Abstract

The present invention provides an air cleaner with a function of humidification. At a state that the humidification operation is not performed (the rotation of a humification unit (20) is stopped), a control part (38) detects a driving state of a fan (17). According to the detected driving state, the humification unit (20) is rotated for at least one circle with a preset time interval confirmed relatively to the driving state according to the detected driving state. Thus, even at a state that the humidification operation is not performed, the humification unit (20) is wholly humidified always by the water of a water container (22) (to a state with water drops). Thus the humification unit (20) does not change to a semi-dry state. As a result, the generation of unfavorable stink from the humification unit (20) along with the semi-dry state of the humification unit (20) at a state that the humification unit is stopped can be prevented.

(overall structure of air purifier)

Fig. 1 is the right view of air purifier 1, and its part illustrates with the cross section.

As shown in Figure 1, as the body housing 2 of the framework of air purifier 1, be the thin hollow shape that is roughly cuboid of lengthwise and fore-and-aft direction (in Fig. 1, being left and right directions).Body housing 2 is by the front casing 3 that becomes first half roughly and become roughly that the rear casing 4 of latter half forms its outline.At this, the front side has identical meaning respectively with face side, rear side and rear side, fore-and-aft direction and general horizontal direction.In addition, side is the right side in front in Fig. 1, and the inboard is the left side.

End face at front casing 3 is provided with operation panel 5.Can control the operation of air purifier 1 by operating in the operated key (not shown) that is provided with on the operation panel 5, the display part (not shown) that is provided with on operation panel 5 shows the service condition and the state of air purifier 1.

The position of leaning on slightly in the front of front casing 3 is formed with inlet 6.The internal communication of this inlet 6 and front casing 3.End face, left surface and right flank at rear casing 4 are formed with outlet 7 respectively.The internal communication of these outlets 7 and rear casing 4.Export 7 places at each and be provided with grid 8.Air purifier 1 is discharged (with reference to the arrow of heavy line) with cleaned air passes from exporting 7 again from 6 suction air and the purification of entering the mouth.

Between front casing 3 and rear casing 4, be provided with the spaced walls 9 of extending at above-below direction, divide the inside of front casing 3 and the inside of rear casing 4 by this spaced walls 9.Lower portion in spaced walls 9 is formed with intercommunicating pore 10, by this intercommunicating pore 10 inside of front casing 3 and the inside of rear casing 4 is interconnected.

Particularly, the inside of front casing 3 by partition wall 11 be divided into first space 12 of inlet 6 upsides that are communicated with and with second space 13 of the 6 disconnected downsides that enter the mouth.The lower end frame portion that constitutes intercommunicating pore 10 on partition wall 11 and the spaced walls 9 is mutually continuous, is connected to the antetheca of front casing 3, thereby cuts off between first space 12 and second space 13 to top, oblique front side (among Fig. 1 for tiltedly top, left side) extension.And intercommunicating pore 10 is communicated with the inside (the 3rd space 14) of first space 12 and rear casing 4, and second space 13 and the 3rd space 14 are communicated with.

In the inside of body housing 2, be formed with the air flow channel 15 (with reference to the heavy line arrow) that inlet 6 and inlet 7 are communicated with.At the described intercommunicating pore 10 of being provided with of air flow channel 15 midway.

For body housing 2, first space 12 of front casing 3 inside, particularly be midway, at the filter 16 that possesses from rear side (Fig. 1 is the right side) and inlet 16 positions of facing as air cleaning member at air flow channel 15.Possesses fan 17 at the rear side of the filter 16 at 12 places, first space as blowing unit.

The rectangular shape that filter 16 is long for above-below direction and fore-and-aft direction is thin.Constitute filter 16 by stacked multiple filter membrane, this filter 16 not only can be caught bigger dust contained in the air, and even for example the very tiny dust such as particle in pollen, the flue gas also can catch.

Fan 17 for example is a Sirocco fan, drives rotation by the motor (not shown) and produces attraction, sucks the air of front side from the inboard, (is meant outer side-lower herein) more laterally and discharges.

For this air purifier 1, if drive fan 17, the attraction that the air outside of air purifier 1 can be produced by fan 17 6 is incorporated in first space 12 of front casing 3 from entering the mouth, and becomes air stream.And shown in the arrow of heavy line, this air (air stream) flows through air flow circuit 15, and dust, stink composition are removed by filter 16 in the way therein, thereby realizes air cleaning.In other words, filter 16 will flow to the downstream of air flow channel 15 after 6 air cleanings of introducing that enter the mouth.Air after being cleaned (hereinafter only being called " air ") is discharged downwards by fan 17 and is continued to flow in air flow channel 15, sends into to the inside (the 3rd space 14) of rear casing 4 from the intercommunicating pore 10 of spaced walls 9, finally is sent to outlet 7.

Like this, the air that flows through air flow channel 15 is discharged to the outside of air purifier 1 from each outlet 7.(after the being cleaned) air that is discharged to machine exterior will arrive each corner of the outside (for example indoor) of air purifier 1, at large to whole indoor the purification.

And this air purifier 1 is because of having above-mentioned humidification function, so for flow air in the air flow channel 15 is carried out humidification, and humidifying unit 20 is equipped with in the 3rd space 14 of rear casing 4.

(overall structure of humidifying unit)

Air after 20 pairs of processes of humidifying unit filter 16 is cleaned carries out humidification.Whereby, from exporting 7, to replenish indoor moisture to the indoor air that contains moisture of emitting.

With humidifying unit 20 associated, water tank 21 mainly is set in body housing 2 and holds water ware 22 as aqua storage tank.

Water tank 21 is configured in second space 13 in the front casing 3, is that the width (perpendicular to the direction of Fig. 1 paper) that water can be accumulated in inside is gone up long hollow body structure.

Be formed with the spilled water hole 23 that opens and closes by the valve body (not shown) in the bottom of water tank 21.Water tank 21 is fixed on ratio inlet 6 on the antetheca of front casing 3 by the parts (being called front cover body 24) of downside by screw etc.At this, front cover body 24 can separate from front casing 3.Therefore, water tank 21 and front cover body 24 can become one, and load and unload from its face side with respect to front casing 3 (body housing 2).Whereby, can be water tank 21 moisturizings.

Hold water ware 22 and be housed in bottom in the body housing 2, and have the size (degree of depth) of the bottom separately that can accommodate humidifying unit 20 and water tank 21.Particularly, be provided with demarcation strip 25 in the bottom of holding water ware 2, the inside that will hold water ware 22 by this demarcation strip 25 is divided into front and back two parts.In the inside of holding water ware 22, than the bottom of the zone of demarcation strip 25 forward sides (being the left side in Fig. 1) (zone, front side 22A) configuration water tank 21, in the bottom that disposes humidifying unit 20 than demarcation strip 25 in Fig. 1 by the zone (posterior region 22B) of rear side (be the right side).That is to say that zone, the front side 22A that accommodates water tank 21 bottoms in holding water ware 22 is configured in second space 13 of front casing 3, the posterior region 22B that accommodates humidifying unit 20 bottoms is configured in the 3rd space 14 of rear casing 4.

At this, below intercommunicating pore 10, forming through hole 26 on the spaced walls 9, the size of this through hole 26 just can be separated plate 25 and block.This through hole 26 is communicated with second space 13 of front casing 3 and the 3rd space 14 of rear casing 4.Usually under the state, through hole 26 on fore-and-aft direction with demarcation strip 25 consistent (coincidence), and be separated plate 25 and seamlessly block from rear side.

In the bottom of demarcation strip 25, connect the intercommunicating pore 27 of demarcation strip 25 before and after being formed with, by this intercommunicating pore 27, zone, front side 22A is connected with posterior region 22B.

If water tank 21 is housed in the front side zone 22A that holds water ware 22, projection 28 jack-up that projected upwards by self-supporting water ware 22 bottoms of the above-mentioned valve body (not shown) of water tank 21 bottoms then, and open the spilled water hole 23 of water tank 21.Whereby, the water in the water tank 21 is discharged to territory, region of the front side 22A from spilled water hole 23, flows to posterior region 22B from intercommunicating pore 27, thereby accumulates in posterior region 22B.

And, reach predetermined water level if accumulate at posterior region 22B water, in its process, water can come and go between front side zone 22A and posterior region 22B by intercommunicating pore 27, and the result makes zone, front side 22A and posterior region 22B to wait water level link to each other (with reference to water surface S among the figure).At this moment, intercommunicating pore 27 is positioned at the below of water surface S, by the water thorough impregnation.In addition, as mentioned above, the through hole 26 of space bar 9 is held the demarcation strip 25 of water ware 22 and is blocked.Therefore, air can not come and go between front side zone 22A and posterior region 22B by intercommunicating pore 27.Whereby, the air in first space 12 of front casing 3 and the inside of rear casing 4 (the 3rd space 14) can not leak into second space 13, so can not leak into second space 13 in air flow channel 15 flow air yet.

In addition, humidifying unit 20 is configured in air flow channel 15 (with reference to the arrow of heavy line) midway, and described air flow channel 15 is to make air pass through the runners that filter 16 and fan 17 flow towards each outlet 7.Therefore, the air-flow (air stream) that is filtered the air of device 16 purifications necessarily passes through humidifying unit 20.

Humidifying unit 20 roughly is disc, and has the upwardly extending central shaft in front and back.This humidifying unit 20 mainly comprises the header board 30 and the back plate 31 of humidification member 32, front and back configuration arranged spaced apart.Header board 30 is the annular plates (with reference to aftermentioned Fig. 6) with neighboring and inner periphery.Back plate 31 is a circular plate shape.The central shaft separately of header board 30 and back plate 31 extends along fore-and-aft direction, and always observes from front and back, and these central shafts overlap.The external diameter of the external diameter of header board 30 and back plate 31 is roughly the same.

At this, humidifying unit 20 possesses a plurality of beam parts 33.Each beam parts 33 are upwardly extending bar-shaped in front and back.These beam parts 33 are to separate arrangement with about equally interval on the circumferencial direction at center at the central shaft with humidifying unit 20, and with its integral body (with reference to Fig. 6) in the form of a ring.Each beam parts 33 be erected at header board 30 outer periphery edge portion and the back plate 31 outer periphery edge portion between.Whereby, header board 30 and back plate 31 all form integrated with beam parts 33 with above-mentioned at the isolated state of fore-and-aft direction.

At this, be called as supporter 34 by the aggregate of incorporate header board 30, back plate 31 and beam parts 33.Than the part of back plate 31 forward sides,, and form ring-type (with reference to Fig. 6) in the supporter 34 by the header board 30 and the whole a plurality of beam parts 33 that become ring-type of annular plate structure.On supporter 34, the part that is marked off by its inner circumference edge (particularly, the inner periphery of header board 30 and a plurality of beam parts 33) is called interior space 35.

And on supporter 34, above-mentioned humidification member 32 is reeled along the neighboring (particularly, neighboring and a plurality of beam parts 33 of header board 30 and back plate 31) of supporter 34.As described below, humidification member 32 strip material (with reference to following Fig. 4 (b)) that cloth material with water imbibition and retractility forms of serving as reasons, but under the state that is wound onto supporter 34, become ring-type (with reference to following Fig. 5 A).

Described humidification member 20 is that the rotatable mode in center supports with axle 37, and this 37 forwards extends from the part (being called rear cover body 36) of the rear wall of rear casing 4 along general horizontal direction and the center of circle by header board 30 and back plate 31.Under this state, the bottom of humidifying unit 20 (neighboring of supporter 34 and the bottom that is wound on the humidification member 32 on the supporter 34) is immersed in the water that the posterior region 22B that holds the water ware accumulates predetermined water level (with reference to water surface S).

And, as mentioned above, the air that purifies at filter 16 continues to flow in air flow channel 15 and during by humidifying unit 20, and humidifying unit 20 accepts to be rotated from the driving force of not shown motor etc. (with reference to the line of the single-point shown in Fig. 1 arrow 1).By humidifying unit 20 rotation, humidification member 32 is with supporter 34 rotations, and along with this be rotated in the state in the water that immerses posterior region 22B and the state of from this water, mentioning between move.Further, humidification member 32 is when being in the state of mentioning from water, and it is exposed in the air-flow (with reference to the heavy line among Fig. 1) of cleaned air passes.Particularly, on humidification member 32, be immersed in the water of posterior region 22B and wetted part, before humidifying unit 20 is finished a circle rotation during, all be exposed in the air flow channel 15 in the cleaned air passes air-flow.Consequently, attached to the air-flow humidification of the moisture on the humidification member 32, discharge towards the direction of regulation from exporting 7 with these air, and help the indoor humidification that carries out to cleaned air passes.In addition, on the supporter 34 accompanying moisture also to air wetting.

At this, because the beam parts 33 of at least a portion are the hollow-core construction (not shown), so in the rotation of following humidifying unit 20 and during the water of the beam parts 33 of hollow-core construction by posterior region 22B, thereby the beam parts 33 of hollow-core construction can innerly drain out water by the water of posterior region 22B being accumulated in it.With the same attached to the water on the humidification member 32, the water that is drained out by beam parts 33 also carries out humidification to air.The water that these beam parts 33 are drained out, for example: under the state in accumulating in these beam parts 33 to air wetting; From beam parts 33 unrestrained and during attached to supporter 34 surfaces to air wetting; Thereby make with humidification work carry out and the humidification ability of the wetting once more recovery of the humidification member 32 that becomes dry humidification member 32.

In addition, the mainly consideration that waits the regular maintenance of this class for the cleaning (removals of fouling products such as incrustation scale) and the replacing of humidification member 32, axle 7, the rear cover body 36 of the humidifying unit 20 that humidifying unit 20 can rotate freely with support and hold water ware 22 and become one, with respect to body housing 2 from its back side one side loading and unloading.

(preventing dry control)

For this air purifier 1, as mentioned above, rotation along with humidifying unit 20, humidification member 32 in the water that immerses posterior region 22B state and the state of from this water, mentioning between move, when from water, mentioning, soaked in the air-flow of the air that part in the water of posterior region 22B is exposed to air flow channel 15, thereby 32 pairs of air of described humidification member carry out humidification.The operation of in this way air being carried out humidification with air purifier 1 is called the humidification operation.

For air purifier 1, if stop the rotation of humidifying unit 20, the part that then is dipped in the humidification member 32 in the water of posterior region 22B can not be exposed in the air draught of air flow channel 15 again, thereby can stop the humidification operation.

At this, for air purifier 1, be in reason such as desired value sometimes because of indoor humidity and stop humidification operation (not carrying out the humidification operation) and only need to make fan 17 rotations that air outside is purified the operation (air cleaning operation) that machine exterior are discharged in the back at filter 16.For this situation, because the cleaned air passes air flow channel 15 of flowing through under the state that humidifying unit 20 is stopped the rotation, so these air blow the part (part of water level S upside) in the water that does not immerse posterior region 22B on humidification member 32, thereby this part begins drying gradually from the state of wetting (degree that will drip).

If humidification member 32 beginning is dry, then can be from growing assorted bacterium attached to the incrustation scale the moisture on the humidification member 32, and these assorted bacterium sometimes can generation be made us uncomfortable foul smell.Particularly, because humidification member 32 is formed by the cloth material as described above, so for situation about being formed by resin, its dehydration property is poor, correspondingly its inside more is easy to generate assorted bacterium.

And, if the stink that produces from humidification member 32 is discharged to machine exterior with the flow through air of air flow channel 15 of air cleaning operation, may floats and be dispersed in the indoor user of making uncomfortable feeling is arranged.

At this, for air purifier 1, change the rotary speed of fan 17 by the operated key (not shown) of operation aforesaid operations plate 5, can be (promptly to the air output of air flow channel 15, inlet 6 air imbibed quantity also exports 7 air discharge rate) carry out strong (about 3 cubic meters per minute), in (about 1.5 cubic meters per minute), weak (about 0.6 cubic meters per minute) three grades of adjustings.

And, be driven in rotation and make under the state (carrying out the state of air cleaning operation) that air flows in air flow channel 15 at fan 17, stop the rotation (humidification operation) of humidifying unit 20.So, as shown in Figure 2, under the air output of air flow channel 15 is strong situation, after the rotation that stops humidifying unit 20 begins to pass through about 2.5 minutes, humidification member 32 beginnings of humidifying unit 20 are dry, be accompanied by this kind situation, shown in heavy line, the odor strength of the stink that produces from humidification member 32 raise (it is heavier that stink becomes).Begin through about 5 minutes from the rotation that stops humidifying unit 20, humidification member 32 becomes half-dried state, and odor strength reaches maximum (stink is the heaviest).Then, further dry at humidification member 32 from half-dried state, and feasible the movable slow of bacterium of mixing, the intensity of stink reduces gradually whereby.Begin through after about 7 minutes from the rotation that stops humidifying unit 20, humidification member 32 bone dries, odor strength return to the value of humidification member 32 beginnings before dry, and this humidification member 32 no longer sends and makes us uncomfortable stink.

On the other hand, under the situation in the air output of air flow channel 15 is, shown in thick dashed line, begin process in the time of about 5 minutes from the rotation that stops humidifying unit 20, odor strength begins rise (begin generation from humidifying unit 20 and make us uncomfortable stink).Under the air output of air flow channel 15 was weak situation, shown in thick dotted line, when the rotation that stops humidifying unit 20 began through about 8 minutes, the intensity of stink began to rise.

And odor strength as shown in Figure 2 is the variation of process in time, is that the harsh environment that humidity is about 30% around, the 32 the fastest easy generations of humidification member are half-dried takes place down; Under humidity surpassed 30% common environment, the intensity of above-mentioned stink began rising than the situation shown in Fig. 2 late a few minutes.

Like this, for air purifier 1,, then begin just may give off soon to make us uncomfortable stink from stopping the humidification operation if stop humidification operation carrying out air cleaning operation.Particularly, air output is strong more, can make us uncomfortable stink in stage discharge early more.

Therefore, the control part 38 comprise microcomputer (detecting unit and prevent drying unit, with reference to Fig. 1) is set in body housing 2.Control part 38 is by the rotation (being the driving that makes the not shown motor of fan 17 rotations strictly speaking) of control fan 17, the rotation (being the driving that makes the not shown motor of wet unit 20 rotations strictly speaking) of humidifying unit 20, humidifying unit 20 (especially, the humidification member 32) is prevented dry control.

Fig. 3 is used to illustrate the flow chart that prevents dry control.

Particularly, with reference to Fig. 3, at first, operate under the situation of opening (fan 17 is rotating, and is "Yes" at step S1) in above-mentioned air cleaning, control part 38 confirms that whether the humidification operation is for opening (step S2).

Open (is "Yes" at step S2) if humidification operates to, control part 38 is opened the rotation of humidifying unit 20, makes humidifying unit 20 rotations (step S3).Whereby, carry out the humidification operation.

At this, be provided with the humidity sensor (not shown) of measuring (indoor) humidity outside the machine on air purifier 1, controller 38 confirms in the humidification testing result according to the humidity sensor (not shown) in service whether indoor humidity has reached setting humidity (step S4).If indoor humidity has reached setting humidity (is "Yes" at step S4), control part 38 stops the rotation of humidifying unit 20 and stops humidification operation (step S5).

In addition, (is "No" in step 2) do not opened in the humidification operation, control part 38 is not carrying out under the state of humidification operation, waits the driving condition that detects fan 17 from the rotary speed of fan 17, and confirms the air output (step S6) of (detection) air flow channel 15 according to this driving condition.Particularly, control part 38 is about the driving condition of fan 17, detect comprise air output be above-mentioned strong, in, weak various states.

Air output is under the situation of strong (with reference to Fig. 2), operate at humidification under the state of pass, (or air cleaning operates to the state opened down and the moment that the humidification operation is closed from beginning to carry out to carve in the air cleaning operation, be referred to as " benchmark constantly " below) rise whenever through 2 minutes, control part 38 just makes humidifying unit 20 revolve turn around (step S7).Whereby, under aforesaid air output is strong state, stop the rotation from humidifying unit 20 and to begin through about 2.5 minutes, before the humidification member 32 of humidifying unit 20 (immersing the part in the water of the posterior region 22B hold water ware 22) the beginning drying, part in the water that does not immerse the posterior region 22B that holds water ware 22 of the humidification member of humidifying unit 20 is immersed in the water of the posterior region 22B that holds water ware 22, and the humidification member 32 whole wetting degree of dripping that reach.

At this, control part 38 just made humidifying unit 20 revolve in per two minutes and turns around, so humidification member 32 be in the time will beginning drying, and humidification member 32 is whole wetting before drying, the result is under air output is strong state, keeps humidification member 32 whole wetting states all the time.

In addition, under the situation in air output is (with reference to Fig. 2), control part 38 begins whenever just to make humidifying unit 20 revolve turn around (step S8) through 4 minutes from benchmark constantly.Whereby, as mentioned above, under the state in air output is after the rotation that stops humidifying unit 20 through about 5 minutes, before the humidification member 32 beginning dryings of humidifying unit 20, part in the water that does not immerse the posterior region 22B that holds water ware 22 on the humidification member 32 of humidifying unit 20 is immersed in the water of the posterior region 22B that holds water ware 22, the humidification member 32 whole wetting degree of dripping that reach.Whereby, under the state in air quantity is, keep humidification member 32 whole wetting states all the time.

In addition, be under the weak situation (with reference to Fig. 2) at air output, control part 38 begins whenever just to make humidifying unit 20 revolve the (step 9) that turns around through 7 minutes from benchmark constantly.Whereby, as mentioned above, air output be under the weak state after the rotation that stops humidifying unit 20 through about 8 minutes, before the humidification member 32 beginning dryings of humidifying unit 20, part in the water that does not immerse the posterior region 22B that holds water ware 22 on the humidification member 32 of humidifying unit 20 is immersed in the water of the posterior region 22B that holds water ware 22, the humidification member 32 whole wetting degree of dripping that reach.Whereby, under air quantity is weak state, keep humidification member 32 whole wetting states all the time.

Like this, control part 38 is according to the driving condition (in other words, promptly above-mentioned air output) of fan 17, and the official hour interval to determine according to this driving condition is revolved humidifying unit 20 and turned around.Whereby, even under the state that does not carry out the humidification operation, the integral body of humidifying unit 20 is held the water-wet (wetting to the degree of dripping) of water ware 22 all the time, so humidifying unit 20 can not become leather hard.Consequently, can stop to prevent under the state of humidification operation to make us uncomfortable stink with what leather hard produced from humidifying unit 20.And, if control part 38 can make at least one circle of humidifying unit 20 rotations in each time interval, also can make humidifying unit 20 rotation multi-turns.Like this, can reliably humidifying unit 20 integral body be immersed repeatedly in the water of the posterior region 22B that holds water ware 22 and it is wetting.

In addition, detected air quantity is strong more, and control part 38 makes humidifying unit 20 rotations with the relatively short time interval more.Whereby, no matter the intensity of air output how, can remain the state that humidifying unit 20 integral body are held the water-wet in the water ware 22, thereby prevent that reliably humidifying unit 20 from becoming leather hard.

And, operate in air cleaning (is "No" at step S1) under the situation of closing, because air does not flow through air flow channel 15, part in the water that does not immerse rear side field 22B on the humidification member 32 becomes and is difficult to drying and does not produce stink, be not discharged into machine exterior if produce stink in addition yet, so also can not prevent dry control (particularly, the processing of step S6～S9).In addition, operate at humidification (is "Yes" at step S2) under the situation about opening, because humidifying unit 20 is rotated (step S3) all the time, so there is no need to prevent dry control with regard to making humidifying unit 20 rotations every the stipulated time.

In addition, operate to (is "No" in step 2) under the situation of closing at air purifier for opening humidification, by carrying out above-mentioned prevent dry control (processing of step S6～S9), even do not stop the air cleaning operation or painstakingly do not weaken air output, it is can prevent uncomfortable stink yet and be discharged to machine exterior in order to postpone stink to discharge the time of machine exterior a little.Therefore, when continuing the air cleaning operation, can prevent that also making us uncomfortable stink is discharged to machine exterior with desired air output.

In addition, because humidification member 32 is the cloth material, so dehydration property is poor, form leather hard easily, but by the above-mentioned dry control that prevents, humidification member 32 does not become leather hard, so can be suppressed at and produce above-mentioned assorted bacterium on the humidification member 32, whereby, the frequency of maintenance humidification member 32 tails off, so can improve the convenience of use.

And, the driving condition of fan 17 for divide three grades switch air outputs be strong, in, weak state, but under situation about air output not being switched, as long as humidifying unit 20 is rotated with the time interval that is fit to air output.

The assembling of＜humidifying unit 〉

In Fig. 4, Fig. 4 (a) is the three-dimensional exploded view of humidification member 32; Fig. 4 (b) is the stereogram of the humidification member 32 after finishing.Fig. 5 A is the front view of humidifying unit 20, and this figure is used to illustrate the order that humidification member 32 is installed to supporter 34.Fig. 5 B is the sectional view along the B-B direction of arrow of Fig. 5 A.

Below, with reference to Fig. 4, the assembling (being that humidification member 32 is installed to supporter 34 particularly) of humidifying unit 20 is described.

At first, with reference to Fig. 4 (a), as mentioned above, humidification member 32 forms band shape by the cloth material with water imbibition and retractility.The cloth material of humidification member 32 for example can use fibers such as polyester.

Next, on humidification member 32, an end on its length direction (left end of Fig. 4 (a) is called coiling top 32A) and an other end (right-hand member of Fig. 4 (a) is called coiling terminal 32B) all form tubular (loop shape).Here, the size on the length direction of humidification member 32 is littler than the girth of the neighboring of supporter 34 (with reference to Fig. 5 A).

Coiling top 32A and coiling terminal 32B at tubular penetrate elongated pin 40 respectively along the direction (fore-and-aft direction of air purifier 1 is with reference to Fig. 1) with humidification member 32 length direction quadratures.

Pin 40 comprises a portion 41 and axial region 42 at its length direction.Posture with Fig. 4 (a) is a benchmark, and tube portion 41 is configured in the side in front of axial region 42.Below, also the posture with Fig. 4 (a) is a benchmark, respectively tube portion 41 and axial region 42 is described.

Tube portion 41 is for to have the columnar structured of central shaft, and described central shaft extends on the length direction of pin 40, is with the flange part 43 of ring-type in face of tube portion 41 outside the end of side.The end face of side in face of the flange part 43 be provided with integratedly in face of side-prominent fitting portion 44, this fitting portion 44 is the circulus in the center of circle for the center of circle with flange part 43, and diameter is littler than flange part 43.The fitting portion 44 outer ends of side in front that are enclosed within a portion 41.In this state, in face of the tube portion 41 end of side than fitting portion 44 in face of side-prominent.For tube portion 41, the end in the inboard becomes its inner opened state.

Axial region 42 is long on the length direction of pin 40, is with above-mentioned flange part 43 outside the inboard end of axial region 42.On the end face (position that in Fig. 4, can't see) of the inboard of the flange part 43 of axial region 42, be provided with above-mentioned fitting portion 44 integratedly, this fitting portion 44 is outer to be embedded in the inboard end of axial region 42 and side-prominent inwards.Under this state, the inboard end of axial region 42 is given prominence to (with reference to Fig. 5 B) than fitting portion 44 to inboard (rear side).

And flange part 43 and fitting portion 44 are integrally formed with corresponding tube portion 41 or axial region 42.

Axial region 42 inserts the inside of tube portion 41 from the inboard, under this state, slide (also can be described as a portion 41 slides with respect to axial region 42) with respect to tube portion 41 by axial region 42, can change the total length of pin 40.At this, disc spring 45 to be to be embedded on the axial region 42 outside the compressed state between the flange part 43 of the end face of the inboard of tube portion 41 and axial region 42, and whereby, axial region 42 will be from tube portion 41 away from (in other words, promptly sell 40 total length and will become big).In addition, axial region 42 to greatest extent with tube portion 41 away from state under because the claw 46 that is located in the portion 41 blocks axial region 42, come off from tube portion 41 so can prevent axial region 42.

And, under pin 40 inserts state among coiling top 32A and the coiling terminal 32B respectively, shown in Fig. 4 (b), each sells 40 length direction both ends (the particularly flange part separately 43 of tube portion 41 and axial region 42), and a pairing side exposes from coiling top 32A and coiling terminal 32B.Under this state, clip pairing coiling top 32A and coiling terminal 32B because respectively sell the flange part 43 of 40 tube portion 41 and axle 42, come off so can prevent each pin 40 coiling top 32A and coiling terminal 32B from correspondence.

Then, shown in Fig. 5 A, a position in the neighboring of the supporter 34 of humidifying unit 20 on the circumferencial direction of (particularly, i.e. the neighboring separately of header board 30 and back plate 31) is formed with first fastener 47.In addition, the position different with first fastener 47 of (neighboring separately of header board 30 and back plate 31) is (in Fig. 5 A in the neighboring of supporter 34, with respect to first fastener 47 offset some small amount is arranged in the clockwise direction), be provided with a plurality of (is 3 at this) second fastener 48, described second fastener 48 is spaced from each other setting with about equally interval on the Zhou Fangxiang of the neighboring of supporter 34.According to from first fastener 47 order from the close-by examples to those far off, described 3 second fasteners 48 are made as the second fastener 48A, the second fastener 48B, the second fastener 48C respectively.

On supporter 34, from fore-and-aft direction (Fig. 5 A vertical direction) with paper, first fastener 47 of header board 30 sides and first fastener 47 of back plate 31 sides align mutually, and each second fastener 48 of header board 30 sides aligns mutually with the second corresponding fastener 48 of back plate 31 sides.

At this, first fastener 47 and second fastener 48 the two, on the Zhou Fangxiang of the neighboring of supporter 34, all be positioned at the position of staggering each beam parts 33 (with reference to Fig. 6).

With the state shown in Fig. 5 A is benchmark, first fastener 47 and second fastener 48, be that neighboring (neighboring separately of header board 30 and back plate 31) from supporter 34 is towards the center of circle of supporter 34 side (axle 37 sides), along supporter 34 radially with the recessed otch of linearity, this otch is roughly U-shaped.

In addition, on the front of the back of header board 30 and back plate 31, be integrally formed with rib on the part that aligns in deepest part (from the immediate part in the center of circle of supporter 34) respectively and (be called only rib 49 of card with pairing first fastener 47 or each second fastener 48, with reference to Fig. 7 described later), look up from front and back, described rib is deepest part that surrounds pairing fastener and the roughly C shape of opening wide in the neighboring of supporter 34.It is side-prominent backward that the card of the back of header board 30 ends rib 49, and then the card of the front of plate 31 ends rib 49 side-prominent forward (with reference to Fig. 7).

For this kind supporter 34, reeled from the outside radially of supporter 34 amount in about 1 week of humidification member 32.

Particularly, at first, shown in Fig. 5 A, on humidification member 32, coiling top 32A (that is, insert among the coiling top 32A pin 40) is configured in the outside (also please refer to the pin 40A of the top of Fig. 5 B) that the footpath of supporter 34 makes progress with respect to first fastener 47.

Next, with move radially (with reference to the heavy line arrow) of coiling top 32A (inserting the pin 40 among the coiling top 32A) along supporter 34, make it near first fastener 47, and shown in the pin 40B of last several second figure among Fig. 5 B, the pin 40 of coiling top 32A is clamped compression from length direction (fore-and-aft direction) two outsides.At this moment, on pin 40B, the fitting portion 44 of tube portion 41 and the interval of axial region 42, and the card interval of ending between the rib 49 that the card on first fastener 47 of header board 30 ends on first fastener 47 of rib 49 and back plate 31 is roughly the same, it is little perhaps to end rib 49 interval each other than card.

Then, coiling top 32A is continued near first fastener 47, and make in first fastener 47 of front end (left end of Fig. 5 B) income header board 30 of pin 40 of coiling top 32A, and in first fastener 47 with income back, rear end (right-hand member of Fig. 5 B) plate 31 of the pin 40 of coiling top 32A.

Then, if the tube portion 41 on the pin 40 of coiling top 32A and the fitting portion separately 44 of axial region 42, the card that enters on first fastener 47 that card on first fastener 47 of header board 30 ends rib 49 and back plate 31 ends between the rib 49, then shown in the pin 40C that goes up several the 3rd figure among Fig. 5 B, the chucking power of clamping pin 40 is loosened, and is elongated to the original length up to compressed pin 40 before.

So, on the pin 40C of coiling top 32A, the card that one of fitting portion 44 clicks of tube portion 41 embeds first fastener 47 of header board 30 from rear side (right side of Fig. 5 B) ends the inboard of the above-mentioned roughly C shape part (with reference to Fig. 7) of rib 49, and (left side of Fig. 5 B) embeds the inboard that the back card of first fastener 47 of plate 31 ends rib 49 and of fitting portion 44 clicks of tube portion 42 is from the front side.Whereby, finishing coiling top 32A (inserting the pin 40 among the coiling top 32A) ends with respect to the card of first fastener 47.

Under this state, as long as do not compress pin 40 (pin 40C) once more, each fitting portion 44 just can not end rib 49 and come off from the card of correspondence.In addition, the front end of pin 40 (tube portions 41) is limited to the deepest part (with reference to Fig. 5 A) of first fastener 47 of header board 30, and the rear end of pin 40 (axial regions 42) is limited to the deepest part of first fastener 47 of back plate 31.

Like this, after coiling top 32A was limited on first fastener 47, humidification member 32 was wound on the supporter 34 shown in Fig. 5 A between header board 30 and back plate 31 in a clockwise direction.At this moment, humidification member 32 is reeled to surround the above-mentioned mode of a plurality of beam parts 33 (with reference to Fig. 7) of configuration in the form of a ring.Consequently, the humidification member 32 of being reeled on the supporter 34 is the shape that is similar to ring-type (just round).

At this, as mentioned above, because the size on the length direction of humidification member 32 (natural length) is less than the girth of the neighboring of supporter 34, if so under the state that does not stretch, humidification member 32 is wound on the supporter 34, then on humidification member 32, coiling terminal 32B can't reach coiling top 32A.

Therefore, next, coiling terminal 32B is stretched along the clockwise direction among Fig. 5 A, thereby elongate humidification member 32.Whereby, the size on the length direction of humidification member 32 becomes greater than the girth of the neighboring of supporter 34.

Then, with coiling terminal 32B (strictly speaking, promptly inserting the two ends of the length direction of the pin 40 among the coiling terminal 32B), be limited to some (in Fig. 5 A) in a plurality of second fasteners 48 from the second nearest fastener 48A of first fastener 47.Coiling terminal 32B is limited to the order of second fastener 48, identical with the described order that is used for coiling top 32A (inserting the pin 40 of coiling top 32A) is limited to first fastener 47.

Like this, promptly finished the assembling of humidifying unit 20.

Under this state (with reference among Fig. 5 B by under accompanying drawing), coiling top 32A and coiling terminal 32B respectively sell 40 front end and rear end, expose from the front of pairing header board 30 or the back of back plate 31.At this, in the front of header board 30 and the back of back plate 31, the circumferential edge of the part of aliging recessed (this part being called " recessed portion 51 ") with first fastener 47 and second fastener 48, and respectively sell the recessed portion 51 of the back of front that 40 front end and rear end be positioned at header board 30 or back plate 31, and can not expose to the outside than the front of header board 30 or the back of back plate 31.Therefore, when humidifying unit 20 is rotated as mentioned above, block on humidifying unit 20 parts on every side by front end, the rear end of each pin 40, humidification member 32 can be from supporter 34 accidental.

And, under situation about humidification member 32 being pulled down from supporter 34 in order to dismantle humidifying unit 20, with reference to Fig. 5 A, at first, on coiling terminal 32B, by pin 40 being carried out above-mentioned clamping compression, the fitting portion separately 44 of tube portion 41 and axial region 42 is ended rib 49 from the card of correspondence to be taken off, then, coiling terminal 32B is moved to the radial outside of supporter 34, to take off from second fastener 48.Next, if with the identical order of coiling terminal 32B, with coiling top 32A after first fastener 47 takes off, the part beyond coiling top 32A on the humidification member 32 and the coiling terminal 32B is taken off from supporter 34, then humidification member 32 integral body are removed from supporter 34.

Then, after the assembling of finishing humidifying unit 20, under the state of humidification member 32 being bestowed suitable tension force it is being wound on the supporter 34 (particularly, being a plurality of beam parts 33).Then, be limited to the coiling top 32A of first fastener 47 and be limited to the coiling terminal 32B of second fastener 48, overlapping on the Zhou Fangxiang of the neighboring of supporter 34.Therefore, very close to each other between coiling top 32A and the coiling terminal 32B on the Zhou Fangxiang of the neighboring of supporter 34.Whereby, the air that can prevent air flow channel 15 (with reference to Fig. 1) by the gap between coiling top 32A and the coiling terminal 32B described air under not by the state of humidification member 32 humidifications, discharge from exporting 7, and then can suppress the reduction of humidification efficiency.

Then, as mentioned above, humidification member 32 is wound on the supporter 34 along the neighboring of supporter 34.That is to say and since by with humidification member 32 from outside be wound on and finish humidifying unit 20 on the supporter 34, so when humidification member 32 is maintained, can not carry out dismounting to humidification member 32 even do not dismantle supporter 34 yet.Whereby, the maintenance mode of humidifying unit 20 can improve the convenience of use.In addition, have the humidifying unit 20 of said structure, compare, can cut down its number of components (being cost) with humidifying unit with structure that on supporter 34 many humidification dishes of assembled layers poststack replace humidification member 32 etc.

At this, shown in Fig. 5 A, the coiling terminal 32B that is set as humidification member 32 is limited to the state of second fastener 48, in this case, along with the use of humidification member 32, also might it extend in the longitudinal direction.

In this case, as long as the coiling terminal 32B of humidification member 32 is taken off from the second fastener 48A (near second fastener 48 of first fastener 47), again engage to the second fastener 48B and 48C (from first fastener 47 away from second fastener 48) on, just humidification member 32 can not had and loosely be wound on the supporter 34.Whereby, even under the situation that humidification member 32 takes place to elongate, can not have lax state with the humidification member that is elongated yet and assemble humidifying unit 20.

In addition, because be wound on the humidification member 32 on the supporter 34 not laxly, be clipped between header board 30 and the back plate 31 or when humidifying unit 20 rotations, be stuck in situation on the parts around the humidifying unit 20 so can prevent humidification member 32.In addition, the same with the new humidification member 32 before being elongated, because be under the state of the humidification member 32 after being elongated being bestowed suitable tension force and it is wound on the supporter 34, so same stable humidifying performance and being kept can make humidification member 32 have the time with new product.By the way, if humidification member 32 is lax, between part lax on the humidification member 32 and supporter 34, can produce the gap, thus the air that flows through air flow channel 15 from this gap by and not by humidification member 32 humidifications, and then the sorrow of the humidification efficiency of causing reduction is arranged.

Like this, coiling humidification member 32 and coiling top 32A and coiling terminal 32B are limited to supporter 34 respectively just can finish humidifying unit 20 on supporter 34 only, such structure is all easy to the assembling and the dismounting of humidifying unit 20.

At this, be provided with 3 second fasteners 48, but the quantity that can come appropriate change second fastener 48 according to the elongation situation of humidification member 32.In addition, under the situation that humidification member 32 shortens or under the state of humidification member 32 being bestowed excessive tension force, humidification member 32 is wound under the situation of supporter 34, as long as the coiling terminal 32B card of humidification member 32 is ended near on second fastener 48 of first fastener, 47 sides, then can bestow above-mentioned suitable tension force to the humidification member 32 that is wound on the supporter 34.

Fig. 6 is the stereogram according to the humidifying unit 20 of first variation.

At this, in the above-described embodiment, 3 second fastener 48 independent settings on header board 30 and back plate 31 respectively, but the setting that also can link to each other as shown in Figure 6.

Particularly, on the same position of Zhou Fangxiang of header board 30 and back plate 31, be formed with respectively and see the otch 50 that is roughly L shaped from the front.This otch 50, extending the back from the neighboring of plate body towards center of circle straight line on pairing header board 30 or back plate 31 bends, towards see from the front clockwise direction (from first fastener 47 away from direction) extend along the Zhou Fangxiang of plate body, on fore-and-aft direction, run through pairing plate body.

The part that bending takes place in such otch 50 is provided with the second fastener 48A; This second fastener 48A is provided with the second fastener 48B to the position that the direction away from first fastener 47 departs from relatively, and the relative second fastener 48B is provided with the second fastener 78C to the position that the direction away from first fastener 47 departs from.

In this case, when the coiling terminal 32B card with humidification member 32 ends at second fastener 48, on coiling terminal 32B, make pin 40 shown in pin 40A like that near the second fastener 48A and shown in pin 40B, compress like that after the pin 40, with reference to pin 40C, be embedded in each otch 50 of header board 30 and back plate 31, and make pin 40 be limited to the second fastener 48A.Wherein, in Fig. 6, for convenience of explanation, will sell the 40 and second separately expression of fastener 48.

At this, as mentioned above, if humidification member 32 (with reference to Fig. 4 (b)) elongation, compression pin 40 shown in pin 40D, and coiling terminal 32B is taken off from the second fastener 48A, and in each otch 50, move to the second fastener 48B and the second fastener 48C lateral deviation.Then, among the second fastener 48B and the second fastener 48C, will sell the position of 40 elongations (with reference to pin 40E), thereby coiling terminal 32B will be limited to the corresponding second fastener 48B and the second fastener 48C to expectation card second fastener 48 only.And, ending rib 49 with the corresponding respectively card of second fastener 48A～C is not above-mentioned roughly C font, but under coiling terminal 32B was limited to any one state among second fastener 48A～C, described card ended rib 49 and keeps each fitting portion 44 of the pin 40 of coiling terminal 32B that it can not be come off.

Fig. 7 is the stereogram according to the humidifying unit 20 of second variation.

Do not have at humidification member 32 under the situation of above-mentioned retractility,, so as shown in Figure 7, on header board 30 and back plate 31, one second fastener 48 is set respectively and gets final product because there is no need to elongate humidification member 32 to change its length.

＜electrolysis water unit 〉

For this air purifier 1, as shown in Figure 1, on humidifying unit 20, electrolysis water unit 70 is located in the inner space 35 of supporter 34.Particularly, electrolysis water unit 70 is configured in the space of inner space 35 internal ratio axles 37 by upside.Whereby, electrolysis water unit 70 and humidifying unit 20 are positioned at fore-and-aft direction (Fig. 1 is a left and right directions) and go up identical position, electrolysis water unit 70 be positioned at humidifying unit 20 the upper end under.The spaced walls 9 of body housing 2 supports described electrolysis water unit 70.

Electrolysis water unit 70 carries brine electrolysis on the flow air in air flow channel 15 after purifying by filter 16.Therefore, this air purifier 1 is not only as described above the extraneous air that will introduce and is purified and humidifications at filter 16, but also can make the brine electrolysis diffusion by electrolysis water unit 70, and with this brine electrolysis the air of outside (indoor) is carried out sterilization or deodorization.

Particularly, electrolysis water unit 70 possesses water container 71, rising plate 72, gear 73 and the electrode unit 90 (with reference to aftermentioned Fig. 8) that upper surface opens wide.

Rising plate 72 is the circular plate shape that are formed with many through holes 74 (also with reference to aftermentioned Figure 10).These through holes 74 are that benchmark is radial arrangement with the center of circle of rising plate 72, and the length direction of through hole 74 is along the circumferencial direction of rising plate 72.The state that rising plate 72 tilts with towards below, oblique front side (serving as below, oblique left side among Fig. 1) is maintained in the water container 71.

Gear 73 is for having the disc-shaped structure of central shaft, and described central shaft extends upward at upper and lower, is formed with the gear teeth 75 at the outer peripheral portion of gear 73.In addition, the home position in the bottom surface of gear 73 is connected with the upper end of gear shaft 76, and this gear shaft 76 extends upward at upper and lower.The bottom of gear shaft 76 is connected to the center of circle part of the rising plate 72 that is in above-mentioned heeling condition from the top, whereby, and rising plate 72 and gear 73 becoming one.Under this state, rising plate 72 and gear 73 together rotate freely with gear shaft 76.And rising plate 72 is kept the state that tilts all the time below oblique front side in rotation.

Electrode unit 90 is contained in (with reference to Fig. 8) in the water container 71, comprises the pair of electrodes (not shown) that is connected with the body power supply (not shown) of the outside of electrolysis water unit 70.On electrolysis water unit 70, accumulate in water in the water container 71 under the effect of electrode unit 90 (with reference to Fig. 8) by electrolysis, and produce brine electrolysis.

At this, be formed with the gear teeth 77 (with reference to Fig. 7) in the inner periphery of the supporter 34 (particularly, promptly header board 30) of humidifying unit 20 along whole circumference, the gear teeth 77 of the gear teeth 75 of electrolysis water unit 70 1 sides and humidifying unit 20 1 sides are meshed.And the part on the electrolysis water unit 70 beyond the gear teeth 75 does not touch humidifying unit 20.

As mentioned above, if humidifying unit 20 is rotated as mentioned above like that, then the outer peripheral portion of humidifying unit 20 (just being wound on humidification member 32 on the supporter 34 in humidifying unit 20) is around electrolysis water unit 7 rotations.At this moment, when rise because of the rotation that adds wet end 32 in the bottom of humidification member 32, this bottom is immersed and is held the water that water ware 22 absorbed and can be exposed in the air that flows through air flow channel 15, and as mentioned above to this air wetting.

At this, exist to be helpless to air wetting and from the unrestrained water of humidification member 32.In addition, support accompanying water on the supporter 34 of humidification member 32 sometimes, the surface along with the rotation of humidification member 20 along supporter 34 is unrestrained.When these water levels were directly over electrolysis water unit 70, these water fell and accumulate in the water container 71 from humidifying unit 20.Based on the water that is accumulated in the water container 71, generate brine electrolysis at electrolysis water unit 70.

Below, to the generation detailed description of brine electrolysis.The water level of the water that is accumulated in water container 71 rises when reaching predetermined water level (with reference to water surface T), and the pair of electrodes (not shown) of above-mentioned electrode unit 90 (with reference to Fig. 8) is immersed in the water that accumulates in water container 71.

And by imposing on from the voltage of above-mentioned body power supply (not shown) on the pair of electrodes (not shown) of electrode unit 90, the water in the water container 71 can be become brine electrolysis by electrolysis.Generally can use running water for water because contain chlorine in the running water, so electrolysis water unit 70 by electrolysis, can generate at electrode unit 90 contain possess sterilization, the brine electrolysis of the hypochlorous acid of deodorization functions (HClO), active oxygen.

At this, when the water that accumulates when water container 71 reaches the afore mentioned rules water level, rising plate 72 tilts to below, oblique front side with respect to the water surface T of water container 71, and the front part of rising plate 72 (roughly first half) is immersed in the water (brine electrolysis) that water container 71 accumulated.And as mentioned above, in electrolysis water unit 70, the gear teeth 75 of

gear

73 and 77 engagements of the gear teeth of humidifying unit 20 are so when humidifying unit 20 rotations, gear 73 can be subjected to the revolving force of humidifying unit 20 and rotate.

Then, rotation along with gear 73, form the rising plate 72 of one with gear 73 by gear shaft 76, kept above-mentioned to tilt and its front part when being immersed in state in the water of water container 71 by gear shaft 76, synchronously rotated with the rotation of humidifying unit 20 to below, oblique front side.

The front part of the rising plate 72 in being immersed in the water (brine electrolysis) that accumulates in the water container 71, form the film of brine electrolysis because of surface tension at the above-mentioned through hole 74 of rising plate 72, rotate under this state by described rising plate 72, the through hole 74 of opening the film that is provided with brine electrolysis moves to the rear side of rising plate 72, and the brine electrolysis of water container 71 is taken out continuously.So, the through hole 74 of opening the film that is provided with brine electrolysis is exposed to (with reference to the heavy line among Fig. 1) in the air that flows through air flow channel 15 successively at the rear section of rising plate 72.The air that the film of brine electrolysis is flow through air flow channel 15 is broken to vaporific and peels off from through hole 74, thereby brine electrolysis is rising continuously.

Then, this vaporific brine electrolysis (electrolysis water smoke) is subsidiary to be flow through the air of air flow channel 15 and rises, successively by between header board 30 on the humidifying unit 20 and the back plate 31 and humidification member 32, and with cleaned air passes from export 7 be discharged to indoor.

Like this, rising plate 72 carries the brine electrolysis that is generated in the air that flows through air flow channel 15.Whereby, brine electrolysis becomes vaporific, is diffused in machine exterior (for example indoor) inlet chamber from exporting 7, thereby room air is carried out sterilization, deodorization.

At this, humidification member 32 can be made by polyamide.Polyamide and brine electrolysis compatibility are good, and the concentration of the brine electrolysis by humidification member 32 (specifically referring to the concentration of above-mentioned hypochlorous acid, active oxygen) is not easy decline.Therefore, by will be when generating mutually the brine electrolysis that becomes hardly of specific concentration spread to machine exterior, can be to the effective sterilization of indoor air, deodorization.

And this electrolysis water smoke prevents the effect of assorted bacterium breeding in addition for humidification member 32, keeps humidification member 32 thereby can clean.

At this, be positioned on the humidifying unit 20 electrolysis water unit 70 directly over water droplet W from humidifying unit 20 under the situation that water container 71 falls, perhaps the water that overflows from water container 71 becomes water droplet W and to holding under the situation that water ware 22 falls, and the water droplet W that falls is to the water container 71 of correspondence or hold the water surface S of water ware 22 or T directly falls and may produce bigger sound.

Therefore, for this air purifier 1, the following describes countermeasure for the sound that prevents to drip.

Fig. 8 is the sectional view along the A-A direction of arrow of Fig. 1.Fig. 9 is the sectional view along the C-C direction of arrow of Fig. 8.

As shown in Figure 9, on water container 71, be provided with integratedly from its antetheca 78 inclined wall 79 of tilt extending of upside backward.At the bottom of inclined wall 79 and antetheca 78 adjoining positions of water container 71, be formed with the slit X that connects inclined wall 79 at above-below direction.Inclined wall 79 is between the water surface T of the upper end of humidifying unit 20 and water container 71.In addition, inclined wall 79 is with respect to the rear section of rising plate 72, on fore-and-aft direction (left and right directions among Fig. 9) forward lateral deviation from, so can the air (with reference to the heavy line among Fig. 9) that flow through air flow channel 15 not counteracted at the rear section of above-mentioned rising plate 72.

If by inclined wall 79 is set like this, even then water droplet W falls from the upper end of humidifying unit 20, because inclined wall 79 is arranged in its front, so water droplet W can directly not drop on the water surface T of water container 71, catch downside before the upper surface of inclined wall 79 flows at once but after falling, be tilted wall 79.Then, the slit X of this water droplet W by the bottom of inclined wall 79 do not flow in the water container 71 along 71 antetheca 78 of water container with sounding, and accumulates in the water container 71.Whereby, because can directly not drop to the water surface T of water container 71, so can prevent to send sound under the water droplet towards the water droplet that water container 71 falls from the water droplet W of the upper end of humidifying unit 20.

And, as shown in Figure 8, division wall 80 will accumulate the part of water and divide (also with reference to Fig. 9) from rear side in water container 71, at the upper end-face edge of dividing wall 80, from back apparent direction (back side), be formed with the upper end-face edge that to divide wall 80 and be cut into the roughly otch 81 of V font downwards from take back the slightly position of side of central authorities at width.And, in the back of dividing wall 80, with respect to otch 81 when the back apparent direction is seen from the left side position adjacent, be provided with the first side-prominent backward guiding rib 82 integratedly.This first guiding rib 82 extends at above-below direction, to link the upper end-face edge and the lower edge of dividing wall 80 for thin tabular of width.In addition, the back edge of second guiding rib 82 downside inclination extension (with reference to Fig. 9) forward.

In addition, in the lower end of dividing wall 80, with the lower end adjoining position of second guiding rib 82, be integrally formed with second guiding rib 83 that extends downwards.Second guiding rib 83 is roughly rectangular when backsight, and the end edge 83A in left side tilts to extend to the lower right side.At this, the front end of above-mentioned axle 37 is embedded with the flange 84 of ring-type outward, and this flange 84 is from the lower end of downside and second guiding rib 83 continuous (with reference to Fig. 9) mutually.

Then, be provided with up and down the 3rd guiding rib 85 that extends integratedly in above-mentioned spaced walls 9, with about cut apart intercommunicating pore 10.The 3rd guiding rib 85 is thin tabular of width, and edge, its rear end 85A is with from the downside extension of tilting forward of below and flange 84 consecutive states, and link to each other with spaced walls 9 (with reference to Fig. 9).In addition, the above-below direction of the 3rd guiding rib 85 midway (particularly being position) near the upper end of the 3rd guiding rib 85 the 4th guiding rib 86 is set integratedly.The 4th guiding rib 86 tilts to extend to the upper left side from the 3rd guiding rib 85 when backsight.

The water that overflows from water container 71 becomes water droplet W, flows downwards along the back of dividing wall 80 from the otch 81 of dividing wall 80.At this moment, from the back apparent direction, water droplet W is caught by first guiding rib 82 in left side, is led away by first guiding rib 82, therefore, can not move excessively to the left, but flow downwards along the back edge 82A of first guiding rib 82 (with reference to Fig. 9).

Then, the water droplet W that arrives the lower end of first guiding rib 82 is caught by second guiding rib 83, and the end edge 83A in the left side of second guiding rib 83 flows to the lower right side when backsight, then by flange 84 transfers.

The water droplet W that is relayed to flange 84 flows downwards along flange 84, then by 85 transfers of the 3rd guiding rib.At this moment, there is the situation that directly is relayed to the 3rd guiding rib 85 from the water droplet W of flange 84, also has the situation that becomes big and then be relayed to the 3rd guiding rib 85 with other water droplet interflow at once by 86 transfers of the 4th guiding rib.

Then, be relayed to the water droplet W of the 3rd guiding rib 85, as shown in Figure 9 after the back edge 85A of the 3rd guiding rib 85 descends side flow forward, be spaced apart in the wall 9 then along the back of spaced walls 9 and the back of holding the demarcation strip 25 of water ware 22 flow downwards successively, at last, inflow is held the posterior region 22B of water ware 22 and is accumulated down under the state of not sounding.

Whereby, can directly not fall the water surface S that holds water ware 22, so can prevent to overflow towards holding water droplet W that water ware 22 the falls sound that drips from water container 71 from the water droplet W of water container 71.

Below, will be elaborated to rising plate 72.

Figure 10 is at according to the rising plate 72 (Figure 10 (a)) of first comparative example, show the vertical view of rising plate 72 and about the chart of the rising performance of rising plate 72 according to the rising plate 72 (Figure 10 (b)) of second comparative example and according to the rising plate 72 (Figure 10 (c)) of present embodiment.And, among Figure 10 (b) and Figure 10 (c), on right end position, also show the sectional view of the major part of rising plate 72.

Size about rising plate 72, for the rising plate 72 of first comparative example of Figure 10 (a), its external diameter is 71mm, and size (lengthwise dimension) Y of each through hole 74 on length direction (tangential direction of the circumferencial direction of rising plate 72 strictly speaking) is 23mm.And, the surface smoothing (surface does not have concavo-convex) of the rising plate 72 of first comparative example.

In addition, the rising plate 72 of second comparative example shown in Figure 10 (b), external diameter are 67mm, and the size Y of the length direction of each through hole 74 is 21.5mm.Therefore, compare with the rising plate 72 of first comparative example, the rising plate 72 of second comparative example, external diameter still are that the lengthwise dimension Y of each through hole 74 is smaller.Particularly, the lengthwise dimension Y of the through hole 74 of second comparative example is littler by about 1/10th than first comparative example.In addition, the surface of the rising plate 72 of second comparative example, the same level and smooth with the rising plate 72 of first comparative example.And the quantity of through hole 74 is identical with the rising plate 72 of first comparative example.

At this, film at each through hole 74 formed brine electrolysis of rising plate 72, whenever revolve every unit interval or rising plate 72 and to turn around, be broken to and vaporificly peel off and the airborne amount (rising amount) of carrying air flow channel 15 (with reference to Fig. 1) is called transpiration rate from through hole 74.The unit of transpiration rate herein is (cc/ hour).For the rising plate 72 of first comparative example, if air output is above-mentioned " by force ", then transpiration rate is 13, if air output be above-mentioned " in ", then transpiration rate is 6, if air output is above-mentioned " weak ", then transpiration rate is 4 (with reference to the tables of Figure 10 (a)).

Relative therewith, rising plate 72 for second comparative example, if air output is " by force ", transpiration rate is 8, if air output be " in ", transpiration rate is 3, if air output is " weak ", then transpiration rate is 1, no matter is which air output promptly, and transpiration rate all reduces (with reference to the table of Figure 10 (b)) than first comparative example.This be because, rising plate 72 for second comparative example, compare with the rising plate 72 of first comparative example, because its through hole 74 diminishes, so become is not easy brokenly the film of each through hole 74 formed brine electrolysis (with reference to the film M on the sectional view of the right-hand member of Figure 10 (b)), thereby transpiration also becomes and is not easy.Conversely, if the size of through hole 74 is made the size identical with first comparative example, because the quantity of through hole 74 reduces, the result compares transpiration rate with first comparative example and tails off.

Therefore, can make the size of rising plate 72 identical with second comparative example, shown in Figure 10 (c), and (being the part 72A that each through hole 74 is constituted frames at least, with reference to the sectional view of the right-hand member of Figure 10 (c)) gone up by bestowing pitted skin processing and formed trickle concavo-convex (with reference to the part that is coated with a little) on the surface of rising plate 72.At this, about described concavo-convex, forming concavo-convex height at the die surface that forms rising plate 72 is concavo-convex about 0.4mm, and when forming concavo-convex height on the surface of rising plate 72 and being mould about 60% concavo-convex.Form the concavo-convex of die surface by immersing special medicament at mould.

Whereby, in the present embodiment that Figure 10 (c) illustrates,, also break easily than the rising plate 72 of first comparative example at the film of each through hole 74 formed brine electrolysis even the rising plate 72 of through hole 74 to the first comparative examples is little.Therefore, under the situation of carrying out pitted skin processing as present embodiment, even the size of rising plate 72 and second comparative example are equally little, if air output is " by force ", transpiration rate also is 14; If air output be " in ", transpiration rate also is 7; If air output is " weak ", transpiration rate is 5.Which kind of air output no matter, transpiration rate is all many than first comparative example.

Like this,, can suppress the reduction of transpiration rate and pursue the miniaturization of rising plate 72, so, can pursue the miniaturization of air purifier 1 integral body effectively along with the miniaturization of rising plate by carry out pitted skin processing on the surface of rising plate 72.

The present invention is not limited to above-mentioned embodiment, also can carry out various changes within the scope of the invention.
