Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilation duct device equipped with a soft duct member, which is used in open animal breeding houses, gardening houses, various workshops, warehouses, and other buildings.

In recent years, temperature control in animal enclosures and other buildings has mainly been carried out through ventilation by opening and closing skylights and side windows, and by operating ventilation fans. Since a long hard duct is rotated by a drive motor to blow air, it requires a large amount of equipment cost and requires a certain level of building strength, which is impractical.

The present inventors have developed a blower duct device equipped with a lightweight and inexpensive soft blower duct member made of a film or sheet made of vinyl chloride, polyethylene, other plastics, or a material with the same effect as these. When used in buildings as long as 100 m, the ventilation duct is made of soft material and is made of a long length, making it difficult to rotate it to control the wind direction. As a result of various researches, the present invention was achieved.

The present invention provides ventilation control and variable temperature management in animal breeding houses, gardening houses, and other buildings, depending on the temperature in the house, the amount of air taken in, the wind speed, the popular direction, and the circulation of air in the house. It is an object of the present invention to provide a ventilation device equipped with a soft duct (soft air blowing duct device) that can blow air easily and efficiently.

This is a ventilation device equipped with a soft duct, characterized in that it is made of a sheet or film, or a soft duct made of a material having the same effect as these.

The soft duct is latched and fixed to the rotating member by one support wire, and the tip of the support wire has a rear end in the center of the bottom of the cylindrical soft duct bottom formed by the bottom forming member. , is removably locked and fixed to the center of the rear end opening of the rotating member, and is attached to the outer peripheral edge of the rear end opening of the rotating member.

In this embodiment, an indoor temperature sensor 17 is provided. For example, if the high temperature is set to 25°C and the low temperature is set to 15°C as the set temperature of the control panel 16, the indoor temperature will rise below 25°C. When the soft duct 1 is rotated so that the row of small through holes 2 are positioned downward as shown in FIG. 11 is activated, the damper 12 closes the upper wall opening 13 of the hard duct, and outside air or cold air is blown from the small ventilation hole 2 to the lower part of the building (see FIG. 9). Additionally, when the temperature inside the building falls below 25°C, the soft duct is reversed via the control panel in response to a command from the temperature sensor 17, and the row of small through holes 2 is placed upward (opposite to Fig. 1). , the damper 12 is fully opened (indicated by 12' in FIG. 1), and warm air from the upper part of the building is circulated through the small ventilation hole 2 and the opening 13 by the duct fan IIK. In addition, when circulating air inside the building, damper 1
It is possible to circulate indoor air by setting the opening degree of 2 to an appropriate degree and setting the outside air intake ratio to the desired ratio without fully opening the opening degree, and when the temperature inside the house falls below 15℃. Alternatively, the operation of the duct fan 11 may be stopped, or warm air may be blown by the duct fan 11 as appropriate instead of outside air.

In addition to indoor humidity sensors, outside air humidity sensors and switchboards can also be installed outside the building to maintain a good environment inside the building.

In addition, this device includes a humidity sensor, a power distribution board (control device M) K
Accordingly, each member can be automatically operated, but it can also be operated manually as appropriate.

Ventilation systems in conventional buildings are heavy rigid ventilation ducts made of metal pipes, PVC pipes, etc., which are long from 20m to 100m and connected to outside air intake rigid ducts equipped with duct fans. However, according to the present invention, the air duct not only uses a light and flexible air duct made of plastic film or sheet. It maintains its flexibility even when it is blown and filled with air, and the soft duct, which is difficult to rotate, can be easily reversed or stopped in response to temperature changes in the building. You can blow outside air upwards or downwards inside a building, stop introducing outside air and circulate the air inside the building, or mix outside air with the air inside the building and blow it. This allows the building environment to be maintained in good condition.
