Description

  The present invention is an improvement of a light emitting decorative device, more specifically, a fantastic visual effect due to the brightness of light and the behavior of bubbles can be further enhanced, the shape can be easily diversified, and the structure is also very simple. The present invention relates to a light emitting decorative instrument.

  As is well known, lighting equipment such as light-emitting objects and chandeliers that are excellent in visual effects are frequently used to create a luxurious or original atmosphere in a room.

  And as such a luminescent decorative instrument, a light source is arranged at the lower part of a transparent single tube filled with a working liquid inside a transparent single tube material, and further, bubbles are generated by utilizing the heat generated by the light source. An instrument that creates a fantastic atmosphere using the behavior of rising bubbles and the visual effect of light scattering through the bubbles has been known (see, for example, Patent Document 1).

  However, in the above-mentioned conventional decorative device, only the bubbles are generated, the working fluid inside the tube is not changed at all, and the number of detached bubbles generated when the heat generation of the light source is in a low temperature range. However, there was a part lacking in the fun of the production effect.

  In addition, since the shape of the single tube type is limited to linear, zigzag, corrugated, etc., it is difficult to produce in a complicated three-dimensional shape. It was very inconvenient because many single tubes had to be fixed side by side.

  On the other hand, conventionally, a technique of filling an annular pipe connected to a pump with a working fluid and generating bubbles by the pump and simultaneously circulating the inside of the annular pipe by pumping the working fluid and the bubbles is also known. (For example, refer to Patent Document 2).

  However, when the above-described conventional technology is applied to a light-emitting decorative device, the structure becomes very complicated, so it is very difficult to reduce the size of the decorative device and reduce the manufacturing cost. .

In addition, when pump pumping is used, the movement of hydraulic fluid and bubbles will be unsatisfactory due to an artificial impression, and in addition, the rotation sound of the motor running inside the pump will become an unpleasant noise that is fantastic. There was a risk of damaging the atmosphere.

  Hereinafter, the configuration of the present embodiment will be described in detail. First, in the present embodiment, the annular pipe 1 enclosing the working fluid 11 is communicated with the heat receiving pipe section 12 and the heat radiating pipe section 13 made of stainless steel, and the lifting pipe sections 14a and 14b made of transparent glass pipes. (See FIGS. 1 and 2).

  The heat receiving pipe portion 12 of the annular pipe 1 is provided with a steam expansion chamber E bulging upward, and the steam contracting chamber S bulging upward is also formed in the heat radiating pipe portion 13 of the annular pipe 1.

  Next, water was used as the working fluid 11 contained in the annular pipe 1, and the water was sealed in the annular pipe 1 under reduced pressure so as to be in a low boiling point state.

  Further, an incandescent bulb is disposed as a light source L for emitting the working fluid 11 at the lower portion of the heat receiving tube portion 12 of the annular pipe 1, and the heat generated by the incandescent bulb can be used as the heating mechanism H. .

  With the configuration described above, when the heat receiving pipe portion 12 is heated, the bubbles B released from the steam expansion chamber E rise up the riser pipe portion 14a, and at the same time, the hydraulic fluid 11 is brought into the annular pipe 1 by the rising force. Therefore, in addition to the behavior of the bubble B floating in the ascending pipe or the bubble C descending in the downcomer, the flow of the working fluid 11 and the shimmering light that changes in a complicated and subtle manner due to the flow are more fantastic. A beautiful atmosphere can be created.

  In addition, the generation of bubbles B is promoted by the steam expansion chamber E provided in the heat receiving pipe portion 12 of the annular pipe 1 and the number of bubbles in the ascending pipe 14a is also increased, so that the occurrence of bubbles caused by light scattering is sufficient. You can enjoy it.

  The fluorescent dye mixed with the hydraulic fluid 11 contains not only thioflavin T but also blue-white diamino skelben, blue-green uranin, yellow-orange eosin, red rhodamine B, and other colored fluorescent substances. It may be.

  Further, the steam contraction chamber S provided in the heat radiating pipe portion 13 of the annular pipe 1 serves as a decompression tank, so that the internal pressure of the annular pipe 1 increases excessively during heating, and the annular pipe 1 does not have to be ruptured. It is very safe.

  And since the structure which consists of the annular pipe 1 and the light source L is very simple, it is also easy to aim at size reduction of an instrument and reduction of manufacturing cost.

  In addition, since the fatty acid salt which is a surfactant is added to the hydraulic fluid 11 contained in the annular pipe 1, the foaming property is improved and the generation of bubbles B is promoted, and the effect of the bubble pump is dramatically improved. Can be improved.

  Further, in this embodiment, the boiling stone F is provided inside the steam expansion chamber E, so that bumping is suppressed and steam generation at the start of the apparatus occurs without resistance. Especially when the apparatus size is reduced, it is instantaneous. As a result, a bubble pump action occurred and heat transfer started very effectively.

  In addition, as a substitute for the boiling stone F, a lump or the like formed by rounding an ultracapillary tube can be used.

  In addition, ethyl alcohol having a boiling point lower than that of water can be used as the working fluid 11 sealed in the annular pipe 1, thereby lowering the generation temperature of detached bubbles, so that the light source L has a low temperature range and a low temperature difference. Even when only the above heating can be performed, the working fluid 11 can be circulated.
