Innovative Balancer Design for Washing Machine Inner Tubs
Here’s PatSnap Eureka !
Summary
Problems
Conventional washing machines with balancers mounted on the outer surface of the inner tub are complex and costly to manufacture, and do not directly improve washing performance, as they require a separate metal front surface part and do not effectively address unbalance and noise issues.
Innovation solutions
A washing machine design where the balancer is directly mounted on the inner tub's body without a front surface part, using a cylindrical body with a balancer connected to the inner diameter part to reduce unbalance and reinforce the body, and incorporating blades to enhance washing performance by contacting laundry and generating a water current.

General conflict description:
Principle concept:
If a separate metal front surface part is used to mount the balancer, then the balancer can be securely mounted, but the manufacturing process becomes complex and manufacturing costs increase
Why choose this principle:
The balancer housing is merged with the front surface part of the inner tub, forming an integrated structure. The balancer mounting plate is directly formed on the front surface of the cylindrical drum body, eliminating the need for a separate front surface part. This integration reduces the number of components and simplifies the manufacturing process while maintaining secure balancer mounting.
Principle concept:
If a separate metal front surface part is used to mount the balancer, then the balancer can be securely mounted, but the manufacturing process becomes complex and manufacturing costs increase
Why choose this principle:
The front surface part of the cylindrical drum body serves multiple functions: it acts as both the structural front closure of the drum and as the mounting base for the balancer. The mounting plate formed on this surface provides both structural reinforcement and balancer attachment functionality, demonstrating multi-functionality that reduces overall component count.

Abstract
Disclosed herein is a washing machine in which a balancer is directly mounted on a body of an inner tub without a front surface part of the inner tub. The washing machine includes an outer tub to store water, a body formed in a cylindrical shape provided with an opening at one surface thereof and provided in the outer tub, and a balancer connected to an inner diameter part at the opening of the body to reduce unbalance of the body generated during rotation of the body and to reinforce the body.
