What is claimed is:
1. A damper apparatus for a microwave oven, comprising:
an air duct for guiding a cooling air from a machinery compartment of said microwave oven into an oven cavity;
a damper rotatably installed in said air duct, for opening or closing the flow of air in the air duct; and
a motor which includes a shaft directly connected to said damper to thereby drive the damper.
2. The apparatus of claim 1, further comprising a micro switch, installed at one side of said air duct, for detecting the opening and closing states of the damper by contacting one side of the damper.
3. The apparatus of claim 2, wherein said micro switch detects a closing state of the air duct when said damper is contacted to the micro switch and an opening state of the air duct when the damper is separated from the micro switch.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An apparatus for dispensing a two-part adhesive comprising:
a first collapsible bag containing a first part of the two-part adhesive;
a second collapsible bag containing a second part of the two-part adhesive; and
a manifold that communicates with the first collapsible bag and the second collapsible bag, the manifold including a first projection device that pierces the first collapsible bag and a second projection device that pierces the second collapsible bag,
wherein each part flows from its respective collapsible bag into the manifold after the bag is pierced and wherein the manifold directs each part of the two-part adhesive separately through the manifold and out of an exit of the manifold.
2. The apparatus of claim 1 wherein the two parts of the two-part adhesive exits the manifold in about a 1:1 ratio.
3. The apparatus of claim 1 wherein the two parts of the two-part adhesive exits the manifold in a ratio where one part exceeds the other part.
4. The apparatus of claim 1 further comprising a nozzle that is coupled to the exit of the manifold.
5. The apparatus of claim 4 wherein the nozzle mixes the two parts together into a mixture that is ejected from the nozzle as the adhesive.
6. The apparatus of claim 5 wherein the nozzle 36 element mixing nozzle.
7. The apparatus of claim 4 wherein the manifold and the nozzle are a single unit.
8. The apparatus of claim 1 wherein each bag is made of a polyester film.
9. The apparatus of claim 8 wherein the polyester film is a biaxially-oriented polyethylene terephthalate.
10. The apparatus of claim 1 wherein the manifold is made of plastic.
11. The apparatus of claim 1 wherein the manifold is made of aluminum.
12. The apparatus of claim 1 further comprising a first member in which the first bag is positioned and a second member in which the second bag is positioned, each of the first and second members being coupled to the manifold.
13. The apparatus of claim 12 further comprising a first connector that couples the first member to the manifold and a second connector that couples the second member to the manifold, wherein the first projection device is located in the first connector and the second projection device is located in the second connector.
14. The apparatus of claim 12 wherein each of the first and second members are cylinders.
15. The apparatus of claim 12 wherein each of the first and second bags are compressed with a respective mechanism that applies a pressure to the bag to eject the first and second parts out of the respective bags.
16. The apparatus of claim 15 wherein the mechanism is a rack and pinion mechanism or a chain a sprocket mechanism.
17. An apparatus for dispensing a two-part adhesive comprising:
a first member that holds a first collapsible bag containing a first part of the two-part adhesive;
a second member that holds a second collapsible bag containing a second part of the two-part adhesive;
a manifold that is coupled to the first member and the second member and that communicates with the first collapsible bag and the second collapsible bag, the manifold including a first projection device that pierces the first collapsible bag and a second projection device that pierces the second collapsible bag,
wherein each part flows from its respective collapsible bag into the manifold after the bag is pierced and wherein the manifold directs each part of the two-part adhesive separately through the manifold and out of an exit of the manifold.
18. The apparatus of claim 17 further comprising a nozzle that is coupled to the exit of the manifold.
19. The apparatus of claim 18 wherein the nozzle mixes the two parts together into a mixture that is ejected from the nozzle as the adhesive.
20. The apparatus of claim 17 wherein each bag is made of a polyester film.
21. The apparatus of claim 17 further comprising a first connector that couples the first member to the manifold and a second connector that couples the second member to the manifold, wherein the first projection device is located in the first connector and the second projection device is located in the second connector.
22. The apparatus of claim 17 wherein each of the first and second members are cylinders.
23. The apparatus of claim 17 wherein each of the first and second bags are compressed with a respective mechanism that applies a pressure to the bag to eject the first and second parts out of the respective bags into the manifold.
24. The apparatus of claim 23 wherein the mechanism is a rack and pinion mechanism or a chain a sprocket mechanism.
