Abstract

PURPOSE:To facilitate the rotation of an air duct component, to secure uniformity of a posture of the soft duct component and to maintain a predetermined arbitrary air blow-off direction of ventilation of a duct, by a method wherein the rotation of a blowing fan is once suspended and inner pressure of the soft duct component is lowered, when the air blow-off direction of the ventilation of the soft air duct component is made to rotate at a different and arbitrary position. CONSTITUTION:At the time when an inside temperature of a house increasing from an appropriate temperature exceeds a predetermined temperature 25 deg.C of high level, action of a duct fan 6 is suspended by the instructions of a sensor 12 through a temperature controller 11 and a timer is operated. A soft blowing duct component 1 is made into an easily rotatable state by decreasing an inner pressure of said duct 1 through the suspension of the duct fan 6 and contracting the duct 1, and a driving motor 10 of the duct 1 is operated by a timer after the lapse of a fixed period of time for a decrease of the inner pressure and contraction of the duct 1. At the time when the duct 1 is made to invert, ventilation is performed within the duct 1 by retotating the duct fan 6, and the fresh open air or cool air is sent to the lower part of the inside of the house as said contracted soft duct 1 is formed in uniformity of a posture immediately.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention uses a blower duct device having a resin duct member to control the indoor environment (temperature management) method.

Conventionally, temperature control in general buildings has mainly been achieved through ventilation by opening and closing skylights and side windows, and by operating ventilation fans.Forcible ventilation using duct fans is the most effective method, but Fan devices are impractical because they require a large amount of equipment costs and require a certain amount of building strength because they rotate a long, hard duct made of iron or steel pipes using a drive motor to blow air. be.

Next, practical aspects of the present invention will be described.

The air duct system fft from Joki Kaga is used in a greenhouse for gardening, with the high temperature set at 25 degrees Celsius and the low temperature set at 13 degrees Celsius as f1 degrees at two high and low points set on the temperature regulator (control panel). did.

When the temperature inside the house exceeds the set temperature of 25°C, which is higher than the appropriate temperature, the duct fan is stopped and the timer is activated by a command from the sensor via the temperature controller (see Figure 6). When the duct fan stops, the internal pressure of the soft air blowing duct member decreases, and the duct contracts and becomes easy to rotate, and the timer starts the duct drive motor after a predetermined period of time for the internal pressure of the duct to decrease and contract. When the duct is activated and the duct is reversed (see Figure 2), the duct fan is rotated again to blow air into the duct, and the contracted soft duct is immediately formed into a uniform shape to absorb fresh outside air. Alternatively, cold air was blown inside the building to the lower blade (see Figure 3). Next, when the temperature inside the building drops and the soft ventilation duct member reverses or rotates below the set temperature, the operation of the duct fan is stopped as described above, the duct internal pressure is reduced, and the soft duct is appropriately contracted. After the duct was reversed, the duct fan was rotated again to blow air into the duct, and the contracted soft duct immediately formed into a bar-like shape to circulate indoor air from the upper blade inside the building. Fourth,
(See Figure 5). The above outside air or wind-resistant ventilation (see Figure 2)
In this case, the damper is configured to be closed, and in the case of an internal battle (1 ring transmission) (see Figure 4), the damper is configured to be fully opened (closed to outside air). Although the damper is shown in the figure, the opening degree of the damper can be automatically or manually set as appropriate so that the intake ratio of air inside and outside the building can be set as appropriate. Furthermore, when the temperature inside the building became 13° C. or lower, which was the lower set temperature (duct fan stop d - thirst), the duct fan was automatically stopped via the temperature controller.

In addition, when introducing outside air into the building, it is possible to not only introduce outside air but also cold air or warm air, and when the duct fan stops and the temperature reaches the normal temperature, the hotbed device is activated. It is also possible to easily manage the environment within the house in a complex manner.

Honji (In the example, it was used for gardening greenhouses, but it can also be used for animal breeding houses, various workshops, warehouses, etc., to control ventilation, change temperature VF! J4, etc.)

In addition, in response to changes in indoor temperature and humidity (/C), the air supply direction of the small hole in the soft duct member can be easily rotated to the desired position, and the opening degree of the damper and shutter can be adjusted. It can also be linked.

Note that although an indoor temperature sensor is used in the embodiment, an outside temperature sensor may also be used.

The present invention rotates or inverts a soft duct member, which is long in length from 20 m to loom, and is made of flexible thin material such as plastic or other film or sheet. There are many problems in rotating or inverting the soft duct while air is being blown out. For example, when a soft duct member is filled with air, it expands and the part held by the support becomes constricted.
It is very difficult to rotate it like this.

According to the present invention, when avoiding rotation of the soft duct part of the upper part of the duct, the operation of the duct fan is temporarily stopped, the internal pressure of the soft duct member is lowered, and the duct fan is contracted before being rotated. The soft duct member can be easily rotated without damaging it. When the duct fan is rotated again after the rotation or reversal is completed, the contracted soft duct member, which is rotated by the opening or the rotating member and is in a kinked state, immediately collapses due to the fact that the rear end is rotatably supported. As the duct returns to its original position, it enters the expanded state and is fixed to the support, allowing air to be blown out. In addition, the present invention can blow outside air, cold air, or warm air in any direction in which electricity is installed, in response to indoor temperature changes.

In addition, even when starting by blowing air to a soft duct member in a starting state where the opening has not been rotated or reversed and air is not being blown, the soft duct member must immediately maintain the attitude of the air duct. It is possible to do so.
