Description

洗衣机washing machine 技术领域Technical field
本发明涉及一种洗衣机。The present invention relates to a washing machine.
背景技术Background technique
以往,已知一种洗衣机,其用循环泵汲取蓄于外桶的底部的水,并将汲取的水从洗涤脱水桶的上方朝向洗涤脱水桶内喷洒。例如,专利文献1中记载了一种洗衣机,其具备具有宽度大的返回口的水路部,将用循环泵汲取的洗涤水从返回口向内桶即洗涤脱水桶内大面积喷洒。Conventionally, there has been known a washing machine which draws water stored in the bottom of the outer tub with a circulation pump and sprays the extracted water from above the washing and dewatering tub toward the washing and dewatering tub. For example, Patent Document 1 describes a washing machine including a water passage portion having a large return port, and sprays the washing water drawn by the circulation pump from the return port to the inner tub, that is, the washing and dewatering tub.
专利文献1的洗衣机的目的在于将洗涤水大面积喷洒而使其良好地浸透洗涤物,因此没有考虑喷洒的洗涤水的强度,洗涤水以近乎自由落下的状态从返回口排出而与洗涤物接触。因此,几乎不能期待通过洗涤水与洗涤物接触时施加的力来洗净洗涤物。因此,在向洗涤脱水桶内投入了大量的洗涤物的情况下,难以通过喷洒的洗涤水良好地洗净上侧的洗涤物。The purpose of the washing machine of Patent Document 1 is to spray the washing water over a large area so as to saturate the laundry well, so that the strength of the sprayed washing water is not taken into consideration, and the washing water is discharged from the return port in a state of almost free fall to contact with the laundry. . Therefore, it is almost impossible to expect to wash the laundry by the force applied when the washing water comes into contact with the laundry. Therefore, in the case where a large amount of laundry is put into the washing and dewatering tub, it is difficult to wash the upper laundry well by the sprayed washing water.

发明内容Summary of the invention
发明所要解决的问题Problems to be solved by the invention
本发明是解决这样的问题的发明,其目的在于提供一种洗衣机,其能良好地洗净大量的洗涤物。The present invention is an invention for solving such a problem, and an object thereof is to provide a washing machine capable of washing a large amount of laundry well.
用于解决问题的方案Solution to solve the problem
本发明的主要方案的洗衣机具备:外桶,弹性地支承于箱体内;洗涤脱水桶,配置于所述外桶内;泵,配置于所述箱体内,汲取蓄于所述外桶内的水;以及喷头,具有面向所述洗涤脱水桶内的喷嘴,将由所述泵汲取的水从所述喷嘴朝向下方的所述洗涤脱水桶内喷射。A washing machine according to a main aspect of the present invention includes: an outer tub elastically supported in the casing; a washing dewatering bucket disposed in the outer tub; and a pump disposed in the casing to extract water stored in the outer tub And a spray head having a nozzle facing the washing and dewatering tank, and spraying water drawn by the pump from the nozzle toward the lower washing dewatering tank.
根据上述结构,从喷头的喷嘴喷射的水与洗涤脱水桶内的上侧的洗涤物接 触,因此能通过接触的水的冲击来洗净上侧的洗涤物。由此,即使是在大量的洗涤物被投入洗涤脱水桶内的情况下,也能降低在洗涤脱水桶内的上侧的洗涤物与下侧的洗涤物之间产生的清洗不均匀,能良好地洗净洗涤物。According to the above configuration, the water ejected from the nozzle of the head is in contact with the laundry on the upper side in the washing and dewatering tub, so that the washing on the upper side can be washed by the impact of the contacted water. Thereby, even when a large amount of laundry is put into the washing and dewatering tub, the cleaning unevenness between the laundry on the upper side and the laundry in the lower side in the washing and dewatering tub can be reduced, and the washing can be improved. Wash the laundry.
在本方案的洗衣机中,可以采用如下结构,即,还具备:波轮,配置于所述洗涤脱水桶内的底部;驱动部,用于驱动所述波轮;以及控制部,所述喷头以从所述喷嘴向所述洗涤脱水桶的与中心轴偏离的局部区域喷水的方式配置。这种情况下,在清洗过程中向所述外桶内供水时,所述控制部使所述泵工作的同时通过所述驱动部使所述波轮旋转。In the washing machine of the present aspect, a structure may be adopted, that is, a pulsator disposed at a bottom portion of the washing and dewatering tub, a driving portion for driving the pulsator, and a control portion, the shower head The water is sprayed from the nozzle to a partial area of the washing and dewatering tub that is offset from the central axis. In this case, when the water is supplied into the outer tub during the washing process, the control unit rotates the pulsator by the driving unit while the pump is operating.
根据上述结构,在大量的洗涤物被投入到洗涤脱水桶内的情况下,局部区域的洗涤物因为从喷嘴喷射的水的压力等而大幅度下沉,与其他区域的洗涤物之间容易产生高度的不平衡。而且,当波轮在这种状态下旋转时,其他区域的洗涤物容易向变低的局部区域移动。由此,从向外桶内供水的时间点开始,洗涤物容易以上下互换的方式运动,容易对洗涤物产生洗涤物之间的摩擦等机械力。因此,能从向外桶内供水的时间点开始良好地洗净大量的洗涤物。According to the above configuration, in the case where a large amount of laundry is put into the washing and dewatering tub, the laundry in the partial area is largely sunk due to the pressure of the water sprayed from the nozzle, etc., and is easily generated between the laundry in other areas. High imbalance. Moreover, when the pulsator is rotated in this state, the laundry in other areas is liable to move to a lower local area. Thereby, from the time point of water supply to the outer tub, the laundry is easily moved in the above-described manner, and it is easy to generate mechanical force such as friction between the laundry. Therefore, it is possible to wash a large amount of laundry well from the time point of supplying water into the outer tub.
在本方案的洗衣机中,在所述喷头,在面向所述洗涤脱水桶内的面,以按规定的间隔排列的方式设置有多个所述喷嘴。In the washing machine of the present aspect, a plurality of the nozzles are disposed on the surface facing the washing and dewatering tub at a predetermined interval.
根据上述结构,即使洗涤物与部分喷嘴接触而堵住其喷射口,与此相应地提高了压力而增强了水势的水也会从其他喷嘴被喷射。因此,由于喷水的喷嘴的个数减少会通过水势的增加而得到补偿,因此洗净上侧的洗涤物的效果不容易降低。According to the above configuration, even if the laundry comes into contact with a part of the nozzle to block the ejection opening thereof, the water which is increased in pressure and the water potential is enhanced is ejected from the other nozzles. Therefore, since the number of nozzles for water spray is reduced by the increase of the water potential, the effect of washing the upper laundry is not easily lowered.
在本方案的洗衣机中,能在所述喷头,在比所述喷嘴更靠近所述洗涤脱水桶的内周面侧,设置供来自所述泵的水导入的导入口。这种情况下,所述喷嘴中的水的喷射口朝向相对于所述喷头的正下方往所述内周面侧的相反侧倾斜的方向。In the washing machine of the present aspect, an inlet for introducing water from the pump can be provided on the inner peripheral surface side of the washing and dewatering tub than the nozzle. In this case, the injection port of the water in the nozzle faces a direction inclined to the opposite side of the inner peripheral surface side with respect to the immediately below the head.
当喷头采用在比喷嘴更靠近洗涤脱水桶的内周面侧设置有供来自泵的水导入的导入口的结构时,在喷头内,会产生来自导入口的水相对于喷嘴与导入口的相反侧的壁接触并折返而朝向喷射口这样的水流,从而从喷射口喷射的水容易朝向洗涤脱水桶的内周面侧。When the head is provided with a structure for introducing an inlet port for introducing water from the pump closer to the inner peripheral surface side of the washing and dewatering tub than the nozzle, water in the nozzle is opposite to the nozzle and the inlet in the nozzle. The side wall contacts and folds back toward the water flow of the injection port, so that the water sprayed from the injection port is easily directed toward the inner peripheral surface side of the washing and dewatering tub.
根据上述结构,喷射口朝向相对于所述喷头的正下方往所述内周面侧的相反侧倾斜的方向,因而能从喷射口向喷头的大致正下位置喷水。由此,能防止 以贴着洗涤脱水桶的内周面侧的方式从喷嘴喷水而导致喷射的水不容易与洗涤物接触的情况。According to the above configuration, the injection port is directed in a direction inclined to the opposite side of the inner peripheral surface side from the immediately below the head, so that water can be sprayed from the injection port to the substantially right lower position of the head. Thereby, it is possible to prevent water sprayed from being sprayed from the nozzle so as to be in contact with the laundry on the inner peripheral surface side of the washing and dewatering tub.
在本方案的洗衣机中,可以采用如下结构,即,还具备:过滤器壳体,供被所述泵吸入的水通过;以及过滤器,收容于所述过滤器壳体内。In the washing machine of the present aspect, a configuration may be adopted in which a filter case is provided through which water sucked by the pump passes, and a filter is housed in the filter case.
根据上述结构,出自洗涤物而混入水中的线屑、污垢等被过滤器捕集,因而能防止线屑等进入泵内或喷头内。According to the above configuration, the lint, dirt, and the like which are mixed in the water from the laundry are collected by the filter, so that it is possible to prevent the thread from entering the inside of the pump or the head.
在采用上述结构的情况下,可以采用如下结构,即,所述泵包括:泵壳体、配置于该泵壳体内的叶轮、以及用于使该叶轮旋转的马达。这种情况下,所述过滤器壳体中的水的流出口与所述泵壳体中的水的吸入口正对,在流出口与吸入口之间连接有连接管。In the case of employing the above configuration, a configuration may be employed in which the pump includes a pump casing, an impeller disposed in the pump casing, and a motor for rotating the impeller. In this case, the outflow port of the water in the filter case faces the suction port of the water in the pump casing, and a connection pipe is connected between the outflow port and the suction port.
采用这样的结构的话,由于能将连接管配置为直线状,因而能抑制连接管内的压力损失,能用泵良好地汲取外桶内的水。According to this configuration, since the connecting pipe can be arranged in a straight line, the pressure loss in the connecting pipe can be suppressed, and the water in the outer tub can be satisfactorily pumped by the pump.

Drive unit 77 and the like.
全自动洗衣机1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 a washing operation in various operation modes. In the washing operation, the washing process, the intermediate dehydration process, the rinsing process, and the final dehydration process are sequentially performed.
在清洗过程以及漂洗过程中,在洗涤脱水桶24内蓄有水的状态下,波轮26向右以及向左旋转。洗涤脱水桶24内的洗涤物通过因波轮26的旋转而产生的水流等的作用,被清洗或者漂洗。在清洗过程中,供给至洗涤脱水桶24内的水中混入有洗涤剂,因此也会发挥由该洗涤剂带来的洗净性能。In the washing process and the rinsing process, the pulsator 26 is rotated to the right and to the left in a state where water is stored in the washing and dewatering tub 24. The laundry in the washing and dewatering tub 24 is washed or rinsed by the action of a water flow or the like generated by the rotation of the pulsator 26. In the washing process, the detergent supplied to the water in the washing and dewatering tub 24 is mixed with the detergent, so that the washing performance by the detergent is also exerted.
在中间脱水过程以及最终脱水过程中,洗涤脱水桶24以及波轮26一体地高速旋转。洗涤物通过在洗涤脱水桶24产生的离心力的作用而被脱水。During the intermediate dewatering process and the final dewatering process, the washing and dewatering tub 24 and the pulsator 26 are integrally rotated at a high speed. The laundry is dehydrated by the action of centrifugal force generated in the washing dewatering bucket 24.
在本实施方式中,至少在清洗过程中,在外桶20内蓄有混入了洗涤剂的水的状态下,循环泵62工作。外桶20内的水被汲取并供给至喷头61。从喷头61的各个喷嘴105,如图2的单点划线所示,水朝向洗涤脱水桶24内的从中心轴C向后方偏离的局部区域喷射。喷射的水通过波轮26的旋转而被搅拌,与向洗涤脱水桶24内的后侧移动过来的上侧的洗涤物接触。洗涤物中不仅被水中所含 的洗涤剂浸透,还被赋予与高压的水接触时的冲击带来的机械力。由此,由波轮26产生的水流所不容易到达的上侧的洗涤物被洗净。In the present embodiment, the circulation pump 62 is operated in a state in which the water in which the detergent is mixed is stored in the outer tub 20 at least during the cleaning process. The water in the outer tub 20 is drawn and supplied to the head 61. From the respective nozzles 105 of the head 61, as indicated by the alternate long and short dash line in Fig. 2, water is ejected toward a partial region in the washing and dewatering tub 24 which is displaced rearward from the central axis C. The sprayed water is stirred by the rotation of the pulsator 26, and comes into contact with the upper laundry moving toward the rear side in the washing and dewatering tub 24. The laundry is not only impregnated with the detergent contained in the water but also imparted mechanical force by the impact when it comes into contact with high-pressure water. Thereby, the laundry on the upper side which is not easily reached by the water flow generated by the pulsator 26 is washed.
这样,靠近水面或者从水面露出的上侧的洗涤物能被良好地洗净,从而能投入大量洗涤物直至达到洗涤脱水桶24内的上方,能不改变洗涤脱水桶24的大小就增加洗涤容量。Thus, the laundry on the upper side close to the water surface or exposed from the water surface can be well washed, so that a large amount of laundry can be put in until reaching above the washing dewatering tub 24, and the washing capacity can be increased without changing the size of the washing and dewatering tub 24. .
此外,喷头61在其长尺寸方向上按规定的间隔设置有多个喷嘴105,因而即使洗涤物与部分喷嘴105接触而堵住喷射口106,与部分喷射口106被堵住相应地提高了压力而增强了水势的水也会从其他的喷嘴105的喷射口106被喷射。因此,喷水的喷嘴105的个数减少会通过水势的增加而得到补偿,洗净上侧的洗涤物的效果不容易降低。Further, the head 61 is provided with a plurality of nozzles 105 at a predetermined interval in the longitudinal direction thereof, so that even if the laundry contacts the partial nozzles 105 to block the ejection openings 106, the partial ejection openings 106 are blocked to increase the pressure accordingly. The water having enhanced water potential is also ejected from the ejection openings 106 of the other nozzles 105. Therefore, the number of nozzles 105 for water spray is reduced by the increase of the water potential, and the effect of washing the upper laundry is not easily lowered.
进而,由于各个喷嘴105的喷射口106具有在喷嘴105的排列方向上长的形状,因而喷射的水在排列方向上叠加而容易与洗涤物接触,水容易无遗漏地与洗涤物接触。Further, since the ejection openings 106 of the respective nozzles 105 have a shape elongated in the direction in which the nozzles 105 are arranged, the sprayed water is superimposed in the arrangement direction and is easily brought into contact with the laundry, and the water is easily brought into contact with the laundry without any omission.
进而,在喷头61中,导入口104位于各个喷嘴105的后方。因此,在喷头61内,如图3的(c)的实线箭头所示,除了来自导入口104的水直接朝向各个喷嘴105的喷射口106那样的水流之外,还会产生来自导入口104的水与前侧的壁碰撞并折返而朝向喷射口106那样的水流。因此,在各个喷嘴105的喷射口106朝向正下方的情况下,根据折返的水流的强度,从喷射口106喷射的水容易朝向正下方的稍后方。在本实施方式中,由于各个喷嘴105的喷射口106朝向斜前方,因而从喷射口106喷射的水会向喷嘴105的大致正下方位置喷射。Further, in the head 61, the introduction port 104 is located behind each nozzle 105. Therefore, in the head 61, as indicated by the solid arrows in FIG. 3(c), in addition to the water flow from the inlet 104 directly toward the injection port 106 of each nozzle 105, a flow from the inlet 104 is generated. The water collides with the front side wall and folds back toward the water flow like the injection port 106. Therefore, in the case where the injection port 106 of each nozzle 105 faces directly downward, the water ejected from the injection port 106 is likely to face the later side immediately below according to the intensity of the folded water flow. In the present embodiment, since the injection port 106 of each nozzle 105 faces obliquely forward, water ejected from the injection port 106 is ejected toward a substantially right position of the nozzle 105.
从外桶20排出并被吸入循环泵62的水从过滤器壳体320内流过。出自洗涤物并混入水中的线屑、污垢被过滤器310捕集。由此,能防止线屑缠在循环泵62的叶轮220上,或者线屑堵塞喷头61的各个喷嘴105的喷射口106。这里,在过滤器壳体320的流出口326与泵壳体210的吸入口211之间,以呈直线状的方式配置有第二连接管65。因此,能抑制第二连接管65内的压力损失。Water discharged from the outer tub 20 and sucked into the circulation pump 62 flows through the filter housing 320. The lint and dirt from the laundry and mixed into the water are trapped by the filter 310. Thereby, it is possible to prevent the swarf from being caught on the impeller 220 of the circulation pump 62, or the swarf clogging the injection port 106 of each nozzle 105 of the head 61. Here, the second connecting pipe 65 is disposed linearly between the outflow port 326 of the filter case 320 and the suction port 211 of the pump casing 210. Therefore, the pressure loss in the second connecting pipe 65 can be suppressed.
图6是表示本实施方式的清洗过程中的控制动作的流程图。Fig. 6 is a flowchart showing a control operation in the cleaning process of the embodiment.
当清洗过程开始时,控制部71打开供水阀51(S1)。由此,从供水单元50向外桶20内供水。外桶20内蓄有混入了洗涤剂的水。控制部71基于水位传感器90的水位检测结果,监控外桶20内的水位是否达到了泵启动水位(S2)。当外桶20内蓄水至泵启动水位时,能在启动循环泵62后将水汲取至喷头61。When the washing process is started, the control portion 71 opens the water supply valve 51 (S1). Thereby, water is supplied from the water supply unit 50 to the inside of the tub 20. Water in which the detergent is mixed is stored in the outer tub 20. The control unit 71 monitors whether or not the water level in the outer tub 20 has reached the pump start water level based on the water level detection result of the water level sensor 90 (S2). When the water in the outer tub 20 is stored to the pump start water level, the water can be taken to the spray head 61 after the circulation pump 62 is started.
当外桶20内的水位达到泵启动水位时(S2:是),控制部71使循环泵62工作(S3)。然后,当循环泵62的工作开始后经过了规定时间例如约30秒时(S4:是),控制部71使驱动马达31带有停顿地向右以及向左交替旋转,使波轮26带有停顿地向右以及向左交替旋转(S5)。例如,能将驱动马达31的向左以及向右的接通时间设为2秒左右,能将停止时间设为0.5秒左右的时间。向左的接通时间和向右的接通时间可以不设为相同时间而设为不同的时间。When the water level in the outer tub 20 reaches the pump start water level (S2: YES), the control unit 71 causes the circulation pump 62 to operate (S3). Then, when a predetermined time, for example, about 30 seconds has elapsed after the start of the operation of the circulation pump 62 (S4: YES), the control unit 71 alternately rotates the drive motor 31 to the right and left with a pause, so that the pulsator 26 is provided with Rotate alternately to the right and to the left (S5). For example, the ON time to the left and the right of the drive motor 31 can be set to about 2 seconds, and the stop time can be set to about 0.5 second. The turn-on time to the left and the turn-on time to the right may be set to different times without being set to the same time.
控制部71监控外桶20内的水位是否达到了根据洗涤物的负荷量而设定的洗涤水位(S6)。当外桶20内的水位达到了洗涤水位时(S6:是),控制部71关闭供水阀51(S7)。通过供水单元50进行的向外桶20内的供水停止。循环泵62以及波轮26继续工作。The control unit 71 monitors whether or not the water level in the outer tub 20 has reached the washing water level set according to the load amount of the laundry (S6). When the water level in the outer tub 20 reaches the washing water level (S6: YES), the control unit 71 closes the water supply valve 51 (S7). The water supply in the outer tub 20 by the water supply unit 50 is stopped. The circulation pump 62 and the pulsator 26 continue to operate.
控制部71监控外桶20内的水位达到洗涤水位后是否经过了规定的清洗时间(S8)。当经过了清洗时间时(S8:是),控制部71使循环泵62停止,并且使驱动马达31停止而使波轮26(S9)停止。之后,控制部71打开排水阀40(S10)。水从外桶20内被排出,清洗过程结束。The control unit 71 monitors whether or not a predetermined washing time has elapsed after the water level in the outer tub 20 reaches the washing water level (S8). When the cleaning time has elapsed (S8: YES), the control unit 71 stops the circulation pump 62, stops the drive motor 31, and stops the pulsator 26 (S9). Thereafter, the control unit 71 opens the drain valve 40 (S10). The water is discharged from the outer tub 20 and the washing process is completed.
图7的(a)至(e)是用于对本实施方式的大量的洗涤物被投入到洗涤脱水桶24内的情况下的供水时的洗涤物的运动进行说明的示意图。(a) to (e) of FIG. 7 are schematic views for explaining the movement of the laundry at the time of water supply in the case where a large amount of laundry of the present embodiment is put into the washing and dewatering tub 24.
在本实施方式的全自动洗衣机1中,如图7的(a)所示,将洗涤物投入至洗涤脱水桶24内比喷头61稍微偏下的位置。当开始从供水单元50供水时,混入有洗涤剂的水被蓄至外桶20内。In the fully automatic washing machine 1 of the present embodiment, as shown in FIG. 7(a), the laundry is put into a position in the washing and dewatering tub 24 that is slightly lower than the head 61. When the water supply from the water supply unit 50 is started, the water mixed with the detergent is stored in the outer tub 20.
如图7的(b)所示,当外桶20内蓄水至泵启动水位时,循环泵62工作,从喷头61的各个喷嘴105喷水,喷射的水与位于喷头61的下方的洗涤脱水桶24的后侧的洗涤物接触。在洗涤脱水桶24的后侧,洗涤物通过被水浸湿并且被水势推压而大幅度下沉,在洗涤脱水桶24的后侧与前侧之间产生洗涤物的显著的高度差。As shown in (b) of FIG. 7, when the outer tub 20 stores water to the pump start water level, the circulation pump 62 operates to spray water from the respective nozzles 105 of the head 61, and the sprayed water and the washing dehydration located below the head 61 The laundry on the back side of the tub 24 is in contact. On the rear side of the washing and dewatering tub 24, the laundry is largely sunk by being wetted by water and pushed by the water potential, and a significant height difference of the laundry is generated between the rear side and the front side of the washing and dewatering tub 24.
在这种状态下,如图7的(c)所示,当波轮26开始向左右方向旋转时,高度平衡不良,因此前侧的洗涤物向后侧的变低的部分移动。在洗涤脱水桶24的前侧,上侧的洗涤物不容易被波轮26搅拌,因此不容易大幅度运动。但是,由于这些洗涤物尚未被水浸湿而重量轻,因此如虚线箭头所示,在洗涤脱水桶24的下侧,当洗涤物被波轮26搅拌而从前侧向后侧移动时,容易被下侧的洗涤物顶起。In this state, as shown in FIG. 7(c), when the pulsator 26 starts to rotate in the left-right direction, the height balance is poor, and therefore the laundry on the front side moves to the lower portion of the rear side. On the front side of the washing and dewatering tub 24, the laundry on the upper side is not easily stirred by the pulsator 26, so that it is not easy to move at a large extent. However, since these laundry materials have not been wetted by water and are light in weight, as indicated by a broken line arrow, on the lower side of the washing and dewatering tub 24, when the laundry is stirred by the pulsator 26 and moved from the front side to the rear side, it is easy to be The laundry on the lower side is jacked up.
如图7的(d)所示,在洗涤脱水桶24的后侧,洗涤物因喷射的水而下沉,与在洗涤脱水桶24的前侧被顶起的上侧的洗涤物之间产生显著的高度差。由此,前侧的洗涤物向后侧的变低的部分移动。As shown in (d) of FIG. 7, on the rear side of the washing and dewatering tub 24, the laundry sinks due to the sprayed water, and is generated between the laundry on the upper side which is lifted on the front side of the washing and dewatering tub 24. Significant height difference. Thereby, the laundry on the front side moves to the lower portion of the rear side.
通过重复图7的(c)和(d)那样的动作,如图7的(e)所示,在向外桶20内进行供水期间,洗涤物容易以上下互换的方式运动。由此,容易对洗涤物产生洗涤物之间的摩擦等机械力。因此,能从向外桶20内供水的时间点开始良好地洗净大量的洗涤物。By repeating the operations of (c) and (d) of FIG. 7 , as shown in FIG. 7( e ), during the water supply to the outer tub 20 , the laundry is easily moved in the above-described manner. Thereby, it is easy to generate mechanical force such as friction between the laundry on the laundry. Therefore, it is possible to wash a large amount of laundry well from the time point of supplying water into the outer tub 20.
<实施方式的效果><Effects of Embodiments>
以上,根据本实施方式,从喷头61的各个喷嘴105喷射的水与洗涤脱水桶24内的上侧的洗涤物接触,因此能通过接触的水的冲击来洗净上侧的洗涤物。由此,即使是在大量的洗涤物被投入洗涤脱水桶24内的情况下,也能降低在洗涤脱水桶24内的上侧的洗涤物与下侧的洗涤物产生的清洗不均匀,能良好地洗净洗涤物。As described above, according to the present embodiment, the water sprayed from the respective nozzles 105 of the head 61 comes into contact with the upper laundry in the washing and dewatering tub 24, so that the upper laundry can be washed by the impact of the contacted water. Thereby, even when a large amount of laundry is put into the washing and dewatering tub 24, the cleaning unevenness of the laundry on the upper side and the laundry in the lower side in the washing and dewatering tub 24 can be reduced, which is good. Wash the laundry.
此外,根据本实施方式,设置为在向外桶20内供水时,从喷头61的各个喷嘴105朝向洗涤脱水桶24内的后侧喷水的同时使波轮26旋转,因而在大量的洗涤物被投入洗涤脱水桶24内的情况下,后侧的洗涤物因为从各个喷嘴105喷射的水的压力等而大幅度下沉,容易与前侧的洗涤物之间产生高度不平衡。而且,当波轮26在这种状态下旋转时,前侧的洗涤物容易向洗涤脱水桶24内的后侧移动。由此,从向外桶20内供水的时间点开始,洗涤物容易以上下互换的方式运动,容易对洗涤物产生洗涤物之间的摩擦等机械力。因此,能从向外桶20内供水的时间点开始良好地洗净大量的洗涤物。Further, according to the present embodiment, it is provided that when the water is supplied into the outer tub 20, the pulsator 26 is rotated while the respective nozzles 105 of the head 61 are sprayed toward the rear side in the washing and dewatering tub 24, and thus a large amount of laundry is washed. When it is put into the washing and dewatering tub 24, the laundry on the rear side is largely sunk by the pressure of the water sprayed from each of the nozzles 105, and the height is unbalanced with the laundry on the front side. Moreover, when the pulsator 26 is rotated in this state, the laundry on the front side is easily moved to the rear side in the washing and dewatering tub 24. Thereby, from the time point of supplying water into the outer tub 20, the laundry is easily moved in the above-described manner, and it is easy to generate mechanical force such as friction between the laundry. Therefore, it is possible to wash a large amount of laundry well from the time point of supplying water into the outer tub 20.
进而,根据本实施方式,喷头61在其长尺寸方向上按规定的间隔设置有多个喷嘴105,因而即使洗涤物与部分喷嘴105接触而堵住喷射口106,喷水的喷嘴105的个数减少也会通过剩余的喷嘴105的水势的增加得到补偿,洗净上侧洗涤物的效果不容易降低。Further, according to the present embodiment, the head 61 is provided with a plurality of nozzles 105 at predetermined intervals in the longitudinal direction. Therefore, even if the laundry contacts the partial nozzles 105 and blocks the ejection openings 106, the number of nozzles 105 for water spray is increased. The reduction is also compensated by the increase in the water potential of the remaining nozzles 105, and the effect of washing the upper side laundry is not easily lowered.
进而,根据本实施方式,在喷头61中,相对于导入口104位于各个喷嘴105的后方,各个喷嘴105的喷射口106朝向斜前方。因此,在喷头61内,即使产生了来自导入口104的水与前侧的壁碰撞并折返而朝向喷射口106这样的水流,也能从喷射口106向喷头61的大致正下位置喷水。因此,能防止以贴着后方的洗涤脱水桶24的内周面侧的方式从各个喷嘴105喷水而导致喷射的水不容易与 洗涤物接触的情况。Further, according to the present embodiment, in the head 61, the injection port 106 of each nozzle 105 faces obliquely forward with respect to the introduction port 104 at the rear of each nozzle 105. Therefore, even if the water from the inlet port 104 collides with the front side wall and is folded back and flows toward the injection port 106, the water can be sprayed from the injection port 106 to the substantially right position of the head 61. Therefore, it is possible to prevent the water sprayed from being ejected from the respective nozzles 105 so as to be in contact with the laundry so as to be in contact with the inner peripheral surface side of the washing dewatering tub 24 at the rear.
进而,根据本实施方式,出自洗涤物并混入水中的线屑、污垢等被过滤器310捕集,因而能防止线屑等进入循环泵62的泵壳体210内、喷头61内,防止线屑等缠在叶轮220上,或者线屑等堵塞喷头61的各个喷嘴105的喷射口106。Further, according to the present embodiment, the lint, dirt, and the like which are taken out from the laundry and mixed in the water are collected by the filter 310, so that it is possible to prevent the lint or the like from entering the inside of the pump casing 210 of the circulation pump 62 and the nozzle 61, and preventing the lint. The impeller 220 is entangled, or the swarf or the like blocks the ejection opening 106 of each nozzle 105 of the head 61.
进而,根据本实施方式,以过滤器壳体320的流出口326与泵壳体210的吸入口211正对的方式,在箱体10内配置有过滤器单元63和循环泵62,并在流出口326与吸入口211之间连接有第二连接管65,因而能以直线状延伸的方式配置第二连接管65。由此,能抑制第二连接管65内的压力损失,能用循环泵62良好地汲取外桶20内的水。Further, according to the present embodiment, the filter unit 63 and the circulation pump 62 are disposed in the casing 10 such that the outflow port 326 of the filter case 320 faces the suction port 211 of the pump casing 210, and is in the flow. The second connecting pipe 65 is connected between the outlet 326 and the suction port 211, so that the second connecting pipe 65 can be arranged to extend linearly. Thereby, the pressure loss in the second connecting pipe 65 can be suppressed, and the water in the outer tub 20 can be satisfactorily captured by the circulation pump 62.
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等的任何限制,此外,本发明的实施方式也可以进行上述以外的各种变更。Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments and the like, and various modifications other than the above may be made in the embodiments of the present invention.
例如,在上述实施方式中,喷水装置60中设置有过滤器单元63。但是,也可以不在喷水装置60中设置过滤器单元63。在这种情况下,第二连接管65将泵壳体210的吸入口211与外桶20的排水口部20c之间连接。需要说明的是,在如上述实施方式所示在喷水装置60中设置有过滤器单元63的情况下,也可以取消设置于洗涤脱水桶24内的线屑过滤器29。在这种情况下,与去掉的线屑过滤器29相应地,洗涤脱水桶24的容积会增加。For example, in the above embodiment, the water spray device 60 is provided with a filter unit 63. However, the filter unit 63 may not be provided in the water spray device 60. In this case, the second connecting pipe 65 connects the suction port 211 of the pump casing 210 and the drain port portion 20c of the outer tub 20. In addition, in the case where the water spray device 60 is provided with the filter unit 63 as described in the above embodiment, the wire filter 29 provided in the washing and dewatering tub 24 may be eliminated. In this case, the volume of the washing and dewatering tub 24 is increased correspondingly to the removed swarf filter 29.
此外,在上述实施方式中,从外桶20内的水位达到泵启动水位而循环泵62开始工作起经过规定时间之后,波轮26开始旋转。但是,也可以在循环泵62开始工作的同时就开始波轮26的旋转。Further, in the above embodiment, the pulsator 26 starts to rotate after a predetermined time elapses from when the water level in the outer tub 20 reaches the pump start water level and the circulation pump 62 starts operating. However, it is also possible to start the rotation of the pulsator 26 while the circulation pump 62 starts operating.
进而,在清洗过程中,也可以设置为如下的洗涤运转模式:在外桶20内蓄水至低水位,使波轮26缓慢旋转,或者使波轮26不旋转而使洗涤脱水桶24缓慢旋转,从喷头61的各个喷嘴105喷水。Further, in the washing process, a washing operation mode may be provided in which the water is stored in the outer tub 20 to a low water level, the pulsator 26 is slowly rotated, or the pulsator 26 is not rotated, and the washing and dewatering tub 24 is slowly rotated. Water is sprayed from each of the nozzles 105 of the head 61.
进而,上述实施方式中,示出了将本发明应用于未搭载衣物的烘干功能的全自动洗衣机1的例子。但是,本发明也能应用于搭载有衣物的烘干功能的全自动洗干一体机。Further, in the above embodiment, an example in which the present invention is applied to the fully automatic washing machine 1 in which the drying function of the laundry is not carried out is shown. However, the present invention can also be applied to a fully automatic washing and drying machine equipped with a drying function of clothes.
除此之外,本发明的实施方式可以在技术方案所示的技术思想的范围内适当地进行各种变更。In addition, the embodiments of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
