Next, the air conditioner 1000 of the present utility model is described with reference to the accompanying drawings.

As shown in fig. 1 to 3, an air conditioner 1000 according to an embodiment of the present utility model includes: the shell member 100 and the air outlet member 200, the air outlet member 200 is arranged in the shell member 100, and the shell member 100 plays a supporting and protecting role. The casing component 100 is provided with a plurality of first air outlets 11 and second air outlets 12, the first air outlets 11 are arranged at intervals along the horizontal direction, the length direction of the first air outlets 11 extends along the vertical direction, and the second air outlets 12 are at least one and are higher than or lower than the first air outlets 11.

The air conditioner 1000 is provided with a plurality of first air outlets 11 which are spaced in the horizontal direction, so that the air supply range of the air conditioner 1000 in the horizontal direction is enlarged; and through setting up the first air outlet 11 and the second air outlet 12 of co-altitude, can increase the air supply scope of air conditioner 1000 in upper and lower orientation, air conditioner 1000 has stronger air supply ability and farther air supply distance, promotes the air-out coverage area of air conditioner 1000.

As shown in fig. 2, the air outlet component 200 includes an air duct assembly 2, a cross-flow wind wheel 3 and a flow dividing structure 4, the air duct assembly 2 is used for defining a flow direction of air flow, and as shown in fig. 3, the air duct assembly 2 defines a first air duct 23 and a second air duct 24; the cross flow wind wheel 3 provides flowing airflow, the axial direction of the cross flow wind wheel 3 is vertical and is arranged in the first air duct 23, the first air duct 23 comprises a plurality of air outlet air ducts 232, the plurality of air outlet air ducts 232 are correspondingly communicated with the plurality of first air outlets 11 respectively, and the second air duct 24 is communicated between the first air duct 23 and the second air outlet 12. The air flow sent by the cross flow wind wheel 3 flows along the plurality of air outlet air channels 232, part of the air flow flows out from the first air outlet 11, and the other part of the air flow enters the second air channel 24 and flows out from the second air outlet 12. The flow dividing structure 4 is disposed in the first air duct 23 and downstream of the cross-flow wind wheel 3, and is used for guiding airflow to at least one air outlet air duct 232. The split structure 4 is used for enabling the air supply quantity of at least two air outlet air channels 232 to be relatively uniform, so that the air output quantity of the corresponding two first air outlets 11 tends to be uniform. The air output of at least two first air outlets 11 of the air conditioner 1000 is uniform, and when the air conditioner 1000 exchanges heat with the air at the corresponding first air outlets 11, the heat exchange effect is uniform, and the uniformity of indoor temperature is improved.

It should be noted that, the split structure 4 is disposed in the first air duct 23 and is used for guiding the airflow to flow to the air outlet duct 232, so that the split structure 4 does not affect the air supply of the second air duct 24, and the second air outlet 12 keeps normal air supply.

It should be further noted that, since the air duct assembly 2 forms the first air duct 23 and the second air duct 24 for air flow, the air duct is not limited by the split structure 4, and the split structure 4 only plays a role in splitting, so that the split structure 4 has a simple structure, the manufacturing difficulty can be reduced, and the manufacturing cost can be reduced. The requirements on the relative position precision of the split structure 4 and the air duct assembly 2 can be reduced, the assembly difficulty is reduced, and the production efficiency is improved.

According to the air conditioner 1000 of the embodiment of the utility model, a plurality of first air outlets 11 spaced in the horizontal direction and second air outlets 12 spaced in the height direction are provided, the air conditioner 1000 has stronger air supply capability and longer air supply distance, and the air outlet coverage area of the air conditioner 1000 is improved. The air supply quantity of at least two first air outlets 11 can be relatively uniform through the arrangement of the flow distribution structure 4, so that indoor air in different directions can be subjected to uniform heat exchange, and the heat exchange effect is improved. And the structure of the shunt structure 4 is simple, the arrangement is convenient, the assembly difficulty can be reduced, the production efficiency is improved, and the manufacturing cost is saved.

In some embodiments of the present utility model, as shown in fig. 4, the first air duct 23 includes a through-flow air duct 231 extending vertically along a length direction, the through-flow wind wheel 3 is disposed at an inlet of the through-flow air duct 231, an outlet of the through-flow air duct 231 is respectively communicated with inlets of the plurality of air outlet air ducts 232, and air flows from the through-flow wind wheel 3 into the plurality of air outlet air ducts 232 respectively from the through-flow air duct 231 and flows from the plurality of first air outlets 11 along the air outlet air duct 232. The length direction of each air outlet duct 232 also extends vertically, and the inlets of the plurality of air outlet ducts 232 are sequentially disposed along the width direction of the outlets of the through-flow duct 231. For example, in other embodiments of the present utility model, the inlets of the plurality of air outlet channels 232 may be sequentially disposed along the length direction of the outlets of the through-flow channels 231.

The flow dividing structure 4 includes at least one flow dividing plate 40, and the flow dividing plate 40 may be one or multiple, so as to realize relatively uniform air supply of at least two air outlet channels 232. When the inlets of the plurality of air outlet channels 232 are sequentially arranged along the width direction of the outlets of the through-flow channels 231, the length direction of the flow dividing plate 40 extends vertically, and the width direction of the flow dividing plate 40 extends from the through-flow channels 231 to the air outlet channels 232 for guiding the airflow to flow to the corresponding air outlet channels 232. The structure of the flow dividing plate 40 is simple, and the flow dividing structure 4 only plays a role in flow dividing, so that the flow dividing structure 4 does not need to be processed into a triangular structure, a wedge shape or the like, and the air channel is required to be limited, the flow dividing structure 4 can be the flow dividing plate 40 with a plate-shaped structure, and the flow dividing plate 40 is light in weight and low in cost.

In some embodiments of the present utility model, the diverter plate 40 is fixedly positioned such that the diversion direction of the diverter plate 40 is fixed. The diverter plate 40 is fixed rather than movable (e.g., rotatable), which reduces the difficulty of setting and controlling the diverter plate 40, reduces the cost, and ensures the diverting reliability of the diverter plate 40.

In the first embodiment of the present utility model, as shown in fig. 5, the number of the flow dividing plates 40 is one, and the width direction of the flow dividing plates 40 extends from the through-flow duct 231 toward one of the plurality of air outlet ducts 232, which has a relatively small air intake. The air intake amount refers to the air intake amount of the air outlet duct 232 before the flow dividing structure 4 is not provided.

By arranging the flow dividing plate 40 to extend to the air outlet air duct 232 with relatively small air inlet amount, the air flow amount flowing to the air outlet air duct 232 is increased, so that the air inlet amounts of at least two air outlet air ducts 232 are relatively uniform, and the air outlet amounts of the corresponding two first air outlets 11 tend to be uniform.

In the first embodiment of the present utility model, as shown in fig. 5, the number of the air outlet channels 232 is two, and the number of the air outlet channels 232 is two, namely the first air outlet channel 232a and the second air outlet channel 232b, and the extending direction of the outflow end of the first air outlet channel 232a is close to the air outlet direction of the through-flow channel 231 relative to the extending direction of the outflow end of the second air outlet channel 232b, so that the air flow flowing into the first air outlet channel 232a is more and the air flow flowing into the second air outlet channel 232b is less. The inlet end of the splitter plate 40 is located at the outlet center of the through-flow air duct 231 and is biased to one side of the first air outlet air duct 232a, where the bias means that the inlet end of the splitter plate 40 is close to one side of the first air outlet air duct 232a, for example, a distance L3 between the inlet end of the splitter plate 40 and an inner wall surface close to the first air outlet air duct 232a shown in fig. 5 is smaller than a distance L4 between the inlet end of the splitter plate 40 and an inner wall surface close to the second air outlet air duct 232b, so that the air flow is separated by the second air outlet air duct 232b by more air flow at the inlet end of the splitter plate 40; the outflow end of the flow dividing plate 40 extends toward the second air outlet duct 232b, and increases the airflow flowing toward the second air outlet duct 232b, thereby improving the uniformity of the airflows of the first air outlet duct 232a and the second air outlet duct 232 b.

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. 5, 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 the first embodiment of the present utility model, the inflow end of the splitter plate 40 is spaced from the inner wall surface of the through-flow air duct 231, so as to ensure the air supply path of the air flow to the air outlet air duct 232 to be smooth, and improve the air flow resistance of the air flow from the through-flow air duct 231 to the air outlet air duct 232, and improve the air flow. And, the interval between the inflow end of the flow dividing plate 40 and the inner wall surface of the through-flow air duct 231 is not less than 1/3 of the flow passing width of the through-flow air duct 231 where the inflow end of the flow dividing plate 40 is arranged, so that the flow-through property of the air flow is further improved. The over-current width refers to the dimension perpendicular to the airflow direction on the cross section of the air duct assembly 2 (i.e. the cross section perpendicular to the axial direction of the through-flow wind wheel 3), and the through-current width can be used for obtaining the airflow passing area in a visual way.

In some embodiments, the inflow end of the diverter plate 40 is offset to one side of the first air outlet duct 232a, and the distance from the inflow end of the diverter plate 40 to the inner wall of the through-flow duct 231 offset to the direction of the first air outlet duct 232a is 1/3 to 1/2 of the flow width of the through-flow duct 231 at the inflow end of the diverter plate 40. The inflow end of the splitter plate 40 is disposed closer to the first air outlet duct 232a, so that the airflow split by the second air outlet duct 232b can be further increased, and the uniformity of the airflows of the two air outlet ducts 232 can be improved.

In the first embodiment of the present utility model, as shown in fig. 5, an overflow gap G1 is provided between the outflow end of the flow dividing plate 40 and the inner wall surface of the second air outlet duct 232b. Through setting up the overflow clearance G1, when realizing reposition of redundant personnel, improving air current distribution homogeneity, guarantee the circulation of air current, improve air current circulation efficiency, guarantee the ventilation volume, reduce the amount of wind decay loss. If there is no gap, an angle is formed between the flow dividing plate 40 and the inner wall surface, and a vortex is formed in the angle of the airflow channel, which affects the airflow circulation and causes a loss of air volume attenuation.

In some embodiments of the first part of the present utility model, as shown in fig. 5, the air duct assembly 2 includes two outer walls 21 and two inner walls 22, namely, 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 assembly 2 has a simple structure and is 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 boundary wall 221 and the second inner boundary wall 222 are both located between the downstream section 211b of the first outer boundary wall and the downstream section 212b of the second outer boundary wall, one end of the first inner boundary wall 221 is connected with one end of the second inner boundary wall 222, and the other end of the first inner boundary wall 221 extends towards the direction of the first outer boundary wall 211 so as to form a first air outlet duct 232a between the downstream section 211b of the first outer boundary wall and the first inner boundary wall 221; the other end of the second inner peripheral wall 222 extends in a direction toward the second outer peripheral wall 212 to form a second outlet air duct 232b between the downstream section 212b of the second outer peripheral wall and the second inner peripheral wall 222.

As shown in fig. 5, the first outer wall 211 is located on the left side of the second outer wall 212, the upstream section 211a of the first outer wall includes a tongue portion 2111, the downstream section 211b of the first outer wall extends from right to left from rear to front, and the downstream section 211b of the first outer wall extends from left to right from rear 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.

Because the volute tongue 2111 is located on the left side and the second air outlet duct 232b on the right side has less airflow, the minimum distance L3 between the inflow end of the flow dividing plate 40 and the first outer wall 211 is smaller than the minimum distance L4 between the inflow end of the flow dividing plate 40 and the second outer wall 212, and the outflow end of the flow dividing plate 40 extends toward the second air outlet duct 232 b. By setting L3 < L4, the air flow separated by the right air outlet air duct 232 can be further increased, and the uniformity of the air flow of the left air outlet air duct 232 and the right air outlet air duct 232 is improved.

In some embodiments of the first portion of the present utility model, as shown in fig. 5, the downstream section 212b of the second outer wall includes a first extension 2121, the first extension 2121 extends in a direction away from the first outer wall 211 with respect to the upstream section 212a of the second outer wall, and the first extension 2121 extends in a direction toward the right. The second inner boundary wall 222 and the first extension 2121 together form a second air outlet duct 232b, and the second inner boundary wall 222 includes a second extension 2221 and a third extension 2222 sequentially arranged along an airflow direction, where the airflow direction indicates an airflow direction in the air outlet duct 232, and the second extension 2221 is disposed farther from the first air outlet 11 than the third extension 2222, as shown in an arrow direction in the figure.

The outflow end of the splitter plate 40 extends toward the direction of the second air duct 232b, specifically, the outflow end of the splitter plate 40 extends toward the direction of the second inner boundary wall 222, and an over-flow gap G1 is required between the splitter plate 40 and the second inner boundary wall 222, so that the second extension portion 2221 deflects and extends toward a direction away from the first extension portion 2121 against the air flow direction relative to the third extension portion 2222, so as to avoid the splitter plate 40, avoid the interference between the splitter plate 40 and the second inner boundary wall 222, so that the splitter plate 40 can extend a longer distance, and the drainage effect of the splitter plate 40 is improved. In addition, by providing the second extension portion 2221 for deflecting and extending to avoid the flow dividing plate 40, the flow passing gap G1 between the flow dividing plate 40 and the second inner boundary wall 222 can be ensured, the flow-through property of the air flow can be ensured, the air flow efficiency can be improved, the ventilation quantity can be ensured, and the air quantity attenuation loss can be reduced.

In some embodiments of the utility model, as shown in fig. 5 and 8, the downstream section 211b of the first outer wall includes a first curve section 2112 and a first straight section 2113 disposed in sequence along the airflow direction, the first curve section 2112 smoothly transitioning the tongue portion 2111 and the first straight section 2113. For example, the first curve segment 2112 is tangent to the tongue portion 2111 and the first straight segment 2113, respectively, such that the first curve segment 2112 and the tongue portion 2111 smoothly transition, and the first curve segment 2112 and the tongue portion 2111 smoothly transition. The first inner boundary wall 221 includes a second curved section 2211 and a second straight section 2212 sequentially arranged along the airflow direction, and a part of the first curved section 2112 and the second curved section 2211 together form a part of the first air outlet duct 232a, and the first straight section 2113 and the second straight section 2212 together form another part of the first air outlet duct 232 a.

As shown in fig. 8, the first air outlet duct 232a has a constant width section with a fixed flow width, the included angle A1 between the first straight line section 2211 and the second straight line section 2212 is 0 degrees, the first straight line section 2113 and the second straight line section 2212 are parallel to form a constant width section with a fixed flow width, when the air flows between the first straight line section 2113 and the second straight line section 2212, the flow property of the air flow can be ensured, the flow efficiency of the air flow is improved, and the occurrence of the condition that the flow property of the air flow is affected by the eddy is improved.

In some embodiments, the second curve segment 2211 is also disposed according to the direction of extension of the first curve segment 2112, and the overcurrent width between the second curve segment 2211 and the first curve segment 2112 is also fixed. And the overcurrent width between the first curve segment 2112 and the second curve segment 2211 is equal to the overcurrent width between the first straight line segment 2113 and the second straight line segment 2212. The downstream section 211b of the first outer wall and the first inner wall 221 form an air outlet duct 232, the whole flow area is kept unchanged, the air flow circulation is ensured, the air flow circulation efficiency is further improved, and the condition that vortex influences the air flow circulation is improved.

In the second embodiment of the present utility model, the number of the flow dividing plates 40 is plural, and the number of the flow dividing plates 40 may be two or more. The plurality of flow dividing plates 40 are disposed in sequence along the width direction of the outlet of the through-flow duct 231, and extend from the through-flow duct 231 toward each of the air outlet ducts 232 at least one flow dividing plate 40, respectively. Each air outlet duct 232 has a corresponding flow dividing plate 40 for dividing the air so that the air supply amount in the air outlet ducts 232 is uniform.

In the second embodiment of the present utility model, as shown in fig. 6, two air outlet channels 232 are provided, the two air outlet channels 232 are a first air outlet channel 232a and a second air outlet channel 232b, the extending direction of the outflow end of the first air outlet channel 232a is close to the air outlet direction of the through-flow air channel 231 relative to the extending direction of the outflow end of the 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, the first flow dividing plate 41 extends towards the direction of the first air outlet channel 232a, and the second flow dividing plate 42 extends 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.

Since the extension 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 extension direction of the outflow end of the second air outlet duct 232b, 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. In the second embodiment of the present utility model, the inflow end of the second splitter plate 42 extends to the upstream of the inflow end of the first splitter plate 41, so that the airflow flowing to the second air outlet duct 232b 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 the second embodiment of the present utility model, as shown in fig. 6, the first splitter plate 41 and the second splitter plate 42 are disposed at a distance, the minimum gap between the inflow ends of the first splitter plate 41 and the second splitter plate 42 is the inflow gap L6, the minimum gap between the outflow end of the first splitter plate 41 extending toward the inner wall of the first air outlet duct 232a and the inner wall of the first air outlet duct 232a is the first outflow gap L8, and the minimum gap between the outflow end of the second splitter plate 42 extending toward the inner wall of the second air outlet duct 232b and the inner wall of the second air outlet duct 232b is the second outflow gap L7. Wherein the inflow gap L6 is larger than or equal to the second outflow gap L7, and/or the first outflow gap L8 is larger than the second outflow gap L7.

The inflow ends of the first and second flow dividing plates 41 and 42 have an inflow gap L6 therebetween, and the air flows not only between the flow dividing plates 40 and the inner wall of the duct assembly 2, but also a small portion of the air flows between the inflow ends of the two flow dividing plates 40 and along the passages formed by the two flow dividing plates 40, and finally is also guided to the two air outlet 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 inflow 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 duct assembly 2 to the channel between the inner walls of the air duct assembly 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.

It will be appreciated that, since the inflow end of the second splitter plate 42 is disposed to extend upstream of the inflow end of the first splitter 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 splitter plate 41 and the second splitter plate 42 is guided to the first air outlet duct 232a, the uniformity of the air flowing in the first air outlet duct 232a and the second air outlet duct 232b can be further improved.

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.
