Specific embodiment
Below in conjunction with Figure of description, the present invention will be further described.
As shown in Fig. 1, Fig. 5-7, the two fans with fresh air function for switching wind direction by an air door of the invention are taken Warmer includes:
Cabinet 01 which is provided with indoor air outlet 12, indoor return air inlet 13, outdoor air port 14 with inner cavity 11, Indoor return air inlet 13 is connected to inner cavity 11;For the ease of assembly, cabinet 01 is package assembly and has side wall, indoor side air-out Mouth, indoor return air inlet, outdoor air port are assemblied on side wall;It further, can also be cabinet configuration decoration panel, decoration panel can Think the suspended ceiling pinch plate (being particularly suitable for Integral ceiling) cabinet being hidden in above furred ceiling, or be emerging in ceiling surface With cabinet keep assembly relation mask (being particularly suitable for gypsum furred ceiling);
First blower 02 is assemblied in the inner cavity 11 of cabinet comprising the first spiral case 21, the first centrifugal wind wheel 22, first Motor 23, the first centrifugal wind wheel are located in the first spiral case, and the first spiral case 21 has 24 He of the first air inlet for being open in inner cavity 11 First wind 25 of air outlet 12 on the inside of communication chamber;The first centrifugal wind wheel rotates under first motor driving, the sky of cabinets cavity Gas enters the first spiral case through the first air inlet and flows to indoor air outlet through the first air duct;
Second blower 03 is assemblied in the inner cavity 11 of cabinet comprising the second spiral case 31, the second centrifugal wind wheel 32, second Motor 33, the second centrifugal wind wheel 32 are located in the second spiral case 31, and the second spiral case has 34 He of the second air inlet for being open in inner cavity Second air duct 35 in the outer air port of communication chamber;The second centrifugal wind wheel rotates under the second motor driven, and the air of cabinets cavity is through the Two air inlets enter the second spiral case and flow to outdoor air port through the second air duct;
Air door 04 is driven by damper motor 41 and is at least being closed the first position (referring to Fig. 3) in outdoor air port, opening Switch between the second position (referring to fig. 2) in outdoor air port;It is intracorporal that damper motor can be assemblied in case according to the installation site of air door Appropriate location, the damper motor of diagram are assemblied on the second spiral case;
Electric heater unit 05 is laid on the exhaust pathway of the first blower, and the exhaust pathway of the first blower refers to from The first air duct to the air-flow of one blower drains into indoor path, and (for diagram, indoor air outlet upper connector is sub, then will pipe Son is connected to the other positions of indoor suspended ceiling;Other than diagram, indoor air outlet can also be connected directly to interior and hung Top).
The heater of above structure, indoor air outlet, the connection of indoor return air inlet (such as pass through pipeline when installing indoors Connection) it is indoor, outdoor air port connection (as connected by pipeline) is outdoor, then is closed by damper motor switching damper positions (state) It closes outside perhaps opening chamber air port and is aided with the first blower of starting or ventilation, circulating-heating, fresh air etc. can be realized in the second blower State.
As shown in Fig. 2, starting the second blower by damper motor switching damper positions (state) come air port 14 outside opening chamber 03, then indoor air flow is followed by indoor return air inlet 13, cabinets cavity 11, the second air inlet 34, the second centrifugal wind wheel 32, Two air ducts 35, outdoor 14 heel row of air port to outdoor, realize ventilatory, indoor wet turbid air are discharged outdoor.
As shown in figure 3, closing outdoor air port 11 by damper motor switching damper positions (state), start the first blower 02, then indoor air flow is followed by indoor return air inlet 13, cabinets cavity 11, the first air inlet 24, the first centrifugal wind wheel 22, It is back to interior after one air duct 25, indoor air outlet 12, opens electric heater unit 05 therebetween, that is, realizes and room air is followed Ring heating, realizes heating function.
As shown in figure 4, starting the first blower by damper motor switching damper positions (state) come air port 11 outside opening chamber 02, then outdoor airflow is not provided with communication port followed by outdoor air port 14, the second air duct 35, the second the second air duct spiral case 31( When closed state), it is the second air inlet 34, cabinets cavity 11, the first air inlet 24, the first spiral case 21, the first air duct 25, indoor It is flow to interior after side air-out mouth 12, for indoor supplement fresh air, realizes fresh air function;Meanwhile under the premise of no blocking air-flow, Indoor air flow is followed by indoor return air inlet, cabinets cavity, the first air inlet, the first spiral case, the first air duct, indoor side air-out Interior is back to after mouthful.
The realization (the mainly flow direction of air-flow) of above-mentioned function, the closing or unlatching dependent on outdoor air port and first Blower perhaps the unlatching of the second blower therefore air door can be located in the second air duct or outdoor air port in, and air door is specific Structure can be selected according to its installation site.
It is obstructed smaller when further, in order to flow air-flow and flows smooth, the adjacent outdoor air port 14 in the second air duct 35 Position open up communication port 36, air door rotation is assemblied in outdoor air port and communication port adjoining position.Air door 04 can be by air door The third place (referring to fig. 4) of air port and communication port outside motor driven to opening chamber simultaneously.Based on the structure, such as Fig. 4 is being realized Shown in fresh air function when, then outdoor airflow followed by outdoor air port, the second air duct, communication port, cabinets cavity, first air inlet It is flow to interior after mouth, the first spiral case, the first air duct, indoor air outlet, for indoor supplement fresh air.This structure is relative to second Air duct does not have the structure of communication port, shortens the circulation path of air-flow, and reduce when air-flow flows through the second centrifugal impeller by Resistance, flow it is more smoothly.
In order to make the second air inlet of the first air inlet of the first spiral case, the second spiral case be open in inner cavity, cabinet has one A rear cover 15 maintains gap 16 and the first air inlet is made to be open in inner cavity between first spiral case and rear cover, the second spiral case is with after Gap is maintained between lid makes the second air inlet be open in inner cavity.
It is clean in order to guarantee to flow to indoor air-flow, it is equipped in the gap between the first spiral case and rear cover around the first air inlet The tubular filter screen 26 of mouth, to be filtered to the air-flow for flowing to the first blower.
For the ease of installing, changeing filter screen and positioned to filter screen, after cover and be equipped with auxiliary lid 17, the one of filter screen End be inlaid in it is auxiliary cover, another end in contact of filter screen is on the first spiral case.
Electric heater unit 05 is ptc heater, is assemblied between the first air duct and indoor air outlet.
