Description
The present invention relates to an ultrasonic cleaner for cleaning an object to be cleaned by applying ultrasonic vibration to a liquid immersed in the object to be cleaned. The present application claims priority based on Japanese Patent Application No. 2016-133814 filed on July 6, 2016, the contents of which are incorporated herein by reference.
Conventionally, as disclosed in the following Patent Document 1, there has been known a washing machine comprising a washing tub 20a for containing an object to be cleaned and a washing liquid, a plurality of vibration elements 31 to 33 attached to the washing tub, Oscillators 41 to 43 and a control unit 60 for controlling each oscillator so that a plurality of oscillators output signals having the same phase to a plurality of oscillation elements. In this apparatus, as an oscillation mode from an oscillator, it is possible to output a modulated wave by FM modulation or AM modulation instead of a sinusoidal wave.
As an oscillation mode of an ultrasonic wave, generally, single, dual, FM modulation, pulse, etc. are known and have different characteristics. However, the conventional ultrasonic cleaner can be operated only in a single oscillation mode. In other words, it is operated only in the preset oscillation mode, and the oscillation mode can not be changed during operation. In addition, during operation in a predetermined oscillation mode (for example, a single oscillation mode), the frequency and the output of the ultrasonic wave are not changed. For this reason, for example, there is a possibility that a sufficient cleaning effect can not be obtained at the top or corner of the object to be cleaned. Therefore, it is required to perform effective cleaning effectively utilizing characteristics of each oscillation mode, cleaning with a change in oscillation, and cleaning according to needs.
Further, in the conventional ultrasonic cleaner, since the ultrasonic oscillation in a specific oscillation mode is continuous, the flow of the stored liquid is hardly changed and it is difficult to remove the contamination even if the contamination is floated from the object to be cleaned by the ultrasonic vibration. That is, there is room for improvement in the transfer of contamination from the object to be cleaned to the storage liquid.
SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an ultrasonic cleaner capable of effectively cleaning the ultrasonic cleaning apparatus, effectively cleaning the ultrasonic cleaning apparatus, and cleaning the ultrasonic cleaning apparatus according to needs. It is another object of the present invention to provide an ultrasonic cleaner that changes the flow of a retentate during ultrasonic cleaning to smoothly carry out contamination from a retentate to a retentate.

(a) Single oscillation mode = oscillation mode of short-wave (output and frequency is constant). Generates strong cavitation, eliminating stubborn contamination.
(b) Dual oscillation mode = oscillation mode of two frequencies (two waves in close proximity). Suppresses the rectification of cavitation and propagates the ultrasonic waves to the far side.
(c) FM oscillation mode = oscillation mode with frequency modulation (ie FM modulation). The stationary wave position is moved to reduce irregularities in cleaning.
(d) Pulse oscillation mode = an oscillation mode in which a short-circuited frequency (typically one cycle) is intermittently oscillated. This is effective for accelerating the degassing to reduce the attenuation of the ultrasonic waves.
(e) AM oscillation mode = oscillation mode using amplitude modulation (output change) (i.e., AM modulation wave).
(f) FM / AM oscillation mode = oscillation mode with frequency modulation and amplitude modulation (ie simultaneous change of frequency and output).

In either case, it is preferable that the control means controls the
Hereinafter, an example of a method of operating the ultrasonic cleaner 1 of the present embodiment will be described in detail.

It is not necessary to individually set the oscillation mode, the frequency and the output of the ultrasonic wave for each operation mode individually. As described above, for example, when the oscillation mode is set, the frequency and / or the output are automatically set . It is also preferable to change at least one of the oscillation mode, the frequency and the output of the ultrasonic wave during the transition from the heating step S2 to the ultrasonic cleaning step S3 when the
In this embodiment, the ultrasonic cleaning S31 of the first set time (for example, 30 seconds) in at least the first operation mode (for example, dual oscillation mode, 800W) and the second operation mode The ultrasonic cleaning S32 of the second set time (for example, 29 seconds) in the mode (for example, mode 800W) is performed. It is also possible to add ultrasonic cleaning S33 (or ultrasonic cleaning of the fourth set time in the fourth operation mode) of the third set time in the third operation mode (for example, the single oscillation mode) The ultrasonic cleaning operation in the set number of operation modes can be executed sequentially in total. Then, when the operation mode of the set number is almost executed, the ultrasonic cleaning is performed again in order from the ultrasonic cleaning S31 of the first set time in the first operation mode.
In the ultrasonic cleaning operation (including the ultrasonic cleaning step S3 as well as the water supply step S1 or the heating step S2, when the
In addition, the adjacent operation modes (that is, the operation modes to be performed and the operation modes immediately thereafter) in the same ultrasonic cleaning operation may be the same oscillation mode (that is, the same mode type) if they have different frequencies or outputs. For example, if the first operation mode is a dual oscillation mode, the second operation mode is a single oscillation mode, and the third operation mode is a single oscillation mode (only frequency and / or output is different) as the second operation mode .
As described above, at least one of an oscillation mode of an ultrasonic wave, a frequency (a modulation method in the case of FM modulation) and an output (a modulation method in the case of AM modulation) are set to be different between the front and rear operation modes.
Either way, in the ultrasonic cleaning step S3, the ultrasonic cleaning is repeated while switching a plurality of operation modes in time. In this embodiment, every time the operation modes (that is, the operation mode of the set number) (For example, set at 1 to 5 seconds, and in this embodiment, 1 second). That is, in Fig. 3, after the ultrasonic cleaning S32 of the second set time in the second operation mode (when the ultrasonic cleaning S33 of the third set time in the third operation mode is performed, etc.), the ultrasonic oscillator 10 ) Is stopped for the set idle time, and then returns to the first first oscillation mode.
Thus, in the ultrasonic cleaner 1 of the present embodiment, the
However, the stop of the ultrasonic vibration (the temporary interruption of the ultrasonic wave oscillation during the ultrasonic wave oscillation) is not limited to every time when the plurality of operation modes are almost finished, At the time of switching from the first operation mode to the second departure operation mode, and / or at the time of switching from the second operation mode to the third operation mode). Alternatively, during the oscillation in the predetermined operation mode, the

For example, a controller (for example, a touch panel) is also connected to the controller, and the presence or absence of ultrasonic oscillation in the water supply step S1 or the heating step S2 can be set prior to the start of operation. At this time, when ultrasonic oscillation is performed, one or more of the oscillation mode, the output, and the frequency may be changed. In the ultrasonic cleaning step S3, the output or frequency for each operation mode can be set by the type of the oscillation mode in each operation mode in Fig. This makes it possible to perform optimum cleaning in accordance with the object to be cleaned.
The ultrasonic cleaner 1 of the present invention is not limited to the configuration (including the control) of the embodiment described above, and can be changed appropriately. More particularly, the present invention relates to an ultrasonic oscillator (10) for operating the ultrasonic oscillator (9), an ultrasonic oscillator (9) provided in the cleaning tank (2) And control means for ultrasonically cleaning the object to be cleaned by controlling the
