Description

  The present invention relates to a pitcher type water purifier.

  Conventionally, a pitcher-type water purifier in which a water purification cartridge is detachably provided is known. This pitcher-type water purifier can maintain the purification performance by replacing it with a new water purification cartridge even if the purification performance deteriorates. More specifically, in the pitcher-type water purifier, a container for raw water is accommodated inside a container main body having a handle, and a water purification cartridge is attached to the bottom of the container for raw water. And the raw | natural water accommodated in the inside of a container via this water purification cartridge falls in a container main body, and is stored by purifying with dead weight. 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 container body with a handle. By tilting, only purified water is poured into the cup through the water inlet.

By the way, in recent years, further improvement in merchantability has been desired in the pitcher-type water purifier. For example, in order to establish an appropriate replacement cycle of the above-described water purification cartridge, opening and closing of the lid, that is, raw water would have been supplied. There is one that counts and displays the number of times (for example, see Patent Document 1).
Japanese National Patent Publication No. 10-50937

However, in the above-described conventional pitcher-type water purifier, since the lid is fitted and detachable, for example, if the container falls or an impact is applied to the container body for some reason, the lid is Although it is not, there is a problem that it may come off from the container body.
For this reason, when the water purification cartridge is replaced according to the counting result of the number of times of opening and closing the lid, the replacement timing of the water purification cartridge becomes higher than the timing at which the water purification cartridge should be originally replaced. On the other hand, if the lid and the container are more tightly fitted so that the lid does not easily come off the container body, the frequency of the lid coming off will decrease, but the lid will not easily come off, increasing the burden on the user during water supply etc. Resulting in.

  Therefore, the present invention provides a pitcher-type water purifier that prevents the lid from coming off due to an impact and can easily perform a water supply operation during water supply.

In order to solve the above-described problems, the invention described in claim 1 includes a container main body (for example, the container main body 2 in the embodiment) and an upper container (for example, implementation) that is detachably attached to the upper portion of the container main body. And a communication part (for example, the hole 13 in the embodiment) communicating with the lower part of the container main body in a part of the upper container, and a water purification filter (for example, In the pitcher type water purifier in which the water purification cartridge 14) according to the embodiment is detachably attached,
A lid member (for example, the lid 3 in the embodiment) for slidably opening and closing the opening is provided in the opening (for example, the opening 17 in the embodiment) of the container body.
The lid member can be positioned at two or more positions along the sliding direction.

  In the invention described in claim 2, in the invention described in claim 1, the lid member can be positioned at a position where at least only the water purification outlet (for example, the water injection port 10 in the embodiment) of the container body is opened. It is characterized by being.

  The invention described in claim 3 is characterized in that, in the invention described in claim 1 or 2, it is provided with counting means for counting the number of times of water supply (for example, the counter 40 in the embodiment).

  The invention described in claim 4 is the invention described in claim 3, wherein the counting means detects at least an opening operation of the lid member for supplying water and a closing operation of the lid member after supplying water. When both the opening operation and the closing operation are detected, it is counted as one water supply.

According to the first aspect of the present invention, since the lid member is slidably provided in the opening of the container main body, it is possible to suppress the detachment from the container main body due to an impact rather than a conventional fitting-type lid. In addition, there is an effect that the opening can be easily opened by sliding the lid member when pouring purified water or supplying raw water.
Further, since the lid member can be positioned at at least two positions, it is possible to prevent the lid member from sliding and moving when unnecessary.

  According to the invention described in claim 2, since the lid member can be positioned at a position where only the water purification outlet of the container body is opened during the opening operation and the closing operation of the lid member, the raw water can be easily purified without leaking. The effect is that only can be poured.

According to invention of Claim 3, since the appropriate replacement cycle of a water purifying filter can be confirmed by providing the counting means which counts the frequency | count of water supply, the replacement | exchange of an unnecessary water purifying filter is suppressed. There is an effect that can be.
In addition, since the opening and closing of the lid member slidably provided by the counting means is counted, the counting due to inadvertent opening is reduced and the reliability of the counting result is improved as compared with the case of a conventional fitting-type lid. There is an effect of doing.

  According to the invention described in claim 4, when both the opening operation for water supply and the closing operation after water supply are detected, the water is counted as one water supply. For example, by a small slide such as vibration Since the erroneous counting can be suppressed, there is an effect that the reliability of the counting result by the counting means can be further improved.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.
In FIG. 1, the code | symbol 1 has shown the pitcher type water purifier in embodiment of this invention. This pitcher-type water purifier 1 is mainly composed of a container body 2, a lid (lid member) 3, and a raw water tank (upper container) 4.

  The container body 2 is formed in a bottomed cylindrical shape including a bottom wall 5, a front wall 6, left and right side walls 7 and 7, and a rear wall 8. A handle 9 is integrally formed on the rear wall 8. Further, a water inlet 10 is formed on the front wall 6 opposite to the handle 9. And the corner | angular part between each of the front wall 6, the left and right side walls 7 and 7, and the rear wall 8 is formed in a curved surface, and it is not illustrated as a slip stopper on the bottom surface of the bottom wall 5 of the container body 2. A ring-shaped rubber is attached.

  The water injection port 10 is formed such that a substantially central portion in the left-right direction of the upper edge 11 of the front wall 6 projects in a mountain shape toward the front, and the upper edge 11 of the front wall 6 in which the water injection port 10 is formed. The amount of protrusion by the water injection port 10 gradually decreases from the bottom to the bottom, and is formed so as to converge at the substantially vertical center of the container body 2 having a substantially rectangular cross section. By forming the water injection port 10 in this way, a passage leading to the lower portion 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, purified water stored in the lower part of the container body 2 is poured into an external container or the like through the passage.

  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. The outer side of the upper edges of the left and right side walls 7, 7 extends along the upper edge. Rails R and R are formed respectively. The rails R, R have a substantially bowl-shaped cross section that protrudes outward from the top toward the bottom (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 edge of the left and right side walls. By forming this notch 7a, the container body 2 is detachably accommodated. Since the upper edge can be easily grasped at the time of removal of the raw water tank 4, the raw water tank 4 can be easily removed.

  The raw water tank 4 is formed in a bottomed cylindrical shape having a substantially rectangular cross section with a corner formed by a curved surface, and a hole (communication portion) 13 communicating with the lower portion of the container body 2 is formed in the bottom wall 12. 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 so that the water purification cartridge 14 protrudes downward from the bottom wall 12 in an attached state. It has become. Here, the water purification cartridge 14 has a raw water inlet (not shown) communicating with the inside of the raw water tank 4 at an upper portion thereof, and a water outlet (not shown) communicating with the inside of the container body at a lower portion thereof. In the cylindrical passage between them, an adsorbent such as activated carbon and a filter such as a hollow fiber membrane are provided, and the raw water flowing in from the raw water inlet flows through the passage in the water purification cartridge 14 by its own weight. As purified water, it is discharged downward from the purified water outlet.

  A flange 16 is formed on the periphery of the opening 15 of the raw water tank 4 so as to be bent at a substantially right angle toward the outside. When the raw water tank 4 is inserted from the opening 17 of the container body 2, this collar 16 is caught by the peripheral part of the opening part 17 of the container main body 2, and the raw | natural water tank 4 is fixed to the upper part of the container main body 2. As shown in FIG.

  In addition, a partition wall 18 is formed on the front side of the periphery of the opening 15 of the raw water tank 4 so as to continue to the collar portion 16 and extend forward. The partition wall 18 separates the interior of the raw water tank 4 from the water inlet 10 of the container body 2 together with a packing 19 (see FIG. 3) of the lid 3 to be described later, and its upper surface is smooth and pressed by the packing 19. It is a surface.

  And, as shown in FIG. 4, the raw water tank 4 is accommodated in the container main body 2 at the front edge 20 of the partition wall 18 from the right and left sides slightly along the upper edge 11 of the front wall 6. After forming to the position where it entered, the recessed parts 21 and 21 which are spaced apart from the upper edge 11 and are immersed in the shape of a mortar toward the back are formed. 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 and 21 and protrudes forward with substantially the same shape as the upper edge 11. Here, the upper edge 11 of the front wall 6 and the convex portion 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 is slidable in the front-rear direction by the rails R and R described above.

  The lid 3 is formed so as to protrude downward from the left side edge, the right side edge and the rear side edge of the main plate part 30, and the left and right side walls 7 and 7 and the rear wall (see FIG. 1) of the main body 2. Left and right side walls 31, 31 (only the left side wall 31 is shown in the figure for the sake of illustration) and a rear wall (not shown) surrounding the upper edge of the main plate part 30 and extending forward. The front plate portion 33 is formed to correspond to the outer shape of the water inlet 10 of the container body 2 described above.

  The main plate portion 30 has an inclined surface 34 that is inclined from the front toward the rear lower side at the center thereof, and the rear portion of the inclined surface 34 is submerged from the peripheral edge 35 to form a recess 36. The recess 36 functions as a so-called handle, and the user can easily slide the lid 3 in the opening direction, that is, backward 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 protruding 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. . Here, by inserting the above-described rail R and collar portion 16 laminated in the recess 38, the lid 3 is slid forward along the rail R from the rear of the container body 2 and attached to the container body 2. The protrusion 37 is caught by the lower part of the rail R, and the direction in which the lid 3 peels from the container body 2, that is, the upward movement is restricted.

  Here, the lid 3 is formed 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 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, whereby a seal between the lid 3 and the raw water tank is formed. In addition, although the case where the packing 19 was made into the different body was demonstrated, you may integrally form with the lid 3 and provide.

  As shown in FIG. 4, the front plate portion 33 mainly opens and closes the opening portion 23 of the water injection port 10, and is formed to extend forward and continue to the main plate portion 30 described above. The shape 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 ridge 39 protruding downward is integrally formed on the peripheral edge of the front plate portion 33.

  A rear wall (not shown) extending downward from the rear edge of the main plate portion 30 is an outer surface of the rear wall 8 of the opening 17 of the container body 2 when the lid 3 is slid forward more than necessary. The frontmost position of the lid 3 is positioned by the rear wall.

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

  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 where the opening 17 is completely closed. Positioned at a position where only the opening 23 of the water inlet 10 is opened and the front edge of the front plate portion 33 of the lid 3 and the front edge of the convex portion 22 of the partition wall 18 overlap each other, which is a water injection position for pouring the purified water shown in FIG. Is done.

  Here, the positioning at the water injection position indicates that a moderation feeling can be obtained at the water injection position when the lid 3 is slid. As a mechanism for performing this positioning, it is sufficient that a sense of moderation is obtained. For example, a protrusion or hole (not shown) is provided in the lid 3, while a hole or hole (not shown) corresponding to the protrusion or hole of the lid 3 is provided in the container body 2. What is necessary is just to comprise so that a protrusion and the hole corresponding to this protrusion may be fitted in the above-mentioned water pouring position. 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.

  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 is rapidly increased and positioned. It will not open. When the lid 3 is slid with a larger force and further opened, the increased sliding force is reduced to the same level as before the increase, and when the lid 3 is slid in the opening direction as shown in FIG. Is detached from the container body 2. Note that the positioning of the lid 3 is not limited to the two positions of the water pouring position and the closing position, and for example, the lid 3 may be positioned at a position in the middle of removing the lid 3 from the container body 2 as shown in FIG. In this way, when positioning is performed in the middle of removal, it is possible to prevent the lid 3 from dropping by sliding freely from the water injection position for some reason.

By the way, it is preferable that the above-described water purification cartridge 14 be replaced when the amount of filtered raw water reaches a predetermined amount without waste. However, if the amount of raw water is to be integrated, the component configuration becomes complicated and the cost becomes high. Therefore, the replacement timing of the water purification cartridge 14 is generally determined based on the usage period 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 embodiment of the present invention, a counter 40 is incorporated in the lid 3 to count the number of times the lid 3 is opened and closed, and to indicate a guideline for replacing the water purification cartridge 14.

  As shown in FIG. 1, a display unit 41 that displays the number of times and an operation switch 42 that performs operations such as resetting the counting result of the display unit 41 are provided on the upper surface of the counter 40. And an operation switch 42 are exposed on the upper surface of the main plate portion 30 of the lid 3. On the other hand, as shown in FIG. 4, a tunnel-shaped accommodation portion 44 is formed in the rear wall 43 of the raw water tank 4 along the vertical direction thereof. 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.

  The counter 40 is provided with a sensor (not shown) for detecting a permanent magnet on the lower surface side of the lid 3 so that the permanent magnet passes under the sensor to detect that the permanent magnet has passed once. It has become. 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 about half, that is, the raw water tank 4 is sufficiently supplied with water. When the lid 3 is opened to a position where water can be supplied, the permanent magnet is detected once by the sensor. Therefore, the sensor detects the permanent magnet as long as the lid 3 passes the water supplyable position in any of the method of removing the lid 3 and performing the water supply operation 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 opened, and may be set to an appropriate position where the lid 3 is sufficiently opened from the water injection position.

  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 magnet passes under the sensor, the counter 40 detects this passage as one pass.

  That is, when supplying water into the raw water tank 4, the lid 3 is opened as much 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 40 is reset twice. When the two passages are detected, the counter 40 determines that one water supply has been performed and performs one count. 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 as the predetermined number of times. The water purification cartridge 14 will be replaced when the value reaches.

  Therefore, according to the above-described embodiment, the lid 3 is provided so as to be slidable with respect to the container main body 2, so that the lid 3 is less likely to come off in the peeling direction due to impact compared to a conventional fitting-type lid. Furthermore, when pouring clean water or supplying raw water, the lid 3 can be slid to easily open the opening 17.

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.
Since the lid 3 can be positioned at a position where only the water injection port 10 of the container body 2 is opened when the lid 3 is opened and closed, 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.

Further, since the counter 3 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 timing of the water purification cartridge 14, and therefore, unnecessary replacement of the water purification cartridge 14 can be suppressed.
In addition, compared with the conventional lid, it is possible to reduce the count of the lid 3 that is slidably provided, such as an impact, so that the counting result by the counter 40 is improved. Can be made.

  And since it counts as one water supply when both the opening operation | movement for water supply of the lid 3 and the closing operation | movement after water supply are detected, it may be erroneously counted by the small amount of slides by vibration etc. As a result, the reliability of the counting result of the counter 40 can be improved, and the replacement cycle of the water purification cartridge 14 can be recognized more accurately.

In the above-described embodiment, the configuration is such that the opening and closing of the lid 3 is detected magnetically by using a permanent magnet and the number of times of water supply is counted. However, the lid 3 is opened once and closed once. For example, it may be configured to count mechanically. More specifically, a projection is provided at a position where a permanent magnet is provided, and the dial is touched twice by this contact. You may comprise so that it can count by rotating. 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 one location. Further, a permanent magnet may be attached to the lid 3 and the counter 40 may be provided on the container body 2.
The position of the foremost position of the lid 3 has been described as being formed by the stepped portion B and the rear wall. However, a moderation feeling may be imparted at the closed position of the lid 3.
