Description

Automatic Transfer Device for Rangehood Drawer

The present invention is an invention related to the automatic transfer device of the range hood take-out plate to enable automatic withdrawal and insertion of the range hood take-out plate.

In general, the range hood is fixedly installed on the wall or cabinet above the kitchen counter together with the upper cabinet of the kitchen. In the range hood having the same suction volume, it is necessary to enlarge the collection area in order to inhale and discharge odor and harmful gas more effectively, but the width of the range hood is limited by the upper cabinet of the kitchen. Although the size of the range hood is usually installed at the level of the user's eyes on the kitchen counter, when the size of the range hood becomes larger than the vertical size of the countertop, it causes inconvenience to cooking and the range hood takes up more space than necessary.

In order to eliminate such inconveniences, a method of increasing the collecting area by manually or automatically drawing out the drawing board of the range hood has been devised. However, in the case of the conventional drawing board conveying device, the drawing plate is slide on the body of the range hood. Looking at the way the movement is coupled, only a pair of slide rails (Slide Rail) is coupled to both ends of the drawer is in the form of guiding the transport movement of the drawer.

Therefore, if the horizontal width of the range hood and the drawer plate extends beyond the predetermined value, the pull-out can be pulled out by hand or automatically drawn out using a separate power transmission device. There was a problem that the automatic withdrawal device does not operate due to excessive concentration or withdrawal is not made smoothly or excessive load.

The purpose of the present invention devised to solve the above problems is as follows.

First, the object of the present invention is to provide a means for automatically withdrawing the drawing board in order to increase the collection area of the range hood.

Second, by providing a means for automatically inserting the drawboard of the range hood to provide a means for improving the effective use of the indoor pollution source and the space utilization of the kitchen to provide a comfortable residential environment.

Third, another object of the present invention is to provide an automatic feed device for a range hood including an X-type link in order to facilitate the automatic transfer operation of the range hood draw plate.

Fourth, another object of the present invention is to improve the durability and reliability of the product by providing an automatic transfer device of a range hood drawer that operates smoothly even with a small force.
