BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the improvement of kitchen sinks, and more specifically, eliminates odors from garbage in a garbage box stored in a sink body and discharges the odor to a drain pipe side. The present invention also relates to a kitchen sink configured to reliably prevent backflow of odor, drainage, and the like from a drain pipe.

[0002]

2. Description of the Related Art In order to remove odors from garbage in a garbage box stored in the body of a kitchen sink, there is a kitchen sink configured to discharge the odor to a drain pipe side by an exhaust fan. Conventionally, various types have been proposed.

[0003]

[Problems to be solved by the present invention] However, the exhaust effect of kitchen odor by only the exhaust fan is insufficient.
When the exhaust fan is stopped, there is a problem that odor and drainage flow backward from the drain pipe to the sink side, so that dirty odor drifts in the kitchen, which is unpleasant and unsanitary.

The present invention has been developed with the object of solving the above-mentioned problems, and can eliminate odor even when the exhaust fan is stopped, as well as prevent the odor and drain water from flowing backward from the drain pipe. It is an object of the present invention to provide a comfortable and sanitary kitchen sink that can surely prevent the crawling of oily insect pests.

[0005]

As means for solving the above-mentioned problems and achieving the intended object, the present invention provides a kitchen sink body, a kitchen garbage box which is housed in and out of the body, A deodorizing device for kitchen waste discarded in the box, which communicates a storage portion of the kitchen waste box with a portion where the deodorizing device is provided, and a device such as a deodorant formed near the communication portion. An exhaust fan disposed between the communication section and the drain pipe, an exhaust pipe, and a backflow preventing member for odor, drainage, and the like from the drain pipe provided between the exhaust pipe and the drain pipe. A kitchen sink characterized by constituting the above-mentioned kitchen garbage deodorizing device was developed and adopted.

Further, in the present invention, in the kitchen sink constructed as described above, the installation part for the deodorant and the like is provided so that the deodorant and the like can be replaced. Developed and adopted kitchen sinks each composed of a check valve that was energized.

[0007]

In the kitchen sink constructed as described above, the odor generated from the garbage in the garbage box is eliminated by a deodorant or the like, and is reliably discharged to the drain pipe side by the exhaust fan. Even if an odor, drainage, or the like attempts to flow backward from the drain pipe due to an increase or the like, it is prevented by the backflow prevention member.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. A kitchen sink according to the present invention comprises a sink body 1 and a garbage box 2 which is housed in the body 1 so as to be able to enter and exit.
And a deodorizing device 3 for odor generated from kitchen waste.

Thus, the sink body 1 has a storage space 5 for various kitchen utensils having a plurality of doors 4 on the front.
, A water tank 6, and a mounting base plate 7 for kitchen utensils and the like connected to the side of the water tank 6, the base plate 7 having an upper end of an input pipe 9 having a kitchen waste input port 8. The input port 8 is configured to be opened and closed by a lid 10.

The kitchen garbage box 2 is located at a lower portion of the mounting table 7 and is housed in a storage 11 provided in the storage space 5 of the main body 1 via a rail 12 so as to be able to move in and out. The lower end of the input pipe 9 is connected to the top plate 11a of the storage 11 so that kitchen waste discarded from the input port 8 can be reliably inserted into the kitchen waste box 2.

Further, the deodorizing device 3 is communicated and connected from the upper portion of the storage section of the kitchen garbage box 2. In this embodiment, a mounting section 15 for the deodorant 14 formed near the communicating section 13 is provided. An exhaust fan 16 disposed close to the mounting portion 15; a flexible exhaust pipe 17 extending from the portion; a connecting pipe 19 for connecting the exhaust pipe 17 and the drain pipe 18; And a backflow prevention member 20 provided near the upper end connecting portion 19 for preventing odor and drainage from the drain pipe 18.

As shown in the enlarged view of FIG. 3, the check ring 20 includes a check valve 20a formed of rubber, plastic, or the like and having an umbrella-shaped cross section.
0a is biased in the direction of arrow A by a spring 20b which shuts off communication between the exhaust pipe 17 and the drain pipe 18. When the exhaust fan 16 is driven, the check valve 20a is actuated by the wind pressure. Push open against the spring 20b,
It is configured to discharge odor, air, and the like to the direction of arrow B, that is, to the drain pipe 18 side. In FIG. 2, 21 is a replacement opening / closing lid for the deodorant 14, 22 is a drive motor of an exhaust fan, 23 Indicates outlets. In addition, the arrangement relationship of each component of the deodorizing device 3 is not limited to the above embodiment, and the concept of the deodorizing agent 14 includes a fragrance,
Deodorants are also included.

Next, the use state and the like of the above embodiment will be described. The garbage discharged from the kitchen is directly stored in the garbage box 2 in the storage box 11 through the input port 8 or once in a garbage basket (not shown) at the drain port and then through the input pipe 9 through the input port 8. Discarded. The garbage in the garbage box 2 is taken out to the outside in a timely manner and discarded. However, since the deodorant 13 is provided, the generation of odor is small. By driving the 16, it can be discharged to the drain pipe 18 side.

Further, even if the drain pipe 18 is clogged or the amount of drain water temporarily increases, and the dirty odor flows back to the exhaust pipe 17 together with the drain water, the backflow provided between the exhaust pipe 17 and the drain pipe 18 By the check action of the check valve 20a which is spring-biased of the prevention member 20, the backflow of drainage and odor is reliably prevented,
In addition, crawling of pests such as oil insects can be prevented.

Although the main embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, but can achieve the object of the present invention and do not deviate from the gist of the present invention. Naturally, various design changes are possible.

[0016]

[Effect of the Invention] The present invention comprises a kitchen sink main body, a kitchen garbage box housed in the main body so as to be freely accessible, and a deodorizing device for kitchen garbage discarded in the box. A communication section between the storage section of the box and the arrangement section of the deodorizing device, and an installation section for a deodorant or the like formed near the communication section;
Deodorization of the garbage by the exhaust fan disposed between the communication portion and the drain pipe, the exhaust pipe, and the backflow preventing member for odor and drainage from the drain pipe provided between the exhaust pipe and the drain pipe. The present invention relates to a kitchen sink characterized by constituting an apparatus, and is used as described above, and has the following effects.

(1) The odor generated from the garbage collected in the garbage box is discharged to the drain pipe side by the exhaust fan of the deodorizing device and is erased by the deodorant or the like.
Discomfort and uncleanness due to odor can be remarkably improved.

(2) Even when the exhaust fan stops due to the presence of the deodorizing agent or the like, the odor can be effectively suppressed, and this effect is further improved by frequently replacing the deodorizing agent.

(3) Even if the drainpipe is clogged or the amount of drainage temporarily increases, and the dirty odor tries to flow back to the exhaust pipe along with the drainage, the backflow prevention provided between the exhaust pipe and the drainpipe is prevented. The check action of the check valve, which is biased by the spring of the member, reliably prevents the backflow of drainage and odor, and also prevents the crawling of pests such as oil insects, so that the environmental hygiene of the kitchen is kept extremely good. obtain.
