  1 A of bathroom ventilation drying heaters are provided with the ion generator 10 as a function factor generation part. The ion generator 10 produces | generates and discharge | releases ion as a functional factor, and removes a microbe. For this reason, the ions mainly function as an air cleaning factor that cleans the air, and the ion generator 10 functions as an air cleaning factor generator that generates and discharges ions.

The ion generator 10 generates both positive ions and negative ions, or at least one of positive ions and negative ions. The principle of generation of positive ions and negative ions is that corona discharge causes oxygen or moisture in the air to be ionized by ionization, and H ⁺ (H ₂ O) _m (m is an arbitrary natural number) and O ₂ ⁻ (H ₂ O) _n (n is an arbitrary natural number) emits ions mainly.

These H ⁺ (H ₂ O) _m and O ₂ ⁻ (H ₂ O) _n adhere to the surface of the fungus and chemically react to generate H ₂ O ₂ or .OH as an active species. Since H ₂ O ₂ or .OH shows very strong activity, they can surround and remove bacteria. Here, .OH is one kind of active species, and represents radical OH.

  Thereby, in the bathroom ventilation / drying / heating machine 1A, the circulation ventilation fan 2A is linked with the operation of the circulation ventilation fan 2A to generate approximately the same number of positive ions and negative ions, and air is circulated by blowing air containing approximately the same number of positive ions and negative ions.

Further, the bacteria attached to the bathroom 100 can be removed to suppress the occurrence of mold and the like. Furthermore, germs adhering to clothing can be removed, and the generation of odor can be suppressed.

  Note that ions may be generated by the ion generator 10 using only positive ions or only negative ions, and other methods may be used instead of corona discharge. Furthermore, as an air purification factor for removing both the floating bacteria contained in the circulating air and the floating bacteria in the bathroom air, other air purification factors such as ozone may be used instead of ions. In addition, the air purifying factor generation unit may use spraying means for spraying silver ions, chemicals for deodorization and sterilization, chemicals that promote the moisturizing effect, etc., and adhere to airborne bacteria or clothing in the air. Any form of air treatment means that imparts a specific function to the air, such as those that suppress the growth of bacteria, those that remove bacteria, and those that release a functional factor having a moisturizing effect May be.

  The ion generator 10 includes an electrode needle that performs corona discharge and a cover (not shown) that covers the electrode needle, and the ion emission unit 10A is configured. The ion generator 10 is installed at a position where it can be easily detached from the main body 3A.

The fixing part 202A detachably fixes the ion generator 10 to the circulation ventilation fan case 27A or the front panel 4A by a combination of concave and convex shapes and a fastening member such as a screw.

  The front panel 4A includes a cover portion 401A that opens and closes a position facing the attachment portion 201A. The cover portion 401A is an example of an opening / closing member that constitutes the attaching / detaching means. In this example, the cover portion 401A opens and closes a part of the front panel 4A by a rotating operation with the shaft 402A as a fulcrum.

  By making cover 401A open, ion generator 10 can be attached to and detached from attachment 201A. Further, the ion generator 10 is attached to the attachment portion 201A, and the cover portion 401A is closed, whereby the ion generator 10 is fixed to the attachment portion 201A.

  In this example, the ion generator 10 may be fixed to the main body 3A side or may be fixed to the front panel 4A side. The cover 401A is provided on the front panel 4A. However, the cover 401A may be provided on the circulation ventilation fan case 27A.

  1 A of bathroom ventilation drying heaters equip the attachment part 201A with the interruption | blocking switch 203A. The shut-off switch 203A is an example of a shut-off means, and is actuated by opening / closing operation of the cover portion 401A. When the cover 401A is in the closed state, when the bathroom ventilation dryer 1A is connected to the power source, the state where the power is supplied is maintained. On the other hand, when the cover 401A is in an open state, the cutoff switch 203A cuts off the supply of power when the bathroom ventilation dryer 1A is connected to the power source.

  The cutoff switch 203A detects the presence or absence of the cover part 401A with a magnetic sensor, for example. Alternatively, the presence or absence of the cover portion 401A is detected by an optical sensor. Alternatively, the presence or absence of the cover portion 401A is detected by a mechanical switch such as a micro switch.

<Operation Example of Bathroom Ventilation Dryer / Heater of First Embodiment>
6-8 is explanatory drawing which shows operation | movement of the air-path switching damper in the bathroom ventilation drying heater of 1st Embodiment, FIG. 9 is the inside of the bathroom in the bathroom ventilation drying heater of 1st Embodiment. Next, an operation example of the bathroom ventilation dryer 1A according to the first embodiment will be described with reference to the drawings.

  In the drying operation mode, the controller 81A sets the air path switching damper 6A to the circulation ventilation position shown in FIG. 7, drives the circulation ventilation fan motor 26A to rotate the impeller 25A, and energizes the heater 5.

  In the bathroom ventilation dryer 1A, when the impeller 25A rotates, the air in the bathroom 100 is sucked into the circulation ventilation inlet 20A from the inlet grill 40A of the front panel 4A.

  In the dry operation mode, since the air path switching damper 6A is in the circulation ventilation position, the blowout air path 28A includes a circulation air path communicating from the circulation ventilation suction port 20A to the first air outlet 21A and the second air outlet 22A. Both of the ventilation air paths communicating from the circulation ventilation inlet 20A to the ventilation outlet 23A are formed.

  Thereby, a part of air RA of the bathroom 100 sucked from the circulation ventilation suction port 20A by the rotation of the impeller 25A flows to the first air outlet 21A and the second air outlet 22A. Further, the remaining air in the bathroom 100 sucked from the circulation ventilation inlet 20A flows to the ventilation outlet 23A, passes through the exhaust duct 102, and is exhausted to the outside as the exhaust EA from the outdoor grill 102a.

  In the drying operation mode, the air flowing through the first air outlet 21A is heated by the heater 5 so that the hot air HA is blown out from the first air outlet grill 41A of the front panel 4A. Since the air flowing through the second air outlet 22A does not pass through the heater 5, air A corresponding to the room temperature is blown out from the second air outlet grill 42A of the front panel 4A.

  In the bathroom ventilation dryer 1A, the air blown from the first outlet grille 41A spreads in the longitudinal direction of the land pipe 105 and the direction orthogonal to the land pipe 105.

  However, the bathroom ventilation drying / heating machine 1A is arranged so that the longitudinal direction of the first blower outlet grill 41A is orthogonal to the land pipe 105, so that the air blown from the first blower grill 41A is mainly used. It spreads in a direction orthogonal to the land re-pipe 105.

  For this reason, warm air is applied to the whole of the width direction with respect to an object to be dried such as clothes hung on the land pipe 105 in the vicinity immediately below the first outlet grille 41A. On the other hand, the hot air blown out from the first outlet grille 41A is directly applied to an object to be dried hung on the land pipe 105 at a position away from directly below the first outlet grille 41A. Hard to hit.

  In the bathroom ventilation dryer 1A, the air A blown out from the second outlet grille 42A is on the side where the second outlet grille 42A is provided with respect to the first outlet grille 41A by the rectifying plate 43A. It is directed to the wall surface 106 a of the bathroom 100.

  As a result, as shown in FIG. 9A, the air A blown from the second outlet grille 42A in the drying mode is applied to one wall surface 106a of the bathroom 100, and the wall surface 106a as shown by an arrow A1. It flows downward along. The air flowing downward along the wall surface 106a flows in the vicinity of the lower layer of the bathroom 100 mainly toward the other wall surface 106b, as indicated by an arrow A2.

  In the bathroom ventilation dryer 1A, the air RA sucked from the suction grill 40A causes a flow of circulating air in the bathroom 100, so the air flowing in the vicinity of the lower layer of the bathroom 100 toward the other wall surface 106b. Flows upward along the wall surface 106b as indicated by an arrow A3, and is sucked from the inlet grill 40A.

  As described above, in the bathroom ventilation dryer 1A, the air blown from the second outlet grille 42A is directed downward along the one wall surface 106a of the bathroom 100, and the vicinity of the lower layer of the bathroom 100 is moved to the other wall surface 106b. , And an upward air flow can be generated along the other wall surface 106b.

  Since the air blown from the first blower outlet grill 41A of the bathroom ventilation dryer 1A in the drying operation mode is warm air heated by the heater 5 and the relative humidity is lowered, the second blower grill Lighter than air blown from 42A.

  For this reason, the air blown out from the second blowout grille 42A, which is heavier than the air blown out from the first blowout grille 41A, flows to the lower layer of the bathroom 100, and the air is agitated throughout the bathroom 100. Wind flow can be generated.

  Thereby, the warm air blown out from the first outlet grille 41A is also near the object to be dried hung on the land re-pipe 105 at a position away from directly below the first outlet grille 41A, which is difficult to hit directly. An air flow can be generated.

  In the dry operation mode, when the ion generator 10 is driven, unheated air containing ions is blown out from the second outlet grille 42A. The air blown out from the second outlet grille 42 </ b> A flows to the lower layer of the bathroom 100, and a flow of air that stirs the air containing ions can be generated in the entire bathroom 100.

  As a result, while drying the clothes hung on the land re-pipe 105, air containing ions is applied to the entire plurality of clothes hung on the land re-pipe 105, thereby suppressing the growth of bacteria attached to the clothes. The deodorizing effect can be obtained.

  In the circulation ventilation operation mode, the control unit 81A sets the air path switching damper 6A to the circulation ventilation position shown in FIG. 7, drives the circulation ventilation fan motor 26A with the heater 5 not driven, and rotates the impeller 25A. Here, in the drying operation mode and the circulation ventilation operation mode described above, the opening degree of the air path switching damper 6A is set to the ventilation blower so that the ventilation ventilation operation mode increases the ventilation air volume, which is the air volume exhausted to the outdoors. You may change to the position where the opening degree of exit 23A becomes wide.

  In the bathroom ventilation dryer 1A, the air in the bathroom 100 is sucked into the circulation ventilation inlet 20A from the inlet grill 40A of the front panel 4A by rotating the impeller 25A.

  In the circulation ventilation operation mode, since the air path switching damper 6A is in the circulation ventilation position, a part of the air in the bathroom 100 sucked from the circulation ventilation suction port 20A is part of the first air outlet 21A and the second air outlet 22A. It flows to. Moreover, the remainder of the air of the bathroom 100 sucked in from the circulation ventilation inlet 20A flows to the ventilation outlet 23A and is exhausted outdoors.

  In the circulation ventilation operation mode, since the heater 5 is not driven, the air flowing through the first air outlet 21A is blown out from the first air outlet grill 41A of the front panel 4A according to the room temperature. Since the air flowing through the second air outlet 22A does not pass through the heater 5, air A corresponding to the room temperature is blown out from the second air outlet grill 42A of the front panel 4A.

  In the bathroom ventilation dryer 1A, as shown in FIG. 9B, even in the circulation ventilation operation mode, the air blown out from the second outlet grille 42A is moved downward along one wall surface 106a of the bathroom 100. It is possible to generate an air flow that faces the lower surface of the bathroom 100 toward the other wall surface 106b and moves upward along the other wall surface 106b.

  Thereby, even in the circulation ventilation operation mode, it is possible to generate a flow of air that stirs the air in the entire bathroom 100, and the air blown from the first outlet grille 41 </ b> A directly in the bathroom 100. Even in places where it is difficult to hit, an air flow can be generated.

  Therefore, the drying time of each wall surface, floor surface, etc. of the bathroom 100 can be shortened. In addition, since a part of the air in the bathroom 100 is exhausted to the outside and ventilation is performed, moisture and the like can be discharged to promote drying of each wall surface and floor surface of the bathroom 100.

  Even in the circulation ventilation operation mode, when the ion generator 10 is driven, unheated air containing ions is blown out from the second outlet grille 42A. The air blown out from the second outlet grille 42 </ b> A flows to the lower layer of the bathroom 100, and a flow of air that stirs the air containing ions can be generated in the entire bathroom 100.

  Thereby, the proliferation of a microbe can be suppressed and the generation | occurrence | production of mold | fungi can be suppressed by making the air containing ion hit the ceiling, the wall surface, and the whole floor surface of the bathroom 100. FIG.

  As another operation mode executed in the bathroom ventilation dryer 1A, in the heating operation mode, the air passage switching damper 6A is set to the circulation position shown in FIG. 6 to energize the heater 5, and the circulation ventilation fan motor 26A is turned on. Drives to rotate the impeller 25A.

  In the bathroom ventilation dryer 1A, the air in the bathroom 100 is sucked into the circulation ventilation inlet 20A from the inlet grill 40A of the front panel 4A by rotating the impeller 25A.

  In the heating operation mode, since the air path switching damper 6A is in the circulation position, substantially the entire amount of the air in the bathroom 100 sucked from the circulation ventilation inlet 20A flows to the first outlet 21A. In the heating operation mode, the air flowing through the first air outlet 21A is heated by the heater 5, so that warm air is blown out from the first air outlet grill 41A of the front panel 4A.

  In the heating operation mode, since the air path switching damper 6A is in the circulation position, the air in the bathroom 100 is not ventilated. Thereby, in the heating operation mode, the temperature in the bathroom 100 can be raised to a temperature suitable for bathing by circulating the air in the bathroom 100 while blowing hot air from the first outlet grille 41A. it can.

  Further, when the air path switching damper 6A is in the circulation position, the second air outlet 22A is blocked in addition to the ventilation air outlet 23A, so that air that does not pass through the heater 5 is not blown out. Thereby, even if it is the heating operation mode performed during bathing, the air which is not warmed by the heater 5 is not blown out, and the bather does not feel cold.

  Furthermore, when the air path switching damper 6A is in the circulation position, the second air outlet 22A is blocked by the backflow prevention portion 63A with respect to the ventilation air outlet 23A, so that the outside air is prevented from flowing back into the bathroom 100. Can do.

  In the ventilation operation mode, the air path switching damper 6A is set to the ventilation position shown in FIG. 8, the heater 5 is not driven, the circulation ventilation fan motor 26A is driven, and the impeller 25A is rotated.

  In the bathroom ventilation dryer 1A, the air in the bathroom 100 is sucked into the circulation ventilation inlet 20A from the inlet grill 40A of the front panel 4A by rotating the impeller 25A.

  In the ventilation operation mode, since the air path switching damper 6A is in the ventilation position, the first air outlet 21A and the second air outlet 22A are blocked, and the abbreviation of the air in the bathroom 100 sucked from the circulation ventilation air inlet 20A. The entire amount flows to the ventilation outlet 23A and is exhausted outdoors. Therefore, in the ventilation operation mode, steam and moisture in the bathroom 100 can be discharged to suppress dew condensation and the like, thereby suppressing the occurrence of mold.

  FIGS. 10-11 is operation | movement explanatory drawing which shows the operation | movement which replaces | exchanges an ion generator. In the ion generator 10, the electrode is consumed by the operation of generating ions. Therefore, the ion generator 10 is replaced at a predetermined timing. For example, the control unit 81A measures the time when the ion generator 10 is driven, and determines the replacement time of the ion generator 10 from the accumulated value of the time when the ion generator 10 is driven. When the control unit 81A determines that it is time to replace the ion generator 10, the control unit 81A notifies the operation unit 82 or the like.

  When the cover 401A is opened as shown by an arrow C1 in FIG. 10, the ion generator 10 is exposed from the front panel 4A, and the ion generator 10 can be attached and detached. By providing the cover portion 401A, the ion generator 10 can be attached and detached without removing the entire front panel 4A from the main body portion 3A.

  When the cover 401A is opened, the power is shut off by the shutoff switch 203A. This prevents the ion generator 10 from being driven while the ion generator 10 is exposed.

  By opening the cover portion 401A and operating the fixing portion 202A, the ion generator 10 can be detached from the attachment portion 201A. In addition, since electricity is supplied to the ion generator 10, it is electrically connected to the main body 3A side. Therefore, the presence or absence of electrical connection between the ion generator 10 and the main body 3A side is switched using a detachable connector or the like.

  The cover unit 401A is opened, the fixed unit 202A is operated, and the used ion generator 10 is removed from the mounting unit 201A as shown by an arrow D1 in FIG. A typical connection.

  A new ion generator 10 is attached to the attachment portion 201A from which the used ion generator 10 is removed as shown by an arrow D2 in FIG. 11, and fixed to the attachment portion 201A by a fixing portion 202A. Electrical connection with the main body 3A side is performed. Here, when the cover 401A is opened, the power is shut off by the shutoff switch 203A. Therefore, even if the ion generator 10 is electrically connected to the main body 3A, the ion generator 10 Electricity does not flow.

  Then, the cover 401A is closed as indicated by an arrow C2 in FIG. When the cover part 401A is closed, power is supplied by the shutoff switch 203A, and the bathroom ventilation dryer 1A can be operated.

  As described above, the ion generator 10 can be replaced without taking down the bathroom ventilation dryer 1A from the ceiling of the bathroom 100 that is the installation location. The ion generator 10 can be replaced by opening the cover 401A, and there is no need to remove the front panel 4A. Furthermore, since the power supply is shut off by opening the cover 401A, even if the operation of the switchboard for shutting off the power supply to the bathroom ventilation dryer / heater 1A is forgotten, ion generation occurs when the ion generator 10 is exposed. No electricity flows through the vessel 10.

  Thereby, replacement | exchange of the ion generator 10 is possible by simple operation, and the performance of the ion generator 10 can be maintained over a long period of time. Moreover, since the performance of the ion generator 10 can be maintained over a long period of time, it is not necessary to reduce the output of the ion generator 10, and the expected performance due to the action of ions can be exhibited. In particular, the effect can be exhibited not only in the airborne bacteria in the air but also in the removal of attached bacteria such as walls of the bathroom 100. Furthermore, it is possible to execute an operation mode in which ions are constantly generated.

For this reason, the air path switching damper 6A includes a brush 601 at the tip of the main air path switching unit 61A on the upstream side of the shaft 60A with respect to the air flow direction. The brush 601 is an example of a cleaning unit, and is displaced by drawing a circular arc locus 602 by the rotation operation of the air path switching damper 6A with the shaft 60A as a fulcrum.

  The bathroom ventilation dryer 1B supplies ions to the air blown from the first air outlet 21A and the second air outlet 22A. Therefore, the ion generator 10 causes the ion discharge part 10A to enter the air outlet 28A. And is installed in the circulation ventilation fan case 27A.

  Then, in order to clean the discharge portion 10A of the ion generator 10 with the brush 601, the ion generator 10 releases ions on the locus 602 of the brush 601 by the rotation operation of the air path switching damper 6A with the shaft 60A as a fulcrum. It is installed so that the part 10A is located.

  In this example, as shown by a solid line in FIG. 15, in the operation of moving the air path switching damper 6 </ b> A to the ventilation position, the inside of the circulation ventilation fan case 27 </ b> A where the brush 601 is in contact with the discharge portion 10 </ b> A of the ion generator 10. An ion generator 10 is installed on the lower surface.

<Operation Example of Bathroom Ventilation Dryer / Heater of Second Embodiment>
When the ventilation operation mode described above is executed, the brush 601 comes into contact with the discharge portion 10A of the ion generator 10 by the operation of moving the air path switching damper 6A to the ventilation position. Thereby, the discharge | release part 10A of the ion generator 10 is cleaned with the brush 601. FIG. In the ventilation operation mode, since the ion generator 10 is not driven, the brush 601 may be in contact with the discharge portion 10A of the ion generator 10.

  Note that when the 24-hour ventilation operation mode is executed, the air path switching damper 6A is stopped at the ventilation position, so that the discharge portion 10A of the ion generator 10 by the brush 601 cannot be sufficiently cleaned.

  Therefore, the ion generator 10 may be cleaned at a predetermined timing. For example, the control unit 81A measures the time when the ion generator 10 is driven, and determines the cleaning time of the ion generator 10 from the accumulated value of the time when the ion generator 10 is driven. When the control unit 81A determines that it is time to clean the ion generator 10, the control unit 81A notifies the operation unit 82 or the like.

  Moreover, it has the cleaning mode which moves 6 A of air path switching dampers to a ventilation position, and when the cleaning time comes, operation by the operation part 82 or automatically performs cleaning mode. Thereby, the ion generator 10 can be cleaned without attaching or detaching the ion generator 10 from the main body 3A, and the performance of the ion generator 10 can be maintained for a long period of time.

  The present invention is applied to a blower installed in a space for drying an object to be dried such as a bathroom.
