Abstract
The utility model relates to the technical field of air conditioners, in particular to a baseboard device of a draught fan of an indoor unit of an air conditioner, and aims at providing the baseboard device capable of preventing the wind wheel of the indoor unit of the air conditioner from generating eddy current and improving the air outlet quantity and cooling capacity of the air conditioner. The technical scheme includes that the baseboard device comprises a baseboard, two wind wheels and a motor for driving the wind wheels, wherein housings of the wind wheels are fixedly connected with the baseboard, and the motor is fixedly connected with the baseboard through a support. The device further comprises an eddy current preventive hole arranged on the baseboard and under the motor.
Description
Technical field
The utility model relates to air-conditioning technical field, specifically is meant the fan bottom panel assembly in a kind of indoor apparatus of air conditioner.
Background technology
Convenient and the problem such as reduce cost for the transportation that makes air-conditioning, the heat exchanger of the indoor apparatus of air conditioner of most producers all adopts miniaturization, compact design.At present; The following shortcoming of indoor apparatus of air conditioner ubiquity: because the inner design of adopting miniaturization, compact of indoor set; So the spacing between two wind wheels that indoor set inside is used to dispel the heat is very short, generally is no more than 250mm, the air-out angle of flare of two wind wheels intersects each other; Distance between heat exchanger and the wind wheel is very little simultaneously, so there is resistance again in heat exchanger to the wind wheel air-out; The inside of indoor set can produce eddy current in this case, influences the air output of air-conditioning.
The utility model content
The utility model technical problem to be solved is: thus provide a kind of wind wheel of indoor apparatus of air conditioner that prevents to produce the fan bottom panel assembly that eddy current improves air-conditioning air output and heat-sinking capability.
The technical scheme of the utility model is a kind of fan bottom panel assembly, comprises a base plate, two wind wheels and a motor that is used to drive wind wheel; The shell of described wind wheel is fixedly connected with base plate; Described motor is fixedly connected with base plate through support; Described fan bottom panel assembly also comprises anti-eddy current hole; Described anti-eddy current hole is located on the base plate; Described anti-eddy current hole is positioned at the below of motor.
Can find out according to such scheme and the utlity model has following advantage: the spacing between two wind wheels is very short; The air-out angle of flare of two wind wheels intersects each other and is inevitable, again because spacing is very little between heat exchanger and the wind wheel, so will certainly in a delta-shaped region, form eddy current; The anti-eddy current hole that is located on the base plate has the effect of wind-guiding; Make that the eddy current in delta-shaped region has not existed originally, wind is discharged from anti-eddy current hole, and this fan bottom panel assembly can effectively be eliminated the eddy current that wind wheel is reported to the leadship after accomplishing a task and produced because of the air-out angle of flare in the indoor set; Increase air output, strengthen the coefficient of heat transfer.
As preferably, prevent that the diameter in eddy current hole is 6 millimeters; Its advantage is that the anti-eddy current hole of this diameter can reach optimum efficiency.
As preferably, prevent that the number in eddy current hole is four; Its advantage is that four anti-eddy current holes can effectively prevent eddy current.
As preferably, four anti-eddy current hole spread geometries are rhombus; Its advantage is regular shape, can have better guide effect to wind.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
Shown in accompanying drawing 1 to accompanying drawing 4, a kind of fan bottom panel assembly comprises a base plate 1, two wind wheels 2 and motors 3 that are used to drive wind wheel 2; The shell of described wind wheel 2 is fixedly connected with base plate 1; Described motor 3 is fixedly connected with base plate 1 through support; Described fan bottom panel assembly also comprises anti-eddy current hole 4; Described anti-eddy current hole 4 is located on the base plate 1; Described anti-eddy current hole 4 is positioned at the below of motor 3.The diameter in anti-eddy current hole 4 is 6 millimeters.The number in anti-eddy current hole 4 is four.Described four anti-eddy current hole 4 spread geometries are rhombus.
This description does not have restricted, and shown in the figure also is one of embodiment of the utility model, and practical structure is not limited thereto.If generally speaking those of ordinary skill in the art is enlightened by it, under the situation that does not break away from the utility model creation aim,, all should belong to the protection domain of the utility model without creationary frame mode similar and the embodiment of designing with this technical scheme.
