Description

Bathroom dryer

The present invention relates to a bathroom dryer for use in a room for ventilating, drying, and heating a bathroom, and a bathroom dryer for ventilating a plurality of rooms other than the bathroom.

In the past, in the bathroom dryer, there is a bathroom dryer that ventilates, dries, and heats the bathroom, and a multi-chamber that can be used for ventilation in a room other than a bathroom such as a clothes dryer or a toilet. There are many proposals for bathroom dryers and about circulating air ducts and ventilation ducts.

The multi-chamber bathroom dryer has two functions of a function of ventilating, drying, and heating the bathroom, and a function 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 property and the maintainability are poor. In order to improve the workability and maintainability of the bathroom dryer for a multi-room, various proposals are made.

For example, the bathroom dryer proposed in Patent Document 1 includes a circulation unit that circulates heated air in a bathroom, a ventilation unit that ventilates the other chamber and exhausts the outside, and a circulation unit and a ventilation unit. The windshield unit is constructed between. The windshield unit has the function of switching the circulation air path and the ventilation air path and diverting it. By setting the windshield shaft to the center of the windshield, the air volume in the bathroom and the other chambers is stabilized, and the air volume can be distributed and the air volume can be adjusted.

Further, the bathroom dryer proposed in Patent Document 2 can be installed after the ventilation fan is provided in the bathroom, or can be independently installed. The bathroom dryer is configured such that the bottom plate constitutes a suction air for the bathroom, and is heated to return to the warm air circulation device in the bathroom, and the warm air circulation device is fixed in the bathroom in a state where the bottom plate opens the opening of the bathroom. With this configuration, the setup engineering and recovery status can be simplified. Moreover, it does not hinder the function of the ventilation fan.

Further, the bathroom dryer proposed in Patent Document 3 is disposed in a ventilating box of a ventilating unit that ventilates air in a room, and is disposed in a circulation unit that circulates, ventilates, and heats the bathroom air. Since the circulation unit is disposed in the ventilation box, the installation area of the ceiling can be made small.

However, in the bathroom dryer described in Patent Document 1, since the windshield rotating shaft is provided at the center of the windshield and the windshield is opened and closed, it is necessary to rotate the windshield by 90°. Therefore, a space for rotating the windshield is required on both sides of the air passage, and in the case where the ventilation opening is intended to secure a large area, the space required for the rotation of the windshield is also increased. Therefore, there is a problem that it is difficult to miniaturize the bathroom dryer. Further, since the windshield needs to be disposed on the air passage wall surface, both of the two air passages that open and close the windshield require a space required for the windshield to rotate. Moreover, since the windshield unit and the ventilation unit are attached to the side surface of the circulation unit, and the circulation unit is disposed in the ceiling opening, there is a problem that the detachability is poor when the ventilation unit is repaired.

In the bathroom dryer described in Patent Document 2, since the bathroom dryer is attached to the ceiling of the bathroom, the height and the installation area are required to be small. However, since the circulation air passage and the ventilation air passage are made to have different air passages, and the air passage shielding means is attached to the bathroom side on the ventilation air passage, it is difficult to make the height and the installation side of the bathroom side in the air passage. The area becomes smaller. Further, the shielding means is thinned in order to suppress the protruding size on the bathroom side, and a spring type shielding means is used, which has a problem of complicated structure.

Further, in the bathroom dryer described in Patent Document 3, a fan for circulating air for heating and heating in the bathroom is disposed in the main body of the ventilation fan for ventilating the bathroom and the other room. Since the circulation unit is constituted by the heating unit, it is difficult to ensure a sufficient opening area of the air passage of the connection bathroom and the ventilation fan. Since the gap between the unit case of the circulation unit and the body box of the ventilation fan is used as the air path of the connection bathroom and the ventilation fan, two windshields are required, which has a problem of complicated structure and high cost.

The present invention has been made in view of the above problems, and an object thereof is to provide a bathroom dryer which is small, light, and has good construction workability, and the width and depth of the ventilation unit (ventilating air passage) are located. The circulation unit (circulation air passage) is less than the width and depth, and improves the disassembly and maintainability. Although it is small, it ensures a sufficient opening area of the exhaust duct of the bathroom.

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 which is formed by a casing and a bottom plate, and is provided with a circulation suction port and a circulation air outlet downward, and a ventilation connection port is provided upward, and has a ventilation connection port therein. a circulation fan, a windshield that opens and closes the ventilation connection, and a circulation air passage of the heating unit are disposed on the ceiling of the bathroom; and the ventilation unit is provided with a bathtub suction port facing downward, and an exhaust port is provided laterally, and has an internal exhaust port The ventilation air passage of the ventilation fan is disposed, and the width and the depth are formed below the width and depth of the circulation unit, and are disposed on the circulation unit.

The bathroom dryer of the present invention is small, light, and has good installation property, and the width and depth of the ventilation unit (ventilation air passage) are located below the width and depth of the circulation unit (circulation air passage), and the disassembly and assembly property is improved. Maintainability, small, ensures ample opening area for the bathroom exhaust duct.

The bathroom dryer of the embodiment has five operation modes of ventilation, drying, cool air, air drying, and heating, and the operation mode 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 that is branched to the circulation side is heated by the heating portion, and the air is blown to the bathroom while being blown to the outside. The air in the bathroom on the ventilation side is diverted to dry in 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, the ventilation fan is operated to discharge the air from both the bathroom and the other chambers.

In the cool air operation, the windshield is used to divert the air taken in from the bathroom when the circulating fan is running to the circulation side and the ventilation side, and the air branched to the circulation side is sent to the bathroom, and the bathroom is discharged to the outside on the ventilation side. The air 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, the ventilation fan is operated, and the air from both the bathroom and the other chamber is discharged.

In the air drying operation, the air blown from the bathroom when the circulating fan is operated is branched to the circulation side and the ventilation side, and 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 dry for 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, the ventilation fan is operated, and the air from both the bathroom and the other chamber is discharged. 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 heating operation, the air sucked from the bathroom when the circulating fan is operated is flown to the circulation side by the windshield, and is heated by the heating unit, and then air is blown into the bathroom to perform heating. Although the ventilation function is stopped during heating in the case of one room, in the case of 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 to the embodiment.

The ventilation connection port 9 is provided in the partition plate 19. The partition plate 19 is disposed in the outer casing 16, whereby the circulation air passage 2a and the ventilation air passage 2b are separated, and the air flows from the circulation air passage 2a through the ventilation connection port 9 to the ventilation air passage 2b. The ventilation connecting port 9 communicates with the bathtub suction port 12a and is disposed below the exhaust port 13.

The circulation air passage 2a is formed by the outer casing 16, the partition plate 19, 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 communicates with the circulation air passage 2a when the rotary windshield 6 is opened. A shaft through hole (not shown) for passing through a rotating shaft of the motor M1 is provided to the outer casing 16. 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 16.

The ventilation air passage 2b is formed by the outer casing 16 and the partition plate 19, and is opened in the upstream ventilating chamber 12, the bathroom suction port 12a and the other chamber suction port 12b, and is formed in a box shape in which the exhaust port 13 is opened on the downstream side. The bathroom air is sucked into the ventilating chamber 12 through the circulation suction port 4, the circulation fan 6, the circulation air passage 2a, the ventilation connection port 9, and the bathroom suction port 12a. The air in the washbasin, the toilet, and the like is sucked into the ventilation chamber 12 through the ventilation pipe (not shown) and the other chamber suction port 12b. The exhaust port 13 is open to the outside using a ventilation pipe. A shaft through hole (not shown) for passing through a rotating shaft of the motor M2 is provided to the outer casing 16.

The circulation orifice (bottom plate) 17 is disposed on the bathroom side of the outer casing 16, and separates the circulation air passage 2a from the bathroom. At the circulation orifice (bottom plate) 17, the circulation suction port 4 of the air sucked into the bathroom is opened downward.

The ventilation port 18 is disposed in the ventilation air passage 2b, and is provided with a ventilation inlet 10 for inhaling the air of the ventilation chamber 12, and the ventilation chamber 12 takes in air from the bathtub suction port 12a and the other chamber suction port 12b.

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 by the rotary damper 6 to the circulation air passage 2a that flows from the heating unit 7 to the circulation air outlet 8 and the ventilation air passage 2b that passes through the ventilation connection port 9. The motor M1 is disposed on the upper side of the circulation air passage 2a.

The ventilation fan 11 is a single suction type centrifugal fan, and is disposed in the ventilation air passage 2b so as to face the ventilation inlet 10 . The ventilation fan 11 draws air into the bathroom through the ventilation connection port 9, the bathroom suction port 12a, the ventilation chamber 12, and the ventilation inlet 10, and draws in the bathroom through the other chamber suction port 12b, the ventilation chamber 12, and the ventilation suction port 10. After the air in the other chamber is removed, it is discharged from the exhaust port 13. The motor M2 is disposed on the upper side of the ventilation air passage 2b.

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 a flow path of the air is formed around the heat generating body or the heat radiating fins, and is configured to allow air to pass through the flow path 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 downstream of the circulation air passage 2a. In order to suppress overheating of the heating portion 7, it is preferable to use a PTC (Positive Temperature Coefficient); a self-controlled temperature heater. 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.

The circulation air outlet 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 arranged on the wing plate, and the adjustment direction is used to adjust the direction to control the wind direction.

The rotary windshield 6 is disposed on the lower side of the ventilation 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 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 partition plate 19 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 circulating air. The downstream side of the road 2a and the position where the upstream side of the circulation air passage 2a communicates with the ventilation connection port 9 have a rotatable angle 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, so that rotation to the fifth or second rotation of the rotation is stopped. After the starting point is determined, the rotary windshield 6 is rotated to the upstream side of the circulation air passage 2a shown in Fig. 3 or Fig. 4, the downstream side of the circulation air passage 2a, and the ventilation connection port 9 The location where the two sides are connected.

The creative panel 14 is attached to the outer casing 16 so as to cover the exposed portion of the outer casing 16 of the outer casing. The creative panel 14 is formed flat and is installed with a gap between the top surface 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 control unit 15 includes a memory element for storing a predetermined control program, and individually controls the circulation fan 5, the ventilation fan 11, the heating unit 7, and the rotary windshield 6 in accordance with an operation command input from the remote controller to make the bathroom dryer 91 performs a ventilation operation, a drying operation, and the like.

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 2a can be suppressed. The height of the bathroom dryer 91 can 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.

Further, the width and depth of the ventilation unit 91B are set to be equal to or less than the width and depth of the circulation unit 92A, and the ventilation unit 91B is disposed above the circulation unit 91A, and the bathroom ventilation system utilizes the circulation air passage 2a by the rotary windshield. The ventilation air passage 2b is connected to each other, and not only the ventilation air passage 2b having a sufficient opening area but also the bathroom dryer 91 can be miniaturized. Moreover, the bathroom dryer 91 is easy to assemble and disassemble the bathroom ceiling, and the installation property and the maintainability are excellent.

Next, the ventilation operation, the drying operation, the cool air operation, the air drying operation, and the heating 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 distal end of the rotary damper 6 is swung counterclockwise to a position in contact with the circulation orifice (bottom 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 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 91 is disposed passes through the circulation suction port 4 and flows in the circulation air passage 2a, is guided to the ventilation connection port 9 by the rotary windshield 6, and passes through the bathroom suction port 12a of the ventilation air passage 2b. It is inhaled by the ventilation chamber 12. Further, the air in the other chambers other than the bathroom is also taken in from the other chamber suction port 12b by the ventilation chamber 12, and the bathroom air and the other chamber air are taken in from the ventilation inlet 10 by the ventilation fan 11, and then the exhaust port 13 is exhausted. Therefore, the bathroom and other rooms are ventilated.

In the drying operation, as shown in Fig. 3, the front end of the rotary windshield 6 is not in contact with the partition plate 19 and the circulation orifice (base plate) 17, and is positioned between the partition plate 19 and the circulation orifice (base plate) 17. The position is close to the side of the partition 19 side. Therefore, air can flow from the ventilation connection port 9 to the ventilation path of the ventilation air passage 2b and the downstream side of the circulation air passage 2a where the heating unit 7 is disposed. At the same time, the circulation fan 5 and the ventilation fan 11 start to operate, and 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 outlet 8 into the bathroom, and partially passes through the ventilation connection port 9 and the bathroom suction port 12a. The rearward ventilation chamber 12 flows in, is mixed with the air taken in from the other chamber suction port 12b, is sucked by the ventilation fan 11, and is exhausted from the exhaust port 13 to the outside. In the dry operation, the bathroom or the clothes are dried by blowing a warm air to the bathroom, 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 not in contact with the partition plate 19 and the circulation orifice (base plate) 17, and is positioned between the partition plate 19 and the circulation orifice (base plate) 17. The position is close to the side of the partition 19 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 and the ventilation fan 11 start to operate, and unlike the drying operation, the heating unit 7 is not energized.

In the cool air operation, the bathroom air which 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 passes through the ventilation connection port 9 and the bathroom suction port 12a and is turned to the ventilation chamber 12 The inflow is mixed with the air taken in from the other chamber suction port 12b, sucked by the ventilation fan 11, and then exhausted from the exhaust port 13 to the outside. In the cool breeze, one can ventilate the air in the bathroom, and the heat can be drained from the bathroom.

In the air drying operation, as shown in Fig. 4, the front end of the rotary windshield 6 is not in contact with the partition plate 19 and the circulation orifice (base plate) 17, and is positioned from the partition plate 19 and the circulation orifice (bottom plate) 17. The intermediate position is near the side of the circulation orifice (bottom plate) 17. 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 and the ventilation fan 11 start 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 passes through the ventilation connection port 9 and the bathroom suction port 12a. The air is introduced into the ventilating chamber 12, mixed with the air taken in from the other chamber suction port 12b, sucked by the ventilating fan 11, and then exhausted from the exhaust port 13 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, and the room temperature is sent to the bathroom, and the bathroom is ventilated and dried. Clothing. 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 heating operation, as shown in Fig. 5, the rotary windshield 6 is rotated to a position in contact with the partition plate 19, and the ventilation connection port 9 is plugged, and the air can be only to the circulation air passage 2a continuous with the circulation air outlet 8. The downstream flows in. At the same time, the circulation fan 5 starts to operate, and the heating unit 7 is energized.

In the heating 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 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 the inside of the bathroom can be warmed.

Next, the multi-chamber ventilation function of the bathroom dryer 91 will be described with reference to Figs. 1 and 6 . As shown in Fig. 6, a plurality of (three) other chamber suction ports 12b are provided in the ventilation air passage 2b. The ventilation pipe from the other chamber is connected to each of the other chamber suction ports 12b, and when the ventilation fan 11 is operated, the ventilation of the other chamber can be performed. 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 ventilate the circulation air passage 2a in order to simultaneously operate the circulation fan 5 and the ventilation fan 11. The air passage 2b is supplied with a drying operation, 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 91 is stopped, as shown in Fig. 5, as long as the rotary damper 6 is placed at the position where the ventilation connection port 9 is closed, only the other chamber can be ventilated.
