Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a sink equipped with an ultrasonic cleaning function.

(Devised technology and its problems) Conventional ultrasonic cleaning equipment reduces vibration by welding a connecting bolt to the outer surface of the bottom of a single-tank structure sink body, and attaching an ultrasonic vibrator to this connecting bolt by screwing it. The child is fixed to the bottom of the sink body.

However, in the above configuration, since the sink body is usually about 1 mm thick, traces of welding the connecting bolts are exposed on the surface side. Since it is attached to the outside surface, even if the vibrator is screwed onto the connecting bolt and tightened strongly, a gap will remain between the bottom outer surface and the vibrator, making it difficult to effectively transmit the vibration of the vibrator to the sink body. was not completed.

(Technical Issues) The technical issues of this invention are to prevent welding marks of connection bolts from being exposed on the surface of the sink body, and to
The vibrator is attached to the outer surface of the sink body without any gaps.

(Means for solving the technical problem) The means taken by the present invention to solve the above-mentioned technical problem is that the sink body has a double structure consisting of a sink tank and an outer tank, and the sink body has a double structure consisting of a sink tank and an outer tank. A gap is provided in between to accommodate water, and a flat part is formed in the outer tank, and a connecting bolt is welded to the outer surface of the flat part, and an ultrasonic transducer is screwed onto the connecting bolt. It is fixed.

(Function) According to the above means, when the vibrator is operated, the flat surface of the outer tank to which the vibrator is attached vibrates slightly together with the vibrator, and this vibration is transmitted to the sink tank via the water in the gap. Ru. When the sink vibrates, the water stored in the sink vibrates slightly, and the vibrating water removes dirty water adhering to the surfaces of dishes and the like.

Further, the vibrator screwed onto the connecting bolt is fixed to the outer surface of the flat part of the outer tank in a state where it is completely in close contact with the outer surface of the flat part of the outer tank.

(Effects) As described above, in this invention, the sink body has a double structure, and the flat surface of the outer tank is formed into a flat shape, so that the vibrator can be fully adhered to any arbitrary location on the external surface of the flat part. This allows the vibration of the vibrator to be efficiently transmitted to the outer tank.
A strong cleaning effect can be ensured.

In addition, since the structure is configured so that water is stored in the gap between the sink tank and the outer tank, even if the user accidentally activates the vibrator, the vibrator will not be activated by the water in the gap. It can be cooled and protected, and since the vibrator is in full contact with the outer surface of the flat surface of the outer tank, the heat of the vibrator can be efficiently dissipated to the outer tank and the water in the gap. .

Furthermore, since the connecting bolts for screwing and fixing the vibrator are welded to the flat surface of the outer tank, welding marks of the connecting bolts will not be exposed on the sink tank exposed to the outside.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The ultrasonic cleaning sink A shown in FIG. 1 is constructed by attaching an ultrasonic vibrator 7 to the bottom of a sink body A', and is placed next to a large sink B.

The sink body A' has a double structure consisting of a sink tank 1 for storing dishes, etc., and an outer tank 2 provided so as to surround the outer periphery and bottom of the sink tank 1 from the outside.
A gap 3 is provided between the holes 2 and 2 to accommodate water.

Sink tank 1 is a large sink B using a stainless steel plate.
Each corner is formed by a large curved surface, and an opening 7 for fitting the drain fitting main body 8 is opened in the center of the bottom surface, and an opening 7 is formed in the upper part of the circumferential surface. An outlet 5a of an overflow hole 5, which will be described later, is provided.

On the other hand, the outer tank 2 is arranged under the peripheral wall plate 2a with a gap 3 between the bottom surface of the sink tank 1 and a curved peripheral wall plate 2a that surrounds the outer peripheral surface of the sink tank through a gap 3 of a predetermined width. The flat bottom plate 2b is welded around the entire edge, and the upper edge of the peripheral wall plate 2a is connected to the sink 1.
In addition to welding to the back side of the opening rim, the opening rim at the center of the bottom plate 2b is welded along the back side of the opening 7 mouth rim of the sink tank 1. By this, sink tank 1 and outer tank 2
and the gap 3 provided between the two tanks 1 and 2 is kept watertight.

As shown in FIG. 3, ten connecting bolts 6 for attaching the vibrator 7 are scattered on the outer surface of the bottom plate 2b of the outer tank 2, and the upper end is fixed with the tip of the bolt 6 facing downward. The outer surface of the bottom plate 2b is welded and fixed to the outer surface of the bottom plate 2b. Therefore, the welding marks of the connecting bolts 6 are not exposed on the surface of the sink tank 1.

A vibrator 7 is screwed and attached to each connecting bolt 6, and the top surface of the vibrator 7 is a flat bottom plate 2b.
Tighten until it is firmly attached to the outside surface.

As described above, since the bottom plate 2b of the outer tank 2 is made of a flat surface, the upper surface of each vibrator 7 can be completely brought into close contact with the outer surface of the bottom plate 2b. Thereby, the vibration of the vibrator 7 can be effectively transmitted to the bottom plate 2b, and the heat of the vibrator 7 can be efficiently released to the outer tank 7 and the water in the gap 3.

Figures 4 to 6 show the overflow hole 5 opened at the upper limit position of the water level on the peripheral surface of the sink body A'.
It shows.

The overflow hole 5 is for draining water flowing out from the outlet 5a of the sink tank 1 from the connecting body 5c. The connecting body 5c is attached via a packing 10 to the outside of the outlet 5b which is provided in the outer tank 2 at a location corresponding to the outlet 5a of the sink tank 1. Further, a perforated plate 12 is fitted into the recess 11 around the outlet 5a of the sink tank 1, and bolts 13, 13 are inserted between both ends of the perforated plate 12 and both ends of the flange 5c' of the connecting body 5c, Nuts 14, 14 are screwed together to sandwich the sink tank 1 and the outer tank 2 and tighten them together.

In addition, a predetermined number of washers 15 are interposed as spacers between the sink tank 1 and the outer tank 2 in the bolts 13, 13 described above, so that the gap 3 is not collapsed when the nuts 14, 14 are tightened. It is configured to maintain a predetermined width.

Therefore, the water flowing out from the outlet 5a of the sink tank 1 flows into the gap 3, and when the gap 3 is filled, the water flows from the outlet 5b of the outer tank 2 to the connecting body 5c.
The gap 3 is always filled with water flowing from the outlet 5a.

In addition, a drain plug 2 is provided on the outer surface of the bottom plate 2b of the outer tank 2.
0 is provided, and the water in the gap 3 is drained from this drain plug 2.
It is designed to be able to drain water more completely than before.

As described above, the wastewater flowing into the connecting body 5c passes through the overflow hose 16 connected to the connecting body 5c and is sent to the drain fitting main body 8 fitted into the opening 4 of the sink tank 1. Then, this drainage water passes through the hose 17 and flows into the drainage fitting body 18 of the large sink B in the same way as the drainage from the drain port 9 opened on the top surface of the drainage fitting main body 8, and together with the drainage from the large sink B, the drainage pipe ( (not shown).
In addition, the water drained from the drain valve 20 is also drained from the connecting pipe 1.
9 and flows into the drainage fitting main body 18 to be drained. Incidentally, the drain valve 15 may be opened and closed by a solenoid valve (not shown).

When each vibrator 7 of the ultrasonic cleaning sink A configured as described above is operated, the bottom plate 2 along with the vibrator 7 is activated.
b vibrates slightly, and this vibration is transmitted to the sink tank 1 through the water filled in the gap 3, causing the water stored in the sink tank 1 to vibrate slightly.

Dirt adhering to dishes and the like placed in the sink 1 is cleanly removed by the slightly vibrating water.

Incidentally, since the outer tank 2 of the sink main body A' described above is composed of two members, the peripheral wall plate 2a and the flat bottom plate 2b, the bottom part can be formed as a completely flat part, and the bottom plate 2b can be formed as a completely flat part. It is possible to set the plate thickness to accommodate vibration.

In the illustration, the wall plate 2a has a curved surface, but it goes without saying that it may be made into a rectangular shape with a flat portion and the vibrator 7 attached to this portion as well.
