Abstract
A kind of air conditioner room unit.It comprises chassis, front baffle, front panel, end face suction grille, multiple filter, indoor heat converter, indoor fan, fan electromotor, whirlpool tongue and wind deflector; Whirlpool tongue comprises whirlpool tongue framework, the straight wall of whirlpool tongue, connecting rod and several blades; Tongue straight wall in whirlpool is hollow structure, and is formed with multiple micropore on the surface in outside.Air conditioner room unit provided by the invention is that tongue straight wall in whirlpool on it is designed to hollow structure, and offer multiple micropore on its outer surface, the inside of the straight wall of whirlpool tongue will be entered like this when the wind blown out by indoor fan arrives this outer surface through these micropores, thus significantly can reduce the noise caused because of the straight wall of airflow strikes whirlpool tongue.In addition, because the outer surface of the straight wall of whirlpool tongue is skewed, therefore contribute to the flowing of air-flow, and the method by changing angle of inclination changes the shape of tongue place, whirlpool air swirl, thus can effectively reduce the noise produced by this eddy current.
Description
Technical field
The present invention relates to a kind of air-conditioner, particularly relate to a kind of air conditioner room unit.
Background technology
Usually, air-conditioner a kind ofly makes the refrigeration that the refrigerant of its inside carries out being made up of compression process, condensation process, expansion process and evaporation process or the device heating circulation.When air-conditioner carries out kind of refrigeration cycle, the refrigerant first inflow outdoor heat exchanger of high-temperature high-pressure state is become through compressor compression, in outdoor heat converter, this refrigerant will externally dispel the heat, then expansion valve is flowed to, and significantly reducing its temperature and pressure when flowing through expansion valve, this low temperature, low pressure refrigerant are by inflow indoor heat exchanger subsequently.In indoor heat converter, this refrigerant is by absorbing the heat of surrounding air, finally again flows back in compressor, so repeatedly circulates.Heat circulation then contrary with above-mentioned refrigerative circle system.Air-conditioner is divided into split type and integral type usually.Wherein detachable air conditioner has independently off-premises station and indoor set usually, and is separately positioned on outdoor and indoor.Described compression process, condensation process and expansion process are carried out in the off-premises station of air-conditioner, and evaporation process is then carry out in indoor set.In addition, indoor heat converter is mounted in indoor and has refrigeration or heat the device of effect, and when kind of refrigeration cycle, it has the effect of evaporimeter, is heating circulation time and then have the effect of condenser.Outdoor heat converter has the effect of condenser when kind of refrigeration cycle, heating circulation time and then have the effect of evaporimeter.Fig. 1 is the air conditioner room unit STRUCTURE DECOMPOSITION stereogram of prior art.Fig. 2 is the air conditioner room unit side direction structural representation shown in Fig. 1.As shown in Figure 1 and Figure 2, the air conditioner room unit of this prior art comprises: form the indoor set back side and bottom surface portions structure and it can be installed the chassis 1 of indoor set parts; Be arranged on the front end on chassis 1, form indoor set front end face, end face and two sides external structure, and before front end face and end face are respectively equipped with and the front baffle 3 of end face air inlet 20,21; Be arranged on air inlet 20 above and it be formed with the front panel 7 of suction grille 5 above; Be arranged on the end face suction grille 3 ' on end face air inlet 21; Be arranged between front baffle 3 and front panel 7, for multiple filters 9 ', 22 of filtering impurity from the air that suction grille 5 and end face suction grille 3 ' above suck; Be arranged on front baffle 3 inner front side, and the indoor heat converter 9 be connected with not shown off-premises station by refrigerant pipe 24; The rear of heat exchanger 9 disposed in the interior, for room air being drawn into the inside of indoor set, and is expelled back into the indoor fan 10 of the interior space by the air through indoor heat converter 9 heat exchange; Be positioned at the side of indoor fan 10, and output shaft is connected with indoor fan 10, for providing the fan electromotor 10 ' of rotary power for indoor fan 10; Be arranged on the whirlpool tongue 11 of front baffle 3 lower end; And be arranged on by the air outlet formed between chassis 1 and front baffle 3 lower end, for the wind deflector 15 of up-down adjustment air-out direction; Described whirlpool tongue 11 comprises whirlpool tongue framework 25, the straight wall 26 of whirlpool tongue, connecting rod 18 and several blades 16; Wherein whirlpool tongue framework 25 is in П shape, and opening backward, and its two ends are fixed on the lower end, both sides, the back side of front baffle 3; The two ends of the straight wall 26 of whirlpool tongue are connected to the open rearward end both sides of whirlpool tongue framework 25, form exhaust passage 13 thus between whirlpool tongue framework 25 and the straight wall 26 of whirlpool tongue; Several blade 16 standoff distances are arranged on connecting rod 18, and upper end thereof is in the edge of whirlpool tongue straight wall 26 front end face, therefore, it is possible to action simultaneously, for left and right adjusting air-out direction.After this air-conditioner starts, drive at fan electromotor 10 ' starts to rotate by indoor fan 10, thus room air is drawn into the inside of indoor set by suction grille 5 and end face suction grille 3 ' above, then this part air will flow to indoor heat converter 9.When flowing through indoor heat converter 9, the refrigerant from off-premises station with indoor heat converter 9 internal flow is carried out heat exchange by this air, thus temperature is raised or reduces, air afterwards through heat exchange will flow to indoor fan 10, exhaust passage 13 on inflow whirlpool, the below tongue 11 of then fan 10 indoor, finally under the guiding of wind deflector 15 and blade 16 by air outlet discharged to the interior space, thus under the interior space is remained on suitable temperature.But, there is following point in the air conditioner room unit of this prior art: as mentioned above, the installation site of whirlpool tongue 11 is on the flow path of air just, therefore the shock of air-flow will inevitably be subject to, so easily produce eddy current herein, result causes larger noise, thus causes being discontented with of consumer.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of air conditioner room unit that effectively can reduce noise.
In order to achieve the above object, air conditioner room unit provided by the invention comprises chassis, front baffle, front panel, end face suction grille, multiple filter, indoor heat converter, indoor fan, fan electromotor, whirlpool tongue and wind deflector; Described whirlpool tongue comprises whirlpool tongue framework, the straight wall of whirlpool tongue, connecting rod and several blades; Wherein tongue framework in whirlpool is П shape, and opening backward, and its two ends are fixed on the lower end, both sides, the back side of front baffle; The two ends of the straight wall of whirlpool tongue are connected to the open rearward end both sides of whirlpool tongue framework, form exhaust passage thus between whirlpool tongue framework and the straight wall of whirlpool tongue; Several blade standoff distances are arranged on connecting rod, and upper end thereof is in the edge of the straight wall front end face of whirlpool tongue, therefore, it is possible to action simultaneously, for left and right adjusting air-out direction; The described straight wall of whirlpool tongue is hollow structure, and is formed with multiple micropore on the surface in outside.
Described She Zhibi longitudinal cross-section, whirlpool is del.
