The present invention proposes a kind of refrigerator.
Referring to Fig.1 and 2, in an embodiment of the present invention, the refrigerator 100 includes the casing 10 with opening, is used forThe door body 20 that is open described in folding, the display control board (not shown) being arranged in the door body 20 and the master for being arranged at casing 10Box and RFID component are controlled, primary control box is used for the operation power that refrigerator is powered and controlled for the display control board, the RFID groupsPart includes being used to obtain the RFID signal acquisition module (not shown) of RFID label tag signal in the casing 10 and for identifyingThe RFID signal read module 31 of RFID label tag signal, the RFID signal acquisition module and the RFID signal read module 31Connected by the first signal wire 40, the RFID signal read module 31 is connected with the display control board by secondary signal line 50Connect, the RFID signal read module and the primary control box are separately positioned.In the present embodiment, secondary signal line 50 communicates for RFIDLine.
RFID signal read module 31 has been arranged in refrigerator primary control box by prior art in order to easy for installation, but master controlInclude the device that power module, frequency converter etc. make a noise in box, because not having barrier between RFID signal read module 31And directly affect identification of the RFID signal read module 31 to RFID label tag signal.The present embodiment is by RFID signal read module 31Separate and set with refrigerator primary control box, so as to eliminate the interference that each device makes a noise to RFID signal read module 31 in primary control box.
RFID identification principle is as follows in refrigerator：The RFID label tag of food in casing is got by RFID signal acquisition moduleSignal, then RFID signal read module 31 is transferred to by the first signal wire 40.RFID signal read module 31 reads RFID marksThe food type of RFID label tag signal is identified after label signal and determines the position of the RFID label tag signal, then passes through the second letterNumber line 50 is transferred to display control board, is exported food type and position to user by display control board.
Further, RFID signal read module 31 is arranged at the top of casing 10.Refrigerator necessity is provided with casing 10Blower fan and compressor, blower fan and compressor can also produce noise to influence RFID signal read module 31 in the course of the workIdentification.The present embodiment is by the way that RFID read modules 31 to be arranged to the top of casing 10, when door body 20 closes, blower fan andThe noise that compressor is sent is stopped by the metal shell of casing 10, makes RFID read modules 31 from blower fan and compressor instituteThe interference of the noise sent, so as to improve the identification accuracy of RFID read modules 31.Specifically, the material of casing 10 is steelMaterial.
Preferably, the inside of door body 20 includes spool, and it is neighbouring that the first end 21 of spool is opened in the top surface of door body 20, the second endDisplay control board, secondary signal line 50 pass through spool from first end 21, and are stretched out from the second end and read mould to connect RFID signalBlock 31 and display control board.
Display control board is arranged at side of the door body 20 towards user, and the RFID on display control board Yu the top of casing 10 believesOn the premise of number read module 31 is connected by secondary signal line 50, pass through to set in door body 20 and house secondary signal line 50Spool, avoid secondary signal line 50 exposed to strengthen aesthetic property, while also avoid secondary signal line 50 from extending around door body 20The length of secondary signal line 50, reduces the noise jamming that secondary signal line 50 is subject to, and further enhances RFID signal readingThe identification accuracy of module 31.
Further, door body 20 and casing 10 are be hinged, and the first end 21 of spool is opened in the top surface of door body 20 close to be hingedThe one end at place.Because hinged place is in 20 folding of door body, the change in location minimum of side is hinged, by first end 21 located at door body 20Top surface can avoid user from pullling secondary signal line 50 when opening door body 20 close to one end of hinged place, ensure that user justOften use.
In a possible embodiment of the invention, display control board is set close to the first end 21 of spool, and RFID signal is readModulus block 31 is set close to the first end 21 of spool.So as to shorten RFID signal read module 31 and display control board away fromFrom, and then the distance of secondary signal line 50 is shortened, reduce the noise jamming that secondary signal line 50 is subject to, further enhanceThe identification accuracy of RFID signal read module 31.
Further, refrigerator 100 also includes the knuckle guard 60 for being arranged at the top surface of casing 10, for covering the He of first end 21The secondary signal line 50 exposed between RFID signal read module 31.Knuckle guard 60 is towards the top surface of casing 10 and the top of door body 20Face forms an inner chamber, and the one end of knuckle guard 60 is connected with casing 10, and the other end extends to the top surface of door body 20 and covers spoolFirst end 21, so as to which the secondary signal line 50 exposed between first end 21 and RFID signal read module 31 is housed in into inner chamberIt is interior, play a part of covering the secondary signal line 50 exposed between first end 21 and RFID signal read module 31, ensure refrigerator100 overall aesthetic degree.In the present embodiment, RFID signal read module 31 is arranged in the host cavity of knuckle guard 60, is also functioned toThe effect of RFID signal read module 31 is covered, further improves the overall aesthetic degree of refrigerator 100.
Fig. 3 and Fig. 4 are please referred to, refrigerator 100 also includes being arranged at the inside of casing 10 and with casing 10 with side openingCase courage, the top of casing 10 offer through hole (not shown), and RFID signal acquisition module includes the day for being arranged at case courage outer surfaceLine, the first signal wire 40 pass through through hole to connect antenna and RFID signal read module 31.Case courage is used in the memory storage of casing 10Food, user's opening door body 20 can be taken out of case courage or accommodating food.Antenna, which is arranged on the outer surface of case courage, is used for spokeThe inner space of case courage is penetrated, to obtain the FRID label information of food in case courage.In the present embodiment, through hole is opened in casing 10 and pushed upThe region that face is covered by knuckle guard 60, therefore when the first signal wire 40 is through through hole connection RFID signal read module 31 and antennaIt can be covered by knuckle guard 60, improve the overall aesthetic degree of refrigerator 100.Specifically, the first signal wire 40 is feeder line.
Further, case courage includes stacking the first case courage 71 and the second case courage 72 set, and antenna includes first antenna 321With the second antenna 322, wherein first antenna 321 is arranged at the first face of the first case courage 71, and the second antenna 322 is arranged at the second caseSecond face of courage 72, so as to form the potential difference of two antennas, and the plane where the first face is relative with the plane where the second faceSet, i.e. case courage enables the antenna 322 of first antenna 321 and second to improve the first packing list 71 and the between two antennasThe radiance of two case courages 72, improve acquisition accuracy of the antenna to RFID label tag signal in case courage.In the present embodiment, case courageThe buckle for fixed antenna is additionally provided with the axis of the outer surface of opposite sides, is enabled the antenna in homogeneous radiation case courageSpace.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the scope of the invention, it is every at thisUnder the design of invention, the equivalent structure transformation made using description of the invention and accompanying drawing content, or directly/it is used in indirectlyHe is included in the scope of patent protection of the present invention related technical field.
