Problems solved by technology

[0006] However, the above-mentioned refrigerator only reports the operating state of the compressor to the user, but in fact, the operating state of the refrigerator cannot be determined only based on the operating state of the compressor, and may vary depending on the set temperature of each storage room or the temperature of the outside air. , so there is a problem that it is difficult to grasp the comprehensive operating state

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...

Abstract

The invention provides a refrigerator in which an operation load state of the refrigerator is comprehensively determined on the basis of an operation state of a compressor, a set temperature of each of storage compartments and the like, and more accurate operation state of the refrigerator is notified to a user by displaying it. At S1, a load level A is calculated on the basis of a set temperatureof each of storage compartments. After the load level is calculated at S1 to S5, the total of the load levels A to E is calculated as a load level a of alpha of the refrigerator (S6). If the load level alpha is not less than 3, the operation load state is determined to be ''high'' (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) [0004] [Patent Document 1] WO2005 / 026632 Publication (page 13, Figure 4 ) [0005] [Patent Docume...
