Description

[Technical field]

[0001] The present invention relates to an installation kit for a pressure-resistant water purifier, an installation structure for a pressure-resistant water purifier, and a cartridge replacement method using the installation structure. [Background technology]

[0002] For example, water purifiers equipped with a water purification cartridge containing a filter medium are widely used as water purifiers that remove impurities such as chlorine contained in tap water. Since the filter medium contained in the water purification cartridge has a limited total amount of filtered water that can be processed, it is necessary to continue using the water purifier by periodically replacing the water purification cartridge.

[0003] There are two types of water purifiers: a water purifier that is connected to a water supply system and uses water pressure to supply tap water to a water purification cartridge, through which the purified water is passed, and then discharged. These water purifiers are available in a stop-at-source type and a stop-at-end type. The main stop system has a configuration in which the supply water passage to the water purifier is opened and closed to switch between discharging purified water and stopping the water flow, while the first stop system has a configuration in which the discharge water passage from the water purifier is opened and closed to switch between discharging purified water and stopping the water flow. Since the inside of a first-stop type water purifier is constantly pressurized by tap water pressure, the water purification cartridge is housed in a container with a pressure-resistant structure, and the device is also called a pressure-resistant water purifier.

[0004] Traditionally, pressure-resistant water purifiers were generally installed on the floor, but in recent years, wall-mounted installations have become more common in restaurants and other establishments, both for the sake of ease of use when disinfecting floors with hypochlorite, and to promote the installation of water purifiers. Patent Document 1 proposes a water purifier in which the water purification cartridge can be easily replaced while it is installed on a wall, in which the water purification cartridge can be attached and detached with one hand using a bayonet mechanism to a connecting member having a raw water inlet and a purified water outlet, the connecting member is fixed to the wall surface via a fixing member, and the connecting member is rotatable relative to the fixing member.

[0005] [Patent Document 1] International Publication No. 2016 / 056594 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the water purifier described in Patent Document 1 has insufficient pressure resistance because the water purification cartridge is attached and detached to the connecting part using a bayonet mechanism, and therefore cannot be applied to pressure-resistant water purifiers. In pressure-resistant water purifiers, fastening members are provided to make the joints of the container that houses the water purification cartridge pressure-resistant, and since it is necessary to use both hands to remove these fastening members, it is difficult for one person to perform the replacement work, especially when the device is installed on a wall. The present invention has been made in consideration of the above circumstances, and an object of the present invention is to make it possible to easily replace a water purification cartridge in a pressure-resistant water purifier installed on a wall surface.

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram showing an installation structure in which a pressure-resistant water purifier (hereinafter also simply referred to as a "water purifier") 1 is installed on a wall surface 7 using an installation kit for a pressure-resistant water purifier (hereinafter also simply referred to as an "installation kit") of this embodiment. The mounting kit of this embodiment includes an upper mounting fixture 10, a lower mounting fixture 20, and a body mounting fixture 30.

[0011] The water purifier 1 has a water purification cartridge (hereinafter also simply referred to as “cartridge”) 6 housed in a pressure-resistant container 5 . The pressure-resistant vessel 5 comprises a cylindrical vessel body 2 with a bottom, a vessel lid 3 which is detachably fitted into the opening of the vessel body 2, and a fastening member 4 which fastens the fitted portion between the vessel body 2 and the vessel lid 3. In this embodiment, the container body 2 is cylindrical with its central axis being axis P. A raw water inlet pipe 3a and a purified water outlet pipe 3b are provided on the upper surface of the container lid 3, protruding upward. The pipe axis Q of the raw water inlet pipe 3a is parallel to the axis P, and the purified water outlet pipe 3b is coaxial with the container body 2. The raw water inlet pipe 3a and the purified water outlet pipe 3b are provided with threads on their circumferential surfaces, and are configured to screw into a fixing nut 13. The container body 2 and the container lid 3 are made of, for example, stainless steel.

[0012] The fastening member 4 has a substantially circular belt portion 4a and a tightening portion 4b that tightens the belt portion 4a in a direction to reduce the diameter. The belt portion 4a has a groove 4d that accommodates the fitting portion of the container body 2 and the container lid 3, and is fitted with a rubber O-ring. Depending on the direction in which the handle 4c of the tightening portion 4b is turned, the belt portion 4a can be tightened in a direction to reduce the diameter or loosened in a direction to expand the diameter, and the fitted O-ring is compressed to maintain the airtightness of the container. The fastening member 4 is made of, for example, stainless steel or a metal that has been treated to be rust-proof.

[0013] The cartridge 6 has a cylindrical filter body 6a containing a filter medium, and is detachably fixed to a cartridge attachment portion (not shown) in the container lid 3. The raw water inlet pipe 3a of the container lid 3 communicates with the space inside the container body 2 and outside the filter body 6a, and the purified water outlet pipe 3b communicates with the inside of the filter body 6a. The material of the filter body 6a is, for example, resin, and the filter material is composed of a hollow fiber membrane, activated carbon, an ion exchanger, or the like.

[0014] As shown in FIG. 2, the upper attachment 10 includes an upper holding member 11 that detachably holds the container lid 3, and an upper fixing member 16 that fixes the upper holding member 11 to the wall surface 7. In this embodiment, the upper holding member 11 and the upper fixing member 16 are plate-shaped with a uniform thickness. A shaft core 15 is provided at the joint between the upper holding member 11 and the upper fixing member 16, and the upper holding member 11, the upper fixing member 16 and the shaft core 15 form a hinge structure. This allows the upper holding member 11 to rotate relative to the upper fixing member 16. Specifically, an axle tube 14 is formed by bending one end of the upper holding member 11, and an axle tube 19 is also formed by bending one end of the upper fixing member 16. The axle tube 14 of the upper holding member 11 and the axle tube 19 of the upper fixing member 16 are combined so as to be coaxial, and the axle core 15, which serves as the axis of rotation, is inserted into the axle tube 14 and the axle tube 19 to form a hinge structure.

[0015] Two through holes 12, 12 are provided in the upper holding member 11. The through holes 12, 12 are aligned in a row along a direction perpendicular to the axial direction of rotation (the length direction of the shaft core 15). The through holes 12, 12 are provided in positions coaxial with the raw water inlet pipe 3a and the purified water outlet pipe 3b of the container lid 3. The inner diameter of the through hole 12 is formed slightly larger than the outer diameters of the raw water inlet pipe 3a and the purified water outlet pipe 3b. As shown in Figure 1, the raw water inlet pipe 3a and the purified water outlet pipe 3b of the container lid 3 are inserted into the through hole 12, and the upper holding member 11 is sandwiched between the fixing nut 13 and the container lid 3 and tightened, so that the container lid 3 can be fixed to the upper holding member 11. In addition, the through holes 12, 12 provided in the upper holding member 11 may be aligned in a row along a direction parallel to the axial direction of rotation (the length direction of the axis 15) in accordance with changes in the positions of the raw water inlet pipe 3a and the purified water outlet pipe 3b of the container lid 3.

[0016] The upper fixing member 16 is provided with a number of screw holes. Reference numeral 17 denotes a round screw hole, and reference numeral 18 denotes an elongated hole having an enlarged diameter portion at the bottom. The upper fixing member 16 can be fixed to a wall surface by inserting a fixing screw 10a through one or more of these screw holes and screwing it to the wall surface. The upper holding member 11 is made of, for example, stainless steel or a metal that has been treated to be rust-proof. The upper fixing member 16 is made of, for example, stainless steel or a metal that has been treated to be rust-proof.

[0017] 3, the lower attachment 20 has a lower support member 21 on which the bottom of the container body 2 is placed, and a lower fixing member 26 that fixes the lower support member 21 to the wall surface 7. The lower support member 21 and the lower fixing member 26 are integrated together. The lower fixing member 26 is provided with a screw hole 27. The screw hole 27 is an elongated hole having an enlarged diameter portion in the vertical center. As shown in Fig. 1, the lower fixing member 26 can be fixed to a wall surface by inserting a fixing screw 20a through the screw hole 27 and screwing it to the wall surface.

[0018] In this embodiment, the lower support member 21 and the lower fixing member 26 are plate-shaped with a uniform thickness, and the angle they form is 90°. The lower attachment 20 has an L-shape obtained by bending a plate-shaped member at a linear bending portion 25. Two through holes 22, 22 are provided in the lower support member 21. The through holes 22, 22 are aligned in a row along a direction perpendicular to the straight line direction of the bent portion 25. The size and spacing of the through holes 22, 22 are the same as those of the through holes 12, 12 of the upper mounting fixture 10. The material of the lower mounting fixture 20 is, for example, stainless steel or a metal that has been treated to be rust-proof.

[0019] 4, the body attachment tool 30 has an arm part 31 that detachably holds the body part of the container body 2, and a body fixing member 36 that fixes the arm part 31 to the wall surface 7. The body fixing member 36 is a plate-like member with a uniform thickness, and has a plurality of screw holes 37. The arm portion 31 has a generally semicircular shape with a portion of the ring cut out, and is configured to bend in the direction of expanding its diameter. The inner diameter of the arm portion 31 is slightly smaller than the outer diameter of the container body 2, so that the arm portion 31 can embrace and closely contact the outer circumferential surface of the container body 2. The distance L between the end faces 31a, 31b of the arm portion 31 is configured such that the container body 2 cannot pass through when the arm portion 31 is not bent, but can pass through when the arm portion 31 is bent in the radially expanding direction. When arm portion 31 is viewed in a plan view from above, the straight line connecting end faces 31a, 31b is parallel to body fixing member 36. In other words, when arm portion 31 is holding container body 2 and container body 2 moves in a direction away from body fixing member 36, container body 2 comes off arm portion 31.

[0020] The arm portion 31 is fixed to a body fixing member 36 via a beam portion 33 . The beam portion 33 has a plate-like flange portion 33a and a web portion 33b that rise vertically from the body fixing member 36. It is preferable that the arm portion 31, the beam portion 33 and the body fixing member 36 are integrally formed. The material of the body attachment device 30 is, for example, resin, stainless steel, or metal that has been treated to be rust-proof.

[0021] The method of mounting the water purifier 1 to a wall surface 7 using the mounting kit of this embodiment is to first fix the upper fixing member 16, the lower fixing member 26, and the body fixing member 36 to the wall surface 7, as shown in Fig. 1. In this embodiment, the axis P of the container body 2 is vertical. The raw water inlet pipe 3a and the purified water outlet pipe 3b of the container lid 3 are inserted into the through hole 12 of the upper holding member 11, the bottom surface of the container body 2 is placed on the lower support member 21, and the arm portion 31 of the body mounting fixture 30 is bent to expand its diameter while fitting the body of the container body 2. Fixing nuts 13 are screwed onto the raw water inlet pipe 3a and the purified water outlet pipe 3b, respectively, and tightened to fix the container lid 3 to the upper holding member 11. Hoses 41a, 41b are attached to the raw water inlet pipe 3a and the purified water outlet pipe 3b, respectively. With the container lid 3 fixed to the upper holding member 11, it is preferable that the upper holding member 11 is approximately perpendicular to the axis P of the container body. It is preferable to measure the dimensions of the water purifier 1 in the direction of the axis P in advance and determine the fixing positions of the upper mounting fixture 10 and the lower mounting fixture 20.

[0022] It is preferable that the fixing position of the body attachment device 30 in the direction of axis P be set so that the container body 2 can easily detach from the arm portion 31 when the container body 2 is swung in a direction away from the wall surface 7 (hereinafter also referred to as the "removal direction"), as described below. For example, it is preferable to determine the position of arm portion 31 in the direction of axis P so that the inclination of axis P when container body 2 has passed between end faces 31a, 31b of arm portion 31 is 9 to 20°.

[0023] In this way, a mounting structure for a pressure-resistant water purifier is obtained, in which the upper fixing member 16 is fixed to the wall surface 7, the upper holding member 11 holds the container lid 3, the lower fixing member 26 is fixed to the wall surface 7, the bottom of the container body 2 is placed on the lower support member 21, the body fixing member 36 is fixed to the wall surface 7, and the body of the container body 2 is held by the arm portion 31. The upper holding member 11 is rotatable about the shaft core 15 relative to the upper fixing member 16. That is, it is rotatable in a direction that changes the angle between the upper holding member 11 and the wall surface 7. Therefore, when the bottom part of the container body 2 is pulled out in a direction away from the wall surface 7 (removal direction), the container body 2 swings about the shaft core 15 and comes off the arm part 31.

[0024] <How to replace the water purification cartridge> A method for replacing the water purification cartridge 6 of the water purifier 1 using the water purifier mounting structure of this embodiment will be described with reference to Figures 5 to 7. In Figures 5 to 7, the same components as those in Figures 1 to 4 are given the same reference numerals and their description will be omitted. 5, the fastening member 4 is removed while the upper holding member 11 holds the container lid 3, the arm portion 31 holds the trunk of the container body 2, and the bottom of the container body 2 is placed on the lower support member 21. At this time, the lower support member 21 prevents the container body 2 from falling, so the fastening member 4 can be removed with both hands.

[0025] Next, as shown in FIG. 6, the container body 2 is swung to be removed from the lower support member 21 and from the arm portion 31. Next, as shown in FIG. 7, the container body 2 is slid downward to remove it from the container lid 3 to expose the water purification cartridge 6, and the water purification cartridge 6 is replaced with a new water purification cartridge.

[0026] After the replacement, the container body 2 is attached to the container lid 3, the bottom of the container body 2 is placed on the lower support member 21, and the trunk of the container body 2 is fitted into the arm portion 31. In this state, the container body 2 will not fall even if both hands are released. Therefore, the work of attaching and fastening the fastening member 4 can be performed using both hands.

[0027] According to this embodiment, the pressure-resistant water purifier 1 can be installed on a wall surface, and the water purification cartridge can be easily replaced while the container lid 3 with the hoses 41a, 41b attached thereto remains installed on the wall surface . In particular, the fastening member 4 can be removed and attached using both hands, and the cartridge replacement work can be performed by one person. In addition, after the fastening member 4 is removed, the container body 2 can be swung, so that the container body 2 can be slid downward avoiding the lower support member 21. Furthermore, by providing the body mounting fixture 30, the stability of the pressure-resistant water purifier 1 when it is installed on a wall surface is increased.

[0028] The mounting kit of this embodiment can be used in common with water purifiers 1 having different lengths in the axial P direction because the distance between the upper mounting fixture 10 and the lower mounting fixture 20 can be freely changed. The mounting kit of this embodiment may further include a gauge such as a template that serves as a guide for positioning the upper mounting fixture 10 and the lower mounting fixture 20. For example, the gauge can indicate the fixing positions of the upper mounting fixture 10 and the lower mounting fixture 20 according to the size of the water purifier measured in advance.

[0029] In this embodiment, the through hole 22 of the lower support member 21 is not essential, but the lower mounting fixture 20 having the through hole 22 has the advantage that it can also be used as an upper mounting fixture when the water purifier 1 is placed on the floor.

[0030] It should be noted that the present invention is not limited to the above-described embodiment, and additions, omissions, substitutions, and other modifications of the configuration are possible without departing from the spirit of the present invention. For example, the mounting kit in the above embodiment includes the upper mounting fixture 10, the lower mounting fixture 20, and the body mounting fixture 30, but it is sufficient that the mounting kit includes at least the upper mounting fixture 10 and the lower mounting fixture 20.

[0031] In the above embodiment, the upper mounting fixture 10 is a member in which the upper holding member 11 and the upper fixing member 16 are integrated, but the upper holding member 11 and the upper fixing member 16 may be separate. For example, the upper holding member 11 and the upper fixing member 16, which do not have a hinge structure, may be attached to both wings of a hinge to form the upper mounting fixture 10. Alternatively, the upper holding member 11, which does not have a hinge structure, may be attached to one wing of a hinge to form the upper mounting fixture 10, and the other wing may be fixed to the wall surface as the upper fixing member.

[0032] In the above embodiment, the lower support member 21 is plate-shaped, but the lower support member 21 may have any shape as long as it can prevent the container body 2 from falling and allows the container body 2 to swing in the removal direction, and may be modified as appropriate.

[0033] In the above embodiment, the axis P of the container body 2 is in the vertical direction, but is not limited to this. If the axis P is inclined with respect to the vertical direction, the orientation and shape of the lower support member 21 may be appropriately changed so that the lower support member 21 can prevent the container body 2 from falling.
