More preferably, as shown in fig. 2, the air outlet baffle 14 is located above the heating assembly 20, and the air outlet baffle 14 is disposed above the heating assembly 20 to further facilitate heating of the air outlet baffle 14 in consideration of the rising effect and the heat radiation effect of the hot air.

As shown in fig. 1, in the solution of the present embodiment, a main air outlet 15 is provided at the top of the main casing 10, the heating air outlet 11 constitutes a part of the main air outlet 15, and the humidifying air outlet 13 constitutes another part of the main air outlet 15. The structural design of main air outlet 15 lets the wholeness of electric heater better.

As an alternative embodiment, the heating space a and the humidifying space b are arranged side by side in the horizontal direction, so that the influence of the humidifying assembly 30 on the heating assembly 20 can be avoided to the maximum extent.

Preferably, in the technical solution of this embodiment, the heating air return opening is located at the bottom of the heating space a, and the heating air outlet 11 is located at the top of the heating space a. In this way, the heating space a can be made to have a chimney effect, which is helpful for realizing self-circulation flow of air.

As an alternative embodiment, as shown in fig. 2, the humidifying air return opening 12 is located at the side of the humidifying space b, and the humidifying air outlet opening 13 is located at the top of the humidifying space b. As shown in fig. 3, since the heating space a occupies a larger proportion, the humidifying air return opening 12 is arranged at the side of the humidifying space b, which can ensure a larger air inlet area and is helpful for humidifying air.

As shown in fig. 3, in the solution of the present embodiment, the heating element 20 is an electric heating element. As other alternative embodiments, the heating assembly 20 may also be heated by a refrigeration device.

Wherein, the wind power component 31 is installed between the humidifying air return opening 12 and the humidifying air outlet 13. The humidifying component is installed between the humidifying air return opening 12 and the humidifying air outlet 13. In use, the wind power component 31 is used to generate an airflow between the humidifying air return 12 and the humidifying air outlet 13, and the humidifying component is used to humidify the airflow. Optionally, the wind power component 31 is composed of a motor and an axial flow wind wheel.

As an optional implementation manner, in the technical solution of the present embodiment, the humidifying component includes a wet curtain 32, a water tank 33, a water pump 34 and a water pipe 35. Wherein, wet curtain 32 is installed between humidification return air inlet 12 and humidification air outlet 13, and water tank 33 is used for storing water and adding water to wet curtain 32, and water tank 33 is installed in the below of wet curtain 32, and water pump 34 passes through water pipe 35 and connects between water tank 33 and wet curtain 32.

After being energized, the heating assembly 20 heats up and the motor and water pump 34 operate simultaneously. The water pump 34 transfers the water in the water tank 33 to the wet curtain 32 through the water pipe 35, then flows to the wet curtain 32, wets the whole wet curtain 32 from top to bottom, and flows back to the water tank 33 through the overflow hole of the wet curtain 32 after the wet curtain 32 is saturated by water. After the wind wheel rotates, air enters from the outer side of the wet curtain 32, and dry air passes through the wet curtain 32 and becomes wet air. After the heating assembly 20 generates heat, the hot air rises, and due to the installation of the air outlet baffle 14, the humid cold air cannot be directly mixed with the hot air generated by the heating assembly 20, and the temperature of the air outlet cannot be reduced. After the whole machine is operated, the humidification is realized while heating, so that the whole temperature and humidity in a room reach an ideal state. When a single function is needed, the heating function or the humidifying function can be turned off through the controller, so that the whole machine only has the humidifying or heating function.

The material of the support of heating element 20 is high temperature resistant insulating material, and air-out baffle 14 is installed between the sheet metal component.

As shown in FIG. 5, when the water tank 33 is empty, the water filling opening can be opened by pressing the water filling cover 333 on the upper cover of the water tank 33, and water can be filled from the water filling opening, after the water filling is completed, the water filling cover 333 is pressed back to the original position, and after the cover is in place, obvious pause feeling can be generated, and the user can know that the water filling cover is in place. The water tank 33 is provided with a water supply hole 331 connected to the water pipe 35 and an overflow hole 332 for receiving excess water supply.

As shown in fig. 2, in the technical solution of this embodiment, the arc of the shape of the air outlet baffle 14 is 4 to 6 ° so as to facilitate the guiding out of the humidified air flow. More preferably, the arc of the air outlet baffle 14 is 5 °.

Preferably, in the technical solution of this embodiment, the bottom end of the air-out baffle 14 is lower than the bottom end of the humidifying air-return opening 12. This ensures that the outlet baffle 14 guides all the air entering from the humidifying air return opening 12.

As another alternative embodiment not shown in the drawings, a vent hole is provided at the upper part of the air outlet baffle 14, and the vent hole is used for letting the airflow in the humidifying space b to enter the heating space a to be mixed with the airflow in the heating space a. Thus, a part of the wet air flow coming out of the humidifying space b can be blown to the heating space a through the vent holes, mixed with the heated air flow and blown out through the upper heating air outlet 11, and another part of the wet air flow coming out of the humidifying space b is blown out through the humidifying air outlet 13.
