Description

Technical Field

[0001] The invention belongs to the technical field of household appliances, and particularly relates to a fog-free humidifier. Background Art

[0002] In the prior art, a humidifier is a household appliance that increases the humidity in a room. Currently, the household humidifier market is primarily divided into ultrasonic humidifiers and thermal evaporative humidifiers. Ultrasonic humidifiers use high-frequency ultrasonic oscillations to break up water into mist particles, which are then introduced into the indoor air via a fan and other components to achieve humidification. These ultrasonic humidifiers produce a large amount of visible mist during operation, which can cause surrounding surfaces to become foggy or even wet. Thermal evaporative humidifiers use electrical heating to vaporize water, much like the way wind dries wet clothes. These humidifiers are the safest, most effective, energy-efficient, environmentally friendly, and high-capacity humidification method, making them extremely popular in the market. They significantly humidify dry indoor air in northern China, significantly increasing indoor comfort and contributing to improved quality of life. Consequently, market demand for mistless humidifiers is growing. However, due to the immaturity of existing thermal evaporative humidifiers, their penetration rate is relatively low, necessitating further improvements to existing thermal evaporative humidifiers.

[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0032] See also Figures 1-10 The mistless humidifier involved in this embodiment includes:

[0033] Vaporization water tank A is used to store a fixed amount of water and provide space for the vaporization of the water;

[0034] The water membrane component B is used to continuously adsorb and vaporize the water in the water tank A to continuously generate a water film;

[0035] Hot air component C, used to generate hot air to heat and vaporize the water on the water film;

[0036] The water film assembly B is movably mounted within the vaporizing water tank A. The air inlet of the hot air assembly C is connected to the air inlet 701 at the bottom of the humidifier body, while the air outlet of the hot air assembly C is connected to the air inlet of the vaporizing water tank A. The air outlet of the vaporizing water tank A is connected to the mist outlet structure on the humidifier body. The water film assembly B and the hot air assembly C are electrically connected to the main control board 16 on the humidifier body. In this mistless humidifier, by placing the water film assembly B within the vaporizing water tank A and at least partially immersing it in water, combined with the movement of the water film assembly B, a water film continuously forms on the surface of the water film assembly B. The hot air generated by the hot air assembly C heats and vaporizes the water on the water film, thereby continuously generating steam for humidifying the indoor air. This achieves effective mistless humidification, high humidification capacity, and a healthy and hygienic appearance.

[0037] Furthermore, the mistless humidifier also includes a water storage tank D for storing water; the water path of the water storage tank D is connected to the vaporization tank A to supply water to the vaporization tank A; the water path between the water storage tank D and the vaporization tank A is provided with a filter component E for filtering the water, a pump body 11 for providing water pressure, and a sterilization module 10 for sterilizing and purifying the water. Specifically, the humidifier body is provided with a detachable water storage tank 2, the top opening of the water storage tank 2 is exposed at the top of the humidifier body, and the opening at the top of the water storage tank 2 is provided with a water tank cover 1. The water storage tank D is the inner cavity of the water storage tank 2, and the filter component E is detachably arranged at the bottom of the inner cavity of the water storage tank 2; in the vaporization water tank A, if the water level is too high, the part of the water membrane component B immersed in water will increase and the part used for heating and vaporization will decrease. If the water level is too low, the part of the water membrane component B immersed in water will decrease and the part used for heating and vaporization will increase. Regardless of whether the water level is too high or too low, the imbalance between the immersed part and the heated vaporization part will directly affect the amount of steam generated. For this reason, it is necessary to accurately control the water level height in the vaporization water tank A, which results in the vaporization water tank A not being able to store too much water. For this reason, the vaporization water tank A is replenished with water in time by setting the water storage tank D; in addition, in order to ensure the water quality, a filter component E and a sterilization module 10 are provided in the water supply water path.

A water film layer 15 wraps around the side wall of the rotating bracket 14 and covers the air outlet structure 1403. Hot air enters the vaporization air duct 1402 through the air inlet structure 1401 and then reaches the air outlet structure 1403.
