  In a configuration in which the side edge in the longitudinal direction of the draining plate is placed on the upper surface flange of the sink, when the water discharged from the faucet flows down on the draining plate, the draining plate linearly extends in the short direction on the draining plate. The flowing water is easy to flow out on the top plate, increasing the labor of cleaning, and is not preferable for hygiene.

  Moreover, in the conventional trapezoidal draining plate, as shown in FIGS. 12 and 13 of Patent Document 2, there are relatively few portions to be placed on the upper surface flange of the sink, and the draining plate is placed on the upper surface flange of the sink. There was a problem that the stability of was not always good.

  Furthermore, the conventional draining plate is often placed below the top plate of the kitchen in a state of being placed on the upper surface flange of the sink. In such a configuration, for example, when a cutting board or the like is placed across the top board and the draining plate, there is a problem that the board is inclined.

  The present invention aims to solve the above-described conventional problems, and in particular, in a configuration in which the side edge in the longitudinal direction of the draining plate is placed on the upper surface flange of the sink and used, it is discharged from the faucet. It is an object of the present invention to realize a draining plate having a configuration in which water is unlikely to flow linearly in the short direction on the draining plate.

  In order to solve the above-mentioned problem, the present invention provides a draining plate for placing on the upper surface flange of a sink equipped with a faucet, and water discharged from the faucet onto the draining plate is in the short direction. Provided is a draining plate comprising plate portions in which drain holes are alternately arranged so that water cannot flow linearly.

  EMBODIMENT OF THE INVENTION The form for implementing the draining plate which concerns on this invention is demonstrated below with reference to drawings based on an Example.

  Fig.1 (a) is a figure which shows the sink which attaches the draining plate of this invention, FIG.1 (b) is a figure which shows the state which installed the draining plate 2 of this invention in this sink. The sink 1 includes a front wall 3, a rear wall 4, and left and right side walls 5 so as to surround the bottom surface, and is substantially rectangular in plan view when viewed from above.

  A horizontal upper surface flange 6 is formed along the upper edges of the front wall 3, the rear wall 4, and the left and right side walls 5 of the sink 1, and the upper surface flange 6 is a rising peripheral surface formed along the outer peripheral edge thereof. 7 is coupled to the upper surface of the top plate 8.

  The rear wall 4 of the sink 1 is configured as a front surface portion 9 having a central portion in the lateral width direction formed in a convex shape in a plan view, and left and right sides thereof as recessed portions 10 recessed rearward. The left and right recesses 10 are each surrounded by a side wall 5, a rear wall 11, and an inner wall 12 in plan view. A U-shaped fixing member 15 in a plan view is attached to the rear wall 11 of the recess 10.

  As shown in FIGS. 1B and 2A to 2C, the draining plate 2 of the present invention includes a substantially rectangular peripheral frame portion 21 for mounting on the upper surface flange 6 of the sink 1, and a plurality of the peripheral frame portions 21. And a plate portion 23 in which a water drain hole 22 is opened. As shown in FIG. 2B, the plate part 23 is placed and attached on the upper surface of the peripheral frame part 21. The plate part 23 is made of, for example, punching metal.

  In this draining plate 2, the plate portion 23 is not attached over the entire region surrounded by the peripheral frame portion 21, but the longitudinally front and rear ends are provided between the plate portion 23 and the peripheral frame portion 21. The opening portions 26 and 27 are provided in the respective portions so as to cover the entire region in the lateral direction.

  When the draining plate 2 is installed on the sink 1, the peripheral frame portion 21 is placed on the upper surface flange 6 of the sink 1. When the draining plate 2 is installed, the height of the peripheral frame portion 21 is set so that the upper surface of the plate portion 23 has the same height as the top plate 8 of the kitchen without any step as shown in FIG. ing.

  2D and 2E are views showing a first modification of the embodiment of the present invention, the draining plate 30 of the first modification is a part of the lower surface of the peripheral frame portion 21 ( A cushioning material 31 made of a rubber material, a resin, or the like is attached to the entire lower surface). When the draining plate 30 having such a configuration is placed on the upper surface flange 6, rattling of the draining plate 30 can be prevented.

  The plurality of drain holes 22 are formed over substantially the entire area of the plate portion 23 of the draining plate 2. FIG. 3 is a diagram for explaining the arrangement of the plurality of drain holes 22 opened in the plate portion 23 and the operation thereof.

  FIG. 6 is a view for explaining the arrangement of a plurality of drain holes 22 opened in the plate portion 36 of the draining plate 35 of the comparative example (conventional example) and the operation thereof. The arrangement of the drain holes 22 of the draining plate 2 of the present invention will be described below in comparison with the draining plate 35 of the comparative example.

  In the draining plate 35 of the comparative example (conventional example), as shown in FIG. 6A, a plurality of drain holes 22 are arranged and opened in the plate portion 36 in a matrix shape in plan view.

  Here, the plurality of drain holes 22 arranged in a matrix means that a plurality of vertical lines 38 extending in the longitudinal direction and a plurality of horizontal lines 39 extending in the short direction are drawn on the surface of the draining plate portion 36. If this is the case, the plurality of drain holes 22 are arranged and opened at the intersections of the vertical lines 38 and the horizontal lines 39.

To describe this configuration in another expression, in the draining plate 35 of the comparative example, the plurality of drain holes 22 have a constant opening pitch P _{L in} the longitudinal direction (intervals P in the longitudinal direction of the plurality of drain holes 22. column 41 of the drain hole comprising an opening in a row at _L) is, in the lateral direction at regular intervals D _S, and a plurality of rows arranged.

  And the column 41 of the drain hole which adjoins does not mutually shift | displace in a longitudinal direction, but is in the same position, and has the structure arranged as a matrix as a whole as shown to Fig.6 (a).

When this is seen in the lateral direction, a plurality of drain holes 22 are opened in one row at a constant opening pitch P _S (a mutual interval Ps between the plurality of drain holes 22 in the short direction). row 42 of drain holes 22 are a plurality of rows arranged at regular intervals D _L in the longitudinal direction. The adjacent rows 42 are located at the same position without being shifted in the lateral direction, and are arranged in a lattice as a whole as shown in FIG.

With respect to the draining plate 35 of such a comparative example, the plurality of drain holes 22 formed in the plate portion 23 of the draining plate 2 of the present invention are arranged as follows. As shown in FIG. 3 (a), column 45 of the drain hole 22 in which a plurality of drainage holes 22, which are opened in a row at a constant opening pitch P _L in the longitudinal direction, fixed in the lateral direction interval in D _S, and a plurality of rows arranged. The adjacent columns 45 are arranged in a staggered manner in the longitudinal direction.

Looking at this in transverse direction, the drain hole 22 in which a plurality of drainage holes 22, which are opened in a row at a in the lateral direction at a constant opening pitch P _S (at regular intervals P _S) row 46 has a plurality of rows formed at regular intervals D _L in the longitudinal direction. The adjacent rows 46 are alternately shifted in the lateral direction, and have a configuration as shown in FIG.

As described above, although the adjacent columns 45 are offset alternately in the longitudinal direction, the length of this displacement corresponds to the distance D _L of the longitudinal direction of each other of said plurality of rows 46. When viewed in the horizontal direction, adjacent rows 46 are staggered in the short direction, and the length of the shift corresponds to the distance Ds between the plurality of columns 45 in the short direction.

By the way, in the draining plate 2 of the present invention, as shown in FIG. 3A, the arrangement of the plurality of drain holes 22 that are alternately shifted in the plate portion 23 is arranged in the longitudinal direction of the row 46. The interval D _L may be set smaller than the interval D _s between the columns 45 in the short direction.

  With such a configuration, the water flowing in the short direction toward the edge 49 of the top plate 8 on the plate portion 23 of the draining plate 2 has a plurality of drain holes 22 in the flow path. Therefore, the possibility that the water is drained from the drain holes 22 is increased. Here, “the edge portion 49 of the top plate 8” is an edge portion of the top plate 8, and is a side edge on the side wall 5 side of the sink 1 (more precisely, a rising peripheral surface on the side wall 5 side of the sink 1. 7) Say the edge that touches.

Further, the longitudinal direction of the opening pitch P _L, as shown in FIG. 4 (a), may be configured to be smaller than the spouting diameter Wd faucet. With such a configuration, the water discharged from the faucet spans the two drain holes 22 at the water discharge position and in the flow path from the water discharge position toward the edge 49 of the top plate 8 in the short direction. Since there is a possibility, the amount of water discharged from the drain hole 22 to the sink 1 increases.

FIG.4 (b) shows the modification 2 of the draining plate of an Example. In the draining plate 50 according to the second modification, the opening pitch P _{L in} the longitudinal direction is closer to the outer side (closer to the edge 49 of the top plate 8) in the shorter direction than the opening pitch P _L1 closer to the center of the plate portion 23. Accordingly, it is set so as to become gradually smaller as P _L2 , P _L3 , and P _L4 .

  With such a configuration, as will be described in detail in the next section of action, the water flowing in the short direction toward the edge 49 of the top plate 8 on the plate portion 23 is the edge 49 of the top plate 8. Many of them can be effectively drained by the time they arrive.

(Function)
The operation of the draining plate 2 of the embodiment having the above configuration will be described. As shown in FIG. 1B, the draining plate 2 is installed with its longitudinal direction facing the front and rear of the sink 1. In the example shown in FIG. 1B, the draining plate 2 has the peripheral frame portion 21 mounted on the upper surface flange 6 so as to be positioned at the left-side recessed portion 10 in the horizontal width direction (left and right direction in the drawing) of the sink 1. Although installed and installed, it may be installed so as to be in the position of the left recess 10.

  Since the peripheral frame portion 21 of the draining plate 2 of the present invention is formed in a substantially rectangular shape, the area on which the peripheral frame portion 21 is placed on the upper surface flange 6 is increased, and the sink 1 is disposed before and after the peripheral frame portion 21. Since they are in contact with the front and rear rising peripheral surfaces 7, they are difficult to slide in the horizontal direction, are not easily displaced, and are not easily dropped.

  Therefore, the draining plate 2 can be more stably placed on the upper surface flange 6 of the sink 1 without providing extra parts such as a stud pin for locking the draining plate 2 around the sink 1. Can be installed in the sink 1.

  In the first modification as shown in FIGS. 2D and 2E, the cushioning material 31 made of a rubber material or a resin is attached to a part of the lower surface of the peripheral frame portion 21. When the draining plate 30 is placed on the flange, rattling can be prevented.

  Before and after the draining plate 2, the peripheral frame portion 21 is placed on the upper surface flange 6, but opens at the front and rear openings 26 and 27. When the draining plate 2 is removed from the sink 1, it is possible to take out the openings 26 and 27 by placing a hand.

  As will be described later, the storage rack 60 can be attached to and removed from the fixing member 15 of the recess 10 through the rear opening 27 with the draining plate 2 installed.

  Next, the action of the plurality of drain holes 22 formed in the plate portion 23 of the draining plate 2 of the present invention will be described in comparison with a comparative example. When the discharge port 53 of the faucet 52 is located above the draining plate 2, the water discharged from the faucet 52 flows down onto the draining plate 2. As shown in FIG. 3B, the water discharged from the faucet 52 flows from a position (referred to as “water discharge position”) 54 on the draining plate 2 that flows down to the periphery.

  In the draining plate 35 of the comparative example, as shown in FIG. 6 (b), the water discharged from the faucet 52 has two columns 41 and 41 of two drain holes 22 and two drains on the plate portion 36. It is assumed that water is discharged to a position between the rows 22 and 42 of the hole 22 (this position becomes the water discharge position 54). Then, on the plate part 36, water flows from the water discharge position 54 as follows.

  As shown in FIG. 6 (b), the water flowing in the longitudinal direction among the water flowing in the surroundings passes between the columns 41 and 41 of the drain holes 22 and flows on the draining plate 2 (see arrow 55). . Since the distance from the water discharge position 54 to the front wall 3 and the rear surface wall 11 of the sink 1 is long, the water that flows in the longitudinal direction toward the front and rear of the sink 1 tends to decrease in water.

  Of the water flowing in the surroundings, most of the water flowing in an oblique direction in plan view toward the edge portion 49 of the top plate 8 between the longitudinal direction and the short direction is mostly in the sink 1 from the drain hole 22. Flow down. Therefore, the amount of water flowing in an oblique direction toward the edge 49 of the top plate 8 decreases until it reaches the edge 49 of the top plate 8, and even if it reaches the edge 49 of the top plate 8. The momentum through which the water flows is reduced, and it flows with an inclination angle with respect to the edge portion 49 of the top plate 8, so that it is difficult to overflow on the top plate 8.

  However, the water flowing in the short direction among the water flowing in the surroundings passes between the rows 42 and 42 of the drain holes 22 and flows on the draining plate 2 (see arrow 56). In the short direction, since the distance from the water discharge position 54 to the edge portion 49 of the top plate 8 is short, the water traveling toward the edge portion 49 of the top plate 8 in the short direction does not decrease the momentum of the water relatively. Since it reaches the edge 49 of the top plate 8, water tends to overflow on the top plate 8. FIG. 6B shows the water 57 overflowing on the top plate. The above is the operation of the draining plate 35 of the comparative example.

  In contrast to such a comparative example, the plurality of drain holes 22 of the present invention are arranged shifted in the plate portion 23 of the draining plate 2 as shown in FIG. As shown in b), among the water flowing from the water discharge position 54 to the surroundings, the water flowing in the short direction toward the edge 49 of the top plate 8 has a relatively large number of drain holes 22 in the flow path. Therefore, the water easily flows down from the drain hole 22 into the sink 1 and is drained.

  A part of the water flowing in an oblique direction in plan view from the water discharge position 54 toward the edge 49 of the top plate 8 is drained into the sink 1 from the drain hole 22 and reaches the edge 49 of the top plate 8. The amount of water is reduced by the time it is done. Furthermore, even when the edge 49 of the top plate 8 is reached, the momentum of the water flowing in the flow path is reduced, and it flows with an inclination angle with respect to the edge 49 of the top plate 8. It becomes difficult to overflow on the top plate 8.

  In view of the above, the water traveling in the short direction toward the edge 49 of the top plate 8 is the edge of the top plate 8 even though the distance from the water discharge position 54 to the edge 49 of the top plate 8 is short. The amount of water decreases until reaching 49, and even if it reaches the edge portion 49 of the top plate 8, the momentum of flowing water is reduced, so that it is difficult for the top plate 8 to overflow. Therefore, the peripheral top plate 8 at the edge 49 of the top plate 8 is less likely to be contaminated with water discharged from the faucet 52.

Further, the longitudinal direction of the opening pitch P _L, as shown in FIG. 4 (a), when is set smaller than the spouting diameter W _D of faucet 52, the water discharged from the water faucet 52, the water discharge position 54, or in the flow path from the water discharge position 54 to the edge 49 of the top plate 8 in the short direction, the two drain holes 22 in the longitudinal direction are extended, so that the water is easily discharged from the drain hole 22 to the sink 1.

By the way, as shown in FIG.4 (b), the drain hole 22 of the modified example 2 is _PL1 ~ with the opening pitch of a longitudinal direction facing the outer side from the center side in the transversal direction of the plate part 23. The density is gradually reduced to P _L4 , that is, the density of the drain holes 22 is gradually increased. With such a configuration, the following actions (1) and (2) occur, and they act synergistically to more effectively prevent water from overflowing to the upper surface of the top plate 8. It becomes possible to suppress

(1) The water flowing in the short direction toward the edge 49 of the top plate 8 increases in density of the drain holes 22 as it approaches the edge 49 of the top plate 8, so that water that goes straight to the edge 49 is The remaining water travels at an angle of inclination with respect to the edge 49 and is further decelerated.

(2) When water flows toward the edge 49 of the top plate 8 from the center of the draining plate 2, the water is strong and the flow speed is high near the center, but it is relatively difficult to drain from the drain hole 22. When approaching the portion 49, the momentum of the water decreases, the flow velocity becomes slow, and the water tends to stay. By increasing the density of the drain holes 22, it becomes possible to more effectively and effectively drain the water that tends to be stagnated due to such a decrease in the flow velocity.

  Next, a mode in which the storage rack 60 is used with the draining plate 2 installed in the sink 1 in FIG. 5 will be described. As shown in FIG. 5C, the storage rack 60 is formed of a wire rod, and a U-shaped hooking portion 61 facing downward is formed at the rear portion and in the center in the horizontal width direction. The storage rack 60 can be attached to and removed from the rear wall 11 of the recess 10 of the sink 1.

  In order to attach the storage rack 60 to the rear wall of the recess 10 of the sink 1 with the draining plate 2 installed in the sink 1, the storage rack 60 is inserted into the sink 1 from the opening 27 at the rear of the draining plate 2. The U-shaped hook is hooked on the U-shaped fixing member 15 (see FIG. 1) and fixed to the rear wall 11 of the recess 10 as shown in FIGS. 5 (a) and 5 (b). To do. Conversely, the storage rack 60 can also be removed from the sink 1 with the draining plate 2 installed in the sink 1.

  As mentioned above, although the form for implementing the draining plate which concerns on this invention was demonstrated based on the Example, this invention is not limited to such an Example, The technical statement described in the claim It goes without saying that there are various embodiments within the scope of the matter.

  Since the draining plate according to the present invention is configured as described above, it is installed not only in the draining plate used by being attached to a kitchen sink, but also in an industrial sink used for cleaning industrial products, agricultural products, marine products, etc. It can also be used as a draining plate.
