As disclosed in Japanese Patent No. 116847 or the like, a storage unit is provided above the rear area of the countertop surface, or as a type B, a Japanese Utility Model Application Laid-Open No. 62-1.
No. 13741, Japanese Utility Model Application Laid-Open No. 63-127445,
As disclosed in Japanese Utility Model Unexamined Publication No. 2-62960, Japanese Unexamined Patent Application Publication No. 6-70824, and the like, a storage unit is provided above a rear edge of a countertop.

Further, if a special shape is given, type C
Japanese Utility Model Application Laid-Open No. Sho 62-109636,
As disclosed in JP-A-5-168534, a storage unit and a countertop located above the countertop are integrally formed as disclosed in JP-A-116848 and the like, or as a type D as disclosed in JP-A-5-168534. An L-shaped inclined plate that covers an installation wall erected behind the edge of the countertop and an upper surface of a work table arranged to protrude forward with respect to the installation wall is arranged, In some cases, the workbench-side end of the inclined plate reaches the outer edge of the sink in front of the workbench.

[0004]

As described above, there are types A, B, C, and D of the storage units of the sink, and each of them has the following problems. First, in the case of type A, a storage unit is provided on the countertop surface, which is a place exposed to severe conditions from the viewpoint of water resistance, so it is indispensable around the sink.
It can be said that the problem of the so-called water closing has not been considered at all.

[0005] That is, the most basic action using a sink is a cooking operation, and a washing operation is fundamentally indispensable for the cooking operation. Therefore, the area around the countertop is always a place where water is splashed. I have. And since the place is a place where the user always has a strong desire to keep it clean, it is a place where washing and wiping is performed on a daily basis. Things were in the way, making it inconvenient for washing and wiping.

[0006] In addition, it is important to solve the problem of water resistance in the construction scene for installing the sink, and the sink side of the wall located on the back side of the part where the sink is to be installed is subjected to water resistance. In order to prevent good tiles or to prevent water from flowing to the back of the sink, a construction method of sealing a boundary between the countertop and the tiles with a caulking agent is employed. Therefore, the storage unit also needs to be sufficiently waterproofed, and there is a problem in simply arranging the storage unit on the countertop surface, ignoring the enforcement of the waterproofing around the sink. .

In the market for sinks, the depth of the countertop is set to, for example, 650 mm.
There are many sinks designed to be wider than the depth dimension of 600 mm described in 017, and sinks with a large depth are widely accepted. This indicates that the market is demanding that the depth of the sink countertop be wider than before.
Even if the storage space is provided by the storage unit, the provision of the countertop on the rear end of the countertop impairs the basic usability of the sink required at present.

Next, in the case of the type B in which the storage unit is provided above the rear edge of the countertop, similarly to the case of the type A, the enforcement of the waterproofing measures around the sink cannot be ignored. At the same time, since the storage unit is located behind the sink and the storage space is farther than in the type A, it is inconvenient to wash or wipe the storage space with water.

Next, in the case of the type C in which the storage unit located above the countertop and the countertop are integrally formed, a large form is taken in consideration of the water finish. The integration of the storage unit and the countertop causes problems such as deterioration of work at the time of assembling the sink, deterioration of transportation efficiency, and increase in manufacturing cost. Therefore, a sink is formed on a countertop using stainless steel, artificial marble, and melamine post foam, and
A height of 5 called the back guard along the trailing edge of the sink
It is not used for an inexpensive sink only having an upright wall of about 0 to 80 mm, but is only used for a high-grade sink using an extremely special, expensive and original countertop.

[0010] Next, L covering the installation wall surface and the upper surface of the worktable arranged to protrude forward with respect to the installation wall surface.
In the case of the type D in which a character-shaped inclined plate is arranged and the end of the inclined plate on the workbench side reaches the outer edge of the sink in front of the inclined plate, the water finish is taken into consideration. The structure is such that water drops in the storage space fall into the sink. However, modern sinks always have a tap around the sink, almost all of which is behind the sink,
Since it is mainly mounted on the wall behind the sink or on the horizontal part of the countertop just behind the sink, there has been a problem that the faucet cannot be installed fundamentally in a normal manner and in a normal position.

[0011] As described above, in the conventional sink storage unit, when installed at the rear of the countertop of the sink, it is suitable for the countertop of a general-purpose sink with good water handling and is generally inexpensive. None had the condition that it could be used and the countertop could be widely used, and the user had to use the sink while enduring any problems.

[0012]

In order to solve this problem, a storage unit for a sink according to the present invention comprises an upright plate portion and an upper plate portion and a lower plate portion arranged at both ends thereof in parallel with each other. Thereby, while forming a U-shaped cross-sectional shape with an opening in one direction, with the opening positioned toward the countertop side of the sink, and placed behind the rear edge of the sink, The upper surface of the lower plate portion is formed so as to be inclined downward toward the opening, and the free end of the lower plate portion is located above the rear edge of the countertop. is there.

According to the present invention, since the storage unit is disposed behind the rear edge of the sink, the faucet attached to the countertop surface can be used as before. In addition, since the upper surface of the lower plate portion is formed so as to be inclined downward toward the opening, the water treatment is improved, so that corrosion of the storage unit due to water and deterioration of hygiene can be prevented.

Also, since the free end of the lower plate is located above the rear edge of the countertop, it is generally mounted behind the countertop of an inexpensive general-purpose sink. At this time, by arranging the free end of the lower plate portion above the front end portion of the back guard, attachment can be easily performed.

[0015]
