The specific embodiment
Be described in further detail below in conjunction with the cold air supply device of the drawings and specific embodiments refrigerator of the present invention:
Shown in Fig. 3,4,5, the refrigerator of the cold air supply device of the present invention design comprise casing 1, with casing 1 form the refrigerating chamber 10 of the freezing preservation food that the dividing plate 16 of one divides and the refrigerating chamber 20 of stored refrigerated food, the refrigerating chamber door 11 that is arranged on casing 1 front switch refrigerating chamber 10 and switch refrigerating chamber 20 cold sotrage door 21, the refrigerating circulation system of the required cold air of cooling is provided for refrigerating chamber 10 and refrigerating chamber 20.
Refrigerating chamber 10 comprises the cooling chamber 2 of shield 14 (shroud) division that is arranged on refrigerating chamber door 11 rightabout rear sides; With cooling chamber 2 inner space width and thickness size accordingly, portion space and produce the evaporimeter 3 of the required cold air of refrigerator inside sets within it; Be arranged on the upside of evaporimeter 3, make the blowing fan 13 of the cold air forced flow of evaporimeter 3 generations; Be formed at the front of blowing fan 13, the flow of control cooler also has the grid that has delivery outlet 12a 12 that communicates with refrigerating chamber.
The cold air that dividing plate 16 inner formation are fed to refrigerating chamber 10 flow into the suction passage 16a of cooling chamber 2 once more.
Refrigerating chamber 20 is included as a plurality of shelves 22 of placing food and be arranged to sandwich construction in refrigerating chamber 20; Detect each regional temperature in the inside of refrigerating chamber 20, send a plurality of temperature sensors 24 of detection signal; Connect cooling chamber 2 and refrigerating chamber 20, the cold air in the refrigerating chamber 20 is fed to the cold air guiding channel of refrigerating chamber 20 inside.
Described cold air guiding channel comprises: pass to the central portion of dividing plate 16 from cooling chamber 2, the cold air that evaporimeter 3 is produced guides to the main feedline 23a of dividing plate 16 central parts; 23a communicates with main feedline, forms the cold air distributor chamber 23b of circular cross section in dividing plate 16 central authorities; Be arranged on the center of cold air distributor chamber 23b, start, distribute the air damper 25 of cold air according to the detection signal of temperature sensor 24; Form the divergent contour structure from cold air distributor chamber 23b, to the distribution carrier pipe of 20 4 angle supplies of refrigerating chamber cold air; Communicate with distributing carrier pipe, export the cold air delivery outlet 23c on the distribution carrier pipe that is assigned to refrigerating chamber 20.
Described air damper 25 comprises: the detection signal according to temperature sensor 24 produces motor rotating 25a; Combine the central shaft 25b that together rotates with motor 25a; Be installed on the central shaft 25b adjustable plate 25c of rotation and guiding cold air.
Described distribution carrier pipe comprises: the preceding right side of face of the guiding cold air that the front, left side of the guiding cold air that the right side, the back side of the guiding cold air that the left side, the back side of the guiding cold air that forms in the corner, left side at refrigerating chamber 20 back sides distributes carrier pipe 26a, form in corner, right side, refrigerating chamber 20 back side distributes carrier pipe 26b, form in the front, left side corner of refrigerating chamber 20 distributes carrier pipe 26c, form in the corner, right side, front of refrigerating chamber 20 distributes carrier pipe 26d.
As above after the refrigerator of the structure energising, compressor is compressed into the gas refrigerant of HTHP with the gas refrigerant of low-temp low-pressure, and the gas refrigerant of HTHP is condensed into the liquid refrigerant of HTHP during by condenser.The liquid refrigerant of HTHP is evaporated through becoming the gas refrigerant of low-temp low-pressure behind the evaporimeter 3, and carries out heat exchange by the evaporation and the ambient air of evaporimeter 3 through becoming the liquid refrigerant of low-temp low-pressure behind the expansion valve, produces cold air.
The rotation of the blowing fan 13 of aforesaid cold air by being arranged on casing 1 back side upside, forced air supply, 12a is fed to refrigerating chamber 10 by the refrigerating chamber delivery outlet, and the food that cooling is preserved is to uniform temperature; And remaining cold air is flowed downwards by shield 14 guiding, and the cold air guiding channel by refrigerating chamber 20 is fed to refrigerating chamber 20 inside.After the cold air that flows into was cooled to uniform temperature with the food in the refrigerating chamber, by refrigerating chamber 20 end faces, promptly the cold air suction passage 16b that forms on the dividing plate 16 flowed in the cooling chamber 2 once more, is cooled off by evaporimeter 3 again.
At this moment, be fed to the cold air of refrigerating chamber 20 from the cold air guiding channel, under the effect of the air damper 25 of the detection signal work by temperature sensor 24, centralizedly supply is to the position that temperature raises, so that promptly cool off.
As shown in Figure 6, when near the temperature refrigerating chamber 20 left surfaces rises, temperature sensor 24 detected temperatures of refrigerating chamber 20 left surfaces are set, and send detection signal.According to detection signal, motor 25a starts, drive central shaft 25b and adjustable plate 25c rotation, give left side, back side distribution carrier pipe 26a and front, left side distribution carrier pipe 26c supply cold air, do not flow into and do not have cold air among right side, back side distribution carrier pipe 26b and the preceding right side of face distribution carrier pipe 26d towards left surface formation.Concentrate output, left surface is promptly cooled off, thereby make refrigerating chamber 20 temperature inside even because cold air distributes carrier pipe 26a and front, left side distribution carrier pipe 26c to go up the delivery outlet 23c that forms by left side, the refrigerating chamber back side.
As shown in Figure 7, when near the temperature refrigerating chamber 20 right flanks rises, the temperature sensor detected temperatures of refrigerating chamber 20 right flanks is set, and sends detection signal.According to detection signal, motor 25a starts, drive central shaft 25b and adjustable plate 25c rotation, distribute carrier pipe 26b to reach preceding right side of face distribution carrier pipe 26d supply cold air to the right side, the back side that forms towards right flank, and do not have the cold air inflow among left side, back side distribution carrier pipe 26a and the front, left side distribution carrier pipe 26c.Because the delivery outlet 23c that cold air distributes carrier pipe 26d to go up formation by right side, refrigerating chamber back side distribution carrier pipe 26b and preceding right side of face concentrates and exports, and right flank is promptly cooled off, thereby make refrigerating chamber 20 temperature inside even.
The cold air supply device utilization of the refrigerator of the present invention's design is arranged on the air damper of the inner cold air distributor chamber that forms of dividing plate, gives high temperature position centralizedly supply cold air in the refrigerator, so that promptly it is cooled off.
