Description

  The present invention relates to a flower pot automatic water dispenser for automatically supplying water to a flower pot from its bottom surface.

  Conventionally, various automatic watering devices for seed flowerpots have been known, but the basic configuration is that the water consumption by the plant in the flowerpot is from the flowerpot housing part, the water storage tank, and the water tank to the flowerpot housing part. It consists of a mechanism that automatically supplies water according to the volume. The mechanism for automatically supplying water is the most important, and the configuration greatly affects the function of the automatic watering device for flowerpots. As this mechanism, for example, a configuration is known that includes a water outlet with an opening / closing device that communicates with a flowerpot accommodating portion provided in the lower part of the water storage tank, and a water supply port with an opening / closing device provided in the upper part of the water storage tank.

  In this conventional example, first, the water supply port is opened, the water supply port is closed, water is supplied from the water supply port to the water storage tank, and then the water supply port is closed and the water supply port is opened. When the supply amount reaches a predetermined amount and the water outlet is submerged, the upper space in the water storage tank, which is shut off from the outside, becomes a pressure state lower than the external pressure, and the water discharge stops and is constant. The water level is maintained. On the other hand, when the plant in the flower pot consumes water and the water level falls and the water outlet is exposed, the water supply from the water outlet to the flower pot housing is performed again until the water outlet is submerged.

  According to the above-described conventional example, the opening / closing operation of the water outlet and the opening / closing operation of the water supply port need to be performed in a predetermined procedure before and after the water supply operation to the water storage tank. There is. In order to eliminate this complexity, conventionally, a water storage tank is formed with the wall surface of the planter case as a double structure, one space of the planter case divided into two by the partition wall is used as a flower pot accommodating space, and the other space is supplied to the water storage tank. A water supply space that is always open with the upper surface for water supply as a water supply port, the water storage tank and the water supply space communicate with each other through a water passage hole, and a partition water passage hole provided with an opening / closing device is provided below the partition wall. When opened, the water in the water supply space can be supplied to the flower pot accommodating space, and one end of the duct is in close contact with the vent provided in the upper part of the water storage tank, and the other end is disposed near the bottom surface of the flower pot accommodating space. A planter has been proposed (Patent Document 1).

  According to this planter, when water is supplied from the water supply port with the partition water passage hole closed, water accumulates in the water storage tank through the water supply hole from the water supply space. When opened, first, water in the water supply space flows into the flower pot housing space through the partition water passage hole, and if the water in the water supply space is insufficient, the water in the water storage tank passes through the water passage hole to the water supply space. When the amount of supply to the flower pot storage space reaches a predetermined amount and the lower end of the duct is submerged, the upper space of the water storage tank becomes a pressure lower than the external air pressure, and water supply from the water supply space stops. And a constant water level is maintained. On the other hand, when the plant in the flowerpot consumes water and the water level falls and the lower end of the duct is exposed, the upper space of the water storage tank communicates with the outside and water is supplied again until the lower end of the duct is submerged. As described above, according to the planter, since the opening / closing operation may be performed only by the partition water passage hole, the operation during the water supply operation becomes extremely simple.

  However, in the planter described above, when the lower end of the duct arranged near the bottom surface of the flower pot housing space is submerged, the water supply is stopped, and when the lower end of the duct is exposed and the space above the water supply tank communicates with the outside, the water supply is resumed. However, when the lower end of the duct is submerged, the water that has flowed into the duct does not completely flow out even if the water level in the flower pot housing space is lowered, and may remain in the duct. When such a situation occurs, even if the lower end of the duct is exposed, the space above the water supply tank does not communicate with the outside, so that water supply will not be resumed even though the water level in the flower pot housing space has decreased, and automatic water supply There is an inconvenience that is not performed. An object of the present invention is to solve this inconvenience and to provide an automatic watering device for a flowerpot that can be downsized and is easy to use while performing a reliable automatic watering operation.

Hereinafter, a preferred embodiment of the present invention will be described.
As shown in FIG. 1 to FIG. 4, the automatic water dispenser 1 for flower pots has a generally square shape in which the entire planar shape is formed in a rounded corner, and the flower pot accommodates a concave portion having a substantially circular shape at the center. Part 2 is provided. An annular water storage tank 3 that is closed by an inner wall 3a, a top wall 3b, an outer wall 3c, and a bottom wall 3d is provided so as to surround the flowerpot accommodating portion 2. As can be understood from FIGS. 3 and 4, the inner wall 3 a, the top wall 3 b, and the outer wall 3 c excluding the bottom wall 3 d are integrally formed with the bottom plate 2 a of the flower pot accommodating portion 2. On the other hand, the bottom wall 3d is in close contact with the bottom plate 2a, and is welded in a liquid-tight manner with a fitting protrusion provided in the periphery fitted in a fitting groove provided in a thick lower end surface of the outer wall 3c. ing.

  As shown in FIGS. 3 and 4, the bottom wall 3d is formed with recesses 4 and 5 that are recessed downward at two locations. As shown in FIGS. 2 and 3, the inner wall 3a portion corresponding to the recess 4 is recessed in the direction of the outer wall 3c, and a water supply mechanism is provided corresponding to the recessed portion. This water supply mechanism includes a cylindrical support 6 and a water supply pipe 9. As shown in FIGS. 3 and 4, the cylindrical support 6 passes through the bottom plate 2 a of the flower pot storage portion 2 corresponding to the recess 4, and communicates the flower pot storage portion 2 and the water storage tank 3 with the recess. 4, the inner peripheral surface is reduced in diameter and becomes thicker, and an internal thread 7 is formed on the inner surface corresponding to the flowerpot accommodating portion 2, and a part of the peripheral surface is cut out to form a water supply port 8. Yes.

  On the other hand, the water supply pipe 9 is substantially cylindrical as shown in FIGS. 3 and 4, and a male screw 10 that is screwed into the female screw 7 of the cylindrical support 6 is provided on the outer peripheral surface of the lower end portion. The lower end of the formed portion is reduced in diameter so as to correspond to the reduced diameter portion of the cylindrical support 6, and is screwed onto and supported by the cylindrical support 6. The water supply pipe 9 moves up and down with respect to the cylindrical support 6 according to the screwed state, and rises when rotating in a direction to release the screwed state, so that the reduced diameter portion at the lower end of the water supply pipe 9 becomes the water supply port 8. Correspondingly, a space is formed between the inner surface of the cylindrical support 6 and the outer surface of the water supply pipe 9, and the flower pot accommodating portion 2 and the inside of the water storage tank 3 communicate with each other through the water supply port 8. On the other hand, when the lower end of the water supply pipe 9 is tightly screwed to the cylindrical support body 9, they are brought into close contact with each other, the water supply port 8 is closed, and the flower pot accommodating portion 2 and the water storage tank 3 are shut off and become in a non-communication state. . A support plate 11 extending horizontally from the opening edge is integrally provided at the upper end of the opening of the water supply pipe 9, and a lid 12 is supported on the support plate 11 so as to be rotatable in the horizontal direction. The upper surface of the opening of the water supply pipe 9 is opened and closed.

  As shown in FIGS. 2 to 4, an air circulation port 13 is opened in the bottom plate 2 a of the flower pot accommodating portion 2 corresponding to the recess 5 and the inner wall 3 a of the water storage tank 3 continuous therewith. Correspondingly, the communication pipe fitting 14 is fixed. The communication pipe fitting 14 is a flat square shape, and is integrally formed on a mounting portion 14a composed of a double wall whose one side rises to form a side L shape, and on the back side of the rising portion of the mounting portion 14a. And a cylindrical pipe insertion portion 14b provided to communicate with the attachment portion 14a. Although not clearly shown in the figure, the mounting portion 14a is a substantially U-shaped flat surface projecting along the air circulation port 13 on the lower surface side of the bottom plate 2a, and the end portion on the inner wall 3a side is a support wall that is bent inward. The gap portion of the double wall is fitted and attached. And the said pipe insertion part 14b is located in the water storage tank 3, The lower end part of the communicating pipe 15 is inserted and fixed to this pipe insertion part 14b liquid-tightly.

  The upper end of the communication pipe 15 is located in the upper space of the water storage tank 3, and communicates the upper space of the water storage tank 3 and the flowerpot accommodating part 2 via the air circulation port 13. As can be understood from FIG. 5, the lower end opening surface of the communication pipe 15 is formed to be inclined. And although not clear in the figure, the lowermost end portion of the inclined opening surface is located on the back side, that is, the outer wall 3c surface side, and the upper end of the inclined opening surface is opposed to the air circulation port 13 formed in the inner wall 3a. . Further, a rib 16 extending straight along the inner surface from the lowermost end portion of the inclined opening surface is provided.

  Then, the usage method of this embodiment comprised as mentioned above is demonstrated. First, a flower pot that sucks up water from the bottom surface is accommodated in the flower pot accommodating portion 2, and the male screw 10 of the water supply pipe 9 and the female screw 7 of the cylindrical support 6 are closely screwed to the deepest part to close the water supply port 8. Then, the lid 12 is opened, and water is injected from the upper surface of the opening of the water supply pipe 9. The water injected into the water supply pipe 9 flows into the water storage tank 3 from the recess 4. Water injection is stopped when a desired amount that does not reach the upper surface of the communication pipe 15 is supplied into the water storage tank 3, and the water supply pipe 9 is rotated in a direction to release the screwing of the male screw 10 and the female screw 7. Release the blockage. As a result, when the water in the water supply pipe 9 flows into the flowerpot accommodating part 2 from the water supply port 8 and the water in the water supply pipe 9 runs out, the water in the water storage tank 3 flows from the water supply opening 8 to the flowerpot accommodating part. 2 flows in.

  Then, when the air circulation port 13 is submerged, water flows in above the inclined opening surface of the communication pipe 15 to close the inclined opening surface, and communicates with the outside (the flower pot accommodating portion 2) via the communication pipe 15. Since the upper space of the water storage tank 3 is cut off from the outside and is in a pressure state lower than the outside air pressure, the water supply from the water supply port 8 to the flower pot accommodating portion 2 is stopped. The water level at which the air circulation port 13 is submerged is the predetermined water level of the flower pot accommodating portion 2.

  The plant in the flowerpot consumes water, the water level in the flowerpot housing part 2 falls, the air circulation port 13 is exposed, the water in the communication pipe 15 flows out, and the upper space of the water storage tank 3 is outside (the flowerpot housing part 2). Since the upper space is in the same pressure state as the external air pressure, the water in the water storage tank 3 is supplied from the water supply port 8 to the flower pot accommodating portion 2. And if the water level of the flower pot accommodating part 2 rises and the air circulation port 13 is submerged again, and the inclined opening surface of the communication pipe 15 is blocked by the inflowing water, the outside (the flower pot accommodating part 2 is connected via the communication pipe 15. Since the upper space of the water storage tank 3 that has been in communication with the water tank is again cut off from the outside and is in a pressure state lower than the outside air pressure, the water supply from the water supply port 8 to the flower pot accommodating portion 2 is stopped. By repeating the above operation, a predetermined water level is always ensured in the flower pot accommodating portion 2, and automatic water supply becomes possible.

  When the above-described air circulation port 13 is exposed, the lower end opening surface of the communication pipe 15 is an inclined surface, so that the water that has been submerged in the air circulation port 13 and stopped at the lower end portion of the communication pipe 15 is Since it is easy to come off, the disconnection state between the upper space of the water storage tank 3 and the outside is surely performed. In addition, since the rib 16 is provided in the flow pipe 15, the water staying at the lower end of the communication pipe 15 flows down along the rib 16 and the release of the shut-off state is more reliably performed. .

  The present invention is not limited to the above-described embodiment. For example, the water supply mechanism is replaced with a cylindrical support body 6 in which the water supply port 8 is cut out, and a water supply pipe 9 that can be screwed up and down to the water supply pipe 9. Then, the water supply pipe 9 may be supported on the bottom plate 2a so that the water supply port 8 can be opened and closed according to the rotation, and the water supply pipe 9 is rotated so that the water supply port 8 can be opened to supply water. Further, it is sufficient that the rib 16 extends at least slightly above the inclined opening surface portion of the flow pipe 15.
