Description

Pot and dishwasher using ultrasound}

The present invention relates to a pan and dishwashing apparatus using ultrasonic waves, and more specifically, prevents leakage of water between the parts and the coupling portion of the washing tank even when used for a long period of time, and makes installation and replacement of ultrasonic vibrators easy and quick. It relates to a pot and dishwashing apparatus using ultrasonic waves that can be performed.

In general, an ultrasonic dishwasher is designed to wash dishes by installing an ultrasonic vibrator on the bottom of the washing water, and vibrating the washing water in the washing tank by ultrasonic vibration. 1 is a cross-sectional view showing the configuration of a pot and dishwashing apparatus utilizing such ultrasonic waves. The ultrasonic cleaner is made of a washing tank 100 having a through hole 102 penetrating through the bottom surface and a tubular shape with an open lower end, and A flange 122 is provided between the diaphragm 120 coupled to the through hole 102 under the bottom surface of the washing tub 100, and between the flange 122 of the diaphragm 120 and the lower surface of the bottom of the washing tub 100 The interposed ring-shaped packing 110 and the flange 122 of the diaphragm 120 are pressed in close contact with the packing 110, so that the diaphragm 120 is placed under the bottom surface of the cleaning tank 100. A plurality of stud bolts 130 fixed to the through hole 102 of the, an ultrasonic vibrator 125 attached to the upper surface of the diaphragm 120 inside the diaphragm 120, and a wire 133 to the vibrator 125 ). It consists of an ultrasonic oscillator 135 electrically connected through.

According to the pot and dish washing apparatus using such ultrasonic waves, when a signal obtained by oscillating and amplifying the frequency of ultrasonic waves is transmitted from the ultrasonic oscillator 135, the vibrator 125 vibrates and the washing water vibrates, and accordingly, the washing water vibrates. As a result, the dishes are washed.

However, in the pan and dish washing apparatus using such ultrasonic waves, the vibration plate 120 is coupled to the through hole 102 of the washing tank 100 by a plurality of bolts 130, and when used for a long time, the vibration of the ultrasonic vibrator 125 As the bolt 130 is released by the bolt 130, since the space between the through hole 102 and the vibration plate 120 of the washing tank 100 is not properly sealed, there is a problem in that water leakage occurs. In addition, the vibration plate 120 is fastened with bolts 130 to approximately four places of the flange 122 and installed in the washing tank 100, since it is difficult to fasten the fastening portions of each bolt 130 with the same pressing force, During use, there is a problem in that water leakage occurs to one side of the bolt 130, and the pressing force of a certain portion of the four bolts 130 is too high, and the packing 110 may be partially damaged. In addition, since the dishwasher needs to be mounted on the washing tub 100 by fastening the vibrating plate 120 to a plurality of bolts 130, there is a problem that installation and maintenance work is cumbersome, and the vibrator 125 has high frequency. Since the electric wire 133 for supplying power is connected, the vibrator 125 must be mounted on the lower surface of the diaphragm 120, and it is difficult to separately replace the ultrasonic vibrator 125 in case of damage or failure.

The present invention has been proposed in view of the above-described problems, and in the present invention, since the sealing between each component and the coupling portion of the washing tank is not released due to vibration of the vibrator, leakage between each component and the coupling portion of the washing tank during use It is an object of the present invention to provide a pan and dishwashing apparatus using ultrasonic waves that are prevented from occurring and can be installed and replaced easily and quickly.

As described above, in the present invention, the outer body is screwed to the circumference of the inner body inserted in the through hole of the cleaning tank, so that the flange-shaped locking protrusion of the inner body is applied to the packing provided in the circumference of the through hole of the cleaning tank. Since it is closely adhered, the pressure between the inner body and the packing is not released by the vibration of the ultrasonic vibrator even after a long period of use, there is an advantage of preventing water leakage between the through hole of the cleaning tank and the inner body during use. In addition, the present invention prevents the packing from being damaged by applying excessive pressing force to a part of the packing due to the fact that the locking jaws of the inner body are closely coupled to the packing by the same pressing force, so that any part of the packing does not leak water. I can. In addition, since the pan and dish washing apparatus using ultrasonic waves is a work of fastening a plurality of fasteners, the outer body can be screwed onto the circumference of the inner body without attaching each part to the through hole of the washing tank. , The installation work is simple and quick, and the vibrator is not connected by the power line and is operated by the induced electromotive current of the secondary coil, so when the vibrator is damaged, the vibration unit with an ultrasonic vibrator built-in without removing the whole part Since only parts need to be replaced, there is an advantage that the replacement work of the ultrasonic vibrator is quick and easy.

In addition, in the present invention, a buffer member is interposed between the coupling jaw of the vibration unit and the locking jaw of the inner body, so that noise generated when the vibration unit vibrates is absorbed by the buffer member to minimize noise, and vibration Since the vibration unit and the surrounding parts are prevented from being damaged by the shock of the city, the lifespan can be extended.
