Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an air circulation system in a house for growing plants.

[0002]

2. Description of the Related Art Conventionally, house ventilation systems for ventilating air in a house for growing plants such as flowers and vegetables have been widely used. In this house ventilation system, fresh air is introduced into the house from the outside by a ventilation fan attached to a wall surface or a ceiling, and the air inside the house is replaced.

[0003]

The above-mentioned conventional house ventilation system can exchange the air in the house, but the air flow which eliminates the stagnation of the air which is uncomfortable for the person working in the house. Therefore, it is not possible to increase the work efficiency of a person working in the house or to promote the growth of plants.

Accordingly, an object of the present invention is to provide an air circulation system in a house that eliminates the stagnation of air that is uncomfortable for a person working in the house, improves the environment in the house, and promotes the growth of plants. Should be solved.

[0005]

To solve the above-mentioned problems, an air circulation system in a house is provided.
The configuration is as described in (1). According to the air circulation system in the house of the first aspect, when the fan is driven by the control means, the air in the house is circulated, so that the stagnation of the air is eliminated, and the environment in the house is improved. People who work in the office feel comfortable and can improve work efficiency. Further, since the air flow accompanying the air circulation in the house touches the leaf surface of the plant growing in the house, the respiratory action of the leaf is promoted, and the growth of the plant can be promoted.

According to the air circulation system in the house according to the second aspect, the direction in which air is sent from the fan can be set to a desired direction by the wind direction plate, so that it is easy to eliminate the stagnant portion of the air in the house. become.

According to the third aspect of the air circulation system in the house, when the insect in the house is approached by the luminous body and approaches the fan, the insect is sucked into the rotating fan from the air suction side of the fan and hit. To be killed. This makes it possible to reduce plant damage caused by insects.

[0008]

Next, an embodiment of the present invention will be described. Figure 1 shows a house 2 in a single house
1 is a perspective view showing an in-house air circulation system 1 to which four fans 3 for circulating air in the house are attached.
As shown in FIG. 1, the in-house air circulation system 1 is configured to generate a flow of air in the house 2 by rotating each fan 3 mounted in the house 2 to circulate the air. Each fan 3 draws in air from the rear,
Those that send out air from the front side and can send out air at a flow rate according to the volume of the house 2, the type of plant to be grown, and the like are selected.

FIG. 2 is a control block diagram of the air circulation system 1 in the house. A control circuit built in the control panel 3 supplies drive power to each fan 3 and controls the rotational drive of each fan 3. An operation unit 5 is provided on a panel surface of the control panel 4, and the operation unit 5 is provided with a switch for starting or stopping each fan 3 simultaneously or individually. Further, a timer for setting the time and driving each fan 3 in a timed manner is provided on the control panel 4, and a time setting knob is provided on the operation unit 5.

In the in-house air circulation system 1 configured as described above, when the simultaneous activation switch of the operation unit 4 is pressed, the four fans 3 are simultaneously activated. When each fan 3 rotates, the air in the house 2 is sucked in and sent out with pressure, so that an air flow is generated and the air is circulated.

FIG. 3 shows an air circulation path in the house 2. Although the air flow is shown only in the plane direction in FIG. 3, the air flow actually occurs in the vertical direction, so that the air is circulated in a direction not shown.

As described above, when each fan 3 is rotated, an air flow is generated in the house 2 and the air is circulated in the house 2, so that the stagnation of the air in the house 2 is eliminated. Thereby, the working environment of the person working in the house becomes comfortable, and the working efficiency can be improved.

Experiments have also shown that plant growth is promoted. The reason is considered to be that the air flow accompanying the air circulation in the house 2 touches the leaf surface of the plant growing in the house 2, so that the respiratory action of the leaf is promoted and the growth of the plant can be promoted.

Further, it has been found that so-called "unevenness" is reduced in the growth of plants, and that uniform growth can be achieved.

It has also been confirmed that the so-called "landing" of plants is improved. For example, when chrysanthemums are shipped as cut flowers, the fall of flowers is reduced and the shelf life is improved.

Furthermore, it has been confirmed that, for example, white rust, which often occurs on chrysanthemums, is extremely reduced.

FIG. 4 shows one of the fans 3 attached to the house 2. As shown in FIG. 4, a wind direction plate 6 for setting an air sending direction is attached to the front side (sending side) of each fan 3. This wind direction plate 6
Accordingly, the direction in which the air is sent from each fan 3 can be changed to a desired direction, so that the stagnation portion of the air in the house 2 can be easily eliminated. If the wind direction plate 6 is configured to be driven by electric power so that the air sending direction of each fan 3 can be changed by remote control, the house 2
The stagnation of the air inside can be more easily eliminated.

Next, an example in which a fluorescent lamp (not shown) is attached to the air suction side of each fan 3 will be described. When a fluorescent lamp is attached to the air suction side of each fan 3 and turned on at night, insects in the house 2 are invited to the fluorescent lamp. Insects approaching the fluorescent lamp are sucked into the fan 3 together with the air suction of the fan 3 and hit by the rotating body of the fan 3 to be killed. Thereby, it is possible to reduce the damage of plants by insects. It should be noted that another luminous body, for example, a mercury lamp or a sodium lamp may be used instead of the fluorescent lamp.

Since each fan 3 can be time-controlled by the timer as described above, if the fans 3 are intermittently driven, for example, at night when there are no people, it is possible to temporally adjust the growth of the plant.

The embodiment described above is an example, and does not limit the present invention. For example, the number of fans 3
Although it was explained as four, the volume of house 2, the type of plant,
One or more are used depending on various conditions such as temperature. Also, the rating of the fan used varies. Also,
The house 2 has been described as a single house type as shown in FIG. 1, but the internal house is circulated similarly to the single house type 2 in the continuous house type, and the house 2 is similar to the single house type 2. The operation and effect can be obtained.

The control panel 4 for controlling each fan 3
May be provided with an inverter to variably control the rotation speed of each fan 3. By changing the number of rotations of each fan 3, the house 2 is provided with an air flow rate corresponding to the type of plant.
The air inside can be circulated.

[0022]

According to the present invention, the environment inside the house is improved by eliminating the stagnation of air which is uncomfortable for the person working in the house, the work efficiency is improved, and the growth of plants is promoted. There is an effect that can be.
