However, basins used in facilities such as hospitals and nursing homes have the following problems.
That is, in the conventional wash basin such as Patent Document 1 described above, a cleaning liquid, a disinfecting liquid, a toilet tool used by a user, and the like are cluttered on the counter, and moisture has collected around the placed object indefinitely. As a result, microorganisms propagated and germs increased. And in hospitals and other facilities, there are many facilities where it is difficult to secure enough space to install separate washbasins for users to live and hand-washing equipment such as medical staff and nursing staff. Therefore, it is common for users and staff to use a wash basin. For this reason, if a staff member who is in contact with many patients or elderly people in the facility uses a wash basin that also serves as a user, germs will adhere to the hands and arms despite hand washing, and the staff will transfer to the user. There was a problem of being infected.
In addition, as in Patent Document 1, the structure is designed for the convenience of the user, and since it is a wash basin intended for use in hand washing or face washing, it is a hand washing facility dedicated to staff. In addition, there has been a demand for a suitable basin that does not allow microorganisms to propagate.

The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a hand-washing machine capable of preventing infection from a staff to a user.
Another object of the present invention is to provide a handwasher that can be installed in a narrow space.

In order to achieve the above object, the hand-washing machine according to the present invention is provided with a bowl portion that is formed in a concave shape and has a drain hole on its bottom surface, a faucet portion that supplies cleaning water to the bowl portion, and a lower portion of the bowl portion. The bowl portion has a rear end surface in the depth direction supported by the wall and a bottom surface inclined downward toward the drain hole. It is formed in a surface shape, and the outer peripheral upper end edge is formed to be inclined or curved downward toward the bottom surface.
In the present invention, the bottom surface and the outer peripheral upper edge of the bowl part have no horizontal flat part and concave part (dent part), and have a surface shape in which water flows toward the drain hole of the bowl part. The water is not collected. In addition, since the upper edge of the outer periphery is not a flat surface, it is not possible to place an object such as a cleaning solution in a stable state, so that it is not possible to place an object on the upper edge of the outer periphery, and the state where water accumulates around the object can be eliminated. it can. For this reason, microorganisms do not propagate from the water accumulated in the bowl portion, and it is possible to prevent bacteria from adhering to the staff during hand washing.

Moreover, in the hand-washing machine which concerns on this invention, it is preferable that the faucet part is provided in the wall with the predetermined separation distance in the base end part upwards from the bowl part.
In the present invention, since a gap is provided between the faucet part and the bowl part, a space on the bowl part is ensured, and the upper surface of the bowl part can be easily cleaned. In addition, since no protruding member such as a faucet part is disposed on the upper surface of the bowl part, it is possible to eliminate the occurrence of germs due to accumulation of water around the protruding part.

According to the hand wash basin of the present invention, since there is no horizontal flat part and a concave part (dent part) in the bowl part and an object cannot be placed on the upper part of the bowl part, water always remains on the upper part of the bowl part. There is no accumulation. Therefore, microorganisms do not propagate from the water accumulated in the bowl part, and it is possible to prevent bacteria from adhering to the staff during hand washing, and to prevent infection from the staff to the user.
In addition, according to the handwasher of the present invention, since it has a compact structure without a counter or the like that can place objects around the bowl part as in the prior art, the handwasher can be installed even in a narrow space in the facility Therefore, it is possible to install a hand-washing device dedicated to the staff separately from the wash-basin used by users such as hospital patients.

Hereinafter, the hand-washing machine by this invention is demonstrated based on FIG. 1 thru | or FIG.
1 is a front view of a hand-washing machine according to an embodiment of the present invention, FIG. 2 is a side view of the hand-washing machine shown in FIG. 1, FIG. 3 is a plan view of the hand-washing machine shown in FIG. FIG.

  The hand-washing machine 1 according to the present embodiment shown in FIGS. 1 to 3 is used in facilities such as hospitals and nursing homes by medical staff and nursing staff (hereinafter simply referred to as “staff”). Separately from elderly people, etc.), it is a facility for hand washing.

  This hand-washing machine 1 includes a bowl portion 2 formed in a concave shape, a faucet fitting 3 (water faucet portion) for supplying washing water into the bowl portion 2, and drainage formed on the bottom surface 2 d of the bowl portion 2. A drainage pipe 4 (drainage part) is provided in communication with the hole 2c.

  As shown in FIGS. 2 and 3, the bowl portion 2 is supported by a rear end surface 2 a in the depth direction being in contact with, for example, a wall 5 of a building, and the connection portion T forms a continuous surface. . The connecting portion T between the bowl portion 2 and the wall 5 is installed in close contact with the wall surface, and is formed in a surface shape that is smooth without any joints or irregularities and inclined downward toward the bottom surface 2d.

  The bowl portion 2 is a material having a strong anti-corrosion property even when exposed to water, chemicals, etc., and having a smooth and rigid surface on which mold and dirt are hard to be fixed, such as artificial marble. It is made of material. The drain hole 2 c is provided at the lowermost part of the bottom surface 2 d and substantially at the center in plan view, and communicates with the drain pipe 4.

  As shown in FIG. 4, the outer peripheral upper end edge 2b of the bowl portion 2 has a surface shape that is inclined or curved downward toward the bottom surface 2d side. The outer peripheral upper edge 2b is formed so as to be smoothly continuous with the bottom surface 2d. The outer peripheral upper edge 2b is formed to have a thickness dimension such as a cleaning liquid or a fixture necessary for hand washing, such as a thickness dimension of, for example, 12 mm to 13 mm.

  The bottom surface 2d of the bowl part 2 is formed in a surface shape having a smooth curved surface from the outer peripheral upper end edge 2b toward the drain hole 2c located at the lowermost part of the bottom surface 2d. That is, the surface shape on the upper surface of the bowl part 2 is a shape without a horizontal flat part (plane part) and a recessed part (dent part). This is configured in such a way that all the water during and after hand washing by the staff flows down toward the drain hole 2c so that water droplets (moisture) do not accumulate in the bowl portion 2.

  As shown in FIGS. 1 to 3, the outer peripheral upper end edge 2 b of the bowl portion 2 excluding the rear end face 2 a supported by the wall 5 is in an open state. Therefore, the hand-washing machine 1 can be made smaller as compared with a hand-washing machine provided with a counter that can place objects around the bowl part 2 as in the prior art. It has a possible configuration.

  The lower surface 2e on the lower side of the bowl portion 2 has a shape having substantially the same curved surface as the bottom surface 2d, and a curved surface that is smoothly continuous from the outer peripheral upper end edge 2b toward the position where the drain pipe 4 is provided is formed. ing.

  The faucet fitting 3 is disposed with its base end portion 3a supported by the wall 5 with a predetermined separation distance upward from the bowl portion 2, and the supply port 3b facing the bottom surface 2d. Here, the predetermined separation distance is a distance that is less affected by water splashing on the bottom surface 2d.

The faucet fitting 3 employs an automatic faucet in which the amount of washing water and the water temperature are automatically adjusted in advance. This is of a known configuration in which a sensor (not shown) is provided near the supply port 3b of the faucet fitting 3, and when the hand is placed close to the sensor, the sensor reacts and water is discharged for a certain period of time. It is said. Although not specifically shown, a single-lever mixing faucet that can easily adjust the amount and temperature of washing water by moving the lever up and down or rotating may be adopted instead of the automatic faucet type. Also in this case, for example, the faucet fitting 3 can be easily operated near a wrist that is not wet without being touched by a wet hand after hand washing.
Such a faucet fitting 3 is connected to a water supply pipe 32 and a hot water supply pipe 33 via a pipe 31 for supplying cleaning water, and the water supply pipe 32 and the hot water supply pipe 33 support the bowl portion 2 in advance. It is embedded and arranged inside the arranged wall 5.

The drainage pipe 4 communicates with the drainage hole 2c of the bowl part 2 and is disposed below the bowl part 2, and the tip of the drainage pipe 4 is inward of the wall 5 that supports the bowl part 2 in the same manner as the water supply pipe and the hot water supply pipe. Embedded in.
And since the drain pipe 4, the water supply pipe 32, and the hot water supply pipe 33 are embedded in the wall 5, the open space 6 is formed under the bowl part 2 (refer FIG.1 and FIG.2).

  Further, in the present embodiment, the bowl portion 2 is not provided with a drain plug for storing water or an overflow portion. This is because the purpose of use of the handwashing machine 1 is dedicated to hand-washing by staff, and there is a possibility that a person who adheres to the fingers the bacteria that will become a nosocomial infection source will not be stored in the bowl part 2 According to this, the drain hole 4 is not provided with an open / close stopper or an overflow part.

  As described above, in the hand-washing machine 1, the bottom surface 2 d and the outer peripheral upper edge 2 b of the bowl portion 2 do not have a horizontal flat portion and a concave portion (a hollow portion), so Since it flows toward the drain hole 2c, the water does not accumulate. Further, since the upper edge of the outer periphery is not a flat surface, it is impossible to place an object such as a cleaning liquid used for hand washing, so that water does not accumulate around the object. For this reason, in the hand washing machine 1, microorganisms do not propagate from the water accumulated in the bowl portion, and it is possible to prevent bacteria from adhering to the staff during hand washing.

  In addition, since the faucet fitting 3 is disposed at a position spaced apart from the bowl portion 2 by a predetermined distance, a gap is provided between the faucet fitting 3 and the bowl portion 2, and the space above the bowl portion 2. S (see FIGS. 1 and 2) is ensured, and the upper surface of the bowl portion 2 can be easily cleaned. In addition, since no protruding member such as the faucet fitting 3 is disposed on the upper surface of the bowl portion 2, it is possible to eliminate the occurrence of germs due to accumulation of water around the protruding portion.

In the hand-washing machine 1 according to the present embodiment described above, the bowl portion 2 has no horizontal flat portion and concave portion (indentation portion) and cannot be placed on the upper portion of the bowl portion 2. There will be no accumulation of water at the top of the forever. For this reason, microorganisms do not propagate from the water accumulated in the bowl part 2, and it is possible to prevent germs from adhering to the staff during hand washing, thereby preventing infection from the staff to the user.
In addition, the hand-washing machine 1 has a compact structure that does not have a counter or the like that allows objects to be placed around the bowl as in the prior art, so the hand-washing machine 1 can be installed even in a narrow space in the facility. Therefore, the hand-washing device 1 dedicated to the staff can be installed separately from the wash-basin used by users such as hospital patients.

As mentioned above, although embodiment of the hand-washing machine by this invention was described, this invention is not limited to said embodiment, In the range which does not deviate from the meaning, it can change suitably.
For example, the shape of the bowl portion 2 may be a surface shape on the upper surface and no flat portion or concave portion (recessed portion) is formed, and its depth dimension, width dimension, bottom depth dimension, and outer peripheral upper edge 2b thickness dimension. The position of the drain hole 2c is not particularly limited and can be set as appropriate. And in this Embodiment, although the surface shape of the bottom face 2d of the bowl part 2 and the outer periphery upper edge part 2b is formed in the curved surface, it may be a shape which has a linearly inclined surface partially.
And the installation height with respect to the wall 5 of the bowl part 2 and the separation dimension between the bowl part 2 and the faucet metal fitting 3 can also be set suitably.

  Further, the size of the inclined surface or curved surface of the bottom surface 2d of the bowl portion 2 or the outer peripheral upper edge 2b is not particularly limited, but it is needless to say that an inclination angle that allows water to flow down is necessary. It is preferable that the water supplied from the faucet fitting 3 is inclined so as not to splash when hitting the bottom surface 2d.
