Problems solved by technology

Therefore, when a compressor with reverse phase control is used, if the defrosting is performed based on the cumulative value of the compressor's operating hours, the frequency of defrosting will increase.
[0011] In addition, in the refrigerating device using the compressor with reverse phase control, since the output of the compressor fluctuates, it is difficult to have a proportional relationship between the cumulative value of the operating time of the compressor and the frosting amount of the evaporator. When defrosting control is performed on the integrated value of operating hours, there is a possibility that power is wasted because defrosting is often performed even though the amount of frosting is small.
[0012] Moreover, although there are also refrigerators that perform defrosting control in consideration of the number of times of door opening and closing or the cumulative value of opening time in addition to the movable time of the compressor in the defrosting control of the evaporator (Patent Document 1, Non-Patent Document 1, etc. ), but it is difficult to add the influence of storage rooms with temperature differences, and sometimes it is difficult to optimize the timing of defrosting

no. 1 approach

[0034] Embodiments of the present invention will be described below with reference to the drawings. figure 1 It is a side sectional view of an example of the refrigerator of this invention. Refrigerator A has a heat insulating box 1 filled with a foam heat insulating material. A refrigerating chamber 3 is arranged on the top of the heat-insulating box body 1 . Below the refrigerator compartment 3, a freezer compartment 4 is provided via a partition 101 filled with a heat insulating material. Below the freezer compartment 4, a vegetable compartment 5 is provided via a partition plate 102 filled with a heat insulating material. In addition, it is not necessary to follow the order of the refrigerator compartment, the freezer compartment, and the vegetable compartment, and can be changed according to the frequency of use, the amount of storage items, and the like. In addition, a storage room for storing storage items at a temperature other than these storage rooms may be provid...

no. 2 approach

[0100] Another example of the cooling room of this invention is demonstrated. In this embodiment, the structure of the refrigerator A is the same as that of the first embodiment, and the same reference numerals are attached to the same parts, and the detailed description of the same parts will be omitted.

[0101] In the refrigerator A, the environmental conditions are determined assuming an installation location, and the first coefficient K1, the second coefficient K2, the third coefficient K3, and the fourth coefficient K4 are obtained from the results when the refrigerator A operates under the environmental conditions. On the other hand, there may be differences between the assumed environmental conditions and the actual environmental conditions of the installation location (for example, the humidity is higher than expected). At this time, the amount of frost adhering to the evaporator 12 due to the operation of the refrigerator A (the actual amount of frost) may differ fro...

no. 3 approach

[0119] Another example of the refrigerator of the present invention will be described with reference to the drawings. Figure 9 It is a side sectional view of another example of the refrigerator of the present invention, Figure 10 yes means Figure 9 A block diagram of the structure of the refrigerator is shown. Figure 9 The illustrated refrigerator B has the same structure as the refrigerator A of the second embodiment except that the condensation prevention heater 17 is provided. Therefore, the same code|symbol is attached|subjected to the part of refrigerator B substantially the same as refrigerator A, and the detailed description of the same part is abbreviate|omitted.

[0120] Such as Figure 9As shown, in the refrigerator B, a condensation prevention heater 17 is embedded in the front surface portion of the partition 101 that partitions the refrigerator compartment 3 and the freezer compartment 4 . Although the partition plate 101 has a structure including a heat i...

Abstract

In order to optimize the timing for defrosting by adding the impact of storage compartments with a temperature differential, a refrigerator (A) comprises a control unit (2) that: acquires at least information about the opening / closing of a door (41) of a first storage compartment (41), the opening / closing of a damper (15), and the length of time that a compressor (11) is driven; calculates, on the basis of the acquired information, the anticipated amount of frost for an evaporator (12); and issues instructions for performing defrost operation to a defrost unit (16) when the amount of frost anticipated exceeds a threshold value.

Description

technical field [0001] The invention relates to a refrigerator for storing articles at a low temperature. Background technique [0002] A refrigerator includes a storage room (a freezer room, a refrigerator room, etc.) in which food and the like are stored at a low temperature formed by an insulating space surrounded by a cabinet and a door, and a cooling device that cools the inside of the storage room. In the cooling device used in general refrigerators, the evaporator is connected to the compressor that operates the refrigeration cycle. Cool air generated by exchanging heat with the evaporator is sent into the storage room by driving the fan to cool the storage room. [0003] The evaporator condenses and freezes moisture contained in the air, and deposits (frosts) as frost. If the frost adheres to the evaporator, the area through which air passes is narrowed, so that the heat exchange efficiency is reduced, that is, the cooling capacity of the refrigerator is reduced. ...
