Example Embodiment

[0037] Example 1

[0038] This embodiment provides an air inlet grill, such as figure 1 , figure 2 with Figure 5 As shown, it includes: a shell, including a top shell 1, a bottom shell 2, and a side shell 3 connecting the top shell 1 and the bottom shell 2 at the same time; one of the side shells 3 is provided with a side air inlet 31, The bottom shell 2 is provided with a bottom air inlet 21.

[0039] In this embodiment, when the electric heater starts to work, the heating device heats the air inside the air inlet grille. The density of the hot air decreases and it moves upward. The cold air below will come in from the bottom air inlet 21 and the side air inlet 31 to supplement , The horizontal and vertical winds gather in the air inlet grille, and then flow out from the top shell 1 of the air inlet grille for heating. Compared with the traditional single top air inlet method, the present invention also adopts The side air inlet 31 and the bottom air inlet 21 increase the air ...

Example Embodiment

[0055] Example 2

[0056] This embodiment provides an electric heating device, including: the air inlet grill provided in embodiment 1; and a heating element 6, such as Figure 4 with Figure 5 As shown, it is arranged inside the air inlet grill.

[0057] In this embodiment, the type of the heating element 6 is not excessively limited, and it may be electric heating, oil heating, etc., as long as it can generate heating.

[0058] As a preferred embodiment, the side air inlet 31 on the side shell 3 is provided at a position below the heating element 6, so that the cold air flowing in through the side air inlet 31 directly rises and acts on the heating element 6 for heat exchange.

[0059] Specifically, the heating element 6 itself is fixed on the side wall of the air inlet grille by screws.

Abstract

The invention provides an air inlet grid and an electric heating device, and belongs to the field of heaters. One of side shells is provided with a side air inlet, and a bottom air inlet is formed ina bottom shell; and when the electric heating device starts to work, a heating device heats air inside the air inlet grid, the heated air density becomes smaller, the heated air moves upwards, cold air below comes in for supplement from the bottom air inlet and the side air inlet, and the air in the horizontal and vertical directions gathers in the air inlet grid, and then flows out of a top shellof the air inlet grid for warming people. Compared to the traditional independent air inlet mode from a top air inlet, the air inlet grid adopts the side air inlet and the bottom air inlet at the same time, so that the air inlet area is expanded, meanwhile, the air is inlet from the side air inlet and the bottom air inlet, the inclined air outlet can be generated, and the inclined air outlet canbetter improve the warming experience.

Description

technical field [0001] The invention relates to the technical field of electric heating devices, in particular to an electric heating device with better heating effect. Background technique [0002] In some cold areas in winter, electric heating devices are needed for auxiliary heating. Common electric heating devices in the prior art include fast heating furnaces, fan heaters, and the like. With the gradual development of electric heating devices, baseboard electric heaters have emerged as the times require. The baseboard electric heaters themselves can be used by hanging on the wall or directly on the inside of the window. It occupies less space, so it is welcomed by the majority of users. [0003] The baseboard electric heater in the prior art is generally short in stature itself, and an air inlet grille is arranged on the outside of the baseboard electric heater, and an air inlet is arranged at the bottom of the air inlet grille, and the cold air passes through the air...
