Description

Technical Field

[0001] The invention relates to a filter assembly and an air purifier comprising the filter assembly. Background Art

[0002] Generally speaking, an air purifier is a device that inhales polluted indoor air and removes dust, odor particles, etc. contained in the air through a filter to purify it into clean air. This air purifier can purify indoor air by inhaling polluted air around it, purifying it, and then discharging the purified air to the outside of the air purifier.

[0003] In addition, the air purifier may include a filter for removing dust, odor particles, etc. contained in the air flowing into the interior, and a frame on which the filter can be replaceably mounted. In addition, the filter configured inside the air purifier may provide a plurality of various filters having different functions from each other, such as a high-efficiency air filter, a deodorizing filter, a functional filter, etc.

[0004] The applicant's Korean Patent Publication No. 10-2016-0099145 “Air Purifier” (Patent Document 1) discloses a frame supporting a first air purification filter, a second air purification filter, a functional filter, and a filter for filtering air.

[0005] However, since the multiple filters are individually mounted on the frame, the air purifier of Patent Document 1 is difficult to replace the multiple filters. For example, in order to replace the multiple filters, the staff needs to separate the multiple filters from the frame and reinstall the multiple filters on the frame. In this case, it takes a long time to operate, and it is difficult for the staff to separate and install the multiple filters individually. In addition, there is the inconvenience that the staff must transport the multiple filters for filter replacement.

[0006] Therefore, there is a need for an air purifier including a filter assembly, which can mount or detach various types of filters on a frame at one time and is easy to transport.

[0007] In addition, the applicant's Korean Patent Publication No. 10-2018-0138247 "Air Purifier with Bidirectional Fans with Different Exhaust Directions" (Patent Document 2) has an upper bidirectional fan and a lower bidirectional fan that can flow air.

[0008] However, since the upper bidirectional fan and the lower bidirectional fan of the air purifier of Patent Document 2 operate at the same speed, when multiple filters of different types are arranged in the vertical direction, the filter arranged at the upper part and the filter arranged at the lower part may have different pressure differences. For example, when the filter arranged at the lower part is an activated carbon filter and the filter arranged at the upper part is a filter with a mesh structure, even if the upper bidirectional fan and the lower bidirectional fan operate in the same manner, the filter arranged at the upper part and the filter arranged at the lower part may have different pressure differences. In this case, only the upper filter will quickly reach the replacement cycle, and there is a problem of low purification efficiency of the air purifier.

[0009] In addition, in the air purifier of Patent Document 2, the air passing through the filter flows to both the upper two-way fan and the lower two-way fan, so that a vortex is generated between the filter and the fan. In addition, the air does not flow to the fan immediately after passing through the filter, but stays in the space between the filter and the fan, thereby prolonging the flow time of the air. In this case, there is a problem of low purification efficiency of the air purifier.

[0010] Therefore, there is a need for an air purifier that can control multiple fans so that even if multiple filters are configured, only any one filter will not reach the replacement cycle quickly.

[0011] In addition, a filter assembly and an air purifier including the filter assembly are needed, which can prevent vortexes from being generated between the filter and the fan and can improve the purification efficiency of the air purifier. Summary of the invention

[0059] In addition, it should be noted in advance that in this specification, the description of the up and down directions is based on the drawings, and will be expressed differently when the direction of the corresponding object changes. In addition, the up and down directions, left and right directions, and front and back directions in this specification may be the directions of the coordinate axes of the drawings.

[0060] Hereinafter, with reference to the accompanying drawings, the specific structure of the air purifier 1 according to an embodiment of the present invention will be described.

[0061] Reference Figure 1 and Figure 2The air purifier 1 according to the first embodiment of the present invention can purify polluted air into clean air by filtering dust, odor particles, etc. in the air flowing into the air purifier 1. In addition, the air purifier 1 can suck the external air into the interior, and can discharge the clean air purified inside to the outside. Such an air purifier 1 may include a frame 100, a filter assembly 200, a fan assembly 300, a control device 400, and a pre-filter 500.

[0062] The frame 100 may support the filter assembly 200 and the fan assembly 300. In addition, the frame 100 may support the filter assembly 200 so that the filter assembly 200 can be replaceably installed. Such a frame 100 may include a body frame 110, a cover frame 120, and a support frame 130.

[0063] The main frame 110 may support the filter assembly 200 and the fan assembly 300. For example, a predetermined space may be formed inside the main frame 110, and the filter assembly 200 and the fan assembly 300 disposed inside may be supported. Such a main frame 110 may be provided with an exhaust port 111, and the exhaust port 111 is used to exhaust the air flowing into the inside of the frame 100 to the outside of the frame 100. Such an exhaust port 111 may be formed on the upper surface of the main frame 110.

[0064] The cover frame 120 may be detachably combined with the main frame 110. Such a cover frame 120 may cover both side surfaces in the front-rear direction of the main frame 110. In addition, an inlet 121 may be provided on the cover frame 120 for allowing air outside the frame 100 to flow into the inside of the frame 100.

[0065] In addition, a plurality of cover frames 120 may be provided, and the plurality of cover frames 120 may be combined with both sides of the main frame 110. For example, the plurality of cover frames 120 may be combined with the front and rear surfaces of the frame 100. In this case, external air may flow in from both sides of the front and rear of the frame 100.

[0066] Reference Figure 2 and Figure 3 The support frame 130 can support the filter assembly 200, and the filter assembly 200 can be detachably mounted to the support frame 130. In addition, the support frame 130 can be arranged inside the main frame 110, and can be arranged on both sides in the front and rear directions based on the fan assembly 300. Such a support frame 130 may include a first support portion 131, a second support portion 132, a protruding rib 133, and a frame flange 134.

[0067] When the filter assembly 200 is mounted on the frame 100, the first support portion 131 can support the outer peripheral surface of the filter holder 210. For example, when the filter assembly 200 is mounted on the frame 100, the first support portion 131 can support the upper surface, lower surface, left side surface, and right side surface of the edge portions 211 and 212 to be described later.

[0068] When the filter assembly 200 is mounted on the frame 100, the second support portion 132 may support at least a portion of the filter holder 210. For example, when the filter assembly 200 is mounted on the frame 100, the second support portion 132 may support an edge of the first edge portion 211 to be described later. Such a second support portion 132 may extend from a fan housing 320 to be described later toward the outside of the frame 100.

[0069] The protruding ribs 133 can support the partition 213 of the filter holder 210, which will be described later. For example, a plurality of protruding ribs 133 can be provided, and when the filter assembly 200 is installed on the frame 100, the plurality of protruding ribs 133 can support the plurality of wall portions 213a, which will be described later. In this case, the plurality of protruding ribs 133 can be close to the plurality of wall portions 213a, and can form a flow path of air together with the plurality of wall portions 213a. In addition, when the filter assembly 200 is installed on the frame 100, the plurality of protruding ribs 133 protrude in a manner facing the plurality of wall portions 213a. However, this is only an example, and the protruding ribs 133 can protrude toward the groove between the wall portions 213a, or can also protrude toward the first filter area 210a and the second filter area 210b.

[0070] When the filter assembly 200 is mounted on the frame 100, the frame flange 134 can prevent the filter assembly 200 from being excessively inserted into the inner side of the frame 100. For example, when the filter assembly 200 is mounted on the frame 100, the filter assembly 200 may be stuck on the frame flange 134. In this case, the filter assembly 200 is not closely attached to the fan housing 320 and may be spaced apart from the fan housing 320. Such a frame flange 134 may be formed on at least one of the first support portion 131 and the second support portion 132.

[0071] Reference Figure 4 and Figure 5, the filter assembly 200 can filter the external air into clean air. Such a filter assembly 200 can be detachably mounted on the frame 100. For example, when the filter assembly 200 is used for a predetermined time, it can be replaced with a new filter assembly 200. In addition, a plurality of filter assemblies 200 can be provided, and the plurality of filter assemblies 200 can be arranged on both sides of the frame 100. For example, a plurality of filter assemblies 200 can be arranged on both sides of the front and rear of the frame 100. In this case, the plurality of filter assemblies 200 can filter the air flowing in from both sides of the front and rear of the frame 100. Such a filter assembly 200 may include a filter holder 210 and a filter portion 220.

[0072] The filter holder 210 may support the filter unit 220 and may be mounted on the frame 100. In addition, the filter holder 210 may be disposed in a manner of surrounding the filter unit 220. Such a filter holder 210 may have a first filter region 210a and a second filter region 210b.

[0073] The first filter member 221 and the second filter member 222 may be placed together in the first filter region 210a. In this case, in the first filter region 210a, the first filter member 221 and the second filter member 222 may be arranged along the thickness direction of the filter holder 210. Such a first filter region 210a may include a first main region 211a and a first sub-region 212a in which different kinds of filter members 221, 222, 223 are arranged.

[0074] The first filter element 221 may be disposed in the first main region 211a, and the second filter element 222 may be disposed in the first sub-region 212a. In addition, the first main region 211a and the first sub-region 212a may be arranged along the thickness direction of the filter holder 210. For example, when the filter assembly 200 is mounted on the frame 100, the first main region 211a may be placed in a manner that is more adjacent to the inner side of the frame 100 than the first sub-region 212a. In addition, referring to Figure 6 , a thickness T1 of the first main region 211 a in the front-to-back direction may be greater than a thickness T2 of the first sub-region 212 a in the front-to-back direction.

[0075] Re-reference Figure 4 and Figure 5, the first filter member 221 and the third filter member 223 may be placed together in the second filter region 210b. In this case, in the second filter region 210b, the first filter member 221 and the third filter member 223 may be arranged along the thickness direction of the filter holder 210. In addition, the pressure difference between the air before passing through the second filter region 210b and the air after passing through the second filter region 210b may be different from the pressure difference between the air before passing through the first filter region 210a and the air after passing through the first filter region 210a. For example, the pressure difference of the air caused by the second filter region 210b may be less than the pressure difference of the air caused by the first filter region 210a.

[0076] In addition, when the filter assembly 200 is mounted on the frame 100, the second filter area 210b may be placed on the upper side of the first filter area 210a. In addition, the second filter area 210b may include a second main area 211b and a second sub-area 212b configured with different kinds of filter members 221, 222, 223.

[0077] The first filter element 221 may be disposed in the second main region 211b, and the third filter element 223 may be disposed in the second sub-region 212b. In addition, the second main region 211b and the second sub-region 212b may be arranged along the thickness direction of the filter holder 210. For example, when the filter assembly 200 is mounted on the frame 100, the second main region 211b may be placed in a manner that is more adjacent to the inner side of the frame 100 than the first sub-region 212a. In addition, referring to Figure 6 , a thickness T1 of the second main region 211 b in the front-to-back direction may be greater than a thickness T2 of the second sub-region 212 b in the front-to-back direction.

[0078] Although the first filter area 210a and the second filter area 210b are described as having the main areas 211a and 211b and the sub-areas 212a and 212b, respectively, this is only an example and the present invention is not limited thereto. Therefore, at least one of the first filter area 210a and the second filter area 210b may include the main areas 211a and 211b and the sub-areas 212a and 212b. For example, only the first filter area 210a may include the main area 211a and the sub-area 212a.

[0079] In addition, the filter holder 210 may include a first edge portion 211 , a second edge portion 212 , a partition portion 213 , and a step 214 .

[0080] The first edge portion 211 surrounds the first filter member 221 and can support the first filter member 221. Such a first edge portion 211 can form at least a portion of the first filter region 210a and can form at least a portion of the second filter region 210b. For example, the first edge portion 211 can form a first main region 211a of the first filter region 210a and a second main region 211b of the second filter region 210b. In addition, when the filter assembly 200 is mounted on the frame 100, the first edge portion 211 can be supported on the first support portion 131 and the second support portion 132.

[0081] In addition, refer to Figure 7 , when viewed in the up-down direction, at least a portion of each of the two side ends of the first edge portion 211 in the left-right direction may have an inclined shape. For example, when viewed in the up-down direction in a state where the filter assembly 200 is mounted on the frame 100, the two side ends of the first edge portion 211 in the left-right direction may be farther away from each other as they are moved toward the outside of the frame 100. In this case, it is possible to prevent the filter assembly 200 from being mounted on the frame 100 in a manner such that the second edge portion 212 is disposed on the inner side of the frame 100 than the first edge portion 211. In other words, when the filter assembly 200 is mounted on the frame 100 in a manner such that the second edge portion 212 is disposed on the inner side of the frame 100 than the first edge portion 211, the two side ends of the first edge portion 211 in the left-right direction may be interfered with by the support frame 130.

[0082] In addition, refer to Figure 8 , when viewed in the left-right direction, one of the two side ends of the first edge portion 211 in the up-down direction has an inclined shape, and the other side end has an inclination different from that of the one side end. For example, when viewed in the left-right direction, the upper and lower side ends of the first edge portion 211 are inclined so that the upper side end and the lower side end have different inclinations. In this case, it is possible to prevent the filter assembly 200 from being installed on the frame 100 in a manner such that the first filter area 210a is placed on the upper side of the second filter area 210b. In other words, when the filter assembly 200 is installed on the frame 100 in a manner such that the first filter area 210a is placed on the upper side of the second filter area 210b, the two side ends of the first edge portion 211 in the up-down direction may be interfered with by the support frame 130.

[0083] The second edge portion 212 surrounds the second filter member 222 and the third filter member 223, and can support the second filter member 222 and the third filter member 223. Such second edge portion 212 can form at least a portion of the first filter region 210a, and can form at least a portion of the second filter region 210b. For example, the second edge portion 212 can form a first sub-region 212a of the first filter region 210a and a second sub-region 212b of the second filter region 210b. In addition, when the filter assembly 200 is mounted on the frame 100, the second edge portion 212 can be placed on the outer side of the frame 100 than the first edge portion 211.

[0084] Re-reference Figure 5 , the partition 213 can divide the first filter area 210a and the second filter area 210b. Such a partition 213 can be formed to cross the first edge portion 211 and the second edge portion 212 with a predetermined width and extend. In addition, the partition 213 can be integrated with the first edge portion 211 and the second edge portion 212. Such a partition 213 can have a predetermined height H in the up-down direction, and the height H of the partition 213 can be greater than at least one of the thickness T1 of the first main area 211a in the front-to-back direction and the thickness T2 of the first sub-area 212a in the front-to-back direction. For example, the height H of the partition 213 can be less than the thickness T1 of the first main area 211a in the front-to-back direction and greater than the thickness T2 of the first sub-area 212a in the front-to-back direction. Such a partition 213 can be arranged in the center of the filter holder 210 and support the filter portion 220. In addition, the wall portion 213a can be formed in the partition 213.

[0085] The wall portion 213a can divide the first filter area 210a and the second filter area 210b.

[0103] In addition to the above structure, according to the second embodiment of the present invention, the filter holder 210 may further include a rib 215 and a gripping portion 216. Fig.10, a second embodiment of the present invention is described. In the description of the second embodiment, the differences compared with the above embodiment are mainly described, and the same descriptions and figure numerals as the above embodiment are used.

[0104] The rib 215 may prevent the second filter member 222 and the third filter member 223 supported on the second edge portion 212 from being detached from the second edge portion 212. Such a rib 215 may extend from the second edge portion 212 toward the inner side of the second edge portion 212.

[0105] A grip portion 216 may be provided at any one of the first edge portion 211 and the second edge portion 212 to allow a user to easily grip the filter assembly 200. Such a grip portion 216 may be made of a flexible material so as to be sandwiched between the second edge portion 212 and the support frame 130 when the filter assembly 200 is mounted on the frame 100.

[0106] In this way, the filter assembly 200 according to the embodiment of the present invention can simultaneously mount or remove the plurality of filter components 221, 222, 223 on or from the frame 100 by supporting a plurality of filter components 221, 222, 223 of a plurality of types on one filter holder 210. In this case, the plurality of filter components 221, 222, 223 can be easily transported and replaced from the frame 100.

[0107] In addition, since the edge portions 211 and 212 of the filter holder 210 have a tapered shape, the filter assembly 200 can be mounted on the frame 100 with directionality. In this case, the filter assembly 200 can be prevented from being mounted on the frame 100 in a manner that the first filter member 221 is arranged on the outer side of the frame 100 than the second filter member 222. In addition, the filter assembly 200 can be prevented from being mounted on the frame 100 in a manner that the second filter member 222 is arranged on the upper side than the third filter member 223.

[0108] In addition, in the air purifier 1 according to the embodiment of the present invention, since the plurality of wall portions 213a are supported on the protruding ribs 133 of the frame 100, it is possible to prevent eddy currents from being generated between the filter assembly 200 and the frame 100. In this case, the air passing through the filter assembly 200 does not stay between the filter assembly 200 and the frame 100 and can stably flow toward the fan assembly 300.

[0109] In addition, the air purifier 1 controls the first fan unit 311 opposite to the first filter area 210a to operate at a higher rotation speed than the second fan unit 312. In this case, even if the first filter area 210a has a higher pressure difference than the second filter area 210b, air can smoothly pass through the first filter area 210a.

[0110] Although the embodiments of the present invention are described above with specific implementation forms, this is only an example, the present invention is not limited thereto, and should be understood to have the widest scope of following the technical ideas disclosed in this specification.
