The output unit of the control unit 2 is connected to a driving unit 6, a driving unit 8, and a display unit 12, respectively.

When this control device controls the temperature of the freezing room 15, a signal based on the detection result detected by the freezing room temperature detecting device 3 is input to the control means 2, and the control means 2 And / or determine the operation of the indoor blower 7.
A signal related to the determined operation of the compressor 5 or the indoor blower 7 is output to the driving means 6 and / or the driving means 8 to turn on / off the compressor 5 and / or the indoor blower 7. (For example, −18 ° C.) or less.

When controlling the temperature of the refrigerator compartment 16, a signal based on the detection result is input to the control means 2, and the control means 2 determines the operation of the compressor 5 and / or the indoor blower 7. A signal related to the determined operation of the compressor 5 and the indoor blower 7 is output to the driving unit 6 and / or the driving unit 8, and the compressor 5 and / or the indoor blower 7 is turned on and off, and the refrigerator compartment 1 is turned on.
6 is controlled to be lower than a predetermined indoor set temperature (for example, 3 ° C.).

When the freezer compartment door 23 or the refrigerator compartment door 24 is opened and closed, the freezer compartment door open / closed state detector 9 or the freezer compartment door open / closed state detector 10 detects the opening and closing operations of the door. Is transmitted to the control means 2. Further, the control means 2 recognizes the time by the time measuring means 2a, and measures the time when each door open / closed state detecting device is transmitting an open signal. After each door is closed, during a predetermined time (for example, 5 seconds), the temperature of the cooling chamber on the side where the door is opened and closed, detected by the freezing room temperature detecting device 3 or the refrigerator compartment temperature detecting device 4, Predetermined set temperature (for example: refrigerator room temperature = 5 ° C, freezer room temperature = -15 ° C)
When the above occurs (hereinafter referred to as an excessive temperature rise state),
The number of times the respective temperature rises of the freezer compartment door 23 and the refrigerator compartment door 24 have become excessive in the control means 2 (hereinafter referred to as excessive temperature rise times) is counted by a counting means provided in the control means 2, and the control means The number of excessive temperature rises counted for each door is stored in a storage means (not shown) provided in 2.

Next, the control operation of the control device 1 based on the excessive number of temperature rises of the refrigerator according to the present invention will be described with reference to the flowchart shown in FIG.

When the power is turned on, the control means 2 comprising a microcomputer is returned to the initial state, and the routine goes to step S1.

Thereafter, in step S1, the year, month, day, time, etc., such as the year of the Christian era, are set by inputting a signal from the timekeeping means 2a, and counting is started.
To read the first image (image 1) from the image group predetermined for the month and stored in the image storage unit 2b, and display the image 1 on the display unit 12 on the display unit 11. Output a signal. Thereby, the display means 12
Displays the image 1.

Then, in step S3, the freezer compartment door open / closed state detecting device 9 or the freezer compartment door open / closed state detecting device 10 detects whether the door is opened or not by judging whether or not the door is opened. If not, the judgment is repeated in this section until the door is opened.

Next, if at least one of the freezer compartment door 23 and the refrigerator compartment door 24 is open in step S3, it is determined in step S4 whether the door is closed, and the door is opened. If it is continued, it is repeatedly determined in this section until the door is closed. If the door is closed in step S4, the process proceeds to step S5.

Thereafter, in step S5, the room temperature of the cooling room whose door is opened and closed is detected by the freezing room temperature detecting device 3 and the refrigerator room temperature detecting device 4, and the detected room temperature is set to a predetermined set temperature (for example: If it is lower than the temperature of the refrigerator compartment = 5 ° C. and the temperature of the freezer compartment = −15 ° C.), the process proceeds to step S6, and the time that has elapsed since the door opened and closed in step S6 is closed for a predetermined time (for example, 5 (Seconds), the process returns to step S5, and steps S5 and S6 are repeated in the same manner as described above while the room temperature is lower than the predetermined set temperature and the elapsed time is shorter than the predetermined time.

If the room temperature detected in step S5 is equal to or higher than a predetermined set temperature (for example, refrigerator room temperature = 5 ° C. or freezer room temperature = −15 ° C.), the process proceeds to step S7. Then, in step S7, a month (for example,
(February, February, March...) Has changed to the next month, and if it is the same month as the month in which the number of excessive temperature rises was previously counted, the process proceeds to the next step shown in FIG.

Here, the relationship between FIG. 3 and FIG. 4 is that the code A in FIG. 3 is continuous with the code A in FIG.
Are continuous with the code B in FIG.

If the time elapsed in step S6 is equal to or longer than a predetermined time (for example, 5 seconds), the process proceeds to step S8, and in step S8, the month (for example, January, February, March,.
..) Is changed to the next month, and if it is the same month as the month in which the number of excessive temperature rises was previously counted, the process returns to step 3 and thereafter follows the same steps as described above.

If the next month is different from the month counted in step S8, the process proceeds to step S9. In step S9, the number of excessive temperature rises stored so far is deleted from the storage, and the process returns to step S2. Thereafter, the same steps as described above are followed.

In FIG. 4, the process proceeds from step S7 to step S10 in FIG.
Is stored separately, and then the step S11
It is determined whether or not the sum of the excessive number of temperature rises stored in (1) is equal to or greater than a first predetermined number (for example, 150 times). If the sum is equal to or greater than the first predetermined number, the process proceeds to step S12.

Thereafter, in step S12, step S1
It is determined whether or not the sum of the respective excessive temperature increases stored at 0 is equal to or greater than a second predetermined number (for example, 300 times).
If the number is less than the predetermined number, the process proceeds to step S13. From the display state of image 1 in step S13, the second image (image 2) is read out from the image group determined for the month, and image 2 is displayed on display unit 11. Is output on the display means 12. As a result, the image 2 is displayed on the display unit 12.

In step S12, step S10
It is determined whether or not the sum of the respective excessive temperature rise times stored in the step is equal to or greater than a second predetermined number (for example, 300 times).
At 14, the third image (image 3) is read from the image group determined for the month from the display state of image 2, and a signal for displaying image 3 on display means 12 is output to display unit 11. I do. Thereby, the image 3 is displayed on the display unit 12.

Then, it is determined whether or not the sum in step S11 is equal to or more than a first predetermined number of times (for example, 150 times).
If the number is less than the predetermined number, the process returns to step S8 in FIG. 3, and also returns to step S8 in FIG. 3 after displaying image 2 in step S13 or displaying image 3 in step S14.

It is to be noted that, in the image display, until the display of a different image is newly instructed, the immediately preceding image is continuously displayed.

The steps S7 and S8
When the “monthly change?” Is changed to “midnight has elapsed?” Or “one week has elapsed?” And the like, and the judgment criteria of the elapsed time and / or the count number are changed, the first predetermined number of times (for example: 5
Times or 35 times) and a second predetermined number of times (for example: 10 times or 7 times)
If it is changed to “0 times”, it can be changed to display the number of excessive temperature rises in one day or one week. This change is desirably configured so that the user can change it freely.

Then, the displayed image changes sequentially according to the number of excessive temperature rises taking into account the room temperature rise.
In each image displayed, the degree of excessive temperature rise is not only visually recognized in a step-by-step manner, but also in a step-by-step display in which the image has a story depending on the expression method of the image display (for example, a refrigerator is animated). Characters are gradually reduced from the wallet, gold coins are gradually reduced, etc.), and the number of excessive temperature rises increases. Being able to understand in a step-by-step manner the presence of an image serves as a warning.

In addition, a predetermined period (for example:
(Every month, every calendar month, every week, every 24 hours, etc.) Because the degree of excessive temperature rise taking into account the rise in room temperature is known, the awareness of the reduction of door opening / closing time, door opening / closing frequency or door opening / closing frequency is raised. As a result, the operating power of the refrigerator can be reduced, and a refrigerator that contributes to energy saving can be obtained.

Further, since the displayed images are sequentially changed by the step-by-step display having a story, the use becomes interesting and the refrigerator becomes more familiar, and the user can put food in and out. When you do, the sound of a melody or the like, which is common in the case of the sound source system that activates the sound source, is heard, and the temperature rise in the refrigerator compartment and the amount of electricity used are unconsciously noticed, so that the taking in and out of food is rushed Thus, a refrigerator having a display device that does not cause a potential discomfort to the user due to such stress can be obtained.

When a predetermined number of images are sequentially displayed at predetermined time intervals when the predetermined number of times is reached, not only the degree of excessive temperature rise can be visually recognized but also a warning Is further emphasized, and the displayed images are sequentially changed, which makes the use of the device more interesting, the refrigerator becomes more familiar, and the user does not have the discomfort that comes from the sound source method. A refrigerator having a display device is obtained. Further, if the image is made to blink at or above the predetermined number of excessive temperature rises, the meaning of the warning is further emphasized.

In the displayed image 1, image 2, and image 3, a story showing the growth process of the natural world (for example, image 1 = picture of an egg, image 2 = picture of a monster of a child, image 3 = grown With a monster picture), a refrigerator with a display device that can be used as a more familiar item can be obtained even more interesting to use.

The image group is determined for each month. By counting the time in step S1, if the next month changes, the image group becomes a different image group.
3 automatically changes, a plurality of images (image groups) to be displayed change as a predetermined period elapses,
Image group (eg January: sunrise, February: plum blossoming,
March: chicks grow, April: cherry blossoms bloom, May: carp streamers grow, June: snails grow larger,
, Etc.), a display device that can indicate the passage of a period such as a seasonal feeling at that time is provided to appeal to emotions, so that a more familiar refrigerator can be obtained.

Note that the image group is stored in March, June, September,
An image group (eg, March to May: tulip growth, chick growth,
June-August: More fish, more fireflies, 9
Mon-November: The number of maple leaves increases, the persimmon fruit becomes colored December-February: The snowman grows, rice cakes burn,
Etc.), the display will match the four seasons in Japan. Further, since the surrounding brightness is different between night and day, the brightness of the image may be adjusted to the surrounding conditions, the image may be partially blinked, or the image itself may be changed.

In step S4, it is determined whether or not the door is closed. If the door is kept open, the elapse of time from the opening of the door in step S3 is continued for a predetermined time (for example, 5 minutes) in the next step. ) Is determined, and when a predetermined time has elapsed, a warning state (for example: a screen is displayed on a warning image such as a blinking image or a warning message is displayed).
Warning sounds and voices flow out. Etc.) will alert you to the opening of the door, which will also reduce the operating power of the refrigerator,
Refrigerators that contribute to energy savings can be obtained.

As a modification of the above embodiment, step 5
And displaying the degree to which each room temperature has risen due to the opening operation of each door based on the detection result of step 6, so that the user can be notified of the degree of increase in the room temperature when the door is opened, and the user can open the door. Thus, it is possible to easily and specifically recognize how much the temperature inside the refrigerator has risen.
In addition, since it is possible to know a specific rise in the indoor temperature, the index serves as an index for the user to determine the timing of closing the door.

The above-mentioned display of the temperature rise includes a numerical display of the room temperature, a temperature display that changes stepwise (for example, a display using a color change that gradually changes from blue to red and a gradation), and the like. Conceivable. Also, a display using the animation as described above may be used.

Further, in the above flowchart, step S
5. If step S6 (FIG. 6) is eliminated, the number of times the door is opened / closed is counted every time the door is opened / closed, and the number of times the door is opened / closed can be managed.
If the setting of changing the display of No. 2 is set, it is possible to notify the user of the number of times of opening and closing the door without giving the user any potential discomfort by voice or the like. As a result, a refrigerator that contributes to labor saving of energy use can be obtained. However, when managing the number of times of opening and closing the door, the number of times of opening and closing the door is counted more than the number of times of excessive temperature rise, so that a setting change is required. For example, in the case where it is possible to change which of the number of times of opening and closing the door and the number of times of excessive temperature rise is displayed, it is necessary to change the count number.

When the number of times the door is opened and closed is controlled, the displayed image changes sequentially, so that the use of the refrigerator becomes more interesting and the refrigerator becomes more familiar and the user can use the sound source system. It is possible to provide a refrigerator that does not cause discomfort.

Further, when the image is displayed for a predetermined time (for example, 30 seconds) after the door is opened or closed, the trouble of displaying the image for a long time can be reduced. In addition, power consumption for display is reduced, and a refrigerator that contributes to energy saving can be obtained. Furthermore, regardless of the door opening / closing operation,
A setting may be made so that the image disappears automatically at midnight.

When the image is not displayed, other information or the like (for example, the temperature of each room by a temperature sensor or the like, the amount of ice stored in the ice storage unit measured by an ice storage lever or the like, or the information input in advance). If a video such as a landscape, a calendar for the month, a message board that allows pen input, etc.) are displayed on the display unit, a large amount of information can be displayed in a limited screen space.

The number of times of excessive temperature rise and the number of times of opening and closing the doors are the total of the numbers of times of both the freezing room door 23 and the refrigerator compartment door 24. The number of times of excessive temperature rise and the number of times of door opening / closing can be managed and notified more finely for each door by counting the number of times and displaying the results separately. Further, even when the number of storage rooms is three or more, the same devices as described above may be provided according to the respective requests according to the number thereof, and the displayed image may be a still image. The color may change even in the video.

Also, by rewriting the above-mentioned flowchart, the sum of the door opening / closing times stored in step S11 of FIG.
Times) or more. If the number is equal to or more than the predetermined number, the process proceeds to the next step. It is determined whether the flag F1 = 1. If the flag F1 is not 1, the image 2 is displayed in the next step. Proceed to the next step and set flag F1 = 1,
Go to step 8 in FIG.

Then, it is determined whether or not the sum of the respective door opening / closing counts stored in step S11 of FIG. 4 is equal to or greater than a predetermined count. If the sum is equal to or greater than the predetermined count, the process proceeds to the next step, and whether the flag F1 = 1 is satisfied. It is determined whether or not the flag F1 = 1, the image 3 is displayed in the next step, and then the process proceeds to step 8 in FIG.

Further, it is determined whether or not the sum of the door opening / closing times stored in step S11 of FIG. 4 is equal to or more than a predetermined number. If the sum is less than the predetermined number, the process proceeds to step 8 of FIG. Further, the process proceeds to step 8 in FIG. 3 and, unlike the previously counted month, if the next month has elapsed, the flag F1 is set to 0, and then the process proceeds to step S9. ), The image changes stepwise each time a predetermined number of times (for example: 150 times) has passed, and the step setting of the number of times of opening and closing the door is limited from the above-described flowchart, but this is also A refrigerator having the same effect can be obtained.

Further, the display means 11 is provided on the display unit 11 as described above.
The image displayed by may be a flower, a bird, other images (photos, illustrations, moving images, etc.), characters, numbers, patterns, colors, or a combination thereof. In the above description, the images are sequentially changed with respect to the images 1, 2, and 3. However, if the number of the images is increased or decreased as needed, simple management to detailed management can be performed.

In the above embodiment, the freezer 1
Although the case where 5 is above the refrigerating compartment 16 and one each is described, the number of freezing compartments and refrigerating compartments may be any, and the arrangement position of each cooling compartment is not particularly limited. A similar effect can be obtained by separately providing each of the above-described configurations of the temperature detecting device and the door opening / closing state detecting device and the like, and designing the control means 2 corresponding thereto to change the display on the display unit 11.

In order to notify the user, the displayed image will change according to the number of times the door is opened and closed, and the degree of the number of times the temperature in the room has risen excessively by the displayed image will not only be seen visually, but also In the image, the fact that the number of times has increased is gradually recognized as a warning, and the number of times of excessive temperature in the use state of the user is determined as to what is compared with the general use state. It can also be a guide. In addition, since the displayed image changes, the use of the refrigerator becomes more enjoyable and the refrigerator becomes more familiar, and it is possible to provide a refrigerator that does not give the user the discomfort that comes from the sound source system.

The control means 2 is configured to count both the number of times of opening and closing the door and the number of times of excessive temperature rise, and the control means 2 calculates the number of times of excessive temperature rise as a numerator by using the number of times of opening and closing the door as a denominator. If the user calculates the excessive number of temperature rises with respect to all the door opening and closing times as a percentage and displays the image displayed on the display unit in accordance with the ratio using the above-described display mode, the user opens and closes the door. You can know the tendency of usage during operation (whether the number of times of excessive temperature rise is more or less compared to general usage conditions), and the user does not receive potential stress when opening and closing the door The user is conscious of the energy loss, and the mode of use is improved.

Further, according to the present invention, it is possible to know the number of times the door is opened and closed or the number of times the temperature of the room has risen excessively in a predetermined period, and to compare the degree of the change in the predetermined period. This is a measure for suppressing the number of times the door is opened and closed and the number of times the room temperature is excessively increased during that period.
In addition, thereby, the user is conscious of the reduction of the frequency and the number of times during the period, the user is germinated, so that the operating power of the refrigerator can be reduced,
Refrigerators that contribute to energy savings can be obtained.

According to the present invention, since an image is displayed for a predetermined time after the door is opened or closed, not only the trouble of displaying the image is reduced, but also the power consumption is reduced and the energy consumption is reduced. A refrigerator that contributes to labor saving can be obtained.

Further, according to the present invention, since an image with a story is displayed, not only does the user not feel any potential stress, but also the user can use the refrigerator. And the number of times such images are viewed increases. Therefore, it is possible to more reliably report the number of times the door is opened and closed or the number of times the temperature in the room is excessively increased by an image, and further, it is possible to raise the user's awareness of the temperature rise due to the opening of the door. .

Further, according to the present invention, the growth process of a living thing or a character or a change in a natural phenomenon is displayed, so that it is possible to further attract the user's interest. The number of times that the temperature has risen excessively can be notified more reliably, and the user's awareness of the temperature rise due to the opening of the door can be raised.
