Specific embodiment

Fig. 1 shows the lower part of refrigerating appliance according to the present invention with three-dimensional view.Storage inside the ontology 2 of utensil is empty Between 1 multiple lattice 4 for being stacked up and down are divided by panel 3 in mode common in the industry and can be by by the door 5 of lateral backstop Closure.Pull-out box 6 of the installation with the difference at least foreboard of local transparent in the lattice of bottom.

Multiple video cameras 7 are disposed on the inside of door.If may be mounted at attached door not shown in the figure on door 5 to put Frame, then video camera 7 is close in the lower section of the possible loading position of such door compartment respectively, to make the visual field of video camera 7 It is minimum by door compartment or the danger for being placed on chilled goods covering therein.

Not only in the case where door 5 is opened but also in the case where door closure, one in the lattice 4 is located at top Two video cameras 7 visual field in.The video camera 7 of lower section is arranged so that so that its in the case where door is closed respectively with pull The transparent region of one foreboard in case 6 is opposed and the content of the pull-out box be located at the lower section video camera view In.

Video camera 7 can also be mounted on one front on the side wall of ontology 2 or in panel 3 in door 5 by substitution Along upper, so as to from front, from chilled goods being loaded into parking space 1 before open utensil with station or will refrigeration The content of the similar angle monitor lattice 4 of the angle for the user that article takes out from parking space or pull-out box 5.

Fig. 2 shows the schematical sections of panel 3.Two plates 8,9 for being made of mineral glass and it is enclosed in two plates In tough and tensile plastic film 10 constitute safety glass composite construction.Upper plate 8 is simultaneously for vapor deposition or with other Substrate 11 that suitable mode deposits, the thin layer 12 made of indium tin oxide.12 shaping structures of thin layer are arranged at multiple Electrode 13 in the matrix of row and column.Electrode 13 can be connected on RC resonance circuit 14 by unshowned transistor switch, To be used as capacitor there, the capacitance of the capacitor is by the chilled goods that are placed in panel 3 above electrode 13 It influences, so as to be judged according to the resonance characteristics of resonance circuit 14.Therefore, each electrode 13 constitutes proximity sensor 15, root It may determine that according to the output signal of the proximity sensor, the panel 3 above relevant electrode 13 is occupied also by chilled goods It is empty.

The coil 16 of panel 3 and the coil 17 on the side of ontology 2 are close proximity arranged each other, to be used for resonance It is transmitted on coil 16 to the operation energy-sensitive of circuit 14.Herein, coil 16 and 17 in the side of panel 3 or ontology 2 On coding/decoding module 18 constitute passing interface 19,20 (see Fig. 3) together, by the passing interface by resonance circuit 14 Administrative unit 21 of the measurement result on the side of ontology 2 transmit.

The close inductively coupling of coil 16,17 can for example be accomplished in that coil 16 is arranged in panel 3 In fringe region, the fringe region is cooperated in the slot 22 in the internal container 23 of parking space 1, and the iron core of coil 17 24 surround slot 22 in foam side.

For the data transmitting from panel 3 to administrative unit, can be used arbitrary known format such as RFID or NFC, for the format, coding and decoding module 18 can obtain cheaply.

The bottom plate of pull-out box 6 can in a manner of identical with panel 3 equipped with proximity sensor rectangular component and For transmitting the interface of energy and data, to detect the distribution of the chilled goods in pull-out box 6 and to be passed to administrative unit 21 It send.

Fig. 3 shows the block diagram of refrigerating appliance.25 labels of the row and column component of the proximity sensor 15 of panel 3.If cold Hiding article part 26 is located in panel, then is therefore had by the proximity sensor 15 that chilled goods part 26 covers and connect with what is be not covered The different capacitance of nearly sensor 15.The signal for representing the capacitance is transmitted to administrative unit 21 by passing interface 19,20, and And administrative unit can be realized the map that panel 3 is made, and the area of panel being covered and be not covered is recorded in the map Domain.

The spacing for being preferably close to sensor 15 is less than 5mm, so as to the region of panel 3 covered by different chilled goods parts Proximity sensor 15 that is not being covered by a row respectively or being only partially covered separates, so that its measuring signal is bright It is different from the measuring signal for the sensor 15 being covered aobviously.But the spacing of proximity sensor 15 is smaller, then its measuring signal By the stronger of noise pollution, and in order to which the data volume that map is made and must transmit to administrative unit 21 is bigger.Therefore, The mutual spacing of sensor 15 is preferably greater than 0.5mm.

In addition, administrative unit 21 is connect with video camera 7, to receive from it image data.

According to as panel 3 and the when necessary sensor module 25 of pull-out box 6 and the data as provided by video camera, management is single Member 21 safeguards chilled goods inventory in memory 31, is such as explained in greater detail later in reference to Fig. 4.The inventory is for each refrigeration Article part 26 includes entry 32.Entry 32 is following data group, and the data group respectively includes chilled goods part extremely Title 34, set shelf-life 35 and the location parameter 36 of a few image 33 and/or relevant chilled goods part 26, it is described The title of relevant chilled goods part enables a user to again identify that out chilled goods part 26.Herein, location parameter 36 The close sensing of at least one covered by chilled goods part including parameter and sensor module 25 about sensor module 25 The coordinate of device 15, preferably all proximity sensors covered by chilled goods part, chilled goods part are located at the sensor module Detection zone in, this is identical as the parameter meaning of panel 3 or pull-out box 6 in current situations, and chilled goods are located at institute It states in panel or pull-out box.

It is also advantageous that administrative unit 21 and door turn on the switch 27 connections, because in the closure of door 5 and chilled goods exist The data of sensor module 25 do not occur in the time that distribution in parking space 1 can change not at all to administrative unit 21 Transmitting and its analysis and utilization, and the computing capability of administrative unit 21 can be used for other tasks.

The connection of administrative unit 21 to internet 28 or the private network of user, which can be set, to be used for, and on the one hand can The data for realizing remote access administrative unit 21, on the other hand provide following possibility to administrative unit 21: by comparing by taking the photograph Product image in image provided by camera and internet come identify the chilled goods part being loaded in parking space 1 and Therefore estimate that it stores validity period.

The display device 29 that connect with administrative unit 21 for example can integrate for exporting the screen of text and image and make In cooler tool, such as on the outside of door 5, but especially in the case where built-in refrigerating appliance, it is also possible to and utensil The separated component of shell, the component may be mounted on arbitrary suitable position, is for example mounted on and covers the utensil In furniture front.

The working method of administrative unit 21 is explained according to the flow chart of Fig. 4.It includes two process chains, described two processes Chain starts independently of each other.First pass chain is in step sl to detect that the opening of door 5 starts.Administrative unit 21 makes this Reaction, mode is all proximity sensors 15 for inquiring each sensor module 25 in step s 2, so as to according in this way The data of acquisition are formed in the map of the distribution of the chilled goods in each panel 3.

If determined in step s3, the map of panel 3 being achieved in that with obtained in the iteration before method Map without difference, then this method is back to step S2, so that new map is made.If map changes, the panel 3 Chilled goods centainly by movement, take out or put in.In order to distinguish between these three situations, administrative unit 21 will be covered The joint of sensor 15 firmly is group (S4), and described group is reciprocally separated by the sensor 15 not being covered respectively.These groups In each group correspond to a chilled goods part.Because user can only move chilled goods with two hands, can be moved simultaneously or The quantity for the chilled goods part that person puts again is small, thus by comparing two succeedingly made of map can easily and can By ground determine, chilled goods part whether moved and after movement its be located at where, so as in the chilled goods part (S5) location parameter 36 is updated in entry 32.

If the quantity of group reduces (S6) relative to map before, centainly there is chilled goods part to be lifted, so as to Perhaps it is put inside parking space 1 again or uses it in outside.Corresponding to the registration of such chilled goods part Item 32 is provided with note (S7), the note, if not being reloading with the chilled goods part in predetermined time interval, The entry 32 should be then deleted, and the process chain is back to step S2, to detect the further of chilled goods if necessary Operation.

If the quantity of group increases (S8) relative to map before, centainly there is group to be lifted and now before belonging to The chilled goods part that is laid down again belongs to newly added chilled goods part.In this case, administrative unit 21 is in step Manipulation is associated with the video camera 7 of relevant panel 3 in S9, and to obtain image, described image shows new chilled goods part.Cause Position for administrative unit 21 from chilled goods part new known to map in panel 3, in the picture can be easily by it It identifies.

In step slo, the segment for showing new chilled goods part of image may be displayed in display device 29, so as to User is promoted to specify chilled goods part preset maximum residence time in refrigerating appliance.Alternatively, in step slo, Administrative unit 21 can be in internet according to the picture search of new chilled goods part, to determine that it is according to the image What kind of product, how long is its storage validity period, and determines that the chilled goods part is being deposited according to these information independences The maximum residence time in 1 between emptying.

It in step s 11, is that new chilled goods part sets up entry 32 in the chilled goods inventory of administrative unit 21, The entry includes the image 33 of new chilled goods part 26 and/or when necessary includes chilled goods part 26 according to image 33 Determining title 34 and the shelf-life according to the preset maximum residence time calculating in parking space 1 of chilled goods part 26 35。

As long as door 5 is open, continuously repeatedly step S1-S11, continuously to detect user in panel 3 Chilled goods carry out all operations.

Independently with the position of door 5, it is repeated periodically second procedure chain.In step s 12, the second procedure chain is to select The entry in the chilled goods inventory of administrative unit 21 starts out.In step s 13, it checks whether to reach the chilled goods part The preset maximum residence time.If it is, the entry to be included in the list of entry to be shown in step S14 In；If it is not, then this method is directly to step S15, to examine, whether there are also entrys in chilled goods inventory It is untreated.If it is, this method is back to step S12, to handle next entry.If it is not, then to be shown The list of entry is completed.The list can be directly output in display device 29 to show immediately；But it can also be with Consider, it is only just that its is defeated when user is by correspondingly inputting on the User's Interface of utensil to require to output it Out, it or when user opens door 5, without requiring outputs it.Furthermore, it is possible to be arranged, when can be according in refrigeration object Entry in product inventory to user when showing the detail list of content of refrigerating appliance in display device 29, in the detail list The chilled goods part of middle prominent list, to suggest that user is finished as early as possible.

Certainly, the list of entry to be shown or with overdue chilled goods part can exsertile entry Complete chilled goods inventory can also be transmitted by internet 28 to long-range computer from user.

Method discussed above can also be by subtle adjustment for monitoring the content of pull-out box 6.Because working as pull When case 6 is drawn out, (when pull-out box 6 is pushed into ontology 2 between ontology 2 and two coils of the passing interface of pull-out box 6 When, described two coils are just mutually opposed), effective energy transmission and signal transmitting be it is impossible, herein according to Fig. 4 The first pass chain of method do not triggered by the opening of door 2, and trigger in the following way: door is closed or administrative unit 21 Can be identified again with the RFID reader communicative of pull-out box 6 according to after of short duration interruption, pull-out box 6 be drawn out and It is pushed into again.

In principle, the detection for the chilled goods being newly added in panel 3 can also just carry out after door re-closes.But It is that in contrast, discussed above in the case where door is opened, continuously detection has an advantage in that and can be easier Track the displacement of already existing chilled goods in ground.

In addition, in order to also can be realized the image for generating the chilled goods in parking space 1 in the case where door 5 is closed, Administrative unit can be connect with the lighting device 30 of parking space 1.
