Background art

Conventionally, a pitcher type water purifier having a water purification cartridge for purifying water is known. In this pitcher type water purifier, the water purification cartridge is detachable, so if the purification performance deteriorates, it can be maintained by replacing it with a new water purification cartridge. More specifically, in the pitcher type water purifier, a container for raw water is accommodated inside a container body provided with a handle, and a water purification cartridge is attached to the bottom of the container for raw water. The raw water stored in the container through the water purification cartridge falls into the container body while being purified by its own weight, and is stored. In addition, the container body is provided with a water inlet for pouring purified water into a cup and the like, and a lid that opens and closes the opening of the container body excluding the water inlet, and the user holds the handle. By tilting the container body, only purified water is poured into the cup through the water inlet.

[0003] In recent years, it has been desired that the pitcher-type water purifier be further improved in merchantability. For example, in order to replace the above-described water purification cartridge in an appropriate replacement cycle without waste, the lid is opened, that is, the raw water is removed. It counts and displays the number of times that water would have been supplied (for example, see Patent Document 1).

In Fig. 6, the amount of protrusion from the water inlet 10 gradually decreases from the upper edge 11 downward, and converges at a substantially central portion in the vertical direction of the container body 2 having a substantially rectangular cross section. To do Is formed. By forming the water injection port 10 in this way, a passage leading to the lower part of the container body 2 is formed between the front wall 6 and the raw water tank 4 (details will be described later), and a pitcher type holding the handle 9 By tilting the water purifier 1 toward the water inlet 10 side, the purified water stored in the lower part of the container body 2 is poured into an external container through the passage.

[0029] As shown in Fig. 2, the container body 2 has upper edges of the left and right side walls 7, 7 formed in parallel to each other. Rails R and R are formed along the edges. The rails R and R are formed so as to protrude outward from the upper part to the lower part, and the cross section is substantially bowl-shaped (see Fig. 3). In addition, a mortar-shaped notch 7a is provided at a substantially central portion in the front-rear direction of the upper edges of the left and right side walls, and the notch 7a is formed so that the upper part of the container body 2 is detachable. Since the upper edge of the raw water tank 4 accommodated in the container can be easily grasped when the raw water tank 4 is removed, the raw water tank 4 can be easily removed.

[0030] The raw water tank 4 is formed in a bottomed cylindrical shape having a curved corner portion and a substantially rectangular cross-sectional shape, and the bottom wall 12 has a hole communicating with the lower portion of the container body 2. (Communication part) 13 is formed. A cylindrical water purification cartridge (water purification filter) 14 is detachably provided in the hole 13 from the inside of the raw water tank 4, and the water purification cartridge 14 projects downward from the bottom wall 12 in an attached state. It is like that. Here, the water purification cartridge 14 is provided with a raw water inlet (not shown) communicating with the inside of the raw water tank 4 at an upper portion thereof, and with a water purification outlet (not shown) communicating with the inside of the container body at a lower portion thereof. An adsorbent such as activated carbon and a filter such as a hollow fiber membrane are provided in the cylindrical passage between the outlet and the raw water flowing from the raw water inlet flows through the passage in the water purification cartridge 14 by its own weight. Then, it is discharged as purified water below the purified water outlet force.

[0031] On the periphery of the opening 15 of the raw water tank 4, there is provided a collar portion 16 bent at a substantially right angle toward the outside. When the raw water tank 4 is inserted through the opening 17 of the container body 2, The collar portion 16 has a pulling force on the peripheral portion of the opening 17 of the container body 2, and the raw water tank 4 is fixed to the upper portion of the container body 2.

In addition, a partition wall 18 is formed on the front side of the peripheral edge of the opening 15 of the raw water tank 4 so as to continue to the collar portion 16 and extend forward. This partition wall 18 is a package of the lid 3 described later. 19 (see FIG. 3) and the interior of the raw water tank 4 and the water inlet 10 of the container body 2 are separated, and the upper surface thereof is a smooth surface pressed by the packing 19.

[0033] Then, the raw water tank 4 is accommodated in the container body 2 at the front edge 20 of the partition wall 18 as shown in FIG. Recesses 21, 21 are formed that are formed to a position slightly inward along 11, and then sink away in a mortar shape away from the upper edge 11. A convex portion 22 is formed at a substantially central position in the left-right direction of the front edge 20 sandwiched between the concave portions 21, 21 and protrudes forward in the same shape as the outer shape of the upper edge 11. . Here, the upper edge 11 of the front wall 6 and the protrusion 22 are spaced apart from each other, and this space constitutes the opening 23 of the water inlet 10.

On the other hand, the container body 2 is detachably provided with a lid 3 that opens and closes the opening 17, and the lid 3 can be slid in the front-rear direction by the rails R and R described above.

[0035] The lid 3 is formed so as to protrude downward from the left, right and rear edges of the main plate 30 and the left and right side walls 7 and 7 of the container body 2 and the rear wall (FIG. 1). The left and right side walls 31, 31 (only the left side wall 31 is shown in the figure for illustration purposes) and the rear wall (not shown), and the front of the main plate 30. The front plate portion 33 corresponding to the outer shape of the water inlet 10 of the container body 2 described above is formed in a continuous manner and extending forward.

[0036] The main plate portion 30 has an inclined surface 34 that is inclined from the front toward the rear lower side at the central portion thereof, and the rear portion of the inclined surface 34 is submerged from the peripheral edge 35 to form a recess 36. Yes. The recess 36 functions as a so-called handle, and the user can easily slide the lid 3 in the opening direction, that is, rearward by hooking a finger on the recess 36.

As shown in FIG. 3, the left and right walls 31, 31 extending downward from the left and right edges of the main plate portion 30 are formed with ridges 37 projecting inward from the lower edges. . The protrusion 37, the left and right side walls 31, 31 and the main plate portion 30 constitute a concave portion 38 having a substantially U-shaped cross section, and the substantially U-shaped concave portion 38 functions as a groove. It has become. Here, the above-described laminated portion of the rail R and the flange portion 16 is inserted into the concave portion 38, and the lid 3 is slid forward along the rail R from the rear side of the container body 2 to the container body 2. When attached, the protrusion 37 is pulled under the rail R, and the movement of the lid 3 in the direction of peeling from the container body 2, that is, the upward movement is restricted. [0038] Here, the lid 3 extends along the right and left side edges and the rear side edge of the main plate portion 30 and at a position slightly inside the protrusion 39 (described later) formed on the peripheral edge of the front plate portion 33. A packing 19 formed in a ring shape along the ridge 39 is attached, and the packing 19 is sandwiched between the main plate portion 30 and the flange portion 16 described above. The packing 19 is sandwiched between the main plate portion 30 and the flange portion 16 so that a seal is formed between the lid 3 and the raw water tank. In addition, although the case where the knot 19 is separated is described, it may be formed integrally with the lid 3.

[0039] As shown in FIG. 4, the front plate portion 33 mainly opens and closes the opening 23 of the water inlet 10, and is formed to extend forward and continue to the main plate portion 30 described above. The shape on the front end side is formed so as to correspond to the shape of the water inlet 10 described above, that is, the shape of the front portion of the opening 17. Further, a protrusion 39 protruding downward is formed on the periphery of the front plate portion 33 in a body-like manner.

[0040] Further, a rear wall (not shown) extending downward from the rear edge of the main plate portion 30 is provided behind the opening 17 of the container body 2 when the lid 3 is slid forward more than necessary. The outer wall of the wall 8 is brought into contact with the outer surface, and the foremost position of the lid 3 is positioned by the rear wall.

[0041] On the other hand, the opening 17 of the container body 2 has a stepped front portion at the periphery, and the vertical surface of the stepped stepped portion B (see FIG. 2) is arranged perpendicular to the rail R. Has been. That is, when the lid 3 is slid in the closing direction, that is, forward, the front ends of the left and right side walls 31, 31 of the lid 3 abut against the vertical surface of the stepped portion B and cannot slide forward any more. As with the rear wall of the lid 3, the foremost position of the lid 3 is positioned.

[0042] Further, the lid 3 described above is configured to be positioned at a position other than the above by sliding operation. More specifically, as shown in FIG. 1, the lid 3 is first positioned at a closed position in which the opening 17 is completely closed. Positioned at the position where only the opening 23 of the water inlet 10 is opened and the front edge of the front plate 33 of the lid 3 and the front edge of the convex part 22 of the partition wall 18 overlap each other, which is the water injection position for pouring the purified water shown in Fig. 5. Is done.

[0043] Here, the positioning at the water injection position means that when the lid 3 is slid, the water injection position is This indicates that a feeling of moderation (responsibility that the lid 3 temporarily stops) can be obtained. As a mechanism for performing this positioning, it is sufficient that a sense of moderation is obtained.For example, a protrusion or a hole (not shown) is provided on the lid 3, while a container body 2 is not shown corresponding to the protrusion or hole of the lid 3. A hole or a protrusion may be provided, and the protrusion and the hole corresponding to the protrusion may be configured to fit at the above-described water injection position. In addition, the said hole may provide a bulge in the container main body 2 or the lid | cover 3, and may be provided in the approximate top part of the bulge. Further, the protrusion may be provided so as to be able to appear and retract and may be urged in the protruding direction by an elastic member.

[0044] By positioning in this way, when the lid 3 is slid from the closed state and opened, the force to slide at the water injection position shown in Fig. 5 increases rapidly and is not slid with a larger force. And no more open operation. When the lid 3 is further opened by sliding the lid 3 with a larger force, the increased sliding force decreases to the level before the increase, and when it is slid in the opening direction as shown in FIG. The lid 3 will be detached from the container body 2. Note that the positioning of the lid 3 is not limited to the two positions of the water injection position and the clogging position.For example, as shown in Fig. 6, the lid 3 may be positioned at a position where it is being removed from the container body 2! /. In this way, when positioning is performed during removal, the force S can be used to prevent the lid 3 from sliding off for some reason from the pouring position for any reason.

By the way, it is preferable that the above-described water purification cartridge 14 be replaced when the amount of the filtered raw water reaches a predetermined amount, but it is preferable that the amount of the raw water is added. Become high. Therefore, the replacement timing of the water purification cartridge 14 is generally determined based on the period of use of the water purification cartridge and the number of times the raw water is supplied.

In the pitcher-type water purifier 1 according to the first embodiment of the present invention, a counter 40 is built in the lid 3 to count the number of times the lid 3 is opened and closed and to indicate a replacement timing of the water purification cartridge 14.

[0046] As shown in FIG. 1, on the upper surface of the counter 40, a display unit 41 for displaying the number of times and an operation switch 42 for performing operations such as resetting the counting result of the display unit 41 are provided. A display section 41 and an operation switch 42 are provided exposed on the upper surface of the main plate section 30 of the lid 3. On the other hand, as shown in FIG. 4, the rear wall 43 of the raw water tank 4 is A tunnel-shaped accommodation portion 44 is formed. A permanent magnet (not shown) is accommodated in the accommodating portion 44, and the upper opening of the accommodating portion 44 is closed by a lid 45 in a state where the permanent magnet is accommodated.

[0047] The counter 40 is provided with a sensor (not shown) for detecting a permanent magnet on the lower surface side of the lid 3, and it is detected that the permanent magnet has passed once because the permanent magnet crosses below the sensor. It comes to put out. More specifically, when the lid 3 is slid from the closed position of the lid 3 shown in FIG. 1 and the water injection position shown in FIG. 5 to open the opening 17 by about half, that is, the water supply to the raw water tank 4 is sufficient. The permanent magnet is detected once by the sensor when the lid 3 is opened to the position where water can be supplied. Therefore, the sensor detects a permanent magnet as long as the lid 3 passes the water supplyable position, regardless of the method of performing the water supply operation with the lid 3 removed and the method of performing the water supply operation without removing the lid 3. It becomes. Note that the water supply possible position is not limited to the position where the opening 17 is half open, but may be set to an appropriate position where the lid 3 is sufficiently opened from the water injection position.

[0048] On the other hand, when the lid 3 shown in FIG. 4 is removed or when the water supply position shown in FIG. 6 is returned to the water pouring position shown in FIG. 5 and the closed position shown in FIG. Since the permanent magnet passes below the sensor from the direction, the counter 40 detects this passage as one pass.

[0049] That is, when supplying water into the raw water tank 4, the lid 3 is fully opened as necessary to perform the water supply operation, and when the water supply operation is completed and returned to the water injection position or the closed position, the counter 1 Will detect the passage of two permanent magnets in total, and the counter 40 is configured to perform one counting by determining that one water supply has been performed when the two passages are detected. ing. Here, the number of times of water supply is determined for the water purification cartridge 14 as a guideline for replacement in advance, and the user of the pitcher-type water purifier 1 determines the number of times counted by the counter 40 in advance. The water purification cartridge 14 will be replaced when the number of times is reached.

[0050] Therefore, according to the above-described first embodiment, the lid 3 is provided so as to be slidable with respect to the container body 2, so that the lid 3 is affected by an impact compared to a conventional fitting-type lid. It becomes difficult to come off in the peeling direction, and when the purified water is poured or when the raw water is supplied, the lid 17 can be slid to easily open the opening 17.

[0051] Further, since the lid 3 can be positioned at at least two positions, it is possible to prevent the lid 3 from sliding and moving when unnecessary.

When the lid 3 is opened and closed, the lid 3 can be positioned at a position where only the water inlet 10 of the container body 2 is opened, so that the raw water in the raw water tank 4 does not leak to the outside. Only the purified water stored in can be poured easily.

[0052] Furthermore, since the counter 40 for counting the number of times of water supply is built in the lid 3, it is possible to check the guideline for the replacement time of the water purification cartridge 14, thereby suppressing unnecessary replacement of the water purification cartridge 14. can do.

Compared with conventional lids, the lid 3 provided slidably reduces the chances of accidental opening and counting, which improves the reliability of the counter 40 counting results. Can be made.

[0053] When both the opening operation for supplying water to the lid 3 and the closing operation after supplying water are detected

Since counting is performed as a single water supply, it is possible to improve the reliability of the counting result of the counter 40 and more accurately the water purification cartridge. The exchange cycle can be recognized.

[0054] In the first embodiment described above, the opening and closing operation of the force lid 3 configured to detect the opening and closing of the lid 3 magnetically using a permanent magnet and count the number of times of water supply is closed once. It is sufficient if the detection can be performed once in operation.For example, it may be configured to count mechanically.

Alternatively, a protrusion may be provided at a position where the permanent magnet is provided, and the dial may be rotated by two touches on the protrusion so that counting can be performed. Moreover, what is detected by direct contact may be electrically processed and displayed.

Furthermore, the permanent magnets described above may be provided at a plurality of locations instead of a single location. Alternatively, a permanent magnet may be attached to the lid 3 and the counter 40 may be provided on the container body 2. In addition, it has been described that the position of the foremost position of the lid 3 is made by the stepped portion B and the rear wall. However, a moderation feeling may be imparted at the closed position of the lid 3.

Hereinafter, a second embodiment of the present invention will be described with reference to FIGS. In FIG. 7, reference numeral 101 denotes a pitcher type water purifier according to the second embodiment of the present invention. This pitcher type water purifier 101 is mainly composed of a container body 102 and a lid 103 and an upper container 104 which is a so-called raw water tank.

[0056] The container body 102 is formed into a bottomed cylindrical shape including the bottom wall 105, the front wall 106, the left and right walls 107, 107 and the rear wall 108, and a handle 109 is formed on the rear wall 108. The water inlet 110 is formed on the front wall 106 opposite to the handle 109. The corners between the front wall 106, the left and right side walls 107, 107, and the rear wall 108 are formed with curved surfaces, and the bottom surface 105 of the bottom wall 105 of the container body 102 slides at least partially.

[0057] The water inlet 110 is formed such that a substantially central portion in the left-right direction of the upper edge 111 of the front wall 106 is directed forward and thus protrudes in a mountain shape, and the front wall on which the water inlet 110 is formed. In 106, the amount of protrusion from the water injection port 110 gradually decreases toward the downward direction from the upper edge 111, and converges at a substantially central portion in the vertical direction of the container body 102 having a substantially rectangular cross section. It is formed as follows. By forming the water injection port 110 in this way, a passage leading to the lower part of the container body 102 is formed between the front wall 106 and the upper container 104 (details will be described later), and a pitcher type holding the handle 109 is formed. By tilting the water purifier 101 toward the water inlet 110, the purified water stored in the lower part of the container body 102 is poured into an external container or the like through the passage.

[0058] As shown in FIG. 8, the container body 102 has upper edges of the left and right side walls 107, 107 formed in parallel to each other. Rails R 'and R' are formed along the line. The rails R ′ and R ′ are formed to protrude outward from the upper part to the lower part, and the cross-sectional shape is substantially bowl-shaped (see Fig. 9). In addition, a mortar-shaped notch 107a is provided at a substantially central portion in the front-rear direction of the upper edges of the left and right side walls. Since the upper edge of the upper container 104 that is freely accommodated can be easily grasped, the upper container 104 can be easily removed.

[0059] The upper container 104 is formed in a bottomed cylindrical shape whose corners are curved and the cross-sectional shape is substantially rectangular, and the bottom wall 112 is a hole communicating with the lower part of the container body 102. A communication part 113 is formed. In addition, a cylindrical water purification cartridge 114 is detachably provided from the inner side of the upper container 104 in the communication portion 113, and the water purification cartridge 114 protrudes downward from the bottom wall 112 in the attached state. ing. Here, the water purification cartridge 114 is provided with a raw water inlet (not shown) communicating with the inside of the upper container 104 at an upper portion thereof, and with a water purification outlet (not shown) communicating with the inside of the container main body at a lower portion thereof. In the cylindrical passage between the two, an adsorbent such as activated carbon and a filter such as a hollow fiber membrane are provided, and the raw water flowing from the raw water inlet flows through the passage in the water purification cartridge 114 due to its own weight. The water is then discharged downward as purified water.

[0060] On the periphery of the opening 115 of the upper container 104, a collar portion 116 formed to be bent at a substantially right angle toward the outside is provided, and the upper container 104 is inserted through the opening 117 of the container body 102. As a result, the collar 116 pulls the peripheral edge of the opening 117 of the container main body 102, and the lifting container 104 is fixed to the upper portion of the container main body 102.

In addition, a partition wall 118 is formed on the front side of the peripheral edge of the opening 115 of the upper container 104 so as to continue to the flange portion 116 and extend forward. The partition wall 118 separates the inner part of the upper container 104 from the water injection port 110 of the container body 102.

[0062] Then, as shown in FIG. 10, the upper edge 104 of the partition wall 118 has the upper container 104 accommodated in the container main body 102. Recesses 121, 121 are formed which are formed to a position slightly inward along 111, and then sag in a bowl shape away from the upper edge 111. A convex portion 122 that is formed in substantially the same shape as the outer shape of the left and right center of the upper edge 111 and protrudes forward is provided at the approximate center in the left and right direction of the front edge 120 sandwiched between the recesses 121 and 121. It has been. The upper edge 111 of the front wall 106 and the convex portion 122 are spaced apart from each other, and this space constitutes the opening 123 of the water inlet 110.

[0063] On the other hand, a lid 103 for opening and closing the opening 117 is detachably provided on the container body 102, and the lid 103 is slidable in the front-rear direction by the rails R 'and R' described above.

[0064] The lid 103 is formed so as to protrude downward from the left, right and rear edges of the main plate 130 and the left and right side walls 107, 107 and the rear wall (see FIG. 7) The left and right side walls 131, 131 (only the left side wall 131 is shown in the figure for the sake of illustration) and the rear wall (not shown) that surround the upper edge of the main plate 130 and the front part of the main plate part 130 The front plate portion 133 is formed to extend and correspond to the outer shape of the water inlet 110 of the container body 102 described above.

[0065] The main plate portion 130 has an inclined surface 134 that is inclined from the front toward the rear lower side at the center portion thereof, and the rear portion of the inclined surface 134 is submerged from the peripheral edge 135 to form a recess 136. The The recess 136 functions as a so-called handle, and the user can easily slide the lid 103 in the opening direction, that is, rearward by hooking a finger on the recess 136.

As shown in FIG. 9, the left side of the main plate portion 130 extends downward from the right side edge. The right side walls 131, 131 are formed with protrusions 137 projecting inward from the lower edge thereof. . The protrusion 137, the left and right side walls 131, 131, and the main plate portion 130 constitute a concave portion 138 having a substantially U-shaped cross section, and the substantially U-shaped concave portion 138 functions as a groove. It has become. Here, the recess 138 is inserted with the above-described laminated layer of the rail R ′ and the collar portion 116, and the lid 103 is slid forward from the rear of the container body 102 along the rail R ′ to move the container body. When attached to 102, the protrusion 137 is pulled to the lower part of the rail R ′, and the force of the container 103 of the lid 103 from being peeled, that is, the upward movement is restricted.

[0067] As shown in FIG. 10, the front plate portion 133 mainly opens and closes the opening portion 123 of the water injection port 110. The front plate portion 133 is connected to the main plate portion 130 described above and extends forward, The shape on the tip side is formed so as to correspond to the shape of the water injection port 110 described above, that is, the shape of the front portion of the opening 117. Further, a protrusion 139 protruding downward is formed on the periphery of the front plate portion 133.

[0068] Further, a rear wall (not shown) extending downward from the rear edge of the main plate portion 130 is a rear wall of the opening 117 of the container body 102 when the lid 103 is slid forward more than necessary. The front wall of the lid 103 is positioned by the rear wall.

[0069] On the other hand, the front part of the peripheral edge of the opening 117 of the container body 102 is stepped, and the vertical surface of the stepped portion B ′ (see FIG. 8) is perpendicular to the rail R ′. Are arranged. sand In other words, when the lid 103 is slid in the closing direction, that is, forward, the front ends of the left and right side walls 131, 131 of the lid 103 abut against the vertical surface of the stepped portion B 'and cannot slide forward any further. Thus, the frontmost position of the lid 103 is positioned in the same manner as the rear wall of the lid 103 described above.

[0070] Further, the above-described lid 103 is configured to be positioned at a position other than the above by sliding operation. More specifically, as shown in FIG. 7, the lid 103 is first positioned at a closed position where the opening 117 is completely closed, and when it is slid backward from this position, that is, in the opening direction. 11, where only the opening 123 of the water inlet 110 is opened, and the front edge of the front plate portion 133 of the lid 103 and the front edge of the convex portion 122 of the partition wall 118 overlap each other. Positioned with.

[0071] Here, the positioning at the water injection position means that when the lid 103 is slid, a feeling of moderation (a response that the lid 103 temporarily stops with a force) can be obtained at the water injection position. Is shown. As a mechanism for this positioning, a moderation feeling may be obtained. For example, a lid or hole (not shown) is provided in the lid 103, while a hole or hole (not shown) corresponding to the protrusion or hole of the lid 103 is provided in the container body 102. A protrusion may be provided, and the protrusion and the hole corresponding to the protrusion may be configured to fit at the water injection position described above. In addition, the hole may be provided in the container body 102 or the lid 103 and provided in a substantially top portion of the bulge. Further, the protrusion may be provided so as to be able to appear and retract, and the protrusion may be urged by an elastic member.

[0072] By positioning in this way, when the lid 103 is slid from the closed state and opened, the force to slide at the water injection position shown in FIG. 11 increases rapidly, and the slide is moved with a larger force. Otherwise, it will not open any more. When the lid 103 is slid with a larger force and further opened, the increased sliding force decreases to the same level as before the increase, and when the lid 103 is slid in the opening direction as shown in FIG. 103 is detached from the container body 102. Note that the positioning of the lid 103 is not limited to the water injection position or the closing position 102. For example, as shown in FIG. 12, the lid 103 may be positioned in the middle of removal from the container body 102. If positioning is performed during removal in this way, the lid will slide freely from the water injection position for some reason. 103 can be prevented from falling off.

By the way, as shown in FIG. 7, the above-mentioned lid 103 of the water purification cartridge 114 has a digital display type counter 140 that counts the number of times the lid 103 is opened and indicates a guideline for replacement timing of the water purification cartridge 114. Is provided. Here, the counter 140 is an electric counter driven by a button-type or coin-type alkaline battery or lithium battery.

Specifically, as shown in FIG. 13, the counter 140 is formed in a thin plate shape, and a display unit 141 and an operation switch 142 are arranged on the upper surface thereof. The counter 140 is a so-called subtraction counter that decrements the number displayed on the display unit 141 by depressing the operation switch 142 once in accordance with the addition of purified water to the water inlet 110. It functions as. Further, the counter 140 is configured such that the number displayed on the display unit 141 is reset to the initial value by long-pressing the operation switch 142 (for example, about 3 seconds). Here, the number of times of water supply, which is a guideline for the replacement timing, is determined in advance for the water purification cartridge 114, and the initial value of the counter 140 is set to the number of times of water supply of the water purification cartridge 114. In other words, the user of the pitcher-type water purifier 101 replaces the water purification cartridge 114 when the numerical force S “0” displayed on the display unit 141 of the counter 140 is reached.

In addition, the above-described counter 140 is pressed from above by the counter cover 143 and is detachably fixed to the lid 103. The counter cover 143 is formed in a substantially thin plate shape whose outer shape gradually widens from the front to the rear, and the display portion 141 and the operation switch 142 of the counter 140 are exposed on the lid 103 at the center. A window 1 43a is formed. The window 143a is formed to gradually widen from the front force toward the rear, like the outer shape of the counter cover 143. Further, the counter cover 143 is formed with claw-like locking portions 144 and 144 projecting forward and backward.

On the other hand, a concave portion 145 corresponding to the shape of the counter 140 is formed in the main plate portion 130 of the lid 103. Further, a stepped portion 146 is formed around the recessed portion 145 so as to be lowered by one step from the upper surface of the main plate portion 130 in a range corresponding to the outer shape of the counter cover 143. Further, at the front and rear positions of the step portion 146, the counter cover 1 described above is provided. Locking holes 147 and 147 for locking the 43 locking portions 144 and 144 are provided. Here, the force cover 143 can be made of a resin such as polypropylene or ABS resin. In particular, it is preferable to use the same resin as the resin forming the lid 103 for improving the appearance.

Yes

[0077] When the counter 140 is attached to the lid 103, the counter 140 is placed in the recess 145 of the lid 103, and then one of the locking portions 144 of the counter cover 143 is placed on one of the lids 103. Insert into the locking hole 147. Further, the other locking portion 144 is inserted into the other locking hole 147 while the counter cover 143 is slightly bent so as to protrude upward. Then, the shape of the counter cover 143 returns to the state before bending, and the locking portions 144 and 144 are locked in the locking holes 147 and 147 of the lid 3, respectively. Displacement is regulated. As a result, the counter 140 is pressed between the display unit 141 and the operation switch 142 from above by the counter cover 143, and is sandwiched between the counter cover 143 and the lid 103.

[0078] On the other hand, the removal procedure of the counter 140 may be performed in the reverse order of the above-described attachment. By pushing the locking portion 144 of the counter cover 143 from the locking hole 147 on the back side of the lid 103, the locking hole 147 Counter cover 143 comes off. Then, the counter cover 143 can be detached from the lid 103, and the counter 140 can be taken out from the recess 145. For example, a small groove may be provided on the left and right side surfaces of the counter cover 143 in order to make it easy to pull a nail or the like.

Therefore, according to the second embodiment described above, the counter 140 can count an appropriate replacement cycle of the water purification cartridge 114 that is detachably provided in the communication portion 113 of the upper container 104. Since the counter 140 is detachably provided on the lid 103, the counter 140 can be removed when the lid 103 is removed from the container body 102 for cleaning, for example.

[0080] Since the counter 140 can be removed from the lid 103, the lid 103 and the counter 140 can be separated and disposed of separately when disposing of them. Therefore, it is possible to dispose of the recyclable part as non-combustible waste. This can reduce the burden on the environment.

[0081] Furthermore, by providing a counter cover 143 for fixing the counter 140 to the lid 103, Appearance performance can be improved while detachably configuring the counter 140. In other words, regardless of the shape of the counter 140, the design around the force heater 140 can be easily changed by changing the shape of the counter cover 143.

[0082] Since the numerical value corresponding to the performance of the water purification cartridge 114 is displayed as the initial value in the counter 140, the initial setting of the counter 140 is facilitated, and an appropriate replacement cycle of the water purification power cartridge 114 is facilitated. Can be recognized.

[0083] Further, by using the counter 140 as a push button subtraction counter, for example, it is possible to prevent counting due to opening other than water supply, compared to the case of using a counter that automatically counts the number of times the lid 103 is opened. Therefore, the reliability of the count result is improved, and the water purification cartridge can be replaced with a more appropriate replacement cycle.

[0084] Furthermore, since the operation switch 142 is disposed slightly below the upper surface of the lid 103, it is possible to reduce erroneous operation of the operation switch 142.

In addition, the counter 140 is detachable so that it can be replaced with a new counter 140 when the L40 cannot be used.

In the second embodiment described above, the force described in the case of fixing the counter cover 143 to the lid 103 with the locking portions 144 and 144 is not limited to this as long as it can be easily fixed. . Further, the shape of the counter cover 143 is not limited to one that is directed from the front to the rear and gradually widened.

Further, when the force counter 140 described with respect to the case where the counter 140 is formed in a flat plate shape is not flat plate, the concave portion 145 corresponding to the shape may be provided in the lid.

[0086] Further, in the above-described embodiment, the case where the counter 140 is an electric type driven by a battery has been described! However, a mechanical counter may be used.

In the above-described embodiment, the case where the lid 103 is slidably provided has been described. However, the lid 103 is not limited to the sliding method as long as it can be opened and closed.

In the above-described embodiment, the case where the lid 103 and the main plate portion 130 are in direct contact with each other has been described. However, in order to prevent the lid 103 from cracking, for example, the main plate portion 130 of the lid 103 is connected to the main plate portion 130. Collar 1

It may be possible to interpose a packing between 16! Industrial applicability

According to the present invention, since the lid portion is slidably provided in the opening of the container body, it can be prevented from coming off from the container body due to an impact than the conventional fitting-type lid, and easily. The opening can be opened. In addition, since the lid can be positioned at at least two positions, the force S can be used to prevent the lid from sliding and moving when unnecessary.

In addition, since the counter can be removed from the lid, the lid and power counter can be separated and disposed separately when disposing of the counter, reducing the disposal of recyclable parts as incombustible waste. The burden on the environment can be reduced.
