Description

Face washing device

Technical Field

The present invention relates to a wash basin, and more particularly, to a wash basin having an overflow port.

Background

Conventionally, an overflow port is provided at an upper portion of a basin portion of a wash basin or the like in order to prevent overflow of accumulated water. The overflow port is connected to an overflow drain pipe disposed outside the bowl portion by, for example, a bent pipe. A drain port is provided on the bottom surface of the bowl portion, and an overflow drain pipe extending from the overflow port is connected to a drain pipe continuous with the drain port, thereby draining the wash basin (see, for example, patent document 1).

Since the drain pipe is attached to the outside of the wash basin, there is a demand for the drain pipe to be inconspicuous in appearance. Therefore, a technique has been proposed in which the bowl portion and the overflow drain pipe having a hollow structure are separately formed and are insert-molded together with a metal fitting for connecting the bowl portion and the overflow drain pipe (see, for example, patent document 2).

Detailed Description

Embodiments of the present invention are described below with reference to the drawings.

Fig. 1 is a front perspective view showing a wash basin 1 according to the present embodiment, and fig. 2 is a rear perspective view. Fig. 3 is a plan view of the wash basin 1. The wash basin 1 has a basin 2 and an overflow 3. As shown in fig. 1, the cleansing basin 1 of the present embodiment is a so-called half-tub type cleansing basin, which is installed on a bathroom stand 100 as a bathroom stand, and a part of the basin 2 is located above the bathroom stand 100 and a part of the outer surface of the basin 2 protrudes.

The bowl portion 2 is a container having a recess for storing water or receiving water discharged from a faucet (not shown). As shown in fig. 3, the bowl portion 2 has a substantially rectangular shape with rounded corners in plan view, and has a shallow dish-like shape gently curved from the upper side to the lower inner side in side view. The bowl portion 2 has a drain opening 21, a drain pipe connecting portion 24 (see fig. 2), an inner side surface portion 22, and an outer side surface portion 23.

Fig. 4 is a side view of the wash basin 1. As shown in fig. 4, the drain port 21 is a through hole formed in the bottom surface of the bowl portion 2 and located at the lowermost position of the bowl portion 2.

The drain pipe connecting portion 24 is a tubular portion extending downward from the drain opening 21. The drain pipe connecting portion 24 is a portion connecting the drain port 21 and the drain pipe 25.

The inner side surface 22 is a side surface inside the bowl 2 extending from the drain opening 21 toward the periphery of the upper end of the bowl 2.

The outer surface portion 23 is an outer surface extending downward from the upper end of the bowl portion 2. The outer surface portion 23 includes a 1 st outer surface portion 231 and a 2 nd outer surface portion 232. The 1 st outer side surface 231 is a band-shaped portion extending downward from the upper end of the bowl portion 2 by a predetermined length and along the periphery of the bowl portion 2. As shown in fig. 1 and 4, in the present embodiment, the 1 st outer side surface 231 is a portion protruding to the bathroom stand 100 in the installed state. The 2 nd outer side surface 232 is a curved surface extending from the lower end of the 1 st outer side surface 231 to the drain opening 21, and is disposed below the toilet and bathroom stand 100 in the installed state.

The overflow portion 3 is disposed at an upper portion of the distal end surface side of the bowl portion 2, and is a drainage structure at the upper portion of the bowl portion 2 that prevents hot water from overflowing and spilling from the bowl portion 2 when hot water is accumulated in the bowl portion 2. The overflow portion 3 includes an overflow port 31, an overflow drain pipe 32 constituting a part of the overflow drain passage, an overflow cover portion 33, and an overflow cover connecting portion 34.

The distal end surface of the tub portion 2 in this specification means a surface of the user facing the user with the tub portion 2 therebetween when the user stands in front of the cleansing basin 1.

Fig. 5 is a rear view of the wash basin 1. As shown in fig. 1 and 5, the overflow port 31 is a through hole formed at a position spaced downward from the upper end portion by a predetermined distance on the distal end surface side of the bowl portion 2. The overflow port 31 is a long hole that is long in the lateral direction along the longitudinal direction of the bowl portion 2.

The overflow cover portion 33 is a cover that covers the back side of the overflow port 31. The overflow cover portion 33 is integrally and continuously formed with the bowl portion 2. The overflow cover portion 33 protrudes from the distal end surface of the bowl portion 2 toward the depth side. The overflow cover portion 33 is formed at a substantially central portion in the longitudinal direction of the bowl portion 2 on the back side of the distal end surface of the bowl portion 2 so as to bulge out from the outer side surface portion 23 of the bowl portion 2. The overflow cover 33 has an overflow upper surface 331, a rib 332, and an overflow side surface 333.

As shown in fig. 4, the overflow upper surface portion 331 is formed to protrude in a direction away from the 1 st outer surface portion 231 of the bowl portion 2 as it goes downward from the upper end of the bowl portion 2. The overflow upper surface portion 331 is inclined downward in such a manner as to be less visible to a user of the wash basin when the user stands in front of the basin portion 2. The "downward inclination which is not easily visible to the user" means, for example, an inclination which is not easily visible to a user standing in front of the washbasin (the height h2 of the line of sight is 150cm to 170cm) when the height h1 of the upper end of the bowl portion 2 is set at a position of 800 mm to 850mm and the depth D of the bowl portion 2 is 300mm to 350mm (see fig. 7). The angle of inclination of the overflow upper surface 331 is, for example, 45 degrees or more, preferably 45 degrees or more and 70 degrees or less, with respect to the angle θ formed by the horizontal plane H and the overflow upper surface 331 along the horizontal plane H at the upper end of the bowl 2.

As shown in fig. 2 and 5, the overflow upper surface portion 331 is inclined so that its tip widens as it goes from the upper end to the lower end of the overflow upper surface portion 331 when viewed from the rear. The overflow upper surface 331 has a width larger than the overflow port 31 and surrounds the periphery of the overflow port 31 in the 1 st outer surface 231 of the bowl 2. The overflow upper portion 331 and the 1 st outer portion 231 are hollow.

The rib 332 is disposed at the lower end of the overflow upper surface 331, and extends and protrudes horizontally from the lower end of the overflow upper surface 331. As shown in fig. 5, the rib 332 is formed on an imaginary extension line of the lower end of the 1 st outer side surface 231 at a boundary between the 1 st outer side surface 231 and the 2 nd outer side surface 232 in the outer side surface 23 of the tub 2.

The relief side surface part 333 is disposed below the rib 332 and extends downward. As shown in fig. 4, the overflow side surface part 333 has a predetermined height from the rib 332 toward the lower side while bulging toward the depth side from the 2 nd outer side surface part 232. The overflow side surface part 333 is formed in a substantially rectangular shape in a rear view, and has a width from an upper end to a lower end of the overflow side surface part 333 that is larger than the overflow port 31 and extends with a constant width. The overflow side part 333 is hollow and forms a wide space for receiving water overflowing from the overflow port 31. The width of the overflow side surface part 333 is about 1/4-1/3 of the length of the tub part 2 in the longitudinal direction.

Fig. 6A is a plan view of the overflow cover connection portion 34, and fig. 6B is a side view. The overflow cover connecting portion 34 is a socket connecting the overflow cover portion 33 and the overflow drain pipe 32. The overflow cover connection 34 has an upper connection 341 and a lower connection 342. The overflow cover connection part 34 is connected to the lower end of the overflow side part 333 of the overflow cover part 33, and is not visible from the upper part of the sanitary ware stand 100.

As shown in fig. 5 and 6A, the upper connection portion 341 has a substantially rectangular shape whose cross section is smaller by one than the cross section of the overflow side surface portion 333 so as to be inserted into the lower end portion of the overflow side surface portion 333. The upper connection portion 341 has a convex portion 341a protruding along the periphery inside the periphery of the upper connection portion 341, and the convex portion 341a is fitted inside the lower end portion of the overflow side surface portion 333. As shown in fig. 6B, the upper connection portion 341 narrows as it goes downward.

The lower connection portion 342 is a tubular attachment opening continuous with the lower end of the upper connection portion 341 and is inserted into the overflow drain pipe 32.

One end of the overflow drain pipe 32 is connected to the overflow port 31 via the overflow cover portion 33, and the other end is connected to the drain pipe connection portion 24 of the bowl portion 2. The overflow drain pipe 32 forms a part of a drain path connected from the overflow port 31 to the drain pipe 25.

The overflow drain channel continues from the overflow port 31 to the overflow drain pipe 32 through the overflow cover portion 33 and the hollow portion in the overflow cover connection portion 34. The overflow drain path is connected to the drain connection portion 24 extending from the drain port 21 in the bottom surface of the bowl portion 2 via the overflow drain pipe 32, and merges with the drain path of the bowl portion 2.

The overflow drain passage is covered with an overflow cover portion 33 above the bowl portion 2. The overflow port 31 is formed in a substantially rectangular shape, and the overflow cover 33 forms a drainage channel so that the width from the overflow upper surface portion 331 to the lower end of the overflow side surface portion 333 is not greatly reduced, and therefore the drainage amount is large, and for example, 10 liters or more of water can be drained in one minute.

The wash bowl 1 having the bowl portion 2 and the overflow portion 3 is made of resin and is integrally formed by press molding. The overflow port 31 of the bowl portion 2 may be integrally formed so as to form a hole at the same time as the press forming, or may be formed so as to form a hole in the bowl portion 2 later.

Fig. 7 shows a use state of the wash basin 1 of the present embodiment.

The washing unit 1 is disposed in a so-called container type, in which the toilet and bathroom stand 100 is disposed below the rib 332 and the upper side of the washing unit 1 protrudes from the toilet and bathroom stand 100 beyond the rib 332. In other words, the rib 332 is placed on the sanitary ware base 100 to define the boundary between the wash basin 1 and the sanitary ware base 100.

More specifically, the rib 322 is disposed in a half-container shape, i.e., at a position higher than the drain port 21 disposed on the bottom surface of the bowl portion 2.

As shown in fig. 7, when a user stands in front of the wash basin 1, even if the wash basin 1 is disposed to protrude above the sanitary bath 100, the overflow cover portion 33 is inclined downward to be hardly visible to the user, and the drainage structure of the overflow portion 3 is inconspicuous.

The cleansing basin 1 according to the present embodiment has the following operational effects.

(1) The wash basin 1 includes: a basin part 2; a drain port 21 formed in the bottom surface of the bowl portion 2; an overflow port 31 formed in a distal end surface of the bowl portion 2; an overflow drain path having one end connected to the overflow port 31 and extending downward; and an overflow cover part 33 formed to protrude from the distal end surface of the bowl part 2 toward the depth side so as to cover the overflow drainage passage. The overflow cover portion 33 includes an overflow upper surface portion 331, and the overflow upper surface portion 331 is inclined downward so as to be less visible to a user when the user stands in front of the basin portion 2 of the wash basin 1.

Accordingly, since the overflow cover portion 33 covers the overflow drain passage that drains water from the overflow port 31 on the depth side of the overflow port 31, structural portions such as a pipe connection portion are not visually recognized, and the appearance is simplified and the appearance is improved. Further, since a mechanically fine structure such as a screw is not exposed, dust, garbage, and the like are not accumulated, and sanitation is achieved. Further, since the overflow cover portion 33 is inclined downward so as to be less visible when a user stands in front of the bowl portion 2, the overflow drain pipe 32 and the like are not visible even when the wash basin 1 is placed on the sanitary toilet 100, for example, and the appearance is improved.

(2) The overflow upper surface portion 331 is inclined at an angle of 45 degrees or more with respect to the horizontal plane. This makes it difficult to visually recognize the user when the user stands in front of the bowl 2. This can more reliably achieve the same effects as described above.

(3) The overflow cover 33 includes a rib 332 disposed at a lower end of the overflow upper surface 331 and extending and protruding horizontally from the lower end, and an overflow side surface 333 disposed below the rib 332 and extending downward. Thus, the rib 332 extends and protrudes in the horizontal direction, and therefore, the structure below the rib 332 is less likely to be visually recognized from the upper portion of the wash basin 1, and the appearance is improved. Further, the overflow side surface part 333 is formed to extend to the lower part of the rib 332, so that the flow path of the drainage channel covered by the overflow cover part 33 can be made thick.

(4) A container type wash basin is used in which the bath base 100 is disposed on the lower surface of the rib 332 and the upper side of the wash basin protrudes from the bath base 100 beyond the rib 332. Thus, the rib 332 makes the boundary between the wash basin 1 and the toilet and bathroom stand 100 clear, and the wash basin 1 is not easily dropped from the wash basin 1 installation hole provided in the toilet and bathroom stand 100 by placing the rib 332 on the toilet and bathroom stand, and the installation is easy.

(5) The rib 332 is located higher than the bottom surface of the tub 2. This can reduce the height of the rib 332 and increase the depth of the bowl 2. In this way, the half-tub type wash basin 1 in which the outer side surface portion of the tub portion 2 partially protrudes from the toilet and bathroom stand 100 also provides the same effects as described above.

(6) The overflow drain path is configured to discharge 10 liters or more of water in one minute. This ensures a sufficient amount of drainage, and therefore the possibility of water overflowing to the outside of the washing tub 1 or the like is reduced, and the function of the overflow portion 3 is improved. Further, since a sufficient amount of water can be ensured, for example, the basin 2 can be designed in a shallow dish shape, so that the appearance is improved and the number of places where the wash basin 1 can be installed is increased.

(7) The wash tub 1 is integrally formed by press molding. Thus, the bowl portion 2 and the overflow portion 3 can be integrally formed, and the overflow drain pipe 32 can be connected to the lower end portion of the overflow side surface portion 333 of the overflow cover portion 33 via the overflow cover connecting portion 34 and the like. This facilitates the installation of the overflow drain pipe 32. Further, since the connection and installation of the overflow drain pipe 32 can be performed below the overflow portion 3, the structural portion of the piping is not visible from the outside even in an arrangement in which the wash basin 1 is disposed above the toilet and bathroom stand 100.

The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments and can be modified as appropriate.

For example, in the above embodiment, the overflow port 31 and the overflow cover 33 are formed in a horizontally long shape along the longitudinal direction of the wash basin 1, but the present invention is not limited thereto. The shapes of the overflow port 31 and the overflow cover 33 can be changed as appropriate according to design, such as being circular.

In the above embodiment, the half-tub type wash basin 1 in which the basin 2 is provided so as to protrude above the toilet and bathroom stand 100 has been described, but the present invention is not limited thereto. The basin 2 may be a container whose bottom surface is positioned above the bathroom table, or a large part of the basin 2 may be stored below the bathroom table surface of the bathroom table.
