Description

  The present invention relates to the structure of a rearing case, and more particularly, to the structure of a rearing case with improved admirability without compromising safety and durability, and improved assemblability and waterproofness.

  Generally, in order to breed tropical fish and insects at homes and small-scale specialty stores, breeding cases which are small containers are used. Usually, the rearing case is formed of a transparent member such as a glass on the side so that the rearing object can be viewed, and is equipped with a temperature control means for setting the inside to a temperature condition suitable for rearing.

  Conventionally, a rod-like electric heater has been used as this temperature control means (see, for example, Patent Document 1). However, this electric heater has problems that it impairs the admirability and reduces the degree of freedom of the layout in the case. In addition, the durability is generally low, and particularly in the case of underwater use, when exposed to the atmosphere, there was a risk of abnormal overheating and ignition.

  In order to solve such a problem, a case for raising an organism having a bottom surface or one side surface formed of a plate-like heater has been proposed (see, for example, Patent Document 2). However, since this case for breeding animals uses a colored far-infrared radiator as a plate-like heater, there is a problem that the ornamental property is greatly impaired.

  Therefore, the inventors devised to construct the side of the breeding case from a transparent flat heater. The flat heater has a structure in which a transparent conductive film formed between two strip electrodes extending in parallel is sandwiched between two transparent substrates.

  However, when assembling the side surface of the case with such a flat heating body, although it is necessary to electrically connect a plurality of flat heating bodies, an operation of connecting adjacent strip electrodes to each other by soldering of conducting wires. There is a problem that it is very difficult to secure the waterproofness of the connection.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows the structure of a breeding case according to an embodiment of the present invention.

  This rearing case 1 has a rectangular bottom plate 3 which is open at the top and has two sides of two mutually separated rectangular members 2 which can be separated in the horizontal direction as side surfaces and which are connected to each other below. Is the bottom. In the breeding case 1, an environment tailored to the breeding object, for example, water and algae are created for tropical fish. In addition, the upper surface is covered by an easily removable plate-like lid member (not shown).

  In such a rearing case 1, at least two of the rectangular members 2 constituting the side surface are formed of the flat heating element 4. In the breeding case 1, all (four) of the rectangular members 2 are formed of the flat heating element 4.

  The structure of the flat heating element 4 is shown in FIGS. The flat heating element 4 includes two strip electrodes 5a and 5b provided along two opposing sides of the member 2, and a transparent conductive film 6 formed between the strip electrodes 5a and 5b. It comprises a transparent intermediate film 7 in which the strip electrodes 5a and 5b and the transparent conductive film 6 are embedded, and two transparent substrates 8 and 8 sandwiching the transparent intermediate film 7.

  Silver, chromium, aluminum, copper and gold, which are conductive metals, are used for the strip electrodes 5a and 5b. Examples of the transparent conductive film 6 include indium tin oxide, zinc oxide and tin oxide. For the transparent intermediate film 7, a transparent resin film made of ethylene vinyl acetate copolymer, polyvinyl butyral or the like is used. For the transparent substrate 8, resin (polycarbonate resin, acrylic resin, polyethylene terephthalate resin, etc.) can be used in addition to glass.

  Then, at one end of one of the two strip electrodes 5a and 5b (in this example, the strip electrode 5a), a connection electrode 9 for electrically connecting the two members 2 formed of the flat heating element 4 is fixed. It is done. As shown in FIGS. 3 and 4, the connection electrode 9 is a rectangular metal plate bent at a right angle at the central portion, and a strip shape so that the front end portion 10 is exposed to the outside of the transparent substrate 8. It is soldered on the electrode 5a. In the examples shown in FIGS. 3 and 4, the bent portion 11 of the connection electrode 9 is fixed parallel to the extending direction of the strip electrode 5a, but may be perpendicular. On the other hand, one end of the other strip electrode 5 b is exposed to the outside of the member 2 through the notch 12 at the corner of the transparent substrate 8.

  In the flat heating body 4, a transparent conductive film 6 is formed on almost the entire surface of one transparent base material 8 by a sputtering method or a vacuum evaporation method, and a paste form containing a conductive metal on the transparent conductive film 6 The composition of the invention is applied and thermally cured to form strip electrodes 5a and 5b, and the connection electrode 9 is soldered to one end of the strip electrode 5a, and the transparent conductive film 6 and the strip electrodes 5a and 5b are transparent intermediate films The other transparent base material 8 having the notch 12 is attached to the adjacent corner portion from the top covered with 7, and finally the resin 12 (epoxy resin etc.) is filled and formed in the notch 12 on the connection electrode 9 side. It is manufactured by doing.

  When using the breeding case 1, as shown in FIG. 1, the strip electrodes 5a and 5b of the flat heating element 4 are connected to the power supply 14 disposed outside the case via an electric cord (not shown) or the like. Connect by 15.

  A method of assembling such a side of the rearing case 1 will be described below based on FIGS.

  First, as shown in FIG. 5, with respect to the tip portion 10 of the connection electrode 9 fixed to the strip electrode 5a of one member 2A of the two members 2A and 2B adjacent to each other on the side surface of the breeding case 1 The exposed end portions of the strip electrodes 5b of the other member 2B are made to approach and face each other.

  Next, as shown in FIG. 6, one end portion of the strip electrode 5b of the other member 2B is brought into contact with the tip end portion 10 of the connection electrode 9 of one member 2A and soldered. This soldering operation is performed from the side corresponding to the outside of the breeding case 1.

  Finally, as shown in FIG. 7, the resin 13 burys and shapes the tip portion 10 of the connection electrode 9 of the soldered member 2A in the notch 12 of the other member 2B and the strip electrode 5b of the member 2B. Do. The resin 13 ensures waterproofness of the electrical connection portion between the two members 2A and 2B.
