In some embodiments, centrifugal fan 200 includes an impeller 210, with the axis of impeller 210 being parallel or perpendicular to base plate 120 of housing 100.
Alternatively, as shown in fig. 7 and 8, the centrifugal fan 200 further includes a volute 220, and the fan assembly further includes two partitions 300, each partition 300 corresponding to one centrifugal fan 200. The volute 220 defines a volute air channel in which the impeller 210 is located; the first end of the volute air channel is an air suction inlet 221 of the centrifugal fan 200, and the second end is an air outlet 222 of the centrifugal fan 200; the partition 300 is provided with a mounting port 310; the scroll 220 is located at one side of the partition 300, the second end of the scroll duct is installed on the partition 300, and the exhaust port 222 corresponds to the installation port 310.

Alternatively, the axes of the impellers 210 of the centrifugal fans 200 are disposed parallel to the bottom plate 120 of the casing 100, and the axes of the impellers 210 of the two centrifugal fans 200 are parallel to each other. Centrifugal fan 200 also includes a single-shaft motor 230 and a motor mount 250. The motor base 250 is disposed on the partition 300 and corresponds to the single-shaft motor 230, and is used for mounting and fixing the single-shaft motor 230. Thus, both the scroll 220 and the motor housing 250 are mounted on the partition 300.
Alternatively, the axes of the impellers 210 of the centrifugal fans 200 are disposed parallel to the bottom plate 120 of the casing 100, and the axes of the impellers 210 of the two centrifugal fans 200 are parallel to each other. As shown in fig. 6, centrifugal fan 200 further includes a dual-output motor 240 and a motor mount 250. The motor base 250 is disposed on the partition 300 and corresponds to the dual-output motor 240, so as to mount and fix the dual-output motor 240. Thus, both the scroll 220 and the motor housing 250 are mounted on the partition 300.
Alternatively, the axis of the impeller 210 of the centrifugal fan 200 is disposed perpendicular to the bottom plate 120 of the casing 100, and the centrifugal fan 200 is mounted in a lying manner. The centrifugal fan 200 includes a single-shaft motor 230 and a motor base 250, as shown in fig. 9, the single-shaft motor 230 is disposed below the impeller 210, and the driving shaft penetrates through the impeller 210, and the motor base 250 is disposed below the single-shaft motor 230 and is fixed on the bottom plate 120 of the casing 100. The upper surface of the motor housing 250 is provided with a plurality of holders 251. Thus, the single-shaft motor 230 is fixed through the motor base 250, and the volute 220 is supported through the bracket 251, so that the centrifugal fan 200 is more stable.
Alternatively, the impeller 210 of the centrifugal fan 200 is disposed perpendicular to the bottom plate 120 of the casing 100, and the centrifugal fan 200 is mounted in a lying manner. The centrifugal fan 200 includes a single-shaft motor 230 and a motor base 250, the single-shaft motor 230 is disposed above the impeller 210, the driving shaft penetrates through the impeller 210, the motor base 250 is disposed above the single-shaft motor 230 and fixed on the top plate of the casing 100, and the motor base 250 is used for fixing the single-shaft motor 230. This lifts the single-shaft motor 230 by the motor mount 250.
In some embodiments, the air duct assembly is located between two centrifugal fans 200, the air duct assembly includes two air duct sidewalls 260, and the two air duct sidewalls 260 are respectively opposite to the air outlets 222 of the two centrifugal fans 200; the outlet air from the outlet 222 is blown along the duct sidewall 260 toward the outlet 112. Indoor air enters the casing 100 from the air inlet 111, the impeller 210 sucks the air in the casing 100 into the volute air channel from the air suction inlet 221 through centrifugal force when rotating, and after being compressed, the air is blown to the air channel side wall 260 from the air outlet 222, and finally the air is blown into the room along the air channel side wall 260.
Optionally, the air duct side wall 260 is configured with two adjacent curved surfaces, and the bending directions of the two curved surfaces are the same; the fan assembly and the air outlet 112 are both located on the same side of the two curved surfaces, and the air outlet direction of the fan assembly faces the air duct side wall 260, so that the air outlet of the fan assembly blows to the air outlet 112 along the two curved surfaces. Indoor air enters the casing 100 from the air inlet 111, and under the blowing action of the centrifugal fan 200, the air in the casing 100 circulates along the air duct side wall 260 to the air outlet 112, and finally is blown into the room. Because the air duct side wall 260 is configured with two adjacent curved surfaces, when the centrifugal fan 200 blows air towards the air duct side wall 260, air flows along the two curved surfaces to the air outlet 112, and at the moment, noise generated by air wake flow at the tail end of the air duct side wall 260 is small, and the air outlet of the air outlet 112 is uniform.
Alternatively, the two adjacent curved surfaces are respectively referred to as a first curved surface 261 and a second curved surface 262, where the first curved surface 261 is close to the centrifugal fan 200, the second curved surface 262 is close to the air outlet 112, and a tangent line at the end of the first curved surface 261 intersects with the second curved surface 262. The centrifugal fan 200 blows air to the first curved surface 261, that is, all the air outlet of the centrifugal fan 200 falls on the first curved surface 261, and when the air flows to the end of the first curved surface 261, the air has two circulation directions: one is directed vertically toward the air outlet 112, and the other is along a tangent line at the end of the first curved surface 261. Next, air flowing along a tangent line at the end of the first curved surface 261 is blown toward the second curved surface 262, and when the air flows to the end of the second curved surface 262, the air has two flowing directions: one vertically toward the air outlet 112 and the other along a tangent line at the end of the second curved surface 262. It can be seen that when the air circulates on the two curved surfaces, part of the air vertically flows out towards the air outlet 112, so that the air outlet is relatively uniform. And the duct sidewall 260 is configured with two adjacent curved surfaces, compared to using one curved surface to guide the centrifugal fan 200 to exhaust air to the air outlet 112, since the air flowing along the tangent line at the end of the first curved surface 261 is further guided by the second curved surface 262, the air is buffered and flows along two directions at the end of the second curved surface 262, so that the noise generated by the air wake at the end of the second curved surface 262 is small. In the case that the centrifugal fan 200 simultaneously blows air to the first curved surface 261 and the second curved surface 262, that is, the air outlet of the centrifugal fan 200 simultaneously falls on the first curved surface 261 and the second curved surface 262, the effects of uniform air outlet and low noise are also achieved.
Alternatively, the first curved surface 261 and the second curved surface 262 are both arc curved surfaces. The first curved surface 261 and the second curved surface 262 have the same radian.
Alternatively, the first curved surface 261 and the second curved surface 262 are both arc curved surfaces. The first curved surface 261 and the second curved surface 262 have different radians.
Optionally, as shown in fig. 4, a rounded corner is disposed at the connection between the first curved surface 261 and the second curved surface 262. In the case where a tangent line at the end of the first curved surface 261 does not intersect with the second curved surface 262, when air flows to the end of the first curved surface 261, the air has two flow directions: one vertically toward the air outlet 112 and the other along the rounded corner toward the second curved surface 262. In this way, the air of the first curved surface 261 can be guided to circulate toward the second curved surface 262 by the rounded corners.
Alternatively, the first curved surface 261 is an inner concave surface, and the second curved surface 262 is an outer convex surface. The first curved surface 261 shown in fig. 4 is an inner concave surface, and the second curved surface 262 is opposite to the protruding direction of the cambered surface of the first curved surface 261 (not shown in the figure). The fan assembly blows air towards the air duct side wall 260, and because the second curved surface 262 is the outer convex surface, compared with the inner concave windward surface, the outer convex windward surface is easier to break the wall attaching effect of wind, reduces the phenomenon that wind advances along the air duct, accelerates the wind redirecting effect of the outward convex air duct, and improves the uniformity of the air outlet 112. Meanwhile, the rear end of the first curved surface 261 is connected with the second curved surface 262 which is convex inwards, so that the wall attaching effect of wind at the rear end of the first curved surface 261 is broken, the wind blows to the heat exchange assembly, and the uniformity of the wind outlet 112 is improved. In this embodiment, in the case that the first curved surface 261 is the fastest curved surface, the air outlet efficiency and the air outlet uniformity can be effectively improved.
In some embodiments, as shown in fig. 2 and 3, one air outlet 112 and two air inlets 111 are disposed on the front side plate 110 of the casing 100, and the two air inlets 111 are located on two sides of the air outlet 112. The air inlets 221 of the two centrifugal fans 200 are respectively disposed at the two air inlets 111, and the air outlets 222 of the two centrifugal fans 200 are disposed opposite to each other. The two air duct side walls 260 are symmetrically disposed between the two centrifugal fans 200, and the air outlet 222 of each centrifugal fan 200 faces one air duct side wall 260 to guide the air outlet 112 of the two centrifugal fans 200 to circulate, as shown in fig. 5. The two adjacent curved surfaces of the air duct sidewall 260 are respectively referred to as a first curved surface 261 and a second curved surface 262, wherein the first curved surface 261 is close to the fan assembly, and the second curved surface 262 is close to the air outlet 112. The ends of the second curved surfaces 262 of the two tunnel sidewalls 260 are connected.
In the above embodiment, the exhaust ports 222 of the two centrifugal fans 200 are disposed opposite to each other, and the two air duct sidewalls 260 are symmetrically disposed between the two centrifugal fans 200. It can be seen that in the case where the air outlet 112 is long, it is difficult to use a conventional duct type air duct. The reason is that the conventional duct type air duct needs to be connected with the air outlet 222 of the centrifugal fan 200 and the air outlet 112 of the casing 100 through two ends of the air duct, and the port of the air duct is limited in size, so that it is difficult to adapt to the long air outlet 112. However, the present invention only needs to provide two symmetrical air duct sidewalls 260 as shown in fig. 5, and the manufacturing cost is reduced compared to the conventional duct type air duct.
In the above embodiment, the ends of the second curved surfaces 262 of the two air duct side walls 260 are connected. The air discharged from the air outlet 222 of each centrifugal fan 200 uniformly circulates to the air outlet 112 along two adjacent curved surfaces of the corresponding air channel side wall 260, and when the air discharged from the air outlet 222 of the two centrifugal fans 200 circulates to the end of the second curved surface 262, the air circulates along the tangent line of the end of the corresponding curved surface. Since the two air duct side walls 260 are symmetrical and the ends of the two second curved surfaces 262 are connected, after the wind forces act on each other when the two air portions meet, the two air portions originally flowing along the tangent line of the ends of the corresponding second curved surfaces 262 vertically flow towards the air outlet 112, so that the air outlet at the joint of the two second curved surfaces 262 is more uniform, as shown in fig. 5.
In some embodiments, at least one of the first curved surface 261 and the second curved surface 262 is configured as a curved surface that fits the fastest curve. The line segment between the two points is the shortest, but the path between the two points with the fastest speed is the 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. The surface that fits to the fastest curve is referred to herein as the fastest surface.
Alternatively, the first curved surface 261 is an arc curved surface, and the second curved surface 262 is a fastest curved surface. When the air outlet of the fan assembly circulates along the second curved surface 262 towards the air outlet 112, the air can be quickly blown towards the air outlet 112 due to the adoption of the fastest curved surface by the second curved surface 262, so that the air outlet speed of the indoor unit is improved. In addition, the air blown by the fan assembly at different positions on the second curved surface 262 at the same time, or the air blown by the fan assembly at different positions on the second curved surface 262 along the first curved surface 261 at the same time, can be simultaneously circulated to the tail end of the second curved surface 262, so that the air outlet of the second curved surface 262 of the air duct side wall 260 is more uniform.
Alternatively, both the first curved surface 261 and the second curved surface 262 are fastest curved surfaces. Therefore, the air outlet rate of the indoor unit can be further improved, and the air outlet is more uniform.
In some embodiments, the heat exchange assembly includes a heat exchanger 400, the heat exchanger 400 covering the air outlet 112 or the air inlet 111. If the heat exchanger 400 is disposed at the air inlet 111, air exchanges heat with the heat exchange component when entering the casing 100 from the air inlet 111; if the heat exchanger 400 is disposed at the air outlet 112, the air exchanges heat with the heat exchange assembly when being blown into the room from the air outlet 112.
Alternatively, the heat exchanger 400 is configured in a U shape with the opening of the U shape facing the air outlet 112 or the air inlet 111. Thus, the U-shaped heat exchanger 400 can increase the heat exchange area and improve the refrigerating or heating efficiency of the indoor unit.
Alternatively, the heat exchanger 400 is configured in a plate shape, and the plate surface thereof is parallel to the plane in which the air outlet 112 or the air inlet 111 is located. In this way, the heat exchanger 400 having a plate shape parallel to the plane of the air outlet 112 or the air inlet 111 is used, so that installation space in the casing 100 can be saved.
Alternatively, the heat exchanger 400 is configured in a plate shape, and the plate surface thereof is inclined to the plane of the air outlet 112 or the air inlet 111. Compared with the plate-shaped heat exchanger 400 which is parallel to the plane of the air outlet 112 or the air inlet 111, the plate-shaped heat exchanger 400 which is inclined to the plane of the air outlet 112 or the air inlet 111 is adopted, so that the heat exchange area can be increased, and the refrigerating or heating efficiency of the indoor unit can be improved.
Optionally, a heat exchange component is disposed at the air inlet 111, and a purification component is disposed at the air outlet 112. The heat exchange component is used for exchanging heat with the air in the way, and the purification component is used for purifying the air in the way. Air enters the machine shell 100 from the air inlet 111 and exchanges heat with the heat exchange component, and air in the machine shell 100 is purified by the purification component when entering the room from the air outlet 112, so that the air quality of the air outlet of the indoor unit is improved.
