Abstract

PURPOSE:To perform perfect rinsing without using a large amount of water even when a material to be washed has a complicated shape by providing an ultrasonic vibrator to a rinsing tank. CONSTITUTION:A drain solenoid valve 13 for introducing a definite amount of the water from a water supply pump 12 and a water level sensor 16 are provided to a rinsing tank 4 and an ultrasonic vibrator 17 is provided to the bottom part of the rinsing tank 4. A basket 2 receiving a material to be washed is subjected to ultrasonic washing and subsequently fed to the rinsing tank 4 to be placed on the basket receiving stand 9 of the rinsing tank 4. The water supply pump 12 begins to operate in such a state that the basket 2 falls to a predetermined position in the rinsing tank 4 and the drain solenoid valve 13 is closed to feed water in the rinsing tank 4. Next, the ultrasonic vibrator 17 provided to the bottom part of the rinsing tank 4 is driven and ultrasonic waves are emitted into the rinsing tank 4 in which the material to be washed is immersed. By this method, it is prevented that a part to which water is not sufficiently applied is generated in the material to be washed and perfect rinsing can be performed by a relatively small amount of water.

Description

[Detailed description of the invention] <Industrial application field> The present invention relates to an ultrasonic cleaning device.

<Conventional technology> Generally, in hospitals, cleaning and drying of medical instruments such as syringes and forceps are carried out continuously.
An ultrasonic cleaning device with six rinsing and drying baths may be used.

FIG. 3 is a block diagram of the rinsing tank 4° portion of such an ultrasonic cleaning device.

In the figure, 4o is a rinsing tank, 2 is a basket in which the equipment to be cleaned is stored after being washed in a washing tank (not shown), 9 is a basket receiver, 20 is a sower nozzle that spouts water for rinsing, and 12 is a Water supply pump, 21 is drain port, I8
14 is a water supply pipe, and 15 is a drain pipe.

In the hiring process, first, the basket holder 9 on which the basket 2 is placed is lowered to a predetermined position within 4 degrees of the hiring tank, the water supply pump I2 starts operating, and the shower nozzle 2
Rinse by squirting water from 0. The spouted water flows out into the drain pipe 15 from the drain port 2I at the bottom of the rinsing tank 4°. The operation of the water supply pump 12 is controlled by a timer, and is configured to stop after a certain period of time has elapsed.

<Problems to be Solved by the Invention> However, in the conventional ultrasonic cleaning device that performs rinsing by ejecting water from the shower nozzle 20, the equipment to be cleaned may, for example, be interlocked like a pin, or
If the shower nozzle 20 has a complicated shape, there may be areas where the water from the shower nozzle 20 does not reach enough, leaving cleaning agent behind, or a large amount of water may be required to completely clean the area. There are disadvantages such as having to use .

The present invention has been made in view of the above-mentioned points, and provides an ultrasonic cleaning device that allows complete rinsing without using large amounts of water even if the equipment to be cleaned has a complicated shape. The purpose is to provide.

Means for Solving the Problems> In order to achieve the above object, the present invention provides a cleaning tank for ultrasonically cleaning the equipment to be cleaned, a hired tank for rinsing the equipment to be cleaned after ultrasonic cleaning, and In an ultrasonic cleaning apparatus including a drying tank for drying the equipment to be cleaned after irrigation, the rinsing tank includes applying ultrasonic waves to the rinsing tank in which the equipment to be cleaned after ultrasonic cleaning is immersed. Effect of being provided with an ultrasonic vibrator that emits ultrasonic waves> According to the above configuration, since the hired tank is provided with an ultrasonic vibrator that emits ultrasonic waves, rinsing after cleaning is performed using ultrasonic waves. Compared to the conventional method of rinsing by spraying water from a shower nozzle, even complex-shaped equipment can be thoroughly rinsed without using a large amount of water.

<Example> Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic diagram of an ultrasonic cleaning apparatus according to an embodiment of the present invention.

This ultrasonic cleaning device 1 includes a cleaning tank 3 for ultrasonically cleaning instruments to be cleaned such as syringes and forceps stored in a basket 2, and a rinsing tank for rinsing instruments to be cleaned after ultrasonic cleaning as described below. It is provided with a tank 4 and a drying tank 5 for drying the equipment to be cleaned after being used.

The cleaning pa3 is provided at its bottom with an ultrasonic vibrator 6 for radiating ultrasonic waves to perform ultrasonic cleaning, and the drying tank 5 is provided with hot air to dry the equipment to be cleaned after irrigation. A heater 7 and a fan motor 8 are provided for this purpose.

In addition, 9 is a basket receiver on which the basket 2 is placed, IO is a carry-in conveyor for carrying the basket 2 into the cleaning equipment, 11 is a carry-out conveyor for carrying the basket 2 out of the machine after completing each process, and 12 is a carry-in conveyor for carrying the basket 2 out of the machine. A water supply pump supplies water to six tanks 3 and 4, 13 is a drain solenoid valve that drains water from six tanks 3 and 4, I4 is a water supply pipe, and 15 is a drain pipe.

FIG. 2 is a block diagram showing details of the rinsing tank 4 shown in FIG. 1, and corresponds to the conventional example shown in FIG. 3.

The ultrasonic cleaning device 1 of this embodiment is configured as follows in order to perform complete rinsing without using a large amount of water.

That is, the rinsing tank 4 is provided with a drain electromagnetic valve I3 and a water level sensor 16 in order to introduce a certain amount of water from the water supply pump 12 into the irrigation tank 4, and furthermore, at the bottom thereof, An ultrasonic vibrator 17 that emits ultrasonic waves is provided in the rinsing tank 4 in which the equipment to be cleaned after ultrasonic cleaning is immersed, and a shower nozzle 20 as in the conventional example is not provided. In addition, in this FIG. 2, 18 is a swing mechanism, and I9 is an overflow pipe for draining overflow water.

Next, the operation of the ultrasonic cleaning apparatus I having the above configuration will be explained.

The basket 2 containing the equipment to be cleaned is subjected to ultrasonic cleaning in the cleaning tank 3 in the same manner as in the past, and then transported to the rental tank 4, and the basket holder of the irrigation tank 4 is placed on the stand 9. Ru.

Then, the basket 2 is lowered to a predetermined position in the rinsing tank 4 by a lifting mechanism (not shown), and with the drain electromagnetic valve 13 closed, the water supply pump 12 starts operating to supply water into the rinsing tank 4. be done. When the water level reaches the upper limit position, the water level sensor 16 detects that the water pump 12
operation stops.

Next, the ultrasonic transducer 17 provided at the bottom of the rinsing tank 4 is driven by an ultrasonic oscillator (not shown) to emit ultrasonic waves into the rinsing tank 4 in which the equipment to be cleaned is immersed, thereby rinsing the equipment. It will be done. The operation of the ultrasonic oscillator is controlled by a timer, and after a certain period of time has elapsed, the operation is stopped and the drain electromagnetic valve 13 is opened to drain the water in the rinsing tank 4.

Since rinsing is performed by emitting ultrasonic waves into the irrigating tank 4 in which the equipment to be cleaned is immersed, it is different from the conventional example in which rinsing is performed by spraying water from the shower nozzle 20. Therefore, it is possible to completely rinse the equipment with a relatively small amount of water, without causing parts of the equipment to be washed to be insufficiently exposed to water.

In addition, when the drainage is completed and the hiring process ends, the basket 2 swings up and drains the water, and returns to the drying tank 5.
After drying with hot air as in the conventional method, the material is transported out of the apparatus by the transport conveyor 11.

<Effects of the Invention> As described above, according to the present invention, since rinsing after cleaning is performed using ultrasonic waves, equipment to be cleaned having a complicated shape can be completely rinsed with relatively less water than in the conventional example. be able to.
