The humidifying component 20 Disposed inside the housing 10, the humidifying component 20 is used to humidify the air flow. In this embodiment, the humidifying component 20 uses a wet curtain structure. The heating device 30 is disposed inside the housing 10 and is used to heat the air flow. The water supply component 40 is connected with the humidification component 20 and provides water to the humidification component 20 . The water supply component 40 includes a heating section 41 located inside the housing 10 , and the heating section 41 is disposed at the position of the heating device 30 .

The humidification process of the humidification electric heater is: dry air enters from the air inlet, passes through the humidification component (wet curtain) with water, and is blown out from the air outlet (the air flow direction of the air is shown in Figure 5) to achieve the purpose of humidification. In order to increase the humidification amount, the humidification electric heater of the present application is equipped with a water supply component for providing water to the humidification component, and adds a heating section. The heating section obtains heat from the heating device to increase the temperature of the water in the water supply component. High, the hot water with increased temperature flows to the wet curtain, which is more conducive to evaporation. The air flow can take away more moisture after passing through the humidification component, thus increasing the humidification amount. Compared with the humidifying electric heater in the prior art, the humidifying electric heater of the present application has a better humidifying effect, and the increased humidification amount directly shortens the humidification time. On the premise of reaching the same ambient humidity, it only needs a lot of time. The short humidification time not only improves the user experience, but also saves electricity. For example, it takes 1 hour for the original humidifying electric heater to reach the environmental humidity value X, but the humidifying electric heater of this application only takes 40 minutes to reach the environmental humidity value X.

As shown in FIGS. 1 to 3 , the heating section 41 is disposed above the heating device 30 . By utilizing the floating characteristics of the warm air flow, the heating section 41 is placed above the heating device 30, which can increase the heating efficiency and effectively increase the water temperature in the water supply component.

It should be noted that the water supply component 40 in this embodiment is a water supply pipe. The water supply component 40 includes multiple sections of pipelines. The water supply component 40 connects the water tank (or water tank) and the wet curtain. The heating section 41 is used by the water supply component 40 to supply water to the wet curtain.

The air outlet 11 is arranged above the heating device 30. Its advantage is that it utilizes the floating characteristics of the warm air flow to cause the warm air flow to flow toward the air outlet 11 on its own. This not only optimizes the air flow and increases its air outlet efficiency, but also Reduce energy consumption and reduce the fan speed.

Referring to Figures 1 and 2, the heating device 30 includes a heating tube 31. The heating tube 31 is used for heating. The heating tube 31 is provided with fins 32 on the outside.

In the direction of the air flow, the humidification component 20, the wind wheel 70, the heating device 30, and the heating section 41 are arranged in sequence. The airflow enters the interior of the casing from the air inlet 12 under the action of the wind wheel 70. It is first humidified by the humidifying component 20 (wet curtain), and then heated by the heating device 30. Warm air with humidified water vapor is blown out from the air outlet 11. . After passing through the heating device 30, the airflow heats the heating section 41 to heat the water in the water supply component 40, thereby heating the water flowing into the wet curtain.

That is to say, the air flow is first heated and then humidified, and finally blown out from the air outlet.

In some embodiments of the present application, in order to improve the heating efficiency of the heating section 41, the material of the heating section 41 is a thermally conductive material. General metal pipes have thermal conductivity, such as copper pipes and stainless steel pipes. In some embodiments of the present application, the heating section 41 is made of other thermally conductive plastic materials.

In this embodiment, the outer diameter of the heating section 41 is equal to the outer diameter of the heating tube 31. The above-mentioned definition of the outer diameter is the same as the definition of the outer diameter of the tube structure in the mechanical field, because the shape of the heating section 41 is the same as the shape of the heating tube 31. Therefore, the outer diameter dimensions of the heating section 41 and the heating pipe 31 are also the same, so that the heating section 41 will not block the wind, ensuring a stable air output of the humidifying electric heater.

After product heating experiments and preliminary simulations, the outer diameter range of the heating section 41 is 9mm-15mm. When the above-mentioned value is selected for the outer diameter range of the heating section 41, the heat absorption efficiency of the heating section 41 is optimal, and the heat absorption efficiency of the heating section 41 can be achieved without affecting the air flow. Under the premise of achieving maximum efficiency heating.

It should be noted that in some embodiments of the present application, the heating effect of the heating section 41 is simply considered to maximize the humidification effect. In the structure of the humidifying electric heater, the outer diameter of the heating section 41 is larger than the outer diameter of the heating tube 31 . diameter, the larger the outer diameter of the heating section 41, the greater the heat exchange area. For example, the outer diameter of the heating section 41 is 10mm, and the outer diameter of the heating tube 31 is 8mm. In this way, the heat exchange efficiency when the airflow passes through the heating section 41 is better, which makes the water temperature of the humidification component 20 higher and the evaporation effect is better, effectively improving the humidification effect of the humidification electric heater.
