Embodiment
Describe embodiments of the invention below in detail, the example of described embodiment is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Below by the embodiment that is described with reference to the drawings is exemplary, only is used to explain the present invention, and can not be interpreted as limitation of the present invention.
The present invention is electric component power supply on the drawer door body by non-contacting mode, owing to connect by induction between first coil and second coil, does not therefore have movement parts, connection reliability height.
As shown in Figure 1, the structure chart for the last drawer of the drawer-type refrigerator of the embodiment of the invention has electrical box 6 on the sidewall of drawer on this.Shown in Fig. 2 and 3, on the refrigerator body madial wall, be provided with first coil, 7, the first coils 7 and link to each other with the first treatment circuit (not shown), first treatment circuit further links to each other with Power Supply Assembly.In electrical box 6, be provided with second coil 8 and corresponding second treatment circuit 9, and second coil 8 is relative with the position of first coil 7.Wherein, second treatment circuit 9 comprises second full bridge rectifier.In an embodiment of the present invention, second treatment circuit 9 alternating current that the induction of second coil 8 is generated is converted to direct current and offers at least one electric component 10 on the door body that is positioned at drawer.First coil 7 emission electromagnetic energies are handled to offer through second treatment circuit 9 after 8 inductions of second coil and are positioned at electric component 10.
Wherein, in one embodiment of the invention, as shown in Figure 4, be the connecting circuit schematic diagram of one embodiment of the invention, be input with the industrial-frequency alternating current among this embodiment, first treatment circuit comprises first full bridge rectifier and the inverter circuit that links to each other with first full bridge rectifier.By first full bridge rectifier industrial-frequency alternating current is transformed into direct current, 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 current, be transformed to direct current through second treatment circuit 9 again, thereby offer electric component 10.
Wherein, in another embodiment of the present invention, as shown in Figure 5, be the connecting circuit schematic diagram of one embodiment of the 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.
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 a preferred embodiment of the invention, electric component 10 may be embodied as the lamp assembly.The lamp assembly is positioned at the bottom of drawer door body and thinks that the drawer under the drawer provides illumination.
Be that example is introduced with refrigerator shown in Figure 6 below, but need to prove that refrigerator shown in Figure 6 only is for purpose clearly, comprise two drawer doors in the refrigerator in the figure, but be not that the present invention is only applicable to refrigerator shown in Figure 6, the refrigerator of other types also can be applied among the present invention.
As shown in Figure 6, refrigerator comprises revolving door 1, is positioned at first drawer door 2 and second drawer door 3 under the revolving door 1, so revolving door 1 is revolving door with respect to first drawer door 2, and first drawer door 2 is drawer door with respect to second drawer door 3.Be provided with the lamp assembly 10 that is used to the illumination of first drawer in the bottom of revolving door 1, be provided with the lamp assembly 11 that is used to 3 illuminations of second drawer door in first drawer door, 2 bottoms.
Specifically, in this embodiment, when first drawer door 2 is closed, first coil 7 and the 8 corresponding couplings of second coil, after the drawer of first drawer door, 2 bottoms was drawn back, control signal second coil 8 that provides according to switch module provided electric energy to lamp assembly 11, and lamp assembly 11 begins illumination.If draw back this first drawer door 2 this moment, then second drawer door 3 stops because of first drawer door 2, be not suitable for picking and placeing food, obviously do not need illumination this moment, therefore drawn back owing to first drawer door 2, first coil 7 and second coil 8 be mutual dislocation, not coupling, therefore lamp assembly 11 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 technology is quite universal now, the big lumen of low-power is a mature technology, so this shortcoming can be ignored substantially.
In another embodiment of the present invention, the contactless power supply device of drawer-type refrigerator of the present invention also comprises the switch module that control lamp assembly 11 is opened or closed.Wherein, lamp assembly 11 is arranged in the groove of first drawer door, 2 bottoms, and lamp assembly 11 comprises lighting lamp group and the lampshade that is made of light-transmitting materials.Whether switch module is drawn back according to following drawer door, controls lamp assembly 11.Switch module is to be installed in the switch on the wallboards of box body after the drawer, contacts with switch after drawer pushes refrigerator fully, when drawer contacts with switch, closes lamp assembly 11.Particularly, this switch module comprises the switch that is installed on the box inside wall and is positioned at the switch block of drawer outside wall, the switch block is touched this switch after drawer pushes refrigerator fully, switch cuts out lamp assembly 11, after drawer is extracted out, the switch block does not contact with switch, and then the switch bounce-back is returned to initial condition, thereby control lamp assembly 11 is opened.
The present invention is electric component power supply on the drawer door body by non-contacting mode, owing to connect by induction between first coil and second coil, does not therefore have movement parts, connection reliability height.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification that scope of the present invention is by claims and be equal to and limit to these embodiment.
