Humidifier

Abstract

The invention aims to provide a humidifier with low working noise and a large vapor diffusion area. The humidifier comprises a case on which a water storing cavity, an air inlet and an air outlet are formed, wherein the air inlet and the air outlet are communicated through an air channel which is provided with a fan; an ultrasonic atomization device and a heating and vaporizing device are arranged in the case; the heating and vaporizing device consists of a heating water tank, a vaporizing cavity which is formed above the liquid level of the heating water tank, and an electric heating element; the ultrasonic atomization device consists of an ultrasonic water tank, an ultrasonic generating device and an atomization cavity which is formed above the liquid level of the ultrasonic water tank; the heating water tank and the ultrasonic water tank are communicated with the water storing cavity through the water channel; and the atomization cavity and the vaporizing cavity which serve as a part of the air channel are connected in series with the air channel. Provided with the ultrasonic atomization device and the heating and vaporizing device simultaneously, the humidifier works more quietly due to the unique air channel, the vapor diffusion area is enlarged under the condition of the same energy consumption, the practicability of the humidifier is improved, and requirements of customers are met.

Description

technical field [0001] The invention belongs to the technical field of household appliances, and in particular relates to a humidifier. Background technique [0002] A humidifier is a household appliance used to adjust the indoor air humidity. It mainly includes an ultrasonic humidifier and a heating humidifier. It is transformed into ultrafine particles and negative oxygen ions of 1-5 microns, and diffuses the water mist into the air through the wind device, making the air moist and accompanied by abundant negative oxygen ions; the working principle of the heating humidifier is to put water in the electric The heating body is heated at a high temperature to generate steam, which is directly distributed into the air or sent out by a fan to achieve the purpose of humidifying the air. [0003] The ultrasonic humidifier has low noise and large amount of atomization during operation, but due to the large water molecule particles of the water mist, the temperature of the mist g...

AI Technical Summary

Problems solved by technology

[0003] The ultrasonic humidifier has low noise and large amount of atomization during operation, but due to the large water molecule particles of the water mist, the temperature of the mist generated is low and the diffusion range is small, and because of the long-term humid environment in the humidifier, it is easy to Breeding bacteria, polluting the indoor environment; the water vapor produced by the heating humidifier is small, the water vapor temperature is high, and the diffusion range is large, but when it is working, it will generate a lot of noise due to the boiling of water, giving The environment produces noise pollution, and the power consumption is large, and the use cost is high

Chinese patent document CN 200920194006.1 discloses an air humidifier that assembles an ultrasonic humidifier and a heating humidifier on the same body, and mixes the two types of mist in the mixing chamber at the outlet to increase the amount of atomization, although to a certain extent The atomization temperature is increased, the diffusion range is increased, and it also has a certain bactericidal effect; but there are still insufficient mixing and insignificant bactericidal effects, especially the defect of large noise caused by water boiling during heating, which still pollutes the indoor environment
