Description

  Aspects of the present invention generally relate to a net basket, and more particularly to a net basket provided in a kitchen sink.

  A net basket installed at the drain of the kitchen sink collects the trash contained in the water flowing through the sink without blocking the drainage. Examples of the garbage include vegetable skins and fine candy attached to tableware. When the waste contained in the water flows through the drain outlet, for example, the drain trap may be clogged, or the waste may flow into the river, resulting in water pollution. Therefore, a net basket is required at the drain of the kitchen sink.

  For example, there is a mesh basket manufactured using a metal such as stainless steel in order to suppress the occurrence of corrosion due to discharged water, detergent, or the like, or to suppress the occurrence of unevenness on the surface. In general, the antibacterial property of a metal net cage is higher than that of a resin net cage. For example, a metal material (punched metal) subjected to punching is used for a metal mesh cage or a metal strainer (Patent Document 1). If punching is used when forming water holes (holes through which water passes) of a metal net cage, water holes having a substantially uniform hole diameter can be formed. In addition, a net cage provided with water holes having a substantially uniform opening area can be formed relatively easily, and the manufacturing cost can be reduced.

  However, in such a metal net cage, if water flows relatively quickly through the side water holes provided around the bottom, dust may stay on the side. That is, the dust may not collect at the center of the bottom, but may stay scattered in substantially the entire side portion provided around the bottom. If the dust stays scattered on substantially the entire side, the dust may not fall even if the user repeatedly pulls the mesh basket when removing the dust inside the mesh basket. In this case, the user needs to scrape and remove the dust inside the mesh basket. Therefore, improvement of the removal property of the dust collected in the net cage or the cleanability of the net cage is desired.

JP 2010-126983 A

  The present invention has been made on the basis of recognition of such a problem, and is a metal net cage formed by a punching process that has high antibacterial properties and low manufacturing costs, and is capable of removing collected dust. It is an object of the present invention to provide a net basket that can be improved or can be cleaned.

  1st invention is the metal net cage | basket | basket installed in the part of the drain port provided in the sink of a kitchen, Comprising: The edge part contact | abutted to the part of the said drain port, and a some water flow hole A receiving portion that extends downward from the edge portion and has an inclined portion that is inclined toward the lower end portion provided at the lower end, and each opening area of the plurality of water holes is, A net basket which is substantially uniform and collects dust at the lower end by guiding the water from the inclined portion to the lower end when water containing dust flows into the receiving portion. .

  According to this mesh cage, it is possible to prevent dust from being scattered and staying in substantially the entire receiving portion. The dust collected at the lower end of the receiving part adheres to each other due to the viscosity of water and forms an aggregate. Garbage aggregates are heavier than garbage that does not form aggregates. Therefore, the user can remove the dust inside the mesh basket by repeating the mesh basket. Thereby, the net cage | basket can improve the removability of the collected garbage. Or a net basket can improve cleaning nature.

  A second invention is the net cage according to the first invention, wherein the total opening ratio of the receiving portion by the water passage hole is 1% or more and 40% or less.

  According to this mesh cage, the total aperture ratio of the receiving portion is relatively low. For this reason, the performance (water permeability) of water flowing into the net cage through the water passage hole is relatively low. For this reason, the water containing dust and flowing into the receiving part is difficult to pass through the water passage hole. As a result, the net cage can collect the dust at the lower end portion of the receiving portion without scattering the dust in the receiving portion.

  The dust collected at the lower end of the receiving part adheres to each other due to the viscosity of water and forms an aggregate. Garbage aggregates are heavier than garbage that does not form aggregates. Therefore, the user can remove the dust inside the mesh basket by repeating the mesh basket. Thereby, the net cage | basket can improve the removability of the collected garbage. Or a net basket can improve cleaning nature.

  According to an aspect of the present invention, a metal net cage formed by punching with high antibacterial properties and low manufacturing cost, which can improve the removability of collected dust, or cleaning properties. A mesh basket that can improve the performance is provided.

FIG. 1A and FIG. 2A are schematic perspective views showing a state in which the lid member 231 is provided on the net cage 100. FIG. 1B and FIG. 2B are schematic perspective views showing a state where the lid member 231 is removed.

  A sink 210 of the kitchen shown in FIGS. 1A and 1B is provided with a water discharge unit 220, a lid member 231, and a net basket 100. As shown in FIG. 1B and FIG. 2B, the sink 210 has a drain outlet 233. For example, the drainage port 233 is provided at the back side of one corner. In the sink 210 shown in FIGS. 1A and 1B, the drainage port 233 is provided at a corner portion between the right side surface 211 of the sink 210 and the rear side surface 213 of the sink 210.

  The water discharger 220 includes a first spout 221 and a second spout 222. However, the water discharger 220 does not necessarily have the first spout 221 and the second spout 222, and may have one or more spouts. The water discharger 220 discharges water toward the sink 210.

  The bottom surface 215 of the sink 210 has a substantially flat shape and is inclined toward the drain port 233. As indicated by arrows A1 to A6 shown in FIGS. 1A and 1B, the water discharged from the water discharger 220 flows along the slope of the bottom surface 215 of the sink 210 and travels toward the drain outlet 233.

  As shown in FIG. 2B, the net cage 100 according to the present embodiment is installed at the drain port 233. As shown in FIG. 2A, the lid member 231 is provided on the mesh basket 100. The net cage 100 is manufactured using, for example, a metal such as stainless steel, and collects dust contained in the water flowing through the sink 210. Examples of the garbage include vegetable skins and fine candy attached to tableware.

FIG. 3 is a schematic perspective view showing a net cage according to the present embodiment.
FIG. 4 is a schematic plan view showing a net cage according to the present embodiment.
FIG. 5 is a schematic cross-sectional view taken along a cutting plane AA shown in FIG.
6 is a schematic cross-sectional view taken along a cutting plane BB shown in FIG.

  As shown in FIGS. 3 and 4, the net cage 100 according to the present embodiment includes an edge portion 110 and a receiving portion 120. The edge portion 110 is provided at the upper end portion of the mesh basket 100, and abuts against a portion around the drain port 233 in a state where the mesh cage 100 is installed at the drain port 233. The receiving part 120 extends downward from the edge part 110 and collects dust contained in the water flowing through the sink 210.

  As shown in FIGS. 5 and 6, the receiving portion 120 has an inclined portion 125. The inclined portion 125 is inclined toward the lower end portion 123. The lower end portion 123 is provided at the lower end of the receiving portion 120 or the lower end of the mesh basket 100. In the example of the mesh basket 100 shown in FIGS. 3 to 6, the receiving part 120 has a side part 130 and a bottom part 140. The side portion 130 extends downward from the edge portion 110. The bottom portion 140 is connected to the side portion 130 and is surrounded by the side portion 130. The bottom portion 140 forms the bottom surface of the net cage 100 and is inclined toward the lower end portion 123 of the receiving portion 120.

  As shown in FIGS. 5 and 6, the side portion 130 and the bottom portion 140 are inclined downward. In this case, the inclined portion 125 exists over the side portion 130 and the bottom portion 140. On the other hand, the side portion 130 may extend in the vertical direction (vertical direction) in a state where the net cage 100 is installed at the drain port 233. In this case, the inclined portion 125 does not exist on the side portion 130 but exists on the bottom portion 140.

  Note that the boundary between the side portion 130 and the bottom portion 140 is not necessarily clear. That is, the receiving part 120 does not necessarily have to include the side part 130 and the bottom part 140. For example, the receiving part 120 may have a structure in which the bottom part 140 is directly connected to the edge part 110.

The receiving part 120 has a water passage hole 121 (see FIGS. 7A to 7C). The water passage hole 121 allows the water flowing inside the mesh basket 100 to pass outside the mesh basket 100. That is, the water passage hole 121 allows water that has entered the inside of the flow cage 100 to flow through the sink 210 toward the drain outlet 233.
Here, the water passage hole 121 provided in the receiving portion 120 will be further described with reference to the drawings.

FIG. 7 is a schematic plan view illustrating a specific example of the water passage hole of the present embodiment.
Fig.7 (a)-FIG.7 (c) are the typical enlarged views which expanded the surface of the receiving part 120 of this embodiment.

  As shown in FIG. 7A to FIG. 7C, the receiving part 120 has a water passage hole 121. In the specific examples shown in FIGS. 7A to 7C, the shape of the water passage hole 121 is a circle. However, the shape of the water passage hole 121 is not limited to a circle, and may be, for example, a hexagon or a rectangle.

  The water passage hole 121 is formed by punching. That is, a metal material (punched metal) that has been punched is used for the net cage 100 according to the present embodiment. Therefore, the diameters of the plurality of water passage holes 121 are substantially uniform. In other words, when punching is performed, the opening areas of the plurality of water passage holes 121 are substantially uniform. In the specification of the present application, “substantially uniform diameter” means, for example, an error within 10%, and “substantially uniform opening area” means, for example, an error within 25%.

  When press working for forming the net cage 100 is performed, the shape of at least one of the plurality of water passage holes 121 may be deformed. For example, the shape of the water passage hole 121 that is circular when the punching process is performed may be deformed to a shape different from the circular shape such as an ellipse. Even in this case, the opening areas of the plurality of water passage holes 121 are substantially uniform.

  The arrangement of the water passage holes 121 in the specific example shown in FIGS. 7A and 7B is called, for example, “staggered”. The arrangement of the water passage holes 121 in the specific example shown in FIG. 7A is called, for example, “60 ° staggered”. The arrangement of the water passage holes 121 in the specific example shown in FIG. 7B is called, for example, “45 ° staggered”. The arrangement of the water passage holes 121 in the specific example shown in FIG. 7C is called “parallel” or the like. In addition, the arrangement | sequence of the water flow hole 121 of this embodiment is not limited to the specific example represented to Fig.7 (a)-FIG.7 (c).

Next, returning to FIGS. 3 to 6, the mesh basket 100 according to the present embodiment will be described.
When water containing dust flows through the receiving portion, if the water flows relatively quickly through the water holes of at least one of the side and bottom inclined surfaces instead of the lower end portion of the receiving portion, the dust and the side portions and It may stay on the bottom inclined surface. In other words, the dust may not collect at the lower end of the receiving part, and may stay in a scattered state, for example, on substantially the entire side part. If the dust stays scattered on almost the entire side, even if the user repeatedly pulls the net cage when removing the dust inside the net cage, the dust (for example, small weight) will remain in the viscosity of the water. It may stick to the mesh basket and not fall. In this case, the user needs to scrape and remove the dust inside the mesh basket.

  On the other hand, in the net basket 100 according to the present embodiment, when water containing dust flows into the receiving portion 120, the lower end portion 123 of the receiving portion 120 is guided by guiding the water from the inclined portion 125 to the lower end portion 123. Collect trash. In other words, the net cage 100 according to the present embodiment collects dust near the lower end 123 and the lower end 123 of the receiving part 120.

  According to this, it is possible to suppress the dust from being scattered and staying on substantially the whole of at least one of the side portion 130 and the bottom portion 140. The dust collected at the lower end 123 of the receiving part 120 adheres to each other due to the viscosity of water and forms an aggregate. Garbage aggregates are heavier than garbage that does not form aggregates. Therefore, the user can remove the dust inside the mesh basket 100 by repeating the mesh basket 100. Thereby, the net basket 100 concerning this embodiment can improve the removability of the collected garbage. Moreover, the net basket 100 concerning this embodiment can improve cleaning property.

Next, the total aperture ratio of the receiving portion will be described with reference to the drawings.
FIG. 8 is a photograph illustrating an example of the result of the study conducted by the present inventor.
FIG. 8A is a photograph illustrating an example of a result of examination using the net cage 100 according to the present embodiment. FIG. 8B is a photograph illustrating an example of the result of the examination using the net cage according to the comparative example.

The inventor examined the total opening ratio of the receiving portion 120.
Here, the “total opening ratio” in this specification refers to the ratio of the area of all the water passage holes 121 to the area of the receiving portion 120 in a state where the water passage holes 121 are not provided.
The total aperture ratio of the receiving portion 120 of the mesh basket 100 according to the present embodiment shown in FIG. 8A is 40 percent (%). The total opening ratio of the receiving portion 120a of the mesh basket 100a according to the comparative example shown in FIG. 8B is 50%.

  As described above with reference to FIGS. 1 (a) to 2 (b), the present inventor has installed the net cages 100 and 100 a at the drain outlet 233 of the sink 210. Subsequently, the flow rate of water was set to 7 liters (L) / min, and tea leaves were poured with water. Thus, in this examination, tea leaves were used as the garbage of this embodiment. An example of the state of the tea leaves collected in the net baskets 100, 100a is as shown in FIG. 8 (a) and FIG. 8 (b).

  As shown in FIG. 8 (b), when the net cage 100a according to the comparative example is installed at the drain outlet 233, dust is collected at the lower end of the receiving portion 120a (see FIGS. 5 and 6). They do not collect and stay in a scattered state on the side part 130a and the bottom part 140a. This is presumably because the total opening ratio of the receiving portion 120a is 50%, so that water has flowed down relatively quickly through the water passage holes of the side portions 130a and the bottom portion 140a.

  On the other hand, as shown in FIG. 8A, when the net cage 100 over the drain port 233 is installed, the dust is collected without being scattered at the lower end 123 of the receiving portion 120. . In other words, dust is gathered near the lower end 123 and the lower end 123 of the receiving part 120.

  The total opening ratio of the receiving part 120 of this embodiment is lower than the total opening ratio of the receiving part 120a of the comparative example. Therefore, compared with the net cage 100a according to the comparative example, the performance (water permeability) of water flowing into the net cage 100 through the water passage hole 121 is lowered. Therefore, compared with the mesh basket 100a according to the comparative example, the water that contains tea leaves and flows into the receiving portion 120 is difficult to pass through the water passage hole 121. Thereby, the net basket 100 according to the present embodiment can collect tea leaves at the lower end 123 of the receiving part 120 without scattering the tea leaves on at least one of the side part 130 and the bottom part 140.

  While the total opening ratio of the receiving part 120 of this embodiment is lower than the total opening ratio of the receiving part 120a of the comparative example, the net basket 100 according to this embodiment suppresses the prevention of water discharge. It is preferable that the total aperture ratio of the receiving part 120 of this embodiment is 1 percent (%) or more and 40% or less. As described above with reference to FIG. 8A, the total opening ratio of the receiving portion 120 is preferably 40% or less. That the total opening ratio of the receiving part 120 is preferably 1% or more is based on the better living standard (BL standard). That is, according to the BL standard, it is required that 20 liters of water stored in the sink 210 can be discharged from the drain outlet 233 in one minute. Based on this, the total aperture ratio of the receiving part 120 is preferably 1% or more.

  According to this, the dust collected at the lower end 123 of the receiving part 120 adheres to each other due to the viscosity of the water and forms an aggregate. Garbage aggregates are heavier than garbage that does not form aggregates. Therefore, the user can remove the dust inside the mesh basket 100 by repeating the mesh basket 100. Thereby, the net basket 100 concerning this embodiment can improve the removability of the collected garbage. Moreover, the net basket 100 concerning this embodiment can improve cleaning property.
