Description

  The present invention relates to an air cleaner that removes dust in flowing air.

There is an apparatus provided with a prefilter, a deodorizing filter, and a dust collection filter as an air cleaner (for example, patent documents 1).
In the air cleaner of Patent Document 1, after relatively large dust contained in the suctioned air which has been suctioned first is collected by a pre-filter, and then odor components in the suctioned air are absorbed and removed by a deodorizing filter. The dust collection filter collects relatively small dust contained in the intake air.

JP-A-2015-187540

However, in the air cleaner described in Patent Document 1, when relatively large dust adheres to the prefilter, the ventilation resistance at the time of suctioning air increases. An increase in the air flow resistance prevents the air from being drawn, resulting in a decrease in the air cleaning ability or an increase in the rotational noise of the blower fan.
In order to prevent that, usually, cleaning is required to remove dust attached to the pre-filter. The cleaning of the pre-filter is troublesome, such as suctioning dust using a vacuum cleaner or the like, removing the pre-filter from the apparatus for cleaning, etc., and the burden on the user has increased.
An object of the present invention is to provide an air purifier that can be easily maintained without the trouble of cleaning the prefilter.

The air cleaner according to the present invention includes a blower, a cyclone dust collecting part that swirls sucked air to collect dust, and a filter dust collecting part that collects dust of passing air in a housing. The cyclone dust collecting unit is positioned upstream of the filter dust collecting unit.
The air cleaner according to the present invention comprises a blower, a paper pack collecting unit for collecting sucked air with a replaceable paper pack filter, and a filter collecting unit for collecting dust of passing air. The paper pack collecting unit is disposed upstream of the filter dust collecting unit.

  According to the above-mentioned configuration, since the pre-filter is not used, cleaning of the pre-filter is not necessary and maintenance can be simplified.

The dust collection case 31 is configured to be able to visualize collected dust. Here, the dust collection case 31 is made of a translucent material. More specifically, it is formed of a transparent or translucent (light transmitting) resin material. The bottom portion 31 a of the dust collection case 31 is exposed from the case outlet 53 of the housing.
(3-3) Auxiliary Filter Means The auxiliary filter means 32 is formed in a conical shape in which the bottom portion 31a side of the dust collection case 31 is tapered, and the peripheral wall portion has a mesh (mesh) like auxiliary filter portion 35 and an auxiliary filter A bent portion (cone portion) 36 which extends from the end of the portion 35 in the radial direction toward the bottom portion 31 a of the dust collection case 31 is provided.

(3-4) Dust Collection The air taken in from the suction port 51 passes through the guide passage from the outer flow passage 33 of the main body 30, and becomes a swirling air flow that spirals around the outer peripheral side of the auxiliary filter portion 35. The swirling airflow is directed to the bottom portion 31 a of the dust collection case 31 while swirling along the inner circumferential surface of the dust collection case 31. Thereafter, the bottom portion 31a of the dust collection case 31 is abutted and the direction is changed to the discharge passage side of the internal flow passage 34 in the swirling axis direction, and dust passing through the outside of the barb portion The swirling air flow toward the bottom portion 31 a of the dust collection case 31 is brought back. That is, clean air from which dust has been removed passes through the auxiliary filter 35 and is sucked into the blower 2 (filter dust collector 4) via the discharge passage.
Dust contained in the swirling airflow is directed radially outward (inner circumferential surface side) of the dust collection case 31 by the centrifugal force of the swirling airflow, and is removed from the air. When the rotation of the blower fan 22 stops, the dust that has entered the bottom portion 31 a side of the dust collection case 31 from the barbed portion 36 loses the turning force and falls.

(4) Filter dust collection part This will be mainly described with reference to FIG.
The filter dust collecting unit 4 is provided on the upstream side of the blower unit 2. The filter dust collection unit 4 includes a dust collection filter 41. That is, the filter dust collecting unit 4 collects dust from the air by passing through the cyclone dust collecting unit 3 and air sucked by the air blowing unit 2 passing through the dust collection filter 41.
In addition to the dust collection filter 41, the filter dust collection part 4 here is equipped with a deodorizing filter 43. The dust collection filter 41 is provided adjacent to the upstream side of the deodorizing filter 43. The dust collection filter 41 and the deodorizing filter 43 have a flat plate shape. The dust collection filter 41 and the deodorizing filter 43 here have a disk shape, and are disposed such that their main surfaces are vertical. In other words, it is disposed to be orthogonal to the swirling axis of the swirling air flow generated in the cyclone dust collecting unit 3. That is, the air sucked by the blower 2 passes through the dust collection filter 41 and the deodorizing filter 43 in the thickness direction.

The filter dust collection unit 4 includes a dust collection frame 45, and the dust collection filter 41 and the deodorizing filter 43 are detachably attached to the dust collection frame 45. Here, the front wall 50a of the housing 5 is removable from the housing body 50, and the dust collection filter 41 and the deodorizing filter 43 are provided on the dust collection frame 45 so as to be removable from the front. Thereby, the dust collection filter 41 and the deodorizing filter 43 can be easily taken out from the housing 5, and the dust collection filter 41 and the deodorizing filter 43 can be easily cleaned and replaced.
The filter on the downstream side of the filter dust collection unit 4, here the downstream side of the deodorizing filter 43, is the inlet of the discharge passage 25 and is sucked by the blower 2.

(5) Humidification part This will be mainly described with reference to FIG.
The humidifying unit 6 is provided to supply mist to the air discharged from the discharge port 52. The humidifying unit 6 includes a water tank 63 and a mist generating unit 61 that receives water from the water tank 63 and generates a mist.
The mist generation means 61 here is an ultrasonic atomization type which makes water into fine particles by ultrasonic waves. The mist generated by the mist generation means 61 is sprayed to the outside of the housing 5 from the blowing port 54 of the upper wall 50 b via a passage (not shown).
As shown in FIG. 1 and FIG. 2, the blowing port 54 is provided substantially at the center in the longitudinal direction of the discharge port 52 which is long in the width direction. The spray port 54 has a trumpet shape that spreads in the spray direction. As a result, the mist is sprayed over the entire air discharged from the discharge port 52.
The water tank 63 is detachably accommodated in the housing 5. The water tank 63 is easily taken out by opening the lid 55 of the housing 5.

(6) Operation Unit The operation unit 7 is provided on the upper wall 50 b of the housing 5 as shown in FIGS. 1 and 2. The operation unit 7 has a control circuit that controls each unit based on the operation buttons 71 and 73 and the content of the operation by the operation buttons 71 and 73. The control board is provided on an operation board attached to the upper wall 50b on the back side.

(7) Orientation Adjustment Unit The orientation adjustment unit 8 changes the orientation of the plate member 81 disposed on the rear side of the discharge port 52 and supported rotatably around the rotation axis extending in the width direction, and the plate member 81 And changing means 83. The changing means 83 includes a rotating gear that meshes with the gear of the plate member 81, and a drive motor that rotates the rotating gear. Thereby, the plate member 81 swings by the rotation of the drive motor.

(8) Sterilizing Unit The sterilizing unit 9 is, as shown in FIG. 3, configured by ultraviolet irradiation means 91 for irradiating ultraviolet light to the swirling air flow swirling in the cyclone dust collection unit 3. The ultraviolet irradiation means 91 is disposed inside the dust collection case 31. For this reason, the sterilizing part 9 (ultraviolet irradiation means 91) here constitutes a part of the cyclone dust collecting part 3.
The “inside of the dust collection case 31” referred to here includes not only the inside of the dust collection case 31 but also the space facing the internal space of the dust collection case 31. For example, as shown in FIG. 3, even when the ultraviolet ray irradiating means 91 is disposed in the main body 30 of the cyclone dust collecting unit 3, it is assumed that "the ultraviolet ray irradiating means 91 is disposed inside the dust collection case 31". .
The dust collection case 31 is preferably formed of a material resistant to ultraviolet light, and for example, PMMA (acrylic) or PC (polycarbonate) can be used. Further, in consideration of the leakage of ultraviolet light, it is preferable that the dust collection case 31 be configured by adding an ultraviolet absorbent.

3. Use (1) Air Cleaning When air cleaning is performed, the operation buttons 71 and 73 are operated to drive the air blowing unit 2. As a result, the blower fan 22 is rotated, and air is sucked into the cyclone dust collection unit 3 from the suction port 51. In the cyclone dust collecting unit 3, the dust contained in the air is centrifugally separated by the swirling air flow, and is collected and accumulated on the bottom portion 31 a side in the dust collection case 31.
Since the cyclone dust collecting part 3 and the filter dust collecting part 4 are provided on the upstream side of the air blowing part 2, the passage resistance on the downstream side of the air blowing part 2 can be reduced. As a result, the volume of air discharged from the discharge port 52 can be secured, and clean air (clean air) can be sent to a wide range of the room. Further, by reducing the passage resistance, the load of the drive motor 21 of the blower unit 2 can be reduced, and an increase in noise can be prevented.

During air cleaning, ultraviolet light is irradiated by the ultraviolet irradiation means 91 to the swirling air flow swirling in the cyclone dust collecting unit 3. Thus, the air sucked into the housing 5 can be sterilized and discharged. Further, since the ultraviolet irradiation means 91 emits ultraviolet light inside the dust collection case 31, the inside of the dust collection case 31 can be kept clean.
During the air cleaning, the air discharged from the discharge port 52 is changed in direction by the plate member 81. Thereby, the clean air can be sent to a wide range in the room.

  During air cleaning, mist is sprayed from the mist generating means 61 to the air discharged from the discharge port 52. Thereby, the mist can be diffused to a wide range in the room. In particular, since the mist is sprayed in the vicinity of the discharge port 52 where the air blowing power (discharge force) is strongest, it is possible to reduce the possibility of the floor getting wet due to the mist that can not get on the air.

(2) Cleaning Since the cyclone dust collecting unit 3 is provided on the upstream side of the filter dust collecting unit 4, it is possible to prevent large dust from adhering to the dust collection filter 41. Thereby, the dust adhering to the dust collection filter 41 and the deodorizing filter 43 can be reduced, and the lifetime of these can be extended.
Further, the collected dust is accumulated in the dust collection case 31 so that the cyclone dust collection unit 3 is configured to be able to take out the dust collection case 31. Therefore, the dust collection case 31 can be cleaned more easily than in the case of using the pre-filter.
In particular, since the dust collection case 31 can visualize the accumulation state of the dust inside, the timing for removing the dust can be easily understood.
The front wall 50 a of the housing 5 is configured to be removable, and the dust collection filter 41 and the deodorizing filter 43 of the filter dust collection unit 4 are configured to be removable with respect to the dust collection frame 45. Therefore, the dust collection filter 41 and the deodorizing filter 43 can be easily cleaned and replaced.
