Referring to fig. 1-15, an embodiment of the present disclosure provides an air conditioning indoor unit comprising a cabinet 100, a heat exchange assembly, a fan assembly, and a redirection air duct 260. Wherein, the same side plate of the casing 100 is provided with an air outlet 112 and an air inlet 111. The heat exchange assembly is disposed within the housing 100. The heat exchange assembly is located at the air outlet 112 or the air inlet 111. The fan assembly is disposed within the housing 100. The redirecting air duct 260 is disposed in the wind field between the fan assembly and the heat exchange assembly to guide the wind blown by the fan assembly to the air outlet 112.

Optionally, the redirecting air duct 260 redirects the air from the fan assembly 90 ° before it is blown out of the heat exchange assembly.

By arranging the redirecting air duct 260 in the air field, the air blown out by the fan assembly can be redirected and finally smoothly blown out from the air outlet 112, so that the air conditioner indoor unit is realized that the air inlet 111 and the air outlet 112 are arranged on the same side plate of the casing 100. When the internal components of the air conditioner indoor unit are required to be maintained or replaced, only the side plate provided with the air inlet 111 and the air outlet 112 is required to be detached, so that the disassembly, assembly and maintenance of the air conditioner indoor unit are simplified.

Alternatively, the air conditioning indoor unit may be an air duct unit. Alternatively, the air inlet 111 and the air outlet 112 may be provided at the front panel 110 of the cabinet, as shown in fig. 1. In this way, when the air duct machine needs to be disassembled and maintained, only the front air outlet grille needs to be disassembled. Alternatively, the air inlet and the air outlet may be provided at the lower panel of the cabinet 100. Generally, the area of the lower part of the suspended ceiling decorated by the user is larger, and the air inlet and the air outlet are arranged on the lower panel of the casing, so that the area of the air inlet and the area of the air outlet can be increased, and meanwhile, the replacement and maintenance of the internal structural parts of the indoor unit of the air conditioner are facilitated.

Optionally, the redirecting air duct 260 projects onto a plane where the air outlet 222 of the fan assembly is located, and the obtained projected area is greater than or equal to the area of the air outlet 222 of the fan assembly.

The redirecting air duct 260 is used for redirecting the air blown out from the air outlet 222 of the fan assembly. In the embodiment of the disclosure, the projection area of the redirecting air duct 260 is greater than or equal to the area of the air outlet 222 of the fan assembly, so that the air blown out from the air outlet 222 of the fan assembly can be totally redirected and blown out from the air outlet 112, the redirecting effect of the air blown out from the air outlet 222 of the fan assembly is improved, and meanwhile, the heat exchange effect of the heat exchange assembly is improved.

Optionally, the redirecting air duct includes a beveled and/or curved surface.

Alternatively, the windward side of the redirecting air duct may be beveled, sloping from the air outlet 222 of the fan assembly to the heat exchange assembly, as shown in FIG. 3. Alternatively, the windward side of the redirecting air duct may be curved, as shown in fig. 5 and 6.

Optionally, the redirecting air duct includes a first windward segment 261 and a second windward segment 262. The first windward segment 261 is adjacent to the air outlet 222 of the fan assembly. The second windward segment 262 extends along the first windward segment 261 and is remote from the air outlet 222 of the fan assembly. Wherein, the first windward segment 261 is an inclined plane, and the second windward segment 262 is a curved plane.

As shown in fig. 4, the first windward section 261 of the redirecting air duct is an inclined surface, and the second windward section 262 is a curved surface. The wind has coanda effect, and a part of the wind blown by the wind channel component is redirected under the action of the redirecting wind channel 260, and is blown out after passing through the heat exchange component, and the other part of the wind is forwarded along the redirecting wind channel 260. In the embodiment of the disclosure, the redirecting air duct 260 is divided into at least two windward sections, when wind advances along the first windward section 261 under the action of the coanda effect, the coanda effect of the wind of the first windward section 261 is broken by the connection part of the curved surface and the inclined surface due to the curved surface 262, so that the wind is blown to the heat exchange assembly from the rear end of the first windward section 261, the heat exchange uniformity of the heat exchange assembly is improved, and the wind outlet uniformity at the air outlet 112 is also improved.

Optionally, the redirecting air duct 260 is curved, including an inner concave surface and an outer convex surface. Wherein the inner concave surface and/or the outer convex surface is a windward surface.

The concave facing surface of the redirecting air duct 260 is shown in the first facing section 261 of fig. 5, and the convex facing surface of the redirecting air duct 260 is shown in the second facing section 262 of fig. 5. The windward side of the redirecting air duct 260 may be all concave surfaces, all convex surfaces, or a combination of concave surfaces and convex surfaces, so as to smoothly redirect the wind blown out by the fan assembly, guide the wind to the heat exchange assembly, and finally blow out from the air outlet 112.

Optionally, the redirecting wind tunnel 260 includes a first windward segment 261 and a second windward segment 262. The first windward segment 261 is adjacent to the air outlet 222 of the fan assembly. The second windward segment 262 extends along the first windward segment 261 and is remote from the air outlet 222 of the fan assembly. Wherein, the first windward segment 261 is an inner concave surface, and the second windward segment 262 is an outer convex surface and/or an inner concave surface.

As shown in fig. 5, the first windward segment 261 is a concave inner surface, and the second windward segment 262 is a convex outer surface. Part of the wind blown out by the fan assembly will travel a distance along the first upwind section 261, which is concave inward. In this embodiment, the second windward section 262 is an outer convex surface, and compared with the inner concave windward section, the outer convex windward section breaks the wall attaching effect of the wind more easily, reduces the phenomenon that the wind advances along the wind channel, accelerates the wind redirecting effect of the outward convex wind channel, and improves the uniformity of the wind outlet 112. Meanwhile, the rear end of the first inward concave windward section 261 is connected with the second outward convex windward section 262, and the wall attaching effect of wind at the rear end of the first windward section 261 is broken, so that the wind blows to the heat exchange component, and the air outlet uniformity of the air outlet 112 is improved.

Optionally, the first windward segment 261 is an inner concave surface, and the second windward segment 262 is an inner concave surface.

Two consecutive concave facing surfaces facilitate breaking the coanda effect of the wind as shown in fig. 7. Part of the wind blown out by the fan assembly can advance along the first windward section 261, when the wind moves to the junction of the first windward section 261 and the second windward section 262, the coanda effect of the wind is broken, the wind does not continue to advance along the redirecting air duct but blows to the heat exchange assembly, the uniformity of the air outlet at the air outlet 112 is improved, and the wind is not concentrated to the air outlet 112 corresponding to the rearmost end of the redirecting air duct 260 to blow out.

Optionally, the concave inner surface includes a front end and a rear end along a direction of wind blowing of the fan assembly, wherein a tangent line of the rear end of the concave inner surface is perpendicular to the heat exchange assembly.

It can be understood that the front end of the inner concave surface is one end close to the air outlet 222 of the fan assembly, and the rear end of the inner concave surface is one end far away from the air outlet 222 of the fan assembly. The circumscribed line of the rear end of interior concave surface perpendicular to heat transfer assembly is favorable to making the wind of interior concave surface blow to heat transfer assembly entirely, has improved heat transfer assembly's heat transfer effect, has improved the air-out homogeneity of air outlet 112 department.

Optionally, an area of the first windward segment 261 is less than or equal to an area of the second windward segment 262.

The first windward segment 261 is closer to the air outlet 222 of the fan assembly than the second windward segment 262, and the coanda effect of the wind on the first windward segment 261 is more pronounced due to the sinking action of the wind. In this embodiment, the area of the second windward segment 262 is greater than or equal to the area of the first windward segment 261, so that the wall attachment effect of wind is reduced as a whole, and the uniformity of the air outlet at the air outlet 112 is improved.

Optionally, the first windward segment 261 includes a first front end and a first rear end, and the second windward segment 262 includes a second front end and a second rear end along a direction of wind blowing of the fan assembly. The first tangent line 2611 at the first rear end forms a first included angle with the heat exchange assembly, and the second tangent line 2621 at the second front end forms a second included angle with the heat exchange assembly, wherein the first included angle is larger than the second included angle.

It will be appreciated that the first forward end of the first windward segment 261 is closer to the air outlet 222 of the fan assembly than the first aft end. The second front end of the second windward segment 262 is closer to the air outlet 222 of the fan assembly than the second rear end. Alternatively, "front end" may be understood as being at the front end point and "back end" may be understood as being at the back end point.

As shown in fig. 8, the first tangent line 2611 of the first rear end forms a first included angle a with the heat exchange assembly, the second tangent line 2621 of the second front end is parallel or nearly parallel to the heat exchange assembly, and the included angle between the second tangent line 2621 and the heat exchange assembly is 0 ° or nearly 0 °. In this embodiment, the first included angle a is larger than the second included angle, so that the coanda effect of the wind at the first rear end of the first windward section 261 is broken, and the air is cut from the first rear end and blown to the heat exchange assembly instead of continuing to flow to the second windward section 262 in an adherence manner, thereby improving the uniformity of the air outlet at the air outlet 112.

The larger the first included angle is, the smaller the second included angle is, the larger the difference between the first included angle and the second included angle is, and the wall attaching effect of wind at the first rear end of the first windward section 261 is easier to break, so that the wind blows from the first rear end of the first windward section 261 to the air outlet. Optionally, the first included angle is greater than or equal to 30 ° and less than or equal to 90 °. The second included angle is greater than or equal to 0 deg. and less than or equal to 20 deg..

As shown in fig. 9, the third tangent 2622 of the second rear end forms a third included angle b with the heat exchange assembly. The larger the third included angle, the more favorable it is for guiding the wind of the second rear end of the second windward segment 262 to the heat exchange assembly smoothly. Optionally, the third included angle is greater than or equal to 75 ° and less than or equal to 90 °.

Optionally, the cross section of the first windward section and/or the second windward section is the fastest curve.

The distance between the two points is the shortest, but the path with the highest speed between the two points is a curve. For example, on an incline, two tracks are swung, one being a straight line and one being a curved line, the starting point height and the ending point height being the same. Two pellets of the same mass and size simultaneously slide down from the starting point, whereas the pellets of the curve reach the ending point first. Whereas the fastest curve among the numerous curves can bring the pellet to the end point fastest. The fastest curve is a cycloid, which is a track formed by a fixed point on a circle when the circle moves along a straight line. And, the object that initial coordinate is different is the same and is sliding motion downwards on the fastest curve, can arrive the terminal point at the same moment.

When the windward sides of the first windward segment 261 and the second windward segment 262 are concave, as shown in fig. 7, the cross section of the first windward segment 261 and/or the second windward segment 262 is the fastest curve. When the air outlet of the fan assembly moves along the first windward section 261 and the second windward section 262 of the fastest curve type, air can be quickly blown to the air outlet 112, and the air outlet speed of the indoor unit is improved. In addition, the air blown by the fan assembly at different positions on the first windward section 261 and/or the second windward section 262 at the same time can flow to the rear ends of the first windward section 261 and/or the second windward section 262 at the same time, so that the air outlet of the first windward section 261 and/or the second windward section 262 of the redirecting air duct 260 is more uniform.

Optionally, the first windward segment 261 projects to a plane where the air outlet of the fan assembly is located, so as to obtain a first projection area, and the second windward segment 262 projects to a plane where the air outlet of the fan assembly is located, so as to obtain a second projection area. The sum of the first projection area and the second projection area is larger than or equal to the area of the air outlet of the fan assembly.

It will be understood that, as shown in fig. 7, the first windward section 261 and the second windward section 262 of the redirecting air duct 260 are projected in the direction where the windward side faces the air outlet 222 of the fan assembly, that is, the projection is made to the left in the drawing, and the sum of the first projection and the second projection overlaps with the air outlet 222 of the fan assembly, or the part of the sum of the first projection and the second projection overlaps with the air outlet 222 of the fan assembly. The redirecting air duct 260 is used for redirecting the air blown out from the air outlet 222 of the fan assembly. In the embodiment of the disclosure, the sum of the first projection area and the second projection area is greater than or equal to the area of the air outlet 222 of the fan assembly, so that the air blown out from the air outlet 222 of the fan assembly can be totally redirected and blown out from the air outlet 112, the redirecting effect of the air blown out from the air outlet 222 of the fan assembly is improved, and meanwhile, the heat exchange effect of the heat exchange assembly is improved.

Optionally, the first projected area is less than or equal to the second projected area.

The first windward segment 261 is closer to the air outlet 222 of the fan assembly than the second windward segment 262, and the coanda effect of the airflow on the first windward segment 261 is greater. To reduce the ratio of the total blow of wind in the fan assembly where coanda effect exists, the area of the second windward segment 262 is greater than the area of the first windward segment 261, and it is also understood that the area of the second projection is greater than or equal to the area of the first projection. In this way, the second windward section 262 distributes more wind to be redirected, reducing the coanda effect of the total blowing, improving the redirecting efficiency of the redirecting air duct 260, and further improving the air outlet uniformity and the air outlet efficiency of the wind at the air outlet 112.

Optionally, the redirecting air duct 260 includes an upper windward section 263 and a lower windward section 264. The upper windward section 263 guides the upper wind blown out by the fan assembly to the first position of the air outlet 112 for blowing out, and the lower windward section 264 guides the lower wind blown out by the fan assembly to the second position of the air outlet 112 for blowing out. Wherein the first position is different from the second position. As shown in fig. 10.

The redirecting air duct 260 is used to redirect the wind blown by the fan assembly. During the redirecting process, after the air blown by the fan assembly is blown to the redirecting air duct 260, part of the air will generate a wall-attaching effect and move along the redirecting air duct 260. In this embodiment, the redirecting air duct 260 is divided into an upper windward section 263 and a lower windward section 264. The upper windward section 263 guides the upper wind to the first position of the air outlet 112, and the lower windward section 264 guides the lower wind to the second position of the air outlet 112, so that the redirecting air duct 260 guides the wind blown out by the fan assembly to blow out from different positions of the air outlet 112, and the uniformity of the air outlet at the air outlet 112 is improved.

Optionally, the upper windward section 263 includes a first protruding wind guiding section 2631, the first protruding wind guiding section 2631 for guiding out wind moving along the upper windward section 263; the lower windward section 264 includes a second protruding wind guiding section 2641, the second protruding wind guiding section 2641 for guiding out wind moving along the lower windward section 264. Wherein the first protruding wind guiding section 2631 is located in front of the second protruding wind guiding section 2641, or the first protruding wind guiding section 2631 is located behind the second protruding wind guiding section 2641.

As shown in fig. 10, the upper windward section 263 is a concave curved surface, and the concave curved surface is provided with a protrusion, i.e., a first convex wind guiding section 2631.

Optionally, the first redirecting air duct and the second redirecting air duct are symmetrically arranged.

The indoor unit of the air conditioner comprises a heat exchange cavity provided with a heat exchange assembly and a fan cavity provided with a fan assembly. The fan cavity comprises a first fan cavity and a second fan cavity, and the two fan cavities are respectively arranged at the left side and the right side of the heat exchange cavity. The heat exchanger 400 in the heat exchange cavity is disposed at the air outlet 112.

In some embodiments, as shown in fig. 1, the cabinet 100 of the indoor unit is constructed in a rectangular parallelepiped shape in a ceiling-mounted manner, and the bottom plate 120 of the cabinet 100 is horizontally disposed, and one side plate of the cabinet 100 faces indoors and is referred to as a front panel 110. The air inlet 111 and the air outlet 112 of the casing 100 are both arranged on the front panel 110, so that other side plates, a bottom plate 120 and a top plate of the casing 100 can be attached to a wall or a cabinet body according to decoration requirements, thereby achieving the effect of hiding the indoor unit and further improving decoration effects.

Alternatively, the fan assembly includes a centrifugal fan 200, the centrifugal fan 200 including an impeller 210, the axis of the impeller 210 being parallel or perpendicular to the bottom plate 120 of the housing 100.
