Abstract

Some embodiments of the present disclosure provide an electric heater, which includes: a housing provided with an air inlet and an air outlet, and the housing internally having an air duct communicated between the air inlet and the air outlet; and a heating member and a convection member both being assembled in the air duct, wherein the heating member being configured for heating the air entering from the air inlet to the air duct during energization, the convection member being configured for blowing a heated air from the air duct to the air outlet for discharging. Herein the air outlet is provided on a bottom end of the housing close to a ground.

First claim

What is claimed is:

1. An electric heater, comprising:
a housing, the housing being provided with an air inlet and an air outlet, and the housing internally having an air duct communicated between the air inlet and the air outlet;
a heating member and a convection member, both being assembled in the air duct, the heating member being configured for heating the air entering from the air inlet to the air duct during energization, the convection member being configured for blowing a heated air from the air duct to the air outlet for discharging,
wherein the air outlet is provided on a bottom end of the housing close to a ground;
wherein, in a direction of gravity, the convection member is disposed lower than a position of the heating member;
wherein the air duct comprises an air inlet duct and an air outlet duct which are communicated up and down, and the air inlet duct is communicated with the air inlet, and the air outlet duct is communicated with the air outlet,
wherein the heating member is disposed in the air inlet duct, and the convection member is disposed in the air outlet duct;
wherein there is a distance between a top end of the heating member and a top wall of the housing;
the electric heater further comprises an air deflector disposed in the air inlet duct, two ends of the air deflector are respectively connected with a bottom end of the heating member and an inner wall of the housing, and the heating member and the air deflector divide the air inlet duct to form a first sub-air inlet duct and a second sub-air inlet duct which are communicated to each other,
wherein, the sub-air inlet duct is communicated with the air inlet, and the second sub-air inlet duct is communicated between the first sub-air inlet duct and the air outlet duct.

2. The electric heater according to claim 1 , wherein the housing comprises a bottom surface, a top surface, and a side surface connected between the top surface and the bottom surface, and the bottom surface and an end of the side surface connected with the bottom surface serve as the bottom end of the housing.

3. The electric heater according to claim 2 , wherein the air outlet is provided at the end, connected with the bottom surface, of the side surface of the housing, and the air inlet is provided at an end, connected with the top surface, of the side surface of the housing and the top surface of the housing.

4. The electric heater according to claim 2 , wherein the air outlet is provided at one end, connected with the bottom surface, of the side surface of the housing, and the air inlet is provided at one end, connected with the top surface, of the side surface of the housing or the top surface of the housing.

5. The electric heater according to claim 1 , wherein the heating member comprises an electric heating film heating member; wherein the air inlet is at least partially used as a heat radiating port.

6. The electric heater according to claim 5 , wherein the heating member is directly faced to the heat radiating port.

7. The electric heater according to claim 5 , wherein the housing comprises a body and a radiation grid, wherein the radiation grid is assembled on the body, and the heat radiating port is formed on the radiation grid.

8. The electric heater according to claim 1 , wherein the housing comprises a body and an air outlet grid, wherein the air outlet grid is assembled on the body, and the air outlet is formed on the air outlet grid.

9. The electric heater according to claim 1 , wherein the electric heater further comprises a volute casing and a volute tongue disposed in the air outlet duct, and the volute tongue is stretched into the volute casing, the volute tongue, the volute casing and the inner wall of the housing form an air outlet space, the air inlet duct and the air outlet are communicated by the air outlet space,
wherein the convection member is disposed in the air outlet space.

10. The electric heater according to claim 1 , wherein the convection member is a cross-flow fan, and the cross-flow fan is disposed in the air duct along a horizontal direction.
