Description

technical field [0001] The present invention relates to a filter box and its installation structure, and more specifically, to an external box for accommodating a filter for purifying water supplied in a refrigerator, a structure for installing the above-mentioned box in an external space, and utilizing the A method of sterilizing the piping downstream of the filter by installing the filter box and piping structure. Background technique [0002] At present, refrigerators have gone beyond the function of simply storing food, and also have the function of purifying water and supplying purified water in the form of cold water and ice cubes. Therefore, a refrigerator includes: a water purification filter; a water tank for storing purified water; an ice maker for freezing the stored water to make ice cubes of an appropriate size; for supplying purified water, cold water, ice cubes, etc. water intake department. Currently, there are various types of refrigerators that realize su...

Problems solved by technology

Therefore, it is difficult to use a refrigerator having the above-mentioned additional functions as a built-in home appliance.

[0006] For example, in order to maintain the filter that needs to be replaced in units of several months, in the prior art, the work is performed by approaching the upper part of the refrigerator and replacing the filter installed on the upper part of the refrigerator, while the refrigerator installed in the form of a built-in appliance Such an assignment would become very difficult in the case of

For this reason, the filter is installed in the front so that the user can easily access the filter, which will occupy a part of the storage space inside the refrigerator.

[0007] In addition, in the case of pipes installed inside the refrigerator for supplying and moving water, when contamination occurs in the pipes and bacteria multiply, it is necessary to carry out work such as disinfection or sterilization, or to replace the pipes. Some require access to the rear of the refrigerator to achieve

For refrigerators installed in a built-in manner, such operations are inevitably very cumbersome
