Detailed Description

(first embodiment)

A refrigerator (an example of a home appliance) according to an embodiment will be described with reference to the drawings. As shown in fig. 1, a refrigerator 10 according to an embodiment includes a refrigerator main body 11. The refrigerator main body 11 includes a refrigerating chamber 14 for refrigerating food items, a freezing chamber 15 for freezing food items, and the like. The refrigerator main body 11 includes a compressor, a fan, and the like (both not shown).

The refrigerator main body 11 is provided with a rotary door 12. Door 12 opens and closes a front opening of refrigerating compartment 14. The door 12 is provided with a display operation unit 13. The display operation unit 13 is, for example, a touch panel. The display operation unit 13 includes a liquid crystal panel 18 and a backlight 19 provided on a rear surface of the liquid crystal panel 18. The display operation portion 13 can display various information related to the refrigerator 10. For example, the display operation unit 13 can display the open/close state of the door 12 and the temperatures of the refrigerating compartment 14 and the freezing compartment 15. The display operation unit 13 can accept various user operations related to the refrigerator 10. For example, the display operation unit 13 can receive a user operation for adjusting the temperature of the refrigerating room 14 and the freezing room 15.

As shown in fig. 2, the refrigerator 10 includes a control unit 30 and a storage unit 31. The control unit 30 includes a CPU, for example. The control unit 30 controls the operation of the refrigerator 10 based on the control program stored in the storage unit 31. For example, the control unit 30 controls the operation of a compressor and a fan of the refrigerator 10. The storage unit 31 includes, for example, a ROM and a RAM. The storage unit 31 stores a control program for controlling the operation of the refrigerator 10.

Next, a screen display process performed in the above-described refrigerator 10 will be described. Fig. 3 is a flowchart of screen display processing according to an embodiment. The screen display processing is started when the power of the refrigerator 10 is turned on, for example. As shown in fig. 3, in S10 of the screen display process, the control unit 30 of the refrigerator 10 determines whether or not the display operation unit 13 is operated. When the display operation unit 13 is operated, the control unit 30 determines yes and proceeds to S11. Otherwise, control unit 30 determines no and proceeds to S12. For example, when the user of refrigerator 10 touches and operates display operation unit 13 to adjust the temperature of refrigerating room 14, control unit 30 determines "yes" at S10. On the other hand, when the display operation unit 13 is not touch-operated, the control unit 30 determines no in S10.

In S11 after yes in S10, the control unit 30 displays the operation state screen 41 (see fig. 4) on the display operation unit 13. The operation state screen 41 is a screen showing that the display operation unit 13 is operated. The configuration of the operation state screen 41 is not particularly limited. For example, when the user of refrigerator 10 operates display operation unit 13 to adjust the temperature of refrigerating room 14, operation state screen 41 is a screen for adjusting the temperature of refrigerating room 14 as shown in fig. 4. In addition, the operation state screen 41 may be a screen for setting the operation mode of the refrigerator 10, for example. For example, the operation state screen 41 may be a screen for setting a power saving mode for saving power consumption of the refrigerator 10, a screen for setting a rapid cooling mode for rapidly cooling food items stored in the freezing chamber 15, or the like. The operation state screen 41 may be a screen corresponding to the content of the operation on the display operation unit 13. The background color of the operation state screen 41 is, for example, black. The control unit 30 displays, for example, a black screen on the display operation unit 13 as a background screen of the operation state screen 41. When the process of S11 shown in fig. 3 is finished, control unit 30 returns.

In S12 after no in S10, control unit 30 determines whether or not a predetermined time has elapsed since display operation unit 13 was not operated. The predetermined time is, for example, 3 minutes. If the predetermined time has elapsed (that is, if the display operation unit 13 has not been operated for the predetermined time), the control unit 30 determines yes and proceeds to S13. Otherwise, control unit 30 determines no and returns to S10. If the user of refrigerator 10 does not operate display operation unit 13 for a predetermined time, control unit 30 determines "yes". In this case, the control unit 30 is in a standby state. On the other hand, when the user operates the display operation unit 13 before the predetermined time elapses, the control unit 30 determines no.

In S13 after yes in S12, controller 30 displays standby state screen 42 (see fig. 5) on display operation unit 13. The standby state screen 42 is a screen different from the operation state screen 41 (see fig. 4). The standby state screen 42 is a screen showing that the operation unit 13 is not operated and is in a standby state. The configuration of the standby state screen 42 is not particularly limited. For example, the standby state screen 42 may be a screen indicating the brand name of the refrigerator 10 as shown in fig. 5. Alternatively, the standby state screen 42 may be a landscape screen or an animal screen, for example. The standby state screen 42 may be a moving image other than a still image. When the process of S12 shown in fig. 3 is finished, control unit 30 returns. Then, the control unit 30 repeats the screen display processing described above.

When the standby state screen 42 is displayed on the display operation unit 13 in S13 described above, the control unit 30 may display the background color on the display operation unit 13. Next, a background color display process performed in the above-described refrigerator 10 will be described. Fig. 6 is a flowchart of a background color display process according to an embodiment. The background color display processing is started, for example, at the same time as the processing of S13 (see fig. 3) described above. As shown in fig. 6, in S20 of the background color display process, the control section 30 determines whether or not the state of the refrigerator main body 11 is an abnormal state. If the state of the refrigerator main body 11 is the abnormal state, the control unit 30 determines yes and proceeds to S21. Otherwise, control unit 30 determines no and proceeds to S22. The criterion for determining whether or not the state of the refrigerator main body 11 is abnormal is not particularly limited. For example, control unit 30 may determine whether or not the state of refrigerator main body 11 is an abnormal state based on the detected temperature of a thermistor (not shown) that detects the temperature of refrigerating room 14. When the temperature detected by the thermistor is abnormally high, the control unit 30 determines that the state of the refrigerator main body 11 is an abnormal state. When the temperature detected by the thermistor is within the normal range, the control unit 30 determines that the state of the refrigerator main body 11 is not abnormal. For example, the control unit 30 may determine whether or not the state of the refrigerator main body 11 is an abnormal state based on an operation sound of the compressor of the refrigerator main body 11.

In S21 after yes in S20, control unit 30 displays the first background color on display operation unit 13. The first background color is a color indicating that the state of the refrigerator main body 11 is an abnormal state. A first background color indicating an abnormal state is set in advance. The first background color is, for example, red. The control unit 30 displays, for example, a red screen as a background screen of the standby screen 42 on the display operation unit 13. When the process at S21 ends, control unit 30 returns.

In S22 after no in S20 described above, control unit 30 determines whether or not the state of refrigerator main body 11 is a power saving state. If the state of the refrigerator main body 11 is the power saving state, the control unit 30 determines yes and proceeds to S23. If the operation mode of the refrigerator 10 is set to the power saving mode and the refrigerator 10 is operating in the power saving mode, the control unit 30 determines yes. Otherwise, control unit 30 determines no and proceeds to S24. The control section 30 can determine whether or not the state of the refrigerator main body 11 is the power saving state by monitoring the power consumption of the refrigerator main body 11, for example.

In S23 after yes in S22, control unit 30 displays the second background color on display operation unit 13. The second background color is a color indicating that the state of the refrigerator main body 11 is in the power saving state. A second background color indicating a power saving state is set in advance. The second background color is, for example, green. The control unit 30 displays, for example, a green screen as a background screen of the standby state screen 42 on the display operation unit 13. When the process at S23 ends, control unit 30 returns.

If no in S22, control unit 30 determines that the state of refrigerator main body 11 is the normal state. In the present embodiment, a case where the state of the refrigerator main body 11 is neither an abnormal state nor a power saving state is assumed to be a normal state. The normal state is a state in which the refrigerator 10 is operating without problems. In S24 after no in S22, control unit 30 displays the third background color on display operation unit 13. The third background color is a color indicating that the state of the refrigerator main body 11 is in a normal state. The third background color indicating the normal state is set in advance. The third background color is, for example, blue. The control unit 30 displays, for example, a blue screen as a background screen of the standby screen 42 on the display operation unit 13. When the process at S24 ends, control unit 30 returns. Then, the control unit 30 repeats the background color display processing described above.

As is apparent from the above description of the refrigerator 10 according to the embodiment, the refrigerator 10 includes the refrigerator main body 11, the display operation unit 13 provided in the refrigerator main body 11, and the control unit 30. The controller 30 displays the operation state screen 41 (see fig. 4) on the display operation unit 13 (see S10 and S11 in fig. 3) when the display operation unit 13 is in the operation state in which the display operation unit 13 is operated, and displays the standby state screen 42 (see fig. 5) having a display mode different from that of the operation state screen 41 on the display operation unit 13 (see S12 in fig. 3) when the display operation unit 13 is in the standby state in which the display operation unit 13 is not operated. According to this structure, since the user of the refrigerator 10 viewing the display operation portion 13 can easily distinguish the operation state from the standby state, the state of the refrigerator 10 can be easily recognized.

In the above-described refrigerator 10, the control unit 30 displays one background color selected according to a predetermined condition from among a plurality of background colors (for example, red, green, and blue) on the display operation unit 13. When the standby state screen 42 (see fig. 5) is displayed on the display operation unit 13, the control unit 30 displays a background color corresponding to the state (for example, the abnormal state, the power saving state, and the normal state) of the refrigerator main body 11 on the display operation unit 13 (see S13 and fig. 6 of fig. 3). When the state of the refrigerator main body 11 is abnormal, the controller 30 displays a background color (for example, red) indicating that the state is abnormal on the display operation unit 13 when the standby state screen 42 (see fig. 5) is displayed on the display operation unit 13 (see S20 and S21 of fig. 6). When the state of the refrigerator main body 11 is the power saving state, the controller 30 displays the background color (for example, green) indicating that the power saving state is achieved on the display operation unit 13 when the standby state screen 42 (see fig. 5) is displayed on the display operation unit 13 (see S22 and S23 of fig. 6). When the state of the refrigerator main body 11 is the normal state, the control unit 30 displays the background color (for example, blue) indicating the normal state on the display operation unit 13 when the standby state screen 42 (see fig. 5) is displayed on the display operation unit 13 (see S24 in fig. 6). According to this structure, the user of the refrigerator 10 can easily recognize the state of the refrigerator 10 from the background color displayed on the display operation part 13. The user can easily recognize the state of the refrigerator 10 even from a place far from the refrigerator 10.

While one embodiment has been described above, the specific embodiment is not limited to the above embodiment. In the following description, the same reference numerals are given to the same components as those in the above description, and the description thereof is omitted.

(second embodiment)

A second embodiment will be explained. In the first embodiment described above, the first background color (red) corresponding to the abnormal state of the refrigerator main body 11, the second background color (green) corresponding to the power saving state, and the third background color (blue) corresponding to the normal state are set in advance. However, the present invention is not limited to this configuration. In the second embodiment, there may be a configuration in which the user of the refrigerator 10 can select the first background color corresponding to the abnormal state, the second background color corresponding to the power saving state, and the third background color corresponding to the normal state. The user of the refrigerator 10 may be able to select the first background color, the second background color, and the third background color by operating the display operation unit 13. The display operation unit 13 is configured to be able to accept a user operation for selecting a background color. For example, the user of the refrigerator 10 can select a brown color as the first background color, a yellow color as the second background color, and a green color as the third background color by performing a touch operation on the display operation section 13.

When the background color display processing shown in fig. 6 is executed, the control unit 30 displays the background color selected by the user on the display operation unit 13. For example, when the first background color corresponding to the abnormal state is displayed in S21, the control section 30 displays the first background color of the brown color selected by the user. In addition, when the second background color corresponding to the power saving state is displayed in S23, the control unit 30 displays the second background color of yellow selected by the user. In addition, when the third background color corresponding to the normal state is displayed in S24, the control unit 30 displays the third background color of green selected by the user.

The second embodiment has been explained above. As is apparent from the above description, in the second embodiment, when the standby state screen 42 (see fig. 5) is displayed on the display operation unit 13, the control unit 30 displays the background color, which is selected in advance by the user in accordance with the state of the refrigerator main body 11, on the display operation unit 13 (see S21, S23, and S24 of fig. 6). For example, when the first background color corresponding to the abnormal state is displayed in S21, the control section 30 displays the first background color of the brown color selected by the user. According to this configuration, since the background color selected by the user is displayed on the display operation portion 13, the user of the refrigerator 10 who views the display operation portion 13 can easily recognize the state of the refrigerator 10. If the user of the refrigerator 10 is, for example, abnormal color vision, the background color may not be distinguished by a normal setting. However, if the configuration is such that the user can select the background color, the user can select the background color that can be distinguished by himself/herself, and therefore, the background color displayed on the display operation unit 13 can be distinguished. Therefore, even in the case where the user has abnormal color vision, the state of the refrigerator 10 can be easily recognized.

(third embodiment)

A third embodiment will be explained. In the third embodiment, the control unit 30 may display a selection screen 50 for selecting a combination of a plurality of background colors on the display operation unit 13 as shown in fig. 7. The selection screen 50 displays a plurality of combinations A, B, C. Each combination A, B, C includes multiple colors. Each combination A, B, C is a combination of a plurality of background colors. In addition, the selection screen 50 displays a plurality of states of the refrigerator main body 11. For example, the selection screen 50 displays an abnormal state, a power saving state, and a normal state. The selection screen 50 displays a plurality of combinations of a plurality of background colors corresponding to a plurality of states (abnormal state, power saving state, and normal state) of the refrigerator main body 11, respectively. In the present embodiment, the combination a specifies red, green, and blue as background colors corresponding to the abnormal state, the power saving state, and the normal state, respectively. The combination B defines brown, yellow, and green as background colors corresponding to the abnormal state, the power saving state, and the normal state, respectively. The combination C defines purple, blue, and orange as background colors corresponding to the abnormal state, the power saving state, and the normal state, respectively. Note that, although colors are shown by characters in fig. 7 for convenience, a color screen is actually shown instead of characters.

In the refrigerator 10 described above, the user can select any one combination from the plurality of combinations A, B, C shown in fig. 7 by operating the display operation unit 13. For example, the user can select the combination B by touching a button of the combination B displayed on the display operation unit 13. If the combination B is selected, the brown color is selected as the background color of the abnormal state, the yellow color is selected as the background color of the power saving state, and the green color is selected as the background color of the normal state.

When the background color display processing shown in fig. 6 is executed, the control section 30 of the refrigerator 10 displays the background color on the display operation section 13 based on the combination selected by the user. When the background color is displayed on the display operation unit 13, the control unit 30 displays the background color included in the combination selected by the user. For example, when the combination B shown in fig. 7 is selected and the first background color corresponding to the abnormal state is displayed in S21 shown in fig. 6, the control unit 30 displays the first background color of brown. In addition, when the second background color corresponding to the power saving state is displayed in S23, the control unit 30 displays the second background color of yellow. In addition, when the third background color corresponding to the normal state is displayed in S24, the control unit 30 displays the third background color of green.

The third embodiment is explained above. As is apparent from the above description, in the third embodiment, the control unit 30 displays the selection screen 50 on the display operation unit 13 (see fig. 7) capable of selecting an arbitrary combination from a plurality of combinations (for example, the combination A, B, C) of background colors defining the background colors corresponding to the plurality of states (for example, the abnormal state, the power saving state, and the normal state) of the refrigerator main body 11. When the display operation unit 13 is operated to select an arbitrary combination (for example, combination B) from among combinations of a plurality of background colors, the controller 30 displays, on the display operation unit 13, the background color corresponding to the state of the refrigerator main body 11 among the plurality of background colors (for example, brown, yellow, and green) included in the selected combination (see S21, S23, and S24 of fig. 6). According to this configuration, since the background color selected by the user is displayed on the display operation portion 13, the user of the refrigerator 10 who views the display operation portion 13 can easily recognize the state of the refrigerator 10. In addition, the user can select a combination of easily distinguishable background colors.

(fourth embodiment)

A fourth embodiment will be explained. In each of the above embodiments, when the standby state screen 42 is displayed on the display operation unit 13, the control unit 30 changes the background color in accordance with the state of the refrigerator main body 11. However, the present invention is not limited to this configuration. In the fourth embodiment, the control section 30 may change the standby state screen 42 itself according to the state of the refrigerator main body 11. In the fourth embodiment, the standby state screen display processing shown in fig. 8 is executed. The processing of S20 and S22 in the standby state screen display processing is the same as the processing of S20 and S22 in the background color display processing (see fig. 6), and therefore, detailed description thereof is omitted. In the standby state screen display processing, the processing of S31, S33, and S34 is executed instead of the processing of S21, S23, and S24 in the background color display processing (see fig. 6).

At S31 shown in fig. 8, the control unit 30 displays the first standby state screen 42a (see fig. 5) on the display operation unit 13. The control section 30 displays the first standby state screen 42a in accordance with the fact that the state of the refrigerator main body 11 is the abnormal state (yes in S20). The first standby state screen 42a is a screen showing that the state of the refrigerator main body 11 is in an abnormal state. The first standby state screen 42a indicating an abnormal state is set in advance. The first standby state screen 42a is a screen indicating the brand name of the refrigerator 10, for example, as shown in fig. 5. When the process of S31 shown in fig. 8 is finished, control unit 30 returns.

At S33 shown in fig. 8, the control unit 30 displays the second standby state screen 42b (see fig. 9) on the display operation unit 13. The control section 30 displays the second standby state screen 42b in accordance with the state of the refrigerator main body 11 being the power saving state (yes in S22). The second standby state screen 42b is a screen indicating that the state of the refrigerator main body 11 is in the power saving state. The second standby state screen 42b indicating the power saving state is set in advance. The second standby state screen 42b is a screen of a landscape, for example, as shown in fig. 9. When the process of S33 shown in fig. 8 is finished, control unit 30 returns.

At S34 shown in fig. 8, the control unit 30 displays the third standby state screen image 42c (see fig. 10) on the display operation unit 13. The control section 30 displays the third standby state screen 42c in response to the state of the refrigerator main body 11 being the normal state (no in S22). The third standby state screen 42c is a screen showing that the state of the refrigerator main body 11 is in a normal state. The third standby state screen 42c indicating the normal state is set in advance. The third standby state screen 42c is, for example, a screen of an animal as shown in fig. 10. When the process of S34 shown in fig. 8 is finished, control unit 30 returns.

The fourth embodiment has been explained above. As is apparent from the above description, in the fourth embodiment, the control unit 30 displays one standby state screen 42 selected according to a predetermined condition from among the plurality of standby state screens 42 (for example, a brand name screen, a landscape screen, and an animal screen) on the display operation unit 13. The control unit 30 displays a standby state screen 42 corresponding to the state (for example, an abnormal state, a power saving state, and a normal state) of the refrigerator main body 11 on the display operation unit 13 (see fig. 8). With this configuration, the user of the refrigerator 10 can easily recognize the state of the refrigerator 10 on the basis of the standby state screen 42 displayed on the display operation unit 13.

(fifth embodiment)

A fifth embodiment will be explained. In the fourth embodiment described above, the first standby state screen 42a (brand name screen) corresponding to the abnormal state of the refrigerator main body 11, the second standby state screen 42b (landscape screen) corresponding to the power saving state, and the third standby state screen 42c (animal screen) corresponding to the normal state are set in advance. However, the present invention is not limited to this configuration. In the fifth embodiment, there may be a configuration in which the user of the refrigerator 10 can select the first standby state screen 42a corresponding to the abnormal state, the second standby state screen 42b corresponding to the power saving state, and the third standby state screen 42c corresponding to the normal state. The user of the refrigerator 10 may select the first standby state screen 42a, the second standby state screen 42b, and the third standby state screen 42c by operating the display operation unit 13. The display operation unit 13 is configured to be able to accept a user operation for selecting the standby state screen 42. For example, the user of the refrigerator 10 can select a screen of an animal as the first standby state screen 42a, a screen of a brand name as the second standby state screen 42b, and a screen of a landscape as the third standby state screen 42c by performing a touch operation on the display operation unit 13.

When executing the standby state screen display processing shown in fig. 8, the control unit 30 displays the standby state screen 42 selected by the user on the display operation unit 13. For example, when the first standby state screen 42a corresponding to the abnormal state is displayed in S31, the control section 30 displays the screen of the animal selected by the user. When the second standby state screen 42b corresponding to the power saving state is displayed in S23, the control unit 30 displays a screen of the brand name selected by the user. When the third standby state screen image 42c corresponding to the normal state is displayed in S24, the control unit 30 displays the screen image of the landscape selected by the user.

The fifth embodiment has been described above. As is apparent from the above description, in the fifth embodiment, when the standby state screen 42 is displayed on the display operation unit 13, the control unit 30 displays the standby state screen 42, which is selected in advance by the user in accordance with the state of the refrigerator main body 11, on the display operation unit 13 (see S31, S33, and S34 of fig. 8). For example, when the first standby state screen 42a corresponding to the abnormal state is displayed in S31, the control section 30 displays the screen of the animal selected by the user. According to this configuration, since the standby state screen 42 selected by the user is displayed on the display operation portion 13, the user of the refrigerator 10 viewing the display operation portion 13 can easily recognize the state of the refrigerator 10.

(sixth embodiment)

A sixth embodiment will be explained. In the third embodiment described above, the control unit 30 displays the selection screen 50 for selecting a combination of a plurality of background colors on the display operation unit 13 as shown in fig. 7, but the configuration is not limited to this. In the sixth embodiment, the control unit 30 may display a selection screen 60 for selecting a combination of a plurality of standby state screens 42 on the display operation unit 13 as shown in fig. 11. The selection screen 60 displays a plurality of combinations D, E, F. Each combination D, E, F includes multiple pictures. Each combination D, E, F is a combination of a plurality of standby state screens 42. In addition, the selection screen 60 displays a plurality of states of the refrigerator main body 11. For example, the selection screen 60 displays an abnormal state, a power saving state, and a normal state. The selection screen 60 displays a plurality of combinations of the plurality of standby state screens 42 corresponding to a plurality of states (abnormal state, power saving state, and normal state) of the refrigerator main body 11, respectively. In the present embodiment, the screen D for specifying the brand name, the screen for scenery, and the screen for animals are combined as the standby state screen 42 corresponding to each of the abnormal state, the power saving state, and the normal state. The screen specifying the animal, the screen specifying the brand name, and the screen specifying the scenery are combined to form the standby state screen 42 corresponding to the abnormal state, the power saving state, and the normal state, respectively. The combination F defines a car screen, an animal screen, and a person screen as standby state screens 42 corresponding to the abnormal state, the power saving state, and the normal state, respectively. Note that, although the screen is shown with characters in fig. 11 for convenience, the screen actually shows a photograph or a picture, not characters.

In the refrigerator 10 described above, the user can select any one combination from among the plurality of combinations D, E, F shown in fig. 11 by operating the display operation unit 13. For example, the user can select the combination E by touching a button of the combination E displayed on the display operation unit 13. If the combination E is selected, the screen of the animal is selected as the standby state screen 42 in the abnormal state, the screen of the brand name is selected as the standby state screen 42 in the power saving state, and the screen of the landscape is selected as the standby state screen 42 in the normal state.

When executing the standby state screen display process shown in fig. 8, the control section 30 of the refrigerator 10 displays the standby state screen 42 on the display operation section 13 based on the combination selected by the user. When the display operation unit 13 displays the standby state screen 42, the control unit 30 displays the standby state screen 42 included in the combination selected by the user. For example, when the combination E shown in fig. 11 is selected and the first standby state screen 42a corresponding to the abnormal state is displayed in S31 shown in fig. 8, the control unit 30 displays the screen of the animal (see fig. 10 in which reference numeral "42 c" is replaced with "42 a"). When the second standby state screen 42b corresponding to the power saving state is displayed in S33, the control unit 30 displays a screen of the brand name (see fig. 5 (see reference numeral "42 a" replaced with "42 b")). In addition, when the third standby state screen 42c corresponding to the normal state is displayed in S34, the control unit 30 displays a landscape screen (see fig. 9 (see reference numeral "42 b" instead of "42 c")).

The sixth embodiment has been described above. As is apparent from the above description, in the sixth embodiment, the control unit 30 displays the selection screen 60 on the display operation unit 13, which defines an arbitrary combination among the combinations (for example, the combination D, E, F) of the plurality of standby state screens 42 defining the standby state screens 42 corresponding to the plurality of states (for example, the abnormal state, the power saving state, and the normal state) of the refrigerator main body 11. When the display operation unit 13 is operated to select an arbitrary combination (for example, combination E) from among the combinations of the standby state screens 42, the control unit 30 displays, on the display operation unit 13, the standby state screen 42 corresponding to the state of the refrigerator main body 11 among the standby state screens 42 (for example, the animal screen, the brand name screen, and the landscape screen) included in the selected combination (see S31, S33, and S34 of fig. 8). According to this configuration, since the standby state screen 42 selected by the user is displayed on the display operation portion 13, the user of the refrigerator 10 viewing the display operation portion 13 can easily recognize the state of the refrigerator 10.

(other embodiments)

(1) When the display operation unit 13 displays a background color (for example, blue) indicating that the state of the refrigerator main body 11 is a normal state, the control unit 30 may turn off the backlight 19 of the display operation unit 13 after a predetermined time (for example, 2 minutes) has elapsed from the display of the background color. Similarly, when the display operation unit 13 displays a background color (for example, green) indicating that the refrigerator main body 11 is in the power saving state, the control unit 30 may turn off the backlight 19 of the display operation unit 13 after a predetermined time (for example, 2 minutes) has elapsed from the display of the background color. On the other hand, when the background color (for example, red) indicating that the state of the refrigerator main body 11 is abnormal is displayed on the display operation unit 13, the control unit 30 may not turn off the backlight 19 of the display operation unit 13 even after a predetermined time has elapsed. The control unit 30 may continuously turn on the backlight 19 of the display operation unit 13. When the user of the refrigerator 10 performs an operation for turning off the backlight 19 in the display operation portion 13, the control portion 30 may turn off the backlight 19. According to this configuration, since the backlight 19 is not turned off when the state of the refrigerator main body 11 is an abnormal state, the user can easily recognize that it is in the abnormal state.

(2) In the above-described embodiments, the display operation unit 13 is provided in the door 12 of the refrigerating compartment 14 (see fig. 1), but the present invention is not limited to this configuration. In other embodiments, the display operation unit 13 may be provided in a drawer-type door of the freezing compartment 15. The position where the display operation unit 13 is provided is not particularly limited.

(3) In the above embodiments, the refrigerator 10 is described as an example of the home appliance, but the type of the home appliance is not particularly limited. In other embodiments, the household appliance may be a washing machine, a dust collector, an induction cooker, an air conditioner, and the like.

(4) In the third and seventh embodiments, a plurality of combinations a-C or D-F are displayed on one screen, but the present invention is not limited to this configuration, and a plurality of screens may be displayed.

(5) The background color display processing (refer to fig. 6) and the standby state screen display processing (refer to fig. 8) may be executed simultaneously. The control part 30 may change the background color and change the standby state screen 42 according to the state of the refrigerator main body 11.
