Description

[Detailed description of the invention] The present invention relates primarily to greenhouse equipment for horticulture.

Conventionally, this kind of equipment has been known to improve the greenhouse effect as a double wall consisting of an outer chamber wall, an inner wall, an outer wall, and a ventilation gap between the two walls, which creates the entire greenhouse inside. Furthermore, there is also a type of this type that is equipped with a gas or other combustion heater inside the meditation room to improve the greenhouse effect, but in this case, the cough heater directs the combustion exhaust into the lagoon. In some cases, the exhaust air has a negative impact on plants! Although it has been proposed that the heater be of the so-called PIF type and the air supply and exhaust air be connected to the outside in order to make the heater completely hot, it has been proposed to be a type of heater that is connected to the outside. In such a method, combustion exhaust gas is discharged to the outside, resulting in a total loss of thermal efficiency.

The object of the present invention is to obtain a device which does not have such inconveniences, and is composed of an outer hard wall t, an inner wall, an outer wall, and a ventilation gap between both walls to create a greenhouse inside. According to the present invention, a combustion heater of gas or other gas is provided in the heating chamber, and the combustion exhaust gas 1 is guided into the ventilation gap through the inner wall and then discharged to the outside through the outer wall. 〇 Figures 1 to 5 show one example, and 11+ shows the greenhouse, (2) shows the outer wall of the greenhouse (1), and The presenting wall (2) is constructed as a double wall consisting of an inner wall (3), an outer wall (4), and a ventilation gap between both walls (51).

In this case, the outer wall (4) is made of, for example, a type in which glass is attached to the main body structure, and the inner wall (3) is made of, for example, a vinyl sheet, and is generally removable as necessary.

According to the invention, a gas or other combustion heater (6) is provided in the greenhouse (1), the combustion exhaust of which is introduced into the ventilation gap (5) through the inner wall (3). The outer wall of the hindlimb (4), which was opened and communicated with it, was completely opened so that it could be drained to the outside. To explain in detail everything shown in the figures, the heater (6) has a gas burner (6a) inside it, a heat exchanger (6b), and a circulation fan (
6o) The air is guided through f and configured in the Narita style.
It is equipped with an air supply port (7) and an exhaust port (8) connected to the heat exchanger (6b), and the air supply port (7) is connected to the cough wall (6b).
2), the exhaust port (8) shall open at one end of the ventilation section III (5), and the ventilation gap (5) shall communicate with the outside at the other end. Vent(
9) and an exhaust fan QO) inside thereof, so that the combustion exhaust gas is guided through the ventilation gap (5) from one end to the other, and then exhausted to the outside. During this time, the heat it held was used to heat the inside of the wire temperature M (11).

The growth of plants a in the greenhouse (1) can be promoted under an appropriate 002 concentration (for example, 150 pIMl), and in preparation for this, commercially available greenhouses have one ventilation gap (
5) in the appropriate place, for example, on the downstream side of the combustion exhaust.
Either a shutter 0υ communicating with the R greenhouse (1) is provided, or in this case, a shutter 0υ is provided inside the sales greenhouse (1). It is preferable to prepare a sensor α2 and control the opening and closing of the shutter Ql based on a signal for detecting the concentration. In the greenhouse (11), for example, as clearly shown in FIG. 2, partition walls Ql can be provided to divide the greenhouse into appropriate dimensions.

The cough heater (6) is not limited to the above-mentioned type, and may be of a type in which the cough air supply port (7) is opened into the meditation room (1), for example, as shown in the M4 diagram. As shown in the figure, it is also possible to adopt a type in which the exhaust port (8) is provided with an internal passage, an opening on the side thereof, and a zero-stage switching valve that selectively opens and closes. For example, the shutter 0 mentioned above
It's almost the same effect as υ, or it's kushimeru.

To explain its operation, when the combustion heater (6) is fully activated, not only the inside of the greenhouse (11) is heated and the temperature rises, but also the combustion exhaust is emitted through the ventilation gap (5) in the outer chamber wall 123. ) After the indoor heating is carried out, it is discharged to the outside, and the temperature inside the greenhouse (1) can be increased by the exhaust heat.

In this way, according to the present invention, a double wall Il'c having a ventilation gap is constructed in the entire interior of the outer circumferential chamber wall, and the combustion exhaust gas generated when the combustion heater is operated is guided to this. It is possible to eliminate the negative effects of exhaust gas and the decrease in thermal efficiency of the device.1 Its structure is simple, inexpensive, and has other effects.
