6 to 8 are explanatory views showing the operation of the air passage switching damper in the bathroom ventilation drying heater according to the first embodiment, and FIG. 9 shows the inside of the bathroom in the bathroom ventilation drying heater according to the first embodiment. Next, with reference to each figure, an operation example of the bathroom ventilation drying heater 1A of the first embodiment will be described.

In the dry operation mode, the control unit 81A sets the air passage 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 drying heater 1A, when the impeller 25A rotates, the air in the bathroom 100 is sucked into the circulation ventilation suction port 20A from the suction port grill 40A of the front panel 4A.

In the dry operation mode, the air passage switching damper 6A is in the circulation ventilation position. Therefore, in the outlet air passage 28A, the circulation air passage that communicates from the circulation ventilation suction port 20A to the first outlet 21A and the second outlet 22A. Both of the ventilation air passages communicating from the circulation ventilation suction port 20A to the ventilation outlet 23A are formed.

As a result, a part of the 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 outlet 21A and the second outlet 22A. Further, the rest of the air of the bathroom 100 sucked from the circulation ventilation suction port 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 dry operation mode, the air flowing through the first outlet 21A is heated by the heater 5, so that the warm air HA is blown out from the first outlet grill 41A of the front panel 4A. Since the air flowing through the second outlet 22A does not pass through the heater 5, the air A corresponding to the room temperature is blown out from the second outlet grill 42A of the front panel 4A.

In the bathroom ventilation drying heater 1A, the air blown out from the first outlet grill 41A spreads in the longitudinal direction of the land repipe 105 and in the direction orthogonal to the land repipe 105.

However, since the bathroom ventilation drying heater 1A is arranged so that the longitudinal direction of the first outlet grill 41A is orthogonal to the land repipe 105, the air blown out from the first outlet grill 41A is mainly. It spreads in the direction orthogonal to the land repipe 105.

Therefore, warm air is applied to the entire width direction of the object to be dried such as clothes hung on the land repipe 105 immediately below the first outlet grill 41A. On the other hand, for the object to be dried hung on the land repipe 105 located away from directly below the first outlet grill 41A, the warm air blown out from the first outlet grill 41A directly. It's hard to hit.

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

As a result, as shown in FIG. 9A, the air A blown out from the second outlet grill 42A in the drying mode is applied to one wall surface 106a of the bathroom 100, and the wall surface 106a is shown by the 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 shown by the arrow A2.

In the bathroom ventilation drying heater 1A, the air RA sucked from the suction port grill 40A creates a flow for circulating air in the bathroom 100, so that the air flowing near the lower layer of the bathroom 100 toward the other wall surface 106b. Flows upward along the wall surface 106b as shown by the arrow A3, and is sucked from the suction port grill 40A.

As described above, in the bathroom ventilation drying heater 1A, the air blown from the second outlet grill 42A goes downward along one wall surface 106a of the bathroom 100, and the vicinity of the lower layer of the bathroom 100 is the other wall surface 106b. It is possible to generate an upward flow of air along the other wall surface 106b.

In the dry operation mode, the air blown from the first outlet grill 41A of the bathroom ventilation drying heater 1A is warm air heated by the heater 5, and the relative humidity is lowered, so that the second outlet grill It is lighter than the air blown from 42A.

Therefore, the air blown out from the second outlet grill 42A, which is heavier than the air blown out from the first outlet grill 41A, flows to the lower layer of the bathroom 100 and agitates the air throughout the bathroom 100. Can create a flow of wind.

As a result, the warm air blown out from the first outlet grill 41A can be easily hit even in the vicinity of the object to be dried hung on the land repipe 105 located away from directly below the first outlet grill 41A. It can create a flow of air.

In the dry operation mode, when the ion generator 10 is driven, unheated air containing ions is blown out from the second outlet grill 42A. The air blown out from the second outlet grill 42A can flow to the lower layer of the bathroom 100, and can generate a flow of wind that agitates the air containing ions throughout the bathroom 100.

As a result, while drying the clothes hung on the land repipe 105, the air containing ions hits the entire clothes hung on the land repipe 105, thereby suppressing the growth of bacteria adhering to the clothes. , Deodorizing effect can be obtained.

In the circulation ventilation operation mode, the control unit 81A sets the air passage switching damper 6A to the circulation ventilation position shown in FIG. 7, sets the heater 5 as non-drive, and drives the circulation ventilation fan motor 26A to rotate the impeller 25A. Here, in the above-mentioned dry operation mode and circulation ventilation operation mode, the opening degree of the air passage switching damper 6A is ventilated so that the ventilation air volume, which is the air volume exhausted to the outside, is larger in the circulation ventilation operation mode. It may be changed to a position where the opening degree of the outlet 23A becomes wider.

In the bathroom ventilation drying heater 1A, the impeller 25A rotates, so that the air in the bathroom 100 is sucked into the circulation ventilation suction port 20A from the suction port grill 40A of the front panel 4A.

In the circulation ventilation operation mode, since the air passage switching damper 6A is in the circulation ventilation position, a part of the air of the bathroom 100 sucked from the circulation ventilation suction port 20A is a part of the first outlet 21A and the second outlet 22A. Flow to. Further, the rest of the air in the bathroom 100 sucked in from the circulation ventilation suction port 20A flows to the ventilation outlet 23A and is exhausted to the outside.

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

In the bathroom ventilation drying heater 1A, as shown in FIG. 9B, even in the circulation ventilation operation mode, the air blown from the second outlet grill 42A downwards along one wall surface 106a of the bathroom 100. It is possible to generate an upward air flow along the other wall surface 106b, facing the lower layer of the bathroom 100 toward the other wall surface 106b.

As a result, even in the circulation ventilation operation mode, it is possible to generate a flow of air that agitates the air in the entire bathroom 100, and the air blown out from the first outlet grill 41A directly in the bathroom 100. Air flow can be created even in places where it is difficult to hit.

Therefore, it is possible to shorten the drying time of each wall surface, floor surface, etc. of the bathroom 100. Further, since a part of the air in the bathroom 100 is exhausted to the outside for ventilation, it is possible to discharge moisture and the like to promote the drying of each wall surface, floor surface, etc. 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 grill 42A. The air blown out from the second outlet grill 42A can flow to the lower layer of the bathroom 100, and can generate a flow of wind that agitates the air containing ions throughout the bathroom 100.

As a result, the air containing ions can be applied to the entire ceiling, wall surface, and floor surface of the bathroom 100 to suppress the growth of bacteria and suppress the growth of mold.

As another operation mode executed by the bathroom ventilation drying heater 1A, in the heating operation mode, the air passage switching damper 6A is set to the circulation position shown in FIG. 6, the heater 5 is energized, and the circulation ventilation fan motor 26A is used.

In the bathroom ventilation drying heater 1A, the impeller 25A rotates, so that the air in the bathroom 100 is sucked into the circulation ventilation suction port 20A from the suction port grill 40A of the front panel 4A.

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

In the heating operation mode, since the air passage switching damper 6A is in the circulation position, the air in the bathroom 100 is not ventilated. As a result, in the heating operation mode, the air in the bathroom 100 is circulated while blowing warm air from the first outlet grill 41A, so that the temperature in the bathroom 100 can be raised to a temperature suitable for bathing. can.

Further, when the air passage switching damper 6A is in the circulation position, the second outlet 22A is blocked in addition to the ventilation outlet 23A, so that the air that does not pass through the heater 5 is not blown out. As a result, even in the heating operation mode executed during bathing, the air not heated by the heater 5 is not blown out, and the bather does not feel cold.

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

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

In the bathroom ventilation drying heater 1A, the impeller 25A rotates, so that the air in the bathroom 100 is sucked into the circulation ventilation suction port 20A from the suction port grill 40A of the front panel 4A.

In the ventilation operation mode, since the air passage switching damper 6A is in the ventilation position, the first outlet 21A and the second outlet 22A are blocked, and the abbreviation for the air in the bathroom 100 sucked from the circulation ventilation suction port 20A. The entire amount flows to the ventilation outlet 23A and is exhausted to the outside. Therefore, in the ventilation operation mode, steam and moisture in the bathroom 100 can be discharged to suppress dew condensation and the like, and the generation of mold can be suppressed.

10 to 11 are operation explanatory views showing an operation of exchanging an ion generator. In the ion generator 10, the electrodes are 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 for driving the ion generator 10 and determines the replacement time of the ion generator 10 from the cumulative value of the time for driving the ion generator 10. When the control unit 81A determines that it is time to replace the ion generator 10, the operation unit 82 or the like notifies the control unit 81A.

<Structure example of bathroom ventilation drying heater of the second embodiment>
FIG. 15 is a configuration diagram showing an example of the bathroom ventilation drying heater according to the second embodiment, and is a side view showing the internal configuration of the bathroom ventilation drying heater according to the second embodiment. The machine 1B includes a cleaning means for cleaning the functional factor generating portion as a performance maintaining means for maintaining the performance of the functional factor generating portion that generates the functional factor released into the air blown into the room.

The bathroom ventilation drying heater 1B includes an ion generator 10 as a functional factor generator. The ion generator 10 generates and releases ions as a functional factor to remove bacteria. Therefore, the ions mainly function as an air purifying factor that purifies the air, and the ion generator 10 functions as an air purifying factor generator that generates and releases ions.

The bathroom ventilation drying heater 1B cleans the ion generator 10 by the operation of the air passage switching damper 6A. Therefore, the air passage switching damper 6A is provided with a brush 601 at the tip of the main air passage switching portion 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 means, and is displaced by drawing an arc locus 602 by the rotational operation of the air passage switching damper 6A with the shaft 60A as a fulcrum.

Since the bathroom ventilation drying heater 1B supplies ions to the air blown out from the first outlet 21A and the second outlet 22A, the ion generator 10 passes the ion discharging portion 10A into the blowing air passage 28A. It is exposed to and installed in the circulation ventilation fan case 27A.

Then, in order to clean the emission portion 10A of the ion generator 10 with the brush 601 the ion generator 10 emits ions on the locus 602 of the brush 601 by the rotational operation of the air passage switching damper 6A with the shaft 60A as the fulcrum. It is installed so that the portion 10A is located.

The ion generator 10 is installed on the lower surface.

<Operation example of the bathroom ventilation drying heater of the second embodiment>
When the above-mentioned ventilation operation mode is executed, the brush 601 comes into contact with the emission unit 10A of the ion generator 10 by the operation of moving the air passage switching damper 6A to the ventilation position. As a result, the emission unit 10A of the ion generator 10 is cleaned by the brush 601. In the ventilation operation mode, since the ion generator 10 is not driven, the brush 601 may come into contact with the emission unit 10A of the ion generator 10.

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

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

Further, it has a cleaning mode for moving the air passage switching damper 6A to the ventilation position, and when the cleaning time comes, the operation unit 82 operates or automatically executes the cleaning mode.
