Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washroom ventilation system for taking in outside air (cool air) into a washroom such as a house.

[0002]

2. Description of the Related Art Conventionally, unlike a kitchen, a living room, etc., a washroom in a building such as a general house is rarely ventilated by providing a ventilation fan, an air conditioner, etc. For example,
Japanese Patent Laid-Open No. 533 describes an underfloor ventilation device which is provided with a ventilation fan that connects a room and an underfloor to each other and allows cold air under the floor to flow into the room.

[0003]

However, the above-mentioned underfloor ventilation device described in Japanese Utility Model Laid-Open No. 62-189533 relates to a general room, and especially in summer when humidity is high in Japan, a bath is used in a washroom. It is difficult to get a refreshing feeling after rising.

The present invention has been made by paying attention to the above-mentioned problems, and the purpose thereof is to positively introduce outside air (cold air) under the floor into the washroom by a ventilation fan, or The exhaust ventilation provides a washroom ventilation system that can provide a ventilation effect and a refreshing feeling.

[0005]

In the washroom ventilation system according to the present invention as set forth in claim 1, a ventilation fan having an intake port communicating with the underfloor is provided in the washroom, and outside air (cold air) under the floor is washed in the washroom. The feature is that it was made to be supplied to. Further, in the washroom ventilation system of the present invention according to claim 2, an opening is provided in the washroom to face the outside, and an exhaust fan for exhaust is provided in this opening to simultaneously exhaust the washroom. It is characterized by being performed.

[0006]

In the washroom ventilation system according to the first aspect of the present invention, a blower fan having an intake port communicating with the underfloor is provided in the washroom so that outside air (cold air) under the floor is supplied to the washroom. According to the above, in the washroom ventilation system of the present invention according to claim 2, the washroom is provided with an opening facing the outdoors, and the opening is provided with a ventilation fan for exhaust. Since the washroom is exhausted at the same time, the outside air under the floor (cold air) enters the washroom.
By actively taking in or exhausting the air, it is possible to obtain a ventilation effect and a refreshing feeling in the washroom.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing an example of a washroom ventilation system of the present invention according to claim 1. In FIG. 1, 1 is a washroom and 2 is the floor of the washroom. Below this floor 2 is below the floor 3. Reference numeral 4 denotes an outer wall that separates the washroom from the outdoors. A blower fan 5 is installed along the wall of the outer wall 4 on the washroom 1 side. The blower fan 5 is provided with an intake port 5a having a filter sandwiched on the bottom surface. The floor 2 has an opening 2 corresponding to the shape and area of the intake port 5a.
a is provided, and the intake port 5a is installed in the opening 2a and communicates with the underfloor 3. Further, the blower fan 5 is provided with an air passage 5b. Above the air passage 5b, a cool breeze is directly applied to the body at a position approximately in the middle of the body with a person standing. Fan 5c to hit
The outlet 5d provided with is provided so as to be slightly upward.

The blower fan 5 is switched on,
When the fan 5b starts rotating, a negative pressure is generated on the intake port 5a side, and as shown by an arrow in FIG.
Is taken in through the intake port 5a, passes through the passage 5b in the fan 5 and is blown out into the washroom 1 through the blowout port 5d so that it can be directly applied to the body, and the washroom 1 is filled with outside air (cold air). Will be

FIG. 2 is a perspective view showing an example of the washroom ventilation system according to the present invention. In FIG.
Reference numeral 10 denotes a washroom. On the floor 11 of the washroom 10, the blower fan 12 has an outer wall 13 as in the first embodiment.
It is installed in the opening 11a on the floor 11 along the inner surface of the floor. The bottom surface of the blower fan 12 is provided with an intake port 5a in which a filter is sandwiched, and the intake port 5a communicates with an underfloor (not shown) through an opening 11a. Reference numeral 12b is an air outlet provided to be opened in the washroom 10, and the air outlet 12b is directed toward the interior of the washroom 10 at a position approximately in the middle of the body when a person stands.
It is provided so that the cool breeze hits the body directly.

Above the wall surface 15 in front of the washroom 10,
A ventilation fan 14 for exhaust air is provided at the opening provided to the outside.
Is provided so as to communicate with the outside, and the air in the washroom 10 is exhausted to the outside.

When the blower fan 12 is switched on and the fan starts rotating, a negative pressure is generated on the side of the intake port 12a, the outside air (cool air) under the floor is sucked, and the blowout port 12b of the blower fan 12 is introduced. The wash room 1 is filled with outside air (cool air) by blowing air into the wash room 10. On the other hand, the ventilation fan 14
, Or by operating in conjunction with each other, the air accumulated in the washroom 10 is sucked toward the ventilation fan 14 and exhausted to the outside from the ventilation fan 14 as shown by the arrow in FIG. Due to the synergistic effect with the supply of air by the operation of the blower fan 12, more effective ventilation is performed.

In the above embodiment, the operation of the fan by a person is carried out, but it is also possible to perform an automatic operation by installing a sensor such as an infrared ray which detects the entrance and exit of a person in the washroom.

[0013]

In the washroom ventilation system according to the first aspect of the present invention, a blower fan having an intake port communicating with the underfloor is provided in the washroom, and outside air (cold air) under the floor is supplied to the washroom. By doing so, in the washroom ventilation system of the present invention according to claim 2, an opening is provided in the washroom facing the outdoors, and an exhaust ventilation fan is provided in this opening. Since the washroom is exhausted at the same time, the ventilation effect and the refreshing feeling of the washroom can be obtained by actively taking in or evacuating the outside air (cold air) under the floor into the washroom. it can. Therefore, it is suitable as a washroom ventilation system for a house or the like.
