Detailed description of the invention
Referring to figs. 1 through Fig. 7, the utility model fresh air ventilator embodiment is described further.
A kind of fresh air ventilator, comprise housing 1, described housing 1 side is provided with the first air inlet 21 entered for extraneous new wind, second air outlet of indoor exhaust wind, the opposite side of described housing 1 is provided with the second air inlet entered for internal gas, supplied gas enters the first indoor air outlet 22, heat exchange chip 12 is also provided with in described housing 1, described first air inlet 21 is communicated with by heat exchange chip 12 with the first air outlet 22, described second air inlet 3231 is communicated with by heat exchange chip 12 with the second air outlet, described first air inlet 21 and the second air inlet 3231 are equipped with ventilating fan 64, described first air outlet 22 is provided with the first fan 51, described second air outlet is provided with the second fan 52, rotating shaft 53 is provided with between described first fan 51 and the second fan 52, described first fan 51 and the second fan 52 are linked by rotating shaft 53.
Preferably, described first air outlet 22 is corresponding with the second air outlet position for the present embodiment, and the first air inlet 21 is corresponding with the first air inlet 21 position, and distribution as shown in Figure 2,3, 4.
Preferably, described heat exchange chip 12 places centre position in the enclosure to the present embodiment, and shell comprises criss-cross baffle plate 11, and be distributed in heat exchange chip 12 surrounding, baffle plate 11 is wholely set with shell, and concrete structure as shown in Figure 2,3; Heat exchange chip 12 comprises four layers of monomer heat exchange chip 12 and is formed by stacking exchange, monomer heat exchange chip 12 comprises framework and is arranged on the heat exchange membranes on framework, two-layer monomer heat exchange chip 12 forms the first slope air course, supplies the newly distinguished and admirable to the first air outlet 22 of the first air inlet 21; Two-layer monomer heat exchange chip 12 forms the second slope air course in addition, and the indoor exhaust wind for the second air inlet 3231 flows to the second air outlet; Described first slope air course and the second slope air course are and are interspersed, and be provided with heat exchange membranes between the two, carry out heat exchange fully for new wind and air draft, utilize heat exchange chip 12 just can ensure that air draft and new wind only can carry out heat exchange with the structure in shell like this, and can not mutually mix.
Preferably, described rotating shaft 53, through the baffle plate 11 on described shell, is provided with two fixed mounts 57 of fixed rotating shaft 53, has bearing to arrange, ensure that the rotation that rotating shaft 53 can be stable between fixed mount 57 and rotating shaft 53 the present embodiment in shell.
By adopting technique scheme, as long as the first air outlet 22 or the second air outlet there are the discharge of air, just the rotation of the first fan 51 or the second fan 52 can be driven, as long as there is the rotation of a fan just can drive another rotation in both, both be in synchronous operated, this ensure that can not single air outlet excessive thus cause one-way airflow unbalanced, cause heat exchange insufficient, heat has larger loss; Once certain air outlet is comparatively large, two fan run-in synchronisms, another fan can offset part energy, produces certain pull of vacuum, increases the dynamic wind speed that comparatively flows slowly, and reduces the wind speed of very fast flowing, ensures the equilibrium of ventilating.
Described first fan 51 is contrary with the blade rotation direction of the second fan 52.
By adopting technique scheme, because two fans are all that same rotating shaft 53 connects, therefore the first fan 51 is identical with the rotation direction of the second fan 52, because the air-out directions of two are different, make two fans can air draft normally so the first fan 51 is contrary with the blade rotation direction of the second fan 52, ensure that the exploitativeness of fresh air ventilator.
Described rotating shaft 53 is provided with ratchet 54 assembly for rotating shaft 53 single direction rotation.
Described ratchet 54 assembly comprises ratchet 54, retainer ring 56, described retainer ring 56 is fixedly connected with shell, described ratchet 54 and rotating shaft 53, retainer ring 56 are concentric, described ratchet 54 is fixedly connected with rotating shaft 53, and described ratchet 54 is positioned at described retainer ring 56, be provided with fixture block 55 in described retainer ring 56, described fixture block 55 one end and described ratchet 54 clamping, the other end and described retainer ring 56 inwall of described fixture block 55 are hinged.
Preferably, described retainer ring 56 is embedded on the baffle plate 11 of shell the present embodiment, and described fixture block 55 one end is hinged on the top of described retainer ring 56, the other end is because gravity is attached to ratchet 54 surface, with ratchet, ensure that ratchet 54 and the single direction rotation of rotating shaft 53, can not reverse.
By adopting technique scheme, utilizing ratchet 54, ensure that the single direction rotation of two fans, fan only can be made to rotate toward the direction of air draft, prevent because extraneous wind is excessive, and occur that the phenomenon of pouring in down a chimney occurs, adds the practicality of fresh air ventilator.
