Abstract

<P>PROBLEM TO BE SOLVED: To solve the following problem; in spite of the occurrence of boiling with no water due to the incorrect action of a water flow switch, oscillation output does not stop and an ultrasonic vibrator is broken. <P>SOLUTION: The ultrasonic vibrator 2 is mounted on one end of the vibrator fitting part 1a of a running water housing 1 by a back member 3. An inflow port 1b for supplying a washing liquid to the ultrasonic radiation surface of the ultrasonic vibrator 2 is mounted on the side wall of the vibrator fitting part 1a. An inclined wall 1c diagonally formed from the other end of the vibrator fitting part 1a at a thickness almost equal to that of the side wall of the vibrator fitting part 1a is installed. A propagation medium holding member 4 made of a thin synthetic resin is mounted on the front of the ultrasonic vibrator 2 of the running water housing 1. A liquid ultrasonic propagation medium 5 is held between the propagation medium holding member 4 and the ultrasonic vibrator 2. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to an ultrasonic cleaning device that prevents empty cooking when no cleaning liquid is supplied into a running water housing.

    Conventionally, as this type of ultrasonic cleaning apparatus, as shown in FIG. 4, an ultrasonic transducer 2 is mounted on one end of a transducer mounting portion 1 a of the flowing water housing 1 by a back material 3. An inlet 1b for supplying the cleaning liquid to the ultrasonic radiation surface is attached to the side wall of the vibrator mounting portion 1a, and the thickness of the side wall of the vibrator mounting portion 1a from the other end of the vibrator mounting portion 1a is substantially the same. An apparatus is proposed in which an inclined wall 1c formed obliquely is provided, and an outlet 1d is formed at the narrowed end of the inclined wall 1c. In such an ultrasonic cleaning apparatus, empty cooking is prevented. For this purpose, a water flow switch is provided in the vicinity of the outlet 1d. When the cleaning liquid is insufficient, the water flow switch is operated to stop the oscillation output supplied to the ultrasonic vibrator 2.

However, in such an ultrasonic cleaning device, when the cleaning liquid is insufficient, foreign matter is clogged between the contact points of the switch, or the cleaning liquid supplied into the flowing water housing is insufficient due to malfunction of the water switch. Nevertheless, there is a problem in that the oscillation output is not stopped, the vibrator is in a no-load state, the cooking is performed, and the ultrasonic vibrator is destroyed.
Japanese Patent Application 2001-366432

  The problem to be solved is that, in the conventional ultrasonic cleaning device, the oscillation output does not stop and the ultrasonic transducer is destroyed due to the malfunction of the flowing water switch, even though empty cooking has occurred. It is.

  In the present invention, the ultrasonic transducer is mounted on the transducer mounting portion, the ultrasonic propagation medium is held on the ultrasonic radiation surface of the ultrasonic transducer by the propagation medium holding member, and the flowing water housing is from the vicinity of the propagation medium holding portion. An inclined wall provided with an outlet that is inclined obliquely and is narrowed at the end is formed, and a supply port for supplying the cleaning liquid is mounted on a side wall in the vicinity of the propagation medium holding member.

  In the ultrasonic cleaning apparatus of the present invention, by providing a propagation medium holding member on the front surface of the ultrasonic vibrator and holding the ultrasonic propagation medium, even if there is no cleaning liquid near the propagation medium holding member, the ultrasonic vibration There is an advantage that the child is not cooked by the ultrasonic propagation medium, and therefore the ultrasonic vibrator is not immediately destroyed even if the cleaning liquid is not supplied.

  In the present invention, the ultrasonic vibration medium is held in front of the ultrasonic transducer in the housing, and the cleaning liquid is supplied to the vicinity of the ultrasonic propagation medium. Since the load is applied by the ultrasonic propagation medium, the ultrasonic transducer is not destroyed.

  FIG. 1 is a perspective view of an ultrasonic cleaning apparatus according to an embodiment of the present invention. Reference numeral 1 is a flowing water housing, 2 is an ultrasonic vibrator, and 3 is a back material. In this embodiment, a propagation medium holding member 4 made of a thin synthetic resin is mounted on the front surface of the ultrasonic vibrator 2 of the flowing water housing 1, and the propagation medium holding member 4 and the ultrasonic vibrator 2 are attached. A liquid ultrasonic propagation medium 5 is held between the two.

  In the ultrasonic cleaning apparatus of the present embodiment configured as described above, the cleaning liquid is supplied from the inlet 1b by holding the ultrasonic propagation medium 5 by the propagation medium holding member 4 on the front surface of the ultrasonic transducer in this way. Even if it does not flow in, the ultrasonic vibration generated by the ultrasonic vibrator 2 is absorbed by the ultrasonic propagation medium 4, and therefore the ultrasonic vibrator 2 may be destroyed by empty cooking of the ultrasonic vibrator 2. Absent.

  In the above embodiment, the propagation medium holding member 4 is made of a thin synthetic resin. However, the propagation medium holding member 4 may be omitted if the ultrasonic propagation medium 5 is a gel.

It is side surface sectional drawing of the ultrasonic cleaning apparatus of the Example of this invention. It is sectional drawing of the other conventional ultrasonic cleaning apparatus.
