New wind state: it is closed using louver structure 7-1 is closed to control indoor air inlet 7, while setting equipment air inlet air port 1
Standby air inlet air port commutation air-valve 1-1 is opened and (is located at the position d), and air duct commutation air-valve 8 is opened into air draft state and (is located at the position e, i.e.,
Closed to heating side), the air-valve 3-2 that commutates of the equipment outlet air air port in equipment outlet air air port 3 is opened to the fresh air side air outlet 3-3
(being located at the position b), the air port 3-1 that takes a breath at this time are in close state.Power is provided by blower 6, is passed through by equipment air inlet air port 1
Pipeline is introduced new air into from outdoor be filtered by air-purifying module 4 after, via fresh air air outlet 3-3 send out.
And clean fresh air is sent into interior by fresh air air outlet 3-3 cooperation pipeline, meanwhile, by fresh air air outlet
3-3 is connected with branch line, different branch lines can also be connected the demand spaces such as bathing room, horizontal and study.
When using ventilatory of the multifunctional novel blower of the present embodiment, the louver structure 7-1 of indoor air inlet 7, which is in, to be opened
State is opened, the equipment air inlet air port commutation air-valve 1-1 in equipment air inlet air port 1 is in close state the air duct commutation (in the position c)
Air-valve 8 is opened into air draft state (being located at the position e, i.e., close to heating side), and the equipment outlet air air port in equipment outlet air air port 3 is changed
It opens to air-valve 3-2 to the ventilation side air port 3-1 and (is in the position a, fresh air air outlet 3-3 is in close state).It is provided by blower 6
Power, interior enters by indoor circulation air inlet 7 is again expelled to room air by being connected to the pipeline of ventilation air port 3-1
It is outdoor.
When the use heating function of the multifunctional novel blower of the present embodiment, at the louver structure 7-1 of control indoor air inlet 7
In open state, and the equipment air inlet air port commutation air-valve 1-1 in equipment air inlet air port 1 is in close state (in the position c), wind
Road commutation air-valve 8 is opened into heating state (being located at the position f, i.e., open to heating side), provides power, indoor process by blower 6
Indoor circulation air inlet 7 is sent directly into interior into after again heating room air by electric heater 5 again, plays indoor heating
Effect.At this point, i.e. can be at the position a can also be in b to the equipment outlet air air port commutation air-valve 3-2 in equipment outlet air air port 3
It sets, carries out bathing indoor air circulation for assisting, prevent bath indoor oxygen content too low and anoxic be in the presence of.
Based on above-mentioned working condition, defect that the multifunctional new wind eedle of the present embodiment has a single function existing new blower into
Row improves, between realizing that equipment different function is realized in the switching of circulation line access by the selectivity switching of three groups of air-valves
Switching.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
