The specific embodiment
Below, with reference to description of drawings the specific embodiment of the present invention.
Fig. 2 is an internal structure schematic diagram of seeing the refrigerator of an embodiment of the invention from the side.As shown in Figure 2, refrigerator of the present invention is three indirect cool refrigerators, comprises refrigerator main body, door of refrigerator, storeroom, refrigeration system, electronic baffle plate 4, door switch checkout gear 6 and control system.
Storeroom comprises refrigerating chamber (PC chamber) 7, temperature-changing chamber (SC chamber) 8 and refrigerating chamber (FC chamber) 9.Wherein PC chamber 7 is chamber between direct-cooled control, and SC chamber 8 and FC chamber 9 are chamber between air-cooled control, and the wind path of SC chamber 8 and FC chamber 9 communicates.
Door of refrigerator comprises refrigerating-chamber door (PC door) 1 corresponding to refrigerating chamber, corresponding to the temperature-changing chamber door (SC door) 2 of temperature-changing chamber and corresponding to the refrigerating chamber door (FC door) 3 of refrigerating chamber.
Fig. 3 sees the SC chamber of refrigerator of an embodiment of the invention and the internal structure enlarged diagram of the part between the FC chamber from the side.As shown in Figure 3, electronic baffle plate 4 is arranged between SC chamber 8 and the FC chamber 9.Electronic baffle plate 4 has temperature control model and door switch control model.
Under normal conditions, the open and-shut mode of electronic baffle plate 4 is according to the temperature of SC chamber 8 and controlled (temperature control model).Particularly, when the temperature of SC chamber 8 surpasses the temperature that sets, electronic baffle plate 4 be opened so that from the cold wind of air-cooled evaporimeter 5 by baffle plate air inlet 4-1, and then enter SC chamber 8 (shown in the direction of arrow among Fig. 3 and Fig. 5) by SC air inlet 8-1; When the temperature of SC chamber 8 was lower than the temperature that sets, electronic baffle plate 4 was closed.
And behind the signal of receiving from the positive closing of controlling substrate 10, electronic baffle plate 4 is forced closed, thereby intercepts the wind path (door switch control model) of FC chamber 9 and SC chamber 8.The concrete control flow of electronic baffle plate 4 as described later.
Fig. 4 is the schematic diagram of expression door switch checkout gear 6.As shown in Figure 3 and Figure 4, door switch checkout gear 6 is used to detect the on off state of SC door 2 and FC door 3, and detected information is delivered to control substrate 10.Door switch checkout gear 6 comprises SC door switch 6-1 and FC door switch 6-2 and the door switch testing circuit 6-3 that is separately positioned on SC door 2 and the FC door 3.
Fig. 5 is the schematic diagram of electronic baffle plate 4 and control system.As shown in Figure 5, control system comprises control substrate 10, lead and other electron component, it is used for detecting the various information of refrigerator, correspondingly sends various signals after handling by micro-control unit (MCU), thereby realizes the various devices in the refrigerator are controlled.
Fig. 6 is the control system pie graph of the refrigerator of present embodiment, and wherein the circuit that expression is used to detect the switch of FC/SC door and control electronic baffle plate 4 in the frame of broken lines constitutes.As shown in Figure 6, after control system detects the switching information of FC/SC door,, carry out signal and change afterwards and then import MCU and handle its input DC drive circuit, with the output signal input driving circuit, and then control the action of electronic baffle plate 4 according to the output signal of drive circuit.
Fig. 7 is the electric circuit inspection principle flow chart that expression is used to control the action of electronic baffle plate of the present invention, (a) expression basic procedure, (b) flow process of expression band defence program.The following control procedure that electronic baffle plate of the present invention is described with reference to Fig. 7.
The basic procedure in the key diagram 7 (a) at first.Electronic baffle plate 4 is in aforesaid temperature control model under normal conditions; And detect at least one chamber door (for example the FC door 3) when being opened, the access door mode switching control when door switch checkout gear 6.Particularly, door switch checkout gear 6 detects at least one chamber door (for example the FC door 3) when being opened, and by the relevant detection circuit relevant information is passed to control substrate 10; Send the signal of the electronic baffle plate 4 of positive closing from control substrate 10, and this signal is passed to electronic baffle plate 4, electronic baffle plate 4 is forced closed, thereby intercepts the wind path between SC chamber 8 and the FC chamber 9, and keeps the closed condition of electronic baffle plate 4 to be closed up to FC door 3; When door switch checkout gear 6 detects the above-mentioned compartment door of opening and is closed, relevant information is passed to control substrate 10 by the relevant detection circuit; Send the signal that electronic baffle plate is returned to the temperature control model from control substrate 10, and pass to electronic baffle plate 4, electronic baffle plate 4 is postponing to return back to the temperature control model behind the time t1 (for example 30 seconds～2 minutes) that sets.Under the door situation about being opened simultaneously of two Room, after the door that door switch checkout gear 6 detects two Room all is closed, send the signal that returns to the temperature control model to electronic baffle plate by control substrate 10 again.
Can be guaranteed by aforesaid control procedure: when SC door or FC door were opened, the wind path between FC chamber and the SC chamber was blocked, after SC door and FC door all are closed, and elapsed time t1, the wind path between two Room just may be opened.Thereby realize that wherein the switching of the door of a Room can not have influence on another chamber, can not cause the door of another chamber to eject because of the variation of air pressure.
In addition, after electronic baffle plate 4 is received the signal that returns to the temperature control model, can behind time delay t1, be opened to maximum rating earlier and be returned to the temperature control model again.Can avoid the temperature difference of electronic baffle plate 4 both sides to become big thus, thereby can prevent frosting on electronic baffle plate.
In actual use, the situation that the door of FC chamber or SC chamber is not closed after opening fully might occur,, the invention provides the electronic baffle controls flow process of the band defence program among Fig. 7 (b) at this situation.In the flow process of band defence program, after detecting the step of SC door 2 or FC door 3 for the state opened and the electronic baffle plate 4 of positive closing, the step whether shut-in time of detecting electronic baffle plate 4 has surpassed the time t2 (for example 30 seconds～2 minutes) that sets is set, if the shut-in time of electronic baffle plate 4 has surpassed the time t2 that sets, then make electronic baffle plate 4 be returned to the temperature control model; If the shut-in time surpasses the time t2 set, then continue with above-mentioned basic procedure in same step.Thus can holding circuit, prevent, SC room temperature excessive and can not obtain good problems such as control because of the electronic long electric current that causes of 4 shut-in times of baffle plate.
