Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
Embodiment mono-
As shown in Figure 1-Figure 3, the present embodiment air duct cover board, comprises cover board body 1, on described cover board body 1, offer multiple air outlets 11, also comprise electrical heating wire 2, described electrical heating wire 2 is fixed on described cover board body 1, and the side of described air outlet 11 is distributed with described electrical heating wire 2.
Particularly, the cover board body 1 of the present embodiment air duct cover board is installed in the refrigerating chamber of air cooling type refrigerator, the surface that cover board body 1 is relative with freezer wall is inner surface, exposed surface in refrigerating chamber is outer surface, on the inner surface of cover board body 1, be provided with electrical heating wire 2, electrical heating wire 2 is distributed in the side of air outlet 11, in the time there is frosting in air outlet 11 places, electrical heating wire 2 energising heating, the heat that electrical heating wire 2 produces can melt the frost layer at air outlet 11 places timely, thereby can effectively avoid air outlet 11 to be blocked by frost layer, simultaneously, electrical heating wire 2 is in energising heating process, can also heat cover board body 1 surface, thereby avoid cover board body 1 surface to occur frosting.
The present embodiment air duct cover board, by electrical heating wire is set on cover board body, electrical heating wire is distributed in the side of air outlet, in the time that air outlet place forms frost layer, electrical heating wire energising can be heated air outlet, thereby melt timely and effectively the frost layer at air outlet place, avoid air outlet to be sheltered from by frost layer, realize the phenomenon of avoiding the air outlet of air duct cover board to be stopped up by frost layer and occur.
Embodiment bis-
As shown in Figure 1-Figure 3, the present embodiment air duct cover board is based on above-described embodiment one, and the bottom surface of the air outlet 11 in the present embodiment tilts and arranges down.Concrete, the bottom surface of air outlet 11 tilts to form certain gradient down, thereby by electrical heating wire 2 heating processes, the bottom surface that the frost layer formation water being melted tilts via air outlet 11 can flow out smoothly, meanwhile, because cold air is heavier, the form that the bottom surface of air outlet 11 is set to down is more conducive to blowing out of wind, and water can flow out from the bottom surface of air outlet 11 smoothly under wind action.Wherein, the bottom surface of air outlet 11 and the angle of horizontal plane are 10 °-15 °, for example: the angle that bottom surface and horizontal plane can be set is 11.3 °, by the suitable gradient is set, guaranteeing that cold wind and defrosting water can be along towards in the smooth and easy outflows of bottom surface having a down dip, also facilitate cover board body 1 injection mo(u)lding, avoid cannot carrying out reverse mould because inclination angle is much, reduced difficulty of processing.Wherein, be also provided with guiding gutter 3 on the bottom surface of air outlet 11, guiding gutter 3 is connected with the bottom surface of air outlet 11, and guiding gutter 3 can carry out water conservancy diversion to the water flowing out from air outlet 11, thereby avoids the water that flows out from the air outlet 11 surperficial sinuous flow at cover board body 1.And between the outlet of the described guiding gutter 3 on air outlet 11, be connected with diversion column 31 described in each in same row.Concrete, the water that can conflux in each guiding gutter 3 by diversion column 31, diversion column 31 can effectively drain into defrosting water the bottom of cover board body 1, preferred, the bottom of cover board body 1 is provided with collecting tank 4, and described diversion column 31 is inserted in described collecting tank 4.Water flows downward along diversion column 31, and finally flows in collecting tank 4 and accumulate, and meanwhile, the defrosting water collecting in collecting tank 4 can also play the effect of refrigeration plant inside being played to humidification.
Further, electrical heating wire 2 is embedded on the inner surface of described cover board body 1, and air outlet 11 correspondences are provided with blinker 5, and described blinker 5 is slidably connected on the inner surface of described cover board body 1.Concrete, because electrical heating wire 2 is inlayed on cover board body 1, the inner surface entirety of cover board body 1 is smooth planar structure, thereby can increase blinker 5 and adjust the aperture in air port 11, blinker 5 can not be subject to the interference of electrical heating wire 2 in sliding process, can slide smoothly.And the aperture size of air outlet 11 regulates by blinker 5, on the one hand by regulating the blinker 5 of diverse location place air outlet 11 correspondences to adjust the aperture in air port 11, meet the adjusting of the interior temperature homogeneity of casing of refrigeration plant.
Wherein, the arrangement mode of electrical heating wire 2 on cover board body 1 can have multiple formation, for example: the both sides up and down that are arranged in same row's described air outlet 11 are distributed with described electrical heating wire 2, or, the left and right sides that is arranged in the described air outlet 11 of same row is distributed with described electrical heating wire 2, above-mentioned two kinds of modes all can effectively be carried out heating and melting to the frost layer at air outlet 11 places, simultaneously, because electrical heating wire 2 is arranged on the side at air outlet 11, in the time that operating personnel are assembled on cover board body 1 by electrical heating wire 2, only need the side wiring along air outlet by electrical heating wire 2, facilitate the assembling of the present embodiment air duct cover board.
