outer wall, one end of the first inner wall 221 is connected with one end of the second inner wall 222, the other end of the first inner wall 221 extends towards the direction of the first outer wall 211 to form a first air outlet duct 232a between the downstream section 211b of the first outer wall and the first inner wall 221, and the other end of the second inner wall 222 extends towards the direction of the second outer wall 212 to form a second air outlet duct 232b between the downstream section 212b of the second outer wall and the second inner wall 222.

In some embodiments of the present utility model, as shown in FIG. 3, the first outer wall 211 is positioned to the left of the second outer wall 212, the upstream section 211a of the first outer wall includes a volute tongue 2111, the downstream section 211b of the first outer wall extends from right to left from back to front, and the downstream section 211b of the first outer wall extends from left to right from back to front. The first inner boundary wall 221 is located at the left side of the second inner boundary wall 222, the first inner boundary wall 221 extends obliquely to the left, and the downstream section 211b of the first outer boundary wall and the first air outlet duct 232a formed by the first inner boundary wall 221 extend obliquely to the left; the second inner boundary wall 222 extends obliquely rightward, and the downstream section 212b of the second outer boundary wall and the second air outlet duct 232b formed by the second inner boundary wall 222 extend obliquely rightward. The first flow dividing plate 41 extends leftward, and the second flow dividing plate 42 extends rightward.

As shown in fig. 3, since the volute tongue 2111 is located on the left side and the airflow in the second air outlet duct 232b on the right side is less, the inflow end of the second flow dividing plate 42 extends to the upstream of the inflow end of the first flow dividing plate 41, so that the airflow in the second air outlet duct 232b on the right side can be increased, and the uniformity of the airflows in the first air outlet duct 232a and the second air outlet duct 232b can be improved.

In some embodiments of the present utility model, the downstream section 211b of the first outer wall and the first inner wall 221 have wall parallel portions so that the first air outlet duct 232a has a first constant width section with a fixed flow width; and/or the downstream section 212b of the second outer wall and the second inner wall 222 have wall parallel portions so that the second air outlet duct 232b has a second equal width section with a fixed flow width. Wall parallelism is understood in a broad sense, and may be straight-to-straight or curved-to-curved.

The first air outlet air duct 232a has a first equal width section with a fixed over-current width and/or the second air outlet air duct 232b has a second equal width section with a fixed over-current width, and the whole flow area of the air flow is kept unchanged in the first equal width section or the second equal width section when the air flow flows, so that the flow property of the air flow can be ensured, the flow efficiency of the air flow is improved, and the condition that the flow property of the air flow is influenced by vortex is improved. And because the wind pressure of the cross flow wind wheel 3 is lower, the air supply distance is short, and the air resistance in the air outlet air duct 232 is reduced by arranging the first equal-width section and/or the second equal-width section, so that the air supply distance can be increased to a certain extent.
