Abstract
The invention relates to an icemaker cold air channel with evenly-distributed flow in a refrigerator. The cold air channel comprises a bottom plate; a cover plate; a cold air outlet formed by an inner air duct baffle, a middle air duct baffle and an outer air duct baffle which are mutually separated; and a cold air outlet communicating with the above cold air outlet, wherein arc surface parts of the middle air duct baffle are respectively composed of concentric arc surfaces; the radii of the concentric arc surfaces are respectively integral-multiples. According to the inventive form of the cold air channel, the equal rate of the temperature is as high as 99% in multi-sampling temperature detection, thus, the control over the ice-making time is effective, and the difference in freezing time of ice blocks is basically avoided.

Summary of the invention
Of the present inventionly be to provide a kind of flow equally distributed ice maker cold air passage.Concretely, be the approach that the cold wind in refrigerator leads to the ice machine inner space, rational cold air passage is set, so that in a limited space, obtain equally distributed as much as possible temperature field, accurately the control ice making time, play time-saving energy-saving and control accurate purpose.
By cold air passage of the present invention, can be so that the space of ice-making compartment forms awkward silence at a meeting distribution highly uniformly.
Purpose of the present invention can be achieved in the following manner, one refrigeration space is set, an ice-making compartment 2 is set in described space, retract ice making box 1 for convenience, described ice-making compartment 2 is a drawer type, described ice making box 1 is plugged on wherein, in described ice-making compartment 2 sides cold air passage is set.
Described cold air passage, comprise base plate, cover plate, interior air channel barrier, middle air channel barrier, outer air channel baffle plate form the cold wind outlet of mutual partition, the cold wind outlet that is communicated with the cold wind outlet, and the cambered surface part of described middle air channel barrier is made up of concentric circle arc plane respectively.The radius of described concentric circle arc plane is respectively integral multiple.
Connect middle air channel barrier, the adjacent successively formation of the outer air channel baffle plate cold wind outlet arranged side by side of the interior air channel barrier and the concentric circle arc plane composition of concentric circles center of circle vertical line.
In order to introduce cold wind better, middle air channel barrier is towards the final position of cold wind import, be arranged on cold wind pelvic outlet plane angle be the position of 38-46 degree.
Consider the eddy current effect near the cold wind import, the interior air channel barrier that connects concentric circles center of circle vertical line is set to the right angle of an arc transition.
Studies show that design of the present invention is not all to be effectively under described size, should, under certain size, the equally distributed effect of cold wind of the present invention should be outstanding especially, and certain size of the present invention is meant that radius r is 6-12cm.
Height in cold air passage of the present invention is 0.25-0.31r.
Adopt cold air passage form of the present invention, in the temperature detection of multi-point sampling, the identical rate of its temperature is up to 99%, like this, is effectively to the control of ice making time, and the ice cube temporal differences of freezing can not take place substantially.
Description of drawings
Fig. 1 is a cold air passage perspective view of the present invention;
Fig. 2 is the structural representation of cold air passage of the present invention;
Among the figure: detachable ice making box 1, ice-making compartment 2, air channel 3,4,5, cold wind import 6, interior air channel barrier 7, middle air channel barrier 8,9, outer air channel baffle plate 10.
The specific embodiment
The equally distributed ice maker cold air passage of a kind of flow, comprise base plate, cover plate, interior air channel barrier 7, middle air channel barrier 8,9, outer air channel baffle plate 10 forms the cold wind outlet that cuts off mutually, and the cold wind outlet that is communicated with the cold wind outlet, it is characterized in that the cambered surface part of described middle air channel barrier, form by concentric circle arc plane respectively.
