Abstract

An oven having a cabinet and a cooktop disposed above the cabinet is provided. The cooktop includes a top frame located at a top surface of the cabinet, the top frame including at least one heater installation opening and at least two heater support brackets adjacent the installation opening, a top plate located on a top surface of the top frame, and a heater located in the installation opening, the heater including at least two heater support holders, each support holder being elastically coupled to a corresponding support bracket to movably support the heater.

First claim

What is claimed is:

1. An oven comprising:
a cabinet; and
a cooktop disposed above the cabinet, the cooktop including:
a top frame located at a top surface of the cabinet, the top frame including at least one heater installation opening and at least two heater support brackets adjacent the installation opening;
a top plate located on a top surface of the top frame; and
a heater located in the installation opening, the heater including at least two heater support holders, each heater support holder being elastically coupled to a corresponding heater support bracket to movably support the heater,

wherein each heater support holder comprises an insertion part with a hook part,
wherein each heater support bracket comprises an extension part extending downward from a side of the top frame, and a support part extending perpendicularly with respect to the extension part and having an insertion slot, and
wherein the insertion part upwardly passes through the insertion slot at a lower side of the extension part.

2. The oven according to claim 1 , wherein each heater support bracket is integrally formed with the top frame.

3. The oven according to claim 1 , wherein
the hook part is hooked on a side of the heater support bracket when the insertion part is inserted into the insertion slot.

4. The oven according to claim 3 , wherein the hook part is elastically deformed when the insertion part is inserted into the insertion slot.

5. The oven according to claim 1 , wherein at least a portion of each of the heater support holders is rounded with a preset curvature.

6. The oven according to claim 1 , wherein
each heater support holder further includes:
a fixing part fixed to a side of the cooktop heater;
a contact part disposed under the fixing part; and
a connection part connecting the fixing part to the contact part, and

wherein the insertion part is extended from a side of the connection part.

7. The oven according to claim 6 , wherein the connection part is rounded with a preset curvature.

8. The oven according to claim 6 , wherein the hook part is elastically deformed when the insertion part is inserted into the insertion slot.

9. The oven according to claim 1 , wherein each of the heater support brackets and heater support holders are elastically coupled to each other and fixed by a coupling unit.

10. An oven comprising:
a cabinet; and
a cooktop disposed above the cabinet, the cooktop including:
a top frame located at a top surface of the cabinet, the top frame including a plurality of heater installation openings and at least two heater support brackets adjacent each of the installation openings;
a top plate located on a top surface of the top frame; and
a plurality of heaters, each heater located in a corresponding heater installation opening, each heater including at least two heater support holders, each of the heater support holders being elastically coupled to corresponding heater support brackets to movably support the heater,
wherein each of the heater support holders comprises an insertion part with a hook part,
wherein each of the heater support brackets comprises an extension part extending downward from a side of the top frame, and a support part extending perpendicularly with respect to the extension part and having an insertion slot, and
wherein the insertion part upwardly passes through the insertion slot at a lower side of the extension part.

11. The oven according to claim 10 , wherein the extension part extends perpendicular to the top frame.

12. The oven according to claim 11 , wherein at least a portion of each of the heater support brackets is positioned in a corresponding heater installation opening.

13. The oven according to claim 10 , wherein each of the plurality of heaters includes:
a heater base on which the heater support holders are disposed; and
a heat generation unit disposed on a top surface of the heater base.

14. The oven according to claim 13 , wherein each of the heater support holders is welded to a flange of the heater base.

15. The oven according to claim 10 , wherein at least a portion of each of the heater support holders is rounded with a preset curvature to elastically support the heater on the top frame.

16. The oven according to claim 10 , wherein
each of the heater support holders includes:
a fixing part fixed to one heater of the plurality of heaters;
a contact part in which at least portion thereof is disposed outside said one heater, the contact part being disposed under the fixing part;
a connection part connecting the fixing part to the contact part, and
wherein the hook part is bent with respect to the insertion part after a portion of the insertion part is cut, the hook part being elastically deformable with respect to the insertion part when the insertion part is inserted into the insertion slot so as to return to an initial position thereof when the insertion part is completely inserted into the insertion slot.

17. The oven according to claim 10 , wherein a coupling hole is provided in each of the heater support brackets,
a through-hole is provided in each of the heater support holders, and
a coupling unit passes through the through-hole and is coupled to the coupling hole.
