Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Structure of the present utility model sees that accompanying drawing 1 is to shown in Figure 4.A kind of cold-warm fan, comprise equipped mutually body 1, electric machine assembly 3 and front mesh enclosure assembly 4, body 1 has front panel 1a, indent circle 1b and rear net cover 1c, front panel 1a has control switch, body 1 indent circle 1b circle mouth is fitted with heater 2, for reducing cost, available heater 2 is conductive rubber or conductive plastic or ceramet, and is separated to form the galvanic circle through isolation layer.This heater 2 leads to lead 5, and this lead 5 is electrically connected the control switch that is positioned at body 1 front panel 1a; This heater 2 has heating inner ring 2c, along outward extending at least three the heating supporting frame 2b of the heating equal radian of inner ring 2c periphery, and is somebody's turn to do the heating outer ring 2a that heating supporting frame 2b supports; Make and processing for convenient, circle extends to the outside convex body that forms in heating outer ring along portion for the heating supporting frame, and this convex body is through insulation thermal-protective coating apical grafting body indent circle.Further, circle is shaped on insulated thermal insulating layer along portion's 2d periphery, in order to cooperate the circle mouth of body indent circle, to prevent that the heater temperature conduction is to body.
Also can be chosen in heating outer ring 2a periphery and be shaped on circle along the circle mouth of the 2d of portion in order to cooperation body 1 indent circle 1b; For conveniently connecting, also can select to enclose along the 2d of portion is that thread groove or bayonet socket thread groove or bayonet socket corresponding and that the circle mouth of body 1 indent circle 1b is shaped on match.
For increasing the thermal efficiency of heater, heater 2 also has at least one circle heating centre circle 2e, and this heating centre circle 2e is at heating inner ring 2c and generate heat between the 2a of outer ring and bridging heating supporting frame 2b.Heating inner ring 2c suit electric machine assembly 3; There is one to be shaped on hollow cavity among the heating supporting frame 2b, in order to run through the circuit that is electrically connected electric machine assembly 3.For further increasing the thermal efficiency of heater, heating centre circle 2e has along the inwardly outer raised line that extends of periphery.For effectively protecting motor and making its proper functioning, electric machine assembly 3 comprises insulation crust 3a, motor 3b and fan blade 3c, and heating inner ring 2c suit is with the insulation crust 3a of motor 3b.
Conductive rubber progressively is applied on the heating new product as the heating new material.During the conductive rubber energising, the electric current maximum that begins to flow through, the power maximum of consumption, along with the conductive rubber temperature rises, electric current and power and temperature are inversely proportional to, when temperature rises to 57 when spending, electric current and power all make zero, and continue to rise to 72 degree and are tending towards constant until temperature.Constant temperature product with this made has good Security, the flames of anger and can initiation fire, and softness can fold arbitrarily.
Conductive plastic is as " high-quality tetrafluoro conductive plastic film ", the planar electric heating of this material tool, electromagnetic shielding, excellent specific properties such as the accurate resistance of high stable, radioresistance, ageing-resistant, soft folding can be widely used in the heating below 200 ℃, insulation, oven dry, protection, elements such as resistance.Use easyly, with low cost, light weight is reliable, and is safe and power saving.
Ceramet is as a kind of novel thermosensitive resistance material, and it has characteristics such as temperature-sensitive, time-delay, current limliting and constant temperature.Be used as heater, have life-span length, safety, the flames of anger, intensification rapidly, be subjected to advantages such as the current/voltage influence of fluctuations is minimum, be the desirable substitute products of resistance wire and electric heating tube, be widely used in the various heaters, as be applied to fields such as air conditioner, warm-air drier, clothes drier.
Working principle: when definite temperature is opened and set to heater 2 control switchs, heater 2 is promptly connected the power supply heating power, motor 3b control switch is opened to connect and is started, the wind-force that fan blade 3c produces brushes the heat of heater 2 generations and forms hot blast, this mobile hot blast room temperature that can raise realizes the function of warm braw fan; And when cutting off heater 2 control switchs, heater 2 is that the deenergization energising is not generated heat, and then can be used as the common electrical fan and uses.So, the use of can rotating in two seasons of summer in winter has the using effect of saving cost and parking space, and can arbitrarily move according to the needs that use.
Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
