Abstract
The invention discloses an air outlet grid for a convection heater. The air outlet grid comprises a grid plate (1); the grid plate (1) is provided with a plurality of elongated air outlet holes (2) at intervals; a first turned edge (21) and a second turned edge (22) are formed on two sides of the air outlet holes (2) respectively; all the first turned edges (21) and the second turned edges (22) face the interior of the convection heater; and the tail edges of the first turned edge (21) and the second turned edge (22) of each air outlet hole (2) close to the tail edges of the second turned edge (22) and the first turned edge (21) of the adjacent air outlet hole (2). Compared with the prior art, the air outlet grid has the advantages that the peripheral temperature of an air outlet accords with the related test standard and is easier to reach the standard, and better air outlet and air supply effects of an electric warming oven can be achieved.
Description
Technical field
The present invention relates to the technical field of warmer, relate in particular to a kind of outlet grid that is used for the convection type warmer.
Background technology
Household warming in the market, mainly comprise electric heating installation using oil as medium and PTC the pottery warm-air drier, wherein, the advantage of electric heating installation using oil as medium is the flames of anger, removable, shortcoming be preheating time long, power consumption is big, heating effect is not obvious.The advantage of PTC warm-air drier is not need preheating, forced convertion, and shortcoming is that air quantity is little, power consumption is big, is only applicable to 15 square metres of little spaces once.The PTC warm-air drier is one or more PTC heat-generating pipes are installed in device and are constituted the heating part, the heat that distributes by heater element reaches heating effect, be generally the heat energy Fast Heating ambient air that heater element is distributed, air blast also is housed in many warm-air driers the heat that heater element produces is produced by boasting from hot-air mouth, with the circumference air.This shows, need to adopt the air blast blowing, can make heater element not reach desirable heating temp, energy consumption is also higher, and air blast can only blow out hot blast from a face, and heating effect is not good enough.
Thereby, many employing cross-ventilations and reach the convection type warmer utilization of heating purpose and give birth to, as the patent No. is the Chinese utility model patent " no fin convection type electric heating device " of ZL91221038.9 (notification number is CN2106978Y), and for example the patent No. is the Chinese utility model patent " convection type warmer " of ZL94212197.X (notification number is CN2209292Y), and the patent No. is the Chinese utility model patent " cross-ventilation formula space heater " of ZL200520067239.7 (notification number is CN2835883Y) for another example.In many convection type warmers, its air outlet all needs to be provided with the outlet grid of band exhaust vent, such as, in " no fin convection type electric heating device " scheme, at its air outlet place woven wire is set and as outlet grid, in the scheme of " cross-ventilation formula space heater ", the outlet grid at its air outlet place is exactly a grid that offers platoon leader's bar shaped exhaust vent.
Yet, aspect the manufacturing industry of warmer, peripheral temperature for numerous space heater, all be provided with relevant criterion, (generally adopting 60335-1 and two kinds of testing standards of 60335-2-30 of warmer manufacture view at present) generally can not be higher than 155 degrees centigrade, the overheated just easy user that scalds, have potential safety hazard, be unfavorable for safe handling.If outlet grid simply adopts woven wire by above-mentioned patented technology, woven wire can generate heat immediately during actual the use, then very easily take place to scald unexpected, and it is up to standard to adopt common outlet grid, the temperature on its outlet grid surface also to be difficult for, and all requires further improvement.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of outlet grid that is used for the convection type warmer at above-mentioned prior art present situation, it can make the peripheral temperature of air outlet meet the dependence test standard, be easier to up to standardly, and make electric heater air-out air-supply effect better.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: this is used for the outlet grid of convection type warmer, comprise screen, the exhaust vent that has the strip of a plurality of intervals setting on the screen, it is characterized in that: the dual-side of exhaust vent forms first flange, second flange respectively, the direction of all first flange, second flange is all towards the inside of convection type warmer, and the last limit of first flange of each exhaust vent, second flange is drawn close with second flange of adjacent exhaust vent, the last limit of first flange respectively.
Also promptly, first flange, the relative screen of second flange top layer are obliquely installed, thereby form the stop part that one group of trap heat directly contacts with the screen top layer at the back side of screen.
For avoiding conducting to the top layer of screen to greatest extent from the heat that send warmer inside, preferably, first flange of each exhaust vent and the distal edge of second flange are along offseting with second flange of adjacent exhaust vent, the distal edge edge of first flange respectively, also be, and make two adjacent flange form the structure of triangular-section, so, the hot gas that flows out from the warmer air outlet is fully stopped by first flange, second flange, and can not touch the grid of screen, the temperature on screen top layer can be effectively controlled, it is very high can not become, and is easier to up to standard.
For making this outlet grid can be convenient to fix with the shell of warmer, the both sides of described screen can form upper and lower flanging to back side direction, all have on the flanging in order to fixing hole clipping.
Compared with prior art, the invention has the advantages that: by flange being set in exhaust vent both sides arranged side by side, make adjacent two flange form an energy in order to the hot-air that intercepts warmer inside directly with exhaust vent between the stop part that contacts of grid, also be, a plurality of first flange, second flange cooperate, form the stop part that a trap heat conducts to outlet grid, very effective, the grid temperatures that can effectively avoid outlet grid is too high and scald the user, make the peripheral temperature of air outlet meet the dependence test standard, and make electric heater air-out air-supply effect better.
