Description

[Detailed description of the invention] (Field of industrial application) The present invention provides a closing structure for the upper end surface of a cylinder that separates each gap in a water purifier, etc. The present invention relates to the disclosure of a new lid structure in which a flange portion is provided and grooves are provided on the lower surface of the periphery of the lid body.

(Prior Art) In the past, it was difficult to attach and detach the lid, which caused manufacturing difficulties, and it was also inconvenient to clean.

In addition, in order to facilitate attachment and detachment, grooves are provided on the lower surface of the peripheral edge of the lid of the water purifier, and the upper edge of the cylindrical body of the water purifier and the lid fit together. Since the holding force depends only on the frictional force acting on the upper edge of the cylinder, a tightening member was required to press the peripheral edge of the lid against the upper edge of the cylinder to resist internal pressure. Therefore, it is also difficult to apply the pressing force uniformly to the peripheral edge of the lid to improve watertightness.

(Purpose and structure of this invention) The present invention was specially devised in view of the inconveniences in the conventional precedent, and one of its main purposes is to increase the water pressure resistance of the sealing surface and improve water purification. This was designed to prevent leakage caused by water leakage.

Also, one of the other main purposes of this invention is to
The reason for this is that the lid can be attached and detached freely, making it convenient for manufacturing and management.

Therefore, in order to achieve appropriate and purposeful effects on these characteristics, the present invention has a structure in which a cylindrical filter filled with activated carbon is fitted into the inner cylinder, and the inner cylinder is filled with activated carbon. An outer cylinder is fitted around the cylindrical filter, an ion exchange resin is loaded into the gap between the outer cylinder and the inner cylinder, and the trapped treated water is introduced from the outer peripheral surface of the cylindrical filter into the inner gap and filled with ions. In a water purifier in which the exchange resin is supplied from the upper surface and captured and supplied below the resin, the upper edges of the inner cylinder and the outer cylinder are formed into brim-like flanges, and a separately prepared disc-shaped lid is attached to the water purifier. The flange portion is placed at a point where it fits into a concave groove provided around the lower surface of the periphery, and considerable design changes are planned in accordance with the gist of this configuration.

(Embodiment) Hereinafter, a typical embodiment of the present invention shown in the drawings will be described in detail. Reference numeral 1 denotes an outer cylinder, into which an inner cylinder 2 is fitted, and the outer cylinder 1 and the inner cylinder are connected to each other. An ion exchange resin 3 is filled in the gap with the cylinder 2, and a cylindrical filter 11 filled with activated carbon or the like is fitted inside the inner cylinder 2, and the treated water is initially supplied to the supply port in the base plate 10. 8, inner cylinder 2 and cylindrical filter 11
The structure is such that the permeated water is passed through the filter and guided inward by conducting through the gap between the filter and the ion exchange resin, and the final permeated water is stored in the central pipe 9 through the conduction. In line with the flange portions 1a and 2a obtained by folding the upper ends of the outer cylinder 1 and the inner cylinder 2 outward by 90 degrees, the outer cylinder 1 and the inner cylinder 2 are fitted around the lower surface of the periphery of the disc-shaped lids 4 and 5, which are prepared separately. The flanges 1a and 2a are fitted into the grooves formed, and the lids 4 and 5 are fitted through the central pipe 9, respectively, and the lid 5 is tightened by the nut 7 screwed into the pipe. The lid body 4 is tightened only by the cap screwed onto the pipe 9.

The lower part of the water purifier is a base plate 10 provided with holes for regulating the passage of treated water.

The present invention has the characteristic structure described above, in particular, a cylindrical filter 11 filled with activated carbon is fitted into a middle cylinder 2, an outer cylinder 1 is fitted around the middle cylinder 2, and the outer cylinder 1 and The gap with the inner cylinder 2 is filled with an ion exchange resin 3, and the captured treated water is introduced from the outer peripheral surface of the cylindrical filter 11 into the inner gap and is supplied from the upper surface of the filled ion effect resin 3 and permeated therein. In a water purifier that captures and supplies resin from below, the upper edges of the inner cylinder 2 and outer cylinder 1 are connected to a brim-like flange portion 1a,
2a and disc-shaped lids 4 and 5 prepared separately.
The flange portion 1 is inserted into the concave groove provided on the lower surface of the periphery of the flange portion 1.
By fitting parts a and 2a, the deficiencies of the prior art described above can be effectively corrected, and the following specific effects are expected.

(Effect of the invention) That is, in the present invention, the upper end edges of the inner and outer cylinders 1 and 2 are made into flange parts 1a and 2a, and the bottoms of the grooves in the lids 4 and 5 are formed by the repulsive force due to the bending of the flange parts. It is in pressure contact with the flange portion, and the repulsive force of the flange portion increases the contact force between the outer peripheral edge of the flange portion and the concave groove of the lid body, thereby improving watertightness and water pressure resistance. be.

In addition, the present invention has the above-mentioned configuration, which makes it easy to attach and remove the lids 4 and 5, making it easy to manufacture.
This eliminates the need for a separate sealant.

Furthermore, the present invention is convenient for cleaning and managing the water purifier, and is also convenient for draining water.

Furthermore, in the present invention, the upper end edges of the inner and outer cylinders 1 and 2 are reinforced with flanges 1a and 2a, which eliminates distortion of the cylinders and facilitates repeated attachment and detachment of the lid. This is what I did.

As mentioned above, the present invention relates to the disclosure of a lid structure for a water purifier that is novel and has sufficient effectiveness.
