Utensil has the air intake passage and air-out passage for being isolated from each other and capable of carrying out heat exchange, and air intake passage and air-out passage are by several
Gap is constituted；
The inner cavity of babinet 100 is divided into outdoor side chamber 105, indoor side chamber 106 by bidirectional flow total-heat exchanger；
Outdoor side chamber 105, indoor side chamber 106 are spaced as upper layer and lower layer, and outdoor side chamber 105 is spaced as on outside
Chamber 107, outside cavity of resorption 108, indoor side chamber 106 are spaced as indoor epicoele 109, indoor cavity of resorption 110；
As shown in figure 8, the arrival end of air intake passage and the outlet end of air-out passage are located outside the different layers of side chamber, specifically
, the arrival end of air intake passage is located outside side cavity of resorption 108, and the outlet end of air-out passage is located outside side epicoele 107；Air inlet is logical
The outlet end in road and the arrival end of air-out passage are located at the different layers of indoor side chamber, specifically, the outlet end of air intake passage is located at
The arrival end of indoor epicoele 109, air-out passage is located at indoor cavity of resorption 110；Therefore, the arrival end of air intake passage and air inlet are logical
The outlet end different layers of the outlet end different layers in road, the arrival end of air-out passage and air-out passage, thus with the air inlet that intersects
Channel, air-out passage are adapted；When it is implemented, also the arrival end of air intake passage can be enabled to be located outside side epicoele, air-out passage
Outlet end be located outside side cavity of resorption, the outlet end of air intake passage is located at indoor cavity of resorption, and the arrival end of air-out passage is located at room
Inside epicoele is equivalent at this time by structure turn-over shown in Fig. 5-7；
Indoor breeze fan 300 is centrifugal blower and is located at indoor side chamber 106, the centrifugal wind wheel 301 of indoor breeze fan
Axial direction it is consistent with the thickness direction of babinet, the air inlet of indoor breeze fan 300 and the outlet end of air intake passage are open in
Indoor epicoele 109 and be connected to, the air outlet of indoor breeze fan 300 is connected to indoor air-out pipe connection 102；
Outdoor breeze fan 200 is centrifugal blower and is located outside side chamber 105, the centrifugal wind wheel 201 of outdoor breeze fan
Axial direction it is consistent with the thickness direction of babinet, the air inlet of outdoor breeze fan 200 and the outlet end of air-out passage are open in

Energy exchange.
The bidirectional flow complete-hot fresh air device enables the axial direction of the centrifugal wind wheel of centrifugal blower consistent with the thickness direction of babinet, by
This reduces product thickness, and product thickness can reach 200mm-220mm.Also, it is the outdoor side chamber of babinet, indoor side chamber is equal
It separates and is respectively used to air inlet, exhaust for upper layer and lower layer, to reduce internal duct resistance, thus while reducing product thickness,
Ensure same scavenging efficiency without increasing power of fan.
Specifically, babinet includes upper cover plate 111, lower cover（It hides and is not shown in figure）, outdoor side chamber, indoor side chamber quilt
Lateral partitions between upper cover plate, lower cover separate as upper layer and lower layer.Partition board is independent plank or/and constitutes centrifugation wind
The plank of the spiral case of wheel.These plank preferred foams plates of plank are to reduce the weight of entire product.
In order to flow to indoor outdoor air outside clean room, it is equipped with filter device 500 in the arrival end of air intake passage, specifically
Be that filter device is located at intracavitary under outside.The filter device preferably includes slightly to imitate metal screen, H13 grades of HEPA strainers.
For the ease of maintenance, the side wall of babinet is equipped with manhole and covers the access panel of manhole, filter device, double
It is slidedly assemblied in babinet through manhole to stream total-heat exchanger.Therefore, filter device, bidirectional flow total-heat exchanger are made as always
At form to take out and to reinstall.
In spring and autumn, since indoor/outdoor temperature-difference is smaller, at this moment as allowed room air to carry out heat exchange with outdoor air again,
Then efficiency is very low, and by increasing internal duct resistance when bidirectional flow total-heat exchanger, increases power of fan, the electricity charge are lost.For
It avoids this situation from occurring, connection indoor return air is equipped in babinet and takes over bypass passageways with outdoor breeze fan air inlet
112, it is configured with for bypass passageways for controlling bypass passageways, the first switching air door 113 that air-out passage turns off or on.Pass through
Switching first switching air door, can enable indoor return air take over connection bypass passageways, close air-out passage or connection air-out passage,
Close bypass passageways.Preferably, adjacent to the arrival end of air-out passage, the first switching air door is located to be bypassed the arrival end of bypass passageways
The adjoiner at feeder connection end and air-out passage arrival end, and by controlling motor driving the first switching air door switching position.
In order to assign the heating function of product, outdoor side chamber is equipped with electric heating installation 600, and the side wall of babinet is equipped with bathroom
Air-out pipe connection 114, bathroom return air take over 115, the outer air-supply adapter of bathroom air-out pipe connection adjacent chamber, outside bathroom return air take over communication chamber
The air inlet of breeze fan, the air outlet of the outer breeze fan of bathroom air-out pipe connection communication chamber, electric heating installation are located at bathroom outlet air
It takes between the air outlet of outdoor breeze fan, is equipped with for outside control room between outdoor air-supply adapter and bathroom air-out pipe connection
The second switching air door 601 that air-supply adapter, bathroom air-out pipe connection turn off or on.Second switching air door closes outdoor air-supply adapter
When, the air outlet of outdoor breeze fan is connected to bathroom air-out pipe connection, is realized to Bathroom Air circulating-heating；Second switching air door
When closing bathroom air-out pipe connection, the air outlet of outdoor breeze fan is connected to outdoor air-supply adapter, room air is discharged outdoor.
By controlling motor driving the second switching air door switching position.
Specifically, as shown in figure 4, electric heating installation 600 includes holder 602, is set on holder positioned at bathroom air-out pipe connection
Electric heater 603 between the air outlet of outdoor breeze fan, the second switching air door are assemblied on holder.Bathroom return air is taken over
The outlet end of neighbouring bypass passageways is equipped on holder for controlling bathroom return air take over 115, bypass passageways turn off or on
Third switches air door 604.Bypass passageways 112 are closed by third switching air door 604 in bathroom heating, bathroom aerating pattern, are beaten
Bathroom return air take over 115 is opened, Bathroom Air is made to enter box house, Bathroom Air sends bathroom back to again by heating when taking dim, changes
Pass through outdoor 104 discharge of air inlet take over outdoor when gas；In bypass mode, bypass passageways 112 are opened by third switching air door 604
Bathroom return air take over 115 is simultaneously closed off, Bathroom Air is prevented to enter in babinet.
The product may operate in following several modes：
1. complete-hot fresh air pattern
