Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improvement of a sterilizing water purifying apparatus mainly for sterilizing tap drinking water with a filter and a sterilizing lamp.

[Conventional technology]

2. Description of the Related Art Conventionally, a water purifying apparatus that first filters drinking water with a filter and then sterilizes it with an ultraviolet germicidal lamp has been widely known. Among these, for example, as a relatively large-scale water purifying device that can purify a large amount of drinking water, a drinking water supply unit as shown in JP-B-58-40145, in which a filter and a sterilizer are separately configured in a flow path. It has been known. Also, as a relatively small water purification device that can be directly attached to the tap of a water supply, etc., a cylindrical sterilizing tank is concentrically arranged inside a cylindrical hollow filter, as shown in Japanese Utility Model Publication No. 50-24063. Various sterilizing water purification devices are known.

[Issues to be solved by the device]

As described above, after filtering drinking water with a filter, a water purification means for sterilizing with a sterilizing lamp is already known, but of course, these filters and sterilizing lamps are both long-term. The service life will be exhausted after extended use, so it is necessary to replace it with a new one. When looking at the repair and replacement work of such a filter and sterilizing lamp, the water purifying device as shown in the above-mentioned JP-B-58-40145 has a filter and a sterilizer, a generator and a pump, and a flow path. Since each of them is a relatively large equipment unit that is individually arranged through, for example, when the life of the sterilization lamp in the sterilizer expires after a usage period of about 5 months, replace only the sterilization lamp. Often neglects to replace the filter. Of course, in this way, repairing and exchanging the germicidal lamp and the filter individually at different times requires repairing and exchanging work each time it is found that one of the appliances loses its effect. However, it has a management problem that it is complicated.

On the other hand, the latter one in which the filter and the germicidal lamp are concentrically arranged in one container, as shown in Japanese Utility Model Publication No. 50-24063, has an advantage that the device itself can be constructed in a small size. The container and the germicidal lamp have a concentric arrangement relationship, but are not configured to have an integral connection relationship. Therefore, when the life of the germicidal lamp has expired, only the germicidal lamp is replaced as in the above case, and if the filter is also replaced at that time, the entire device must be disassembled in a large scale, so it is necessary for an amateur. Is decomposed,
There has been a problem that the work of parts replacement and assembly is too complicated. Therefore, this device has a structural defect that it is difficult to replace the filter because it is difficult to replace the filter even if the sterilizing lamp can be easily replaced, and an appropriate water purification action cannot be performed. Was.

[Means for Solving the Problems]

In order to solve the above-mentioned problems of the conventional sterilizing and water purifying apparatus, the present invention incorporates a filter and a sterilizer into one cartridge, attaches this cartridge to a substrate, and sterilizes it by using it for a long time. When the life of the lamp expires, you can replace the filter at the same time by replacing the cartridge,
Moreover, the purpose of the present invention is to provide a sterilizing water purifier that can be easily replaced by an amateur such as a housewife.

The present invention is, as a specific means therefor, a sterilizing water purification apparatus for drinking water which is used by being connected to a tap of a water supply, in which a filtration chamber and a sterilization chamber are provided as one cartridge on a substrate having a lid cover. It is configured to be installed, the filtration chamber having a filter inside and the sterilization chamber having a sterilization lamp inside are provided in a pair of parallel pipes for filtration chamber and pipe for sterilization chamber, respectively. By fitting and fixing both ends of the pipes to a pair of pipe holders, respectively, the pipes are integrally connected and held in parallel, and the filtration chamber and the sterilization chamber are fluidly connected to the outside of one pipe holder. The pipe is connected to the other pipe holder, and a water inlet connection pipe into the filtration chamber and a water outlet connection pipe from the sterilization chamber are provided outside the other pipe holder to form the cartridge, and the cartridge is installed in the sterilization chamber. Kicking it mounted so that detachable from the upper substrate provided with a feeding device of the sterilizing lamp is characterized in.
