Description

  The present invention relates to a domestic water purifier that is mainly used at home and filters tap water.

  Currently, a pot-type water purifier that is widely used is equipped with a filtration cartridge filled with a filter medium such as activated carbon or a hollow fiber membrane.

  However, the cartridge has a lifetime, and when the filtration capacity decreases, the user replaces it with a new cartridge.

  2. Description of the Related Art Conventionally, a water purifier having a function of displaying a cartridge filtration capacity decline time on a water purifier in advance with a date and allowing a user to change the cartridge without forgetting is known.

  In patent document 1, the replacement time display member is provided in the handle. The replacement time display member is fitted into a notch frame provided on the handle and is movable in the longitudinal direction of the handle. The protrusion provided on the replacement time display member and the plurality of recesses carved in the handle are locked to each other, and the replacement time display member stops at each recess. A cover constituting the back surface of the gripping portion is connected to the handle, and a number indicating a cartridge replacement guide time is engraved on the cover. The user can visually check the replacement time display member from the back of the handle cover, and can read the replacement time of the cartridge from the stop position of the replacement time display member and the date of the cover.

  However, when the conventional cartridge replacement time display member moves along the longitudinal direction of the handle, it is moved while gripping the back surface of the surface provided with the projection.

  Originally, when the convex moves from concave to concave, it is necessary to bend the surface provided with the convex, but with conventional cartridge replacement time display members, the portion to be bent is pressed with a finger, and the convex wear is large. There was a case.

  In such a case, the use of the cartridge replacement time display member and the handle becomes weaker as it is used, causing a problem that the position of the cartridge replacement time display member changes without permission.

  A water purifier according to an embodiment of the present invention will be described with reference to the drawings. In addition, this invention is not limited to embodiment shown below, What is necessary is just to be able to achieve the said objective of this invention.

  FIG. 1 and FIG. 2 show an outline of a water purifier that is one embodiment of the present invention. The water purifier 4 according to the present embodiment includes a main body 1 and a cartridge 2 for purifying raw water. The main body 1 includes a main body container 11, a raw water container 51, a lid 71, a spout cover 91, and a cartridge 2. The replacement time display member (cartridge replacement time display member 111) and the handle cover 31 are configured.

  A raw water container 51 is accommodated and attached above the main body container 11, and a lower part is a purified water storage part. The main body container 11 includes a main body container handle 12. The lid 71 is attached above the raw water container 51. The spout cover 91 is connected to the spout cover connection part 72 of the lid 71. The cartridge replacement time display member 111 is connected to the main body container handle 12 provided in the main body container 11, and the handle cover 31 covers the cartridge replacement time display member 111 and covers the back surface of the main body container handle 12. Is connected to the main body container handle 12 so as to form the handle 3 as follows. The cartridge 2 is mounted in a hole 52 opened at the bottom of the raw water container 51.

  In the state of FIG. 1, when the lid 71 is removed and tap water is put into the raw water container 51, the tap water passes through the cartridge 2 by its own weight, and water is collected in the main body container 11 as purified water. In order to filter all the raw water poured into the raw water container 51, the water level of the purified water needs to be located below the bottom surface of the raw water container. The clean water full state is a state where the water level of the purified water is at the bottom of the raw water container.

  Moreover, when pouring purified water, if the cover 71 is attached and the main-body part 1 is inclined, purified water can be poured from the spout 13 provided in the upper edge part of the main body container 11. FIG.

  The main body container 11 will be described with reference to FIGS. 1 and 3.

  The main body container 11 is provided with a spout 13 for pouring purified water at the top, and a main body container handle 12 is provided on the opposite side. The shape of the portion of the main body container 11 excluding the main body container handle 12 has a gourd shape having a constriction near the center in a side view. On the other hand, the outline of the main body container 11 including the main body container handle 12 (and the main body 1 and the entire water purifier 4) is substantially rectangular.

  The space for storing the purified water in the main body container 11 is composed of a first space 30 located below the raw water container 51 and a convex second space 29 located on the side of the first space 30. ing. One end of the main body container handle 12 is connected above the second space 29 that stores the purified water, and the second space 29 is located below the main body container handle 12. For this reason, the space under the handle (the main body container handle 12 and the handle 3) is replaced with a purified water storage space, and even if the purified water capacity that can be stored is the same as that of the conventional case, the space can be made compact and easy to store. In this embodiment, the purified water storage capacity of the second space 29 is about 0.2 times the purified water storage capacity of the space for storing purified water. In order to effectively utilize the space below the handle as the purified water storage space and keep the shape of the main body container easy to accommodate, the purified water storage capacity of the second space is the purified water storage capacity of the space for storing the purified water. Is preferably 0.1 to 0.3 times.

  The main body container 11 has a bottom surface 14 and a side surface 15 made of different members, and they are connected in a liquid-tight manner by ultrasonic welding. It may be fixed with an adhesive in addition to ultrasonic welding, and is not limited to ultrasonic welding as long as it can be liquid-tightly fixed.

  The bottom surface 14 and the side surface 15 can be integrally formed by blow molding without using separate members. However, the main body container handle 12 becomes hollow, making it difficult to clean the inside of the main body container handle 12. Therefore, as in the present embodiment, the bottom surface 14 and the side surface 15 are preferably manufactured as separate members. It is sufficient that two or more members are connected in a liquid-tight manner, and the bottom surface 14 and the side surface 15 are not necessarily separate members. For example, in FIG. 3, the upper and lower two members may be connected in a liquid-tight manner at the gourd-shaped constricted portion of the main body container.

  The main body container 11 is conveniently a transparent container that allows easy confirmation of the filtration state and the purified water storage capacity, and is preferably an AS resin (acrylonitrile styrene resin) or polystyrene having high transparency. In addition, resin molded products such as polypropylene, polycarbonate, acrylic resin, polyethylene, and ABS resin (acrylonitrile butadiene styrene resin) may be used.

  Next, the main body container handle 12 and the handle 3 will be described with reference to FIGS. 3, 4, 5, and 6.

  In the description of the present invention, for convenience of description of the structure, the two terms of “main body container handle” and “handle” are used separately, both of which function to hold the water purifier. And can be interpreted in the meaning of “handle” as a general term.

The handle cover 31 (and the cartridge replacement time display member 111) is connected to the main body container handle 12 of the main body container 11, and the handle 3 having the entire handle function in the present invention is formed. The handle 3 is divided into a grip 18, an upper end connection portion 16, and a lower end connection portion 17, and the lower end connection portion 17 is connected above the second space 29 that stores purified water. (The upper end connection portion 16 and the lower end connection portion 17 are also portions constituting the main body container handle 12.)
The space for inserting the finger of the main body container handle 12 (and the handle 3) is located on the inner upper side from the edge 28 on the bottom surface of the main body container. In the pot type water purifier provided with the conventional handle, the handle protrudes from the main body container, and the handle becomes an obstacle when stored in the refrigerator (Patent Documents 2 and 3). In the main body container handle 12 (and the handle 3) of this embodiment, a space for inserting a finger is accommodated inside the edge 28 on the bottom surface of the main body container. As a result, the water purifier can be made more compact, and the space for inserting the handle fingers is closer to the center of gravity of the water purifier than before, so the water purifier that stores the purified water can be used with the bottom surface of the main body container as a table or storage location. It is easy to lift from a state where it is placed on the horizontal plane.

  And as the whole main body container 11 (and main-body part 1 and the water purifier 4), even if it sees from any visual field of not only a side view but a planar view and a front view, the outline is substantially rectangular. Thereby, at the time of storing the water purifier 4 in a refrigerator or the like, the handle can be efficiently stored without being wasted without causing a handle to stick out. Moreover, since the space under the handle that has not been used in the conventional pot-type water purifier with a handle is used as the purified water storage space, the water purifier can be made more compact than before.

  In order to obtain such an effect most, the shape of the handle 3 (and the main body container handle 12) is preferably L-shaped.

  As the shape of the handle 3 (and the main body container handle 12) as viewed from the side of the water purifier, a U-shape can be considered, but the length of the grip portion 18 is relatively larger in the L-shape than in the U-shape. When the length of the handle 3 is L, the length of the U-shaped gripping portion is a, and the length of the L-shaped gripping portion is b, the following expression is obtained.

a / L <b / L
In this embodiment, since the purified water storage space (second space 29) is provided below the handle 3 (and the main body container handle 12), the handle 3 (and the main body container handle 12) should be as short as possible. Therefore, the handle 3 (and the main body container handle 12) can be saved in space by using an L shape with a large ratio of the gripping portion 18, which is a more preferable form.

  Further, the connection surface of the upper end connection portion 16 is substantially vertical, and the connection surface of the lower end connection portion 17 is substantially horizontal and different in direction, and even if it is accidentally dropped, the upper end connection portion 16 and the lower end connection portion 17 are different. Therefore, the main body container handle 12 is less likely to be broken.

  Next, the cross-sectional shape of the main body container handle will be described with reference to FIGS. 14, 20, 21, 22, 23 and 24.

  As for the main body container handle 12, it is desirable that the cross-sectional shape is integrally formed over the whole longitudinal direction. In the conventional water purifier in which the cartridge replacement time display member is connected to the main body container handle, as shown in FIG. 24, the main body container handle 130 is provided with a square cutout frame, and the cartridge replacement time display member 131 is connected to the cut-out time display member 131. It was fitted in a notch frame. However, due to the cutout frame, the cross-sectional shape of the main body container handle 130 is not integrated but is divided, and the strength of the main body container handle 130 is weak and may be broken when dropped. There is.

  Therefore, it is desirable to integrally form the cross-sectional shape of the main body container handle 12 over the entire longitudinal direction without providing a notch frame. In that case, it is preferable that the cross-sectional shape of the holding portion 24 in the main body container handle 12 that fits and holds the cartridge replacement time display member 111 is a character shape having a recess. In particular, as shown in FIGS. 14, 21, 22, and 23, any one of S-shaped, U-shaped, and L-shaped characters having a concave portion 27 can be preferably employed. In the case of these character shapes, the main body container handle 12 (the holding portion 24) is easily manufactured by resin molding. Of course, for example, a substantially C-shaped, a substantially M-shaped, a substantially T-shaped or the like can be used as the character shape. Since such a character shape is a shape having at least a concave portion and a convex portion at the end, the cartridge replacement time display The member 111 can be configured to be fitted and attached to the character-shaped end portion (convex portion) of the cross section of the holding portion 24. Further, as will be described later, the display surface of the cartridge replacement time display member 111 can be provided in the character-shaped recess. Furthermore, it becomes stronger in strength than the conventional product in which the replacement time display member is fitted into the cutout frame as described above. In particular, it is strong against impact and pressing from the convex side which is the opposite surface of the character-shaped concave portion.

  Next, the position of the grip portion 18 of the handle 3 will be described with reference to FIGS. 7, 8, and 9.

  When the main body unit 1 is tilted in a clean water-filled state, purified water begins to be discharged from the spout 13, but a straight line is drawn vertically upward from the center of gravity 19 of the main body unit 1 including the purified water at the tilt angle at which the main water unit 1 starts to discharge. A grip portion 18 of the handle 3 is provided on the straight line.

  When the straight line is gripped and purified water is poured, no rotational moment is generated when water is discharged. Therefore, it does not require a force to counter the rotational moment, so it can be poured stably and easily.

  In a normal cold water cylinder, water can be stored up to the upper end of the container, and therefore the position of the center of gravity is high. In addition, when water is stored up to full water, water is discharged immediately with a slight inclination. In such a cold water cylinder, when it is going to provide a handle on the said conditions, it becomes the shape which the handle protruded upwards and the storing property to a refrigerator is bad. On the other hand, as described above, the pot-type water purifier only collects water up to the bottom surface of the raw water container 51 even when it is full, and the position of the center of gravity 19 is low. Even when the water is full, water is not discharged unless it is tilted to some extent. By further developing the characteristics of such a pot-type water purifier, the water purifier of this embodiment has been devised in which a gripping portion 18 is provided at a position where no rotational moment is generated when water is discharged as described above. . In addition, in the present embodiment, the purified water is also stored below the handle 3, so that the position of the center of gravity 19 is closer to the handle 3 side. Therefore, even if the water level in which the purified water is accumulated is higher than that of the conventional product, the gripping portion 18 can be provided at a location where the rotation moment does not occur without protruding the handle 3 upward.

  Further, it is desirable that the lower end of the grip portion 18 is at a height equivalent to the center of gravity of the main body portion 1.

  That is, when the purified water is emptied, it is necessary to rotate 90 ° from the state where the main body 1 is placed. In that case, in order to be able to grip without generating a rotating moment, the lower end of the grip 18 is It suffices if it is below the center of gravity 19. However, on the other hand, in order to increase the purified water storage capacity, the lower end connection portion 17 of the handle 3 is desired to be provided on the upper side as much as possible. In order to satisfy the above two requirements, it is desirable to provide the lower end connection portion 17 of the handle 3 so that the lower end of the grip portion 18 is at the same height as the center of gravity of the main body portion 1.

  Next, the handle cover 31 will be described with reference to FIGS.

  A handle cover 31 and a cartridge replacement time display member 111 are attached to the main body container handle 12. The handle cover 31 covers the back surface of the main body container handle 12 and forms the back surface side of the gripping portion 18. The handle cover 31 has a substantially semi-cylindrical shape, and the connection side with the main body container handle 12 is hollow. On the other hand, the front side of the main body container handle 12 forms the front side of the grip portion 18. Since the handle cover 31 is mounted, the handle 3 that is easy to hold is formed by the main body container handle 12 and the handle cover 31, and at the same time, the position of the cartridge replacement time display member 111 is accidentally touched by a finger. (That is, erroneous operation) can be prevented.

  A main body container fitting rib 32 arranged in the vertical direction is provided at the lower inner side of the handle cover 31, and is configured to be mounted along the handle cover fitting vertical groove 21 provided at the lower part of the main body container handle 12. . Moreover, the main body container connection convex 33 is provided on the inner upper side of the handle cover so as to face the side surface. A side surface of the upper part of the main body container handle 12 is provided with a handle cover fitting recess 22 for fitting with the protrusion of the handle cover 31.

  The protrusion 33 for connecting the main body container of the handle cover 31 inserts the lower main body container fitting rib 32 into the vertical groove 21 for fitting the handle cover of the main body container handle 12, and then rotates the handle cover 31 with the lower part as a fulcrum. Fit into the cover fitting recess 22. Thereby, the movement in the rotation direction is restricted.

  Further, a locking top plate 34 is provided on the inside upper side of the handle cover 31, and when the handle cover 31 is attached to the main body container handle 12, the handle cover is placed under the top plate 23 provided on the main body container handle 12. The locking top plate 34 is positioned. Thereby, the upward movement of the handle cover 31 is restricted and fixed securely.

  A rib-like finger hooking portion 35 is provided on the upper portion of the handle cover 31. When the handle cover 31 is removed, the finger hooking portion 35 is hooked with a finger, and is removed by rotating the lower portion of the handle cover 31 around a fulcrum.

  Next, the cartridge replacement time display member 111 will be described with reference to FIGS. 12, 13, 14, 15, 16, and 17.

  In FIG. 12, the cartridge replacement time display member 111 has a generally extruded shape of the letter “E”. The cartridge replacement time display member 111 has a handle fitting groove 112, and the handle fitting groove 112 is formed by a fitting groove forming portion 120 that is a part of the cartridge replacement time display member 111 so as to see it from the periphery. ing. The cartridge replacement time display member 111 is inserted between the top plate 23 of the main body container handle 3 and the holding portion 24, and is attached to the holding portion 24 in the main body container handle 12 by the handle fitting groove 112. Therefore, the fitting groove forming portion 120 that forms the handle fitting groove 112 is formed so as to cover at least a part of the main body container handle 12. The cartridge replacement time display member 111 is movable in the longitudinal direction along the holding portion 24 (and the main body container handle 12).

  On the holding part 24 of the main body container handle 12, a plurality of locking recesses 25 having a triangular groove shape in cross section are cut vertically along the longitudinal direction. On the inner surface of the fitting groove forming portion 120 of the cartridge replacement time display member 111 (and on the central beam 113 in the E-shape), a cartridge similar in shape to the locking recess 25 of the handle engraved in the main body container handle 12 A locking projection 114 for the replacement time display member is provided. When the cartridge replacement time display member 111 moves in the vertical direction, the locking concave portion 25 for the handle and the locking convex portion 114 of the cartridge replacement time display member are locked with each other. The cartridge replacement time display member 111 can be fixed and stopped at the position 25.

  In contrast to the present embodiment, the cartridge replacement time display member 111 may have a locking recess and the main body container handle 12 may have a plurality of locking protrusions.

  A part of the fitting groove forming portion 120 (and beam 113) provided with the locking projection 114 of the cartridge replacement time display member is connected to the handle by the locking projection 114 of the cartridge replacement time display member 111. When moving from the locking recess 25 to another locking recess 25, it is necessary to bend. Therefore, the cartridge replacement time display member 111 has the following structure so as not to suppress deflection by gripping the back surface of the locking projection 114 with a finger. That is, the gripping portion 115 and the gripping portion 116 of the cartridge replacement time display member are formed on the outer surface of the fitting groove forming portion 120, and the locking convex portion 114 as viewed from the handle fitting groove 112 of both gripping portions. A slit 119 is provided on a straight line connecting the grip portion 115 and the locking convex portion 114 which is the side on which is formed. Here, since the fitting groove forming portion is defined as a part of the cartridge replacement time display member that is formed so as to look at the handle fitting groove from the periphery, the range of the outer surface thereof is the both ends of the E type in FIG. The outer surface of the side is also included, and the gripping portion 115 and the gripping portion 116 of two cartridge replacement time display members are formed in that portion. Further, the grip portion of the cartridge replacement time display member is a part for moving the cartridge replacement time display member by grasping with both fingers, not the entire outer surface of the fitting groove forming portion. Of course, both the gripping portions of the gripping portion 115 and the gripping portion 116 are a part of the fitting groove forming portion of the cartridge replacement time display member, and thus are connected by a portion other than the gripping portion of the fitting groove forming portion. Furthermore, "the side of the gripping portion of the cartridge replacement time display member formed on the outer surface of the fitting groove forming portion on which the locking convex portion is formed when viewed from the fitting groove" is the cartridge replacement with both fingers It means the finger on the side on which the locking projection is formed when the time display member is picked. Here, the slit refers to a groove shape having an opening opened at one end.

  When the cartridge replacement time display member has the slit and the gripping portion as described above, the gripping portion on the side with the slit is easily elasticated by the pressing force of the finger when gripping both gripping portions with both fingers. Although deformed, almost no stress or deformation occurs in the portion where the locking convex portion or concave portion is present (the inner surface of the fitting groove forming portion). The reaction force is applied to the finger by the elastic deformation of the gripping portion, and a frictional force is generated between the finger and the gripping portion, so that the cartridge replacement time display member can be moved. In this way, the cartridge replacement timing display member is moved without receiving an excessive pressing stress that suppresses the deflection caused by the movement of the cartridge replacement timing display member in the portion where the locking convex portion or the concave portion exists. Become.

  In addition, as described above, the structure in which the slit is provided and one gripping portion is provided outside the slit is the reason why the shape of the cartridge replacement time display member is preferably E-shaped. The shape of the cartridge replacement time display member may be an S type in which the opening direction of the slit is opposite to the E type. However, the E-type is superior to the S-type in reducing the pressing stress on the portions where the locking convex portions or concave portions exist.

  Due to the structure of the cartridge replacement time display member as described above, when the gripping portion of the cartridge replacement time display member is gripped with a finger and moved in the longitudinal direction of the main body container handle, Since there is a space (slit) between the gripping part and the inner surface of the fitting groove forming part having a convex part or a concave part, and it does not suppress the deflection of the part that should be bent by movement, the wear of the convex part or concave part for locking As it is reduced and used, the fitting between the cartridge replacement time display member and the main body container handle becomes weak, and the problem that the position of the replacement time display member changes without permission can be prevented.

  The width of the slit 119 is preferably 2 mm or more. Thereby, the slit 119 can also be easily cleaned using a toothpick at home.

  Further, in the cartridge replacement time display member 111 of FIG. 12, the direction of gripping both gripping portions is substantially perpendicular to the longitudinal direction of the main body container handle 12.

  Another embodiment of the cartridge replacement time display member is shown in FIGS. FIGS. 16 and 17 are views of the same cartridge replacement time display member drawn from different angles. Also in FIG. 16, the cartridge replacement time display member includes a fitting groove forming portion formed so as to cover at least a part of the main body container handle, and a locking convex portion formed on the inner surface of the fitting groove forming portion. The cartridge replacement time display member formed on the outer surface of the fitting groove forming portion, and the holding portion on the side of the holding portion on which the locking convex portion is formed when viewed from the fitting groove. A slit is provided on a straight line connecting the projection and the concave portion for locking.
