BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underfloor ventilation system for a building, such as a general house, which performs ventilation and dehumidification under the floor.

[0002]

2. Description of the Related Art Wooden houses have been favored in Japan since ancient times in accordance with a humid climate. However, in recent years, houses using fire-resistant and earthquake-resistant mortar and new building materials have become popular. Such a house is solid, has a high degree of sealing, and is excellent in fire and earthquake resistance, but has a drawback in that ventilation of the entire house, particularly, ventilation of a portion under the floor is not performed smoothly. If the underfloor ventilation is not sufficient, moisture accumulates inside, which tends to cause pests such as mites and fungi. It also causes asthma and allergies in children. In order to solve this problem, conventionally, a ventilation device exclusively used under the floor has been installed.

[0003]

[Problems to be solved by the invention] However, the above-mentioned conventional method has the following problems. That is,
Installing a new underfloor ventilator is expensive. In addition, since the ventilator is operated continuously for a long period of time, maintenance costs such as electricity costs are increased.

[0004] By the way, in Japan, the diffusion rate of air conditioners in general households exceeds 90%. However, the present inventor thought that this outdoor unit of the air conditioner could be used for under-floor ventilation and completed the present invention. It has been reached.

[0005]

[0008]

During operation of the air conditioner, the fan of the outdoor unit rotates to discharge the air under the floor of the building to the outside through the ventilation port, so that the ventilation under the floor is performed. This allows
Moisture does not accumulate under the floor, so that the occurrence of pests such as mites and fungi can be suppressed, and the antiseptic effect of building materials can be expected.

[0009] The outdoor unit is provided outside the ventilation port .
It is easy to install, easy to maintain, and convenient.

The outdoor unit is disposed inside the duct.
Therefore, it is less likely to be exposed to the weather and rust and damage can be prevented.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in more detail with reference to the embodiments shown in the drawings. FIG. 1 is an explanatory view showing an embodiment of the underfloor ventilation device according to the present invention. A reference numeral A1 is an underfloor ventilation device that ventilates under the floor of a building. The underfloor ventilation device A1 is provided with an arbitrary ventilation port 30 among a required number of ventilation ports provided on the cloth foundation 3 of the house H. In addition, the cloth foundation 3 and the floor 40
The portion surrounded by is the lower floor 4.

A duct 2 made of FRP is provided outside the ventilation port 30. Opening 2 inside duct 2
1 corresponds to the ventilation port 30. Reference numeral 22 is a joint member, by filling the gaps of the periphery of the opening 2 1, the air inside the underfloor portion 4 is so drawn efficiently.

An outdoor unit 1 for an air conditioner is disposed inside the duct 2. The outdoor unit 1 is installed with its direction set so that air can be discharged from the ventilation port 30 during operation. The outdoor unit 1 has a box-shaped case 10 formed to be able to ventilate back and forth. Inside the case 10, a fan 11 and a heat exchange unit 12 are provided. The outdoor unit 1 is installed close to the opening 23 outside the duct 2, and the outer surface of the case 10 is connected to the peripheral edge of the opening 23 by a joint material 24 without any gap.

(Operation) The operation of this embodiment will be described with reference to FIG. First, air conditioners have recently been used almost all year since air conditioners are of the dual-purpose type, which can cool and heat air, and can effectively perform dehumidification and the like. During the operation of the air conditioner, the fan 11 of the outdoor unit 1 rotates to draw air in the lower floor 4 of the house H through the ventilation port 30 and discharge the air to the outside of the duct 2. At the same time, new air is drawn into the lower floor 4 from another ventilation port (not shown), and the lower floor 4 is ventilated.

As a result, moisture does not accumulate in the lower part of the floor 4,
In addition to suppressing the occurrence of pests such as mites and fungi, the antiseptic effect of building materials can be expected. Further, since the outdoor unit 1 is disposed in the duct 2, the outdoor unit 1 is less likely to be exposed to wind and rain, and rust and damage can be prevented.

Furthermore, since the ventilation of the lower floor 4 is performed by effectively utilizing the suction action of the fan 11 which has been conventionally used only for the heat exchange of the heat exchange section 12, a ventilation device for the lower floor is separately provided. Unlike the case of providing, there is no new maintenance cost and no waste. In addition, since the air in the lower floor 4 having a lower temperature than the outside air temperature can be generally used for heat exchange of the outdoor unit 1, the efficiency of heat exchange is improved, which is preferable from the viewpoint of energy saving. It should be noted that the present invention is not limited to the illustrated embodiment, and various modifications are possible within the scope of the claims of the present invention.

[0017]

[Effects of the Invention] The present invention has the above configuration and has the following effects. (A) During the operation of the air conditioner, the fan of the outdoor unit rotates, and the air under the floor of the building is discharged to the outside through the ventilation port, whereby the air under the floor can be ventilated. As a result, moisture does not accumulate under the floor, the occurrence of pests such as mites and fungi can be suppressed, and the antiseptic effect of building materials can be expected.

(B) Since the lower part of the floor is ventilated by effectively utilizing the suction action of the outdoor unit of the air conditioner, which has been used only for the heat exchange of the heat exchange part, a separate underfloor ventilation device is provided. Unlike the case, there is no new maintenance cost and no waste. Further, since the air in the lower part of the floor, which is lower in temperature than the outside air temperature, can be usually used for heat exchange of the outdoor unit, the efficiency of heat exchange is improved, which is preferable from the viewpoint of resource saving and energy saving.

[0019] Since the (c) the outdoor unit is provided on the outer side of the ventilation opening, installation easily, it is convenient it can be easily maintained.

(D) The outdoor unit is disposed inside the duct.
Therefore, it is less likely to be exposed to the elements, preventing rust and damage.
Can be stopped.
