Abstract

The utility model relates to a grating structure of a warm air outlet of a warmer, which comprises a grating frame provided with a plurality of lattice bars in the middle part, wherein the cross section of the lattice bar comprises an inside air inlet segment and an outside air outlet segment, the width of the lattice bar of the air outlet segment is larger than that of the lattice bar of the air inlet segment, and the lattice bar segments with different widths at both sides form smooth transition; the end part of the air inlet segment of the lattice bar is provided with a full fillet for reducing windage resistance, the inside air inlet segment is in a shape with equivalent width, an equilateral triangle extended outwards is formed on the outside air outlet segment and forms the smooth transition with the inside equivalent width air inlet segment. The utility model has the characteristics of simple structure, convenient use, not easy deformation of the lattice bar, long service life and the like.

Description

A kind of cell structure of warmer warm braw outlet

Technical field

The utility model relates to a kind of cell structure in the outlet of convection type warmer warm braw, and the mounting structure of this grid and panel, ceiling type indoor heater technical field belonged to.

Background technology

Traditional warmer warm braw outlet cell structure, as shown in Figure 1, it includes the grill frame 12 that an intermediate configurations has many glazing bars 11, it includes the glazing bar made from aluminium section bar 11, the thickness of this glazing bar has certain requirement, and because of tool thickness even, thereby easily thermal deformation, length can not be oversize; Described glazing bar 11 also has made of plastic, and because of it is injection molded, so its thickness must be more than 2mm, and must have reinforcement, not only outward appearance is ugly, also can fall alkali under the effect because of long term thermal, and is aging fast; Also have with direct punching structure on the aluminium alloy panel, from the thin portion of part as can be seen, this structure not only stops wind action, but also can cause inner warm too high generation potential safety hazard because bounce-back hinders the speed of normal wind field.

In a word, in the warmer field, ceiling type convective warmer warm braw outlet grid exists following defective always:

First because the convection type warmer must shed heat by wind action, and this just has certain requirement to the hear resistance of air port material, the normal at present high-temperature resistance plastice PPS that adopts, but outward appearance technology is poor, and grid thickness is big, not only severe noise, the easy deformation in addition of producing of choke; Also have a kind of application aluminium or steel wire as the air port, flexible after the aluminium thin slice is heated, steel wire outward appearance class is very low, and needs to electroplate back use, defect rate height through spot welding;

The second ceiling type convective warmer in use must fully shed built-in temperature, otherwise the too high meeting of internal temperature causes potential safety hazard, this just requires very high to the warmer windage, the people is in using the warmer process in addition, apart from the ceiling type warmer certain distance is arranged, in order to reach good heating effect, then the wind speed of warmer must be very big, sound again must be very little simultaneously, and traditional ceiling type warmer is difficult to do until what time to be taken into account;

Summary of the invention

The purpose of this utility model is to overcome the deficiency that prior art exists, and provide a kind of simple in structure, easy to use, glazing bar is not yielding, long service life, the cell structure of the warmer warm braw outlet of defectives such as the outward appearance that the fine solution prior art of energy exists, windage, noise, wind speed.

The purpose of this utility model is finished by following technical solution, it includes the grill frame that an intermediate configurations has many glazing bars, the cross section of described glazing bar comprises the inboard wind inlet section and the wind outlet section in the outside, and the glazing bar width of described wind outlet section is greater than the glazing bar width of wind inlet section, and both sides do not wait the glazing bar section of width to be formed with rounding off.

The end of the wind inlet section of described glazing bar is set to reduce the perigon angle of windage effect, and inboard wind inlet section is wide shape, and is formed with the equilateral triangle shape that extends out at described outside wind outlet section, and forms described rounding off with the wide wind inlet section of inboard.

The utility model adopts special aluminium alloy extrusions, novel cross section appearance, do at the air intake place of glazing bar very thin (0.7～0.8mm) and perigon angle handle and the broad of doing at the wind outlet of glazing bar (3.0mm), between carry out level and smooth excessively, thereby reach required result of use.This cell structure has not only increased rigidity, makes it to be difficult for flexural deformation, and air outlet is had the effect of an acceleration, also has the incrustation beauty function, and it has simple in structure, and is easy to use, and glazing bar is not yielding, characteristics such as long service life.

Description of drawings

Fig. 1 is the prior art constructions schematic diagram.

Fig. 2 is the novel structural representation of this reality.

Fig. 3 is the B-B generalized section of Fig. 2.

Fig. 4 is the local enlarged diagram of the D among Fig. 3.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in detail: shown in Fig. 2-4, the utility model includes the grill frame 22 that an intermediate configurations has many glazing bars 21, the cross section of described glazing bar 21 comprises the inboard wind inlet section 23 and the wind outlet section 24 in the outside, and the glazing bar width of described wind outlet section 24 is greater than the glazing bar width of wind inlet section 23, and both sides are not waited between the glazing bar section of width and are formed with rounding off 25.

The end of the wind inlet section 23 of described glazing bar 21 is set to reduce the perigon angle 26 of windage effect, inboard wind inlet section 23 is wide shape, and be formed with the equilateral triangle shape 27 that extends out, and form described rounding off with the wide wind inlet section 23 of inboard at described outside wind outlet section 24.

From the D partial enlarged drawing of Fig. 4 as can be seen, the structure of novel glazing bar 21 can increase its wind speed at the A place because of the effect of damming, from the B schematic diagram as can be seen, because of the tool arc structure, play nature wind-guiding function, effectively reduce sound of the wind, from shown in the schematic diagram, this structure air intake place is little in addition, and the bottom is big, and (top is 0.8mm, the bottom is the most surperficial to be that 3mm is wide), outward appearance has been promoted certain level.

Shown in the figure is buckle shape steam air heater panel, and wherein grill frame 22 is fixedly installed to the centre of buckle face, and forever one is fixing also can be detachably fixedly connected, to constitute panel warm wind port 28 and cross-ventilation air inlet 29 as shown in Figure 2.Other embodiment of the present utility model also can be used for the panel of warm-air drier separately, or on the panel of multifunctional heater; Also can be used on the independent or multi-functional ventilator.
