Abstract
The utility model relates to a cold and warm fan which comprises a fan motor and a fan shroud, wherein the drive shaft of the fan motor extends into the fan shroud and is connected with a fan blade. A porous ceramic carrier which is formed by integral forming is arranged between the fan motor and the fan blade, the porous ceramic carrier is provided with a plurality of penetrating through holes and the surface of the through holes is provided with an electrothermal filming layer which is used for heating. Cold air brough in by the fan is heated when the cold air passes through the through holes with the electrothermal filming layer, then the cold air is blown out by the fan and the utility model has the efficacy of rapid heat circulation. A cylindrical shape is formed at the junction of a partition wall of the through holes in order to eliminate acute angles of the through holes, reduce stress, avoid breaking of the partition wall at the junction and extend the service life. The utility model has simple structure and high safety.
Description
Technical field
The utility model relates to the air conditioner technical field, is meant a kind of cold-warm fan especially.
Background technique
Traditional electric fan mainly includes fan motor and fan shroud, the fan motor transmission shaft extends in the fan shroud, and the drive fan blade is rotated, being designed to and vacillating now to the left, now to the right owing to electric fan, so can make to wave to blow to wind in the angular range at short notice, yet when winter, just no scope for displaying one's abilities for electric fan, also must look for a local collection for it.Though China is cold less than the north southern winter, cold current comes interim, and the southerner who is accustomed to warm weather still is unable to stand, so one to winter, various radiator was kept up a steady flow of.Existing electric heater product, it for example is heating source with the quartz tube, the consumption oxygen because quartz tube can burn, the long-term use in airtight space can be dangerous, and the heat that produced of this kind electric heater just rests on the electric heater periphery and can not circulate, the greenhouse poor effect, the protecting wire net of its front end is because of directly heating temperature is very high, if touch and will be scalded accidentally.A kind of fin type radiator is arranged in addition, it is to circulate in blade with deep fat, contact greenhouse with blade with air, though this kind electric heater does not have the shortcoming of combustion air and scald, yet because the area of contact of blade and air is limited, the heat of its generation just rests on the peripheral not circulation of electric heater, greenhouse poor effect.A kind of PTC ceramic electrical warmer is arranged again, though there is not above shortcoming, the ptc material costliness makes price high.The electric heater that a kind of external form exactly likes electric fan appears again in the market now, promptly replace fan with halogen lamp, also has wiggly structure, yet be positioned at the protecting wire net of halogen lamp front end, closely direct irradiation because of halogen lamp, the high temperature that produces will cause the scald accident as if touching accidentally, and the technological deficiency that this kind relates to personal safety is a great problem that has in this technology to be solved.
Summary of the invention
The purpose of this utility model is to provide a kind of cold-warm fan, by the scheme that manufactures and designs of industrial ceramics product, to remedy the deficiencies in the prior art.
The cold-warm fan that the utility model relates to, it includes fan motor and fan shroud, described fan motor transmission shaft extends in the fan shroud, and be connected with fan blade, be provided with cellular ceramic substrate between described fan motor and the fan blade, this cellular ceramic substrate is one of the forming, and which is provided with the through hole that several run through, and through-hole surfaces has the electric heating coating; Described electric heating coating is as heating source, makes the cool air of being brought into by fan, and the through hole through being provided with the electric heating coating and being heated blows out heated warm sky by fan again.
Described cellular ceramic substrate central authorities are provided with a penetration hole, and the transmission shaft of described fan motor passes from penetration hole, and fan shroud and cellular ceramic substrate are provided with the corresponding part, position and are provided with fixed base with fixing carrying cellular ceramic substrate.
Described fan motor rear end is provided with auxiliary blower.
The partition wall confluce that described carrier forms through hole is set as cylindric.
The utility model cold-warm fan good effect is: owing to adopted present design, the electric heating coating need not be done the conduction heat of secondary in use, thereby has heating fast, evenly, safety, oxygen in the combustion air not, and the advantage that the thermal efficiency is high, and fan itself can about the automatic suitable angle of rotation, diffuse in the room on a large scale in the space thereby can rapidly warm air be blowed, has thermal cycle effect fast, forming through hole partition wall confluce by cellular ceramic substrate is set as cylindric, can avoid the confluce fracture of partition wall, to prolong normal working life, the utility model is simple in structure, safe and reliable, easy to utilize.

Embodiment
As shown in Figure 1, the cold-warm fan that the utility model relates to, it includes fan motor 1 and fan shroud 2, and transmission shaft 10 extensions of described fan motor 1 are arranged in the fan shroud 2, and be connected with fan blade 3, between fan motor 1 and fan blade 3, be provided with cellular ceramic substrate 4;
As shown in Figure 2, cellular ceramic substrate 4, be one of the forming (for example: with the mould extruding and moulding) is provided with several through holes that runs through 40 on cellular ceramic substrate 4, and described cellular ceramic substrate 4 can be designed to suitably profile such as square or circle;
As shown in Figure 3, its through-hole surfaces is provided with electric heating coating 41, and (electrothermal film material adopts resistance material mostly, as: tin, nickel-chromium alloy, copper-nickel alloy, copper-nickel-manganese alloy etc., the mode that forms electric heating coating 41 on its through hole 40 is the thermal chemical reaction method), described electric heating coating 41 is as heating source, the cool air that to be brought into by fan blade 3 is heated through the through hole 40 of electric heating coating 41, blows out the suitable setting temperature hot air that has heated by fan blade 3 again.Because electric heating coating 41 need not be done the conduction heat of secondary in use, thereby have heating fast, evenly, safety, not combustion air and the high advantage of the thermal efficiency, and the design of fan itself can about the automatically design of the suitable angle of rotation, diffuse in the room on a large scale in the space thereby can rapidly warm air be blowed, have thermal cycle effect fast.Described cellular ceramic substrate 4 central authorities have a penetration hole 42 so that transmission shaft 10 is passed, and described fan shroud 2 is provided with the corresponding part, position at cellular ceramic substrate 4 and is provided with fixed base 20 with fixing carrying cellular ceramic substrate 4.
Described fan motor 1 rear end can be provided with auxiliary blower 11, and under the effect of auxiliary blower 11, auxiliary blower blade 3 is sent into outside air, and can cooling fan motor 1.
Described cellular ceramic substrate 4 forms the partition wall 43 of through holes 40, and it is cylindric 44 that its confluce system is set as, and to eliminate the acute angle of through hole 40, so in use, can reduce stress, can avoid the confluce fracture of partition wall 43.(as shown in Figure 4, existing cellular ceramic substrate 5 causes through hole acute angle 52 owing to form the confluce of the partition wall 51 of through hole 50, this through hole acute angle 52 when carrier uses since the air-flow body pass through to produce stress, often appear at the facts generation of rupturing at the acute angle place).
