Description
Technical field
This utility model relates to refrigeration plant, particularly relates to the commercial cabinet of a kind of refrigeration.
Background technology
At present, refrigeration plant (refrigerator, refrigerator etc.) is widely used in people's daily life.Refrigeration plant is divided into domestic and commercialization according to use environment.Commercial refrigeration plant is commonly configured with transparent door body, in order to user observes the article deposited in casing and carries out purchase of taking away.And along with the development of RFID technique, in using RFID technique to carry out cabinet in commercial cabinet, checking of commodity is widely used, but, in actual use,, when detecting the commodity within cabinet, is easily there is detection mistake by the interference of external electromagnetic signal in the antenna of the RFID radio-frequency module within cabinet.How designing a kind of anti-tampering ability refrigeration plant by force with raising detection reliability is technical problem to be solved in the utility model.
Summary of the invention
This utility model provides the commercial cabinet of a kind of refrigeration, it is achieved improve the anti-tampering ability of the commercial cabinet of refrigeration to improve its detection reliability.
For reaching above-mentioned technical purpose, this utility model realizes by the following technical solutions:
The commercial cabinet of a kind of refrigeration, including cabinet, door body and RFID radio-frequency module, what described door body was switchable is arranged on described cabinet, described RFID radio-frequency module is arranged on described cabinet, the antenna of described RFID radio-frequency module forms electromagnetic field in described cabinet, described door body includes that doorframe and glass plate, described glass plate are arranged in described doorframe, and described glass plate is formed with electro-magnetic screen layer.
Further, described doorframe being additionally provided with electromagnetic shielding back-up ring, described electromagnetic shielding back-up ring is distributed around the inner ring of described doorframe, and described electromagnetic shielding back-up ring is formed with the bulge-structure protruding from described doorframe inner surface.
Further, the inner ring edge of described electromagnetic shielding gear extends at described glass plate, forms electromagnetic shielding overlapping region between described electromagnetic shielding gear and described electro-magnetic screen layer.
Further, under described door body is closed, described bulge-structure is 1.5mm-4.5mm with the distance of described cabinet.
Further, described glass plate includes outer glass plate and interior glass plate, and described outer glass plate is positioned at the outside of described glass plate, and described electro-magnetic screen layer is formed on described outer glass.
Further, described antenna is arranged on the sidewall of described cabinet, top and/or bottom.
Compared with prior art, advantage of the present utility model and good effect be: by forming electro-magnetic screen layer on a glass, electro-magnetic screen layer can effectively stop that the electromagnetic signal in the external world enters in cabinet, so that it is guaranteed that RFID radio-frequency module by antenna can commodity in detecting box body accurately, improve the anti-tampering ability of the commercial cabinet of refrigeration to improve its detection reliability.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of the commercial cabinet embodiment of this utility model refrigeration;
Fig. 2 is the explosive view of door body in the commercial cabinet embodiment of this utility model refrigeration；
Fig. 3 is door body and the local assembling view of cabinet in the commercial cabinet embodiment of this utility model refrigeration.
Detailed description of the invention
For making the purpose of this utility model embodiment, technical scheme and advantage clearer, below in conjunction with the accompanying drawing in this utility model embodiment, technical scheme in this utility model embodiment is clearly and completely described, obviously, described embodiment is a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
As shown in Figure 1-Figure 3, the commercial cabinet of the present embodiment refrigeration, including cabinet 1, door body 2 and RFID radio-frequency module, what described door body 2 was switchable is arranged on described cabinet 1, the antenna of RFID radio-frequency module forms electromagnetic field in described cabinet 1, described door body 2 includes that doorframe 21 and glass plate 22, described glass plate 22 are arranged in described doorframe 21, and described glass plate 22 is formed with electro-magnetic screen layer 23.
Specifically, the commercial cabinet of the present embodiment refrigeration carries out management and control by RFID radio-frequency module to the commodity posting electronic tag in cabinet, can the most quickly judge kind and the quantity of commodity.The commodity in cabinet 1 are chosen for the ease of user, door body 2 uses glass plate 22 to form transparent door body, oneself required commodity whether is had in allowing users to observe cabinet 1 through glass plate 22, and simultaneously, in order to avoid external electromagnetic field interferes impact to the electromagnetic field in cabinet 1, it is provided with electro-magnetic screen layer 23 on glass plate 22, to realize the electromagnetic signal interference cutting off between cabinet 1 inside and outside, improves the accuracy of detection of RFID radio-frequency module.
Further, doorframe 21 being additionally provided with electromagnetic shielding back-up ring 24, described electromagnetic shielding gear 24 circle is distributed around the inner ring of described doorframe 21, and described electromagnetic shielding back-up ring 24 is formed with the bulge-structure 241 protruding from described doorframe 21 inner surface.Concrete, after door body 2 is closed, it is formed with interval between door body 2 and cabinet 1, the bulge-structure 241 of electromagnetic shielding gear 24 formation stretches towards cabinet 1 direction, enter in cabinet 1 from the interval between door body 2 and cabinet 1 such that it is able to shield external electromagnetic signal by bulge-structure 241, thus more effectively improve the accuracy of detection of RFID radio-frequency module.Wherein, described bulge-structure 241 is 1.5mm-4.5mm with the distance of cabinet 1.Further, electromagnetic shielding keeps off 24 inner ring edges and extends to form electromagnetic shielding overlapping region at glass plate 22 and with electro-magnetic screen layer 23.It addition, glass plate 22 includes outer glass plate 221 and interior glass plate 222, and electro-magnetic screen layer 23 is formed on outer glass plate 221.
