2. Description of the Related Art Conventionally, in a pond in a public plaza, etc., bubbles are generated in a fountain by a fountain installed in the pond to change the scenery in the vicinity. Landscape devices are known.

[0003]

However, such a conventional landscape device merely generates bubbles in the fountain and does not give an unexpected feeling to the viewer. It was not possible to express arbitrary patterns such as letters and letters.

The present invention has been made in view of the above situation, and it is possible to make an arbitrary pattern such as a character or a picture clearly appear in water by using bubbles, which is unexpected to a viewer. It is an object of the present invention to provide a display device using bubbles that can exert a staging effect such as giving.

[0005]

In order to achieve the above object, in a display device using bubbles according to the present invention, a plurality of diffused gas having pores for discharging bubbles is provided on at least one of a front side surface and a rear side surface. The plurality of diffused gases are connected to an air supply source via individual solenoid valves, respectively, while being arranged in parallel in a row in the width direction at the lower part of the water tank configured on the perspective surface. A controller is provided to control the opening and closing of the solenoid valve in the state where a uniform rising water flow is constantly generated in the water tank by discharging bubbles from the holes, respectively, and any one of the gas diffusers is selected. An arbitrary display pattern is made to appear on the see-through surface of the water tank by the bubble group discharged at the time.

[0006]

According to the present invention, for example, by periodically opening all the solenoid valves together for a short period of time, a row of bubbles emitted from a plurality of pores of diffused gas can be uniformly distributed in the water tank. Create a rising water flow. In this state, the controller controls the opening / closing of the solenoid valve for any one of the diffused gases in time, so that the bubble group released from the diffused gas at any time rises. Is formed, and this is displayed as a display on the transparent surface of the aquarium. Since this display pattern is composed of rising bubble groups, it is possible to give the viewer an unexpected feeling, and the rising bubble group is not disturbed and rises while clearly holding the display pattern. .
