Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fountain device mainly installed indoors.

[Prior Art] This type of indoor fountain device generally stores water in a water storage section 51 through a nozzle 5, as shown in FIG.
A lower unit 50 has a built-in submersible pump 53 for pumping water to
An intermediate unit 60 is formed of a transparent cylindrical body, which is fluid-tightly connected to the main body, and forms a fountain space 61 that extends upward. It consists of an upper unit 70 containing a lighting fixture 71 that emits light.

[Problem to be solved by the invention] In the conventional fountain device, the luminance is increased by projecting light from the illumination device 71 onto the fountain column in which water flows from the nozzle 52 into the fountain space 61. The fountain column can be viewed from a wide-angle area around it through the intermediate unit 60 made of a transparent cylinder. Therefore, it creates an extremely elegant atmosphere that can be enjoyed to the fullest, so it is often used as an indoor fountain device.

However, because the viewer is limited to the fountain pillar, the visual changes are somewhat poor, and the dynamic elements are insufficient, so the problem is that the ability to actively arouse attention is low. have.

The present invention was developed in light of these circumstances, and like conventional fountain devices, it not only provides an elegant atmosphere, but also actively attracts attention by incorporating visual changes and dynamic elements. The purpose of the present invention is to provide a fountain device equipped with a fountain model that can improve the arousal performance.

[Means for Solving the Problems] A fountain device equipped with a fountain model of the present invention includes a lower unit provided with a water storage part for storing fountain water and equipped with a fountain water pressure pump in the water storage part, An intermediate unit is formed of a transparent cylindrical body which is attached in a removable and fluid-tight manner and extends upward, and a light beam is attached to the upper part of the intermediate unit and projects light into the interior of the cylindrical body towards the fountain space. The fountain device is equipped with an upper unit that has a built-in illumination device, and is equipped with a model support cylinder consisting of a plurality of cylinders that are integrally connected in a liquid-tight manner so as to be able to slide and expand with a predetermined stroke amount. The lowermost cylindrical body of the support cylinder is installed in communication with the discharge system of the fountain water pressure pump inside the lower unit,
A fountain model consisting of a base equipped with a fountain nozzle at the upper end of the uppermost cylindrical body and dolls arranged in a row on this base is removably attached, and the hollow part of the model support tube serves as a water supply passage for the fountain nozzle. and the fountain water pressure pump is used both to supply water to the fountain nozzle through the hollow part of the model support cylinder and to supply water to the hollow part for controlling the extension of the model support cylinder. .

[Function] In this invention, when the water pressure pump for the fountain is operated, water in the water storage section is supplied to the model support tube through the discharge system, and the model support tube expands, so the fountain model figure starts to rise. At the same time, the hollow part of the model support cylinder functions as a water supply passage, so that water is also supplied to the fountain nozzle of the fountain model, and water is ejected from the fountain nozzle. Therefore, the fountain model rises while spraying water from the fountain nozzle. When the amount of water supplied by the pump is large, the model support tube expands at high speed and a large amount of water is spouted from the fountain nozzle. Furthermore, if the pump is stopped, the water in the hollow part of the model support tube is drained, the model support tube contracts, and the fountain model doll descends accordingly. Furthermore, if drainage and water supply to the hollow part of the model support tube are carried out simultaneously, the model support tube will expand or contract at a speed corresponding to the ratio of the amount of water discharged and the amount of water conveyed. When the model support cylinder generally contracts, the fountain model descends while spouting water from the fountain nozzle.

In particular, since the model support tube is of a multi-stage type consisting of a plurality of cylinders that are slidably, telescopically and liquid-tightly connected, the vertical length and elongation of the model support tube in the contracted state are improved. The effect is that the difference between the vertical length of the model support tube and the vertical length of the model support tube, that is, the stroke, can be made extremely long. The fountain model is installed in communication with the inside of the unit, and the fountain model is attached to the upper end of the uppermost cylindrical body, so that the fountain model can be moved up and down between the lower unit and the fountain space above it. These effects work together to raise the fountain model from a low level corresponding to the lower unit to an extremely high position above it, or to raise it from an extremely high position above the lower unit. The effect is that it becomes possible to lower the level to a low position corresponding to the level.

In this way, by making the model support tube multi-stage, even if the model support tube is made smaller during contraction and the overall height of the fountain device is kept low, it is possible to make the fountain model dynamic by increasing the vertical stroke of the model support tube. It will be possible to move it up and down.

Furthermore, in the present invention, the water supply for extending the model support tube and the water supply for spouting water from the fountain nozzle of the fountain model can be performed by the same pump, so the pump is not necessary. This makes it possible to minimize the number of fountain devices, which helps to make the fountain device more compact and lower in price.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

FIG. 1 is a schematic vertical sectional view of a fountain device equipped with a fountain model according to an embodiment of the present invention. In the figure, a fountain device 1 is composed of a lower unit 2, an intermediate unit 3, and an upper unit 4.

The lower unit 2 has a water storage section 21 for storing fountain water.
and a mounting flange 2 on the outer periphery of the upper end opening.
2, and a fountain water pressure pump 23 installed in the water storage portion 21 of the bottomed cylinder 24.

The intermediate unit 3 is made of, for example, a transparent acrylic resin plate or the like, and is formed into an elongated cylinder with a circular or polygonal cross section and is open at both upper and lower ends. The flange portion 31 is attached to the flange portion 2 of the lower unit 2.
2 through a gasket 5, and by tightening both 2 and 3 with a plurality of bolts 6, it is connected to the lower unit 2 and is detachably and fluid-tightly attached.

The upper unit 4 has an opaque cap-shaped cover 4
1 and is installed inside this cap-shaped cover 41, and is installed inside the intermediate unit 3, that is, the fountain space 32.
It is composed of a lighting device 42 that projects light toward the
It is attached to the upper part of the intermediate unit 3.

The model support cylinder 7 includes a plurality of cylinders 7 that are integrally connected in a liquid-tight manner so as to be slidable and telescopic at a predetermined stroke amount.
1, 72, and 73 in a multi-stage structure, and the lowermost cylinder 71 in the model support cylinder 7
is attached to the discharge system 23A of the fountain water pressure pump 23 in communication with the inside of the lower unit 2, and communicates with a base 82 provided with a fountain nozzle 83 at the upper end of the uppermost cylindrical body 73. A fountain model 8 consisting of an idol doll 81 like Goku is detachably attached. The hollow part of the model support cylinder 7 is connected to the fountain nozzle 83 as a water supply passage, and the fountain water pressure pump 23 supplies water to the fountain nozzle 83 through the hollow part of the model support cylinder 7 and the model support cylinder. It is also used to supply water to the hollow portion for controlling the extension of No. 7.

The lower unit 2 and the upper unit 4 are configured to communicate with each other through a pipe 9, and a power supply line 10A extending from a terminal plate 10 installed in the upper unit 4 passes through the pipe 9 to connect the motor of the water pressure pump 23 for the fountain. The other power supply line 10B extending from the terminal board 10 is electrically connected to the lighting device 42. Note that 11 in the figure indicates a power supply circuit.

Next, the operation of the above configuration will be explained.

When a start switch (not shown) provided in the power supply circuit 11 is turned on to operate the fountain water pressure pump 23, water in the water storage section 21 is supplied to the model support cylinder 7 through the discharge system 23A of the pump 23. The model support cylinder 7 is then extended. In parallel with this, the hollow part of the model support cylinder 7 functions as a water supply passage, so that water is also supplied to the fountain nozzle 83 of the fountain model 8, and water is ejected from the fountain nozzle 83. Therefore, the doll 81 of the fountain model 83 is the fountain nozzle 8.
It rises while spouting water from 3. When the amount of water supplied by the pump 23 is large, the model support tube 7 expands at high speed and a large amount of water is spouted from the fountain nozzle 83. Additionally, if the pump 23 is stopped, the water in the hollow part of the model support tube 7 is drained and the model support tube 7 contracts, and the fountain model 8
doll 81 descends. Furthermore, if drainage and water supply to the hollow part of the model support tube 7 are carried out simultaneously, the model support tube 7 will expand or contract at a speed corresponding to the ratio of the amount of water discharged and the amount of water conveyed, and in that case, When the model support tube 7 contracts at a higher speed than the speed corresponding to the displacement, the fountain model 8 descends while spouting water from the fountain nozzle.

In particular, since the model support tube 7 is multistage, it is possible to make the stroke amount extremely long, and the fountain model 8 can be raised and lowered between the lower unit 2 and the fountain space 32 above it. These effects work together to raise the fountain model 7 from a low level position corresponding to the lower unit 2 to an extremely high position above it, or from an extremely high position above the lower unit 2 to the lower level. It becomes possible to lower the unit to a lower level corresponding to unit 2. For this reason, even if the model support tube 7 during contraction is made smaller to keep the overall height of the fountain device 1 low, the fountain model 8 can be moved up and down dynamically by increasing the lifting stroke of the model support tube 7. Become.

Furthermore, since the structure is such that the water supply for extending the model support tube 7 and the water supply for spouting water from the fountain nozzle 83 of the fountain model 8 can be performed by the same pump, only one pump 23 is required. This helps in making the fountain device 1 more compact and reducing its cost.

Furthermore, since it is technically easy to color fountain water, desired colored water is supplied to the fountain nozzle 83.
By using fountains from the ground, it is possible to create a unique complex atmosphere with a variety of colors.

According to the present invention, the model support cylinder has a structure in which a plurality of cylinders are integrally connected in a slidable and telescopic multi-stage manner, and the lowermost cylinder is connected to the discharge system of the water pressure pump for fountains in the lower unit. We adopted a structure in which a fountain model consisting of a base with a fountain nozzle attached to the upper end of the uppermost cylinder and a doll connected to this base was installed in communication with each other internally, so the fountain model could be connected to the lower unit. It is now possible to raise the fountain from a low level position corresponding to the lower unit to an extremely high position above it, or to lower it from an extremely high position in the fountain space to a low level position corresponding to the lower unit. This enables dynamic performances. Although it is possible to make such a dynamic performance possible, by configuring the model support tube in multiple stages, the overall height of the fountain device can be kept low, which is an extremely beneficial effect.

In addition to this, the fountain water pressure pump is configured to both supply water to the fountain nozzle included in the fountain model and to supply water to control the extension of the model support tube, allowing a wide variety of dynamic effects to be created. However, only one pump is required, which significantly promotes compactness and cost reduction.
