Abstract

The refrigerator provided by the present invention comprehensively judges the operating load state of the refrigerator from the operating state of the compressor, the set temperature of each storage room, etc., and displays the operating load state, thereby reporting the more accurate operating state of the refrigerator to the user. In S1, the load level A is calculated from the set temperature of each storage room. After the load levels are calculated in S1 to S5, the total of the load levels A to E is calculated as the load level α of the refrigerator (S6). When the load level α is 3 or more, it is determined that the operating load state is "large" (S13).

Description

technical field

[0001] The present invention relates to a refrigerator displaying the operating load state. Background technique

[0002] In the past, in refrigerators with variable-speed compressors, the display unit for displaying the temperature inside the refrigerator can display various stages of compressor rotation speeds. When the compressor rotation speed is high, the user can control the door switch. A reduction in power consumption is sought. (For example, refer to Patent Document 1)

[0003] In addition, in a refrigerator having a mechanism for counting the operating time of the compressor within a predetermined time (for example, 24 hours), when the operating time of the compressor exceeds a certain time, a pre-stored image can be displayed on the display to notify the user. To what extent is the compressor operating. (For example, refer to Patent Document 2)

Embodiment Construction

[0030] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0031] figure 1 It is a front view of the refrigerator of this embodiment. Refrigerator 100 has refrigerator compartment 101 on the uppermost stage, and refrigerator compartment 101 has refrigerator compartment door 111 . The refrigerator compartment 101 includes an ice maker compartment 102 with an ice compartment door 112 , a vegetable compartment 103 with a vegetable compartment door 113 , a freezer compartment 104 with a freezer compartment door 114 , and a transfer compartment 105 with a transfer compartment door 115 , respectively. The operation panel 1 is attached to the refrigerator compartment door 111 . In addition, a door switch 23 for detecting the opening and closing of the door is installed in each storage room (refer to the following description). Figure 4 ) and a temperature sensor 24 that detects the temperature in each storage room (refer to the F...
