Description

Air purifier

Technical Field

The present invention relates to an air cleaner, and more particularly, to an air cleaner capable of placing objects thereon.

Background

An air cleaner is a device that purifies sucked indoor air and supplies the purified air into a room.

The air purifier includes: a fan sucking indoor air into the housing; and a filter for filtering foreign matters contained in the air sucked by the fan.

Air purifiers generally provide a discharge port at an upper portion to supply purified air to a remote location of an indoor space. In contrast, the air purified in the air cleaner case is discharged upward by the fan and is diffused into the indoor space.

In recent years, there has been an increasing demand for air purifiers having functions other than air purification. As an example, in recent years, users who can place objects in a space where an air cleaner is disposed are expected to increase.

However, since the conventional air cleaner discharges the purified air upward, there is a problem in that it is difficult to use the upper portion of the air cleaner as a space for placing objects.

In addition, since the conventional air cleaner discharges purified air upward, there is a problem in that the discharged air cannot reach a user and spread to a position far from the user. In this case, when the position of the discharge port is changed in order to supply purified air to the user, there is a problem in that the discharged air flows in again from the suction port.

The second body 100 may include a lamp 151. The lamp 151 may receive light from the light guide 150. The lamp 151 may be exposed at the underside of the lower wall 102. The lamp 151 may radiate light transmitted through the light guide 150 to the lower side of the lower wall 102. The lamp 151 may have a ring shape. The lamp 151 may be located radially outward of the lower body 110. The lamp 151 may be farther from the lower body 110 than the bonding apparatus key 141.

The second body 100 may include a first key 171. The second body 100 may include a second key 172. The second body 100 may include a third key 173. The first to third keys 171, 172, 173 may be connected with the key assembly 170. The first to third keys 171, 172, 173 may be exposed at the lower side of the lower wall 102. The first to third keys 171, 172, 173 may each have a shape different from each other. A portion of the first to third keys 171, 172, 173 may protrude toward the lower side of the lower wall 102. A portion of the first to third keys 171, 172, 173 may be recessed toward the upper side of the lower wall 102. The user can adjust the driving of the air cleaner 1 including the fan 17 by operating the first to third keys 171, 172, 173 exposed at the lower side of the lower wall 102. The keys 171, 172, 173 may be located radially outward of the lower body 110. The keys 171, 172, 173 may be farther from the lower body 110 than the bonding apparatus keys 141. The keys 171, 172, 173 may be located closer to the edge 103 than the lower body 110.

The air purifier 1 will be described with reference to fig. 6.

Fig. 6 is a cross-sectional view of the second body 100 cut in a vertical direction.

The lower body 110 may be located at a central portion of the second body 100. The second body 100 may have a symmetrical shape about the lower body 110.

The coupling device 140 may be located inside the outer circumferential surface 111 of the lower body 110. A portion of the coupling device 140 may protrude outward of the outer circumferential surface 111.

The coupling device key 141 may be located radially outward of the outer circumferential surface 111 of the lower body 110. The bonding means key 141 may be exposed at the underside of the lower wall 102.

The lamp 151 may be located radially outward of the outer circumferential surface 111 of the lower body 110. The lamp 151 may be located further outside the second body 100 than the bonding apparatus key 141.

The first key 171 may protrude toward the lower side of the lower wall 102. The first key 171 may be formed to protrude toward the lower side of the bottom surface of the lower wall 102. The first key 171 may be located between the bonding means key 141 and the edge 103. The first key 171 may induce a Coanda Effect (Coanda Effect) on air flowing along the lower wall 102. The direction of flow of air flowing along the lower wall 102 may be directed towards the edge 103 by the first keys 171.

The air discharged through the discharge port 12 (see fig. 3) can flow upward along the outer peripheral surface 111, and then the flow direction is guided by the lower wall 102. Air flowing along the lower wall 102 is directed by the combination of the device keys 141 and keys 171, 172, 173 towards the edge 103.

The air purifier 1 will be described with reference to fig. 7.

Fig. 7 is a part of a sectional view of the air cleaner 1 cut in the vertical direction.

The cover 18 may be spaced from the inside of the peripheral wall 15. Discharge flow paths 12a, 12b toward the discharge port 12 may be formed between the outer peripheral wall 15 and the cover 18. The discharge flow paths 12a and 12b may be formed so that the width thereof increases toward the upper side. The width G1 of the first discharge flow path 12a may be smaller than the width G2 of the second discharge flow path 12b.

The bracket 19 may include a bracket outer wall 19a. The bracket outer wall 19a may be spaced apart from the inner side of the outer peripheral wall 15. The second discharge flow path 12b may be formed between the tray outer wall 19a and the outer peripheral wall 15. A space into which the lower body 110 is inserted may be formed inside the bracket outer wall 19a. The second body 100 may be inserted into and fixed to the inner space of the bracket outer wall 19a. The bracket outer wall 19a and the outer peripheral surface 111 of the lower body 110 may form a continuous surface. The bracket outer wall 19a may be located at an upper side of the cover 18.

The air blown by the fan 17 (see fig. 3) can flow upward between the outer peripheral wall 15 and the cover 18. At this time, the width of the discharge flow paths 12a, 12b may be larger as it is more upward. The air flowing upward toward the discharge port 12 can flow upward along the cover 18 and the tray outer wall 19a. The air discharged to the discharge space S through the discharge port 12 can flow along the discharge grid 14 toward the outer peripheral surface 111 of the lower body 110. The air flowing along the discharge grill 14 can be guided upward by the outer peripheral surface 111. The air discharged into the discharge space S can flow along the lower wall 102 from the boundary portion 101. The air flowing along the lower wall 102 may flow upward along the slope of the lower wall 102. At this time, by the shapes of the coupling device keys 141 and 171 formed on the lower wall 102, vortex formation is suppressed, and the straight-ahead property of the air flow can be improved.

The edge 103 may be located further outside than the outer peripheral wall 15 of the first body 10. A space D may be formed between the edge 103 and the peripheral wall 15. The suction port 11 (see fig. 1) may be formed along the periphery of the peripheral wall 15. Thus, the edge 103 is located further outside than the outer peripheral wall 15, so that the air flowing along the lower wall 102 can be prevented from flowing again from the suction port 11.

The angle θ1 by which the lower wall 102 is inclined with respect to the horizontal direction may be 30 degrees to 35 degrees.

The more the lower wall 102 may be inclined with respect to the horizontal direction, the greater the outer side of the second body 100. The angle θ3 by which the lower wall 102 is inclined at the boundary portion 101 may be smaller than the angle θ4 by which the lower wall 102 is inclined at the edge 103. The angle at which the lower wall 102 is inclined with respect to the horizontal direction may become larger as approaching the edge 103 from the boundary portion 101.

The lower wall 102 may include: a first lower wall 102a vertically opposed to the discharge port 12; and a second lower wall 102b extending from the first lower wall 102a to the outside of the second body 100. The discharge space S may be formed between the first lower wall 102a and the discharge grid 14. The second lower wall 102b may be located further outside than the outer wall 15 of the first body 10.

The bottom surface of the lower wall 102 may be formed by bending. The bottom surface of the first lower wall 102a may be curved and extended toward the upper side. The bottom surface of the second lower wall 102b may be curved and extended toward the upper side.

The radius of curvature of the bottom surface of the lower wall 102 may be smaller toward the outside of the second body 100. The bottom surface of the lower wall 102 may be curved upward as it tends to the outer side of the second body 100. The radius of curvature R1 of the first lower wall 102a may be greater than the radius of curvature R2 of the second lower wall 102 b.

Hereinafter, a second body 1000 according to another embodiment of the present invention will be described with reference to fig. 8 to 11.

Fig. 8 is a perspective view of the second body 1000. Fig. 9 is a view of the second body 1000 from the lower side. Fig. 10 is a cross-sectional view of the second body 1000 cut in a vertical direction. Fig. 11 is a part of a sectional view of the air cleaner to which the second body 1000 is mounted.

The second body 100 described with reference to fig. 1 to 7 or the second body 1000 described with reference to fig. 8 to 11 may be selectively attached to and detached from the first body 10 (see fig. 1). The second body 100 described with reference to fig. 1 to 7 is detachable from the bracket 19. The second body 1000 described with reference to fig. 8 to 11 can be attached to and detached from the bracket 19 in the same manner. That is, the second body 100 of the first embodiment and 1000 of the second embodiment may be compatible with the first body 10.

The description of the second body 100 described with reference to fig. 1 to 7 may be equally applicable to the second body 1000 described with reference to fig. 8 to 11.

The second body 1000 may include a lower body 1100. The lower body 1100 may be combined with the first body 10 (refer to fig. 1). The lower body 1100 may be cylindrical in shape. The lower body 1100 may have the same structure as the lower body 110 of fig. 1 to 7.

The second body 1000 may include an upper body 1200. The upper body 1200 may be disposed at an upper side of the lower body 1100. The length L1 of the upper body 1200 in the first direction may be greater than the length L2 in the second direction. The shape of the horizontal cross section of the upper body 1200 may be elliptical. That is, unlike the upper body 120 of the first embodiment, which has a circular cross-sectional shape, the cross-sectional shape of the upper body 1200 of the second embodiment may be elliptical. The cross-sectional area of the upper body 1200 of the second embodiment may be larger than that of the upper body 120 of the first embodiment.

The description of the upper body 120 described with reference to fig. 1 to 7 may be equally applicable to the upper body 1200 of the second embodiment, except for the differences in the above-described shapes.

The second body 1000 may include a top cover 1300. The top cover 1300 may be disposed at an upper side of the upper body 1200. The length L1 of the top cover 1300 in the first direction may be greater than the length L2 in the second direction. The shape of the horizontal cross section of the top cover 1300 may be elliptical. That is, unlike the top cover 130 of the first embodiment, which has a circular cross-sectional shape, the cross-sectional shape of the top cover 1300 of the second embodiment may be elliptical. The cross-sectional area of the top cover 1300 of the second embodiment may be larger than that of the top cover 130 of the first embodiment.

The description of the top cover 130 described with reference to fig. 1 to 7 may be equally applicable to the top cover 1300 of the second embodiment, except for the differences in the shape described above.

Referring to fig. 9, a second body 1000 according to another embodiment of the present invention will be described.

The second body 1000 may include a lower body 1100 in a cylindrical shape. The lower body 1100 may have a cylindrical outer circumferential surface 1110.

The second body 1000 may include an inclined lower wall 1002. The second body 1000 may include an edge 1003.

The second body 1000 may include a bonding device key 1410. The bonding device key 1410 may be exposed to the underside of the lower wall 1002.

The second body 1000 may include a lamp 1510. The lamp 1510 may be exposed to the underside of the lower wall 1002.

The second body 1000 may include keys 1710, 1720, 1730. The buttons 1710, 1720, 1730 may be located closer to the edge 1003 than the outer peripheral surface 1110. The keys 1710, 1720, 1730 may be located farther from the lower body 1100 than the bonding device key 1410.

The bonding device key 1410 and keys 1710, 1720, 1730 may be located on the long axis of the upper body 1200. The cross section of the upper body 1200 may be oval, and the combination device keys 1410 and the keys 1710, 1720, 1730 may be aligned along the long axis of the upper body 1200.

The second body 1000 will be described with reference to fig. 10 and 11.

The second body 1000 may include a coupling device 1400, a coupling device key 1410, a lamp 1510, a key assembly 1700, and a key 1710. The description of the structures 140, 141, 151, 170, 171 described with reference to fig. 1 to 7 applies equally to the structures 1400, 1410, 1510, 1700, 1710 described above.

The bonding device key 1410, the lamp 1510, and the key 1710 may be arranged along a direction in which the lower wall 1002 extends. The bonding device key 1410, light 1510, and key 1710 may be exposed on the underside of the lower wall 1002.

The bonding device key 1410, the lamp 1510, and the key 1710 may be arranged in this order on the lower wall 1002 extending from the outer peripheral surface 1110 of the lower body 1100 to the rim 1003.

The air blown from the fan 17 (see fig. 3) may be discharged to the discharge space S along the discharge flow paths 12a and 12b, and then may flow obliquely upward along the lower wall 1002. As for the flow direction of the air blown by the fan 17 (refer to fig. 3), the same description with reference to fig. 1 to 7 can be used.

The edge 1003 of the second body 1000 may be located further outside than the outer peripheral wall 15 of the first body 10. A space D2 may be formed between the edge 1003 and the peripheral wall 15. The interval D2 between the edge 1003 and the peripheral wall 15 in the second embodiment may be larger than the interval D between the edge 103 and the peripheral wall 15 in the first embodiment (refer to fig. 7). In contrast, the second embodiment may have a greater distance along the lower wall 1002 for the air discharged to the discharge space S than the first embodiment.

The lower wall 1002 may be inclined upward as it tends to the outside of the air cleaner 1. The more the inclination angle of the lower wall 1002 may be toward the outside of the air cleaner 1. As an example, the tilt angle θ3 between the lower body 1100 and the bonding device key 1410 may be smaller than the tilt angle θ4 between the key 1710 and the bonding device key 1410. Thus, the occurrence of vortex due to the relatively longer length of the lower wall 1002 compared with the first embodiment can be suppressed.

The effect of the air cleaner 1 will be described with reference to fig. 12.

Fig. 12 (a) is a diagram showing the direction of the air flow discharged from the air cleaner 1. Fig. 12 (b) is a diagram for explaining a case where the air cleaner 1 is provided in the vicinity of the bed Bd. Fig. 12 (c) is a view for explaining a case where the air cleaner 1 is provided in the vicinity of the sofa Sf.

The air cleaner 1 may have a height H1 in the up-down direction. The height H1 from the lower end to the upper end of the air cleaner 1 may be in the range of 50cm to 60 cm.

The discharge port 12 (see fig. 1) of the air cleaner 1 may be spaced a predetermined distance H2 upward from the floor surface. The distance H2 separating the discharge opening 12 from the ground may be in the range of 35cm to 45 cm.

The maximum elevation H3 of the air discharged from the air cleaner 1 may be within a range of 115cm to 125 cm.

The air discharged from the air cleaner 1 may have an upward inclination angle a. The inclination angle a of the air discharged from the air cleaner 1 may be in the range of 30 degrees to 35 degrees with respect to the horizontal direction.

The lower wall 102, 1002 of the second body 100, 1000 may extend obliquely upward. The inclination angle of the lower wall 102, 1002 may be in the range of 30 degrees to 35 degrees (refer to fig. 7 and 11). The lower walls 102 and 1002 are formed obliquely, so that the air discharged from the air cleaner 1 may have an upward inclination angle a. Since the air discharged from the air cleaner 1 has the upward inclination angle a, the purified air is not directly transmitted to the user, but can be supplied to the vicinity of the user. Thus, since the air flow of the purified air is not directly transferred to the user but supplied to the vicinity of the user, the user can feel more comfortable than when the air flow is directly transferred to the user.

The height at which the user's head contacts the bed Bd may be spaced a prescribed distance HB from the ground. The height HB of the user's head in contact with the bed Bd may be 53.7cm on average.

The user sits at the height of the sofa Sf at a prescribed distance HS1 from the ground. The height HS1 at which the user sits on the sofa Sf may be 40.9cm on average.

The armrests in the sofa Sf may be located at a specified distance HS2 from the ground. The height HS2 at which the armrests in the sofa Sf may be 55.3cm on average.

Thus, when the air cleaner 1 of the present invention is disposed in the vicinity of the bed Bd or the sofa Sf as the air cleaner having the height from the floor discharge port 12 within the predetermined range, the discharged air has the predetermined inclination angle a, and therefore, the flow of the discharged air can be prevented from being directly transmitted to the user.
