In this application.
技术领域Technical field
本发明涉及洗衣机领域,具体涉及一种洗衣机驱动系统,本发明还涉及了该驱动系统应用的洗衣机,尤其适合应用于广大家庭使用的中低档的洗衣机领域。The invention relates to the field of washing machines, in particular to a washing machine driving system, and to a washing machine applied to the driving system, and is particularly suitable for the field of middle and low-end washing machines used by the majority of households.
背景技术Background technique
洗衣机的主要工作是由驱动机构驱动波轮转动,搅动水流和衣物转动,达到洗涤衣物的目的。目前常用驱动机构的动力源为电机,由电机的输出轴将电机旋转时的力矩传递给减速装置,再将减速装置的输出轴与波轮相连,从而带动波轮转动。The main job of the washing machine is to drive the pulsator to rotate, stir the water flow and the clothes to rotate, to achieve the purpose of washing the clothes. At present, the power source of the common driving mechanism is a motor, and the output shaft of the motor transmits the torque when the motor rotates to the speed reducing device, and then the output shaft of the speed reducing device is connected with the pulsator, thereby driving the pulsator to rotate.
普通电机的转速较高,为了得到合适的输出转速,在实际应用中,需要对电机进行减速,常用的方式有使电机传递到减速器通过一级皮带轮减速,在减速器里设置一级或多级齿轮减速装置来完成一定速比的减速。此结构不仅复杂,而且占用空间大。为了解决此技术问题,目前已有一些关于去除皮带轮,将电机与减速器进行直接连接,由于其电机本体与减速器仍然是相对独立的,电机本体与减速器均分别需要占用安装空间,结构不够紧凑,体积仍然较大。The speed of the ordinary motor is high. In order to get the proper output speed, in the actual application, the motor needs to be decelerated. The common way is to make the motor transmit to the reducer and decelerate through the first pulley. Set one or more in the reducer. The stage gear reduction device is used to complete the deceleration of a certain speed ratio. This structure is not only complicated but also takes up a lot of space. In order to solve this technical problem, there have been some problems concerning the removal of the pulley and the direct connection between the motor and the reducer. Since the motor body and the reducer are still relatively independent, the motor body and the reducer respectively need to occupy the installation space, and the structure is insufficient. Compact and still large.
因此,如何设计一种结构紧凑、占用空间小的洗衣机驱动机构,是本领域技术人员需要解决的技术问题。Therefore, how to design a washing machine driving mechanism with compact structure and small space is a technical problem that a person skilled in the art needs to solve.
为了解决上述技术问题,结合本申请人在本领域的多年开发经验,本申请人在先申请了多项专利,如公开号为CN102677427A公开了一种洗衣机驱动器,包括电机、洗涤轴、套装在所述洗涤轴上的脱水轴套和齿轮减速机构,所述洗涤轴同轴安装于所述电机的电机转子内部且与所述齿轮减速机构的输出齿轮固接,所述齿轮减速机构的输入齿轮轴插装于所述电机转子的轴孔内。由于将齿轮减速机构的输入齿轮轴插装在电机转子的轴孔内,使电机转子作为齿轮减速机构的齿轮架,有效地将齿轮减速机构和电机集成为一体,从而减小了洗衣机驱动器的轴向尺寸,使得该洗衣机驱动器的结构简单紧凑,占用空间小。又如授权公开号为CN103422326B的中国发明专利公开了一种洗衣机驱动装置,其包括:用来提供转动动能的无转轴旋转体;安装在所述旋转体上的变速装置,用于从旋转体中心位置处获取转动动能,并输出其转速等 于或低于所述旋转体转速的动力;连接所述变速装置的洗涤轴和脱水轴套,在所述变速装置输出动力的作用下将所述等于或低于所述旋转体转速的动力分别供应给洗衣机的洗涤和脱水执行部件;其中,脱水轴套套设于洗涤轴外部与其转动连接,该发明的洗衣机驱动装置,其将变速装置安装在提供转动动能的旋转体内,因此压缩了整个驱动装置的体积,并且结构简单、紧凑,节省能源,噪声小。In order to solve the above technical problems, in conjunction with the applicant's many years of development experience in the field, the applicant has previously applied for a number of patents, such as the publication number CN102677427A, which discloses a washing machine driver, including a motor, a washing shaft, and a suit. a dewatering bushing and a gear reduction mechanism on the washing shaft, the washing shaft is coaxially mounted inside the motor rotor of the motor and fixed to an output gear of the gear reduction mechanism, and an input gear shaft of the gear reduction mechanism Inserted into the shaft hole of the rotor of the motor. Since the input gear shaft of the gear reduction mechanism is inserted into the shaft hole of the motor rotor, the motor rotor is used as the gear carrier of the gear reduction mechanism, and the gear reduction mechanism and the motor are effectively integrated into one body, thereby reducing the shaft of the washing machine driver. The size of the washing machine makes the structure of the washing machine simple and compact, and takes up little space. Further, as disclosed in Chinese Patent Publication No. CN103422326B, a washing machine driving apparatus includes: a shaftless rotating body for providing rotational kinetic energy; and a shifting device mounted on the rotating body for rotating from the center of the rotating body Acquiring the rotational kinetic energy at the position, and outputting the power whose rotational speed is equal to or lower than the rotational speed of the rotating body; connecting the washing shaft and the dewatering bushing of the shifting device, and the equalizing or The power lower than the rotational speed of the rotating body is respectively supplied to the washing and dehydrating executing part of the washing machine; wherein the dewatering sleeve is sleeved and connected to the outside of the washing shaft, the washing machine driving device of the invention, which installs the shifting device to provide rotational kinetic energy The rotating body thus compresses the volume of the entire driving device, and has a simple and compact structure, saves energy, and has low noise.
再如本申请人在先申请的公开号为CN103437126A的中国发明专利公开了一种洗衣机驱动机构以及洗衣机,包括电动机、与电动机连接的传动组件、离合组件和安装壳体,离合组件包括离合齿圈以及位于离合齿圈外部的电磁线圈机构;安装壳体包括定子安装盘和安装板,行星轮系位于定子安装盘和安装板固定连接形成的轮系腔体中,离合组件位于定子安装盘和电动机连接形成的电动机腔体中,其中,离合齿圈轴向滑动地套接在驱动轴套上与转子组件卡合连接或脱离,且其与转子组件脱离后处于非固定状态;达到结构简单、紧凑、体积小的目的。Further, the Chinese invention patent publication CN103437126A, which is hereby incorporated by reference by the same applicant, discloses a washing machine drive mechanism and a washing machine including an electric motor, a transmission assembly connected to the electric motor, a clutch assembly and a mounting housing, and the clutch assembly includes a clutch ring gear. And a solenoid mechanism located outside the clutch ring gear; the mounting housing includes a stator mounting plate and a mounting plate, wherein the planetary gear is located in a wheel system cavity formed by fixed connection between the stator mounting plate and the mounting plate, and the clutch assembly is located at the stator mounting plate and the motor The motor cavity formed by the connection, wherein the clutch ring gear is axially slidably sleeved on the drive bushing to be engaged or disengaged from the rotor assembly, and is detached from the rotor assembly in a non-fixed state; the structure is simple and compact Small size.
综上所述,本申请人的这些在先申请相对于现有技术在齿轮减速机构与电机之间连接的体积占用和结构紧凑度上对于洗衣机驱动领域带来了变革式的突破,然而本申请人的这些在先申请均是采用将变速机构或电磁离合机构整体安装在电机内,这就需要电机预留较大安装空间,不仅会导致电机尺寸大、耗材多、制造成本高,而且电机在设计、制造方面均存在较高难度,不适合应用于广大家庭使用的中低档的洗衣机领域。In summary, the applicant's prior application has revolutionized the field of washing machine drive with respect to the volume occupation and compactness of the connection between the gear reduction mechanism and the motor in the prior art, however, the present application These prior applications of the person are all installed in the motor by the shifting mechanism or the electromagnetic clutch mechanism. This requires a large installation space for the motor, which not only causes the motor to have large size, consumables, high manufacturing cost, but also the motor. Both design and manufacturing have high difficulty and are not suitable for use in the middle and low-end washing machines used by the majority of households.
而授权公告号为CN2443980Y的中国实用新型专利公开了一种无刷电机直接驱动的洗衣机减速离合器,采用永磁外转子无刷直流电机直接同轴安装在离合器输入轴的传矩轴套上,并固定于离合器壳体上,无刷电机轴又是离合器传矩轴;该技术淘汰皮带轮传动,使得离合器更加小型化。但由于该技术采用永磁外转子无刷直流电机,电机成本高,而且采用的离合器与转子的连接结构繁琐,同时离合器和制动机构分别采用拨杆和制动臂的独立结构,采用的连接部件多,连接复杂,成本高,结构不够紧凑,同样不太适合应用于广大家庭使用的中低档的洗衣机领域。The Chinese utility model patent with the authorization bulletin number CN2443980Y discloses a washing machine deceleration clutch directly driven by a brushless motor, which is directly coaxially mounted on the torque shaft sleeve of the clutch input shaft by a permanent magnet outer rotor brushless DC motor, and Fixed to the clutch housing, the brushless motor shaft is also the clutch transmission shaft; this technology eliminates the pulley drive, making the clutch more compact. However, since the technology adopts a permanent magnet outer rotor brushless DC motor, the motor cost is high, and the connection structure of the clutch and the rotor is complicated, and the clutch and the brake mechanism respectively adopt the independent structure of the lever and the brake arm, and the connection is adopted. It has many components, complicated connection, high cost and compact structure. It is also not suitable for the middle and low-end washing machines used by the majority of households.
因此,需要寻求一种洗衣机驱动系统,在既满足结构简单紧凑,占用空间小的条件下,同时成本低,连接部件少,制造工艺简单。Therefore, there is a need to find a washing machine drive system that satisfies both the simple and compact structure and the small footprint, at the same time low cost, few connecting parts, and simple manufacturing process.
发明内容Summary of the invention

当洗衣机在脱水工况时,外部牵引电机(图未示出)启动工作向拨杆321 施加牵引力,此时牵引力克服扭簧322的扭力,拨杆321带动棘刺323转动使得棘刺323的棘刺部323b与棘轮314脱离,拨杆321不再向棘轮314传输驱动力,使得原松开的旋丝弹簧313复位,即旋丝弹簧313处于锁紧状态,离合轴套311和输入轴套240处于单向锁定状态,与此同时,由于牵引力克服了扭簧322的扭力使得刹车带510松开输出轴套250,当PSC电机100往旋丝弹簧313锁定方向转动时,外转子组件110、输入轴220、行星轮系210和输出轴套250连接为一体,外转子组件110将旋转动力等速输出到内桶,内桶带动波轮一同高速旋转实现对洗涤物的脱水功能。When the washing machine is in the dehydrating condition, the external traction motor (not shown) starts to work to apply the traction force to the lever 321 . At this time, the traction force overcomes the torsion force of the torsion spring 322, and the lever 321 drives the ratchet 323 to rotate so that the spinous portion 323b of the spine 323 Disengaged from the ratchet 314, the lever 321 no longer transmits the driving force to the ratchet 314, so that the original loosened wire spring 313 is reset, that is, the wire spring 313 is in the locked state, and the clutch sleeve 311 and the input bushing 240 are in one direction. In the locked state, at the same time, since the traction force overcomes the torsion force of the torsion spring 322, the brake band 510 releases the output bushing 250, and when the PSC motor 100 rotates in the locking direction of the wire spring 313, the outer rotor assembly 110, the input shaft 220, The planetary gear train 210 and the output bushing 250 are integrally connected, and the outer rotor assembly 110 outputs the rotational power to the inner tub at a constant speed, and the inner bucket drives the pulsator to rotate at a high speed to realize the dehydrating function of the laundry.
当洗衣机完成脱水工况后,PSC电机100和外部牵引电机均停止工作,牵引力消失,扭簧322向拨杆321施加的扭力使得刹车带510再次抱紧输出轴套250,向输出轴套250施加制动力,快速降低内桶的转速,从而实现刹车的效果。When the washing machine completes the dehydration condition, both the PSC motor 100 and the external traction motor stop working, the traction force disappears, and the torsion force applied by the torsion spring 322 to the lever 321 causes the brake band 510 to once again grip the output sleeve 250 and apply to the output sleeve 250. Braking force, quickly reduce the speed of the inner barrel, thus achieving the effect of braking.

本实施方式提出的洗衣机,包括洗涤执行部件和脱水执行部件,以及洗衣机驱动系统,其中,洗衣机驱动系统采用如上实施方式所述的洗衣机驱动系统。The washing machine proposed in the present embodiment includes a washing execution unit and a dehydrating execution unit, and a washing machine drive system, wherein the washing machine drive system employs the washing machine drive system described in the above embodiment.
本具有拨叉组件630的洗衣机驱动系统的实施方式应用于洗衣机时的工作过程如下:The working process of the embodiment of the washing machine drive system having the shift fork assembly 630 applied to the washing machine is as follows:
当洗衣机在洗涤工况时,扭簧322向拨杆321施加的扭力形成驱动力,拨杆321的输出端通过插入拨杆插孔412内,通过拨杆套330驱动拨叉转盘631,拨叉转盘631通过滑动连接驱动第一棘刺633和第二棘刺634分别在安装轴635、636上转动,进而通过第一棘刺633的棘刺部633b与第一棘轮610的啮合以及第二棘刺634的棘刺部634b与第二棘轮620的啮合分别向第一棘轮610和第二棘轮620传输驱动力,该驱动力分别驱动挂设在第一棘轮610的卡口611内和第二棘轮620的卡口内的旋丝弹簧313两端同时被松开,离合轴套311和输入轴套240处于分离状态,与此同时,扭簧322向拨杆321施加的扭力使得其一端安装在拨杆321的安装端上且另一端安装在定子安装盘410上的刹车带510抱紧输出轴套250,使得输出轴套250处于抱紧固定状态,PSC电机100通过输入轴220将旋转动力传输至行星轮系210,通过依次啮合连接的太阳轮211、行星轮212、内齿圈213和行星架215,最终将旋转动力减速输出到波轮,通过波轮的反复运动实现对洗涤物的洗涤功能。When the washing machine is in the washing condition, the torsion force applied by the torsion spring 322 to the lever 321 forms a driving force, and the output end of the lever 321 is inserted into the lever insertion hole 412, and the fork dial 631 is driven by the lever sleeve 330. The turntable 631 drives the first spine 633 and the second ratchet 634 to rotate on the mounting shafts 635, 636 by the sliding connection, respectively, and the engagement of the ratchet portion 633b of the first ratchet 633 with the first ratchet 610 and the spine portion of the second ratchet 634 The engagement of the 634b with the second ratchet 620 transmits a driving force to the first ratchet 610 and the second ratchet 620, respectively, which drives the rotation of the first ratchet 610 and the second ratchet 620. The two ends of the wire spring 313 are simultaneously loosened, and the clutch sleeve 311 and the input bushing 240 are in a separated state. At the same time, the torsion force applied by the torsion spring 322 to the lever 321 is such that one end thereof is mounted on the mounting end of the lever 321 and The brake band 510 mounted on the stator mounting plate 410 at the other end holds the output bushing 250 so that the output bushing 250 is in a tightly fixed state, and the PSC motor 100 transmits the rotational power to the planetary gear train 210 through the input shaft 220, by Meshing Sun gear 211, planetary gear 212, ring gear 213 and the carrier 215, and finally decelerate the rotational power to the pulsator output, to achieve the laundry washing function by repeating the movement of the pulsator.
当洗衣机在脱水工况时,外部牵引电机启动工作向拨杆321施加牵引力,此时牵引力克服扭簧322的扭力,拨杆321带动拨叉转盘631转动,进而带动第一棘刺633和第二棘刺634转动,使得第一棘刺633的棘刺部633b与第一棘轮610脱离以及第二棘刺634的棘刺部634b与第二棘轮620脱离,拨杆321不再向第一棘轮610和第二棘轮620传输驱动力,使得原两端松开的旋丝弹簧313复位,即旋丝弹簧313处于锁紧状态,离合轴套311和输入轴套240处于单向锁定状态,与此同时,由于牵引力克服了扭簧322的扭力使得刹车带510松开输出轴套250,当PSC电机100往旋丝弹簧313锁定方向转动时,外转子组件110、输入轴220、行星轮系210和输出轴套250连接为一体,外转子组件110将旋转动力等速输出到内桶,内桶带动波轮一同高速旋转实现对洗涤物的脱水功能。When the washing machine is in the dehydrating condition, the external traction motor starts to work to apply the traction force to the lever 321 . At this time, the traction force overcomes the torsion force of the torsion spring 322, and the lever 321 drives the fork dial 631 to rotate, thereby driving the first ratchet 633 and the second ratchet. The rotation of 634 causes the spinous portion 633b of the first spine 633 to disengage from the first ratchet 610 and the ratchet portion 634b of the second spine 634 to disengage from the second ratchet 620, and the lever 321 is no longer transmitted to the first ratchet 610 and the second ratchet 620. The driving force is such that the original two ends of the loosened wire spring 313 are reset, that is, the wire spring 313 is in a locked state, and the clutch sleeve 311 and the input bushing 240 are in a one-way locked state, and at the same time, the traction force overcomes the twist The torque of the spring 322 causes the brake band 510 to release the output bushing 250. When the PSC motor 100 rotates in the locking direction of the wire spring 313, the outer rotor assembly 110, the input shaft 220, the planetary gear train 210 and the output bushing 250 are integrally connected. The outer rotor assembly 110 outputs the rotational power to the inner tub at a constant speed, and the inner bucket drives the pulsator to rotate at a high speed to realize the dehydration function of the laundry.

The embodiment has the advantages of simple structure and convenient control, and the double-spindle double-spindle engagement transmission clutching mode realizes loosening of both ends of the wrap spring assembly 312", which can further effectively ensure the accuracy of switching the clutch state.
