Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a bathroom ventilation/drying device that supplies hot air into a bathroom to dry laundry, etc.

[Background technology]

When hot air is circulated in a bathroom to dry laundry, etc., moisture evaporating from the laundry increases the humidity in the bathroom, resulting in a decrease in drying efficiency. In order to solve this problem, for example,
As shown in Japanese Patent No. 29529, it has been proposed to switch dampers provided in the air passage to circulate warm air in the bathroom or to exhaust humid air from the bathroom to the outside of the bathroom.

However, with the above items, the damper can be operated to ventilate the bathroom before drying starts and after drying is completed, but during drying, hot air is circulated within the bathroom, resulting in high humidity inside the bathroom. A problem arose. In addition, as shown in Publication No. 57-39712,
There have also been proposals that operate two blowers at the same time to perform circulation and ventilation at the same time.
When drying laundry with this method, there was a problem in that the amount of air exhausted outside due to ventilation was too large, making it impossible to dry laundry efficiently.

[Purpose of invention]

This invention was created in view of the above problems, and its purpose is to circulate warm air inside the bathroom during drying, and forcefully discharge a portion of the humid air in the bathroom to the outside in an appropriate amount. It is an object of the present invention to provide a bathroom dryer which prevents an increase in humidity in a bathroom and improves drying efficiency by providing a means for increasing the drying efficiency.

[Disclosure of invention]

The bathroom ventilation drying device of the present invention partitions a first chamber 21 and a second chamber 22 through a partition wall 13, and
A first blower 11 is provided in the chamber 21, and a second blower 12 is provided in the second chamber 22.
an external exhaust port 9 is provided in the second chamber 21, and a ventilation hole 14 is opened in the partition wall 13 to form a first chamber.
A ventilation control plate 19 is installed in the ventilation hole 14 of the partition wall 13 in the ventilation direction to connect the chamber 21 and the second chamber 22 and to prevent the air from the first blower 11 from flowing directly into the ventilation hole 14. The above object was achieved by this arrangement.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Reference numeral 1 denotes a dryer attached to the ceiling of a unit type bathroom 2. Hanging bolts 4 are provided on a concrete ceiling wall 3 above the bathroom 2, and the dryer is hung from the hanging bolts 4 via hanging fittings 5. A box-shaped main body case 6 with an open bottom surface of the dryer 1 is connected to a first chamber 21 by a partition wall 13.
and a second chamber 22, and a first chamber 21.
A grill plate 25 is fitted into the lower opening of the
A suction port 7 and a discharge port 8 that open into the bathroom 2 are formed on the grill plate 25, and an external discharge port 9 that opens to the outside of the bathroom 2 is formed on the side wall of the main body case 6 on the second chamber 22 side. The external exhaust port 9 is connected to an exhaust duct 10. In the first chamber 21, a first blower 11 having a fan rotated by a motor and corresponding to the suction port 7 and the discharge port 8, respectively, and a heat pipe 15 formed in a zigzag shape are housed. Further, the second chamber 22 houses a second blower 12 having a fan rotated by a motor. The heat pipe 15 is a heating boiler 1 that supplies hot water into a bathtub as shown in FIG.
7 or connected to a heat source C placed outside the bathroom 2 via a water pipe 18, and hot water is passed through the heat pipe 15. Partition wall 13 separating first chamber 21 and second chamber 22
A ventilation hole 14 is opened, and the first chamber 21 and the second chamber 22 are communicated with each other through the ventilation hole 14. Moreover, the ventilation hole 14 has a ventilation direction by the first blower 11. The ventilation control board 19 is perpendicular to the
is provided by cutting and raising the first chamber 2.
The amount of ventilation from the first chamber to the second chamber 22 is limited to an appropriate amount.

Therefore, during drying operation, hot water flows into the heat pipe 15 of the hot water coil, and the first blower 11 and the second blower 12 rotate slightly. The air sent by the first blower 11 is sent into the first chamber 21, is blocked by the partition wall 13, and most of it passes through the heat pipe 15 section, becoming warm air, and is then sent from the outlet 8 of the grill plate 25 to the bathroom. Sent within 2. At this time, the first chamber 2
A part of the air inside the chamber 1 flows into the second chamber 22 through the ventilation hole 14 of the partition wall 13 and is discharged to the outside by the second blower 12. The circulation of warm air dries laundry etc. in the bathroom 2, and a portion of the hot air containing moisture passes through the ventilation path 14 and is sent to the second blower 1.
2 to the outside to prevent a drop in drying efficiency due to an excessive rise in humidity, and also to prevent the drying efficiency from decreasing due to excessive humidity rise.
9 limits the amount of exhaust air from the ventilation hole 14 to prevent the air volume from decreasing. Further, during ventilation operation, only the second blower 12 rotates, and the air inside the bathroom 2 is sucked in through the ventilation holes 14 of the partition wall 13 through the suction port 7 and the discharge port 8 of the grill plate 25, and is discharged to the outside. Here, the second blower 12 can be selected between strong and weak rotation, and by rotating it weakly during drying operation and rotating strongly or weakly during ventilation operation, the exhaust volume with the best drying efficiency can be set during ventilation operation. At times, it is now possible to emit the amount of exhaust according to the required amount.

Next, to explain the circuit, the circuit diagram is as shown in Fig. 3, and the configuration of control switch B is equipped with a power switch S4, a timer T, and a strength changeover switch S5. S4 is composed of three circuit contacts.
When timer T is turned on, switches S4 and S5 turn on.
Since it is on the NC contact side, the second blower 12 can be operated at high power, and at this time, the thermal valve Hv that supplies hot water to the heat pipe 15 is not energized and only air is blown, allowing ventilation in the bathroom 2 to be operated at high power. I will do it.
Furthermore, when the switch S5 is switched to the NO side from this state, the second blower 12 can perform ventilation in a weak operation. Furthermore, when switch S4 is connected to the NO side, heat source device C is turned on and thermal valve Hv is turned on.
is energized, the valve opens, hot water flows through the heat pipe 15 and is heated, the first blower 11 and the second blower 12 are both operated, and hot air is circulated within the bathroom 2. At this time, the second blower 12 is operated in a weak manner, regardless of the switching of the switch S5. In either case, a timer T is activated and the operation is stopped after a certain period of time has passed after the operation.

[Effect of idea]

Since the present invention is constructed as described above, even during drying, a part of the air containing moisture can be exhausted to the outside through the ventilation duct, thereby preventing the humidity in the bathroom from becoming excessively high and reducing the drying efficiency. Moreover, the ventilation control board restricts the amount of air escaping from the ventilation holes, which prevents a decrease in the amount of air circulating in the bathroom, and the simple structure allows the appropriate amount of air to be exhausted during drying operation. It also has the advantage of being able to circulate hot air, and to simultaneously draw in and exhaust air from both the suction port and the discharge port in accordance with the conditions during ventilation operation.
