Abstract
A radiation-convection type electric warmer is characterized by that the most of its casing is covered by an air and heat permeable enclosure, its heat generator assemblage in the casing is composed of parallel and vertical electrothermal units arranged on the supporter of supporter, said electrothermal unit consists of serially connected 4-5 electrothermal plates, its power is controlled by a selection knob, and a switch which can be cut off when the warmer falls to the ground is used for preventing fire accident. Its advantage is high temp raising speed because of direct heat radiation plus air convection.
Description
Technical field
The present invention relates to a kind of warmer, a kind of electric radiation convection warmer of more specifically saying so.
Background technology
As existing warmer is many is the oil medium type space heater that a kind of vertical inside has Circulation and Hot Oil Spray to dispel the heat by fin, and the heat of deep fat is kept with gradient of temperature and then depended on power output to the heating of its power supply.The shortcoming of above-mentioned this oil medium type warmer is the circulation that temperature rise is slow, the built-in oil pump of needs is kept deep fat, and power consumption is big, and the thermal efficiency is low, and its fatal weakness just is that intensification is too slow, and power consumption is big, therefore not too gets consumer reception.
Summary of the invention
The solution of the present invention be a kind of main by thermal-radiating form for people's heating, and be aided with convection action whole room air warmed rapidly, both realized that radiation among a small circle directly warms oneself, realize the warmer of the indoor intensification in space on a large scale again.It includes the casing that most front covers on every side are transmissive heat and air, described casing is the square or rectangular cube shape of flat type substantially, the face that seals of this cube transmissive heat can be six faces, also can be five or four and seal face that the described face that seals can adopt metallic sieve manufacturing.Certainly, also can adopt other heat-resisting thermal conductivity good, diathermanous but plate material air proof makes, such effect is compared with the scheme that adopts metallic sieve can be weaker, because cross-ventilation can be obstructed.
Be equipped with on the footing of described casing and can make the convenient roller that moves of complete machine, the scheme of not adorning roller certainly also is feasible, but effect also can be weaker.The roller of being adorned can be four, also can be two.The material of described casing is a heat resistant plastice, also can use metal material.Described casing is that the unit block by the manufacturing of polylith apportion is assembled into one.
End face and a side elevation (narrow) intermediate location at described casing are provided with a dual-purpose oblique teat branch, and it both had been used as the gauge tap panel, can be used as again hand in hand.Be provided with a open-work in the edge that described oblique teat divides for holds.The end face of described oblique teat is provided with power switch and electrical power conversion knob, preferably also will be provided with timer, radiator valve, power supply indicator.In described casing, also be provided with a tumbler switch that prevents that fire from taking place.Described tumbler switch can adopt mercoid switch, and what the present invention adopted is a weight strut type tumbler switch.The depression bar that it includes switch case, flexibly connects with the housing end face, on the free end of described depression bar, be fixed with a weight, described depression bar is all the time towards the spring button of the described housing end face of lower compression under the effect of weight, at this moment, dynamic and static contact in the tumbler switch housing is in closure state all the time, and entire circuit is in the state of " leading to ".When space heater is gone over accidentally, described weight strut type tumbler switch becomes the flat state that crouches by erectility, the spring button of described tumbler switch housing end face is owing to lost the compressing of weight depression bar at this moment, be in the free state that projects upwards, dynamic and static contact is in released state, and entire circuit then is in " opening circuit " state.Described tumbler switch is installed in the outer lower portion of described heating element assembly bracket side frame or directly is fixed on the bottom surface of casing.
Heater element assembly in the casing of space heater of the present invention includes the support that fixes with casing, described support further comprises two side frames, be fixed with two fixing shelves of electric hot plate up and down betwixt, on described upper and lower fixing shelves, be even interval shape and fixing the electric hot plate that the 4-10 piece is parallel to each other, after can polylith being connected into a unit, plurality of units is in parallel again, conversion by power selector switch realizes all energisings simultaneously of the energising of a certain unit or all unit, to realize the different conversions of using between the power.The described electric hot plate of each piece is the filled board of " sandwich " formula, placed in the middle is by the plane of nickel one chromium heating wire through bending process one-tenth, in its both sides the mica sheet double team is arranged, described heating wire is to get on by the mica sheet that a kind of heat-resisting glue is bonded to both sides.Certainly, other resistant to elevated temperatures insulation sheet material also is to can be used to replace the mica sheet material.After the sandwich electric hot plate of " sandwich " formula forms, again it is inlayed upper enclosure frame (frame), thereby form complete electric hot plate.Heater element assembly scheme best in the casing of space heater of the present invention includes nine blocks of such electric hot plates, and they are uniform interval and are fixed on the described support.Wherein four blocks of electric hot plates are concatenated into a first module, and other five blocks of electric hot plates polyphone becomes one second unit, and these two unit are together in parallel again, are connected in the circuit by a power selection knob.On described support, on upper and lower fixing shelves, there is resistant to elevated temperatures insulation gap piece that each piece electric hot plate is spaced from each other.The open-work that passes for described fixing shelves is arranged, the hole that the contact lead of powering in addition passes on every block of electric hot plate.The layout of the electric hot plate in the described heater element assembly can also be other form except mutual vertical parallel is arranged, and for example is the arrangement mode of the complications extension of indention.The shape of its every electromotive force hot plate also can not be tabular but the curved surface shaped of circular arc.
At least comprising the series circuit that fuse, temperature controller, power selection rotary switch, heater element assembly constituted in the warmer circuit of the present invention is the most basic circuit part.In order to make function perfect more, in described basic series circuit, also can be connected in series timer, temperature guarantor's switch and the anti-tumbler switch that catches fire.
Compared with prior art, the invention has the advantages that thermal efficiency height, temperature rise speed is fast, security good, conveniently moving, outward appearance novelty, existing effect of closely directly warming oneself among a small circle, utilize the cross-ventilation temperature of the interior large space scope of conditioning chamber rapidly in addition, the effect that room temperature is risen rapidly.
