Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a water tank for a sink.
[0002]
[Prior art]
Conventionally, the following water tanks of this kind are known. That is, a part of the rear wall of the water tank of the sink is a protruding wall protruding rearward, a drainage device mounting opening is formed in the bottom wall portion of the water tank in front of the protruding wall, and the edge of the drainage device mounting opening A drainage device mounting edge that falls in a virtual horizontal plane is formed in the part, and a drainage device is attached to the drainage device mounting edge, and the lid is detachably mounted on the bottom wall in a form covering the drainage device upper part It is known that a drain is formed in this lid.
[0003]
[Disadvantages of the prior art]
The conventional water tank of the sink has the following drawbacks. That is, since the upper surface of the bottom wall around the drainage device is a series of continuous surfaces without any steps, when a part of the drainage that flows toward the drainage device collides with the protruding wall and flows backward, There is a drawback that fine garbage also gets around the drainage device on the drained water, sinks at that position and adheres to the bottom wall.
[0004]
[Means for eliminating the above-mentioned drawbacks]
The present invention employs the following means in order to eliminate the above disadvantages.
According to the first aspect of the present invention, a part of the rear wall of the water tank of the sink is a protruding wall protruding rearward, the bottom wall portion of the water tank in front of the protruding wall is a stepped portion, and a part is a stepped portion. A drainage device mounting opening is formed in the bottom wall so as to be located at the falling part, and a stepped drainage device mounting edge located in the virtual horizontal plane is formed at the edge of the drainage device mounting opening. A drainage device is mounted on the bottom wall so as to cover the drainage device, and the lid body has a rear surface whose top surface is flush or substantially flush with the top surface of the stepped portion. The upper surface has a front surface that is flush with or substantially flush with the bottom wall upper surface in front of the stepped portion, and a drain outlet is formed in the rear portion of the lid.
[0005]
[Effects of the Invention]
The invention of claim 1 has the following effects.
Because the fine garbage that flows along with the drainage to the stepped part of the bottom wall of the aquarium flows smoothly from the drainage part to the bottom wall other than the stepped part again, it reaches the garbage basket of the drainage device smoothly from the drainage port. Keep the aquarium clean. Further, the stepped portion is formed in the bottom wall portion of the water tank in front of the protruding wall, that is, the bottom wall excluding the stepped portion is a series of continuous surfaces including the front portion of the lid body, etc. Since the mounting surface is wide, it is easy to wash dishes and the like.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
In this description, the front means the lower side of FIG. 1, the rear means the upper side of the figure, the left means the left side of FIG. 1, and the right means the right side of the figure.
[0007]
A water tank 3 is provided on the top plate 2 of the sink 1. A part of the rear wall 4 of the water tank 3 is a protruding wall 5 protruding rearward, and a portion of the bottom wall 7 of the water tank 3 in front of the protruding wall 5 is a stepped portion 7b. With such a configuration, the bottom wall 7 has a bottom wall body 7a (a portion excluding the stepped portion 7b and a connecting portion described later), a stepped portion 7b, and a connecting portion that connects the two.
[0008]
The drainage device mounting opening 10 is located on the bottom wall 7 (a part of the bottom wall 7 includes the bottom wall main body 7a, the stepped portion 7b, and the connecting portion, and so on) so that a part thereof is positioned at the stepped portion 7b. A drainage device mounting edge 11 is formed at the edge of the drainage device mounting opening 10 and falls in a virtual horizontal plane. A known drainage device 13 is attached to the drainage device mounting edge 11 by known means. ing. The drainage device 13 includes a drainage device main body 14 having a trap mechanism (not shown) and a garbage basket 15 that is detachably fitted to the drainage device main body 14.
[0009]
A lid 17 made of synthetic resin or metal is detachably mounted on the bottom wall 7 so as to cover the drainage device 13. More specifically, a gap into which the lid body 17 is fitted is formed between the upper surface of the drainage device main body 14 and the upper surface of the bottom wall 7, and the lid body 17 is detachably fitted into this gap. .
The lid 17 has a rear portion 17b whose top surface is flush with or substantially flush with the top surface of the stepped portion 7b, and whose top surface is flush with or almost flush with the top surface of the bottom wall body 7a in front of the stepped portion 7b. A front portion 17a and a connecting portion connecting the two. That is, the front portion 17a of the lid body 17 is a series of continuous surfaces with the bottom wall body 7a, and constitutes a placement surface for tableware and the like.
A drain port 19 is formed in the rear portion 17 b of the lid body 17, and a drain guide wall 20 that is inclined downward toward the front is formed at the rear edge of the drain port 19.
[0010]
The distance L between the frontmost end (point A in FIG. 1) of the rear edge of the front portion 17a of the lid body 17 and the imaginary line connecting the left and right front ends (point B in FIG. 1) of the protruding wall 5 is 5 cm. It is as follows.
[0011]
[Modifications]
A description will be given below of modifications and the like.
(1) The boundary line between the bottom wall main body 7a and the stepped-down portion 7b has a convex curve toward the front as viewed from the plane in the embodiment. May be.
(2) The drainage guide wall 20 may or may not be present.
(3) “The lid 17 is detachably mounted on the bottom wall 7 so as to cover the drainage device 13” means that the lid 17 is placed on the upper portion of the drainage device 13, The case where it is mounted on the bottom wall 7 indirectly is also included.
[0012]
【The invention's effect】
The present invention has the following effects by the configuration as described above.
According to the first aspect of the present invention, the fine dust that has flowed along with the drainage into the stepped portion of the bottom wall of the aquarium smoothly flows from the drainage port without flowing back from the stepped portion to the bottom wall other than the stepped portion. Since it reaches the wastebasket of the drainage device, the aquarium can be kept clean. Further, the stepped portion is formed in the bottom wall portion of the water tank in front of the protruding wall, that is, the bottom wall excluding the stepped portion is a series of continuous surfaces including the front portion of the lid body, etc. Since the mounting surface is wide, it is easy to wash dishes and the like.
