Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sink used for washing dishes, fruits, vegetables, and the like at a school lunch site, for example.

[0002]

[Prior art]

 For example, kitchen equipment at school lunch sites requires sanitary and good workability. That is, in a cooking room, it is required that the floor is not wet, the cleaning is easy, and the work load on the worker is reduced. In order to meet this requirement, school lunch sites and the like, for example, a box-shaped tank body with an open top called a dry sink formed by bending and welding stainless steel sheet material and the upper end of the side wall of the tank body A sink having a rim frame connected continuously to the center is used.

FIG. 5 shows a cross-sectional shape of a conventional dry sink used at a school lunch site from a border frame to a tank body.

[0005] In FIG. 5, the rimping frame A includes a water return portion 53, which is continuously connected diagonally upward and inward from an upper end 52 of a side wall of a box-shaped tank main body B having an opening 51 at the top. A horizontal portion 55 horizontally connected to the outside through a bent portion 54 at the upper end of the portion 53; an inclined portion 56 continuously and obliquely provided upward from the end of the horizontal portion 55 to the outside; A hanging part 58 is formed by hanging downwardly through a bent part 57 at the upper end of the inclined part 56, and is horizontally directed toward the inner tank body side wall 60 through a bent part 59 at the lower end of the hanging part 58. And a horizontal portion 61 provided continuously with the horizontal axis. The horizontal portion 55 and the inclined portion 56 form the inner frame of the rimping frame A, and the hanging portion 58 including the bent portions 57 and 59 at both ends forms the outer frame of the rimming frame A. In addition, 62 is a water surface.

[0005]

[Problems to be solved by the invention]

 By the way, not only the bent portion 54 between the water return portion 53 and the horizontal portion 55 but also the bent portions 57 and 59 of the outer frame are formed in an acute angle, so that the manufacturing cost can be suppressed. For workers who need to contact the sharply-shaped part of the outer frame when washing or removing vegetables, etc. by hand, the physical burden of the work increases.

Although a water return portion 53 is provided to prevent water from splashing from the inside of the tank body B to the floor, the bent portion 54 has an acute angle, so that a vigorous hand washing operation is performed. In this case, return water and splashing water often adhere to the inner frame, and there is a problem that the cleaning time after the end of the hand-washing operation is prolonged.

[0007] Furthermore, in the horizontal portion 55 which is contaminated with return water or splashing water, draining cannot be performed sufficiently when taking out fruits, vegetables, etc., which have been washed by hand. In addition, draining cannot be performed in the inclined portion 56, and as a result, the floor cannot be drained. Will get wet.

Further, since the horizontal portion 61, which is the end of the edging frame A to be welded to the tank body side wall 60, is formed by simply bending a stainless steel sheet at the bent portion 59, the welding operation requires skill. Furthermore, welding cracks are likely to occur, and the rim A becomes weak in strength, causing a problem in durability. When a welding crack occurs, a gap M is generated as shown in FIG. 5, and there is a possibility that debris accumulates in the border frame A through the gap M, resulting in unsanitary conditions. The cleaning time is prolonged because it is difficult to remove.

In addition, since a drain port is provided at the center of the bottom of the tank body B, and the drain port is directly connected to the drain pipe, the cleaning work after finishing the hand washing and taking out of fruits, vegetables and the like. Occasionally, it was necessary to collect solid dirt such as vegetable waste by hand into a dirt collection / distribution net provided at the drainage outlet, take it out of the tank body B, and carry it to a refuse treatment plant.

In the cleaning operation, it is necessary to insert a brush into a drain pipe for cleaning, and the cleaning time becomes longer and is not sanitary.

The present invention has been made in consideration of the above points, and an object of the present invention is to reduce a physical burden on an operator who has to bring the body into contact with the border frame. In addition, it is possible to prevent the situation in which dirty water is transferred to the inner frame by hand-washing of fruits and vegetables and the cleaning time after the work is lengthened, and furthermore, the inner frame is taken out when hand-washed fruits and vegetables are taken out. To provide a sink that can drain water to a certain extent, avoid welding cracks at the edge of the edging frame, perform sanitary cleaning work, and easily collect and remove the garbage remaining in the tank body. It is in.
