Description

This application claims the benefits of the Taiwan Patent Application Serial NOs. 102212856 and 102212857 filed on Jul. 8, 2013, the subject matters of which are incorporated herein by reference.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a window assembly, more particularly to a transparent window assembly, which includes a first hollow frame with an engagement groove, a second hollow frame and a transparent element clamped between the first and second hollow frames.

2. Description of the Prior Art

We generally keep an article or a half-finished product, such as camera or an experiment sample, within a moisture-proof cabinet or drying oven in order to prevent that specific article from being damaged due to humidity in the atmosphere. To facilitate viewing of the specific article kept therein without opening the window of the cabinet, a transparent window assembly is usually installed on the cabinet. In addition, the transparent window assembly is also mounted on a drying oven to facilitate observation of an object kept the drying oven.

During the mass production of the moisture-proof cabinet or drying oven, some production tables, likes times and batch number are usually stuck on the transparent window assembly by the production operator. Since the mass production is carried under the intensive temperature, the stuck table after removal often left a scar on the transparent window assembly, which, in turn, hinders the viewing of the interior of the drying oven. In order to eliminate this defect, the present technique utilizes a holding frame with a clamping section projecting outwardly and integrally therefrom and defining a clamping space therebetween. A production table can be clamped by the clamping section and the transparent window.

In addition, in case the transparent window assembly is installed on the moisture-proof cabinet, the latter only requires a piece of transparent element owing to its lower temperature thereof. On the contrary, a drying oven may require more that one piece of transparent element in order to maintain the high temperature therein. Generally, thick transparent element or multi layers of transparent element are provided in order to maintain the high temperature therein. Increase in the thickness or layers of transparent element needs an altered or new design.
