Problems to be solved by the invention
Accordingly, an object of the present invention is to provide an ultrasonic cleaning apparatus and a washing machine in which an object to be cleaned is easily placed in a water storage tub.
Solution for solving the problem
A first aspect of the present invention relates to an ultrasonic cleaning apparatus. The ultrasonic cleaning device of the present embodiment comprises: a water storage part provided with a water storage bucket capable of storing water; an ultrasonic wave generator disposed directly above the water storage tank, and configured to apply ultrasonic waves generated from a tip of the ultrasonic wave generator to an object to be cleaned placed in the water storage tank; a support unit for supporting the water storage unit so as to be movable in the up-down direction; and an elastic member disposed between the water storage unit and the support unit, and configured to provide an upward elastic force to the water storage unit.
According to the above configuration, when the object to be cleaned is placed in the water storage tank, the water storage section can be depressed to expand the interval between the ultrasonic wave generator and the bottom surface of the water storage tank. Thus, the user can easily insert the object to be cleaned between the water storage tub and the ultrasonic wave generator, and can easily place the object to be cleaned in the water storage tub.
The ultrasonic cleaning apparatus according to the present embodiment may further include: a housing accommodating the ultrasonic wave generator; and a protection part provided on the housing and surrounding the front end of the ultrasonic wave generator. In this case, the guard portion protrudes toward the water storage tub side from the distal end of the ultrasonic wave generator.
According to the above configuration, the portion near the ultrasonic wave generating body in the object to be cleaned can be sandwiched between the guard and the bottom surface of the water tank, and the guard can be pressed from below by the elastic force of the elastic member. Thus, the portion of the object to be cleaned near the ultrasonic wave generating body is easily stretched flat, and the ultrasonic wave from the ultrasonic wave generating body is easily applied to the near portion. Thus, the object to be cleaned is expected to be well decontaminated.
In the case of adopting the above-described structure, the following structure may be further adopted: the surface of the guard portion facing the bottom surface of the water storage tub has a concave-convex shape.
With such a configuration, the vibration generated by the operation of the ultrasonic wave generator propagates to vibrate the guard, and the object to be cleaned can be beaten and washed by the concave-convex portion. Thus, the object to be cleaned can be expected to be more decontaminated.
A second aspect of the present invention relates to a washing machine. The washing machine of this scheme possesses: the washing barrel is used for accommodating washings for washing; and an ultrasonic cleaning apparatus according to the first aspect.
According to the above configuration, the same effects as those of the ultrasonic cleaning apparatus of the first aspect can be obtained.

The fully automatic washing machine 1 can perform washing operations in various operation modes. In the washing operation, a washing process, an intermediate dehydrating process, a rinsing process, and a final dehydrating process are sequentially performed.
In the washing and rinsing processes, the pulsator 24 rotates rightward and leftward in a state where water is stored in the washing and dehydrating tub 22. By the rotation of the pulsator 24, a water current is generated in the washing and dehydrating tub 22. During the washing process, the laundry is washed by the generated water flow and the detergent contained in the water. During the rinsing process, the laundry is rinsed by the generated water flow.
The wash and dehydration tub 22 and the pulsator 24 integrally rotate at a high speed during the intermediate dehydration process and the final dehydration process. The laundry is dehydrated by the centrifugal force generated in the washing and dehydrating tub 22.
The fully automatic washing machine 1 can perform a washing operation of an object to be washed, which is a washing object, by the ultrasonic washing apparatus 50.
When the washing operation is started, the washing water is supplied from the reserve tank 60 to the water storage tub 210. When the supply of the washing water into the water storage tub 210 is completed, the user places the dirt adhering portion of the object to be washed, i.e., the washed portion, into the water storage tub 210 so as to be interposed between the water storage tub 210 and the ultrasonic wave generating body 110.
At this time, the user presses down the water storage part 200. For example, the user may pull the portion to be cleaned from both sides and press the water reservoir 200 with the portion to be cleaned in a tensioned state, or may press the water reservoir 200 with hands holding both sides of the portion to be cleaned. As shown in fig. 5, the water storage portion 200 moves downward against the elastic force of the coil spring 320, and the space between the ultrasonic wave generator 110 and the bottom surface 210a of the water storage tub 210 increases. Thus, the user can easily insert the portion to be cleaned between the water storage tub 210 and the ultrasonic wave generating body 110, and can easily place the portion to be cleaned inside the water storage tub 210.
In the case where the object to be cleaned has a thin texture, for example, the portion to be cleaned can be easily placed in the water storage tub 210 without expanding the interval between the ultrasonic wave generator 110 and the bottom surface 210a of the water storage tub 210, the water storage unit 200 does not have to be pushed down.
The washed portion of the washed object placed in the water storage tub 210 is soaked with the washing water, and the washing water soaked into the inside thereof oozes out of the surface. A thin water layer is formed on the surface of the portion to be cleaned, and the tip of the ultrasonic wave generator 110, that is, the tip of the vibration horn 112 is in contact with the water layer. The ultrasonic wave generator 110 operates to emit ultrasonic vibrations from the tip of the vibration horn 112. The ultrasonic vibration propagates to the water contained in the portion to be cleaned, and cavitation occurs in the water. By the effect of the cavitation, dirt is peeled from the cleaned portion. In this case, the detergency is increased by adding the detergent.
Effect of the embodiments >
According to the present embodiment, when the portion to be cleaned of the object to be cleaned is placed in the water storage tub 210, the water storage portion 200 can be depressed to expand the interval between the ultrasonic wave generating body 110 and the bottom surface 210a of the water storage tub 210. Thus, the user can easily insert the portion to be cleaned between the water storage tub 210 and the ultrasonic wave generating body 110, and can easily place the portion to be cleaned inside the water storage tub 210. Thus, the convenience of use for the user can be improved.
In particular, even in the case of washing a thick object to be washed, the portion to be washed can be easily placed in the water storage tub 210.
The embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and various modifications other than the above embodiments may be made.

Fig. 6 is a front cross-sectional view of an ultrasonic cleaning apparatus 50 according to modification 1. Fig. 7 (a) and (b) are a plan view and a cross-sectional view, respectively, of the shielding body 160 of modification 1.
In the ultrasonic cleaning apparatus 50 according to modification 1, a guard 160 is provided on the front end surface of the housing 120. The protector 160 is formed of a rubber member such as silicone, and is fixed to the front end surface of the housing 120 by an adhesive or the like. The shielding body 160 has a square plate shape having the same shape as the opening 141 and having an opening at the center, and is formed to correspond to the front end surface of the housing 120, and surrounds the front end of the ultrasonic wave generating body 110. The guard 160 protrudes toward the water storage tub 210 side from the front end of the ultrasonic wave generator 110. The shielding body 160 corresponds to the shielding portion of the present invention.
The lower end surface 160a of the guard 160 facing the bottom surface 210a of the water storage tub 210 has a wavy concave-convex shape 161. The concave-convex shape 161 is formed so as to extend over the entire area of the lower end surface 160a, that is, over the entire periphery of the opening.
As shown in fig. 6, in the ultrasonic cleaning apparatus 50 according to the modification 1, the portion near the ultrasonic wave generating body 110 of the object to be cleaned is sandwiched between the shielding body 160 and the bottom surface 210a of the water tank 210, and the shielding body 160 can be pressed from below by the elastic force of the coil spring 320. Thus, the portion in the vicinity of the ultrasonic wave generator 110 of the object to be cleaned is easily stretched flat, and the ultrasonic wave from the ultrasonic wave generator 110 is easily applied to the portion in the vicinity. Thus, the object to be cleaned is expected to be well decontaminated.
The lower end surface 160a of the guard 160 that contacts the object to be cleaned has a concave-convex shape 161, and the vibration of the ultrasonic vibrator 111 propagates to vibrate the guard 160, whereby the object to be cleaned can be beaten and washed by the concave-convex shape 161. Thus, the object to be cleaned can be expected to be more decontaminated.
In the above example, the waveform concave-convex shape 161 is formed on the entire region of the lower end surface 160a of the shield body 160. However, as shown in fig. 8 (a), the wavy concave-convex shape 161 may be provided in a partial region of the lower end surface 160a of the shield body 160. For example, as shown in fig. 8 (b) and (c), the concave-convex shape 161 may be formed instead of the waveform: the concave-convex shape 162 formed by a plurality of hemispherical protrusions is formed in the entire area or a partial area of the lower end surface 160a of the shielding body 160.
As shown in fig. 8 (d), the lower end surface 160a of the protector 160 may be a flat surface without having a concave-convex shape. In this case, although it is difficult to expect the effect of hammering and washing, it is expected that the portion in the vicinity of the ultrasonic wave generator 110 of the object to be washed will be stretched flatly.
In the above example, the shielding body 160 is formed separately from the housing 120. However, the shielding body 160 may be integrally formed with the housing 120, i.e., the cover 140. In this case, the cover 140 may be formed of a rubber material.
< other modification examples >)
In the above embodiment, the water storage portion 200 is supported by two support portions 310 extending forward from the left and right lower end portions of the main body portion 300. However, the structure of the support portion is not limited to the structure of the above embodiment, and may be any structure. For example, a flat plate-like support portion may be provided below the water storage portion 200.
In the above embodiment, the coil spring 320 is used to apply an upward elastic force to the water storage unit 200. However, a spring other than the coil spring 320 may be used, and an elastic member other than a spring such as rubber may be used.
In the above embodiment, the ultrasonic cleaning device 50 is provided in the fully automatic washing machine 1. However, the ultrasonic cleaning device 50 may be provided in a washing machine other than the fully automatic washing machine 1, for example, a drum washing machine. The ultrasonic cleaning device 50 may be provided in, for example, a full-automatic washing and drying machine or a drum-type washing and drying machine having a drying function. In a drum washing machine and a drum washing and drying integrated machine, a washing drum is composed of an outer drum and a drum arranged in the outer drum.
The embodiments of the present invention can be modified in various ways within the scope of the technical idea shown in the technical proposal.
