Abstract

本实用新型涉及洗衣机滚筒悬挂装置,减震器分别通过销轴与外筒和箱体连接;箱体下部前端设有加强板。本实用新型提供了一种提升悬挂系统整体刚度,避免在脱水过程中产生共振的洗衣机悬架装置。

Description

洗衣机滚筒悬挂装置
技术领域
本实用新型涉及洗衣机悬挂装置。
背景技术
传统的全自动斜开式滚筒洗衣机箱体悬挂系统,由于箱体悬挂系统采用拼装结构,侧板通过连板连接,滚筒洗衣机运动部件外桶通过吊簧、减震器与箱体悬挂系统连接,在工作过程中,外桶能量通过吊簧、减震器传导到箱体悬挂系统,原有箱体悬挂系统的共振频率在正常的脱水转速内,长时间在共振频率工作不仅引起整机震动大,还会大大缩短整机的寿命,引起部件失效。
实用新型内容
本实用新型针对现有技术的不足,设计开发出来一种提升悬挂系统整体刚度,避免在脱水过程中产生共振的洗衣机悬架装置。
本实用新型是通过以下技术方案实现的:
洗衣机滚筒悬挂装置,减震器分别与外筒和箱体连接,所述的减震器分别通过销轴与外筒和箱体连接。
洗衣机滚筒悬挂装置,所述的箱体下部设有加强板。
洗衣机滚筒悬挂装置,所述的箱体下部前端设有加强板。
原减震器与外桶及箱体的连接为紧固连接,外桶通过减震器与箱体的刚性加强,在脱水过程中从外桶向箱体传导的能量较大,改动后减震器与箱体、外桶的连接为销轴连接,使连接改为柔性连接,减小力的传导。通过对箱体悬挂系统的模态分析,在箱体前下部增加前下加强板,改变系统的刚度,使整机的共振频率发生偏移,有原有的12.5Hz改变到20Hz,使只在工作过程中不会达到共振频率。
附图说明
图1为减震器与箱体和外桶连接处的局部结构示意图。
图2为机体正面纵剖结构示意图。
具体实施方式
参见附图1所示。洗衣机减震器2分别通过销轴3与外筒1和箱体4连接。使减震器2与外筒1和箱体4的连接改为柔性连接,减小力的传导。参见附图2所示。洗衣机箱体4下部前端设有加强板5。在箱体4前下部增加前下加强板5,改变系统的刚度,使整机的共振频率发生偏移,有原有的12.5Hz改变到20Hz,使只在工作过程中不会达到共振频率。
