Description

  The present invention relates to a domestic water purifier that is mainly used at home and filters tap water. It especially relates to pot-type water purifiers.

  The conventional pot type water purifier is composed of a lid with a spout, a raw water container, and a main body container for storing purified water, and is used with a cartridge attached to the raw water container. Each member is fixed by fitting, and the tap water put in the raw water container passes through the cartridge by its own weight and becomes purified water (Patent Document 1). Pot-type water purifiers are often used for drinks, and users usually store them in a refrigerator.

  However, the storage location of the refrigerator, particularly the door pocket, is limited in the location where the pot-type water purifier can be stored, and there are many users who are in trouble with the storage location. Nevertheless, when the filtration is completed, a pot-type water purifier having a large volume main body container including a raw water container that becomes a useless space has to be stored. This is also a problem that because of the space of the raw water container, a large amount of purified water cannot be stored and stored for the volume of the main body container.

  The structure of the pot type water purifier 1 is demonstrated using FIG. 7 and FIG.

  The pot type water purifier 1 mainly includes a main body container 2, a raw water container 3, a lid 4, a holding member 10, and a cartridge 5.

  The main body container 2 is a bottomed cylindrical container having an upper opening having a spout 7. A holding member receiving screw 9 is provided on the inner side surface of the main body container 2 and engages with a holding member male screw 11 formed on the outer side surface of the holding member 10, and the holding member 10 is attached and fixed to the opening of the main body container 2. Has been. As the holding member fixing method, other bayonet methods, fitting methods, and the like can be used. There is a space between the inner surface of the main body container other than the holding member receiving screw 9 and the outer surface of the holding member, and the purified water stored in the purified water storage section 6 of the main body container 2 can be distributed. The shape of the main body container 2 is preferably a substantially rectangular parallelepiped for ease of holding, stability when placed horizontally, and space saving during storage. Of course, in addition to a rectangular parallelepiped, the horizontal cross-sectional shape may be a circle, an ellipse, a gourd shape, or the like, and may have a handle. The spout 7 may not be provided in the upper opening portion of the main body container 2 but may be provided on the upper side surface of the main body container 2 with a small lid that can be opened and closed in a watertight manner.

  The lid 4 has a plate-like portion, a cylindrical lid male screw 14 formed below the periphery of the plate-like portion, and a handle 8 (handle) formed on the upper surface of the plate-like portion. The lid male screw 14 is rotated and screwed into a lid receiving screw 13 formed on the upper inner surface of the holding member 10, and the raw water packing 12 is a holding member sealing member mounted in a packing groove provided on the lid male screw 14. Is brought into contact with a sealing surface provided on the lid receiving screw 13 to seal the space between the holding member 10 and the lid 4 in a watertight manner. The method of contacting the raw water packing 12 includes a method of compressing the raw water packing 12 in the vertical direction, a method of circumferentially contacting the side surface of the raw water packing 12 with the inner surface of the holding member 10 and compressing the raw water packing 12 in the radial direction (horizontal direction), and the like. Any method can be used as long as it can maintain the watertight seal performance. Further, the position where the raw water packing 12 is provided may be under the lid male screw 14. As a method for attaching the lid, other bayonet methods, fitting methods, and the like can be used.

  The holding member 10 has openings at the top and bottom. The lower opening forms a cartridge mounting portion, and the cartridge 5 is detachably inserted and mounted. A cover receiving screw 13 is provided inside the upper portion of the holding member 10, and a holding member male screw 11 is provided outside.

  The holding member 10 is used by being attached to the upper opening of the main body container 2. The holding member male screw 11 is rotated and screwed into a holding member receiving screw 9 formed on the upper inner surface of the main body container 2, and is a main body container sealing member mounted in a packing groove provided on the holding member male screw 11. The clean water packing 22 is brought into contact with a sealing surface provided on the holding member receiving screw 9 to seal the space between the main body container 2 and the holding member 10 in a watertight manner. The main body container 2 is sealed together with the watertight seal between the holding member 10 and the lid 4 described above. The contact method of the purified water packing 22 is a method of compressing the purified water packing 22 in the vertical direction, a method of circumferentially contacting the side surface of the purified water packing 22 with the inner surface of the main body container 2, and compressing the purified water packing 22 in the radial direction (horizontal direction). Any method can be used as long as it can maintain the watertight seal performance. On the contrary, a structure in which a female screw is formed on the holding member 10 and a screw is formed on the main body container 2 to be screw-coupled is also possible. Moreover, the position where the water purification packing 22 is provided can be under the male screw 11 of the holding member.

  As shown in FIG. 7, with the lid 4 mounted, the upper end of the cartridge 5 is as close as possible to the position of the lower surface of the lid 4 (for example, the gap between the upper end of the cartridge 5 and the lower surface of the lid 4 is 5 mm or less). ), The cartridge 5 is preferably attached to the holding member 10. By doing so, the space related to mounting of the cartridge 5 in the volume in the main body container 2 can be reduced, and more purified water can be stored in the main body container 2. The preferred mounting position of the cartridge 5 is equally desirable in other embodiments described later. Of course, a more compact cartridge in the same sense is also preferred.

  The raw water container 3 has a raw water supply port 15, a raw water storage part 16 that stores the supplied raw water, and a raw water outflow part 18 that has a raw water outlet 17 and flows the stored raw water into the cartridge 5. It has. The outer surface of the raw water outflow portion forms a mounting portion 19 for mounting the raw water container 3 to another member (the holding member 10 in the embodiment of FIG. 8). The raw water storage part 16 is located vertically above the raw water outflow part 18 (and the mounting part 19). The attachment part 19 of the raw water container 3 has the same structure as the attachment means (lid male screw 14) of the lid 4 so that the raw water container 3 can be attached to the place where the lid 4 was removed and the lid 4 was attached. ing. That is, the raw water container 3 and the lid 4 can be detached from each other and attached instead of one.

  The raw water container 3 is mounted such that the raw water storage section 16 is positioned vertically above the opening surface 21 of the main body container. The raw water storage section 16 has a large volume of the raw water container 3 so as to reduce the space that is compact and useless for storing the purified water in the storage state shown in FIG. 7 with the raw water container 3 removed and the lid 4 attached. It is preferable that the size occupies a portion (for example, 70% or more), and the raw water outflow portion 18 and the mounting portion 19 which are other portions of the raw water container 3 are preferably as small as possible.

  For this reason, as shown in FIG. 8, it is a preferable aspect to make the outer diameter of the raw water reservoir 16 larger than the outer diameter of the main body container 2.

  The mounting means and the sealing member for the lid 4 (and the raw water container 3) to the holding member 10 and the mounting means and the sealing member for the holding member 10 to the main body container 2 are not limited to this embodiment. , For example, a structure that is mechanically sealed with a member having a claw used for a lid of a lunch box, a structure in which concave and convex parts that engage each other are formed and fitted, and the material itself A structure that seals using elasticity may be used. Moreover, the mechanism sealed by the combination of a patchon lock | rock and the member for sealing may be sufficient. Furthermore, if the dimensional accuracy of engagement and fitting between members is strict, watertight sealing and sealing can be performed without a sealing member.

  The cartridge 5 is composed of, for example, a cap, a filtration filter, and an outer case. The filtration filter is connected to the lower center position of the cap, and the outer case is connected to the lower part of the cap so as to cover the filtration filter. The filtration filter has a cylindrical outer mesh member and an inner mesh member, the internal space of the inner mesh member is a raw water collecting portion, and the space between the outer mesh member and the inner mesh member is a filter material filling portion. The filter medium filling part is filled with activated carbon, ion exchange resin or the like.

  If the main body container 2, the raw water container 3, the lid 4 and the holding member 10, which are the main components of the pot-type water purifier 1, are resin molded products, they are easy to manufacture and inexpensive. As the resin material, polystyrene (including high impact polystyrene), AS resin (acrylonitrile styrene resin), polycarbonate, acrylic resin, polyethylene, ABS resin (acrylonitrile butadiene styrene resin), polypropylene, and the like can be used. The pot-type water purifier 1 is conveniently a transparent container in which the filtration state and the amount of purified water can be easily confirmed. In particular, the main body container 2 and the raw water container 3 are preferably highly transparent polystyrene or AS resin (acrylonitrile styrene resin).

  Silicone rubber was used as an elastic body having a high sealing property for sealing members such as the raw water packing 12 and the purified water packing 22. Other EPDM rubbers can also be used.

  Next, the usage method and function of the pot type water purifier 1 which is embodiment of this invention are demonstrated.

  In FIG. 7, the screw fixing of the holding member 10 is loosened, and the lid 4 is removed with a gap between the inner surface of the main body container 2 and the holding member 10, and the raw water container is used instead of the lid 4 as shown in FIG. 3 is attached to the holding member 10. When the raw water is poured from the raw water supply port 15 above the raw water container 3, the raw water is stored in the raw water storage unit 16, flows down by its own weight, flows out from the raw water outlet 17, and the upper part of the cap of the cartridge 5. It passes through the upper opening part mesh member from the opening part, and is simultaneously guided to the filter medium filling part through the inner mesh member which is the raw water collecting part. Thereafter, the cartridge 5 is purified by the filter medium in the filter medium filling portion, and passes through the cartridge 5 through the outer mesh member and a slit provided in the length direction extending to the lower end of the outer case. While passing through the cartridge 5, free residual chlorine and the like in the raw water are removed and accumulated as purified water in the purified water storage section 6 below the main body container 2. After completion of the filtration, the raw water container 3 is removed, the lid 4 is attached to the attachment portion of the raw water container 3, and the state is returned to the state shown in FIG. Thereby, a large amount of purified water can be made and stored in the main body container 2 by a single filtration, and space-saving storage without wasted space can be realized. Since the main body container 2 is hermetically sealed, clean water does not spill even when stored in a horizontal position, and can be stored in any direction or place. Further, since the cartridge 5 can be stored while being left in the main body container 2, the storage method is not troublesome and is hygienic.

  In the case of using purified water, in FIG. 7, the screw fixing of the holding member 10 is loosened, and the purified water is poured out from the spout 7 with a gap between the inner surface of the main body container 2 and the holding member 10.

  Although not shown in FIG. 7, for example, a plurality of protrusions are provided on the outer peripheral surface of the upper end of the holding member 10 so that the screw fixing of the holding member 10 can be easily loosened or tightened, and the holding member is hung with a finger. It is a preferable aspect that the 10 can be rotated. Further, the screw fixing of the holding member 10 is loosened, and the holding member male screw 11 and the holding member are immediately formed so that a sufficient gap is formed between the inner surface of the main body container 2 and the holding member 10 for pouring clean water. It is preferable that the receiving screw 9 is not an all-around screw but has a screw-free portion that can become a gap. Furthermore, the upper and lower portions of the screw engagement between the inner surface of the main body container 2 and the holding member 10 have a stepped or tapered shape, and when the screw fixing of the holding member 10 is loosened, the inner surface of the main body container 2 and the holding member 10 It is also preferable to create a gap between them.

  In the above description, the main body container 2 and the holding member 10 and the holding member 10 and the lid 4 are sealed in a watertight manner so that the main body container 2 can be sealed. Watertight sealing and sealing are not always essential. It is only necessary to determine the positions of the members to be attached to each other in a vertically placed state that can be filtered by a mounting method such as simple screw connection or fitting without a sealing member interposed therebetween. In this case, the configuration is simple, the assembly and handling are facilitated, and it can be manufactured at low cost. Since the opening of the main body container 2 is covered by the lid 4 (and the holding member 10), as in the case of FIG. The water purifier can be stored.

The raw water container 3 to which the cartridge 5 is attached is attached to the opening of the main body container 2. When raw water is poured from the raw water supply port 15 above the raw water container 3, the raw water passes through the cartridge 5 by its own weight as in FIG. 8 and accumulates in the purified water storage section 6 below the main body container 2 as purified water. After the filtration, the cartridge 5 and the raw water container 3 are removed, the lid 4 is attached to the attachment part of the raw water container 3, and the main body container is stored in the sealed state shown in FIG.

  Thereby, in this embodiment, it becomes a simple structure without a holding member, and a large amount of purified water can be created and stored in the main body container 2 by a single filtration, and there is also no space-saving space. Storage can be further realized.

  Since the main body container 2 is hermetically sealed, clean water does not spill even when stored in a horizontal position, and can be stored in any direction or place. Further, since the cartridge 5 is attached to the raw water container 3, it is easy to attach and detach the raw water container and the cartridge.

  In the case of this embodiment, the shape of the raw water outflow portion 18 is changed to the extent that the cartridge 5 is moved upward, for example, the upper end of the cartridge 5 partially enters the raw water storage portion 16 as shown in FIG. It is a preferable aspect for the purpose of securing the clean water storage space in the above-mentioned main body container 2 and the space-saving storage without useless space. This aspect can also be applied to the embodiment of FIG. 2 below.
