Abstract

PURPOSE:To rationally subject water to be treated to dechlorination, pH control, sterilization and deodorizing treatments by successively arranging a calcium sulfite bed, a magnesium hydroxide bed, a coral sand bed and an activated carbon bed in a water purifying cartridge. CONSTITUTION:When an operating lever 38 is revolved, tap water rises through the gap between an outer cylinder 41 and a water purifying cartridge 42 from the first jet orifice 13d in a whirling state and floods to flow in the water purifying cartridge 42. Then, the tap water passes through a fiber filter material 44a to reach a magnesium hydroxide bed 45 to receive pH control and subsequently passes through a calcium sulfite bed 46 to remove residual chlorine while treated water is sterilized in a coral sand bed 47 and deodorized by an activated carbon bed 48 to be led out from a purified water outflow port 51 through a fiber filter material 44b. By this method, the dechlorination, pH control, sterilization and deodorizing of water to be treated can be performed rationally.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a water purifier for further purifying drinking water, such as well water, tap water, etc.

(Conventional 0) Technology) The above type of water purifier, which has been commonly used in the past, has a water-permeable fiber filtration layer on the top and side, an activated carbon layer on the bottom, and a purification member. The water to be treated is purified by flowing it down from the -F section of the water purifier and filtering it through the purification member. However, in this water purifier, suspended matter contained in tap water adheres to the surface of the activated carbon during water purification and causes clogging, so the activity of the activated carbon tends to decrease in the first phase. Furthermore, since the water to be treated is caused to flow down inside the purification layer, the water to be treated tends to form a flow path with low resistance in the purification layer, and therefore the utilization efficiency of the purification layer is low. Therefore, in order to improve these drawbacks, a purification member with an activated carbon layer on the upper side and a water-permeable fiber filtration layer on the lower side is placed inside the water purifier, and the water to be treated is sent to the lower part of the water purifier. A water purifier has also been developed in which purified water is introduced from the L section of the water purifier.

(Problem to be solved by the invention) However, in such water purifiers, the purification layer is constantly immersed in the water to be treated, which makes it unhygienic as bacteria tends to breed in the purification layer. There was a problem with this. Further, such water purifiers also have a problem in that the adsorption capacity of the activated carbon layer decreases relatively quickly due to suspended matter in the water to be treated.

The present invention has been made in view of the above problems faced by the prior art, and its purpose is to maintain the adsorption capacity of the activated carbon layer even if suspended matter is contained in the water to be treated such as tap water. To provide a water purifier capable of preventing or suppressing the propagation of bacteria without premature water degradation, and capable of removing chlorine contained in water to be treated.

(Means for Solving the Problems and Achieving the Objects) According to the present invention, the above-mentioned problems are solved by providing a purification member for purifying the water to be treated, and a purification unit disposed on the downstream side of the purification member. A water purifier comprising a valve device for controlling the inflow of water to be treated and an operation member for controlling the operation of the valve device, wherein the purifying member is configured as a water purifying cartridge forming an inner cylinder. The cartridge for water purification has a calcium sulfite layer, a magnesium hydroxide layer, a coral sand layer, and an activated carbon layer therein. The problem is solved by a water purifier characterized in that the water to be treated, which is controlled by the operation of an operating member, rises through the gap between the inner and outer cylinders, overflows, and then flows down into the inner cylinder to be purified. At the same time, the above objectives are achieved.

The above-mentioned problem also includes a purification member that purifies the water to be treated, a valve device that is arranged upstream of the purification member and that controls the inflow of the water to be treated into the purification member, and a valve device that controls the operation of the valve device. In the water purifier, the purifying member is configured as a water purifying cartridge consisting of an inner cylinder and an outer cylinder, and the inner cylinder is concentrically arranged within the outer cylinder with a predetermined gap. A layer selected from a calcium sulfite layer, a magnesium hydroxide layer, a coral sand layer, and an activated carbon layer is placed in the gap between the inner and outer cylinders, and each layer other than this layer is placed in the gap between the inner and outer cylinders. The water to be treated, which is placed in the inner cylinder and controlled by the operation of the operating member, rises through the gap between the inner and outer cylinders, overflows, and then flows down the inside of the cylinder to be purified. This problem is solved by a water purifier characterized by the following, and the above objects are achieved.

(Function) In the water purifier according to the present invention configured as described above, if the valve device is operated by the operating member, the water to be treated can be caused to flow into the purification member side. If configured as a three-way valve and provided with a bypass, the water to be treated can be discharged to the outside without flowing into the purification member. When the operating member is operated so that the water to be treated flows into the purification member, the water to be treated flows into the water purification cartridge which is the purification member. The inflowing water to be treated is treated with a calcium sulfite layer built into the water purification car 1 to the tank, where chlorine contained in the water to be treated is removed.
The pH of the water to be treated is adjusted in the magnesium hydroxide layer, the water to be treated is sterilized in the coral sand layer, and the water to be treated is deodorized and purified in the activated carbon layer.

Further, the purifying member has a water purification car 1 to ridge ζ structure consisting of an inner cylinder and an outer cylinder, and the inner cylinder is arranged concentrically within the outer cylinder with a predetermined gap, and the inner cylinder is arranged concentrically within the outer cylinder with a predetermined gap. C) any one layer selected from a sulfite lucium layer, a hydroxide macnesillum layer, a coral sand layer, and an activated carbon layer is arranged in the inner cylinder, and the other layers are arranged in the inner cylinder, In the same manner as above, the water to be treated can be dechlorinated, [) It is possible to increase the amount of agent and therefore without increasing throughput.

In addition, in the purifier according to the present invention, the water to be treated flows into the 17th part between the inner and outer cylinders, ascends through the gap between the outer and outer cylinders, and
Since the water overflows and flows into the inner cylinder, flows down the inner cylinder and is led to the outside, it is necessary to leave a gap between the inner and outer cylinders, or bacteria may grow in the gap. Hygiene problems can be avoided by forming a difficult treatment agent layer.
