Abstract

(57) [Summary] [Object] The present invention provides an ultrasonic transducer for a washing machine used in a washing machine for jetting and washing a liquid. [Structure] The ultrasonic oscillator 4 has a vibrating plate 10 bonded to one surface of a piezoelectric ceramic 9 and a reinforcing material 12 bonded to the other surface of the piezoelectric ceramic 9. As a result, the ultrasonic transducer 4 can be prevented from warping, so that it can be easily attached to the portion of the washing machine that faces the liquid ejection port 3, and since there is no warping, the packing 13 can be attached to the washing machine.
It can be mounted airtightly via.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an ultrasonic vibrator for a cleaning machine used in a cleaning machine for cleaning an object to be cleaned by injecting a liquid from a liquid supply port.

[0002]

[Prior Art]

 The present applicant, as shown in FIG. 5, provides an ultrasonic cleaning machine 5 in which a cover 1 is provided with a liquid supply port 2 and a liquid ejection port 3 and an ultrasonic transducer 4 is provided on a surface facing the liquid ejection port 3. Proposed (see Japanese Patent Laid-Open No. 62-157300).

When the oscillation output is supplied from the oscillation circuit 6 to the ultrasonic oscillator 4 of the ultrasonic cleaning machine 5 and the liquid 7 is supplied to the liquid supply port 2, the liquid 7 ejected from the ultrasonic cleaning machine 5 causes the liquid to be covered. The washing object 8 can be washed.

[0004]

[Problems to be solved by the device]

 By the way, in the ultrasonic cleaner 5, as the ultrasonic vibrator 4, a piezoelectric ceramic 9 to which a vibration plate 10 such as tantalum or quartz is bonded is used as shown in FIG. Even if one piece of piezoelectric ceramics 9 is bonded to the vibration plate 10, the ultrasonic vibrator 4 warps due to the difference in contraction rate. When it is adhered to, there is a problem that the warp becomes large and it is difficult to mount it on the ultrasonic cleaning machine 5.

[0005]

[Means for Solving the Problems]

 The present invention has a liquid supply port and a liquid ejection port, an ultrasonic transducer is mounted facing the liquid ejection port, and a driving voltage is applied to the ultrasonic transducer to supply the liquid from the liquid supply port. In a cleaning machine for cleaning an object to be cleaned by ejecting a liquid from a liquid ejection port, the ultrasonic transducer has a vibrating plate bonded to one surface of piezoelectric ceramics and reinforced on the other surface of the piezoelectric ceramics. It is a glued material.

[0006]

[Action]

 In the present invention, not only does the warp not occur at all by bonding the vibrating plate to one surface of the piezoelectric ceramic and the reinforcing material that does not cause warping to the other surface, but also the reinforcing material to the ultrasonic transducer. By attaching the, it becomes easy to attach to the ultrasonic cleaner.

【Example】

 1 and 2 are configuration diagrams of an ultrasonic transducer according to one embodiment of the present invention. Reference numeral 9 is a piezoelectric ceramic, and 10 is a vibration plate made of tantalum, quartz, or the like, and these configurations are the same as those in the conventional example. Although not described here, in this embodiment, the vibrating plate 10 is bonded to one surface of the piezoelectric ceramic 9 and the reinforcing material 12 is bonded to the other surface of the piezoelectric ceramic 9.

In the embodiment of FIGS. 1 and 2, two piezoelectric ceramics 9 are attached to the vibration plate 10, and the insulating material 11 for preventing discharge is interposed between the piezoelectric ceramics 9. One piezoelectric ceramics 9 may be bonded to the vibration plate 10, or two or more piezoelectric ceramics 9 may be bonded to the vibration plate 10.

Since the ultrasonic transducer of the present embodiment configured as described above is integrated and not warped, as shown in FIGS. 3 and 4, the cover 1 having the liquid supply port 2 and the liquid ejection port 3 is provided. The ultrasonic transducer 4 can be easily mounted in the cover 1 by inserting the ultrasonic transducer 4 into the stepped portion via the packing 13 and pressing the ultrasonic transducer 4 with the spring 15 provided on the lid 14 of the cover 1.

Further, one end of the spring 15 is connected to the piezoelectric ceramics 9 of the ultrasonic oscillator 4, and the other end of the spring 15 is connected to the oscillation circuit 16, and the other terminal of the oscillation circuit 16 is connected to the cover 1 The washing machine is constructed by connecting to the electrode 17 connected to the other terminal of the piezoelectric ceramics 9 provided inside.

In this ultrasonic cleaning machine, when the liquid is supplied from the liquid supply port 2 and the oscillation output is supplied from the oscillation circuit 16 to the piezoelectric ceramics 9 of the ultrasonic vibrator 4, the liquid is ejected from the liquid ejection port 3, It is possible to clean the object to be cleaned provided facing the liquid ejection port 3.
