Abstract

The present invention provides an oven including an oven body with an exhaust port and a heat transfer assembly, disposed at a side of the oven body, that includes a top plate and a bottom plate connected by two side plates, and a sealing plate to form an air passage therebetween. The air passage has a first opening near the sealing plate and a second opening away from the sealing plate. The first opening communicates with the exhaust port of the oven body, and the second opening opens to the external of the heat transfer assembly which is arranged so the hot air from the exhaust port may enter the interior of the heat transfer assembly so that the heat energy of the hot air can be absorbed by the top plate and then conducted to the food materials on the top plate to be reused.

First claim

What is claimed is:

1. An oven comprising:
an oven body having an exhaust port; and
a heat transfer assembly disposed at a side of the oven body and including a top plate, a bottom plate, two side plates, and a sealing plate, wherein the top plate and the bottom plate are connected by the two side plates and the sealing plate to form a guiding duct, in which an air passage surrounded by the top plate, the bottom plate, the two side plates, and the sealing plate are defined; and the air passage has a first opening near the sealing plate and a second opening away from the sealing plate, wherein the first opening communicates with the exhaust port of the oven body and the second opening opens to the external of the heat transfer assembly;
wherein the side plates and the sealing plate extend from the bottom plate straight upward to contain top edges which are higher than the outer surface of the top plate, a receiving trough surrounded by protruding portions of the side plates and the sealing plate is formed on the outer surface of the top plate and is adapted to receive an object;
the top plate of the heat transfer assembly ducts the heat energy of a hot air generated by the oven body and flowing through the air passage to an outer surface of the top plate and to the object;
wherein the side plates and the sealing plate do not overlap with the the outer surface of the top plate,
wherein the top plate is arranged in a tilted manner such that one end of the top plate connecting the sealing plate is closer to the bottom plate than the other end of the top plate away from the sealing plate,
wherein the heat transfer assembly further comprises an extension duct communicating with the guiding duct through the second opening, the guiding duct has a first axis extending along its longitudinal direction, the extension duct has a second axis extending along its longitudinal direction, and an angle is formed between the first axis and the second axis,
wherein the heat transfer assembly further comprises at least one partition in the extension duct away from the second opening,
and wherein the bottom plate has at least one outlet adjacent to the second opening and opening to the external of the heat transfer assembly.

2. The oven according to claim 1 , further comprising a thermal insulating cover mounted on the top plate to form a heat preserving space between the thermal insulating cover and the top plate.

3. The oven according to claim 1 , wherein the heat transfer assembly includes a plurality of heat conducting members, each of which has a heat conducting portion coupled to an inner surface of the top plate and a heat absorbing portion connected to the heat conducting portion for contacting the hot air in the air passage.

4. The oven according to claim 3 , wherein the heat conducting members are distributed along a flow direction of the hot air flowing through the air passage.

5. The oven according to claim 1 , wherein the heat transfer assembly is disposed above the oven body, and the first opening is in communication with the exhaust port through at least one tube sleeve.

6. The oven according to claim 1 , further comprising a bracket adapted to elevate the bottom plate such that the bottom plate is substantially parallel to the oven body.

7. The oven according to claim 1 , further comprising a vertical pipe adjacent to the heat transfer assembly, wherein the vertical pipe has an upper opening and a lower opening, between which a portion of the vertical pipe communicates with the second opening.

8. The oven according to claim 1 , wherein the extension duct is provided with a plurality of perforations near the guiding duct.

9. The oven according to claim 1 , further comprising at least one partition mounted between the two side plates and adjacent to the second opening.
