Abstract
A heat sink for LEDs or other electronic elements in a kitchen appliance is provided. The chassis or other heat conducting components of the appliance are used as a heat sink to conduct away heat. The LEDs or other electronic features may be connected directly to the heat sink or may be connected by e.g., a bracket.
Description
- The present invention provides a heat sink for LEDs or other electronic elements in a kitchen appliance.
- Modern kitchen appliances are frequently provided with various features that rely upon electronics for operation. For example, a range hood or oven may include a processing device mounted on a printed circuit board (PCB) and connected with a touch panel or other device whereby the user may select various options for operation of the appliance. For an oven, such PCB might include different, user selectable cooking algorithms based on the food and/or mode of cooking desired. The PCB typically associated with such features is electrically-powered and generates heat during operation. If the PCB becomes too hot, the electronics may cease to operate properly or even become permanently damaged.
- Some appliances may also be equipped with lighting features that rely upon light emitting diodes (LEDs) to provide illumination. For example, a range hood or an over the range microwave oven may include various LED bulbs to light up a cook top. Such lighting may be important to the user as the cook top will typically have several heating elements positioned on a horizontal surface for cooking food contained in pots and pans.
- For these applications, LED lighting has certain advantages as compared to incandescent or other types of lights. These advantages can include e.g., resistance to vibration, long life expectancy, relatively low energy use, durability for repeated on-off switching, and compactness. In addition, where more light is needed, LED bulbs can be grouped together to increase the intensity of the light output.
- However, there are certain challenges to using LED lamps in a kitchen appliance. As with a PCB, LED lamps can produce a significant amount of heat and are susceptible to poor operation if their temperature rises too high. More particularly, there is generally a narrow range of temperatures at which LED lamps can efficiently produce their maximum light output or most efficient light output. In addition, if the temperature elevates above a certain range, the LEDs can be damaged or even destroyed.
- As such, an appliance must provide for properly cooling electronics and LED lamps during operation. Such can be a difficult task with a kitchen appliance because of the heat that is generated from cooking. For example, LED lamps are sometimes provided in a range hood to provide lighting above the cook top. Heat coming from the cook top and/or an associated oven will rise up and through the range hood. Depending upon the placement of the LED lamps, this heat can provide further temperature problems for LED lamps by advancing the temperature increase. Similar problems can be created for a PCB or other electronics if positioned where they can be affected by heat from cooking.
- Accordingly, a system for the effective cooling of LED lamps or other electronics in a kitchen appliance would be useful. A system that can use structural and other features of the appliance to facilitate such cooling would be beneficial. Such a system that can be readily incorporated within the overall design of an appliance would also be very useful.

The electronic component is thermally connected with the heat conducting element such that heat generated by the electronic component is conducted to the heat conducting element.

FIG. 1 provides an exemplary embodiment of the present invention as arange hood 10 installed withinkitchen cabinetry 22.Range hood 10 includes auser interface 20 that hasmultiple controls 42 as may be used to activate a fan, lights, or other features.Range hood 10 is positioned over anoven 18 that includes a horizontal, cook-top surface 14 havingmultiple heating elements 16 positioned thereon.Heating elements 16 may be e.g., electrically-powered or gas fueled and provide heat for cooking food placed into pots or pans and positioned ontosuch elements 16.Oven 18 includes a cavity, positioned behinddoor 19, into which food items may be placed for baking and/or broiling. - During operation of
oven 18, heat and cooking fumes are generated fromheating elements 16 and/or the baking or broiling in the cavity. This heat will rise upwardly, towardsrange hood 10. As such, at least some of the heat from cooking operations will heatrange hood 10 and its associated lighting and other electronic features. -
FIG. 2 provides a cross-sectional view ofrange hood 10. For this exemplary embodiment,range hood 10 includes anLED lamp 30 that is operated by one or more of thecontrols 42 positioned onuser interface 20. Wiring 38 connectsLED lamp 30 withcontrol 42. Although only asingle LED lamp 30 is shown, a plurality of LED lamps could be positioned aboutrange hood 10 depending upon the amount of light desired. - In the configuration shown,
LED lamp 30 provides light for the illumination of cook-top surface 14 onrange 12. More specifically,LED lamp 30 provides light through an opening 44 in anupper appearance panel 32. Additional openings can be provided for other LED lamps positioned inrange hood 10 as desired. - A typical LED lamp can provide more light, and is more efficient at producing light, as temperature decreases. During operation of
LED lamp 30, it will generate a significant amount of heat that can be deleterious to its proper functioning. In addition, the heat generated from cooking withoven 18 further exacerbates the problem by providing additional heat that can adversely affectLED lamp 30. - Accordingly,
LED lamp 30 is in thermal contact with a mountingpanel 34, which forms part of the frame orchassis 46 ofrange hood 10. As shown inFIG. 2 ,LED lamp 30 is attached directly topanel 34 and, as such, heat generated bylamp 30 will be conducted topanel 34. In turn, becausepanel 34 is constructed from a conductive material such as a metal, heat will be conducted throughpanel 34 to other parts of thechassis 46 ofrange hood 10 thereby improving its efficiency as a heat sink forlamp 30.Panel 34 is shown as a flat sheet inFIG. 2 . However, other configurations and shapes forpanel 34 may be used as well. In addition,lamp 30 can also be placed on heating conducting elements used to constructrange hood 10. - Mounting
panel 34 is positioned behindupper appearance panel 32. More particularly, with respect to the flow of heat rising upwardly fromoven 18,panel 34 is shielded from such heat byupper appearance panel 32. As such,mount panel 34 is protected from the heat generated by cooking so as to improve its ability to conduct heat away fromLED lamp 30. - In addition,
range hood 10 is constructed in a manner that uses natural convection to help further coolLED lamp 30.Chassis 46 and ventduct 24 form achamber 48. AsLED lamp 30 heats up during operation and, in turn, conducts heat to mountingpanel 34, air withinchamber 48 near the surface of mountingpanel 34 will be heated. The heated air will then rise withinchamber 48 to be displaced by cooler air falling down to replace the heated air. This process of natural convection further contributes to the cooling ofLED lamp 30. - Additionally, the placement of
LED lamp 30 can be controlled to further improve the cooling effects of mounting it topanel 34. More specifically, the placement ofLED lamp 30 alongupper appearance panel 32 can be selected such thatlamp 30 is not directly over a heat source fromoven 18 such as one of theheating elements 16. The size ofrange hood 10, i.e., the extent to whichhood 10 projects out and overappliance 18 can also be increased in order to moveLED lamp 30 further away from a position directly above heat sources inoven 18. -
FIG. 3 provides another exemplary embodiment of arange hood 10 in which like reference numerals to that ofFIG. 2 represent identical or similar features. UnlikeFIG. 2 , however,LED lamp 30 is placed into direct thermal contact or communication withvent duct 24. In the example ofFIG. 3 ,LED lamp 30 is attached directly to the walls formingvent duct 24.Light pipes 36 are used to transmit light produced byLED lamp 30 to theopening 44 inupper appearance panel 32. Light is emitted from theterminal end 40 oflight pipes 36 so as to project light onto cook-top surface 14 (FIG. 1 ).Light pipes 36 are provided by way of example only. Light sheets, fiber optics, and other devices may also be used for transmitting light fromLED lamp 30 towards cook-top surface 14. - By positioning
LED lamp 30 directly into contact withvent duct 24, heat generated during operation oflamp 30 can be conducted directly to ventduct 24. By constructingvent duct 24 from a conductive material such as a metal, heat conducted fromLED lamp 30 is turn conducted alongvent duct 24, which in turn helpscool lamp 30. In addition, during operation ofrange 12, the user may activatefan 26 to draw heat and cooking fumes away fromrange 12 and to an exhaust as shown by arrows A. The movement of air throughvent duct 24 will also helpcool vent duct 24 and improve its efficiency as a heat sink forLED lamp 30. As previously described,chamber 48 will also contribute to the cooling ofLED lamp 30 through natural convection. - The above exemplary embodiments of the present invention were described using
LED lamp 30. As will be understood by one of ordinary skill in the art using the teachings disclosed herein, the same principles can be used to provide for the cooling of a PCB or other electronics that need protection from heat. For example, the PCB could be attached to mountingpanel 34 or other parts of thechassis 46 ofrange hood 10 for the conduction of heat away from the PCB. Similarly, the PCB could be attached to ventduct 24 to conduct heat away from the PCB in a manner as described above with regard toLED lamp 30. With both a PCB orLED lamp 30, it should be understood that such may be directly connected to a heat sink such aschassis 46 as shown inFIGS. 2 and 3 , or a mounting bracket may also be used to connect the PCB orLED lamp 30. In such case, preferably the mounting bracket is also constructed from a conductive material such as a metal so that thermal communication with the heat sink is provided. - As will be understood by one of skill in the art using the teachings herein, the present invention may be used with other appliances as well and is not limited to a range hood. For example, similar constructions may be used to provide cooling for the electronics found in an oven, a microwave mounted over cook-top surface, and still other appliances as well. In addition, the LED or PCB can be connected to other parts of the appliance that can operate as a heat sink, and the present invention is not limited to the configurations shown in the figures. As such, it should be understood that this written description uses examples to disclose the invention, including the best mode, and also to enable any person skilled in the art to practice the invention, including making and using any devices or systems and performing any incorporated methods. The patentable scope of the invention is defined by the claims, and may include other examples that occur to those skilled in the art.
