Ion exchange treatment unit

Abstract

To provide an ion exchange treatment device that can prevent tipping during use. [Solution] The pure water purifier (ion exchange treatment unit) 10 comprises a main body 11 having an internal space 16 capable of accommodating ion exchange resin, an inlet 19 that allows water to flow into the internal space 16 and an inlet-side connection part 12 to which a faucet-side hose H1 can be connected, an outlet 20 that communicates with the internal space 16 and is located at the top and to which a nozzle-side hose H2 can be connected, and a hose locking part 15 located below the hose locking part 13 that is capable of supporting the nozzle-side hose H2 connected to the hose locking part 13. Therefore, when in use, the nozzle-side hose H2 extending from the hose locking part 15 can be supported. As a result, when the nozzle-side hose H2 is pulled during use, the force is applied below the hose locking part 13 of the pure water purifier 10, so unlike when the force is applied at the height of the hose locking part 13, it is possible to prevent it from tipping over.

Description

[Technical Field]

[0001] The present disclosure relates to an ion exchange processor. [Background Art]

[0002] Conventionally, washing vehicles with tap water (hereinafter referred to as "car washing") has been widely and generally performed. When a car is washed with tap water, impurities such as minerals contained in tap water may adhere to the vehicle body, and ion deposits (water scale) may form on the surface of the vehicle body after the vehicle dries. In order to prevent the formation of ion deposits, it is necessary to completely wipe off water after washing, which requires extra labor for car washing. For this reason, it has been practiced to prevent the formation of water scale by removing impurities such as minerals from tap water using an ion exchange processor such as a deionizer, and then washing the car with pure water from which such impurities have been removed.

[0003] For example, Patent Document 1 discloses an ion exchange processor used as a deionizer. This deionizer includes a main body portion that produces pure water, and a pedestal portion that supports the main body portion, and is configured in an upright shape such that the main body portion extends upward from the pedestal portion. The deionizer is provided with, for example, an inflow port provided on the pedestal portion, connected to a hose on the tap faucet side to allow water inflow, and an outflow port provided at an upper position of the main body portion, connected to a hose on the water spray nozzle side to allow water outflow. The deionizer has a function of removing impurities such as minerals from water (tap water) flowing in from the inflow port to produce pure water, and causing the produced water (pure water) to flow out from the outflow port.

[0004] [Patent Document 1] Registered Utility Model Publication No. 3246176 [Summary of the Invention] [Problem to be Solved by the Invention]

[0005] In ion exchange treatment devices that have an outlet at the top of the main body, such as the pure water device described in Patent Document 1, there is a possibility that the ion exchange treatment device may tip over when the hose on the watering nozzle side connected to the outlet is pulled during use.

[0006] Therefore, this disclosure aims to provide an ion exchange processor that can suppress tipping during use. [Means for solving the problem]

[0007] To solve the above problems, the ion exchange processor according to the first aspect of the present invention comprises: a main body having an internal space capable of accommodating an ion exchange resin; an inlet having an inlet that allows water to flow into the internal space and to which an upstream water member can be connected; an outlet having an outlet communicating with the internal space and positioned at the top, to which a downstream water member can be connected; and a member support portion positioned below the outlet connection portion and capable of supporting the downstream member connected to the outlet connection portion.

[0008] A second aspect of the present invention is an ion exchange processor according to the first aspect, comprising a base portion positioned at the lower end and supporting the main body portion so that it can stand upright, wherein the member support portion is integrally provided with the base portion.

[0009] A third aspect of the present invention is an ion exchange processor according to the first or second aspect, wherein the member support portion is arranged in the same direction as the outlet side connection portion in the circumferential direction of the main body portion when viewed from above.

[0010] A fourth aspect of the present invention is an ion exchange processor according to the second aspect, wherein the base portion has at least two protrusions arranged on both sides of the member support portion in the circumferential direction in the circumferential direction of the main body portion when viewed from above, and protruding in a direction away from the main body portion. [Effects of the Invention]

[0011] According to this disclosure, it is possible to provide an ion exchange processor that can suppress tipping during use. [Brief explanation of the drawing]

[0014] Figure 1 is a perspective view of an ion exchange processor according to one embodiment of the present invention. Figure 2 is a cross-sectional view taken along the line II-II in Figure 1. Figure 3 is a perspective view of the base. Figure 4 is a plan view of the base. Figure 5 is a side view of the base.

[0015] As shown in Figure 1, an ion exchange treatment device according to one embodiment of the present invention is a water purifier (ion exchange treatment device) 10 for producing pure water by removing impurities such as minerals from tap water, and is used, for example, to suppress the generation of limescale when washing a car. As shown in Figure 2, when washing a car, the water purifier 10 is used by connecting a tap-side hose (upstream member) H1 provided on the tap side of the water supply and a nozzle-side hose (downstream member) H2 with a nozzle (not shown) such as a shower head at its tip. The water purifier 10 produces pure water by removing impurities such as minerals from the water (tap water) flowing in from the tap-side hose H1, and discharges the produced water (pure water) from the nozzle-side hose H2.

[0016] As shown in Figures 1 and 2, the pure water purifier 10 according to this embodiment comprises a main body 11 that generates pure water, an inlet-side connection part 12 to which a faucet-side hose H1 can be connected, an outlet-side connection part 13 to which a nozzle-side hose H2 can be connected, and a hose locking part (member support part) 15. Furthermore, in addition to these, the pure water purifier 10 of this embodiment also comprises a base part 14 that supports the main body 11 so that it can stand upright. Note that if the main body 11 can stand upright on its own, the base part 14 may not be necessary.

[0017] As shown in Figure 2, the main body 11 has an internal space 16 capable of accommodating ion exchange resin. The main body 11 of this embodiment is formed in a shape that extends vertically and partitions the internal space 16 on its inside. The main body 11 of this embodiment has a container portion 17 that is formed in a bottomed cylindrical shape that opens upward and partitions the lower and side of the internal space 16, and a lid portion 18 that closes the upper opening of the container portion 17 and partitions the upper part of the internal space 16. The lid portion 18 is detachably attached to the container portion 17. The main body 11 of this embodiment is used in a vertical position with its lower end supported by a base portion 14, which will be described later.

[0018] In this embodiment, an outlet-side connection part 13 is provided at the top of the water purifier 10 (the lid part 18 of the main body part 11), and an inlet-side connection part 12 is provided at the bottom of the water purifier 10 (the bottom of the main body part 11). The inlet-side connection part 12 has an inlet 19 that communicates with the internal space 16 and allows water to flow into the internal space 16. The outlet-side connection part 13 has an outlet 20 that communicates with the internal space 16 and allows water to flow out from the internal space 16. In this embodiment, the inlet-side connection part 12 is provided at the bottom of the water purifier 10, but this is not the only option, and for example, the inlet-side connection part 12 may be provided at the top of the water purifier 10.

[0019] In the present embodiment, the inflow-side connection portion 12 and the outflow-side connection portion 13 are arranged in a straight line in the front-rear direction in a top view, and extend in a direction away from each other from the main body portion 11 side. In the present embodiment, although the inflow-side connection portion 12 and the outflow-side connection portion 13 are arranged on a straight line, the present invention is not limited to this arrangement. Furthermore, in the present embodiment, the inflow-side connection portion 12 and the outflow-side connection portion 13 extend in a direction away from each other from the main body portion 11 side, but the present invention is not limited thereto; for example, the inflow-side connection portion 12 and the outflow-side connection portion 13 may extend in the vertical direction.

[0020] The internal space 16 of the main body portion 11 communicates with the inflow port 19 via a flow path 21 at the lower end portion of the main body portion 11. In the present embodiment, the flow path 21 extending from the inflow port 19 communicates with the lower end portion of the internal space 16. Furthermore, the internal space 16 of the main body portion 11 communicates with the outflow port 20 via a flow path 22 in the lid portion 18. The flow path 22 in the lid portion 18 extends from the upper end of the internal space 16 in a direction intersecting the vertical direction, and communicates with the outflow port 20 of the outflow-side connection portion 13. The main body portion 11 allows water to flow into the internal space 16 from the inflow port 19, and allows water to flow out from the internal space 16 to the outflow port 20 side.

[0021] An ion exchange resin bag B filled with an ion exchange resin (not shown) is accommodated in the internal space 16. The ion exchange resin has the property of removing calcium (calcium ions), magnesium (magnesium ions), chloride (chloride ions) and the like dissolved in water. The ion exchange resin is, for example, a mixed resin of a cation exchange resin that exchanges cations (positive ions) and an anion exchange resin that exchanges anions (negative ions). The cation exchange resin takes in cations and releases hydrogen ions, and the anion exchange resin takes in anions and releases hydroxide ions. The released hydrogen ions and hydroxide ions combine to form water. In FIG. 2, the interior of the water purifier 10 is illustrated with solid lines.

[0022] As shown in Figures 1 and 2, the lid portion 18 of this embodiment has an on-off valve (not shown) in the flow path 22 upstream of the outlet side connection portion 13. The on-off valve can be switched between an open state and a closed state by operating an externally provided operating lever 23.

[0023] As shown in Figures 3 to 5, the base portion 14 supports the main body portion 11 so that it can stand upright. In this embodiment, the base portion 14 is positioned at the lower end of the pure water purifier 10 and supports the lower end of the main body portion 11.

[0024] As shown in Figures 3 to 5, the base portion 14 of this embodiment has a base portion 24 that supports the lower end of the main body portion 11, four protrusions 25a to 25d that project radially outward from the base portion 24, and a hose locking portion (member support portion) 15 integrally provided in front of the base portion 24. The lower surface of the base portion 14 (the lower surface of the base portion 24 and the four protrusions 25a to 25d) is formed to be substantially flat and constitutes the lower surface of the pure water purifier 10.

[0025] The base portion 24 of the pedestal portion 14 is the central portion that supports the main body portion 11, and has a circular through hole 26 that penetrates vertically, and an annular support plate 28 that protrudes radially inward from the inner circumferential surface 27 of the through hole 26. The through hole 26 has a diameter larger than the lower end of the main body portion 11 and is formed to a size that allows the lower end of the main body portion 11 to be inserted from above. The inner circumferential surface 27 of the through hole 26 is formed to be close to or in contact with the outer circumferential surface of the lower end of the main body portion 11. The annular support plate 28 is a plate-like portion that supports the lower end of the main body portion 11 from below, and has a plurality (three in this embodiment) of bolt insertion holes 29. The bolt insertion holes 29 are arranged at equal intervals in the circumferential direction of the annular support plate 28. Female threads (not shown) are formed on the lower surface of the main body portion 11 at positions corresponding to the bolt insertion holes 29. The base portion 24 has a notch 30 formed by cutting out a portion of the inner circumferential surface 27 of the through hole 26 above the annular support plate 28 in the circumferential direction (circumferential direction centered on point O in Figure 4) from above. The notch 30 is positioned corresponding to the rear of the base portion 24 and is formed to avoid interference between the inflow-side connection portion 12, which protrudes rearward from the lower end of the main body portion 11, and the base portion 24.

[0026] When fixing the main body 11 and the base 14, first, the lower end of the main body 11 is inserted from above into the through hole 26 of the base portion 24 of the base 14, and the lower surface of the main body 11 is brought into contact with the annular support plate 28 from above. At this time, the circumferential position is adjusted so that the inlet-side connection portion 12 of the lower end of the main body 11 is positioned within the notch 30. Then, fastening members such as bolts (not shown) are inserted from below into the bolt insertion holes 29 of the annular support plate 28 and fixed to the female threads (not shown) on the lower surface of the main body 11. Note that the shape and fixing method of the base 24 are not limited to the above, and any shape that can be fixed to the main body 11 is acceptable.

[0027] The four protrusions 25a to 25d of the base portion 14 are parts that protrude in all directions from the base portion 24 when viewed from above, and are formed integrally with the base portion 24. The four protrusions 25a to 25d consist of front left and right protrusions 25a and 25b, and rear left and right protrusions 25c and 25d. The front left and right protrusions 25a and 25b protrude forward and to both sides from the base portion 24 and are provided symmetrically with respect to a center line extending in the front-rear direction passing through the center O of the base portion 24. The rear left and right protrusions 25c and 25d protrude backward and to both sides from the base portion 24 and are provided symmetrically with respect to a center line extending in the front-rear direction passing through the center O of the base portion 24. The upper surfaces of the four protrusions 25a to 25d are inclined surfaces that become lower as they move away from the base portion 24. Note that the shape of the protrusions 25a to 25d is not limited to the above. Furthermore, the shape of the base portion 14 is not limited to a shape having protrusions 25a to 25d.

[0028] As shown in Figure 2, the hose locking portion 15 is a part capable of supporting (locking, in this embodiment) the nozzle-side hose H2, and is positioned below the outlet-side connection portion 13. In this embodiment, the hose locking portion 15 is integrally provided with the base portion 24. Furthermore, in the circumferential direction of the main body portion 11 in a top view (circumferential direction centered on point O in Figure 4), the hose locking portion 15 is positioned in the same direction (forward) as the outlet-side connection portion 13.

[0029] As shown in Figures 3 to 5, the hose locking portion 15 of this embodiment is provided in the area between the left and right protrusions 25a and 25b on the front side of the base portion 14. That is, the base portion 14 of this embodiment has at least two protrusions 25a and 25b that are arranged on both sides of the circumferential direction of the hose locking portion 15 in the circumferential direction of the main body portion 11 in a top view, and protrude in a direction away from the main body portion 11. In a top view, the hose locking portion 15 is located in front of the through hole 26 of the base portion 14. As a result, as shown in Figure 2, it is located in front of the main body portion 11, and a wide space 32 extends above the hose locking portion 15 (above the hose insertion space 31). The hose locking portion 15 of this embodiment has left and right arm portions 15a that protrude forward and upward from the area between the left and right protrusions 25a and 25b on the front side of the base portion 14, and a connecting portion 15b that connects the tips of the left and right arm portions 15a, and defines a hose insertion space 31 inside. Because the left and right arm portions 15a protrude forward and upward from the base portion 14, and the connecting portion 15b connects the tips of the left and right arm portions 15a, the hose locking portion 15 is located above the height of the lower surface of the pure water purifier 10. As a result, a space 33 is provided between the hose locking portion 15 and the mounting surface A on which the pure water purifier 10 is placed, below the hose locking portion 15 (below the hose insertion space 31). The hose locking portion 15 is formed to a size that allows the nozzle-side hose H2 to be inserted into the hose insertion space 31. In this embodiment, the hose locking portion 15 is formed to a size that allows the insertion of the connection portion H2a of the nozzle-side hose H2 to the outlet-side connection portion 13. The hose locking portion 15 can support the nozzle-side hose H2 by inserting the nozzle-side hose H2 into the hose insertion space 31.

[0030] The shape of the hose locking portion 15 is not limited to the above, and any shape that can support the nozzle-side hose H2 is acceptable. Also, in this embodiment, the hose locking portion 15 is provided in the same direction as the outlet-side connection portion 13 when viewed from above, but this is not the only way to do so. Also, in this embodiment, the hose locking portion 15 is provided integrally with the base portion 14, but this is not the only way to do so; it is acceptable as long as it is located below the outlet-side connection portion 13 in the pure water purifier 10. For example, the hose locking portion 15 may be formed separately from the base portion 14, or the hose locking portion 15 may be formed to be detachable from the main body portion 11 or the base portion 14. In this case, the circumferential position of the hose locking portion 15 may be adjustable to any position.

[0031] When using the water purifier 10, connect the faucet-side hose H1 to the inlet-side connection 12 and the nozzle-side hose H2 to the outlet-side connection 13. At this time, insert the connection part H2a of the nozzle-side hose H2 from the space 33 below the hose locking part 15 into the hose insertion space 31 and connect it to the outlet-side connection 13 above. Next, open the faucet (not shown) and allow water (tap water) to flow into the internal space 16 of the main body 11 for use. At this time, the connection part H2a of the nozzle-side hose H2 may be directly connected to the outlet-side connection 13, but it may also be connected indirectly via peripheral equipment such as a flow meter or a TDS (Total Dissolved Solids) meter without directly connecting the nozzle-side hose H2. A TDS meter is a measuring instrument capable of measuring the total amount of inorganic substances dissolved in water. A TDS meter measures the conductivity of the electric current flowing through water by utilizing the property that water containing many inorganic ions conducts electricity easily, while pure water, which does not contain inorganic ions, does not conduct electricity. This conductivity is expressed in ppm, the unit of concentration for electrolytic substances (inorganic salts). Since pure water is almost an insulator, the value measured by a TDS meter will be close to zero. On the other hand, if the water contains many dissolved ions, the value measured by a TDS meter will be high.

[0032] In the pure water purifier 10 configured as described above, a hose locking part 15 is located below the outlet connection part 13 and is capable of supporting the nozzle-side hose H2 connected to the outlet connection part 13. Therefore, when in use, the nozzle-side hose H2 extending from the outlet connection part 13 can be supported by the hose locking part 15. As a result, when the nozzle-side hose H2 is pulled during use, the force is applied below the outlet connection part 13 of the pure water purifier 10, which is different from when the force is applied at the height of the outlet connection part 13, thus preventing it from tipping over.

[0033] Therefore, according to this embodiment, it is possible to provide an ion exchange treatment device (pure water treatment device 10) that can suppress tipping over during use.

[0034] Furthermore, by integrally providing the hose locking portion 15 with the base portion 14, when the nozzle-side hose H2 is pulled during use, that force can be applied to the lower end of the pure water purifier 10. This makes the pure water purifier 10 even less likely to tip over during use.

[0035] Furthermore, by positioning the hose locking portion 15 in the same direction as the outlet side connection portion 13 when viewed from above, the nozzle side hose H2 can be supported in a balanced manner.

[0036] Furthermore, by providing at least two protrusions 25a and 25b on both sides in the circumferential direction of the hose locking portion 15 of the base portion 14, the pure water purifier 10 becomes even less likely to tip forward.

[0037] The present invention has been described above based on the above embodiments. However, the present invention is not limited to the contents of the above embodiments, and can naturally be modified as appropriate without departing from the present invention. In other words, all other embodiments, examples, and operational techniques made by those skilled in the art based on these embodiments are, of course, included in the scope of the present invention.
