As a result, one of the air RA from the bathroom 100 that cyclical breathing suction inlet 20A is sucked due to impeller 25A rotation Divide and is flowed to the first blow-off outlet 21A and the second blow-off outlet 22A.Moreover, from the bathroom 100 that cyclical breathing suction inlet 20A is sucked The remainder of air to ventilation blow-off outlet 23A flowing, by exhaust passage 102 as exhaust EA outside room grid 102a to It is vented outside room.

Under dry operating mode, the air for flowing to the first blow-off outlet 21A is heated by heater 5, thus from foreboard 4A's First blow-off outlet grid 41A blows out hot wind HA.The air for flowing to the second blow-off outlet 22A does not pass through heater 5, therefore from foreboard 4A The second blow-off outlet grid 42A blow out air A corresponding with room temperature.

It is dried in heat supplier 1A in bathroom aerating, length of the air blown out from the first blow-off outlet grid 41A in clothes airing-tube 105 Degree direction and the side orthogonal with clothes airing-tube 105 extend up.

But the length direction of the first blow-off outlet grid 41A is configured to and clothes airing-tube by the dry heat supplier 1A of bathroom aerating 105 orthogonal directions, therefore the air blown out from the first blow-off outlet grid 41A is mainly on the direction orthogonal with clothes airing-tube 105 Extension.

Therefore, hot wind width direction on the whole be hung on the first blow-off outlet grid 41A it is immediately below near dry in the air The contact of the dried object such as the clothing on clothing pipe 105.In contrast, being difficult to directly from the hot wind that the first blow-off outlet grid 41A is blown out It is contacted with being hung on from the dried object on the clothes airing-tube 105 of the isolated position immediately below of the first blow-off outlet grid 41A.

In the dry heat supplier 1A of bathroom aerating, the air A blown out from the second blow-off outlet grid 42A utilizes cowling panel 43A, Relative to the first blow-off outlet grid 41A towards setting the second blow-off outlet grid 42A side bathroom 100 wall surface 106a.

As a result, as shown in Fig. 8 (a), from the second blow-off outlet grid 42A air A blown out and bathroom 100 under drying mode The wall surface 106a of a side touch, flowed downwards along wall surface 106a as indicated by arrow a 1.It is flowed downwards along wall surface 106a Dynamic air as indicated by arrow a 2, near the lower layer in bathroom 100, is flowed mainly towards the wall surface 106b of another party.

In the dry heat supplier 1A of bathroom aerating, using the air RA sucked from suction inlet grid 40A in bathroom 100 Generating makes the flowing of air circulation, therefore the air flowed near the lower layer in bathroom 100 towards the wall surface 106b of another party is such as It flows shown in arrow A3 along wall surface 106b, is sucked from suction inlet grid 40A upwards.

In this way, in the dry heat supplier 1A of bathroom aerating, it, can using the air blown out from the second blow-off outlet grid 42A Generate along bathroom 100 a side wall surface 106a downward, towards the wall surface of another party near the lower layer in bathroom 100 106b, along the flowing of the wall surface 106b air upward of another party.

The air blown out under dry operating mode from the first blow-off outlet grid 41A of the dry heat supplier 1A of bathroom aerating by In the hot wind heated by heater 5, relative humidity declines, therefore the air than blowing out from the second blow-off outlet grid 42A is light.

Therefore, than the air of the air weight blown out from the first blow-off outlet grid 41A blown out from the second blow-off outlet grid 42A The lower layer for flowing to bathroom 100, the entirety in bathroom 100 can generate the flowing for the wind being stirred to air.

Even if being blown as a result, in the hot wind blown out from the first blow-off outlet grid 41A being hung on from first of being difficult to directly touch It exports near the dried object on the clothes airing-tube 105 of the isolated position immediately below of grid 41A, can also generate the stream of air It is dynamic.

In the structure for being located in branch portion 52A and having the second blow-off outlet 22A of wind path switching windscreen, from the first blowout The air of mouth 21A blowout is dynamic along the surface current of the inside of wind path switching windscreen, and the air blown out from the second blow-off outlet 22A is along wind The surface current that road switches the outside of windscreen is dynamic.In such a configuration, an adequate amount of air is blown out from the first blow-off outlet 21A.It is another Aspect, since the flowing to the air blown out from the second blow-off outlet 22A rectifies, in the outside of wind path switching windscreen Rectification element is needed to have on face.

However, can not also blow out the air of full amount from the second blow-off outlet 22A even if having rectification element.Moreover, working as When wind path switching windscreen is in cyclical breathing position, exhaust wind path constriction is unable to ensure ventilation air quantity.

It is opened moreover, switching windscreen by the wind path of independent part in the first blow-off outlet 21A and the second blow-off outlet 22A In the structure closed, can ensure that air quantity position configure windscreen, but will lead to parts count increase it is associated at This rising, the decline of assemblability, also becoming that work is undesirable will be because.

In contrast, wind path switch windscreen 6A than branch portion 52A by air flow direction upstream side position from Branch portion 52A vacates defined distance and is equipped with axis 60A.As a result, in the wind path switching windscreen 6A in cyclical breathing position, The air blown out by the first blow-off outlet 21A from the first blow-off outlet grid 41A switches the face of the inside of windscreen 6A along wind path Flowing.

Moreover, extending in the wind path switching windscreen 6A in cyclical breathing position from axis 60A to the side branch portion 52A The end of secondary wind path switching part 62A is in from the position that branch portion 52A is separated, therefore the second blow-off outlet 22A is opened.Lead to as a result, Cross the second blow-off outlet 22A and the face from the air of the second blow-off outlet grid 42A blowout also along the inside of wind path switching windscreen 6A Flowing.

Therefore, required an adequate amount of air is stirred to the air in bathroom 100 to blow from the second blow-off outlet grid 42A Out, in the flowing using the air in the bathroom 100 of air stirring blown out from the second blow-off outlet grid 42A, can make from An adequate amount of hot wind HA of first blow-off outlet grid 41A blowout is recycled in bathroom 100.

The moisture of dried object is easy evaporation as a result, if the output of heater 5 is as in the past, can shorten drying Time can reduce the required energy of the drying of dried object.Moreover, can make to heat if drying time is as in the past The output of device 5 declines, and still is able to the required energy of the drying of reduction dried object.Moreover, one of the air in bathroom 100 Divide and be vented and take a breath to outside room, therefore can moisture etc. be discharged and be promoted the drying of dried object.

In addition, in the wind path switching windscreen 6A in cyclical breathing position, if on face on the outside there is no constriction to Ventilation blow-off outlet 23A connection ventilation wind path and hinder component as the flowing of air, then do not utilize cyclical breathing fan 2A The revolving speed of cyclical breathing fan motor 26A is set to increase and can ensure defined air quantity of taking a breath.

The increase of sound caused by thereby, it is possible to prevent the revolving speed for making cyclical breathing fan motor 26A from increasing and consumption electricity The increase of power.

In this example, illustrate that clothes airing-tube 105 is 1 example, but even if in the bathroom that 2 clothes airing-tubes 105 are arranged In, the periphery of the dried object hung on the arbitrary position of each clothes airing-tube can also generate the flowing of air, therefore can Reduce the required energy of the drying of dried object.

In addition, under dry operating mode, illustrates to start along with the driving of cyclical breathing fan 2A and drive heating Device 5 and from operating initially blowout hot wind example, but can also operating initially keep heater 5 non-driven and blowout and room The corresponding air-supply of temperature blows out hot wind after the defined time, driving heater 5.Even if the driving in heater 5 postpones Operating in, the moisture of dried object also be easy evaporation, can reduce the required energy of the drying of dried object.

The dry heat supplier 1A of bathroom aerating is formed as Fig. 6 institute under cyclical breathing operation mode, by wind path switching windscreen 6A The cyclical breathing position shown, keeps heater 5 non-driven, is driven to cyclical breathing fan motor 26A and revolves impeller 25A Turn.Here, under above-mentioned dry operating mode and cyclical breathing operation mode, in order to make cyclical breathing operation mode to room The i.e. ventilation air quantity of the air quantity of outer exhaust increases, and the aperture that wind path switches windscreen 6A can also be changed to ventilation blow-off outlet 23A's The position that aperture broadens.

It, will from the suction inlet grid 40A of foreboard 4A by the rotation of impeller 25A in the dry heat supplier 1A of bathroom aerating Air in bathroom 100 is drawn into cyclical breathing suction inlet 20A.

Under cyclical breathing operation mode, wind path switching windscreen 6A is in cyclical breathing position, therefore from circulating picture-changing aspiration A part of the air in the bathroom 100 of entrance 20A sucking is flowed to the first blow-off outlet 21A and the second blow-off outlet 22A.Moreover, from The remainder of the air in the bathroom 100 of cyclical breathing suction inlet 20A sucking is vented to ventilation blow-off outlet 23A flowing to outside room.

Under cyclical breathing operation mode, flow to the air of the first blow-off outlet 21A due to heater 5 be it is non-driven, Air CA corresponding with room temperature is blown out from the first blow-off outlet grid 41A of foreboard 4A.The air for flowing to the second blow-off outlet 22A does not lead to Heater 5 is crossed, therefore blows out air A corresponding with room temperature from the second blow-off outlet grid 42A of foreboard 4A.

In the dry heat supplier 1A of bathroom aerating, as shown in Fig. 8 (b), even if under cyclical breathing operation mode, using from Second blow-off outlet grid 42A blowout air, can also generate along a side in bathroom 100 wall surface 106a downward, The lower layer in bathroom 100 is nearby towards the wall surface 106b of another party, along the stream of the wall surface 106b air upward of another party It is dynamic.

Even if the entirety in bathroom 100, which can also generate, stirs air as a result, under cyclical breathing operation mode The flowing for the wind mixed, in bathroom 100, even if being difficult to the position directly touched from the air that the first blow-off outlet grid 41A is blown out, Also the flowing of air can be generated.

Therefore, the drying time of each wall surface, the bottom surface in bathroom 100 etc. can be shortened.Moreover, air in bathroom 100 A part is vented to outside room and is taken a breath, therefore moisture etc. is discharged, and can promote each wall surface, the bottom surface in bathroom 100 etc. It is dry.

It, will under warming operation mode as the other operation modes executed using the dry heat supplier 1A of bathroom aerating Wind path switching windscreen 6A is formed as circulation position shown in fig. 5, is powered to heater 5, and drive cyclical breathing fan motor 26A And rotate impeller 25A.
