The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also Fig. 1 to Fig. 3, the window air conditioner that the utility model first embodiment provides (be called for short window machine) 100 comprises chassis 10 and is positioned at indoor section and outdoor section on the described chassis 10.Described indoor section comprises wind wheel spiral case 20, is arranged at indoor wind wheel 22 and evaporimeter 23 in the described wind wheel spiral case 20.Described outdoor section comprises wind wheel air-ducting ring 30, is arranged at outdoor wind wheel 32, motor 33, condenser 34 and compressor 31 in the described wind wheel air-ducting ring 30.
Described motor 33 is provided with front rotary shaft 37 and back rotating shaft 38, and described front rotary shaft 37 is connected with described indoor wind wheel 22, and described back rotating shaft 38 is connected with described outdoor wind wheel 32.Described evaporimeter 23 and described condenser 34 are arranged in two outsides, front and back of described window air conditioner 100, and are connected with described compressor 31 by the pipe arrangement (not shown).
The outdoor section of described window air conditioner also comprises some wet curtains 35 and the condensed water that described condenser 34 produces is collected and cloth spills water-distributing device 36 to the described wet curtain 35 that described some wet curtains 35 are arranged in the periphery of the air intake space of formation between described wind wheel air-ducting ring 30 and the described wind wheel spiral case 20.
Please consult Fig. 4 simultaneously, when above-mentioned window air conditioner is worked, described water-distributing device 36 collects the condensed water that described condenser 34 produces, and cloth is spread across on the wet curtain 35, simultaneously described outdoor wind wheel 32 rotates and the generation negative pressure, force the extraneous unsaturated air porous of at first flowing through, moistening wet curtain 35 surfaces, make the aqueous water on wet curtain 35 surfaces under the air blast state than low humidity, directly evaporate and absorb airborne heat, make the sensible heat that is embodied by temperature in the air be converted into evaporation latent heat, thereby reduce the temperature of air, this air through cooling in advance flows through condenser 34 again and carries out heat exchange with it, can effectively improve the heat exchange efficiency of condenser 34.
Air by the outer wind wheel 32 of wet 35 pairs of suction chambers of curtain is lowered the temperature in advance, aqueous water on wet curtain 35 surfaces can not be splashed on the condenser 34, under the long-term operation of above-mentioned window air conditioner, the copper pipe of condenser 34 and aluminium fin are difficult for oxidation and rusting, copper pipe and fin surface can not form incrustation scale yet, thus the heat exchange efficiency of the service life of prolongation condenser 34, raising condenser 34.
In the present embodiment, described indoor wind wheel 22 is the oblique flow wind wheel, rather than centrifugal wind wheel, has overcome the low defective big with noise of efficient of centrifugal wind wheel.
In the present embodiment, described outdoor wind wheel 32 has been avoided water to be splashed to and has been made copper pipe and aluminium fin oxidation and rusting on the described condenser 34 for not with the axial-flow windwheel of hydrosphere, thereby has prolonged the service life of condenser 34.
Please consult Fig. 5 simultaneously, described compressor 31 is installed on the described chassis 10, and is arranged within the space that described some wet curtains 35 surround.
In the present embodiment, described window air conditioner also comprises some limited posts 40, and described limited post 40 is arranged between described wind wheel spiral case 20 and the described wind wheel air-ducting ring 30, in order to limit the distance between described wind wheel spiral case 20 and the described wind wheel air-ducting ring 30.When window air conditioner 100 in the running, avoid wind wheel spiral case 20 towards wind wheel air-ducting ring 30 motion or wind wheel air-ducting ring 30 towards 20 motions of wind wheel spiral case, and then make elements such as outdoor wind wheel 32 and motor 33 avoid external impacts.
Further, described condenser 34 is installed on the described wind wheel air-ducting ring 30, and described motor 33 is installed on the described chassis 10 by an electric machine support 39.
Please consult Fig. 1 and Fig. 2 again, described window air conditioner 100 also comprises the air draft part 50 that is installed between described wind wheel spiral case 20 and the described evaporimeter 23.The discharge duct 52 that described air draft part 50 comprises body 51 and is positioned at described body 51 tops and extends towards the front side of described window air conditioner 100, offer ventilating opening 53 on the described body 51, described ventilating opening 53 is over against described indoor wind wheel 22, in the depression 54 that described evaporimeter 23 forms between described discharge duct 52 and described body 51.
Further, the body 51 of described air draft part 50 is posted by on the described wind wheel spiral case 20, is formed with wind-collecting space 55 between the body 51 of described air draft part 50 and the described wind wheel spiral case 20, and described wind-collecting space 55 is connected with described discharge duct 52.
Further, described wind wheel spiral case 20 is provided with a putting part portion 21 that connects, the ventilating opening 53 of described body 51 is stretched in described putting part portion 21 by the rear portion of described wind wheel spiral case 20, described indoor wind wheel 22 is inserted in the described putting part portion 21, the bore of the ventilating opening 53 on the described body 51 is greater than the anterior opening bore that is positioned at of described putting part portion 21, and forming an air intake passage (indicating) in the periphery of the edge of described ventilating opening 53 and described putting part portion 21, described air intake passage is connected with described wind-collecting space 55.
Described oblique flow wind wheel rotates and produces negative pressure, the room air evaporimeter 23 of flowing through, and carry out heat exchange at described evaporimeter 23 places.Then, enter in the described wind-collecting space 55 by described air intake passage through the air-flow of heat exchange, air-flow comes together in the wind-collecting space 55, and is drained into indoorly by discharge duct 52, realizes the purpose to the room air cooling.In addition, wet curtain 35 reduces the air themperature of the outer wind wheel 32 of inlet chamber in advance, and the air that this temperature the is lower condenser 34 of flowing through has improved the heat exchange efficiency of condenser 34 with outdoor air.Please consult Fig. 6 simultaneously, with under the air quantity, the window air conditioner 100 that present embodiment provides reduces about 5%~6% than the motor general power of traditional window air conditioner.
Please consult Fig. 7 simultaneously, the window air conditioner 100 that window air conditioner 200 and the utility model first embodiment that the utility model second embodiment provides provides is roughly the same, its difference is: described compressor 31a is installed on the described chassis 10a, and be arranged at outside the space that described some wet curtain 35a surround, make that the layout of these warm curtains is compacter.
