Description
Technical field
The present invention relates to refrigerator technical field, more specifically, relate to a kind of air channel structure and a kind of refrigerator.
Background technology
At present, the air channel of refrigerator generally adopts the mode of back and top supplying air, as depicted in figs. 1 and 2, the air duct at top 11 of refrigerator 1 is main at the top of refrigerator 1 and near backboard Lateral supply, but, the air-flow 10 that air duct at top 11 is sent does not cover the whole top of refrigerator 1, but concentrate on the centre position at the top of refrigerator 1, thus form dead space 12, simultaneously, dead space 12 can cause assembling moisture at the top of refrigerator 1 and door seal place, thus easily produces condensation at the top of refrigerator 1 and door seal place.
Therefore, how to make air-flow can cover the whole top of refrigerator, avoid occurring dead space, thus prevent from producing condensation near the top of refrigerator and door seal, become problem demanding prompt solution.
Summary of the invention
The present invention is intended at least to solve one of technical problem existed in prior art.
For this reason, the object of the invention is to, a kind of air channel structure and a kind of refrigerator are provided, by arranging the air duct at top covering refrigerator top at the top of refrigerator, and make this air duct at top have the air duct at top of multiple exhaust vent, make air-flow can cover the whole top of refrigerator, avoid occurring dead space at the top of refrigerator and door seal place, because air-flow can take away moisture, thus prevent moisture from depositing, and then avoid occurring condensation or frosting near the top of refrigerator and door seal, extend the service life of refrigerator further.
For achieving the above object, the invention provides a kind of air channel structure, comprising: air duct at top, be arranged on the top of refrigerator, fit with the madial wall at described top, and connect with the vertical air channel of described refrigerator, and the door seal of the two ends of described air duct at top and described refrigerator is close to.
Air channel structure provided by the invention, by arranging the air duct at top with multiple exhaust vent at the top of refrigerator, and the door seal of the two ends of air duct at top and refrigerator is close to, the air-flow then making air duct at top send can cover the whole top of refrigerator, avoid occurring dead space at the top of refrigerator and door seal place, because air-flow can take away moisture, prevent moisture from assembling at the top of refrigerator and door seal place, thus avoid refrigerator inside to occur condensation or frosting, extend the service life of refrigerator further.
In addition, the air channel structure provided according to the above embodiment of the present invention also has following additional technical feature:
According to one embodiment of present invention, described air duct at top is horizontal duct.
Air duct at top horizontal direction is arranged at the top of refrigerator, the path that air-flow is circulated in air duct at top is straight line, air-flow is avoided to be hindered when circulating, thus ensure that the speed of air-flow when air duct at top flows out, and then the moisture near guarantee door seal can be taken away by air-flow rapidly, reaches the object preventing condensation or frosting near door seal.
According to one embodiment of present invention, the two ends of described air duct at top are provided with horizontal air outlet.
Because the both sides in door seal all occur condensation or frosting, so be all provided with horizontal air outlet at the two ends of air duct at top, make the air-flow flowed out from horizontal air outlet can through the both sides of refrigerator door seal, thus the moisture of the both sides of door seal can be taken away by air-flow, and then door seal local is avoided to occur condensation or frosting.
According to one embodiment of present invention, the cross section of described horizontal air outlet is inclined plane.
When air-flow is sent from horizontal air outlet, cross section due to horizontal air outlet is inclined plane, and be downward inclined plane, thus after guaranteeing that air-flow flows out from level, flow direction is all downward, when avoiding air-flow runout level air outlet, the flow direction of a part of air-flow is upwards, and the flow direction of another part air-flow is downward and reduce the effect of anti-door seal frosting.
According to one embodiment of present invention, the length of the upper side of described horizontal air outlet is greater than the length of the downside of described horizontal air outlet.
When air-flow is sent from horizontal air outlet, because the length of the upper side of horizontal air outlet is longer than the length of the downside of horizontal air outlet, make the flow direction of air-flow for from top to bottom, thus make air-flow take away moisture near door seal, and then avoid door seal and occur condensation or frosting.
According to one embodiment of present invention, the sidewall of described air duct at top is provided with multiple exhaust vent.
The sidewall of air duct at top is provided with multiple exhaust vent, make air-flow can cover the whole top of refrigerator by air outlet, air-flow is avoided too to concentrate on the centre position at the top of refrigerator, thus avoid occurring dead space, make the air-flow flowed out from air duct at top can take away moisture near the top of refrigerator and door seal, thus prevent moisture from depositing, and then avoid occurring condensation or frosting near the top of refrigerator and door seal, extend the service life of refrigerator further.
According to one embodiment of present invention, the dense degree of described multiple exhaust vent is increased gradually by center to the described door seal in described vertical air channel.
Because the position nearer with door seal more easily occurs condensation, so the quantity of the air outlet nearer with door seal is more, make near door seal more with the air flow rate at the top of refrigerator, because air-flow can take away moisture, thus effectively prevent from occurring condensation with the top of refrigerator due to moisture alluvial near door seal, and occur that at refrigerator rear portion the probability of condensation is very little, so the negligible amounts of the air outlet that the air duct at top nearer with refrigerator rear portion is arranged, thus distribute the flow of air-flow rationally and effectively, to reach the object preventing condensation.
According to one embodiment of present invention, described vertical air channel is arranged on the backboard of described refrigerator.
According to one embodiment of present invention, the sidewall in described vertical air channel arranges multiple vertical air outlet.
The diverse location of the sidewall in vertical air channel arranges multiple vertical air outlet, can be flowed out by multiple vertical air outlet for malleation air-flow, because the flow direction of malleation air-flow in vertical air channel is from the bottom to top, so vertically air outlet is arranged on the position of the differing heights in vertical air channel, wherein, the quantity of vertical air outlet can be determined the real-time requirement of refrigerator according to user.
According to the invention allows for a kind of refrigerator comprised according to any one of technique scheme.
In the present invention, by arranging the air duct at top with multiple exhaust vent at the top of refrigerator, and the door seal of the two ends of air duct at top and refrigerator is close to, thus make air-flow can cover the whole top of refrigerator, avoid occurring dead space at the top of refrigerator and door seal place, because air-flow can take away moisture, thus prevent moisture from depositing, and then avoid occurring condensation or frosting near the top of refrigerator and door seal, extend the service life of refrigerator further.
