At this time, if the air conditioner is turned on, the working efficiency of the air conditioner will decrease, and the load of the fan will increase, resulting in a decrease in its service life.
[0003] When the frontal wind speed reaches 4m / S (level 2 wind) and above, the natural wind can satisfy the heat exchange on the outside of the air conditioner. At this time, the fan can be turned off. At this time, it is necessary to sense the external frontal wind speed to control whether the fan is powered on. , the traditional wind speed sensor is too expensive to be widely used in air conditioning installations

The invention discloses a wind speed sensing device. The wind speed sensing device comprises an outer shell and an inner shell. An opening facing the coming wind is formed in the front side of the outer shell, an ejector rod is arranged on the inner side of the opening in the outer shell, and a windward side capable of transversely moving in the outer shell is arranged at the front end of the ejector rod. The inner shell is fixedly connected to the inner wall of the rear side of the outer shell, a through hole is formed in the front side of the inner shell, and the rear end of the ejector rod penetrates the through hole and extends into the inner shell. A wafer is fixedly connected to the rear end of the ejector rod. The ejector rod is provided with a spring between the windward side and the inner shell in a sleeved manner. The inner wall of the rear side of the inner shell is fixedly connected with a contact matched with the wafer, and the contact is connected with a led out wire. The wind speed sensing device senses the wind speed to drive a draught fan to work or not to work, and the service life of the draught fan is prolonged. A mechanical structure is adopted, reliability is high, and the use cost is low. The wind speed sensing device is small in size, low in weight, convenient to install, simple in structure, easy to manufacture, safe and reliable.
Description
technical field [0001] The invention relates to the field of refrigeration and air conditioning, in particular to a wind speed sensing device. Background technique [0002] As the urban floor rises, the cross wind received by the outdoor unit of the air-conditioning device placed outdoors increases, and when the wind direction is opposite to that of the air-conditioning outlet, the fan will be pushed to reverse. At this time, if the air conditioner is turned on, the working efficiency of the air conditioner will decrease, and at the same time, the load of the fan will increase, resulting in a decrease in its service life. [0003] When the frontal wind speed reaches 4m / S (level 2 wind) and above, the natural wind can satisfy the heat exchange on the outside of the air conditioner. At this time, the fan can be turned off. At this time, it is necessary to sense the external frontal wind speed to control whether the fan is powered on. , the price of the traditional wind speed ...
