Description
Technical field:
The utility model relates to mechanical field, particularly relates to household heater and indoor fresh air ventilating system, particularly a kind of air channel switching mechanism.
Background technology:
Household heater and ventilation air interchange system generally possess blowing and ventilatory, and realizing these functions needs to arrange corresponding air channel.According to user need select work at present air channel, to realize corresponding function.In prior art, in order to realize the switching of blowing ventilatory, have the mode adopting bi-motor to add two air channel, although achieve this function like this, add motor and air channel quantity, complete machine cost promotes, and machine appearance and size increases greatly, and increases energy resource consumption; Adopt the mode of single air channel, either-rotation motor in addition, this kind of mode respectively opens an air outlet in motor both sides, although achieve blowing ventilation handoff functionality, but air outlet arranges and destroys Archimedes's air intake Luo Dao, make blowing, scavenging efficiency reduction, simultaneously owing to can not realize the problem of Seal Design, air quantity has loss, can not effectively realize air channel handoff functionality.
Summary of the invention:
The purpose of this utility model is to provide a kind of air channel switching mechanism, and described this air channel switching mechanism will solve the technical problem that in prior art, household heater and central ventilation system can not switch effectively between blowing function and indoor fresh air ventilating function, efficiency of energy utilization is low.
This air channel of the present utility model switching mechanism, comprise an airduct, wherein, described airduct comprises an entrance, one first outlet and one second outlet, described entrance and described first export and second export between be provided with an air door, described air door is connected with airduct by a swing mechanism, air door has a primary importance and a second place in airduct, gas channel between entrance and second export when described primary importance by air door blocks, gas channel between entrance and first export when the described second place by air door blocks.
Further, the first described outlet and the second outlet are side by side, first outlet and the second outlet are positioned at phase the same side of airduct, entrance is positioned at and exports with first and second to export contrary airduct side, from entrance to first outlet or second outlet direction on, in airduct, the section of gas channel is all rectangular, air door is rectangular, the upper and lower sides of air door is connected with airduct each via rotating shaft, described rotating shaft is positioned on the center line of entrance, airduct is fixedly installed an electromagnet, an armature is provided with in described electromagnet, described armature is connected with a straight line connecting rod, described straight line connecting rod is connected with a crank by bearing pin, one end of described crank is connected with air door or rotating shaft.
Further, the periphery of air door is provided with sealing strip.
Further, be provided with a cambered plate between the first described outlet and the second outlet, one end of air door contacts with described cambered plate.
The utility model is compared with prior art, and its effect is actively with obvious.The utility model arranges two outlets in one end of airduct, between two outlets and the air flow inlet of airduct, turnable air door is set, the air channel realized between two outlets and airduct air flow inlet switches, blowing/ventilatory can be realized switch, also 2 blowings or 2 ventilatory single-point opening and closing functions switchings can be realized, the both sides of air door are provided with sealing strip, can play cushioning effect latter stage in air door action, also can play airtight effect simultaneously.The utility model intactly remains Archimedes's air intake Luo Dao, and switched the switching realizing air channel by air door, package size is little, and single motor runs, and saves electric energy.
