Description

Bathroom dryer

The present invention relates to a bathroom dryer that is installed in a ceiling of a bathroom and that ventilates, dries, and warms the bathroom.

In the past, there have been many proposals for bathroom dryers that ventilate, dry, and warm the air in the bathroom. The bathroom dryer is placed on the ceiling or side wall of the bathroom, and the bathroom side is covered by a panel for creativity and safety. In the gap between the panel and the bathroom dryer body, the moisture of the bathroom is easy to stay and is prone to mildew. Therefore, various proposals have been made regarding suppression of mildew in the panel. Further, as a countermeasure against mildew around the air outlet, it is necessary to improve the circulation of the surrounding air, but several improvements have been made regarding the improvement of the air circulation of the air outlet.

The multi-chamber bathroom dryer has two functions of ventilating, drying, and warming the bathroom, and functions of ventilating the other chamber. When each function is operated independently, at least two air passages are required. Therefore, the bathroom dryer for a multi-room is larger than the bathroom dryer for one of the bathrooms, and the installation workability and the maintainability are poor. Regarding the bathroom dryer for multi-room use, various proposals have been made to improve the workability and maintainability.

For example, the ventilating room heater for a bathroom proposed in Patent Document 1 is formed to have a lower surface located at a position facing the opening of the body, and protrudes from the lower side to the outer side of the outer peripheral frame and plugs the lower surface. The manner between the ceiling surfaces forms a square frame-shaped louver frame provided with a suction port from which air is taken in the bathroom. By providing the suction port, the air is prevented from staying in the space formed between the louver frame and the ceiling, and the internal space of the louver frame is dried by the air flow, thereby suppressing mold. In addition, when the air is taken in from the suction port of the louver frame, the air blown to the center of the bathroom becomes a circulation flow that rises along the wall surface of the bathroom after hitting the floor and then flows along the ceiling and is sucked by the suction port. The circulation of the bathroom air.

Further, the three-warm device proposed in Patent Document 2 uses a control device to increase the air volume of the fan at the start of operation, thereby improving the circulation of the bathroom air, uniformizing the temperature distribution, performing high-efficiency humidification, and suppressing dew condensation water. Attachment to the blowout. Further, an opening is provided on the side surface of the air passage where the air outlet of the louver is provided, and the amount of wind is increased by the induced flow. By using the induced flow, the air around the air outlet is sucked, and the positive circulation of the air around the air outlet is promoted, and the performance is improved by the increase in the amount of air.

Further, in the air circulation device proposed in Patent Document 3, the nozzle is provided at the tip end portion of the pipe through which the air blown from the electric fan passes, and the venturi is placed at the tip end portion of the nozzle via the gap, thereby increasing the air volume and Improve air circulation in air conditioning space.

However, the bathroom dryer proposed in Patent Document 1 has a problem that air is liable to stay in the internal space close to the other side surfaces because it is opened only on the opposite side surfaces of the square louver frame. Further, an air passage for forming an air outlet is disposed in the internal space around the air outlet in the louver frame, and air may be retained. Moreover, the underside of the louver is a curved surface, which has a problem of poor cleanability. Further, regarding the circulation of the air in the entire bathroom, since only the side faces of the louver frames are opposed to each other, there is a problem that the circulation of the air around the unopened side faces is poor.

Further, in the three-warm device described in Patent Document 2, since the fan is controlled by the control device, the amount of wind is increased, so that the noise is increased. Further, in the case where the inductive flow is used, the side surface on the side of the suction port of the fan in the frame of the air outlet is short-circuited by the air, so that the opening cannot be provided, and the circulation of the air around the side surface cannot be improved. The problem of less induced flow.

The air circulation device described in Patent Document 3 is provided with a nozzle for generating an induced flow, and a large space required for providing a nozzle is required in the air blowing portion. Moreover, there is a problem that the cost is increased due to the provision of the nozzle.

The present invention has been made in view of the above problems, and an object thereof is to provide a bathroom dryer capable of suppressing mildew generated on the back side of a creative panel and a bottom plate of a circulation unit, and being small and capable of being low. The noise increases the amount of air blown, which improves the circulation of the bathroom air, improves the temperature distribution of the bathroom floor, and improves uneven drying.

In order to solve the above problems and achieve the object, the present invention is characterized in that the present invention comprises a circulation unit formed by a casing and a bottom plate, a circulation suction port facing downward and a guide lattice plate being blown downward, and a ventilation connection port is provided upward, and is internally provided. The utility model further comprises a circulation air passage which is provided with a circulation fan, a windshield and a heating part which opens and closes the ventilation connection port, and is disposed on a ceiling of the bathroom; the ventilation unit has a ventilation air passage provided with an exhaust port, and is connected with the circulation unit a ventilation port connection; the creative panel is provided with a gap between the ceiling and the lower outer edge portion of the circulation unit and covering the lower surface of the circulation unit; and the induced flow opening is disposed in the configuration The downstream side of the circulation air passage of the heating portion and the blowing guide lattice plate induce the surrounding air into the blown lattice plate.

Since the bathroom dryer of the present invention covers the underside of the circulation unit including the circulating suction port of the bathroom air with a gap between the gaps through the gap, the air in the gap space of the back side of the creative panel is sucked from the circulation suction port, and the back of the creative panel is reduced. The retention of air on the side. Further, the suction airflow is used to dry the back side of the creative panel and the bottom plate of the circulation unit, thereby suppressing mold. Further, by using the induced flow induced by blowing out the guide lattice, the periphery of the grid plate is blown to promote circulation of air, and mold resistance can be suppressed.

Further, since the bathroom air is taken in from the outer edge portion of the creative panel, the air circulation of the bathroom is excellent, and the amount of air blown is increased by the induced flow with low noise, and the floor temperature distribution of the bathroom and the drying unevenness of the bathroom are improved.

The bathroom dryer of the embodiment has five operation modes of ventilation, drying, cool air, air drying, and warm room, and can be switched by the remote controller. Further, in a bathroom dryer for a multi-chamber, it is possible to perform air exchange in a different room from the bathroom at the same time as the above-described operation.

In the ventilation operation, in the case of a bathroom dryer for one room, the circulation fan is operated, and the air of the bathroom is discharged to the outside. In the case of a bathroom dryer for a multi-chamber, the ventilation fan is operated, and the air of both the bathroom and the other room is discharged to the outside.

In the dry operation, the air blown from the bathroom when the circulating fan is operated is branched to the circulation side and the ventilation side by the windshield, and the air branched to the circulation side is heated by the heating portion, and the air is blown to the bathroom while being heated to the outside. The air that is branched to the bathroom on the ventilation side is discharged to dry the bathroom. At this time, the opening size of the windshield is adjusted in such a manner that the circulating air volume is more than the ventilation air volume. In the case of a multi-chamber bathroom dryer, the ventilation fan is operated to discharge air from both the bathroom and the other chambers.

In the cool air operation, the windshield is used to divert the air sucked from the bathroom when the circulating fan is running to the circulation side and the ventilation side, and then the air branched to the circulation side is sent to the bathroom, and is discharged to the outside to the ventilation side. The air in the bathroom is exhausted. In the cool air, it is not heated by the heating part, and the circulating air is sent to the bathroom at room temperature. At this time, the opening size of the windshield is adjusted in such a manner that the circulating air volume is more than the ventilation air volume. In the case of a multi-chamber bathroom dryer, the ventilation fan is operated to discharge air from both the bathroom and the other chambers.

In the air drying operation, the windshield is used to divert the air sucked from the bathroom to the circulation side and the ventilation side when the circulating fan is operated, and then the air branched to the circulation side is sent to the bathroom while discharging to the outside to the ventilation side. The air in the bathroom is used to dry the bathroom. At this time, the opening size of the windshield is adjusted in such a manner that the amount of ventilation air is larger than the amount of circulating air. In the case of a multi-chamber bathroom dryer, the ventilation fan is operated to discharge air from both the bathroom and the other chambers. The air drying operation is different from the drying operation, and the bathroom is dried by air supply and ventilation without using warm air. Although the drying time is longer than the normal drying operation, it is energy-saving.

In the greenhouse operation, the air sucked from the bathroom when the circulating fan is operated flows to the circulation side by the windshield, and is heated by the heating unit, and then air is blown into the bathroom to perform warm room. In the case of a bathroom dryer for one room, the ventilation function is stopped during the warm room, but in the case of a bathroom dryer for a multi-chamber, if the ventilation fan is operated, the other room can be ventilated.

In order to operate in the above five operation modes, it is necessary to form four air passages in the circulation air passage, and to form the respective air passages in accordance with the rotational (oscillating) position of the rotary windshield as the windshield. The details of the rotational position of the rotary windshield in each operation mode and the formation of the air passage will be described in the description of the embodiment.

Hereinafter, embodiments of the bathroom dryer of the present invention will be described in detail based on the drawings. Further, the present invention is not limited by the embodiment.

The cross-sectional view of the downstream side of the circulation air passage when the rotational position of the windshield is set to the dry and cool air position, and the fourth section shows the cross section of the downstream side of the circulation air passage when the rotational position of the windshield is the air-drying position. Fig. 5 is a cross-sectional view showing the downstream side of the circulation air passage when the rotational position of the windshield is the warm room position, and Fig. 6 is a perspective view of the blown guide lattice plate of the first embodiment, and Fig. 7 is a view showing the Fig. 8 is a cross-sectional view showing the flow of air in the air passage of the bathroom dryer according to the first embodiment, and Fig. 9 is a sectional view showing the flow of the air in the bathroom dryer according to the first embodiment. A cross-sectional view of the flow of air blowing around the guide grid.

As shown in Fig. 1, the bathroom dryer 91 of the first embodiment has a circulation air passage 2a for ventilating, drying, and warming the bathroom, and a ventilation air passage 2b in the formed casing 16A. It is formed in an exhaust pipe connecting member 22 for performing air exchange in a bathroom. The exhaust pipe connecting member 22 as a ventilation unit is connected to the ventilation connecting port 9 of the circulation air passage 2a.

The circulation air passage 2a is formed by the outer casing 16A and the circulation orifice (bottom plate) 17, and is disposed with the circulating air suction port 4 of the bathroom air and the circulation air outlet (blowing guide grid) 8 facing downward, and is disposed on the downstream side upward. The gas connection port 9 is disposed on the inner upstream side by the circulation fan 5 driven by the motor M1, and the rotary windshield 6 and the heating unit 7 are disposed on the inner downstream side. The circulation air passage 2a including the circulation fan 5, the rotary damper 6, and the heating portion 7 is referred to as a circulation unit 91A.

The exhaust pipe connecting member 22 as the ventilating means forms the ventilating air passage 2b such that the exhaust direction becomes the side (the right direction in FIG. 1), and the exhaust port 21 opens in the lateral direction. When the exhaust pipe is connected to the exhaust port 21, ventilation along the chamber can be performed.

The filter 20 that filters out dust in the air is disposed on the upstream side of the circulation suction port 4. The lower side of the bathroom dryer 91 is covered with a creative panel 14. The control unit 15 and the power supply connection unit (not shown) are disposed on the upper side of the motor M1. The control unit 15 is connected to a remote controller (not shown) via a communication line, and the remote controller outputs an operation command to the control unit 15.

The ventilation connection port 9 is provided in the ceiling of the casing 16A, and air flows from the circulation air passage 2a through the ventilation connection port 9 to the ventilation air passage 2b. The circulation air passage 2a is formed by the outer casing 16A and the circulation orifice (bottom plate) 17, and is formed in a box shape in which the circulation suction port 4 and the ventilation connection port 9 are opened downward. The ventilation connecting port 9 is in communication with the ventilation air passage 2b when the rotary windshield 6 is opened. A shaft through hole (not shown) through which the rotating shaft of the motor M1 passes is provided in the outer casing 16A. Further, an insertion opening for inserting the holding members holding the heating portion 7 and the rotary windshield 6 is provided on the side plate of the outer casing 16A.

The circulation fan 5 is a single-suction type centrifugal fan, and is disposed on the upstream side of the circulation air passage 2a so as to face the circulation suction port 4. The air blown from the circulation fan 5 is branched to the downstream side of the circulation air passage 2a flowing from the heating unit 7 to the circulation air outlet 8 and the ventilation air passage 2b passing through the ventilation connection port 9 by the rotary windshield 6. The motor M1 is disposed on the upper side of the circulation air passage 2a.

The heating unit 7 is provided with a plurality of heat generating bodies, for example, at intervals, or a plurality of heat radiating fins are provided in the heat generating body, and the air passage is formed around the heat generating body or the heat radiating fin, and is configured to allow air to pass through the air passage to dissipate heat. An electric heater or an electric heater in which an electric insulator and a heat conductor are disposed in a surrounding heat generating body are housed in a metal pipe.

The heating unit 7 is disposed at the most downstream of the circulation air passage 2a. In order to suppress overheating of the heating unit 7, a PTC (Positive Temperature Coefficient) heater can be used. Since the PTC element is used as a heating element when the PTC heater reaches a predetermined temperature (the temperature of the ritual temperature), it has a self-temperature control function, is excellent in safety, and does not require temperature control, and is low in cost.

As shown in Fig. 6, the circulation air outlet (blowing guide grid) 8 is a rectangular duct (reduced) air passage (the air passage area is reduced toward the downstream side). The air passage area is reduced by bending the side plates on the long side of the air passage frame. The blown guide grid plate 8 is disposed on the downstream side of the circulation air passage 2a where the heating unit 7 is disposed with a gap therebetween, and the air passage area before the reduction is made larger than the air passage area on the downstream side of the circulation air passage 2a where the heating unit 7 is disposed. Big.

The gap between the downstream side of the circulation air passage 2a and the blowing guide grid plate 8 serves as an induced flow opening 31 for inducing the air around the guide grid plate 8 to be blown out of the guide grid plate 8. The induced flow opening 31 is perpendicular to the air blowing direction on the downstream side of the circulation air path 2a. The air passage area of the downstream side of the circulation air passage 2a is made larger than the air passage area on the downstream side of the circulation air passage 2a, and the induced flow opening 31 is perpendicular to the air blowing direction on the downstream side of the circulation air passage 2a, thereby not being provided. With the nozzle, the induced flow can be efficiently generated.

Further, the blow-out guide grid 8 has wings arranged in parallel so that the blown air can be directed in a fixed direction. In addition, the rotating shaft can also be placed on the wing plate, and the direction can be adjusted by adjusting the direction to adjust the wind direction.

The rotary damper 6 is disposed on the lower side of the ventilating connection port 9 between the circulation fan 5 and the heating unit 7 of the circulation air passage 2a, and is formed in a plate shape in which the front end portion and the base end portion are flat and the intermediate portion is curved. As shown in Fig. 7, the rotary windshield 6 is rotated about the windshield rotation shaft 23 provided at the base end portion. The sector gear 24 is fixed to the windshield shaft 23 and the side portion of the rotary windshield 6, and the rotary windshield 6 can be rotated by rotating the sector gear 24.

The rotary windshield 6 is driven by a speed reducer combined with a sector gear 24 and a pinion gear 25. The pinion gear 25 is rotated by, for example, a driving means such as a stepping motor, and the rotary windshield 6 is rotated and positioned via the sector gear 24, and a part of the circulation air passage 2a and/or the ventilation air passage 2b is formed.

The rotary windshield 6 is rotatable in a clockwise direction to be in contact with the top plate of the outer casing 16A to close the position of the ventilation connection port 9, and, in the counterclockwise direction, is rotatable to contact the circulation orifice (base plate) 17 to close the cycle. The downstream side of the air passage 2a and the upstream side of the circulation air passage 2a communicate with the ventilation connecting port 9 to have a rotatable angular range (about 30°).

The rotational positioning of the rotary windshield 6 is performed by a positioning control that rotates the rotary windshield 6 in a clockwise or counterclockwise direction over a range of rotatable angles to rotate it to a fifth or second rotation stop. After the starting point is determined, the rotary windshield 6 is rotated to the upstream side of the circulation air passage 2a and the downstream side of the circulation air passage 2a and the ventilation connection port 9 as shown in Fig. 3 or Fig. 4 The location where both sides are connected.

The creative panel 14 is attached to the outer casing 16A or the ceiling so as to cover the exposed portion of the bathroom of the outer casing 16A. The creative panel 14 is formed flat and is attached to the top surface and the lower outer edge portion of the circulation unit 91A via the gap, and the outer circumferential side wall of the creative panel 14, and draws in the bathroom air from the gap in the entire circumference of the creative panel 14. . The surface of the creative panel can be easily cleaned by forming the creative panel 14 into a flat shape.

The control unit 15 includes a memory element that stores a predetermined control program, and individually controls the circulation fan 5, the heating unit 7, and the rotary windshield 6 in response to an operation command input from the remote controller, and causes the bathroom dryer 91 to ventilate. Operation, drying operation, etc.

As described above, the bathroom dryer 91 of the first embodiment supports the rotary windshield 6 on one side by the windshield rotation shaft 23 provided at the proximal end portion, and the rotation angle is reduced, whereby the circulation air passage can be suppressed. The height of 2a allows the bathroom dryer 91 to be reduced in size and weight. Moreover, the circulating air volume and the ventilation air volume can be adjusted by being positioned and held in the middle of the rotation angle range.

Next, the ventilation operation, the drying operation, the cool air operation, the air drying operation, and the warm room operation of the bathroom dryer 91 according to the first embodiment will be described with reference to Figs. 2 to 5 . As shown in Fig. 2, in the ventilating operation, the tip end of the rotary damper 6 swings in a counterclockwise direction to a position in contact with the circulation orifice (base plate) 17, and is positioned to block the heating portion 7 side of the circulation air passage 2a ( On the downstream side, the circulation air passage 2a is connected to the ventilation air passage 2b via the ventilation connection port 9.

The air in the bathroom in which the bathroom dryer 91 is installed passes through the circulation suction port 4, flows through the circulation air passage 2a, and is exhausted from the exhaust port 21 to the outside, thereby ventilating the bathroom.

In the drying operation, as shown in Fig. 3, the front end of the rotary windshield 6 is not in contact with the top plate of the outer casing 16A and the circulation orifice (base plate) 17, and is positioned at the top plate and the circulation orifice (bottom plate) from the outer casing 16A. The intermediate position is close to the position of the top plate of the outer casing 16A. Therefore, the air can flow from the ventilation connection port 9 to the ventilation air passage 2b and the air passages on the downstream side of the circulation air passage 2a where the heating unit 7 is disposed. At the same time, the heating unit 7 is energized.

In the drying operation, the bathroom air that has been blown from the circulation fan 5 and flows into the circulation air passage 2a passes through the heating unit 7, and is then blown out from the circulation air outlet 8 into the bathroom, and a part of the air is connected to the ventilation air passage through the ventilation connection port 9 2b flows in, and is exhausted from the exhaust port 21 to the outside. In the dry operation, the air is blown to the bathroom while the air is blown, and the bathroom or the clothes can be made dry, and the bathroom dryer 91 can be used as a warm air dryer.

In the cool air operation, as shown in Fig. 3, the front end of the rotary windshield 6 is also not in contact with the top plate of the outer casing 16A and the circulation orifice (base plate) 17, and is positioned at the top plate and the circulation orifice (base plate) from the outer casing 16A. The intermediate position of 17 is near the position of the top plate of the outer casing 16A. As a result, air can flow from the ventilation connection port 9 to the air passages of the ventilation air passage 2b and the downstream of the circulation air passage 2a where the heating unit 7 is disposed. At the same time, the circulation fan 5 starts to operate, and unlike the drying operation, the heating unit 7 is not energized.

In the cool air operation, the bathroom air that is blown from the circulation fan 5 and flows into the circulation air passage 2a is blown out from the circulation air outlet 8 into the bathroom, and a part of the air is blown from the ventilation connection port 9 to the ventilation air passage 2b, and then exhausted. The port 21 is vented to the outside. In the cool air operation, one side of the bathroom is ventilated while the air is being supplied, and the heat of the bathroom can be exhausted.

In the wind drying operation, as shown in Fig. 4, the front end of the rotary windshield 6 is also not in contact with the top plate of the outer casing 16A and the circulation orifice (base plate) 17, and is positioned from the top plate of the outer casing 16A and the circulation orifice (the bottom plate). The intermediate position of 17 is close to the position of the circulation orifice (bottom plate) 17 side. Therefore, air can flow from the ventilation connecting port 9 to the air passages of the ventilation air passage 2b and the downstream of the circulation air passage 2a where the heating unit 7 is disposed. At the same time, the circulation fan 5 starts to operate, and unlike the drying operation, the heating unit 7 is not energized.

In the air drying operation, the air in the bathroom that has flowed from the circulation fan 5 to the circulation air passage 2a passes through the heating unit 7, and is blown out from the circulation outlet 8 into the bathroom, and a part of the air is connected from the ventilation connection port 9 to the ventilation air passage 2b. It flows in and is exhausted from the exhaust port 21 to the outside. In the air drying operation, unlike the drying operation, since the heating unit 7 is not energized, air is blown into the bathroom while still being in the air temperature in the bathroom. The room temperature is sent to the bathroom, and the air is ventilated to make the bathroom or clothing dry. In the air drying operation, although the drying speed is slower than the drying operation, since the heating unit 7 is not energized, the drying in the bathroom can be performed with a small power consumption.

In the greenhouse operation, as shown in Fig. 5, the rotary windshield 6 is rotated to a position in contact with the top plate of the outer casing 16A, and the ventilation connection port 9 is plugged, and the air can only flow to the circulation air passage continuous with the circulation air outlet 8. The downstream of 2a flows in. At the same time, the circulation fan 5 starts to operate, and the heating unit 7 is energized.

In the greenhouse operation, the bathroom air that has been blown from the circulation fan 5 and flows into the circulation air passage 2a passes through the heating unit 7, and is then blown out into the bathroom. After the air passing through the heating unit 7 is heated, it is blown out into the bathroom as warm air, and a warm room in the bathroom can be performed.

Next, the flow of the intake air of the bathroom dryer 91 of the first embodiment will be described. As shown in FIGS. 1 and 8, the creative panel 14 has a gap 30 between the ceiling and the lower outer edge portion of the circulation unit 91A, and is disposed to cover the lower surface of the circulation unit 91A, and the air of the bathroom is circulated by the fan 5. After the suction, the gap 30 flows into the gap space 33 between the creative panel 14 and the circulation orifice (bottom plate) 17. The air in the bathroom that has flowed into the gap space 33 is sucked by the circulation fan 5 from the circulation suction port 4, and then blown into the circulation air passage 2a, and then flows to the circulation air passage according to the rotational position of the rotary windshield 6 in each operation mode. The downstream of 2a and/or the ventilation air passage 2b flows in. The gap 30 is provided over the entire circumference of the creative panel 14, and the air of the bathroom can be taken in from the entire circumference. Therefore, the back surface of the creative panel 14 and the bottom plate 17 are dried by the flow of the wind, and the back surface of the creative panel 14 and the bottom plate 17 are prevented from being moldy.

Next, referring to Fig. 9, the induced flow during the drying operation, the cool air operation, the air drying operation, and the warm room operation will be described. The air blown from the circulation fan 5 is increased in speed when passing through the heating unit 7, and then blown out of the guide grid 8 to blow air into the bathroom. The induced flow system generated at this time is sucked from the gap 30, flows into the gap space 33 between the creative panel 14 and the circulation orifice (floor) 17, and then blows the air passage from the induced flow opening 31 toward the guide grid plate 8. The inside flows into the bathroom together with the air passing through the heating unit 7.

Further, since the gap 32 is divided into the circulation suction port 4 side and the partition plate 32 on the side of the blow guide grid 8 is provided in the circulation orifice (bottom plate) 17, the air does not open from the induced flow opening of the guide grid plate 8. 31 flows toward the circulation suction port 4 side, and the induced flow can be efficiently sucked into the outlet guide plate 8. By generating the induced flow, since the wind blows out around the guide grid 8, it is possible to suppress moldiness around the blown guide grid 8 on the back surface of the creative panel 14.

Further, since the amount of air blown to the bathroom is increased by the induced flow, the floor temperature distribution of the bathroom during the operation of the warm room is improved. Moreover, since the air volume is increased, the drying unevenness in the bathroom during the drying and air drying operation is also improved. Further, since the creative panel 14 has the gap 30 around the entire circumference of the ceiling, the circulation of the air of the ceiling is good, and the drying property of the ceiling surface is high.

Second embodiment

Fig. 10 is a cross-sectional view showing a second embodiment of the bathroom dryer of the present invention, and Fig. 11 is a top view showing the bathroom dryer according to the second embodiment. As shown in Fig. 10, in the difference between the bathroom dryer 92 of the second embodiment and the bathroom dryer 91 of the first embodiment, the ventilating unit 92B is used instead of the exhaust pipe connecting member 22, and the other chamber is ventilated. Features. The circulation unit 91A and the ventilation unit 92B are separable. Since the circulation unit 91A and the creative panel 14 have been described in the bathroom dryer 91 of the first embodiment, the description thereof is omitted.

The ventilation unit 92B has a casing 16B, and the ventilation air passage 2b is formed in the casing 16B. The ventilation air passage 2b is provided with the bathtub suction port 12a facing downward on the upstream side, and the exhaust port 13 is provided on the downstream side in the lateral direction, and a ventilation fan (centrifugal fan) 11 driven by the motor M2 is disposed inside. Further, on the upstream side of the ventilation fan 11, a ventilation hole 18 in which the ventilation inlet 10 is provided is disposed. The space between the bathroom suction port 12a and the ventilation port 18 becomes the ventilating chamber 12. In the ventilating chamber 12, the chamber suction port 12b is open.

The bathroom dryer 92 of the second embodiment can perform the ventilation operation, the drying operation, the air drying operation, the warm room operation, and the cool air operation in the same manner as the bathroom dryer 91 of the first embodiment. In the ventilation operation, the drying operation, the cool air operation, and the air drying operation, the circulation air passage 2a is connected to the ventilation air passage 2b, and the ventilation fan 11 starts to operate. As a result, the air of the bathroom in which the bathroom dryer 92 is installed passes through the circulation suction port 4, flows through the circulation air passage 2a, and is guided to the ventilation connection port 9 by the rotary windshield 6, and passes through the bathroom suction port of the ventilation air passage 2b. After 12a, the air is sucked into the ventilating chamber 12, and the air in the other chambers other than the bathroom is also sucked from the other chamber suction port 12b to the ventilating chamber 12, and the bathroom air and the other room air are ventilated by the ventilating fan 11 from the ventilating inlet 10. After inhalation, the air is exhausted from the exhaust port 13, so that the bathroom and the other room are ventilated.

Next, the multi-chamber ventilation function of the bathroom dryer 92 will be described with reference to Figs. 10 and 11 . As shown in Fig. 11, a plurality of (three) other chamber suction ports 12b are provided in the ventilation air passage 2b. The exhaust pipe from the other parts of the washing place, the toilet, and the like is connected to the respective room suction ports 12b, and when the ventilation fan 11 is operated, the air in the other room can be ventilated. Unused connectors can be closed and the number of rooms for ventilation can be arbitrarily selected.

The ventilation connection port 9 is communicated with the bathroom suction port 12a of the ventilating chamber 12, and is disposed below the exhaust port 13 in order to change the circulation fan 5 and the ventilation fan 11 from the circulation air passage 2a. The air-cooling path 2b is subjected to a dry operation of the air supply, a wind drying operation, and a cool air operation to prevent the air from flowing back to the other chamber suction port 12b. In order to prevent the air from flowing back to the other chamber suction port 12b, the backflow prevention damper may be provided in the other chamber suction port 12b. Moreover, the air volume control of the two fans is performed such that the intake air volume of the ventilation fan 11 is larger than the air volume that the circulation fan 5 sends to the ventilation air passage 2b.

The air that has flowed into the ventilation chamber 12 from the ventilation duct through the chamber suction port 12b passes through the ventilation inlet 10, is sucked by the ventilation fan 11, and is exhausted to the outside. When the bathroom dryer 92 is stopped, as shown in Fig. 5, as long as the rotary damper 6 is placed at the position where the ventilating port 9 is plugged, only the other chambers can be ventilated.
