Abstract

A slide-in or drop-in cooking range includes an upper cooktop in the form of a module suspended above an oven cavity. For installation purposes, the upper cooktop can be vertically repositioned relative to the oven cavity to assure proper alignment with the countertop and avoid damage to the cooktop as a result of combined thermal and mechanical stresses over time. The disclosure is particularly applicable to ranges employing glass cooktops having a periphery designed to rest upon edge portions of a countertop and contemplates various mechanisms to perform the cooktop repositioning function, including select mechanisms for locking, ratcheting and biasing the cooktop to establish a desired vertical position for the cooktop.

First claim

I claim:

1. A cooking appliance comprising:
a cabinet;
an oven cavity mounted in the cabinet;
a cooktop positioned above the oven cavity; and
a mechanism interconnecting the cooktop to the cabinet while permitting the cooktop to be vertically adjusted relative to the oven cavity to selectively alter the vertical spacing between the cooktop and the oven cavity for different mounting configurations, wherein the mechanism supports the cooktop in each of the different mounting configurations, and wherein the mechanism is constituted by a ratcheting mechanism interconnecting the cooktop to the cabinet.

2. The cooking appliance according to claim 1 , wherein the cooktop is constituted by a module, including a control panel and a glass panel provided with a plurality of heating elements, mounted upon the cabinet.

3. The cooking appliance according to claim 1 , wherein the mechanism is constituted by a plurality of notch elements provided on the cooktop and a bar removably connected to the cabinet for engaging the plurality of notch elements.

4. The cooking appliance according to claim 3 , wherein the bar is pivotally attached for movement relative to the cabinet.

5. The cooking appliance according to claim 1 , wherein the cooking appliance constitutes a range mounted within a cut-out portion of a countertop and the cooktop includes a panel which extends over edge portions of the countertop.

6. A cooking appliance comprising:
a cabinet;
an oven cavity mounted in the cabinet;
a cooktop positioned above the oven cavity; and
a mechanism interconnecting the cooktop to the cabinet while permitting the cooktop to be vertically adjusted relative to the oven cavity to selectively alter the vertical spacing between the cooktop and the oven cavity for different mounting configurations, wherein the mechanism supports the cooktop in each of the different mounting configurations, and wherein at least a portion of the mechanism is provided along a side of the cabinet.

7. The cooking appliance according to claim 6 , further comprising a locking mechanism for fixing the cooktop in a select vertical position relative to the oven cavity.

8. The cooking appliance according to claim 6 , wherein the mechanism includes at least one spring acting between the cooktop and the cabinet.

9. The cooking appliance according to claim 8 , wherein the at least one spring applies a downward biasing force upon the cooktop.

10. The cooking appliance according to claim 9 , wherein the at least one spring is a tension spring.

11. A method of mounting a range, including a lower oven cavity and an upper cooktop, in an opening provided along a countertop comprising:
initially suspending the upper cooktop above the lower oven cavity by an adjustable interconnecting mechanism;
sliding the range, including both the lower oven cavity and the upper cooktop, within the opening; and
vertically adjusting, using the adjustable interconnecting mechanism, the upper cooktop relative to the lower oven cavity.

12. The method of claim 11 , wherein the range is positioned within the opening, with the lower oven cavity being exposed below the countertop and at least a panel of the upper cooktop resting upon edge portions of the countertop.

13. The method of claim 12 , further comprising: simultaneously vertically adjusting oven controls with the upper cooktop relative to the lower oven cavity.

14. The method of claim 12 , further comprising: locking the upper cooktop in a select vertical position relative to the oven cavity prior to positioning the range within the opening.

15. The method of claim 12 , further comprising: lowering the upper cooktop onto the countertop after positioning the range within the opening.

16. The method of claim 15 , wherein lowering of the upper cooktop is performed by ratcheting the upper cooktop to a lowered position.

17. The method of claim 11 , further comprising: biasing the upper cooktop into engagement with the countertop.
