  The pot type water purifier 1 mainly includes a main body container 2, an inner container 3, a stopper 4, an inner lid 10, and a cartridge 5.

  The main body container 2 is a bottomed cylindrical container having an open top, and a clean water spout 7 is formed in a part of the opening. An inner container receiving portion 9 is provided on the inner surface of the main body container 2, and engages with a convex portion of the inner container 3 to fix the inner container 3. As the inner container fixing method, a bayonet method, a fitting method, a screw method, or the like can be used. As shown in FIG. 1, there is a space between the inner surface of the main body container and the outer surface of the inner container other than the inner container receiving portion 9 so that the purified water stored in the purified water storage section 6 of the main body container 2 can circulate. It has become. The shape of the main body container 2 is preferably a substantially rectangular parallelepiped for ease of holding and stability when placed horizontally. Of course, besides the rectangular parallelepiped, the horizontal cross-sectional shape may be a circle, an ellipse, a gourd shape, or the like.

  The inner container 3 is cylindrical and has openings at the top and bottom. The opening at the bottom forms a cartridge connecting portion, and the cartridge 5 is inserted and mounted.

  The plug 4 has a plate-shaped portion, a cylindrical plug male screw 14 formed below the periphery thereof, and a handle 8 (handle) formed on the upper surface of the plate-shaped portion. A seal 12 which is a main body container seal member mounted on a packing groove provided on the plug male screw 14 is rotated and screwed into a main container female screw 13 formed on the upper inner surface of the main container 2. The main body container 2 is sealed with the stopper 3 by pressing against the sealing surface provided on the main body container female screw 13 and compressing in the vertical direction. On the contrary, a structure in which a female screw is formed on the stopper 4 and a screw is formed on the main body container 2 to be screw-coupled is also possible. The position where the packing 12 is provided may be under the plug male screw 14. The male screw, the female screw, and the main body container sealing member constitute main body container sealing means.

  The main body container sealing means is not limited to this embodiment. For example, the main body container sealing means is mechanically sealed with a member having a claw used for a lunch box lid, or the stopper 4 and the main body container 2 are mutually connected. A structure in which concave and convex portions to be engaged are formed and fitted, a structure in which sealing is performed using elasticity of the material of the stopper outer surface itself, and the like may be used. Moreover, the mechanism sealed by the combination of a patchon tablet and a sealing member may be sufficient. Furthermore, sealing may be performed by compressing the packing which is a main body container sealing member not in the vertical direction but in the radial direction (horizontal direction).

  The inner lid 10 is substantially plate-shaped, and a large O-ring 15 as a seal member is attached to the outer surface of the inner lid 10, and the large O-ring 15 is interposed to be fitted and fixed to the upper opening of the inner container 3. The upper opening of the container 3 is sealed. The fixing method of the inner lid 10 to the upper opening of the inner container 3 may be another method such as a screw method. In FIG. 1, the inner lid 10 has a thin plate shape, but may have another shape such as a strong curved surface. A thin flat plate is preferable because it is compact and does not create a useless space inside the main body container 2.

  The inner lid 10 is provided with a raw water supply port 11 for supplying raw water to be purified by the cartridge 5. As shown in FIG. 3, a flat portion (inner lid flat portion 17) is formed at the periphery of the raw water inlet 11, and there is an O-ring groove, and a small O-ring 16 (raw water inlet seal member) is attached. Has been. A plate-like portion of the plug 4 is located above the raw water supply port 11, and a flat portion 18 of the plug is located at a position of the plate-like portion of the plug 4 facing the flat portion 17 of the inner lid. Is formed. And when sealing the main body container 2 with the stopper 4, the flat part 18 of a stopper compresses the small O-ring 16, and it is comprised so that the raw | natural water feed port 11 may be sealed. In this embodiment, the small O-ring 16 (raw water supply port sealing member), the O-ring groove of the flat portion 17 of the inner lid, and the flat portion 18 of the stopper form the raw water supply port sealing means. If the plate-like portions of the inner lid 10 and the stopper 4 are flat as a whole, the inner lid flat portion 17 and the stopper flat portion 18 described above need not be further formed as shown in FIG. In addition, when a step is provided in a slightly convex shape from the other flat portions to form the flat portion 17 of the inner lid and the flat portion 18 of the stopper, the tightening force when the main body container 2 and the stopper 4 are sealed is concentrated. Since it works on the part of the raw water supply port sealing means, it can be effectively sealed. Further, when the raw water supply port sealing means is released (when opening), if the small O-ring 16 may stick to the flat surface portion 18 of the plug, for example, the inlet of the O-ring groove is narrower than the bottom of the groove. It is also preferable to make the shape (so-called dovetail groove) to prevent sticking.

  The sealing structure / means of the raw water supply port 11 by the plug 4 (raw water supply port sealing means) is as long as the raw water supply port 11 is sealed by the plug 4 when the main body container 2 is sealed by the plug 4. For example, a cylindrical portion or a column portion protruding from the plate-like portion of the stopper 4 toward the raw water supply port 11 of the inner lid 10 is provided, and O or the like is provided on the outer peripheral surface of the cylindrical portion or the column portion. When the ring (raw water supply port seal member) is attached and the cylindrical portion or the column portion is inserted in the lower direction of the raw water supply port 11, the O-ring is compressed in the radial direction between the inner surface of the raw water supply port 11. Thus, a structure in which the raw water supply port 11 is sealed is possible.

  3 and 4, when the main body container 2 is sealed with the stopper 4, the raw water supply port 11 is sealed with the stopper 4, and when the main container 2 is unsealed with the stopper 4 ( At the same time, the sealing of the raw water supply port 11 by the plug 4 is released at the same time, but the compression allowance of the raw water supply port seal member and the main body container seal member is adjusted, or the length of the cylindrical part or column part or the raw water supply Even when the thickness of the mouth 11 (the thickness of the inner lid 10) is adjusted and the sealing of the main body container 2 by the stopper 4 starts to be released, the sealing of the raw water supply opening 11 by the stopper 4 is not immediately released. It may be configured as follows.

  The position where the raw water supply port 11 is arranged on the inner lid 10 may be anywhere from the viewpoint of supply of the raw water and sealing of the raw water supply port 11, but as will be described later, when the purified water is poured, the raw water in the inner container is the raw water. From the viewpoint of preventing leakage from the water supply port 11, a deflected position in a direction away from the spout 7 of the main body container 2 in the horizontal direction of the inner lid 10 is desirable as shown in FIG. 4. That is, in this embodiment, the raw water supply port 11 is provided at a position deflected to the right side (the direction away from the spout 7 of the main body container 2) from the center of the circular inner lid 10 as shown in FIG. The deflected position in the direction away from the spout of the main body container in the horizontal direction of the inner lid is not limited to the embodiment of FIG. 4 and is in the direction away from the spout of the main body container in the horizontal direction as shown in FIG. It means the position in the half area of the inner lid (raw water inlet arrangement area 19 shown by diagonal lines). Similarly, when the inner lid is not circular, it means the position in a half region in the horizontal direction away from the spout of the main body container in the area of the inner lid.

  In addition, the size of the opening of the raw water supply port 11 is preferably less than half of the area of the inner lid 10 from the same viewpoint. However, if the opening of the raw water supply port 11 is too small, it becomes difficult to supply water when supplying the raw water supplied from the water tap, so the opening of the raw water supply port 11 is equal to or larger than the diameter of the tap, for example, the diameter It is convenient at the time of raw water supply that it is 20-30 mm or more. Further, the shape of the raw water supply port 11 is usually preferably circular in terms of formation or design, but may be other shapes such as a polygon or a crescent.

  Each of the main body container 2 and the inner container 3 and the inner container 3 and the inner lid 10 is arranged so that the raw water supply port 11 is disposed at a position deflected in the direction away from the spout 7 in the horizontal direction of the inner lid 10. When the fixing method is the vertical fitting method, a positioning engaging part with the circumferential position of the fitting as the required position is provided on both fitting members, and in the case of the screw method or bayonet method, it is tightened and fixed. It is necessary to design the positions of the screws and bayonet so that the completed circumferential position becomes the required position.

  The cartridge 5 includes 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.

  The main container 2, the inner container 3, the stopper 4, and the inner lid 10, which are the main components of the pot-type water purifier 1, are easy to manufacture and inexpensive if they are resin molded products. 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 high impact polystyrene, and the like can be used. The pot-type water purifier 1 is conveniently a transparent container that allows easy confirmation of the filtration state and the amount of purified water. In particular, the main body container 2 and the inner container 3 are highly transparent polystyrene (including high-impact polystyrene) or AS resin (acrylonitrile styrene resin). ) Is preferred.

  Silicone rubber was used for the sealing members such as the packing 12, the large O-ring 15, and the small O-ring 16 as an elastic body having a high sealing performance. Other EPDM rubbers can also be used.

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

  FIG. 4 is an enlarged cross-sectional view of the upper part of the pot-type water purifier 1 in a state in which the handle 4 is held in the fully closed sealed state of FIG. However, the plug is further opened from the state, and the plug 4 is removed from the main body container 2. Then, when raw water is supplied to the inner container 3 from the raw water supply port 11 of the inner lid 10, the raw water passes through the upper opening mesh member from the upper opening portion of the cap of the cartridge 5 at the same time, and at the same time is the raw water collecting portion. It is guided to the filter material filling part through the inner mesh member. Thereafter, the cartridge is purified by the filter medium in the filter medium filling portion, and passes through the cartridge 5 through the outer mesh member and six slits 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 collected as purified water in the purified water reservoir 6 below the main body container 2.

  Here, holding the handle 8, the stopper 4 is attached to the main body container 2, is rotated in the sealing direction, and is again opened 90 ° as shown in FIG. 4. In this state, the sealed state between the stopper 4 and the main body container 2 is released, and the sealing of the raw water inlet 11 of the inner lid 10 by the stopper 4 is also released, so as shown by the arrow in FIG. External air passes through the gap between the female screw 13 and the male screw 14 of the main body container, passes through the gap between the outer surface of the stopper 4 and the inner container 3 and the raw water supply port 11 in this order, and enters the inside of the inner container 3. Inflow is possible. Therefore, even in this state, the raw water remaining in the inner container 3 is continuously purified through the cartridge 5, and the purified water continues to accumulate in the purified water storage section 6.

  The purified water may be taken out from the spout 7 after all of the raw water has been purified, but in the pot-type water purifier 1 of the present embodiment, the raw water still remains in the inner container 3 in the state of FIG. Even in the middle of purification, the pot-type water purifier 1 can be tilted as shown in FIG. That is, even if the pot-type water purifier 1 is tilted with the raw water still remaining in the inner container 3 as shown in FIG. 5, the inner lid 10 seals the upper opening of the inner container 3. The raw water in the inner container 3 leaks out and does not flow into the purified water to be taken out. In particular, as shown in FIG. 4, when the raw water supply port 11 is arranged at a deflected position away from the spout 7 in the horizontal direction of the inner lid 10, even if the pot-type water purifier 1 is inclined, Since the raw water does not leak from the raw water supply port 11, only purified water can be taken out from the spout 7 more completely.

  If the purified water is not taken out immediately after the purification of the raw water or after the purification is completed, the stopper 4 is rotated to the state shown in FIG. As described above, in the present embodiment, at this time, the raw water supply port 11 of the inner lid 10 is also sealed with the stopper 4 at the same time. Therefore, in this sealed state, even if the pot type water purifier 1 is placed not only vertically but also horizontally, the purified water and raw water do not leak to the outside, and the raw water does not leak into the purified water. Therefore, even when there is no place in the door pocket of the refrigerator, it is possible to obtain a great effect that the pot-type water purifier 1 can be refrigerated and stored horizontally on an empty refrigerator storage shelf.

  It is convenient because the pot-type water purifier 1 can be moved by holding the handle 8 provided in the stopper 10 when the pot-type water purifier 1 is moved or when it is horizontally placed in and out of the refrigerator. Furthermore, even when the pot-type water purifier 1 is stood and stored in a drawer at a low position in the refrigerator such as a vegetable room, the pot-type water purifier 1 can be pulled up easily by grasping the handle 8. Can do.

  The cartridge 5 is attached to the cartridge connecting portion at the opening at the bottom of the inner container 3, but three cartridge fixing protrusions are arranged at equal intervals (not shown) on the inner wall of the cartridge connecting portion. When repeatedly performing the operation of placing the pot type water purifier 1 upright or tilting it sideways, the force of the moment may be applied to the cartridge connection part due to the weight of the cartridge 5, and the cartridge connection part may come loose. However, when the fitting with the cartridge 5 is strengthened by the fixing protrusion, there is no room for the cartridge 5 to be inclined, and it is possible to prevent the cartridge 5 from being loosened.

  In addition, the embodiment of the present invention can be modified as follows.

  The sealing member of the pot-type water purifier of the present invention may be a flat packing, an O-ring, or a member, as long as the pot-type water purifier exhibits a sealing effect so that each of the raw water and the purified water does not leak when placed sideways. It may be an elastic body such as a silicone member that is specially molded so as to be fitted to.

  The seal member may be attached to any one of the two members that form a seal. In the above embodiment, the packing 12 which is a seal member of the main body container sealing means is attached to the stopper 4, but the packing 12 may be attached to the main body container 2. Similarly, the sealing member of the raw water supply port 11 of the inner lid 10 may be attached to the stopper 4.

  The main body container internal thread 13 and the plug male thread 14 may be provided on the entire upper inner surface of the main body container and the entire lower outer surface of the plug, respectively, or may have a partially deleted shape.

  In the above-described embodiment, the raw water supply port is provided in the inner lid. However, the inner lid may be a simple plate having no openings or holes including the raw water supply port. For example, only a small hole with an air vent of about 1 mm in diameter may be provided in the inner lid, but since the raw water leaks out when the pot type water purifier is placed horizontally, it is not preferable as a horizontally placeable type.

  If there is no opening or hole in the inner lid, a sealing member for sealing the inner container is attached to the inner lid, and when the inner container is attached and fixed by the fitting method or screw method, the raw water in the inner container is completely sealed The raw water does not leak out to the outside or to the purified water storage section when pouring clean water or when placing the pot type water purifier horizontally. In this case, the raw water is supplied after removing the stopper from the main body container, then removing the inner lid from the inner container and opening the upper part of the inner container. Then, after the purification of raw water is completed, the usage procedure is to attach the inner lid to the inner container again.

  The above embodiment in which the inner lid has no openings or holes can be further modified. That is, when the stopper is attached to the main body container, the inner lid and the stopper are engaged. And the engagement strength is made larger than the attachment (engagement) strength of the inner lid to the inner container. This makes it possible to remove the inner lid from the inner container at the same time that the stopper is removed from the main body container. When supplying raw water, there is no need to perform a double operation of removing the stopper and the inner lid. It becomes. As a specific structure, for example, a concave portion (or convex portion) is provided in the center of the upper surface of the inner lid, and a convex portion (or concave portion) is provided in the center of the bottom surface of the stopper plate-like portion. In this structure, the inner lid and the plug are unevenly fitted. Even if the unevenness is fitted, it is even better if it can be rotated around the vertical axis because it can be attached and detached without any problem even if the stopper and the main body container are attached by a screw method. At this time, the attachment method of the inner lid and the inner container is also made by vertical fitting.

  The present invention can be applied not only to pot-type water purifiers but also to liquid containers for storing tea leaves or coffee powder and storing tea or coffee inside, but the application range is limited to these. It is not a thing.
