In order to solve the above problems, according to the present invention, a chamber installed at a predetermined location of a house is constructed so that air is supplied from an air supply box by a fan and the air is sucked into an exhaust box. By forming an independent air supply / exhaust system between the fan and multiple rooms in the house that require ventilation, the chamber fan can be connected to each room regardless of the distance between the chamber fan installation location and the room. By equalizing the ventilation volume for air supply to each room and adjusting the ventilation volume for each room as needed, by including negative ions in the ventilation air supplied to each room The room is provided with a negative ionization comfortable living environment, that is, the invention according to claim 1 is provided with an air supply box, an exhaust box, and an air supply / exhaust. Chamber fan having the above fan, and a large number of air supply ducts and exhaust ducts dedicated to each room, which are arranged so as to directly connect the air supply port and the air exhaust port of each room with a large number of duct holes arranged in the chamber fan. A centralized ventilation system for a house, comprising: an air supply box of the chamber fan or a negative ion generating means arranged in a duct hole thereof; and an air volume adjusting means arranged in each of the plurality of duct holes. It was done.

In addition to the above, the invention according to claim 2 is,
For example, dehumidification in the rainy season and summer, air conditioning for heating and cooling in the summer and winter, deodorization of air supply, deodorization, dust removal, etc. are performed in the chamber fan, and in addition to the above-mentioned negative ionization, each room in which air is supplied from the chamber fan In order to make the living environment comfortable at the same time as a high-performance centralized ventilation device, the ventilation device is provided with a dehumidifying function externally or internally installed in the chamber fan, and a heat exchanging means. A single or a plurality of highly functionalized means such as a replacement function, a deodorizing function by a deodorizing means, a slight aroma adding function by a perfuming means, and / or a dust removing function by a dust removing means are additionally provided. The centralized ventilation device for a house according to Item 1.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in more detail below with reference to the examples of the drawings. A is a central ventilation device, and the central ventilation device A is an air supply box 3, an exhaust box 2 and an air supply / exhaust device. A chamber fan 1 having a fan 5; a large number of duct holes 6 opened in the chamber fan 1; and a large number of exclusive units for each room arranged so as to directly connect the air supply port 9 and the exhaust port 10 of each room individually. Air supply duct 7 and exhaust duct 8 and air supply box 3 of the chamber fan 1
Or, the negative ion generating means arranged in the duct hole 6 and the air volume adjusting means 1 arranged in each of the plurality of duct holes 6
2 is provided.

In the present embodiment, the chamber fan 1 is configured such that, for example, by partitioning the middle of the chamber 2 with an intermediate wall, one is an air supply box 3 and the other is an exhaust box 4, and outside air is taken into the air supply box 3 by a fan 5. Exhaust gas is exhausted from the exhaust box 4, and in this example, the fan 5 is installed in each of the air supply box 3 and the exhaust box 4 and is driven in the opposite direction by a motor (not shown). By rotating, the outside air is taken in and the exhaust air is discharged.

The chamber 2 of the chamber fan 1 is provided with a large number of duct holes 6 on the side surfaces of the air supply box 3 and the exhaust box 4, for example, and the duct holes 6 are projected from the through holes to the outside of the chamber 2. By configuring it as a short tubular shape, for example, it is fitted with one end of the air supply duct 7 and the exhaust duct 8 in the longitudinal direction by a flexible duct, and is fixed by fixing means (not shown) such as fastening and bonding of bands. I am doing it.

The other ends of the air supply duct 7 and the exhaust duct 8 in the longitudinal direction are connected to an air supply port 9 such as an air supply grill and an exhaust port 10 such as an exhaust grill installed on the wall of each room. Yes, by this, air supply duct 7 and exhaust duct 8
Are arranged such that the chamber 2 of the chamber fan 1 and each room are directly connected to each other without branching in the middle in the longitudinal direction. According to the number of rooms, or a large number of them, including a space that can be regarded as a room by partitions such as entrances and bathrooms.

Of the many duct holes 6 in the air supply box 3 and the exhaust box 4, the remaining ones exceeding the number of the air supply ducts 7 and the exhaust ducts 8 are closed by fitting a cap (not shown). It is designed to do.

The air supply box 3 and its duct holes 6 are provided with negative ion generating means, whereby the air supplied from the air supply box 3 to the air supply duct 7 contains negative ions, and air is supplied. Mouth 9 and exhaust port 1
The air is supplied to the room from 0 to make the environment comfortable.

As the negative ion generating means, for example, an ionizer provided with a large number of electrodes 11 is used. In this example, the electrodes 11 are inserted into the respective duct holes 6 of the chamber fan 1, and the negative ions are generated from the electrodes 11 by energization. Is generated and negative ions are continuously supplied to the air passing through the duct hole 6.

The air volume adjusting means 12 is, for example, a damper or shutter for air volume adjustment, and is installed in each duct hole 6 of the chamber fan 1, for example, and is installed outside the tubular portion of the duct hole 6 for air volume adjustment. The opening and closing is controlled by the operation knob 13, and the air supply amount from each duct hole 6 of the chamber fan 1 to the air supply duct 7 is adjusted,
The amount of air supplied to each room can be optimized according to its area (volume).

At this time, in the chamber fan 1 of this example, the air flow rate adjusting means 1 is similarly provided in each duct hole 6 of the exhaust box 4.
2 is installed, the suction force to the exhaust box 4 is adjusted, and the amount of exhaust air from each chamber to the chamber fan 1 can be optimized in accordance with the above air supply amount.
