Motor driving system, variable frequency air conditioner and using method of variable frequency air conditioner

Abstract

The invention discloses a motor driving system, a variable frequency air conditioner and a using method of the variable frequency air conditioner. A device adopted in the method comprises a device main body and a variable frequency air conditioner protection device arranged in the device main body, the variable frequency air conditioner protection device comprises a first cavity arranged in the device main body and provided with a leftward opening, a second cavity is arranged in the inner wall of the lower side of the first cavity in a communicating mode, a first lead screw is rotationally arranged in the second cavity, the right end of the first lead screw is rotationally connected to the inner wall of the right side of the second cavity through a bearing, a first sliding block in threaded fit connection with the first lead screw is arranged in the second cavity in a sliding mode, and a third cavity is arranged in the inner wall of the left side of the second cavity. When the air conditioner device is not in use, an air conditioner outdoor unit can be automatically stored in a cavity so as to be protected. When the air conditioner device is in use, the device can automatically send out the air conditioner outdoor unit.

Description

technical field [0001] The invention relates to the technical field of air conditioner auxiliary devices, in particular to a motor drive system, an inverter air conditioner and a use method thereof. Background technique [0002] With the improvement of the quality of life, many families now use air conditioners. Air conditioners include the main unit of the air conditioner installed indoors and the external unit of the air conditioner installed outdoors. Among them, the external unit of the air conditioner is installed outdoors and exposed to the external environment for a long time , it is easy to cause the aging of the outdoor unit of the air conditioner, and at the same time, it is easier to accelerate the aging of the outdoor unit in bad weather, such as rainy days and strong winds, and foreign objects in the outdoors are also easy to enter the machine, causing damage to the machine slot. Therefore, the present invention aims to Design a motor drive system and inverter a...

[0002] With the improvement of the quality of life, many families now use air conditioners. Air conditioners include the main unit of the air conditioner installed indoors and the external unit of the air conditioner installed outdoors. Among them, the external unit of the air conditioner is installed outdoors and exposed to the external environment for a long time , it is easy to cause the aging of the outdoor unit of the air conditioner, and at the same time, it is easier to accelerate the aging of the outdoor unit in bad weather, such as rainy days and strong winds, and foreign objects in the outdoors are also easy to enter the machine, causing damage to the machine slot. Therefore, the present invention aims to Design a motor drive system and inverter air conditioner that can automatically store the external unit of the air conditioner in the chamber to protect it when the air conditioner is not in use, and when in use, the device can automatically send out the external unit of the air conditioner device and how to use it
