Description

排水过滤器及洗衣机Drain filter and washing machine

技术领域Technical field

本发明涉及一种排水过滤器及包括该排水过滤器的洗衣机。The invention relates to a drainage filter and a washing machine including the drainage filter.

背景技术Background technique

下述专利文献1所记载的洗干一体机包括捕获排水中所含的异物的过滤单元。过滤单元具有形成有许多过滤孔的篮(basket)。洗干一体机内的排水下泻至篮内并通过过滤孔，此时，排水中所含的异物被过滤孔捕获而留在篮内。The all-in-one washer-dryer described in Patent Document 1 below includes a filter unit that captures foreign matter contained in the waste water. The filter unit has a basket formed with many filter holes. The drain in the washer-dryer empties into the basket and passes through the filter hole. At this time, the foreign matter contained in the drain is captured by the filter hole and remains in the basket.

在专利文献1所记载的过滤单元中，排水一边下泻一边流入篮内，篮的过滤孔位于排水下泻的去处。因此，排水会在因通过其自重而进行的下落从而增强了水势的状态下通过过滤孔，因此排水中所含的异物容易稳固地缠在过滤孔上。因此，维护时需要时间来去除缠在过滤孔上的异物。In the filter unit described in Patent Document 1, the drained water flows into the basket while falling down, and the filter hole of the basket is located at the place where the drained water drains. Therefore, the drained water passes through the filter hole in a state where the water potential is increased by falling through its own weight, and therefore foreign matter contained in the drained water is easily entangled on the filter hole firmly. Therefore, it takes time to remove foreign matter entangled in the filter holes during maintenance.

发明效果Invention effect

根据本发明，排水过滤器在将排水从入口取入排水空间并从出口排出为止的期间将排水中所含的异物捕获并蓄留于排水空间。入口是形成于第一纵壁的横孔，因此排水会通过以不下落的方式横向流入入口而以不增强水势的方式被取入排水空间。进而，与第一纵壁之间从横向夹着排水空间的第二纵壁上的与入口对置的承接面部从入口承接被取入排水空间的排水，由此减弱排水的水势。由此，排水空间中的排水以减弱了水势的状态在底壁之上流动并从出口排出。因此，排水中所含的异物以不会稳固地缠在排水过滤器的内表面部的方式蓄留于排水空间。因此，用户能在维护时从排水空间轻易取出异物，因此能谋求提高排水过滤器的维护性。According to the present invention, the drainage filter captures and stores the foreign matter contained in the drainage in the drainage space until the drainage is taken into the drainage space from the inlet and discharged from the outlet. The inlet is a horizontal hole formed in the first vertical wall. Therefore, the drainage flows into the inlet laterally without falling, and is taken into the drainage space without increasing the water potential. Furthermore, the receiving surface of the second vertical wall facing the inlet on the second vertical wall sandwiching the drainage space from the lateral direction to the first vertical wall receives the drainage taken into the drainage space from the entrance, thereby reducing the water potential of the drainage. As a result, the drainage in the drainage space flows over the bottom wall in a reduced water potential and is discharged from the outlet. Therefore, the foreign matter contained in the drainage is accumulated in the drainage space so as not to be entangled firmly on the inner surface of the drainage filter. Therefore, the user can easily take out foreign objects from the drainage space during maintenance, and therefore it is possible to improve the maintainability of the drainage filter.

此外，根据本发明，横向流入入口而被取入排水空间并被承接面部减弱了水势的排水会在底壁上比入口靠下游侧的下游部分之上流动，从第一纵壁和第二纵壁各自的各梳齿的周围的出口排出。减弱了水势的排水中所含的异物以不会稳固地缠在梳齿上的方式蓄留于排水空间。因此，用户能在维护时从排水空间轻易取出异物，因此能谋求提高排水过滤器的维护性。In addition, according to the present invention, the drainage that flows laterally into the inlet and is taken into the drainage space and is weakened by the receiving surface will flow on the bottom wall on the downstream part downstream of the inlet, from the first vertical wall and the second vertical wall. The outlets around the respective comb teeth of the walls are discharged. The foreign matter contained in the drain whose water potential is weakened is stored in the drain space so as not to be firmly entangled with the comb teeth. Therefore, the user can easily take out foreign objects from the drainage space during maintenance, and therefore it is possible to improve the maintainability of the drainage filter.

此外，根据本发明，底壁的下游部分按照距离入口从近到远的顺序具有上游区域、中途区域以及下游区域，上游区域和下游区域在底壁的短尺寸方向上比中途区域宽。由此，从入口被取入排水空间并在下游部分之上流动的排水不仅能立即在上游区域从出口排出，还能来到中途区域、下游区域从出口排出。因此，能防止蓄留在排水空间的异物因偏倚地留在底壁的下游部分的上游区域而缠在上游区域附近的梳齿上。因此，用户能在维护时从排水空间轻易取出异物，因此能谋求提高排水过滤器的维护性。In addition, according to the present invention, the downstream portion of the bottom wall has an upstream area, a midway area, and a downstream area in order from near to far from the entrance, and the upstream area and the downstream area are wider than the midway area in the short dimension of the bottom wall. As a result, the drainage that is taken into the drainage space from the inlet and flows over the downstream portion can not only be immediately discharged from the outlet in the upstream area, but can also be discharged from the outlet in the intermediate area and downstream area. Therefore, it is possible to prevent foreign matter accumulated in the drainage space from being eccentrically left in the upstream region of the downstream portion of the bottom wall and entangled with the comb teeth in the vicinity of the upstream region. Therefore, the user can easily take out foreign objects from the drainage space during maintenance, and therefore it is possible to improve the maintainability of the drainage filter.

A take-out port 20A is formed at one end of the circulation path 20, and a return port 20B is formed at one end of the circulation path 20. The take-out port 20A is connected to a part of the back wall 3B of the outer cylinder 3 that is higher than the upper limit water level in the outer cylinder 3, and communicates with the outer cylinder 3 from the rear side Y2. The return port 20B is connected to the upper end of the second part 3F of the front wall 3C of the outer tube 3 and communicates with the inner tube 3 from the upper side Z1.

送风部21是所谓的鼓风机，包括配置在循环路20内的旋转叶片23和使旋转叶片23旋转的马达(未图示)。当旋转叶片23旋转时，如粗虚线箭头所示，洗涤筒13内的空气也就是外筒3内和内筒7内的空气从取出口20A被取出至循环路20内，然后从返回口20B返回至洗涤筒13内。由此，洗涤筒13内的空气以按顺序流过洗涤筒13和循环路20的方式循环。The blower 21 is a so-called blower, and includes a rotating blade 23 arranged in the circulation path 20 and a motor (not shown) that rotates the rotating blade 23. When the rotating blade 23 rotates, as shown by the thick dashed arrow, the air in the washing tub 13, that is, the air in the outer tub 3 and the inner tub 7 is taken out from the outlet 20A to the circulation path 20, and then from the return port 20B Return to the washing tub 13. Thereby, the air in the washing tub 13 circulates so as to flow through the washing tub 13 and the circulation path 20 in order.

加热部22是热泵中的热交换器或普通的加热器等，至少一部分设于循环路20内。加热部22中的设于循环路20内的部分具有多个例如翅片状的散热部22A。当加热部22工作时，散热部22A变为高温，因此在循环路20内流动的空气在通过散热部22A的周围时会被加热而成为热风。The heating unit 22 is a heat exchanger in a heat pump, a general heater, or the like, and at least a part is provided in the circulation path 20. A part of the heating part 22 provided in the circulation path 20 has a plurality of fin-shaped heat dissipation parts 22A, for example. When the heating part 22 is operated, the heat dissipation part 22A becomes high temperature, so the air flowing in the circulation path 20 is heated when passing around the heat dissipation part 22A and becomes hot air.

洗衣机1包括配置为微型计算机的控制部24。控制部24通过控制马达8、供水阀11、排水阀12、送风部21以及加热部22的动作来执行洗涤运转。洗涤运转包括清洗过程、漂洗过程、脱水过程以及烘干过程。The washing machine 1 includes a control section 24 configured as a microcomputer. The control unit 24 executes the washing operation by controlling the operation of the motor 8, the water supply valve 11, the drain valve 12, the air blowing unit 21, and the heating unit 22. The washing operation includes a cleaning process, a rinsing process, a dehydration process, and a drying process.

在清洗过程开始之前，将洗涤剂投入内筒7内。在清洗过程中，控制部24在关闭排水阀12的状态下打开供水阀11规定时间而向外筒3和内筒7供水，然后利用马达8使内筒7旋转。由此，内筒7内的洗涤物L被捶洗。在捶洗中，洗涤物L反复进行被举起一定程度后自然下落至水面这样的翻滚。利用翻滚所产生的冲击、蓄留于内筒7的水中所含的洗涤剂成分，从洗涤物L去除污渍。当从翻滚开始经过规定时间后控制部24打开排水阀12进行排水时，清洗过程结束。Before the cleaning process starts, the detergent is put into the inner cylinder 7. During the cleaning process, the control unit 24 opens the water supply valve 11 for a predetermined time with the drain valve 12 closed to supply water to the outer tube 3 and the inner tube 7, and then uses the motor 8 to rotate the inner tube 7. As a result, the laundry L in the inner tub 7 is beaten and washed. In the pounding washing, the laundry L is repeatedly lifted to a certain extent and then falls naturally to the surface of the water. The detergent component contained in the water stored in the inner cylinder 7 is used to remove stains from the laundry L by the impact generated by the tumbling. When a predetermined time has elapsed from the start of the roll, the control unit 24 opens the drain valve 12 to drain water, and the washing process ends.

在漂洗过程中，控制部24在关闭排水阀12的状态下打开供水阀11规定时间而向外筒3和内筒7供水，然后利用马达8使内筒7旋转。然后，反复进行上述的翻滚，因此洗涤物L被内筒7内的自来水漂洗。当从翻滚开始经过规定时间后控制部24进行排水时，漂洗过程结束。漂洗过程可以反复进行多次。在脱水过程中，控制部24在打开排水阀12的状态下使内筒7进行脱水旋转。利用由内筒7的脱水旋转产生的离心力，内筒7内的洗涤物L被脱水。通过脱水而从洗涤物L渗出的水从排水路5排出至机外。脱水过程不仅可以在漂洗过程后实施，也可以在清洗过程后也实施。During the rinsing process, the control unit 24 opens the water supply valve 11 for a predetermined time with the drain valve 12 closed to supply water to the outer tube 3 and the inner tube 7, and then uses the motor 8 to rotate the inner tube 7. Then, the tumbling described above is repeated, and therefore, the laundry L is rinsed by the tap water in the inner tub 7. When a predetermined time has elapsed from the start of tumbling, the control unit 24 drains water, the rinsing process ends. The rinsing process can be repeated many times. During the dehydration process, the control unit 24 causes the inner cylinder 7 to spin dehydration while the drain valve 12 is opened. The laundry L in the inner tub 7 is dehydrated by the centrifugal force generated by the dehydration rotation of the inner tub 7. The water seeping out from the laundry L due to dehydration is discharged from the drain 5 to the outside of the machine. The dehydration process can be implemented not only after the rinsing process, but also after the washing process.

在烘干过程中，控制部24利用送风部21和加热部22产生热风并使其在内筒7与循环路20之间循环，将热风供给至内筒7内的洗涤物L。由此，洗涤物L被烘干。需要说明的是，洗衣机1可以是省略了烘干部9的洗衣机，在该情况的洗涤运转中，省略烘干过程。During the drying process, the control unit 24 uses the air blowing unit 21 and the heating unit 22 to generate hot air and circulate it between the inner tube 7 and the circulation path 20 to supply the hot air to the laundry L in the inner tube 7. Thus, the laundry L is dried. It should be noted that the washing machine 1 may be a washing machine in which the drying unit 9 is omitted. In this case, the drying process is omitted during the washing operation.

承接部31的内部空间31C的前端部作为圆形的出入口31D从箱体2的前表面2A露出。需要说明的是，在前表面2A设有可开闭的门(未图示)，普通的出入口31D可以从前侧Y1被闭位置的门覆盖。在承接部31中的划分出出入口31D的内周面的中途，以在前后方向Y上排列的方式设有圆环状的第一台阶部31E和第二台阶部31F。第一台阶部31E比第二台阶部31F直径小，配置于第二台阶部31F的后侧Y2。承接部31的内周面的比第二台阶部31F靠前侧Y1的前区域的直径比第二台阶部31F大。在该前区域设有在其周向上延伸的锁定爪31G。锁定爪31G设有多个，在该情况下配置为在承接部31的内周面的周向上排列。The front end portion of the internal space 31C of the receiving portion 31 is exposed from the front surface 2A of the box 2 as a circular port 31D. It should be noted that an openable and closable door (not shown) is provided on the front surface 2A, and the ordinary entrance and exit 31D can be covered by the door at the closed position from the front side Y1. In the middle of the inner peripheral surface of the receiving portion 31 that divides the port 31D, an annular first step portion 31E and a second step portion 31F are provided so as to be aligned in the front-rear direction Y. The first step portion 31E has a smaller diameter than the second step portion 31F, and is arranged on the rear side Y2 of the second step portion 31F. The diameter of the front region of the inner peripheral surface of the receiving portion 31 that is closer to the front side Y1 than the second step portion 31F is larger than that of the second step portion 31F. In this front area, a locking claw 31G extending in the circumferential direction is provided. A plurality of locking pawls 31G are provided, and in this case, they are arranged so as to be lined up in the circumferential direction of the inner peripheral surface of the receiving portion 31.

接着，对排水过滤器6向承接部31的拆装进行说明。在装接排水过滤器6的情况下，首先，用户抓住排水过滤器6的容纳部32的操作部33中的把手33B来使容纳部32移动至承接部31的出入口31D的前侧Y1。表示装接时的排水过滤器6的姿势的标志M1设于容纳部32等(参照图4)，因此用户以使容纳部32的排水空间46向上侧Z1敞开的方式根据需要来矫正排水过滤器6的姿势。然后，用户使容纳部32向后侧Y2移动，从容纳部32侧***至出入口31D。如此，容纳部32穿过出入口31D而被容纳向承接部31的内部空间31C。Next, the attachment and detachment of the drainage filter 6 to the receiving portion 31 will be described. In the case of attaching the drain filter 6, first, the user grasps the handle 33B in the operating portion 33 of the accommodating portion 32 of the drain filter 6 to move the accommodating portion 32 to the front side Y1 of the inlet and outlet 31D of the receiving portion 31. The mark M1 indicating the posture of the drainage filter 6 at the time of attachment is provided in the accommodating portion 32 and the like (refer to FIG. 4). Therefore, the user corrects the drainage filter as needed by opening the drainage space 46 of the accommodating portion 32 to the upper side Z1. 6 posture. Then, the user moves the accommodating portion 32 to the rear side Y2, and inserts it from the side of the accommodating portion 32 to the entrance 31D. In this way, the accommodating portion 32 passes through the entrance 31D and is accommodated in the internal space 31C of the receiving portion 31.

然后，当容纳部32的前壁45的垫圈52如图8所示从前侧Y1与容纳部32的出入口31D中的第一台阶部31E接触时，整个容纳部32容纳于承接部31的内部空间31C，由此排水过滤器6向承接部31也就是洗衣机1的装接完成。在该状态下，承接部31的内部空间31C被前壁45从前侧Y1堵住，容纳部32的第一台阶部31E和第二台阶部31F各自与前壁45的间隙被垫圈52堵住。接着，用户抓住操作部33中的把手33B将其扭转来使操作部33转动。由此，当出入口31D内的锁定爪31G进入操作部33的圆盘部33A的锁定槽33C时，操作部33在前后方向Y上无法移动，因此排水过滤器6以被装接于承接部31的状态被锁定。需要说明的是，表示操作部33的转动方向的标志M2设于操作部33等(参照图2)，因此用户参考该标志M2来使操作部33转动。Then, when the gasket 52 of the front wall 45 of the accommodating portion 32 contacts the first step portion 31E in the entrance 31D of the accommodating portion 32 from the front side Y1 as shown in FIG. 8, the entire accommodating portion 32 is accommodated in the internal space of the receiving portion 31 31C, as a result, the attachment of the drain filter 6 to the receiving portion 31, that is, the washing machine 1 is completed. In this state, the internal space 31C of the receiving portion 31 is blocked by the front wall 45 from the front side Y1, and the gap between the first step portion 31E and the second step portion 31F of the accommodating portion 32 and the front wall 45 is blocked by the gasket 52. Next, the user grasps the handle 33B in the operation part 33 and twists it to rotate the operation part 33. Thus, when the locking claw 31G in the entrance 31D enters the locking groove 33C of the disc portion 33A of the operating portion 33, the operating portion 33 cannot move in the front-rear direction Y, so the drain filter 6 is attached to the receiving portion 31 The status is locked. It should be noted that the mark M2 indicating the direction of rotation of the operation section 33 is provided on the operation section 33 and the like (refer to FIG. 2 ), so the user refers to the mark M2 to rotate the operation section 33.

在装接于承接部31的排水过滤器6中，容纳部32配置于承接部31的内部空间31C也就是排水路5内。需要说明的是，容纳部32的后端部可以从内部空间31C向后侧Y2露出而被纳入排水路5的下游排水路5B内。排水路5内的容纳部32配置为与承接部31的倾斜对应地以随着靠近后侧Y2而下降的方式相对于水平方向H倾斜。此外，容纳部32的左壁42的入口51从右侧X2与承接部31的流入部31B的内部空间对置。In the drainage filter 6 attached to the receiving portion 31, the accommodating portion 32 is arranged in the internal space 31C of the receiving portion 31, that is, in the drainage channel 5. It should be noted that the rear end portion of the accommodating portion 32 may be exposed to the rear side Y2 from the internal space 31C and be included in the downstream drainage channel 5B of the drainage channel 5. The accommodating portion 32 in the drainage channel 5 is arranged to be inclined with respect to the horizontal direction H so as to descend toward the rear side Y2 in accordance with the inclination of the receiving portion 31. As shown in FIG. In addition, the entrance 51 of the left wall 42 of the accommodating portion 32 faces the internal space of the inflow portion 31B of the receiving portion 31 from the right side X2.

在排水过滤器6被装接于承接部31的状态下，洗衣机1执行洗涤运转，当此时打开排水阀12时，从洗涤筒13流向排水路5的排水向右侧X2横向流过承接部31的流入部31B和容纳部32的左壁42的入口51，从入口51被取入排水过滤器6的容纳部32的排水空间46，紧接着与容纳部32的右壁43的承接面部43B(参照图8的粗虚线箭头W1)碰撞。也就是说，承接面部43B承接刚从入口51被取入排水空间46的排水。由此，流入排水空间46的排水会改变流向而在排水空间46中按顺序向后侧Y2流过底壁41的上游部分47和下游部分48(参照图8的粗虚线箭头W2)。如此，排水空间46构成排水的流路。此外，在底壁41中，至少下游部分48在排水空间46内的排水的流动方向上位于比入口51靠下游侧也就是后侧Y2。With the drain filter 6 attached to the receiving portion 31, the washing machine 1 performs washing operation. When the drain valve 12 is opened at this time, the drain flowing from the washing tub 13 to the drain path 5 flows laterally through the receiving portion X2 to the right The inflow portion 31B of 31 and the entrance 51 of the left wall 42 of the accommodating portion 32 are taken into the drainage space 46 of the accommodating portion 32 of the drainage filter 6 from the entrance 51, and are next to the receiving surface 43B of the right wall 43 of the accommodating portion 32 (Refer to the thick dashed arrow W1 in FIG. 8) collision. In other words, the receiving surface 43B receives the drain water that has just been taken into the drain space 46 from the inlet 51. As a result, the drainage flowing into the drainage space 46 changes its flow direction and flows through the upstream portion 47 and the downstream portion 48 of the bottom wall 41 in order to the rear side Y2 in the drainage space 46 (refer to the thick dashed arrow W2 in FIG. 8). In this way, the drainage space 46 constitutes a drainage channel. In addition, in the bottom wall 41, at least the downstream portion 48 is located on the downstream side than the inlet 51, that is, the rear side Y2, in the flow direction of the drainage in the drainage space 46.

向后侧Y2流过排水空间46的排水在穿过任一出口53从而从排水空间46排出后(参照图4的粗虚线箭头W3、W4以及W5)，向后侧Y2流过承接部31的内部空间31C而流入排水路5的下游排水路5B，最终被排出机外。虽然流过排水过滤器6中的排水空间46的排水穿过出口53从排水空间46排出，但排水中所含的线头、头发等长条状的异物F会被梳齿42D、梳齿43C以及梳齿44C阻挡，由此无法通过出口53而会蓄留于排水空间46，在排水空间46的后部汇集成柔软的块状(参照图4)。如此，排水过滤器6捕获排水中所含的异物F。The drainage flowing through the drainage space 46 to the rear side Y2 passes through any outlet 53 and is discharged from the drainage space 46 (refer to the thick dashed arrows W3, W4, and W5 in FIG. 4), and then flows to the rear side Y2 through the receiving portion 31 The internal space 31C flows into the downstream drainage channel 5B of the drainage channel 5, and is finally discharged out of the machine. Although the drainage flowing through the drainage space 46 in the drainage filter 6 is discharged from the drainage space 46 through the outlet 53, the long foreign matter F such as thread and hair contained in the drainage will be caught by the comb teeth 42D, comb teeth 43C and Since the comb teeth 44C are blocked, they cannot pass through the outlet 53 and are stored in the drainage space 46, and gather into a soft block shape at the rear part of the drainage space 46 (refer to FIG. 4). In this way, the drainage filter 6 captures the foreign matter F contained in the drainage.

在装接于承接部31的排水过滤器6中，把手33B从箱体2的前表面2A露出。在为了进行维护等而使排水过滤器6脱离情况下，首先，用户抓住把手33B而使操作部33朝与装接时相反的方向转动。由此，出入口31D内的锁定爪31G会脱离操作部33的圆盘部33A的锁定槽33C，因此排水过滤器6的锁定被解除，操作部33能在前后方向Y上移动。接着，用户抓住把手33B向前侧Y1拉动，由此使容纳部32向前侧Y1移动。然后，当将整个容纳部32拉出至比承接部31的出入口31D靠前侧Y1时，排水过滤器6从承接部31的脱离完成。In the drainage filter 6 attached to the receiving portion 31, the handle 33B is exposed from the front surface 2A of the box 2. When the drain filter 6 is detached for maintenance or the like, first, the user grasps the handle 33B and rotates the operation portion 33 in the direction opposite to that at the time of attachment. As a result, the lock claw 31G in the port 31D disengages from the lock groove 33C of the disc portion 33A of the operation portion 33, so the lock of the drain filter 6 is released, and the operation portion 33 can move in the front-rear direction Y. Next, the user grasps the handle 33B and pulls it to the front side Y1, thereby moving the accommodating portion 32 to the front side Y1. Then, when the entire accommodating portion 32 is pulled out to the front side Y1 than the entrance and exit 31D of the receiving portion 31, the detachment of the drainage filter 6 from the receiving portion 31 is completed.

如上所述，排水过滤器6在将排水从入口51取入排水空间46并从出口53排出为止的期间，将排水中所含的异物F捕获并蓄留于排水空间46。入口51 是形成于左壁42的横孔，因此排水会通过以不下落的方式横向流入入口51而以不增强水势的方式被取入排水空间46。进而，与左壁42之间从横向夹着排水空间46的右壁43上的与入口51对置的承接面部43B从入口51承接被取入排水空间46的排水(参照图8的粗虚线箭头W1)，由此减弱排水的水势。由此，排水空间46中的排水以减弱了水势的状态在底壁41的下游部分48之上流动并从出口53排出(参照图8的粗虚线箭头W2)。As described above, the drainage filter 6 captures and stores the foreign matter F contained in the drainage in the drainage space 46 until the drainage is taken into the drainage space 46 from the inlet 51 and discharged from the outlet 53. The inlet 51 is a horizontal hole formed in the left wall 42, and therefore, the drain is taken into the drainage space 46 without increasing the water potential by flowing laterally into the inlet 51 without falling. Furthermore, the receiving surface 43B on the right wall 43 facing the inlet 51 on the right wall 43 sandwiching the drain space 46 from the left wall 42 from the inlet 51 receives the drain taken into the drain space 46 from the inlet 51 (refer to the thick dashed arrow in FIG. 8 W1), thereby reducing the water potential of the drainage. Thereby, the drainage in the drainage space 46 flows over the downstream portion 48 of the bottom wall 41 in a state where the water potential is weakened, and is discharged from the outlet 53 (refer to the thick broken line arrow W2 in FIG. 8).

因此，排水中所含的异物F以不稳固地缠在排水过滤器6的内表面部(具体而言梳齿42D、梳齿43C、梳齿44D)的方式成为上述的柔软的块状并蓄留于排水空间46(参照图4)。因此，用户在维护时只要抓住已脱离的排水过滤器6的操作部33的把手33B并如图9所示以使排水空间46向下侧Z2敞开的方式将排水过滤器6往下扯，就能利用这一势头使排水空间46内的异物F的团块干净地下落。即使存在未下落而残留于排水空间46的异物F，通过使容纳部32暴露在流水中，也能从排水空间46顺利地去除该异物F。由此，能从排水空间46轻易取出异物F，因此能谋求提高排水过滤器6的维护性。此外，用户即使不接触梳齿42D、梳齿43C、梳齿44D也能从排水空间46取出异物F，因此能防止用户在维护时施加过大的力而折断这些梳齿的不良情况。Therefore, the foreign matter F contained in the drainage becomes the above-mentioned soft lump and accumulates in such a way that it is unsteadily entangled on the inner surface of the drainage filter 6 (specifically, the comb teeth 42D, the comb teeth 43C, and the comb teeth 44D). Leave it in the drainage space 46 (refer to FIG. 4). Therefore, the user only needs to grasp the handle 33B of the operating part 33 of the separated drainage filter 6 during maintenance and pull the drainage filter 6 downward in such a way that the drainage space 46 is opened to the lower side Z2 as shown in FIG. 9. This momentum can be used to make the clumps of foreign matter F in the drainage space 46 fall cleanly. Even if there is a foreign matter F remaining in the drainage space 46 without falling, the foreign matter F can be smoothly removed from the drainage space 46 by exposing the accommodating portion 32 to running water. As a result, the foreign matter F can be easily taken out from the drainage space 46, and therefore, the maintainability of the drainage filter 6 can be improved. In addition, the user can take out the foreign matter F from the drainage space 46 without touching the

comb teeth

42D, 43C, and comb teeth 44D. Therefore, it is possible to prevent the user from applying excessive force during maintenance to break the comb teeth.

此外，底壁41的下游部分按照离入口51从近到远的顺序具有上游区域48A、中途区域48B以及下游区域48C，上游区域48A和下游区域48C在作为底壁41的短尺寸方向的左右方向X上比中途区域48B宽(参照图4)。由此，不仅能将从入口51被取入排水空间46并在下游部分48之上流动的排水紧接着在上游区域48A从出口53排出，还能使该排水来到中途区域48B、下游区域48C并从出口53排出(参照图4的粗虚线箭头W3)。因此，能防止蓄留在排水空间46的异物F因偏倚地留在底壁41的下游部分48中的上游区域48A而缠在上游区域48A附近的梳齿42D、梳齿43C上。因此，用户能在维护时从排水空间46顺利地取出异物F，因此能谋求提高排水过滤器6的维护性。In addition, the downstream portion of the bottom wall 41 has an upstream region 48A, a midway region 48B, and a downstream region 48C in order from nearer to farthest from the inlet 51. The upstream region 48A and the downstream region 48C are in the left-right direction as the short dimension direction of the bottom wall 41. X is wider than midway area 48B (refer to FIG. 4). As a result, not only the drainage taken into the drainage space 46 from the inlet 51 and flowing over the downstream portion 48 can be discharged from the outlet 53 in the upstream area 48A, but also the drainage can be brought to the midway area 48B and the downstream area 48C. And it is discharged from the outlet 53 (refer to the thick dotted arrow W3 in FIG. 4). Therefore, the foreign matter F accumulated in the drainage space 46 can be prevented from being eccentrically left in the upstream region 48A in the downstream portion 48 of the bottom wall 41 and entangled with the comb teeth 42D and the comb teeth 43C near the upstream region 48A. Therefore, the user can smoothly take out the foreign matter F from the drain space 46 during maintenance, and therefore it is possible to improve the maintainability of the drain filter 6.

In this case, the comb teeth at each outlet 53 can be regarded as a part of the bottom wall 41. The part located around the lower end of each of the comb teeth 42D, the comb teeth 43C, and the comb teeth 44D is regarded as an outlet 53 formed in the bottom wall 41 (refer to FIG. 4).
