Be provided with the cold air guider 360 that is used for being connected cold air path 350 and cold air path 120 between described cold air path 350 and the cold air path 120.More particularly, described cold air guider 360 to a certain degree forms to lower recess from the left-hand end of dividing plate 110, the bottom surface of cold air guider 360 connects the upper end of cold air path 350, and the left-hand end of cold air guider 360 connects the lower end of cold air path 120 respectively.
Described cold air guider 360 comprise the air feed guider 360 that is used for guiding to ice-making compartment 220 cool-air feeds ' and be used for guiding the exhaust guider 360 of the cold air of discharging from ice-making compartment 220 ".More particularly, the guiding division portion 362 about the central part of described cold air guider 360 is formed with and crosses, with this guiding division portion 362 be benchmark in the wings with the place ahead be formed with respectively air feed guider 360 ' and exhaust guider 360 ".
Described air feed guider 360 ' left-hand end connect air supply channel 120 ', described exhaust guider 360 " left-hand end connect exhaust passage 120 ".The cold air path 350 and the cold air path 120 of described dividing plate 110 are interconnected by cold air guider 360.
Described cold air guider 360 is distributed by cold air and cover 370 and hide, and cold air distributes that to cover 370 shape and size thereof corresponding with cold air guider 360, and the cold air distribution is covered 370 and is removably mounted on the dividing plate 110.More particularly, described cold air distribute cover 370 comprise corresponding to air feed guider 360 ' shape and cover air feed guider 360 ' on air feed cap 370 ' and corresponding to the exhaust cap 370 on the exhaust guider 360 " shape and cover " at exhaust guider 360 ".
In addition, described cold air distribute cover 370 above be provided with heater 380.More particularly, the cold air on the described dividing plate 110 distribute cover 370 above be provided with heater 380.
Described heater 380 is used for making the base plate surface temperature of refrigerating chamber 200 to keep proper level.More particularly, the upper surface of described dividing plate 110 forms the base plate face of refrigerating chamber 200, owing to flow in the effect of the cold air in the cold air path 350, the temperature of the base plate face of refrigerating chamber 200 is lower than the temperature of refrigerating chamber 200 inner other parts.Therefore, need to improve the temperature of refrigerating chamber 200 base plate faces by heater 380.
Described heater 380 is arranged on the top of cold air path 350, promptly be arranged on corresponding to cold air path 350 be provided with the pairing dividing plate 110 in position above.More particularly, described heater 380 be arranged on the cold air that is hiding cold air guider 360 distribute cover 370 above.
Be provided with a plurality of heating wire (not shown)s in the described heater 380, heating wire is connected with feed cable 382.In addition, a side of described heater 380 also is provided with the temperature sensor (not shown) of the base plate surface temperature that is used for detecting refrigerating chamber 200 and the power circuit control device (not shown) of the timely on/off heater 380 of temperature value that detects according to temperature sensor.
Below figure the course of work of refrigerator of the present invention is illustrated:
Connect power supply from the outside and make refrigerator begin to start, under the effect of refrigerating circulation system, described refrigerating chamber 200 and refrigerating chamber 300 reach and keep the low-temperature condition of setting.
Meanwhile, described ice-making compartment 220 begins to make ice cube.Described ice-making compartment 220 is to utilize the part of the cold air that supplies to 300 li of refrigerating chambers to make ice cube.More particularly, the evaporimeter (not shown) that is arranged on refrigerating chamber 300 rear sides absorbs outside heat makes inner refrigerant evaporation, the evaporimeter ambient air formation cold air that is cooled, and with the inside of cool-air feed to refrigerating chamber 300.
A part that supplies to the cold air of refrigerating chamber 300 inside supplies to ice-making compartment 220 by cool-air supplier 340.More particularly, the cold air of discharging upward from cool-air supplier 340 is by in the cold air path 350 and air supply channel 120 ' inflow ice-making compartment 220 that are formed at dividing plate 110 inside.
More particularly, the cold air of supplying with by cool-air supplier 340 by air feed path 350 ' arrivals air feed guider 360 ', follow by air supply channel 120 ' flow in the ice-making compartment 220.Ice cube is made by cold air in inside at ice-making compartment 220.
Then, after entering cold air temperature that ice-making compartment 220 is used to make ice cube and rising relatively, " be back to refrigerating chamber 300 by exhaust passage 120.More particularly, the cold air that flow into body 100 of refrigerating-chamber door exhaust outlet 232 and the body air inlet 124 by ice-making compartment 220 " is back to the rear side of refrigerating chamber 300 by exhaust passage 120.
More particularly, the cold air of discharging from ice-making compartment 220 " is drawn towards the below and arrives exhaust guider 360 " by exhaust passage 120, and then " downside that is drawn towards dividing plate 110 flow into refrigerating chamber 300 by exhaust channel 350.And described cold air by after the cooling of evaporimeter (not shown), supplies to ice-making compartment 220 by above-mentioned path again again.
In addition, described heater 380 is switched on/disconnects according to the temperature of refrigerating chamber 200 base plate faces.More particularly, the temperature value of base plate face that detects refrigerating chamber 200 when the temperature sensor (not shown) is during less than the lower limit of design temperature, power circuit control device (not shown) just makes heater 380 connect power supply, heater 380 is started working, and the temperature of the base plate face of refrigerating chamber 200 is risen; The temperature value of base plate face that detects refrigerating chamber 200 when the temperature sensor (not shown) is during greater than the higher limit of design temperature, power circuit control device (not shown) just makes heater 380 deenergizations, heater 380 quits work, and the temperature of the base plate face of refrigerating chamber 200 is descended.
It is worthy of note that protection scope of the present invention is not limited to the above-mentioned specific embodiment, according to basic fundamental design of the present invention, those skilled in the art need not can associate some other embodiment through creative work.
For example, in the above-mentioned specific embodiment, described heater 380 be arranged on cold air distribute cover 370 above, but this only is a kind of embodiment, described heater 380 also can be arranged on other positions of refrigerating chamber 200 base plate faces.
In other words, so long as the position that may cause freezing owing to the cold air that flows in dividing plate 110 inside makes the temperature of refrigerating chamber 200 base plate faces be lower than environment temperature can be provided with described heater 380.
