Problems solved by technology

[0004] However, the start-up current at the moment when the infrared lamp is turned on is relatively large, and frequently starting the infrared lamp will shorten the service life of the infrared lamp
Since the infrared lamp is a pure resistive load, its cold-state resistance is low, and the starting current of the infrared lamp is relatively large when it is powered on (for example, the starting current of a 1.5KW infrared lamp is as high as 40A-50A, and the normal operating c

Description

technical field [0001] Embodiments of the present invention relate to air-conditioning appliances, in particular to an infrared humidifier. Background technique [0002] The infrared humidifier can quickly evaporate the water in the water tank without boiling, and produce clean steam for air humidification. [0003] Existing infrared humidifiers all have high-power infrared lamps inside, and the infrared lamps will emit high heat after being energized, and use these heat to evaporate the water in the water tank into water vapor, thereby achieving the purpose of humidification. The control method is as follows: when the humidity sensor detects that the indoor humidity is low, the infrared lamp is turned on at full load; when the humidity reaches the set value, the infrared lamp is turned off; Turn on the infrared lamp at full load, and turn off the infrared lamp after the humidity reaches the set value, so as to achieve indoor humidity control. [0004] However, the start-u...
