BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wash basin, and more particularly to a wash basin suitable for a wash basin with a shower faucet capable of washing hair.

[0002]

2. Description of the Related Art As is well known, there are various types of wash bowls mounted on a vanity or the like, such as an elliptical, rectangular or triangular plan shape. Although most of them have been proposed, the present situation is that most of them have a front edge portion in the opening peripheral edge portion of the wash bowl body formed in a linear shape or a gentle arc shape.

By the way, in recent years, as shown in FIG.
In order to easily wash hair on the vanity, many vanities S having a shower faucet that can be pulled out have been proposed.

[0004] When washing hair on a vanity provided with such a shower faucet, a user generally wash the hair in a posture as shown in Fig. 5, and in this case, the head is washed. And the average movement of both arms (the hand, the midpoint between the hand and the elbow, and each of the three points on the elbow) are tracked with the video camera V (see FIG. 4)
It was found that each flow line when washing hair with the shower faucet accommodated traces the locus shown in FIG. 6, and each flow line when washing the hair with the shower faucet pulled out follows the locus shown in FIG. 7.

As is clear from FIGS. 6 and 7, the tendency of the flow line when washing the hair using the shower faucet is almost the same, except for the chin portion (shown by b in the figure). ,
The loci of the head and both arms are substantially inverted V-shaped. The difference between the two is the thickness and angle of the inverted V-shaped system. The inverted V shape is thicker when the shower faucet is pulled out and the hair is washed than when the hair is washed while the shower faucet is stored, and the locus of the tip of the head is the center of the wash bowl body 1. In contrast to this, it can be seen that when the hair is washed with the shower faucet stored, it feels more cramped.

[0006] When all of these factors are taken into consideration, it can be understood that washing the hair by pulling out the shower faucet makes it possible to wash the hair in a more natural posture.
Since it goes too far in the center of the washbasin, the elbow is likely to protrude outward from the washbasin body 1 (front edge of the countertop), and water drops flowing down along the arm when washing hair drip from the elbow to the floor and The problem of getting wet occurs. This tendency becomes particularly noticeable when a woman with long hair washes her hair because left-over washing occurs when the shower faucet is stored.

In consideration of the above, the working area of the head a and both arms when washing the hair with the shower faucet housed and when washing the hair by pulling out the shower faucet are as shown in FIG. Is illustrated in FIG.
In FIG. 9, reference numeral a is a head movement area, reference numeral b is a jaw movement area, reference numerals c and c are hand movement areas, reference numerals d and d are arm movement areas, and , Reference symbols e, e respectively indicate the elbow movement lines.

[0008] The present inventor has, a result of various studies of the work area distribution as a basis, in the vanity shower faucet is disposed, in order to prevent the falling of the washing water to the floor surface, wash It has been found that it is functionally optimal to form the planar shape of the bowl so as to cover at least the work areas indicated by the reference signs e and e.

The present invention was devised based on such knowledge, and the purpose thereof is to wash the wash basin with a shower faucet flowing down the floor along the elbow along the elbow. It is intended to provide a washbasin that is exceptionally easy to use and unique in design.

[0010]

In order to achieve the above-mentioned object, a washbasin according to the present invention has a washbasin in which both sides of the front edge of a washbasin are moved forward by an amount sufficient to cover the flow areas of both elbows when washing hair. A bulge is formed, and a central portion of the front edge sandwiched between both sides of the bulged front edge is gently curved inward so as to correspond to the body of the hair-washer. Is.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an embodiment shown in the accompanying drawings.

As shown in FIGS. 1 to 3, a washbasin bowl B according to this embodiment is a washbasin body 10 having an elliptical planar shape formed by enameling a pottery, a synthetic resin or a metal plate. And a drainage port 11 opened at the bottom of the wash bowl body 10 and a shallow water receiving recess 12 that is continuously provided outward from the opening peripheral edge portion 10a of the wash bowl body 10. There is.

Although not shown, the wash bowl B has various countertops (top plates) mounted on a known washstand.
By means known in the art, or integrally formed with the countertop. Further, for example, a known pop-up type drain plug is attached to the drain port 11. Of course, in addition to a general faucet, a shower faucet (not shown) that can be pulled out is arranged on the countertop of this vanity.

As described above, the water receiving recessed portions 12 are continuously provided so as to circulate outward from the opening peripheral edge portion 10a of the wash bowl body 10 and form a shallow water receiving portion. The receiving recess 12 makes it easy to place an elbow, and the water that has flowed down into the water receiving recess 12 does not flow in the direction of the countertop, and the wash bowl body 10 can be smoothly moved.
It is formed with a gentle slope so that it runs down to.

Further, on both sides of the front edge of the water receiving concave portion 12, bulging portions 15 and 15 projecting forward are formed, and the bulging portions 15 and 15 are used for washing hair by a shower faucet. In doing so, the wash water flowing along the elbow is received without flowing down to the floor surface and is made to flow to the wash bowl body 10. The amount of protrusion of the bulging portions 15, 15 is not particularly limited as long as it covers the range of e, e, which is the average flow area of the elbow, as shown in FIG. The protruding ends of the protruding portions 15 and 15 are
By forming the water receiving concave portion 12 sandwiched between 15 in front of the central portion of the front edge, the hair washing person can insert the body portion between the bulging portions 15 and 15 to wash the hair. Since the hair can be washed, the hair can be washed in a comfortable posture.
Of course, in this case, it is desirable that the center portion of the front edge between the bulging portions 15 and 15 has a gentle arc corresponding to the body portion.

As shown in FIG. 3, the wash-basin B constructed in this way has a head movement area a, a jaw movement area b, and hand movement areas c, c and arm movements. Since the line areas d, d are set within the wash-basin body 10 and the elbow movement lines e, e are set within the bulging portions 15, 15, for example, the elbow bulging portion When the hair is washed while being put on the 15, 15, the hair can be fixed because both arms can be smoothly washed, and moreover, all the water at the time of washing flows down to the wash bowl body 10, There is no risk of the floor getting wet.

According to experiments, the desirable dimensions of each part of the washbasin B which can obtain such an effect are as follows: the elliptical washbasin body 10 has a major axis of 600 mm, a minor axis of 380 mm and a water receiving recessed portion 12. Was 960 mm. Of course, these dimensions show a preferred example of the present invention, and the present invention is not limited to this, and the sink bowl body 10, the water receiving recess 12 and the bulge are not limited thereto. The shapes and dimensions of the parts 15 and 15 are not limited to those in the above embodiment, and the point is that similar effects can be obtained as long as they have a shape and dimensions that can cover the flow lines of the head and both arms during hair washing. Is obtained.

[0018]

As described above, the washbasin according to the present invention has both sides of the front edge portion of the washbasin at the central portion of the front edge portion.
Since it swells outward than when washing hair on a vanity with shower faucet, the washing water does not flow down the floor along the elbow, and the front edge of the wash bowl Since both sides are formed so as to bulge forward, they are unique in terms of design and have many excellent effects.
