Description

  The present invention relates to a water purifier mainly used for filtering tap water at home.

  2. Description of the Related Art Conventionally, a water purifier is known in which tap water once stored in a container is filtered by a filter and the obtained purified water is stored. In FIG. 24, the water purifier proposed by patent document 1 is shown. The water purifier 101 includes a funnel (hereinafter referred to as “raw water container”) 112 that stores tap water that is raw water before purification, a cartridge (hereinafter referred to as “filter cartridge”) 102 that stores filter media, and raw water. A water purification container 111 that stores the purified water that is the filtered tap water while containing the container 112 and the filter cartridge 102 is included. The filter cartridge 102 has an upper portion (hereinafter referred to as “cartridge upper portion”) 102t and a lower portion (hereinafter referred to as “cartridge lower portion”) 102b of the filter cartridge 102 inside and outside of the raw water vessel 112, respectively, at the substantially central portion of the bottom portion of the raw water container 112. It is detachably mounted so as to be located in the position.

  The water purification container 111 is configured integrally with a raw water storage part 111t that stores the raw water container 112 and the cartridge upper part 102t, and a purified water storage part 111b that stores the cartridge lower part 102b and stores purified water. The tap water poured into the raw water container 112 is stored in the raw water container 112, and at the same time passes through the cartridge upper part 102t and the cartridge lower part 102b, and is filtered by the filter cartridge 102 and stored in the purified water storage part 111b. Finally, approximately the same amount of purified water poured into the raw water container 112 is stored in the purified water storage portion 111b.

  In the water purifier 101, the storage volume of the raw water container 112 and the storage volume of the water purification container 111 are preferably configured to be substantially the same in a state where the filter cartridge 102 is attached. That is, the poured tap water is stored in the raw water container 112 and simultaneously filtered by the filter cartridge 102. Therefore, when the raw water container 112 is filled up, the amount of the storage volume of the raw water container 112 is the amount that falls into the water purification container 111. Is set smaller. Thereby, if tap water is poured into the raw water container 112 to the storage volume, after that, tap water is repeated (added), the frequency | count of water injection is few, and the purified water accommodating part 111b can be filled with purified water.

  In FIG. 25, the water purifier proposed by patent document 2 is shown. The water purifier 201 includes a raw water container 212, a filter cartridge 202, and a water purification container 211 that stores the raw water container 212 and the filter cartridge 202 and stores purified water that is filtered tap water. The raw water container 212 includes a raw water storage tank 212b whose side walls are bellows and expands and contracts, and a raw water container 212c provided with an opening substantially at the center of the bottom. The lower end of the side wall of the raw water storage tank 212b is liquid-tightly joined to the periphery of the bottom of the raw water container 212c. The filter cartridge 202 is detachably mounted at a substantially central portion of the bottom of the raw water container 212c (raw water container 212) so that the cartridge upper part 202t and the cartridge lower part 202b are located inside and outside the raw water container 212, respectively. .

  The purified water container 211 is configured integrally with a raw water container 211t that houses the raw water container 212 and the cartridge upper part 202t, and a purified water container 211b that houses the cartridge lower part 202b and stores purified water. The bellows-like side wall of the raw water storage tank 212b is normally folded, and the raw water storage tank 212b is housed inside the raw water container 212c. And when filtering, a bellows-like side wall is extended. Thereby, the storage volume of the raw | natural water storage tank 212b approaches the storage volume of the purified water accommodating part 211b. That is, the volume (volume) of the raw water storage part 211t is smaller than the volume (volume) of the raw water storage part 111t (Patent Document 1).

  Therefore, if tap water is poured into the raw water storage tank 212b in a state where the bellows-shaped side wall is extended, the purified water storage portion 211b is filled with the purified water with a small number of additional water injections thereafter. it can. And after filtration completion, the volume of the water purifier 201 can be made small compared with the time of filtration by folding a bellows side wall and accommodating the raw | natural water storage tank 212b in the raw | natural water container 212c. That is, in the water purifier 201, the volume (volume) of the raw water storage tank 212b required for water purification is increased / decreased before and after filtration, thereby newly requiring a storage location for the raw water container 211t or the raw water container 212. Instead, it achieves improved storage efficiency in the refrigerator, which is required for storage of clean water.

JP 2010-162513 A JP 2010-234286 A

  In Patent Document 1, the storage volume required for the filtration and storage of raw water (the sum of the storage volume of the raw water container 112 and the storage volume of the water purification container 111 in a state where the filter cartridge 102 is attached) (half of the water purification container 111b). However, it can only be used to store purified water. From the viewpoint of downsizing the water purifier, the raw water storage portion 111t is unnecessary after the raw water is filtered, and can be said to be a useless long product. In particular, when storing the purified water for each water purifier in the refrigerator, members unnecessary for storing the purified water, such as the raw water container 112 and the filter cartridge 102, waste the storage space in the refrigerator.

  In order to improve the storage efficiency in the refrigerator, the raw water storage portion 111t and the raw water container 112 are configured to be detachable from the purified water storage portion 111b and are attached to the water purifier 101 (purified water storage portion 111b) only when the tap water is filtered. It is possible. In this case, although the utilization efficiency of the storage space in the refrigerator is improved, a new storage place for storing the raw water storage portion 111t and the raw water container 112 removed from the water purifier 101 after filtration is required separately from the water purifier 101. Is done.

  Moreover, in the same water purifier 201 of patent document 2, the bellows-like side wall of the raw water storage tank 212b is deteriorated and damaged due to repeated expansion and contraction, and a problem occurs when raw water is filtered. For example, the stretched bellows-shaped side wall is shrunk or cut off by its own weight, and tap water overflows or leaks from the raw water container 212 (raw water reservoir 212b or raw water container 212c). In either case, it interferes with the filtration of the raw water, and the raw water is mixed into the purified water after filtration or flows out of the water purifier 201 and wets the surroundings. In addition, the stretchable bellows-like side wall is difficult to clean.

  An object of this invention is to provide the water purifier which can reduce a volume from the time of filtration in the state which accommodated the raw | natural water container in view of the above problems.

In order to solve the above problems, the present invention is a water purifier for producing purified water by filtering raw water with a filter,
