Description

Rack assembly and oven comprising the same

The present invention relates to an oven, and more particularly, to a rack assembly on which a cooked food is seated and an oven including the same.

An oven is an electrical appliance which cooks food using electricity or gas. The electric oven is provided with an oven chamber for cooking food. And in the oven chamber, a rack assembly on which the food is seated is detachably installed. In addition, both side surfaces of the oven chamber is provided with a plurality of guide ribs for supporting the rack. The protrusions are provided on both sides of the oven chamber to be spaced up and down by a predetermined distance. The rack assembly is mounted to the inside of the oven chamber by being supported by the guide ribs whose both ends are set at a set height according to a cooking mode.

The rack may be divided into a rack of standard type and a rack of telescopic type. In the rack of the standard type, both end portions thereof are supported by guide ribs provided on both sides of the oven chamber. In the case of a telescopic rack, a guide rack provided at both sides of the oven chamber includes a mounting rack having both end portions thereof supported, and a draw rack which slides along the mounting rack to be drawn out of the oven chamber. Therefore, according to the telescopic rack, the withdrawal rack on which the food is actually seated is drawn out of the oven chamber, so that the user can easily put the food in and out of the oven chamber.

However, the following problems arise in such a conventional oven.

The oven is provided with a heater for heating food and cooking the upper and lower surfaces or the rear surface thereof. And the heater radiantly heats the food seated on the upper surface of the rack. Therefore, one guide rib of which the rack is supported among the guide ribs is determined according to a distance between the food seated on the upper surface of the rack and the heater, which are preset according to a cooking method.

However, in a state in which the rack of the standard type and the rack of the telescopic type are supported in the oven chamber, the distance between the upper surface or the lower surface of each of the upper and lower surfaces of the oven chamber is different. In other words, in the rack of the standard type, both end portions thereof are supported by the guide ribs, and food is placed on the upper surface thereof. Therefore, the height of the food seated on the upper surface of the rack of the standard type is equal to the height of the guide rib. However, in the telescopic rack, both side ends of the mounting rack are supported by the guide rib, and food is seated on the upper surface of the draw rack. Therefore, the height of the food seated on the telescopic type is different from the height of the guide rib.

Therefore, even though the rack of the standard type and the rack of the telescopic type are supported by any one of the guide ribs according to the cooking method, the distance between the food seated on the upper surface and the heater is different. Therefore, separate mounting racks are provided on both sides of the oven chamber or the output of the heater is corrected in order to correct a difference in distance between the food and the heater seated on the upper surface of the rack of the standard type or the telescopic type. There are disadvantages to be followed.

Also, conventionally, both bottom ends of the bottom of the standard type rack or both bottom ends of the mounting rack of the rack of the telescopic type are simply supported by the guide ribs. Therefore, the rack supported by the guide rib may be inclined by the load of the food seated on the upper surface of the rack. In particular, in the case of the telescopic rack, such a phenomenon may occur in the process of sliding the draw rack on which food is seated with respect to the mounting rack.

The present invention is to solve the problems caused by the prior art as described above, an object of the present invention is to provide a rack assembly and an oven comprising the same so as to be able to use a variety of racks more easily.
