Detailed description of the invention
Referring to accompanying drawing, embodiments of the present invention are described.Fig. 1, Fig. 2 are front view and the cross-sectional side view of the refrigerator inside representing an embodiment.The top of the heat insulating box 2 of refrigerator 1 is provided with the refrigerating chamber 3 for stored refrigerated reserve.The refrigerating chamber 4 for freezen protective reserve is provided with in the below of refrigerating chamber 3.Refrigerating chamber 3 and refrigerating chamber 4 are separated by thermal wall 5.
Cold air path 10 is formed in the behind of refrigerating chamber 4.Offer flow export 14,15 on the front surface top of cold air path 10, offer return port 16 in the lower end of cold air path 10.The cooler 11 for generating cold air is provided with in cold air path 10.Above cooler 11, be provided with fan 12, below is provided with Defrost heater 13.Utilize the driving of fan 12, the air and the cooler 11 that make to flow through cold air path 10 carry out heat exchange thus generate cold air.In addition, the driving of Defrost heater 13 is utilized to defrost to cooler 11.
The isolation ward 8 be separated by separation frame 7 is formed in the bottom of refrigerating chamber 3.The receiver 8a of slide anteroposterior is provided with in isolation ward 8.On the two side 3b of refrigerating chamber 3, be set side by side with multiple setting unit 6 along the vertical direction, described setting unit 6 is for setting up the pallet (not shown) of carrying reserve.
The flow pass 20 being communicated in cold air path 10 by baffle plate 18 is provided with in the behind of refrigerating chamber 3.Flow pass 20 in the central portion setting extending longitudinally of refrigerating chamber 3 left and right directions, and is formed from the backplate 3a of refrigerating chamber 3 is outstanding.In addition, when observing from front, cooler 11 is configured on the extended line of flow pass 20.Be formed with backward channel 30 in the bottom of refrigerating chamber 3, described backward channel 30 offers return port 31 at upper surface.Backward channel 30 is connected with the cold air path 10 of cooler 11 upstream side.
Fig. 3 illustrates the A-A sectional drawing of Fig. 1.The backplate 3a of refrigerating chamber 3 is provided with the pipeline panel 21 formed by heat-barrier materials such as expanded polystyrene (EPS)s.Pipeline panel 21 is kept by the maintenance panel 23 as synthetic resin, keeps the engagement pawl (not shown) that panel 23 is arranged to engage with backplate 3a.Thus, pipeline panel 21 is installed on backplate 3a, utilizes the recessed groove being arranged on pipeline panel 21 back side to form flow pass 20.The sidewall 21a of pipeline panel 21 forms the side of flow pass 20, and offers the flow export 24 of cold air.
Flow export 24 is separately positioned between each setting unit 6 (with reference to Fig. 2).Thus, when pallet being set to the position of needs, cold air can be discharged in each region of being separated by pallet.Therefore, the reserve that pallet carries can reliably be cooled.In addition, isolation ward 8 (with reference to Fig. 1) does not arrange flow export 24.
The front surface of pipeline panel 21 is provided with the component 22 formed by the good conductor of the heat such as metal (such as stainless steel and aluminium).Component 22 engages and is installed on the groove portion 23a keeping panel 23 is arranged.Component 22 extending longitudinally is utilized to cover the front surface of flow pass 20.Thus, the cold flowing through the cold air of flow pass 20 is delivered to component 22 by pipeline panel 21, and discharges to refrigerating chamber 3.
Fig. 4 illustrates the B-B sectional drawing of Fig. 1.Backward channel 30 (with reference to Fig. 1) overlaps with the front surface of the bottom of flow pass 20, is arranged on return port 31 in isolation ward 8 (reference Fig. 1) towards upper opening.In order to prevent foreign matter from entering, return port 31 is formed with grid 31a.In addition, component 22 is entered in backward channel 30 from top by return port 31, and the cold air that backward channel 30 and the front surface along component 22 are circulated contacts.Thus, the cold flowing through the cold air of backward channel 30 is passed to component 22.
In the refrigerator 1 of said structure, when drive fan 12, the cold air generated by cooler 11 flows through cold air path 10, and is discharged to the top of refrigerating chamber 4 from flow export 14,15.The cold air being discharged to refrigerating chamber 4 circulates in refrigerating chamber 4, flows out and turn back to cooler 11 from the return port 16 of bottom.Thus, the reserve in refrigerating chamber 4 is cooled.
If open baffle plate 18, then the part flowing through the cold air of cold air path 10 is directed to flow pass 20.The cold air flowing through flow pass 20 is discharged to side as shown in arrow D1 (with reference to Fig. 3) from the flow export 24 being arranged at side.From the cold air limit that flow export 24 is discharged because deadweight declines, the backplate 3a of edge refrigerating chamber 3 circulates in the lateral direction, and forwards circulates along the sidewall 3b of refrigerating chamber 3.
Then, this cold air flows into isolation ward 8 from front, and circulation around receiver 8a also, as shown in arrow D2 (with reference to Fig. 2), is flowed out from the return port 31 of the central portion of left and right directions.The cold air flowed out from return port 31 flows through backward channel 30, and returns cooler 11.
In addition, the cold flowing through the cold air of flow pass 20 and backward channel 30 is passed to component 22, discharges as shown in arrow E (with reference to Fig. 3) in refrigerating chamber 3.
The reserve being arranged on the central portion of the left and right directions in refrigerating chamber 3 utilizes the cold discharged from component 22 to be cooled.The reserve of the both sides in refrigerating chamber 3 utilizes the cold of the cold air circulated along backplate 3a and sidewall 3b to be cooled.Thus, cold can be utilized from surrounding cold storage thing indirectly.
According to present embodiment, be provided with the component 22 as the good conductor of heat at the front surface of the flow pass 20 given prominence to from the central portion at refrigerating chamber 3 back side, be provided with flow export 24 in side.Thus, from component 22 released cold quantity, the cold air of discharging from flow export 24 is along the back side of refrigerating chamber 3 and side circulation.Therefore, reserve in refrigerating chamber 3 utilizes the cold that discharges from component 22 and is cooled along the cold of the cold air of the back side and side.Therefore, the cold air directly contacting reserve reduces, and can alleviate the drying of reserve.
In addition, because flow pass 20 is arranged on the central portion of left and right directions, so when guaranteeing the basal area of horizontal section of flow pass 20 according to flow, the asperratio of horizontal section is close to 1.Thus, reduce the pressure loss of flow pass 20, the energy-saving of refrigerator 1 can be realized.
In addition, because return port 31 is configured in the bottom of refrigerating chamber 3, flow export 24 is configured in the top of return port 31, so be directed to return port 31 from the cold air of flow export 24 discharge because conducting oneself with dignity.Therefore, the air-supply efficiency of fan 12 can be improved.
In addition, because the front surface of backward channel 30 with flow pass 20 overlaps, and the return port 31 that component 22 passes through opening upward enters in backward channel 30, so the cold flowing through the cold air of backward channel 30 is passed to component 22 and discharges to refrigerating chamber 3.Therefore, the cooling effectiveness of refrigerator 1 can be improved further.
In addition, when observing from front, because cooler 11 is configured on the extended line of flow pass 20, so will cold air path 10 and flow pass 20 not bend in the lateral direction, just can cold air from cooler 11 pilot flow outlet 24.Therefore, the pressure loss of flow pass 20 can be reduced further.
