Benefits of technology

[0009] An object of the present invention is to provide a heater assembly of a washing machine having convenience in maintenance and stability and reliability in operation.
[0018] The present invention mentioned above improves stability / reliability and convenience of maintenance in the heater assembly for the washing machine.

Problems solved by technology

Consequently, the maintenance of the heater is difficult and requires much time.
Accordingly, the cavity is different in a water pressure from the bottom surface of the outer tub, and thus the washing water could not be properly supplied to the inner tub from the outer tub.
In addition, if the heater is overheated, elements near the heater could be damaged and a fire might be occurred.
Further, as terminals of the heater project out of the outer tub, a short circuit and a fire thereby might be occurred.

Description

[0001] This application claims the benefit of Korean Application Nos. P2004-46010; P2004-46011 and P2004-46012, three of which are filed on Jun. 21, 2004, which are hereby incorporated by reference as if fully set forth herein. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a washing machine, and more particularly a heater assembly installed in the washing machine to heat washing water. [0004] 2. Discussion of the Related Art [0005] As well known, a washing using hot water enhances a washing efficiency, and for such reason, the hot water is generally supplied to the washing machine from an outside of the washing machine. However, recently, the heater is provided to the washing machine in order to directly heat the washing water. [0006] In most cases, the heater is mounted with brackets on a bottom of an inside of an outer tub which stores the washing water. The heater generates heat depending on washing conditions such as kind of...
