Abstract

PURPOSE:To reduce running cost by changeably using electricity obtained from a generator using Diesel engine or gasoline engine as a power source for light in rooms or for heating. CONSTITUTION:When an engine 1 is started, a generator 2 is loated in relation therewith to generate electricity. When a changeover device 5 is change to X in daytime, electricity is transferred to light by a converter 4. Therefore, e.g. when a plant is reared in a house, artificial light irradiates the plant. When heating is required instead of light in the night, the changeover device 5 is changed to Y. As a result, cooling water of engine 1 passed through a heat exchanger 6 is heated by a heater 7 and then passed though the interior of house and returned to the engine 1 by a pump 8. Heating efficiency in the house is enhanced, because the cooling water is heated by discharge gas of engine 1 in the heat exchanger 6. Then the discharge gas is filtered by a poisonous gas-removing filter 9 and CO2 is fed into the house.

Description

[Detailed description of the invention] [Industrial application field] This invention relates to a house that requires light and heating.

[Conventional technology]

For example, it is common to use electricity for lighting the interior of a greenhouse for growing plants, and to provide a separate heating means for heating.

[Problems to be solved by this invention] However,
The above-mentioned means use commercial electric power and also require heating means, resulting in high running costs.

[Means for solving problems]

This invention provides a house that can reduce running costs, and takes the following technical measures.

That is, the house is configured such that electricity obtained from a generator 2 powered by a diesel or gasoline engine 1 can be switched to indoor lighting or heating via a switching means.

[Effect]

When the diesel engine or gasoline engine 1 is driven, this rotational power turns the generator 2 to generate electricity. When the switching means is set to light, electricity is converted to light to illuminate the room, and when the switching means is set to the heating side, electricity is converted to heat to heat the room.

〔effect〕

Since it does not use commercial electricity, running costs can be reduced. Also, for example, in a plant house, during the daytime,
When light is needed, electricity can be converted to light by switching the switching means, and at night, when light is not needed, electricity can be converted into heat by switching the switching means, so energy can be used efficiently.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

First, to explain its configuration, an engine (either diesel or gasoline) 1 installed in a plant factory 3 rotates a generator 2 to generate electricity. A conversion device 4 for converting electricity into light is installed inside the house.

The conversion device 4 is connected to the generator 2 via a switching device 5. 6 is a heat exchanger, 7 is a heater, and the heater 7 heats the cooling water of the engine 1 that has passed through the heat exchanger 6, and this heated water is supplied to the engine 1 by a pump 8. This is the configuration to return to. The exhaust gas from the engine 1 passes through the heat exchanger 6 and then enters the toxic gas removal filter 9, and CO2 is supplied into the room of the house 10.

To explain the configuration of FIG. 2, the cultivation device 10 includes left and right side walls 10a and a bottom wall 10 that connects the left and right side walls 10a.
It has a cultivation section consisting of b and #ll that supports this cultivation section. Reference numeral 12 denotes a planting board which is provided at the upper part of the cultivation section, spanning both side walls 10a and being detachable.
0a and the bottom wall 10b constitute the cultivation section in a substantially sealed manner. Reference numeral 13 denotes a liquid supply pipe provided at the upper center of the cultivation section, and the liquid supply pipe 13 is sandwiched between the liquid supply pipes 13 and nutrient solution is spouted toward the roots of the plants 14 provided on the planting board 12 at the left and right positions. A nozzle 15 is provided. Further, a humidity sensor 16 looking into the space of the cultivation section is provided on the side wall 10a. Note that the humidity sensor 16 and a nutrient solution supply means (not shown) are configured to be electrically related so that the supply time or supply interval of the nutrient solution can be adjusted based on the detection result of the humidity sensor 16. .

Next, the operation shown in FIG. 1 will be explained. First, when the engine 1 is started, the generator 2 starts to generate electricity. If it is now daytime, change the switching device 5 to
'', the conversion device 4 converts electricity into light. Thus, for example, when growing a plant in a greenhouse, artificial light illuminates the plant. Next, in the case of nighttime, heating may be needed more than light, and in this case, the switching device 5 is set to "Y". Then, the cooling water for the engine 1 that has passed through the heat exchanger 6 is heated by the heater 7 and then returned to the engine 1 by the pump 8 through the house. Moreover, since this cooling water is heated by the exhaust gas from the engine 1 in the heat exchanger 6, the heating efficiency in the house is increased. and,
The exhaust gas is filtered by a toxic gas removal filter 9, and CO2 is removed.
is supplied into the house.

Therefore, since commercial power is not used, running costs can be reduced. Moreover, by switching the switching device 5, it can be used for lighting and heating, which is efficient. and,
The use of cogeneration improves the running cost reduction effect.

In addition, in the embodiment, it was used for lighting and heating, but a part of it may be used as a power source for a motor or the like.

Next, the operation shown in FIG. 2 will be explained. When the humidity detected by the humidity sensor 16 is lower than the preset humidity, the nutrient solution supply means is activated.

The nutrient solution is ejected from the nozzle 15 of the liquid supply pipe 13 toward the roots of the plants 14 (see FIG. 3). In addition, as another means, if the water level is low as described above, the nutrient solution supply means is activated after a certain period of time has elapsed (see FIG. 4).

Furthermore, as another means, the detection by the humidity sensor 16 prevents the roots of the plant from becoming overly humid, so that rooting can be prevented and growth can be promoted.
