Power saving device for starting a rotor using a mainspring

Abstract

To cut down electric power when starting a rotation body (e.g., an outdoor unit fan of an air conditioner) by a spiral spring.SOLUTION: There is provided a power saving device used when starting a rotation body by a spiral spring. When power is turned ON, a rotor (2) for starting enters a space between a rotor (3) for winding a spiral spring and a rotation body (1), and the rotation body (1) is moved from a resting state by the release force of the spiral spring (4) directly connected to the rotor (3) for winding a spiral spring. At this moment, the rotation body (1) is not electrified yet. When the spiral spring is released, the rotor (2) for starting is separated from between the rotor (3) for winding a spiral spring and the rotation body (1), the rotation body (1) is electrified, and brought into a normal operation state. In this manner, electric power when starting the rotation body is cut down. When the power is turned OFF, the rotor (3) for winding a spiral spring comes in direct contact with the rotation body (1) so that the spiral spring is wound using idling energy of the rotation body.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to a rotating body such as an outdoor fan of an air conditioner. [Background technology]

[0002] Conventionally, a rotating body is started by energizing it, which requires a large amount of energy, but there has been no invention related to saving this energy. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Published Patent Publication (A) Patent Application 2012-123673 (P2012-123673) Summary of the Invention [Problem to be solved by the invention]

[0004] Rotating objects such as air conditioner outdoor unit fans require a large amount of energy (mainly electricity) to start up from a stopped state. This is because, due to the laws of motion (laws of inertia), a large amount of force is required to move a heavy stationary object. This invention aims to cut power consumption at start-up by starting rotating bodies such as the outdoor fan of an air conditioner from a stationary state with a spring, thereby saving energy. The spring is released at start-up, but is wound up by the idling energy when the rotating body is stopped, so no extra force is required. [Means for solving the problem]

[0005] The rotating body (mainly the outdoor unit fan of an air conditioner) (1) is normally not in contact with anything, as in the past. When the power is turned on, the starter rotor (2) enters between the spring winding rotor (3) and the rotating body (1), and the releasing force of the spring (4) starts the rotating body (1) moving from a stationary state. At this time, no electricity is passed through the rotating body (1), saving energy. In other words, even if you press the power ON button on the air conditioner remote control, no electricity is passed through the rotating body of the outdoor unit; instead, the spring is simply released by the force of the energized electromagnet. The starting rotor (2) is directly connected to the mainspring (4) and is attached to a movable arm so that its position can be changed. The winding rotor (3) is also attached to a movable arm so that its position can be changed. Once the spring has been released, the arm to which the starting rotor (2) is attached is moved away from between the spring winding rotor (3) and the rotor (1), and electricity is applied to the rotor (1) to return to normal operation. At this point, the rotor (1) is already in an idling state due to the release force of the spring, so no extra power is required. When the power is off, the arm to which the winding rotor (3) is attached is moved to directly contact the rotating body (1), and the idling energy of the rotating body is used to wind the mainspring. Once the winding of the mainspring is complete, the starting rotor (2) is inserted (the arm is moved) between the winding rotor (3) and the rotating body (1) to prepare for the next start-up. Then, starting by the mainspring is resumed. This is a power saving device when a rotating body is started by a mainspring. Effect of the Invention

[0006] Conventionally, a large amount of energy was required to start up a rotating body, but the present invention cuts this amount of energy, contributing to energy conservation. [Brief description of the drawings]

[0008] Hereinafter, an embodiment of the present invention will be described. The rotating body (mainly the outdoor unit fan of an air conditioner) (1) is normally not in contact with anything, as in the past. When the power is ON (when the power is ON on the air conditioner remote control), the starter rotor (2) is placed between the mainspring winding rotor (3) and the rotating body (1), and the rotating body (1) starts moving from a stationary state by the release force of the mainspring (4) that is directly connected to the mainspring winding rotor (3). At this time, no electricity is passed through the rotating body (1), saving energy. In other words, even if you press the power ON button on the air conditioner remote control, no electricity is passed through the rotating body of the outdoor unit; instead, the mainspring is simply released by the force of the energized electromagnet. The starting rotor (2) is directly connected to the mainspring (4) and is attached to a movable arm so that its position can be changed. The winding rotor (3) is also attached to a movable arm so that its position can be changed. One end of each rotor is a fulcrum and the other end is an electromagnetic switch that can change its position. Once the spring has been released, the arm to which the starting rotor (2) is attached is moved away from between the spring winding rotor (3) and the rotor (1), and electricity is applied to the rotor (1) to return to normal operation. At this time, the rotor (1) is already in an idling state due to the release force of the spring, so no large amount of energy is required. When the power is off, the arm to which the winding rotor (3) is attached is moved to directly contact the rotating body (1), and the idling energy of the rotating body is used to wind the spring. Once the winding of the spring is complete, the arm is moved to place the starting rotor (2) between the winding rotor (3) and the rotating body (1), preparing for the next start-up. The next time the power is turned on, the spring will start up again. This is a power saving device when a rotating body is started by a mainspring. [Explanation of symbols]

Claims

[Claim 1] The rotating body (1) in the outdoor unit fan of an air conditioner is not in contact with either the starting rotor (2) or the spring winding rotor (3) before the power is turned on, and when the power is turned on, the starting rotor (2) enters between the spring winding rotor (3) and the rotating body (1), and the rotating body (1) is moved from a stationary state by the release force of the spring (4) directly connected to the spring winding rotor (3). At this time, no current is applied to the rotating body (1), saving energy, the spring winding rotor (3) and the spring (4) are attached to a movable arm so that their positions can be changed, and the starting rotor (2) is also attached to a movable arm so that its position can be changed, and the spring After the spring has been released, the start rotor (2) is removed from between the spring winding rotor (3) and the rotating body (1), and electricity is passed through the rotating body (1) to enter a normal operating state. At this time, the rotating body (1) is already in an idling state due to the release force of the spring, so no extra power is required. When the power is turned off, the spring winding rotor (3) comes into direct contact with the rotating body (1), thereby winding the spring by utilizing the idling energy of the rotating body. After the spring has been wound up, the start rotor (2) is inserted between the spring winding rotor (3) and the rotating body (1) to prepare for the next start-up. When the power is turned on, the start rotor (2) resumes start-up by the spring. This is a power saving device for starting a rotating body by a spring.
