[0042]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0043]
FIG. 1 is a perspective view showing the overall configuration of the bathroom dryer according to the embodiment, which is turned upside down to make the internal structure easy to see. An exhaust port 11 is formed on one side surface of the casing 10 constituting the main body, and an exhaust port 12 is formed on another side surface different from the exhaust port 11, thereby forming a plurality of exhaust ports having different exhaust directions. A blower fan 14 that is rotated by a motor 13 is provided inside the casing 10, and the wind from the blower fan 14 is controlled by a damper 15 so that the air flows into the exhaust port 11, the exhaust port 12, or the bathroom. The air is blown from the passage 16 through the heater 17 and the blowout grill 20 into the bathroom. The heater 17 generates heat when energized. The air blow control by the damper 15 will be described later.
[0044]
Further, a lid 18 is provided on the side of the casing 10 facing the bathroom, and a suction grill 19 serving as an inlet from the bathroom and an outlet grill 20 serving as an outlet are formed on the lid 18.
[0045]
Further, a control unit (not shown) is provided in the casing 10 and controls the motor 13, damper motor (not shown), heater 17 on / off, and the like. Further, a partition wall 72 is provided between the blower fan 14 and the air path.
[0046]
Next, the ventilation control by the damper 15 is demonstrated using FIG. 2 and FIG.
[0047]
FIG. 2 is a partial cross-sectional side view for explaining the operation of the bathroom dryer according to the present invention. 2A shows a drying mode, FIG. 2B shows a heating mode, FIG. 2C shows a ventilation mode, and FIG. 2D shows a drying mode in which the same effect as that shown in FIG.
[0048]
In each figure, the bathroom dryer is installed behind the ceiling of a bathroom (not shown), and the lower side of the figure is the bathroom. Of the exhaust port 11 and the exhaust port 12, the exhaust port 11 is used, and the unused exhaust port 12 is shielded by a shielding plate, and an exhaust duct 90 is attached to the exhaust port 11. An example will be described.
[0049]
Further, as shown in FIG. 3, the damper 15 includes a wall surface 31 having a curved surface and a pair of wall surfaces 32 and 33 formed at both ends thereof, and the rotation shaft 35 corresponding to the curved surface of the wall surface 32 and the wall surface 33. Is installed in the casing 10 so as to be rotated around the rotation shaft 35 and fixed at an arbitrary position by a damper motor (not shown) interlocked with the rotation shaft 35. Further, both ends of the wall surface 31 are extended, and roundness (R shape) 34 is formed at the extended end portion.
[0050]
In FIG. 2 (a), when the damper 15 is fixed at the first position rotated upward beyond the tip of the shielding plate 22, the air sucked from the bathroom through the suction grille 19 is sent by the blower fan 14. Air blown from the space formed between the upper outer wall and the shielding plate 23 to the exhaust duct 90 and the space between the shielding plate 24 and the shielding plate 25 through the heater 17 and the blow grill 20 from the space formed between the upper outer wall and the shielding plate 23. The air is blown in the air path indicated by the air path arrow 27 passing through.
[0051]
According to the air path indicated by the air path arrow 26, the air in the bathroom is exhausted to the outside from the exhaust duct 90, so that the bathroom is ventilated. On the other hand, according to the air path indicated by the air path arrow 27, the air blown from the blower fan 14 is blown into the bathroom via the blowout grill 20. At this time, since the warm air is blown into the bathroom when the heater 17 is turned on, drying in the bathroom is performed. When the heater 17 is turned off, air drying at normal temperature is performed.
[0052]
In addition, since the wind toward the upper outer wall from the blower fan 14 is blocked by the damper 15, it can be prevented from hitting the upper outer wall.
[0053]
As shown in FIG. 2B, when the damper 15 is fixed at a second position where the upper end of the damper 15 is aligned with the distal end of the shielding plate 22 and the lower end thereof is aligned with the distal end of the shielding plate 23, the wall surface 31 having a curved surface moves toward the exhaust duct 90. The air path to go is blocked. Accordingly, the air in the bathroom is taken into the bathroom dryer from the blow grill 20 by the blower fan 14 and circulated in the bathroom as indicated by the air path arrow 28. At this time, when the heater 17 is turned on, warm air is blown into the bathroom, so that the bathroom is heated. If only blowing is required, the heater 17 is turned off.
[0054]
As shown in FIG. 2C, when the damper 15 is rotated downward and fixed at a third position where the upper end of the damper 15 is aligned with the tip of the shielding plate 24 and the lower end thereof is aligned with the tip of the shielding plate 25, the damper 15 The air path toward the bathroom is closed, and all the air taken in from the bathroom by the blower fan 14 is directed to the exhaust duct 90 by the blower fan 14 as indicated by the airflow arrow 29. Therefore, the bathroom is ventilated.
[0055]
As shown in FIG. 2D, when the damper 15 is fixed at the fourth position of the damper 15 in a state where the blower outlet is partially opened, the air sucked from the bathroom via the suction grille 19 is The air is blown toward the exhaust duct 90 by the air path indicated by the air path arrow 29d and the air path indicated by the air path arrow 27d passing through the blower grill 20 from the space between the shielding plate 24 and the shielding plate 25 through the heater 17.
[0056]
According to the air path indicated by the air path arrow 29d, the air in the bathroom is exhausted to the outside from the exhaust port 11, so that the bathroom is ventilated. On the other hand, according to the air path indicated by the air path arrow 27 d, the air blown from the blower fan 14 is blown into the bathroom via the blowout grill 20. At this time, since the warm air is blown into the bathroom when the heater 17 is turned on, drying in the bathroom is performed. When the heater 17 is turned off, air drying at normal temperature is performed.
[0057]
Since the fourth position has the same air path configuration as the first position, the same effect as the first position can be obtained.
[0058]
In the above description, the case where the exhaust port 11 is used and the exhaust direction is performed as indicated by the air path arrows 26, 29, and 29d has been described. However, the exhaust duct is connected to the exhaust port 11 due to the structure of the ceiling and the mounting position. 90 may not be attached. In that case, the exhaust port 12 that opens in the direction in which the exhaust direction is shifted 90 degrees from the exhaust port 11 direction is used.
[0059]
In this case, the exhaust port 11 is shielded by a shielding plate, and an exhaust duct is attached to the exhaust port 12. At this time, the exhaust to the outdoors in FIGS. 2 (a), 2 (c), and 2 (d) is exhausted with the air blowing directions 26, 29, and 29d bent from the middle toward the exhaust port 12. Other operations are the same as described above in which the exhaust port 11 is used.
[0060]
In FIG. 2A, the tip of the damper 15 exists in the air path toward the exhaust port 11. Similarly, in FIGS. 2 (b) and 2 (d), the tip of the damper 15 exists in the air path toward the blow grill 20. When wind hits the tip of the damper 15, noise is generated. In order to prevent this, a roundness (R shape) 34 is formed at the tip of the damper 15 as shown in FIG. The air blown from the blower fan 14 by the roundness (R shape) 34 is smoothly blown at the tip portion of the damper 15 without peeling off the airflow, and the influence of Karman vortex can be reduced, so that noise is generated. Can be reduced.
[0061]
FIG. 4 is a perspective view showing details of the air path toward the heater 17 in the state of FIG. The air path in the direction of the exhaust duct 90 is shielded by the damper 15, and the air blown from the blower fan 14 is blown along the guide 41 in the heater direction. The heater 17 (not shown) is fixed to the main body by a block fixture 52.
[0062]
The guide 41 has a gentle slope so that the air from the blower fan 14 is smoothly blown toward the heater. This inclination reduces the resistance against wind generated in the heater portion. Moreover, the leak of wind is prevented by the wall surfaces 32 and 33 of the damper 15, and the leak of wind in the circulating flow is prevented.
[0063]
FIG. 5A is a perspective view showing the overall configuration of the heater 17. As the heater 17, one or a plurality of heater blocks 53 shown in FIG. 5B (four pieces in FIG. 5A) are prepared, and the heaters are provided in the holes 511 of the pair of support members 51 shown in FIG. The protrusions 531 and 532 on both sides of the block 53 are fitted and fixed, and fixed to the block fixture 52 shown in FIG. The heater 17 incorporating the heater block 53 fixes the block fixture 52 to the casing 10 as shown in FIG. A protective frame 54 shown in FIG. 5E is fitted on the front surface (bathroom side) of the heater 17 to prevent direct contact with the heater 17 during work.
[0064]
The heater block 53 is increased or decreased according to the heater capacity required for the bathroom dryer, and the number is determined at the time of assembly. For this reason, the size of the block fixture 52 is formed to be large enough to accommodate the number of heater blocks 53 necessary for the heating capacity assumed in advance. For example, if the heating capacity of one heater block 53 is 2 tatami mats, a bathroom with a size of up to 10 tatami mats can be provided as long as the heater block 53 can be accommodated as the block fixture 52. Since it can respond to heating, if the actual bathroom is 6 tatami mats, three heater blocks 53 may be attached to the block fixture 52.
[0065]
In this case, a heater shielding plate (not shown) is provided in a portion of the block fixture 52 where the heater block 53 is not incorporated, so that air does not pass through portions other than the heater. The end portion (edge portion) of the heater shielding plate forms a round shape (R shape) similarly to the round shape provided at the tip of the damper 15, and the airflow is smoothly blown without peeling, reducing the influence of Karman vortex. Therefore, the generated noise is reduced.
[0066]
If a hot water coil is provided instead of the heater 17, hot water heating can be performed.
[0067]
Thereby, the manufacturer can freely select whether the heating heat source is a heater system or a hot water coil system according to the request of the customer. In this case, a heat source space is secured so that both the heater 17 and the hot water coil can be installed.
[0068]
FIG. 6 is an inner view of the blow grill 20. The blow-out grill 20 is fitted into the lid 18 in FIG.
[0069]
The blowout louver 65 having a plurality of inclined grids is a part that controls the direction of the blown wind, and is configured not to swing like an air conditioner. For this reason, hot air is blown out from the blow-out grill 20 in the heating mode or the drying mode, but the contractor may want to change the air direction depending on the installation location of the bathroom dryer.
[0070]
In actual operation, the user often wants to change the wind direction. Therefore, in the present invention, the blowing grill 20 is square, and the blowing grill fixtures 61, 62, 63, 64 are provided on each of the four sides, and the blowing grill is provided for the two mounting portions 91 a, 91 b provided on the lid body 18. The attachments 61, 62, 63, and 64 are attached using two diagonal positions. Therefore, the direction of the blowout louver 65 is shifted by 90 degrees between the case where the blower grille is attached with the blowout grill attachments 61 and 62 and the case where the blowout grille attachments 63 and 64 are attached. Can be controlled.
[0071]
Further, if the blow grill grille fittings 61, 62, 63, 64 are provided with convex portions and fitted into the concave portions (not shown) of the fitting portions 91a, 91b from the lower side (bathroom side), the blow grill 20 is moved downward. Since it can be removed by pulling it in and can be fitted by pushing it upward, the work can be easily performed from below.
[0072]
In addition, if a wind direction mark is provided on the surface of the blow grill 20, it is possible to more easily determine the wind direction during the mounting operation.
[0073]
FIG. 7 is a cross-sectional view when the lid 18 is attached to the casing 10 in FIG. On the lid 18 side of the casing 10, the blower fan 14 side and the air passage side are separated by a partition wall 72. The lid 18 is separated from each other by a partition wall 71 formed between the suction grille 19 and the blowout grill 20.
[0074]
When the lid body 18 is attached to the casing 10, the partition wall 72 of the casing 10 and the partition wall 71 of the lid body 18 are connected, and the blower fan 14 side and the air passage side are separated within the casing 10 by the partition walls 71 and 72. .
[0075]
Accordingly, it is possible to prevent a so-called wind short circuit in which the air on the air passage side directly flows into or sucks into the air blowing fan inside the bathroom dryer.
[0076]
FIG. 8 is an external view of the suction grill 19. The suction grille 19 is fitted into the lid 18 in FIG.
[0077]
A filter that removes dust and the like in the air is attached to the suction grill 19. Since this filter needs to be periodically cleaned and replaced, it is preferable that the suction grille 19 is easily removable.
[0078]
Therefore, as shown in FIG. 8, a spring-like protrusion 83 is provided on one side of the suction grill 19, and a suction grill fixture 82 for the finger hook 81 and the lid 18 is provided on the opposite side.
[0079]
In order to remove the suction grille 19 with the bathroom dryer installed on the ceiling, if the finger hooking portion 81 is put on the finger 81 from below and pulled lightly while pulling downward, the suction grille fixing tool 82 is detached and the suction grille 19 is removed. The projection part 83 is removed from the lid 18 with the axis as the axis.
[0080]
Thereafter, the suction grille 19 can be completely removed from the lid 18 by removing the protruding portion 83 side. When the suction grille 19 is removed from the bathroom dryer, the filter is washed and replaced, mounted on the suction grille 19, the projection 83 side is fitted and pushed upward, and the suction grille fixing tool 82 causes the suction grille 19 to be attached to the bathroom. Fixing to the lid 18 of the dryer ends the installation.
[0081]
As described above, since the removal and attachment work of the suction grille 19 for cleaning and replacement of the filter can be performed from below, the workability is remarkably improved.
[0082]
Although the present invention has been described in detail with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.
[0083]
