Description

  The present invention relates to a water purifier or a water purifier that reforms tap water distributed to each household into water for cooking by purifying the water in the water source into clean water, drinking it and purifying it into safe water.

  Water quality standards have been established for tap water that people can drink with confidence until they exit the faucet at home. In addition, in order to maintain the safety of tap water, in addition to restricting forest protection and land use in the water source area, strict water quality management is added to monitor and regulate pollution prevention, and more sophisticated and complex water treatment is applied. Yes. In general, spring water, groundwater, and upstream river water that flows out from the forest area are of good quality and are stable in quantity, so they can be used as water sources in small-scale waterworks.

  However, since these water sources have limited water volume, they cannot meet the demand of large-scale cities, and have to rely on river water and lagoon water with a large flow rate. In the upper and middle basins of rivers and Kakinuma water, it is possible to take in a large amount of water with relatively good water quality and low human pollution, but when a large amount of rain falls at once, clay that makes the water turbid Colloids, phytoplankton and natural pollutants that inhabit the water flow in, so after separating them from the raw water in the sedimentation pond, they pass through a filtration tank filled with fine sand and dissolved in iron, manganese and dissolved in the raw water Water purification treatment is performed to remove pollutants and further sterilize with chlorine.

  However, the water quality of the purified water is lowered while flowing through the water pipe. The problem of water quality deterioration is caused by water pipes, and management of water pipes is regarded as important. For example, the problem of the brownish water flowing out is that a metal or other material is eluted from the inner wall of the water pipe (especially cast iron rust outflow). Measures have been taken to provide curved piping in buildings due to the cause of stagnation of the water flowing through water pipes and the local increase in the concentration of dissolved metal.

  Even if such water purification measures were taken, a very small amount of suspended matter and manganese leaked from the water purification plant and accumulated in the water pipe for a long time used a large amount of water for fire extinguishing activities in summer and fire. In some cases, it was peeled off at a high pipe flow velocity and discharged from the faucet. In addition, chlorine sterilization treatment is required to ensure safety from pathogenic microorganisms, but there is also a problem that the chlorine effect is easily lost in water pipes of a wide distribution system.

  Many types of water purifiers have been developed and used for the purpose of drinking water that has been purified from raw water after being purified from raw water, and that is safe, yet clean. A water purifier allows tap water to pass through activated carbon stored in a filter or an activated carbon filter such as that disclosed in Japanese Patent Application Laid-Open No. 2003-144821, so that off-flavor components and trace amounts of organic substances contained in tap water can be removed. It utilizes the effect of adsorbing and removing innumerable fine pores of activated carbon.

  However, when activated carbon adsorbs organic substances that serve as a food for microorganisms, activated carbon becomes a hotbed of microorganisms, propagates various germs, and flows into running tap water, resulting in an unsanitary vessel. In addition to this, water purifiers with only hollow fiber membranes have been developed, but there is a problem that the odor of mold and mold cannot be removed. For this reason, cartridge-type water purifiers that combine activated carbon and hollow fiber membranes have been developed and used a lot. This water purifier is a hollow fiber bundled with hollow fibers with a diameter of 200 to 300 μm that has micropores on the wall surface, which suppresses the proliferation of bacteria by silver ions coated with silver on the surface of activated carbon, purifies water with antibacterial activated carbon It consists of a two-stage purification process mechanism that removes fine particles such as residual chlorine and iron rust by flowing water through the membrane and prevents outflow of various bacteria.

Further, Japanese Patent Application Laid-Open No. 11-277051 discloses a water purifier using activated carbon and a ceramic honeycomb filter, and Japanese Patent Application Laid-Open No. 2003-71459 discloses a water purification material using a ceramic material such as “magnetic ceramic water treatment material”. Technology has also been developed.
Interest in delicious water has further increased, and bottled water has been widely sold under the name of “100 selections of famous water” or “mineral water”.

  Many of the water purifiers developed to date as described above have a water purification effect in ordinary households that pass a small amount of water sent through water pipes, but in an emergency where a large amount of water is used Households, restaurants or company employee cafeterias, etc., because the contact time between water and activated carbon or hollow fiber membranes is short and the water purification action disappears at an early stage due to the passage of a large amount of water. There was a problem that had to be replaced frequently. In addition, every time I made dishes such as simmered foods and soups using purified water, there were many occasions where the taste changed little by little. Furthermore, if tofu is made with water having a pH value of 7.0 or more, there is a problem that the product cannot be made unless more coagulant is added than usual, and the water has a pH value of 3.0 or less. There was a problem that tofu was sour.

  The present inventors have solved these problems and provide a purifier that can be used for either a faucet direct connection type or a stand-alone stationary type, and that does not lose its water purification function and does not change the properties of water. As a result of repeated experiments and examinations for the purpose, the subtle changes in the taste of the dish depend on the wide pH value of the purified water. It was discovered that by convection vigorously with a diversion pipe, the pH value of the weakly acidic zone remained, and the flavor of the soup stock and ingredients were sufficiently extracted to create a mellow taste dish. It was also found that by stabilizing the pH value of water in a weakly acidic zone, anyone can reliably make tofu with a certain amount of coagulant, regardless of the season, without relying on the intuition of experts. The present invention is configured based on this finding.

  The gist of the present invention that achieves the above-described object is that a water supply straight passage that penetrates from the water supply side to the water distribution side is provided in the water supply path of the tap water supply pipe or water supply, and the water supply side of the outer peripheral surface One or two or more ceramic diversion flow pipes with a water supply slant passage communicating with the water distribution side of the water supply straight hole passage are overlaid and held, and the tap water or water purifier for tap water is held. It is.

  Weakly acidic zone while removing tap water for eating and drinking flowing through the water pipe and passing through the water purification organ for eating and drinking of the present invention while removing tap water for eating and drinking from the household tap. While maintaining the PH value, it is purifying as much as the spring water in the forest area. The purifying effect does not disappear even in restaurants that use large amounts of water, company cafeterias, etc., and can create dishes with a mild taste.

Hereinafter, the water purifier for cooking of the present invention for improving the quality of drinking tap water will be described in detail with reference to the drawings.
FIG. 1 shows an embodiment of the present invention. A faucet directly connected water pipe attached to a faucet (not shown) of a water pipe or a water pipe just before the faucet is connected to a faucet (not shown). A sectional view in the direction of the water supply path is shown with a stand-alone stationary type water purifier attached.
In FIG. 1, 1 is a water supply pipe (or water supply device). The water supply side (upper side in the drawing) of the water supply pipe 1 is directly connected to the faucet. That is, the water supply pipe 1 is provided in a structure for sending tap water discharged from the faucet through the water supply path 2 to the water distribution side (lower side in the drawing).

  3 is a porous ceramic diversion flow pipe that is used along one water supply path 2 of the water supply pipe 1 or two or more if necessary. A water supply straight hole passage 4 penetrating through the water supply is provided in the shaft core portion, and a large number of water supply oblique hole passages 5 are inclined and communicated from the water distribution side of the outer peripheral surface to the water distribution side of the water supply direct hole passage 4 from the outer peripheral surface to the inner peripheral surface. The outer diameter of the water supply pipe 1 is such that the tap water flowing through the water supply path 2 of the water supply pipe 1 easily flows from the outer peripheral surface to the water supply oblique hole path 5 and easily enters and exits the water supply pipe 1. Is provided in a smaller loose insertion shape.

  In the present invention, when the ceramic diversion pipe 3 is loosely inserted and held at a predetermined position of the water supply pipe 1, a locking projection may be provided on the peripheral wall surface of the position of the water supply pipe 1 on the water supply hole path side. Or you may carry out cross-sectional shaping | molding of the water supply path 2 of the part of the water supply pipe 1 in the bulging latching shape. Further, the shape of the water supply oblique hole path 5 of the ceramic diversion flow pipe 3 is not limited to the straight parallel hole path as shown in FIG. 1, but the inscribed line direction of the water supply straight hole path 4 as shown in FIG. A large number of water supply oblique holes 5 oriented in the direction, a large number of water supply oblique holes 5 oriented in a crossing direction at a phase height as shown in FIG. 2B, or a mixed water supply oblique hole path or other water supply obliques. It may be a hole.

  Furthermore, in order to make it easy for the water flowing through the water supply path 2 to smoothly flow into the water supply straight hole path 4 or the water supply oblique hole path 5 of the ceramic water diversion pipe 3, the two ceramic water diversion pipes 3 overlapped in FIG. As shown in the cross-sectional view, the upper end portion around the water supply path 2 may be formed into an arcuate protrusion shape. That is, the ceramic diversion flow pipe 3 according to the present invention once diverts the water flowing through the water supply path 2 of the water supply pipe 1 into the water supply straight hole path 4 and the water supply oblique hole path 5 and then again the water supply straight hole path 4 and the water supply oblique line. It is provided in a structure in which the mixture is violently mixed at the junction of the holes 5.

The cooking water purifier of the present invention configured as described above is an independent water pipe connected to a water pipe via a faucet directly connected water purifier generally used at home or a branch faucet often used in a restaurant or the like. Used in the same way as a stationary water purifier with a structure.
However, the water purifier for cooking of the present invention divides a large amount of tap water flowing through the water supply path 2 of the water supply pipe 1 into the water supply straight path 4 and the water supply slanted path 5 and further supplies the water. In order to distribute water while making strong water disturbance and fine water particles due to violent clash and convection at the point, and minute gaps in the ceramic material, the odor components and trace organic substances remaining in the tap water are trapped in the ceramic porous chamber and further Purified water. Purified water that has passed through the water purifier for cooking of the present invention is transformed into clean water from drinking tap water or safe water, and exhibits a weakly acidic zone with a stable PH value, and the taste of food and ingredients Pull out.

  The reason for this cannot be clarified, but according to the inventor's guess, the tap water that has flowed slowly through the water pipe is diverted when passing through the ceramic diversion pipe 3, and then the strong impact that is mixed. The structure of water changes to fine water particles due to the disturbing action of the water, gradually releasing components such as iron and carbon stored in the voids of the ceramic material due to the disturbing action, and water instead of the original structure and properties The reaction of wrapping or decomposing a small amount of off-flavor components or fine organic substances in tap water caused the behavior to improve the water quality, resulting in purified water with a pH value in a weakly acidic zone. I guess.

Next, an embodiment of the present invention will be described.
A water purifier for cooking which has a faucet of a water pipe installed in each household, a water supply pipe 1 having an outer diameter of 15 mm and a water supply path 2 of 13 mm as shown in FIG. Was directly connected and the tap water was purified. The ceramic diversion flow pipe 3 used at that time is provided with a water supply straight passage 4 having an inner diameter of 3.3 mm in a ceramic block having an outer diameter of 10 mm and a length of 100 mm, and further a water supply oblique hole having a hole diameter of 2 mm. Two of the channels 5 that were provided with holes dispersed at equal intervals were used by stacking two.
At this time, the flow rates of the tap water and the well water that flowed through the water supply path 2 of the water supply pipe 1 were tested at 8.5 L / min.

As a result of measuring the PH value of the water at this time, the tap water of the raw water flowing out from the faucet was 7.2, the well water was 5.9, and the tap water passed through a cartridge type water purifier combining activated carbon and a hollow fiber membrane. Although the water was 7.2 and the well water was 5.9, the purified water of the tap water and the well water that passed through the water purifier for cooking of the present invention was 6.5.
In this way, raw water with a slightly higher or lower pH value can be used to make the most delicious dishes by fully extracting the flavor of the ingredients among the cooks by passing through the water purifier for cooking of the present invention. In a weakly acidic zone (PH value of 6.4 to 6.8 is most preferred).
In addition, when tofu is made with water that passes through the water purifier for cooking, it is possible for non-experts to ensure stable cooking only by using a certain amount of coagulant throughout the year.

  If you use the water purifier for cooking of the present invention, it is good to drink, clean and use with clean water, just like spring water, groundwater, upstream river water flowing out from the forest area, good for beauty Since water can be made freely, there is a high possibility that it will be used while global environmental issues are being questioned.

In one Example of this invention, sectional drawing of the water purification pipe | tube directly connected to a faucet is shown. The upper surface perspective view of another water supply oblique channel in the ceramic diversion flow pipe 3 is shown. Another embodiment of the ceramic diversion pipe 3 is shown in a sectional view in the direction of water supply.
