In embodiments more of the present utility model, the air channel 30 of refrigerator 100 can comprise the first air return section 31, second air return section 32, heat exchanging segment 33 and air supply section 34.Heat exchanging segment 33 also can be called as cooling chamber, to install cooler 40 within it.The heat exchanging segment 33 in air channel 30 can have the first import, the second import and outlet, and cooler 40 is positioned at heat exchanging segment 33.And along the flow direction of gas in heat exchanging segment 33, the first inlet communication is to the upstream of cooler 40, and the second inlet communication is to the downstream of cooler 40.First air return section 31 can be communicated to the first import and the second import, and has the one or more imports being communicated to indoor between described one or more storing respectively.Such as, the first air return section 31 can be communicated with refrigerating chamber 21.Second air return section 32 can be communicated to the first import, and has the one or more imports being communicated to room between all the other storings respectively.Such as, the second air return section 32 can be communicated with refrigerating chamber 22.Air supply section 34 can be communicated to the outlet of heat exchanging segment 33, and has at least one that be communicated with room between at least one storing respectively and export.Namely air supply section 34 can have the one or more outlets being communicated to indoor between described one or more storing respectively.And air supply section 34 also has the another one or other multiple outlet that are communicated with room between all the other storings respectively.Such as, air supply section 34 can be communicated with refrigerating chamber 21 with refrigerating chamber 22 simultaneously.
In embodiments more of the present utility model, as shown in Figure 1, the heat exchanging segment 33 in air channel 30 can be arranged at the rear portion of refrigerating chamber 22, first import is arranged at the bottom of heat exchanging segment 33, second import is arranged at the top of heat exchanging segment 33, to reduce the volume of refrigerator 100, makes refrigerator 100 compact conformation.Refrigerator 100 also can comprise blower fan 70, is arranged at the exit of heat exchanging segment 33, to improve air-supply efficiency.Further, refrigerator 100 also can comprise the defrost sensor be arranged on cooler 40 and the frost removal 80 be installed on below cooler 40, to defrost to cooler 40.
In embodiments more of the present utility model, in order to realize the several functions of refrigerator 100, refrigerator 100 also can comprise the first opening and closing device 50 and the second opening and closing device 60.First opening and closing device 50 is arranged in the first air return section 31, be configured to controllably open or close, to allow when opening to flow through cooler 40 from the whole of gas indoor between described one or more storing, between allowing when closing from described one or more storing, indoor the whole of gas walk around cooler 40.Preferably, the first opening and closing device 50 can comprise the flabellum 51 for blocking path.In some substituting embodiments, refrigerator 100 also can comprise the 3rd opening and closing device, to replace the first opening and closing device 50 being positioned at the first air return section 31,3rd opening and closing device can be configured to adjust the ratio of the gas entering the first import and the second import, also can make all enter the first import from gas indoor between described one or more storing or all enter the second import.
Second opening and closing device 60 of refrigerator 100 can be arranged in air supply section 34, be configured to controllably open or close, indoor to allow the gas in air channel 30 to enter between described one or more storing when opening, stop the gas in air channel 30 to enter room between described one or more storing when closing.
This refrigerator 100 according to the opening and closing combination between the first opening and closing device 50, second opening and closing device 60, can control the flowing of gas in air channel 30, to realize several functions.Particularly, can refrigerating chamber 21 temperature sensor be set in refrigerating chamber 21, refrigerating chamber 22 temperature sensor is set in refrigerating chamber 22, refrigerator 100 can according to refrigerating chamber 21 temperature sensor detect temperature determination refrigerating chamber 21 the need of refrigeration, and according to refrigerating chamber 22 temperature sensor detect temperature determination refrigerating chamber 22 the need of refrigeration.
In the utility model embodiment, when refrigerator 100 normally works, cooler 40 freezes, when refrigerating chamber 22 needs refrigeration, by blower fan 70, cold wind is blowed to refrigerating chamber 22 via the air supply section 34 in air channel 30 inner, controlled the cryogenic temperature of refrigerating chamber 22 by refrigerating chamber 22 temperature sensor, after reaching target cryogenic temperature, blower fan 70 cuts out, and refrigerator 100 stops refrigeration.When refrigerating chamber 21 needs refrigeration, open the second opening and closing device 60, and it is inner by blower fan 70, cold wind to be blowed to refrigerating chamber 21 via the air supply section 34 in air channel 30, is controlled the cryogenic temperature of refrigerating chamber 21, by refrigerating chamber 21 temperature sensor after reaching target cryogenic temperature, close the second opening and closing device 60, if now refrigerating chamber 22 needs refrigeration, then blower fan 70 works on, if now refrigerating chamber 22 also reaches target cryogenic temperature, then blower fan 70 also cuts out, and refrigeration terminates.
Normally work at refrigerator 100, when cooler 40 cools and blower fan 70 operates, the gas in refrigerating chamber 22 can return to cooler 40 place via second air return section 32 in air channel 30, after carrying out heat exchange with cooler 40, continue circularly cooling.
Normally work at refrigerator 100, when cooler 40 cools and blower fan 70 operates, the first opening and closing device 50 can be in opening, makes the first air return section 31 and heat exchanging segment 33 via the first inlet communication, the second import between the first air return section 31 and heat exchanging segment 33 is disconnected.Gas in refrigerating chamber 21 can return to cooler 40 place via the first air return section 31 and the first import, make heat exchange abundant, the gas temperature blowing to refrigerating chamber 21 is lower, fast cooling for refrigerating chamber 21 is more favourable, but what bring is that water loss in refrigerating chamber 21 is serious simultaneously, the defrosting of cooler 40 is frequent.
Normally work at refrigerator 100, when cooler 40 cools and blower fan 70 operates, the first opening and closing device 50 can be in closed condition, makes the first air return section 31 and heat exchanging segment 33 via the second inlet communication, the first import between the first air return section 31 and heat exchanging segment 33 is disconnected.Gas in refrigerating chamber 21 can enter the downstream of heat exchanging segment 33 intercooler 40 (as in Fig. 1 via the first air return section 31 and the second import, the top of cooler 40), to mix with the gas cooled through subcooler 40, then enter in refrigerating chamber 21.Avoid the gas in refrigerating chamber 21 to contact with evaporimeter cause frosting and refrigerate loss of moist.The refrigerator 100 of this embodiment, when freezing for the first time, for ease of reducing the temperature in refrigerating chamber 21 fast, can allow the first opening and closing device 50 be in the state opened, lowering the temperature to make refrigerating chamber 21 fast.After stable, the first opening and closing device 50 can be made to be in closed condition, energy-conservation and good to food fresh-keeping.
So far, those skilled in the art will recognize that, although multiple exemplary embodiment of the present utility model is illustrate and described herein detailed, but, when not departing from the utility model spirit and scope, still can directly determine or derive other modification many or amendment of meeting the utility model principle according to content disclosed in the utility model.Therefore, scope of the present utility model should be understood and regard as and cover all these other modification or amendments.
