Description

  The present invention relates to a refrigerator with high energy saving performance.

  In general, refrigerators have a high power consumption ratio in the home, and there is a strong demand to suppress the power consumption as much as possible. For this reason, for example, there has been proposed a system in which the amount of power used is suppressed by automatically increasing the set temperature in the warehouse during the night when the user hardly opens and closes the door.

  In addition, since a lot of electric power is used to open and close the refrigerator door, the number of times the door is opened and closed, the time, etc. are measured in order to suppress this, and when the number of times the door is opened and closed reaches or exceeds a predetermined time, the display device It is configured to display a warning or a warning sound, notify the user of the increase in power usage due to opening and closing the door, reduce the number of times the door is opened and closed, and can be enlightened to reduce power usage (See, for example, Patent Document 1).

  FIG. 8 shows the refrigerator described in Patent Document 1. The door opening / closing detection means 101 measures the number of times the door 102 is opened and closed, the door opening / closing number is counted by the number counting means 103, and the control means 104 determines the number of times. The set number or the previous day's number stored in the door opening / closing number storage means 105 is compared, and when the door opening / closing number becomes equal to or more than the stored number, this is displayed on the display device 106 provided in the door 102 and the user opens / closes the door. It is configured to notify that the number of times has increased and to enlighten them to reduce the number of times the door is opened and closed.

JP 2002-147930 A

  However, in order to reduce the power consumption associated with the conventional door opening / closing, when the door opening / closing frequency reaches a predetermined number or more, this is notified for the first time to promote the reduction of the door opening / closing. It was not possible to know how many times the doors were opened and closed, and there was no desire to save electricity by reducing the number of doors that were opened and closed.

  However, recently, the safety of nuclear power generation has begun to be reviewed. As a result, there has been a shortage of power caused by shutting down the nuclear power plant, etc., so that users can save power by paying attention to how to use various devices such as refrigerators. In the refrigerator, the consciousness of reducing the number of times of opening and closing the doors has begun to grow before the power saving enlightenment notification as described above is issued.

  However, it is difficult for the user to know how much the door has been opened and closed in the morning, whether the number of times the door has been opened or closed today, and whether the cumulative time of opening the door is more or less than usual. Therefore, there is a problem that it is surprising that it is not possible to save power by reducing the number of times the door is opened and closed and the total opening time of the door even if there is awareness of power saving.

In order to solve this, it is conceivable to always display data such as the number of times the door is opened and closed and the total opening time of the door on the display device 106 provided in the refrigerator. Such a configuration is also considered from the user's standpoint. Since the displayed number of times of opening and closing the doors is cumulative from the morning, it is not possible to determine whether this number is large or small, for example, as a time zone for lunch preparation, and there is a concern that this does not lead to power saving. For example, the usage of a refrigerator is closely related to the eating habits pattern, and the door is opened and closed according to the meal time in the morning and evening. Although it is possible to compare the number of times the door is opened and closed in the connection with a specific mealtime period, it is not possible to determine whether the number of times the door is opened or closed in the current scene. Therefore, it is thought that it does not lead to trying to save electricity positively.

  The present invention has been made in view of the above points, and it is possible to know the number of times the door is opened and closed according to the eating habits pattern, and it is possible to effectively enlighten the person who reduces the number of times the door is opened and closed. The refrigerator which can be raised is provided.

  In order to solve the conventional problems, the present invention includes a refrigerator main body having a storage room, a door for opening and closing the storage room, a door opening / closing detection means for detecting opening / closing of the door, and the door opening / closing detection means. A time zone classification unit that classifies the detected door opening / closing frequency or door opening cumulative time for each time zone, and door opening / closing display means for displaying the door opening / closing frequency or door opening cumulative time divided by the time zone classification unit, The door opening / closing display means is configured to display a plurality of time zones divided by the time zone dividing section.

  As a result, the user can know the number of times the door opens and closes according to the eating habits putter, for example, the number of times the door opens and closes during breakfast hours compared to the number of times yesterday in the same time zone, etc. It is possible to know accurately, and it can be expected that the consciousness of reducing the number of times of opening and closing the doors effectively acts to reduce the number of times of opening and closing the doors.

  The present invention allows the user to know the number of times the door is opened / closed for each time zone according to the life pattern, and therefore, the consciousness to reduce the number of times the door is opened / closed effectively works to save power. Can be an energy-saving refrigerator.

  Hereinafter, door opening / closing display means for displaying data such as the number of times of opening / closing the door on the display unit of the portable terminal 22 will be described with reference to FIGS. FIG. 5 is a control block diagram showing the refrigerator control unit of the refrigerator and the portable control unit of the portable terminal, and FIG. 6 is a flowchart for explaining the control.

  In FIG. 5, 25 is the door opening / closing detection means, 26 is a frequency counting section for counting the number of door opening / closing times detected by the door opening / closing detection means 25, 27 is a 24-hour clock, and 28 is a time output from the 24-hour clock. In this embodiment, for example, the display is divided into four time zones: breakfast, lunch, dinner, and bedtime. For example, breakfast is set from 6:00 to 11:00, lunch from 11:00 to 16:00, dinner from 16:00 to 23:00, and at bedtime from 23:00 to 6:00. This is an example, and the time can be changed. In particular, if the user can set the time, the usability can be improved. A number storage unit 29 stores the number of times counted by the number counting unit 26. The number storage unit 29 stores the number of times from the number counting unit 26 for each time period based on the output from the time zone dividing unit 28. It is. Reference numeral 30 denotes a previous day data rewriting unit, which rewrites the number of times of opening and closing the door stored in the number of times storage unit 29 for each time zone after the lapse of 24 hours based on the time output from the 24-hour clock 27. Reference numeral 30A denotes a previous day data holding unit for storing and holding the rewrite data of the previous day count data rewriting unit 30. Reference numeral 21 denotes the data transmission unit described above, which serves as an output unit for the door opening / closing frequency data, and is constituted by an IC chip or the like integrated with the antenna unit 21A. The data transmission unit 21 displays the door opening / closing frequency data from the frequency storage unit 29 and the door opening / closing frequency data of the previous day from the previous day data holding unit 30A for each time zone.

  Reference numeral 31 denotes a short-range communication detection unit that detects data when a portable terminal 22 such as a mobile phone, a smartphone, or a PDA approaches and requests data. When a data request is detected, power is supplied to the data transmission unit 21 to operate it. It is supposed to let you. Therefore, when the portable terminal 22 approaches and requests data, the data transmission unit 21 is activated by the short-range communication detection unit 31, and the latest door opening / closing number data stored in the number storage unit 29 is received from the antenna 21A. It will be sent to the outside.

  On the other hand, the mobile terminal 22 uses a general mobile phone in this embodiment, and as is well known, a first communication unit 32 that performs short-range communication, its antenna 33, and a second communication unit 34 for telephone and Internet communication. And its antenna 34A, first and second communication control units 35 and 36 for controlling these communication units, a portable control unit 38 including a display control unit 37, a display unit 39 such as a liquid crystal display, and an operation unit such as a touch switch 40, a storage unit 41, and the like. And when this portable terminal 22 switches to the near field communication by the 1st communication control part 35 by operation of the operation part 40, while transmitting a data request signal to the other party and enabling reception of the data from the other party, the display control part 37 switches the display of the display unit 39 and displays the data received by the first communication unit 32 on the display unit 39, that is, the data transmission unit by bringing the antenna 33 of the first communication unit 32 closer to the data transmission unit 21 of the refrigerator. Data such as the number of times of opening and closing the door from 21 can be received and displayed on the display unit 39.

There are various short-distance communication means between the portable terminal 22 and the data transmission unit 21, and any of infrared communication, wireless LAN, Bluetooth (registered trademark), etc. may be used. Considering the use of mobile phones and smartphones, it is preferable to use short-range communication means for exchanging data such as phone numbers between mobile phones and smartphones, and this embodiment adopts this short-range communication method doing.

  In the above configuration, the operation will be described below using the control flow of FIG. First, when the user opens the door of the refrigerator, for example, the right door 11b of the refrigerator compartment 2 for taking in and out stored items, in step 1, the door open / close detection means 25 detects the door open / close and sends a signal to the frequency counting unit 26. S1 is output. In step 2, the count counter 26 increments the signal S1 by 1 and outputs it to the count storage 29. At that time, the frequency counting unit 26 determines the time zone in step 3 based on the time zone determination signal from the time zone dividing unit 28, and stores the number of times in the time zone, that is, the +1 number S2 in step 4. Then, in step 5, it is confirmed whether or not the near field communication detection unit 31 has requested data. If there is no request, it is confirmed in step 6 whether one day (24h) has passed. When the time has elapsed, the number of times of opening and closing the door that has been stored so far is reset in step 7, and the process returns to step 1.

  In this state, when the user transmits the data request signal by bringing the antenna 33 portion of the mobile terminal 22 close to the data transmission unit 21 of the refrigerator door (step 8), the short-range communication detection unit 31 detects this in step 5. Then, the data transmission unit 21 starts its operation, and the data transmission unit 21 acquires the number of door opening / closing times stored in the number storage unit 29 in step 9 and transmits the data in step 10. For example, if the time zone when the portable terminal 22 is brought close is a breakfast time zone, the number of doors opened and closed on that day and the number of doors opened and closed on the previous day after the start of the breakfast time zone are acquired and the data is transmitted. Thereby, the portable terminal 22 receives the data at step 11 and displays the data on the display unit 39 at step 12.

  Therefore, the user can know the number of times of opening and closing the door during the meal time period by looking at the display unit 39, and when the number of times is large, the user is careful to reduce the number of times of opening and closing the door, and power saving is promoted. become. In particular, the display unit 39 displays each time zone, for example, the number of breakfast hours if it is a breakfast time zone, so that the number of times of the breakfast time zone can be accurately grasped. You can know exactly whether the door opening and closing times during breakfast hours are high or low. Moreover, the number of times can be known in comparison with the previous day. That is, since the number of times in the same time zone on the current day and the previous day is displayed, the user can accurately grasp the increase / decrease in the same time zone compared to the previous day, which is effective.

  In addition, since the door opening / closing frequency is displayed on the portable terminal side, the display device for door opening / closing display is abolished on the refrigerator side, or the door opening / closing frequency reaches a predetermined number even if a display device is provided. It is only necessary to enlighten to the extent that this is notified, and the power consumption of the refrigerator itself can be suppressed. In particular, in this embodiment, the display device for notifying the number of times the door is opened and closed on the refrigerator side is eliminated, and the display power for notifying the user of the number of times the door is opened and closed is not required. , Energy saving in the refrigerator is improved.

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

  In addition, in this embodiment, the Internet line can be used via the second communication unit 34 of the mobile terminal 22, and the number of times the door is opened and closed can be displayed, for example, on a personal computer of the company. It is possible to call attention to reduce the opening and closing of the door by contacting the family.

  In addition, in the refrigerator of this embodiment, since the data transmission part 21 is provided in the most convex part of the door surface, the portable terminal 22 can be made to approach or contact the data transmission part 21, and reliable communication performance is ensured. In addition, the exterior of the door around the data transmission unit 21 is not damaged by the mobile terminal, and the appearance of the exterior of the door can be maintained well over a long period of time.

  In addition, since the data transmission unit 21 is provided at the door of the storage chamber 2 that is the top of the refrigerator, that is, the uppermost door of the plurality of storage chambers, the obstacle as in the case of being provided at the door located at the lower part That is, the cold air that leaks down when the door above the door provided with the data transmission unit 21 is opened touches the data transmission unit 21 to cause condensation on the surface, thereby deteriorating the communication state, lowering the component reliability, etc. Will not cause any trouble.

  In addition, the data transmission unit 21 is provided on a door corresponding to the refrigerator compartment 2 among the plurality of storage rooms, and the refrigerator compartment 2 has a higher internal temperature than the ice making compartment 3 and the freezer compartment 5. The influence of cold air can be reduced. Therefore, the temperature difference between the surface and the inside of the data transmission unit 21 can be suppressed to be small, the occurrence of dew condensation can be suppressed, and obstacles such as deterioration of communication state and deterioration of component reliability can be reduced.

  Further, the data transmission unit 21 is incorporated in the operation unit 18 provided at the end of the right door 11b, and this is the data transmission even when the posting of the posting to the door that is performed on a daily basis by the user is in the central portion of the door. There is little possibility of causing a communication failure by covering the surface of the unit 21, and reliable communication performance can be ensured.

  Further, the data transmission unit 21 is provided on the right door 11b having a large area of the storage chamber 2 which is a double door, and the occurrence of a failure due to the cool air inside the data transmission unit 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, and the surface side of the right door 11b on the back side when viewed from the leaked cold air (installation side of the data transmission unit 21) There is very little possibility of going around. Therefore, there is almost no possibility of cold air coming into contact with the data transmission unit 21 provided on the right door 11b, and it is possible to suppress failures such as deterioration of communication state and deterioration of component reliability caused by condensation on the surface. can do. This is effective because more cold air leaks when a door with a large area is opened.

  In addition, since the door provided with the data transmission unit 21 is not provided with an AC wiring with only a DC wiring, noise generated from the AC wiring does not interfere with the transmission of the data transmission unit 21, and more accurately and accurately. Secure communication performance can be ensured.

  In addition, the right door 11b of the storage chamber 2 provided with the data transmission unit 21 is provided with an automatic door opening / closing mechanism 17 correspondingly, and the data transmission unit is located away from the handle 16 and Since it is arranged at a position above the handle portion 16, even if the door is touched with a wet hand, the amount of water on the wet hand that adheres to the door is small, and it is far from the data transmission unit. The data receiving unit is not wetted by water, and troubles such as deterioration of communication state and deterioration of component reliability can be reduced.

(Embodiment 2)
FIG. 7 shows the second embodiment. In the second embodiment, the door opening / closing display means 43 is provided on the door 11b of the refrigerator main body 1. From the door opening / closing number data from the number storage unit 29 and the previous day data holding unit. The door opening / closing frequency data of the previous day is displayed for each time zone.

  Therefore, also in this second embodiment, as in the first embodiment, the user looks at this door opening / closing display means 43 for each time zone, for example, if it is a breakfast time zone, It can be known with the number of times, and when the number of times is large, power saving will be promoted by taking care to reduce the number of times of opening and closing the doors thereafter.

  As described above, the refrigerator described in this embodiment can appropriately display the number of times of opening and closing the door and can promote energy saving. However, what has been described in the above embodiment is a form for realizing the present invention. There are various modifications within the scope of the object of the present invention.

  For example, in the above embodiment, the data provided to the user for the energy saving enlightenment is the door opening / closing frequency, but this may be the door opening accumulated time or both.

  In addition, the time zone section 28 is divided into four time zones: breakfast (6am to 12:00), lunch (12:00 to 18:00), dinner (18:00 to 24:00), and bedtime (24:00 to 6am). Although it is configured to be displayed separately, this may be divided into two time zones, daytime and nighttime, and a bedtime zone may be added to each of these time zones to classify them. Even in this case, it is possible to accurately know the number of times the door is opened and closed in each time period, and to effectively exhibit the power saving effect. In particular, it is possible to analyze those that display the sleeping hours by dividing them, such as the number of times the door is opened and closed during the sleeping hours, and it is possible to encourage the family to reduce the number of times the door is opened and closed. Power saving effect can be enhanced.

  Moreover, although the data transmission part 21 demonstrated with the case of only the transmission function, as a transmission / reception part with a reception function, setting temperature data can be set to the data transmission part 21 by transmitting from the portable terminal 22 side to the data transmission part 21, for example Or the door opening / closing frequency data from the refrigerator control unit may be received by short-range wireless communication instead of wiring.

  Furthermore, in the case of a transmission / reception unit having a transmission / reception function, a transmission / reception unit is provided on the refrigerator main body side in correspondence with the transmission / reception unit provided on the door, and the transmission / reception unit on the refrigerator main body side detects this when the door is opened, That is, the door transmission / reception unit may also be used as the door opening / closing detection means, thereby simplifying the configuration. The door opening / closing detection means is preferably provided corresponding to all the doors, but may be provided, for example, at one or several doors with high opening / closing frequency.
