本发明涉及洗衣机。The present invention relates to washing machines.
背景技术Background technique
专利文献1中记载了一种在上面板中洗涤物投放口的周围，例如在投放口的前侧配置有超声波清洗装置的洗衣机。超声波清洗装置具备可蓄水的贮水桶和具有位于贮水桶正上方的超声波发生体的超声波发生单元。在蓄有水的贮水桶内放置被清洗物的污垢附着部分，开始清洗运转。由超声发生体产生的超声波能量作用于浸透了水的污垢附着部分来剥离污垢。 Patent Document 1 describes a washing machine in which an ultrasonic cleaning device is arranged around the laundry inlet on the upper panel, for example, in front of the inlet. The ultrasonic cleaning apparatus includes a water storage tank capable of storing water, and an ultrasonic generating unit having an ultrasonic generating body located directly above the water storage tank. The dirt adhering part of the object to be cleaned is placed in the water storage tank in which the water is stored, and the cleaning operation is started. The ultrasonic energy generated by the ultrasonic generator acts on the water-saturated dirt adhering portion to peel off the dirt.
洗衣机具备向贮水桶供水的供水单元。供水单元包括与水龙头相连的供水阀，当供水阀打开时，向贮水桶供水。The washing machine includes a water supply unit that supplies water to the water storage tub. The water supply unit includes a water supply valve connected with a water tap, and when the water supply valve is opened, water is supplied to the water storage bucket.
在上述的洗衣机中，为了进一步提高由超声波清洗装置实现的被清洗物的清洗效果，考虑将含有洗涤剂的水作为清洗水蓄留于贮水桶内。在这样的情况下，可以采用将洗涤剂和水供给至与贮水桶分开设置的贮留部内来生成清洗水并向贮水桶供给所生成的清洗水这样的结构。In the above-mentioned washing machine, in order to further improve the cleaning effect of the object to be cleaned by the ultrasonic cleaning device, it is considered that water containing detergent is stored in the water storage tub as cleaning water. In such a case, a configuration may be adopted in which detergent and water are supplied into a reservoir provided separately from the water storage tank to generate washing water, and the generated washing water is supplied to the water storage tank.
在采用这样的结构的情况下，要求向贮留部供水的供水量稳定，以减少清洗水中的洗涤剂浓度的不均。In the case of adopting such a structure, it is required to stabilize the water supply amount of the water supply to the storage part so as to reduce the unevenness of the detergent concentration in the washing water.

发明内容SUMMARY OF THE INVENTION
发明所要解决的问题The problem to be solved by the invention
因此，本发明的目的在于提供一种能通过高精度地检测贮留部内的水位来使向贮留部供水的供水量稳定的洗衣机。Therefore, the objective of this invention is to provide the washing machine which can stabilize the water supply amount of the water supply to a storage part by detecting the water level in a storage part with high precision.
用于解决问题的方案solution to the problem
本发明的主要方案的洗衣机具备：超声波发生体，产生超声波；贮水桶，位于所述超声波发生体的下方，蓄留供被清洗物浸泡的水；贮留部，蓄留要向所述贮水桶供给的含有洗涤剂的水；供给部，向所述贮留部内至少供给水；以及水位检测部，检测所述贮留部内的水位。其中，所述水位检测部包括从所述贮留部的顶面部向下方延伸的一对电极端子，所述一对电极端子中，一方的电极端子比另一方的电极端子长。The washing machine of the main scheme of the present invention is provided with: an ultrasonic generator, which generates ultrasonic waves; a water storage bucket, which is located below the ultrasonic generator and stores the water for soaking the objects to be cleaned; The supplied detergent-containing water; a supply unit that supplies at least water into the storage unit; and a water level detection unit that detects the water level in the storage unit. The water level detection unit includes a pair of electrode terminals extending downward from the top surface of the storage unit, and one electrode terminal of the pair of electrode terminals is longer than the other electrode terminal.
根据本方案的洗衣机，能使一方的电极端子的前端的位置比另一方的电极端子的前端的位置低，因此能使一方的电极端子从贮留部内的水位低于由水位检测部检测出的水位的状态就开始接触贮留部内的水。由此，即使水面发生了起伏，一方的电极端子与水的接触也稳定。因此，水位的检测时刻不易发生波动，能高精度地检测贮留部内的水位。According to the washing machine of the present aspect, the position of the leading end of one electrode terminal can be made lower than the position of the leading end of the other electrode terminal, so that the water level of the one electrode terminal from the storage portion can be made lower than the water level detected by the water level detecting portion. The state of the water level starts to contact the water in the storage part. Thereby, even if the water surface fluctuates, the contact between one of the electrode terminals and the water is stabilized. Therefore, the detection timing of the water level is less likely to fluctuate, and the water level in the reservoir can be detected with high accuracy.
在本方案的洗衣机中，可以是，从上方观察时，所述贮留部在第一方向上的尺寸比与该第一方向垂直的第二方向上的尺寸大。在该情况下，所述一对电极端子可以在所述第一方向上排列。In the washing machine of this aspect, when viewed from above, the size of the storage portion in the first direction may be larger than the size in the second direction perpendicular to the first direction. In this case, the pair of electrode terminals may be arranged in the first direction.
根据上述的结构，能增大一对电极端子的间隔，因此即使在向贮留部供水时水面的一部分发生了由洗涤剂引起的起泡，双方的电极端子也不易与该泡接触。由此，不易发生因与泡的接触而导致一对电极端子变为导通状态从而对水位作出误检测这样的情况，能提高水位的检测精度。According to the above configuration, since the distance between the pair of electrode terminals can be increased, even if foaming due to the detergent occurs in part of the water surface when water is supplied to the reservoir, both electrode terminals are less likely to come into contact with the foam. Thereby, it becomes difficult to generate|occur|produce the situation where a pair of electrode terminal becomes a conduction state by contact with a bubble, and a water level is erroneously detected, and the detection precision of a water level can be improved.
在本方案的洗衣机中，所述贮留部可以采用包括供来自所述供给部的水流入的流入口的结构。在该情况下，可以是，所述流入口在所述一对电极端子排列的方向上相对于所述一方的电极端子位于与所述另一方的电极端子相反的一侧。In the washing machine of this aspect, the storage part may have a structure including an inflow port into which the water from the supply part flows. In this case, the inflow port may be located on the opposite side to the other electrode terminal with respect to the one electrode terminal in the direction in which the pair of electrode terminals are arranged.
根据上述的结构，在水从流入口流入时，一方的电极端子成为水流的上游侧，另一方的电极端子成为水流的下游侧。下游侧比上游侧容易平息起伏，因此另一方的电极端子与水的接触容易变得稳定。因此，水位的检测时刻更不易 发生波动，能更高精度地检测贮留部内的水位。According to the above configuration, when water flows in from the inflow port, one electrode terminal becomes the upstream side of the water flow, and the other electrode terminal becomes the downstream side of the water flow. The downstream side is easier to calm down than the upstream side, so the contact between the other electrode terminal and the water is more likely to be stabilized. Therefore, the detection timing of the water level is less likely to fluctuate, and the water level in the reservoir can be detected with higher accuracy.
在本方案的洗衣机中，所述贮留部可以采用包括来自所述供给部的水所流入的第一箱(tank)和与该第一箱在彼此的下部连接的第二箱的结构。在该情况下，所述一对电极端子可以配置于所述第二箱。In the washing machine of this aspect, the storage part may have a structure including a first tank into which the water from the supply part flows, and a second tank connected to the first tank at the lower part of each other. In this case, the pair of electrode terminals may be arranged in the second box.
根据上述的结构，在第二箱中，与来自供给部的水直接流入的第一箱相比水面的起伏变少。根据上述的结构，一对电极端子配置于第二箱，因此在水位的检测时刻更不易发生波动，能更高精度地检测贮留部内的水位。According to the above-mentioned configuration, in the second tank, the fluctuation of the water surface is less than that in the first tank into which the water from the supply unit flows directly. According to the above-mentioned configuration, since the pair of electrode terminals are arranged in the second tank, fluctuations are less likely to occur at the detection timing of the water level, and the water level in the reservoir can be detected with higher accuracy.
在采用上述的结构的情况下，进而，所述贮留部可以采用隔着供给阀被分为所述第一箱和所述第二箱的结构。在该情况下，所述供给阀可以包括两个入口。进而，可以将来自所述第一箱的水的流出口和来自所述第二箱的水的流出口与所述两个入口连接。In the case of adopting the above-mentioned configuration, further, the storage portion may be configured to be divided into the first tank and the second tank with a supply valve interposed therebetween. In this case, the supply valve may comprise two inlets. Further, the outflow port of the water from the first tank and the outflow port of the water from the second tank may be connected to the two inlets.
当采用这样的结构时，能使含有洗涤剂的水分别从第一箱和第二箱经过供给阀流出，因此能从贮留部将含有洗涤剂的水顺畅地供给至贮水桶。此外，能使从流入口流入至第一箱内的水经过供给阀流入第二箱而蓄于第二箱内。According to such a structure, since the water containing detergent can flow out from the 1st tank and the 2nd tank respectively through a supply valve, the water containing detergent can be smoothly supplied to a water tank from a storage part. Moreover, the water which flowed into the 1st tank from an inflow port can flow into a 2nd tank through a supply valve, and can be stored in a 2nd tank.

The detection circuit 800 is connected to the control unit 16 . During water level detection, a voltage is applied between the first electrode terminal 710 and the second electrode terminal 720 . The detection circuit 800 includes a rectangular wave generating circuit, and outputs a pulse-shaped detection signal to the control unit 16 when the first electrode terminal 710 and the second electrode terminal 720 are brought into a conductive state by contacting the cleaning water, and according to the flow through the first electrode The magnitude of the current between the terminal 710 and the second electrode terminal 720 changes the pulse width of the detection signal.
在第二箱62的内部以从底面部向上方突出的方式设有圆筒状的溢水口部69。溢水口部69的前端的开口69a位于基于水位检测部700的检测比蓄于贮留箱60的规定水位L2高的溢水水位的位置，当清洗水的水位超过溢水水位时，清洗水流向溢水口部69。溢水口部69的下端的出口与供给喷嘴500连接，从溢水口部69排出的清洗水被导向供给喷嘴500。A cylindrical overflow portion 69 is provided inside the second tank 62 so as to protrude upward from the bottom surface. The opening 69a at the front end of the overflow port portion 69 is located at a position of the overflow water level higher than the predetermined water level L2 stored in the storage tank 60 based on the detection of the water level detection portion 700. When the water level of the washing water exceeds the overflow water level, the washing water flows to the overflow port. Section 69. The outlet at the lower end of the overflow port portion 69 is connected to the supply nozzle 500 , and the washing water discharged from the overflow port portion 69 is guided to 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，其前端部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 has a front end portion 500a bent downward. The discharge port 501 is formed in the lower surface of the front-end|tip part 500a.

A drain pipe 72 is connected to a connection pipe 73 extending rightward from the discharge hole 71 .
全自动洗衣机1中进行各种运转模式的洗涤运转。在洗涤运转中，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 operation in various operation modes. In the washing operation, a washing process, an intermediate dehydration process, a rinsing process, and a final dehydration process are performed in sequence.
在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。在清洗过程中，通过产生的水流和水中所含的洗涤剂，洗涤物被清洗。在漂洗过程中，通过产生的水流，洗涤物被漂洗。During the cleaning process and the rinsing process, the pulsator 24 rotates rightward and leftward in a state where water is stored in the washing and dewatering tub 22 . Through the rotation of the pulsator 24, a water flow is generated in the washing and dewatering 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.
在中间脱水过程和最终脱水过程中，洗涤脱水桶22和波轮24成为一体高速旋转。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 dehydrating tub 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 .
在进行清洗过程中的供水时，由自动投放机构90向洗涤脱水桶22内自动投放液体洗涤剂。此时，首先，第一三通阀93被切换至使供给管92与供给泵95连通的状态。此外，第二三通阀97被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抽吸作用被排出。排出的液体洗涤剂如图2的虚线箭头所示经过供给管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工作预定的时间，由此，预定量的液体洗涤剂蓄于上游侧供给路96b。During the water supply in the cleaning process, the liquid detergent is automatically injected into the washing and dewatering tub 22 by the automatic injection 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 with each other. In addition, the second three-way valve 97 is switched to a state in which the upstream supply passage 96b and the downstream supply passage 96c communicate with each other. When the supply pump 95 operates, the liquid detergent in the detergent box 91 is discharged by suction. 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 indicated by the dotted arrow in FIG. 2 , and is stored in the upstream side supply path 96 b of the detergent supply path 96 . The supply pump 95 operates for a predetermined time, whereby a predetermined amount of the liquid detergent is stored in the upstream supply passage 96b.
接着，第一三通阀93被切换至使副供水路94与供给泵95连通的状态，主 阀82和副阀83打开。来自水龙头的水流过主供水路84从注水口84a向洗涤脱水桶22内被放出。同时，如图2的实线箭头所示，来自水龙头的水经过副供水路94、第一三通阀93以及供给泵95流向洗涤剂供给路96而冲走液体洗涤剂。被水冲走的液体洗涤剂如图2的点划线箭头所示与水一起从洗涤剂供给路96的供给口96a被投放至洗涤脱水桶22内。当洗涤脱水桶22内的水位到达规定的清洗水位时，主阀82和副阀83关闭，供水结束。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 communicate with each other, and the main valve 82 and the auxiliary valve 83 are opened. The water from the faucet flows through the main water supply passage 84 and is discharged into the washing and dewatering tub 22 from the water injection port 84a. Meanwhile, as indicated by the solid arrows in FIG. 2 , water from the faucet flows to the detergent supply passage 96 through the auxiliary water supply passage 94 , the first three-way valve 93 and the supply pump 95 to flush away the liquid detergent. The liquid detergent washed away by the water is injected into the washing and dewatering tub 22 from the supply port 96a of the detergent supply passage 96 together with the water as indicated by the dashed-dotted arrow in FIG. 2 . When the water level in the washing and dewatering tub 22 reaches a predetermined washing water level, the main valve 82 and the sub-valve 83 are closed, and the water supply ends.
而且，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。在对衬衫等被清洗物进行洗涤时，当该被清洗物局部含有顽固的污垢时，用户在洗涤前先使用超声波清洗装置50来进行被清洗物的局部清洗。Then, in the fully automatic washing machine 1, the cleaning operation by the ultrasonic cleaning device 50 is performed. When washing an object to be cleaned such as a shirt, if the object to be cleaned partially contains stubborn dirt, the user uses the ultrasonic cleaning device 50 to locally clean the object to be cleaned before washing.
用户在进行清洗运转的情况下如图3的(a)所示将超声波清洗装置50从容纳部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8所示，阀切换机构230通过弹簧233的施加力而经由阀可动构件231向后方、即闭塞方向对阀体220施力。由此，阀体220将排水口211闭塞，排水口211成为封闭的状态。When performing the cleaning operation, the user pulls out the ultrasonic cleaning device 50 from the accommodating portion 17 as shown in FIG. 3( a ), and moves the ultrasonic cleaning portion 100 and the water storage portion 200 to the operating position. As shown in FIG. 8 , the valve switching mechanism 230 urges the valve body 220 backward, that is, in the closing direction, through the valve movable member 231 by the urging force of the spring 233 . Thereby, the valve body 220 closes the drain port 211, and the drain port 211 is in a closed state.
用户进行规定的开始操作以开始清洗运转。The user performs a predetermined start operation to start the cleaning operation.
当清洗运转开始时，最初由自动投放机构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被切换至使供给管92与供给泵95连通的状态。此外，第二三通阀97被切换至使上游侧供给路96b与清洗水供给路98连通的状态。而且，供给阀400关闭。当供给泵95工作时，洗涤剂盒91内的液体洗涤剂通过抽吸作用被排出。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按工作预定时间，由此，预定量的液体洗涤剂蓄于上游侧供给路96b。When the cleaning operation is started, the supply of the cleaning water into the storage tank 60 is first performed by the automatic feeding mechanism 90 . 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 with each other. In addition, the second three-way valve 97 is switched to a state in which the upstream supply passage 96b and the washing water supply passage 98 communicate with each other. Also, the supply valve 400 is closed. When the supply pump 95 operates, the liquid detergent in the detergent box 91 is discharged by suction. 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 operates for a predetermined time, whereby a predetermined amount of the liquid detergent is stored in the upstream supply passage 96b.
接着，第一三通阀93被切换至使副供水路94与供给泵95连通的状态，副阀83打开。如图2的实线箭头所示，来自水龙头的水经过副供水路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。水和液体洗涤剂被混合成清洗水。如图2的粗线箭头所示，清洗水经过清洗水供给路98流入贮留箱60内。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 communicate with each other, and the auxiliary valve 83 is opened. As indicated by the solid arrows in FIG. 2 , the water from the faucet flows to the detergent supply passage 96 through the auxiliary water supply passage 94 , the first three-way valve 93 , and the supply pump 95 , and washes away the liquid detergent. Water and liquid detergent are mixed into wash water. As indicated by the thick-line arrows in FIG. 2 , the washing water flows into the storage tank 60 through the washing water supply path 98 .
如图9的(b)所示，在贮留箱60中，从流入口66流入贮留箱60的第一 箱61内的清洗水如实线箭头所示经过流出口64、阀壳410以及流出口65流入第二箱62内。由此，清洗水蓄于第一箱61和第二箱62，使这些箱内的水位上升。当第二箱62内开始蓄留清洗水时，第一电极端子710立即与清洗水接触。As shown in FIG. 9( b ), in the storage tank 60 , the washing water flowing into the first tank 61 of the storage tank 60 from the inflow port 66 passes through the outflow port 64 , the valve case 410 , and the flow as indicated by the solid arrow. The outlet 65 flows into the second tank 62 . Thereby, the washing water is stored in the first tank 61 and the second tank 62, and the water level in these tanks is raised. When the washing water starts to be stored in the second tank 62, the first electrode terminal 710 is immediately brought into contact with the washing water.
在本实施方式中，通常，从自动投放机构90向第一箱61的流量比从第一箱61向第二箱62的流量多。因此，第一箱61的水位比第二箱62的水位先上升，第二箱62内的水位在到达清洗水与第二电极端子720接触的供水停止水位L1之前到达连通部63的位置。在这样的情况下，如图9的(b)的虚线箭头所示，清洗水从连通部63的喷嘴部63a被放出至第二箱62内。In the present embodiment, normally, the flow rate from the automatic injection mechanism 90 to the first tank 61 is larger than the flow rate from the first tank 61 to the second tank 62 . Therefore, the water level in the first tank 61 rises before the water level in the second tank 62 , and the water level in the second tank 62 reaches the position of the communication portion 63 before reaching the water supply stop level L1 at which the washing water contacts the second electrode terminal 720 . In such a case, the washing water is discharged into the second tank 62 from the nozzle portion 63a of the communication portion 63 as indicated by the broken line arrow in FIG.
当第二箱62内的水位上升并到达供水停止水位L1时，第二电极端子720与清洗水接触，一对电极端子710、720变为导通状态。由此，从检测电路800向控制部16输出检测信号。由控制部16关闭副阀83，来自自动投放机构90的清洗水的供给停止。其后，直至第一箱61内的水位与第二箱62内的水位相同，清洗水从第一箱61流向第二箱62，最终贮留箱60内的水位变为比供水停止水位L1稍高的规定水位L2。When the water level in the second tank 62 rises and reaches the water supply stop water level L1, the second electrode terminal 720 comes into contact with the washing water, and the pair of electrode terminals 710 and 720 are brought into a conductive state. Thereby, the detection signal is output from the detection circuit 800 to the control unit 16 . The sub-valve 83 is closed by the control unit 16, and the supply of the washing water from the automatic injection mechanism 90 is stopped. After that, until the water level in the first tank 61 is the same as the water level in the second tank 62, the washing water flows from the first tank 61 to the second tank 62, and finally the water level in the storage tank 60 becomes slightly higher than the water supply stop water level L1. High specified water level L2.
在此，在供给清洗水时，贮留箱60内的水面容易因水的流入压力等而发生起伏。因此，在使第一电极端子710的长度与第二电极端子720的长度相同并使第一电极端子710的前端的位置和与供水停止水位L1一致的第二电极端子720的前端的位置相同的情况下，在发生起伏时，清洗水与双方的电极端子710、720的接触会变得不稳定，因此水位的检测时刻容易发生波动。Here, when the washing water is supplied, the water surface in the storage tank 60 is likely to fluctuate due to the inflow pressure of the water and the like. Therefore, when the length of the first electrode terminal 710 is the same as the length of the second electrode terminal 720 and the position of the tip of the first electrode terminal 710 is the same as the position of the tip of the second electrode terminal 720 that matches the water supply stop water level L1 In this case, when fluctuation occurs, the contact between the washing water and both electrode terminals 710 and 720 becomes unstable, so that the detection timing of the water level tends to fluctuate.
对此，在本实施方式中，水位检测部700采用了通过使第一电极端子710比第二电极端子720长而使第一电极端子710的前端的位置低于第二电极端子720的前端的位置的结构。由此，能使第一电极端子710从第二箱62内的水位远低于供水停止水位L1的状态开始就接触清洗水。由此，由于清洗水与第一电极端子710的接触稳定，因此即使水面发生了起伏，水位的检测时刻也不易发生波动。In contrast, in the present embodiment, the water level detection unit 700 employs a method in which the position of the tip of the first electrode terminal 710 is lower than the tip of the second electrode terminal 720 by making the first electrode terminal 710 longer than the second electrode terminal 720 . the structure of the location. Thereby, the first electrode terminal 710 can be brought into contact with the washing water from the state where the water level in the second tank 62 is much lower than the water supply stop water level L1. Accordingly, since the contact between the washing water and the first electrode terminal 710 is stable, even if the water surface fluctuates, the detection timing of the water level is less likely to fluctuate.
需要说明的是，流过第一电极端子710与第二电极端子720之间电流会因清洗水的洗涤剂浓度而发生变化，来自检测电路800的检测信号的脉冲宽度会发生变化。控制部16在基于检测信号的脉冲宽度判断为洗涤剂不足或未含洗涤剂的情况下，通过未图示的通知部进行通知。It should be noted that the current flowing between the first electrode terminal 710 and the second electrode terminal 720 changes due to the detergent concentration of the washing water, and the pulse width of the detection signal from the detection circuit 800 changes. When it is determined that the detergent is insufficient or the detergent is not contained based on the pulse width of the detection signal, the control unit 16 notifies the notification unit, not shown, of the detergent.
这样，通过从自动投放机构90供给清洗水，规定的水量及规定的洗涤剂浓度的清洗水蓄于贮留箱60内。在本实施方式中，蓄于贮留箱60的清洗水的量设为能更换贮水桶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设为进行三次以上清洗运转的量。In this way, by supplying the washing water from the automatic feeding mechanism 90 , the washing water of a predetermined amount of water and a predetermined detergent concentration is stored in the storage tank 60 . In the present embodiment, the amount of the washing water stored in the storage tank 60 is set to an amount that can replace the washing water in the water storage tub 210 and perform two washing operations. In addition, the quantity of the washing|cleaning water stored in the storage tank 60 may be set as the quantity which performs a washing|cleaning operation three times or more.
接着，供给阀400打开。贮留箱60内的清洗水经过供给喷嘴500从放出口501被放出至贮水桶210内。清洗水蓄于贮水桶210内，贮水桶210内的水位上升。当如图8的点划线所示贮水桶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内的气压与外部的气压相平衡。由此，在保持供给阀400打开的状态不变的情况下来自贮留箱60的供水停止。Next, the supply valve 400 is opened. The washing water in the storage tank 60 is discharged into the water storage tub 210 from the discharge port 501 through the supply nozzle 500 . The cleaning water is stored in the water storage tub 210, and the water level in the water storage tub 210 rises. When the water level in the water tank 210 rises to the height of the discharge port 501 and the discharge port 501 is blocked by the washing water as indicated by the dashed line in FIG. As a result, the water supply from the storage tank 60 is stopped while the open state of the supply valve 400 is maintained.
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 the water storage bucket 210 is filled with cleaning water, the user places the dirt adhering part of the object to be cleaned, such as the collar of a shirt, on the water storage bucket 210 from the front of the ultrasonic cleaning part 100 , that is, the connection between the water storage bucket 210 and the ultrasonic generator 110 between the vibration horns 112 .
被清洗物的污垢附着部分被蓄于贮水桶210内的清洗水浸没，浸透至被清洗物的内部的清洗水渗出表面。呈现出在被清洗物的表面形成有薄的水层而振动变幅杆112与该水层接触的状态。需要说明的是，当被清洗物吸水从而贮水桶210内的水位下降，供给喷嘴500的放出口501不被清洗水堵住时，从贮留箱60向贮水桶210内补给清洗水直至放出口501再次被清洗水堵住为止。由此，贮水桶210内的水位即水量被维持在适当的状态。The dirt adhering portion of the object to be cleaned is submerged by the washing water stored in the water storage tub 210 , and the washing water that has penetrated into the inside of the object to be cleaned seeps out to the surface. A thin water layer is formed on the surface of the object to be cleaned, and the vibration 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 tank 210 drops, and the discharge port 501 of the supply nozzle 500 is not blocked by the cleaning water, the cleaning water is supplied from the storage tank 60 to the water storage tank 210 until the discharge port 501 is blocked by the cleaning water again. Thereby, the water level in the water storage tank 210, that is, the amount of water is maintained in an appropriate state.
在供给阀400打开后直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处于待机状态。在此期间，向贮水桶210蓄留清洗水，向蓄有清洗水的贮水桶210中放置被清洗物。当经过了待机时间时，对超声波振子111进行通电来使超声波发生体110工作。After the supply valve 400 is opened, the ultrasonic transducer 111 is not energized until a predetermined standby time elapses, and the ultrasonic generator 110 is in a standby state. During this period, the washing water is stored in the water storage tub 210, and the object to be washed is placed in the water storage tub 210 in which the washing water is stored. When the standby time has elapsed, the ultrasonic transducer 111 is energized to operate the ultrasonic generator 110 .
图10的(a)至(c)是用于对由超声波清洗装置50实现的被清洗物的去污进行说明的图。(a)-(c) of FIG. 10 is a figure for demonstrating the decontamination of the to-be-cleaned object by the ultrasonic cleaning apparatus 50. FIG.
当超声波发生体110工作时，从振动变幅杆112的前端产生超声波，超声波振动经由振动变幅杆112周围的清洗水被传递给被清洗物内部的清洗水。如图10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发生减压和加压，在压力变低的部分产生真空的空腔。即，呈现出在被清洗物的受污 部分存在许多空腔的状态。接着，如图10的(b)所示，当空腔部分的压力升高，空腔被该压力压破而被破坏时，会对被清洗物的受污部分产生冲击波。通过该冲击波，污垢从被清洗物中分离。如图10的(c)所示，来自振动变幅杆112的超声波振动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，从被清洗物中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，因此变得容易从被清洗物中剥离污垢。而且，通过清洗水中所含的洗涤剂的作用，也容易从被清洗物中剥离污垢，此外，污垢变得不易再次附着于被清洗物。像这样，从被清洗物中去除污垢。When the ultrasonic generator 110 operates, ultrasonic waves are generated from the front end of the vibration horn 112 , and the ultrasonic vibration is transmitted to the cleaning water inside the object to be cleaned through the cleaning water around the vibration horn 112 . As shown in FIG. 10( a ), inside the object to be cleaned, decompression and pressurization are alternately generated by the action of ultrasonic vibration, and a vacuum cavity is generated in the part where the pressure becomes low. That is, there is a state in which many cavities exist in the contaminated portion of the object to be cleaned. Next, as shown in FIG. 10( b ), when the pressure of the cavity portion rises and the cavity is crushed and destroyed by the pressure, a shock wave is generated on the contaminated portion of the object to be cleaned. By this shock wave, the dirt is separated from the object to be cleaned. As shown in FIG. 10( c ), the ultrasonic vibration from the vibration horn 112 generates a water flow from the inside of the object to be cleaned to the water storage tub 210 , and the dirt separated from the object to be cleaned is discharged to the in the water storage bucket 210. In the water storage tub 210, since convection is generated by the above-mentioned water flow, it becomes easy to peel off the dirt from the object to be washed. Furthermore, the action of the detergent contained in the washing water also makes it easy to peel off the dirt from the object to be cleaned, and furthermore, it becomes difficult for the dirt to adhere to the object to be cleaned again. In this way, dirt is removed from the wash.
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的动作停止，清洗运转结束。When the cleaning of the object to be cleaned is completed, the user performs a predetermined end operation to end the cleaning operation. The operation of the ultrasonic generator 110 is stopped, and the cleaning operation ends.
在不接着进行新的清洗运转的情况下，如图3的(b)和(c)所示，用户将超声波清洗装置50容纳于容纳部17，使超声波清洗部100和贮水部200向待机位置移动。当如图7所示贮水部200移动至待机位置时，在阀切换机构230中，阀可动构件231的后端部231a与排水承接部70的后表面抵接，被这些肋74按压，抵抗弹簧233的施加力而相对于贮水部200向前方向移动。连接于阀可动构件231的阀体220相对于贮水桶210的排水口211向前方即打开方向移动，排水口211打开。由此，蓄于贮水桶210的清洗水和残留于贮留箱60内的清洗水经过排水口211被排出。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被排出。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被排出机外。When a new cleaning operation is not performed next, as shown in FIGS. 3( b ) and ( c ), the user accommodates the ultrasonic cleaning device 50 in the accommodating portion 17 , and causes the ultrasonic cleaning portion 100 and the water storage portion 200 to stand by. position moves. When the water storage portion 200 is moved to the standby position as shown in FIG. 7, in the valve switching mechanism 230, the rear end portion 231a of the valve movable member 231 abuts on the rear surface of the drain receiving portion 70, and is pressed by these ribs 74, It moves in the forward direction with respect to the water storage portion 200 against the urging force of the spring 233 . The valve body 220 connected to the valve movable member 231 moves forward with respect to the drain port 211 of the water storage tub 210, that is, in the opening direction, and the drain port 211 is opened. Thereby, the washing water stored in the water storage tank 210 and the washing water remaining in the storage tank 60 are discharged through the drain port 211 . The washing water discharged from the water discharge port 211 is received by the water discharge receiving portion 70 and discharged from the discharge 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 and is discharged out of the machine.
用户有时会想要更换贮水桶210的清洗水来继续清洗运转。在该情况下，用户进行使操作部232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移动至待机位置时同样地，阀可动构件231相对于贮水部200向前方向移动，阀体220向打开方向移动而排水口211打开。蓄于贮水桶210的清洗水经过排水口211被排水，经由排水承接部70、溢水管26以及排水软管41被排出机外。同时，新的清洗水从贮留箱60被供给至贮水桶210。The user sometimes wants to replace the washing water of the water storage tub 210 to continue the washing operation. In this case, the user performs a movement operation to move the operation unit 232 forward. As a result, in the valve switching mechanism 230, the valve movable member 231 moves in the forward direction relative to the water storage portion 200, the valve body 220 moves in the opening direction, and the drain port 211 is moved in the same manner as when the water storage portion 200 is moved to the standby position. Open. The washing water stored in the water tank 210 is drained through the drain port 211 , and is drained out of the machine via the drain receiving portion 70 , the overflow pipe 26 , and the drain hose 41 . At the same time, new washing water is supplied from the storage tank 60 to the water storage tub 210 .
如此，用户无需移动超声波清洗装置50就能在贮水部200维持于运转位置不变的情况下从贮水桶210排出清洗水，能将新的清洗水供给至贮水桶210内。其后，继续清洗运转。In this way, the user can discharge the cleaning water from the water storage tub 210 without moving the ultrasonic cleaning device 50 while the water storage unit 200 is maintained at the operating position, and can supply new cleaning water into the water storage tub 210 . Thereafter, the cleaning operation is continued.
在超声波清洗部100中，在重复清洗运转的期间，贮水桶210会变脏。在本实施方式中，贮水部200相对于主体部300可拆装，因此用户能从主体部300卸下贮水部200来进行贮水桶210的清洗。In the ultrasonic cleaning unit 100, while the cleaning operation is repeated, the water tank 210 becomes dirty. In this embodiment, since the water storage part 200 is detachable from the main body part 300 , the user can remove the water storage part 200 from the main body part 300 to clean the water storage tub 210 .
＜实施方式的效果＞<Effect of the embodiment>
以上，根据本实施方式，水位检测部700配置为包括从贮留箱60的顶面部向下方延伸的第一电极端子710和第二电极端子720且第一电极端子710比第二电极端子720长。根据该结构，能使第一电极端子710的前端的位置比第二电极端子720的前端的位置低，因此能使第一电极端子710从第二箱62内的水位低于供水停止水位L1的状态就开始接触清洗水。由此，即使水面发生了起伏，第一电极端子710与清洗水的接触也稳定。因此，水位的检测时刻不易发生波动，能高精度地检测贮留箱60内的水位。As described above, according to the present embodiment, the water level detection unit 700 is configured to include the first electrode terminal 710 and the second electrode terminal 720 extending downward from the top surface of the storage tank 60 and the first electrode terminal 710 is longer than the second electrode terminal 720 . According to this configuration, the position of the front end of the first electrode terminal 710 can be made lower than the position of the front end of the second electrode terminal 720, so that the water level of the first electrode terminal 710 in the second tank 62 can be made lower than the water supply stop water level L1. The state begins to contact the cleaning water. Accordingly, even if the water surface fluctuates, the contact between the first electrode terminal 710 and the washing water is stabilized. Therefore, the detection timing of the water level is less likely to fluctuate, and the water level in the storage tank 60 can be detected with high accuracy.
此外，根据本实施方式，贮留箱60在左右方向上的尺寸比前后方向上的尺寸大，一对电极端子710、720在左右方向上排列。根据该结构，能增大一对电极端子710、720的间隔，因此在向贮留箱60供给清洗水时，即使水面的一部分发生了由洗涤剂引起的起泡，双方的电极端子710、720也不易与该泡接触。由此，不易发生因与泡的接触而导致一对电极端子710、720变为导通状态从而对水位作出误检测这样的情况，能提高水位的检测精度。Further, according to the present embodiment, the size of the storage tank 60 in the left-right direction is larger than the size in the front-rear direction, and the pair of electrode terminals 710 and 720 are arranged in the left-right direction. According to this configuration, since the distance between the pair of electrode terminals 710 and 720 can be increased, when the cleaning water is supplied to the storage tank 60, even if a part of the water surface is foamed by the detergent, the electrode terminals 710 and 720 on both sides of the electrode It is also not easy to come into contact with the bubble. Thereby, the pair of electrode terminals 710 and 720 are less likely to be in the conductive state due to the contact with the bubble, thereby erroneously detecting the water level, and the detection accuracy of the water level can be improved.
而且，根据本实施方式，在贮留箱60中，第一箱61的流入口66在第一电极端子710和第二电极端子720所排列的左右方向上相对于第一电极端子710位于与第二电极端子720相反的一侧。根据上述的结构，在清洗水从流入口66流入贮留箱60时，第一电极端子710成为水流的上游侧，第二电极端子720成为水流的下游侧。下游侧比上游侧容易平息起伏，因此第二电极端子720与水的接触变得稳定。因此，水位的检测时刻更不易发生波动，能更高精度地检测贮留箱60内的水位。Furthermore, according to the present embodiment, in the storage tank 60 , the inflow port 66 of the first tank 61 is located on the left and right sides with respect to the first electrode terminal 710 relative to the first electrode terminal 710 in the left-right direction in which the first electrode terminal 710 and the second electrode terminal 720 are arranged. The opposite side of the two electrode terminals 720 . According to the above configuration, when the washing water flows into the storage tank 60 from the inflow port 66, the first electrode terminal 710 becomes the upstream side of the water flow, and the second electrode terminal 720 becomes the downstream side of the water flow. The downstream side is easier to calm down than the upstream side, so the contact between the second electrode terminal 720 and the water becomes stable. Therefore, the detection timing of the water level is less likely to fluctuate, and the water level in the storage tank 60 can be detected with higher accuracy.
而且，根据上述实施方式，贮留箱60包括来自自动投放机构90的水所流入的第一箱61和与该第一箱61在彼此的下部连接的第二箱62，一对电极端子710、720配置于第二箱62。第二箱62与来自自动投放机构90的水所直接流入第一箱61相比水面的起伏变少。根据上述的结构，一对电极端子710、720配置于第二箱62，因此水位的检测时刻更不易发生波动，能更高精度地检测贮留 箱60内的水位。Furthermore, according to the above-described embodiment, the storage tank 60 includes the first tank 61 into which the water from the automatic injection mechanism 90 flows, the second tank 62 connected to the first tank 61 at the lower part of each other, the pair of electrode terminals 710, 720 is arranged in the second box 62 . The second tank 62 has less undulations in the water surface than when the water from the automatic injection mechanism 90 flows directly into the first tank 61 . According to the above configuration, since the pair of electrode terminals 710 and 720 are arranged in the second tank 62, the detection timing of the water level is less likely to fluctuate, and the water level in the storage tank 60 can be detected with higher accuracy.
而且，根据上述实施方式，贮留箱60隔着供给阀400被分为第一箱61和第二箱62，第一箱61的流出口64和第二箱62的流出口65与供给阀400的左右的入口411、412连接。根据该结构，能使分别来自第一箱61和第二箱62的清洗水经过供给阀400流出，因此能从贮留箱60将清洗水顺畅地供给至贮水桶210。此外，能使从流入口66流入第一箱61内的水经过供给阀400流入第二箱62而蓄于第二箱62内。Furthermore, according to the above-described embodiment, the storage tank 60 is divided into the first tank 61 and the second tank 62 via the supply valve 400 , the outflow port 64 of the first tank 61 and the outflow port 65 of the second tank 62 , and the supply valve 400 The left and right inlets 411 and 412 are connected. According to this configuration, since the washing water from the first tank 61 and the second tank 62 can flow out through the supply valve 400 , the washing water can be smoothly supplied from the storage tank 60 to the water storage tub 210 . In addition, the water flowing into the first tank 61 from the inflow port 66 can flow into the second tank 62 through the supply valve 400 and be stored in the second tank 62 .
以上，对本发明的实施方式进行了说明，但本发明不由上述实施方式进行任何限制，此外，本发明的实施方式也可以在上述以外进行各种变更。The embodiments of the present invention have been described above, but the present invention is not limited by the above-described embodiments, and the embodiments of the present invention may be modified in various ways other than those described above.
例如，在上述实施方式中，贮留箱60配置为为由第一箱61和第二箱62这两个箱构成。然而，贮留箱60也可以配置为由一个箱构成。For example, in the said embodiment, the storage tank 60 is arrange|positioned so that it may consist of two tanks of the 1st tank 61 and the 2nd tank 62. However, the storage tank 60 may be configured to consist of one tank.
此外，贮留箱60的形状不限于上述实施方式所示的形状，可以是任何形状。同样地，供给阀400相对于贮留箱60的位置也不限于上述实施方式所示的位置，可以是任何位置。同样地，第一电极端子710和第二电极端子720的形状也不限于上述实施方式所示的形状，只要是长条形状，可以是任何形状。In addition, the shape of the storage tank 60 is not limited to the shape shown in the said embodiment, Any shape may be sufficient.

However, the front end of the first electrode terminal 710 only needs to be positioned lower than the front end of the second electrode terminal 720 , and does not need to approach or contact the bottom surface of the second case 62 .
而且，在上述实施方式中，在第二箱62中，第一电极端子710配置于左侧即靠近第一箱61那一侧，第二电极端子720配置于右侧即远离第一箱61那一侧。然而，在第二箱62中，也可以将第二电极端子720配置于左侧并将第一电极端子710配置于右侧。Furthermore, in the above-described embodiment, in the second box 62 , the first electrode terminal 710 is arranged on the left side, that is, the side close to the first box 61 , and the second electrode terminal 720 is arranged on the right side, that is, the side away from the first box 61 . side. However, in the second box 62, the second electrode terminal 720 may be arranged on the left side and the first electrode terminal 710 may be arranged on the right side.
而且，在上述实施方式中，将混合了洗涤剂的水即清洗水从自动投放机构90供给至贮留箱60。然而，只要最终在贮留箱60蓄有清洗水即可，因此向贮留箱60至少供给水即可。例如也可以设为：从不包括自动投放机构90的供水单元80向贮留箱60供水，水与被另外投放至贮留箱60内的洗涤剂混合。在该情况下，理想的是将洗涤剂自动投放至贮留箱60，但也可以由人手投放。Moreover, in the said embodiment, the washing water which is the water mixed with detergent is supplied to the storage tank 60 from the automatic injection|throwing-in mechanism 90. However, as long as the cleaning water is finally stored in the storage tank 60 , at least water may be supplied to the storage tank 60 . For example, water may be supplied to the storage tank 60 from the water supply unit 80 that does not include the automatic injection mechanism 90 , and the water may be mixed with the detergent separately injected into the storage tank 60 . In this case, it is desirable to put the detergent into the storage tank 60 automatically, but it may be put in manually.
而且，在上述实施方式中，自动投放机构90可以设为能自动投放洗涤剂和 柔顺剂的结构。在该情况下，设有容纳液体柔顺剂的柔顺剂盒。柔顺剂盒经由供给管和三通阀与副供水路94相连。在漂洗过程时，通过与来自洗涤剂盒91的洗涤剂的供给相同的动作，将柔顺剂箱内的柔顺剂供给至洗涤脱水桶22内。Furthermore, in the above-described embodiment, the automatic dispensing mechanism 90 may be configured to automatically dispense detergent and softener. In this case, there is a softener cartridge containing the liquid softener. The softener cartridge is connected to the auxiliary water supply line 94 via a supply pipe and a three-way valve. During the rinsing process, the softener in the softener tank is supplied into the washing and dewatering tub 22 by the same operation as the supply of the detergent from the detergent box 91 .
而且，在上述实施方式中，示出了具备超声波清洗装置50的全自动洗衣机1。然而，本发明也能应用于全自动洗衣机1以外的洗衣机，例如滚筒洗衣机。而且，本发明也能应用于具有烘干功能的全自动洗干一体机、滚筒洗干一体机。Moreover, in the said embodiment, the fully automatic washing machine 1 provided with the ultrasonic cleaning apparatus 50 was shown.
