Abstract
The utility model relates to a window type air conditioner, which comprises a window type air conditioner composed of a compressor, a heat exchanger and relating pipelines thereof, a centrifugal fan and a casing body in the prior art, wherein, an airflow guide plate with a smooth arc surface is added in the turning position of an exhaust passage of the centrifugal fan. The airflow guide plate is fixedly connected to the top wall of the indoor heat exchanger. The length of the airflow guide plate is equal to that of an outlet of a spiral casing of the centrifugal fan. The airflow guide plate causes exhaust air flow to smoothly flow out without swirl formation and avoids air energy loss. Compared with the prior art, air output can be enhanced by 10% or so. If the air output is not changed, and the rotation speed of a motor is reduced, so noises can also be reduced. A test indicates that the noise of the window type air conditioner can be decreased by at least two decibels after the rotation speed of the motor is decreased.
Description
The utility model relates to a kind of wall-through type air conditioner.
For a long time, wall-through type air conditioner is always with the low favor that is subjected to people of its compact conformation, price.But, make its market sale be difficult to further expansion because its noise problem fails to be effectively controlled.Its generating noise is the result of mechanical oscillation, gas flow and liquid flow comprehensive function.By existing centrifugal window is found that with the analysis of air conditioner aerodynamic noise is one of main source of total noise of centrifuge.Rotation speed of fan height, gas channel are unreasonable to be the fundamental cause that produces aerodynamic noise.
The purpose of this utility model is that at the deficiencies in the prior art, providing a kind of can reduce rotation speed of fan, with the wall-through type air conditioner of effective attenuating total noise of centrifuge under the situation that keeps existing air output.
The purpose of this utility model is realized by following mode.
Air flow increasing and noise wall-through type air conditioner described in the utility model, comprise the wall-through type air conditioner of the prior art that constitutes by compressor, heat exchanger and associated pipe thereof, centrifugal fan and shell body, the exhaust passage of described centrifugal fan is vertical with the direction of the air outlet of shell body, it is characterized in that, have additional the gas-flow deflector of smooth curved surfaces to the place of turning back of shell body air outlet in described centrifugal fan exhaust passage, this plate be connected in snail tongue nearside turn back the place the indoor heat exchanger roof on, its length equals the length in centrifugal fan spiral case exit.Described gas-flow deflector can synthesize an integral body with the indoor heat exchanger dividing plate.Also can set up an overdraught guide plate that smooth curved surfaces is arranged again at the place of turning back, spiral case top.
Centrifugal blower wall-through type air conditioner of the prior art, the exhaust passage of its blower fan is vertical with the direction of housing air outlet, so need turning back after 90 °, cold (heat) wind that flows out from the blower fan exhaust passage could flow to space outerpace through the air channel of indoor heat exchanger wall and outer shell walls formation, because the place of turning back in described air channel is the right angle, this just makes air-flow form vortex around the corner, make the wind energy loss, thereby reduced air quantity.The user is in order to obtain big air quantity, and the way of usually taking to improve motor speed realizes.The raising of motor speed must make air-flow velocity increasing in the blower fan, and noise increases thereupon.The improvement that the utility model is made is, set up the streamlined gas-flow deflector of smooth curved surfaces at the place of turning back, air channel, makes to discharge air-flow along the smooth and easy outflow of guide plate, no longer forms vortex, avoided the loss of wind energy, objectively played the effect that increases air output.Compared to existing technology, under the identical situation of air output, the motor speed of use is much lower, and this has not only reduced the noise that is produced by mechanical oscillation, and has reduced the air velocity in the blower fan, and noise is reduced thereupon.Actual test shows, a wall-through type air conditioner of the prior art, set up gas-flow deflector described in the utility model after, under the situation that does not increase noise, can make its air output improve about 10%; If keep air output same as the prior art, then lower motor speed after, its noise will reduce more than 2 decibels.
This improvement that the utility model is made, its structure is simple especially, convenient enforcement.Relative complete machine, the cost of setting up gas-flow deflector is very little, but the good wind noise reduction effect that increases is arranged, this will help increasing the market of wall-through type air conditioner.
Be described further below by embodiment and accompanying drawing thereof.
Fig. 1 is a kind of example structure schematic diagram of the present utility model.
Fig. 2 is that the A of Fig. 1 is to view.
Referring to Fig. 1, (1) is shell body, (2) be the outdoor machine part of the existing wall-through type air conditioner that constitutes by compressor, condenser etc., (3) be median septum, (4) be centrifugal fan, (5) be indoor heat exchanger, (6) be panel, (7) be the gas-flow deflector of setting up described in the utility model, its cross section for the diagram streamlined, it be connected in snail tongue nearside turn back the place the heat exchanger roof on, the air-flow of discharging from centrifugal blower along guide plate smooth and easy flow to indoor, do not form vortex, reduced the wind energy loss, this helps improving air output.If only need air output same as the prior art, motor speed is lowered, thereby can effectively reduce the noise of complete machine.(8) be to set up the overdraught guide plate of turning back and locating on the spiral case top, its existence, circulation has played booster action to airflow smooth.Arrow is represented the air current flow direction among the figure.
Referring to Fig. 2,, removed panel (6) among this figure for expressing clearly.(7) be the gas-flow deflector of setting up described in the utility model, the same length in its length and centrifugal fan spiral case (9) exit.(10) be the snail tongue of centrifugal fan.
Claims (3)
1. air flow increasing and noise wall-through type air conditioner, comprise the wall-through type air conditioner of the prior art that constitutes by compressor, heat exchanger and associated pipe thereof, centrifugal fan and shell body, the exhaust passage of described centrifugal fan is vertical with the direction of the air outlet of shell body, it is characterized in that, have additional the gas-flow deflector of smooth curved surfaces to the place of turning back of shell body air outlet in described centrifugal fan exhaust passage, this plate be connected in snail tongue nearside turn back the place the indoor heat exchanger roof on, its length equals the length in centrifugal fan spiral case exit.
2. wall-through type air conditioner as claimed in claim 1 is characterized in that described gas-flow deflector can synthesize an integral body with the indoor heat exchanger roof.
3. wall-through type air conditioner as claimed in claim 1 is characterized in that also can setting up at the place of turning back, spiral case top an overdraught guide plate that smooth curved surfaces is arranged again.
