Problems solved by technology

Therefore, it takes time to start the rapid cooling operation such as increasing the rotation speed of the compressor or the cooling fan after putting in the stored items.
That is, the time for cooling the storage to the optimum storage temperature becomes longer, so there is a problem that the freshness of the food is lowered.

[0073] Hereinafter, a first embodiment of the present invention will be described.

[0074] figure 1 It is a front view of refrigerator 50 of 1st Embodiment of this invention.

[0075] Such as figure 1 As shown, refrigerator 50 includes refrigerator main body 11 . The main body 11 of the refrigerator is a heat-insulating box made of an outer box mainly made of steel plates, an inner box formed of resin such as ABS, and a heat-insulating material such as polyurethane (urethane) located in a space between the outer box and the inner box. structure, while insulated from the surrounding.

[0076] Refrigerator main body 11 is thermally insulated and partitioned (partitioned) into a plurality of storage rooms (storage rooms). Refrigerating room 12 is provided at the uppermost part, and ice making room 13 and switching room 14 are provided side by side in parallel at the lower part of refrigerating room 12 . Freezer compartment 15 is disposed below ice making compartment 13 an...

Abstract

A refrigerator (50) provided with: a storage compartment for storing storage items, the compartment being partitioned by an insulating wall and an insulating door; a storage volume estimation unit (23) for estimating the storage volume of the storage compartment; and a memory unit (64) for recording the estimation result of the storage volume estimation unit (23). The refrigerator is further provided with a calculation controller (22) for calculating a storage change volume on the basis of the previous estimation result of the storage volume recorded in the memory unit (64) and the estimation result of the storage volume estimation unit, and controlling the output operation of electrical function components. The calculation controller (22) compares a preset threshold and the storage change volume, determines that the storage volume has changed when the storage change volume exceeds the threshold, and controls the output operation of the electrical function components.

Description

technical field [0001] The present invention relates to a refrigerator provided with means for detecting the storage volume of a store room. Background technique [0002] As a cooling method of recent household refrigerators, an indirect cooling method in which a fan circulates cold air in the refrigerator is generally used. Such a conventional refrigerator includes a refrigerator temperature sensor for detecting the temperature of the refrigerator and a freezer temperature sensor for detecting the temperature of the freezer in the refrigerator. In addition, conventional refrigerators perform temperature adjustment control based on the detection results output from these sensors, thereby maintaining the temperature in the refrigerator at an appropriate temperature. [0003] For example, there is a refrigerator provided with a movable cold air discharge device as a refrigerator capable of uniformly maintaining the temperature inside the refrigerator (for example, refer to Pa...
