Detailed Description

Fig. 1A is a schematic physical diagram of an air outlet net according to an embodiment of the present invention; fig. 1B is a schematic line drawing of an air outlet net according to an embodiment of the present invention; FIG. 2 is a schematic diagram of a parameter for labeling an air outlet according to an embodiment of the present invention;

as shown in fig. 1A and 1B, an embodiment of the present invention provides an air outlet net, which includes a plurality of ribs 12 arranged horizontally side by side, at least one of the two adjacent ribs 12 has an arched structure, an air outlet 11 is enclosed between the arched structure and the adjacent rib 12 of the rib 12 where the arched structure is located, and an included angle is formed between an air outlet direction of the air outlet 11 and a normal direction of a plane where the air outlet net 1 is located as a whole. The outlet air guide is the direction of the warm air when the warm air is sent out from the air outlet hole 11; the plane of the whole air outlet net 1 is as follows: when the air outlet net 1 is placed on a horizontal desktop, the whole air outlet net 1 is positioned on a surface parallel to the desktop.

The air outlet net 1 is arranged at the air outlet of the electric heater, so that the protection effect can be achieved, and the influence on the normal use of the electric heater caused by the fact that some smaller objects fall into the electric heater can be avoided; meanwhile, the air outlet net 1 also has a certain decoration and covering effect, so that the whole product is attractive. The air outlet net 1 provided by the embodiment of the invention has the two functions, and simultaneously has the function of changing the outlet wind direction of the warm air by changing the structure.

Convection warm air is blown to the air outlet 11 from bottom to top, and the air outlet 11 has a guiding function, so that the direction of the warm air blown out from the air outlet 11 can be changed (the convection warm air is blown to the arch structure, and the change direction of the warm air is blown out from the air outlet 11 due to the blocking of the arch structure), and heat is blown out from the lateral direction firstly and then is lifted upwards. The user can directly experience the heat when near the convection electric heater, and then satisfies closely the heating demand, improves the comfort level that the convection electric heater used.

In this embodiment, each rib 12 is provided with a plurality of continuous arch structures; the top of the arch structure is a vertex, and a connection point between two adjacent arch structures on one rib 12 is a midpoint; the top point of any rib 12 is fixedly connected with the middle point of the rib 12 at one side, the middle point of the rib 12 is fixedly connected with the top point of the rib 12 at the other side, and the air outlet 11 is in a diamond shape. By adopting the structure, the mesh number of the air outlet 11 in the unit area is larger, more warm air can be discharged outwards on the premise of realizing the guiding effect, and the heat inside the electric heater can be further prevented from being accumulated.

As a preferred embodiment of this embodiment, the air-out net 1 further includes planar meshes (not shown in the figure), and the air-out direction of the planar meshes is parallel to the normal direction of the plane of the whole air-out net. The plane mesh is similar to the existing common mesh, does not have the guiding function, and the warm air still continues to blow upwards when passing through the plane mesh. By adopting the structure, the warm air can be quickly dispersed into the room, the room is favorably heated quickly, meanwhile, the direct mode of the warm air cannot cause heat accumulation inside the electric heater, and the utilization rate of the heat is higher.

In the embodiment, a plurality of air outlet holes 11 on the air outlet net 1 form a wind guiding area, and a plurality of plane net holes form a wind straight-through area; the air outlet net is rectangular and comprises a plurality of wind guiding areas and wind straight-through areas; the wind guide area and the wind straight-through area are arranged at intervals along the length direction of the wind outlet net 1. The structure enables the air output of the two air outlet modes to be more uniform, and the two functions are more balanced.

In this embodiment, as shown in fig. 2, preferably, the width W of the air outlet 11 is 8-20mm, and the height H is 6-12 mm. The angle of the side air outlet is 40-60 degrees. The air outlet net 1 is a metal net. The air outlet 11 has guiding performance, and in the guiding process, the ribs 12 block the wind power vertically upwards to a certain extent, so that the wind power is changed, therefore, the ribs 12 have limited width, and the width direction of the ribs 12 is parallel to the whole plane of the air outlet net 1. Preferably, W of rib 12₁The width is 1-5 mm. In practical applications, for example, the parameter setting of the air outlet 11 is not reasonable, and a situation of large heat energy loss (internal accumulation) may occur. The above parameter settings are designed to ensure reasonable heat loss, e.g. less than 1K, in this embodiment.

As shown in fig. 3, the present embodiment further provides a convection electric heater, which includes a housing 2, an air outlet is disposed at the top of the housing 2, and an air outlet net in the present embodiment is disposed on the air outlet. When the air-conditioning device is used, the bottom of the shell 2 is an air inlet, the electric heating device is arranged inside the shell 2, and heated air continues to go upwards and is discharged out of the shell 2 through the air outlet. At the air outlet, the direction of the warm air is changed, and the warm air is blown out to the side, so that the requirement of warming a user at a short distance can be met.

In this embodiment, when the convection electric heater has planar meshes and air outlet holes 11, an openable baffle plate can be arranged at the air outlet of the shell 2 below the air outlet net 1; the baffle can block the wind straight-through area and/or the wind guide area. The purpose of setting up the baffle in casing 2 can realize pushing up the function switching between the air-out and the side air-out, even the convection current electric heater can realize solitary top air-out, or solitary side air-out, also can realize pushing up air-out and side air-out simultaneously. The baffle can be the polylith independent setting, can draw in one side of casing 2 during non-use, during the use, corresponds the below of removing (can set up the track on the casing 2) to corresponding mesh with corresponding baffle, reaches the purpose of sheltering from.

The above detailed description does not limit the scope of the present invention. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions can occur, depending on design requirements and other factors. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
