Describe below in conjunction with accompanying drawing, can more be expressly understood the present invention thus, more fully recognize various purpose of the present invention and advantage, wherein:
Fig. 1 is the side cross-sectional, view of conventional refrigerator;
Fig. 2 is the fragmentary, perspective view of refrigerator of the present invention;
Fig. 3 is the partial cross section view of refrigerator shown in Figure 2;
Fig. 4 is the circuit diagram of control refrigerator of the present invention.
Describe the present invention with reference to the accompanying drawings in detail.
Fig. 2 is the fragmentary, perspective view of refrigerator of the present invention; Fig. 3 is the partial cross section view of refrigerator shown in Figure 2.Refrigerating chamber 61 is formed at the top of refrigerator body 50, and refrigerating chamber 62 is formed at the lower part of refrigerator body 150.The condenser 69 that produces cold air is contained in the rear portion of refrigerator.
Refrigerating chamber 61 is connected with condenser 69 by refrigerating chamber conduit 71, and refrigerating chamber 62 is connected with condenser 69 by refrigerating chamber conduit 72.Pump orifice 71b, the 72b of refrigerating chamber conduit 71 and refrigerating chamber conduit 72 is opened on the zone near condenser 69, and the opening of outlet 71a, 72a is in refrigerating chamber 61 and refrigerating chamber 62.Fan 59 is configured between pump orifice 71b, the 72b and condenser 69 of conduit 71,72.Fan 59 blows the cold air of condenser 69 generations among conduit 71,72.
Pump orifice 71b, 72b are opened and closed by plate 75.Plate 75 is that the center is contained in rotationally near the zone of pump orifice 71b, 72b and according to its turned position opening/closing conduit 71,72 selectively with rotating shaft 76.When plate 75 was opened refrigerating chamber conduit 71 and closing cold room conduit 72, the cooling air of condenser 69 was input in the refrigerating chamber 61, and when plate 75 was opened refrigerating chamber conduit 72 and closed refrigerating chamber conduit 71, the cold air that condenser 69 produces was input in the refrigerating chamber 62.
The slewing area of plate 75 is determined by the support plate 81 that forms near refrigerating chamber conduit 71 pump orifice 71b with near the protuberance 85 that refrigerating chamber conduit 72 pump orifice 72b form.When plate 75 forwarded to support plate 81 state of contact, refrigerating chamber conduit 71 cut out, and when plate 75 forwards to when contacting with protuberance 85, refrigerating chamber conduit 72 cuts out.In this case, protuberance 85 is not formed in the position that the pump orifice 72b that makes refrigerating chamber 72 closes fully, is limited to a certain degree and be formed in the unlatching that makes pump orifice 72b, as shown in Figure 3.Therefore be fed to refrigerating chamber 62 in condenser 69 and 59 operating periods of fan more than the cold air of ormal weight, thus can correctly Keep cool the intensity of cooling of chamber, refrigerating chamber 62 requires more cooling down operation than refrigerating chamber 61.Protuberance 85 also can be formed on the position that refrigerating chamber conduit 72 cuts out fully.
Gear 91a, 91b and CD-ROM drive motor 90 be contained in plate 75 below.The power of CD-ROM drive motor 90 is transferred on the turning cylinder 76 of plate 75, and reduces rotating speed with gear 91a, 91b, thereby plate 75 is rotated.
CD-ROM drive motor 90 is by control circuit shown in Figure 4 100 controls.The control circuit 100 of CD-ROM drive motor 90 comprises: a pair of divider 101,102; A pair of temperature sensor; A pair of comparator 121,122; A NAND door 130; And switching transistor 140.
Voltage divider 101,102 comprises first divider 101 and second divider 102.First divider 101 is made up of two resistance R 1, R2.When the user set the intensity of cooling of refrigerating chamber 61, the ratio of resistance R, R2 changed, so 101 outputs of first divider are corresponding to the voltage of the setting intensity of cooling of refrigerating chamber 61.Second divider 102 comprises two resistance R 3, R4.When the user set the intensity of cooling of refrigerating chamber 62, the ratio of resistance R 3, R4 changed, so 102 outputs of second divider are corresponding to the voltage of the setting intensity of cooling of refrigerating chamber 62.
Temperature sensor 111,112 comprises first temperature sensor 111 that detects temperature in the refrigerating chamber 61 and second temperature sensor 112 that detects temperature in the refrigerating chamber 62.Temperature sensor 111,112 outputs correspond respectively to the voltage of the detected temperatures of refrigerating chamber 61 and refrigerating chamber 62.
The output voltage of the output voltage of first temperature sensor 111 and first divider 101 is passed to first comparator 121, and the output voltage of the output voltage of second temperature sensor 112 and second divider 102 is input to second comparator 122.In this state, 101,102 output voltage of divider is input to respectively on the end of oppisite phase of comparator 121,122, and the output voltage of temperature sensor 111,112 is input to respectively on the non-oppisite phase end of comparator 121,122.Therefore first comparator 121 is exported " height " logical signals when the output voltage of first temperature sensor 111 is higher than the output voltage of first divider 101, when the output voltage of second temperature sensor 112 is higher than the output voltage of second divider 102, second comparator, 122 output " height " logical signals.
The output of comparator 121,122 is input to NAND door 130.Only when the two the output of first and second comparators 121,122 all is " height ", NAND door 130 is just exported " low " logical signal, if at least one output is " low " in the output of first and second comparators 121,122, then export " height " logical signal.Therefore only when the temperature of refrigerating chamber 61 and refrigerating chamber 62 is higher than temperature corresponding to the setting intensity of cooling, the output of NAND door 130 is only " low " logical signal.
The output of NAND door 130 is passed to switching transistor 140.Switching transistor 140 only just switches to " connection " with relay 150 when it is input as " low ".When relay 150 was transformed into " connection " position, power supply just switched to CD-ROM drive motor 90 power supplies, thereby CD-ROM drive motor 90 rotates plate 75.When relay 150 was positioned at " pass " state, refrigerating chamber conduit 71 cut out by plate 75, and refrigerating chamber conduit 72 keeps opening state.Therefore, only when relay 150 forwards " connection " to, promptly only all be higher than when setting the temperature of intensity of cooling corresponding to it in the two temperature of refrigerating chamber 61 and refrigerating chamber 62, refrigerating chamber conduit 71 is just opened, thereby cold air enters refrigerating chamber 61.Because compare with refrigerating chamber 61, refrigerating chamber 62 uses more frequent, because the door of refrigerating chamber 62 is often opened/closed, so the loss of cold air is big, and the volumetric ratio refrigerating chamber 61 of refrigerating chamber 62 is big, so refrigerating chamber needs more cold air.According to the present invention, because refrigerating chamber conduit 72 is in the state of normally opening, so can prevent the reduction that the intensity of cooling of refrigerating chamber 62 causes because of frequent use.In addition, because refrigerating chamber conduit 72 is when being in closed condition, refrigerating chamber conduit 72 is still stayed open the state of some by protuberance 85, so there is slightly cold air send into refrigerating chamber 62 always.
As mentioned above, cold air can be assigned in refrigerating chamber 61 and the refrigerating chamber 62 effectively according to the present invention.
Though described with illustration the present invention in detail, very clear, this only is illustration and gives an example, and should not play the qualification effect, and the spirit and scope of the present invention are only determined by the clause of appended claims.
