Problems solved by technology

Therefore, since the transmission efficiency of ultrasonic vibration is low, if the output of the ultrasonic vibrator 522 is small, sufficient air bubbles will not be generated in the washing liquid sprayed from the nozzle 525, and sufficient washing by cavitation may not be obtained. force
On the other hand, if the output of the ultrasonic vibrator 522 is too high, as in the ultrasonic humidifier, the cleaning liqu

no. 1 approach

[0048] figure 1 The configuration of the ultrasonic cleaning device 10 according to the first embodiment of the present invention is shown in . The ultrasonic cleaning device 10 has a casing 12 formed of insulating synthetic resin or the like. Inside the housing 12 are provided an ultrasonic vibrator 14 , an ultrasonic transmitter 16 to which the ultrasonic vibrator 14 is bonded, a drive circuit 18 for driving the ultrasonic vibrator 14 , and the like.

[0049] The casing 12 is composed of a substantially cylindrical main body 22, a nozzle unit 24 connected to one end of the main body 22, and the like. A water supply pipe 20 is connected to the nozzle portion 24 , and a cleaning liquid is supplied to an internal cavity (cavity) 26 of the nozzle portion 24 from a cleaning liquid tank (not shown). The nozzle portion 24 has, for example, a truncated cone shape, and its cross-sectional area becomes smaller as it is formed closer to the tip of the casing 12 . In addition, the t...

[0062] under, Figure 4 The configuration of the ultrasonic cleaning device 10 according to the second embodiment of the present invention is shown in . In addition, the description of the part which is substantially the same as the said 1st embodiment and the 2nd embodiment is abbreviate|omitted, and only a different point is demonstrated.

[0063] Such as Figure 4 As shown, in the ultrasonic cleaning device 10 according to the second embodiment, the ultrasonic transmitting body 16 is substantially in the shape of a truncated cone, and at least the part protruding into the cavity 26 of the nozzle part 24 is formed closer to the nozzle-side end, that is, The cross-sectional area of ​​the ultrasonic radiation surface 16A in a direction parallel to the joint surface with the ultrasonic vibrator 14 gradually decreases. In addition, the shape of the nozzle portion 24 is formed into a substantially truncated cone shape in which the cross-sectional area becomes narrower as it app...

no. 3 approach

[0086] Next, the configuration of the ultrasonic cleaning device 10 according to the third embodiment of the present invention will be described. In the third embodiment, the ultrasonic cleaning device 10 is a battery-type device. Note that descriptions of substantially the same parts as those in the above-described embodiments will be omitted, and only differences will be described.

[0087] exist Figure 21 In the ultrasonic cleaning device 10 shown in the figure, a rechargeable storage battery 19 and a pump 46 are arranged inside the main body 22 of the casing 12. In addition, at the rear portion of the main body 22, a washing liquid for storing the washing liquid is detachably installed. tank 48. In this way, by providing the cleaning solution tank 48 in the ultrasonic cleaning device 10 itself to form a battery-type device, it is possible to provide an ultrasonic cleaning device excellent in portability and operability.

Abstract

In an ultrasonic washer for washing by splaying washing toward an object to be washed or a portion to be washed from a front end of a nozzle, a part of an ultrasonic wave propagation member connected to an ultrasonic transducer is protruded into a cavity of the nozzle into which the washing is filled in order to propagate ultrasonic vibration generated by the ultrasonic transducer to the washing efficiently. Furthermore, the ultrasonic wave propagation member is formed so that a cross-sectional area becomes gradually smaller as approaching to the front end thereof, so that the ultrasonic vibration is converged to the end face of the ultrasonic wave propagation member. Still furthermore, a length of the ultrasonic transducer and the ultrasonic wave propagation member is made to be integral multiplication of a half-wavelength of ultrasonic standing wave oscillation, and the end face of the ultrasonic wave propagation member from which the ultrasonic wave is emitted to the washing is disposed at a position of antinode of the ultrasonic standing wave oscillation where the amplitude becomes the largest.

Description

technical field [0001] The present invention relates to a washing device using ultrasonic vibration, and more particularly, to an ultrasonic washer for washing objects to be washed or places to be washed by spraying washing liquid (washing) propagating ultrasonic vibration energy from nozzles. Background technique [0002] For example, in the Japanese Patent Application Publication No. 6-218337, it is proposed that Figure 37 The illustrated ultrasonic cleaning device 520 is an ultrasonic cleaning device 520 that sprays cleaning liquid given energy of ultrasonic vibration from a nozzle to clean the object to be washed or the place to be washed. [0003] Existing ultrasonic cleaning device 520 is by drive circuit 521, by the ultrasonic vibrator 522 driven by drive circuit 521, is used to transmit the ultrasonic transmission body 523 of the ultrasonic vibration that ultrasonic vibrator 522 produces, the cone (cone) that is connected with ultrasonic transmission body 523 ) 524,...
