[0001] The present invention utilizes the change in air temperature during the day, and automatically expands the air inside the container every day by extruding a part of the water in the container as the air in the container expands thermally with the rise in temperature. The present invention relates to an automatic watering device for watering plants.

【0002】(イ)従来、タイマー制御により毎日自動
的に水やりをする自動水やり器はあった。 (ロ)しかしタイマーによる制御のため植物が必要とす

[0002] Conventionally, there has been an automatic watering device for automatically watering every day by a timer control. (B) However, a constant amount of water was supplied irrespective of the amount of water required by the plant due to the control by the timer. (C) For this reason, water is often supplied more than necessary,
Fertilizer was washed away when excess water flowed out. (D) When the excess water stayed around the roots of the plant without flowing out, root rot occurred. (E) The price is high because a timer is used. There was a disadvantage.

【0003】さて、一般に気温は一日を周期として昼間

In the automatic watering apparatus according to the present invention, when the temperature rises during the temperature cycle of the day, the air in the container thermally expands due to the rise of the temperature of the container heated by the rise of the temperature and the temperature inside the container. Water the plants by pushing some of the water out of the container.

【0005】水やりは、気温が上昇を続ける間継続し、
気温の上昇が止り容器内外の圧力が等しくなったときに
止まる。
Watering continues as the temperature continues to rise,
It stops when the temperature stops rising and the pressure inside and outside the container becomes equal.

【0006】そして、気温が下降するときには、容器の
温度下降と共に、容器内の空気が収縮し、押し出した水
に代えて、容器外の空気を容器内に取り込む。
When the temperature drops, the air inside the container shrinks as the temperature of the container drops, and air outside the container is taken into the container instead of the extruded water.

【0007】空気の取り込みは、気温が下降を続ける間
継続し、気温の下降が止まり容器内外の圧力が等しくな
ったときに止まる。
[0007] The intake of air continues while the temperature continues to decrease, and stops when the temperature stops decreasing and the pressures inside and outside the container become equal.

【0008】この様にして気温が上昇するときに水やり
をし、気温が下降するときには、容器内に空気を取り込

少なくなる。
When this automatic watering device is installed in a place exposed to sunlight, the temperature of the container becomes higher when the solar radiation is strong, and the thermal expansion of the air in the container increases.
More water can be given to the plants. When the sunshine is weak, the temperature rise is small and the amount of water given to the plants is small.

【0010】一方、植物は一般に日射しが強いときに多

要とはしない。
[0010] On the other hand, plants generally require a lot of water when the sunlight is strong, and do not need much water when the sunlight is weak.

【0011】すなわち、この自動水やり器は植物が多く
の水を必要とするときには多くの水を与え、多くの水を
必要としないときには与える水の量も少なくなる。
That is, the automatic watering device provides a large amount of water when the plant needs a large amount of water, and also provides a small amount of water when the plant does not require a large amount of water.

【0012】また、この自動水やり器は自然界の温度変

Description of the operation of watering (a) The container (1) contains air (2) and water (3). (B) A pipe (4) integrated with the float (6) is floating on the surface of the water (3). (C) There is a hole (5) on the side surface of the pipe (4). Hole (5)
Due to the function of the float (6), the hole (5) in the water near the water surface connects the inside and outside of the container. (E) When the pressure inside and outside the container is equal at the position of the hole (5), the water (3) is blocked by the hole (5) due to the surface tension of the water and leaks out of the container through the hole (5). There is no. Since the hole (5) is filled with water, no air outside the container enters the container. (F) Now, when the container (1) is warmed due to a rise in air temperature, the temperature of the air (2) in the container naturally rises and thermally expands. (G) The air (2) in the expanded container is the water (3) in the container.
Pressurize the water surface. (H) Part of the water (3) in the pressurized container is pushed out of the container through the hole (5) due to surface tension. ) Is dropped by its own weight into the pipe of (9), the water guide tube (9), and the watering port (1).
0), plants are watered through a watering tube (11). (U) When the temperature rise stops and the temperature rise of the container (1) stops, the thermal expansion of the air (2) in the container stops. When the pressure inside and outside the container becomes equal at the position of the hole (5), the water (3) in the container is blocked by the hole (5) due to surface tension, and watering stops.

Description of the operation for taking in air (a) When the air temperature starts to decrease, the temperature of the container (1) decreases, the air (2) in the container contracts, and the pressure in the container at the position of the hole (5) is reduced. Lower than outside the container. (B) Due to the pressure difference between the inside and outside of the container, the air outside the container comes out of the air inlet (7) due to the surface tension of water in the hole (5).
The gas enters the container via the suction tube (8) and the hole (5). (C) The entered air rises as bubbles in the water (3) in the container and is taken into the air (2) in the container. (D) When the temperature drop stops and the temperature drop of the container stops, the contraction of the air (2) in the container stops. When the pressure inside and outside the container becomes equal at the position of the hole (5), the hole (5) is closed by the surface tension of the water (3) in the container, and the inflow of air outside the container stops.
