Description

また、ドア降下手段は、一端がドアに固定されて、ドアを下方に牽引する線形体と、線形体の他端が固定されて、線形体が巻き付けられる巻取り部と、巻取り部を回転させるモータと、を備える。
このような構成は、自動開閉機構の簡易化に寄与する。 Further, the door dropping means has one end fixed to the door, and a linear body for pulling the door downwards, and the other end of the linear member is fixed, and a take-up unit for linear body is wound, the winding Ri portion A rotating motor.
Such a configuration contributes to simplification of the automatic opening / closing mechanism.

更に、食器洗浄機１は、自動でドア７を上下に開閉させるための自動開閉機構４０を備えている。この自動開閉機構４０は、ドア７を常に開放状態にするように付勢する圧縮バネ２３，２４と、ドア７を圧縮バネ２３，２４の付勢力に抗して下降させるドア降下手段Ｒと、を有している。このドア降下手段Ｒは、ドア７の上部に設けられたブラケット４１に上端が固定されると共に、圧縮バネ２３，２４の付勢力に抗してドア７を下方に緊張状態で牽引する線形体４２と、線形体４２の下端が固定されて、線形体４２が巻き付けられる巻取り部４３と、ブラケット４５によって洗浄機本体２の下側部分２ｂの背面に固定されて、巻取り部４３を所望の速度で正逆回転させるギアドモータ４４と、を備えている。 Furthermore, the dishwasher 1 includes an automatic opening / closing mechanism 40 for automatically opening and closing the door 7 up and down. The automatic opening / closing mechanism 40 includes compression springs 23 and 24 that urge the door 7 to be always open, door lowering means R that lowers the door 7 against the urging force of the compression springs 23 and 24, and have. The door lowering means R is fixed at a top end to a bracket 41 provided on the upper portion of the door 7 and linearly pulls the door 7 in a tensioned state against the urging force of the compression springs 23 and 24. When, is fixed the lower end of the linear body 42, a winding portion 43 for a linear body 42 is wound, is fixed to the rear surface of the lower portion 2b of the washing machine body 2 by a bracket 45, a winding Ri 43 desired And a geared motor 44 that rotates in the forward and reverse directions.

Claims

In a dishwasher equipped with an automatic opening and closing mechanism that moves the door up and down,
