Description

  The present invention relates to a vaporizing humidifier.

The vaporizing type humidifier includes an air filter, a humidifying filter, a water tank, and a blower, a ventilation path in which they are arranged, and a water supply tank for supplying water to the water tank (see Patent Document 1).
The air filter purifies the air that passes through the air filter.
The humidifying filter uses a humidifying filter main body having water absorption and air permeability and a frame body that holds the humidifying filter main body, and absorbs water when a part of the humidifying filter main body is submerged in a water tank.

The ventilation path is provided with an inlet and an outlet. When the blower blows air, air is sucked in from the outside through the suction port. The sucked air passes through the air filter and the humidification filter in this order, and then blows out through the air outlet. At this time, the water absorbed in the humidifying filter is vaporized, and the vaporized water is discharged to the outside of the humidifying device together with the air purified by the air filter. As a result, the air outside the humidifier is purified and humidified.
The humidification filter and the water tank are pushed into a predetermined position of the ventilation path through an opening provided in the middle of the ventilation path (hereinafter referred to as a halfway opening), and are pulled out from the predetermined position of the ventilation path. The opening position of the midway opening is downstream in the ventilation direction from the air filter and upstream in the ventilation direction from the blower.

The water supply tank is arranged in a predetermined space (hereinafter referred to as a water supply space) outside the ventilation path. In the water supply space, water is supplied from the water supply tank to the water tank. The water supply space and the ventilation path communicate with each other through a midway opening.
When the blower blows air, the pressure on the upstream side in the ventilation direction with respect to the blower in the ventilation path is lower than the pressure in the water supply space. For this reason, if a blower blows in a state where the midway opening is opened, air unnecessarily flows from the water supply space to the ventilation path via the midway opening. The air flowing in through the halfway opening causes problems such as not passing through the air filter at all or not passing through the humidifying filter efficiently.

  Therefore, the midway opening is substantially airtightly closed by the partition plate that partitions the ventilation path and the water supply space and the water tank. The base plate is screwed and fixed to the water tank, and the partition plate is arranged so as to come into contact with the opening edge of the midway opening from the water supply space side when the water tank is pushed into a predetermined position of the ventilation path.

JP 2011-52877 A

In order to close the midway opening in a substantially airtight manner, the partition plate needs to be in close contact with the opening edge of the midway opening. However, there is a gap between the opening edge of the midway opening and the partition plate (hereinafter referred to as a midway gap) due to a slight dimensional error in each part of the humidifier or a misalignment when the water tank is pushed into a predetermined position of the ventilation path. May occur.
When the blower blows air in a state where such a midway gap is generated, air flows unnecessarily through the midway gap from the water supply space to the ventilation path due to negative pressure. Since such a midway gap is narrower than the midway opening, a whistling sound such as a pew is generated by the air passing through the midway gap.

  Further, the partition plate has a base end portion as a fixed end and a tip end portion as a free end. For this reason, the phenomenon that the partition plate bends due to negative pressure and abuts against the opening edge of the midway opening and the phenomenon that the partition plate recovers due to elasticity and is separated from the opening edge of the midway opening may occur alternately. In this case, an abnormal noise such as fluttering is generated.

  The present invention has been made in view of such circumstances, and the main object of the present invention is to provide a structure in which the partition plate is attached to the water tank with play so that the partition plate and the opening edge of the midway opening are provided. It is an object of the present invention to provide a humidifier that can suppress the generation of noise caused by unnecessary gaps.

A humidifier according to the present invention includes a water tank, a filter having water absorption and air permeability, a part of which is submerged in the water tank, a blower, a ventilation path through which air can flow, and at least an opening. A partition plate that partitions the inside and outside of the ventilation path by blocking a part from the outside of the ventilation path, and the ventilation path includes a suction port for sucking air from outside by blowing the blower And an outlet for blowing out the sucked air to the outside after passing through the filter, and an opening for detachably disposing the water tank and the filter therein. in the humidifier, the opening is located ventilating direction upstream side of the blower, the partition plate is attached to the tub with play in a direction crossing the the partition switching plate, before The water tank is provided in the covering part, which covers the water surface other than the part where the filter of the water stored on the side of the water tank arranged in the ventilation path can be submerged, and the covering part, and a coated side engagement portion engaged with the partition plate, wherein the cover-side engaging portion and said partition plate and said Citea Rukoto to engagable disengage with play .

In the humidifying device according to the present invention, the water tank includes a water tank main body for storing water, and the inside of the water tank main body is arranged on the side arranged in the ventilation path and on the side arranged outside the ventilation path and supplied with water. A partition wall that is partitioned and formed with a water passage hole for supplying water from a side that is disposed outside the ventilation path and is supplied with water to a side that is disposed in the ventilation path, and provided in the partition wall A partition side engaging portion that engages with the partition plate, and one end portion of the partition plate is formed in a U-shape to be placed on each of the partition wall and the peripheral wall of the water tank body. The partition side engaging portion and the partition plate are engaged with each other so as to be detachable with play.

A humidifier according to the present invention includes a water tank, a filter having water absorption and air permeability, a part of which is submerged in the water tank, a blower, a ventilation path through which air can flow, and at least an opening. A partition plate that partitions the inside and outside of the ventilation path by blocking a part from the outside of the ventilation path, and the ventilation path includes a suction port for sucking air from outside by blowing the blower And an outlet for blowing out the sucked air to the outside after passing through the filter, and an opening for detachably disposing the water tank and the filter therein. In the humidifier, the opening is located upstream of the blower in the ventilation direction, and the partition plate is attached to the water tank with play in a direction intersecting the partition plate,
The water tank is configured to divide a water tank main body for storing water, the inside of the water tank main body into a side disposed in the ventilation path and a side to be supplied outside the ventilation path and supplied with water, and the ventilation path A partition wall in which a water passage hole for supplying water from a side to be supplied and supplied to the side of the ventilation path is formed, and the partition plate is provided with the partition wall. A partition-side engaging portion that engages, and one end portion of the partition plate is formed in a U-shape placed on each of the partition wall and the peripheral wall of the water tank main body, and the partition-side engaging portion The partition plate is engaged with play with play.

In the present invention, the humidifier includes a water tank, a filter, a blower, a ventilation path, and a partition plate.
A midway opening is provided in the ventilation path, and the filter and at least a part of the water tank are detachably disposed inside the ventilation path via the midway opening. The partition plate closes the midway opening from the outside of the ventilation path.
When the blower is not blowing air, the pressure in the ventilation path is equal to the pressure outside the ventilation path. At this time, there is no particular problem even if a midway gap is generated between the partition plate and the opening edge of the midway opening.

When the blower is blowing air, the air inside the ventilation path is blown out to the outside of the ventilation path through the air outlet provided in the ventilation path. For this reason, the atmospheric pressure upstream of the air blower in the ventilation path is lower than the atmospheric pressure outside the ventilation path. That is, when the atmospheric pressure outside the ventilation path is used as a reference, the atmospheric pressure upstream of the blower in the ventilation path is a negative pressure.
At this time, the air outside the air passage is sucked into the air passage through the suction port provided in the air passage due to the negative pressure.

  At this time, the partition plate is sucked toward the ventilation path by the negative pressure. For this reason, a partition plate closely_contact | adheres to the opening edge part of a halfway opening. This is because the partition plate is attached to the water tank with play in the direction intersecting the partition plate. As a result, the generation of a midway gap between the partition plate and the opening edge of the midway opening is suppressed. Therefore, air does not unnecessarily flow into the ventilation path from the outside of the ventilation path through the midway gap.

  While the blower is blowing air, the partition plate keeps in close contact with the opening edge of the midway opening. Unlike the partition plate provided in the conventional humidifier, the partition plate provided in the humidifier of the present invention does not have a portion fixed to the water tank by, for example, screwing. Therefore, the partition plate does not bend from the fixed portion of the partition plate as a base point, and by extension, the partition plate does not recover from the bend.

In this invention, the water tank with which a humidification apparatus is provided has a coating | coated part and a coating | coated side engaging part.
The covering portion can suppress scattering of water droplets from the side disposed in the ventilation path of the water tank to the outside of the water tank. This is because the covering portion is interposed between the water on the side of the ventilation path of the aquarium and the air flowing through the ventilation path, so that the water on the side of the aeration path of the aquarium is not ventilated. It is because it suppresses a wave by contact with the air which flows along a path. Moreover, even if it undulates, it is because the water droplet which scattered from the water surface adheres to a coating | coated part, or reflects on a coating | coated part and falls to the water surface.

And since a coating | coated part coat | covers the water surface other than the part which a filter can submerge, a coating | coated part does not inhibit the water absorption of a filter.
Furthermore, since the covering portion is detachable, it is easy to remove and clean the covering portion after using the humidifying device, for example.

The covering side engaging portion provided in the covering portion and the partition plate engage with each other so as to be detachable with play. For this reason, as long as the coating | coated part has coat | covered the water surface, it is suppressed that the partition plate engaged with the coating | coated side engaging part falls unnecessarily from a water tank. Moreover, since engagement with a coating | coated side engaging part and a partition plate can be cancelled | released, a partition plate does not inhibit removal from the water tank of a coating | coated part. Moreover, since the covering side engaging portion and the partition plate are engaged with play, there is no risk that these engagements will unnecessarily fix the partition plate.
Furthermore, the engagement and the disengagement between the covering side engaging portion and the partition plate are generally simpler than, for example, screwing and screwing between the peripheral wall of the water tank or the covering portion and the partition plate.

In this invention, the water tank with which a humidification apparatus is provided has a water tank main body, a division wall, and a division side engaging part.
The partition wall partitions the inside of the water tank main body into a side disposed in the ventilation path and a side disposed outside the ventilation path. For this reason, when the blower is blowing air, it is possible to prevent the air from flowing from the outside of the ventilation path to the ventilation path through the inside of the water tank body.
Water supply to the water tank body is performed on the side disposed outside the ventilation path.

A water passage hole is formed in the partition wall. The water supplied to the side of the water tank body that is disposed outside the ventilation path is supplied to the side that is disposed in the ventilation path through the water passage hole. Such water passage holes are usually submerged during use of the humidifier. Therefore, even when the blower is blowing air, there is no possibility that air will unnecessarily flow from the outside of the ventilation path to the ventilation path through the water passage hole.
One end of the partition plate is U-shaped, and this one end is placed on each of the partition wall and the peripheral wall of the water tank body.

Placement of the partition plate on the water tank is simple, but simply placing it may cause the partition plate to drop unnecessarily from the water tank.
Therefore, the partition-side engaging portion provided on the partition wall and the partition plate engage with play. For this reason, it is suppressed that a partition plate falls unnecessarily from a water tank. In addition, since the partition side engaging portion and the partition plate are engaged with play, there is no possibility that these engagements will unnecessarily fix the partition plate.
Furthermore, the engagement between the partition side engaging portion and the partition plate is generally simpler than screwing between the peripheral wall of the water tank or the partition wall and the partition plate.

When the humidifier of the present invention is used, the partition plate can be kept in close contact with the opening edge of the midway opening while the blower is blowing air.
That is, it is possible to suppress the generation of a midway gap between the partition plate and the opening edge of the midway opening. Therefore, no whistling sound is generated due to air flowing unnecessarily into the ventilation path from the outside of the ventilation path via the midway gap.
Moreover, the abnormal noise resulting from the bending of the partition plate and the restoration from the bending does not occur.
As described above, the humidifier of the present invention can suppress the generation of noise related to the partition plate and the midway opening that the partition plate should close.

The left side and the right side of FIG. 2 are the front side and the back side of the humidifier 1, and FIG. 1 is a perspective view seen from the right side of FIG. 2 (that is, the back side of the humidifier 1). Hereinafter, the front side of the humidifier 1 is also referred to as the front side, and the back side is also referred to as the rear side. Hereinafter, the left side (or right side) of FIG. 1 is referred to as the left side (or right side) of the humidifying device 1. The vertical direction in FIG. 2 is the left-right direction of the humidifier 1.

FIG. 1 shows a state in which a rear panel 10, an air purifying unit 11, a water tray 2, a partition plate 7, a humidifying filter 51, and a water supply tank 52, which will be described later, are removed from their predetermined positions. Indicates a state in which these are attached to respective predetermined positions. However, the water supply tank 52 and the partition plate 7 are not shown in FIG.
The humidifying device 1 of the present embodiment has an air humidifying function, an air cleaning function by deodorization and dust collection, and an air cleaning function by positive ions and negative ions (hereinafter referred to as positive and negative ions).

The humidifier 1 includes a casing 6 having a vertical rectangular parallelepiped shape. The housing 6 includes a front cover 61, a top cover 62, a rear cover 63, and the like.
The humidifying device 1 is placed on the floor F in a room having a wall W and a floor F so that the rear cover 63 of the housing 6 faces the wall W.
The casing 6 includes a first ventilation path 3 for realizing an air humidification function and an air purification function by deodorization and dust collection, a second ventilation path 4 for realizing an air purification function by positive and negative ions, and A water supply space 60 is provided.

The arrangement of the first ventilation path 3 and the second ventilation path 4 in the front-rear direction is such that the first ventilation path 3 is located substantially from the rear part to the front part of the housing 6, and the second ventilation path 4 is approximately It is located at the front of the housing 6.
As for the arrangement of the first ventilation path 3 and the water supply space 60 in the left-right direction, the first ventilation path 3 is located generally from the right side of the housing 6 to the center in the left-right direction, and the water supply space 60 is substantially Located on the left side of the body 6.
The first ventilation path 3 and the second ventilation path 4 are completely partitioned. The first ventilation path 3 and the water supply space 60 communicate with each other through a rectangular midway opening 34 provided in the middle of the first ventilation path 3.

The midway opening 34 is formed in a partition wall 64 that partitions the first ventilation path 3 and the water supply space 60. Further, the midway opening 34 is closed as described later by the partition plate 7 that partitions the first ventilation path 3 and the water supply space 60 and the water tray 2.
The water tray 2 has a tray body 20 having a shape that is long in the lateral direction with an upper opening, and the tray body 20 includes a first tray 201 and a second tray 202. The first tray 201 is shorter in the front-rear direction and longer in the left-right direction than the second tray 202. The tray body 20 is detachably disposed at a predetermined position of the housing 6 so that the longitudinal direction is along the left-right direction. At this time, the first tray 201 is disposed in the first ventilation path 3, and the second tray 202 is disposed in the water supply space 60.

First, the water supply space 60 will be described with reference to FIG.
The water supply space 60 is a recess formed on the left side of the housing 6.
The water supply tank 52 is a rectangular parallelepiped container having a water tap 521 at one end in the longitudinal direction. The water supply tank 52 is detachably arranged in the water supply space 60 in an inverted posture with the water supply tap 521 side of the water supply tank 52 facing downward. At this time, the water tap 521 side of the water supply tank 52 is attached to the second tray 202 of the water tray 2.

  The water tap 521 incorporates a known constant water level valve (not shown). When the water supply tank 52 is mounted on the second tray 202, the constant water level valve is pushed up by a push-up projection 203 (see FIG. 11 described later) standing on the bottom wall of the second tray 202 to be in an open state. . As a result, the water stored in the water supply tank 52 is supplied to the second tray 202. The water supplied to the second tray 202 is supplied to the first tray 201 through a water passage hole 23 (see FIG. 11) described later. At this time, water of a constant water level L (see FIG. 3 described later) is stored in the tray body 20 by the action of the constant water level valve.

Next, the 1st ventilation path 3 is demonstrated with reference to FIG.1 and FIG.2.
The 1st ventilation path 3 has the filter accommodating part 3a and the blowing ventilation path 3b which are mutually connected. The first air passage 3 is provided with a first suction port 31, a first air outlet 32, and a midway opening 34.
The first suction port 31 is open to the rear cover 63 of the housing 6, and the outside of the humidifier 1 and the filter housing portion 3 a communicate with each other through the first suction port 31.

The rear panel 10 is detachably attached to the housing 6 so as to close the first suction port 31. However, the rear panel 10 is formed with a plurality of vent holes 100, 100,. For this reason, the air which flows through the 1st suction inlet 31 is the air which flows through the vent holes 100,100, ... in more detail. The ventilation holes 100, 100,... Are closed by a prefilter (not shown), and this prefilter collects coarse dust contained in the air flowing into the filter housing portion 3a via the first suction port 31. And remove.
The first air outlet 32 opens in the top cover 62 of the housing 6, and the air outlet 3 b communicates with the outside of the humidifier 1 through the first air outlet 32.

When the first blower 13 described later blows air, the air outside the humidifier 1 is sucked into the first ventilation path 3 through the first suction port 31. The sucked air flows through the filter housing portion 3a and the blowout air passage 3b in this order, and then blows out to the outside of the humidifying device 1 through the first air outlet 32.
An air purification chamber is provided in the vicinity of the first suction port 31 of the filter housing portion 3a (more specifically, the front side of the rear panel 10), and the air purification portion 11 is detachably accommodated in the air purification chamber. ing. The air that has flowed into the filter housing portion 3 a through the first suction port 31 passes through the air purification unit 11.

  The air purification unit 11 includes a dust collection filter 111 and a deodorization filter 112. The dust collection filter 111 is, for example, a known HEPA (High Efficiency Particulate Air) filter, and collects and removes fine dust and pollen contained in the air passing through the dust collection filter 111. The deodorizing filter 112 is made by, for example, dispersing and holding activated carbon in a nonwoven fabric, and adsorbs and removes odorous components in the air passing through the deodorizing filter 112. Therefore, the air that has passed through the air purification unit 11 is purified.

  A humidifying chamber is provided in the filter housing 3a between the air purifying unit 11 and the first blower 13, and the humidifying chamber includes a first tray 201, a humidifying filter 51, and a first tray 201 of the tray body 20 provided in the water tray 2. And the rotational drive mechanism 53 is located. A midway opening 34 is formed in the partition wall 64 of the humidifying chamber. That is, the midway opening 34 is located upstream of the first blower 13 in the ventilation direction.

  The tray main body 20 is placed on the bottom of the housing 6. For this purpose, the first tray 201 of the tray main body 20 is pushed rightward into the inside of the first ventilation path 3 (specifically, the humidifying chamber of the filter housing portion 3a) through the midway opening 34 together with the humidifying filter 51. It is done. At this time, the second tray 202 is disposed in the water supply space 60. The 1st tray 201 is pulled out from the humidification chamber of the filter accommodating part 3a to the left through the midway opening 34 with the humidification filter 51. FIG.

FIG. 3 is a rear view showing the support structure of the humidifying filter 51. In FIG. 3, illustration of the humidification filter main body 511 mentioned later is abbreviate | omitted. In addition, a part of the water receiving tray 2 is shown broken.
The humidifying filter 51 has a holding frame 510 and a humidifying filter main body 511.
The holding frame 510 has a hollow disk shape and has openings on both sides. Further, the holding frame 510 accommodates and holds the humidifying filter main body 511.

The humidifying filter main body 511 is formed by folding a sheet made of a material having water absorbability and air permeability (for example, a nonwoven fabric) into a bellows shape. For this reason, compared with the sheet | seat which is not folded at all, the contact area of the humidification filter main body 511 and the air which passes the humidification filter main body 511 is large.
On the bottom wall of the first tray 201, two support rollers 204, 204 are provided so as to be distributed on both sides in the left-right direction. The rotation shaft of each support roller 204 is arranged along the front-rear direction.

The lower portion of the humidifying filter 51 is inserted into the first tray 201 and is detachably mounted on the support rollers 204 and 204. At this time, the rotating shaft of the humidifying filter 51 is disposed in the front-rear direction, and the support rollers 204 and 204 are in rolling contact with the lower outer peripheral surface of the holding frame 510 at their respective positions. As a result, the humidifying filter 51 is supported on the upper side of the water tray 2 so as to be rotatable in the circumferential direction in a vertical posture.
The humidifying filter 51 placed on the support rollers 204 and 204 can be easily removed from the first tray 201 by lifting upward. Such attachment / detachment of the humidifying filter 51 is performed for maintenance or replacement of the humidifying filter 51, cleaning of the water tray 2, or the like.

On the outer peripheral surface of the holding frame 510, a ring gear portion 512 in which teeth are formed over the entire circumference of the holding frame 510 is integrally provided. The ring gear portion 512 is engaged with a transmission gear 531 of the rotation drive mechanism 53 described below at the upper part of the holding frame 510.
The rotational drive mechanism 53 includes a transmission gear 531 and a drive gear 532 that are attached to one surface of the base 530, and a drive motor 533 that is attached to the other surface of the base 530. It is being fixed to the appropriate position of the partition inside the housing | casing 6 with the book fixing screw 534,534, .... The drive gear 532 is fitted to the output shaft of the drive motor 533, and the rotation of the drive motor 533 is transmitted to the transmission gear 531 via the drive gear 532. As a result, the transmission gear 531 rotates.

  The meshing between the transmission gear 531 of the rotation drive mechanism 53 and the ring gear portion 512 of the holding frame 510 occurs when the humidifying filter 51 is set at a predetermined position in the first ventilation path 3. The humidifying filter 51 is supported at three points by the engagement between the transmission gear 531 and the ring gear portion 512 at the positions of the support rollers 204 and 204 and the transmission gear 531, that is, at different positions in the circumferential direction. Therefore, the humidifying filter 51 does not need to be provided with a support shaft that is rotatably supported at the center. For this reason, openings can be provided on substantially the entire surface of the front and rear surfaces of the holding frame 510 except for a minimum support portion for supporting the internal humidifying filter main body 511. As a result, a large amount of air passes through the humidifying filter body 511 without being blocked by the holding frame 510. That is, the humidification performance can be improved.

When the drive motor 533 is driven, the rotation of the transmission gear 531 is transmitted to the holding frame 510 via the ring gear portion 512. At this time, the humidifying filter 51 rotates around the center of the holding frame 510 (that is, in the circumferential direction of the humidifying filter 51).
As described above, the water at the water level L is stored in the first tray 201, and the lower portion of the rotating holding frame 510 is immersed in the stored water in the water tray 2. Since the holding frame 510 has openings on both sides, the lower part of the peripheral edge of the humidifying filter body 511 is submerged. That is, the humidifying filter main body 511 is supplied with water from the first tray 201 when a part of the humidifying filter 51 in the circumferential direction is submerged.

  At this time, the water stored in the first tray 201 is absorbed by the peripheral portion of the humidifying filter main body 511 and further sucked up from the peripheral portion to the central portion. When the holding frame 510 is continuously rotated in the circumferential direction, the peripheral edge of the humidifying filter body 511 is continuously immersed and absorbed in the circumferential direction, and the absorbed water is lifted by rotating and moving. As a result of the above, water efficiently spreads throughout the humidifying filter body 511. In other words, the humidification filter main body 511 rotates to promote water absorption of the humidification filter main body 511.

  The air that has passed through the air purification unit 11 then passes through the humidifying filter 51. When the humidifying filter 51 is rotating, the air that has passed through the humidifying filter 51 sufficiently absorbs moisture. On the other hand, when the humidifying filter 51 is not rotating, the air that has passed through the humidifying filter 51 hardly absorbs moisture. Accordingly, when both air cleaning and air humidification are performed, the rotation drive mechanism 53 operates to rotate the humidification filter 51. However, when air humidification is not performed only by air cleaning, the rotation drive mechanism 53 does not operate. Below, the case where both air purification and air humidification are performed is demonstrated.

The 1st air blower 13 is distribute | arranged to the boundary part of the filter accommodating part 3a and the blowing wind path 3b.
The first blower 13 uses a sirocco fan (multi-blade impeller), and includes an electric fan motor 131 and a fan 132.
The fan motor 131 is fixed inside the housing 6 by a support portion (not shown). The fan 132 is fixed to the output shaft of the fan motor 131. The fan 132 is rotated by driving of the fan motor 131, and air is blown by the rotation of the fan 132.
In the filter housing portion 3a, air flows substantially horizontally from the rear side to the front side, and in the blowout air passage 3b, air flows from the front lower side to the rear upper side in an inclined manner.

A louver 33 is disposed at the first air outlet 32. The inner peripheral surface of the blowout air passage 3b and the louver 33 regulate the direction in which air flows so that the air blown out through the first blowout port 32 is likely to rise along the wall W.
With respect to the first ventilation path 3 as described above, air flows as indicated by solid white arrows.
More specifically, air is sucked into the filter housing portion 3 a from the room through the first suction port 31. The sucked air flows forward through the filter housing 3a. At this time, the sucked air is purified and humidified by passing through the air purifying unit 11 and the humidifying filter 51. Hereinafter, the air purified and humidified by the air purification unit 11 and the humidifying filter 51 is referred to as purified humidified air.

Next, the purified humidified air flows from the filter housing portion 3a to the blowing air passage 3b. In the blowout air passage 3b, the purified humidified air flows in the rear upper direction, and finally blows out into the room through the first air outlet 32.
The purified humidified air blown into the room is blown onto the wall W, further rises along the wall W, then moves along the ceiling to the wall facing the wall W, and further descends along this wall. It moves to the wall W along the floor F. That is, the purified humidified air circulates throughout the room.

Next, the second ventilation path 4 will be described with reference to FIG.
The 2nd ventilation path 4 has the suction chamber 4a and the blowing chamber 4b which are mutually connected. The second ventilation path 4 is provided with a second suction port 41 and a second air outlet 42.
The second suction port 41 opens in the front cover 61 of the housing 6, and the outside of the humidifier 1 and the suction chamber 4 a communicate with each other through the second suction port 41.
The second air outlet 42 opens at a boundary portion between the front cover 61 and the top cover 62 of the housing 6, and the air outlet 4 b communicates with the outside of the humidifier 1 through the second air outlet 42. doing.

When the second blower 14 described later blows air, the air outside the humidifier 1 is sucked into the second ventilation path 4 through the second suction port 41. The sucked air flows through the suction chamber 4a and the blowout chamber 4b in this order, and then blows out to the outside of the humidifier 1 through the second blowout port 42.
An air filter 40 is detachably disposed in the second suction port 41. The air filter 40 collects and removes coarse dust contained in the air flowing into the suction chamber 4a through the second suction port 41. The size of dust removed by the air filter 40 is approximately the same as the size of dust removed by the pre-filter of the rear panel 10.

A second blower 14 is disposed at a boundary portion between the suction chamber 4a and the blowout chamber 4b.
The second blower 14 uses a cross-flow fan (cross-flow impeller), and is an electric fan motor fixed to the inside of the housing 6 by a support portion (not shown) and a fan fixed to the output shaft of the fan motor. And. The fan of the 2nd air blower 14 rotates by the drive of a fan motor, and air is ventilated when a fan rotates.

In the middle of the blowout chamber 4b, an ion generator 12 is disposed.
The ion generation unit 12 includes an ion generation electrode (not shown) and a counter electrode disposed to face the ion generation electrode, and is configured to generate positive and negative ions by corona discharge. The ion generating electrode is exposed to the blowing chamber 4b, and the generated positive and negative ions float in the air flowing through the blowing chamber 4b.

In the suction chamber 4a, the air flows from the front lower side to the rear upper side, and in the blowing chamber 4b, the air flows in the front upper side.
A louver 43 is disposed at the second outlet 42. The inner peripheral surface of the blowout chamber 4b and the louver 43 regulate the direction in which air flows so that the air blown out through the second blowout port 42 can easily reach the central portion of the room.
Positive and negative ions released into the room together with the air blown out through the second air outlet 42 kill or inactivate fungi, viruses, allergens, etc., and cause a malodor (for example, an organic compound such as acetaldehyde) ).
With respect to the second ventilation path 4 as described above, air flows as indicated by broken arrows.

More specifically, air is sucked into the suction chamber 4a from the room through the second suction port 41. The sucked air flows through the suction chamber 4a in the rear upper direction and then flows through the blowing chamber 4b in the front upper direction. The air flowing through the blowing chamber 4b becomes air containing ions generated by the ion generator 12 (hereinafter referred to as ion-containing air). Then, the ion-containing air blows out into the room through the second air outlet 42.
The ion-containing air blown into the room is directed to the central part of the room. As a result, the ion-containing air easily reaches the central portion of the room.

Next, the configuration of the water tray 2 and the partition plate 7 will be described in detail.
4 to 7 are perspective views showing configurations of the water tray 2 and the partition plate 7. FIG. 4 is a perspective view seen from the first tray 201 side, and shows a case where a later-described tray lid 24 is not attached. FIG. 5 is a perspective view seen from the second tray 202 side, and shows a case where the tray cover 24 is not attached, as in FIG. FIG. 6 is a perspective view seen from the first tray 201 side as in FIG. 4, but shows a case where the tray lid 24 is attached. FIG. 7 is a perspective view as seen from the second tray 202 side as in FIG. 5, and shows the case where the tray lid 24 is attached as in FIG.

FIG. 8 is a side view showing the configuration of the water tray 2 and the partition plate 7, and shows a case when viewed from the first tray 201 side.
9 and 10 are enlarged perspective views corresponding to FIGS. 4 and 6, and show the periphery of the partition plate 7.
11 is a cross-sectional view taken along line XI-XI in FIG.
The water tray 2 further includes a tray lid 24 and a lid side engaging portion 25.

The tray lid 24 is a lid for the first tray 201. Specifically, the tray cover 24 detachably covers the water surface of the water stored in the first tray 201 other than the portion where the humidifying filter 51 can be submerged. For this purpose, the tray lid 24 has a plate shape in which an insertion hole 241 is formed at the center.
A mounting table 205 on which the tray cover 24 is detachably mounted is provided at the center in the vertical direction of the inner surface of the peripheral wall of the first tray 201. The arrangement position of the tray lid 24 mounted on the mounting table 205 is sufficiently higher than the water level L.
The tray lid 24 mounted on the mounting table 205 is suppressed from being unnecessarily detached from the water tray 2 due to its own weight. The tray lid 24 may be configured to be detachably locked to the upper part of the peripheral wall of the first tray 201.

When the humidifying filter 51 is set in the water tray 2, it is placed on the support rollers 204, 204 after being inserted through the insertion hole 241. At this time, the peripheral edge portion of the insertion hole 241 and the humidification filter 51 are separated by an appropriate length. Therefore, the tray lid 24 does not hinder the rotation or water absorption of the humidifying filter 51.
By the way, a sufficient gap exists between the humidification filter 51 and the inner wall of the first ventilation path 3. This is because if the humidifying filter 51 and the inner wall of the first ventilation path 3 are in close contact with each other, the rotation of the humidifying filter 51 is hindered. For this reason, a part of the air flowing through the filter housing portion 3a may bypass the humidifying filter 51 and detour.

If the tray lid 24 is not present, the air that bypasses the humidifying filter 51 touches the water surface to generate a wave on the water surface, and water droplets are wound up. And the problem that the air wound up is scattered to the exterior of the water receiving tray 2 arises.
On the other hand, the tray lid 24 prevents the air bypassing the humidifying filter 51 from touching the water surface. For this reason, air does not touch the water surface and a wave is generated on the water surface, and water drops are not rolled up. Even if the water droplet is rolled up, the scattered water droplet adheres to the tray lid 24 or is reflected by the tray lid 24 and falls to the water surface.
A convex lid side engaging portion 25 is integrally formed on the left side portion of the tray lid 24. The lid side engaging portion 25 is an engaging claw that engages with an engaging hole 74 described later of the partition plate 7 with play.

The water tray 2 further has a partition wall 21 and a wall side engaging portion 22.
The partition wall 21 partitions the inside of the tray body 20 into a first tray 201 that is the side disposed in the first ventilation path 3 and a second tray 202 that is the side disposed in the water supply space 60 and supplied with water. To do. For this purpose, the partition wall 21 is integrally formed at the boundary between the first tray 201 and the second tray 202 inside the tray body 20.
A water passage hole 23 is formed in the lowermost part of the partition wall 21. Since the formation position of the water passage hole 23 is sufficiently lower than the water level L, the water passage hole 23 is completely submerged when the water is stored in the tray body 20.

A convex wall-side engagement portion 22 is integrally formed on the upper surface of the partition wall 21 on the first tray 201 side. The wall-side engagement portion 22 is an engagement claw that engages with the engagement hole 74 of the partition plate 7 with play.
The partition plate 7 has a play in at least the left-right direction (that is, the direction intersecting the partition plate 7) and is detachably attached to the water tray 2.
The partition plate 7 has a rectangular shape and is arranged on the upper portion of the water tray 2 in a vertical posture along the front-rear direction and the vertical direction (that is, orthogonal to the left-right direction). At this time, the base end part 71 and the front-end | tip part 72 of the partition plate 7 are a lower end part and an upper end part.

The base end portion 71 is U-shaped in plan view, and has a front portion, a rear portion, and a right side portion. The front portion, the rear portion, and the right side portion of the base end portion 71 are disposed in close contact with the upper end portions of the peripheral walls 20 a and 20 b that are continuous with the partition wall 21 of the second tray 202 and the upper end portion of the partition wall 21.
The base end portion 71 is integrally provided with a hanging portion 73. When the base end portion 71 is attached to the water tray 2, the hanging portion 73 is disposed inside the first tray 201 along the partition wall 21.

The hanging portion 73 is provided with an engaging hole 74. The wall-side engagement portion 22 of the partition wall 21 and the lid-side engagement portion 25 of the tray lid 24 are inserted into the engagement holes 74 from opposite directions. At this time, the wall-side engaging portion 22 (and the lid-side engaging portion 25) are engaged with the upper side (and the lower side) of the engaging hole 74 so as to be detachable at least in the left-right direction. ing. Further, the engagement hole 74 is covered with the partition wall 21 from the second tray 202 side.
Here, attachment of the partition plate 7 and the tray lid 24 to the tray body 20 will be described.

The operator places the base end portion 71 of the partition plate 7 on the upper end portions of the partition wall 21 and the peripheral walls 20 a and 20 b of the tray body 20. At this time, the operator inserts the wall side engaging portion 22 of the partition wall 21 into the engaging hole 74 of the partition plate 7 from the left side. As a result, the wall side engaging portion 22 is engaged with the upper inner surface of the engaging hole 74 with play.
Next, the operator places the tray lid 24 on the placing table 205 of the tray body 20. At this time, the operator inserts the lid side engaging portion 25 of the tray lid 24 into the engaging hole 74 of the partition plate 7 from the right side. As a result, the lid side engaging portion 25 is engaged with the lower inner surface of the engaging hole 74 with play.
The engagement between the wall-side engagement portion 22 and the lid-side engagement portion 25 and the engagement hole 74 is not naturally released unless the operator removes the tray lid 24.

If the base end portion 71 is merely placed on the tray main body 20, the partition plate 7 easily falls off from the upper portion of the tray main body 20 unnecessarily. However, in the present embodiment, the wall side engaging portion 22 and the lid side engaging portion 25 engage with the engaging holes 74 from both the left and right sides, so that unnecessary separation of the partition plate 7 is suppressed.
On the other hand, since the engagement between the wall side engaging portion 22 and the lid side engaging portion 25 and the engaging hole 74 has play, the operator can easily release it manually.
If the tray lid 24 is removed from the tray body 20 and the partition plate 7 is further removed, the operator can easily wash the tray body 20, the tray lid 24, and the partition plate 7 respectively.

Next, the effect of the partition plate 7 will be described.
FIG. 12 is a schematic cross-sectional view for explaining the state of the partition plate 7 during non-air blowing, and FIG. 13 is a schematic cross-sectional view for explaining the state of the partition plate 7 during air blowing.
First, the attachment of the water tray 2 and the partition plate 7 to the housing 6 will be described with reference to FIGS. 1, 11, and 12.

The operator attaches the water tray 2 to which the humidifying filter 51 and the partition plate 7 are attached to the housing 6. At this time, the humidifying filter 51, the first tray 201 of the water tray 2, the tray lid 24, the hanging portion 73 of the partition plate 7, etc. are arranged in the filter housing portion 3 a of the first ventilation path 3 through the midway opening 34. Is done. Further, the second tray 202 of the water receiving tray 2, the base end portion 71 and the front end portion 72 of the partition plate 7, etc. are arranged in the water supply space 60.
As a result, as shown in FIGS. 11 and 12, the midway opening 34 is closed by the partition plate 7, the partition wall 21, and the tray body 20.

At this time, it is desirable that the front end portion 72 of the partition plate 7 and the two sides connected to the front end portion 72 are in close contact with the opening edge of the midway opening 34 from the water supply space 60 side.
However, due to a slight dimensional error of each part of the humidifier 1, a positional deviation when the partition plate 7 is attached to the tray body 20, a positional deviation when the tray body 20 is attached to the housing 6, or the like. As shown in FIG. 12, a midway gap G may occur between the opening edge of the midway opening 34 and the partition plate 7.

Here, the state of the partition plate 7 during non-air blowing will be described with reference to FIG.
When the 1st air blower 13 is not blowing, the air pressure of the 1st ventilation path 3 and the water supply space 60 is all equal to atmospheric pressure. For this reason, there is no air flow caused by the pressure difference between the first ventilation path 3 and the water supply space 60 via the midway gap G. Since the case where the 1st air blower 13 is not blowing is the case where the humidification device 1 is not operating, there is no particular problem even if the midway gap G exists.

Next, the state of the partition plate 7 during blowing will be described with reference to FIGS. 2 and 13.
When the first blower 13 is blowing air, that is, when the humidifying device 1 is operating, the air pressure in the filter housing portion 3a of the first ventilation path 3 becomes negative when the air pressure in the water supply space 60 is used as a reference. This is because the first blower 13 sucks air from the filter housing portion 3a side and blows it out to the blowout air passage 3b side.

At this time, a force that sucks the partition plate 7 toward the first ventilation path 3 (that is, the right side) acts on the partition plate 7 due to the negative pressure. The partition plate 7 has play in at least the left and right direction and is attached to the water tray 2 (that is, it is not fixed to the water tray 2 at least in the left and right direction). The entire partition plate 7 slides easily in the right direction (that is, the direction of the white arrow in FIG. 13). Then, the leading end 72 of the partition plate 7 and the two sides connected to the leading end 72 are in close contact with the opening edge of the midway opening 34 from the water supply space 60 side.
That is, the midway gap G that existed during non-air blowing disappears naturally during air blowing. And as long as the 1st air blower 13 is blowing, there is no possibility that the middle space | gap G may arise again.

When the humidifier is operating, the water passage hole 23 is submerged. Further, the base end portion 71 of the partition plate 7 and the partition wall 21 and the peripheral walls 20 a and 20 b of the tray body 20 are sealed by the weight of the partition plate 7. Further, the peripheral wall and bottom wall of the tray body 20 and the opening edge of the midway opening 34 are sealed by the weight of the water tray 2.
As a result, there is no air flow caused by the pressure difference between the first ventilation path 3 and the water supply space 60.

The humidifier 1 as described above can suppress the generation of noise due to the midway gap G with a simple configuration. Moreover, it can suppress that the air which has not passed the air purification | cleaning part 11 flows through the 1st ventilation path 3. FIG.
First blower 13, water tray 2, tray body 20, first tray 201, second tray 202, humidification filter 51, first ventilation path 3, first suction port 31, first blowout port 32, of the present embodiment. The midway opening 34, the tray lid 24, the water supply space 60, and the base end portion 71 are arranged and supplied with water from the air blower, the water tank, the water tank body, the side of the air passage, and the outside of the air passage in the embodiment of the present invention. Functions as a filter side, a filter, a ventilation path, a suction port, an outlet, an opening, a covering portion, the outside of the ventilation path, and one end of a partition plate.

The air purification unit 11 is not limited to the one having the dust collection filter 111 and the deodorization filter 112. For example, the air purification unit 11 may be configured to purify air by passing it through water.
By the way, the 2nd ventilation path 4 is not provided in the conventional common humidifier. Moreover, the ion generating part 12 may be arranged in the vicinity of the 1st blower outlet 32. FIG. Even if it is such a structure, the effect of this invention can be acquired by providing the water receiving tray 2 and the partition plate 7 like this Embodiment.
Although the humidifier 1 of this embodiment is a structure which arrange | positions a part of water tray 2 inside the 1st ventilation path 3, the humidification apparatus in embodiment of this invention is the whole ventilation tank of a water tank. The structure arrange | positioned inside may be sufficient.
