Embodiment Construction

[0134] figure 1 It is a simplified diagram showing a structure in which a water treatment device 1 according to an embodiment of the present invention is incorporated in a large pool 2 such as a swimming pool or a public bath.

[0135] In the pool 2, there is a main circulation passage 20 for circulating the water W stored in the pool. A circulation pump 23 , a filter 21 for filtering sand, and a heat exchanger 22 for heating water W are arranged on the main circulation passage 20 . The water W of the pool 2 circulates in the main circulation path 20 as indicated by the dot-dash arrow.

[0136] The water treatment device 1, as indicated by the solid line arrow, has water branched into water from the branch point J1 on the downstream side of the filter 21 of the main circulation passage 20, and returns to the water at the branch point J2 on the downstream side of the heat exchanger 22. Processing lane 10.

[0137] On the water treatment channel 10, a regulating valve B1 for ...

Abstract

The present invention is directed to a new water treatment device comprising an electrolytic tank to put water in, an electrode provided in the electrolytic tank, a water treating path for pouring water in a pool and returning to the pool the water in the electrolytic tank, a residual chlorine sensor for measuring the residual chlorine concentration of water, and control means for controlling the energization of the electrode on the basis of the measured value by the residual chlorine sensor, and capable of simply and efficiently sterilizing water stored in pools.

Description

technical field [0001] The present invention relates to a new water treatment device capable of sterilizing water stored in various pools ranging from large pools such as swimming pools and public baths to water supply pools placed on roofs of buildings and small pools such as bathtubs used in general households. Background technique [0002] For example, for indoor and outdoor swimming pools or public baths, etc., in order to maintain its water quality, bleaching powder, sodium hypochlorite (NaClO) and the like must be regularly added thereto for disinfection. [0003] However, there is a problem in the conventional disinfection treatment that workers in the facility must manually perform this operation outside business hours (such as in the morning or late at night). Moreover, since bleaching powder and sodium hypochlorite are irritating, care must be taken during operation. [0004] In addition, since the bleaching powder is usually made into powder or tablet form, it ta...
