Description

A kind of double fan blade humidification heater

technical field

The invention relates to the technical field of air conditioning, in particular to a dual-blade humidification heater.

Background technique

In cold winters, especially in areas without heating, many people choose to use electric heaters for indoor heating, but the use of heaters will inevitably cause the indoor humidity to decrease and the air to dry, which will cause long-term exposure to such an environment. Human discomfort; especially the heater, because it has a fan to force hot air convection, which will aggravate indoor drying;

At present, there are some natural convection heaters in the world that use an open water box outside the body, and use the heating temperature of the heater to evaporate the water to humidify the room, but the evaporation of water in this way is small, and the humidification effect is not ideal;

Chinese patent document CN 107621060 A adopts the method of adding a heating tube in the body, and a water tank is arranged on the body. After the heating tube heats the water, water vapor is brought out into the air for humidification. This form not only has a complex structure, high noise, and high cost High temperature, and high water vapor temperature, there is a danger of scalding, and there are potential safety hazards; if an independent humidifier is used to humidify, it will increase the user's cost of use, and it is not energy-saving and environmentally friendly;

In addition, a humidifier wet pad carrier is arranged in the air passage between the air inlet and outlet of the heater, and when the air flows through the wet pad carrier, the moisture on the upper part is taken away to humidify the air; At the same time, it will flow through the surface of the motor or the heating body of the fan, such as the Chinese patent document CN207050106 U, which also has potential safety hazards and affects its service life.
