Description

Fresh air pipe rain cover and air conditioner

Technical Field

The utility model relates to the technical field of air conditioners, in particular to a fresh air pipe rain cover and an air conditioner.

Background

In the prior art, an air conditioner with a fresh air function generally has a fresh air duct extending outdoors. As shown in fig. 1, taking a new air duct as an example of a cylinder shape, the upper half part of the new air duct, which is exposed outside, is provided with a semi-cylindrical rainproof cover upper cover body, so that rainwater is prevented from being directly sprayed into the new air duct and sucked into the new air fan. The lower part of the rain-proof cover is usually provided with a grille, which comprises a circumferential grille extending along the circumference of the rain-proof cover and an axial grille extending along the axial direction of the rain-proof cover, and the holes between the axial grille and the circumferential grille form air inlets for the entry of outdoor air.

In rainy days, after the rainwater strikes the upper cover body of the semi-cylindrical rain cover, besides the water drops which are reflected and ejected out of the fresh air area, a large amount of rainwater can flow downwards along the surface of the rain cover, and the rainwater can flow to the lowest axial grille along the circumferential grille and drop from the axial grille. However, in the process that rainwater flows from the outer wall of the rain cover to the circumferential grille, the rainwater may be carried into the fresh air pipe rain cover by the sucked air flow, or small water drops splashed on the outer wall of the rain cover by the rainwater drops are condensed on the grille, so that the rainwater is sucked into the air conditioner indoor unit. The arrow in fig. 1, which represents the arrow tip by a broken line, shows the direction of movement of the water flow.

Disclosure of Invention

The utility model provides a new air pipe rain cover, which aims to solve the technical problem that rainwater of the existing new air pipe rain cover is easily brought into a new air pipe by new air flow.

The utility model provides a fresh air pipe rain cover, which comprises an upper cover body and a lower grille, wherein the lower grille comprises a circumferential grille, two ends of the circumferential grille are connected to the lower edge of the upper cover body, and water retaining ribs which extend along the length direction of the circumferential grille and are downwards convex are arranged on the outer surface of the circumferential grille at a part of the outer surface of the circumferential grille, which is close to one side of the inner end of the fresh air pipe rain cover.

The rain cover of the fresh air pipe has the beneficial effects that:

through setting up the protruding muscle of manger plate, can make the water droplet when flowing along circumference grid, can flow gradually to on the protruding muscle of manger plate of downwarping, and then increase the distance between water droplet position and the air intake, and the farther from the air intake, its wind speed is less more, fresh air stream is wrapped up in the ability weak more that gets into in the fresh air pipe rain-proof cover with water on the circumference grid, so, can reduce the suction that water received on the circumference grid, and then reduce the possibility that water on the circumference grid got into the fresh air pipe rain-proof cover. In addition, as the water retaining ribs are arranged on the outer surface of the circumferential grille, even if rainwater hung on the axial end faces of the water retaining ribs is upwards moved by the upward suction force, the upward movement distance is increased, the difficulty that the water is finally upwards brought into fresh air sucked by the fresh air pipe is increased, and therefore the possibility that the rainwater is sucked into a fresh air pipe can be reduced.

In a preferred technical scheme, the water retaining ribs extend from one end of the circumferential grille to the other end.

The water retaining ribs extend from one end of the circumferential grille to the other end, and all coverage of the outer surface of the circumferential grille on the circumferential angle can be achieved, so that rainwater can flow to the water retaining ribs no matter in any circumferential position when flowing along the circumferential grille provided with the water retaining ribs, and the possibility that the rainwater on the circumferential grille is sucked by fresh air is reduced.

In the preferable technical scheme, the size of the water retaining ribs in the axial direction of the fresh air pipe rain cover is smaller than that of the circumferential grille in the axial direction of the fresh air pipe rain cover.

Moreover, because the water retaining rib is thinner than the circumferential grille, when rainwater flows to the outer circumferential surface of the water retaining rib, the water retaining rib is smaller than the circumferential grille, so that water drops can be converged more quickly and drop down quickly, the stay time of the water retaining rib on the surface of the water retaining rib is shortened, and the possibility that the water retaining rib is brought into a new air pipe by the air inlet flow is reduced.

In the preferred technical scheme, the number of the water retaining convex ribs is 1-10, and the water retaining convex ribs are distributed on adjacent circumferential grids.

The number of the water retaining ribs is selected to be in the range, and the water retaining ribs can be concentrated at a plurality of circumferential grids with larger wind power of the fresh air pipe rain cover, so that the utilization rate of the water retaining ribs is improved. As for a plurality of circumferential grids far away from the inner end of the rain cover of the fresh air pipe, water retaining convex ribs are not required to be arranged due to the fact that the wind speed is small.

In the preferred technical scheme, the height of the water retaining ribs is less than 10mm.

The height of the water retaining convex ribs is selected to be in the range, so that the distance between water drops flowing on the surfaces of the water retaining convex ribs and the air inlet can be increased, and the possibility that rainwater is sucked is reduced. Moreover, when the height of the water retaining ribs is continuously increased, the improvement effect of the water retaining ribs on preventing rainwater from being sucked is not obvious, so that the water retaining ribs are arranged at the height above the water retaining ribs, and materials required for manufacturing the fresh air pipe rain cover can be saved.

In the preferred technical scheme, the fresh air pipe rain-proof cover further comprises an outer baffle, the outer baffle is located at the axially outermost end of the fresh air pipe rain-proof cover, a water diversion flange is arranged on the outer end face of the outer baffle, and the water diversion flange protrudes towards the direction deviating from the outer baffle.

Through setting up outer baffle, can prevent that the rainwater from receiving wind-force influence and slope to fall to the region between grid and the upper cover body down to in being brought into the fresh air duct by the fresh air flow that gets into the fresh air duct. And the water flow on the outer end surface of the outer baffle can be prevented from flowing to the lower edge of the outer baffle all the time by utilizing the water diversion flange and is suspended at the lower edge so as to be influenced by wind force of air inlet. The water diversion flange is protruded along the direction, so that when water drops or water flows leave the water diversion flange, the distance between the water drops or the water flows and the inner side surface of the outer baffle plate is increased, the falling wind speed is obviously reduced, and the possibility that the water drops or the water flows are sucked by fresh air flow is also reduced.

In a preferred technical scheme, the lower edge of the upper cover body is provided with a drainage groove, the drainage groove extends from one end of the upper cover body to the other end of the upper cover body, and the outer end of the drainage groove is open and lower than the inner end of the drainage groove; the outer baffle plate is adjacent to the bottom of the water drainage groove, and the outer ends of the two water drainage grooves are positioned between the two ends of the water diversion flange.

Through setting up outer end open-ended water drainage tank, make water drainage tank be located two lower edges of upper cover body circumference, so after the rainwater is hit the upper cover body, except by the water droplet that the splash popped up, the rainwater can flow downwards along the upper cover surface, flows to in the water drainage tank to through water drainage tank flow to the opening part of water drainage tank. When the water flow leaves the drainage tank, except that the water flow can flow downwards obliquely along the parabola when the water flow in the drainage tank is larger, as the outer baffle plate positioned at the axially outermost end of the fresh air pipe rain cover is adjacent to the tank bottom of the drainage tank, when the water flow in the drainage tank is smaller, the water flow separated from the tank bottom of the drainage tank can continue to flow along the outer surface of the outer baffle plate or the edge of the outer baffle plate, and the water flow cannot be brought into the fresh air pipe by the fresh air flow as easily as the water flow directly hangs at a certain horizontal or nearly horizontal lower edge.

The water diversion flange is arranged, the outer ends of the two water drainage grooves are positioned between the two ends of the water diversion flange, namely water flow discharged by the notch of the two water drainage grooves can be blocked by the water diversion flange as long as the water flows along the outer end face of the outer baffle plate, then the water flow is guided to a region far away from the air inlet, and the possibility that fresh air flow is brought into a fresh air pipe is reduced.

In a preferred technical scheme, the water diversion flange is positioned at the lower edge of the outer baffle.

By arranging the water diversion flange at the lower edge of the outer baffle, rainwater received by the outer baffle in all height directions and flowing downwards along the outer end face of the outer baffle can be guided to a position far away from the air inlet, namely a position with low wind speed, so that the possibility that the part of rainwater is sucked is remarkably reduced.

In a preferred technical solution, the lower grille further comprises an axial grille, and the axial grille intersects with the circumferential grille; along the axial direction of the fresh air pipe rain cover, the circumferential position of the axial grille on one side of the circumferential grille is different from the circumferential position of the axial grille on the other side of the circumferential grille.

By arranging the axial grids, rainwater on the axial grids continuously flows for a long time on the axial grids arranged along the bus direction in the area of the circumferential grids without the water retaining ribs can be avoided. Since, in general, the circumferential grating is at a larger angle in most, if not most, areas than the axial grating, when rainwater flows over the axial grating, it encounters the circumferential grating, and then does not continue to flow along the axial grating, but along the encountered circumferential grating until it drips from the lowest point of the circumferential grating. Therefore, the time for attaching rainwater on the surface of the lower grille can be reduced, and the possibility that the rainwater is sucked by fresh air flow is reduced.

The second object of the present utility model is to provide an air conditioner, which solves the technical problem that the rain-proof cover of the fresh air duct is easy to be brought into the fresh air duct by the fresh air flow.

The air conditioner provided by the utility model comprises a fresh air fan, wherein the fresh air fan comprises a fresh air pipe, the fresh air pipe is provided with an outdoor section, and the outdoor section is provided with any one of the fresh air pipe rainproof cover.

By arranging the fresh air pipe rainproof cover in the air conditioner, the air conditioner has all the advantages of the fresh air pipe rainproof cover, and the description is omitted herein.

Detailed Description

In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

Embodiment one:

fig. 2 is a schematic structural diagram of a rain cover for a fresh air duct according to an embodiment of the present utility model; fig. 3 is a schematic structural view of a rain cover for a fresh air duct according to an embodiment of the present utility model after being inverted. As shown in fig. 2-3, the first embodiment of the present utility model provides a fresh air duct rain shield, which includes an upper cover body 10 and a lower grille 20, wherein the lower grille 20 includes a circumferential grille 21, two ends of the circumferential grille 21 are connected to a lower edge of the upper cover body 10, and a water blocking rib 23 extending along a length direction of the circumferential grille 21 and protruding downward is provided on an outer surface of a part of the circumferential grille 21 near one side of an inner end of the fresh air duct rain shield.

In general, the axial direction of the fresh air pipe rain cover refers to the length direction of the fresh air pipe, and the cross section of the fresh air pipe rain cover perpendicular to the axial direction is usually circular, elliptical or rectangular. Therefore, the circumferential direction of the fresh air pipe rain cover refers to the direction in which the edge of the section is located when the fresh air pipe rain cover is cut off along the section perpendicular to the axial direction. That is, the circumferential grill 21 is substantially perpendicular to the axial direction of the fresh air duct. The lower edge of the upper case 10 is at the lower end of a semicircular, semi-elliptical, or semi-rectangular pattern in a cross section perpendicular to the axis of the upper case 10.

Wherein, the inner end near the rain shield of the fresh air pipe refers to one or more circumferential grids 21 which are closer to the inner end of the rain shield of the fresh air pipe than the other circumferential grids 21 along the axial direction of the rain shield of the fresh air pipe. And the spaces between the plurality of circumferential gratings 21 may form the air inlets of the fresh air duct rain cover.

Through setting up manger plate protruding muscle 23, can make the water droplet when flowing along circumference grid 21, can flow gradually to bellied manger plate protruding muscle 23 down on, and then increase the distance between water droplet position and the air intake, and the farther from the air intake, its wind speed is less more, fresh air stream is wrapped up in and is blocked up the water on the circumference grid 21 and get into the weaker ability in the fresh air pipe rain-proof cover, so, can reduce the suction that water on the circumference grid 21 received, and then reduce the possibility that water on the circumference grid 21 got into the fresh air pipe rain-proof cover. In addition, since the water blocking ribs 23 are provided on the outer surface of the circumferential grill 21, even if the rainwater hanging on the axial end surfaces of the water blocking ribs 23 is upwardly moved by the upward suction force, the upward movement distance increases, the difficulty of bringing in the fresh air in which the water is finally upwardly sucked is increased, and thus the possibility of the rainwater being sucked into the fresh air duct can be reduced.

As shown in fig. 2 and 3, the water deflector ribs 23 preferably extend from one end to the other end of the circumferential grill 21.

The two ends of the circumferential grill 21 refer to the two ends of the circumferential grill 21 connected to the upper housing 10. Specifically, in the present embodiment, the water blocking ribs 23 extend continuously on the outer surface of the circumferential grill 21.

The water blocking ribs 23 extend from one end of the circumferential grille 21 to the other end, so that the outer surface of the circumferential grille 21 can be fully covered in the circumferential angle, and rainwater can flow to the water blocking ribs 23 no matter in any circumferential position when flowing along the circumferential grille 21 provided with the water blocking ribs 23, thereby reducing the possibility that the rainwater on the circumferential grille 21 is sucked by fresh air.

As shown in fig. 2 and 3, the water blocking ribs 23 preferably have a smaller dimension in the axial direction of the fresh air duct weather hood than the circumferential grille 21.

Specifically, in this embodiment, in the axial direction of the rain cover for the fresh air duct, the circumferential grille 21 has exposed outer surfaces on the outer sides of both end surfaces of the water blocking ribs 23, and each end surface of the water blocking ribs 23 has a width of 0.5mm to 2mm from the edge of the outer surface of the circumferential grille 21. When the rainwater is on the outer surface of the part of the circumferential grille 21, the rainwater can be contacted with the end surface of the water retaining rib 23 as long as the rainwater can be converged into water drops, and the end surface of the water retaining rib 23 is vertical to the horizontal plane or forms a very large acute angle with the horizontal plane, such as an acute angle larger than 80 degrees. When the water droplets come into contact with the end surfaces of the water blocking ribs 23, they immediately flow along the end surfaces of the water blocking ribs 23, instead of along the outer circumferential surface of the circumferential grill 21. Thus, the possibility of rainwater flowing along the water blocking ribs 23 is improved, and the possibility of rainwater being sucked is reduced.

Moreover, since the water blocking rib 23 is thinner than the circumferential grill 21, when rainwater flows to the outer circumferential surface of the water blocking rib 23, it is smaller than the circumferential grill 21, so that it is possible to more quickly collect water droplets and drop them down rapidly, thereby shortening the residence time thereof on the surface of the water blocking rib 23 and further reducing the possibility of being brought into a new duct by the intake air flow.

In a further implementation, the water deflector ribs 23 may also be of equal thickness to the circumferential grille 21, for example, a part of the circumferential grille 21 near the inside of the new air duct rain cover being of a larger radial dimension than the remaining circumferential grille 21. The part protruding outwards can be a water retaining convex rib 23

As shown in fig. 2 and 3, the number of the water blocking ribs 23 is preferably 1 to 10, and the water blocking ribs 23 are distributed on adjacent circumferential grids 21.

Wherein, the water blocking ribs 23 are distributed in adjacent circumferential grids 21, which means that the water blocking ribs 23 are arranged on a plurality of circumferential grids 21 closest to the inner side of the rain cover of the fresh air pipe, and the circumferential grids 21 without the water blocking ribs 23 are not mixed in the plurality of circumferential grids 21. As shown in fig. 4, the air flow velocity between the circumferential grids 21 which are closer to the inner end of the rain cover of the fresh air pipe is higher, so that only the important prevention of the rainwater on the circumferential grids 21 from being brought into the fresh air pipe by the fresh air flow is needed, and the total rainwater amount of the brought fresh air pipe can be obviously reduced. As shown in fig. 3, the number of the circumferential grids provided with the water blocking ribs 23 is six, and correspondingly, the number of the water blocking ribs 23 is six.

By selecting the number of the water retaining ribs 23 to be in the above range, the water retaining ribs 23 can be concentrated at a plurality of circumferential grids 21 with larger wind power of the fresh air pipe rain cover, so that the utilization rate of the water retaining ribs 23 is improved. As for several circumferential gratings 21 farther from the inner end of the rain cover of the fresh air duct, the water blocking ribs 23 are not required due to the small wind speed.

Preferably, the height of the water deflector ribs 23 is less than 10mm.

The height of the water blocking rib 23 refers to a difference in dimension of the outer peripheral surface of the fresh air duct in the radial direction of the rain cover with respect to the outer peripheral surface of the circumferential grill 21 provided with the water blocking rib 23 in the same direction.

The height of the water retaining ribs 23 is selected to be in the range, so that the distance between water drops flowing on the surface of the water retaining ribs 23 and the air inlet can be increased, and the possibility that rainwater is sucked is reduced. Moreover, when the height of the water blocking rib 23 is further increased, the improvement effect of preventing the rainwater from being sucked is not obvious, so that the material required for manufacturing the fresh air pipe rain cover can be saved by setting the height above.

As shown in fig. 5, preferably, the fresh air duct rain cover further includes an outer baffle 30, the outer baffle 30 is located at an axially outermost end of the fresh air duct rain cover, an outer end surface of the outer baffle 30 is provided with a water diversion flange 31, and the water diversion flange 31 protrudes in a direction away from the outer baffle 30.

Specifically, in this embodiment, the outer baffle 30 may be substantially circular, thereby blocking the end face of the fresh air duct rain cover.

The fact that the water diversion flange 31 protrudes in the direction away from the outer baffle 30 does not only mean that the water diversion flange 31 protrudes in the approximately horizontal direction in this embodiment, but in fact, the water diversion flange 31 may also protrude in an obliquely upward or downward direction, so long as the protruding direction of the water diversion flange 31 has a component in the protruding direction along the axial direction of the fresh air duct rain cover, the effect of guiding rainwater to the area with a larger air intake speed away from the fresh air duct rain cover can also be achieved.

By providing the outer baffle 30, it is possible to prevent rainwater from being affected by wind force to fall obliquely to the region between the lower grill 20 and the upper housing 10, and to be brought into the fresh air duct by the fresh air flow entering the fresh air duct. Moreover, the water flow on the outer end surface of the outer baffle 30 can be blocked from flowing all the way to the lower edge of the outer baffle 30 by the water diversion flange 31 and overhang the lower edge to be influenced by wind force of the inlet air. The water diversion flange 31 is protruded along the direction, so that when water drops or water flows leave the water diversion flange 31, the distance between the water drops or the water flows and the inner side surface of the outer baffle 30 is increased, the falling wind speed is obviously reduced, and the possibility that the water drops or the water flows are sucked by fresh air flow is also reduced.

As shown in fig. 5, preferably, the lower edge of the upper casing 10 is provided with a drain groove 11, the drain groove 11 extending from one end of the upper casing 10 to the other end of the upper casing 10, the outer end of the drain groove 11 being open and being lower than the inner end of the drain groove 11; the outer baffle 30 adjoins the bottom of the drainage channels 11, the outer ends of the two drainage channels 11 being located between the ends of the water-guiding flanges 31.

By providing the drainage groove 11 with an opening at the outer end, the drainage groove 11 is located at two lower edges of the upper cover 10 in the circumferential direction, so that after rainwater hits the upper cover 10, the rainwater flows downwards along the surface of the upper cover 10, flows into the drainage groove 11, and flows to the opening of the drainage groove 11 through the drainage groove 11, in addition to the water drops which are splashed and ejected. When the water flow leaves the water discharge groove 11, except that the water flow can flow downwards along the parabola when the water flow in the water discharge groove 11 is large, as the outer baffle plate 30 positioned at the axially outermost end of the fresh air pipe rain cover is adjacent to the bottom of the water discharge groove 11, when the water flow in the water discharge groove 11 is small, the water flow which leaves the bottom of the water discharge groove 11 can continue to flow along the outer surface of the outer baffle plate 30 or the edge of the outer baffle plate 30, and the water flow is not easily brought into the fresh air pipe by the fresh air flow as if the water flow is directly hung on a lower edge of a certain level or close to the level.

The water diversion flange 31 is arranged, and the outer ends of the two water diversion grooves 11 are positioned between the two ends of the water diversion flange 31, namely, the water flow discharged by the notch of the two water diversion grooves 11 can be blocked by the water diversion flange 31 as long as the water flow flows along the outer end face of the outer baffle 30, and then the water flow is guided to a region far away from the air inlet, so that the possibility that the fresh air flow is brought into the fresh air pipe is reduced.

As shown in fig. 5, the water diversion flange 31 is preferably located at the lower edge of the outer baffle 30.

Specifically, in the present embodiment, the water diversion flange 31 may be substantially semicircular with an upward opening, and located at the edge position of the lower semicircle of the substantially circular outer baffle 30. More specifically, the water diversion flange 31 may correspond to a central angle of 180 °, and both ends of the water diversion flange 31 are at the same height as the center of the outer baffle 30.

By providing the water diversion flange 31 at the lower edge of the outer baffle 30, rainwater received by the outer baffle 30 in all height directions and flowing downwards along the outer end surface of the outer baffle 30 can be guided to a position far from the air inlet, namely a position with low wind speed, so that the possibility that part of rainwater is sucked is remarkably reduced.

As shown in fig. 2 and 3, the lower grille 20 preferably further comprises an axial grille 22, the axial grille 22 intersecting the circumferential grille 21; the circumferential position of the axial grille 22 on one side of the circumferential grille 21 is different from the circumferential position of the axial grille 22 on the other side of the circumferential grille 21 in the axial direction of the fresh air duct rain cover.

Specifically, in this embodiment, it is meant that the axial grill 22 on one side of a certain one of the circumferential grilles 21 is located at a position directly below in a cross section perpendicular to the axial direction of the fresh air duct rain cover, and the axial grill 22 on the other side of the certain one of the circumferential grilles 21 is located at a position deviated from directly below in the same cross section. Still further, the axial grids 22 at different circumferential positions are located at positions that can be spaced apart, i.e., such that the axial grids 22 between the second three, fourth five, and sixth seven … … axially from the outer baffle 30 are at the lowermost position in the above-mentioned cross section, and the axial grids 22 between the first two, third four, and fifth six … … are all at positions rotated by 80 ° from the horizontal direction in the counterclockwise direction in the above-mentioned cross section.

The provision of the axial louver 22 in this way can prevent rainwater on the axial louver 22 from continuously flowing on one axial louver 22 provided in the direction of the generatrix for a longer period of time in the region of the circumferential louver 21 where the water blocking ribs 23 are not provided. Since, in general, the circumferential grating 21 is at a larger angle than the axial grating 22 in most, if not most, areas, when rainwater flows over the axial grating 22, it encounters the circumferential grating 21, and does not continue to flow along the axial grating 22, but flows along the encountered circumferential grating 21 until it drips from the lowest point of the circumferential grating 21. Therefore, the time for rainwater to adhere to the surface of the lower grill 20 can be reduced, and the possibility of the rainwater being sucked by the fresh air flow can be reduced.
