Description

洗衣机washing machine 技术领域Technical field
本发明涉及一种可以抑制洗涤脱水槽旋转时的振动的洗衣机。The present invention relates to a washing machine capable of suppressing vibration when a washing and dewatering tank is rotated.
背景技术Background technique
目前,通常已知有如下结构的洗衣机,即,在形成为箱状的主体的内部支承有底圆筒状的外槽,在该外槽的内侧可旋转地支承作为内槽的洗涤脱水槽(例如参照专利文献1)。At present, a washing machine having a structure in which a cylindrical outer tank is supported inside a main body formed in a box shape and a washing and dewatering tank as an inner tank is rotatably supported inside the outer tank ( For example, refer to Patent Document 1).
在这样的一般的洗衣机中,经由包含弹簧而构成的悬架和吊挂其的吊棒将外槽在四个部位弹性支承于主体上,由此抑制动作时的振动。In such a general washing machine, the outer groove is elastically supported on the main body at four locations via a suspension including a spring and a hanger hanging thereon, thereby suppressing vibration during operation.
在设为这种结构的情况下,外槽绕洗涤脱水槽的旋转轴振动的振动方式的低次固有振动数在比洗涤脱水槽的旋转速度低的区域出现。具体而言,在洗涤脱水槽的底部设置波轮(搅拌翼),在脱水时在外槽的内部使洗涤脱水槽和波轮一体地高速旋转。在开始洗涤脱水槽的旋转使其增速的过程中,如果洗涤脱水槽的旋转速度与上述低次固有振动数一致,则振动暂时增大。随着进一步提高洗涤脱水槽的旋转速度,脱离低次固有振动数,振动减小,可以在所设定的旋转速度下稳定地动作。In the case of such a configuration, the number of low-order natural vibrations of the vibration mode in which the outer groove vibrates around the rotation axis of the washing and dewatering tank occurs in a region lower than the rotation speed of the washing and dewatering tank. Specifically, a pulsator (agitating blade) is provided at the bottom of the washing and dewatering tank, and the washing and dewatering tank and the pulsator are integrally rotated at a high speed inside the outer tank at the time of dehydration. When the rotation of the washing and dewatering tank is started to increase the speed, if the rotation speed of the washing and dewatering tank coincides with the number of the low-order natural vibrations described above, the vibration temporarily increases. As the rotation speed of the washing and dewatering tank is further increased, the number of low-order natural vibrations is removed, and the vibration is reduced, so that the rotation speed can be stably operated at the set rotation speed.
但是,也认为在进入洗涤脱水槽的洗涤物有偏倚,绕旋转轴的不平衡量大的情况下,外槽的振动增大,特别是在低次固有振动数下,外槽大幅振动并与主体的内部抵接。而且,由于洗衣机整体产生大的噪音、振动,从而洗衣机的设置场所周围的环境恶化,并且可能损伤构成洗衣机的部件。However, it is also considered that when the laundry entering the washing and dewatering tank is biased and the amount of unwinding around the rotating shaft is large, the vibration of the outer tank is increased, particularly in the case of low-order natural vibration, the outer tank vibrates greatly and the main body The internal abutment. Moreover, since the washing machine as a whole generates large noise and vibration, the environment around the installation place of the washing machine is deteriorated, and the components constituting the washing machine may be damaged.
为抑制上述的不良,通常考虑使外槽和主体之间具有一定以上的间隙来减少外槽和主体的碰撞。另外,还考虑在检测到过大的振动时进行停止旋转、或纠正洗涤物的偏倚的控制。In order to suppress the above-mentioned defects, it is generally considered to have a certain gap between the outer groove and the main body to reduce the collision between the outer groove and the main body. In addition, it is also considered to control the rotation to stop or correct the deviation of the laundry when an excessive vibration is detected.
但是,在使外槽和主体之间具有一定以上的间隙的情况下,与主体相比,不得不使外槽小型化,在主体内部需要大的死区。另外,在通过控制来进行振动对策的情况下,需要振动检测装置及复杂的控制,导致成本增大。However, when there is a certain gap or more between the outer tub and the main body, the outer tub has to be miniaturized as compared with the main body, and a large dead zone is required inside the main body. Further, when the vibration countermeasure is performed by the control, the vibration detecting device and the complicated control are required, resulting in an increase in cost.
因此,为解决上述问题,考虑使用下述专利文献2记载的技术。专利文献2中公开有如下结构,即,在使洗衣机的外槽的外侧拥有余隙的状态下同轴配置 环,且在该环的外侧设置板簧(参照段落0094、0095及图19D、19E)。该板簧在预先赋予加压使其位移的状态下由止动件保持,在位移至其以上而止动件的限制消失的情况下,可以作用包含加压量的大的弹簧力。Therefore, in order to solve the above problem, it is conceivable to use the technique described in Patent Document 2 below. Patent Document 2 discloses a configuration in which a coaxial configuration is performed in a state where a clearance is provided outside the outer tank of the washing machine. A ring is provided on the outer side of the ring (see paragraphs 0094, 0095 and Figs. 19D, 19E). The leaf spring is held by the stopper in a state where the pressure is applied to the displacement in advance, and when the displacement is shifted to the above and the restriction of the stopper disappears, a large spring force including the amount of pressurization can be applied.
因此,专利文献2记载的技术中,在洗涤脱水槽的旋转速度接近低次固有振动数,外槽大幅振动并与环抵接时,外槽为不仅由包含于上述悬架的弹簧弹性支承,而且还由设于环上的板簧弹性支承的状态,通过低次固有振动数变化,可以降低振动。Therefore, in the technique described in Patent Document 2, when the rotational speed of the washing and dewatering tank is close to the number of low-order natural vibrations, and the outer tank vibrates largely and abuts against the ring, the outer groove is elastically supported not only by the spring included in the suspension, Further, the state in which the leaf spring provided on the ring is elastically supported can reduce the vibration by changing the number of low-order natural vibrations.

发明所要解决的课题Problem to be solved by the invention
为了实现洗衣机的轻型化和制造成本的减少,外槽一般多以树脂形成。因此,在与上述专利文献2那样的结构组合的情况下,可能会导致洗衣机的外槽由于与环状体接触而被磨耗、损伤。进而,洗衣机的外槽具备形成用于赋予强度的筋、布线和/或配管的安装部等的设计自由度,大多结合要求式样使外周面制成复杂的形状。然而,在采用上述专利文献2的结构的情况下,为了让外槽的外圆周和环状体可以顺利地接触,因为外槽的外周面的形状被限定为圆形所以降低了设计自由度,增大了开发成本。In order to reduce the weight of the washing machine and reduce the manufacturing cost, the outer tank is generally formed of a resin. Therefore, in the case of combining with the structure of the above-mentioned Patent Document 2, the outer tub of the washing machine may be worn and damaged due to contact with the annular body. Further, the outer tub of the washing machine has a degree of freedom in designing a mounting portion for forming a rib, a wiring, and/or a pipe for imparting strength, and the outer peripheral surface is often formed into a complicated shape in combination with a required pattern. However, in the case of adopting the configuration of Patent Document 2 described above, in order to allow the outer circumference of the outer groove and the annular body to be smoothly contacted, since the shape of the outer peripheral surface of the outer groove is limited to a circular shape, the degree of freedom in design is lowered. Increased development costs.

发明效果Effect of the invention
根据以上说明的本发明,在通过电机使内槽旋转时,当通过使旋转速度接近外槽的固有振动数从而使外槽大幅度地回旋时,通过设置于外槽的外圆周上的弹性体与主体内部接触,从而能使固有振动数变化从而减少振动。According to the invention as described above, when the inner groove is rotated by the motor, when the outer groove is largely rotated by bringing the rotation speed close to the natural vibration number of the outer groove, the elastic body provided on the outer circumference of the outer groove It is in contact with the inside of the main body, so that the natural vibration number can be changed to reduce the vibration.
具体地说,外槽回旋的振动方式的固有振动数依赖于支承外槽的弹性支承装置的弹性支承强度(弹簧常数),通过旋转速度接近该固有振动数从而使外槽以大幅度地回旋的方式振动,设置于外槽的外圆周的弹性体与主体内部接触。弹性体通过位移限制装置以给予加压的状态被限制,当弹性体与主体内部接触而被压缩时,通过解除位移限制装置的限制从而使外槽的弹性支承强度急剧变化,能使外槽的固有振动数变化。因此,能减小外槽的振动,将内槽进而加速到规定的旋转频率。Specifically, the number of natural vibrations of the vibration mode of the outer groove swirl depends on the elastic support strength (spring constant) of the elastic support device supporting the outer groove, and the outer groove is largely swirled by the rotation speed close to the natural vibration number. In a vibrating manner, the elastic body provided on the outer circumference of the outer groove is in contact with the inside of the main body. The elastic body is restricted by the displacement restricting means to give a pressurized state. When the elastic body is compressed in contact with the inside of the main body, the elastic support strength of the outer groove is sharply changed by releasing the restriction of the displacement restricting means, so that the outer groove can be made The number of natural vibrations changes. Therefore, the vibration of the outer groove can be reduced, and the inner groove can be further accelerated to a predetermined rotation frequency.
这样,能在振幅变得过大之前减少起因于外槽的固有振动数的振动,能将内槽增速到规定的旋转速度,因此能防止噪声和振动,抑制设置场所的环境恶 化。进而,因为弹性体设置于外槽,所以能防止外槽的损伤,也可以更加提高工作的稳定性。此外,由于仅通过能安装弹性体,从而较高地维持外槽的外表面的设计自由度,所以也不会导致开发成本的增大。In this way, the vibration caused by the natural vibration number of the outer groove can be reduced before the amplitude becomes excessively large, and the inner groove can be increased to a predetermined rotation speed. Therefore, noise and vibration can be prevented, and the environmental evil at the installation place can be suppressed. Chemical. Further, since the elastic body is provided in the outer groove, damage to the outer groove can be prevented, and the stability of the operation can be further improved. Further, since the design freedom of the outer surface of the outer tank is maintained high only by the fact that the elastic body can be attached, the development cost is not increased.
特别是,根据将弹性体沿着第一方向以及第二方向设置的本发明,因为以在相互交叉的两个方向上分别夹着外槽的方式至少一对一对地配置弹性体,所以使主体内表面和弹性体的另一端的间隙的管理变得容易,使设计自由度提高,同时可以使经由弹性体使外槽和弹性体接触的结构容易实现。In particular, according to the present invention in which the elastic body is provided along the first direction and the second direction, since the elastic body is disposed at least in a pair so as to sandwich the outer grooves in the two directions intersecting each other, The management of the gap between the inner surface of the main body and the other end of the elastic body is facilitated, the degree of freedom in design is improved, and the structure in which the outer groove and the elastic body are brought into contact via the elastic body can be easily realized.
特别是,根据将弹性体接近内部空间的角落部地设置的本发明,通过将弹性体接近形成为大致长方体状的内部空间的角落部地设置,从而能有效地利用易变为无用空间的内部空间和外槽之间的空间,可以更加实现小型化。进而,不仅在外槽进行回旋振动的情况下,即使在向旋转方向位移的情况下,也因为可以使弹性体的另一端与主体的内表面抵接,所以在外槽起因于电机的旋转不均或转矩变动而向旋转方向振动时也能适当地抑制振动。In particular, according to the present invention in which the elastic body is provided close to the corner portion of the internal space, by providing the elastic body close to the corner portion of the internal space formed into a substantially rectangular parallelepiped shape, it is possible to effectively utilize the interior which is easy to become a useless space. The space between the space and the outer groove can be further miniaturized. Further, in the case where the outer groove is subjected to the whirling vibration, even when the outer ring is displaced in the rotational direction, the other end of the elastic body can be brought into contact with the inner surface of the main body, so that the outer groove is caused by the uneven rotation of the motor or When the torque fluctuates and vibrates in the rotational direction, the vibration can be appropriately suppressed.
此外,根据设置凸状的抵接部和与其对置的被抵接部的本发明,在弹性体的另一端设置凸状的抵接部,并且在主体的内表面设置以经过其前端并与内槽的旋转轴平行的轴心为中心的圆弧状的被抵接部,通过使这些抵接部和被抵接部对置,从而在产生外槽的回旋振动时能顺利地使抵接部与被抵接部接触,因此可以使振动适当地减少。Further, according to the present invention in which the convex abutting portion and the abutted portion opposed thereto are provided, a convex abutting portion is provided at the other end of the elastic body, and is disposed on the inner surface of the main body to pass through the front end thereof and When the abutting portion and the contacted portion are opposed to each other, the abutting portion and the abutted portion are opposed to each other with the axis of rotation of the inner groove parallel to the axis of the axis, and the abutting portion of the inner groove can smoothly abut The portion is in contact with the abutted portion, so that the vibration can be appropriately reduced.
进而,根据设置形成为圆弧状的抵接部和与其对置的被抵接部的本发明,在弹性体的另一端设置圆弧状的抵接部,并且在主体的内表面设置抵接部和呈同心圆弧状的被抵接部,使抵接部和被抵接部对置,由此能在产生外槽的回旋振动时顺利地使抵接部和被抵接部抵接,因此可以使振动适当地减低。Further, according to the present invention in which the abutting portion formed in an arc shape and the abutted portion opposed thereto are provided, an arc-shaped abutting portion is provided at the other end of the elastic body, and the inner surface of the main body is provided with abutting The abutting portion and the abutted portion having the concentric arc shape are opposed to each other, whereby the abutting portion and the abutted portion can be smoothly contacted when the whirling vibration of the outer groove occurs. Therefore, the vibration can be appropriately reduced.
特别是,根据对抵接部连接至少两个弹性体的另一端的本发明,通过根据外槽的位移方向的变化顺利地切换作用的弹性体,可以使振动更适当地减少。In particular, according to the present invention in which the other end of the at least two elastic bodies is connected to the abutting portion, the vibration can be more appropriately reduced by smoothly switching the acting elastic body in accordance with the change in the displacement direction of the outer groove.

外槽3由具备耐热性的合成树脂成型,为具有俯视下大致圆形的底板31和从底板31的缘部立起的侧板32的有底圆筒状的部件。外槽3通过弹性支承装置5在主体2的内部空间2a吊挂,且在侧板32的下部的四个部位具备用于安装弹性支承装置5的卡合部33。The outer tub 3 is molded of a heat-resistant synthetic resin, and is a bottomed cylindrical member having a bottom plate 31 that is substantially circular in plan view and a side plate 32 that rises from the edge of the bottom plate 31. The outer tub 3 is suspended by the elastic support device 5 in the inner space 2a of the main body 2, and the engaging portion 33 for attaching the elastic supporting device 5 is provided at four portions of the lower portion of the side plate 32.
洗涤脱水槽4由金属形成,为具有俯视下大致圆形的底板41和从底板41的缘部立起的侧板42的有底圆筒状的部件。洗涤脱水槽4在外槽3的内部与该外槽3同轴配置,并且由外槽3旋转自如地支承。在侧板42及底板41上设置未图示的多个开口,可通过该开口排出洗涤脱水槽4内的水。The washing and dewatering tank 4 is made of metal and is a bottomed cylindrical member having a bottom plate 41 that is substantially circular in plan view and a side plate 42 that rises from the edge of the bottom plate 41. The washing and dewatering tank 4 is disposed coaxially with the outer tank 3 inside the outer tank 3, and is rotatably supported by the outer tank 3. A plurality of openings (not shown) are provided in the side plates 42 and the bottom plate 41, and the water in the washing and dewatering tank 4 can be discharged through the openings.
洗涤脱水槽4通过电机34使朝向底板31的上面侧延伸的驱动轴35旋转而进行旋转。另外,电机34产生的旋转力经由未图示的传递装置也向设于洗涤脱水槽4的底板41中央的波轮(搅拌翼)43赋予驱动力,使波轮43旋转。因此,洗衣机1可以在洗涤时主要仅使波轮43旋转,在脱水时使洗涤脱水槽4和波轮43一体地高速旋转。The washing and dewatering tank 4 is rotated by the motor 34 to rotate the drive shaft 35 that extends toward the upper surface side of the bottom plate 31. In addition, the rotational force generated by the motor 34 also applies a driving force to the pulsator (agitating blade) 43 provided at the center of the bottom plate 41 of the washing and dewatering tank 4 via a transmission device (not shown) to rotate the pulsator 43. Therefore, the washing machine 1 can mainly rotate only the pulsator 43 at the time of washing, and the washing and dewatering tank 4 and the pulsator 43 can be integrally rotated at high speed during dehydration.
波轮43的旋转的中心和洗涤脱水槽4的旋转的中心设定为与Z轴平行的同一旋转轴Ra。此外,旋转轴Ra也通过洗涤脱水槽4的底板41的中心、及外槽3的底板31的中心。The center of the rotation of the pulsator 43 and the center of the rotation of the washing and dewatering tank 4 are set to the same rotation axis Ra parallel to the Z axis. Further, the rotation axis Ra also passes through the center of the bottom plate 41 of the washing and dewatering tank 4 and the center of the bottom plate 31 of the outer tank 3.
弹性支承装置5~5悬挂外槽3。本实施方式中,弹性支承装置5~5设置四个,分别由吊棒51和安装于其前端的悬架52构成。悬架52具有外筒53和配置于其内部的压缩螺旋弹簧54。在主体2上,在其内部空间2a的四角2a1~2a1(参照图2)的上板23附近分别设置吊棒安装部24~24,且在各吊棒安装部24~24安装吊棒51的基端侧。进而,悬架52的外筒53在钩挂于上述外槽3的卡合部33的形式下与该卡合部33卡合。这样,外槽3通过四个弹性支承装置5~5在内部空间2a内吊挂。The elastic support devices 5 to 5 suspend the outer groove 3. In the present embodiment, four elastic support devices 5 to 5 are provided, and each of them is composed of a boom 51 and a suspension 52 attached to the front end thereof. The suspension 52 has an outer cylinder 53 and a compression coil spring 54 disposed inside thereof. In the main body 2, the boom attachment portions 24 to 24 are provided in the vicinity of the upper plate 23 of the four corners 2a1 to 2a1 (see FIG. 2) of the internal space 2a, and the boom 51 is attached to each of the boom attachment portions 24 to 24. Base side. Further, the outer cylinder 53 of the suspension 52 is engaged with the engaging portion 33 in a form of being caught by the engaging portion 33 of the outer tub 3. Thus, the outer tub 3 is suspended in the inner space 2a by the four elastic supporting means 5 to 5.
各弹性支承装置5的压缩螺旋弹簧54通过外槽3的重量压缩,产生反作用力,并且,在吸收位移的同时,弹性支承外槽3。另外,四个弹性支承装置5~5分别从斜方向吊挂外槽3,由此协动地实现用于使外槽3位于主体2的中央方向的保持平衡的作用。The compression coil spring 54 of each elastic supporting device 5 is compressed by the weight of the outer groove 3 to generate a reaction force, and elastically supports the outer groove 3 while absorbing the displacement. Further, the four elastic supporting devices 5 to 5 respectively suspend the outer tub 3 from the oblique direction, thereby cooperatively achieving the function of maintaining the balance of the outer tub 3 in the center direction of the main body 2.
即,弹性支承装置5不仅能获得悬架52的压缩螺旋弹簧54的弹性,而且还可以通过其位置关系,获得使吊挂的外槽3恰如振子那样返回中心的恢复力。因此,外槽3在从中心位置在x方向或y方向位移的情况下,由弹性支承装置5 得到与其位移量相对应的恢复力,并通过该恢复力返回主体2的中心位置。That is, the elastic supporting device 5 can obtain not only the elasticity of the compression coil spring 54 of the suspension 52 but also the restoring force for returning the center of the suspended outer groove 3 just like the vibrator by its positional relationship. Therefore, the outer groove 3 is displaced by the elastic support device 5 in the case of displacement from the center position in the x direction or the y direction. A restoring force corresponding to the displacement amount is obtained, and is returned to the center position of the main body 2 by the restoring force.
在此,如上述,通过利用弹性支承装置5弹性地支承外槽3,与外槽3绕旋转轴Ra回旋的振动方式相对应的低次固有振动数在约2~3Hz程度的非常低的旋转速度区域出现。洗衣机1中最容易产生振动的是洗涤脱水槽4与波轮43一同高速旋转的情况,通常,虽然以比上述低次固有振动数充分高的规定的运转速度旋转,但在起动后到升速的过程、或从上述运转速度减速的过程中,在洗涤脱水槽4的旋转速度与低次固有振动数一致或接近的情况下,外槽3以绕旋转轴Ra回旋的方式大幅振动。另外,在进入洗涤脱水槽4的内部的洗涤物有偏倚的情况下,其成为绕旋转轴Ra的不平衡,加振力增加,外槽3的振动进一步增大。Here, as described above, by elastically supporting the outer tub 3 by the elastic supporting device 5, the number of low-order natural vibrations corresponding to the vibration mode in which the outer tub 3 is swung around the rotation axis Ra is very low rotation of about 2 to 3 Hz. The speed zone appears. The most likely vibration in the washing machine 1 is that the washing and dewatering tank 4 rotates at a high speed together with the pulsator 43. Usually, the washing dewatering tank 4 rotates at a predetermined operating speed that is sufficiently higher than the number of low-order natural vibrations, but after starting, the speed is increased. In the process of decelerating from the above-described operation speed, when the rotational speed of the washing and dewatering tank 4 coincides with or is close to the number of low-order natural vibrations, the outer tank 3 vibrates largely around the rotation axis Ra. Further, when the laundry entering the inside of the washing and dewatering tank 4 is biased, it becomes an imbalance around the rotation axis Ra, the vibration force increases, and the vibration of the outer tank 3 further increases.
因此,本实施方式的洗衣机1(1A)为了将外槽3的振动抑制得较小,如图1、图2所示,在构成外槽3的侧板32的外表面32a的上部附近的多个位置处配置第二弹性支承装置6。更具体地说,洗衣机1(1A)具备:沿着作为与旋转轴Ra交叉的第一方向的x方向配置,设置成夹着外槽3的一对x方向弹性支承装置6x、6x;以及沿着作为与旋转轴Ra以及第一方向交叉的第二方向的y方向配置,设置成夹着外槽3的一对y方向弹性支承装置6y、6y。这些弹性支承装置6x、6y在俯视时配置为以旋转轴Ra为中心的十字型,分别与构成主体2的侧板21~21对置。以下,在根据配置的方向需要区分时,称为x方向弹性支承装置6x或者y方向弹性支承装置6y,在不需要根据方向进行区别时将这些总体上称为第二弹性支承装置6。Therefore, the washing machine 1 (1A) of the present embodiment suppresses the vibration of the outer tub 3 to a small extent, as shown in Figs. 1 and 2, in the vicinity of the upper portion of the outer surface 32a of the side plate 32 constituting the outer tub 3. The second elastic support device 6 is disposed at each position. More specifically, the washing machine 1 (1A) is provided with a pair of x-direction elastic supporting means 6x, 6x disposed along the x-direction as a first direction crossing the rotation axis Ra, and sandwiching the outer groove 3; The pair of y-direction elastic supporting devices 6y and 6y that sandwich the outer groove 3 are disposed in the y direction as the second direction intersecting the rotation axis Ra and the first direction. The elastic supporting devices 6x and 6y are disposed in a cross shape centered on the rotating shaft Ra in plan view, and face the side plates 21 to 21 constituting the main body 2, respectively. Hereinafter, when it is necessary to distinguish according to the direction of the arrangement, it is referred to as the x-direction elastic supporting device 6x or the y-direction elastic supporting device 6y, and these are collectively referred to as the second elastic supporting device 6 when it is not necessary to distinguish them according to the direction.
图3(a)为放大示出了第二弹性支承装置6的俯视图。第二弹性支承装置6由作为弹性体的压缩螺旋弹簧61、安装于压缩螺旋弹簧61的一端61a的块状的基端构件63、安装于另一端61b的板状的前端构件64、以及作为给压缩螺旋弹簧61给予加压的位移限制装置的限制绳62构成。基端构件63作为用于在外槽3的外表面32a安装压缩螺旋弹簧61的安装构件发挥功能。前端构件64在构成主体2的侧板21的内表面21a之间带有规定的间隙E,在外槽3更进一步位移的情况下前端构件64与主体2的内表面21a抵接。即,前端构件64作为用于与主体2的内表面21a抵接的抵接部发挥功能。通过这样,压缩螺旋弹簧61通过基端构件63使一端61a与外槽3的外表面连接,另一端61b隔着间隙E与主体2的内表面21a对置。Fig. 3(a) is a plan view showing the second elastic supporting device 6 in an enlarged manner. The second elastic supporting device 6 is composed of a compression coil spring 61 as an elastic body, a block-shaped base end member 63 attached to one end 61a of the compression coil spring 61, a plate-shaped distal end member 64 attached to the other end 61b, and The compression coil spring 61 is constituted by a restriction cord 62 of a pressurized displacement restricting device. The proximal end member 63 functions as a mounting member for attaching the compression coil spring 61 to the outer surface 32a of the outer tub 3. The distal end member 64 has a predetermined gap E between the inner surfaces 21a of the side plates 21 constituting the main body 2, and when the outer grooves 3 are further displaced, the distal end members 64 abut against the inner surface 21a of the main body 2. That is, the distal end member 64 functions as an abutting portion for abutting against the inner surface 21a of the main body 2. Thus, the compression coil spring 61 connects the one end 61a to the outer surface of the outer tub 3 via the proximal end member 63, and the other end 61b faces the inner surface 21a of the main body 2 via the gap E.
图3(b)为说明构成第二弹性支承装置6的压缩螺旋弹簧61和作为位移限 制装置的限制绳62的关系的说明图。Figure 3 (b) is a view showing the compression coil spring 61 constituting the second elastic supporting means 6 and as a displacement limit An explanatory view of the relationship of the restriction cord 62 of the manufacturing apparatus.
压缩螺旋弹簧61如图3(b)所示,从自然长度L的状态(图3(b)上段)变为通过赋予加压Fp而压缩ΔL的状态(图3(b)中段)。在该状态下,当安装经过压缩螺旋弹簧61的中央、连结基端构件63和前端构件64之间的限制绳62时,限制位移使得压缩螺旋弹簧61不进而伸长。但是,由于限制绳62具有挠性,压缩螺旋弹簧61以给予了上述加压Fp的状态为基准允许向压缩方向位移(图3(b)下段)。As shown in FIG. 3(b), the compression coil spring 61 changes from a state of the natural length L (upper stage of FIG. 3(b)) to a state of compressing ΔL by applying the pressure Fp (middle of FIG. 3(b)). In this state, when the center of the compression coil spring 61 is attached and the restriction cord 62 between the joint end member 63 and the front end member 64 is attached, the displacement is restricted so that the compression coil spring 61 is not further elongated. However, since the restriction cord 62 has flexibility, the compression coil spring 61 is allowed to be displaced in the compression direction with reference to the state in which the above-described pressure Fp is given (Fig. 3(b) lower stage).
图4(a)、(b)示意性表示本实施方式的洗衣机1的构造。下面,参照图1,使用图4(a)、(b)说明作用于洗衣机1的外槽3的力。4(a) and 4(b) schematically show the structure of the washing machine 1 of the present embodiment. Next, the force acting on the outer tub 3 of the washing machine 1 will be described with reference to Fig. 1 using Figs. 4(a) and 4(b).
首先,外槽3通过由上述的四个弹性支承装置5~5吊挂,根据从中心的位移e产生用于使外槽3返回中心的恢复力k·e。在此,k是将由弹性支承装置5~5在中心方向作用的恢复力看作是弹力的情况(参照图4(a))的弹簧常数。First, the outer tub 3 is suspended by the above-described four elastic supporting devices 5 to 5, and a restoring force k·e for returning the outer tub 3 to the center is generated in accordance with the displacement e from the center. Here, k is a spring constant in a case where the restoring force acting in the center direction by the elastic supporting devices 5 to 5 is regarded as an elastic force (see FIG. 4( a )).
另外,在设外槽3的质量为M,外槽3绕离开重心位置Cg距离(位移)e的旋转中心Cr进行回旋运动的情况下,产生朝向外径方向的惯性力(离心力)M·ω2·e。在此,ω是外槽3回旋时的角频率,与洗涤脱水槽4旋转时的角频率ω相等。另外,在将洗涤脱水槽4(参照图2)那样的外槽3的内部的旋转部分的不平衡设为Δm,将距旋转中心Cr的距离设为r时,该不平衡引起的惯性力(离心力)为Δm·r·ω2Further, when the mass of the outer tank 3 is M and the outer tank 3 is rotated about the center of rotation Cr of the distance (displacement) e from the center of gravity Cg, an inertial force (centrifugal force) M·ω toward the outer diameter direction is generated. 2 ·e. Here, ω is an angular frequency when the outer tub 3 is rotated, and is equal to the angular frequency ω when the washing and dewatering tank 4 is rotated. In addition, when the imbalance of the rotating portion inside the outer tub 3 such as the washing and dewatering tank 4 (see FIG. 2) is Δm, and the distance from the center of rotation Cr is r, the inertia force due to the imbalance ( The centrifugal force) is Δm·r·ω 2 .
因此,在从这些考虑到力的均衡的情况下,得到下式的关系。Therefore, in the case of considering the balance of forces from these, the relationship of the following formula is obtained.
M·ω2·e+Δm·r·ω2=k·e···式(1)M·ω 2 ·e+Δm·r·ω 2 =k·e···(1)
将其变形后,得到下式。After deforming it, the following formula is obtained.
e=Δm·r·ω2/(M·ω2-k)···式(2)e=Δm·r·ω 2 /(M·ω 2 -k)···(2)
根据式(2),在成为满足M·ω2-k=0的旋转速度的情况下,位移e极大,即成为振动增大的共振状态。According to the formula (2), when the rotational speed satisfying M·ω 2 -k=0 is satisfied, the displacement e is extremely large, that is, the resonance state in which the vibration is increased.
另外,如果将式(1)的左边产生的力设为惯性力Fi、将右边产生的弹簧力设为Fk,则可以如下表示。Further, if the force generated on the left side of the equation (1) is the inertia force Fi and the spring force generated on the right side is Fk, it can be expressed as follows.
Fi=M·ω2·e+Δm·r·ω2···式(3)Fi=M·ω 2 ·e+Δm·r·ω 2 ···(3)
Fk=k·e···式(4)Fk=k·e···(4)
图5是将振幅(位移)e设为横轴,将包含惯性力Fi或弹簧力Fk的振动力F设为纵轴来表示上式的关系的图表。图中所示的直线L1~L10是表示式(3)的关系的惯性特性直线,直线La是表示式(4)的关系的弹簧特性直线,它们 的交点表示角频率ω时的振幅(位移)e和振动力F。FIG. 5 is a graph showing the relationship between the above equation with the amplitude (displacement) e being the horizontal axis and the vibration force F including the inertial force Fi or the spring force Fk being the vertical axis. The straight lines L1 to L10 shown in the drawing are inertial characteristic straight lines indicating the relationship of the formula (3), and the straight line La is a spring characteristic straight line indicating the relationship of the formula (4), and they are straight lines. The intersection point represents the amplitude (displacement) e and the vibration force F at the angular frequency ω.
就惯性特性直线L1~L10而言,斜率与角频率ω的平方成比例,与横轴的切片(交点)由Δm·r/M表示。惯性特性直线L1~L10分别以使角频率ω的大小不同的方式记载,表示的是随着角频率ω增大,从直线L1起如L2、L3、···L10那样振幅e和惯性力Fi的关系发生变化。因此,各惯性特性直线L1~L10和弹簧特性直线La的交点示出每角频率ω的振幅e和振动力F的关系。In the inertial characteristic lines L1 to L10, the slope is proportional to the square of the angular frequency ω, and the slice (intersection) on the horizontal axis is represented by Δm·r/M. The inertial characteristic lines L1 to L10 are described so that the magnitude of the angular frequency ω is different, and the amplitude e and the inertial force Fi such as L2, L3, ... L10 are increased from the straight line L1 as the angular frequency ω increases. The relationship has changed. Therefore, the intersection of each of the inertial characteristic straight lines L1 to L10 and the spring characteristic straight line La shows the relationship between the amplitude e of each angular frequency ω and the vibration force F.
使洗涤脱水槽4(参照图1)起动,在考虑角频率ω增大的过程的情况下,振幅e和振动力F如下变化。When the washing and dewatering tank 4 (refer to FIG. 1) is started, the amplitude e and the vibration force F are changed as follows in consideration of the process of increasing the angular frequency ω.
首先,在成为与惯性直线L1相对应的角频率ω的情况下,产生与惯性特性直线L1和弹簧特性直线La的交点P1相对应的振幅e和振动力F。在角频率ω增大,变为与惯性特性直线L2相对应的情况下,产生与惯性特性直线L2和弹簧特性直线La的交点P2相对应的振幅e和振动力F。进而,在角频率ω增大,变为与惯性特性直线L3相对应的情况下,产生与惯性特性直线L3和弹簧特性直线La的交点P3相对应的振幅e和振动力F。在角频率ω从该状态进一步增大并欲过渡到惯性直线L4的状态的情况下,与和惯性特性直线La的交点相对应的振幅e非常大。First, when the angular frequency ω corresponding to the inertia line L1 is obtained, the amplitude e and the vibration force F corresponding to the intersection P1 of the inertia characteristic line L1 and the spring characteristic line La are generated. When the angular frequency ω increases and corresponds to the inertia characteristic line L2, the amplitude e and the vibration force F corresponding to the intersection P2 of the inertia characteristic line L2 and the spring characteristic line La are generated. Further, when the angular frequency ω is increased to correspond to the inertia characteristic line L3, the amplitude e and the vibration force F corresponding to the intersection P3 of the inertia characteristic line L3 and the spring characteristic line La are generated. In the case where the angular frequency ω is further increased from this state and it is desired to transition to the state of the inertia line L4, the amplitude e corresponding to the intersection with the inertia characteristic line La is extremely large.
然而,如上所述,在本实施方式中,因为在外槽3和主体2之间存在间隙E并设置第二弹性支承装置6(参照图1、图3),所以因构成弹性支承装置6的压缩螺旋弹簧61的作用,通过更强的力将外槽3向中心方向推回去。此时,压缩螺旋弹簧61以预先给予了加压Fp的状态被作为位移限制装置的限制绳62限制。因此在即使只产生一点位移的情况下解除基于限制绳62的限制,加上上升加压Fp的量而作用于外槽3。即,在外槽3大幅度地振动并位移了间隙E以上的情况下,由于包括加压Fp而急剧地作用大的弹簧力,弹簧常数k看上去变大。即,弹簧特性直线La在振幅e为间隙E以上的区域中,向倾斜更大的弹簧特性直线Lb转变。However, as described above, in the present embodiment, since there is a gap E between the outer tub 3 and the main body 2 and the second elastic supporting device 6 is provided (refer to FIGS. 1 and 3), the compression is constituted by the elastic supporting device 6. The action of the coil spring 61 pushes the outer groove 3 back toward the center by a stronger force. At this time, the compression coil spring 61 is restricted by the restriction cord 62 as the displacement limiting means in a state in which the pressure Fp is given in advance. Therefore, even if only a slight displacement occurs, the restriction by the restriction rope 62 is released, and the amount of the upward pressure Fp is applied to the outer tank 3. In other words, when the outer tank 3 is largely vibrated and displaced by the gap E or more, the spring constant k acts to increase as the spring force is greatly increased by the pressurization Fp. In other words, the spring characteristic straight line La changes to the spring characteristic line Lb having a larger inclination in a region where the amplitude e is equal to or larger than the gap E.
由此,变为与惯性直线L4和弹簧特性直线Lb的交点P4对应的振幅e和振动力F,振幅e急剧变小。这表示出外槽3的低次固有振动数通过第二弹性支承装置6进行变化,由于产生与角频率ω的偏移而减少振动。Thereby, the amplitude e and the vibration force F corresponding to the intersection P4 of the inertia line L4 and the spring characteristic line Lb become abruptly small. This indicates that the number of low-order natural vibrations of the outer tank 3 is changed by the second elastic supporting device 6, and the vibration is reduced by the offset from the angular frequency ω.
由于振幅e变得比间隙E更小而外槽3的低次固有振动数再次返回原状,此时角频率ω变得比低次固有振动数更大,不会再次产生共振而能维持振幅e小的状态。即,即使角频率ω增大,移至如惯性直线L5、L6那样,也如和弹簧 特性直线La的交点P5、P6所示,振幅e不会超过间隙E,能维持小的水平。Since the amplitude e becomes smaller than the gap E and the number of low-order natural vibrations of the outer groove 3 returns to the original state again, the angular frequency ω becomes larger than the number of low-order natural vibrations, and the resonance is not generated again, and the amplitude e can be maintained. Small state. That is, even if the angular frequency ω is increased, moving to the inertia lines L5, L6, as with the spring As shown by the intersections P5 and P6 of the characteristic line La, the amplitude e does not exceed the gap E, and can be maintained at a small level.
此外,弹簧特性直线Lb不需要一定通过原点,弹簧常数k看上去是急剧增大的关系即可。即,只要将加压Fp设定地足够大,就也可以适当地变更给予加压时的压缩量ΔL和间隙E(参照图3)的大小。Further, the spring characteristic straight line Lb does not have to pass through the origin, and the spring constant k seems to be a sharply increasing relationship. In other words, if the pressure Fp is set sufficiently large, the amount of compression ΔL and the gap E (see FIG. 3) at the time of pressurization can be appropriately changed.
如上所述,由于在外槽3设置有具备压缩螺旋弹簧61的第二弹性支承装置6,因而在使洗涤脱水槽4旋转增速到规定的运转速度期间,角频率ω、即旋转速度接近外槽3的低次固有振动数,在振幅e超过间隙E变大的情况下,第二弹性支承装置6与主体2的内表面21a抵接。构成第二弹性支承装置6的压缩螺旋弹簧61由于以预先被给予了加压的状态向伸长方向的位移是受限制的,因而在产生了向压缩方向位移的情况下通过加压Fp发生作用从而使低次固有振动数进行大的变化,由此可以减少振动。进而,在振幅e变得比间隙E更小的情况下低次固有振动数返回原状,但是洗涤脱水槽4的旋转速度会变大,由于成为已经从低次固有振动数分离的状态,所以能抑制振动的增大。As described above, since the second elastic supporting device 6 including the compression coil spring 61 is provided in the outer tub 3, the angular frequency ω, that is, the rotational speed is close to the outer groove while the washing and dewatering tank 4 is rotationally increased to a predetermined operating speed. When the amplitude e exceeds the gap E, the second elastic support device 6 abuts against the inner surface 21a of the main body 2 when the amplitude e exceeds the gap E. The compression coil spring 61 constituting the second elastic supporting device 6 is restricted in displacement in the elongation direction by being pressurized in advance, and thus acts by pressurizing Fp in the case where displacement in the compression direction occurs. Thereby, the number of low-order natural vibrations is largely changed, whereby vibration can be reduced. Further, when the amplitude e is smaller than the gap E, the number of the low-order natural vibrations returns to the original state, but the rotational speed of the washing and dewatering tank 4 is increased, and the state of the low-order natural vibration is separated. Suppresses the increase in vibration.
因此,能将振动以及噪声抑制得较小,能改善洗衣机1的设置场所周边的环境。进而,即使主体2和外槽3的间隙E缩小,由于能抑制因振动而导致的这些激烈的碰撞并损伤,因而能相对于外槽3使本体2缩小使洗衣机1整体小型化。此外,将主体2的尺寸保持原样,在将外槽3增大的情况下,不需要改变洗衣机1整体的尺寸就可以使洗涤容量增大。Therefore, it is possible to suppress vibration and noise to a small extent, and it is possible to improve the environment around the installation place of the washing machine 1. Further, even if the gap E between the main body 2 and the outer tub 3 is reduced, it is possible to suppress these severe collisions and damage due to vibration, and thus the main body 2 can be reduced with respect to the outer tub 3 to reduce the size of the entire washing machine 1. Further, the size of the main body 2 is kept as it is, and in the case where the outer tub 3 is increased, the washing capacity can be increased without changing the size of the entire washing machine 1.
然后,将构成第二弹性支承装置6的压缩螺旋弹簧61安装于外槽3侧,伴随着外槽3的位移在其和压缩螺旋弹簧61之间抵接,使反复分离的对象侧作为主体2。由于主体2的侧板21由金属形成,所以对于压缩螺旋弹簧61的抵接/分离具有足够的强度,损伤的可能较小。进而,由于使压缩螺旋弹簧61的前端(另一端)61b和主体2的侧板21大致平行地相对,所以还能防止抵接时的一侧部分接触而可以防止局部磨耗。而且,在构成主体2的侧板21的内表面21a,减少用于进行加强的金属板、压缩螺旋弹簧61抵接时的冲击并且适合设置用于实现噪声的减少的弹性片。Then, the compression coil spring 61 constituting the second elastic supporting device 6 is attached to the outer groove 3 side, and the displacement of the outer groove 3 abuts between the compression coil spring 61 and the object side which is repeatedly separated as the main body 2 . Since the side plate 21 of the main body 2 is formed of metal, there is sufficient strength for the abutment/separation of the compression coil spring 61, and the possibility of damage is small. Further, since the front end (the other end) 61b of the compression coil spring 61 and the side plate 21 of the main body 2 are opposed to each other substantially in parallel, it is possible to prevent the one side portion at the time of contact from coming into contact, and it is possible to prevent local wear. Further, in the inner surface 21a of the side plate 21 constituting the main body 2, the impact of the metal plate for reinforcement and the compression coil spring 61 abutting is reduced, and an elastic piece for realizing reduction of noise is suitably provided.
另一方面,虽然外槽3由树脂形成,表面的强度比较低,但是因为不会反复与压缩螺旋弹簧61的抵接、分离,所以能抑制表面的磨耗,即使长时间的使用也能减少损伤的可能。On the other hand, although the outer tank 3 is formed of a resin and the strength of the surface is relatively low, since the contact and separation with the compression coil spring 61 are not repeated, the abrasion of the surface can be suppressed, and the damage can be reduced even after long-term use. Possible.
进而,如上所述,由于压缩螺旋弹簧61通过基端构件63安装于外槽3的外表面32a,所以外槽3的外表面32a不需要一定为圆周面,可以是设置筋、配 管、布线的安装部等的形状,也可以提高设计自由度。Further, as described above, since the compression coil spring 61 is attached to the outer surface 32a of the outer groove 3 through the proximal end member 63, the outer surface 32a of the outer groove 3 does not need to be a circumferential surface, and may be provided with a rib. The shape of the pipe or the mounting portion of the wiring can also increase the degree of design freedom.
图6是表示图1等所示的第一实施方式的洗衣机1(1A)的第一变形例的纵剖图。因为除了后述的结构之外都与图1~图5所示的洗衣机1A相同,所以在相同的部分注上相同的附图标记并省略说明。Fig. 6 is a vertical cross-sectional view showing a first modification of the washing machine 1 (1A) of the first embodiment shown in Fig. 1 and the like. The same components as those of the washing machine 1A shown in FIG. 1 to FIG. 5 are denoted by the same reference numerals, and their description is omitted.
图6所示的洗衣机1B是在图1所示的洗衣机1A的结构上,进而附加四个第二弹性支承装置6~6。具体地说,该洗衣机1B在图1所示洗衣机1A所具备的第二弹性支承装置6~6的正下方,在距离外槽3的下方约1/3左右的高度位置,具备第二弹性支承装置6。The washing machine 1B shown in Fig. 6 is a structure of the washing machine 1A shown in Fig. 1, and further four fourth elastic supporting means 6 to 6 are attached. Specifically, the washing machine 1B has a second elastic support at a height position about 1/3 of a distance from the outer groove 3 directly below the second elastic supporting devices 6 to 6 provided in the washing machine 1A shown in Fig. 1 . Device 6.
这样由于洗衣机1B在上下方向(Z方向)上以二层的方式配置第二弹性支承装置6,因而即使在外槽3在x轴、y轴附近摆动的情况下上下的第二弹性支承装置6也与主体2抵接,能抑制外槽3的倾斜。因此,不仅能抑制外槽3绕旋转轴Ra回旋的方式的振动,也能抑制绕x轴、y轴摆动的纵摇模式的振动。此外,如果允许重量的增加的话,也可以是三层以上地设置第二弹性支承装置6的结构。In this way, since the second elastic supporting device 6 is disposed in a two-layer manner in the vertical direction (Z direction) of the washing machine 1B, even when the outer groove 3 is swung in the vicinity of the x-axis and the y-axis, the upper and lower second elastic supporting devices 6 are also Abutment with the main body 2 can suppress the inclination of the outer tub 3. Therefore, it is possible to suppress not only the vibration of the outer groove 3 around the rotation axis Ra but also the vibration of the pitch mode about the x-axis and the y-axis. Further, if the increase in weight is allowed, the structure of the second elastic supporting device 6 may be provided in three or more layers.
图7(a)为表示图1等示出的第一实施方式的洗衣机1(1A)的第二变形例的图。因为除了后述的结构之外都与图1~图5所示的洗衣机1A相同,所以在相同的部分中注上相同的附图标记并省略说明。Fig. 7 (a) is a view showing a second modification of the washing machine 1 (1A) of the first embodiment shown in Fig. 1 and the like. The same components as those of the washing machine 1A shown in FIGS. 1 to 5 are denoted by the same reference numerals, and the description thereof will be omitted.
图7(a)所示的洗衣机1C在主体2的内侧设置作为被抵接部的被抵接板71这一点上与图1所示的洗衣机1A不同。图7(b)为用于说明该被抵接板71的形状的立体图。被抵接板71配置为与构成主体2的侧板21的内表面21a抵接的俯视为大致圆形、用树脂或者钢铁制的薄板形成的带状部材。该被抵接板71和构成第二弹性支承装置6的压缩螺旋弹簧61,配置成可以通过前端构件64(参照图3)相互抵接的位置关系。进而,被抵接板71具备在上下方向上比压缩螺旋弹簧61的直径稍大的宽度尺寸,有效地构成为可以与第二弹性支承装置6抵接。此外,被抵接板71不需要由一个构件构成,也可以构成为通过连接多个构件而成为俯视为大致圆形。The washing machine 1C shown in Fig. 7(a) is different from the washing machine 1A shown in Fig. 1 in that a contact plate 71 as a contact portion is provided inside the main body 2. Fig. 7 (b) is a perspective view for explaining the shape of the abutted plate 71. The abutting plate 71 is disposed in a strip shape which is formed in a substantially circular shape in a plan view and which is in contact with the inner surface 21a of the side plate 21 of the main body 2, and is formed of a resin or a steel plate. The abutted plate 71 and the compression coil spring 61 constituting the second elastic supporting device 6 are disposed in a positional relationship in which the distal end members 64 (see FIG. 3) abut each other. Further, the contacted plate 71 has a width dimension slightly larger than the diameter of the compression coil spring 61 in the vertical direction, and is configured to be able to abut against the second elastic support device 6. Further, the abutted plate 71 does not need to be constituted by one member, and may be configured to have a substantially circular shape in plan view by connecting a plurality of members.
如果是上述那样的结构,则因为第二弹性支承装置6通过被抵接板71与主体2抵接,所以能缓和抵接时的对主体2的冲击,能抑制主体2的损伤。此外,通过第二弹性支承装置6与曲面抵接,即使在外槽3绕旋转轴Ra摆动的情况下,因为抵接状态不会不稳定而能保持均匀的接触,所以也可以更适当地抑制振动。进而,通过适当地变更被抵接板71的尺寸和材质,也能变更主体2和第二弹性 支承装置6的摩擦力,因此还可以进一步提高振动抑制效果。In the above-described configuration, the second elastic supporting device 6 is in contact with the main body 2 by the abutting plate 71, so that the impact on the main body 2 at the time of abutment can be alleviated, and the damage of the main body 2 can be suppressed. Further, when the second elastic support device 6 abuts against the curved surface, even when the outer groove 3 is swung around the rotation axis Ra, since the contact state is not unstable and uniform contact can be maintained, the vibration can be more appropriately suppressed. . Further, the main body 2 and the second elasticity can be changed by appropriately changing the size and material of the abutment plate 71. The frictional force of the support device 6 can further improve the vibration suppression effect.
(第二实施方式)(Second embodiment)
图8(a)与上述的第一实施方式中的图2对应,为表示本发明的第二实施方式的洗衣机201(201A)的横剖图。因为除了后述的结构之外都与第一实施方式(图1~图5)所示的洗衣机1相同,所以在相同的部分注上相同的附图标记并省略说明。Fig. 8(a) corresponds to Fig. 2 in the first embodiment described above, and is a cross-sectional view showing the washing machine 201 (201A) according to the second embodiment of the present invention. The same components as those of the first embodiment (FIGS. 1 to 5) are denoted by the same reference numerals, and the description thereof is omitted.
图8(a)所示的洗衣机201的第二弹性支承装置6的配置、以及外槽3的安装构造与第一实施方式的洗衣机1(参照图2)不同。The arrangement of the second elastic supporting device 6 of the washing machine 201 shown in Fig. 8(a) and the mounting structure of the outer tub 3 are different from those of the washing machine 1 (see Fig. 2) of the first embodiment.
具体地说,x方向弹性支承装置6x和y方向弹性支承装置6y,与构成这些的作为弹性体的压缩螺旋弹簧61、61一起,各一个地成组地与主体2中的内部空间2a的角落部2a1接近,并且以旋转轴Ra为中心设置在双方的组为轴对称的位置上。Specifically, the x-direction elastic supporting device 6x and the y-direction elastic supporting device 6y, together with the compression coil springs 61, 61 constituting these as the elastic bodies, are grouped one by one with the corner of the internal space 2a in the main body 2 The portion 2a1 is close to each other, and is disposed at a position where both sets are axisymmetric about the rotation axis Ra.
图8(b)为图8(a)所示的洗衣机201的主要部位的放大图。如图8(b)所示,构成各个组的x方向弹性支承装置6x和y方向弹性支承装置6y安装于设置在外槽3的外表面32a的共用台座236上。台座236具备与x方向正交的安装面、以及与y方向正交的安装面,分别安装x方向弹性支承装置6x或者y方向弹性支承装置6y。因此,适当地设定各个第二弹性支承装置6x、6y的位置关系,能减少部件件数。此外,该实施方式中的第二弹性支承装置6因为适当地进行对台座236的安装,所以具备安装面为平坦的板状的基端构件263来代替图3所示的基端构件63。Fig. 8 (b) is an enlarged view of a main part of the washing machine 201 shown in Fig. 8 (a). As shown in Fig. 8(b), the x-direction elastic supporting device 6x and the y-direction elastic supporting device 6y constituting each group are attached to a common pedestal 236 provided on the outer surface 32a of the outer tub 3. The pedestal 236 includes a mounting surface orthogonal to the x direction and a mounting surface orthogonal to the y direction, and the x-direction elastic supporting device 6x or the y-direction elastic supporting device 6y is attached. Therefore, the positional relationship of each of the second elastic supporting devices 6x and 6y is appropriately set, and the number of components can be reduced. Further, since the second elastic supporting device 6 in this embodiment is appropriately attached to the pedestal 236, a plate-like base end member 263 having a flat mounting surface is provided instead of the base end member 63 shown in FIG.
此外,各个第二弹性支承装置6和主体2的内表面21a分别与第一实施方式相同,隔着间隙E对置。Further, the respective second elastic supporting means 6 and the inner surface 21a of the main body 2 are respectively opposed to the first embodiment, and opposed to each other via the gap E.
因此,本实施方式具有与上述第一实施方式相同的效果,并且通过将第二弹性支承装置6与容易成为主体2内的无用空间的角落部2a1接近配置,从而能有效地活用空间以实现洗衣机201整体的进一步小型化。Therefore, the present embodiment has the same effects as those of the above-described first embodiment, and the second elastic supporting device 6 is disposed close to the corner portion 2a1 which is easy to become a useless space in the main body 2, thereby effectively utilizing the space to realize the washing machine. Further miniaturization of 201 as a whole.
进而,即使在不产生外槽3绕旋转轴Ra回旋的振动的情况下,换句话说即使在外槽3没有进行x、y方向的任一位移的情况下,在外槽3绕旋转轴Ra摆动的情况下也能使第二弹性支承装置6的前端构件64与主体2抵接。因此,由于电机34的旋转不均或转矩脉动等原因,即使在绕旋转轴Ra附近摆动方式的振动的情况下,也能适当地抑制该振动。Further, even in the case where the vibration of the outer groove 3 around the rotation axis Ra is not generated, in other words, even if the outer groove 3 does not perform any displacement in the x and y directions, the outer groove 3 is swung around the rotation axis Ra. In this case, the front end member 64 of the second elastic supporting device 6 can also be brought into contact with the main body 2. Therefore, even if the vibration of the swing mode is around the rotation axis Ra due to the uneven rotation of the motor 34 or the torque ripple or the like, the vibration can be appropriately suppressed.
图9为表示图8所示的第二实施方式的洗衣机201(201A)的变形例的图。 因为除了后述的结构之外都与图8所示的洗衣机201A相同,所以在相同的部分注上相同的附图标记并省略说明。FIG. 9 is a view showing a modification of the washing machine 201 (201A) of the second embodiment shown in FIG. 8. The same components as those of the washing machine 201A shown in FIG. 8 are denoted by the same reference numerals, and the description thereof will be omitted.
图9所示的洗衣机201B,在主体2的内侧具备被抵接块271这一点上与图8所示的洗衣机201A不同。被抵接块271分别设置于隔着四个第二弹性支承装置6~6和间隙E(参照图8)对置的位置。各个被抵接块271的安装面271a形成为平面状,将该安装面271a以与构成主体2的侧板21的内表面21a抵接的状态固定,并且在与第二弹性支承装置6~6对置的一侧形成作为被抵接部的被抵接面271b。被抵接面271b制成为其中央附近比第二弹性支承装置6的前端构件64(参照图3)稍微宽度大的平面,由此随着向端部方向行进而使向主体2的内侧凸出的曲面顺利地连续形成。The washing machine 201B shown in FIG. 9 is different from the washing machine 201A shown in FIG. 8 in that the main body 2 is provided with the abutting block 271. The abutted blocks 271 are respectively disposed at positions opposed to the gap E (see FIG. 8) via the four second elastic supporting devices 6 to 6. The mounting surface 271a of each of the abutting blocks 271 is formed in a planar shape, and the mounting surface 271a is fixed in a state of abutting against the inner surface 21a of the side plate 21 constituting the main body 2, and is in contact with the second elastic supporting means 6 to 6 The opposite side forms a contacted surface 271b as a contacted portion. The abutting surface 271b is formed as a plane having a slightly larger width than the front end member 64 (refer to FIG. 3) of the second elastic supporting device 6 in the vicinity of the center thereof, and thus protrudes toward the inner side of the main body 2 as it travels in the end direction. The curved surface is smoothly formed continuously.
在如上述构成的情况下,能适当地实现构成主体2的侧板2的保护,并且即使在外槽3绕旋转轴Ra摆动的情况下,因为在被抵接面271b包括曲面,所以能使与第二弹性支承装置6的接触状态均匀化,能更合适地得到振动抑制效果。In the case of the above configuration, the protection of the side plate 2 constituting the main body 2 can be appropriately realized, and even in the case where the outer groove 3 is swung around the rotation axis Ra, since the abutting surface 271b includes a curved surface, it is possible to The contact state of the second elastic supporting device 6 is made uniform, and the vibration suppressing effect can be more appropriately obtained.
(第三实施方式)(Third embodiment)
图10(a)与上述第一实施方式中的图2对应,是表示本发明的第三实施方式的洗衣机301(301A)的横剖图。因为除了后述的结构之外都与第三实施方式(图1~图5)所示的洗衣机1相同,所以在相同的部分注上相同的附图标记并省略说明。Fig. 10 (a) corresponds to Fig. 2 in the first embodiment, and is a cross-sectional view showing a washing machine 301 (301A) according to a third embodiment of the present invention. The same components as those of the first embodiment (FIGS. 1 to 5) are denoted by the same reference numerals, and the description thereof is omitted.
图10(a)所示的洗衣机301在第二弹性支承装置306的结构、以及设置与该第二弹性支承装置306相对的被抵接块371这一点上与第一实施方式的洗衣机1(图2参照)不同。第二弹性支承装置306与第一实施方式中的第二弹性支承装置6(参照图2)结构不同,但相对于外槽3配置于相同的位置。The washing machine 301 shown in Fig. 10(a) is in the same manner as the washing machine 1 of the first embodiment in the configuration of the second elastic supporting device 306 and the abutting block 371 provided opposite to the second elastic supporting device 306. 2 reference) is different. The second elastic supporting device 306 is different in structure from the second elastic supporting device 6 (see FIG. 2) in the first embodiment, but is disposed at the same position with respect to the outer groove 3.
图11为表示第二弹性支承装置306的结构的剖视图。该实施方式中的第二弹性支承装置306构成为图11(a)所示的弹性单元306A。弹性单元306A由一端打开且在另一端设置有开口362a的壳体362、朝向主体2的内表面21a(参照图10)形成为凸状并作为从壳体362的开口362a开始使前端363b凸出的抵接部的轴体363、作为设置于壳体362内的弹性体的压缩螺旋弹簧361A、以及密封壳体362的另一端的基端构件364构成。FIG. 11 is a cross-sectional view showing the structure of the second elastic supporting device 306. The second elastic supporting device 306 in this embodiment is configured as an elastic unit 306A shown in Fig. 11(a). The elastic unit 306A is formed of a housing 362 that is opened at one end and provided with an opening 362a at the other end, and is formed in a convex shape toward the inner surface 21a (refer to FIG. 10) of the main body 2 and protrudes from the opening 362a of the housing 362 to protrude the front end 363b. The shaft body 363 of the abutting portion is composed of a compression coil spring 361A which is an elastic body provided in the casing 362, and a base end member 364 which seals the other end of the casing 362.
上述轴体363具备比开口362a稍小的剖面形状,并且在基端侧具备比开口362a大的凸缘部363a。轴体363的前端363b形成为半球面状,能与被抵接块 371(参照图10)顺利地抵接。The shaft body 363 has a cross-sectional shape slightly smaller than the opening 362a, and has a flange portion 363a larger than the opening 362a on the proximal end side. The front end 363b of the shaft body 363 is formed in a hemispherical shape and can be abutted with the block 371 (refer to FIG. 10) smoothly abuts.
压缩螺旋弹簧361A第一实施方式相同以与被给予了加压Fp(参照图3)的状态被收容,并由基端构件364密封。进而,弹性单元306A通过将该基端构件364安装于外槽3的外表面32a而固定在外槽3上。通过这样,压缩螺旋弹簧361A的一端通过基端构件364与外槽3的外表面32a连接,并在另一端上设置上述轴体363。The first embodiment of the compression coil spring 361A is housed in the same state as the pressurized Fp (see FIG. 3), and is sealed by the proximal end member 364. Further, the elastic unit 306A is fixed to the outer tub 3 by attaching the base end member 364 to the outer surface 32a of the outer tub 3. Thus, one end of the compression coil spring 361A is connected to the outer surface 32a of the outer tub 3 through the base end member 364, and the above-mentioned shaft body 363 is provided on the other end.
轴体363由压缩螺旋弹簧361A向前端363b凸出的方向施力,通过凸缘部363a被壳体362的端部卡住从而禁止更进一步的凸出。即,壳体362以向压缩螺旋弹簧361A给予了加压的状态为基准,作为允许该压缩螺旋弹簧361A前端向压缩方向的位移、限制向伸长方向的位移的位移限制装置发挥功能。The shaft body 363 is biased by the compression coil spring 361A in a direction in which the front end 363b protrudes, and is caught by the end portion of the casing 362 by the flange portion 363a, thereby prohibiting further protrusion. In other words, the housing 362 functions as a displacement restricting means that allows displacement of the distal end of the compression coil spring 361A in the compression direction and restricts displacement in the extension direction, based on the state in which the compression coil spring 361A is pressurized.
根据该状态,如图11(b)所示,在将轴体363的前端363b向轴向推入的情况下,解除由壳体362带来的限制,对轴体363作用加压FP以上的弹簧力。According to this state, when the front end 363b of the shaft body 363 is pushed in the axial direction as shown in FIG. 11(b), the restriction by the casing 362 is released, and the shaft body 363 is pressurized by FP or more. Spring force.
此外,第二弹性支承装置306除了构成为具备图11(a)、(b)所示的压缩螺旋弹簧361A的弹性单元306A,也可以构成为具备图11(c)、(d)所示的弹性构件361B的弹性单元306B。弹性构件361B与压缩螺旋弹簧361A相同,具有由于压缩而产生反作用力的性质的部件即可,也可以是橡胶或发泡海绵等。进而,也可以将进行金属或树脂的切削加工时产生的切削屑作为弹性构件361B使用。Further, the second elastic supporting device 306 may be configured to include the elastic unit 306A having the compression coil spring 361A shown in FIGS. 11(a) and 11(b), and may be configured as shown in FIGS. 11(c) and 11(d). The elastic unit 306B of the elastic member 361B. Similarly to the compression coil spring 361A, the elastic member 361B may have a property of generating a reaction force due to compression, and may be a rubber or a foamed sponge. Further, the chips generated when the metal or resin is cut may be used as the elastic member 361B.
返回图10(a),如上所述由弹性单元306A(参照图11)构成的第二弹性支承装置306设置于夹着外槽3在x方向分离的两处,进而设置于夹着外槽3在y方向分离的两处。即,第二弹性支承装置306配置在俯视时以旋转轴Ra为中心构成十字型的位置上。进而,在与第二弹性支承装置306相对的位置上分别设置被抵接块371,固定在构成本体2的侧板21的内表面21a上。Returning to Fig. 10 (a), the second elastic supporting means 306 constituted by the elastic unit 306A (refer to Fig. 11) as described above is disposed at two places separated in the x direction by the outer groove 3, and is further disposed to sandwich the outer groove 3. Two places separated in the y direction. In other words, the second elastic supporting device 306 is disposed at a position that forms a cross shape around the rotation axis Ra in plan view. Further, the abutting block 371 is provided at a position opposed to the second elastic supporting device 306, and is fixed to the inner surface 21a of the side plate 21 constituting the body 2.
图10(b)为表示被抵接块371和弹性单元306A的位置关系的图。被抵接块371具备作为被抵接部的被抵接面371a,该被抵接面371a由以经过构成弹性单元306A的轴体363的前端363b并与旋转轴Ra平行的轴心为中心的俯视为圆弧状的曲面构成。在洗衣机301停止的稳定状态下,无论在被抵接面371a的任何位置上,距离轴体363的前端363b的距离d都大致相等。距离d相当于上述的第一实施方式中的间隙E(参照图3),通过使外槽3位移了该间隙E的量,从而弹性单元306A会抵接于被抵接面371a。进而,由于被抵接面371a构成为以轴体363的前端363b为中心的曲面,所以如图10(c)所示,在轴体363的 前端363b将原本的位置作为基准回旋的方式下进行位移的情况下,能使两者顺利地抵接。Fig. 10 (b) is a view showing the positional relationship between the abutted block 371 and the elastic unit 306A. The abutting block 371 is provided with a contact surface 371a as a contact portion that is centered on an axis that passes through the front end 363b of the shaft body 363 that constitutes the elastic unit 306A and is parallel to the rotation axis Ra. It is composed of a curved surface in a plan view. In a steady state in which the washing machine 301 is stopped, the distance d from the front end 363b of the shaft body 363 is substantially equal regardless of the position of the abutting surface 371a. The distance d corresponds to the gap E (see FIG. 3) in the above-described first embodiment, and by displacing the outer groove 3 by the amount of the gap E, the elastic unit 306A abuts against the abutted surface 371a. Further, since the contact surface 371a is formed as a curved surface centering on the distal end 363b of the shaft 363, as shown in FIG. 10(c), the shaft 363 is When the distal end 363b is displaced in a manner in which the original position is rotated as a reference, the both can be smoothly brought into contact with each other.
因此,在本实施方式中,具有与上述的第一实施方式相同的效果,并且在产生了外槽3的回旋振动的情况下,使构成弹性单元306A的轴体363的前端363b和作为被抵接部的被抵接面371a顺利地抵接,能适当地减少振动。Therefore, in the present embodiment, the same effect as the above-described first embodiment is obtained, and in the case where the whirling vibration of the outer tub 3 is generated, the front end 363b of the shaft body 363 constituting the elastic unit 306A is placed as a result. The abutted surface 371a of the joint portion is smoothly abutted, and vibration can be appropriately reduced.
图12为表示图10所示的第三实施方式的洗衣机301(301A)的变形例的图。因为除了后述的结构之外都与图10所示的洗衣机301A相同,所以在相同的部分注上相同的附图标记并省略说明。Fig. 12 is a view showing a modification of the washing machine 301 (301A) of the third embodiment shown in Fig. 10 . The same components as those of the washing machine 301A shown in FIG. 10 are denoted by the same reference numerals, and their description will be omitted.
图12所示的洗衣机301B具备作为第二弹性支承装置306的弹性单元306A(参照图11),并且构成为与第二实施方式的洗衣机201A、201B(参照图8、9)相同。具体地说,洗衣机301Bは,沿着x方向配置的弹性单元306x和y方向弹性单元306y各一个地成组地配置于主体2的内部空间2a的角落部2a1。此外,这些弹性单元306x和y方向弹性单元306y通过被安装于设置在外槽3的外表面32a上的共用台座236上,从而配置到适当的位置。进而,被抵接块371分别设置在隔着相当于第一实施方式中的间隙E(参照图3)的间隙d(参照图10)与这些弹性单元306x、306y相对的位置上。The washing machine 301B shown in Fig. 12 includes an elastic unit 306A (see Fig. 11) as the second elastic supporting device 306, and is configured similarly to the washing machines 201A and 201B (see Figs. 8 and 9) of the second embodiment. Specifically, in the washing machine 301B, the elastic unit 306x and the y-direction elastic unit 306y arranged along the x direction are arranged in groups at the corner portion 2a1 of the internal space 2a of the main body 2, respectively. Further, these elastic unit 306x and y-direction elastic unit 306y are disposed in an appropriate position by being mounted on a common pedestal 236 provided on the outer surface 32a of the outer tub 3. Further, the abutted blocks 371 are respectively disposed at positions facing the elastic units 306x and 306y via a gap d (see FIG. 10) corresponding to the gap E (see FIG. 3) in the first embodiment.
在这样构成的情况下,能得到上述的效果,并且与第二实施方式相同,即使在产生了绕旋转轴Ra摆动的方式的振动的情况下,也能适当地抑制该振动。此外,因为第二弹性支承装置306构成为弹性单元306A(参照图11),所以元件的操作变得容易,也能实现组装工时的减少和小型化。In the case of such a configuration, the above-described effects can be obtained, and similarly to the second embodiment, even when vibration of a mode that oscillates around the rotation axis Ra occurs, the vibration can be appropriately suppressed. Further, since the second elastic supporting device 306 is configured as the elastic unit 306A (refer to FIG. 11), the operation of the components becomes easy, and the assembly man-hour can be reduced and miniaturized.
(第四实施方式)(Fourth embodiment)
图13与上述的第一实施方式对应,是表示本发明的第四实施方式的洗衣机401(401A)的横剖图。因为除了后述的结构之外都与第二实施方式(图8参照)所示的洗衣机201相同,所以在相同的部分注上相同的附图标记并省略说明。Fig. 13 is a cross-sectional view showing a washing machine 401 (401A) according to a fourth embodiment of the present invention, corresponding to the first embodiment described above. The same components as those of the washing machine 201 shown in the second embodiment (refer to FIG. 8) are denoted by the same reference numerals, and the description thereof will be omitted.
图13(a)所示的洗衣机401在作为第二弹性支承装置的x方向弹性支承装置6x和y方向弹性支承装置6y的前端设置有作为抵接部的曲面板481,并且在与该曲面板481相对的被抵接块471设置在主体2这一点上与第二实施方式的洗衣机201(参照图8)不同。The washing machine 401 shown in Fig. 13 (a) is provided with a curved panel 481 as an abutting portion at the front end of the x-direction elastic supporting device 6x and the y-direction elastic supporting device 6y as the second elastic supporting means, and in the curved panel The 481 opposing abutment block 471 is different from the washing machine 201 (see FIG. 8) of the second embodiment in that it is provided on the main body 2.
曲面板481俯视为圆弧状,是由树脂或金属制的薄板形成的带状构件。通过该曲面板481,使一个x方向弹性支承装置6x的前端和与此接近的一个y方向弹性支承装置6y的前端连接。即,作为构成这些弹性支承装置6x、6y的弹 性体的压缩螺旋弹簧61、61分别使一端61a与外槽3的外表面32a连接,并且通过曲面板481将另一端61b之间连接。此外,以与z轴平行的轴心Cc(参照图13(b)、(c))为中心,设定上述曲面板481所成的圆弧的位置,其中轴心Cc通过经过x方向弹性支承装置6x的轴心的直线和经过y方向弹性支承装置6x的轴心的直线的交点。该曲面板481也同样地设置于配置在以旋转轴Ra为中心的对称的位置上的、其它组的x方向弹性支承装置6x和y方向弹性支承装置6y的前端。The curved panel 481 has a circular arc shape in plan view and is a strip-shaped member formed of a resin or a metal thin plate. The front end of one of the x-direction elastic supporting means 6x is connected to the front end of one of the y-direction elastic supporting means 6y which is adjacent thereto by the curved panel 481. That is, as a bullet constituting these elastic supporting means 6x, 6y The compression coil springs 61, 61 of the body respectively connect the one end 61a to the outer surface 32a of the outer groove 3, and connect the other ends 61b through the curved panel 481. Further, the position of the arc formed by the curved panel 481 is set centering on the axis Cc (see FIGS. 13(b) and (c)) parallel to the z-axis, wherein the axis Cc is elastically supported by the x-direction. The intersection of the straight line of the axis of the device 6x and the straight line passing through the axis of the elastic support device 6x in the y direction. Similarly, the curved panel 481 is provided at the front end of the other group of the x-direction elastic supporting device 6x and the y-direction elastic supporting device 6y disposed at a position symmetrical about the rotation axis Ra.
被抵接块471构成为与上述曲面板481对置的块状,设置于主体2的内部空间2a的角落部2a1。另外,被抵接部471也配置于以旋转轴Ra为中心的对称的两处。被抵接块471具备形成为圆弧状的凹曲面的、与上述的曲面板481对置的作为被抵接部的被抵接面471a。被抵接面471和曲面板481配置为在洗衣机401停止的稳定状态下,以相同的轴心Cc为中心。因此,在曲面板481和被抵接面471a对置的范围内,两者的间隙E(参照图3)无论在任何方向上都大致均匀。而且,曲面板481以及被抵接块471的被抵接面471a所成的圆弧的角度设定为120°附近,在该范围下两者能抵接。The abutted block 471 is configured in a block shape facing the curved panel 481, and is provided in the corner portion 2a1 of the internal space 2a of the main body 2. Further, the abutted portion 471 is also disposed at two locations symmetric about the rotation axis Ra. The abutted block 471 includes a contact surface 471a as a contacted portion that faces the above-described curved panel 481 and has a concave curved surface formed in an arc shape. The abutted surface 471 and the curved panel 481 are disposed such that the same axis Cc is centered in a steady state in which the washing machine 401 is stopped. Therefore, in the range in which the curved panel 481 and the abutted surface 471a face each other, the gap E (see FIG. 3) is substantially uniform in any direction. Further, the angle of the arc formed by the curved panel 481 and the abutted surface 471a of the abutting block 471 is set to be around 120°, and both of them can abut in this range.
通过构成为上述那样,即使在如图13(b)所示在外槽3向图中上方向位移的情况下,即使在如图13(c)所示在外槽3向图中左上方向位移的情况下,也是只要是相同的位移量,曲面板481就能与被抵接块471抵接。因此,在外槽3回旋振动期间,能通过曲面板481适当地使压缩螺旋弹簧61发生作用。As described above, even when the outer groove 3 is displaced upward in the drawing as shown in FIG. 13(b), even if the outer groove 3 is displaced in the upper left direction in the drawing as shown in FIG. 13(c). Next, as long as the same displacement amount, the curved panel 481 can abut against the abutted block 471. Therefore, during the swirling vibration of the outer tub 3, the compression coil spring 61 can be appropriately acted upon by the curved panel 481.
因此,在本实施方式中,具有与上述的第一实施方式相同的效果,并且在产生了外槽3的回旋振动的情况下,通过使设置于主体2的被抵接块471与设置在第二弹性支承装置6上的曲面板481抵接,从而能适当地使压缩螺旋弹簧61发生作用,能适当地使振动减少。进而,因为方向不同的x方向弹性支承装置6x和y方向弹性支承装置6y通过曲面板481连接,所以根据外槽3的位移的方向的变化能使作用的第二弹性支承装置6顺利地切换。因此,可以更适当地抑制振动。Therefore, in the present embodiment, the same effect as the above-described first embodiment is obtained, and in the case where the whirling vibration of the outer tub 3 is generated, the abutted block 471 provided in the main body 2 is placed in the first The curved panel 481 on the two elastic supporting devices 6 abuts, so that the compression coil spring 61 can be appropriately operated, and the vibration can be appropriately reduced. Further, since the x-direction elastic supporting device 6x and the y-direction elastic supporting device 6y having different directions are connected by the curved plate 481, the second elastic supporting device 6 that is acting can be smoothly switched according to the change in the direction of the displacement of the outer groove 3. Therefore, the vibration can be more appropriately suppressed.
图14为表示图13所示的第四实施方式的洗衣机401(401A)的第一变形例的图。因为除了后述的结构之外都与图13所示的洗衣机401A相同,所以在相同的部分注上相同的附图标记并省略说明。Fig. 14 is a view showing a first modification of the washing machine 401 (401A) of the fourth embodiment shown in Fig. 13 . The same components as those of the washing machine 401A shown in FIG. 13 are denoted by the same reference numerals, and the description thereof will be omitted.
图14所示的洗衣机401B具备与图13所示的洗衣机401不同形状的曲面板482、以及被抵接块472。曲面板482尽管设置在与图13的曲面板481相同的位 置上,但是圆弧所成的角度放大到约180°。同样地,虽然被抵接块472也设置在与图13的被抵接块471相同的位置上,但是被抵接面472a所成的角度放大到约180°。The washing machine 401B shown in FIG. 14 is provided with a curved panel 482 having a shape different from that of the washing machine 401 shown in FIG. 13, and a contacted block 472. The curved panel 482 is disposed in the same position as the curved panel 481 of FIG. Set, but the angle formed by the arc is enlarged to about 180°. Similarly, although the abutted block 472 is also disposed at the same position as the abutted block 471 of Fig. 13, the angle formed by the abutting surface 472a is enlarged to about 180°.
因此,洗衣机401B通过设置在两个地方上的曲面板482和被抵接块472,能限制向以旋转轴Ra为中心的合计360°的方向的位移,无论对哪一个方向都能以相同的位移量抵接。因此,能进而提高上述的效果,能更顺利地使各个方向的压缩螺旋弹簧61发生作用,能更加适当地减少振动。Therefore, the washing machine 401B can restrict the displacement to the total of 360° centered on the rotation axis Ra by the curved panel 482 and the abutted block 472 provided at two places, regardless of which direction can be the same. The displacement amount is abutted. Therefore, the above-described effects can be further enhanced, and the compression coil springs 61 in all directions can be more smoothly operated, and the vibration can be more appropriately reduced.
图15为表示图13所示的第四实施方式的洗衣机401(401A)的第二变形例的图。因为除了后述的结构之外都与图13所示的洗衣机401A相同,所以在相同的部分注上相同的附图标记并省略说明。Fig. 15 is a view showing a second modification of the washing machine 401 (401A) of the fourth embodiment shown in Fig. 13 . The same components as those of the washing machine 401A shown in FIG. 13 are denoted by the same reference numerals, and the description thereof will be omitted.
图15所示的洗衣机401C中,与图13所示的洗衣机401形状相同的曲面板481以及被抵接块471设置于四处而不是两处。各曲面板481以及与其对置的被抵接块471分别配置于主体2的角落部2a1。进而,x方向弹性支承装置6x以及y方向弹性支承装置6y设置有与曲面板481对应的个数的量。In the washing machine 401C shown in Fig. 15, the curved panel 481 and the abutted block 471 having the same shape as the washing machine 401 shown in Fig. 13 are provided at four places instead of two. Each of the curved panels 481 and the abutted block 471 opposed thereto are disposed on the corner portion 2a1 of the main body 2, respectively. Further, the x-direction elastic support device 6x and the y-direction elastic support device 6y are provided in an amount corresponding to the number of the curved panels 481.
如上所述,因为曲面板481以及被抵接块471所成的圆弧的角度设定为120°附近,所以通过合计四处从而能覆盖360°以上的方向。因此,因为无论对哪一个方向都能以相同的位移量抵接,所以与上述的第一变形例相同,能更顺利地使各个方向的压缩螺旋弹簧61发生作用,可以适当地减少振动。As described above, since the angle of the circular arc formed by the curved panel 481 and the abutting block 471 is set to be around 120°, the direction of 360° or more can be covered by the total of four places. Therefore, since the same displacement amount can be abutted regardless of the direction, the compression coil spring 61 in each direction can be more smoothly operated as in the first modification described above, and the vibration can be appropriately reduced.
图16为表示图13所示的第四实施方式的洗衣机401(401A)的第三变形例的图。因为除了后述的结构之外都与图13所示的洗衣机401A相同,所以在相同的部分注上相同的附图标记并省略说明。Fig. 16 is a view showing a third modification of the washing machine 401 (401A) of the fourth embodiment shown in Fig. 13 . The same components as those of the washing machine 401A shown in FIG. 13 are denoted by the same reference numerals, and the description thereof will be omitted.
图16所示的洗衣机401D虽然具备与图13所示的洗衣机401相同形状的曲面板481以及被抵接块471,但是作为第二弹性支承装置306,使用第三实施方式中的弹性单元306A(参照图10、11)的结构与图13所示的洗衣机401不同。因此,能得到与上述相同的效果,并且能实现因为单元化而带来的组装工时的减少和小型化。The washing machine 401D shown in Fig. 16 includes the curved panel 481 and the abutted block 471 having the same shape as the washing machine 401 shown in Fig. 13, but the elastic unit 306A in the third embodiment is used as the second elastic supporting means 306 ( The structure of FIGS. 10 and 11) is different from that of the washing machine 401 shown in FIG. Therefore, the same effects as described above can be obtained, and reduction in assembly man-hours and miniaturization due to unitization can be achieved.
<第五实施方式><Fifth Embodiment>
图17(a)与上述的第一实施方式中的图2对应,是表示本发明的第五实施方式的洗衣机501的横剖图。因为除了后述的结构之外都与第一实施方式(图1~图5)所示的洗衣机1相同,所以在相同的部分注上相同的附图标记并省略说明。Fig. 17 (a) corresponds to Fig. 2 in the first embodiment described above, and is a cross-sectional view showing a washing machine 501 according to a fifth embodiment of the present invention. The same components as those of the first embodiment (FIGS. 1 to 5) are denoted by the same reference numerals, and the description thereof is omitted.
图17(a)所示的洗衣机501中,在第二弹性支承装置6的前端作为与外槽 3同轴配置的抵接部设置圆环状的限制构件581,以与其对置的方式在主体2设置被抵接板71,这一点与第一实施方式的洗衣机1(参照图2)不同。被抵接板71构成为与上述的第一实施方式的第二变形例(参照图7)相同。In the washing machine 501 shown in Fig. 17 (a), the front end of the second elastic supporting device 6 serves as an outer groove The abutting portion that is coaxially disposed is provided with the annular regulating member 581, and the abutting plate 71 is provided on the main body 2 so as to face the same, which is different from the washing machine 1 (see FIG. 2) of the first embodiment. The abutted plate 71 is configured in the same manner as the second modification (see FIG. 7) of the above-described first embodiment.
图17(b)为用于说明限制构件581的形状的立体图。限制构件581由圆环状的上板581a、与其下方平行配置的圆环状的下板581b、以及连接它们的外周侧的侧板581c构成,通过与z方向平行的平面切断时的剖面成为向内侧开口的“コ”字形。Fig. 17 (b) is a perspective view for explaining the shape of the restricting member 581. The restricting member 581 is composed of an annular upper plate 581a, an annular lower plate 581b disposed in parallel with the lower side thereof, and a side plate 581c connected to the outer peripheral side thereof, and the cross section when the plane parallel to the z direction is cut The "コ" shape of the inside opening.
使构成各个弹性支承装置6的压缩螺旋弹簧61的一端61a与外槽3的外表面32a(参照图3)连接,通过将构成前端的另一端61b收容于限制构件581的内侧从而与限制构件581连接。由于各个压缩螺旋弹簧61的另一端61b没有与侧板581c固定,因而限制构件581只在向压缩各个压缩螺旋弹簧61的方向位移的情况下变形。One end 61a of the compression coil spring 61 constituting each elastic support device 6 is connected to the outer surface 32a (see FIG. 3) of the outer groove 3, and the other end 61b constituting the front end is housed inside the restriction member 581 to be in contact with the restriction member 581. connection. Since the other end 61b of each compression coil spring 61 is not fixed to the side plate 581c, the restriction member 581 is deformed only in the case of being displaced in the direction of compressing the respective compression coil springs 61.
洗衣机501中限制构件581和被抵接板71同心状地配置,无论对以旋转轴Ra为中心的任一方向,都通过设定相当于第一实施方式中的间隙E(参照图3)的均匀的间隙,从而只要是相同的位移量,就即使在外槽3在任一方向位移的情况下,都能适当地使限制构件581和被抵接板71抵接。然后,通过限制构件581,能压缩构成第二弹性支承装置6的压缩螺旋弹簧61使其变形。进而,通过共用的限制构件581产生变形,由此能根据外槽3的位移方向的变化,使作用的第二弹性支承装置6顺利地变化。因此,在外槽3回旋时,能更顺利地减少其振动。In the washing machine 501, the regulating member 581 and the abutted plate 71 are arranged concentrically, and the gap E (see FIG. 3) corresponding to the first embodiment is set in any direction around the rotation axis Ra. Even if the gap is uniform, the restriction member 581 and the abutted plate 71 can be appropriately brought into contact even when the outer groove 3 is displaced in either direction as long as the displacement amount is the same. Then, by the restricting member 581, the compression coil spring 61 constituting the second elastic supporting device 6 can be compressed to be deformed. Further, deformation is caused by the common restricting member 581, whereby the second elastic supporting device 6 that acts can be smoothly changed in accordance with the change in the displacement direction of the outer tub 3. Therefore, when the outer tank 3 is rotated, the vibration can be more smoothly reduced.
以上,关于本发明的实施方式进行了说明,但是各部的具体的结构不是仅限定于上述的实施方式。Although the embodiments of the present invention have been described above, the specific configurations of the respective components are not limited to the above-described embodiments.
例如,在上述的实施方式中,将第二弹性支承装置6(306)和构成它的压缩螺旋弹簧61(361A)一起沿着x方向或者y方向设置,在xy平面内互相正交地配置,但由这些所得的合力只要是在中心方向上,就不是必须为上述的方向。即,各个第二弹性支承装置6(306)与旋转轴Ra交叉,并且只配置在相互交叉的方向上就足够了。进而,也不是说必须将第二弹性支承装置6(306)设置在四处,最少只设置在三处就足够了。此外,也不是必须要沿着xy平面配置,也可以配置在朝向稍微上方或者下方等、包括z方向的成分的倾斜方向上。For example, in the above-described embodiment, the second elastic supporting device 6 (306) and the compression coil spring 61 (361A) constituting the same are disposed along the x direction or the y direction, and are arranged orthogonally to each other in the xy plane. However, the resultant force from these is not necessarily the above direction as long as it is in the center direction. That is, it is sufficient that each of the second elastic supporting means 6 (306) intersects with the rotation axis Ra and is disposed only in a direction crossing each other. Further, it is not necessary to say that the second elastic supporting means 6 (306) must be disposed at four places, and it is sufficient to set at least three places. Further, it is not necessarily arranged along the xy plane, and may be arranged in an oblique direction including components in the z direction, such as slightly upward or downward.
进而,在上述的实施方式中,虽然外槽3构成为将内部支承的内槽作为洗涤脱水槽4,但是本发明在需要内槽的高速旋转的情况下能优选地利用,即使内 槽仅为洗涤槽或脱水槽也能应用上述的结构。Further, in the above-described embodiment, the outer tank 3 is configured such that the inner tank supported internally serves as the washing and dewatering tank 4. However, the present invention can be preferably utilized even when high-speed rotation of the inner tank is required, even if The above structure can also be applied to the tank only for the washing tank or the dewatering tank.
除此之外,在上述的实施方式中,使外槽3的轴向朝向z方向、即垂直方向,但即使是朝向斜上方的方式也同样能应用本发明。此外,即使是外槽3的轴向为水平方向的滚筒型洗衣机,也能优选地利用本发明。In addition, in the above-described embodiment, the axial direction of the outer tub 3 is oriented in the z direction, that is, in the vertical direction, but the present invention can be applied similarly even to the obliquely upward direction. Further, the present invention can be preferably used even in a drum type washing machine in which the axial direction of the outer tub 3 is horizontal.
