Description

Air cleaner and control method thereof TECHNICAL FIELD

The present invention relates to an air purifier and a control method thereof.

Cooking often results in the release of harmful pollutants and carcinogens such as smoke, oil mist, or other pollutants. In many kitchens, a kitchen hood is installed on a stove or cooktop to blow out residual pollutants. However, kitchen hoods are generally not properly maintained and therefore less efficient. Oil, dust, smoke and other contaminants can remain in the air after cooking and can stick to cabinets, countertops or other surfaces, which can be staph, E. coli, and pneumoconiosis. It can be a breeding ground for bacteria such as Streptococcus pneumoniae (which can cause meningitis, pneumonia, sinusitis and other infections) Other harmful substances that occur during cooking include carbon monoxide, nitrogen dioxide, formaldehyde, volatile organic compounds, and There may be black carbon, and polycyclic aromatics hydrocarbons, which can pose a health hazard.

Most of the fine dust generated during baking or frying is in the form of an oil mist, which can adhere to and clump in a common air purifier or kitchen hood. The oil mist can block contaminated air from entering the suction grill of the air purifier or the air purifier, and reduce the efficiency of the air purifier. If the oil mist is attached to the air purifier or near the exhaust grille of the air purifier, the oil will spread further into the interior space as a whole, increasing pollution.

Korean Application No. 10-2005-0007482 is that an ultraviolet lamp is arranged between a pair of perforated plates and a photocatalyst is coated on the perforated plate to activate the photocatalyst by the light emitted from ultraviolet rays, thereby enhancing the effect of sterilizing and deodorizing air. However, if contaminants are deposited on the photocatalyst, there is a problem that it is difficult to remove.

Korean Patent Registration No. 10-0582006 discloses an air purifier for a table for filtering fine smoke (eg, cigarette smoke). The table air purifier sucks air from the front side, discharges the air through the left and right openings, and pushes the air back toward the front. This flow of air is destructive or annoying to the users around it, and the exhausted purified air can also be remixed with the contaminated air and recycled. The filter inside the table air purifier cannot be easily replaced, and the table air purifier needs to be installed near a wall outlet.

Republic of Korea Utility Model 20-0484435 discloses a small attachable air purifier. The small attachable air purifier is not easily cleaned and must be disassembled to be cleaned.

Republic of Korea Patent Registration No. 10-1411356 discloses that a filter in the form of a wound roll is released and used, and after use, it is wound on a take-up roller and then cut with a cutting unit to be discharged. However, since the filter is cut without gripping the front and rear portions of the cutting position when cutting the filter, there is a problem in that the filter cannot be maintained in a fully unfolded state, and warpage occurs in the direction in which the cutting blade is pressed, so that the filter cannot be accurately cut.

In other words, although there is a conveying roller in front of the roller on which the used filter is wound, the conveying roller simply guides the conveying of the filter, and there is no structure to fix the filter so that it is fully unfolded, so that the filter is not cut off. There wasn't.

In addition, in this case, after discharging the used filter, the filter and the paper must be directly wound on the take-up roll so that the filter can be moved by the operation of the take-up roll. In this way, the work of re-installing the filter on the take-up roll has to be done in a very narrow space, so there is a problem of inferior efficiency.

For example, the elastic member may be located under the outer case 100, and the latch may be located under the support 250, but the positions of the elastic member and the latch are not limited. When the roll filter cartridge 200 slides into the upper opening of the outer case 100, the elastic member can be compressed and the support 250 closes the upper opening of the outer case 100. It may be fastened to the case 100. When a downward force is applied to the top of the tip cover 210, the support 250 may be unlocked from the outer case 100. The restoring force of the elastic member pushes the roll filter cartridge 200 slightly upward so that the user can easily grasp the upper portion of the tip cover 210 to separate the roll filter cartridge 200 and the roll filter 600 ) Can be removed or replaced.

The display and the user interface may be located above the tip cover 210. Alternatively, the display and the user interface may be located on a part of the outer case 100.

Unwinding or cutting (600))

The air purifier 1 may include a sensor assembly for monitoring the level of dust, oil, odor, or other harmful gas (eg, carbon monoxide) in the air around the air purifier 1. Alternatively or in addition to this, the air purifier 1 is used to determine when the prefilter 500 needs to be cleaned and/or the roll filter 600 needs to be unscrewed and cut. It may have a sensor for comparing the flow rate and the flow rate of the exhausted air. Still alternatively or additionally, the filter sheet 610 may be configured to change its color when it needs to be replaced, and the user can hang the filter sheet 610 exposed through the slit 420 of the rear cover 400. When a user sees whether a part has a specific color (eg, purple, yellow, brown, etc.), the air purifier 1 may be controlled to control the roller 620 to release it. The display may display the level of contamination detected from the sensor assembly.

4 and 5, the gear assembly 220 can ensure smooth supply of the filter sheet 610 toward the filter cutter 700 (FIG. 4) through a plurality of gears and a plurality of rollers. In addition, the gear assembly 220 may alternatively be referred to as a filter guide or a supply assembly. The support 250 of the roll filter cartridge 200 may have an upper portion or a frame 204 extending horizontally across the upper portion. The upper part 204 may accommodate the upper part or the first roller 225. The first bracket 203 may be located under the upper part 204 to provide a side part having a through hole, and the shaft 223 of the upper roller 225 is It can be inserted into the barrel. A lower portion of the first bracket 203 may have an opening through which the lower portion of the upper roller 225 is exposed. The upper part 204 of the support 250 may cover the upper part of the upper roller 225. The first bracket 203 may have an additional tip portion or wall 203b to provide additional support and stiffness to the first bracket 203.

The second bracket 202 may be positioned under the first bracket 203 to accommodate the lower portion or the second roller 224. Like the first bracket 203, the second bracket 202 may have a side portion having a through hole, and the shaft of the lower roller 224 may be inserted into the through hole of the second bracket 202. . An upper portion of the second bracket 202 may have an opening through which an upper portion of the lower roller 224 is exposed. The second bracket 202 may have an additional tip portion or wall 202b to provide additional support and rigidity to the second bracket 202.

The shaft of the lower roller 224 may be connected to the roller gear 222. The roller motor 221 may be located under the roller gear 222 and may be coupled to the side wall 201 of the roll filter cartridge 200. The roller motor 221 may be coupled to an inner gear, and the roller motor 221 may be configured to rotate the roller gear 222 through an inner gear that rotates the lower roller 224.

The upper roller 225 and the lower roller 224 may be configured to contact each other, and the filter sheet 610 may be supplied between the upper roller 225 and the lower roller 224. When the roller motor 221 is turned on, the roller gear 222 may rotate in a direction supplying the filter sheet 610 toward the rear end cover 400 (clockwise direction in FIG. 5). The upper roller 225 may not be driven by the roller motor 221 and instead may rotate through friction when the filter sheet 610 is moved by the lower roller 224. The upper roller 225 primarily serves as a guide for maintaining the position of the filter sheet 610 and prevents the filter sheet 610 from slipping from the lower roller 224. Alternatively, the upper roller 225 may be driven by a separate gear and motor configuration, which may be synchronized with the roller gear 222 and the roller motor 221 driving the lower roller 224.

The rear surface of the support 250 may include an opening (eg, a slit or a slot) through which the filter sheet 610 passes toward the filter cutter 700. After passing through the slit on the rear surface of the support 250, the filter sheet 610 may pass through the slit 320 of the frame 300.

In the roller motor 221 or the roller gear 222, there may be an additional gear sensor for detecting the motion of the roller motor 221 and/or the motion of the internal gear or the roller gear 222. The controller may be electrically connected to the gear sensor, and supplied through the upper roller 225 and the lower roller 224 based on the number of rotations of the roller motor 221 and/or the internal gear or the roller gear 222 It is possible to determine how much the amount of the filter sheet 610 is. The roller motor 221 can be automatically turned off when the controller determines that a predetermined amount of the filter sheet 610 has been supplied through the upper roller 225 and the lower roller 224, that is, the roller motor (221), when at least one of the inner gear, or the roller gear 222 achieves a predetermined number of rotations. The predetermined amount and/or the predetermined number of rotations of the filter sheet 610 may be set based on the height of the tip opening of the case.

Alternatively or additionally, the filter sheet 610 may have marks or protrusions at predetermined intervals, and a display sensor (eg, a light or laser sensor) is used when the display or protrusion passes through the sensor. It may be located in one of the first bracket 203 or the second bracket 202 to detect. The predetermined amount of the filter sheet 610 supplied through the upper roller 225 and the lower roller 224 may be determined based on a predetermined number of marks or protrusions passing through the sensor. The roller motor 221 may be automatically turned off after the display of a predetermined number passes through the sensor. When the filter sheet 610 is formed to have a dotted line, the blade 701 (FIG. 11) of the filter cutter 700 may be omitted, while the clamp 750 of the filter cutter 700 is It may remain so that the user can tear off the filter sheet 610 for disposal. Details of the filter cutter 700 will be described with reference to FIGS. 6A to 11.

Referring to FIG. 6A to FIG. 11, the filter cutter 700 is supplied through the slit 320 (FIG. 4) of the frame 300 and then cuts the filter sheet 610. It can be located at the rear end. The filter cutter 700 includes a blade 701 configured to move between both sides of the frame 300 to cut the filter sheet 610 and a clamp that presses and holds the filter sheet 610 during the cutting process. 750).

The rear surface of the frame 300 may include a jaw 330 to provide a plane through which the filter sheet 610 is supplied. The jaw 330 may include an opening (eg, a slit or slot) 330a into which the blade 701 is inserted to cut the filter sheet 610. The blade motor 702 may be located under the jaw 330 and may be accommodated in the blade housing 704. A portion of the clamp 750 may be positioned above the blade 701 or moved to press and hold the filter sheet 610' on both sides of the blade 701 during cutting You can have space to do The configuration of the blade 701 and the blade motor 702 and details of the operation of the blade 701 will be described later.

The frame 300 may include a beam 350 for separating and supporting the filter cutter 700 from the fan 310. A V-shaped protrusion 360 may extend below the lower portion of the beam 350 to protect and further support the fan 310 from the filter cutter 700.

The clamp 750 may include a rectangular clamp cover or housing 740 extending between both sides of the frame 300. The first, second, and third layers 710, 720, and 730 having a predetermined contour may be located inside the clamp cover 740. The first layer 710 may be an upper layer, the second layer 720 may be an intermediate layer, and the third layer 730 may include the filter sheet 610 and the filter sheet 610 through a lower opening of the clamp 750. / Or may be a lower layer configured to contact the jaw (330). Alternatively, a lower portion of the clamp cover 740 may be in close contact with the filter sheet 610 and/or the jaw 330, and the third layer 730 may be formed under the clamp cover 740. I can contact you.

The first layer 710 and the second layer 720 may be laminated on top of each other to form a rectangle and are wedge-coupled, and may also be referred to as first and second (ie, upper and lower) wedges. . The lower surface of the second layer 720 may be relatively flat, and may be coupled to the flat upper surface of the third layer 730. The third layer 730 may be a holding block that presses and holds the filter sheet 610 ′. The third layer 730 may have an upper portion having an upper surface and a lower portion having a bottom surface configured to hold the filter sheet 610. The first layer 710 may be movable or slidable with respect to the second layer 720, while the third layer 730 is fixed to the second layer 720 (e.g., Can be glued or pressed through grooves and protrusions) As an alternative example, the second and third layers 720 and 730 may be integrally formed or permanently fixed to form one integrated holding block.

The lower surface of the third layer 730 may include an opening (eg, a slit or slot) 730a (FIG. 10B) aligned with a slit 330a of the jaw 330 of the frame 300. . The blade 701 may protrude through the jaws 330 and the slits 330a and 730a of the third layer 730, respectively, while the lower surface of the third layer 730 is the clamp 750 Depending on the state of the filter sheet 610 can be moved up and down to clamp or unclamp.

The upper surface of the second layer 720 is inclined downward from the first side of the frame 300 (ie, the right side of FIG. 6B) toward the second side of the frame 300 (ie, the left side of FIG. 6B). Thus, the thickness of the second layer 720 on the first side is greater than the thickness of the second layer 720 on the second side. The lower surface of the first layer 710 may be inclined downward from the first side of the frame 300 toward the second side of the frame 300, so that the thickness of the first layer 710 at the second side Is greater than the thickness of the first layer 710 on the first side.

The clamp 750 may further include a jaw 755 and a leaf spring 760 to facilitate a clamping operation. The jaw 755 may be formed as a stepped portion inside the clamp cover 740, but the disclosed embodiments are not limited. For example, the jaw 755 may alternatively be coupled (eg, bonded or welded) to the upper surface of the jaw 330 of the frame 300. The upper portion of the third layer 730 may be longer than the lower portion to have first and second (ie, right and left) ends protruding in the horizontal direction past the lower portion. The first and second (ie, right and left) jaws may be positioned below the first and second ends of the third layer 730, respectively. The first and second (i.e., right and left) leaf springs 760 may be coupled to the upper portions of the first and second jaws 755, respectively, or alternatively above the first and second jaws 755 It may be coupled to the lower portion of the upper portion of the third layer 730 at the position of. The lower portions of the first and second ends of the third layer 730 are located on the upper surfaces of the first and second leaf springs 760, respectively, and the leaf spring 760 includes the jaws 755 and the third It is located between the layers 730.

The lower portion of the third layer may extend downward toward the jaw 330. Both sides of the clamp cover 740 may be fixed to a sidewall of the frame 300, and a lower portion of the third layer 760 may be exposed through a lower opening of the clamp cover 740. As an alternative, if the jaw 755 is formed on the jaw 330 of the frame 300 instead of the clamp cover 740, the clamp cover 740 has a shape corresponding to the shape of the third layer. Since the branch may have a bottom surface, the clamp cover 740, not the third layer 730, contacts the plate spring 760 and the filter sheet 610.

When the clamp motor 741 is turned on, the clamp gear 742 can rotate to push the first layer 710 in a horizontal direction with respect to the teeth 711 and the second layer 720 thereby. have. Due to the slope of the lower surface of the first layer 710 and the upper surface of the second layer 720, the second and third layers 720 and 730 are formed of the slits 330a and 730a from which the blades 701 protrude. In the front and rear portions of the filter sheet 610, the filter sheet 610 may be pressed downward. Cutting by the blade 701 is more effective when the filter sheet 610 is held down on the jaw 330. A more detailed description of the gripping operation will be described with reference to FIGS. 6B and 6C.

6B and 6C are views from the front side of the air purifier 1, while FIGS. 7 and 8 are views from the rear side of the air purifier 1. 6B and 6C omit the clamp cover 740. In describing the operation of the clamp 750, lowercase letters indicate variables, while uppercase letters indicate constants or fixed values. Some of the angles, slopes, sizes, and ratios of FIGS. 6B and 6C are exaggerated to emphasize the motion of the first layer 710 with respect to the second layer 720.

Referring to FIG. 6B, in the initial or open state of the clamp 750, a gap g may be provided between the jaw 330 of the frame 300 and the bottom of the third layer 730. The gap g may be aligned with the slit 320 formed on the front surface of the frame 300. The gear assembly 220 (FIG. 4) may supply the filter sheet 610 through the slit 320 and the gap g before cutting.

In the initial state of the clamp 750, the first and second leaf springs 760 are not compressed so that each initially has the _{same height h s as L1. Initially, the height h g} of the gap g may be equal to G1. _{The height h 1} from the jaw 330 to the upper surface of the first layer 710 may be equal to H1. _{At the thickest point, the height h 2} from the chin 330 to the upper surface of the second layer 720 may initially be equal to H1. _{Initially, the thickness t1 c} of the first layer 710 on the central vertical axis c may be equal to D1. In the axis (c), the thickness t2 _c of the second layer 720 may be equal to D2.

Referring to FIG. 6C, the clamp gear 742 may be rotated in a first rotation direction (eg, counterclockwise in FIG. 6C ). The clamp gear 742 may be coupled to the teeth 711 formed on the first layer 710, and the first layer 710 may be pushed toward the first side (ie, right). As the first layer 710 is pushed to the right, the thickness t1 _c of the first layer 710 in the axis c may increase larger than D1. However, since the second layer 720 does not move, the thickness t2 _c of the second layer 720 may remain constant at the thickness of D2.

The clamp cover 740 may prevent the first layer 710 from rising and may keep the top surface of the first layer 710 flat. Therefore, instead of the first layer 710 rising, the second layer 720 may descend. The clamp cover 740 may further have a length in the horizontal (ie, left and right) direction longer than the length in the horizontal direction of the first layer 710 in order to allow the movement of the first layer 710. Because of the increased thickness t1c of the first layer 710, the second layer 720 can be pushed down and the height h ₂ from the jaw 330 to the upper surface of the second layer 720 is H1 Decreases to a lower level. The change (Δh _{2 ) in the height h 2} of the second layer 720 from the jaw 330 is the same as the change (Δt1 _{c ) in the thickness t1 c} of the first layer 710.

The second layer 720 can push the third layer 730 downward to compress the leaf spring 760, so that the height h _s of the leaf spring 760 is reduced to less than L1. The change in _{the height h s} of the leaf spring 760 _{(Δh s} ) may be the same as the change in the thickness t1 _{c (Δt1 c} ), and therefore the change in the _{height h 2 of the second layer 720 (Δh 2} It can also be the same as ).

As the third layer 730 moves downward, the bottom portion of the third layer 730 can approach the jaw 330 so that the height h _g of the gap g becomes smaller than G1. Decreases. The variation in the height h ₂ of the gap (g) change (Δh _g) of the height h _g of the change (Δt1 _c) in the thickness t1 _c, the second layer (720) (Δh _2), and the leaf spring ( 760) may be equal to the change in _{height h s (Δh s ).}

Therefore, during the movement of the clamp 750, Δt1 _c = Δh ₂ = Δh _s = Δh _g . _{On the other hand, the height h 1} from the chin 330 to the upper surface of the first layer 710 remains constant in H1, and additionally, the horizontal position and the thickness t2 _c of the second layer 720 are also the same. The horizontal position of the third layer 730 and the thickness of the third layer 730 along the axis c may remain constant. As the horizontal position of the first layer 710 changes, the vertical positions of the second layer 720 and the third layer 730 change, whereas the vertical height of the first layer 710 remains the same. have. Since the first layer 710 is not lowered, the teeth 711 may remain coupled with the clamp gear 742, so that the first layer 710 is positioned on the second side (ie, the left side). It is prevented from sliding toward.

Since the downward force applied to the first side (ie, the right side) of the second layer 720 may be slightly greater than the downward force applied to the second side (ie, the left side) of the second layer 720, The bottom surface of the third layer 730 may be flat on the filter sheet 610 so that downward force is equalized. When fully compressed, the length of the lower portion of the third layer 730 may be greater than or equal to the sum of the height of the jaw 755 and the height of the leaf spring 760 (h _{s ). As a result, the third} The bottom portion of the layer 730 may contact the jaw 330 of the frame 300 to close the gap g in the final or closed state of the clamp 760.

In the final or closed state of the clamp 760, the gap g will be closed so that _{the height h g of the gap is equal to zero. In such a state, the thickness t1 c} on the axis c of the first layer 710 may be equal to D3, which is greater than D1. _{The height h s} of the leaf spring 760 may be equal to L2, which is smaller than L1. L2 may represent a partially compressed state or a completely compressed state, depending on the length of the lower portion of the third layer 730. _{The height h 2} from the jaw 330 to the upper surface of the second layer 720 may be equal to H2, which is smaller than H1. Since Δt1 _c = Δh ₂ = Δh _s = Δh _g , thus |(D3-D1)| = |(H2-H1)| = |(L2-L1)| = G1.

Cutting may be easiest when the clamp 760 is in a closed state, while supply of the filter sheet 610 may be easiest when the clamp 750 is in an open state. The supply of the filter 600 may occur according to the installation of a new roller 620 in the roll filter cartridge 200, and may occur when the filter sheet 610 is contaminated and needs to be cut. Immediately after cutting the contaminated portion of the filter sheet 610, the clamp 750 presses and holds the uncut edge of the front end of the filter sheet 610, and the filter sheet facing the prefilter 500 The clean portion of 610 can be kept in a closed state to keep it in a taut state. As an alternative, the clamp 750 may be open, and the filter sheet 610 may be primarily fixed between the upper roller 225 and the lower roller 224. Additionally, after the clamp 750 is opened, the first filter sheet 610 pulls out a sufficient amount (eg, 1 inch) of the filter sheet 610 so that the filter sheet 610 is clamped during the operation of the air purifier 1. It can be slightly released by the roller 225 and the second roller 224. After the filter sheet 610 is slightly released, the clamp 750 may return to the closed state.

In order to open the gap g, the clamp gear 742 may be rotated in a second rotational direction opposite to the first rotational direction (that is, clockwise in FIGS. 6B and 6C). ), the thickness t1 _c of the first layer 710 may be reduced to approach D1 while reducing a downward force applied to the leaf spring 760. The restoring force of the leaf spring 760 allows the leaf spring 760 to expand so that the height h _s of the leaf spring 760 increases to approach L1. The third layer 730 may be pushed upward by the restoring force of the leaf spring 760, and the second layer 720 is pushed upward so that the second layer ( 720 ₂ h height of the upper surface of) is increased to approach the H1. As the third layer 720 moves upward, the gap g is opened so that the height h _g of the gap g approaches G1. The leaf spring 760 may alternatively be implemented with another type of spring or an elastic material (eg, a coil spring). As another alternative, the jaw 755 may be omitted, the length of the leaf spring 760 may be increased and/or the length of the lower portion of the third layer 730 may be decreased accordingly. In such an alternative, the length of the lower portion of the third layer 730 may be greater than or equal to the length of the leaf spring 760 in a fully compressed state.

7 to 11, the blade motor 702 and the blade housing 704 may be positioned under the jaws 330 and clamp 750. The blade motor 702 may be inside or coupled to the side of the blade housing 704. The blade 701 may be a metal blade or a metal blade positioned between the base 701a and the cap or cover 701b. The base 701a may be fixed to the upper surface of the blade housing 704, and the blade 701 includes a slit 330a in the jaw 330 and a third layer 730 of the clamp 750 It may protrude through the slit (730a) for. The cap 701b may cover an upper portion of the blade 701 to prevent accidental cutting of a finger during replacement of the blade 701, and the first and second sides of the blade 701 ( That is, left and right) may be configured to cut the filter sheet 710. The cap 701b may extend to the slit 730a of the third layer 730, while the height of the blade 701 is such that the side surface of the blade 701 overlaps the filter sheet 610. It is configured, it can be seated on the jaw 330 of the frame 300.

The rack 340 may protrude from the rear surface of the frame 300 between the jaw 330 and the beam 350. The rack 340 may extend between side surfaces of the frame 300. The lower surface of the rack 340 includes teeth configured to engage the blade gear 703 which can be rotated by the blade motor 702. When the blade motor 702 is turned on, the blade gear 703 moves the blade motor 702, the blade housing 704, and the blade 701 between both ends of the frame 300. You can move along (340). The slits 330a and 730a may have left and right lengths shorter than or equal to the left and right lengths of the rack 340, and the blades 701 are the jaws 330 and the third layer 730 of the clamp 750 It can move along the slits 330a and 730a of.

A portion of the blade housing 704 may be stepped or protruded forward so as to be seated on the upper surface of the rack 340 to provide added support to the blade housing 704. The upper surface of the rack 340 may be additionally coated with a material configured to reduce friction between the blade housing 704 and the rack 340 during movement of the blade gear 703 along the rack 340. have.

The blade gear 703 may move from the first side to the second side of the fan housing 300 so that the second side of the blade 701 cuts the filter sheet 610. When the filter sheet 610 needs to be cut again, the blade gear 703 is the second side of the fan housing 300 so that the first side of the blade 701 cuts the filter sheet 610. It may move from the side to the first side of the fan housing 300. Since the blade gear 703 can move across the rack 340 once per cutting, the blade 701 can be preserved. Although the drawings show that the teeth of the rack 340 are formed on the bottom surface, alternatively, the teeth of the rack 340 may be formed on the upper surface.

4 and 9A to 9B, the clamp 750 may be positioned to contact the rear surface of the frame 300. The blade housing 704 may be adjacent to the rear surface of the frame 300, but may not contact the rear surface of the frame 300 to reduce friction during movement. Alternatively, the rear surfaces of the blade housing 704 and the frame 300 may be coated with a slippery material to facilitate movement.

9A to 10B, the blade housing 704 may be positioned under the clamp 750. The blade may protrude into the clamp 750 through the slit 330a of the jaw 330 and through the slit 730a of the third layer 730. The slit 730a formed in the third layer 730 of the clamp 750 may form a moving path of the blade 701. The left and right lengths of the slit 730a may be longer than the first length of the filter sheet 610, so that the filter sheet 610 is at the leftmost position of the blade 701 and the rightmost position of the blade 701.

For example, the blade 701 is the clamp 750 and the frame 300 so that the blade 701 cuts the filter sheet 610 at a tensioned portion between the clamp 750 and the gear assembly 220. ) Can be located between the backs. In this alternative embodiment, the clamp 750 may be away from the rear surface of the frame 300 and the blade housing 704 is held adjacent to the rear surface of the frame 300. The slit 330a may be formed on the jaw 330 at a position between the clamp 750 and the rear surface of the frame 300, and the blade 701 and the cap 701b are the slit 330a. ) Can protrude through and be exposed. The filter sheet 610 may be tensioned between the upper roller 225 and the lower roller 224 (FIG. 5) and the clamp 750, and the blade 701 is The tensioned part can be cut. The filter sheet 610 may be fixed between the upper roller 225 and the lower roller 224 during the operation of the fan 310, and the clamp 750 may be disposed of the rear cover 400 for disposal by the user. ) Can be opened after cutting so that the filter sheet 610 can be easily pulled to the outside.

As another alternative example, when the blade 701 is not inserted into the clamp 750, the blade 701 is the clamp assembly as close to the clamp as possible to cut a portion of the filter sheet 610. It may be located on the back of 750. In this alternative embodiment, the clamp 750 may be adjacent to the rear surface of the frame 300, while the blade housing 704 and the rack 340 have the filter sheet 610 After being supplied through 750, the blade 701 may protrude rearward so that the blade 701 is very close to the rear surface of the clamp 750 (instead of penetrating it) so that the filter sheet 610 is effectively cut. . In this embodiment, after the filter sheet 610 is cut, the clamp 750 maintains a state in which the clean portion of the filter sheet 610 facing the prefilter is tensioned during the operation of the air purifier 1. It can be kept closed to keep it. The embodiments disclosed herein are not limited to this configuration of the clamp 750, the rollers 225 and 224, and the blade 701.

Referring to FIG. 7 to FIG. 11 again, the operation of the filter cutter 700 may be operated for a predetermined time after the operation of the gear assembly 220 is completed, and this time is determined by the number of rotations of the gear motor 221. It may be determined based on or based on a mark passing through the gear assembly 220. The predetermined time may be described as a time required for the clamp 750 to press and hold the filter sheet 610.

Alternatively or in addition, the operation of the filter cutter 700 may be automatically started after the clamp 750 is lowered. The clamp 750 may include a sensor for detecting the rotation of the clamp gear 742, and when the clamp gear 742 stops rotating, the blade motor 702 is the filter sheet ( 610) can be operated to cut.

The control method of the filter cutter 700 is not limited. As another alternative, the blade motor 702 may be operated when a gear sensor detects a predetermined number of rotations of the clamp gear 742. The predetermined number of rotations may correspond to the number of rotations of the clamp gear 742 required for the first layer 710 to move a sufficient distance to close the gap g and press and hold the filter sheet 610. I can. As another alternative, the display sensor may be located on the base 701a of the blade 701 to detect a mark on the filter sheet 610 or a cut line, and the operation of the blade motor 702 is performed by the clamp gear ( It may not start until 642 stops rotating and the display sensor of the blade 701 detects a mark on the filter sheet 610.

In order to maintain the path of movement of the blade 701, a motor or gear sensor may be positioned to sense the rotation of the blade motor 702 or the blade gear 703. The blade motor 702 may not be turned off until the gear sensor detects a predetermined number of rotations of the blade motor 702 or the blade gear 703. The predetermined number of rotations may correspond to the blade housing 704 that is moved completely across the filter sheet 610. As an alternative, if the indication sensor is located on the base 701a of the blade 701, the indication sensor can detect the number of marks or cut lines through which the blade 701 has passed, and the blade motor 702 may be turned off when the display sensor detects a predetermined number of indications, which may be the same as the number of indications positioned across the filter sheet 610.

A user may control the blade motor 702 through a user interface to indicate when to cut the filter sheet 610. The controller may determine how many filter sheets have been cut in order to predict when the filter sheet 610 is about to be exhausted through a gear sensor or a motor sensor in the gear assembly 220. The display on the outer case 100 and/or the roller filter case 200 may indicate to the user when the roll filter 600 should be replaced.

Referring to FIG. 4 to FIG. 11, the user may install the roll filter 600 on the roll filter cartridge 200 by placing the roller 620 at the bottom and unwinding the filter sheet 610 upward. I can. The filter sheet 610 may be supplied through the upper and lower rollers 225 and 224 of the gear assembly 220. The end of the filter sheet 610 may be maintained between the upper roller and the lower rollers 225 and 224 so that the filter sheet 610 remains fixed when the fan 310 inhales air. The end of the filter sheet 610 may be additionally supplied through the gap g and the slit 320 by the gear assembly 220 so as to be further fixed under the clamp 750 during the operation of the fan 310. . The tip cover 210 may be press-fit onto the support 250 of the roll filter cartridge 200 to further fix the filter sheet 610 in place.

The filter sheet 610 may collect oil mist and fine dust. A general filter for collecting oil mist may be difficult to clean, but the filter sheet 610 may be simply discarded. The controller may determine whether the filter sheet 610 has reached a predetermined level of contamination or higher, and may determine to operate the roller motor 221 and operate the blade motor 702.

The determination of the level of contamination by the controller may be based on the implementation of various sensors. For example, there may be an air flow sensor located in front of the filter sheet 610, and there may be another air flow sensor located behind the filter sheet 610, and the controller can compare the measured values. . When the difference in the sensed airflow is greater than a predetermined amount, the controller may determine that the filter sheet 610 has reached a predetermined level of contamination or higher. As another example, an air quality sensor may be located inside the roll filter case 200 to detect air quality (eg, oil level, dust level, carbon dioxide or smoke level, carbon monoxide level, or odor level), and The controller may determine that the filter sheet 610 is at or above a predetermined level of contamination based on a value detected by the air quality sensor.

As another example, the filter sheet 610 may be configured to change color when the filter sheet 610 absorbs a predetermined amount of oil or dust or based on the weight of the filter sheet 610, and the user There may be an optical sensor or other sensor configured to input an instruction and/or notify the controller when the color of the filter sheet 610 has changed. In another example, the cooking frequency may be determined based on a sensor that detects the operation of the pan 310 or based on data stored in a memory that tracks a user instruction, and the cooking frequency reaches a predetermined number of times or more. When so, the controller may evaluate that the filter sheet 610 has reached a predetermined level of contamination.

When the controller determines that the filter sheet 610 has reached a predetermined level of contamination, the clamp motor 741 can be turned on to open the clamp 750, and the roller motor 621 is the frame 300 ) May be turned on to supply the filter sheet 610 between the upper roller and the lower rollers 225 and 224 through the gap g of the clamp assembly 750 and the slit 320. The controller can automatically stop the roller motor 621 when the filter sheet 610 is supplied or released by a predetermined amount. As described above, this It can be based on the number of revolutions, indication sensors, etc. As the filter sheet 610 is unwound, a new, clean portion of the filter sheet 610 may extend between the roller 620 and the top surface of the roll filter cartridge 200, while contaminated A part of the portion may be suspended from the outside of the slit 420 of the rear cover 400.

When the filter sheet 610 is released by a predetermined amount, the controller may control the clamp motor 741 to close the clamp 650. The controller, as described above, based on the operation of the display sensor in the clamp motor 741, the gear assembly 220, the gear assembly 220, or the base 701a of the blade 701, the blade The motor 702 can be operated. The user may input an instruction to cut the filter sheet 610 when the user sees that the filter sheet 610 is suspended outside the slit 420 of the rear cover 400 through the user interface.

The controller crosses the filter sheet 610 based on the operation of the blade motor 702 or based on a display sensor located at the base 701a of the blade 701 (for example, the frame ( It may be determined to cut from the first side of 300) to the second side of the frame 300). Since the blade 701 can be cut to both the left and the right side, when the blade 701 is cut across the filter sheet 610, the controller will cut the filter sheet 610 next time. Until, the blade motor 702 may not be operated in the reverse direction of the blade gear 703. Alternatively, the blade 701 may be configured to be cut from one side, and in this case, the controller may operate the blade motor 704 in the reverse direction of the blade gear 703 and the frame 300 The blade 701 may be returned to the first side. The user may discard the cut-out portion of the filter sheet 610. The implementation of the method of controlling the unwinding and cutting of the filter sheet 610 by the controller is not limited to the embodiments described above.

The bases (110, 110') of the air purifier (1, 1') can be directly driven by an external commercial power source through an electric plug, and a wireless charging pad (for example, a wireless charging pad (2)) Can be omitted.

As another alternative to the implementation of the coupling of the rollers 620 in the roll filter cartridge 200, the roller 620 may be located in a case or container located under the roll filter cartridge 200, the filter The sheet 610 may be supplied through a slit in the upper portion of the case or in the lid. The roller 620 may be freely rotated within the case, which may prevent the roller 620 from moving when the filter sheet 610 is pulled.

As an alternative to the blade housing 704 sliding along the rack 340, the stepped portion of the blade housing 704 may not contact the rack 340 while leaving a very small gap. In this embodiment, the stepped portion may mainly serve to balance the center of gravity of the blade housing 704.

As an alternative to using time, cooking frequency, filter color, or airflow difference to determine the contamination level of the filter sheet 610', there may be a weight sensor for detecting the roll sensor 600, and the When the weight has been increased by a predetermined amount or more, the controller may determine that a predetermined level of contamination has been reached.

The clamp 750 may be implemented in various ways. As one simple implementation, the clamp 750 may include a block having a rack or teeth formed on the left side and/or the right side. The gear may be located on the left side and/or the right side of the frame 300 so as to couple with the rack. When the gear rotates in the first direction, the block may be raised to form the gap g. When the gear rotates in a second direction opposite to the first direction, the block may be lowered to close the gap g. The clamp 750 may omit a spring, a jaw, and a retaining block or wedge having a special shape. The gear can be rotated manually or alternatively can be rotated automatically via a motor.

As another simple example, the clamp 750 may be implemented similarly to a hole punch and may include a retaining block having the same shape as the third layer 730 so as to be seated on a jaw having a lever and a spring. The user can press the lever to move the holding block downward. The latch can be locked with the clamp 750 so that it is maintained in a closed state, and the clamp 750 is opened so that a gap g is formed and the latch is unlocked, and the restoring force of the spring is applied to the retaining block. Alternatively, the plate can be pushed upwards.

As another example, the clamp 750 may include a spring and a retaining block mounted on the jaw, and at least one piston for moving the retaining block downward. There may be two pistons to uniformly apply downward force to the filter sheet 610. When the piston does not move the retaining block downward, the restoring force of the spring may lift the retaining block upward to form the gap g.

Similarly, the clamp 750 may include a spring, a retaining block seated on the jaw, and a cam rotated to contact the retaining block. The cam can be elliptical or eccentric. The camshaft, which is in a horizontal direction parallel to the upper surface of the retaining block, can be inserted into the cap at a position in which one side (ie, the long side) of the cam can be longer than the opposite side (ie, the short side) of the cap. . The cam can be rotated so that the long side contacts the retaining block and pushes the retaining block down to hold the filter sheet and close the gap g. In order to open the clamp 750, the cam may be rotated 180 degrees to a position in which the long side extends away from the holding block, and the restoring force of the spring contacts the short side of the cam and the The holding block can be pushed upward to form a gap (g). The filter sheet 610 may be provided with two cams whose phase is rotated to maintain a uniform and distributed downward force.

The embodiment of the clamp 750 having a spring that is compressed during downward motion remains in an open position to form the gap g in the resting or neutral state of the spring. As an alternative to this embodiment, the position of the spring and the retaining block is configured such that when the retaining block is lifted to form a gap g, the spring is compressed, and then the gap g is closed. The retaining block is released, and the restoring force of the spring closes the gap g. In this alternative embodiment, the neutral or initial state of the clamp 750 may be a closed position instead of an open position.

Another implementation of the clamp 750 may be more similar to the implementation with the first and second layers 710 and 720 having a wedge-like shape. Instead of having a clamp gear 742 that engages the teeth 711 of the first layer 710, the thinner end of the first layer 710 may have a blunt end, and a spring (e.g. a coil spring ) May extend in a horizontal direction from the thicker end of the first layer 710. The first knob, button, or handle may be located on the thicker end of the first layer 710 protruding to the outside of the outer case. The second knob, button, or handle may be located at the end of the spring. To lower the clamp 750, the user can press the first knob, which can move the first layer 710 horizontally and compress the spring. There may be a latch or a locking hole for locking the first layer 710 in its place. To raise the clamp 750, the latch can be released, and the restoring force of the spring increases so that the third layer 730 forms a gap g, and the first layer 710 is It can be moved back to its initial position.

Embodiments of the clamp 750 are not limited and may be implemented in various ways such as a hydraulic pump, a piston, a cam, a motor, a rack and pinion, a gear, and a linear actuator.
