The specific embodiment
Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.Need to prove, in the situation that do not conflict, embodiment and the feature among the embodiment among the application can make up mutually.
Shown in Fig. 1～3, according to embodiments of the invention, air-conditioning air-breather equipment comprises housing 10, suction seal chamber 20, reversal valve 30, air inlet switching mechanism 40, indoor passage 50, outside passage 60 and air-breathing motor 70.
Be provided with square air inlet 22 on the first side wall 23 of suction seal chamber 20, the filter chamber of 20 inside, suction seal chamber is communicated with the ventilation lumen of housing 10 inside.Air inlet 22 can be arranged on the same sidewall with screen pack 21, also can be separately positioned on the different sidewalls, air inlet 22 in the present embodiment is arranged on the different lateral with screen pack 21, and screen pack 21 is arranged on the larger lateral wall of area, can overcome by enlarging the air inlet area like this resistance of 21 pairs of gases of screen pack, improve the efficient of air inlet.
20 inside, suction seal chamber are fixed with air-breathing motor 70, and air-breathing motor 70 is provided with air entry 71 and gas outlet 72, and wherein air entry 71 is corresponding with screen pack 21, and air entry 71 is communicated with the filter chamber of suction seal chamber 20, and gas outlet 72 is communicated with air-out passage.
In conjunction with referring to Fig. 3～9, air inlet switching mechanism 40 is arranged on housing 10 inside, comprises guide rail, slide damper 42 and connecting rod 43.Its middle guide is parallel with the first side wall 23, comprises the first guide rail 41 and the second guide rail 46 that are separately positioned on 23 two opposite edges of the first side wall.Be provided with the chute that arranges along the glide direction of slide damper 42 on the guide rail, chute comprises the first chute 411 that is separately positioned on the first guide rail 41 and the second guide rail 46, and the second chute 461, the second chutes 461 that are separately positioned on the first guide rail 41 and the second guide rail 46 arrange corresponding to the first chute 411 along the glide direction of slide damper 42.The first guide rail 41 and the second guide rail 46 are removable rail.The inlet close end of the first chute 411 and the second chute 461 is bent to the wall of the first side wall 23.
Connecting rod 43 comprises the hinged end that is positioned at first end and is positioned at the crank end of the second end, crank end is arranged on the position of departing from the spindle central of reversal valve 30 on the side plate 322 of reversing plate 32 pivotly, hinged end is hinged on the slide damper 42, drives slide damper 42 and slides along guide rail.
Reversing plate 32 can rotate around the axis of valve body 31.Reversing plate 32 comprises along the dividing plate 321 of the axial direction setting of valve body 31 and two ends and the applying of valve body 31 inwalls, and the semicircle side plate 322 that covers valve body 31 outsides and be fixedly connected with dividing plate 321, and dividing plate 321 is through the axis of valve bodies 31.Dividing plate 321 matches with side plate 322, is closed side and open sides with reversal valve 30 interior separations.Along with the rotation of reversing plate 32, can make the first reversal valve opening and the 3rd reversal valve opening be co-located at the closed side, be the first duty of air interchanger.Perhaps can make the second reversal valve opening and the 3rd reversal valve opening be co-located at the closed side, be the second duty of air interchanger.
When conversion motor 33 drove reversing plates 32 and rotates, connecting rod 43 rotated thereupon, and drive slide damper 42 is done rectilinear motion, opening and closing of fault air inlet 22 along guide rail.
In the time the air venting of the interior space need to being arrived the exterior space, reversing plate 32 turns to the second duty that makes the second reversal valve opening and the 3rd reversal valve opening be co-located at the closed side under conversion motor 33 drives, this moment, indoor passage 50 was communicated with the open sides of reversal valve 30.Conversion motor 33 drives slide damper 42 motions, until slide damper 42 is in the first baffle position, air inlet 22 is opened.The air of the interior space enters the open sides of reversal valve 30 from indoor passage 50, then the attraction owing to the air entry 71 of air-breathing motor 70 is circulated to suction seal chamber 20.This moment is because air inlet 22 unlatchings, air enters the resistance of suction seal chamber 20 much smaller than the resistance that enters suction seal chamber 20 by screen pack 21 by air inlet 22, enter suction seal chamber 20 so be inhaled into the air overwhelming majority of air entry 71 by air inlet 22, screen pack 21 is left unused.The air that enters air-breathing motor 70 enters the closed side through gas outlet 72, then is discharged into the exterior space by outside passage 60.Whole process to exterior space exhaust does not need basically through screen pack 21, thereby has reduced the frequency of utilization of screen pack 21.
When needs are carried fresh air to the interior space, reversing plate 32 turns to the first duty that makes the first reversal valve opening and the 3rd reversal valve opening be co-located at the closed side under conversion motor 33 drives, this moment, outside passage 60 was communicated with the open sides of reversal valve 30.Conversion motor 33 drives slide damper 42 motions, until slide damper 42 is in the second baffle position, with air inlet 22 sealings.The air of the exterior space enters the open sides of reversal valve 30 through outside passage 60, then the attraction owing to the air entry 71 of air-breathing motor 70 is circulated to suction seal chamber 20.This moment is because air inlet 22 sealing, and air can only enter air-breathing motor 70 in the suction seal chamber 20 by screen pack 21, so screen pack 21 is in running order, with particle removal harmful in the air.The fresh air that process is filtered enters the closed side from the gas outlet 72 of air-breathing motor 70, then enters the interior space by indoor passage 50, has guaranteed to make indoor environment more comfortable to the air quality of interior space conveying.
According to embodiments of the invention, air-conditioner comprises the air interchanger that is communicated with indoor set and off-premises station respectively, this air interchanger comprises above-mentioned any air interchanger, and the shell chamber inner joint of air interchanger is communicated to indoor set, and the shell chamber external tapping of air interchanger is communicated to off-premises station.
From above description, can find out, the technique effect of the above embodiments of the present invention is, by the air inlet switching mechanism is set, make air interchanger when carrying out two-way ventilation, the route of flowing through of synchronous change gas, process screen pack when realization is blown to the interior space, during to exterior space air draft without the purpose of screen pack, thereby reduce the frequency of utilization of screen pack, prolong the service life of screen pack.This air inlet switching mechanism is the rack-and-pinion slide construction in addition, and is simple in structure, also can not increase too much the cost of air interchanger the time easy for installation.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
