Description

Technical Field

[0001] The present invention relates to a water faucet that adjusts a water discharge amount by steplessly operating a lever handle or the like, and more particularly to a water faucet that prevents a sudden increase in the water discharge amount caused by an abrupt operation.

Background Art

[0002] A conventional water faucet is of a type that adjusts a water discharge amount by vertically moving a lever handle serving as an operating member. This type of water faucet is mounted such that the lever handle protrudes from a faucet body, and the water discharge amount is adjusted by operating a distal end portion of the lever handle upward or downward. The lever handle of this water faucet rotates about a connection portion between the lever handle and the faucet body as a pivot. At this time, a stop valve located inside a cartridge on the faucet body side and directly or indirectly connected to the lever handle moves a distance corresponding to an operation angle of the lever handle, thereby opening and closing a water pipe inside the water faucet. This mechanism allows water to be discharged with a steplessly adjustable water discharge amount from the water faucet.

[0003] There is also a type of water faucet that adjusts the water discharge amount by twisting a so-called valve. This type of water faucet is mounted such that a faucet protrudes from the faucet body, and the faucet and an internal stop valve are connected by a spindle. The faucet body has a screw hole, and the spindle is provided with a threaded portion that matches the screw hole. When a user rotates the faucet, the spindle slightly moves in the vertical direction while rotating together with the valve. The stop valve moves vertically together with the spindle, thereby adjusting the opening and closing degree of the water pipe, allowing the user to achieve any desired water discharge amount.

[0004] Further, conventional water faucets of this type include those described in Japanese Patent Laid-Open No. 2023-004515 and Japanese Utility Model Registration No. 3231629.

Patent Document 1

[0006] However, conventional faucets have the following problems: The user needs to constantly monitor the water flow and adjust the angle of the lever handle or faucet accordingly. The relationship between the operating angle of the lever handle or faucet and the amount of water dispensed varies greatly from one faucet to another, depending on the internal structure of the faucet, the degree of internal deterioration over time, and the water pressure of the tap. In other words, it is difficult to intuitively understand the relationship between the angle of the lever handle or faucet and the amount of water dispensed, and therefore, rapidly operating the lever handle or similar can easily lead to excessive water flow. This can lead to problems such as water suddenly splashing around. Furthermore, if water is poured into a pot containing food, there is a problem of the contents splashing out.

[0007] This invention was conceived in view of the above circumstances, and aims to provide a faucet that prevents excessive water discharge even if the user suddenly operates the lever handle without checking the operating angle of the lever handle, prevents water from suddenly splashing around, and prevents the contents of a pot of food from splashing out when water is being poured into it. [Means for solving the problem]

[0008] The faucet according to the present invention is a faucet that can adjust the amount of water discharged by operating an operating tool, and has a part that holds a dilatant fluid and a part that receives the movement of the operating tool and transmits resistance to the operating tool by coming into contact with the fluid when the operating tool is at an angle greater than a certain value, so that when the operating tool is operated abruptly, the resistance from the dilatant fluid prevents a sudden discharge of water. [Effects of the Invention]

[0009] The faucet according to the present invention is a faucet in which the amount of water discharged can be adjusted by operating an operating tool, and has a part that holds a dilatant fluid and a part that receives the movement of the operating tool and transmits resistance to the operating tool by contacting the fluid when the operating tool is at an angle greater than a certain point, so that when the operating tool is operated abruptly, the resistance from the dilatant fluid prevents a sudden discharge of water, thus preventing water from splashing around when water is suddenly discharged, and preventing the contents of a pot or other container from splashing out.

[0010] Furthermore, the faucet is designed to adjust the water flow rate by rotating the operating device in the vertical direction.

[0011] Furthermore, the faucet is designed to adjust the water flow rate by rotating the operating device around a specific axis. [Brief explanation of the drawing]

MODE FOR CARRYING OUT THE INVENTION

[0013] The dilatant fluid, which is a main part of the water faucet according to the embodiment of the present invention, has shear thickening property, that is, it is a fluid that behaves like a liquid in response to a slow shear stimulus and exhibits resistance like a solid in response to a faster shear stimulus. As this dilatant fluid, for example, water-dissolved potato starch obtained by dissolving 1 part of potato starch in approximately 1 part of water is known. Cornstarch can also be used instead of potato starch. Note that the dilatant fluid is not limited to those made of the above potato starch or cornstarch, and may be made of other materials as long as it exhibits shear thickening property. Provided that, dilatant fluids obtained by mixing calcium carbonate, benzene and starch are not suitable for the faucet according to the present invention. This is because benzene has a high flammability hazard and is toxic, so it is not suitable for faucets that adjust the discharge rate of tap water.

[0014] The faucet 100 according to the first embodiment of the present invention is of a type that is opened by operating an external operating member, the lever handle 101, in an upward direction. The faucet 100 according to the first embodiment is a faucet capable of adjusting the water discharge amount by operating the lever handle 101, which is an external operating member of the faucet 100. The faucet internally includes: a dilatant fluid container 113 serving as a holding portion for holding a dilatant fluid 112; and a component that receives the motion of the external lever handle 101, contacts the dilatant fluid 112 when the angle of the lever handle 101 is equal to or greater than a predetermined angle, and transmits resistance to the lever handle 101. When the lever handle 101 is operated abruptly, sudden water discharge is blocked by the resistance from the dilatant fluid 112.

[0015] The "component that receives the motion of the external operating member, contacts the fluid when the angle of the operating member is equal to or greater than a predetermined angle, and transmits resistance to the operating member" corresponds to the connecting device 103, the dilatant fluid contact rod 108 and the like which will be described later.

[0016] As shown in Fig. 1 and other figures, the faucet 100 has a configuration in which the lever handle 101 serving as the operating member protrudes from an upper portion of the faucet main body 118, and is configured to discharge water when the lever handle 101 is operated in the upward direction. The faucet main body 118 is provided with a water supply passage 119 communicating with a water supply and a water discharge outlet 120 for discharging water.

[0017] A connecting device 103 is fixed to the back surface of the upper lid 102 of the lever handle 101. As shown in Figures 2(A) to 2(C), the connector 103 has a roughly T-shape in a horizontal orientation, with one end corresponding to the horizontal stroke fixed to the back surface of the upper cover 102 of the lever handle 101. The other end of the connector 103, corresponding to the horizontal stroke, is connected to a stopcock 115, which will be described later, and the end corresponding to the vertical stroke is connected to a dilatancy fluid contact rod 108, which will also be described later.

[0018] As shown in Figures 2(D) to 2(G), the dilatancy fluid contact rod 108 consists of a roughly rectangular parallelepiped head 104 and a rod tip 109 that protrudes from the lower surface of the head 104. The head 104 has a cavity 106 and a groove 122 to capture the vertical parallel movement of the connecting portion 105 that occurs when the connecting device 103 rotates, and the connecting portion 105 of the connecting device 103 is positioned so as to pass through the cavity 106 in the groove 122. The rod tip portion 109 is the part that comes into contact with the dilatant fluid 112 held in the dilatant fluid container 113, which will be described later.

[0019] The dilatant fluid container 113, which holds the dilatant fluid 112, is built into the faucet body 118 and is positioned further back from the user's perspective than the shut-off valve 115, which will be described later (see Figures 1, 4, and 5). The dilatancy fluid container 113 is formed in a bottomed cylindrical shape with an opening 110 on its upper surface into which the dilatancy fluid contact rod 108 can be inserted, and is configured so that the tip 109 of the dilatancy fluid contact rod 108 can come into contact with the central portion of the dilatancy fluid 112.

[0020] Furthermore, as shown in Figures 3(A) to 3(D), the stopcock 115 is composed of a head 121 and a bottom 117. The head 121 has an oval cavity 111 and a groove 123 formed therein to allow for the lateral parallel movement of the connecting portion 114 that occurs when the connecting device 103 rotates. The connection portion 114 of the connecting device 103 is positioned to penetrate the cavity 111 via a groove 123. Furthermore, the bottom portion 117 has a water supply channel 116 that is not connected to the water supply channel 119 when the faucet 100 is closed, as shown in Figure 1.

[0021] In the faucet 100, which is composed of the above-described components, when it is in a blocked state (see Figure 1), the stop valve 115 blocks the water supply channel 119 at its bottom surface 117, so no water is discharged.

[0022] When the lever handle 101 is pulled up, the dilatancy fluid contact rod 108 moves downward and the shut-off valve 115 moves parallel to the right inside the faucet. At this time, water flows partially through the water supply channel 119 and the water delivery channel 116, and through the water delivery channel 116 and the outlet 120, and the faucet 100 begins to discharge water. Simultaneously, the dilatancy fluid contact rod 108 descends toward the dilatancy fluid 112. When the lever handle 101 of the faucet 100 reaches a predetermined angle, the tip 109 of the dilatancy fluid contact rod 108 comes into contact with the fluid 112, as shown in Figure 5.

[0023] At this time, if the angle of the lever handle 101 changes rapidly, it is rapidly pushed in by the rod tip 109 of the dilatancy fluid contact rod 108. As a result, the dilatancy fluid 112 that the rod tip 109 contacts temporarily hardens, generating resistance to further angle changes of the lever handle 101 through the connection portion 105. From that point onward, the rod tip 109 of the dilatant fluid contact rod 108 remains in contact with the dilatant fluid 112, thus continuously generating resistance to any operation of the lever handle 101 that would increase the water discharge.

[0024] On the other hand, if the tip 109 of the fluid contact rod 108 comes into contact with the dilatant fluid 112 while the angle change of the lever handle 101 is slow, the dilatant fluid 112 will not harden, and no resistance will be felt when operating the lever handle 101. This means that even if the lever handle 101 is operated rapidly and receives resistance from the dilatant fluid 112, and then the lever handle 101 is operated slowly, no resistance from the dilatant fluid 112 will occur to the operation.

[0025] As described above, in the case of the faucet 100 according to the first embodiment of the present invention, if the upward operation of the lever handle 101 is sufficient to bring the tip 109 of the dilatant fluid contact rod 108 into contact with the dilatant fluid 112, the amount of water discharged will not increase rapidly, whether the operation is slow or rapid. However, if the lever handle 101 is operated abruptly and the tip 109 of the dilatant fluid contact rod 108 comes into sudden contact with the dilatant fluid 112, the sudden discharge of water will be prevented. On the other hand, even if the initial operation of the lever handle 101 is abrupt, if the operation is performed slowly after the tip 109 of the dilatant fluid contact rod 108 comes into contact with the dilatant fluid 112, the water will be discharged smoothly rather than abruptly.

[0026] The difference between the faucet 200 according to the second embodiment of the present invention and the faucet 100 according to the first embodiment described above is that the operation of the lever handle 201 for opening the valve is in the opposite direction to that of the lever handle 101 in the faucet 100 according to the first embodiment. That is, the faucet 200 according to the second embodiment is of the type that is opened by operating the lever handle 201, which is an external operating device, downwards.

[0027] As shown in Figure 6 and other figures, the faucet 200 according to this second embodiment has a lever handle 201, which is an operating device, that protrudes from the top of the faucet body 218, and is configured to dispense water when the lever handle 201 is operated downwards. The faucet body 218 is provided with a water supply channel 219 connected to the water supply and a spout 220 for discharging water.

[0028] A connecting device 203 is fixed to the underside of the top cover 202 of the lever handle 201. As shown in Figures 7(A) to 7(C), the connector 203 has a roughly T-shape in a horizontal orientation, with one end corresponding to the horizontal stroke fixed to the underside of the upper cover 202 of the lever handle 201. The other end of the connector 203, corresponding to the horizontal stroke, is connected to the stopcock 215, which will be described later, and the end corresponding to the vertical stroke is connected to the dilatancy fluid contact rod 208, which will be described later.

[0029] As shown in Figures 7(D) to 7(G), the dilatancy fluid contact rod 208 consists of a substantially rectangular parallelepiped head 204 and a rod tip 209 that protrudes from the lower surface of the head 204. The head 204 has a cavity 206 and a groove 222 to capture the vertical parallel movement of the connecting portion 205 that occurs when the connecting device 203 rotates, and the connecting portion 205 of the connecting device 203 is positioned so as to pass through the cavity 206 in the groove 222. The rod tip portion 209 is the part that comes into contact with the dilatant fluid 212 held in the dilatant fluid container 213, which will be described later.

[0030] The dilatancy fluid container 213, which holds the dilatancy fluid 212, is built into the faucet body 218 and, as shown in Figures 6, 9, and 10, is positioned in front of the shut-off valve 215 (described later) from the user's perspective of the faucet 200. The fact that this dilatancy fluid container 213 is positioned in front of the shut-off valve 215 is a major difference in configuration from the faucet 100 according to the first embodiment. The dilatancy fluid container 213 is formed in a bottomed cylindrical shape with an opening 210 on its upper surface into which the dilatancy fluid contact rod 208 can be inserted, and is configured so that the tip 209 of the dilatancy fluid contact rod 208 can come into contact with the central portion of the dilatancy fluid 212.

[0031] Furthermore, the stopcock 215 is composed of a head 221 and a bottom 217. The head 221 has an oval cavity 211 and a groove 223 formed therein to allow for the lateral parallel movement of the connecting portion 214 that occurs when the connecting device 203 rotates. The connection portion 214 of the connecting device 203 is positioned to penetrate the cavity 211 via a groove 223. Furthermore, the bottom portion 217 has a water supply channel 216 that does not connect to the water inlet 219 when the faucet 200 is closed, as shown in Figure 6, etc.

[0032] In the faucet 200, which is composed of the above-described components, when it is in a blocked state (see Figure 6), the stopcock 215 blocks the water supply channel 219 at its bottom surface 217, and no water is discharged.

[0033] When the lever handle 201 is pulled down, the dilatancy fluid contact rod 208 moves downward and the shut-off valve 215 moves to the left parallel inside the faucet. At this time, water flows partially through the water supply channel 219 and the water delivery channel 216, and through the water delivery channel 216 and the outlet 220, and the faucet 200 begins to discharge water. Simultaneously, the dilatancy fluid contact rod 208 descends toward the dilatancy fluid 212. When the lever handle 201 of the faucet 200 reaches a predetermined angle, the tip 209 of the dilatancy fluid contact rod 208 comes into contact with the dilatancy fluid 212 (see Figure 10).

[0034] At this time, if the angle of the lever handle 201 changes rapidly, it is rapidly pushed in by the rod tip 209 of the dilatancy fluid contact rod 208. As a result, the dilatancy fluid 212 that the rod tip 209 contacts temporarily hardens, generating resistance to further angle changes of the lever handle 201 through the connection portion 205. From that point onward, the rod tip 209 of the dilatant fluid contact rod 208 remains in contact with the dilatant fluid 212, thus continuously generating resistance to any operation of the lever handle 201 that would increase the water discharge.

[0035] On the other hand, if the angle change of the lever handle 201 is slow and the tip 209 of the dilatant fluid contact rod 208 comes into contact with the dilatant fluid 212, the dilatant fluid 212 will not harden, and no resistance will be felt when operating the lever handle 201. This means that even if the lever handle 201 is operated slowly after being subjected to resistance from the dilatant fluid 212 due to a sudden operation of the lever handle 201, no resistance to operation will occur.

[0036] As described above, in the case of the faucet 200 according to the second embodiment of the present invention, if the downward operation of the lever handle 201 is until the tip 209 of the dilatant fluid contact rod 208 comes into contact with the dilatant fluid 212, the amount of water discharged will not increase rapidly, whether the operation is slow or rapid. However, if the lever handle 201 is operated abruptly and the tip 209 of the dilatant fluid contact rod 208 comes into sudden contact with the dilatant fluid 212, the sudden discharge of water will be prevented. On the other hand, even if the initial operation of the lever handle 201 is abrupt, if the rod tip 209 of the dilatant fluid contact rod 208 comes into contact with the dilatant fluid 212 and is then operated slowly, the water will be discharged smoothly rather than abruptly.

[0037] The difference between the faucet 300 according to the third embodiment of the present invention and the faucet 100 according to the first embodiment and the faucet 200 according to the second embodiment described above is that the operating tool for opening the valve is not a lever handle 101 or 201, but rather a valve 305 which is an operating tool that adjusts the amount of water discharged by rotating it around a specific axis.

[0038] As shown in Figure 11 and other figures, the faucet 300 according to this third embodiment has a valve 305 connected to the outside of the faucet body 303 for the user to operate to adjust the amount of water discharge, and a shut-off valve 304 connected to the inside of the faucet body 303. The spindle 306, which has a spindle projection 310 near its center, is connected to the faucet body 303 by a screw-like structure. An upper packing 307 and a metal ring 308 are fixed to the faucet body 303 by an upper cover 309 at the part where the spindle 306 protrudes from the top of the faucet body 303 to the outside. A spindle contact portion 311 is located directly above the projection 310 in the middle of the spindle 306, and the contact portion 311 is connected to a dilatancy fluid contact portion 312 via a shaft 318. These 311, 318, and 312 constitute a dilatancy fluid contact device 317.

[0039] As shown in Figures 12(A) to 12(D), the dilatant fluid contact device 317 is fixed to the faucet body 303 by a bearing lateral hole 314 and a metal ring 316, so that it can only rotate around the shaft 318 relative to the faucet body 303. In this faucet body 303, the lower part, spaced apart from the dilatant fluid contact portion 312, is a dilatant fluid container 320 that holds the dilatant fluid 312. A metal ring 316 is placed around the shaft 318, and a fluid isolation packing 315 is placed next to it, preventing the dilatant fluid 313 from mixing with tap water.

[0040] In the faucet 300 according to the third embodiment configured in this way, when the user rotates the valve 305, the spindle 306 rotates together with the valve 305 and gradually rises relative to the faucet body 303. In conjunction with this, the shut-off valve 304 rises, connecting the water supply channel 301 and the spout 302, and water is discharged in a volume corresponding to the rotation angle of the valve 305 (see Figure 13). At the same time, the projection 310 rotates together with the spindle 306 and rises.

[0041] When the rotation angle of valve 305 reaches a predetermined value, the projection 310 contacts the spindle contact portion 311 of the dilatant fluid contact device 317, applying force and causing the dilatant fluid contact device 317 to rotate around the axis 318. The fluid contact portion 312 comes into contact with the dilatant fluid 313 due to this rotation (see Figure 14).

[0042] In this case, if the valve 305 rotates quickly, the dilatant fluid contact portion 312 rapidly pushes the dilatant fluid 313 in, causing the dilatant fluid 313 to temporarily harden and create resistance to further rotation of the dilatant fluid contact device 317. As a result, the valve 305 becomes difficult to rotate further because the protrusion 310 of the spindle 306 receives resistance from 311. On the other hand, even if the valve 305 rotates slowly, the dilatant fluid contact device 317 still touches the dilatant fluid 313, similar to the case of fast rotation, but because it pushes the dilatant fluid 313 at a low speed, the dilatant fluid 313 does not harden, and the valve 305 does not generate resistance to rotation that would further increase the water discharge volume.

Claims

1. A faucet that allows the amount of water discharged to be adjusted by operating a control device, characterized in that it has a part that holds a dilatant fluid and a part that receives the movement of the control device and, when the angle of the control device exceeds a certain angle, comes into contact with the fluid and transmits resistance to the control device, thereby preventing a sudden discharge of water by the resistance from the dilatant fluid when the control device is operated abruptly.

2. A faucet according to claim 1, characterized in that the amount of water discharged is adjusted by rotating the operating device in the vertical direction.

3. A faucet according to claim 1, characterized in that the amount of water discharged is adjusted by rotating the operating device around a specific axis.
