Description

  The present invention relates to a sink structure.

  An example of a conventional sink structure is shown in FIG. 8, in which 1 is a frame body, 2 is a rectangular deep-drawn container-shaped sink installed on the frame body 1, and 3 is provided on the bottom surface 2a of the sink 2. The drainage port 4 is a water-sealed deodorizing drainage trap installed on the lower surface of the sink 2 so as to be positioned below the drainage port 3 to prevent odors from leaking into the sink 2. The deodorant drain trap 4 includes a bottomed cylindrical container 4a fixed to the bottom surface 2a of the sink 2, a cylindrical deodorant cap 4b housed in the cylindrical container 4a and fixed in a ceiling, The upper end is located in the deodorizing cap 4b and includes a drain pipe 4c that penetrates the bottom surface of the cylindrical container 4a and extends downward. A drain pipe 5 is connected to the lower end of the drain pipe 4c.

  One end of an overflow pipe 7 is connected to the overflow port 6 formed on the front wall surface 2b of the sink 2, and the other end of the overflow pipe 7 is directed to the side surface of the cylindrical container 4a of the deodorant drain trap 4 toward the deodorant cap 4b. It is connected to open. The overflow pipe 7 includes a short substantially horizontal pipe portion that projects horizontally from the overflow port 6, a vertical pipe portion that extends downward from the pipe portion, and a substantially horizontal portion that extends from the lower end of the vertical pipe portion. And a tube portion connected to the cylindrical container 4a, and an opening / closing valve 8 adapted to operate the handle 8a from below is attached to the tube portion.

  A ball chain 9 is fixed to the upper surface on the front wall side of the sink 2, and a rubber lid 10 for closing the drain port 3 formed on the bottom surface 2 a of the sink 2 is connected to the ball chain 9. . In the figure, 11 is a water tap or a hot water tap.

  For example, when cleaning a device to be cleaned such as a production tool, the on-off valve 8 is opened, the drain port 3 is closed with a lid 10, and water or hot water is supplied from a water tap or a hot water tap 11, so Store hot water in and clean the equipment to be cleaned. The device to be cleaned can also be cleaned with the lid 10 open.

  When the hot water in the sink 2 reaches the lower end edge of the overflow port 6, the hot water flows from the overflow port 6 through the overflow pipe 7 into the cylindrical container 4a of the deodorant drain trap 4 and from the lower end of the deodorant cap 4b. It flows into the space between the cap 4b and the drainage pipe 4c, flows into the drainage pipe 4c from the upper end of the drainage pipe 4c, and drains down through the drainage pipes 4c and 5.

  When the cleaning operation is completed, the lid 10 is removed from the drain port 3 through the ball chain 9. For this reason, the hot water in the sink 2 flows into the deodorant drain trap 4 from the drain port 3, flows into the space between the deodorant cap 4b and the drain pipe 4c from the lower end of the deodorant cap 4b, and from the upper end of the drain pipe 4c. The drainage pipe 4c flows into the drainage pipes 4c and 5 and is drained, and the water level in the cylindrical container 4a in the deodorizing drainage trap 4 is the upper end position of the drainage pipe 4c.

  When odor enters the deodorant drain trap 4 through the drain pipes 5 and 4c, the odor accumulates in the space inside the deodorant cap 4b, but water remains in the cylindrical container 4a up to the upper end position of the drain pipe 4c. Therefore, the odor accumulated in the space in the deodorizing cap 4b is blocked by the water accumulated in the cylindrical container 4a, and therefore the odor is prevented from entering the drain 2 from the drain port 3 to the sink 2 side.

  When the cleaning operation of the device to be cleaned is completed and hot water is drained from the sink 2, the sink 2 is cleaned, the drain port 3 of the sink 2 is closed again with the lid 10, and the opening / closing valve 8 is operated by operating the handle 8a. Close. For this reason, even if the water in the deodorant drain trap 4 is at a level lower than the lower end of the deodorant cap 4b, the odor enters the room from the sink 2 via the deodorant drain trap 4 and the overflow pipe 7 into the room. In addition, living pests such as cockroaches are prevented from entering the room from the sink 2 through the deodorizing drain trap 4 and the overflow pipe 7 from the outside.

Patent Document 1 is a prior art document related to the sink. This patent document 1 provides an overflow drain port that does not generate an air pull-in sound during drainage, and includes a valve that can be freely opened and closed above the overflow drain port. The valve has a specific gravity of 1 or less. The lid configured as described above prevents air from being drawn in from the overflow drain port.

  In the case of the sink structure shown in FIG. 8, since the on-off valve 8 is arranged below the sink 2, the on-off operation is difficult and the operability is poor, and even when the on-off valve 8 is closed, the on-off valve The germs that have propagated in the overflow pipe 7 between 8 and the overflow port 6 may enter the sink 2 and eventually enter the room.

  Moreover, the thing of patent document 1 is for preventing the air drawing sound at the time of drainage, and is not for preventing an odor and a living pest.

  In view of the above circumstances, an object of the present invention is to provide a sink structure that can easily and reliably prevent odors, living pests, and the like from entering a room from a sink.

  The sink structure according to claim 1 of the present invention is a sink structure having a drain outlet on the bottom surface of the sink and an overflow pipe through which water overflowed from the sink flows down, the lid closing the drain outlet, and the sink It is provided with a lid that closes an inlet portion of an overflow pipe through which overflowing water flows.

  The sink structure according to claim 2 of the present invention is a sink structure having a drain outlet on a bottom surface of the sink and an overflow pipe through which water overflowed from the sink flows down, a lid for closing the drain outlet, An opening / closing valve adapted to be opened / closed from the upper side of the sink is provided at the inlet of the overflow pipe through which overflowing water flows.

  The sink structure according to claim 3 of the present invention is a sink structure having a drain outlet on a bottom surface of the sink and having an overflow pipe through which water overflowed from the sink flows down, the lid closing the drain outlet, and the sink If water does not overflow from the sink to the vertical pipe section of the overflow pipe through which overflowing water flows, it closes by rotating due to the weight of the weight, and if the water overflows from the sink, the weight of the weight due to the force of the water Is provided with a check valve having vanes that are rotated and opened in a direction opposite to the rotating direction.

  In the sink structure according to claim 4 of the present invention, a deodorizing drain trap is provided below the drain outlet.

  According to the sink structure according to claims 1 to 4 of the present invention, not only the deodorizing drain trap and the indoor edge cut, but also the overflow pipe and the indoor edge cut can be easily and reliably performed. Can be easily and reliably prevented from entering the room from the sink, and the operation of confirming that the overflow pipe is blocked can be easily and reliably performed. For this reason, the reliability is improved in the sink structure of the present invention.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
1 to 3 show a first example of an embodiment implementing the sink structure of the present invention. In the figure, the same reference numerals as those in FIG. 8 denote the same parts, and the basic configuration is the same as the conventional one shown in the figure.
Thus, the feature of this illustrated example is that a round lid 12 made of rubber is provided in order to close the round hole-shaped overflow port 6 provided in the front wall surface 2 b of the sink 2. The lid 12 is connected to one end of the ball chain 13, and the other end of the ball chain 13 is fixed to the upper surface on the front wall side of the sink 2.

  The state where the ball chain 13 is fixed to the upper surface on the front wall side of the sink 2 is shown in FIGS. 2 and 3, in which 14 is a bracket attached to the upper surface on the front wall side of the sink 2, and 15 is a bracket for the ball chain 13. 14 is a joint fitting for connecting to the joint 14. The ball chain 9 is also fixed to the upper surface on the front wall side of the sink 2 in the same manner as the ball chain 13.

Next, the operation of the above-described embodiment will be described.
In the illustrated example, when the equipment to be cleaned is cleaned, for example, the drain port 3 is closed by the lid 10, the overflow port 6 is not closed by the lid 12, and is opened to the sink 2 by the water tap or hot water tap 11. Wash the water or hot water. When the level of hot water in the sink 2 rises from the lower edge of the overflow port 6, the hot water in the sink 2 passes through the overflow pipe 7 and the deodorizing drain trap 4 and is drained from the drain pipe 5 to the outside.

  Thus, when the cleaning operation is completed, the lid 10 is removed. For this reason, the water in the sink 2 flows into the drain pipe 5 from the drain port 3 through the cylindrical container 4a of the deodorizing drain trap 4 and the drain pipe 4c, and is drained from the drain pipe 5 to the outside. Thus, when the hot water in the sink 2 is drained, the sink 2 is washed, and then the drain port 3 is closed with the lid 10 and the overflow port 6 is closed with the lid 12.

  In this illustrated example, when the cleaning operation is not performed, the drainage port 3 is closed by the lid 10 and the overflow port 6 is closed by the lid 12, so that not only odors but also living pests and germs are discharged from the drainage pipe 5. It is possible to prevent entry into the room from the sink 2 through the deodorant drain trap 4 and entry into the room from the sink 2 through the deodorization drain trap 4 and overflow pipe 7 from the drain pipe 5. Further, since the overflow port 6 is closed by the lid 12, the handling becomes easier and the reliability of the sink structure is improved as compared with the case where the on-off valve 8 is provided in the overflow pipe 7 as shown in FIG. To do.

  4 and 5 show a second example of an embodiment for implementing the sink structure of the present invention. Thus, in the illustrated example, the on-off valve 8 is provided in the horizontal portion of the overflow pipe 7 in the vicinity of the overflow port 6 so that the handle 8a protrudes from the upper surface of the sink 2 on the front wall 2b side. . In the figure, the same reference numerals as those shown in FIG.

  In such a configuration, when the equipment to be cleaned is cleaned, the drain port 3 is closed by the lid 10, the on-off valve 8 is opened, and water or hot water is stored in the sink 2 by the water tap or hot water tap 11 to perform the cleaning work. To do.

  Thus, when the cleaning operation is completed, the lid 10 is removed. For this reason, the water in the sink 2 flows into the drain pipe 5 from the drain port 3 through the cylindrical container 4a of the deodorizing drain trap 4 and the drain pipe 4c, and is drained from the drain pipe 5 to the outside. Thus, when the hot water in the sink 2 is drained, the sink 2 is washed, and then the drain port 3 is closed with the lid 10, and the handle 8 a is operated to provide the overflow pipe 7 in the vicinity of the overflow port 6. The on-off valve 8 is closed.

  In the illustrated example, when the cleaning operation is not performed, the drain port 3 is closed with the lid 10 and the on-off valve 8 provided in the overflow pipe 7 is closed in the vicinity of the overflow port 6, so that not only odor but also life Pests and bacteria are prevented from entering the room from the sink 2 through the drain pipe 5 through the deodorized drain trap 4 and from the sink 2 through the sink 2 through the deodorized drain trap 4 and the overflow pipe 7. be able to.

  Further, since the opening / closing valve 8 can operate the handle 8a from the upper part of the sink 2, as compared with the case where the opening / closing valve 8 is provided at the lower part of the overflow pipe 7 and the handle 8a is operated from the lower part of the sink 2 as shown in FIG. And the handling of the on-off valve 8 becomes easy, and the reliability of the sink structure is improved.

  6 and 7 show a third example of the embodiment for implementing the sink structure of the present invention. Thus, in the illustrated example, the check valve 16 is provided at the upper position of the vertical portion of the overflow pipe 7. In the figure, the same reference numerals as those shown in FIG.

  As shown in FIG. 7, the check valve 16 includes a casing 17 and a disk-shaped blade 19 that is accommodated in the casing 17 so as to be rotatable with respect to the horizontal shaft 18. In addition, annular stoppers 17a and 17b having a substantially triangular cross section are formed on the inner peripheral surface of the casing 17. The stopper 17a is provided at a different height so as to be positioned above the stopper 17b, and a weight portion 19a is formed at the end of the blade 19 on the stopper 17a side.

  Thus, when the hot water in the sink 2 does not flow into the overflow pipe 7 from the overflow port 6, the blade 19 rotates on the weight portion 19a side in the clockwise direction in FIG. The upper surface of the blade 19 is in contact with the upper surface, and the upper surface of the lower end of the blade 19 is in contact with the lower surface of the stopper 17b. As a result, the overflow pipe 7 is closed.

  When hot water in the sink 2 flows into the overflow pipe 7 from the overflow port 6, the blade 19 rotates counterclockwise in FIG. 7 due to the weight of the hot water, and the upper end of the blade 19 is separated from the stopper 17a. The lower end of the blade 19 is separated from the stopper 17b. As a result, the blade 19 is opened and hot water can flow down the overflow pipe 7.

  At the time of cleaning the device to be cleaned, the drainage port 3 is closed by the lid 10 and water or hot water is stored in the sink 2 by the water tap or hot water tap 11 to perform the cleaning operation. In this case, the middle part of the overflow pipe 7 is blocked up and down by the vane 19 of the check valve 16 (see FIG. 7).

  If the level of the hot water in the sink 2 becomes higher than the lower edge of the overflow port 6 during the cleaning operation, the hot water flows into the overflow pipe 7 from the overflow port 6, and the flow force causes the blade 19 of the check valve 16 to move. 7, the hot water flows from the overflow pipe 7 into the drain pipe 5 through the cylindrical container 4a and drain pipe 4c of the deodorizing drain trap 4 and from the drain pipe 5 to the outside. Drained into

  Thus, when the cleaning operation is completed, the lid 10 is removed. For this reason, the water in the sink 2 flows into the drain pipe 5 from the drain port 3 through the cylindrical container 4a of the deodorizing drain trap 4 and the drain pipe 4c, and is drained from the drain pipe 5 to the outside. Thus, when the hot water in the sink 2 is drained, the sink 2 is washed, and then the drain port 3 is closed with the lid 10. When hot water does not flow into the overflow pipe 7 from the sink 2, the vane 19 of the check valve 16 rotates due to the weight of the weight portion 19a and closes as shown in FIG.

  In the illustrated example, when the cleaning operation is not performed, the drain port 3 is closed by the lid 10 and the check valve 16 provided in the overflow pipe 7 is closed in the vicinity of the overflow port 6, so that not only the odor, Prevents living pests and germs from entering the room from the drain 2 through the deodorant drain trap 4 and from the sink 2 and from the drain 2 through the deodorized drain trap 4 and the overflow pipe 7 to the room. can do.

  In addition, the check valve 16 automatically closes the blade 19 unless hot water flows into the overflow pipe 7, so that it is not necessary to manually open and close the valve. Reliability is improved.

  It should be noted that the sink structure of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention. The “water” includes not only water but also hot water or hot water only.
