Description
[technical field]
This utility model relates to air cleaner technical field, a kind of domestic air purification dress
Put.
[background technology]
In recent years, along with increasing the weight of of haze weather, air purifier has become fast-selling household appliances.Domestic are empty
Gas purifier is mainly made up of electric fan and clean unit.Can be divided into two big classes:
One. indoor circulation formula air purifier: the overwhelming majority of existing commercially available depurator, is all this type.
It, by the air suction machine in room, machine place, sends this room back to after filtration, reach to reduce contained by air
Dust (comprising PM2.5) and the purpose of harmful chemical.Due to the accumulation of carbon dioxide and oxygen in room
The reason such as consumption, need intermittently window and change to outdoor air in room, drain indoor outmoded air.Thus can
Problem served by band.
1. during machine operation, the space air at its place can purify very well, but other rooms are due to air not
Energy convective exchange very well, can not sufficiently cleaned up wherein air;
2. window input is outdoor dust laden air, and the biggest visible particle falls, in making room
Furniture, ground are stained with dust, destroy cleaning;
3. due to wind direction, wind-force uncertain, it is impossible to grasp the suitable open degree of window and opening time length.
Air inflow is few, does not reaches the purpose of fully ventilation;Air inflow is too much, can excessively change air-conditioning or heating battalion
The Interior Temperature Environment made, winter room sub-cooled, summer, room superheated, increased air-conditioning and heating
The load of equipment, sinks money;
4. winter or summer joint, when people is in room, windows and can bring discomfort;People not time, cannot fit again
Time window opening-closing.
Two. the new blower fan of household small-size: new blower fan generally comprises two Fans, and is passed through porthole suction chamber outer space
Gas, input indoor after filtering, room air from porthole is discharged to room, is reached ventilation with this by another
Purpose.So, the outdoor air after only purifying could enter indoor, it is to avoid the problem brought of windowing.
The shortcoming of this product is:
1. have just enter into indoor fresh air and indoor original outmoded air mixing, have larger proportion the most again by
Being discharged to outdoor, therefore scavenging efficiency is relatively low, needs longer time of exchanging gas, causes the heat energy that room is bigger to damage
Consumption;
2., compared to indoor circulation formula air purifier, the filter of this kind of purification style needs the outdoor sky filtered
Tolerance is several times greater, and therefore the turnover rate of filter screen strengthens the most accordingly, adds the financial burden of user;
3. in order to reduce heat-energy losses, have employed heat exchanger, make machine construction complicated, cost increases.And
And after heat exchanger dust stratification, heat transfer efficiency declines, and user is also difficult to clean.
[utility model content]
After the purpose of this utility model is both can be filtered by outdoor air, input is indoor;Again that indoor are outmoded
Air is discharged to outdoor, it is achieved take a breath in room;Carry out the purification of the degree of depth;Realize the reasonable stream of air between room
Dynamic.The most integrated, make family's air cleaning system more reasonable, convenient use.
This utility model uses the method for " breathing " to take a breath, and its principle is: machine is connected with outdoor
Gas port, is outdoor air induction port when ventilation, is again that room air is discharged into outdoor air vent, enters
Gas, aerofluxus are carried out in turn, and each air inlet, evacuation time change indoor air pressure for degree with inconspicuous,
So repeatedly " breathe " until changing the room air of predetermined quantity.The indoor air inlet of machine with should
Adjacent room's connection in room, machine place, when ventilation and purification work, between two Room, air can be with Rational flow.
To achieve these goals, a kind of air cleaner of design, including:
A. common-use tunnel, inside is provided with blower fan,
B. outdoor channel, one or two position corresponding with common-use tunnel connection on one or two position,
On common-use tunnel, at least a position connected with outdoor channel is positioned at weather side, connects when there being two
During position, another communicating position is positioned at downwind side,
C. indoor channel, one or two position corresponding with common-use tunnel connection on one or two position,
It is equipped with valve, two communicating positions when there being the position that two connect, on common-use tunnel in its connectivity part
Lay respectively at upper and lower wind side,
D. purifying air air-out passage, on a position, a position of downwind side with common-use tunnel connects,
It is provided with valve in its connectivity part, in purifying air air-out passage, is provided with clean unit,
F. control circuit plate, blower fan is controlled to connect by control circuit plate by control signal wire.
The air outlet purifying air air-out passage is preferably provided with air pressure probe, air pressure probe
Control to connect by control circuit plate by control signal wire.
Air cleaner of the present utility model can also include that remote controller, described circuit board are provided with
The radio receiving transmitting module corresponding with remote controller.
Described clean unit is preferably one or more layers drainage screen.
Air cleaner also includes housing, and this air cleaner is positioned at housing, and indoor channel is with indoor
Space connection opening, outdoor channel connect with the exterior space opening, the purification of air cleaning air-out passage
Outlet is positioned at surface of shell.
On the architecture basics of above-mentioned air purifier, this air cleaner also has three below optimization side
Case:
Scheme one:
Outdoor channel is two positions corresponding with common-use tunnel connection on two positions, in the two connectivity part
It is provided with valve,
Indoor channel position with common-use tunnel weather side on a position connects,
The valve of the control room outer tunnel connection being positioned at downwind side purifies, with control, the valve that air air-out passage connects
Door drives opening and closing on the contrary by the first electric magnet connection,
The valve that connects with control room internal channel of valve of the control room outer tunnel connection being positioned at weather side passes through the
Two electric magnet connections drive opening and closing on the contrary.
The first described electric magnet and the second electric magnet can be connected control by control circuit plate and be turned on or off.
Scheme two:
Outdoor channel connects a position of weather side with common-use tunnel on a position, sets in connectivity part
It is equipped with valve,
Indoor channel is two positions corresponding with common-use tunnel connection on two positions,
The valve that connects with control room internal channel of valve of the control room outer tunnel connection being positioned at weather side passes through the
Three electric magnet connections drive opening and closing on the contrary,
Be positioned at valve at the indoor channel of downwind side and shared channel connection for by indoor channel to common-use tunnel
The check valve that direction is opened,
Purifying the valve at air duct and shared channel connection is to purifying air duct direction by common-use tunnel
The check valve opened.
3rd electric magnet is connected control by control circuit plate and is turned on or off.
Scheme three:
Outdoor channel position with common-use tunnel on a position connects,
Indoor channel position with common-use tunnel downwind side on a position connects,
The valve that indoor channel and shared channel connection position go out is for being opened by indoor channel to common-use tunnel direction
Check valve,
Purifying the valve at air duct and shared channel connection is to purifying air duct direction by common-use tunnel
The check valve opened.
This utility model is compared with the new blower fan of household small-size, and new blower fan is owing to wanting many electric fans, and knot
Structure is complicated, more can not air circulation flow between room, a room can only be purified regularly, not by users
Accept;Compared with normal air depurator, this utility model only increases some valves, in order to change sky
Air-flow to, be but provided with purification, ventilation, air circulation flow several functions, practical and convenient.
