发明效果Invention effect
根据本发明,在洗干一体机的烘干运转中,通过送风部进行动作,洗涤筒内的空气以从取出口取出至循环路内并从返回口返回至洗涤筒内的方式进行循环。循环的空气通过被加热部加热而成为热风,将洗涤筒内的洗涤物烘干。具有构成循环路的一部分的容器的滤水器在容器内蓄有水的情况下,使为了循环而在循环路内从取出口前往返回口的空气在容器内的水中通过,由此从该空气中捕获异物而蓄留于容器内。在该情况下,如果将容器内的水倒掉,则蓄留于容器内的异物也随着水被排出,因此能容易地维护滤水器。因此,能谋求关于烘干运转的使用方便性的提高。According to the present invention, during the drying operation of the integrated washer-dryer, the air blower operates, and the air in the washing tub is circulated so as to be taken out from the outlet to the circulation path and returned to the washing tub from the return port. The circulating air is heated by the heating part to become hot air, and the laundry in the washing tub is dried. When a water filter with a container constituting a part of the circulation path contains water in the container, the air from the outlet to the return port in the circulation path for circulation passes through the water in the container, thereby removing the air The foreign matter is captured in the medium and stored in the container. In this case, if the water in the container is poured, the foreign matter stored in the container is also discharged with the water, so the water filter can be easily maintained. Therefore, it is possible to improve the usability of the drying operation.
不过,在烘干运转中空气以始终通过容器内的水的方式进行循环的情况下,容器内的水成为阻力,由此空气的循环恐怕会逐渐变弱。另一方面,在检测在烘干运转中循环的空气的温度或温度变化量的温度传感器的检测值小于第一阈值的情况下,循环的低温的空气所含有的尘埃、线头等异物少至不需要利用滤水器立即捕获的程度。相反,在温度传感器的检测值为比第一阈值高的第二阈值以上的情况下,在循环的高温的空气中含有的异物多至需要利用滤水器立即捕获的程度。However, when air circulates so as to always pass through the water in the container during the drying operation, the water in the container becomes resistance, and the circulation of air may gradually become weaker. On the other hand, when the detection value of the temperature sensor that detects the temperature or the amount of temperature change of the air circulating during the drying operation is less than the first threshold, the circulating low-temperature air contains as little as no foreign matter such as dust and lint. Need to use the water filter to capture the degree immediately. Conversely, when the detection value of the temperature sensor is greater than the second threshold value higher than the first threshold value, the circulating high-temperature air contains as many foreign matters as it needs to be immediately captured by the water filter.
因此,在洗干一体机中执行洗涤运转的控制部,在烘干运转中的温度传感器的检测值小于第一阈值的情况下,即不需要利用滤水器从循环中的空气中捕获异物的情况下,控制循环路内的空气的流动,使空气以不通过容器内的水的方式进行循环。另一方面,在烘干运转中的温度传感器的检测值为第二阈值以 上的情况下,即在需要利用滤水器从循环中的空气中捕获异物的情况下,控制部控制循环路内的空气的流动,使空气以通过容器内的水的方式进行循环,由此从循环的空气中捕获异物。Therefore, in the control unit that executes the washing operation in the washer-dryer, if the temperature sensor detection value during the drying operation is less than the first threshold, that is, there is no need to use a water filter to capture foreign matter from the circulating air. In this case, the flow of air in the circulation path is controlled so that the air is circulated without passing through the water in the container. On the other hand, when the detection value of the temperature sensor during the drying operation is greater than or equal to the second threshold, that is, when the water filter needs to be used to capture foreign matter from the circulating air, the control unit controls the The flow of air causes the air to circulate by passing through the water in the container, thereby capturing foreign matter from the circulating air.
如此,在烘干运转中,控制部仅在需要从循环的空气中捕获异物时使该空气在容器内的水中通过,在不需要捕获异物时使该空气不通过容器内的水。在该情况下,与始终使循环的空气在容器内的水中通过的情况相比,能在整个烘干运转中使烘干用的空气顺畅地循环,因此能抑制烘干性能的降低。In this way, during the drying operation, the control unit allows the air to pass through the water in the container only when foreign matter needs to be captured from the circulating air, and prevents the air from passing through the water in the container when foreign matter does not need to be captured. In this case, as compared with the case where the circulating air is always passed through the water in the container, the air for drying can be circulated smoothly throughout the drying operation, and therefore the reduction in drying performance can be suppressed.
此外,根据本发明,循环路配置为在分支为绕过了滤水器的容器的第一支路和与容器相连的第二支路之后汇合,切换部以使循环路内的空气流过第一支路和第二支路中的任一方的方式对循环路内的空气的流动进行切换。在这样的构成中,当烘干运转中的温度传感器的检测值小于第一阈值,即不需要利用滤水器从循环中的空气中捕获异物时,控制部通过控制切换部,以使循环路内的空气流过第一支路的方式对循环路内的空气的流动进行切换,因此空气以不通过容器内的水的方式进行循环。另一方面,当烘干运转中的温度传感器的检测值为第二阈值以上,即产生利用滤水器从循环中的空气中捕获异物的需要时,控制部通过控制切换部,以使循环路内的空气流过第二支路的方式对循环路内的空气的流动进行切换,因此空气以通过容器内的水的方式进行循环。通过由这样的控制部实现的切换部的控制,在烘干运转中,能仅在需要从循环的空气中捕获异物时使该空气在容器内的水中通过,在不需要捕获异物时不使该空气在容器内的水中通过。In addition, according to the present invention, the circulation path is configured to merge after the first branch path branching into the container bypassing the water filter and the second branch path connected to the container, and the switching part is configured to allow the air in the circulation path to flow through the second branch path. The flow of air in the circulation path is switched by either one of the branch path or the second branch path. In such a configuration, when the detection value of the temperature sensor during the drying operation is less than the first threshold, that is, when there is no need to use a water filter to capture foreign matter from the circulating air, the control unit controls the switching unit to make the circulation path The way the air inside flows through the first branch switches the flow of the air in the circulation path, so the air circulates so as not to pass through the water in the container. On the other hand, when the detection value of the temperature sensor during the drying operation is greater than the second threshold, that is, when the need to capture foreign objects from the circulating air by the water filter, the control unit controls the switching unit to make the circulation path The way in which the air inside flows through the second branch switches the flow of the air in the circulation path, so the air circulates by passing through the water in the container. Through the control of the switching unit realized by such a control unit, in the drying operation, the air can pass through the water in the container only when the foreign matter needs to be captured from the circulating air, and the foreign matter is not allowed to be captured when the foreign matter does not need to be captured. Air passes through the water in the container.
此外,根据本发明,控制部在关闭了流出阀的状态下打开流入阀,使水从流入路向容器内流入,由此能在容器内蓄水,打开流出阀而使容器内的水从流出路流出,由此能排空容器。在这样的构成中,当烘干运转中的温度传感器的检测值小于第一阈值,即不需要利用滤水器从循环中的空气中捕获异物时,控制部通过控制流入阀和流出阀中的至少任一方的开闭而排空容器,因此循环的空气在容器内不通过水而流动。另一方面,当烘干运转中的温度传感器的检测值为第二阈值以上,即产生利用滤水器从循环中的空气中捕获异物的需要时,控制部通过控制流入阀和流出阀中的至少任一方的开闭而在容器内蓄水,因此空气以通过容器内的水的方式进行循环。通过由这样的控制部实现的流入阀、 流出阀的控制,在烘干运转中,能仅在需要从循环的空气中捕获异物时在容器内蓄水并使该空气在容器内的水中通过,在不需要捕获异物时排空容器使该空气在容器内不受水的阻力而顺畅地流动。In addition, according to the present invention, the control unit opens the inflow valve with the outflow valve closed to allow water to flow into the container from the inflow path, thereby storing water in the container and opening the outflow valve to allow the water in the container to flow from the outflow path. Flow out, thereby allowing the container to be emptied. In such a configuration, when the detection value of the temperature sensor during the drying operation is less than the first threshold, that is, when there is no need to use a water filter to capture foreign matter from the circulating air, the control unit controls the inflow and outflow valves. At least any one of them is opened and closed to empty the container, so the circulating air does not flow through the water in the container. On the other hand, when the detection value of the temperature sensor during the drying operation is higher than the second threshold, that is, when the need to capture foreign matter from the circulating air using the water filter, the control unit controls the inflow valve and the outflow valve. Opening and closing of at least one of them stores water in the container, so air circulates through the water in the container. By controlling the inflow valve and the outflow valve by such a control unit, in the drying operation, it is possible to store water in the container and allow the air to pass through the water in the container only when foreign matter needs to be captured from the circulating air. Emptying the container when there is no need to capture foreign matter allows the air to flow smoothly in the container without the resistance of water.
此外,根据本发明,在烘干运转中的温度传感器的检测值为第一阈值以上且小于第二阈值的状态持续规定时间的情况下,恐怕会在循环的空气中开始产生异物。因此,控制部控制循环路内的空气的流动,使空气以通过容器内的水的方式进行循环,因此能利用滤水器将在循环的空气中开始产生的异物立即捕获。In addition, according to the present invention, when the detection value of the temperature sensor during the drying operation is greater than or equal to the first threshold value and less than the second threshold value for a predetermined period of time, there is a possibility that foreign matter may start to be generated in the circulating air. Therefore, the control unit controls the flow of the air in the circulation path and circulates the air by passing through the water in the container. Therefore, the water filter can immediately capture foreign matter that begins to be generated in the circulating air.
此外,根据本发明,在烘干运转中的温度传感器的检测值从第二阈值以上降低至小于第一阈值的情况下,视为循环的空气中的异物减少至不需要捕获的程度。因此,控制部控制循环路内的空气的流动,使空气以不通过容器内的水的方式进行循环。由此,在该状态的烘干运转中,能使烘干用的空气顺畅地循环,因此能抑制烘干性能的降低。In addition, according to the present invention, when the detection value of the temperature sensor in the drying operation decreases from the second threshold or more to less than the first threshold, the foreign matter in the circulating air is reduced to the extent that it does not need to be captured. Therefore, the control unit controls the flow of air in the circulation path so that the air circulates without passing through the water in the container. Thereby, in the drying operation in this state, the air for drying can be circulated smoothly, and therefore, the reduction in drying performance can be suppressed.

When the control unit 60 opens the outflow valve 34, the water in the container 40 flows out to the outflow path 33, and is discharged to the outside of the machine through the drain path 5. The control unit 60 controls the opening and closing of the switching unit 36 so that the air taken out from the outlet 20D into the first portion 20BA of the circulation path 20 flows through either the first branch 20BD and the second branch 20BE.
水位传感器61是检测滤水器30的容器40内的水位的公知的传感器,例如安装于容器40中的连接有溢水路35的部分的附近。水位传感器61的检测值被实时输入至控制部60。The water level sensor 61 is a well-known sensor that detects the water level in the container 40 of the water filter 30, and is installed, for example, in the vicinity of the portion of the container 40 to which the overflow path 35 is connected. The detection value of the water level sensor 61 is input to the control unit 60 in real time.
作为温度传感器62,能使用公知的温度传感器。温度传感器62例如安装于洗涤筒3。温度传感器62通过检测洗涤筒3内的空气的温度,检测与送风部21的工作相应地循环的空气的温度。需要说明的是,温度传感器62也可以不将循环的空气的温度本身作为检测值来检测,而是将相对于规定的基准温度的该空气的温度变化量作为检测值来检测。温度传感器62的检测值被实时输入至控制部60。As the temperature sensor 62, a well-known temperature sensor can be used. The temperature sensor 62 is attached to the washing tub 3, for example. The temperature sensor 62 detects the temperature of the air in the washing tub 3 and detects the temperature of the air circulated in accordance with the operation of the blower 21. It should be noted that the temperature sensor 62 may not detect the temperature of the circulating air itself as a detection value, but may detect the temperature change amount of the air relative to a predetermined reference temperature as a detection value. The detection value of the temperature sensor 62 is input to the control unit 60 in real time.
控制部60使马达8工作而分别使供水阀12和排水阀13开闭,由此依次执行清洗运转、漂洗运转以及脱水运转。漂洗运转可执行多次,脱水运转可以在清洗运转与漂洗运转之间、漂洗运转与下一次漂洗运转之间执行。The control unit 60 operates the motor 8 to open and close the water supply valve 12 and the drain valve 13 respectively, thereby sequentially performing a washing operation, a rinsing operation, and a dehydrating operation. The rinsing operation can be performed multiple times, and the dehydration operation can be performed between the washing operation and the rinsing operation, and between the rinsing operation and the next rinsing operation.
在清洗运转开始之前,向滚筒7内投入洗涤剂。控制部60在清洗运转中,在关闭了排水阀13的状态下,打开供水阀12规定时间,从供水路4向洗涤筒3和滚筒7供水,然后通过马达8使滚筒7旋转。由此,滚筒7内的洗涤物L被捶洗。在捶打清洗中,反复进行洗涤物L以某种程度被举起后自然下落至水面的翻滚。通过由翻滚产生的冲击、蓄留于滚筒7的洗涤剂水中含有的洗涤剂成分,从洗涤物L去除污垢。当从翻滚开始经过了规定时间后,控制部60打开排水阀13进行排水时,清洗运转结束。Before the washing operation starts, detergent is poured into the drum 7. During the washing operation, the control unit 60 opens the water supply valve 12 for a predetermined period of time with the drain valve 13 closed to supply water from the water supply path 4 to the washing tub 3 and the drum 7, and then the motor 8 rotates the drum 7. As a result, the laundry L in the drum 7 is beaten. In the beating washing, the washing L is repeatedly lifted up to some extent and then naturally falls to the surface of the water. The impact caused by the tumbling and the detergent components contained in the detergent water stored in the drum 7 remove dirt from the laundry L. When a predetermined time has elapsed from the start of the roll, the control unit 60 opens the drain valve 13 to drain water, and the washing operation ends.
控制部60在漂洗运转中,打开供水阀12规定时间,向洗涤筒3和滚筒7 供水,然后通过马达8使滚筒7旋转。然后,反复进行上述的翻滚,因此洗涤物L被滚筒7内的自来水漂洗。当从翻滚开始经过了规定时间后,控制部60进行排水时,漂洗运转结束。控制部60在脱水运转中,在打开了排水阀13的状态下,使滚筒7脱水旋转。通过由滚筒7的脱水旋转产生的离心力,在滚筒7内的洗涤物L被脱水。通过脱水从洗涤物L渗出的水从排水路5向机外排出。During the rinsing operation, the control unit 60 opens the water supply valve 12 for a predetermined period of time to supply water to the washing tub 3 and the drum 7, and then the motor 8 rotates the drum 7. Then, the tumbling described above is repeated, and therefore the laundry L is rinsed by the tap water in the drum 7. When a predetermined time has elapsed from the start of tumbling and the control unit 60 performs drainage, the rinsing operation ends. The control unit 60 spins the drum 7 while the drain valve 13 is opened during the spin-drying operation. The laundry L in the drum 7 is dehydrated by the centrifugal force generated by the dehydration rotation of the drum 7. The water seeping out from the laundry L by dehydration is discharged from the drain 5 to the outside of the machine.
在脱水运转后,控制部60使送风部21和加热部22工作来分别控制供水阀12、排水阀13、流入阀32、流出阀34以及切换部36的开闭,执行烘干运转。在洗干一体机1中,也可以不经过清洗运转、漂洗运转以及脱水运转,而仅执行烘干运转。After the dehydration operation, the control unit 60 operates the air blowing unit 21 and the heating unit 22 to control the opening and closing of the water supply valve 12, the drain valve 13, the inflow valve 32, the outflow valve 34, and the switching unit 36, respectively, to perform the drying operation. In the integrated washer-dryer 1, it is also possible to perform only the drying operation without going through the washing operation, the rinsing operation, and the dehydrating operation.
还参照作为表示烘干运转的流程图的图3,在烘干运转开始时,控制部60使加热部22工作而将加热部22的散热部22A预热(步骤S1),在关闭了流出阀34的状态下打开流入阀32(步骤S2)。由此,来自龙头的水通过供水路4和流入路31而被供给至滤水器30的容器40内来蓄留。此时,控制部60以使容器40内的水不飞散的方式停止送风部21。即,控制部60为了烘干运转开始而在送风部21工作之前打开流入阀32并向容器40内蓄水。当水位传感器61检测出的容器40内的水位上升至循环路20的第二支路20BE的下端附近的基准水位W,激活滤水器30的功能,因此控制部60关闭流入阀32而结束向滤水器30的供水。3, which is a flowchart showing the drying operation, when the drying operation starts, the control unit 60 activates the heating unit 22 to preheat the heat sink 22A of the heating unit 22 (step S1), and closes the outflow valve In the state of 34, the inflow valve 32 is opened (step S2). Thereby, the water from the faucet is supplied to the container 40 of the water filter 30 through the water supply path 4 and the inflow path 31, and is stored. At this time, the control unit 60 stops the air blowing unit 21 so that the water in the container 40 does not scatter. In other words, the control unit 60 opens the inflow valve 32 and stores water in the container 40 before the air blowing unit 21 operates in order to start the drying operation. When the water level in the container 40 detected by the water level sensor 61 rises to the reference water level W near the lower end of the second branch 20BE of the circulation path 20, the function of the water filter 30 is activated, so the control unit 60 closes the inflow valve 32 and ends the flow The water supply of the water filter 30.
基准水位W被设定为比溢水口35A低的位置,但也可以比第二支路20BE的下端高。需要说明的是,当容器40内的水位上升至溢水口35A时,容器40内的一部分水通过溢水口35A而溢出到容器40外的溢水路35并被溢水路35引导至流出路33,通过流出路33和排水路5向机外排出。The reference water level W is set to a position lower than the overflow 35A, but it may be higher than the lower end of the second branch 20BE. It should be noted that when the water level in the container 40 rises to the overflow port 35A, a part of the water in the container 40 overflows through the overflow port 35A to the overflow passage 35 outside the container 40 and is guided to the outflow passage 33 by the overflow passage 35. The outflow path 33 and the drain path 5 are discharged to the outside of the machine.
在向滤水器30供水后,控制部60继续在使加热部22工作的状态下使送风部21工作(步骤S3)。由此,通过如上那样被加热而成为热风的空气以依次流过洗涤筒3和循环路20的方式进行循环。该空气被散布至滚筒7内的洗涤物L来吸收洗涤物L的水分。由此,洗涤物L被烘干。在洗涤筒3内吸收洗涤物L的水分的空气变为潮湿空气,如图1的粗虚线箭头V1所示,从取出口20D取出至循环路20内,在循环路20内向返回口20E流动。After water is supplied to the water filter 30, the control unit 60 continues to operate the air blowing unit 21 in a state where the heating unit 22 is operated (step S3). Thereby, the air heated to become hot air is circulated so as to flow through the washing tub 3 and the circulation path 20 in order. This air is dispersed to the laundry L in the drum 7 to absorb the moisture of the laundry L. Thus, the laundry L is dried. The air that absorbs the moisture of the laundry L in the washing tub 3 becomes moist air, as shown by the thick dashed arrow V1 in FIG. 1, is taken out from the outlet 20D into the circulation path 20 and flows in the circulation path 20 to the return port 20E.
在送风部21的工作开始时,控制部60通过控制切换部36的开闭,使从取 出口20D向循环路20的第一部20BA内取出的空气向第二支路20BE流动。因此,流过第二支路20BE的空气如图1的粗虚线箭头V2所示下降而流入滤水器30的容器40内。流入至容器40内的空气在蓄留于容器40内的水中通过而下降,在容器40的底壁41的跟前改变方向,如图1的粗虚线箭头V3所示在水中上升。此时,该空气通过与容器40内的水进行热交换而被除湿。而且,该空气所含有的异物被容器40内的水捕获而与水一起蓄留于容器40内。由此,能防止异物到达加热部22而使加热部22的性能降低。此外,利用滤水器30的水,不仅能捕获在烘干运转中产生的异物,还能对潮湿空气进行除湿。When the operation of the air blowing unit 21 is started, the control unit 60 controls the opening and closing of the switching unit 36 so that the air taken out from the outlet 20D into the first portion 20BA of the circulation path 20 flows to the second branch 20BE. Therefore, the air flowing through the second branch 20BE descends as shown by the thick dashed arrow V2 in FIG. 1 and flows into the container 40 of the water filter 30. The air flowing into the container 40 passes through the water stored in the container 40 and descends, changes direction in front of the bottom wall 41 of the container 40, and rises in the water as shown by the thick broken line arrow V3 in FIG. 1. At this time, the air is dehumidified by heat exchange with the water in the container 40. Then, the foreign matter contained in the air is captured by the water in the container 40 and stored in the container 40 together with the water. Thereby, it is possible to prevent foreign matter from reaching the heating unit 22 and degrading the performance of the heating unit 22. In addition, the water in the water filter 30 can not only capture foreign matter generated during the drying operation, but also dehumidify the humid air.
容器40配置于在循环路20的上游部分20G中比加热部22靠取出口20D的位置,因此,滤水器30能从刚来自取出口20D向循环路20取出后的空气中迅速地捕获异物。由此,能减小在循环路20中包含异物的空气蔓延的区域,因此能防止异物附着于循环路20的大部分。而且,容器40与加热部22分离而配置,因此即使在容器40内与随着空气与水的热交换的水温上升而相应地产生热气,该热气也难以到达加热部22。The container 40 is arranged at a position closer to the outlet 20D than the heating part 22 in the upstream portion 20G of the circulation path 20. Therefore, the water filter 30 can quickly capture foreign matter from the air just taken out from the outlet 20D to the circulation path 20 . As a result, it is possible to reduce the area where the air containing foreign matter spreads in the circulation path 20, and therefore it is possible to prevent the foreign matter from adhering to most of the circulation path 20. In addition, the container 40 and the heating unit 22 are separated and arranged. Therefore, even if hot air is generated in the container 40 according to the increase in the temperature of the water accompanying the heat exchange between air and water, the hot air hardly reaches the heating unit 22.
这样去除了水分和异物的空气,越过容器40内的水面进一步上升而到达顶壁45,从容器40内流出至循环路20的后部分20B的第二部20BB,如图1的粗虚线箭头V3所示,朝向返回口20E在第二部20BB内上升。如图1的粗虚线箭头V4所示,在上升至第二部20BB内的空气通过送风部21的旋转叶片23而在循环路20的水平部分20A内流向前侧Y1,此时,通过加热部22的散热部22A而被再加热。被再加热的空气下降至循环路20的前部分20C内并前往返回口20E,从返回口20E向洗涤筒3内和滚筒7内供给,被再利用于烘干滚筒7内的洗涤物L。In this way, the air from which moisture and foreign matter has been removed, rises beyond the water surface in the container 40 to reach the top wall 45, and flows out of the container 40 to the second part 20BB of the rear part 20B of the circulation path 20, as shown by the thick dashed arrow V3 in FIG. 1 As shown, it rises in the second portion 20BB toward the return port 20E. As shown by the thick dashed arrow V4 in FIG. 1, the air rising to the second portion 20BB passes through the rotating blades 23 of the air blowing portion 21 and flows to the front side Y1 in the horizontal portion 20A of the circulation path 20. At this time, it is heated by heating. The heat dissipation portion 22A of the portion 22 is reheated. The reheated air descends into the front portion 20C of the circulation path 20 and goes to the return port 20E, is supplied into the washing tub 3 and the drum 7 from the return port 20E, and is reused in the laundry L in the drying drum 7.
如上所述,以下将在循环路20中从取出口20D取出的空气在蓄留于容器40内的水中通过后流动至返回口20E的风道称为“水经由风道”。另一方面,如后所述,以下将在循环路20中从取出口20D取出的空气如图1的粗虚线箭头V5所示通过第一支路20BD,由此绕过容器40内的水而流动至返回口20E的风道称为“水迂回风道”。需要说明的是,烘干运转开始前的待机状态的循环路20是水迂回风道。As described above, the air path through which the air taken out from the outlet 20D in the circulation path 20 passes through the water stored in the container 40 and then flows to the return port 20E is referred to as a "water via air path" hereinafter. On the other hand, as will be described later, the air taken out from the outlet 20D in the circulation path 20 will pass through the first branch 20BD as shown by the thick dashed arrow V5 in FIG. 1, thereby bypassing the water in the container 40. The air passage that flows to the return port 20E is called a "water bypass air passage". It should be noted that the circulation path 20 in the standby state before the start of the drying operation is a water bypass duct.
在烘干运转中的风道保持为水经由风道的状态且空气始终以通过容器40内 的水的方式进行循环的情况下,容器40内的水成为阻力,由此空气的循环恐怕会逐渐变弱。当空气的循环变弱时,供给至洗涤筒3内的热风的风量降低,因此烘干性能降低。因此,控制部60在步骤S3中使送风部21工作后,为了以使在烘干运转中循环的空气的循环路20内的流动切换为水经由风道和水迂回风道中的哪个合适的风道,执行风道确定处理(步骤S4)和风道调整处理(步骤S5)。When the air duct in the drying operation is maintained in a state where water passes through the air duct and air is always circulated through the water in the container 40, the water in the container 40 becomes resistance, and the circulation of air may gradually weaken. When the circulation of air becomes weak, the air volume of the hot air supplied into the washing tub 3 decreases, and therefore the drying performance decreases. Therefore, after the control unit 60 operates the air blowing unit 21 in step S3, in order to switch the flow of the air circulating in the drying operation in the circulation path 20 to which of the water passing air duct and the water bypassing air duct is appropriate For the air channel, the air channel determination process (step S4) and the air channel adjustment process (step S5) are executed.
参照图4,控制部60在风道确定处理中,首先确认温度传感器62的检测值(步骤S11)。在该检测值小于第一阈值的情况下,在循环的低温的空气所含有的尘埃、线头等异物少至不需要利用滤水器30立即捕获的程度。异物少也包含不存在异物的情况。相反,在检测值为比第一阈值高的第二阈值以上的情况下,在循环的高温的空气中含有的异物多至需要利用滤水器30立即捕获的程度。第一阈值和第二阈值通过实验等预先确定并存储于存储器64。此外,在温度传感器62的检测值是循环的空气的温度本身的情况下,第一阈值的一个例子是35度,第二阈值的一个例子是45度。Referring to FIG. 4, the control unit 60 first confirms the detection value of the temperature sensor 62 in the air path determination process (step S11). When the detection value is less than the first threshold value, foreign matter such as dust and lint contained in the circulating low-temperature air is so small that it does not need to be captured immediately by the water filter 30. A small amount of foreign matter includes a case where there is no foreign matter. Conversely, when the detection value is greater than the second threshold value higher than the first threshold value, the foreign matter contained in the circulating high-temperature air is so large that it needs to be immediately captured by the water filter 30. The first threshold and the second threshold are determined in advance through experiments or the like and are stored in the memory 64. In addition, when the detection value of the temperature sensor 62 is the temperature itself of the circulating air, an example of the first threshold value is 35 degrees, and an example of the second threshold value is 45 degrees.
当烘干运转中的温度传感器62的检测值小于第一阈值(在步骤S12中为“是”),即不需要利用滤水器30从循环中的空气中捕获异物时,控制部60通过控制切换部36,以使循环路20内的空气流过第一支路20BD的方式将循环路20内的空气的流动切换至水迂回风道(步骤S13)。即,控制部60在烘干运转中的温度传感器62的检测值小于第一阈值的情况下,控制循环路20内的空气的流动,使空气以不通过滤水器30的容器40内的水的方式进行循环。When the detection value of the temperature sensor 62 during the drying operation is less than the first threshold (Yes in step S12), that is, when the water filter 30 does not need to capture foreign matter from the circulating air, the control unit 60 controls The switching unit 36 switches the flow of air in the circulation passage 20 to the water bypass duct so that the air in the circulation passage 20 flows through the first branch passage 20BD (step S13). That is, when the detection value of the temperature sensor 62 during the drying operation is less than the first threshold value, the control unit 60 controls the flow of air in the circulation path 20 so that the air does not pass through the water in the container 40 of the water filter 30. Way to loop.
当烘干运转中的温度传感器62的检测值为第二阈值以上(在步骤S12中为“否”且在步骤S14中为“是”),即产生利用滤水器30从循环中的空气中捕获异物的需要时,控制部60通过控制切换部36,以使循环路20内的空气流过第二支路20BE的方式将循环路20内的空气的流动切换为水经由风道(步骤S15)。即,控制部60在烘干运转中的温度传感器62的检测值为第二阈值以上的情况下,控制循环路20内的空气的流动,使空气以通过滤水器30的容器40内的水的方式进行循环,由此从循环的空气中捕获异物。When the detection value of the temperature sensor 62 during the drying operation is greater than or equal to the second threshold value ("No" in step S12 and "Yes" in step S14), it is generated by the water filter 30 from the circulating air When it is necessary to capture foreign matter, the control unit 60 controls the switching unit 36 to switch the flow of air in the circulation passage 20 to the water via the air passage in such a way that the air in the circulation passage 20 flows through the second branch passage 20BE (step S15 ). That is, when the detection value of the temperature sensor 62 during the drying operation is equal to or greater than the second threshold, the control unit 60 controls the flow of air in the circulation path 20 so that the air passes through the water in the container 40 of the water filter 30. Circulate in a way, thereby trapping foreign matter from the circulating air.
如上所述,在通过风道确定处理(步骤S4)确定了循环路20中的最佳的风道后,控制部60执行用于反馈的风道调整处理(步骤S5)。参照图5,在风道调整处理中,控制部60首先确认温度传感器62的检测值(步骤S21)。As described above, after the optimal air path in the circulation path 20 is determined through the air path determination process (step S4), the control unit 60 executes the air path adjustment process for feedback (step S5). Referring to Fig. 5, in the air passage adjustment process, the control unit 60 first confirms the detection value of the temperature sensor 62 (step S21).
当烘干运转中的温度传感器62的检测值小于第一阈值时(在步骤S22中为“否”),不需要利用滤水器30从循环中的空气中捕获异物,因此控制部60通过控制切换部36,将循环路20内的空气的流动切换为水迂回风道(步骤S23)。When the detection value of the temperature sensor 62 during the drying operation is less than the first threshold (No in step S22), there is no need to use the water filter 30 to capture foreign matter from the circulating air, so the control unit 60 controls The switching unit 36 switches the flow of air in the circulation path 20 to a water bypass air path (step S23).
当烘干运转中的温度传感器62的检测值为第二阈值以上时(在步骤S22中为“是”且在步骤S24中为“是”),需要利用滤水器30从循环中的空气中捕获异物,因此控制部60通过控制切换部36,将循环路20内的空气的流动切换为水经由风道(步骤S25)。When the detection value of the temperature sensor 62 during the drying operation is greater than or equal to the second threshold value ("Yes" in step S22 and "Yes" in step S24), it is necessary to use the water filter 30 to remove the circulating air Since the foreign matter is captured, the control unit 60 controls the switching unit 36 to switch the flow of air in the circulation path 20 to the water via air duct (step S25).
如果烘干运转中的温度传感器62的检测值为第一阈值以上但小于第二阈值(在步骤S22中为“是”且在步骤S24中为“否”),则控制部60通过控制切换部36,将循环路20内的空气的流动切换为水迂回风道(步骤S26)。控制部60利用计时器65测定在步骤S26中将循环路20内的空气的流动切换为水迂回风道后的经过时间。在该经过时间达到例如几分钟~几十分钟这样的规定时间的情况下(在步骤S27中为“是”),即在烘干运转中的温度传感器62的检测值为第一阈值以上且小于第二阈值的状态持续规定时间的情况下,恐怕会在循环的空气中产生异物并开始增加。在该情况下,控制部60控制切换部36而将循环路20内的空气的流动切换为水经由风道,由此控制循环路20内的空气的流动,使空气以通过容器40内的水的方式进行循环(步骤S25)。由此,能利用滤水器30将在循环的空气中开始产生的异物立即捕获。该规定时间通过实验等预先确定并存储于存储器64。If the detection value of the temperature sensor 62 during the drying operation is greater than or equal to the first threshold but less than the second threshold ("YES" in step S22 and "NO" in step S24), the control unit 60 controls the switching unit 36. Switch the flow of air in the circulation path 20 to a water bypass duct (step S26). The control unit 60 uses the timer 65 to measure the elapsed time after the air flow in the circulation passage 20 is switched to the water bypass duct in step S26. When the elapsed time reaches a predetermined time such as several minutes to several tens of minutes (YES in step S27), that is, the detection value of the temperature sensor 62 during the drying operation is equal to or greater than the first threshold and less than If the state of the second threshold value continues for a predetermined time, foreign matter may be generated in the circulating air and start to increase. In this case, the control unit 60 controls the switching unit 36 to switch the flow of air in the circulation path 20 to water via the air duct, thereby controlling the flow of air in the circulation path 20 so that the air passes through the water in the container 40. The way to loop (step S25). Thus, the water filter 30 can immediately capture foreign matter that has begun to be generated in the circulating air. The predetermined time is determined in advance through experiments or the like, and is stored in the memory 64.
控制部60也可以执行图6所示的风道调整处理。在该情况下,控制部60也首先确认温度传感器62的检测值(步骤S31)。当烘干运转中的温度传感器62的检测值为第二阈值以上时(在步骤S32中为“是”),则需要利用滤水器30从循环中的空气中捕获异物,因此控制部60通过控制切换部36,将循环路20内的空气的流动切换为水经由风道(步骤S33)。在温度传感器62的检测值小于第二阈值但为第一阈值以上的情况下(在步骤S32中为“否”且在步骤S34中为“否”),控制部60也可以通过将循环路20内的空气的流动切换为水经由风道,从循环的空气中捕获异物(步骤S33)。The control unit 60 may also execute the air path adjustment process shown in FIG. 6. In this case, the control unit 60 first confirms the detection value of the temperature sensor 62 (step S31). When the detection value of the temperature sensor 62 during the drying operation is greater than or equal to the second threshold (YES in step S32), the water filter 30 needs to be used to capture foreign matter from the circulating air, so the control unit 60 passes The switching unit 36 is controlled to switch the flow of air in the circulation path 20 to the water via air path (step S33). In the case where the detection value of the temperature sensor 62 is less than the second threshold value but greater than the first threshold value ("No" in step S32 and "No" in step S34), the control unit 60 may also pass the circulation path 20 The flow of the air inside is switched to water passing through the air duct, and foreign matter is captured from the circulating air (step S33).
当烘干运转中的温度传感器62的检测值从第二阈值以上降低至小于第一阈值时(在步骤S32中为“否”且在步骤S34中为“是”),控制部60用计时器 65测定从检测值变为小于第一阈值时起的经过时间。在该经过时间达到例如几分钟~几十分钟这样的规定时间的情况下(在步骤S35中为“是”),即在温度传感器62的检测值从第二阈值以上变为小于第一阈值的状态持续规定时间的情况下,视为循环的空气中的异物减少至不需要捕获的程度。该规定时间通过实验等预先确定并存储于存储器64。When the detection value of the temperature sensor 62 during the drying operation decreases from the second threshold or more to less than the first threshold ("No" in step S32 and "Yes" in step S34), the control unit 60 uses a timer 65 measures the elapsed time from when the detection value becomes smaller than the first threshold value. When the elapsed time reaches a predetermined time such as a few minutes to several tens of minutes (YES in step S35), that is, the detection value of the temperature sensor 62 has changed from the second threshold or more to less than the first threshold. When the state continues for a predetermined period of time, the foreign matter in the circulating air is reduced to the point where it does not need to be captured. The predetermined time is determined in advance through experiments or the like, and is stored in the memory 64.
在温度传感器62的检测值为小于第一阈值的状态的经过时间到达规定时间的情况下(在步骤S35中为“是”),控制部60控制切换部36而将循环路20内的空气的流动切换为水迂回风道,由此控制循环路20内的空气的流动,使空气以不通过容器40内的水的方式进行循环(步骤S36)。由此,在该状态的烘干运转中,能使烘干用的空气顺畅地循环,因此能抑制烘干性能的降低。另一方面,例如当因用户在中途打开门10等而异物流入洗涤筒3内时,温度传感器62的检测值从第二阈值以上变为小于第一阈值的状态不会持续规定时间(在步骤S35中为“否”),因此控制部60通过使循环路20内的空气的流动保持为水经由风道的状态,从循环的空气中捕获异物(步骤S33)。When the detected value of the temperature sensor 62 is less than the first threshold and the elapsed time reaches the predetermined time (YES in step S35), the control unit 60 controls the switching unit 36 to reduce the amount of air in the circulation path 20 The flow is switched to the water bypass duct, thereby controlling the flow of air in the circulation path 20 so that the air is circulated without passing through the water in the container 40 (step S36). Thereby, in the drying operation in this state, the air for drying can be circulated smoothly, and therefore, the reduction in drying performance can be suppressed. On the other hand, when a foreign material flows into the washing tub 3 due to the user opening the door 10 in the middle, the detection value of the temperature sensor 62 changes from the second threshold or more to less than the first threshold for a predetermined time (in step "No" in S35), therefore, the control unit 60 keeps the air flow in the circulation path 20 in a state where water passes through the air duct to capture foreign matter from the circulating air (step S33).
如上所述,控制部60在烘干运转中,通过控制切换部36,仅在需要从循环的空气中捕获异物时,使空气在滤水器30的容器40内的水中通过,在不需要捕获异物时,使空气不通过容器40内的水。在该情况下,与使循环的空气始终通过容器40内的水的情况相比,能在整个烘干运转中使烘干用的空气顺畅地循环,因此能通过充分确保热风的风量,抑制烘干性能的降低。不过,在烘干运转开始时,无论温度传感器62的检测值如何,如图3所示,控制部60必定将循环路20设为水经由风道(步骤S2和步骤S3),因此能利用滤水器30将从烘干运转前存在并附着于滚筒7等的异物捕获。As described above, during the drying operation, the control unit 60 controls the switching unit 36 to allow the air to pass through the water in the container 40 of the water filter 30 only when foreign matter needs to be captured from the circulating air. In the case of foreign matter, the air does not pass through the water in the container 40. In this case, compared to the case where the circulating air always passes through the water in the container 40, the drying air can be circulated smoothly throughout the drying operation. Therefore, the air volume of the hot air can be sufficiently ensured to suppress drying. Decrease in dry performance. However, at the beginning of the drying operation, regardless of the detection value of the temperature sensor 62, as shown in FIG. 3, the control unit 60 must set the circulation path 20 as a water passage air path (step S2 and step S3), so the filter can be used. The water tank 30 captures foreign matters that existed before the drying operation and adhered to the drum 7 and the like.
当控制部60如此将步骤S5的风道调整处理持续例如1~3小时左右的规定时间时,停止加热部22(步骤S6)。在该状态下,送风部21继续工作,因此冷风循环而向滚筒7内的洗涤物L散布,由此洗涤物L被冷却。然后,当控制部60将冷风的循环持续几十分钟左右的规定时间时,作为烘干运转结束时的处理,通过停止送风部21并打开流出阀34来执行滤水器30的排水(步骤S7)。由此,滤水器30的容器40内的水和异物被排出至流出路33,并从流出路33被引导至排水路5。即,如果将容器40内的水倒掉,则蓄留于容器40内的异物也随着水 被排出。When the control unit 60 continues the air passage adjustment process of step S5 for a predetermined time, for example, about 1 to 3 hours, the heating unit 22 is stopped (step S6). In this state, since the blower 21 continues to operate, the cold air circulates and spreads to the laundry L in the drum 7, whereby the laundry L is cooled. Then, when the control unit 60 continues the circulation of the cold air for a predetermined time of about several tens of minutes, as a process at the end of the drying operation, the air blowing unit 21 is stopped and the outflow valve 34 is opened to perform drainage of the water filter 30 (step S7). Thereby, the water and foreign substances in the container 40 of the water filter 30 are discharged to the outflow path 33 and guided from the outflow path 33 to the drain path 5. That is, if the water in the container 40 is poured, the foreign matter stored in the container 40 is also discharged with the water.
被引导至排水路5的异物被排水过滤器6(参照图1)捕获。若用户去除蓄留于排水过滤器6的异物,则也会去除容器40内的异物,因此也可以不进行利用滤水器30而去除容器40内的异物的维护。由此,滤水器30的维护变得容易,因此能谋求关于烘干运转的使用方便性的提高。需要说明的是,也可以省略排水过滤器6,在该情况下,被引导至排水路5的异物通过排水路5而直接向机外排出。The foreign matter guided to the drain passage 5 is captured by the drain filter 6 (refer to FIG. 1). If the user removes the foreign matter stored in the drain filter 6, the foreign matter in the container 40 is also removed. Therefore, the maintenance of removing the foreign matter in the container 40 using the water filter 30 may not be performed. As a result, the maintenance of the water filter 30 becomes easy, and therefore, the usability of the drying operation can be improved. It should be noted that the drain filter 6 may be omitted. In this case, the foreign matter guided to the drain path 5 passes through the drain path 5 and is directly discharged to the outside of the machine.
当容器40内没有水时,烘干运转结束。控制部60可以根据水位传感器61的检测结果来判断容器40内是否有水,也可以通过经过所需时间来判断。该所需时间通过实验等预先确定,并存储于存储器64。如此,容器40内排空,因此能防止在从烘干运转结束后到下一次的烘干运转开始为止的期间水残留于容器40内而在容器40内繁殖霉菌、杂菌的情况。When there is no water in the container 40, the drying operation ends. The control unit 60 may determine whether there is water in the container 40 based on the detection result of the water level sensor 61, or may determine whether the required time has elapsed. The required time is determined in advance through experiments or the like, and is stored in the memory 64. In this way, the container 40 is emptied, and therefore, it is possible to prevent water from remaining in the container 40 during the period from the end of the drying operation to the start of the next drying operation, and the growth of molds and other bacteria in the container 40 can be prevented.
本发明并不限定于以上说明的实施方式,能在技术方案所记载的范围内进行各种变更。The present invention is not limited to the embodiments described above, and various modifications can be made within the scope described in the technical solution.
例如,在上述的实施方式中,循环路20在后部分20B的中途部20BC中分支为第一支路20BD和第二支路20BE,由此能切换为上述的水迂回风道和水经由风道(参照图1)。取而代之,如图7所示的变形例,中途部20BC也可以不分支而从第一部20BA的后端弯折而向下侧Z2延伸,贯通顶壁43并配置于内部空间40A。需要说明的是,在图7中,对与上述构件的功能相同的构件标注相同的附图标记。在变形例中的中途部20BC的下端部通过在内部空间40A开口而与容器40相连。因此,如粗虚线箭头所示,为了循环而从取出口20D被引入循环路20内的空气必定经由滤水器30的容器40内而前往返回口20E。For example, in the above-mentioned embodiment, the circulation path 20 is branched into the first branch 20BD and the second branch 20BE at the midway portion 20BC of the rear part 20B, thereby switching to the above-mentioned water bypass air channel and water passing wind channel. Road (refer to Figure 1). Instead, as shown in the modification shown in FIG. 7, the midway portion 20BC may be bent from the rear end of the first portion 20BA without branching to extend to the lower side Z2, penetrate the top wall 43 and be arranged in the internal space 40A. It should be noted that, in FIG. 7, members having the same functions as the above-mentioned members are given the same reference numerals. The lower end of the halfway portion 20BC in the modified example is connected to the container 40 by opening in the internal space 40A. Therefore, as indicated by the thick dashed arrow, the air introduced into the circulation path 20 from the outlet 20D for circulation must go to the return port 20E through the container 40 of the water filter 30.
在变形例的情况下,水在容器40内蓄留至基准水位W时的循环路20是上述的水经由风道,容器40排空时的循环路20是上述的水迂回风道。控制部60通过控制流入阀32和流出阀34中的至少任一方的开闭,向容器40内蓄水并将循环路20切换为水经由风道,或排空容器40而将循环路20切换为水迂回风道。作为一个例子,控制部60在关闭了流出阀34的状态下打开流入阀32,使水从流入路31流入容器40内,由此能在容器40内蓄水,通过将流出阀34打开而使容器40内的水从流出路33流出,能排空容器40。In the case of the modified example, the circulation path 20 when the water is stored in the container 40 to the reference water level W is the above-mentioned water via duct, and the circulation path 20 when the container 40 is emptied is the above-mentioned water bypass duct. The control unit 60 controls the opening and closing of at least one of the inflow valve 32 and the outflow valve 34 to store water in the container 40 and switch the circulation path 20 to a water via air duct, or to empty the container 40 to switch the circulation path 20 It is a circuitous wind channel for water. As an example, the control unit 60 opens the inflow valve 32 with the outflow valve 34 closed to allow water to flow into the container 40 from the inflow path 31, thereby storing water in the container 40, and opening the outflow valve 34 to make The water in the container 40 flows out from the outflow path 33, and the container 40 can be emptied.
然后,在变形例的风道确定处理(步骤S4)中,当烘干运转中的温度传感器62的检测值小于第一阈值时(图4的步骤S12中为“是”),控制部60也将循环路20切换为水迂回风道(步骤S13),因此循环的空气在空的容器40内不通过水而流动。此外,当烘干运转中的温度传感器62的检测值为第二阈值以上时(在步骤S12中为“否”且在步骤S14中为“是”),控制部60将循环路20切换为水经由风道(步骤S15),因此空气以通过蓄留于容器40内的水的方式进行循环。此外,在变形例的风道调整处理(步骤S5)中,如上所述,控制部60也根据循环的空气中的异物的量,将循环路20切换为水迂回风道和水经由风道(参照图5和图6)。Then, in the air path determination process (step S4) of the modified example, when the detection value of the temperature sensor 62 during the drying operation is less than the first threshold value ("Yes" in step S12 of FIG. 4), the control unit 60 also Since the circulation path 20 is switched to the water bypass duct (step S13), the circulating air flows in the empty container 40 without passing through water. In addition, when the detection value of the temperature sensor 62 during the drying operation is equal to or greater than the second threshold value ("No" in step S12 and "Yes" in step S14), the control unit 60 switches the circulation path 20 to water Since the air passes through the air duct (step S15), the air circulates so as to pass through the water stored in the container 40. In addition, in the air passage adjustment process (step S5) of the modified example, as described above, the control unit 60 also switches the circulation passage 20 to the water bypass air passage and the water passage air passage ( Refer to Figure 5 and Figure 6).
在变形例中,通过由这样的控制部60实现的流入阀32、流出阀34的控制,在烘干运转中,仅在需要从循环的空气中捕获异物时在容器40内蓄水并使空气在容器40内的水中通过,在不需要捕获异物时排空容器40使空气在容器40内不受水的阻力而顺畅地流动。In the modified example, by controlling the inflow valve 32 and the outflow valve 34 by such a control unit 60, in the drying operation, only when foreign matter needs to be captured from the circulating air, water is stored in the container 40 and the air is released. The water in the container 40 passes through, and the container 40 is emptied when there is no need to capture foreign objects so that the air flows in the container 40 smoothly without the resistance of the water.
上述的各种特征可以适当组合。例如,控制部60可以仅执行图5所示的风道调整处理和图6所示的风道调整处理中的任一方,也可以将该处理以两个阶段执行。此外,控制部60也可以将切换部36的控制(参照图1)与上述的变形例中的流入阀32、流出阀34的控制(参照图7)组合,将循环路20切换为水迂回风道和水经由风道。The various features mentioned above can be combined as appropriate. For example, the control unit 60 may execute only one of the air passage adjustment processing shown in FIG. 5 and the air passage adjustment processing shown in FIG. 6, or may execute the processing in two stages. In addition, the control unit 60 may combine the control of the switching unit 36 (refer to FIG. 1) with the control of the inflow valve 32 and the outflow valve 34 (refer to FIG. 7) in the above-mentioned modification to switch the circulation path 20 to the water bypass air. The road and water pass through the wind channel.
在上述的实施方式中的滚筒式的洗干一体机1中,也可以以轴线J相对于水平方向H倾斜的方式配置滚筒7。此外,洗干一体机1也可以是轴线J沿纵向延伸的立式洗干一体机。In the drum-type integrated washer-dryer 1 in the above-described embodiment, the drum 7 may be arranged such that the axis J is inclined with respect to the horizontal direction H. In addition, the integrated washer-dryer 1 may also be a vertical integrated washer-dryer with the axis J extending in the longitudinal direction.
