FIG. 1 is a sectional view showing an example in which the present invention is implemented in a water purifier. In the figure, 1 shows the water purifier as a whole, 2 is a water inlet, 3 is a water outlet, 4 is a lid, 5 is an internal board, 6 and 6' are light emitting diodes, 7 is a filter, and 8 is a water purifier. It is an external board. Such a water purifier 1 can be seen as a type of small tank. The outer shape of this tank may be cylindrical or prismatic. The lid 4 is circular if the outer shape of the tank is cylindrical, and square if the outer shape of the tank is prismatic.

なお、発光ダイオード６，６′には適当な透光性
保護被膜を施してある。 A substrate 5 with a light emitting diode 6 attached to the back of the lid 4
is fixed, and the light emitting diode 6 illuminates the inlet side (primary side) from the filter 7. The external board 8 has a ring shape if the tank outer shape is cylindrical, and a square ring shape if the tank outer shape is prismatic. The light emitting diode 6' attached to the inside of the external board 8 is located on the outlet side (secondary side) of the filter 7.
irradiate. In this embodiment, at least the portion of the tank facing the light emitting diode 6' needs to be transparent. When only the light emitting diode 6 is provided, the tank does not need to be transparent.
Note that the light emitting diodes 6, 6' are coated with a suitable light-transmitting protective coating.
本例では、発光ダイオード６，６′として、レ
ーザ発振により、例えば800nｍ程度の波長の近
赤外線を発光するレーザダイオードが使用され
る。 In this example, as the light emitting diodes 6 and 6', laser diodes that emit near-infrared rays with a wavelength of about 800 nm by laser oscillation are used.
発光ダイオードは個々の大きさが小さいので、
多数使用の場合でも、光源の占有空間を小さくす
ることができる。 Since the individual size of light emitting diodes is small,
Even when a large number of light sources are used, the space occupied by the light sources can be reduced.
本発明は、発光ダイオードが発する可視光線や
赤外線でも菌の増殖を防止する作用がある点に着
目してなされたものである。 The present invention was made based on the fact that visible light and infrared rays emitted by light emitting diodes have the effect of preventing the growth of bacteria.
周知のように、レーザ光は指向性がよく、適宜
の光学系により所要部分をスポツト的に照射し
て、光エネルギーを高密度に集中することができ
る。また、パルス発振の場合、各レーザダイオー
ドの光出力は、例えば40〜50ｍＷ程度になる。 As is well known, laser light has good directivity and can be used to irradiate a desired area spot-on using an appropriate optical system to concentrate light energy with high density. Further, in the case of pulse oscillation, the optical output of each laser diode is, for example, about 40 to 50 mW.
菌がこのスポツト照射を受けた場合、菌細胞内
の吸収物質による吸光で温度が上昇し、蛋白質の
凝固などの熱損傷が発生して、増殖バランスがく
ずれる。 When bacteria are exposed to this spot irradiation, the temperature rises due to light absorption by absorbing substances within the bacterial cells, causing thermal damage such as coagulation of proteins and disrupting the growth balance.
菌の増殖周期は、例えは、最も短い種類の一つ
である大腸菌でも30分程度であることが知られて
おり、上述のスポツト照射のためには、比較的長
時間が許容されることになる。このため、前述の
ように比較的小出力の半導体レーザを用いても、
照射部分の菌の増殖を抑えることができる。可視
光を発光する半導体レーザを使用する場合も同様
である。 It is known that the growth cycle of bacteria, even for Escherichia coli, which is one of the shortest types, is about 30 minutes, and a relatively long period of time is acceptable for the above-mentioned spot irradiation. Become. Therefore, even if a relatively low output semiconductor laser is used as mentioned above,
It is possible to suppress the growth of bacteria in the irradiated area. The same applies when using a semiconductor laser that emits visible light.
これにより、光源を小形かつ長寿命として、比
較的小形のタンクに簡単に取り付けることができ
て、衛生小形タンクを廉価に構成することができ
る。 Thereby, the light source can be made small and have a long life, and can be easily attached to a relatively small tank, so that a small sanitary tank can be constructed at a low cost.
なお、周知のパルス発振の場合には、各発光ダ
イオードの出力を大きくできるので、発光ダイオ
ードの数を適宜に少なくしうる。 Note that in the case of well-known pulse oscillation, the output of each light emitting diode can be increased, so the number of light emitting diodes can be appropriately reduced.

10 is a partition plate, 11 is a power supply device, 12 is a power cord, and 13 is a contact lens. In this embodiment, the inside of the water container 1 is irradiated from below, and therefore the partition plate 10 needs to be light-transmissive. The power supply device 11 includes a transformer, a rectifier, and the like, but the power source may be a battery type (or rechargeable type).
