Embodiments of the present disclosure provide a purification module as shown in fig. 1-3.
The purification module includes a purification chassis 500, a purification assembly 513, a purification blower assembly 600, and a purification redirection air duct 620. The same side plate of the purifying enclosure 500 is provided with a purifying air inlet 511 and a purifying air outlet 512, the purifying component 513 is arranged in the purifying enclosure 500, and the purifying fan component 600 is arranged in the purifying enclosure 500. The purification redirection air duct 620 is disposed in the wind field between the purification blower assembly 600 to the purification assembly 513 to guide the wind blown from the purification blower assembly 600 to the purification air outlet 512. Alternatively, the purge fan assembly 600 is a blower centrifuge. The air blowing type or the air suction type can be divided according to the relation between the fan and the purifying component. Wherein, after blowing formula is that the fan is induced drafted from inlet scoop department, blows to purifying component, optionally, purifying component sets up in purifying air outlet department.
As shown in fig. 1 and 2, with the purification module provided in the embodiment of the present disclosure, indoor air enters the enclosure 500 from the purification air inlet 511, and under the blowing action of the purification blower assembly 600, the air in the purification enclosure 500 is redirected under the action of the purification redirecting air duct 620, blown to the purification air outlet 512, and finally blown into the room, so as to complete the air purification of the indoor space of the user. Optionally, the air blown by the purifying fan assembly 600 is redirected by 90 ° by the purifying redirecting air duct 620, and then is blown out from the purifying air outlet 512 through the purifying assembly 513. Optionally, a purge assembly 513 is provided at the purge outlet 512.
By arranging the purification redirection air duct 620 in the air field, the air blown out by the purification fan assembly 600 can be redirected, and finally, the air is smoothly blown out from the purification air outlet 512, so that the purification module is realized that the purification air inlet 511 and the purification air outlet 512 are arranged on the same side plate of the purification machine shell 500. When the internal components of the purification module need to be maintained or replaced, only the side plate provided with the purification air inlet 511 and the purification air outlet 512 needs to be detached, so that the disassembly, assembly and maintenance of the purification module are simplified.
Optionally, the purification housing is a cuboid structure, and the purification module may be mounted to a ceiling of a user. Alternatively, the purification module may be installed as a functional module of the air conditioner together with the indoor heat exchange module to the ceiling for use.

Optionally, the purge assembly 513 includes an air filter covering either the purge outlet 512 or the purge inlet 511. Types of air filters include, but are not limited to, HEPA filters, fiberglass filters, electrostatic filters, activated carbon fiber filters.
Optionally, the windward side of the purge redirect air duct 620 is curved or beveled. Thus, the air blown out from the purge air outlet 610 of the purge fan assembly 600 can be smoothly guided to the purge air outlet 512. Wherein, the curved purification redirection air duct 620 can be seen in fig. 2, and the inclined purification redirection air duct is similar to the redirection air duct in fig. 7.
Optionally, the windward side of the purification redirection air duct 620 is an inner concave surface, and the cross section of the inner concave surface is the fastest curve.
Similar to the redirection air duct 260 described below, the cross-section of the purge redirection air duct 620 may also be the fastest curve. When the air outlet of the purifying fan assembly 600 moves along the purifying redirecting air duct 620 with the fastest curve, air can be quickly blown to the purifying air outlet 512, and the air outlet rate of the purifying module is improved. And, the purifying fan assembly 600 blows the air at different positions of the purifying redirecting air duct 620 at the same time, and can flow the rear end of the purifying redirecting air duct 620 at the same time, so that the air outlet after being redirected by the purifying redirecting air duct 620 is more uniform.
Optionally, a longitudinal air guide grid 6201 is disposed on the windward side of the purifying and redirecting air duct, wherein an included angle c between an circumscribed line 6202 of the windward side on which the air guide grid is disposed and the purifying component 513 is smaller than an included angle d between the air guide grid 6201 and the purifying component. As shown in fig. 2.
The portion of the wind blown out from the purge outlet 610 moves a distance along the purge redirection wind path due to the coanda effect. The arrangement of the air guide grid 6201 in this embodiment breaks the wall attaching effect of the air, so that the air is discharged from the purification air outlet 512, and the air outlet uniformity of the purification air outlet 512 is improved. This effect is similar to the effect of redirecting air ducts breaking the coanda effect hereinafter. Alternatively, the air guiding bars 6201 are triangular cone-shaped structures longitudinally disposed in the purification redirection air duct 620. Longitudinal is understood to be perpendicular to the user's ground. Fig. 2 is a schematic cross-sectional view of a purge redirection air duct 620 provided with air directing bars 6201.
Optionally, the purge redirection air duct 620 includes an upper purge redirection air duct 621 and a lower purge redirection air duct 622. As shown in fig. 3. The upper purge redirecting air duct 621 guides the upper air blown out from the purge fan assembly 600 to the purge air outlet 512, and the upper purge redirecting air duct 621 is provided with first air guide bars 6211. The lower purge redirecting air duct 622 guides the lower air blown from the purge fan assembly 600 to the purge air outlet 512, and the lower purge redirecting air duct 622 is provided with second air guide bars 6221. Wherein the first air guiding grating 6211 is located in front of the second air guiding grating 6221, or the first air guiding grating 6211 is located behind the second air guiding grating 6221.
The first air guiding grid bars 6211 and the second air guiding grid bars 6221 are arranged in sequence, so that the air blown out from the purification air outlet 610 can be guided to be blown out from different positions of the purification air outlet 512, and the air outlet uniformity of the purification air outlet 512 is improved. Optionally, the upper purge redirection air duct 621 is provided with a plurality of first air guide bars 6211, and similarly, the lower purge redirection air duct 622 is provided with a plurality of second air guide bars 6221. As shown in fig. 3.

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.
As shown in fig. 5 and 6, with the indoor heat exchange module provided in the embodiment of the present disclosure, indoor air enters the casing 100 from the air inlet 111, and under the blowing action of the fan assembly, the air in the casing 100 is redirected under the action of the redirecting air duct 260, and is blown to the air outlet 112, and finally is blown into a room. 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 indoor heat exchange module 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 indoor heat exchange module need to be maintained or replaced, only the side plate provided with the air inlet 111 and the air outlet 112 needs to be detached, so that the disassembly, assembly and maintenance of the indoor heat exchange module are simplified.
Alternatively, the indoor heat exchange module may be an air duct machine. 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. 5. 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 heat exchange module 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.

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. 11, 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.

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.

The first protruding wind guiding section 2631 is used for breaking the coanda effect of wind, so that the wind blows from the first protruding wind guiding section 2631 to the air outlet 112; similarly, the lower windward section 264 is also a concave curved surface, and is provided with a protrusion, i.e., a second convex wind guiding section 2641. The second protruding wind guiding segment 2641 is used for breaking the coanda effect of wind, so that wind blows from the second protruding wind guiding segment 2641 to the air outlet 112. The first protruding wind guiding section 2631 and the second protruding wind guiding section 2641 are arranged back and forth, and guide wind blows out from different positions of the air outlet 112, so that the air outlet uniformity of the air outlet 112 is improved.

It is to be understood that the foregoing embodiments of the "redirecting air duct" may be used for both the "first redirecting air duct" and the "second redirecting air duct" herein, and will not be repeated herein. Optionally, the first redirecting air duct and the second redirecting air duct are symmetrically arranged.
The indoor heat exchange module 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. 5, the cabinet 100 of the indoor heat exchange module 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.

In the above embodiment, the exhaust ports 222 of the two centrifugal fans 200 are disposed opposite to each other, and the two redirecting air channels 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.
