DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circulating water softening device which takes out bath water in a bath tub to make it soft and returns it to the bath tub again to produce a hot spring effect.

[0002]

2. Description of the Related Art Conventionally, many people wish that a home bath should be like a hot spring, and bath salts having an effect that is good for the skin have been often used. In addition, the ion exchange resin exchanges magnesium ions and calcium ions in the water with sodium ions to reduce the hardness of the water and soften the water, which has the effect of giving the skin a slippery feeling. It is well known.
For this reason, this ion exchange resin has been used as a water-pass type water softener which can easily soften the bath water in the bathtub by ion exchange by being attached to a faucet in the bathroom.

[0003]

However, in the case of such a water-pass type water softener for performing ion exchange by passing water, contact between the ion-exchange resin and water is caused by fluctuations in water pressure due to the twist of the faucet. It is difficult to make it uniform, and as a result, the softening effect of water tends to vary, and the softening effect may be insufficient.

[0004] Further, in this water-pass type water softener, there is no operation to make water once softened into the bathtub with insufficient softening even if it is desired to be softened further.

The present invention has been made in consideration of the above-described circumstances, and has as its object to provide a circulating water softening device that circulates bath water in a bath tub to ensure soft water.

[0006]

According to a first aspect of the present invention, there is provided a circulating water softening device, comprising: a water intake section for taking bath water in a bathtub; a pump for circulating the bath water taken from the water intake section; And a softening part that makes the water soft by replacement.

[0007] The circulating water softener according to claim 2 is claim 1.
Wherein the softening portion has an ion exchange resin for making the bath water soft.

[0008] The circulating water softener according to claim 3 is claim 1.
Wherein a filter for preventing dust in the bathtub from being sucked is installed in the water intake section.

The operation of the circulating water softener according to claim 1 will be described below. The pump circulates the bath water taken from the water intake section that takes in the bath water in the bath tub, and the softening section softens the bath water by ion exchange, and returns the bath water to the bath tub again.

Therefore, by operating the pump as necessary and circulating the bath water that has entered the bathtub in an insufficiently softened state, the softening is performed until a satisfactory slippery feeling is obtained without variation in water pressure. The treatment can be applied to the bath water. As a result, the foaming of the soap is improved in accordance with the slippery feeling, and the bather can realize a comfortable bathing like a hot spring.

The operation of the circulating water softener according to claim 2 will be described below. The present invention has the same function as the first embodiment. However, the present invention is configured such that the softening portion has an ion exchange resin that makes bath water soft water. Therefore, the ion-exchange resin ion-exchanges magnesium ions and calcium ions in the bath water circulated by the pump with sodium ions to make the water soft, and the softened bath water is returned to the bath tub again.

The operation of the circulating water softener according to claim 3 will be described below. The present invention has the same function as the first embodiment. However, the present invention is configured such that a filter for preventing suction of dust in the bathtub is installed in the water intake section.
For this reason, not only is the softening treatment applied to the bath water, but the filter removes the dirt in the bath tub, so that the dirt does not enter the pump and the softening part, and a more comfortable bath like a hot spring is provided. Bathers will be able to do so.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of a circulating water softener according to the present invention is shown in FIGS. 1 and 2, and the present embodiment will be described with reference to these drawings.

The circulating water softening device 10 installed next to the bathtub 32 includes a water intake section 12 for taking in bathwater in the bathtub 32,
Pump 1 for circulating bath water taken from water intake section 12
6, a softening section 18 for softening the bath water by ion exchange, and a discharge hose 20 for returning the softened bath water to the bathtub 32. And these water intake sections 12,
The pump 16 and the softening unit 18 are connected by a pipe 14 so that bath water is sent in this order, and a part of the water intake unit 12 and a part of the discharge hose 20 for supplying and draining the bath water are connected to a bathtub. 32.

Further, a filter (not shown) for preventing the suction of dust in the bathtub 32 is arranged in the water intake section 12 of the circulating water softener 10, and this filter removes coarse dust such as hair in the bath water. ing.

Here, in the tank 34 forming the softening portion 18, an ion exchange resin P for exchanging magnesium ions and calcium ions with sodium ions and softening bath water to make soft water is stored.

More specifically, as shown in FIG.
The granular ion-exchange resin P is arranged near the lower part in the cylindrical tank 34 of FIG. 8, and the upper part in the tank 34 is a space S. Caps 36 and 38, which are water supply / drain ports having strainers 36A and 38A, respectively, are installed in the upper and lower portions of the tank 34. The pipes 14 and the discharge hose 20 are connected to the caps 36 and 38, respectively. ing.

That is, although it is necessary to reduce the water flow resistance in the tank 34 to improve the flow of the bath water, the ion exchange resin P has a high water flow resistance. Has the disadvantage of becoming too large. Furthermore, the water flow resistance is reduced by making the ion exchange resin P in the tank 34 dance rather than stopping.

For this reason, the filling amount of the ion exchange resin P is set to 50 to 60% of the capacity of the apparatus which is the capacity of the tank 34, and the water flow in the tank 34 is set to an up-flow system in which bath water flows upward from below. .

As described above, the bath water taken from the bathtub 32 by the water intake section 12 according to the predetermined output of the pump 16 passes through the pump 16 and is guided to the ion-exchange resin P in the softening section 18 so that the bath water is removed. The magnesium ions and calcium ions in the water are exchanged for sodium ions and returned to the bathtub 32 again through the discharge hose 20.

The operation of the circulating water softener 10 according to the present embodiment will be described below. The pump 16 circulates the bath water taken from the water intake section 12 for taking the bath water in the bathtub 32, and the softening section 18 having the ion exchange resin P turns the bathwater into soft water by ion exchange. Is returned to.

Therefore, the pump 16 is operated as necessary to circulate the bath water which has entered the bath tub 32 in a state of insufficient softening, and the bath water is always supplied to the ion exchange resin P in the softening section 18 at a constant pressure. You can pass. For this reason, this ion exchange resin P ion-exchanges magnesium ions and calcium ions in the bath water with sodium ions to make soft water,
The softened bath water is returned to the bath tub 32 again. At this time, since the bath water always passes through the ion exchange resin P in the softening portion 18 at a constant pressure, there is no variation in water pressure and the like, and the ion exchange resin is always fixed. The effect will be obtained.

As described above, the softening treatment can be performed on the bath water until a satisfactory smoothness is obtained. Further, the foaming of the soap is improved in accordance with the smoothness, and the bath is taken in the bathtub 32. Bathers will have a pleasant bathing feeling like a hot spring.

Further, in the present embodiment, since a filter for preventing dust in the bathtub 32 from being sucked is installed in the water intake section 12, not only the softening treatment is applied to the bath water,
This filter removes the dust in the bathtub 32, so that the dust does not enter the pump 16 and the softening portion 18, and the bather can realize a more comfortable bathing like a hot spring.

In the above-described embodiment, the ion exchange resin P is used for the softening portion 18. However, it is needless to say that another material capable of ion exchange may be used. Further, in the above embodiment, the granular ion exchange resin P is used for the softening portion 18, but a ball-like or thread-like ion exchange resin P may be used.
