The specific embodiment
In conjunction with the accompanying drawings the utility model is described in further detail below by the specific embodiment.
Embodiment one:
As shown in Figure 1, be the front view of wind cooling refrigerator embodiment one of the present utility model, wherein, the refrigerating chamber of wind cooling refrigerator comprises evaporimeter 11, is enclosed in evaporimeter 11 insulating foam layer 12 (i.e. part shown in the cross spider among the figure), return air inlet 14 on every side.Return air and then is worn whole evaporimeter 11 from evaporimeter 11 bottom streams and is got back to fan from the air channel 10 from top to down.Embodiment one is provided with recess 13 at a side and insulating foam layer 12 connecting places of evaporimeter 11, and the bottom of recess 13 is towards insulating foam layer 12, recess 13 be shaped as from the bottom of evaporimeter 11 to its top narrow down gradually stepped; This paper claims recess 13 to be " household freezer courage return air inlet ".As can be seen, after having increased household freezer courage return air inlet 13, return air inlet 14 surrounding spaces obviously strengthen, even the close return air inlet 14 position frostings of evaporimeter 11 like this, also be difficult for blocking return air inlet, so this embodiment one reduces the stifled defective of general refrigerator return air inlet frost by strengthening return air inlet space on every side.
Embodiment two:
Because return air is from the air channel 10 from top to down, and then wear whole evaporimeter from evaporimeter 11 bottom streams and get back to fan, walk around evaporimeter 11 for pre-anti-air-return and directly flow back to fan by household freezer courage return air inlet 13, the utility model also provides on the basis of embodiment one implements two, as shown in Figure 2, also design has deep bead 151 in this embodiment two, and deep bead 151 links to each other with the port part of return air inlet 14, and extend to the port part of return air inlet 14, and partial occlusion is lived return air inlet 14.Angle between the bottom surface of deep bead 151 and evaporimeter 11 is an acute angle; This acute angle is 30 degree among a kind of embodiment.
In an embodiment, refrigerating chamber also is provided with drip tray 15, is positioned at the below of evaporimeter 11, is used to connect defrost water, and this paper claims this drip tray to be " defrost drip tray "; Deep bead 151 is arranged on the defrost drip tray 15, shown in Fig. 3-5.By the guiding of the deep bead on the defrost drip tray 15 151, guarantee to get back to fan after bottom that return air passes evaporimeter 11 as much as possible and evaporimeter 11 exchanges, cold is exchanged fully carry out; In addition, because this deep bead 151 is positioned at return air inlet 14 ports top, and with the angle of evaporimeter 11 bottom surfaces be sharp angle, this sharp angle is 30 degree angles among the embodiment, make the direction of defrost water only may flow down toward the drip tray direction, therefore this deep bead 151 also has the guide effect of defrost water, prevents that defrost water from flowing to return air inlet and freeze.
The utility model also provides a kind of refrigerating chamber air return system, described refrigerating chamber is provided with evaporimeter, return air inlet, is enclosed in described evaporimeter insulating foam layer on every side, the bottom of described evaporimeter and described insulating foam layer connecting place are provided with recess, and the bottom of described recess is towards described insulating foam layer.Described recess be shaped as from the bottom of described evaporimeter to the top of described evaporimeter narrow down gradually stepped.Described refrigerating chamber also is provided with deep bead, and described deep bead links to each other with the port part of described return air inlet, and described deep bead extends the described return air inlet of partial occlusion to the port part of described return air inlet.Described refrigerating chamber also is provided with drip tray, and described drip tray is positioned at the below of described evaporimeter, is used to connect defrost water; Described deep bead is arranged on the described drip tray.Angle between the bottom surface of described deep bead and described evaporimeter is an acute angle.This paper refrigerating chamber return air inlet system embodiment all adopts identical design with previous embodiment one and embodiment two, repeats no more herein.
Therefore the utility model wind cooling refrigerator is used by case courage return air inlet and defrost drip tray, has prevented wind cooling refrigerator return air inlet frost stifled, and provides guide effect for defrost water and return.
Above content be in conjunction with concrete embodiment to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
