The problem to be solved by the present invention is to provide a structure having a drainage groove that is compact and easy to handle.

A first invention is a structure having a groove for draining food containing water, the structure having a plate-like structure, and the plate-like structure having a corner of a predetermined groove width. A groove (square groove part) and a cylindrical groove (cylindrical groove part) having a groove diameter larger than the groove width of the square groove part are connected in a keyhole shape in a plan view, and the cylindrical groove part is formed of the plate-like structure. It is a structure in which a tapered surface is formed on the periphery of one surface. A second invention is the structure according to claim 1, wherein the structure is a cutting board, and the tapered surface is formed on a lower surface of the cutting board. Further, a third invention is a method for draining food using the structure of the first or second invention, wherein the opening of the draining net containing the food is used as a handle, and the cylinder on which the tapered surface is formed is used as a handle. a first step of passing the handle upward with the groove on the lower side; a second step of draining the handle by pulling it upward in the square groove; and after draining the water, The method of draining foodstuffs includes a third step of removing the draining net from the structure by sliding the draining net until at least a portion of the draining net reaches the cylindrical groove.

In the present invention, since the groove for draining water has a keyhole shape in plan view, it is expected that the groove for draining water will be compact. In addition, the present invention has a tapered surface on the periphery of one side of the cylindrical groove, and the groove diameter is larger than the other side, so that the draining net can be inserted before draining, and the draining net can be removed after draining. However, it is expected that the effect will become easier.

FIG. 3 is a cross-sectional image diagram of the structure. This is an example of a tapered surface. This is an example of a cutting board (lower surface side) provided with a groove for draining water. It is an image diagram of the insertion of the draining net. It is an image diagram of the squeezing work of the draining net. Cross-sectional images of the draining net and groove after draining (the left figure is the cross section of the rectangular groove, the right figure is the cross section of the cylindrical groove).

(Example 1)
The following are embodiments of the present invention.

In this embodiment, a 12 mm thick resin cutting board was used as the structure 1. However, the material of the structure 1 is not limited to resin, wood, metal, etc. The thickness of the structure 1 is also not limited. When draining water in front of or behind a kitchen sink, as in Patent Document 1, the thickness of the cutting board is preferably 10 mm or more.

In the present invention, the draining groove (hereinafter referred to as "draining groove 2") is used to squeeze and drain a draining net (hereinafter referred to as "draining net 3") that contains foodstuffs, etc. It is a mechanism.

In the present invention, foodstuffs refer to foodstuffs before or during cooking, and foodstuffs that are no longer needed after cooking. Ingredients also include things that are produced during the cooking process, such as vegetable and fruit peels, tea leaves, and egg shells, even if they are not edible themselves.

FIG. 1 is a cross-sectional image diagram of a structure 1 having a drainage groove 2. As shown in FIG. The structure 1 in which the drain groove 2 is provided has a predetermined thickness, and at least the portion where the drain groove 2 is installed is required to have a plate-like structure.

However, in the present invention, a plate-like structure means having a region thick enough to allow the drainage groove 2 to be drilled therein, and does not necessarily have to be a flat plate structure. For example, the structure may have a curved surface like a pot lid.

The structure of the drainage groove 2 formed in the structure 1 is such that a square groove with a predetermined groove width (square groove part 2A) and a cylindrical groove with a groove diameter larger than the groove width of the square groove part 2A (cylindrical groove part 2B) are integrated. , and has a keyhole shape in plan view. Here, the keyhole shape is formed by connecting one end of the rectangular groove surface of the square groove section 2A in the longitudinal direction so that the two vertices of the rectangular groove surface are located on the periphery of the circular groove surface of the cylindrical groove section 2B. It is one continuous shape.

The groove width of the square groove portion 2A means the width of the groove in the transverse direction, and the groove diameter of the cylindrical groove 2B means the diameter when the groove is circular. In this example, the groove width of the square groove portion 2A is 5 mm, and the groove diameter of the cylindrical groove 2B is 10 mm. Further, the length of the groove in the longitudinal direction of the square groove portion 2A is 255 mm. However, these lengths are not limited.

A tapered surface 2b is formed at the periphery of one surface of the structure 1 in the cylindrical groove portion 2B. As a result, the groove diameter of the surface on which the tapered surface 2b is formed is larger than that of the other surface. In this example, the groove diameter on the tapered surface side is 17 mm, and the depth of the tapered surface is 6 mm. In the present invention, the tapered surface is defined as a sloped surface that forms an obtuse angle with respect to the plate-like surface, and even a surface that is processed to have a straight line when viewed in vertical cross section of the structure 1 has a convex surface. The surface may be curved into a shape or a concave shape.

The tapered surface 2b formed on the periphery only needs to be formed on a part of the periphery, and may include portions with different inclination angles and surface shapes. For example, it may be a surface processed so that the slope gradually becomes larger from the intersection of the square groove portion 2A and the cylindrical groove portion 2B (FIG. 2).

FIG. 3 shows an example in which draining grooves 2 are formed on the lower surface of the cutting board. A draining groove 2 is formed along one longitudinal side of a 280 mm x 480 mm cutting board. The location where the draining groove 2 is formed is not limited, but if the structure 1 is a cutting board, it is desirable to have a location where it does not interfere with work with a knife and where cut food materials are unlikely to fall.

Draining of the food is carried out by putting the food in the draining net 3 and squeezing it by applying pressure to the draining net 3 using the draining groove 2 of the cutting board. Ingredients include rice, chopped carrots, radish, vegetables such as cabbage, tea leaves, coffee grounds, egg shells, and anything else that comes from materials used in cooking. 4 and 5 show a part of the draining procedure.

The draining net 3 has a mesh-like surface and can separate water from the contents. The material of the bag is generally made of resin such as polyethylene or polypropylene, but is not limited to this, and may be made of any material such as metal, nonwoven fabric, or other natural materials. The size of the mesh is also not limited.

The draining work is as follows.
First, the upper part of the draining net 3 containing the food is inserted from the cylindrical groove 2B (the side on which the tapered surface 2b is formed). FIG. 4 shows the state after the draining net 3 has been inserted. In this way, the cylindrical groove portion 2B becomes a part used for inserting the draining net 3. Then, the part passed through to the upper surface of the cutting board becomes the handle part of the colander net 3. At this stage, the handle portion of the colander net 3 only needs to be secured on the upper surface side of the cutting board, and does not need to be pulled up to the portion containing the ingredients.

Next, the draining net 3 is slid into a predetermined position in the square groove portion 2A using the handle. The square groove portion 2A is a part used for draining water. As shown in FIG. 5, it is narrowed in the square groove portion 2A. The food is squeezed near the groove surfaces of the square grooves 2A on the lower surface of the cutting board, and water is separated from the mesh.

Although not shown, after the water is separated, the draining net 3 is slid by the handle into the cylindrical groove portion 2B. The cylindrical groove portion 2B is a part used for removing the draining net 3. The draining net 3 that has been slid to the cylindrical groove portion 2B is removed from the lower surface of the cutting board, and the draining operation is completed.
As described above, these series of operations may be performed by a device that realizes manual operations, and it does not matter whether they are performed manually or automatically.

Hereinafter, the findings obtained through repeated evaluation of the draining work according to the present invention will be explained.
It was confirmed that the shape according to the present invention is excellent as the shape of the food draining groove 2 applied to existing utensils such as cutting boards. This is because the draining groove 2 can be made more compact and the draining net 3 can be easily attached and removed from the draining groove 2.

Further, when the drain groove 2 is provided in an existing appliance, the groove shape is required to be compact and unobtrusive so as not to impede the original function of the appliance.

First, knowledge obtained regarding facilitation of attachment and detachment of the draining net 3 from the draining groove 2 will be explained.
A problem when a cutting board is provided with a square groove or a cylindrical groove independently is that it is difficult to attach the draining net 3 before draining, and it is difficult to remove the draining net 3 after draining.

For example, when the penetration direction of the groove is perpendicular to the plate-like surface, when installing the draining net 3, the draining net 3 is likely to get caught on the edge of the groove regardless of the size of the groove. That is, the draining net 3 does not smoothly transition to the state shown in FIG. 4, and may be damaged in some cases.

Further, if the groove is small, it becomes difficult to pass the draining net 3 through the groove. Furthermore, even if the draining net 3 passes through the groove, during the squeezing operation, the pressure applied to the food contained in the draining net 3 is concentrated near the groove, making it difficult to separate water from the entire food. This is more affected as the stretchability of the material of the draining net 3 increases.

Further, after draining, the draining net 3 gets stuck in the groove with the food during the squeezing operation, making it difficult to remove the draining net 3. Further, if the squeezing operation is performed with excessive force and a portion of the food moves to the upper surface of the cutting board, it may become more difficult to remove the colander net 3.

These problems are solved by the groove shape according to the present invention.
The draining groove 2 according to the present invention has a groove shape that becomes a keyhole shape in plan view by connecting a square groove and a cylindrical groove, and the cylindrical groove portion 2B becomes a part for attaching and detaching the draining net 3 to the structure 1, The square groove portion 2A becomes a part for squeezing the draining net 3. Further, the cylindrical groove portion 2B has a tapered surface 2b formed at the groove periphery on the insertion side when the draining net 3 is attached to the structure 1.

The tapered surface 2b forms an obtuse angle with the plate-like surface in a top and bottom cross-sectional view of the cutting board. Thereby, when the draining net 3 is inserted into the structure 1, the tapered surface 2b plays a guiding role and also prevents the draining net 3 from getting caught on the edge of the groove.

The square groove portion 2A has a predetermined length for draining water. As a result, in the squeezing operation of the draining net 3, as shown in FIG. 5, the pressure applied to the food material is prevented from concentrating at a predetermined location, and water is efficiently separated from the draining net 3.

The tapered surface 2b serves to facilitate the removal of the draining net 3 from the cutting board. FIG. 6 is a cross-sectional image of the draining net 3 and grooves after draining. The left diagram in FIG. 6 shows a cross section immediately after draining in the square groove portion 2A. Since the contents of the draining net 3 become dense in the square groove 2A, the draining net 3 becomes clogged in the square groove 2A. This also applies to the case of only cylindrical grooves.

In order to release the draining net 3 from being stuck in the square groove 2A, the draining net 3 is slid by the handle into the cylindrical groove 2B. The right diagram in FIG. 6 shows a cross section of the portion slid from the square groove portion 2A to the cylindrical groove portion 2B.

Here, regarding the cylindrical groove portion 2B, the groove area from the top surface of the cutting board to this side of the tapered surface 2b is defined as an X zone, and the groove area where the tapered surface 2b is formed is defined as a Y zone. When the draining net 3 is slid from the square groove portion 2A to the cylindrical groove portion 2B, the dense state of the food contained in the draining net 3 is alleviated. This is because the diameter of the cylindrical groove is larger than the width of the square groove.

Furthermore, the degree of density of the contents is as follows: X zone>Y zone. This is because the groove diameter of the Y zone becomes larger as it goes downward due to the tapered surface than that of the X zone. By sliding the draining net 3 into the cylindrical groove portion 2B having such two regions, the draining net 3 can easily come off downward. That is, the operator only has to move the handle of the draining net 3.

In this example, the draining effect was also evaluated when the food contained oil such as edible oil or beef tallow. It was confirmed that the groove structure according to the present invention is effective even when oil is contained.

Next, the knowledge obtained regarding the compactification of the drain groove 2 will be explained.
The cylindrical groove portion 2B according to the present invention not only facilitates insertion and removal of the draining net 3, but also contributes to making the groove more compact. For example, if the draining groove 2 is only the cylindrical groove part 2B, the groove diameter should not be at least several tens of mm level (for example, 20 to 30 mm) for a draining net containing several hundred grams of food. I can't drain the water properly.

On the other hand, the draining groove 2, which has a keyhole shape in plan view and is composed of the cylindrical groove part 2B and the square groove part 2A, allows the cylindrical groove to be made smaller in size. This is because the rectangular groove portion 2A acts as a restrictor for the draining net 3, and the cylindrical groove portion 2A has a groove diameter sufficient for attaching and detaching the draining net 3.

In this example, it was sufficient that the groove diameter of the cylindrical groove portion 2B was 10 mm. That is, when the draining net 3 is smaller in size than the present embodiment, draining is possible even if the groove diameter of the cylindrical groove portion 2B is even smaller, and it is also applicable to a smaller structure 1.

Further, in this embodiment, the length of the square groove portion 2A is set to be sufficient with respect to the groove diameter of the cylindrical groove portion 2B, but the square groove portion 2A may be shorter. The length of the square groove portion 2A should be set in relation to the size of the draining net 3, and the length necessary for the squeezing operation is sufficient. For example, the length of the square groove portion 2A may be approximately two to three times the diameter of the cylindrical groove portion 2B.

By making the draining groove 2 compact in this way, it becomes possible to install the draining groove 2 not only in the cutting board of this embodiment but also in various appliances without interfering with their original functions.

Since the draining groove according to the present invention is compact and easy to handle, it can be installed in various utensils such as cutting boards and used for draining water. In addition to cutting boards, it can be used with triangular corner lids. Furthermore, by applying it to a regular pot lid, it can also be used for cooking work.
