作为改进的对策,本发明人考虑过将上述滚筒的旋转轴和电动机的转子直接连接的形态、即用电动机直接对滚筒进行驱动的结构。 As an improvement countermeasure, the present invention is considered to form the rotor rotation axis of the drum and a motor directly connected, i.e., a structure for directly driving the drum motor. 在这种场合,可以削减零件数量和减轻振动·噪音,而且可将电动机的旋转直接传递给滚筒,故增大了滚筒旋转控制的灵活性。 In this case, the number of parts can be reduced and reduce vibration and noise, but also the rotation of the motor is directly transmitted to the drum, it increases the flexibility of the drum rotation control. 另一方面,过去的滚筒式洗衣机会出现衣物紧贴在滚筒内面或相互缠绕的现象,这一方面也有待于改进。 On the other hand, past the laundry drum type washing machine will be close to the surface of the drum or twist phenomenon is also room for improvement in this regard.

鉴于上述情况,本发明的目的在于提供一种滚筒式洗衣机,采用电动机直接驱动滚筒的结构,同时能有效地防止衣物紧贴或缠绕等。 In view of the above circumstances, an object of the present invention is to provide a drum type washing machine using the motor to directly drive the drum structure, while the laundry is effectively prevented against the wound or the like.

本发明的技术方案1包括:支承在外箱内的水槽、设在该水槽内可围绕大致水平的轴旋转且容纳衣物的滚筒、直接对该滚筒进行旋转驱动的电动机、控制前述电动机以使前述滚筒在90度以下的旋转角度内进行多次正反转的小角度旋转动作控制装置。 Aspect of the present invention comprises: a support inside the outer tank, disposed in the water tank is rotatable about a substantially horizontal axis and the drum receiving the laundry, the drum is directly rotationally driving the motor, controls the motor so that the drum multiple reversing the rotation angle of the small angle of 90 degrees or less rotation of the operation control means.

在上述结构中,由于使滚筒在90度以下的旋转角度内、即“1/4”旋转范围内进行多次正反旋转,故滚筒在较短周期内形成往返旋转,能够将紧贴在滚筒内面的衣物剥下,或是将在滚筒内的上部结成一团的衣物松解开,还可消除脱水时的不平衡,便于取出干燥后的衣物。 In the above structure, since the rotation angle of the drum 90 degrees or less, i.e., "1/4" multiple forward and reverse rotation within the rotation range, so that reciprocal rotary drum is formed, it can be close to the drum in a relatively short period the laundry peeled off the inner surface, or the upper part of the laundry drum into a ball loose knot untied, can eliminate imbalance during dewatering, the laundry taken out to facilitate drying. 在这种场合,由于是用电动机直接对滚筒进行驱动,故可避免从电动机到滚筒的旋转传动损耗,能使滚筒可靠运转。 In this case, since the roller is directly driven by the motor, it is possible to avoid rotation of the drum from the motor to transmission losses, the drum can operate reliably.

通过使滚筒以30度以下的旋转角度多次正反旋转,可以使滚筒以更短的周期往返旋转,能更可靠地将衣物剥下和松解开。 By rotating the drum at an angle of 30 degrees or less times forward and backward rotation, the drum may be a shorter period reciprocatively rotated, the laundry can be more reliably peeled loose and unlock. 另外通过,将滚筒的旋转角度设定在10度以上,可避免滚筒产生振动。 By Further, the rotation angle of the drum is set to 10 degrees or more, can avoid the vibration of the drum.

技术方案3的特点是,小角度旋转动作控制装置在运转开始时实施控制。 Characteristics of aspect 3, the small angle rotating operation control means controls the start of the operation embodiment.

在洗涤工序之前将衣物松解开,对于提高洗涤效果极为有利。 In the washing step prior to the unlock loose clothing, extremely advantageous to enhance washing effect. 而在上述结构中,小角度旋转动作控制装置是在运转开始时即实施控制,故必然是在洗涤工序之前将衣物松解开,故洗涤效果更佳。 In the above structure, the small angle rotating operation control means is at the start of the operation control embodiment i.e., it must be washed prior to step unlock the loose clothing, and therefore a better washing effect.

技术方案4的特点是,小角度旋转动作控制装置在脱水工序之后实施控制。 4 is a characteristic aspect, a small angular rotation operation control means controls embodiment after the dehydration step.

在脱水工序中滚筒高速旋转,故在脱水工序结束的状态下,衣物往往紧贴在滚筒内面。 The drum rotates at high speed in the dehydration step, the dehydration step so that at the end of a state, the laundry often close to the drum surface. 而在上述结构中,小角度旋转动作控制装置是在脱水工序之后实施控制,故即使衣物紧贴在滚筒内面也能有效地将其剥离,在实施脱水工序后的漂洗工序时,可提高该漂洗工序中的漂洗效果。 In the above structure, the small angle rotating operation control means is control over after the removing step, so that even if the laundry against the drum surface can be efficiently stripped off in the rinsing step after the dehydration step, can improve the rinsing the effect of the rinsing step.

技术方案5的特点是,小角度旋转动作控制装置在干燥工序中或干燥工序结束后实施控制。 Aspect 5 is characterized by a small angular rotation operation control means in the drying step or the drying step after controlling embodiments.

在干燥工序中衣物会在滚筒内结成一团。 It will bear ball laundry within the drum in a drying step. 或是在干燥工序结束时,衣物在滚筒深处结成一团而不便取出。 Or at the end of the drying step, the laundry ball and inconvenient junction depths of the drum removed. 而在上述结构中,小角度旋转动作控制装置在干燥工序中或干燥工序结束时实施控制,故能够在干燥过程中松解衣物,或便于在干燥运转结束后取出衣物。 In the above structure, the small angle rotating operation control means control embodiment or at the end of the drying step in the drying process, it is possible to loosen the laundry in the drying process, or facilitate removal of the laundry after the drying operation.

技术方案6的特点是具有检测滚筒旋转不匀的旋转不匀检测装置,小角度旋转动作控制装置在该旋转不匀检测装置检测到旋转不匀时实施控制。 6 is a characteristic aspect unevenness having rotational nonuniformity detecting means for detecting rotation of the drum, small angle rotating operation control means control embodiment detects the rotational irregularity of rotational nonuniformity detecting means.

如果能检测到衣物紧紧贴在滚筒上的状态或衣物结成一团的状态,则能及时地实施小角度旋转动作控制。 If the laundry can be detected in a state tightly affixed on the drum or the laundry drew together state, the embodiment can promptly small angle rotating operation control. 在这种场合,最重要的是检测到衣物的紧贴状态或结成一团的状态,而本发明人则认为,检测到滚筒的旋转不匀,即可检测到贴附·结团的状态。 In this case, the most important is to detect the close contact state or in a state the laundry junction ball, but the present invention is that, the rotation of the drum detected irregularity can detect stuck-agglomerated state . 而在上述结构中,小角度旋转动作控制装置是在旋转不匀检测装置检测到旋转不匀时实施控制,故在发生紧贴·结团时能及时消除,不仅能迅速解除紧贴·结团现象,还可避免无谓的控制。 In the above structure, the small angle rotating operation control means in the rotational nonuniformity detecting means detects the rotation control uneven embodiment, when it can promptly eliminate close-clumping occurs, not only can rapidly released close-clumping phenomenon, but also to avoid unnecessary control.

技术方案7的特点是,进水工序和小角度旋转动作控制装置的控制实施同时进行。 7 is a characteristic aspect, water and a small angular rotation step operation control means control embodiment simultaneously.

通过小角度旋转动作控制装置的控制实施,可将紧贴在滚筒内面的衣物剥离或是将在滚筒内的上部结团的衣物松解,但如果是在进水工序中实施该控制,则进入的水有助于剥离衣物且可赋与衣物柔软性,由于这些作用相互配合,使消除紧贴·结团的效果更佳。 Operation control means controls the rotation of the embodiments through a small angle can be close to the surface of the laundry peeled off drum agglomeration or upper portion of the laundry within the drum debonding, but if it is implemented in the control step, the water, the process proceeds the water helps release the laundry and the laundry can be endowed with flexibility by virtue of these cooperate with each other, so that a better effect against · eliminate agglomerated.

技术方案8的特点是,具有在规定水位及规定时间实施小角度旋转动作控制的洗涤过程。 8 is a characteristic aspect having a predetermined level in a predetermined time and the washing process embodiment a small angle of rotation of the operation control.

该技术方案8的发明着眼于以下一点。 This aspect of the invention focuses on the following point 8. 即,使滚筒在90度以下的旋转角度内多次正反旋转,如果水槽内有一定量的水,则可对衣物进行弱洗。 That is, reverse rotation of the drum a plurality of times in the rotating angle of 90 degrees or less, if a certain amount of water in the tank can be a weak wash the laundry. 于是,由于具有在规定水位及规定时间实施小角度旋转动作控制的洗涤过程,故通过实行这一过程,可以轻柔地洗涤衣物。 Thus, since the water level at a predetermined time and the predetermined small angle rotating washing process embodiment motion control, so that through the implementation of this process, the laundry can be washed gently.

技术方案9的特点是,具有由使用者操作的手动输入装置,小角度旋转动作控制装置根据该手动输入装置的操作而实施控制。 9 is a characteristic aspect, a manual input means operated by the user, small angle rotating operation of the operation control apparatus according to the embodiment of the manual input control means.

使用者在譬如干燥工序结束后取出衣物时,衣物的结团有时还未松解。 After the user such as the drying step when removing the laundry, the laundry may not yet release clumping. 或是在暂停运转取出衣物时也会出现同样情况。 Or when suspended running out clothes the same situation will arise. 而在上述结构中,使用者在这种场合只要操纵手动输入装置,即可进行所需的小角度旋转动作。 In the above configuration, the user manually manipulated in this case as long as the input device, to make the desired small angle rotating operation.

技术方案10的特点是,小角度旋转动作控制装置的实行时间为5秒以内。 10 is a characteristic aspect of the implementation of the small angle rotating operation of the time control device within 5 seconds.

如上所述,小角度旋转动作是使滚筒进行短周期的正反旋转,故会在电动机及其电气和机械驱动部分产生正向及反向的巨大起动负荷。 As described above, the operation is small angular rotation of the drum for a short period of forward and reverse rotation, it will have a huge forward and reverse start-up load of the motor and the electrical and mechanical driving portion. 而在上述结构中,小角度旋转动作控制装置的实行时间是在5秒以内,故可减少电动机及其电气和机械驱动部分的负担。 In the above structure, the implementation time of the rotational operation control means small angle is within five seconds, it can reduce the burden of a drive motor and its electrical and mechanical parts.

技术方案11的特点是,具有加热器,小角度旋转动作控制装置在该加热器通电时不实施控制。 11 is a characteristic aspect, a heater, a small angular rotation control operation of the control device is not performed at the time of energization of the heater.

由于小角度旋转动作是使滚筒在短周期进行正反旋转,故会对电动机施加正向及反向的起动负荷,电动机电流也会增大。 Due to the small angular rotation movement is forward and reverse rotation of the drum in a short period, it would be applied to the motor in forward and reverse start-up load, the motor current increases. 在这种状况下,一旦在干燥工序中使用的加热器通电,就可能超过家用的额定电流而切断电源断路器。 In this situation, by using the heater is energized in the drying process, may exceed the rated current home cut off the power circuit breaker. 而在上述结构中,由于在加热器通电时不实施对小角度旋转动作的控制,故不会有过大的电流流过。 In the above structure, since no control over the operation of the small angle rotating when the heater is energized, it will not have an excessively large current flows.

此时实行的小角度旋转动作控制工序是在脱水工序之后进行,故譬如在脱水引起衣物紧贴在滚筒10的内面时,通过上述小角度旋转动作即可将衣物剥离。 At this time, a small angular rotation imposed operation control step is performed after the dehydration step, it causes such as dehydrating the laundry against the drum 10 at an inner surface of the rotary motion to the laundry is peeled off by the above-described small angle. 另外,在这种场合,同时实施进水工序,故通过注入的水可以将衣物剥离并使衣物柔软,由于这些作用,使消除紧贴的效果更佳。 Further, in this case, step water simultaneously, it is possible to peel off the laundry and the laundry by injecting soft water, by virtue of these, so that better effect against elimination.

(6)轻柔洗运转中的各工序(6-1)停止工序(6-2)轻柔洗运转工序···使洗衣机电动机17反复地正向旋转12秒(55rpm)、停止3秒、反向旋转12秒(55rpm)。 (6) gently washed each step (6-1) during operation stopping step (6-2) ????? gentle wash operation step 17 so that the washing machine motor 12 seconds repeatedly forward rotation (55 rpm), stopped for 3 seconds, reverse 12 seconds of rotation (55rpm).

另外,在通过操作轻柔洗过程选择开关而选择了轻柔洗过程后,一旦操纵起动开关,控制电路44即如图7的动作时间图所示,对各机器进行控制。 Further, after gentle washing procedure selection switch gentle washing process is selected by operating the starter switch upon manipulation, the operation control circuit 44 shown in FIG. 7, i.e. FIG time, controlling each machine. 在该图7中,表示了通常用的进水阀21和排水阀电动机23的动作,而省略了其他机器的动作。 In FIG. 7, showing the operation of the inlet valve 21 is typically used and the drain valve motor 23, the operation of the other machines are omitted.

在该轻柔洗过程中,实行洗涤运转(进水工序、洗涤工序)、实行2次的漂洗运转(脱水工序、制动工序、进水工序、第1漂洗工序、第2漂洗工序)及最后脱水运转(最后脱水工序、制动工序),其特点如下。 In this gentle washing process, the implementation of the washing operation (step water washing step), the implementation of the operation rinsed twice (dehydration step, the braking step, the water step, a first rinsing step and second rinsing step) and finally dehydration operation (the last dewatering step, the step of braking), the following features.

在洗涤工序中,当水达到规定的水位时,在洗涤所需的27分钟内,以30秒钟的停止间隔进行多次5秒钟的小角度旋转动作控制。 In the washing step, when the water reaches a predetermined level, at 27 minutes of washing required to stop a plurality of times at intervals of 30 seconds to 5 seconds, it will be a small angular rotation operation control. 1次小角度旋转动作控制与前述的场合相同,是使洗衣机电动机17正向旋转30度机械角度(旋转速度为50rpm),经过极短的时间后反向旋转30度,这样作为1个周期,在5秒钟内反复进行5个周期。 1 where the same small angle rotational operation of the control, so that the washing machine motor 17 is forward rotated 30 degrees mechanical angle (rotation speed of 50 rpm), a very short time after the reverse rotation of 30 degrees, such as one cycle, 5 cycles is repeated within 5 seconds. 由此使滚筒10正反旋转5个周期。 Whereby the forward and reverse rotation of the drum 10 5 cycles. 另外,在第1漂洗工序和第2漂洗工序中,在规定的所需时间内,同样进行小角度旋转动作控制。 Further, in the first rinsing step and second rinsing step, a predetermined desired period of time, the same control operation for a small angular rotation.

在该轻柔洗过程中,是在规定的水位及规定时间实行小角度旋转动作控制,通过滚筒10短周期的正反旋转,可以对衣物进行弱洗,可得到对衣物进行轻柔洗的效果。 In this gentle washing process, the water level is implemented at a predetermined time and a predetermined small angle rotational operation control, forward and reverse rotation of the drum 10 short cycle, may be weak wash the laundry, the laundry can be obtained gentle washing effect.

采用上述的本实施例,是按照使滚筒10以30度的旋转角度进行多次正反旋转的方式来控制电动机17,故可使滚筒10在短周期内往返旋转,可以有效地将紧贴于滚筒10内面的衣物剥离,同时能有效地将在滚筒10内结成一团的衣物松解。 With the above embodiment according to the present embodiment, the drum 10 is performed a plurality of times in accordance with forward and reverse rotation of the rotation angle of 30 degrees in a manner to control the motor 17, so that the roller 10 can rotate round a short period, it can be efficiently close contact laundry peeled off the inner surface of the drum 10, while effective to release the laundry in the drum 10 of the junction ball. 还能消除脱水时的不平衡,便于干燥后取出衣物。 But also to eliminate unbalance dehydration, facilitates removal of the laundry after drying. 在这种场合,由于是用电动机17直接对滚筒10进行旋转驱动,故不会产生从电动机17到滚筒10的旋转传动损耗,能使滚筒可靠地运转,提高了可靠性。 In this case, since the drum 10 is rotationally driven directly by the motor 17 is not generated from the rotation transmission loss of the motor 17 to the drum 10, the drum can operate reliably, improving the reliability.

尤其是,通过将滚筒10的旋转角度定在10度以上,可避免滚筒10产生振动。 In particular, by the rotation angle of the drum 10 is set at 10 degrees or more, can avoid the vibration of the drum 10. 即,如果将滚筒10的旋转角度定在小于10度,使滚筒10以极短的周期正反旋转,就可能发生滚筒10的振动,而本实施例无此种缺陷。 That is, if the rotation angle of the drum 10 is set at less than 10 degrees, the drum 10 in an extremely short period of forward and reverse rotation, on the vibration of the drum 10 may occur, whereas no such defect according to the present embodiment.

另外,滚筒10在90度以下的旋转角度内进行多次正反旋转,可达到初期的目的。 Further, a plurality of times forward and reverse rotation roller 10 in the rotating angle of 90 degrees or less, the initial purpose can be achieved.

采用本实施例,由于是在脱水工序之后实行小角度旋转动作控制,故即使衣物在脱水工序中紧贴在滚筒10内面,也能有效地将它们剥离,在脱水之后实行漂洗工序时,可提高该漂洗工序的漂洗效果。 According to the present embodiment, since the implementation of a small angle after the removing step rotational operation control, so that even if the laundry in the dehydration step against 10 the inner surface of the drum, can be efficiently they release, when the implementation of the rinsing step after dewatering, can be improved the rinsing step of rinsing effect.

采用本实施例,由于是在干燥工序结束后实行小角度旋转动作控制,故当干燥工序结束、衣物在滚筒10的深处结成一团而不便取出时,可以将该衣物松解开,便于衣物取出。 According to the present embodiment, since the implementation of a small angle of rotation at the end of the drying operation control step, so when the end of the drying process, the laundry taken out and inconvenient ball deep junction drum 10, it is possible to unlock the loose clothing, to facilitate remove the laundry. 另外,也可在干燥工序中实行上述小角度旋转动作控制。 Further, the rotation operation of the above-described control can be implemented in a small angle in the drying step. 这样,如果在干燥工序中衣物在滚筒内结团,也可在干燥工序中将衣物松解开,有助于提高干燥效率。 Thus, if the laundry in the drum agglomeration, can be solved in the loose laundry drying step in the drying process, it helps to improve drying efficiency.

采用本实施例,由于是同时实行进水工序和小角度旋转动作控制,故可利用注入的水来剥离衣物并使衣物更加柔软,由于这些作用,使消除紧贴和结团现象的效果更佳。 Better results using the embodiment of the present embodiment, since the simultaneous implementation of water and a small angular rotation step operation control, it can be injected using the laundry and the laundry release water softer, due to these effects, and so close to eliminate the phenomenon of agglomeration .

另外,由于洗涤过程具有在规定水位及规定时间实行小角度旋转动作控制的过程,故可以对衣物进行弱洗,具有对衣物进行轻柔的洗涤效果。 Further, since the washing procedure with water at a predetermined time and the predetermined angle of rotation of the small implement control operation, it is possible for weak wash laundry, the laundry has a gentle washing effect.

再有,由于设置了由使用者操作的手动输入装置、即小角度旋转动作指定开关,且在操纵该开关时实行小角度旋转动作控制,故可由使用者根据需要进行小角度旋转动作,可根据使用者的需要将衣物松解开,十分方便。 Further, since the manual input device operated by the user, i.e., small angle rotating operation designating switch, and the implementation of small-angle rotational operation of the control switch is manipulated, so that the user may be required small angle rotating operation, according to the user will need to unravel loose clothing, very convenient.

尤其是本实施例将小角度旋转动作控制的实行时间定为5秒以内,故可减少电动机17及其作为电气驱动部分的开关元件40a~40f和作为机械驱动部分的旋转轴14及轴承16的负担,延长使用寿命。 This particular embodiment of the small angle rotating operation of the control implementation is scheduled for within five seconds, it can reduce the electric drive motor 17 and a switching element portion 40a ~ 40f and the rotary shaft as a mechanical driving portion 14 and the bearing 16 burden and prolong life.

另外,采用本实施例,在干燥加热器34通电时不实行小角度旋转动作控制,故可避免过大电流流过。 Further, with the present embodiment, the practice of controlling the small angular rotation during operation of the drying heater 34 is energized, it can avoid excessive current flows. 即,上述的小角度旋转动作会使电动机电流增大,如果在此状态下使干燥加热器34通电,则可能超过家庭的额定电流值,使电源断路器切断。 That is, the above-described operation causes a small angle rotation of the motor current increases, when the drying heater 34 is energized in this state, it may exceed the rated current family, the power source circuit breaker to open. 而上述结构就没有这样的缺陷。 And said structure has no such drawbacks.

还有,采用上述实施例时,小角度旋转动作控制也可在运转开始时、即洗涤工序之前实行。 Further, when the above-described embodiment, a small angle of rotation can also control the operation start of the operation, i.e., before the implementation of the washing step. 这样,就可在洗涤工序之前通过小角度旋转动作控制将衣物松解开,有助于提高洗涤效果。 Thus, the rotation can be operated by a small angle before the washing step of the laundry loose unlock control, help to improve the washing effect.

采用本实施例,通过检测滚筒10的旋转不匀,可以检测到衣物的紧贴·结团现象,而且由于是在检测到旋转不匀之后实行小角度旋转动作控制,故可以在发生紧贴·结团现象时及时消除,不仅能迅速消除紧贴·结团现象,还可避免无谓的控制。 According to the present embodiment, by detecting the rotation unevenness of the cylinder 10 can be detected close to the laundry-agglomeration phenomenon, and because a small angle of rotation is the implementation of control operation after detecting the rotational irregularity, it may take place against · when the timely elimination of agglomeration phenomenon, not only can quickly eliminate the phenomenon of close-knot group, but also to avoid unnecessary control.
