JPH1110145A - Soft water instrument with ejector - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a soft water instrument, inexpensive and of good handling properties by the single handle changeover operation for changing over four processes consisting of the introduction of tap water, the introduction of soft water, the ion exchange resin backflow cleaning and the suction generation of table salt water in a soft water instrument for passing tap water into an ion exchange resin container and preparing soft water. SOLUTION: A water pipe 5 is connected with an anion exchange resin container, and a table water container 4 is connected with the head of a cation ion exchange resin container 1 through a table water duct 4-1. Also a shower head 8 is connected with a discharge outlet of the cation exchange resin container 1 through a discharge duct 8-2. A changeover handle 27 is provided on the head of the anion ion exchange resin container 1, and tap water is sprayed out of the shower head 8 when the handle 17 is set on 'tap water' indicated on a displayed plate 26. In the case the handle 27 is turned by 180 deg. and set on 'soft water', soft water is sprayed out of the shower head 8. Similarly backwashing and regenerating can be carried out by operating the handle 27.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small and simple water softener used in a beauty salon, a sushi restaurant, and a general household.

[0002]

2. Description of the Related Art In an apparatus for softening hard water, hard water is passed through a container filled with a cation exchange resin to soften the water. In this case, in proportion to the capacity of the collected softened water, ions such as Ca ⁺⁺ and Mg ⁺⁺ are attached to the cation exchange resin, and the water softening ability is reduced to be inactive. When a saline solution is passed through the cation exchange resin whose water softening ability has been lowered, all ions such as Ca ⁺⁺ and Mg ⁺⁺ attached to the cation exchange resin are replaced with Na ions ⁺ and the water softening ability is regenerated. In the conventional water softening apparatus, an apparatus for industrially collecting a large amount of softened water by the above-described method is used. These were large-scale devices that were all automatically operated to collect soft water, regenerate the cation exchange resin, etc., using air pressure, solenoid valves, motors and the like. However, in recent years, there has been an increasing need for tap water to be further softened to use the effect of soft water in beauty salons, sushi restaurants and other restaurants, coffee shops, general households, etc., and a small, simple and inexpensive water softener is required. It is supposed to be. In beauty salons, the need for using soft water is increasing because soft water improves the foaming of soap when washing face and hair as an effect of soft water, and the water can be washed effectively.
It has also been empirically demonstrated that the use of soft water is effective for the skin of people with atopic dermatitis. In sushi restaurants, it has been empirically demonstrated that cooking rice with soft water makes it possible to cook plump and delicious rice, and that vinegar is effective, and the need for soft water is increasing. In a coffee shop, if you put coffee in soft water, you can get the original taste of coffee beans, and in the case of tea, it was reddish,
It has been empirically proved that delicious tea of a beautiful color can be served, and the need for using soft water is also increasing. Also, in general households, the need for soft water is increasing because soft water is suitable for cooking rice, putting tea, washing face, washing hair, and the like.

[0003]

The utility of water softeners in each of the above-mentioned fields has been demonstrated, and the spread rate is small despite the high needs. It turns out there is no. Therefore, an object of the present invention is to provide a simple and inexpensive water softener that can be installed under a wash basin, a sink, or the like, and can be switched by one handle.

[0004]

Means for Solving the Problems The water softener with an ejector of the present invention is installed under a wash basin, a sink, etc. of a beauty salon, a sushi restaurant, a restaurant, a coffee shop, a general household, etc., and directly connected to a water pipe. From the tap water faucet and soft water faucet provided above the wash basin, sink, etc. from the water softener with the ejector,
Tap water and soft water are collected. The water softener with ejector of the present invention installed in this way is rotated by one handle,
It has a four-stage switching valve for switching the following four steps. (1) When it is not necessary to use soft water, in order to prolong the life of the cation exchange resin, tap water is directly passed through without passing through the cation exchange resin. It has a switching valve function that leads to the tap water faucet. (2) It has a switching valve function of passing tap water through a cation exchange resin to soften it and guide it to a soft water faucet. (3) Switching valve for flowing tap water from the opposite direction to the cation exchange resin, that is, flowing tap water from below the cation exchange resin, washing the ion exchange resin from below to loosen it, and guiding it to the drain. Has functions. (Hereinafter referred to as backwashing.) (4) Tap water is flowed downward from above the cation exchange resin, and by utilizing the water pressure of the tap water, salt water is guided from a separately provided saline solution container to perform cation exchange. It has a switching valve function to regenerate the resin and guide the waste water to the drain port.

[0005]

According to the present invention, a water softener with an ejector is installed under a wash basin, a sink, etc., and is directly connected to a water pipe, and a tap water faucet provided above the wash basin, a sink, etc. from the water softener with the ejector, It is plumbed to the soft water faucet. The water softener with ejector of the present invention installed in this way is rotated by one handle,
Has a four-stage switching valve (1) When collecting tap water, adjust the handle of the four-stage switching valve of this water softener to the display position of tap water, open and close the tap water faucet, and use tap water. Collect a quantity. (2) When collecting soft water, set the handle of the four-stage switching valve of this water softener to the display position of soft water, open and close the soft water faucet, and collect a required amount of soft water. (3) Tap water is flowed from below the cation exchange resin, and the ion exchange resin is washed so as to be loosened from below, that is, in the case of backwashing, the handle of the four-stage switching valve of the water softener is displayed in the backwashing display position. According to the water pressure of the tap water, the water flows upward from below the cation exchange resin through a conduit in the cation exchange resin, is discharged from a drain port, and is backwashed. After backwashing for a certain period of time, the handle of the four-stage switching valve of the water softener is set to the display position of tap water, and the backwash is completed. (4) When regenerating the cation exchange resin, when the handle of the four-stage switching valve of the water softener is set to the display position of regeneration, tap water flows downward from above the cation exchange resin, and at the same time, the saline solution container. The saline solution is sucked in and drained from the drain port, and at this time, a regeneration process is performed. After performing the regeneration process for a certain period of time, the handle of the four-stage switching valve of the water softener is set to the display position of tap water, and the regeneration process is completed.
