[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a sink device with an exhaust function used for, for example, biological and chemical experiments.
[0002]
[Prior art]
2. Description of the Related Art A sink device used for biological and chemical experiments or cleaning of precision machine parts is provided with an exhaust function to prevent the emission of bad odors and harmful gases.
[0003]
In that case, an exhaust port is provided in a rear portion of the opening edge of the sink facing the operator, and the exhaust port is sucked into the exhaust duct.
[0004]
[Problems to be solved by the invention]
However, in the conventional configuration, since the exhaust port is opened forward, when water (or other liquid) jumps in the sink during a cleaning operation or the like, the splash enters the exhaust duct from the exhaust port. there were. In addition, a large amount of water may flow into the exhaust duct by mistakenly turning the shower toward the exhaust port.
[0005]
Therefore, the exhaust duct is formed so as to allow water (liquid) to enter, and a drain port is provided at the bottom of the exhaust duct, which is normally closed by a valve, and the valve is opened as necessary.
[0006]
However, since the drain port is located at the bottom of the exhaust duct, in order to operate the valve, a person must bend and sink under the sink, so that the drainage work from the exhaust duct is hung up. It is troublesome. Therefore, the frequency of drainage from the exhaust duct should be as low as possible.
[0007]
In addition, if a large amount of liquid accumulates in the suction duct, there is a problem that a foul odor is generated or the duct is easily corroded even after the work is completed, and in order to suppress this, liquid can enter the exhaust duct as much as possible. Less (preferably none) is desirable.
[0008]
However, the conventional configuration cannot meet such a demand, and a considerable amount of liquid has entered the exhaust duct. There was a problem.
[0009]
An object of the present invention is to improve such a current situation.
[0010]
[Means for Solving the Problems]
The sink device of the present invention comprises a sink with an upward opening on which an operator works from the front side , an exhaust duct provided on the back side of the sink, and a back panel that rises upward from the rear part of the sink, Between the rear plate of the sink and the back panel, there is an exhaust port for sucking the air inside the sink into the exhaust duct, while the back panel is provided with a faucet.
[0011]
A baffle plate that prevents or suppresses splashes generated in the sink from entering the exhaust port is provided at a portion of the rear portion of the sink near the rear plate so as to extend downward from the back panel. Further, the exhaust duct extends below the sink, and a suction pipe extending in the left-right direction as viewed from the operator is disposed in a portion of the exhaust duct below the sink. A number of suction holes are formed along the longitudinal direction.
[0012]
[0013]
[Operation and effect of the invention]
According to the present invention, by providing a shielding means, it is possible to prevent or remarkably prevent splashes from entering the exhaust port during a cleaning operation or a large amount of liquid flowing directly from the shower into the exhaust port. it can.
[0014]
As a result, even if liquid accumulates in the exhaust duct, it is possible to reduce the frequency of the work of draining the liquid and reduce the burden on the operator, and it is possible to cause a foul odor and corrosion to occur in the exhaust duct. Can be prevented or significantly suppressed.
[0015]
Further, even if the shower is directed to the exhaust port by mistake, it is an advantage that the liquid can be surely prevented from flowing into the exhaust duct from the exhaust port.
[0016]
By the way, the air in the exhaust duct needs to be sucked to the outside.For example, the suction duct or the like may be simply connected to the suction port of the exhaust duct, but in this case, the suction force at the suction port of the exhaust duct is strong, As the distance from the suction port increases, the suction force becomes weaker.
[0017]
With a suction duct as in the present invention, on the other hand, to be able to equalize the suction force to the exhaust duct, an advantage that can suction efficiency improvement above.
[0018]
DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings.
[0019]
(1). First embodiment (FIGS. 1 to 4)
1 to 4 show the first embodiment. 1 is a perspective view of the entire sink device, FIG. 2 is a sectional view taken along line II-II in FIG. 1, FIG. 3 is a partial front view, and FIG. 4 is a sectional view taken along line IV-IV in FIG.
[0020]
The sink device of this embodiment is used for biological experiments, for example, and includes a sink (a sink main body) 1 in which a work space 2 is greatly opened upward. The sink 1 is supported by four legs 3, and a work table 4 having a large number of holes is disposed on the left and right sides of the work space 2. At the bottom of the work space 2 is provided a scissors 5.
[0021]
A back panel 6 is attached to the sink 1, and attached devices such as a faucet 7 and a shower 8 are attached to the back panel 6. A large space is open below the sink 1, and the tank 9 and the like can be stored in this space.
[0022]
An exhaust duct 10 is provided on the back surface of the sink 1. The exhaust duct 10 extends to below the sink 1, and a suction pipe 11 extending in the left-right direction passes through the lower portion of the exhaust duct 10. As shown in FIG. 4, the suction pipe 11 has a number of suction holes 12 opened upward. Thus, since the suction port is vacant along the longitudinal direction of the exhaust duct 10, the suction force with respect to the exhaust duct 10 can be equalized over the entire length. In this example, the suction holes 12 are the same size and are spaced at equal intervals.
[0023]
As shown in FIG. 3, the left and right ends of the exhaust duct 10 enter inside the left and right side surfaces of the sink 1, and the exhaust duct 10 is in a state where the end 11 a of the suction pipe 11 does not protrude from the left and right side surfaces of the sink 1. It protrudes from.
[0024]
If you use the sink device only one is connected to a suction duct to either of the left and right ends of the suction pipe 11 and the other (may be connected to a suction duct at both ends) may be Fusage plug .
[0025]
When arranging a plurality of sink devices side by side, adjacent suction pipes 11 are connected by a flexible hose or the like, that is, each sink device or suction pipe is connected in series, and the sink device located at the extreme end is connected. A suction duct 13 may be connected to the suction pipe 11. Alternatively, each suction pipe 11 may be connected to one suction duct arranged on the back side of each sink device or the like via a branch duct.
[0026]
A drainage pipe (drainage pipe) 14 is disposed below the exhaust duct 10, and a drainage port 15 provided at the bottom of the sink 1 is connected to this by a hose or pipe.
[0027]
As shown in FIG. 3, the bottom surface of the exhaust duct 10 is inclined so that the left and right central portions thereof are lowered, and a drain port is provided at the lowest portion, and the drain port and the drain pipe 14 are connected to the drain pipe. 16 is connected. The drain pipe 16 is provided with a valve 17 for opening and closing it.
[0028]
The drain port does not necessarily need to be connected to the drain pipe 14, and may be exposed downward to draw the liquid into a tank or a bucket.
[0029]
As shown in FIG. 2, by lowering the height of the rear plate 1 a constituting the sink 1, an exhaust port 18 extending over the entire length of the work space is opened between the rear plate 1 a and the back panel 6. Yes.
[0030]
And the baffle plate 19 extended over substantially the full length of the working space 2 is arrange | positioned as an example of a shielding means in the site | part of the near side of the rear surface board 1a. Therefore, an exhaust passage 20 that communicates with the exhaust port 18 and opens downward is formed between the baffle plate 19 and the rear plate 1a. The baffle plate 19 is preferably a corrosion-resistant one such as a synthetic resin plate.
[0031]
When work such as cleaning is performed in the work space 2, splashes are scattered toward the exhaust port 18, but by providing the baffle plate 19, the splashes may enter the exhaust duct 10 through the exhaust port 18. Remarkably suppressed. Even if the shower 8 is mistakenly directed to the exhaust port 18, water (cleaning liquid) does not flow into the exhaust port 18.
[0032]
For this reason, the frequency of the operation | work which opens the valve | bulb 17 of the drain pipe 16 and drains from the exhaust duct 10 can be reduced significantly compared with the past. The baffle plate 19 may be inclined backward or forwardly as viewed from the side. Moreover, it is also possible to attach so that it can rotate centering on an upper end so that the attitude | position in a side view can be changed.
[0033]
(2). Second embodiment (FIG. 5)
By the way, by using the suction pipe 11, the suction force at each part of the exhaust port 18 can be equalized. However, since the suction pipe 11 is sucked from one end thereof, the suction force becomes smaller toward the other end of the suction pipe 11. For this reason, it is difficult to completely eliminate the tendency that the suction force from the exhaust port 18 becomes nonuniform in each part along the frontage direction.
[0034]
In this regard, in the second embodiment shown in FIG. 5, the suction force 12 is further increased in size by increasing the size of the suction hole 12 toward the front side in the suction direction. The same effect can be obtained by changing the pitch P of the suction holes 12 instead of or in addition to changing the size of the suction holes 12.
[0035]
When suction is performed from both ends of the suction pipe 11, the size of the suction holes 12 is increased toward the left and right intermediate portions of the suction pipe 11, or the drilling pitch P of the suction holes 12 is increased. 11 may be made smaller as it goes to the left and right middle part, or both may be combined.
