In embodiments of the present invention, because the residing position of lamp assembly difference, promptly may be in the bottom of revolving door or drawer door, so the present invention can adopt two kinds of mounting means, below these two kinds of mounting means be introduced respectively.
Mounting means one, this kind mounting means are installed in the situation of revolving door bottom at the lamp assembly.Because the rotating shaft of revolving door can be made hollow, therefore can be so that the connecting line between switch module and the lamp assembly pass the hollow rotating shaft of revolving door, thus be the lamp assembly power supply.
Mounting means two, this kind mounting means are installed in the situation of drawer door bottom at the lamp assembly.But because drawer always needs to extract out back and forth, therefore the coupling assembling between switch module and the lamp assembly is required than higher, if adopt connecting line directly to link to each other, then pull out when the longest when drawer, lead is in the long status that is straightened, and when drawer is closed, distance between two end points of connecting line has been shortened again, because the gravity of connecting line self, and the gap between drawer and the casing is very little, therefore connecting line contacts with miscellaneous part possibly in the motion process of drawer, thereby twines with miscellaneous part, causes losing efficacy.
In order to address this problem, the present invention proposes the multiple preferred embodiment that is connected the coupling assembling between switch module and the lamp assembly, comprising:
Embodiment one,
In this embodiment, can adopt the mode of electromagnetic induction to address this problem.As shown in Figure 8, the structure chart for the last drawer of the embodiment of the invention one has electrical box 6 on the sidewall of drawer on this.As shown in Figures 9 and 10, in electrical box 6, be provided with second coil 8 and corresponding treatment circuit 9, on the refrigerator body madial wall, be provided with first coil 7, and second coil 8 be relative with the position of first coil 7.First coil 7 links to each other with switch module, and second coil 8 links to each other with lamp assembly 10 by corresponding treatment circuit 9.First coil, 7 emission electromagnetic energies, 9 processing offer lamp assembly 10 through treatment circuit after 8 inductions of second coil.Wherein, in one embodiment of the invention, treatment circuit 9 comprises full bridge rectifier, alternating current is converted to direct current offers lamp assembly 10.In this embodiment, do not have contact in kind between first coil 7 and second coil 8, each parts does not have movable part, so the reliability height.
In this embodiment, when last drawer is closed, first coil 7 and the 8 corresponding couplings of second coil, after the drawer of last drawer door bottom was drawn back, control signal second coil 8 that provides according to switch module provided electric energy to lamp assembly 10, and lamp assembly 10 begins illumination.If draw back drawer on this this moment, then Xia Fang drawer has been not suitable for picking and placeing food because should go up drawer stops, obviously do not need illumination this moment, therefore because last drawer is drawn back, first coil 7 and second coil 8 be mutual dislocation, not coupling, therefore lamp assembly 10 lighting-ofves this moment.
The advantage of this embodiment is not have movement parts, and reliable operation, shortcoming are that the electric energy of electromagnetic induction transmission is limited, high-power cost is higher, but consider that the LED lighting engineering is quite universal now, the big lumen of low-power is a mature technology, so this shortcoming can be ignored substantially.
In the present invention, Power Supply Assembly can be industrial-frequency alternating current, also can be the direct current of refrigerator master control borad output.
As shown in figure 11, coupling assembling circuit diagram for one embodiment of the invention, be input with the industrial-frequency alternating current among this embodiment, be transformed into direct current by first full bridge rectifier, inversion converts high-frequency ac current to and offers first coil 7 then, second coil 8 and 7 inductions of first coil and output high frequency electric are transformed to direct current through second full bridge rectifier again, thereby offer lamp assembly 10.
As shown in figure 12, be the coupling assembling circuit diagram of another embodiment of the present invention, therefore the direct current that this embodiment directly exports with the refrigerator master control borad need not first full bridge rectifier in the foregoing description as input.
Embodiment two,
Different with embodiment one is, this embodiment adopts connecting line directly to be connected with the lamp assembly with switch module, but in order to address the above problem, also needs to be provided with a spooler, and this spooler can be fixed on the casing or be fixed on the drawer.When last drawer was extracted out or closed, spooler applied default power with the tension connecting line to connecting line, prevents that this connecting line and miscellaneous part from twining.Present embodiment adopts the method for mechanical connection to realize, can make the freedom of motion transform length of conductor length according to drawer by spooler, so this embodiment can realize high-power connection, is not subjected to the influence of drawer status simultaneously, at any time power supply.
As shown in figure 13, be the spooler structure chart of the embodiment of the invention two.This spooler comprises the fixed part 14 that is fixed on casing or the last drawer, with the rotating part 12 that is socketed on the fixed part 14, rotating part 12 is free to rotate, and connecting line 20 is wrapped on the rotating part 12, one end of connecting line 20 links to each other with the lamp assembly, and the other end links to each other with switch module.This spooler also comprises wind spring 13, and an end of wind spring 13 links to each other with rotating part 12, and the other end links to each other with fixed part 14, and coil compression springs 13 when rotating part 12 rotates is so that wind spring 13 produces the driving force that drives rotating part 12.For example, after last drawer was drawn out, an end of connecting line 20 was along with last drawer door moves together, connecting line 20 driven rotary portions 12 rotate, rotating part 12 rotations are tightened up wind spring 13 compressions, and this moment is because the elasticity of wind spring 13 makes that the connecting line of going up between drawer door and the spooler is linearly.When last drawer door is closed, distance between drawer door and the spooler shortens, this moment, the elastic force owing to wind spring 13 made rotating part rotate, thereby unnecessary connecting line is wrapped on the rotating part, thereby also can keep the connecting line between drawer door and the spooler linearly.
Embodiment three,
In this embodiment, the mode that can adopt socket and plug to peg graft addresses this problem.As shown in figure 14, the structure chart for the last drawer of the embodiment of the invention three has plug 15 on the lateral wall of drawer on this.Shown in Figure 15 and 16, this coupling assembling comprises the socket 16 that is positioned on the refrigerator body madial wall, and socket 16 links to each other with switch module, and the plug 15 that is positioned at drawer side wall, plug 15 is relative with the position of socket 16, and plug 15 inserts socket 16 when last drawer is closed, and wherein, plug 15 links to each other with lamp assembly 17.
In this embodiment, socket 16 links to each other with switch module, if switch module comprises master control borad, then socket 16 links to each other with master control borad, has the direct current on the master control borad directly to be 17 power supplies of lamp assembly.
For present refrigerator, because that the guide rail of drawer is installed is very fine, so reliability high problem can not appear inserting etc., between plug 15 and the socket 16.
