Abstract

An appliance assembly includes an appliance and a thermal assembly. The thermal assembly includes a housing attached to the appliance, a temperature sensing device carried by the housing and electrically coupled with the appliance, and a thermal fuse carried by the housing and electrically coupled with the appliance, the thermal assembly being a modular assembly and thereby configured for being, as a single unit, attached to and detached from the appliance.

Claims

1. An appliance assembly, comprising:

an appliance; and

a thermal assembly including;

a housing attached to said appliance;

a temperature sensing device carried by said housing and electrically coupled with said appliance; and

a thermal fuse carried by said housing and electrically coupled with said appliance, said thermal assembly being a modular assembly and thereby configured for being, as a single unit, attached to and detached from said appliance.

2. The appliance assembly of claim 1, wherein said thermal assembly includes a plurality of electrical terminals carried by said housing, said plurality of electrical terminals coupled with said appliance.

3. The appliance assembly of claim 1, wherein said temperature sensing device is one of a thermistor, a thermostat, and a thermocouple.

4. The appliance assembly of claim 1, wherein said appliance includes a heater, said temperature sensing device and said thermal fuse being mounted to said housing in close proximity relative to one another such that said thermal fuse detects heat about said temperature sensing device.

5. The appliance assembly of claim 4, wherein said temperature sensing device and said thermal fuse are located within said housing.

6. The appliance assembly of claim 5, wherein said housing includes a cover and a platform, said temperature sensing device and said thermal fuse being mounted on said platform under said cover.

7. The appliance assembly of claim 6, wherein said appliance is a laundry dryer.

8. A thermal assembly, comprising:

a housing configured for coupling with an appliance;

a temperature sensing device carried by said housing and configured for electrically coupling with said appliance; and

a thermal fuse carried by said housing and configured for electrically coupling with said appliance, the thermal assembly being a modular assembly and thereby configured for being, as a single unit, attached to and detached from said appliance.

9. The thermal assembly of claim 8, further including a plurality of electrical terminals carried by said housing, said plurality of electrical terminals configured for coupling with said appliance.

10. The thermal assembly of claim 8, wherein said temperature sensing device is one of a thermistor, a thermostat, and a thermocouple.

11. The thermal assembly of claim 8, wherein said temperature sensing device and said thermal fuse are mounted to said housing in close proximity relative to one another such that said thermal fuse detects heat about said temperature sensing device.

12. The thermal assembly of claim 11, wherein said temperature sensing device and said thermal fuse are located within said housing.

13. The thermal assembly of claim 12, wherein said housing includes a cover and a platform, said temperature sensing device and said thermal fuse being mounted on said platform under said cover.

14. A method of monitoring heat produced by a heater of an appliance, said method comprising the steps of:

providing a thermal assembly including a housing, a temperature sensing device carried by said housing, and a thermal fuse carried by said housing;

attaching said thermal assembly, as a single unit, to the appliance;

electrically coupling said temperature sensing device and said thermal fuse with the appliance;

cutting off the heat produced by the heater using said thermal assembly; and

detaching said thermal assembly, as said single unit, from the appliance, said thermal assembly being a modular assembly.

15. The method of claim 14, further including the step of providing a plurality of electrical terminals carried by said housing, said plurality of electrical terminals coupled with the appliance.

16. The method of claim 14, wherein said temperature sensing device is one of a thermistor, a thermostat, and a thermocouple.

17. The method of claim 14, wherein said temperature sensing device and said thermal fuse are mounted to said housing in close proximity relative to one another such that said thermal fuse detects heat about said temperature sensing device.

18. The method of claim 17, wherein said temperature sensing device and said thermal fuse are located within said housing.

19. The appliance assembly of claim 18, wherein said housing includes a cover and a platform, said temperature sensing device and said thermal fuse being mounted on said platform under said cover.
