A cord 12 (not shown) is connected to a socket 42 inside the top lid via a connecting fitting 13 fixed to the top of the outer surface of the top lid. In this case, the sterilizing lamp 41 and the socket 42 are located approximately concentrically within the upper part 2C of the cylinder 2, and therefore are also approximately similar to the cartridge 31 for drinking water purification installed within the lower part 2b of the core. They are located concentrically. The germicidal lamp 41 in this embodiment is a lamp that emits ultraviolet light of about 6 watts.

Further, a flange 20 is formed on the upper inner surface of the upper part 2a of the cylinder 2, a support body 14 is fixed to the flange, and a waterproof seal 60 is provided at the contact portion between the support body and the flange.
is applied. A transparent cover plate 15 made of quartz glass, which covers the germicidal lamp 41 and the socket 42 and insulates them from drinking water, is supported at the upper end of the support, and is transparent to the ultraviolet rays emitted by the germicidal lamp. A waterproof seal 61 is applied to the contact portion between the transparent cover plate and the support body 14.

A ring-shaped receiving member having a U-shaped cross section is fixed approximately concentrically to the upper surface of the dividing plate 5 of the tube 2, and the receiving member has the following features:
A cylindrical member made of transparent glass that is approximately concentric with the cylinder 2 and the cartridge 31, with a predetermined distance W from the inner surface of the core portion, and surrounding the transparent cover plate 15 with a predetermined distance W2. 22 is fixed,

The ultraviolet rays emitted by the tube do not pass through, and together with the outer tube 2, the ultraviolet rays are prevented from harming the human body.

In this way, the outer surface of the transparent cover plate 15 and the cylindrical member 22
The inner surface forms a narrow annular sterilizing channel 45 for sterilizing drinking water around the sterilizing lamp 41, and the upper end thereof serves as a water overflow port 45a, with an interval W2. That is, the width of the sterilizing channel is designed to be such that the drinking water flowing therethrough can be sterilized reliably and instantaneously by the action of the sterilizing lamp 41.

Further, the outer surface of the cylindrical member 22 and the inner surface of the tube 2 have an upper flow path 46 with a predetermined width W1 that guides the drinking water flowing through the sterilization flow path 45 to the outside.
, and a cartridge 31 located further below.
The outer surface of the tube 2 and the inner surface of the tube 2 are connected to the upper flow channel through a plurality of water holes 5a of the dividing plate 5, and a lower flow channel 47 having a predetermined width W

The width W of the lower flow path 47 and the dimensions of the water holes 5a and 5c of the dividing plate 5 are such that the purified and sterilized water led from the sterilization flow path 45 to the upper flow path can be adjusted by turning the faucet 52a of the water faucet 52. It is set so that an appropriate amount always flows out in proportion to the condition.

In addition, the cylinder 2 has a ventilation hole 4 located at a high position above the upper end of the upper flow path 46, that is, the upper end of the sterilization flow path 4.5.
When the water purifier 1 is not in use, the cock 51a of the switching valve 51 can be appropriately operated to drain the water remaining in the water purifier to the inlet passage 7a of the base 7 and the air hole 9. This is provided to enable discharge from the downwardly extending portion 53 of the faucet 52 via the switching valve. Note that the ventilation hole 49
Another function is to serve as a guide for knowing the appropriate amount of drinking water to be discharged from the faucet 52.

Function The present invention is constructed as described above, and its function will be explained below. In Figures 1 to 3, as well as Figures 5 and 6, when using the water purifier 1, the germicidal lamp 4 is
1 is turned on, the cock 51a of the switching valve 51 is operated as appropriate to the water purifier side, and then the tap 52a of the water faucet 52 is turned in the direction of opening.Drinking water flows through the introduction path 7a of the base 7. and flows into the cartridge 31. The drinking water is first filtered through the foamed acrylic resin bottom plate 33 of the cartridge to remove iron, fine particles, etc., and flows into the first alumina ceramic granule layer 34 until it reaches the first partition plate 37.

Drinking water whose flow path is blocked by the partition plate 37 is supplied to the faucet 5.
The alumina-based ceramic granule layer 34 is
When the water pressure is high, the water flows in a zigzag manner and concentrates in the water passage hole 37a at the peripheral edge of the partition plate 37 as shown by the arrow in FIG. Inflow. In this case, the drinking water remains in the alumina-based ceramic granule layer 34 under high pressure and for a short period of time, so the granule layer acts more effectively on the drinking water, reducing the amount of ammonia contained in the drinking water. Completely adsorbs nitrogen, etc. and deodorizes it.

The same effect as described above is carried out sequentially in the next calcium-based ceramic granule layer 35 and the next another calcium-based ceramic granule layer 36, and the ceramic granule layer 35 ensures calcium, sodium, etc. in the drinking water flowing through it. The next ceramic granule layer 36 completely absorbs and removes the limescale odor of the drinking water flowing through it.

In this way, the drinking water flowing in a zigzag pattern as shown by a series of arrows through the water passage holes 37a, 38a, 139a of the partition plates 37, 38. It is further filtered by the acrylic resin upper plate 32 to completely remove iron, fine particles, etc., and flows into the next sterilization channel 45 through the water passage hole 5C in the center of the rear dividing plate 5.

Because the drinking water that has flowed into the sterilizing channel flows around the sterilizing lamp 41, along and near the sterilizing lamp 41 due to the structure of the sterilizing channel, the ultraviolet rays emitted by the sterilizing lamp completely pass through it. The water metal body flowing through the sterilization flow path is acted on in a radial manner through a transparent cover plate 15 made of quartz glass to reliably and instantaneously sterilize bacteria in the water.

The water purified and sterilized in this way overflows from the overflow port 45a of the sterilization channel into the outer outlet channel 48, which has a pair of water holes 5a and 5b provided diametrically opposite each other. Since the dividing plate 5 divides the water into an upper passage 46 and a lower passage 47, purified and sterilized water flowing through the outflow passage 48 flows through the upper passage and passes through the pair of water holes in the dividing plate. While flowing through the lower flow path and flowing out from the outflow lower b to the outside, the water level stops near the position in the upper flow path, and the purified and sterilized water flows out from the outflow lower b while maintaining a constant amount. do.

In this case, a waterproof gasket 6 is provided between the lower end of the cartridge 31 for purification and the upper surface of the base 7, and a similar waterproof gasket 9 is provided between the upper end of the cartridge and the lower surface of the dividing plate 5. As a result, purified and sterilized water flowing through the outlet passage 48 does not mix with unsterilized water. In addition, a waterproof seal 61 is applied to the contact area between the transparent cover plate 15 and the support body 14, and a waterproof seal 60 is applied to the contact area between the support body and the flange 20 of the tube 2, so that drinking water can be dispensed. Even if the drinking water exceeds 4.
It will not infiltrate into the area.

In addition, if too much drinking water is dispensed, the excess drinking water is discharged to the outside through the vent hole 49, so that the excessive drinking water can be immediately detected and the situation can be appropriately adjusted.

In addition, when water is removed from the sterilization channel 45 and the cartridge 31 when the water purifier 1 is not in use, the cock 51a of the switching valve 51 is used.
By appropriately operating the sterilization channel to the water drain side, water in the sterilization channel and the cartridge is drained through the introduction channel 7a of the base 7 and the switching valve by the action of the vent hole 490 provided in the cylinder 2 to the extension part of the faucet 52. 53 to 7 are discharged to the outside.

Note that alumina ceramic granules 3 used in this example
4. Calcium-based ceramic materials 34, 35 are instant-acting, so they not only purify drinking water immediately, but also maintain their purifying power for a relatively long period of time. For example, for a family of 4 to 5 people, 1.8 yen per day is used for drinking water, tea, coffee, etc.
t to 3. It is economical to obtain Ot by replacing the cartridge 31 only about once every six months.

In addition, the water purifier 1 compactly combines the water purification system 3 and the electrical system 4 for sterilization to form a relatively small size, so it is easy to install on a water faucet in a general household and can save a lot of space in the kitchen. It won't get in the way of cooking as it won't get in the way. In addition, the bluish light from the sterilizing lamp 41 gives a sense of beauty and cleanliness to the viewer through the transparent cover plate 15 made of quartz glass, the cylindrical member 22 made of transparent glass, and the transparent tube 2 made of acrylic resin. It not only serves as a gift but also becomes part of the interior of the kitchen.

Effect Since the present invention is constructed and operates as described above, a transparent cover plate through which ultraviolet rays can pass is provided around the germicidal lamp, and a narrow annular cover plate through which drinking water flows is provided around the transparent cover plate. By providing a drinking water channel and allowing the drinking water to flow through the channel, there is an effect that sterilization can be performed reliably and instantaneously. Furthermore, since the water purification system and the electrical system are completely separated, it is possible to prevent water leakage to the electrical system or electrical leakage to the water purification system, and it is possible to obtain a water purifier that is highly safe and easy to maintain. Another object of the present invention is to provide a water purification system of a water purifier with a purification layer made of ceramic materials having various components and properties, and to divide the purification layer into partitions with different beat constants for each type. At least one water passage hole is provided in each suitable place, and the water passage holes are arranged alternately on the left and right for each partition plate, so that drinking water flows through the purification layer in a zigzag pattern over a long period of time. In addition, it is possible to effectively and completely purify drinking water, and the ceramic material can be used effectively without waste. Another purpose is that it combines the water purification system and electrical system of the water purifier, so it is multifunctional and compact, making it easy to install in the kitchen of a general household and not getting in the way of cooking. There are effects that can be achieved. Another object is that the sterilizing lamp emitted in the electric system of the water purifier is visible from the outside through the transparent exterior, which gives the water purifier an aesthetic appearance and a sense of cleanliness.
