The automatic water refilling device for a cultivation container includes a water reserving tank 2 in which a flower pot 1 as a cultivation container is placed, and a water reserving tank 2 for storing water. And a replenishing container 3 for supplying water to the rehydration tank 2 from the replenishing port.

As shown in FIGS. 4 and 5, the water refill tank 2 has a substantially circular bottomed pot receiver 5 on which the flowerpot 1 is placed and a bottomed replenishment container installation part 6 on which the replenishment container 3 is placed. Any shape can be used as long as it can store water.

The bottom wall of the pot receiving portion 5 of the water tank 2 is provided with a flower pot 1 so that water in the water tank 2 can be easily absorbed from the hole 1 a provided at the bottom of the flower pot 1. A plurality of pot rests 7 are provided to hold the bottom of the water reserving tank 2 slightly above the bottom of the water refill tank 2. In addition, a holding portion 8 having a locking hole 8 a for locking and holding the replenishing container 3 is provided on the inner surface of the replenishing container setting portion 6 of the water refilling tank 2. It is to be noted that the pot rest 7 is not always necessary, and it is sufficient if there is a space through which water can enter between the bottom of the cultivation vessel such as the flowerpot 1 and the inner bottom of the water tank 2. Further, a drain hole 9 that can be used to drain the water inside is formed on the side wall surface of the bowl receiving portion 5 of the water refill tank 2, and a drain plug 10 that opens and closes the drain hole 9 is detachably attached. I have.

The replenishing container 3 is a container main body 1 1 for supplying replenishing water to be supplied to the water refill tank 2 and an air release means for releasing the upper part of the container main body 11 to the atmosphere when the water level of the water refill tank 2 drops. An open air pipe 12 is provided.

As shown in FIGS. 6 to 8, the container body 11 of the replenishing container 3 has a hollow interior, and has an air intake pipe 13 connected to the atmosphere release pipe 12 on the upper side. Is formed at the bottom, and a supply port 14 for supplying water inside the water tank 2 is formed at the bottom, and between the supply port 14 and the inner bottom surface of the water tank 2 in the installed state on both sides of the bottom. A leg 15 for forming a gap is provided, and a locking member 16 to be inserted into a locking hole 8 a of the holding portion 8 of the water refill tank 2 is provided on the back surface. If the supply port 14 is provided on the lower side of the container body 11, it is not necessary to provide the legs 15. The open air pipe 12 is not particularly limited as long as it is a tubular member made of resin, metal, rubber, or the like, and includes all members called pipes, tubes, hoses, and the like. The open-to-atmosphere pipe 12 has one end communicating with an air intake 13 formed at the top of the container body 11 and the other end (tip) in an open state. The open end of the air release pipe 12 can be put into the water stored in the water refill tank 2 when the water replenishment tank 2 is in use. It only needs to be long enough to be released.

Here, the container body 11 and the open-air pipe 12 are integrally formed by resin molding. The container body 11 and the air release pipe 12 are previously formed separately, and the air release pipe 12 is connected to the container body 11 by bonding, welding, or the like to connect the supply container 3 to the container body 11. It can also be configured.

In addition, since the retaining member 16 of the replenishing container 3 is configured to only be inserted into the retaining hole 8a of the holding part 8 of the water reserving tank 2, the retaining member 16 is provided even when the entire replenishing container 3 is raised. Is formed so as not to fall out of the locking hole 8a. It is needless to say that the means for locking the supply container 3 and the water refill tank 2 is not limited to such a configuration, and a configuration in which the replenishment container 3 is detachably fixed and held on the water collecting tank 2 side is adopted. Can also be used.

Next, the operation of the automatic water refilling device configured as described above will be described mainly with reference to FIGS. 2 and 3.

First, the pot 1 in which the plants are planted is placed in the pot receiving section 5 of the water tank 2 and the water is stored in the water tank 2 (the water in the water tank 2 is referred to as “water W l” for the sake of explanation). .). In addition, water is also poured into the container body 11 of the replenishing container 3 (the water in the container 11 is referred to as “water W 2” for explanation), and the water is supplied downward to the replenishing container setting part 6 of the refill tank 2. With the supply port 14 facing downward, and the locking member 16 of the container body 11 is inserted into the locking hole 8a of the locking portion 8 of the water reserving tank 2 and locked and held.

At this time, the leading end (lower end) of the open-to-atmosphere pipe 12 connected to the container body 11 of the supply container 3 should be put into the water W 1 stored in the water refill tank 2. In order to install the replenishing container 3, the tip of the open-to-air pipe 12 is supplemented with water filled in the container body 11 while closing the open end of the open-to-air pipe 12 with a finger or the like. You only have to put it in water in aquarium 2.

In this state, the distal end (lower end) of the open-air pipe 12 leading to the upper space S of the water W 2 in the container body 11 of the collection container 3 is placed in the water W 1 stored in the rehydration tank 2. Because of this, the end of the atmosphere release pipe 12 is the same as being sealed. Therefore, the water W2 put in the container body 11 of the supply container 3 is kept as it is, and does not flow out from the lower supply port 14 below.

After that, the water in the water tank 2 is taken up from the hole 1a provided at the bottom of the flowerpot 1 from the soil 1b inside the water tank 1 and absorbed by the plants and the like. Water W 1 decreases and its level decreases. Therefore, as shown in FIG. 3, the water level W 1 in the position shown by the solid line is reduced to the water level w 2 in the position shown by the phantom line by reducing the water level of the water W 1 in the rehydration tank 2 and lowering the water level. When it descends, the tip of the open-air pipe 12 of the supply container 3 that had been in the water W1 comes out above the water surface.

Then, the replenishment container 3 is drawn into the upper space S in the container body 11 as indicated by an arrow, and the water W 2 of the container body 11 is It flows out of the refill port 14 into the water tank 2, Water is replenished in the water tank 1 2. Then, when the water level of the water W 1 in the water refill tank 12 rises and the tip of the regenerating air release pipe 12 enters the water W 1 in the water refill tank 12, the water release pipe 12 re-opens. When the opening at the distal end is in the same state as when the opening is sealed, the outflow of the water W2 in the container body 11 stops, and that state is maintained.

In this way, the water level in the refill tank 2 drops → the atmosphere is released → the water in the container body 1 1 flows out to the refill tank 2 → the water level in the refill tank 2 rises → the air is shut off—the water in the container body 11 is replaced The cycle of stopping the outflow to the water tank 2 is repeated every time the water level in the water tank 2 drops, and the required amount of water is constantly replenished in the water tank 2 and watering to the flowerpot 1 is automatically performed. It is.

As described above, this automatic water refilling device has a water storage tank in which a cultivation container is placed and a water storage tank in which water can be stored. Since a water supply container is provided, water can be automatically supplied to the cultivation container with an extremely simple configuration, and the size and cost can be reduced.

As a result, this automatic water replenishment eliminates the need to carry out port water work manually every day, especially when the outside temperature is high, such as in summer, and keeps the house absent for a long period of time. Also becomes possible. It also saves water when it is not absent, and saves water. In addition, it is easy to grow wild grasses by using a lot of sunshine sand, pumice stone, Fuji sand, river sand, etc. as soil for cultivation containers such as flowerpots. Furthermore, since the water refill tank can be made open, the water is less likely to rot and the roots do not die.

Next, FIG. 9 is a front sectional view showing another example of the automatic water refilling device for a cultivation container according to the present invention, and FIG. 10 is a side view of the water refilling device.

The automatic water refilling device for a cultivation container has a water reserving tank 32 on which a flower pot 31 as a cultivation container is placed, and a water reserving tank 32 that can store water, and the upper part of the water is released to the atmosphere when the water level in the water refilling tank 32 drops. And a replenishing container 33 for replenishing the rehydration tank 32 with water from a replenishing port below the replenishing port.

The flowerpot 31 has a mesh-shaped hole 31a at the bottom. By forming the holes 31a in a mesh shape in this way, the water can be uniformly distributed throughout the pot. At the same time, a net that does not drop the soil becomes unnecessary, and the soil can be directly put into the pot. The cultivation container to which this automatic water refilling device can be applied is not limited to this.

The water reserving tank 3 2 is formed integrally with a storage section 3 4 for storing the flowerpot 3 1 and a replenishing container installation section 3 5 also serving as a replenishing section for enabling water to be supplied from the outside. A large number of ventilation holes 36 communicating inside and outside are formed, and a notch 37 is formed in the lower part of the storage part 34 to allow water to be supplied from the supply container installation part 35. . The shape of the storage section 34 is not limited to the shape of a flower pot, but may be any shape as long as it can accommodate a cultivation container. Other configurations are the same as those of the water tank 2 of the above embodiment.

On the other hand, in the supply container 33, the supply port 14 below the container body 11 is formed on the lower side, eliminating the need to form a gap with the inner bottom surface of the water supply tank 32 and eliminating the legs. The other configuration is the same as that of the supply container 3 of the first embodiment.

The same effect as that of the first embodiment can be obtained in the automatic water refilling device configured as described above. At the same time, the storage section 3 4 is integrally formed in the water tank 3 2 to form a double flower pot, so that the plant pot 3 1 does not burn due to strong direct sunlight in summer etc. Can be prevented. In addition, since a large number of ventilation holes 36 are formed in the housing section 34, the cooling effect is increased in combination with the evaporation of water, the direct heat in summer is reduced, and the flowerpot 31 is protected from heat. It can protect the roots of the plants, and draining water in winter can improve the heat retention effect. Furthermore, by mixing the soil for flowerpots with other soil, such as sunshine sand, pumice stone, Fuji sand, and river sand, it is possible to easily grow wild grasses and plants in cold regions.

In this case, a flower pot in which the flower pot 3 1 and the water tank 3 2 are integrated, that is, a water tank that can store water at the bottom of the flower pot body is provided integrally, and the water tank is filled with water outside the flower pot body. It is also possible to construct a flower pot with a water supply part. With such a flower pot, the automatic water supply device according to the present invention can be configured to obtain a flower pot capable of automatic water replenishment.

Then, the main body of the flowerpot is replaced with the housing part 3 4 of the flowerpot 31 and the water tank 3 2 of the above embodiment. A double flowerpot consisting of: the inner wall is the flowerpot 31 and the outer wall is the housing

By providing a flowerpot body equivalent to 34, an automatic water supply device according to the present invention can be configured to perform automatic water refilling, and a flowerpot having the same effect as the case where the above-described housing portion 34 is provided is obtained. be able to.

Also, as shown in FIG. 11, by using a flower pot 38 provided with a vent hole 39 as a flower pot to be stored in the storage portion 34 of the water reserving tank 32, the same operation and effect as in the second embodiment can be obtained. In addition, it will be possible to grow alpine plants. Therefore, the automatic water supply device according to the present invention is configured by forming the flowerpot 38 integrally with the water reserving tank 32 to form a double flowerpot having vent holes formed in the inner wall and the outer wall. Automatic water replenishment is possible, and the same effect as in the case where the storage section 34 is provided can be obtained, and a flower pot capable of growing alpine plants can be obtained. Next, FIG. 12 is a front sectional view of an essential part showing an example of a water tank for a cultivation container according to the present invention, and FIG. 13 is a plan view of the water tank of FIG. ―

The water refilling tank 55 has a replenishing container installation part 6 integrally formed with the bowl receiving part 5, and a hollow holding part 56 is provided at the inner bottom of the replenishing container installation part 6. Ports 5 and 6 are the refill ports for bottle-shaped refill containers 42 such as pet bottles

4 4 3 A screw portion 57 formed on the outer periphery is formed with a screw portion 57 on which the screw portion 43 can be screwed. The holding portion 56 has a hole communicating with the inside and outside or an opening formed by a cutout portion. The part 58 is formed at one or more places.

Here, the hollow holding portion 56 may have any cross-sectional shape. Further, the hollow holding portion 56 may be provided integrally with the water refill tank 55, or may be formed separately from the water refill tank 55 to form a hollow holding member. The holding member is fixed to the inner bottom portion of the water refill tank 55 by bonding with an adhesive, or by welding, fusion, or the like, or a screw is formed on the outer peripheral surface of the holding member to be hinged to the water refill tank 55. be able to. Further, the holding portion 56 can be held by inserting the mouth portion 43 of a bottle-shaped replenishing container 42 such as a bottle without forming the screw portion 57.

Also in the water reserving tank configured as described above, the flowerpot 1 is placed, and the water-supplying container 42 such as a PET bottle is filled with water and attached to the holding portion 56. this In this state, the water in the water tank 55 decreases due to the water in the water tank 55 being sucked up from the soil in the flowerpot 1 and being absorbed by plants, etc., as well as evaporating naturally. Decrease. Then, the water level of the water refilling tank 55 drops, and the opening 58 of the hollow holding part 56 is opened to the atmosphere, so that the air flows from the mouth of the supply container 42 through the opening 58 to the inside. Of the supply container 42, the water in the supply container 42 flows out into the holding part 56, flows out of the opening 58, and flows into the water tank 55 to be replenished. When the water level of 5 rises and the opening 58 of the hollow holding part 56 falls below the surface of the water, the supply of water from the supply container 42 to the water catching tank 55 stops.

In this case, the water level in the holding part 56 is also opened due to the drop in the water level in the water tank 55.

The height is changed to the same height through 5 8, and the surface tension from the top of the water in the holding section 5 6 and the rehydration tank 5 in the holding section 5 6 5 When the surface tension breaks up and down in the holder 56, the air flows into the supply container 42 through the opening 58 in the holder 56 and the container 42 The inside is opened to the atmosphere, and the water in the supply container 42 flows into the water refilling tank 55.

In this way, even if the water level in the water refill tank 55 drops, the state in which water is connected is formed by the surface tension of the replenishing container 42 and the surface tension of the water in the holding part 56, so that the hollow holding part is formed. The opening of the opening 56 cannot be opened to the atmosphere unless the height of the opening 58 is longer than the surface tension of the supply container 42 side.

Therefore, the same operation and effect as described in the first embodiment of the automatic water refilling device for a cultivation container can be obtained. In addition to this, when a container body having a threaded portion such as a bottle is used for the container body 43 of the supply container 42, the container body 43 (pet bottle) is turned upside down and the holding portion of the water supply tank 55 is held. 56 By screwing to the inner peripheral surface, the container body 43 can be easily and stably held in the water refill tank 52. In addition, it is possible to effectively reuse pet bottles, for which recycling has recently been called for, which has the enormous effect of using resources.

The shape of the water refilling tank 55 is not limited to the shape shown in Fig. 13; for example, as shown in Fig. 14, when the bowl is Apply to gourd shaped or square pot as shown in Figure 15 In the case of the container, the replenishing container installation part 6 was arranged in a biased shape, and as shown in Fig. 16, the replenishment container installation part 6 was arranged on both sides of the bowl receiving part 5 respectively. As shown in FIG. 17, a plurality of replenishing container installation sections 6, 6 may be arranged on one side of the pot receiving section 5, respectively.

Next, FIG. 18 is a front cross-sectional view of an essential part showing another example of a water tank for a cultivation container according to the present invention, FIG. 19 is a plan view of an essential part of the water tank of FIG. 18, and FIG. It is a front view of 9 supply containers.
