Description

[Technical Field]

[0001] The present invention relates to an air purifier that purifies the air by removing dust, pollen, odorous components, PM2.5, viruses, and other particles from the air. [Background technology]

[0002] Popular air purifiers include a dust collection filter section in the main body that purifies the air by removing dust in the air drawn in through the intake section by causing it to adhere to a dust collection filter, and an electric dust collector section that, when a dirt sensor (dust sensor or gas sensor) determines that the air is highly dirty (high dust level), controls the flow of electricity to electrostatically charge the dust in the air passing through and electrostatically attracts the dust to a dust collection electrode, thereby removing it and purifying the air.The air purifier is configured so that the air passes through a dust collection section such as the dust collection filter section or electric dust collector, and is then blown out from the outlet section by the blower. For example, in such an air purifier, a unitized dust collection filter section is removably attached to the unit mounting section of the main body, and the unitized electric dust collection section is removably attached to the upstream or downstream side of this dust collection filter section.

[0003] In addition, the electric dust collecting section of such an air purifier has a number of ionizing electrodes arranged in parallel, which serve as ionizing electrodes, and a number of dust collecting electrodes arranged in parallel at intervals from each of these ionizing electrodes.When the dirt is severe (dust level is high) and the purification capacity needs to be increased, current is passed to the ionizing electrodes by controlling the flow of current through the electrode terminal section which is in contact with and conductive to the voltage supply section.For example, by applying a voltage to each ionizing electrode as a positive electrode and each dust collecting electrode facing it at a distance as a negative electrode, dust in the air passing through this is electrostatically attracted to each negative dust collecting electrode and removed, thereby purifying the air.

[0004] Conventionally, such electric dust collectors have required periodic maintenance, for example, to remove (clean) the adsorbed dust. Therefore, as in Patent Document 1, for example, not only has the electric dust collector been configured as a detachable unit so that it can be removed from the main body, but it has also been proposed that the ionization electrode unit equipped with an ionization electrode and the dust collection electrode unit equipped with a dust collection electrode can each be detached separately from the main body to facilitate cleaning (to improve maintainability).

[0005] However, in the conventional configuration, the components are merely detachable, and the detachment operation is not easy. Furthermore, because the detachment is not easy, there is a risk that the numerous ionizing electrodes may be damaged or dropped, resulting in breakage of the ionizing electrodes. In other words, the configuration does not allow the electric dust collector to be easily removed, and the dust collecting electrode section having numerous dust collecting electrodes to be easily slid apart from the ionizing electrode section having numerous ionizing electrodes of the electric dust collector to expose the numerous dust collecting electrodes, and it is not possible to easily brush off, wipe, or wash the dust collecting electrodes.

[0006] Furthermore, for example, Patent Document 2 proposes an electric dust collecting unit in which a first part (ionization electrode part) that holds the positive ionization electrode and a second part (dust collection electrode part) that holds the negative dust collection electrode are connected by a hinge mechanism so that they can be opened and closed freely, and when closed, an appropriate distance can be maintained between the positive and negative electrodes. This is also proposed as a detachable unit that can be attached and detached freely to the main body, and after removing it from the main body, the first and second parts can be easily and safely opened and separated via the hinge mechanism.

[0007] However, because the dust collection electrode part (second part) cannot be completely separated from the ionization electrode part (first part), it is not possible to easily brush off, wipe, or wash off dust from the dust collection electrode part (second part), making it difficult to maintain. Furthermore, there is a risk of damaging the hinge mechanism during maintenance. [Prior art documents] [Patent documents]

[0009] The present invention has identified and solved such problems, and aims to provide an innovative air purifier that is easy to maintain, has excellent practicality, and has no risk of breakage, and in which the electric dust collecting unit can be easily removed from the main body, and the dust collecting electrode unit can be easily slid away from the ionizing electrode unit of the electric dust collecting unit along a slide engagement guide mechanism, so that there is no risk of damaging the ionizing electrode during the sliding separation operation, and because the ionizing electrode can be exposed by sliding it away from the ionizing electrode, dust can be easily brushed off, wiped off, or washed with water from the dust collecting electrode without damaging the ionizing electrode.

DETAILED DESCRIPTION OF THE INVENTION

[0023] The best mode for carrying out the present invention will now be briefly described with reference to the accompanying drawings, illustrating the operation of the present invention.

[0024] The outside air is drawn into the main body 1 from the intake section 2 by the blower section 5, and this air passes through the dust collector 3 attached to the unit mounting section 12 of the main body 1, whereby dust in the air is adsorbed and removed, purified, and then discharged from the blower section 4.

[0025] Specifically, for example, an electric dust collector 3 serving as a dust collector 3 configured as a detachable unit is attached to the unit mounting section 12 of the main body 1, and a dust collection filter section 15 equipped with a dust collection filter 14 as another dust collector 3 is also detachably attached downstream or upstream of the electric dust collector 3, and the outside air is drawn in from the intake section 2 of the main body 1 by the blower section 5, and as this air passes through each dust collector 3 (electric dust collector 3 and dust collection filter section 15), dust is removed and the air is purified and discharged from the upper outlet section 4.

[0026] That is, for example, dust in the air is captured and removed by dust collection filter 14 of dust collection filter section 15 attached midway along the air flow, and if electric dust collector section 3 is attached upstream of this in a layered state, and the airflow rate of blower section 5 is controlled according to the detection status of a dirt sensor (dust sensor or gas sensor), for example, and when this dust sensor detects that the dirt is severe (dust level is high), power is controlled to operate electric dust collector section 3, which electrostatically charges the dust in the air and electrostatically attracts it to dust collection electrode 8 for removal, then the purification capacity can be increased appropriately (according to the degree of dirtiness of the air) by this electric dust collector section 3.

[0027] In other words, in the present invention, the dust collecting section 3 may be this electric dust collecting section 3 alone, but as mentioned above, the dust collecting section 3 may be configured by stacking the dust collecting filter section 15 and the electric dust collecting section 3 side by side, so that when the capacity of the dust collecting filter section 15 is insufficient or to strengthen it, for example, the configuration may be such that air passes through both sections, and the electricity is controlled constantly or as needed to operate the electric dust collecting section 3 in addition to the dust collecting filter section 15, thereby increasing the purification capacity.

[0028] To explain further, the electrostatic precipitator 3 of the present invention is configured to include an ionization electrode section 7 having, for example, a plurality of linear ionization electrodes 6, a dust collection electrode section 9 having a plurality of dust collection electrodes 8 arranged at intervals from each of the ionization electrodes 6 and electrostatically attracting dust in the passing air, and an electrode terminal section 11 which is electrically connected to a voltage supply section for applying a voltage to each of the ionization electrodes 6 and each of the dust collection electrodes 8 spaced apart from them, and which applies electricity to the ionization electrode 6.

[0029] Therefore, by controlling the flow of electricity such as by turning the voltage supply unit on and off, the ionization electrodes 6 are energized via the electrode terminal units 11, i.e., a voltage is applied so that each ionization electrode 6 becomes a positive electrode and each dust collection electrode 8 becomes a negative electrode, whereby dust in the passing air is electrostatically charged and electrostatically attracted to the negative dust collection electrode 8, thereby purifying the air.

[0030] The electrostatic precipitator 3 is configured as a detachable unit that is detachably mounted on the unit mounting portion 12 of the main body 1, and can be easily removed from the main body 1 for maintenance. Furthermore, the removable electrostatic precipitator 3 is slidable along the length of the ionizing electrodes 6, that is, along the length of the collecting electrodes 8 that are spaced apart between the ionizing electrodes 6, using a slide engagement guide mechanism 24 as a guide. The ionizing electrode unit 7 (unit) and the collecting electrode unit 9 (unit) are separable into two parts. Therefore, the two parts can be smoothly separated by sliding the collecting electrode unit 9 from the ionizing electrode unit 7. Furthermore, this slide engagement separation can be easily performed by sliding the collecting electrode unit 9 away from the ionizing electrode unit 7, guided by the slide engagement guide mechanism 24, or the two parts can be inserted and slid into engagement to form a combined unit. Therefore, the collecting electrodes 8 of the collecting electrode unit 9 can be safely exposed from an appropriate slide engagement completion position without damaging the ionizing electrodes 6.

[0031] That is, after the electric dust collecting unit 3 (unit), which is configured as a detachable unit, is pulled out and removed from the main body 1, or while it is still attached to the unit attachment part 12 of the main body 1, the dust collecting electrode part 9 (pull-out unit part) can be slid and separated from the ionization electrode part 7 (main body unit part) of the electric dust collecting unit 3 using the slide engagement guide mechanism 24 as a guide, and the dust collecting electrode 8 of the dust collecting electrode part 9 can be slid out and exposed easily and safely.

[0032] Furthermore, when the two parts are separated and then slid back together to form a combined unit, the configuration is provided with a slid engagement completion positioning means 13 which is positioned at the slid engagement completion position where the dust collection electrode 8 is disposed in an interposed state with a gap between the ionization electrodes 6, thereby maintaining the combined unit state. Therefore, the slid separation can be easily performed and the slid engagement completion can be easily maintained, so that the dust collection electrode 8 can be slid apart and exposed easily without risk of further damaging the ionization electrode 6, and dust can be easily brushed off, wiped off, or washed with water from the dust collection electrode 8 without damaging the ionization electrode 6, resulting in excellent maintainability (easy cleaning). [Example]

[0033] A specific embodiment 1 of the present invention will be described with reference to the drawings.

[0034] In this embodiment, an intake section 2 is provided at the bottom of the main body 1, which draws in outside air from all four directions (front, back, left, and right) of the bottom, i.e., from all directions around the bottom, to the top center by blowing air from the bottom to the top of the main body 1 by an air blowing section 5 (air blowing fan unit) provided in the main body 1, and a dust collecting section 3 is provided at the bottom upstream of the air blowing section 5 of the main body 1, i.e., on the entire middle of the air passage, to remove dust in the air and purify it.

[0035] Specifically, the dust collection section 3 in this embodiment is configured so that these are layered over the entire surface of the air passage, and furthermore, on the lower upstream side of the dust collection filter section 15, which is equipped with a dust collection filter 14 that captures and removes dust in the air to purify the air, and an electric dust collector 3 that electrostatically adsorbs and removes dust in the air to purify the air, and the air blower 5 is provided above the dust collection section 3 consisting of the dust collection filter section 15 and the electric dust collector 3 on the downstream side, and above the air blower 5, a blower 4 that blows out the air purified by the dust collection section 3, a control operation section, etc. are provided.

[0036] Furthermore, the dust collection section 3 may consist solely of the electric dust collection section 3, but in this embodiment, as described above, the dust collection section 3 is made up of a dust collection filter section 15 and an electric dust collection section 3 arranged in a vertically layered configuration, and when the purification capacity of the dust collection filter section 15 is insufficient, that is, when the detection situation occurs in which the dust level detected and determined by the dirt sensor (dust sensor) is high and the purification capacity of the dust collection filter section 15 is insufficient, the current is controlled to operate the electric dust collection section 3 (operating the electric dust collection section 3 in addition to the dust collection filter section 15), thereby increasing the purification capacity.

[0037] More specifically, the electrostatic precipitator 3 in this embodiment is configured to include an ionization electrode section 7 having a configuration in which a number of ionization electrodes 6 made of ionization wires are arranged side by side at intervals, a dust collection electrode section 9 having a number of dust collection electrodes 8 arranged side by side at intervals and spaced from each of the ionization electrodes 6, each of which is arranged at intervals and electrostatically attracts dust in the air that passes through, and electrode terminal sections 11 (contact terminal sections) that bring into electrical contact with a voltage supply section that applies voltage to each of the ionization electrodes 6 and each of the dust collection electrodes 8 spaced apart from them.

[0038] Furthermore, the electrostatic precipitator 3 in this embodiment is a single combined part in which the ionization electrode unit 7 and the dust collection electrode unit 9 are slidably engaged and integrated, and this is configured as a detachable unit that can be attached and removed by smoothly sliding horizontally using a slide guide mechanism as a guide to the unit attachment unit 12 of the main body 1 (note that the guide rails 30 provided on the left and right upper parts of the ionization electrode unit 7 of the electrostatic precipitator 3 shown in the figure are part of this slide guide mechanism). However, in this embodiment, the electrostatic precipitator 3 can be slid horizontally while attached to the unit attachment unit 12 of the main body 1. The dust collection electrode part 9 held by the engagement completion positioning means 13 is pulled out using the slide engagement guide mechanism 24 as a guide, that is, the dust collection electrode part 9, which requires frequent maintenance, can be pulled out while the ionization electrode part 7 remains attached to the unit mounting part 12, and further, after pulling out the dust collection electrode part 9, the remaining ionization electrode part 7 can be pulled out from the unit mounting part 12 using the slide guide mechanism (guide rail 30) as a guide by pinching the pull-out knob part 10, as needed.

[0039] That is, the electric dust collecting section 3 configured in this detachable unit is configured so that the slide engagement guide mechanism 24 can slide freely along the length of the many ionizing electrodes 6 and the many dust collecting electrodes 8 that are arranged at intervals between the ionizing electrodes 6, and the ionizing electrode section 7 and the dust collecting electrode section 9 can be slidably separated into two parts (two units). When the dust collecting electrode section 9 (drawer unit part) slides away from the ionizing electrode section 7 (main unit part) to form two parts, the many dust collecting electrodes 8 of the dust collecting electrode section 9 become exposed, improving maintainability.

[0040] In addition, in this embodiment, when the ionization electrode unit 7 and the dust collection electrode unit 9 are separated into two parts and then slidably engaged again to form a combined unit state by being attached to the unit attachment part 12, the slide engagement completion positioning means 13 is provided to position the combined unit state at the slide engagement completion position where the dust collection electrode 8 is disposed between the ionization electrodes 6 with a gap therebetween, and to maintain this combined unit state.

[0041] Specifically, the electrostatic precipitator 3 configured as a detachable unit comprises an ionization electrode section 7 (main unit part) in which numerous linear ionization electrodes 6 are arranged side by side at intervals within a case section 16 having pull-out knobs 10 on the left and right front ends, which constitute the unit body of the detachable unit, and a pull-out handle 18 at the front end of a slide engagement section 17 that slides into and engages with the case section 16, and a dust collection electrode section 9 (pull-out unit part) on the opposite side (rear side) of the slide engagement section 17 in which, when slide-engaged and connected to the ionization electrode section 7, numerous ionization electrodes 6 and numerous dust collection electrodes 8 that are spaced apart from each other are arranged side by side in an exposed protruding state.

[0042] In addition, the slide engagement completion positioning means 13 of this embodiment is configured to have a tapered surface engaging portion 19 that engages with the tapered surface at the completion position when the slide engagement portion 17 of the dust collection electrode portion 9 is slide-engaged and connected to the case portion 16 of the ionization electrode portion 7.

[0043] Specifically, the slide engagement portion 17 at the front of the dust collection electrode portion 9 is slid into the front of the case portion 16 of the ionization electrode portion 7 to complete the slide engagement, and tapered surface engagement portions 19 that increase in left-right and top-bottom width as they move toward the slide engagement direction (insertion direction) are provided on the left-right and top-bottom inner surfaces of both engagement portions, so that when slide insertion is facilitated and the slide engagement is completed, the left-right and top-bottom tapered surface engagement portions 19 come into face-to-face contact and engage with each other, and the combined unit state after slide engagement is completed is positioned without any rattle and is well maintained.

[0044] As described above, in this embodiment, the slide engagement guide mechanism 24 is slidable along a guide, and the ionization electrode section 7 (main unit) and the dust collection electrode section 9 (drawer unit) are configured to be separable into two parts, and when these two parts are separated, the many dust collection electrodes 8 of the dust collection electrode section 9 are exposed. Therefore, the dust collection electrodes 8 can be easily slid apart and exposed without risk of damaging the ionization electrodes 6, and dust can be easily brushed off, wiped off, or washed with water from the dust collection electrodes 8 without risk of damaging the ionization electrodes 6, improving maintainability (easy cleaning).

[0045] Furthermore, in this embodiment, since slide engagement completion positioning means 13 is provided to maintain the coupled unit state, sliding separation can be easily achieved and the completed sliding engagement can be easily maintained. Furthermore, as described above, this slide engagement completion positioning means 13 is configured with tapered surface engaging portion 19 that engages with the tapered surface when slidingly connecting slide engagement portion 17 of collection electrode portion 9 to case portion 16 of ionization electrode portion 7. Therefore, since a large force is not required for the engagement / disengagement operation and a face-to-face engagement state is achieved with a sufficient tapered area, there is no risk of accidentally damaging, breaking, or deforming the ionization electrode 6 during the engagement / disengagement operation, and slide separation, completion of slide engagement, and its retention can be achieved more safely and smoothly. Therefore, the positional relationship between the ionization electrode 6 and the collection electrode 8 is always maintained, and there is no risk of a decrease in dust collection performance.

[0046] Furthermore, the dust collection electrode section 9 of this embodiment is configured such that a number of dust collection electrodes 8 are protruding in an exposed state toward the rear from a slide engagement section 17 (pull-out handle section 18) that slide-engages and connects to the case section 16 of the ionization electrode section 7, and these dust collection electrodes 8 are configured to be formed from a metal plate, and a number of long slit-shaped openings are formed in this metal plate in the slide engagement direction (insertion direction) so that a number of dust collection electrodes 8 are machined and formed at intervals, and when slide engagement is completed in these slit-shaped openings, an ionization electrode 6 is disposed in each, and these dust collection electrodes 8 and ionization electrodes 6 are configured to face each other.

[0047] The slide engagement flange portion 22 is integrally formed on the left and right sides of the metal plate on which the numerous dust collection electrodes 8 are formed, and the case portion 16 of the ionization electrode portion 7 is provided with the slide guide portion 23 (groove-shaped rail portion) that slides and engages with the slide engagement flange portion 22 when inserted, thereby forming the slide engagement guide mechanism 24.

[0048] Therefore, the electric dust collecting section 3 is provided with the slide engagement guide mechanism 24 consisting of the slide engagement flange section 22 and the slide guide section 23, which acts as a guide for slide engagement, making the two parts safe and easily slidable and separable.

[0049] Further explaining the electric dust collecting unit 3 of this embodiment, when the slide engagement portion 17 of the dust collecting electrode portion 9 of this embodiment is slid into the front portion of the case portion 16 of the ionization electrode portion 7 as described above, the slide engagement is completed by the slide engagement completion positioning means 13 (the face-to-face contact of the tapered surface engagement portions 19) and the parts are integrated into one. This slide engagement portion 17 is configured as the pull-out handle portion 18, and a finger hook recess for pull-out is provided on the back side thereof (not shown), and a rib is provided at the back of this finger hook recess to prevent the finger from going any further in, thereby increasing rigidity and preventing contact between the dust collecting electrode 8 and the fingers as well as preventing deformation of the dust collecting electrode 8.

[0050] Furthermore, on the left and right sides of the metal plate that forms the dust collection electrode 8, the slide engagement flange portions 22 are formed in the shape of ribs that are folded back in the vertical direction as described above, so that the deformation strength of the dust collection electrode portion 9 can be easily increased, and on the side of the case portion 16 of the ionization electrode portion 7, the slide guide portions 23 are provided in the shape of rail grooves that are open downward, thereby constituting the slide engagement guide mechanism 24.

[0051] Furthermore, an insertion insertion tip 28 having different heights at the center and left and right portions is provided at the insertion tip of the metal plate that is machined to form the dust collection electrode 8 of the dust collection electrode unit 9, and an insertion guide insertion port 29 that corresponds to this step is provided at the front insertion portion of the case unit 16 of the ionization electrode unit 7, and the slide engagement guide mechanism 24 is configured so that the slide engagement flange 22 smoothly engages with the slide guide unit 23 and is guided in slide engagement by this positioning function and insertion guide function during insertion.

[0052] In addition, misalignment prevention ribs 32 are provided on the left and right, above and below the position where the insertion tip 28 is completely inserted, i.e., at the rear of the case 16 of the ionization electrode 7, and the misalignment prevention ribs 32 and wall surfaces are provided to sandwich the insertion tip 28 and prevent misalignment, so that the dust collection electrode 8 is held in the appropriate position.

[0053] Furthermore, the dust collection electrodes 8, which are formed in large numbers by processing the metal plates, are formed in an upright state to increase the deformation strength of the dust collection electrodes 8 and to increase the electrostatic attraction surface that faces the linear ionization electrodes 6 disposed between them.Furthermore, the shape is configured to allow good air flow above and below, to be easily washed with a brush, etc., and to be excellent in maintainability.

[0054] In addition to the slit-shaped openings between the dust collecting electrodes 8, openings may also be provided on the sides, for example, to further reduce pressure loss in the air flow path and to further improve drainage after cleaning.

[0055] In addition to the completion of the sliding engagement by the tapered surface engaging portions 19, a concave-convex engaging structure or a crossover engaging structure using small protrusions or the like may be provided to give a slight clicking sensation.

[0056] In this embodiment, the cover plate 20 covers the opening for pulling out the collecting electrode 9 from the case 16 of the ionization electrode unit 7 and covers the end of the ionization electrode 6 of the ionization electrode unit 7, and is provided with slide-through slits 21 through which a large number of collecting electrodes 8 slide. This protects the ionization electrodes 6, and the slide engagement guide mechanism 24 allows each collecting electrode 8 to slide through the slide-through slits 21 easily.

[0057] Although not shown, the slide engagement completion positioning means 13 may also be configured as follows: A locking mechanism may be provided on the slide engagement portion 17, which is the pull-out handle 18 of the collection electrode unit 9, by performing an engagement / disengagement operation in which a hook engagement portion is disengaged from an engagement hole by pressing with a finger, thereby releasing the locked state and allowing the collection electrode unit 9 to be pulled out from the ionization electrode unit 7. Specifically, when the electric precipitator unit 3, which is configured as a detachable unit, is attached to the unit mounting portion 12 of the main body 1, the locking mechanism provided as the slide engagement completion positioning means 13 may be engaged and disengaged to pull out the collection electrode unit 9 while the ionization electrode unit 7 is fixed to the unit mounting portion 12, and the entire electric precipitator unit 3 (the electric precipitator unit 3 as a detachable unit in the combined unit state) may be pulled out from the unit mounting portion 12 by pulling out the electric precipitator unit 3 without performing the engagement / disengagement operation.

[0058] With this configuration, it is possible to select whether to pull out the entire electric dust collecting unit 3 by pushing it out, or to pull out only the dust collecting electrode unit 9 from the main body 1 without pulling out the entire electric dust collecting unit 3, resulting in excellent maintainability.

[0059] In this embodiment, the case 16 of the ionization electrode unit 7 is provided with a mesh portion 25 that covers the many ionization electrodes 6 and prevents the ionization electrodes 6 from being touched by hands, and the mesh portion 25 is provided on both the upstream and downstream sides of the many ionization electrodes 6 arranged side by side.

[0060] Furthermore, in this embodiment, the mesh portion 25 prevents the intrusion of foreign matter, and the mesh size of the mesh portion 25 covering the downstream side (upper side) which is the exhaust side (purified side) is made coarser than that of the upstream side (lower side) which is the intake side, thereby reducing pressure loss in the air supply path.

[0061] In this embodiment, the case 16 of the ionization electrode unit 7 is configured such that the opposite end of an electrode plate unit 27, one end of which becomes the electrode terminal unit 11 or is electrically connected to the electrode terminal unit 11, is fastened to an ionization electrode mounting plate unit 26 on which a large number of ionization electrodes 6 are provided.

[0062] Specifically, the rear end of each ionization electrode 6 is attached to the ionization electrode mounting plate 26, a pressing rib 31 is provided at the rear end of the case part 16 of the ionization electrode part 7 to press the ionization electrode mounting plate 26 in an appropriate position to resist the pulling of the ionization electrode 6, the ionization electrode mounting plate 26 is pressed by the base end of the electrode plate part 27 which serves as the positive wiring plate and fastened together, the tip end of the electrode plate part 27 is wired so as to be exposed from the side opening of the case part 16, and this exposed end serves as the electrode terminal part 11 which makes contact and conducts with the voltage supply part, so that the ionization electrode 6 does not tilt in the longitudinal direction and faces the dust collection electrode 8 at an appropriate position in any position, preventing a decrease in dust collection capacity.

[0063] The present invention is not limited to this embodiment, and the specific configuration of each component can be designed as appropriate. [Explanation of symbols]
