Abstract
The utility model provides a structurally improved fan, especially a cooling and warming fan which mainly comprises a fan motor and a fan shroud, wherein a drive shaft of the fan motor extends into the fan shroud and is provided with a fan blade. At least one porous ceramic carrier which is formed by integral forming is arranged between the fan motor and the fan blade, and the porous ceramic carrier is provided with a plurality of penetrating through holes. The carrier can be designed into appropriate external shapes such as a square, a circle, etc. The surface of the through holes is provided with an electrothermal plated film layer which is used for heating. Therefore, rear cold air brought in by the fan blade is heated through passing through the through holes with the electrothermal plated film layer and then the air is blown out through the front end of the fan blade. The utility model has the effect of rapid heat circulation. The partition wall forming the through holes forms a cylindrical shape at a juncture to eliminate acute angles for the through holes and to reduce stress generation, and the utility model achieves the efficacy of preventing the partition wall from breaking at the juncture.
Description
Technical field
The utility model belongs to the cold/hot air-conditioning technical field, is meant a kind of Cold-warm fan of novel structure especially.
Background technique
Traditional electric fan comprises a fan motor and fan shroud, the fan motor transmission shaft extends in the fan shroud, and be provided with fan blade, because electric fan is designed to and can swings, therefore can make in the short time in the pivot angle degree scope and blow to wind, yet when winter, just no scope for displaying one's abilities for electric fan, also is necessary for it and looks for a local collection.Though the winter in Taiwan is cold less than the north, cold current comes interim, and the Taiwanese who is accustomed to warm weather still is unable to stand, and therefore one to winter, various radiators were kept up a steady flow of.Radiator product commonly used is as heating source with quartz tube, the oxygen because quartz tube can burn, the long-time use in airtight space can be dangerous, and the heat that this electric heater produces does not circulate around resting on electric heater, the greenhouse poor effect, the protecting wire net of its front end is because of directly heating temperature is very high, if run into and will be scalded accidentally.Another kind of fin type radiator, be in blade, to circulate with deep fat, contact greenhouse with blade with air, oxygen and easy shortcoming of scalding though this electric heater does not burn, but because the area of contact of blade and air is limited, and the heat that produces does not circulate the greenhouse poor effect around resting on electric heater.Also have a kind of PTC ceramic electrical warmer, though there is not above shortcoming, the ptc material costliness, price is high.A kind of electric heater that exactly likes electric fan appears again now on the market, replace fan with halogen lamp, also have the structure that swings, yet be positioned at the protecting wire net of halogen lamp front end, because of the closely direct irradiation of halogen lamp,, the high temperature of generation will scald if touching accidentally.
The model utility content
The purpose of this utility model be propose a kind ofly to heat fast, evenly, safety, oxygen and the high Cold-warm fan of the thermal efficiency do not burn
The cold-warm fan that the utility model proposes comprises a fan motor and fan shroud, and the transmission shaft of fan motor extends in the fan shroud, and is provided with fan blade.Be provided with at least one cellular ceramic substrate between fan motor and the fan blade, described ceramic monolith is formed in one, have a plurality of through holes that run through above, through-hole surfaces has the electric heating coating, described electric heating coating is used for heating, blow out by the fan blade front end again, have thermal cycle effect fast.
The through hole that described ceramic monolith forms, the partition wall of this carrier formation through hole is set as cylindric in the confluce, to eliminate the through hole acute angle, reduce stress and produce, and avoids the confluce fracture.
The utlity model has heating fast, evenly, safety, not combustion air and the high advantage of the thermal efficiency, and fan itself be designed to can about the automatic suitable angle of rotation, therefore can rapidly warm air be blowed and be diffused in the room on a large scale in the space, have thermal cycle effect fast.

Embodiment
Fig. 1 is this creation embodiment schematic representation, the utility model mainly includes a fan motor (1) and fan shroud (2) as shown in Figure 1, this fan motor (1) transmission shaft (10) extends in the fan shroud (2), and be provided with fan blade (3), the utility model mainly is provided with at least one cellular ceramic substrate (4) between fan motor (1) and fan blade (3), cellular ceramic substrate (4) as shown in Figure 2, this cellular ceramic substrate (4) is formed in one, for example: with the mould extruding and moulding, have a plurality of through holes that run through (40) on it, described cellular ceramic substrate (4) can be designed to suitably profile such as square or circle, to be applicable to installation environment.As Fig. 3, this through-hole surfaces has electric heating coating (41), the electric heating Coating Materials is resistance material commonly used, as: tin, nickel-chromium alloy, copper-nickel alloy, copper-nickel-manganese alloy ... etc., it is the thermal chemical reaction method that described electric heating film goes up the mode that forms electric heating coating (41) at through hole (40), for example: the high temperature atomizing.Described electric heating coating (41) act as heating, the rear cool air of being brought into by fan blade (3) is heated through having the through hole (40) of electric heating coating (41), blow out the suitable setting temperature hot air that has heated by fan blade (3) front end again, because electric heating coating (41) need not be done the biography of secondary in use, heat conduction, thereby has heating fast, evenly, safety, the high advantage of the combustion air and the thermal efficiency not, and fan itself be designed to can about the automatically design of the suitable angle of rotation, diffuse in the room on a large scale in the space so can rapidly warm air be blowed, have thermal cycle effect fast.
As shown in Figure 4, the utility model comprises a cellular ceramic substrate (4) at least, present embodiment is five cellular ceramic substrates (4), when a plurality of cellular ceramic substrates (4) constitute, these a plurality of cellular ceramic substrates (4) are when arrangement is provided with, and central authorities have a hole (A) that allows transmission shaft (10) wear;
As shown in Figure 5, when single the setting, central tool one penetration hole of the cellular ceramic substrate that the utility model proposes (4) (42), transmission shaft (10) is interspersed to be arranged in the penetration hole (42), and described fan shroud (2) is provided with the position at cellular ceramic substrate (4) and has fixed base (20) with fixing carrying cellular ceramic substrate (4).The utility model proposes fan motor (1) rear end and can be provided with auxiliary blower (11), by the setting of described auxiliary blower (11), auxiliary blower blade (3) is sent into outside air, and can the cooling fan motor.
The partition wall (43) that the cellular ceramic substrate that the utility model proposes (4) forms through hole (40) is set as cylindric (44) in the confluce, to eliminate the acute angle of through hole (40), so in use, can reduce stress and produce, can avoid partition wall (43) to rupture really in the confluce.As shown in Figure 6, existing cellular ceramic substrate (5) causes through hole acute angle (52) owing to form the partition wall (51) of through hole (50) in the confluce, described through hole acute angle (52) is when carrier uses, since fluid pass through to produce stress, often have in the facts of acute angle place fracture and take place, the utility model can address this problem.
