Description

  The present invention relates to a display device that visualizes a flow of a fluid and displays it as a pattern, a display device unit, and a decoration, furniture, or fitting using the same.

  Conventionally, display devices that visualize and display fluids such as gas and liquid have been proposed. For example, in Embodiment 7 (paragraph number 0074) of Patent Document 1 below, there is an apparatus that displays a picture, a character, or the like by regularly translating a fluid as a vortex ring into an arbitrary space and selectively visualizing them. It is disclosed. Patent Document 2 below discloses an apparatus that forms an image of an arbitrary character or figure on the water surface using waves formed on the water surface.

  On the other hand, the inventor of the present application has already proposed a display device using a liquid in the following Non-Patent Document 1 from a viewpoint different from the above-mentioned Patent Documents 1 and 2. The techniques of Patent Documents 1 and 2 are mainly intended to display information such as characters and figures using a fluid, but the display device of Non-Patent Document 1 below displays a pattern. Yes, the flow formed on the liquid surface by heat convection of the liquid in the container is displayed as a pattern. Opportunities for humans to observe the state of the subject and gain awareness through perceptual experiences have a value different from linear understanding through the accumulation of formal knowledge of theories and laws. The inventor of the present application is the beginning of thinking about the profoundness of the world where people have gained new awareness from objects that they have not been able to grasp with the formal knowledge they have gained, Considering that it is possible to create an opportunity, the display device described in Non-Patent Document 1 below was developed.

  Actually, as a result of letting people experience the display device of Non-Patent Document 1, some viewers have a strong interest in delicate movements and shapes created by fluids, familiar thermal fluid phenomena and weather. Many people were associated with the system and biological cells, and the achievement of the initial objectives was confirmed. In addition, there were viewers who watched desperately, and we could consider the possibility of leading to a creative cognitive state due to arousal potential. On the other hand, as described above, the display device of Non-Patent Document 1 visualizes the flow appearing on the liquid surface by the thermal convection of the liquid and displays it as a pattern, and the viewer's reaction is displayed. Since the present invention is greatly influenced by the pattern, the inventor has obtained a view that it is preferable to be able to display more various patterns in order to further develop the display device.

  In addition, when changing the color of the pattern, the display device of Non-Patent Document 1 needs to be replaced with a liquid dyed in a desired color, which has been troublesome in changing the color.

  Further, the display device of Non-Patent Document 1 has a room for further improvement because it causes a thermal convection by heating a liquid, and therefore has a relatively slow reaction rate and high energy consumption.

  Accordingly, an object of the present invention is to provide a display device that can display various patterns using a fluid, can easily change the color of the pattern, and has a quick reaction speed and is suitable for energy saving. It is an object of the present invention to provide a display device unit provided with the display device unit and a decoration using the display device unit.

  As a result of intensive studies to solve the above problems, the present inventor has come up with the idea that all of the above problems can be solved by using gas and laser light. That is, the display device of Non-Patent Document 1 displays the flow that appears on the liquid surface due to the thermal convection of the liquid as a pattern, but the inventor of the present application pays attention to the flow generated inside the fluid, We thought that it would be possible to display a variety of patterns by visualizing the flow. In addition, when changing the color of the pattern, the display device of Non-Patent Document 1 needs to be replaced with a liquid dyed to a desired color, and the change of the color has been troublesome. Therefore, we thought that the color of the pattern could be easily changed by changing the color of the laser beam. And while achieving the improvement of reaction rate and energy saving at the same time, as a method to realize this, the gas flow is irradiated with a sheet-like laser to visualize the cross section of the gas flow and display it as a pattern In view of this, the present invention has been completed.

That is, the display device of the present invention includes a case having a translucent part that can visually recognize the internal space;
Gas supply means for supplying gas from the supply port to the internal space of the case;
An airflow generating means for generating an airflow in the gas supplied from the gas supply means to the internal space;
Laser irradiation means for irradiating the internal space with a sheet-like laser capable of visualizing the gas.

  According to the present invention, gas is supplied from the supply port to the internal space of the case by the gas supply means, and an air flow is generated in the gas by the air flow generation means, so that a gas flow is generated in the internal space of the case. In that state, when the sheet space laser is irradiated to the internal space by the laser irradiation means, the cross section of the air current is visualized. The visualized cross section of the airflow is displayed as a pattern that can be visually recognized through the translucent portion. Since the air flow varies depending on the position of the cross section, it is possible to display various patterns, and it is possible to easily change the color of the pattern simply by changing the color of the sheet-like laser.

  The airflow generating means is preferably a heating means for generating thermal convection in the internal space. According to this invention, a gas flow can be created in the internal space of the case by generating thermal convection by the heating means.

  The gas supply means preferably has a plurality of supply ports. According to this invention, the gas supplied from each supply port forms a flow independently, and a boundary line arises between each flow. When the sheet-like laser is irradiated in this state, the boundary line is visualized and displayed as a pattern. For example, it is possible to display a symmetric geometric pattern by arranging supply ports in a predetermined pattern.

  The air flow generation means is provided for each supply port, and it is preferable that the gas air flow supplied from each supply port can be controlled. According to the present invention, since the gas air flow supplied from each supply port can be controlled by each air flow generating means, the gas air flow from each supply port can be changed independently.

  The gas supply means preferably supplies gas by vaporizing a gas source by heating. According to this invention, the gas can be quickly supplied by using a gas source that is easily vaporized by heating, such as liquid paraffin or a smoke generating agent.

Further, the display device unit of the present invention comprises the display device and control means connected to the display device,
The control means includes a storage unit that stores a plurality of state patterns indicating states of airflow generated by the airflow generation means;
Output means for outputting the plurality of state patterns to a display device;

It is preferable that air flow control means for controlling the air flow generated by each air flow generating means in accordance with the sequence data received by the sequence data receiving means.

  According to this invention, since the state of the airflow can be changed over time by the control means, various patterns can be continuously displayed.

  The decorative tool, furniture, or joinery of the present invention includes the display device or the display device unit. According to the present invention, the display device and the display device unit can be used in various situations.

<Description of operation>
Hereinafter, the operation of the display device D of the present embodiment will be described. As a preparation stage, the gas source is stored in the storage unit 22 with the top plate 12, the frame 13 a, and the substrate 31 removed. In the present embodiment, gel-like liquid paraffin is used as a gas source. Since liquid paraffin is rapidly vaporized by heating, gas can be supplied quickly, which is preferable from the viewpoint of the reaction rate of the display device D and energy saving. Moreover, as a gas source, you may use the smoke generating agent which raise | generates a chemical reaction by heating and generates a fume. Examples of the smoke generating agent include those referred to as fog juice, smoke liquid, fog liquid, smoke fluid, and the like. Among these smoke generating agents, those which do not generate harmful substances such as carbon monoxide and are harmless to the human body are preferable. Furthermore, it is preferable that there is little odor, it is easy to remove deposits generated in the apparatus due to smoke generation, and the risk of fire is low. From these points of view, glycol-based fuming agents such as aqueous solutions mainly composed of low-toxic glycols such as propylene glycol (for example, fog juice containing about 45% glycol and about 55% water) are suitable. is there. Glycol-based smoke generators have low toxicity, low odor, and the deposits generated in the equipment due to smoke are water droplets that are easy to remove, reduce the risk of fire, and are treated as non-hazardous substances in the Fire Service Act. Therefore, no troublesome work is required at the time of use in public facilities, and it is very suitable as a gas source.

  After the gas source is set in the storage unit 22, the substrate 31 is set in a state where each heating means 24 is positioned so as to be arranged in each storage unit 22, and then the reflecting mirror 13 is placed on the side of the case body 11 The frame body 13a is set so that it may be located in the translucent part 11d, and the top plate 12 is mounted on it. Further, the laser unit U2 is disposed in the vicinity of the main unit U1, more specifically, below the reflecting mirror 13. The laser unit U2 is disposed below the projecting portion 11f of the case body 11, but the projecting portion 11f is formed of a transparent acrylic plate or the like having translucency, and the laser light irradiation path is There is no inhibition.

  Next, the substrate 31 is lowered using the elevating means 80, the heating means (nichrome wire) 24 is immersed in the gas source, and then the current is applied to the heating means 24 in the state where the substrate 31 is raised to turn off the gas source. Heat. Thereby, the gas source adhering to the heating means 24 is vaporized, and the gas is supplied from the supply port 21 to the internal space s1.

  FIG. 7 is an explanatory diagram for explaining thermal convection. The gas supplied from each supply port 21 forms a flow (thermal convection) independently by the airflow generation means 30 (heating means 24), and a boundary line is generated between the convections. That is, the gas from the supply port 21 first flows upward, and when it reaches the top plate 12, it spreads in the horizontal direction and collides with each other. The impinging convection changes the direction of the flow downward when the force is balanced, and a boundary is formed between the convections.

  In this state, a sheet-like laser r is emitted from the laser unit U2. As shown in FIG. 6, the sheet-like laser r irradiated from the laser irradiation unit 90a is reflected by the reflecting mirror 13 and irradiated in a direction crossing the internal space s1. Thereby, the cross section of the airflow (thermal convection in the present embodiment) is visualized. This visualized cross section is visible from the translucent part 12a and is displayed on the display device D as a pattern.

  The laser unit U2 can control the irradiation position in the internal space s1 by sliding the laser irradiation apparatus main body 90, and can display cross sections at various positions as patterns. For example, as shown in FIG. 8, when the laser irradiation apparatus main body 90 is positioned at the position p2 and the sheet-like laser r is irradiated to a position slightly (several mm) below the top plate 12, the boundary line of thermal convection stands out. When the pattern is displayed at the position p1 and irradiated near the top plate 12, a pattern spreading along the top plate 12 is displayed. When the pattern is positioned at position p3 and irradiated near the supply port 21, the supply port 21 The flow of the jetting gas is displayed as a pattern. Even by slightly changing the irradiation position, the appearance of the texture changes slightly, and various patterns can be displayed.

  Moreover, the color of a pattern can be changed only by changing the color of the sheet-like laser irradiated from the laser unit U2, and the pattern of various colors can be displayed easily.

  FIG. 9 is a diagram illustrating an example of a pattern (pattern at the position p2 in FIG. 8) displayed through the translucent part 12a. A plurality of supply ports 21 are provided in the display device D, and each forms thermal convection. Therefore, the boundary line of each thermal convection is visualized and displayed as a symmetric geometric pattern.

  FIGS. 10A to 10C are diagrams showing examples of patterns displayed when the state of the airflow from each supply port 21 is controlled by each airflow generation means 30. FIG. For the sake of explanation, the state of the airflow at each supply port 21 controlled by each airflow generating means 30 is shown in the lower left of each figure. In the present embodiment, since the air flow generating means 30 is realized by the heating means 24, the current application state of the heating means 24 is shown. As shown in FIG. 11, the arrangement state of the respective heating means 24a to 24s is represented by a pattern in which hexagonal cells are arranged in a simulated manner, and the heating means in which the current is OFF is represented by a frame-shaped cell. The heating means which is ON is represented by a solid cell. FIG. 10A is a diagram showing a display state when the currents of the heating means 24b, 24e, 24i, 24m, 24n, 24o, 24p, 24k, and 24f are turned on and the currents of the other heating means are turned off. FIG. 10B is a diagram showing a display state when the currents of the heating units 24a, 24h, 24q, 24s, 24l, 24c, and 24j are turned off and the currents of the other heating units are turned on. FIG. 10C is a diagram showing a display state when the currents of the heating units 24a, 24h, 24q, 24s, 24l, and 24c are turned on and the currents of the other heating units are turned off. Each has a different pattern. This is because the heat convection state of the gas supplied from the supply port 21 differs depending on the amount of heat of the heating means 24. In this way, various patterns can be displayed by independently controlling the airflow supplied from each supply port 21.

  FIG. 12 is a diagram illustrating an example of a display state when the airflow changing unit 50 is operated. In the present embodiment, the airflow changing means 50 is realized by raising and lowering the substrate 31 by the raising and lowering mechanism 80, and the pattern can be changed by the raising and lowering operation. FIG. 12A is a diagram showing a pattern displayed when the substrate 31 is raised and lowered instantaneously by a large operation. A pattern like a ripple is displayed on the display device D. FIG. 12B is a diagram showing a pattern displayed when the substrate 31 is lifted and lowered by the operation so as to continuously shake in small increments. On the display device D, a distorted pattern such as shaking is displayed. Thus, the pattern can be changed variously by using the airflow changing means 50.
