The design feature of the pressure balancing structure of direct cooling refrigerator refrigerating chamber of the present utility model is also:
Communication apparatus comprises: refrigeration linker, freezing linker and communicating pipe; In the refrigerating chamber porch of path, refrigeration linker is set; In the exit of the refrigerating chamber of path, freezing linker is set; Communicating pipe is provided with between refrigeration linker and freezing linker; Sorbing material is provided with in communicating pipe.
Ventilating mediums is respectively arranged with in the refrigeration porch of linker and the exit of freezing linker.
Sorbing material can be active carbon, NACF or other porous masses.
Ventilating mediums can be ventilated membrane, silk screen, or check valve.
Between the refrigeration outer edge of linker porch and refrigerating chamber casing and be respectively arranged with the sealing gasket of anti-gas-leak between the outer edge in freezing linker exit and refrigerating chamber casing.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model solves refrigerating chamber to open the door the problem of requiring great effort by increasing communication apparatus between direct cooling refrigerator refrigerating chamber and refrigerating chamber, refrigerating chamber back has drainpipe, refrigerating chamber and external atmosphere pressure can be made to be consistent by drainpipe, and refrigerating chamber reaches consistent with refrigerating chamber pressure by communication apparatus, thus the principle utilizing air automatically to regulate, outside air is made to enter into refrigerating chamber by refrigerating chamber, reach refrigerating chamber air pressure to balance with extraneous, it can thus be appreciated that, the utility model makes refrigerating chamber air pressure can balance with ambient pressure on the one hand, be easy to open the door, on the other hand, air from the external world by after drainpipe to refrigerating chamber, air can drop to refrigerated storage temperature by environment temperature, freezer temperature can not be caused to fluctuate widely after entering into refrigerating chamber by communication apparatus again, energy-saving and cost-reducing, reduce costs.
2, the utility model effectively can prevent between difference between room by arranging insulation sorbing material in communicating pipe food taint of odour, prevents freezer temperature to fluctuate excessive.
3, the utility model can effectively prevent foreign material or impurity in refrigerating box from blocking communication apparatus by being provided with ventilating mediums in refrigeration linker and freezing linker.

Detailed description of the invention
In the present embodiment, as shown in figures 1 and 3, direct cooling refrigerator comprises refrigerating chamber 1 and refrigerating chamber 3, or has other rooms; The drainpipe 4 be communicated with ambient atmosphere is provided with in refrigerating chamber 1; For discharging defrosting water or the condensed water of refrigerating chamber 1; Refrigerating chamber 1 and extraneous pressure balancing structure is formed with drainpipe 4;
A pressure balancing structure for direct cooling refrigerator refrigerating chamber, is perforate between the foaming layer and the foaming layer of refrigerating chamber 3 of refrigerating chamber 1, arranges one with refrigerating chamber 1 for entrance, take refrigerating chamber 3 as the path of outlet; And communication apparatus is provided with in path, form the pressure balancing structure between refrigerating chamber 1 and refrigerating chamber 3 with communication apparatus, thus make refrigerating chamber 3 and extraneous mineralization pressure balanced structure.As shown in Figure 3, communication apparatus can optional position in the foaming layer 5 in the middle of refrigerating chamber 1 with refrigerating chamber 3, also can be communicated with arbitrarily the position of room between two as shown in Figure 1 in refrigerator back foaming layer.
Specifically, as shown in figures 1 and 3, communication apparatus comprises: refrigeration linker 2a, freezing linker 2b and communicating pipe 6; Refrigeration linker 2a is set in refrigerating chamber 1 porch of path; In the exit of the refrigerating chamber 3 of path, freezing linker 2b is set; Between refrigeration linker 2a and freezing linker 2b, be provided with communicating pipe 6, and be imbedded in communicating pipe in foam box layer 5; Sorbing material 8 is provided with in communicating pipe 6; In concrete enforcement, sorbing material 8 can be active carbon, NACF or other porous masses.
As shown in Figure 2 and Figure 4, ventilating mediums 7 is respectively arranged with in the porch of refrigeration linker 2a and the exit of freezing linker 2b; In concrete enforcement, ventilating mediums 7 can be ventilated membrane, silk screen, or check valve.
Between the refrigeration outer edge of linker 2a porch and refrigerating chamber 1 casing and be respectively arranged with the sealing gasket 9 of anti-gas-leak between the outer edge in freezing linker 2b exit and refrigerating chamber 3 casing;
Operation principle of the present utility model is:
When the air pressure of refrigerating chamber 1 is consistent with ambient pressure, refrigerating chamber 3 is as a confined space, when opening after refrigerating chamber door shuts again, outside air enters in refrigerating chamber 3, because temperature in refrigerating chamber 3 is at about-20 DEG C, outside air rapid cooling causes case internal gas pressure to diminish and lower than external atmosphere pressure.Because refrigerating chamber 1 and refrigerating chamber 3 exist draught head, and cause air to enter into refrigerating chamber 1 from drainpipe 4 entering into refrigerating chamber 3 by communication apparatus again.Ventilating mediums 7 in refrigeration linker 2a can make air freely pass through, and plays the effect sealing packing material 8 in communicating pipe 6 simultaneously.Similar in the effect of the ventilating mediums 7 in freezing linker 2b and refrigeration linker 2a.Because the food species stored in refrigerating chamber 1 is different from refrigerating chamber 3, air enters into refrigerating chamber 3 easily taint of odour from refrigerating chamber 1, the sorbing material 8 of therefore filling in communicating pipe 6 can effectively remove the peculiar smell being entered into refrigerating chamber 3 air by refrigerating chamber 1, Avoid Tainting, can also ensure that the temperature of refrigerating chamber 3 can not produce great fluctuation process.
