Description

WIRE SHELF FOR USE IN AN OVEN HAVING SIDE WIRE RACKS

The present invention relates to an oven. The present invention more particularly relates to an oven having a grill function.

Cooking appliances such as ovens are commonly known in the art. An oven generally comprises a cooking chamber for cooking the food; a heating unit for heating the cooking chamber; and a pair of side wire racks for supporting a wire shelf. The side wire racks are disposed onto the side walls of the cooking chamber. Each side wire rack has one or more support wires each for bearing the wire shelf at the respective level. The user mounts the wire shelf it into the cooking chamber by means of the side wire racks, and places the food to be cooked onto the wire shelf.

WO2007/077163 A1 discloses an oven.

A problem with the prior art oven is that the user cannot smoothly align and securely mount the wire shelf to the side wire racks. The user generally hits with the corner of the wire shelf the side walls of the cooking chamber. In such instances, the surface of the sidewalls can be easily damaged, and thus the cleaning of the side walls becomes more difficult. Moreover, the mounting of the wire shelf becomes more complicated due to the frictional forces between the side walls and the wire shelf, and thus the user can easily skew or tilt the wire shelf and cause an accident. Such incidents are likely to happen when the cooking chamber is hot and the user must quickly mount the wire shelf so as to avoid excessive exposure to heat.

An objective of the present invention is to provide a wire shelf for use in an oven which solves the aforementioned problems of the prior art in a cost-effective way and which enables a smooth and safe mounting/dismounting of the wire shelf.

This objective has been achieved by the wire shelf as defined in claim 1, and the oven as defined in claim 4. Further achievements have been attained by the subject-matters respectively defined in the dependent claims.

The wire shelf of the present invention comprises: a rectangular frame which includes two side wires which are adapted to be slidably received onto the support wires of the side wire racks respectively; a front wire and a rear wire which respectively join the front ends of the side wires and the rear ends of the side wires, wherein the front wire and the rear wire each has a sunken section which is centered, and wherein the rising edges of the sunken sections are immediately adjacent to the support wires respectively and adapted to block the side wires from moving sideways and contacting the respective side wall; and a grid for supporting the food, wherein the grid is joined to the bottom of the sunken sections respectively.

A major advantageous effect of the present invention is that the wire shelf can be smoothly aligned without hitting the side walls of the cooking chamber by virtue of the rising edges of the sunken sections. Thereby, the side walls can be prevented from being contacted by the wire shelf, and thus the risk of scratching the side walls can be eliminated. Thereby, also the wire shelf can be easily slid into and out of the cooking chamber without tilting and skewing the same, and thus the risk of causing an accident can be eliminated or reduced as much as possible. Another major advantageous effect of the present invention is that the wire shelf can be stably mounted to the side wire racks by virtue the sunken sections which lower the center of gravity, and thus the food can be maintained more stably on the support wires. Another major advantageous effect of the present invention is that the wire shelf can be easily produced by virtue of the rectangular frame which defines a closed single wire. Thereby, the overall costs can be reduced both in terms of material and labor. With the present invention, the user satisfaction can be increased.

In an embodiment, the grid has plurality of intermediate wires which are located between the side wires of the rectangular frame. The intermediate wires extend parallely and into the cooking chamber. This embodiment is particularly advantageous as the articles on the grid can be more easily moved or specifically slid into or out of the cooking chamber while being securely kept in contact with the intermediate wires. Thereby the user can save the laborious lifting of the articles from the grid and also avoid accidentally touching the hot parts. This embodiment is also particularly advantageous as the area utilization efficiency of the wire shelf can be increased by arranging the intermediate wires at predetermined intervals over the entire sunken section.

In another embodiment, the intermediate wires are welded onto the bottom of the sunken sections respectively. This embodiment is particularly advantageous as the front wire and the rear wire prevent the articles from falling off the grid. Thereby also the upper surfaces of the front wire and the rear wire can be more smoothly cleaned.

In another embodiment, the rectangular frame is provided in form of a closed single wire. This embodiment is particularly advantageous as the wire shelf can be more easily produced, and the overall costs can be reduced both in terms of labor and material.

In another embodiment, each rising edge has a rectangular stepped shape. This embodiment is particularly advantageous as the wire shelf can be more stably and securely held in place, and thus the risk of accidentally dislodging the wire shelf out of the support wires can be eliminated or reduced as much as possible.

In another embodiment, a guard wire is disposed onto the rear wire of the rectangular frame so as to block rearward movement of the articles on the grid. This embodiment is particularly advantageous as the articles can be prevented from falling off when the wire shelf is suddenly pulled out of the cooking chamber.

In another embodiment, the wire shelf only includes the rectangular frame, the grid including the intermediate wires and the guard wire. This embodiment is particularly advantageous as the wire shelf can be more easily produced, and the overall costs can be reduced both in terms of labor and material.

In other alternative embodiments, the wire shelf can be used in an oven having a convectional heating function and/or a microwave heating function. As the wire shelf is prevented from contacting the side walls, the risk of spark generation and damages to the enameled surfaces can be eliminated.

Additional features and additional advantageous effects of the wire shelf and the oven of the present invention will become more apparent with the detailed description of the embodiments with reference to the accompanying drawings in which:
