Detailed description of the invention
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 warmer with new wind function by an air door switching wind direction of the present invention comprises:
Casing 01, it has inner chamber 11, which is provided with indoor air outlet 12, indoor return air inlet 13, outdoor air port 14, indoor return air inlet 13 communication with cavity 11; For the ease of assembling, casing 01 is package assembly and has sidewall, and indoor air outlet, indoor return air inlet, outdoor air port are assemblied on sidewall; Further, it can also be cabinet configuration decoration panel, decoration panel can for being hidden in the suspended ceiling pinch plate (being particularly useful for Integral ceiling) above furred ceiling by casing, also can keep the face shield of assembly relation (being particularly useful for gypsum furred ceiling) for what be emerging in ceiling surface with casing;
First blower fan 02, it is assemblied in the inner chamber 11 of casing, it comprises the first spiral case 21, first centrifugal wind wheel 22, first motor 23, first centrifugal wind wheel and is positioned at the first spiral case, the first spiral case 21 have be open in inner chamber 11 the first air inlet 24 and communication chamber inside the first wind 25 road of air outlet 12; Under the first motor drives, the first centrifugal wind wheel rotates, and the air of cabinets cavity enters the first spiral case through the first air inlet and flows to indoor air outlet through the first air channel;
Second blower fan 03, it is assemblied in the inner chamber 11 of casing, it comprises the second spiral case 31, second centrifugal wind wheel 32, second motor 33, second centrifugal wind wheel 32 and is positioned at the second air channel 35 that the second spiral case 31, second spiral case has the second air inlet 34 and outer air port of communication chamber being open in inner chamber; Under the second motor drives, the second centrifugal wind wheel rotates, and the air of cabinets cavity enters the second spiral case through the second air inlet and flows to outdoor air port through the second air channel;
Air door 04, its driven by damper motor 41 and at least outside close chamber outside the primary importance (see Fig. 3) in air port, opening chamber air port the second place (see Fig. 2) between switch; Damper motor can be assemblied in the appropriate location in casing according to the installation site of air door, illustrated damper motor is assemblied on the second spiral case;
Electric heater unit 05, it is laid on the exhaust pathway of the first blower fan, the exhaust pathway of the first blower fan refer to from the first air channel to the air-flow of the first blower fan drain into indoor path (with regard to diagram, connecting pipe on the air outlet of indoor, then other position pipe being connected to indoor suspended ceiling; Except diagram, also indoor air outlet can be connected directly to indoor suspended ceiling).
The warmer of said structure, indoor air outlet when being arranged on indoor, that indoor return air inlet is communicated with (as connected by pipeline) is indoor, it is outdoor that outdoor air port is communicated with (as connected by pipeline), then switch damper positions (state) by damper motor to close or the outer air port of opening chamber, and be aided with startup first blower fan or the second blower fan can realize the state such as ventilation, circulating-heating, newly wind.
As shown in Figure 2, switch damper positions (state) by damper motor and come air port 14 outside opening chamber, start the second blower fan 03, then indoor air flow drains into outdoor after flowing through indoor return air inlet 13, cabinets cavity 11, second air inlet 34, second centrifugal wind wheel 32, second air channel 35, outdoor air port 14 successively, realize ventilatory, by outside the wet turbid air discharge chamber of indoor.
As shown in Figure 3, switch damper positions (state) by damper motor and come air port 11 outside close chamber, start the first blower fan 02, then indoor air flow is back to indoor after flowing through indoor return air inlet 13, cabinets cavity 11, first air inlet 24, first centrifugal wind wheel 22, first air channel 25, indoor air outlet 12 successively, open electric heater unit 05 therebetween, namely realize, to the circulating-heating of room air, realizing heating function.
As shown in Figure 4, switch damper positions (state) by damper motor and come air port 11 outside opening chamber, start the first blower fan 02, then outdoor airflow flows through closed state when spiral case 31(second air channel, air channel 35, second, outdoor air port 14, second does not arrange communication port successively), the second air inlet 34, cabinets cavity 11, first air inlet 24, first spiral case 21, first air channel 25, flow to indoor after indoor air outlet 12, for indoor supplement new wind, realize new wind function; Meanwhile, under the prerequisite not blocking air-flow, indoor air flow is back to indoor after flowing through indoor return air inlet, cabinets cavity, the first air inlet, the first spiral case, the first air channel, indoor air outlet successively.
The realization (mainly the flow direction of air-flow) of above-mentioned functions, depend on the closedown in outdoor air port or the unlatching of unlatching and the first blower fan or the second blower fan, therefore air door can be located in the second air channel or in outdoor air port, and the concrete structure of air door can be selected according to its installation site.
Further, flow smooth and easy to make to be obstructed less during air current flow, connected entrance 36 is offered in the position that the second air channel 35 adjoins outdoor air port 14, and what air door rotated is assemblied in outdoor air port and connected entrance adjoining position.Air door 04 can be urged to the 3rd position (see Fig. 4) of air port and connected entrance outside simultaneously opening chamber by damper motor.Based on this structure, when realizing new wind function as shown in Figure 4, then outdoor airflow flow to indoor after flowing through outdoor air port, the second air channel, connected entrance, cabinets cavity, the first air inlet, the first spiral case, the first air channel, indoor air outlet successively, for indoor supplement new wind.This structure does not have the structure of communication port relative to the second air channel, shortens the circulation path of air-flow, and the resistance be subject to when decreasing airflow passes the second centrifugal impeller, flow more smooth and easy.
In order to make the first air inlet of the first spiral case, the second air inlet of the second spiral case is open in inner chamber, casing has a bonnet 15, maintaining gap 16 between first spiral case and bonnet makes the first air inlet be open in inner chamber, maintains gap and make the second air inlet be open in inner chamber between the second spiral case and bonnet.
Clean in order to ensure to flow to indoor air-flow, be provided with the tubular screen pack 26 around the first air inlet in the gap between the first spiral case and bonnet, in order to filter the air-flow flowing to the first blower fan.
For the ease of installing, changeing screen pack and locate screen pack, bonnet is equipped with auxiliary lid 17, one end of screen pack is inlaid in auxiliary covering, and the other end contact of screen pack is on the first spiral case.
Electric heater unit 05 is ptc heater, and it is assemblied between the first air channel and indoor air outlet.
