Abstract
Official abstract text for this publication.
A compressor includes a casing having a cylindrical portion, a compression mechanism fixed to an inner peripheral surface of the cylindrical portion, an external portion, a weld nut, and a bolt. The external portion includes a temperature reaction portion that reacts to a temperature change of the cylindrical portion. The external portion is mounted on an outer peripheral surface of the cylindrical portion. The weld nut is welded to the outer peripheral surface of the cylindrical portion to mount the external portion on the outer peripheral surface of the cylindrical portion. The bolt fixes the external portion to the weld nut.

What is claimed is: 1. A method of manufacturing a compressor that includes a casing having a cylindrical portion and including a top portion and a bottom portion located at ends of the cylindrical portion, a compression mechanism fixed to an inner peripheral surface of the cylindrical portion; an external temperature sensor including a temperature reaction portion that reacts to a temperature change of the cylindrical portion, the external temperature sensor being mounted on an outer peripheral surface of the cylindrical portion; a weld nut welded to the outer peripheral surface of the cylindrical portion to mount the external temperature sensor on the outer peripheral surface of the cylindrical portion; and a bolt that fixes the external temperature sensor to the weld nut, the method comprising: a first step of welding the weld nut to the outer peripheral surface of the cylindrical portion; a second step of welding the compression mechanism to the inner peripheral surface of the cylindrical portion; a third step of welding the top portion and the bottom portion of the casing to the cylindrical portion; and a fourth step of mounting the external temperature sensor on the outer peripheral surface of the cylindrical portion, the compressor being manufactured in order of the first step, the second step, the third step, and the fourth step. 2. A compressor comprising: a casing having a cylindrical portion, an external temperature sensor including a sensor portion and a mounting portion, the sensor portion measuring a temperature of the cylindrical portion and the mounting portion being mounted on the cylindrical portion and pressing the sensor portion so that the sensor portion is in close contact with an outer peripheral surface of the cylindrical portion; a weld nut welded to the outer peripheral surface of the cylindrical portion to mount the mounting portion to the cylindrical portion; and a bolt that fixes the mounting portion to the weld nut. 3. The compressor according to claim 2 , wherein a plurality of the weld nuts is arranged along a first direction, and the first direction is an axial direction of the cylindrical portion. 4. The compressor according to claim 3 , wherein a position of the sensor portion along the first direction falls within a range of a fixing portion along the first direction, and the fixing portion fixes the compression mechanism to the cylindrical portion. 5. The compressor according to claim 3 , wherein the weld nut is welded to the outer peripheral surface of the cylindrical portion by projection welding or spot welding. 6. The compressor according to claim 3 , wherein the weld nut is welded to the outer peripheral surface of the cylindrical portion by projection welding. 7. The compressor according to claim 3 , wherein the mounting portion includes an attaching bracket and an attaching spring, and the attaching bracket brings the sensor portion into close contact with the cylindrical portion. 8. The compressor according to claim 3 , wherein the sensor portion further includes a temperature reaction portion and an elastic heat transfer sheet mounted between the temperature reaction portion and the cylindrical portion. 9. The compressor according to claim 3 , wherein the sensor portion includes a temperature reaction portion, the cylindrical portion has an outer diameter ranging from 80 mm to 160 mm, and a length of the temperature reaction portion along a circumferential direction of the cylindrical portion ranges from 10 mm to 20 mm. 10. The compressor according to claim 2 , wherein the weld nut is welded to the outer peripheral surface of the cylindrical portion by projection welding or spot welding. 11. The compressor according to claim 10 , wherein the mounting portion includes an attaching bracket and an attaching spring, and the attaching bracket brings the sensor portion into close contact with the cylindrical portion. 12. The compressor according to claim 10 , wherein the sensor portion further includes a temperature reaction portion and an elastic heat transfer sheet mounted between the temperature reaction portion and the cylindrical portion. 13. The compressor according to claim 10 , wherein the sensor portion includes a temperature reaction portion, the cylindrical portion has an outer diameter ranging from 80 mm to 160 mm, and a length of the temperature reaction portion along a circumferential direction of the cylindrical portion ranges from 10 mm to 20 mm. 14. The compressor according to claim 2 , wherein the weld nut is welded to the outer peripheral surface of the cylindrical portion by projection welding. 15. The compressor according to claim 2 , wherein the mounting portion includes an attaching bracket and an attaching spring, and the attaching bracket brings the sensor portion into close contact with the cylindrical portion. 16. The compressor according to claim 15 , wherein the sensor portion further includes a temperature reaction portion and an elastic heat transfer sheet mounted between the temperature reaction portion and the cylindrical portion. 17. The compressor according to claim 15 , wherein the sensor portion includes a temperature reaction portion, the cylindrical portion has an outer diameter ranging from 80 mm to 160 mm, and a length of the temperature reaction portion along a circumferential direction of the cylindrical portion ranges from 10 mm to 20 mm. 18. The compressor according to claim 2 , wherein the sensor portion includes a temperature reaction portion, the cylindrical portion has an outer diameter ranging from 80 mm to 160 mm, and a length of the temperature reaction portion along a circumferential direction of the cylindrical portion ranges from 10 mm to 20 mm. 19. An outdoor unit of an air conditioner comprising: the compressor according to claim 2 . 20. A compressor comprising: a casing having a cylindrical portion; a compression mechanism fixed to an inner peripheral surface of the cylindrical portion; an external temperature sensor including a temperature reaction portion that reacts to a temperature change of the cylindrical portion, the external temperature sensor being mounted on an outer peripheral surface of the cylindrical portion; a weld nut welded to the outer peripheral surface of the cylindrical portion to mount the external temperature sensor on the outer peripheral surface of the cylindrical portion; and a bolt that fixes the external temperature sensor to the weld nut, the external temperature sensor further including an elastic heat transfer sheet mounted between the temperature reaction portion and the cylindrical portion. 21. The compressor according to claim 20 , wherein the cylindrical portion has an outer diameter ranging from 80 mm to 160 mm, and a length of the temperature reaction portion along a circumferential direction of the cylindrical portion ranges from 10 mm to 20 mm. 22.
