Background

An air passage is provided in the ventilating device to send outdoor air into the room and/or discharge indoor air to the outside. The air duct is usually provided with an air valve to adjust the air volume, including fully opening ventilation and fully closing ventilation. The existing air valves are mainly of two types, one type is a rotary air valve, namely, an air plate rotates around a pivot driven by a motor to adjust air volume, but the air plate cannot stay at any position due to the fact that a main shaft of the motor is required to face and bear air pressure, and the air pressure is possibly changed. The other is a movable air valve, which is easy to realize that the air plate stays at any position, but has poor sealing performance, and particularly has high air leakage rate in a completely closed ventilation state.

Detailed Description

The present invention will be described in detail below with reference to embodiments shown in the drawings. However, these embodiments are not intended to limit the present invention, and structural, methodical, or functional changes that may be made by one of ordinary skill in the art based on these embodiments are all included in the scope of the present invention.

As shown in fig. 1, in an embodiment of the present invention, the ventilation apparatus 100 may be installed in a space above an indoor ceiling. The ventilating device 100 may be a total heat type ventilating device including a case, an air supply inlet 101 for allowing outdoor air to be introduced, an air discharge outlet 102 for allowing indoor air to be discharged, which are provided at one side of the case, and an air discharge inlet 103 for allowing indoor air to be introduced, and an air supply outlet 104 for allowing outdoor air to be discharged, which are provided at the other side of the case. An air passage 105 is provided in the housing, and the air passage 105 may be an air supply passage defined between the air supply inlet 101 and the air supply outlet 104 for sending outside air from the outside to the inside, or an air discharge passage defined between the air discharge inlet 103 and the air discharge outlet 102 for sending indoor air from the inside to the outside. A heat exchange part 106 is located at the crossing position of the air supply path and the air discharge path so that the external air introduced from the outdoor through the air supply path and the indoor air discharged from the indoor through the air discharge path are heat exchanged in a non-contact manner in the heat exchange part 106, thereby supplying the heated external air to the indoor without giving uncomfortable feeling to the user in the cold winter. The air passage 105 may be a bypass passage that does not pass through the heat exchange member 106, and may directly introduce the outside air into the room or directly discharge the inside air to the outside. In other embodiments, the ventilation device may be an air exhaust device for exhausting indoor air to the outside only, or a fresh air device for introducing outdoor air to the inside only.

As shown in fig. 2 to 5, the damper 10 is disposed across the duct 105 to regulate the air volume passing through the duct, including completely closing the duct and completely opening the duct. The damper 10 includes longitudinally extending front and

rear cover plates

11 and 12, a damper 13, and a drive device. The front cover plate 11 and the rear cover plate 12 are respectively provided with

corresponding ventilation openings

111 and 121. The rear cover 12 is snap-fitted with the front cover 11 to form a case for accommodating the damper 13 and the driving device, and defines guide rails 112 (only one of which is labeled) for guiding movement of the damper at the top and bottom within the case. In other embodiments, the rear cover plate 12 may be omitted.

The damper is closely disposed on one side surface of the front cover plate 11, and a guide post 132 (only one of which is labeled) that can be extended into the guide rail 112 protrudes from both the top and bottom thereof so as to be longitudinally translated by the driving means to adjust the ventilation area of the

ventilation openings

111, 121. The driving device is fixedly disposed on the side of the damper 13 opposite to the side where the front cover 11 is disposed, and includes a motor 14 and a gear 141 driven by the motor. The damper 13 is provided with a linear rack 131 which is engaged with the gear 141 and extends in the longitudinal direction.

The damper further comprises a seal 15 arranged between the front cover plate 11 and the damper 13. The sealing member 15 is a flat plate having openings 153 corresponding to the

ventilation openings

111 and 121. Referring to fig. 3, 4 and 5, at least two

positioning holes

1521, 1522 are disposed on the sealing member 15, and preferably, the at least two

positioning holes

1521, 1522 are distributed at diagonal positions of the sealing member 15. Correspondingly, at least two

positioning posts

112, 113 are further disposed on the side surface of the front cover plate 11, so that the sealing member 15 can be reliably positioned on the front cover plate 11 by the cooperation of the

positioning holes

1521, 1522 and the

corresponding positioning posts

112, 113. In the present embodiment, the seal member 15 includes a sponge layer 151 held (e.g., adhered) on the above-described side surface of the front cover plate 11, and a hard plastic layer 152 held on the sponge layer 151 in contact with the damper. The hard plastic layer may be made of Polyester (PET), Polyoxymethylene/Polyformaldehyde (POM), or nylon (Polyamide, PA). Preferably, when the damper 13 is moved to one longitudinal end (left or right end) of the front cover plate 11, it is disposed to at least partially overlap the seal 15.

By arranging the sealing element between the front cover plate and the air door, the sealing performance of the air valve can be effectively improved (particularly when ventilation is completely blocked), and the air leakage probability is reduced. In addition, because the air door needs to slide, the hard plastic layer is arranged at the contact position of the sealing element and the air door, so that the sliding friction force of the air door can be reduced, the air door can be conveniently moved to any position, and meanwhile, the sealing performance of the air valve is ensured.

Fig. 6 and 7 show another embodiment of the damper of the present invention, and the main difference of this embodiment from the above embodiment is that there are two

ventilation openings

211, 212 on the front cover plate 21 of the damper 20, and correspondingly, there are two ventilation openings (not shown) on the rear cover plate 22, and two

openings

253, 254 on the damper 25. In the present embodiment, the damper 25 completely covers one side surface of the front cover 21, which also includes the sponge layer 251 and the hard plastic layer held on the sponge layer 251. The damper 20 of this configuration can be used as a changeover valve in which one of the vents is closed when the damper is moved to either longitudinal end of the front cover plate, thereby achieving free changeover between the two vents.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
