Description

超声波清洗装置及洗衣机Ultrasonic cleaning device and washing machine 技术领域Technical field
本发明涉及一种波清洗装超声置及具备该超声波清洗装置的洗衣机。The invention relates to an ultrasonic device of a wave cleaning device and a washing machine equipped with the ultrasonic cleaning device.
背景技术Background technique
专利文献1中记载了一种洗衣机，其在上面板中的洗涤物的投入口的周围，例如投入口的前侧配置有超声波清洗装置。超声波清洗装置具备能蓄水的贮水桶和具有位于贮水桶的正上方的超声波发生体的超声波发生单元。被清洗物的污垢附着部分被设置在蓄有水的贮水桶内从而开始清洗运转。由超声波发生体产生的超声波能量作用于被水浸透的污垢附着部分从而污垢被剥离。 Patent Document 1 describes a washing machine in which an ultrasonic cleaning device is arranged around an inlet for laundry in an upper panel, for example, in front of the inlet. The ultrasonic cleaning device includes a water storage bucket capable of storing water and an ultrasonic generation unit having an ultrasonic generator located directly above the water storage bucket. The dirt adhering part of the object to be cleaned is set in the water storage bucket with water, and the cleaning operation is started. The ultrasonic energy generated by the ultrasonic generator acts on the dirt adhered part soaked by water, and the dirt is peeled off.
在如上所述的超声波清洗装置中，可以采用如下结构：贮水桶与上面板分体形成，包括贮水桶和超声波发生单元的单元的位置以清洗运转时上述单元向投入口的内侧突出且非清洗运转时上述单元被收纳在投入口的周围的方式被切换。在采用这样的结构的情况下，即使清洗运转时水从贮水桶飞溅，飞溅的水也容易落入洗涤桶内，不容易飞到洗衣机外。此外，在不进行清洗运转时，上述单元不容易妨碍洗涤物从投入口投入。In the above-mentioned ultrasonic cleaning device, the following structure can be adopted: the water storage bucket and the upper panel are formed separately, and the position of the unit including the water storage bucket and the ultrasonic generating unit is such that the unit protrudes to the inside of the input port during cleaning operation and is not cleaned. During operation, the way in which the unit is stored around the inlet is switched. In the case of adopting such a structure, even if water splashes from the water storage tub during the washing operation, the splashed water easily falls into the washing tub and does not easily fly outside the washing machine. In addition, when the washing operation is not performed, the above-mentioned unit does not easily hinder the loading of laundry from the input port.
蓄于贮水桶的水通过与贮水桶相连的排水路被排出。在排水路设置有将排水口闭塞的可开闭的阀体，通过打开该阀体从贮水桶排水。如上所述，在采用上述单元的位置被切换为清洗运转时和非清洗运转时的结构的情况下，在结束一次清洗运转后还要继续进行清洗运转时，用户将上述单元维持在清洗运转的位置。贮水桶的水还能继续用于清洗运转。因此，采用在上述单元位于清洗运转的位置时不进行排水且在上述单元返回非清洗运转时的位置时进行排水的结构是希望提高对用户的便利性。此外，有时会想在清洗运转的位置更换贮水桶的水，这种情况下，希望能容易地换水。The water stored in the water storage bucket is discharged through the drainage path connected to the water storage bucket. An openable and closable valve body that closes the drain port is provided in the drain path, and the water is drained from the water tank by opening the valve body. As described above, when the position of the unit is switched between the cleaning operation and the non-cleaning operation, the user maintains the unit in the cleaning operation when the cleaning operation is continued after the completion of the cleaning operation. position. The water in the storage bucket can continue to be used for cleaning operations. Therefore, it is desired to improve the convenience for users by adopting a structure in which water is not drained when the unit is in the position of the washing operation, and water is drained when the unit is returned to the position during the non-washing operation. In addition, sometimes it is desirable to change the water in the water storage bucket at the location of the washing operation. In this case, it is desirable to be able to change the water easily.

在贮水部200的后部设置有用于固定装接于主体部300的贮水部200使其不向前方脱离的锁定机构280。锁定机构280具有爪部281和按钮282。爪部281被未图示的弹簧向上方施力，当按下按钮282时爪部281下降，当松开按钮282时爪部281返回当初的位置。A locking mechanism 280 for fixing the water storage unit 200 attached to the main body 300 so as not to detach forward is provided at the rear of the water storage unit 200. The lock mechanism 280 has a claw 281 and a button 282. The claw 281 is urged upward by a spring not shown. When the button 282 is pressed, the claw 281 descends, and when the button 282 is released, the claw 281 returns to its original position.
贮水部200从前方装接于主体部300。在贮水部200的里侧，于右端部和左 端部分别设置有***部205，主体部300的左右导轨部301***这些***部205，由此贮水部200被导轨部301引导。贮水部200的左侧的后部穿过主体部300的开口部302。此外，锁定机构280的爪部281与主体部300的***口303的上缘抵接而被按下，穿过***口303。当贮水部200向主体部300的装接完成时，爪部281返回当初的位置，在主体部300的里侧与***口303的上缘卡合。由此，贮水部200相对于主体部300无法向前方脱离。在使贮水部200从主体部300脱离时，按下锁定机构280的按钮282，爪部281下降。由此，爪部281与***口303的上缘的卡合被解除。通过将贮水部200向前方拉出，贮水部200从主体部300脱离。The water storage part 200 is attached to the main body part 300 from the front. On the inner side of the water storage unit 200, insertion portions 205 are provided at the right and left ends, respectively, and the left and right rail portions 301 of the main body 300 are inserted into these insertion portions 205, whereby the water storage portion 200 is guided by the rail portions 301. The left rear part of the water storage part 200 passes through the opening 302 of the main body part 300. In addition, the claw portion 281 of the lock mechanism 280 abuts against the upper edge of the insertion port 303 of the main body portion 300 and is pressed down, and passes through the insertion port 303. When the attachment of the water storage portion 200 to the main body 300 is completed, the claw portion 281 returns to the original position and engages with the upper edge of the insertion port 303 on the inner side of the main body 300. Thereby, the water storage part 200 cannot be separated forward from the main body part 300. When the water storage part 200 is detached from the main body part 300, the button 282 of the lock mechanism 280 is pressed, and the claw part 281 descends. Thereby, the engagement between the claw portion 281 and the upper edge of the insertion port 303 is released. By pulling the water storage unit 200 forward, the water storage unit 200 is separated from the main body 300.
在贮水部200装接于主体部300的状态下，超声波发生体110的振动变幅杆112的顶端面112a的位置比贮水桶210的上表面的位置稍低，振动变幅杆112的顶端部呈稍微进入贮水桶210内的状态。In the state where the water storage unit 200 is attached to the main body 300, the position of the tip surface 112a of the vibration horn 112 of the ultrasonic generator 110 is slightly lower than the position of the upper surface of the water tank 210, and the tip of the vibration horn 112 The part is slightly entering the water storage bucket 210.

The washing water supplied from the automatic input mechanism 90 flows in from the inflow port 64 and is stored in the storage tank 60. The water storage capacity of the storage tank 60 is larger than the water storage capacity of the water storage bucket 210. For example, water having a water storage capacity exceeding twice the water storage capacity of the water storage tank 210 can be stored in the storage tank 60. In addition, the storage tank 60 corresponds to the storage part of this invention.
供给阀400为电磁阀。贮留箱60的左箱61的流出口和右箱62的流出口与供给阀400的入口连接。供给阀400的出口与供给喷嘴500的入口连接。The supply valve 400 is a solenoid valve.

The outlet of the supply valve 400 is connected to the inlet of the supply nozzle 500.
供给喷嘴500由树脂材料形成，从供给阀400向前方延伸，其顶端部500a 向下方弯曲。在顶端部500a的下表面形成有放出口501。The supply nozzle 500 is formed of a resin material, extends forward from the supply valve 400, and its tip portion 500a is bent downward. A discharge port 501 is formed on the lower surface of the tip portion 500a.
如图8所示，在超声波清洗部100和贮水部200收纳于收纳部17的状态下，供给喷嘴500贯通主体部300的开口部302，其顶端部500a位于贮水桶210的前部。另一方面，如图9所示，在超声波清洗部100和贮水部200被拉出到投入口14的内侧的状态下，供给喷嘴500的顶端部500a位于贮水桶210的后部。As shown in FIG. 8, in a state where the ultrasonic cleaning unit 100 and the water storage unit 200 are housed in the storage unit 17, the supply nozzle 500 penetrates the opening 302 of the main body unit 300, and its tip portion 500 a is located at the front of the water storage bucket 210. On the other hand, as shown in FIG. 9, in a state where the ultrasonic cleaning unit 100 and the water storage unit 200 are pulled out to the inside of the input port 14, the tip portion 500 a of the supply nozzle 500 is located at the rear of the water storage bucket 210.
在收纳部17，于超声波清洗装置50的下方配置有排水承接部70。排水承接部70具有上表面和前表面敞开的近似方形的碟状。排水承接部70的底面以后部变低的方式倾斜。在排水承接部70的右侧面，于后部的下端且于底面最低的位置形成有排出孔71。在从排出孔71向右延伸的连接管73连接有排水管72。In the storage portion 17, a drainage receiving portion 70 is arranged below the ultrasonic cleaning device 50. The drain receiving portion 70 has a substantially square dish shape with an open upper surface and a front surface. The bottom surface of the drain receiving portion 70 is inclined such that the rear portion becomes lower. On the right side surface of the drain receiving portion 70, a drain hole 71 is formed at the lower end of the rear portion and at the lowest position on the bottom surface. A drain pipe 72 is connected to a connection pipe 73 extending rightward from the discharge hole 71.
在排水承接部70的后表面以沿左右方向排列的方式设置有沿上下方向延伸的两根肋74。两根肋74的高度位置与贮水部200的阀可动构件240的后板部244的高度位置大致相等。肋74相当于本发明的抵接部。Two ribs 74 extending in the vertical direction are provided on the rear surface of the drain receiving portion 70 so as to be aligned in the left-right direction.

全自动洗衣机1中进行各种运转模式的洗涤运转。洗涤运转中，按顺序执行清洗过程、中间脱水过程、漂洗过程以及最终脱水过程。The fully automatic washing machine 1 performs washing operations in various operation modes. During the washing operation, the washing process, the intermediate dehydration process, the rinsing process and the final dehydration process are executed in order.
清洗过程和漂洗过程中，在洗涤脱水桶22内蓄有水的状态下，波轮24向右方向和左方向旋转。通过波轮24的旋转，洗涤脱水桶22内产生水流。清洗过程中，通过产生的水流和水中所含的洗涤剂，洗涤物被清洗。漂洗过程中，通过产生的水流，洗涤物被漂洗。During the washing process and the rinsing process, the pulsator 24 rotates in the right direction and the left direction in a state where water is stored in the washing and dehydrating tub 22. Through the rotation of the pulsator 24, a water flow is generated in the washing and dehydrating tub 22. During the cleaning process, the laundry is cleaned by the generated water stream and the detergent contained in the water. During the rinsing process, the laundry is rinsed by the generated water flow.
中间脱水过程和最终脱水过程中，洗涤脱水桶22和波轮24一体地高速旋转。通过洗涤脱水桶22中产生的离心力的作用，洗涤物被脱水。During the intermediate dehydration process and the final dehydration process, the washing and dehydration barrel 22 and the pulsator 24 rotate together at a high speed. The laundry is dehydrated by the centrifugal force generated in the washing and dehydrating tub 22.
在清洗过程中的供水时，液体洗涤剂由自动投入机构90自动投入洗涤脱水桶22内。这时，首先，第一三通阀93切换至使供给管92与供给泵95连通的状态。而且，第二三通阀97切换至使上游侧供给路96b与下游侧供给路96c连通的状态。当供给泵95工作时，洗涤剂盒91内的液体洗涤剂通过泵的作用被排出。被排出的液体洗涤剂如图2的虚线箭头所示，穿过供给管92、第一三通阀93以及供给泵95被送至洗涤剂供给路96，蓄于洗涤剂供给路96的上游侧供给路96b。供给泵95工作预先规定的时间，由此，预先规定的量的液体洗涤剂蓄于上游侧供给路96b。When water is supplied in the washing process, the liquid detergent is automatically put into the washing and dehydrating tub 22 by the automatic input mechanism 90. At this time, first, the first three-way valve 93 is switched to a state in which the supply pipe 92 and the supply pump 95 communicate. Then, the second three-way valve 97 is switched to a state in which the upstream side supply path 96b and the downstream side supply path 96c communicate. When the supply pump 95 operates, the liquid detergent in the detergent box 91 is discharged by the action of the pump. The discharged liquid detergent is sent to the detergent supply path 96 through the supply pipe 92, the first three-way valve 93 and the supply pump 95 as shown by the dotted arrow in FIG. 2, and is stored on the upstream side of the detergent supply path 96 Supply path 96b. The supply pump 95 is operated for a predetermined time, and thereby a predetermined amount of liquid detergent is stored in the upstream side supply path 96b.
接着，第一三通阀93切换至使副供水路94与供给泵95连通的状态，副阀83被打开。如图2的实线箭头所示，来自水龙头的水穿过副供水路94、第一三通阀93以及供给泵95流向洗涤剂供给路96，冲走液体洗涤剂。被水冲走的液体洗涤剂如图2的单点划线箭头所示，与水一起从洗涤剂供给路96的供给口96a投入洗涤脱水桶22内。当向洗涤脱水桶22内的液体洗涤剂的投入完成时，副阀83被关闭。Next, the first three-way valve 93 is switched to a state in which the auxiliary water supply passage 94 and the supply pump 95 are communicated, and the auxiliary valve 83 is opened. As shown by the solid arrow in FIG. 2, the water from the faucet passes through the auxiliary water supply path 94, the first three-way valve 93, and the supply pump 95 to flow to the detergent supply path 96 to flush away the liquid detergent. As shown by the one-dot chain arrow in FIG. 2, the liquid detergent washed away by the water is poured into the washing and dehydrating tub 22 from the supply port 96 a of the detergent supply path 96 together with the water. When the injection of the liquid detergent into the washing and dehydrating tub 22 is completed, the sub valve 83 is closed.
然后，进行向洗涤脱水桶22内的供水。打开主阀82，来自水龙头的水流过主供水路84从注水口84a放出到洗涤脱水桶22内。当洗涤脱水桶22内的水位达到规定的清洗水位时，关闭主阀82，供水结束。Then, water supply into the washing and dehydrating tank 22 is performed. The main valve 82 is opened, and the water from the faucet flows through the main water supply path 84 and is discharged from the water injection port 84a into the washing and dehydrating tub 22. When the water level in the washing and dewatering tub 22 reaches a predetermined washing water level, the main valve 82 is closed, and the water supply ends.
进而，全自动洗衣机1中进行由超声波清洗装置50实现的清洗运转。在洗涤衬衫等被清洗物时，当该被清洗物局部含有顽固的污垢时，用户会在洗涤之前使用超声波清洗装置50进行被清洗物的局部清洗。Furthermore, in the fully automatic washing machine 1, the cleaning operation by the ultrasonic cleaning device 50 is performed. When washing objects to be cleaned such as shirts, if the object to be cleaned partially contains stubborn dirt, the user will use the ultrasonic cleaning device 50 to perform local cleaning of the object to be cleaned before washing.
在进行清洗运转的情况下，如图3的(b)所示，用户将超声波清洗装置50从收纳部17拉出，使超声波清洗部100和贮水部200移动至运转位置。如图9所示，阀切换机构230借助弹簧260的施加力，经由阀可动构件240向闭塞方向对阀体220施力。由此，阀体220将排水口211闭塞，排水口211呈锁闭的状态。In the case of the cleaning operation, as shown in FIG. 3(b), the user pulls the ultrasonic cleaning device 50 from the storage unit 17 to move the ultrasonic cleaning unit 100 and the water storage unit 200 to the operating position. As shown in FIG. 9, the valve switching mechanism 230 urges the valve body 220 in the closing direction via the valve movable member 240 by the urging force of the spring 260. As a result, the valve body 220 closes the drain port 211, and the drain port 211 is in a locked state.
用户进行规定的开始操作以开始清洗运转。The user performs a prescribed start operation to start the cleaning operation.
当清洗运转开始时，最初通过自动投入机构90进行向贮留箱60内的清洗水的供给。即，首先，第一三通阀93切换至使供给管92与供给泵95连通的状态。而且，第二三通阀97切换至使上游侧供给路96b与清洗水供给路98连通的状态。当供给泵95工作时，洗涤剂盒91内的液体洗涤剂通过泵的作用被排出。如图2的虚线箭头所示，从洗涤剂盒91排出的液体洗涤剂到达洗涤剂供给路96，蓄于洗涤剂供给路96的上游侧供给路96b。供给泵95工作预先规定的时间，由此，预先规定的量的液体洗涤剂蓄于上游侧供给路96b。When the washing operation starts, the supply of washing water into the storage tank 60 is performed by the automatic input mechanism 90 first. That is, first, the first three-way valve 93 is switched to a state in which the supply pipe 92 and the supply pump 95 communicate. Then, the second three-way valve 97 is switched to a state in which the upstream side supply path 96b and the washing water supply path 98 communicate with each other. When the supply pump 95 operates, the liquid detergent in the detergent box 91 is discharged by the action of the pump. As shown by the dotted arrow in FIG. 2, the liquid detergent discharged from the detergent box 91 reaches the detergent supply path 96 and is stored in the upstream side supply path 96 b of the detergent supply path 96. The supply pump 95 is operated for a predetermined time, and thereby a predetermined amount of liquid detergent is stored in the upstream side supply path 96b.
接着，第一三通阀93切换至使副供水路94与供给泵95连通的状态，副阀83被打开。如图2的实线箭头所示，来自水龙头的水穿过副供水路94、第一三通阀93以及供给泵95流向洗涤剂供给路96，冲走液体洗涤剂。水与液体洗涤 剂混合成为清洗水。如图2的粗线箭头所示，清洗水穿过清洗水供给路98流入贮留箱60内。当副阀83被打开后经过了预先规定的供给时间时，副阀83被关闭。Next, the first three-way valve 93 is switched to a state in which the auxiliary water supply passage 94 and the supply pump 95 are communicated, and the auxiliary valve 83 is opened. As shown by the solid arrow in FIG. 2, the water from the faucet passes through the auxiliary water supply path 94, the first three-way valve 93, and the supply pump 95 to flow to the detergent supply path 96 to flush away the liquid detergent. The water is mixed with the liquid detergent to form washing water. As shown by the thick arrow in FIG. 2, the washing water passes through the washing water supply path 98 and flows into the storage tank 60. When the predetermined supply time elapses after the auxiliary valve 83 is opened, the auxiliary valve 83 is closed.
如此一来，规定的量和洗涤剂浓度的清洗水蓄于贮留箱60内。本实施方式中，蓄于贮留箱60的清洗水的量为能替换贮水桶210内的清洗水进行两次清洗运转的量。需要说明的是，蓄于贮留箱60的清洗水的量也可以是能进行三次以上的清洗运转的量。In this way, washing water of a predetermined amount and detergent concentration is stored in the storage tank 60. In the present embodiment, the amount of washing water stored in the storage tank 60 is an amount that can replace the washing water in the water storage bucket 210 to perform two washing operations. It should be noted that the amount of washing water stored in the storage tank 60 may be an amount that enables three or more washing operations.
接着，供给阀400被打开。贮留箱60内的清洗水穿过供给喷嘴500从放出口501放出至贮水桶210内。清洗水蓄于贮水桶210内，贮水桶210内的水位上升。如图9的单点划线所示，当贮水桶210内的水位上升至放出口501的高度而放出口501被清洗水堵住时，贮留箱60内的气压和外部的气压相平衡。由此，在供给阀400打开的状态下，来自贮留箱60的供水停止。Next, the supply valve 400 is opened. The washing water in the storage tank 60 passes through the supply nozzle 500 and is discharged from the discharge port 501 into the water storage bucket 210. The washing water is stored in the water storage bucket 210, and the water level in the water storage bucket 210 rises. As shown by the one-dot chain line in FIG. 9, when the water level in the water storage bucket 210 rises to the height of the discharge port 501 and the discharge port 501 is blocked by washing water, the air pressure in the storage tank 60 is balanced with the external air pressure. Thus, in a state where the supply valve 400 is opened, the water supply from the storage tank 60 is stopped.
当贮水桶210内蓄有清洗水时，用户将被清洗物的污垢附着部分，例如衬衫的衣领部分从超声波清洗部100的正面方向放置于贮水桶210上即贮水桶210与超声波发生体110的振动变幅杆112之间。When washing water is stored in the water storage bucket 210, the user places the dirt attached part of the object to be cleaned, such as the collar part of the shirt, on the water storage bucket 210 from the front of the ultrasonic cleaning unit 100, that is, the water storage bucket 210 and the ultrasonic generator 110 Between the vibration horn 112.
超声波清洗部100中，盖130的引导部132的位置与超声波发生体110的振动变幅杆112的顶端部的位置在前后方向上一致。因此，引导部132成为标记，用户容易掌握振动变幅杆112的顶端部的位置。In the ultrasonic cleaning unit 100, the position of the guide portion 132 of the cover 130 and the position of the tip portion of the vibration horn 112 of the ultrasonic generator 110 coincide in the front-rear direction. Therefore, the guide portion 132 becomes a mark, and the user can easily grasp the position of the tip portion of the vibration horn 112.
用户将衣领、袖口等污垢附着部分抵在引导部132的引导面133上，沿着引导面133向下方且向后方移动，到达振动变幅杆112的顶端面112a的位置。此时，引导部132的下端延伸至盖主体131的下端的下方，将从盖主体131露出的振动变幅杆112的顶端部的正面覆盖。因此，被引导部132引导的污垢附着部分不容易被振动变幅杆112的顶端部的角部勾住，不容易发生损伤等。此外，通过引导部132的引导，污垢附着部分被定位至几乎与振动变幅杆112的顶端面112a接触的合适的高度位置，不会与振动变幅杆112的顶端面112a离得太远。The user pushes the dirt-adhering parts such as collars and cuffs to the guide surface 133 of the guide portion 132, moves downward and backward along the guide surface 133, and reaches the position of the tip surface 112a of the vibrating horn 112. At this time, the lower end of the guide portion 132 extends below the lower end of the cover main body 131 to cover the front surface of the tip portion of the vibrating horn 112 exposed from the cover main body 131. Therefore, the dirt adhered portion guided by the guide portion 132 is not easily caught by the corner of the tip portion of the vibration horn 112, and damage or the like is not likely to occur. In addition, guided by the guide portion 132, the dirt adhered part is positioned to a suitable height position almost in contact with the top surface 112a of the vibrating horn 112, and not too far away from the top surface 112a of the vibrating horn 112.
被清洗物的污垢附着部分被浸泡至蓄于贮水桶210内的清洗水中，浸透到被清洗物的内部的清洗水渗出表面。呈现如下状态：在被清洗物的表面形成有 薄薄的水层，振动变幅杆112与该水层接触。需要说明的是，当被清洗物吸水而使得贮水桶210内的水位下降，供给喷嘴500的放出口501不再被清洗水堵住时，从贮留箱60向贮水桶210内补给清洗水，直到放出口501再次被清洗水堵住。由此，贮水桶210内的水位即水量维持在适当的状态。The dirt adhered part of the object to be cleaned is immersed in the washing water stored in the water storage bucket 210, and the cleaning water that has penetrated into the inside of the object to be cleaned seeps out of the surface. It presents a state in which a thin water layer is formed on the surface of the object to be cleaned, and the vibrating horn 112 is in contact with the water layer. It should be noted that when the object to be cleaned absorbs water and the water level in the water storage bucket 210 drops, and the discharge port 501 of the supply nozzle 500 is no longer blocked by cleaning water, the cleaning water is supplied from the storage tank 60 to the water storage bucket 210. Until the discharge port 501 is blocked by the washing water again. As a result, the water level in the water storage bucket 210, that is, the amount of water, is maintained in an appropriate state.
在供给阀400被打开后到经过规定的待机时间为止，不对超声波振子111进行通电，超声波发生体110处于待机的状态。在此期间，贮水桶210中蓄有清洗水，蓄有清洗水的贮水桶210中放置有被清洗物。当经过待机时间时，对超声波振子111进行通电，超声波发生体110工作。After the supply valve 400 is opened, until a predetermined standby time elapses, the ultrasonic vibrator 111 is not energized, and the ultrasonic generator 110 is in a standby state. During this period, washing water is stored in the water storage bucket 210, and the washing object is placed in the water storage bucket 210 which stores the washing water. When the standby time elapses, the ultrasonic vibrator 111 is energized, and the ultrasonic generator 110 operates.
图11的(a)至(c)是用于说明由超声波清洗装置50实现的被清洗物的去污的图。(A) to (c) of FIG. 11 are diagrams for explaining the decontamination of the object to be cleaned by the ultrasonic cleaning device 50.
当超声波发生体110工作时，从振动变幅杆112的顶端产生超声波，超声波振动经由振动变幅杆112周围的清洗水传递至被清洗物内部的清洗水。如图11的(a)所示，在被清洗物的内部，通过超声波振动的作用交替地产生减压和加压，在压力变低的部分产生真空的空腔。即，呈被清洗物的污垢的部分存在许多空腔的状态。接着，如图11的(b)所示，当空腔部分的压力变高，空腔被该压力破坏而崩溃时，会对被清洗物的污垢部分产生冲击波。通过该冲击波，污垢从被清洗物分离。如图11的(c)所示，来自振动变幅杆112的超声波振动会产生从被清洗物的内部前往贮水桶210内的水流，通过该水流，从被清洗物分离出的污垢被排出至贮水桶210内。在贮水桶210中，通过上述的水流产生对流，因此，污垢容易从被清洗物中剥离。进而，通过清洗水中所含的洗涤剂的作用也容易使污垢从被清洗物剥离，而且，污垢不容易再次附着于被清洗物。如此一来，污垢从被清洗物中去除。如上所述，被清洗物以污垢附着部分不会离超声波发生体110的振动变幅杆112的顶端面112a太远的方式放置于贮水桶210。由此，来自振动变幅杆112的超声波振动有效地作用于污垢附着部分，容易去污。When the ultrasonic generator 110 operates, ultrasonic waves are generated from the tip of the vibrating horn 112, and the ultrasonic vibration is transmitted to the washing water inside the object to be cleaned via the washing water around the vibrating horn 112. As shown in (a) of FIG. 11, in the interior of the object to be cleaned, decompression and pressurization are alternately generated by the action of ultrasonic vibration, and a vacuum cavity is generated in a portion where the pressure becomes lower. That is, there are many cavities in the dirty part of the object to be cleaned. Next, as shown in FIG. 11(b), when the pressure of the cavity portion becomes high and the cavity is broken by the pressure and collapses, shock waves are generated on the dirt portion of the object to be cleaned. This shock wave separates dirt from the object to be cleaned. As shown in Figure 11(c), the ultrasonic vibration from the vibrating horn 112 generates a water flow from the inside of the object to be cleaned to the inside of the water storage bucket 210, and the dirt separated from the object to be cleaned is discharged to In the water storage bucket 210. In the water storage bucket 210, convection is generated by the above-mentioned water flow, and therefore, dirt is easily peeled off from the object to be cleaned. Furthermore, the action of the detergent contained in the washing water is also easy to peel off the dirt from the object to be cleaned, and the dirt does not easily adhere to the object to be cleaned again. In this way, the dirt is removed from the objects to be cleaned. As described above, the object to be cleaned is placed in the water tank 210 in such a way that the dirt attached part is not too far from the top end surface 112a of the vibration horn 112 of the ultrasonic generator 110. As a result, the ultrasonic vibration from the vibrating horn 112 effectively acts on the dirt adhering part, making it easy to decontaminate.
当被清洗物的清洗完成时，用户进行规定的结束操作以结束清洗运转。超声波发生体110的工作停止并且供给阀400关闭，清洗运转结束。When the cleaning of the object to be cleaned is completed, the user performs a prescribed end operation to end the cleaning operation. The operation of the ultrasonic generator 110 is stopped and the supply valve 400 is closed, and the cleaning operation ends.
在不继续进行新的清洗运转的情况下，如图3的(a)所示，用户将超声波清洗装置50向收纳部17收纳，使超声波清洗部100和贮水部200向待机位置 移动。如图8所示，当贮水部200移动至待机位置时，在阀切换机构230中，阀可动构件240的后板部244与排水承接部70的后表面的两个肋74抵接，被这些肋74推压，克服弹簧260的施加力相对于贮水部200向前方移动。与阀可动构件240的后板部244连结的阀体220相对于贮水桶210的排水口211向前方即敞开方向移动，打开排水口211。由此，蓄于贮水桶210的清洗水通过排水口211排出。此时，清洗水穿过排水口211的内壁面与阀体220的上下的平坦面223之间的间隙、阀体220的左右开口224以及孔222。从排水口211排出的清洗水被排水承接部70承接，从排出孔71排出。从排出孔71排出的清洗水流过排水管72、溢水管26以及排水软管41向机外排出。When the new cleaning operation is not continued, as shown in FIG. 3(a), the user stores the ultrasonic cleaning device 50 in the storage unit 17 and moves the ultrasonic cleaning unit 100 and the water storage unit 200 to the standby position. As shown in FIG. 8, when the water storage unit 200 moves to the standby position, in the valve switching mechanism 230, the rear plate portion 244 of the valve movable member 240 abuts on the two ribs 74 on the rear surface of the drain receiving portion 70, and It is pushed by these ribs 74 and moves forward with respect to the water storage unit 200 against the biasing force of the spring 260. The valve body 220 connected to the rear plate portion 244 of the valve movable member 240 moves forward, that is, in the opening direction, with respect to the drain port 211 of the water tank 210 to open the drain port 211. Thus, the washing water stored in the water storage tub 210 is discharged through the drain port 211. At this time, the washing water passes through the gap between the inner wall surface of the drain port 211 and the upper and lower flat surfaces 223 of the valve body 220, the left and right openings 224 and the holes 222 of the valve body 220. The washing water drained from the drain port 211 is received by the drain receiver 70 and drained from the drain hole 71. The washing water discharged from the discharge hole 71 flows through the drain pipe 72, the overflow pipe 26, and the drain hose 41 to be discharged to the outside of the machine.
用户有时会想更换贮水桶210的清洗水进行第二次清洗运转。这种情况下，虽然用户能将超声波清洗装置50收纳于收纳部17并使贮水部200移动至待机位置从而从贮水桶210排出清洗水，但是这样操作比较麻烦。The user sometimes wants to replace the washing water in the water storage bucket 210 for the second washing operation. In this case, although the user can store the ultrasonic cleaning device 50 in the storage unit 17 and move the water storage unit 200 to the standby position to discharge the washing water from the water storage bucket 210, this operation is troublesome.
因此，在本实施方式中，用户使贮水部200维持在运转位置而无需移动超声波清洗装置50，就能从贮水桶210排出清洗水。Therefore, in this embodiment, the user can drain the washing water from the water storage bucket 210 without moving the ultrasonic cleaning device 50 while maintaining the water storage unit 200 in the operating position.
图12是表示操作部250在超声波清洗装置50被从收纳部17拉出的状态下被移动操作时的样子的、上面板12的后部的侧剖图。需要说明的是，在图12中，为了便于说明，超声波清洗装置50中，比配置有操作部250的贮水部200的操作窗204靠后方处以剖面的方式画出。FIG. 12 is a side cross-sectional view of the rear part of the upper panel 12 showing how the operation unit 250 is moved and operated in a state where the ultrasonic cleaning device 50 is pulled out from the storage unit 17. It should be noted that, in FIG. 12, for convenience of description, the ultrasonic cleaning device 50 is drawn in a cross section behind the operation window 204 of the water storage unit 200 where the operation unit 250 is arranged.
在超声波清洗部100和贮水部200位于运转位置的状态下，如图12的粗线箭头所示，用户进行使操作部250向前方移动的移动操作。由此，在阀切换机构230中，与贮水部200移动至待机位置时一样，阀可动构件240相对于贮水部200向前方向移动。由此，阀体220相对于贮水桶210的排水口211向敞开方向移动，排水口211敞开。由此，蓄于贮水桶210的清洗水通过排水口211排出，被排水承接部70承接。然后，清洗水经由排水管72、溢水管26以及排水软管41向机外排出。In a state where the ultrasonic cleaning unit 100 and the water storage unit 200 are in the operating positions, as shown by the thick arrow in FIG. 12, the user performs a movement operation to move the operation unit 250 forward. Thereby, in the valve switching mechanism 230, the valve movable member 240 moves in the forward direction with respect to the water storage unit 200 in the same manner as when the water storage unit 200 moves to the standby position. Thereby, the valve body 220 moves in the opening direction with respect to the drain port 211 of the water storage tub 210, and the drain port 211 is opened. As a result, the washing water stored in the water storage bucket 210 is discharged through the drain port 211 and is received by the drain receiving portion 70. Then, the washing water is discharged to the outside of the machine through the drain pipe 72, the overflow pipe 26, and the drain hose 41.
用户进行用于继续清洗运转的规定的继续操作。第二次的清洗运转开始。需要说明的是，在该清洗运转中，由于贮留箱60内残留有清洗水，因此打开供给阀400从贮留箱60向贮水桶210供给清洗水而不进行向贮留箱60内的清洗水的供给。需要说明的是，在本实施方式中，如果进行两次清洗运转的话，贮 留箱60内的清洗水就用完了，因此只接受一次继续操作。The user performs a predetermined continuing operation for continuing the cleaning operation. The second cleaning operation starts. It should be noted that during this washing operation, since washing water remains in the storage tank 60, the supply valve 400 is opened to supply washing water from the storage tank 60 to the water storage bucket 210 without washing the storage tank 60. Water supply. It should be noted that, in this embodiment, if two washing operations are performed, the washing water in the storage tank 60 is used up, so only one continuous operation is accepted.
在超声波清洗部100中，在反复进行清洗运转的过程中，污垢从盖130的开口进入盖130内，在盖130的内部，污垢能附着于超声波发生体110的振动变幅杆112。在本实施方式中，由于盖130可拆卸于壳体120，因此用户能将盖130从壳体120卸下来进行振动变幅杆112的清理。In the ultrasonic cleaning unit 100, during the repeated cleaning operation, dirt enters the cover 130 from the opening of the cover 130, and the dirt can adhere to the vibration horn 112 of the ultrasonic generator 110 inside the cover 130. In this embodiment, since the cover 130 is detachable from the housing 120, the user can remove the cover 130 from the housing 120 to clean the vibrating horn 112.
此外，在反复进行清洗运转的过程中，贮水桶210可能会被弄脏。在本实施方式中，由于贮水部200可拆装于主体部300，因此用户能将贮水部200从主体部300卸下来进行贮水桶210的清洗。In addition, during repeated washing operations, the water storage bucket 210 may be soiled. In this embodiment, since the water storage unit 200 is detachable from the main body unit 300, the user can remove the water storage unit 200 from the main body unit 300 to clean the water storage bucket 210.
＜实施方式的效果＞<Effects of the embodiment>
以上，根据本实施方式，设置有对贮水桶210的排水口211进行开闭的阀体220和阀切换机构230，通过阀切换机构230进行阀体220切换，使得在超声波清洗部100和贮水部200即超声波发生体110和贮水桶210位于运转位置时呈阀体220关闭的状态，在超声波清洗部100和贮水部200位于待机位置时呈阀体220打开的状态。由此能实现：在超声波清洗装置50处于能进行清洗运转的状态时无法从贮水桶210进行排水，在超声波清洗装置50处于无法进行清洗运转的状态时能从贮水桶210进行排水。As described above, according to this embodiment, the valve body 220 that opens and closes the drain port 211 of the water storage bucket 210 and the valve switching mechanism 230 are provided. The valve body 220 is switched by the valve switching mechanism 230, so that the ultrasonic cleaning unit 100 and the water storage The valve body 220 is closed when the ultrasonic generator 110 and the water storage bucket 210 are in the operating position, and the valve 220 is opened when the ultrasonic cleaning part 100 and the water storage 200 are in the standby position. As a result, it can be achieved that water cannot be drained from the water storage bucket 210 when the ultrasonic cleaning device 50 is in a state where the cleaning operation can be performed, and water can be drained from the water storage tub 210 when the ultrasonic cleaning device 50 is in a state where the cleaning operation cannot be performed.
此外，阀切换机构230中包括操作部250，当在超声波发生体110和贮水桶210位于运转位置时进行了由操作部250实现的开操作时，通过阀切换机构230进行阀体220从闭状态向开状态的切换。由此，即使在超声波发生体110和贮水桶210位于运转位置的情况下，也能在需要更换贮水桶210的水等时从贮水桶210排出清洗水而无需使超声波发生体110和贮水桶210返回待机位置。In addition, the valve switching mechanism 230 includes an operating portion 250. When the opening operation by the operating portion 250 is performed when the ultrasonic generator 110 and the water storage tank 210 are in the operating position, the valve body 220 is switched from the closed state by the valve switching mechanism 230. Switch to the on state. Thus, even when the ultrasonic generator 110 and the water storage bucket 210 are in the operating position, the washing water can be discharged from the water storage bucket 210 when the water in the water storage bucket 210 needs to be replaced, etc., without the need for the ultrasonic generator 110 and the water storage bucket 210. Return to the standby position.
如此一来，根据本实施方式，能从贮水桶210良好地排水，能提高对用户的便利性。In this way, according to the present embodiment, the water can be drained from the water storage tub 210 well, and the convenience for the user can be improved.
进而，根据本实施方式，采用了供从排水承接部70排出的清洗水流过的排水管72连接于将从溢水口20b流出的溢水导向排水软管41的溢水管26的结构，因此，与排水管72连接于排水软管41的结构相比，能缩短排水管72。由此，在例如脱水时外桶20振动时，排水管72不容易与箱体10接触，不容易产生排水管72的破损等。Furthermore, according to this embodiment, the drain pipe 72 through which the washing water discharged from the drain receiving portion 70 flows is connected to the overflow pipe 26 that guides the overflow water from the overflow port 20b to the drain hose 41. Compared with the structure in which the pipe 72 is connected to the drain hose 41, the drain pipe 72 can be shortened. Therefore, when the outer tub 20 vibrates during dehydration, for example, the drain pipe 72 is not likely to come into contact with the tank body 10, and the drain pipe 72 is not easily damaged or the like.
进而，根据本实施方式，采用了从自动投入机构90供给的清洗水蓄于贮水容量比贮水桶210大的贮留箱60并从该贮留箱60供给至贮水桶210的结构，因此，无需在每次更换贮水桶210内的清洗水时生成清洗水，提高了对用户的便利性。Furthermore, according to the present embodiment, the washing water supplied from the automatic input mechanism 90 is stored in the storage tank 60 having a water storage capacity larger than that of the water storage bucket 210 and is supplied from the storage tank 60 to the water storage bucket 210. Therefore, There is no need to generate washing water every time the washing water in the water storage bucket 210 is replaced, which improves the convenience for users.
以上，对本发明的实施方式进行了说明，但本发明不受上述实施方式的任何限制，此外，本发明的实施方式除了上述以外还可以进行各种变形。As mentioned above, the embodiment of the present invention has been described, but the present invention is not limited to the above-mentioned embodiment at all. In addition, the embodiment of the present invention can be variously modified in addition to the above.
例如，在上述实施方式中采用了如下结构，阀切换机构230包括：弹簧260，向排水口211被闭塞的闭塞方向对阀体220施力；以及阀可动构件240，与阀体220和操作部250连结，在超声波发生体110和贮水桶210从运转位置移动至待机位置时，阀可动构件240的后板部244与设置于排水承接部70的肋74抵接，被肋74推压而使阀体220向排水口211被敞开的敞开方向移动，并且在对操作部250进行了移动操作时，阀可动构件240与操作部250一起移动使阀体220向敞开方向移动。For example, in the above-mentioned embodiment, the following structure is adopted. The valve switching mechanism 230 includes: a spring 260 for urging the valve body 220 in the blocking direction in which the drain port 211 is blocked; and a valve movable member 240, which interacts with the valve body 220 and operates When the ultrasonic generator 110 and the water storage bucket 210 are moved from the operating position to the standby position, the rear plate 244 of the valve movable member 240 abuts against the rib 74 provided in the drain receiving portion 70, and is pressed by the rib 74 When the valve body 220 is moved in the opening direction where the drain port 211 is opened, and when the operation portion 250 is moved, the valve movable member 240 moves together with the operation portion 250 to move the valve body 220 in the opening direction.
但是，只要能以在超声波发生体110和贮水桶210位于运转位置时阀体220呈闭状态且在超声波发生体110和贮水桶210位于待机位置时阀体220呈开状态的方式对阀体220进行切换，并且能在超声波发生体110和贮水桶210位于运转位置时对操作部250进行开操作后使阀体220从闭状态切换至开状态，阀切换机构230也可以采用上述以外的机构。However, as long as the valve body 220 is closed when the ultrasonic generator 110 and the water storage bucket 210 are in the operating position, and the valve body 220 is opened when the ultrasonic generator 110 and the water storage bucket 210 are in the standby position, the valve body 220 can be opened. The valve body 220 can be switched from the closed state to the open state after the operating unit 250 is opened when the ultrasonic generator 110 and the water storage bucket 210 are in the operating position. The valve switching mechanism 230 may also adopt a mechanism other than the above.
此外，在上述实施方式中，排水管72与溢水管26连接。但是，也可以是，排水管72与溢水承接部25连接。但是，在考虑到要使从排水管72排出的清洗水不会从溢水口20b进入外桶20内的情况下，理想的是，排水管72与远离溢水口20b的溢水管26连接。In addition, in the above-described embodiment, the drain pipe 72 is connected to the overflow pipe 26. However, the drain pipe 72 may be connected to the overflow water receiving portion 25. However, considering that the washing water discharged from the drain pipe 72 does not enter the outer tub 20 from the overflow port 20b, it is desirable that the drain pipe 72 be connected to the overflow pipe 26 away from the overflow port 20b.
进而，在上述实施方式中，供给清洗水即含有洗涤剂的水的自动投入机构90与贮留箱60连接。但是，只要最终能向贮留箱60中蓄留清洗水即可，因此可以采用如下结构：向贮留箱60至少进行供水即可，例如在贮留箱60设置有洗涤剂的投入口，只从供水单元80向预先投入了洗涤剂的贮留箱60供水。Furthermore, in the aforementioned embodiment, the automatic input mechanism 90 for supplying washing water, that is, water containing detergent, is connected to the storage tank 60. However, as long as the washing water can finally be stored in the storage tank 60, the following structure can be adopted: at least water is supplied to the storage tank 60. For example, a detergent input port is provided in the storage tank 60. Water is supplied from the water supply unit 80 to the storage tank 60 into which detergent has been put in advance.
进而，在上述实施方式中，超声波清洗装置50设置于全自动洗衣机1。但是，也可以将超声波清洗装置50设置于全自动洗衣机1以外的洗衣机，例如滚 筒式洗衣机。此外，也可以将超声波清洗装置50设置于例如具有烘干功能的全自动洗干一体机、滚筒式洗干一体机。在滚筒式洗衣机和滚筒式洗干一体机中，滚筒作为内桶配置在外桶内。进而，超声波清洗装置50也可以配置于洗脸池等洗衣机之外的装置中准备的配置部。Furthermore, in the above-mentioned embodiment, the ultrasonic cleaning device 50 is provided in the fully automatic washing machine 1. However, the ultrasonic cleaning device 50 may be installed in a washing machine other than the fully automatic washing machine 1, such as a drum type washing machine. In addition, the ultrasonic cleaning device 50 may be installed in, for example, a fully automatic washer-dryer with a drying function or a drum-type washer-dryer. In the drum-type washing machine and the drum-type washer-dryer, the drum is disposed in the outer tub as an inner tub. Furthermore, the ultrasonic cleaning apparatus 50 may be arrange|positioned in the arrangement part prepared in the apparatus other than a washing machine, such as a washbasin.
此外，本发明的实施方式能在技术方案所示的技术思想的范围内适当地进行各种变形。In addition, the embodiment of the present invention can be appropriately modified in various ways within the scope of the technical idea shown in the technical solution.
