[0001] The present invention relates to a semi-automatic simple faucet and a simple handwashing device equipped with the simple faucet.

Background Art

[0002] Conventionally, various simple handwashing devices that enable handwashing with purified water even in places without water supply facilities have been disclosed (see, for example, Patent Documents 1 to 3). The simple handwashing device disclosed in Patent Document 1 has a water supply tank having a water supply cock disposed at the upper part of a frame body, a drainage receiving tank disposed at the lower part of this frame body, a water receiver disposed in the middle of this frame body, the water supply cock disposed on this water receiver, and a drain pipe vertically provided on this water receiver inserted and disposed in the drainage receiving tank. According to the simple handwashing device disclosed in this Patent Document 1, a water receiver for receiving supplied water is disposed in the middle of the frame body, and a drain pipe vertically provided on this water receiver is inserted and disposed in a drainage receiving tank disposed at the lower part of the frame body to store drainage, so that when used as an outdoor water supply facility or handwashing facility, etc., it does not stain the ground and is optimal as an outdoor leisure item. Also, since it can be configured simply by disposing only a water supply tank, a water receiver, and a drainage receiving tank in a framework, it can be provided as an inexpensive product with a very simple structure and low manufacturing cost.

[0003] Furthermore, the simple hand-washing device disclosed in Patent Document 2 is characterized by comprising a washbasin support supported by caster-equipped legs, a wastewater tank installed at the lower part of the washbasin support in communication with the drain of the washbasin support, a water tower erected on the washbasin support with a water supply tank positioned at its top, and a plurality of shower hoses arranged on the outer wall surface of the water tower in communication with the water supply tank and being flexible, with openable and closable shower heads provided at the ends of the hoses.According to the simple hand-washing device disclosed in Patent Document 2, in situations such as meal times when many users must wash their hands at once, such as in nursing homes and medical facilities, it can be easily moved to a location where sufficient space can be secured, and because the washbasin support is circular in shape, it is possible for many people to wash their hands at once, and for changes of shifts to be carried out efficiently without congestion.

[0004] Furthermore, the water supply device disclosed in Patent Document 3 is characterized by comprising a cylindrical water container having an opening fitted with an openable and closable stopper, a container holder below which the body of the water container is held vertically, and a water container receiver below the container holder which receives the vicinity of the opening of the water container, the stopper being a bottomed cylinder with a female thread on its inner surface, a drain pipe penetrating the bottom of the cylinder with a valve fixed at its upper end, a hole which is a water inlet below the valve and on the side of the drain pipe, the lower end of the drain pipe penetrating the bottom of the cylinder and protruding outward, a hook rod fixed to the side of the protruding drain pipe, a claw on the outside of the bottom of the bottomed cylinder, a water splash prevention wall with an opening on its outer circumference so that the stopper is positioned approximately in the center and surrounded, and a water receiving base with a drain at the lower end of the water splash prevention wall.According to the water supply device disclosed in Patent Document 3, a water supply device that can replace a water supply can be moved and installed in any desired location, and water can be provided in places where there is no water supply. [Prior art documents] [Patent Documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 9-19381 [Patent Document 2] Japanese Patent Publication No. 2008-200394 [Patent Document 3] Patent No. 4927984 [Overview of the Initiative] [Problems that the invention aims to solve]

[0006] According to the simple hand-washing devices disclosed in Patent Documents 1 to 3, it is believed that even in locations without water supply facilities, hand-washing facilities using purified water can be easily provided by moving and installing these simple hand-washing devices.

[0007] However, the simple hand-washing device disclosed in Patent Document 1 requires opening a water supply tap to discharge water from the water tank, and closing the tap after washing hands. Similarly, the simple hand-washing device disclosed in Patent Document 2 also requires opening and closing a lever when washing hands with water from the water tank. In other words, after washing hands thoroughly, it is necessary to touch the water supply tap or lever to close the valve, which is not necessarily a desirable configuration from a hygienic standpoint.

[0008] In the water supply device disclosed in Patent Document 3, water can be dispensed from the water container while the drain pipe is being held up by hand, or while the hook attached to the drain pipe is hooked onto the fingernail. When the hand holding the drain pipe is released, or when the hook is released from the fingernail, the water pressure causes the drain pipe to move downward and close the valve, which is considered to be superior in terms of hygiene compared to the simple hand-washing devices disclosed in Patent Documents 1 and 2. In addition, when the hand holding the drain pipe is being held up, closing the valve is possible simply by releasing the hand, making it convenient.

[0009] However, washing hands while holding the drainpipe in place would be extremely difficult because both hands would not be fully usable. In contrast, if the hook is attached to the fingernail, both hands would be fully usable, allowing for normal two-handed handwashing. However, even while removing the hook from the fingernail after washing hands, water would still be discharged from the drainpipe, resulting in some waste, however small.

[0010] It goes without saying that water is extremely precious, especially in evacuation shelters during disasters. Drinking water is essential, of course, but hygiene management, such as handwashing after using the toilet, is also crucial, and it's necessary to minimize waste as much as possible. While various methods for effectively utilizing expired disaster relief drinking water are being considered and implemented in some cases, the reality is that it's still being discarded. Therefore, methods to reduce waste and utilize the water effectively are desired.

[0011] Therefore, in view of the above-mentioned problems, the inventors of this invention have diligently studied and developed a simple water tap with a very simple configuration that minimizes waste of purified water while semi-automating the dispensing process, and a simple hand-washing device equipped with this simple water tap that can effectively utilize, for example, expired emergency drinking water, resulting in the present invention. [Means for solving the problem]

[0012] In other words, the simple water tap of the present invention comprises a cylindrical water passage pipe and a valve portion formed at the upper end of the water passage pipe, a nozzle body having a water guide hole formed on the upper end side of the water passage pipe, and a receiving member having an insertion hole through which the water passage pipe is inserted, characterized in that when the water passage pipe is inserted into the insertion hole and the valve portion moves toward the receiving member, the water guide hole is positioned within the insertion hole.

[0013] Furthermore, the present invention is characterized in that a resistance member is provided in the valve portion of the simple water tap.

[0014] Furthermore, the present invention comprises a simple water tap according to the present invention described above, and a box-shaped hand-washing device body, wherein the inside of the hand-washing device body is divided into upper and lower sections by a partition wall, with a hand-washing chamber formed on the lower side of the partition wall and a water storage tank formed on the upper side of the partition wall, a through hole formed in the partition wall, the receiving member disposed in the through hole, and the water supply pipe provided by the nozzle body inserted into the through hole from above the receiving member.

[0015] Furthermore, the present invention provides a simple hand-washing device characterized in that a PET bottle receiving plate is provided in the water storage tank, and the PET bottle receiving plate is provided with a PET bottle insertion hole.

[0016] Furthermore, the present invention comprises a simple faucet according to the present invention as described above, a storage cylinder on which the simple faucet is installed, a PET bottle mounting cylinder for attaching a PET bottle, and a water guide pipe connecting the water storage cylinder and the PET bottle mounting cylinder, wherein a through hole is formed in the bottom plate of the water storage cylinder, and the receiving member is disposed on the bottom plate inside the water storage cylinder such that the through hole and the insertion hole provided in the receiving member are in communication, and the water passage pipe provided in the nozzle body is inserted from above the receiving member through the insertion hole and the through hole, and when the valve portion provided in the nozzle body moves toward the receiving member, the inlet of the water guide pipe on the storage cylinder side is blocked by the valve portion.

[0017] Furthermore, the present invention provides a simple hand-washing device characterized in that a rod-shaped member is erected on the bottom plate inside the PET bottle mounting cylinder. [Effects of the Invention]

[0018] The present invention provides a simple faucet that, despite its extremely simple configuration, can semi-automate water discharge while minimizing waste of purified water. In particular, the faucet can be easily opened by simply pushing up the water passage pipe of the nozzle body that constitutes the simple faucet, and closed by simply releasing the water passage pipe. This makes it easy to open and close, and also provides a simple faucet that is hygienic.

[0019] In addition, in the simple faucet of the present invention, by disposing a resistance member in the valve portion, the time from the open state to the closed state can be adjusted, and the discharge amount of purified water can be easily adjusted. <00​​​​​​​​​​​​​​​​​​​​​(a) is a front view of a simple handwashing device equipped with a simple faucet according to an embodiment of the present invention, and (b) is a plan view.

Embodiments for Carrying out the Invention

[0025] Hereinafter, embodiments of the simple faucet of the present invention and a simple handwashing device equipped with this simple faucet will be described in detail based on the drawings. Fig. 1(a) is a front view showing a simple handwashing device 1 equipped with a simple faucet 2 according to an embodiment of the present invention, and Fig. 1(b) is a plan view of the simple handwashing device 1. Also, Figs. 3(a) to (f) show a nozzle body 11 constituting the simple faucet 2 according to an embodiment of the present invention, and Figs. 4(a) to (c) show a receiving member 12 constituting the simple faucet 2 according to an embodiment of the present invention.

[0026] First, as shown in Figure 3, the nozzle body 11 constituting the simple faucet 2 according to one embodiment of the present invention comprises a cylindrical water passage pipe 13 and a valve portion 14 formed at the upper end of the water passage pipe 13. A water guide hole 15 is formed on the upper end side of the water passage pipe 13 and communicates with the water passage 13a inside the water passage pipe 13. In this embodiment, the water passage pipe 13 and the valve portion 14 are molded integrally, but they may also be formed by preparing the water passage pipe 13 and the valve portion 14 separately and then integrating them. Furthermore, the external shape of the water passage pipe 13 and the valve portion 14 in plan view is not limited to a circular shape, but can be appropriately selected as an elliptical or rectangular shape, etc.

[0027] Furthermore, the receiving member 12 constituting the simple faucet 2 of this embodiment is an annular member having an insertion hole 16 through which the water passage pipe 13 related to the nozzle body 11 is inserted, and a flange portion 12a is formed at the upper end of the receiving member 12, which is larger in diameter than the lower end. Note that the external shape of the receiving member 12 in plan view according to this embodiment is not limited to a circular shape, but may be elliptical, rectangular, etc., and the external shape of the insertion hole 16 in plan view is also appropriately selected to match the external shape of the water passage pipe 13 in plan view.

[0028] The simple faucet 2 of this embodiment is constructed by combining a nozzle body 11 and a receiving member 12. Specifically, as shown in Figure 5(a), the simple faucet 2 is formed by inserting the water passage pipe 13 provided by the nozzle body 11 into the insertion hole 16 provided by the receiving member 12. In the simple faucet 2 of this embodiment, when the water passage pipe 13 related to the nozzle body 11 is inserted from above into the insertion hole 16 related to the receiving member 12, and the valve portion 14 related to the nozzle body 11 moves towards the receiving member 12, the water guide hole 15 related to the nozzle body 11 is positioned inside the insertion hole 16 related to the receiving member 12. The opening and closing operations of the simple faucet 2 of this embodiment will be explained in the simple hand-washing device 1 according to the following embodiment of the present invention.

[0029] Next, a simple hand-washing device 1 according to one embodiment of the present invention will be described in detail. As shown in Figures 1 and 2, the simple hand-washing device 1 according to this embodiment mainly consists of a simple faucet 2 according to the above embodiment and a box-shaped hand-washing device body 3.

[0030] In this embodiment of the simple hand-washing device 1, the hand-washing device body 3 is box-shaped with a rectangular external shape in plan view, and the inside of the hand-washing device body 3 is divided into upper and lower sections by a partition wall 4. A hand-washing chamber 5 is formed on the lower side of the partition wall 4 that divides the inside of the hand-washing device body 3 into upper and lower sections, and a water storage tank 6 is formed on the upper side of the partition wall 4.

[0031] An opening 7 is formed in the side wall of the handwashing device body 3 where the handwashing room 5 is located. Hands can be inserted into the handwashing room 5 inside the handwashing device body 3 through this opening 7, and hands can be washed by opening the simple faucet 2 located above the handwashing room 5. A drain pipe 20 is located below the handwashing room 5, and the purified water discharged into the handwashing room 5 is drained to the outside. A sloping floor plate 21 is also located below the handwashing room 5 to improve the drainage efficiency from the drain pipe 20.

[0032] Purified water is stored in a water tank 6 formed on the upper side of the partition wall 4 related to the handwashing device body 3. The purified water stored in this water tank 6 is discharged into the handwashing room 5 formed on the lower side of the partition wall 4 by opening the simple faucet 2. In this embodiment, a PET bottle receiving plate 22 is provided in the water tank 6 of the simple handwashing device 1. This PET bottle receiving plate 22 has multiple PET bottle insertion holes 23 into which the mouth of a PET bottle can be inserted when the PET bottle is upside down. Therefore, for example, if a bottle of mineral water has expired, the cap of the mineral water bottle can be removed and the mouth of the PET bottle can be inserted into the PET bottle insertion holes 23 of the PET bottle receiving plate 22, thereby storing the mineral water in the water tank 6 and effectively utilizing it as purified water for handwashing.

[0033] In this embodiment, the PET bottle receiving plate 22 is installed on a receiving plate support member 24 located inside the water storage tank 6, but the method of installing the PET bottle receiving plate 22 is not particularly limited. Furthermore, a partition wall 25 corresponding to the position of the PET bottle insertion hole 23 is erected on the upper surface of the PET bottle receiving plate 22, making it easy to prevent the PET bottle from tipping over when the mouth of the PET bottle is inserted into the PET bottle insertion hole 23.

[0034] The simple hand-washing device 1 of this embodiment is provided by attaching a simple faucet 2 to the hand-washing device body 3, which has the above configuration. In this embodiment, a through hole 8 is formed in the center of the partition wall 4 of the hand-washing device body 3, into which the lower end of a receiving member 12 related to the simple faucet 2 can be inserted. The receiving member 12 is inserted from above the through hole 8 and the flange portion 12a related to the receiving member 12 is locked to the outer peripheral edge of the through hole 8, thereby attaching the receiving member 12 to the through hole 8. In this embodiment, an O-ring 19 is provided on the lower side of the partition wall 4 at the outer peripheral edge of the through hole 8 to prevent the receiving member 12 attached to the through hole 8 from coming off and to prevent water leakage from the water tank 6.

[0035] Then, the installation of the simple faucet 2 to the handwashing device body 3 is completed by inserting the water passage pipe 13, which is provided on the nozzle body 11 of the simple faucet 2, into the insertion hole 16 from above the receiving member 12.

[0036] The handwashing method using the simple handwashing device 1 of this embodiment, which has the above configuration, will be described below. First, the simple handwashing device 1 of this embodiment is installed at the place of use, and purified water is stored in the water tank 6 related to the handwashing device body 3. The purified water stored in the water tank 6 is not particularly limited, and if ordinary tap water is available, it may be tap water. However, for example, bottled mineral water that has been stockpiled at evacuation centers during disasters and has passed its expiration date may not be suitable for drinking, but it can be used for handwashing, so by using such mineral water, the effective use of expired stockpiled goods can be achieved.

[0037] When purified water is stored in the water tank 6, as shown in Figure 5(a), the water pressure pushes the nozzle body 11 of the simple faucet 2 downward, causing the valve portion 14 of the nozzle body 11 to contact the upper surface of the receiving member 12, and the water guide hole 15 of the nozzle body 11 to be positioned inside the insertion hole 16 of the receiving member 12, thereby closing the simple faucet 2.

[0038] Then, the user inserts their hand into the handwashing chamber 5 of the handwashing device body 3 through the opening 7 and uses their inserted hand to push up the water passage pipe 13 of the nozzle body 11 of the simple faucet 2. When the water passage pipe 13 is pushed up and the nozzle body 11 moves upward, as shown in Figure 5(b), a gap is created between the valve part 14 of the nozzle body 11 and the receiving member 12, and the water guide hole 15 formed in the water passage pipe 13 is exposed into the water storage tank 6. As a result, the water storage tank 6, the water guide hole 15, the water passage 13a in the water passage pipe 13, and the handwashing chamber 5 are connected, i.e., the valve is open, and purified water from the water storage tank 6 is discharged into the handwashing chamber 5.

[0039] Therefore, if the nozzle body 11 is moved upward and the water guide hole 15 related to the water passage pipe 13 is kept exposed in the water storage tank 6, the simple faucet 2 will remain open, and purified water from the water storage tank 6 will continue to be discharged into the handwashing room 5. On the other hand, if the nozzle body 11 is moved upward and the water guide hole 15 related to the water passage pipe 13 is released from the state in which it is exposed in the water storage tank 6, the nozzle body 11 will gradually descend due to water pressure, and eventually the valve part 14 related to the nozzle body 11 will come into close contact with the receiving member 12, resulting in a closed state and stopping the discharge of purified water.

[0040] As described above, with the simple hand-washing device 1 equipped with the simple faucet 2 of this embodiment, the faucet can be easily opened by simply pushing up the water passage pipe 13 related to the nozzle body 11 that constitutes the simple faucet 2, and purified water from the water storage tank 6 can be discharged into the hand-washing room 5.

[0041] Furthermore, by simply releasing one's hand from the water supply pipe 13, the nozzle body 11 can be gradually lowered by water pressure and eventually closed, and after opening, one can release one's hand from the water supply pipe 13. Therefore, both hands can be used freely while the device is discharging purified water into the handwashing room 5, allowing for handwashing. Moreover, since there is no need to perform a closing operation, the user does not need to touch the nozzle body 11 or other parts again with their clean hands, thus providing a hygienic and simple handwashing device 1.

[0042] In this embodiment, the simple faucet 2 has a resistance member 17 disposed on the upper surface of the valve portion 14 related to the nozzle body 11. The resistance member 17 in this embodiment is a disc-shaped stainless steel plate, and in this embodiment, it is attached to the upper surface of the valve portion 14 with screws 18. By providing this resistance member 17, the time from the open state to the closed state can be adjusted, and as a result, the amount of purified water discharged can be adjusted. In other words, by providing the resistance member 17, it acts as resistance when the nozzle body 11 descends, so the amount of purified water discharged can be easily adjusted by arbitrarily setting the size and shape of the resistance member 17, and the discharge amount can be easily adjusted simply by replacing the resistance member 17. For example, if the horizontal area of ​​the resistance member 17 is increased, the resistance when the nozzle body 11 descends will increase, so the descent speed will be slower, and as a result, the discharge amount can be increased, and a sufficient discharge amount can be secured with a single opening operation. On the other hand, reducing the horizontal area of ​​the resistance member 17 reduces the resistance when the nozzle body 11 descends, thus increasing the descent speed and suppressing the discharge volume, thereby saving water. The shape, material, and mounting method of the resistance member 17 are not limited to the embodiments described above. For example, the shape may be disc-shaped, elliptical, rectangular, etc., and the material may be a rubber sheet, etc., and can be appropriately selected according to the discharge volume, usage period, and the planar shape of the hand-washing device body 3.

[0043] Next, a simple hand-washing device 30 according to another embodiment of the present invention will be described in detail. As shown in Figures 6 to 8, the simple hand-washing device 30 according to this embodiment mainly consists of a simple faucet 2 according to the above-described embodiment, a storage cylinder 31 on which the simple faucet 2 is installed, a PET bottle mounting cylinder 32 for attaching PET bottles, and a water guide pipe 33 connecting the storage cylinder 31 and the PET bottle mounting cylinder 32. In the simple hand-washing device 30 of this embodiment, as shown in Figure 6(b), the storage cylinder 31 is installed in the center, and four PET bottle mounting cylinders 32 are installed around it, with each PET bottle mounting cylinder 32 and the storage cylinder 31 connected by the water guide pipe 33. However, the number of PET bottle mounting cylinders 32, the positional relationship between the storage cylinder 31 and the PET bottle mounting cylinders 32, etc., are not particularly limited. Furthermore, although the storage cylinder 31 and the PET bottle mounting cylinders 32 according to this embodiment are attached to a stand 34, the shape of the stand and the method of attachment to the stand are not particularly limited, as long as the simple faucet 2 can be installed at a height sufficient for hand-washing.

[0044] In the simple hand-washing device 30 of this embodiment, a simple faucet 2 is provided in the storage cylinder 31. Specifically, a through hole 36 is formed in the bottom plate 35 of the water storage cylinder 31, and a receiving member 12 is provided on the bottom plate 35 inside the storage cylinder 31 with the through hole 36 and an insertion hole 16 (see Figure 4) provided in the receiving member 12 related to the simple faucet 2 in communication. The simple faucet 2 is then provided in the storage cylinder 31 by inserting the water passage pipe 13 provided in the nozzle body 11 related to the simple faucet 2 into the insertion hole 16 and the through hole 36 from above the receiving member 12. A lid 39 is provided in the storage cylinder 31. Although purified water for hand washing is not pre-stored in the storage cylinder 31 according to this embodiment, the lid 39 is provided to keep the inside of the storage cylinder 31 more hygienic.

[0045] The PET bottle mounting cylinder 32 according to this embodiment is configured to allow the PET bottle to be mounted upside down by its mouth P. In the simplest configuration, the upside-down PET bottle mouth P is inserted through the upper opening of the PET bottle mounting cylinder 32, and the PET bottle is supported by the upper opening edge 32a of the PET bottle mounting cylinder 32. However, PET bottles come in various sizes, such as 500ml and 2L, and larger sizes may tip over. Therefore, in the PET bottle mounting cylinder 32 according to this embodiment, a rod-shaped member 38 is erected on the bottom plate 37 inside the PET bottle mounting cylinder 32. When mounting a PET bottle into the PET bottle mounting cylinder 32, the rod-shaped member 38 is inserted into the PET bottle from the mouth P, making it easy to prevent the PET bottle from tipping over.

[0046] In the simple hand-washing device 30 of this embodiment, a storage cylinder 31 equipped with a simple water tap 2 and a PET bottle mounting cylinder 32 are connected by a water guide pipe 33. Specifically, one end of the water guide pipe 33 is connected to the lower part of the PET bottle mounting cylinder 32, and this end of the water guide pipe 33 becomes an outlet 40 from the PET bottle mounting cylinder 32 to the water guide pipe 33. The other end of the water guide pipe 33 is connected to the lower part of the storage cylinder 31, and this other end of the water guide pipe 33 becomes an inlet 41 from the water guide pipe 33 to the storage cylinder 31.

[0047] In particular, the position of the inlet 41 is important in the simple hand-washing device 30 of this embodiment. Specifically, the inlet 41 is configured to be closed by the valve portion 14 of the nozzle body 11 related to the simple faucet 2 installed in the storage cylinder 31 when the valve portion 14 moves to the receiving member 12 side and is in a tight seal. When the inlet 41 is closed by the valve portion 14, the simple faucet 2 is in a closed state.

[0048] The handwashing method using the simple handwashing device 30 of this embodiment, which has the above configuration, will be described below. First, the simple handwashing device 30 of this embodiment is installed at the place of use, and a plastic bottle containing purified water is attached to the plastic bottle attachment cylinder 32. As for the purified water used here, as with the embodiment described above, bottled mineral water that has been stockpiled at evacuation centers during disasters and has passed its expiration date is useful.

[0049] When a plastic bottle is attached to the plastic bottle mounting cylinder 32, purified water flows out of the plastic bottle and into the water intake pipe 33 from the outlet 40. However, as shown in Figure 7, the nozzle body 11 of the simple faucet 2 is tightly attached to the receiving member 12 due to its own weight, and the inlet 41 on the storage cylinder 31 side of the water intake pipe 33 is blocked by the valve part 14 of the receiving member 12, so the simple faucet 2 is in a closed state.

[0050] Then, the water passage pipe 13 related to the nozzle body 11 of the simple water tap 2 is pushed up. As the water passage pipe 13 is pushed up and the nozzle body 11 moves upward, as shown in Figure 8, a gap is created between the valve part 14 related to the nozzle body 11 and the receiving member 12, and the water guide hole 15 formed in the water passage pipe 13 is exposed above the receiving member 12. Furthermore, the inlet 41 related to the water guide pipe 33, which was blocked by the valve part 14, is opened, so the PET bottle mounting cylinder 32, the water guide pipe 33, the inside of the storage cylinder 31, the water guide hole 15, and the water passage 13a inside the water passage pipe 13 are connected, that is, the valve is opened, and purified water in the PET bottle is discharged from the water passage pipe 13.

[0051] Therefore, in the simple hand-washing device 30 of this embodiment, if the nozzle body 11 is moved upward and the water guide hole 15 related to the water passage pipe 13 is kept exposed above the receiving member 12 inside the storage cylinder 31, the simple faucet 2 is kept open, and purified water in the PET bottle continues to be discharged from the water passage pipe 13. On the other hand, if the hand is released from the state in which the nozzle body 11 is moved upward and the water guide hole 15 related to the water passage pipe 13 is exposed above the receiving member 12, the nozzle body 11 gradually descends due to its own weight, and eventually the valve part 14 related to the nozzle body 11 comes into close contact with the receiving member 12, resulting in a closed state and stopping the discharge of purified water.

[0052] As described above, with the simple hand-washing device 30 equipped with the simple faucet 2 of this embodiment, similar to the simple hand-washing device 1 of the embodiment described above, the faucet 2 can be easily opened by simply pushing up the water passage pipe 13 related to the nozzle body 11 that constitutes the simple faucet 2 by hand, and purified water from the PET bottle can be discharged.

[0053] Furthermore, by simply releasing one's hand from the water supply pipe 13, the nozzle body 11 gradually descends under its own weight and eventually closes, and after opening, one can release their hand from the water supply pipe 13. Therefore, both hands are free to use while purified water is being discharged, allowing for hand washing. Moreover, since there is no need to perform a closing operation, the user does not need to touch the nozzle body 11 or other parts again with their clean hands, thus providing a hygienic and simple hand-washing device 30.

[0054] Furthermore, in the simple hand-washing device 30 of this embodiment, there is no need to store the purified water in the PET bottle in the storage cylinder 31, and by opening the simple faucet 2, the water can be dispensed directly from inside the PET bottle, thus providing a simple hand-washing device that is even more hygienic.
