Description
Technical field
The invention belongs to Air conditioner design fields, and in particular to a kind of air-conditioning draught fan.
Background technique
Typically now office space or family are equipped with air-conditioning, and air-conditioning carries the function for environment temperature reduction and heating,
The electric heater unit that air-conditioning uses in the prior art is independent structure.Existing number of patent application is 201210146218.9, patent
The patent of invention of entitled electric heater unit and air conditioner, the patent provides a kind of electric heater units, due to cooling fin part
It include adjacent with joint face to enter stream interface；The stream interface that enters of cooling fin part is inclined-plane, is intersected with the center line of heat-generating pipe in oblique
Angle.The present invention also provides a kind of air conditioner, electric heater unit is located at the bending position side of evaporator；The electric heater unit
Setting enters the wind region in ventilation device.This technical solution has the following problems that the electric heater unit of independent structure can be in air-conditioning
Very big windage is caused in inside, and therefore causes wind resistance noise excessive, and the electric heater unit being separately provided makes in air-conditioning
Structure is complicated in portion, causes air-conditioning assembly efficiency low.
Summary of the invention
Big in order to solve wind resistance noise existing in the prior art, the problem of air-conditioning internal structure complexity, the present invention proposes
A kind of new air-conditioning fan blade, electric heater unit is integrated with fan blade, reduce number of parts, improves heating effect.
The specific technical solution of the present invention is as follows:
A kind of air-conditioning draught fan, the air-conditioning draught fan are provided with electric heater unit.
Wherein, the electric heater unit is set to the blade interior of air-conditioning draught fan.
Wherein, the electric heater unit is set as the partial blade of air-conditioning draught fan.
Wherein, the electric heater unit is set as the part impeller of air-conditioning draught fan.
Wherein, the air-conditioning draught fan is axial flow blower or centrifugal blower or cross flow fan.
Wherein, the connecting line of the electric heater unit is arranged on air-conditioning draught fan inside or surface.
Wherein, when the air-conditioning draught fan is cross flow fan, the air-conditioning draught fan is additionally provided with brush, the brush and electricity
The connection of heating device connecting line, the brush are electric heater unit power supply.
A kind of air-conditioning is provided with air-conditioning draught fan described in any of the above-described technical solution.
Beneficial effect
The problems such as by can solve windage, auxiliary thermal noise for electric heater unit and fan blade integrated setting, improves user
Comfort；Electric heating can lead out heat more with the wind in fan blade rotary course, and heating effect is more preferable；Subtract
Few number of parts, can save air conditioner internal space, solve the problems, such as that assembly is inefficient.
Detailed description of the invention
Fig. 1 is the cross flow fan fan blade schematic diagram for being provided with electric heater unit
Fig. 2 is the centrifugal blower fan blade schematic diagram for being provided with electric heater unit
Fig. 3 is the axial fan blade schematic diagram for being provided with electric heater unit
Wherein, 1 is electric heater unit.
Specific embodiment
Embodiment 1
A kind of air conditioner, it includes evaporator, bottom case component and cross flow fans.As shown in Figure 1, the leaf of the cross flow fan
Electric heating module is provided on wheel.Cross-flow fan impeller is plastic part in the present embodiment, by electric heating module and cross flow fan into
Row integrated injection moulding, electric heating module become one of impeller of cross flow fan, and the connecting line of electric heating module is equally infused
Modeling is powered to the one or both ends of through-flow fan blade by the way of brush into cross flow fan, so arranges, avoids
Connecting line is difficult to the problem of being arranged.
By the way that by electric heating module and cross flow fan integrated setting, when air-conditioning heating works, electric heating module, which follows, is passed through
Stream fan blade rotates together, and electric heating module heating power when air-flow flows through through-flow fan blade, is electrically heated module and directly heats,
The heat of generation compares the electric heating module being separately provided and is easier to be taken out of by air-flow, improves heating efficiency.Due to eliminating
Individual electric heater unit, air-flow do not hinder on the way to through-flow fan blade flowing, and avoiding problems the electricity being separately provided originally to add
Windage caused by thermal, so as to avoid auxiliary thermal noise；Simultaneously because a part is arranged less, air-conditioning internal structure is more
To be succinct, when assembly, is more convenient.
Embodiment 2
As shown in Fig. 2, the air conditioner is provided with centrifugal blower in the present embodiment, the electric heating module is configured to
The shape of centrifugation blade blade, and become a part of centrifugation blade component, it is rounded to be evenly distributed in fan blade component.
The connecting line of the electric heater unit is installed in the surface on centrifugation blade chassis, and is powered by brush for it.
After powered up, the electric heating module of profiling gives out heat to the air conditioner of the present embodiment, and rotates with fan blade,
The heat of generation is more easily taken out of with the wind, will not generate auxiliary thermal noise, at the same electric heating it is integrated with fan blade after can reduce one
Part, air-conditioning internal structure is more succinct, and when assembly is more convenient.
Embodiment 3
As shown in figure 3, the air conditioner is provided with axial flow blower, the electric heating module and axis stream wind in the present embodiment
The fan blade integrated injection moulding of machine, electric heating module can be round or other shapes from the surface of fan blade, the electric heating module
Shape, the connecting line of the electric heating module are arranged on the surface or inside of fan blade, converge at the axle center of fan blade, pass through electricity
Brush is powered for it.
At work, electric heating module electrified regulation, heat generates on the fan blade surface of axial flow blower this air conditioner, follows
Air-flow is quickly discharged, and will not generate auxiliary thermal noise, at the same electric heating it is integrated with fan blade after can reduce by a part, in air-conditioning
Portion's structure is more succinct, and when assembly is more convenient.
