Abstract

PURPOSE:To prevent completely propagation of bacteria even when the titled water purifier is stopped by forming a water passage which sterilies in a vertically zigzag line at the inside of the main body of the purifier for drinking water, packing a purifying material at the lower part of the water passage part, and furnishing a sterilizer in the upper space part of the main body. CONSTITUTION:An untreated water inflow port 3 is provided to one upper side of the main body 1 of a water purifier for drinking water, and a purified water outflow port 4 to the other upper side. The first partition plates 9a, 9b, and 9c leading from a position slightly higher than the inflow and outflow ports 3 and 4 to the lower midway position and the second partition plates 7a and 7b leading from the position slightly lower than the inflow and outflow ports 3 and 4 to the lower bottom part of the main body are alternately furnished in the main body to form a water passage part sterilying in a vertically zigzag line. Besides, a purifying material 11 is packed from the position slightly lower than the inflow and outflow ports 3 and 4 to the lower bottom part, and a sterilizer 15 which is operated when the water discharge is stopped is provided in the upper space part in the main body 1. Consequently, chlorine can be removed from city water, and propagation of bacterial when the water purifier is stopped can be completely prevented.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a drinking water purifier that purifies tap water, etc., and in particular removes chlorine contained in tap water etc. for sterilization purposes and improves the operation of the water purifier. This invention relates to a drinking water purifier that prevents the proliferation of bacteria within the water purifier.

(Prior art and its problems) In recent years, there has been a shortage of drinking water sources in the suburbs of cities, so even water sources that could not meet water quality conditions up until now have to be used as drinking water sources. In order to use these water sources as drinking water, it has become necessary to purify and sterilize them more than ever before, and it has become necessary to mix chlorine with a gP of 1.

Tap water mixed with a large amount of chlorine in this way only increases the chlorine odor, making it unsuitable for drinking as water for enjoying luxury items such as coffee.For this reason, activated carbon is being used in households and restaurants recently. An increasing number of places are installing water purifiers that dechlorinate water using water.

However, although such purifiers can dechlorinate water and provide good-tasting water, if the water purifier is stopped for a while, the dechlorinated tap water will lose its sterilizing effect. Many bacteria breed inside the water purifier, causing the water to become unsuitable for drinking and spoil. Therefore, such water may cause back stains or cause 91% damage.
It can also cause food poisoning.

(Means for Solving the Problems) The present invention has been made in view of the above points, and consists of an interior of a drinking water purifier main body, which has a purified water inlet on one side of the upper side and a purified water outlet on the other side. A first partition plate extending from a position slightly higher than the inflow outlet to a position halfway down, and a second partition plate extending from a position lower than the inflow outlet to a lower bottom part of the main body are alternately arranged. Forming a waterway that travels up and down,
This drinking water purifier is characterized in that a purifying material is filled from a position slightly lower than the inlet/outlet to the lower bottom, and a sterilizing device that operates when the water is stopped is provided in the upper space of the main body.

(Example) An example of the drinking water purifier of the present invention will be specifically described below based on the drawings.

Figures 1 and 2 are longitudinal cross-sectional views of the water purifier of the present invention. 6 1 is connected to a faucet 2 of a water supply or the like on one side, and leaks water (processed water).
The housing has an inlet 3 through which the processing liquid flows in, and an outlet 4 through which the processing liquid is discharged on the other side. The housing 1 consists of a septic tank 5 and a lid 6 that is hinged to a threaded portion 5a at the top of the septic tank 5,
It is sealed to form a container.

The inside of the septic tank 5 is connected from the inner bottom 5b to the inlet/outlet 3.
2. The conversion plate 7mb is erected at a position slightly below 4 and protrudes vertically to a position slightly higher than the position of the inlet/outlet 3.4 (processing liquid water level 8). Y□L t= wH
'Name h9□. .

In each of the six divided areas 10a-f, which are divided into sections 10a to 10r and form bent and traveled water flow passages, activated carbon and zeolite are respectively placed between a position slightly lower than the inlet and outlet to the bottom. A purifying material 11 selected from animal and plant proteins such as degreased wool fibers is filled, and the upper surface thereof is lightly pressed and fixed by a wire mesh 12.

A water reservoir layer 13 consisting of leaked water and treated water is formed above the wire mesh 12 in the upper part of each zone 10a to 10a.

An ozone generator 15 suspended from the lid 6 is attached to the air space 14 above the water reservoir layer 13, and the ozone generator 15 generates ozone and irradiates ultraviolet rays to the water reservoir layer 13. Sterilize.

Since the purified water that has passed through the layer of purification material 11 has chlorine removed, it is easy for bacteria to grow, so the purified water is constantly flowing. While the water filter is in use (i.e., when in use), the LA bacteria will not propagate, but when the flow stops (i.e., when it is not in use), fil will propagate inside the water purifier, and once the bacteria have propagated, they will not grow unless they are sterilized. Continue to breed. In vf, bacteria that have entered the purification material 11 are difficult to sterilize because the flow of water in the purification material 11M tends to stagnate, and this becomes an ideal breeding place for bacteria, so bacteria do not invade the purification material 11 layer. Thus, in the present invention, the water reservoir layer 13 is formed as a sterilizing layer.

The water reservoir layer 13 is sterilized by dissolving ozone generated by the ozone generator 15 from the treatment liquid water surface 8 to dissolve the ozone in the treatment liquid, and at the same time irradiate ultraviolet rays to perform sterilization in a short time. It is configured as follows.

The above-mentioned ozone generator is electrically connected to stop the operation of the ozone generator 15 when the pulp 16 is opened, since it is difficult for 2i bacteria to invade and reproduce when purified water flows out due to the opening of the pulp 16. Connect and control.

In addition, if there is a risk that ozone dissolved in the water tank will flow out as a thick ozone-containing water by opening the pulp 16, as shown in FIG. The upper part of the area 10a
a and septic tank 5I! By partitioning the lt section with a transparent plate 17 such as an acrylic resin plate, it is possible to prevent ozone from entering and reduce the ozone concentration, while allowing only ultraviolet rays to be irradiated.

(Effects of the Invention) As detailed above in the Examples and the like, the drinking water purifier of the present invention can purify tap water by dechlorinating it,
When used as water for tasting luxury items such as fuhi, there is no chlorine odor and the delicious taste can be enjoyed.6 It also completely prevents the growth of bacteria in the water purifier when it is not operating. Even if the water purifier is activated and the purified water is taken out after the water purifier has been out of use for a relatively long period of time, the purified water can be immediately drunk.

Even if well water or natural water is used as leakage water, if the sterilizer is constantly activated, 21 bacteria can be prevented from entering the purification layer and multiplying, making it an extremely useful beverage. It is a water purifier.

As described above, the present invention is capable of achieving excellent effects that have never been seen before, and thus makes a very large contribution to this field.
