Description

  The present invention relates to a refrigerator equipped with an RFID tag suitable for a service system using a communication network such as the Internet.

  In general, there is a system that improves the convenience of home appliances by exchanging information with home appliances via a communication network such as the Internet. For example, it is possible to connect a refrigerator to the Internet and transmit the details of the failure to a service provider so that accurate failure repair is possible (see, for example, Patent Document 1).

  The devices used in such a system are not limited to refrigerators, and other home appliances are often similar. And such devices are called so-called Internet home appliances. In recent years, with the development of communication infrastructure, it has become more and more widespread, and multiple home appliances in the home will be equipped with such communication functions. Is predicted.

JP 2002-295939 A

  As home appliances are being computerized as described above, devices called white goods are used in daily life regardless of age or gender. The That is, as long as a single refrigerator is only connected to the Internet, there is no problem in usability and the service can be fully enjoyed. However, when the computerization of home appliances spreads and multiple home appliances are connected to the Internet and become a service target, what kind of solid the target device shows in the bidirectional exchange of device information, such as children and the elderly Is difficult to understand and difficult to use. In addition, for example, when two refrigerators are held in the home, a problem that the temperature inside the refrigerator is set incorrectly can be predicted.

  Therefore, the present inventors have provided an RFID (Radio Frequency IDentification) tag for performing short-range communication with a device, and exchanges information directly by bringing a portable terminal such as a mobile phone having a short-range communication function close to the device. We have considered and demonstrated a system that provides various services by connecting information from a mobile terminal to a host computer via an Internet line.

  According to this system, even when there is a selection of multiple home appliances, it always reads the device information by touching the mobile device to the target home appliance body during communication, so children and the elderly Can be understood intuitively without misunderstanding the object, can be used with confidence without being lost in operation, and is easy to use.

  As information processing of such white goods is progressing, it is necessary to identify the refrigerator in order to provide services. That is, an identification symbol associated with the product name, product color, product specification, production number, production location, etc. of the refrigerator is given to the product, which is extracted and identified by the communication function.

  On the other hand, in the refrigerator, information such as the product name is similarly pasted on the product label. Therefore, it is necessary to assemble two parts with similar information to the refrigerator. The two parts are, for example, an RFID tag with a product label and an identification symbol, and the product label can be visually confirmed, but the RFID tag includes electronic information but cannot visually confirm the information content. .

  When an RFID tag that identifies such a refrigerator is incorrectly attached, when the refrigerator information is displayed on an information-communication terminal or the like, different types of refrigerator information are displayed, or the wrong refrigerator information is provided via the Internet. This is an important management item that should not be mistaken in the event of problems such as providing incorrect information to service personnel during service repairs.

  In addition, the visually recognizable product label can be confirmed by anyone and is relatively easy to manage, but RFID tags that are not visually changed are parts that are very difficult to manage. In addition, the refrigerator is configured to be assembled after a number of parts are sub-assembled, and these parts are exchanged when there is a part failure during production, distribution, or customer. In particular, the refrigerator door, which is a candidate location for installing the RFID tag, can be easily removed, is frequently replaced due to scratches on the appearance, etc., and may be removed when passing through a narrow passage during product transportation. is there.

  The present invention has been made in view of these points, and can manage product labels and RFID tags in a unified manner, prevent confusion due to device information mismatch, and facilitate services such as component management and component replacement. The object is to provide a refrigerator with an RFID tag that can be used.

  In order to solve the above problems, the refrigerator of the present invention includes an RFID tag storing device information, and has a configuration in which a product label indicating an individual refrigerator and the RFID tag are arranged in the refrigerator component as the same assembly component. .

  For example, a refrigerator door part provided with a product label and an RFID tag.

  Thereby, since the plurality of pieces of product information of the refrigerator are configured as one component group (components in which the product label and the RFID tag are set), the chance of giving different information can be greatly reduced. For example, if a product label and an RFID tag are attached to separate refrigerator components, these refrigerator components are assembled in separate refrigerators. In other words, the product label and RFID tag that are assembled in one refrigerator. When product information is different, the product label and the RFID tag are likely to be generated, but the product label and the RFID tag are configured as one component group (a component in which the product label and the RFID tag are a set), and the refrigerator assembly component, for example, the refrigerator Therefore, the above-described problem can be reliably prevented. In addition, it is easy to confirm the content of product information to be given to the RFID tag by the product label notation. Furthermore, the problem that the attached information cannot be visually confirmed with the RFID tag can be solved by confirming the product label, and it can be visually discriminated by the product label without reading the information of the RFID tag by a dedicated device. Become.

  The present invention manages a plurality of parts given product individual information as one sub-assembly part, so that product labels and RFID tags can be managed centrally, and management of RFID tags that cannot be visually distinguished can be easily performed. Providing a highly reliable refrigerator with an RFID tag that can prevent mistakes in attaching parts or replacing parts because the individual information given to the product label and the RFID tag is not different. Is possible.

  1st invention is equipped with the RFID tag which memorize | stored apparatus information, and is set as the structure which has distribute | arranged the product label which shows the individual | solid of the refrigerator, and the said RFID tag to the refrigerator component as the same assembly component. Thereby, since the plurality of pieces of product information of the refrigerator are configured as one component group (components in which the product label and the RFID tag are set), the chance of giving different information can be greatly reduced. For example, if a product label and an RFID tag are attached to separate refrigerator components, these refrigerator components are assembled in separate refrigerators, in other words, product information of product labels and RFID tags assembled in one refrigerator. However, the product label and the RFID tag are configured as a group of parts (parts in which the product label and the RFID tag are a set) to form the same assembly part. Since the door part is provided, the above-described problem can be reliably prevented. Therefore, the device information indicated by the product label affixed to the refrigerator component and the device information indicated by the RFID tag do not become inconsistent, and the component information can be easily managed using the device information of the RFID tag. Product label and RFID tag can be managed centrally, and the refrigerator components assembled by looking at the contents of the product label at the time of production are different from the device information described in the RFID tag, and the user approaches the mobile terminal The device information transmitted in this way does not cause erroneous replacement of parts unlike the genuine product.

  In addition, it is easy to confirm the content of product information to be given to the RFID tag by the product label notation. Furthermore, the problem that the attached information cannot be visually confirmed with the RFID tag can be solved by confirming the product label, and it can be visually discriminated by the product label without reading the information of the RFID tag by a dedicated device. Become.

  In the second aspect of the invention, the refrigerator component is a door, and the problem that occurs due to replacement or incorrect assembly of a door that is frequently exchanged or detached and is relatively easy to assemble to the refrigerator main body. The reliability of parts replacement services and the like can be improved.

  According to a third aspect of the present invention, a refrigerator control unit of a refrigerator to which a door is attached includes a device information storage unit that stores device information similar to an RFID tag provided in a refrigerator component, and the device information of the RFID tag and the refrigerator control unit If the device information does not match, a warning is issued.If the doors to be replaced are different, a warning is issued, so there is no mistake in replacement and the reliability of the parts replacement service is extremely high. can do.

  In the fourth invention, the second or third RFID tag is provided on the outer surface of the door and the product label is attached to the inner surface of the door, and the RFID tag is provided on the outer surface of the door. There is no need to open the door when the terminal is approached, improving usability.

  In a fifth aspect of the invention, the RFID tag of the second to fourth aspects of the present invention is configured to be provided on the uppermost door among a plurality of doors.

  Accordingly, it is possible to provide a highly reliable refrigerator by preventing a communication failure peculiar to the refrigerator or contamination of the mobile terminal, which is likely to occur due to spillage of moisture and dirt of the food at the time of taking in and out the food. That is, the problem of the refrigerator in the case where communication is performed by touching the mobile terminal is in the place where the RFID tag is provided. With conventional wireless devices, there was no problem even if it was out of reach or invisible, such as the back or top of the refrigerator, but it was intuitive at close distances to prevent mistakes with other home appliances In order to realize communication by a touching operation, it is essential to arrange an RFID tag in a reachable range from the viewpoint of ease of use, that is, in the front part of the refrigerator.

  However, when the RFID tag is disposed on the front surface of the refrigerator, water and dirt adhering to the hand are held on the surface of the RFID tag antenna arrangement portion of the refrigerator body in order to bring the hand holding the portable terminal close to the refrigerator body. In some cases, when the food is attached or removed, moisture or dirt of the food spills out and adheres to the surface of the RFID tag antenna mounting portion, and the communication state may deteriorate.

  Also, even if the hand is not soiled, when the mobile terminal itself, which is a precision device, or the hand holding the mobile terminal is placed close to the refrigerator body for communication, dirt and water on the refrigerator body will adhere to the hand. As a result, problems such as hindering the operation of the touch panel of the mobile terminal and making the screen difficult to see occur.

  However, in the refrigerator of the present invention, since the food part cannot be taken out from the storage room above the communication part by providing the communication part on the uppermost door, moisture or dirt drops and adheres at the time of taking out. There is nothing.

  In addition, when the refrigerator is opened and closed, the cool air in the refrigerator flows out to the outside, and the cool air spills onto the door at the bottom of the opened door, and the temperature is lowered. If the temperature of the surface of the RFID tag provided on the door falls below the dew point due to cold air leakage, condensation may occur and radio waves may be hindered by moisture, which may cause problems. Therefore, the door of the storage chamber above the RFID tag cannot be opened and closed, the temperature of the RFID tag does not decrease, and there is no fear of communication failure due to condensation.

  This is particularly effective in a layout in which a freezer compartment having a low internal temperature is arranged at the top, since the temperature of the leaked cold air is low and the door temperature at the bottom tends to decrease.

  In addition, the communication operation of the terminal for short-range communication needs to be close to the home appliance, but the terminal itself or the hand held may get dirt or moisture from the refrigerator, causing malfunction of the touch panel of the mobile terminal. However, it is possible to prevent the problem that the screen is difficult to see and the quality of the terminal from being adversely affected by suppressing the dirt and moisture from adhering to the communication unit.

  Furthermore, information on the refrigerator side, for example, the number of times of opening and closing the door can be obtained by displaying the information on the display unit of the portable terminal, and the use of display power as in the case where the display unit is provided on the refrigerator main body side can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

  In the figure, reference numeral 1 denotes a refrigerator body, which is provided with a plurality of storage chambers 2, 3, 4, 5, 6 as shown in FIG. These storage rooms are a refrigerator room 2, an ice making room 3, and a switching room 4 located on the side of the ice making room 3 from above (switchable from a freezing room temperature of about -18 ° C to a vegetable room temperature of about 6 ° C), a freezing room 5 、 Vegetable room 6 The layout is appropriately set as necessary.

  The refrigerator main body 1 is composed of an outer box 1a mainly using a steel plate, an inner box 1b formed of a resin such as ABS, and a hard foam filled and foamed in a space between the outer box 1a and the inner box 1b. It is comprised with the urethane foam 1c. Furthermore, the vacuum heat insulating material 1d is embedded in the hard urethane foam in order to partially enhance the heat insulating performance as necessary. For example, as shown in FIG. 2, a vacuum heat insulating material 1d is attached in the space of the back surface corresponding to the ice making chamber 3, the switching chamber 4, and the freezing chamber 5 to form a composite with the hard urethane foam 1c.

  Further, the top surface portion of the refrigerator body 1 has a stepped recess shape toward the back side of the refrigerator, and a machine room 7 is formed in the step-like recess, and the compressor room 8, moisture is formed in the machine room 7. A high-pressure side component of the refrigeration cycle such as a dryer (not shown) for removal and a refrigerator control unit (not shown) are accommodated to increase the storage capacity of the lowermost vegetable compartment.

  The cooler 9 constituting the low-pressure side of the refrigeration cycle is disposed behind the freezer compartment 5 so as to cool the storage chambers 2 to 6 by forcibly blowing the cool air generated by the cooler 9 by the cooling fan 10. It has become.

  Each of the storage chambers 2 to 6 is configured to be opened and closed by doors 11, 12, 13, 14, and 15 provided corresponding to the storage chambers 2 to 6, respectively. Each of the doors 11 to 15 has a handle portion 16, Similar to the refrigerator body 1, a hard urethane foam 1c is filled and foamed in a sealed interior with a metal surface plate and an inner box plate made of ABS resin or the like.

  In the refrigerator of this embodiment, the door of the refrigerator compartment 2 located at the uppermost part is a double door, and is composed of two doors 11a and 11b having different left and right areas. The right door 11b having a large area is configured to be opened simply by lightly pushing the door surface by the automatic door opening / closing mechanism 17, and the opening / closing is detected by a door opening / closing detection unit (not shown). Further, an operation unit 18 is provided at the end of the right door 11b in the vertical direction, and direct current wiring for supplying power and transmitting control signals to the operation unit 18 is provided, and the alternating current wiring is connected to the right door. It is given to left door 11a, without arranging 11b.

  Here, as shown in FIG. 4, the operation unit 18 includes a resin operation name plate 18a provided in the vertical direction of the outer surface of the end of the door 11b, and a resin substrate housing located inside the operation name plate 18a. Section 18b, a first board 18c that is positioned further inside the board storage section 18b and that faces a display section and switches described later on the inner surface of the operation nameplate 18a, and an RFID tag 21 that is the subject of the present invention. The RFID tag 21 includes a second substrate 18d facing the inner surface portion of the operation nameplate 18a. Since the RFID tag 21 is covered with a resin material, it is possible to prevent the influence of power transmission due to metal. In addition, even if the door is made of a glass material instead of a metal and the operation unit is closely arranged inside the glass, the influence of the radio wave due to the metal material can be prevented.

The RFID tag 21 is registered with device information including an ID number that enables the product to be identified, and the individual product can be identified by transmitting and receiving the ID number. Of course, the RFID tag 21 obtains information such as the cooling set temperature, the number of times of opening / closing the door, or the total opening time of the door as information during the operation of the refrigerator from the refrigerator control unit. To send and receive externally.

  As shown in FIG. 5, the RFID tag 21 includes a temperature setting electrostatic touch setting switch 19 provided in the operation unit 18 and a setting state display unit 20 disposed above the setting switch 19. It is arranged below. That is, the RFID tag 21 is provided on the outer surface of the door 11b, and when the user brings the portable terminal 22 such as a mobile phone, a smartphone, or a PDA close without opening the door as shown in FIG. A home appliance service system that exchanges information with the terminal 22 and displays the information on a display unit (not shown in FIG. 1) of the portable terminal 22 or transmits / receives to / from a host computer of a service provider via the Internet line To do. In this embodiment, the RFID tag 21 is of a passive tag type and a proximity type with a communication distance of 100 mm or less.

  Further, as shown in FIG. 6, a product label 23 on which device information such as a product number, a refrigerant name, and a refrigerant amount is written is attached to the inner surface of the door 11b provided with the RFID tag 21. That is, the product label 23 and the RFID tag 21 are attached to one door 11b which is a refrigerator component as the same assembly part.

  Hereinafter, one method for mounting the product label 23 and the RFID tag 21 as the same assembly component will be described with reference to FIG.

  First, in step 11, the parts are assembled as in the conventional case, and the refrigerator is assembled. At the time of assembling the parts, the RFID tag 21 is also incorporated to complete the refrigerator. Then, in step 12, the refrigerator is turned on to inspect the finished product. Do. After the inspection is completed, a product label is attached to a normal refrigerator in Step 13 to complete Step 14 for completing the refrigerator. Thereafter, in step 15, device information including an ID number that enables individual identification of the refrigerator is written in the RFID tag 21. In this case, by bringing the dedicated terminal close to the RFID tag 21, the unique information is transmitted and written from the dedicated terminal to the RFID tag 21. Through the above process, the refrigerator is completed and shipped.

  In this way, by writing the device information to the RFID tag 21 when the product label is attached after the completion inspection of the refrigerator, the product label 23 and the RFID tag 21 can be incorporated as the same assembly part. Of device information can be eliminated. At the same time, there is an advantage that an empty number is not generated in the manufacturing number of the refrigerator. That is, the production number is usually given only to the refrigerator that has passed the inspection. For example, even if the product label described in the production number is pasted and the device information is written on the RFID tag 21, the finished product inspection is performed. The label 23 and the RFID tag 21 can be incorporated as the same assembly part. In this case, if the final inspection, which is a subsequent process, is rejected and rejected, an empty number is generated in the manufacturing number, Although complicated parts management remains, according to this embodiment, it is possible to prevent such a problem from occurring.

  Further, according to the above method, it is not necessary to turn on the refrigerator power and write the device information to the RFID tag 21 in the production process as in the prior art. Problems such as dew condensation and odor generation caused by refrigerator operation can be prevented and productivity is not reduced.

In the refrigerator of this embodiment, when the user purchases the refrigerator produced as described above and turns on the refrigerator to start use, the appliance information storage unit 30 of the refrigerator control unit A described later is used. (See FIG. 8) When the RFID tag 21 starts transmission / reception, the machine information written in the RFID tag 21 is written in the device information storage unit 30 and stored. That is, the device information is written only in the RFID tag 21 at the time of shipment, and the device information is not written in the refrigerator control unit A. However, the ID number is written only when the user purchases the refrigerator and turns on the power. Complete.

  Next, the configuration of the home appliance service system using the RFID tag 21 incorporated as described above will be described with reference to FIGS. FIG. 8 is a control block diagram showing a schematic configuration of the home appliance service system, and FIG. 9 is a flowchart for explaining the operation.

  In FIG. 8, the refrigerator control unit A includes a door opening / closing detection unit 25 that detects opening / closing of the door 11, a counting unit 26 that counts the number of times the door is opened / closed detected by the door opening / closing detection unit 25, and the counting unit 26 performs counting. A number storage unit 27 for storing the number of times, a time measuring unit 28 for measuring a door opening time when the door is opened and closed detected by the door opening / closing detection unit 25, a time storage unit 29 for cumulatively storing the time measured by the time measuring unit 28, and An RFID tag 21 is provided.

  As described above, device information including an ID number is written and stored in the RFID tag 21, and the device information is stored in the device information storage unit 30 of the refrigerator control unit A as will be described in detail later. It is written and retained. In this embodiment, the RFID tag 21 also serves as an output unit for the door opening / closing number information from the number storage unit 27 and the door opening accumulated time information from the time storage unit 29, and the antenna unit 21a is integrated. An IC chip or the like is used.

  Reference numeral 31 denotes a short-range communication detection unit that detects when a mobile terminal 22 such as a mobile phone, a smartphone, or a PDA approaches and requests information, and the RFID tag 21 itself is provided. It is designed to operate by supplying power. Therefore, when the portable terminal 22 approaches and requests information, the RFID tag 21 is activated by the short-range communication detection unit 31, and the latest door opening / closing stored in the ID number, the number-of-times storage unit 27, and the time storage unit 29 is performed. Information such as the number of times and the total door opening time is transmitted from the antenna unit 21a to the outside.

  On the other hand, the mobile terminal 22 uses a general mobile phone having a communication function, and its terminal control unit B has a first communication unit 32 that performs short-distance communication and its antenna 33 as well known for communication and Internet communication. The second communication unit 34 and its antenna 34a, the first and second communication control units 35 and 36 that control these communication units, the portable control unit 38 including the display control unit 37, the display unit 39 such as a liquid crystal display, It includes an operation unit 40 such as a touch switch, a storage unit 41, and the like. And when this portable terminal 22 switches to the short distance communication by the 1st communication control part 35 by operation of the operation part 40, while transmitting an information request signal to the other party and receiving the information from the other party, 2nd communication By operating the unit 34, the necessary information can be received by transmitting the information to the host computer of the service provider via the Internet line. At this time, in the present embodiment, the display control unit 37 can switch the display of the display unit 39 and display the information received by the first communication unit 32 on the display unit 39.

  The refrigerator equipped with an RFID tag configured as described above is such that when a component replacement is necessary due to a component failure, for example, a failure of the door 11b, the user brings the mobile terminal 22 close to the RFID tag 21, Device information including specific information such as the product number of the refrigerator can be received and transmitted to a service provider via an internet line via a portable terminal. Therefore, even an elderly person or a child can transmit a product number or the like without making a mistake, and an accurate repair service can be received.

  Hereinafter, a specific description will be given focusing on transmission and reception between the RFID tag 21 and the portable terminal 22 using the control flow of FIG. First, in the state where device information is stored and held in the RFID tag 21 as shown in step 1, it is checked in step 3 whether or not the short-range communication detection unit 31 has requested information. 1 day (24h) is checked, and if it has not passed, the process returns to step 2; if it has passed, the door opening / closing information stored in step 2 until then is reset in step 5; Return to 2.

  In this state, when the user transmits an information request signal by bringing the antenna 33 portion of the portable terminal 22 close to the RFID tag 21 of the refrigerator door (step 6), the short-range communication detection unit 31 detects this in step 3. The RFID tag 21 starts operation, and the RFID tag 21 opens and closes the device information in step 7 and the door opening and closing times such as the door opening and closing times stored in the number storage unit 27 and the time storage unit 29 in this embodiment and the door opening accumulated time. Information is acquired and transmitted in step 8. As a result, the portable terminal 22 receives the information at step 9 and transmits the information to the host computer of the service provider via the Internet line at step 10 or displays it on the display unit 39.

  As described above, the refrigerator in this embodiment obtains information by directly bringing the mobile terminal 22 close to the refrigerator itself that is the target device. Therefore, even an elderly person or a child is an ID that is unique device information such as a product number. The number can be received and transmitted to a service provider or the like without making a mistake so that an accurate repair service can be received.

  Further, since the RFID tag 21 has a receiving function, it is possible to prevent a case where a service provider replaces a component without noticing a component mistake. For example, when the door 11b is replaced, information is communicated between the door 11b and the refrigerator control unit A, and if there is a door mistake, this can be notified. By mistake of the product label 23 affixed to the door 11b, etc. It is possible to surely know the replacement mistakes that are likely to occur, and it is possible to prevent problems from occurring due to the replacement without noticing the part replacement mistake.

  Further, the user is caused to bring the portable terminal 22 close to the RFID tag 21, and for example, set temperature information for cooling is transmitted to the portable terminal 22 using the Internet line, and the set temperature information is transmitted from the portable terminal 22 to the RFID tag 21. The RFID tag 21 receives this and transmits it to the refrigerator control unit A to change the cooling set temperature.

  By the way, in the refrigerator of this embodiment, the door opening / closing information such as the door opening / closing frequency and the door opening accumulated time can be known by looking at the display unit 39 of the portable terminal 22 as described above. It becomes possible to promote power saving by reducing the number of times the door is opened and closed thereafter. In addition, the refrigerator does not require display power for notifying the user of the number of times the door is opened and closed, the total time of opening the door, and the like, so that power can be further saved and energy saving of the refrigerator is improved. That is, since this refrigerator can know the door opening / closing count and the door opening cumulative time via the display unit 39 of the portable terminal 22, the refrigerator itself uses electric power for displaying the door opening / closing count and the door opening cumulative time. There will be no consumption at all, and energy saving will proceed accordingly.

  Furthermore, in this embodiment, since the short-range communication detection unit 31 is provided on the refrigerator side and the short-range communication detection unit 31 detects that information is requested, the RFID tag 21 is fed to transmit information. Further, when there is no information request, the RFID tag 21 does not consume power, and energy can be further saved.

Further, in the refrigerator of this embodiment, the RFID tag 21 is provided on the door of the refrigerator compartment 2 that is the top of the refrigerator, that is, the uppermost door of the plurality of storage rooms, and therefore provided on the door located at the bottom. When the door above the door provided with the RFID tag 21 is opened, the cold air leaking down touches the RFID tag 21 to cause dew condensation on the surface, thereby deteriorating the communication state and component reliability. It does not cause problems such as decline in sex. Therefore, the door opening / closing frequency or time can be exchanged accurately and surely with the portable terminal 22, and a high-quality refrigerator can be obtained and the user can use it with peace of mind.

  Further, the RFID tag 21 is provided on a door corresponding to the refrigerator compartment 2 among a plurality of storage compartments, and the refrigerator compartment 2 has a higher internal temperature than the ice making compartment 3 and the freezer compartment 5. Can reduce the influence of. Therefore, the temperature difference between the surface and the inside of the RFID tag 21 can be suppressed to be small, and it is possible to suppress the occurrence of dew condensation, and it is possible to reduce troubles such as deterioration of communication state and deterioration of component reliability.

  Further, the RFID tag 21 is incorporated in the operation unit 18 provided at the end of the right door 11b, and even if a user sticks a posting to the door on a daily basis, the sticking is at the center of the door. In many cases, the surface of the RFID tag 21 located at the end of the door is rarely covered. Therefore, the user can directly face and approach the RFID tag 21 of the portable terminal 22, and information transmission / reception errors caused by bringing the portable terminal 22 close to the posted object are reduced, and the posted object that covers the surface of the RFID tag 21. It is not necessary to move the mobile terminal closer to paying off, ensuring reliable communication performance and improving usability.

  Further, the RFID tag 21 is provided on the right door 11b of the refrigerator compartment 2 as a double door, so that the occurrence of troubles due to the cool air inside the RFID tag 21 can be reduced. That is, there are many relatively right-handed users, and the right door 11b is frequently opened and closed by the right-handed user. However, when the right door 11b opens and the cool air leaks out. The cold air has a high possibility of diffusing to the surface of the left door 11a opposite to the right door 11b, up to the surface side of the right door 11b (the installation side of the RFID tag 21) on the back side as seen from the leaked cold air. There is very little possibility of going around. Therefore, there is almost no possibility of cold coming into contact with the RFID tag 21 provided on the right door 11b, and it is possible to suppress troubles such as deterioration of communication state and deterioration of component reliability caused by condensation on the surface. be able to.

  In particular, in this embodiment, since the right door 11b has a larger area than the left door 11a, the amount of cold air that tends to leak tends to increase, so the right door 11b on the side where this cold air leaks increases. By providing the RFID tag 21 on the side, the influence of the above-mentioned cold air is small, and there is less risk of deterioration of the communication state and part reliability, which is effective.

  In addition, the door provided with the RFID tag 21 is provided with wiring for sending door opening / closing information from the number storage unit 27 and the time storage unit 29 in the refrigerator control unit A together with wiring to the operation unit 18. All are DC wiring, and no AC wiring is provided on the door, so that noise generated from the AC wiring does not hinder the transmission of the RFID tag 21 and ensures more accurate and reliable communication performance. it can.

  Further, the right door 11b of the refrigerator compartment 2 provided with the RFID tag 21 is provided with an automatic door opening / closing mechanism 17 corresponding thereto, so that even if the user's hand working in the kitchen is wet with water, The obstacle of the RFID tag due to water can be reduced. That is, since the user only needs to touch the door lightly, water droplets attached to the door surface when the door is opened or closed are in a very small amount or not attached, and when the portable terminal 22 such as a mobile phone is brought close to the RFID tag 21, Water droplets adhering to the door surface can adhere to the RFID tag 21 itself or the portable terminal 22 approaching the RFID tag 21 to prevent the problem of soiling or getting wet, thereby preventing deterioration of communication state and component reliability. Obstacles such as decline in sex can be reduced.

  Further, since the RFID tag 21 is located away from the handle portion 16 provided on the door and is positioned above the handle portion 16, the user's hand is wet and this hand is used. Even if the door is opened and water droplets adhere to the handle portion 16, the RFID tag 21 is separated from the handle portion 16 and is located above the handle portion 16, so that it adheres to the handle portion 16. Even if the water drops spread left and right or sag, the RFID tag 21 is not disposed. Therefore, even if the portable terminal 22 approaches the RFID tag 21 as described above, It is possible to prevent problems such as the RFID tag 21 itself or the mobile terminal 22 approaching the RFID tag 21 being soiled or wetted by water droplets adhering to the surface of the unit 16, such as deterioration of communication state or deterioration of component reliability. It is possible to further reduce the harm.

  As described above, the refrigerator described in this embodiment can centrally manage product labels and RFID tags, and can prevent confusion due to device information mismatch. Is an embodiment for realizing the present invention, and various modifications can be made within the scope of achieving the object of the present invention.

  For example, as for the communication method, other short-distance wireless communication may be used as long as the target can be discriminated by a touch operation or an operation of holding the product.

  As described above, the present invention manages a plurality of parts to which product individual information is assigned as one sub-assembly part, so that the product label and the RFID tag can be managed in a unified manner, and the RFID tag that cannot be visually discriminated. The RFID tag can be easily managed, and the individual information assigned to the product label and the RFID tag is not different. An on-board refrigerator can be provided, which can be widely deployed for home and business use.
