Description

[Technical field]

[0001] The present invention relates to a TDS water quality tester and a testing unit including the TDS water quality tester. [Background technology]

[0002] Water quality testing is conducted on water supplied from a water supply system to ensure that it meets a specified standard. For example, a water purifier, which is an example of a water supply system, is a device that converts ordinary water into water close to pure water by ion exchange reaction or the like. It is important to know the level of water quality of such water supply systems such as water purifiers in order to maintain the quality of the water supplied.

[0003] Conventionally, TDS (Total Dissolved Solids) has been known as an index for evaluating the quality of water supplied from a water purifier. TDS indicates the total amount of inorganic matter, such as salts and metals, and organic matter, such as organic compounds, dissolved in water. TDS water quality testers generally measure the electrical conductivity of the water being tested, use the electrical conductivity to obtain the TDS value through a specified internal formula, and display the value on an LCD display or similar device.

[0004] When testing the quality of water supplied from a water supply device using a TDS water quality tester, one method is to place the probe (sensor part) of a stick-shaped TDS water quality tester in purified water, as exemplified in Patent Document 1. Another method is known in which a T-shaped pipe fitting called a "tee" is inserted into the existing hose or pipe from the water purifier, and a TDS water quality tester is attached to it. This method has the advantage that the TDS value can be displayed whenever you want to check the quality of the water, allowing you to test the quality of the water.

[0005] [Patent Document 1] Utility Model Registration No. 3249308 Summary of the Invention [Problem to be solved by the invention]

[0006] However, the method of immersing the sensor part of a stick-shaped TDS water quality tester in the water from the water purifier requires removing the top cover of the water purifier to conduct the test, which is time-consuming and makes the testing process complicated. The method of installing a TDS water quality tester by inserting a T-shaped piping part often involves complicated installation procedures, making the installation operation difficult. In addition, when installing a T-shaped piping part, it is often installed on the main body of the water purifier, making it difficult to install it on the nozzle hose.

[0007] The purpose of this invention is to provide a TDS water quality tester and a TDS water quality testing unit that can be easily attached and detached with a single touch, and that can be attached not only to the main body of a water supply device, but also to the tip of a pipe such as a hose if necessary.

[0017] [First embodiment] Hereinafter, a TDS water quality tester 1 according to a first embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a diagram for explaining the first embodiment. In the explanation of the TDS water quality tester 1 in Fig. 1, the inlet 3 side in the direction of water flow in the TDS water quality tester 1 is referred to as the upstream side (base end side), and the outlet 4 side is referred to as the downstream side (tip side). The TDS water quality tester 1 has two openings, the inlet 3 and the outlet 4, but since the TDS water quality tester 1 may be connected to the water supply device 14 in such a way that the TDS water quality tester 1 is reversed as shown in Figs. 3 and 4, the inlet 3 and the outlet 4 are not fixed, and the opening on the upstream side is always the inlet 3, and the opening on the downstream side is always the outlet 4.

[0018] The up-down direction of the TDS water quality tester 1 shown in Figure 1 is shown for convenience as the direction along the surface including the information display unit 10 when three axes are taken perpendicular to the water flow direction, and can be changed appropriately depending on how the TDS water quality tester 1 is attached to a specified pipeline such as a water supply device 14 or a hose.

[0019] The TDS water quality tester 1 according to this embodiment includes a water quality test main body 2. The water quality test main body 2 includes a TDS water quality test component (not shown). The water quality test main body 2 may have various external shapes such as a rectangular parallelepiped, cylindrical, or trapezoidal solid shape. The water quality test main body 2 itself includes an inlet 3 and an outlet 4. The inlet 3 includes an inlet side connector 5, and the outlet 4 includes an outlet side connector 6. The configurations of the inlet side connector 5 and the outlet side connector 6 are determined by the configuration of the outlet of the water supply device 14 to be used and the number of types of predetermined pipes to be used. If the water supply device 14 to be used has many types of outlets and many types of connection configurations and pipe diameters, an adapter section to be described later that corresponds to each of those connection configurations is required.

[0020] In the configuration shown in Fig. 1, the type of inlet connector 5 and the type of outlet connector 6 are different. That is, one of the inlet connector 5 and the outlet connector 6 is composed of a pipe insertion connector 7 such as a nipple 12, and the other is composed of an externally threaded pipe 9 having a male thread 8 formed around the periphery of the pipe. If necessary, the externally threaded pipe 9 can be replaced with an internally threaded pipe (not shown) having a female thread (not shown) formed on the periphery. The selection of this connector is determined taking into consideration the expected mode of use, as described above.

[0021] As another example of a configuration in which the type of the inlet connector 5 and the type of the outlet connector 6 are different, one of the inlet connector 5 and the outlet connector 6 can be configured with an externally threaded tube 9 and the other with an internally threaded tube (not shown). In this configuration, the nipple 12 is not used.

[0022] There are also cases where the inlet side connector 5 and the outlet side connector 6 are configured with the same type of connector. For example, there are cases where both the inlet side connector 5 and the outlet side connector 6 are configured with an externally threaded pipe 9 or an internally threaded pipe, respectively. In many cases where the water supply device 14 has a base end pipe 25 (see FIG. 4) configured with a hose and a tip end pipe 24 (see FIG. 4) configured with a hose, both the inlet side connector 5 and the outlet side connector 6 of the TDS water quality tester 1 can be configured with nipples 12.

[0023] As shown in Fig. 1, the water quality test main body 2 has an information display unit 10 that displays information related to water quality evaluation, and a light-emitting unit 11 that displays the battery capacity of the TDS water quality tester 1 by color. A low-power liquid crystal display device or the like is used for the information display unit 10, and the TDS value or the like is usually displayed. An example of the light-emitting unit 11 is an LED light-emitting element, which, when the battery capacity becomes lower than a specified level, emits light in a specified color such as red to inform the user that the battery capacity is low.

[0024] If necessary, it is also possible to provide a warning unit (for example, a light-emitting unit (not shown)) that displays a warning when the TDS value falls below a predetermined water quality. Although not shown in FIG. 1, a start switch for starting the operation of the TDS water quality tester 1 is provided on the water quality test main body 2 or the like.

[0025] FIG. 2 is a perspective view showing a water purifier 15 as an example of a water supply device 14 to which the TDS water quality tester 1 is attached. As shown in FIG. 2, the water purifier 15 is a device for producing purified water (pure water) by removing impurities such as minerals from tap water, and is used, for example, to suppress the formation of limescale when washing a car.

[0026] This water purifier 15 has a handle 16 and is a compact, portable water purifier 15. The water purifier 15 has a water purification main body 17 that produces pure water, a base 18 that supports the water purification main body 17, and a lid 19, and is configured in an upright shape so that the water purification main body 17 extends upward from the base 18.

[0027] The water purifier 15 is provided with, for example, an inlet 20 provided on the base 18 and connected to a hose (not shown) on the water faucet side to allow water to flow in, and an outlet 21 provided at a position above the water purification main body 17 and connected to a hose (not shown) on the water spray nozzle (not shown) side to allow water to flow out. The water purifier 15 has a function of removing impurities such as minerals from the water (tap water) flowing in from the inlet 20 to generate pure water, and causing the generated water (pure water) to flow out from the outlet 21. This flow is indicated by an arrow of an upward flow 22 in which water flows from the bottom to the top of the water purifier 15.

[0028] However, a configuration in which the inlet 20 is provided at an upper position of the water purifier 15 and the outlet 21 is provided at a lower position of the water purifier 15 can also be adopted. In this case, water flows from the top to the bottom of the water purifier 15, and this flow is indicated by the downward flow arrow 23.

[0029] The TDS water quality tester 1 according to the present invention can be connected to the outlet 21 provided at the lower or upper position. In addition, as described below, the TDS water quality tester 1 can also be connected to a predetermined pipe such as a hose connected to the outlet 21.

[0030] The water purifier 15 is often configured to purify water by ion exchange. Ion exchange resins that realize ion exchange have the property of removing calcium (calcium ion), magnesium (magnesium ion), chloride (chloride ion), etc. dissolved in water. Ion exchange resins are often composed of a mixed resin of a cation exchange resin that exchanges cations (positive ions) and an anion exchange resin that exchanges anions (negative ions). Cation exchange resins take in cations and release hydrogen ions, while anion exchange resins take in anions and release hydroxide ions. The released hydrogen ions and hydroxide ions combine to become water.

[0031] In the water purifier 15 that can be used in the present invention, a cartridge type configuration can be appropriately adopted in which a cartridge containing ion exchange resin is stored in accordance with the internal space of the water purification main body 17. The ion exchange process in the cartridge can be performed in a form other than the ion exchange described above, depending on the type of ion exchange resin used to treat the water. As described above, the water purifier 15 in this invention is illustrated as an example of the water supply device 14 to which the TDS water quality tester 1 is attached, and the water supply device 14 is not limited to the water purifier 15.

[0032] FIG. 3 is a schematic diagram for explaining a configuration in which a TDS water quality tester 1 is attached to the outlet 21 of a water purifier 15 (water supply device 14), a tip-side pipe 24 such as a hose is connected from the TDS water quality tester 1, and various nozzles 26 are provided at the tip of the tip-side pipe 24. In Fig. 3, an outlet side connector 27 of the outlet 21 is connected to an inlet side connector 5 represented by the externally threaded pipe 9 shown in Fig. 1, and an outlet side connector 6 such as the nipple 12 shown in Fig. 1 is connected to the base end side of the tip side conduit 24, with a nozzle 26 provided on the tip side of the tip side conduit 24. The nozzle 26 can be in the form of a straight nozzle, a wide-angle nozzle, a shower nozzle, a spray nozzle, or any other configuration suitable for various applications.

[0033] If the outlet side connector 27 provided on the water supply device 14 is composed of an internally threaded pipe (a pipe section having a female thread around it), it can be directly connected to the externally threaded pipe 9 (a pipe section having a male thread around it) of the TDS water quality tester 1.

[0034] Although not shown, in the configuration shown in Fig. 3, if the outlet side connector 27 of the water supply device 14 is composed of an externally threaded pipe 9 and the inlet side connector 5 of the TDS water quality tester 1 is also composed of an externally threaded pipe 9, an intermediate connector such as a socket is required to connect the two externally threaded pipes. The "intermediate" in "intermediate connector" means the intermediate between the outlet 21 of the water supply device 14 and the TDS water quality tester 1, or the intermediate of the water channel that is ultimately supplied, such as the intermediate between the base end pipe 25 (upstream pipe) and the tip end pipe 24 (downstream pipe) described later in Fig. 4.

[0035] 3, the water supply device 14 and the tip-side pipe 24 can be connected with only the TDS water quality tester 1 as a minimum unit, so the TDS water quality tester 1 can be easily and detachably attached to the outlet 21 of the water supply device 14 with a single touch. Therefore, a TDS water quality test configuration that can easily detect the state of water at all times can be realized. Furthermore, even in a configuration having an intermediate connector such as a socket, the TDS water quality tester 1 can be easily and detachably attached with a single touch, so that a TDS water quality test configuration can be easily realized.

[0036] FIG. 4 is a schematic diagram for explaining an example of a connection configuration of the TDS water quality tester 1 when a base end side pipeline 25 such as a hose is attached to the outlet 21. In this usage form, the base end side pipeline 25 is already attached to the outlet 21 of the water supply device 14, and the TDS water quality tester 1 is newly attached to the base end side pipeline 25.

[0037] In this case, the TDS water quality tester 1 itself shown in the configuration shown in Figure 3 is reversed between the upstream and downstream sides, and the nipple 12 of the TDS water quality tester 1 (in this case, the inlet side connector 5) is connected to the tip of the base end pipeline 25 connected to the outlet 21 of the water supply device 14, and the externally threaded pipe 9 of the TDS water quality tester 1 (in this case, the outlet side connector 6) is connected to the base end side of the tip end pipeline 24.

[0038] In this configuration, since the distal end side conduit 24 consisting of the externally threaded pipe 9 and the hose cannot be connected, a pipe-side connector 28, which is an intermediate connector 44, is provided. Such a pipe-side connector 28 is a connection part having, for example, an internally threaded pipe on the base end side and a nipple or the like on the distal end side that can be inserted into a hose. This pipe-side connector 28 also functions as an adapter part 46 that connects to each other, overcoming the difference in configurations that cannot be connected.

[0039] In addition to the configuration shown in FIG. 4, various combinations of configurations for disposing and connecting the TDS water quality tester 1 between the base end pipeline 25 and the tip end pipeline 24 can be used. For example, in order to specialize to the form shown in Fig. 4, it is possible to adopt a TDS water quality tester 1 in which both the inlet side connector 5 and the outlet side connector 6 are nipples. However, it can generally be said that it is easier to connect the TDS water quality tester 1 to various forms of water supply devices 14 if the TDS water quality tester 1 is combined with a threaded pipe having male or female thread engagement and an insertion connector for a hose such as a nipple. Although the outlet 21 of the water supply device 14 shown in Figures 3 to 6 is shown to be located away from the installation ground, an outlet 21 provided downward so as to be along the installation ground can also be used.

[0040] [Second embodiment] 5 and 6 are schematic diagrams for explaining a TDS water quality testing unit according to a second embodiment. As partially explained in Fig. 3 and Fig. 4, the first feature of the second embodiment is that the TDS water quality testing device 1 described in the first embodiment is used, an intermediate connector 44 is provided on at least one side of the inlet connector 5 and the outlet connector 6, and the intermediate connector 44 is configured to be connectable to the outlet 21 of the water supply device 14 or a predetermined pipeline related to the water supply of the water supply device 14. Examples of the predetermined pipeline include a base end pipeline 25 such as a hose and a tip end pipeline 24 such as a hose as shown in Fig. 6.

[0041] As shown in Figures 5 to 8, a second feature of the second embodiment is that the intermediate connector 44 can also be configured to include a rotary connection unit 30. The rotary connection unit 30 has a rotary adjustment part 31 equipped with a rotary part 32 that changes the water supply angle. In this specification, the term "rotation" is used as a concept that includes "rotation."

[0042] In the configuration shown in Fig. 5, an intermediate connector 44 is provided on the inlet connector 5 side of the TDS water quality tester 1. The intermediate connector 44 has a rotating connection unit 30. An externally threaded pipe 9 of the TDS water quality tester 1 is connected to the upstream side (outlet 21 side) of the rotating joint part 34 of the intermediate connector 44, and the nipple 12 of the TDS water quality tester 1 is connected to the tip side pipeline 24 on the downstream side. In the configuration shown in Fig. 5, the rotating part 32 is located at a position close to the outlet 21, so that it can be rotated to a position closer to the water supply device 14 side than the hose on the nozzle 26 side.

[0043] 6, an intermediate connector 44 is provided on the outlet connector 6 side of the TDS water quality tester 1. The intermediate connector 44 has a rotating connection unit 30. A base end pipe 25 is connected to the connection part of the outlet 21 of the water supply device 14, and a nipple 12 (an example of a pipe insertion connector) of the TDS water quality tester 1 is connected to the tip part of the base end pipe 25.

[0044] The configuration of the rotary connection unit 30 shown in Figures 5 and 6 will now be described. Fig. 7 is a perspective view showing an example of a TDS water quality testing unit including a pivot connection unit 30. Fig. 8 is an exploded view of the water quality testing unit shown in Fig. 7. As shown in FIG. 8, in this rotating connection unit 30, a basic connector part 33, a rotation adjustment part 31, a rotating joint part 34, and a TDS water quality tester 1 are connected in that order from the outlet 21 side (upstream side) to the downstream side.

[0045] The basic connector portion 33 has a first upstream connection portion 40 (e.g., an internally threaded pipe) and a second downstream connection portion 41 (e.g., an internally threaded pipe). In the configuration shown in Fig. 5, the outlet side connector 27 is constituted by an externally threaded pipe 9, so that the first connection portion 40 can be connected to the outlet side connector 27 by being an internally threaded pipe. In the configuration shown in Figure 5, the basic connector portion 33 functions as an adapter portion 46 that enables connection even when the outlet side connector 27 and the upstream connection portion of the rotation adjustment portion 31 cannot be engaged with each other.

[0046] In the configuration shown in Fig. 8, the rotation adjustment part 31 has a rotation part 32 in the middle part in the upstream and downstream flow direction, a third connection part 36 on the base end side, and a fourth connection part 37 on the tip end side. Fig. 8 shows a case where both the third connection part 36 and the fourth connection part 37 are externally threaded pipe fittings. The third connecting portion 36 engages with and is connected to the second connecting portion 41 of the basic connector portion 33 .

[0047] As shown in Fig. 7, the rotation axis 39 of the rotating part 32 is set in a direction intersecting the direction of water flow, preferably in a direction perpendicular to the direction. For example, the rotation axis 39 is arranged along the left-right direction in the coordinate system shown in Fig. 7, and the rotation angle θ is configured to be a large angle of up to 180° in the up-down direction. The rotation direction is arranged and set in the direction in which a pipe such as a hose moves significantly. In other words, when connecting to the outlet 21, the direction of the rotation axis 39 of the rotation connection unit 30 is set in the direction in which the hose or the like moves significantly.

[0048] 5 and 6, the angle between third connection part 36 (see FIG. 8) and fourth connection part 37 (see FIG. 8) can be changed by rotating part 32 within a range of rotation angle θ (see FIG. 7) depending on the movement of the hose, etc., thereby preventing the hose from bending or water supply device 14 from falling over. Furthermore, when a large force is applied to rotating part 32 in the pipeline, the rotating part 32 rotates in the direction of the force, so that it is possible to prevent large forces from being applied to each part of the TDS water quality testing unit, particularly to the connection parts which are easily damaged, compared to a configuration without rotating part 32.

[0049] As shown in Fig. 8, the rotating joint part 34 has a fifth connecting part 42 on the base end side and a sixth connecting part 43 on the tip end side. The fifth connecting part 42 is a connecting part that engages with the fourth connecting part 37 of the rotation adjustment part 31. The sixth connecting part 43 is a connecting part that can engage with the externally threaded pipe 9 (inlet side connector 5) of the TDS water quality tester 1. Fig. 8 shows a case where both the fifth connecting part 42 and the sixth connecting part 43 are internally threaded pipes.

[0050] The pivot joint portion 34 functions as an adapter portion 46 that connects even a connection portion where the fourth connection portion 37 and the externally threaded pipe 9 cannot engage with each other. If necessary, each of the first connection part 40 to the sixth connection part 43 can be changed depending on the type of outlet side connector 27 provided at the outlet 21 and the type of connectors provided at the inlet part 3 and outlet part 4 of the TDS water quality testing device 1.

[0051] By providing the rotation adjustment part 31 between the basic connector part 33 and the rotating joint part 34 and by appropriately changing the type of the basic connector part 33 and the rotating joint part 34, it is possible to advantageously interpose the rotating part 32 in various water supply devices 14. In addition, since the rotation axis position can be separated from the outlet 21, there are cases in which an unreasonable force is not applied and good rotation can be performed.

[0052] Next, in the configuration shown in FIG. 6, a description will be given of the connection configuration downstream of the TDS water quality tester 1. 6 shows a configuration in which a rotating joint part 34, a rotation adjustment part 31, and a basic connector part 33A are connected to an externally threaded pipe 9 of a TDS water quality tester 1. A tip-side pipe 24 such as a hose can be connected to the basic connector part 33A.

[0053] The basic connector part 33 shown in Fig. 5 and the basic connector part 33A shown in Fig. 6 have different connection configurations. The basic connector part 33A is a connection part that connects the downstream connection part of the rotation adjustment part 31 and the base end side of the hose. By providing the TDS water quality tester 1 with at least one adapter part 46 such as the basic connector parts 33 and 33A, a TDS water quality test unit that can be used in various ways can be configured.

[0054] [Other configurations] The present invention is not limited to the above-described embodiments, and modifications are possible within the scope of the present invention. For example, the rotating unit 32 may be configured as a universal joint type rotating unit 32 that allows the rotation axis 39 to be oriented in any direction relatively freely. However, the rotation range of the universal joint type rotating unit 32 generally tends to be smaller than that of the configuration shown in FIG.

[0055] It is clear that, since the intermediate connector 44 includes the adapter portion 46, the combination of the intermediate connector 44 and the TDS water quality testing unit including the TDS water quality tester 1 can provide a configuration that allows good connection regardless of, for example, the type of outlet side connector 27 or the type of specified pipeline.

[0056] In the above embodiment, the water supply device 14 has been described assuming that it is a water purifier 15 that supplies pure water used for washing a car. However, even if the water supply device (which can also be called a water supply source) is simply a faucet or a hose, the TDS water quality tester 1 or the TDS water quality test unit can be attached for the purpose of testing various types of water quality.

[0057] Although the present invention has been described above by way of examples, the technical scope of the present invention is not limited to the configurations described in the above embodiments. The technical scope of the present invention should be determined based on the description of the claims of the utility model registration, and it goes without saying that various modifications, additions to the configuration, or improvements can be made within that scope.
