Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sanitary ventilation / drying system for circulating or exhausting air in a sanitary room such as a bathroom, a toilet and a washroom.

[0002]

2. Description of the Related Art A conventional sanitary ventilation / drying system of this type is known, for example, as disclosed in Japanese Utility Model Publication No. 3-6312 shown in FIG.

In such a sanitary ventilation / drying system, the bathroom drying unit 2 is arranged on the ceiling portion 1a of the bathroom unit 1. The bathroom drying unit 2 includes a circulation blower 3 that circulates or exhausts the air in the bathroom 1b.
And a heat source 4 are provided.

A toilet side suction port 5 is provided in the toilet room 1c. Further, in order to reduce the space and weight and to simplify the installation process, a ventilation unit 6 is provided above the toilet room 1c separately from the bathroom drying unit 2, and the exhaust air of the bathroom drying unit 2 is exhausted. It is connected to the side opening 2a by a connection duct 7.

The fan 6a of the ventilation unit 6
Is driven to rotate, the humid air in the bathroom 1b is exhausted to the outside through the main duct 8, and the air in the toilet room 1c is also ventilated at the same time.

[0006]

However, in such a conventional sanitary ventilation / drying system, since the bathroom drying unit 2 and the ventilation unit 6 are separately arranged, the switch of the circulation blower 3 is changed. When it is inserted and driven, the fan 6a of the ventilation unit 6 must be driven at the same time.

For this reason, the circulation blower 3 and the fan 6a are double driven, and the efficiency is not good when only the ventilation in the toilet room 1c is desired.

Generally, in a sanitary unit house, a wash room (not shown) is provided adjacent to the bathroom 1b and the toilet room 1c. In recent years, high-humidity generators such as clothes dryers and wash basins are often placed in the washroom. In addition, high-humidity air flows in from the bathroom 1b through the connection duct 7 and causes dew condensation or mold in the toilet room 1c and these washrooms.

Therefore, by the ventilation unit 6,
It is desired to collect the air in the washroom and perform intensive ventilation.

However, if the toilet unit 1c and the washroom are intensively ventilated by using the ventilation unit 6, the ventilation flow rate decreases by the amount of the air flow sucked from the bathroom 1b. Is not good. Therefore, there is a problem that it is difficult to simultaneously ventilate the toilet room 1c and the washroom using the same ventilation unit 6.

Therefore, an object of the present invention is to provide a sanitary ventilation / drying system capable of efficiently dehumidifying.

[0012]

In order to solve the above-mentioned problems, according to the first aspect of the present invention, the circulation device is arranged on the ceiling part of the bathroom to circulate or exhaust the air in the bathroom. A bathroom drying unit equipped with a blower and a heat source,

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described below with reference to the drawings.

1 to 6 show a first embodiment of the present invention. It should be noted that the same or equivalent parts as in the conventional case will be described with the same reference numerals.

First, the structure will be described. In the sanitary ventilation / drying system of this embodiment, as shown in FIG. 1, the bathroom drying unit 2 is disposed on the ceiling portion 1a of the bathroom unit 1. As shown in FIG. 3 , the bathroom drying unit 2 is provided with a circulation blower 3 and a heat source 4 that circulate or exhaust air in the bathroom 1b. A makeup panel 2e is provided on the bathroom 1 side of the bathroom drying unit 2. The decorative panel 2e is formed with a suction port 2b for sucking air in the bathroom 1 and a blowout port 2c for blowing air into the bathroom 1. Filters 2d, 2d for catching dust are provided at the suction port 2b and the blowout port 2c, respectively.

On the side surface of the bathroom drying unit 2, an exhaust side opening 2a for discharging high humidity air sent from the circulation blower 3 is formed.

A toilet-side suction port 5 is provided in the toilet room 1c adjacent to the bathroom 1b. A washroom side suction port 9 is provided in the washroom 1d adjacent to the bathroom 1b and the toilet room 1c. A collective ventilation unit 10 is provided above the washroom 1d separately from the bathroom drying unit 2 in order to reduce the space and weight and to simplify the mounting process.

The collective ventilation unit 10 is connected to the exhaust side opening 2a of the bathroom drying unit 2 by the connection duct 7 for sending the exhaust gas sent from the circulation blower 3 into the collective ventilation unit 10. .

The collective ventilation unit 10 is also connected to the toilet suction port 5 and the sink suction port 9 by the toilet connection duct 11 and the wash connection duct 12.

The collective ventilation unit 10 includes
The air in each room 1c, 1d that is sucked from the toilet side suction port 5 and the sink side suction port 9 and sent through the ducts 11, 12 is taken in, and the air is exhausted to the outside. An exhaust blower 6a is provided through the main duct 8.

An opening / closing damper unit 13 as shown in FIGS. 4 and 5 is arranged at the exhaust side opening 2a of the bathroom drying unit 2. The opening / closing damper unit 13 is provided with an opening / closing damper 14 as an opening / closing valve that blocks the flow of air in the connection duct 7. The opening / closing damper 14 is rotatably supported by a rotating shaft 14a, and is eccentrically rocked by being provided in a groove 14b formed in a side portion at an eccentric position with respect to the rotating shaft 15a of the motor 15. When the eccentric shaft 16 is inserted, the eccentric shaft 16 is rotated in the direction shown by the arrow in FIG.

A controller 17 as a control unit is electrically connected to the bathroom drying unit 2, the collective ventilation unit 10 and the motor 15. This controller 1
In FIG. 7, as shown in FIG. 6, the exhaust air blower 6a is driven in association with the driving of the circulation blower 3 by selecting the bathroom drying mode and the clothes drying mode.

A humidity sensor 18 is connected to the controller 17. The humidity sensor 18 is configured to detect the humidity atmosphere in the washroom 1d and drive the exhaust blower 6a according to the detected condition.

The controller 17 is connected to a mode selection switch 19 provided on the wall of the washroom 1d for switching between ventilation modes, and is also provided on the wall of the toilet room 1c. A toilet ventilation switch 20 for selecting the toilet ventilation mode is connected to each.

In the controller 17, the toilet ventilation switch 20 selects the toilet ventilation mode, and the mode selector switch 19 manually selects the washroom ventilation mode. When the circulation blower 3 is not driven, the opening / closing damper 14 is set to be closed.

Further, in the controller 17, when the cool air mode and the bathroom heating mode are selected by the mode selector switch 19, the opening / closing damper 14 is set to be closed.

Further, the controller 17 is set so as to close the opening / closing damper 14 at high humidity depending on the detection state of the humidity sensor 18.

Further, in the first embodiment, the ventilation switch 20 and the like are arranged so that the switch of the illumination of each room is interlocked.

Next, the operation of the first embodiment will be described.

In the controller 17, when the bathroom drying mode and the clothes drying mode are selected by the mode selection switch 19, the exhaust blower 6a is driven in conjunction with the driving of the circulation blower 3. Therefore, the high-humidity air discharged from the bathroom 1b by driving the circulation blower 3 is exhausted to the outside by the exhaust blower 6a through the connection duct 7.

Therefore, the operator only has to perform the selection operation by the mode selection switch in the bathroom drying mode and the clothes drying mode for driving the circulation blower 3, so that the operability is good.

Further, the circulation blower 3 suppresses an increase in space and weight, and even if a relatively small one is used, it is further pressurized by the exhaust blower 6a and exhausted, so that the amount of blown air is insufficient. , The drying function of the bathroom drying unit 2 can be fully brought out.

Then, the humidity sensor 18 is installed in the washroom 1d.
When it is detected that the humidity atmosphere inside is high humidity and the exhaust blower 6a is driven independently, the opening / closing damper 14
However, it is closed by rotating around the shaft 14a. Therefore, the flow of air flowing from the connection duct 7 into the collective ventilation unit 10 is blocked.

In addition, the operator manually selects the toilet ventilation mode with the toilet ventilation switch 20 or selects the washroom ventilation mode with the mode changeover switch 19, so that the exhaust blower 6a can be operated. When the switch is turned on, ventilation in the toilet room 1c or the washroom 1d is performed, so that the exhaust blower 6a is independently driven.

At this time, the opening / closing damper 14 is closed, and the flow of air from the connection duct 7 into the collective ventilation unit 10 is blocked.

Therefore, even when the collective ventilation unit 14 is used to intensively ventilate the toilet room 1c and the washroom 1d, a sufficient ventilation flow rate can be ensured and the ventilation efficiency is good.

Therefore, even if a high humidity generating device such as a clothes dryer or a hair wash basin is placed in the washroom 1d, a low humidity atmosphere can be maintained. Also, the connection duct 7
The high-humidity air that has entered before closing the opening / closing damper 14 and the high-humidity air that has entered by opening and closing the door of the bathroom 1b can be exhausted, and a low-humidity atmosphere can always be maintained. The risk of condensation and condensation is reduced.

For ventilation of the washroom 1d having high humidity, the same collective ventilation unit 14 is used for the toilet room 1c.
Since it can be performed together, it is not necessary to separately install a ventilation fan or the like in the washroom 1d, and space efficiency can be improved.

Moreover, the air containing odors and the like generated in the toilet room 1c and the washroom 1d is transmitted through the connection duct 7,
Since there is no backflow to the bathroom 1b, there is no risk of giving a bather discomfort.

Further, since the exhaust blower 6a can be driven independently by manually selecting the toilet ventilation mode or the washroom ventilation mode, the circulation blower 3 and the exhaust blower 6a are duplicated. It is possible to suppress the amount of electricity consumed as compared with the one that is driven.

Further, in this embodiment, the opening / closing damper 14 is closed even when the cool air or bathroom heating mode is selected, so that high humidity air from the bathroom 1b is supplied to the other rooms 1c and 1d.
Since the bathroom 1b can be sealed substantially without leaking to the bathroom, the bathroom heating efficiency is good.

FIG. 7 shows a sanitary ventilation / drying system according to the second embodiment of the present invention. In addition, the same or equivalent portions as those in the first embodiment will be described with the same reference numerals.

In the open / close butterfly damper 21 serving as the open / close valve of the sanitary ventilation / drying system of the second embodiment, the rotary shaft 14a for rotatably supporting the shaft is formed in the substantially central portion of the open / close butterfly damper 21. , The motor 1
The rotary shaft 15a of No. 5 is connected to the rotary shaft 21a.

In the open / close butterfly damper 21 of the second embodiment having such a configuration, the open / close butterfly damper 21 is driven in the direction indicated by the arrow in FIG.
The connection duct 7 is rotated so as to prevent the flow of air in the connection duct 7.

The other structure and operation are substantially the same as those of the first embodiment, and therefore the description thereof will be omitted.

Although the embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and the present invention can be applied even if there is a design change or the like without departing from the scope of the invention. include.

For example, in each of the above embodiments, the on-off valve 14,
21 is provided at the exhaust side opening 2a of the bathroom drying unit 2, but not limited to this, for example, in the middle of the connection duct 7 or near the entrance opening of the collective ventilation unit 10.
It may be provided at any place as long as it can block the flow of air in the connection duct 7.
