Patent Application
20250035317
The present disclosure generally relates to a cooking appliance and, more specifically, to a gasket that provides a seal between the cooktop surface and the upswept portion of the cooking appliance. Water, cleaning products, fluids, food, and other contaminants can potentially enter the interface between the rear edge of the cooktop surface and the upswept section of the cooking appliance. Those contaminants can cause damage to the internal components of the appliance and to the cooktop surface. Thus, a gasket that provides a seal that can accommodate different gaps between the cooktop surface and the appliance would potentially reduce entry of contaminants at that interface.
According to one aspect of the present disclosure is a gasket for a cooktop unit having an upswept section extending adjacent to the rear of the cooktop unit. The cooktop unit has cooktop housing has a front surface, rear surface, and two side surfaces. A gasket groove is located in the upswept section. The gasket is single piece gasket having a rigid section and a flexible section, the rigid section including a projection that is received in the gasket groove, and the flexible section including a curved section and a sealing section that contacts a cooktop surface coupled to the cooktop housing.
According to another aspect of the present disclosure is a cooktop unit having an upswept section extending adjacent to the rear of the cooktop unit. The cooktop unit has a cooktop surface coupled to the cooktop unit. A gasket groove is located in the upswept section, the gasket groove extending adjacent to the entire length of the cooktop surface. A gasket is a single piece gasket having a rigid section and a flexible section, the rigid section including a projection that is received in the gasket groove, and the flexible section including a curved section and a sealing section that contacts the cooktop surface.
According to yet another aspect of the present disclosure is an appliance having a cooktop surface that extends over each lateral side of the appliance. A gasket groove is located in a rear portion of the appliance adjacent to the cooktop surface. A gasket has a rigid section and a flexible section, the rigid section including a projection that is received in the gasket groove, and the flexible section including a curved section and a sealing section that contacts the cooktop surface.
These and other features, advantages, and objects of the present disclosure will be further understood and appreciated by those skilled in the art by reference to the following specification, claims, and appended drawings.
In the drawings:
The components in the figures are not necessarily to scale, emphasis instead being placed upon illustrating the principles described herein.
The present illustrated embodiments reside primarily in combinations of method steps and apparatus components related to a gasket for a cooking appliance. Accordingly, the apparatus components and method steps have been represented, where appropriate, by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present disclosure so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein. Further, like numerals in the description and drawings represent like elements.
For purposes of description herein, the terms “upper,” “lower,” “right,” “left,” “rear,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the disclosure as oriented in
The terms “including,” “comprises,” “comprising,” or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. An element preceded by “comprises a . . . ” does not, without more constraints, preclude the existence of additional identical elements in the process, method, article, or apparatus that comprises the element.
Referring to
The cooktop surface 10 is illustrated as extending to the side edges 4 of the cooking appliance 2. The side edges 12 of the cooktop surface 10 extend to and/or over the side edges 4 of the cooking appliance 2 creating an edge to edge cooktop surface 10. The top surface 30 of the cooktop surface 10 can be entirely flat, as shown in
In the illustrated embodiments, the cooking appliance 2 includes an upswept section 20 that is adjacent to the rear edge 16 of the cooktop surface 10. The upswept section 20 includes a gasket groove 22, as illustrated in
The gasket 24 includes a rigid section 26 and a flexible section 28. The gasket 24 can be formed by co-extrusion of a rigid material and a flexible material. Given that the gasket 24 is used on a cooking appliance 2 adjacent to and in contact with a cooking surface 10, the rigid material and the flexible material should be able to withstand high temperatures, especially the flexible material as the flexible section 28 will contact the top surface 30 of the cooktop surface 10.
For example, the flexible material should be able to withstand a temperature of at least 80° C. In the illustrated embodiment, the rigid material is a thermoplastic elastomer with a first shore hardness, while the flexible material is also a thermoplastic elastomer with a second shore hardness that is lower than the first shore hardness.
The rigid section 26 of gasket 24 has a tab section 31 that is received within the gasket groove 22, as illustrated in
The rigid section 26 also includes sections 60 and 54 that will be generally parallel to the top surface 30 of the cooktop surface 10 when the gasket 24 is installed into the gasket groove 22.
The flexible section 28 includes a side section 62 and a bottom section 34. The lower surface 66 of the bottom section 34 contacts the top surface 30 of the cooktop surface 10. The length of the side section 62 can be increased or decreased to vary the gap 64 between section 54 of the rigid section 26 and the bottom section 34 of the flexible section 32. In addition, the flexible section 32 can compress against the upswept section 20 and/or the top surface 30 of the cooktop surface 10 to provide a seal between the upswept section 20 and the cooktop surface 10 despite a variation in gaps between the upswept section 20 and the top surface 30. The gap 64 illustrated in
The front terminal end 68 of the bottom section 34 is illustrated as not extending to the front edge 70 of the rigid section 26. This permits the front edge 70 of the rigid section 26 to protect the front terminal end 68 of the flexible section 28 from damage by objects on cooktop surface 10.
The gasket 24 has a generally reversed S-shape cross-sectional profile when installed in the gasket groove 22. The gasket 24 shown in
The invention disclosed herein is further summarized in the following paragraphs and is further characterized by combinations of any and all of the various aspects described therein.
