no. 1 Embodiment approach

[0032] Below, refer to Figure 1 ~ Figure 3 The first embodiment of the present invention will be described.

[0033] figure 2 It is a vertical side view schematically showing the overall configuration of the refrigerator 1 . The heat insulating box 2 of the refrigerator 1 is constituted by filling the heat insulating material 5 formed of, for example, rigid urethane foam or vacuum heat insulating material between the steel plate outer box 3 and the plastic inner box 4, whereby the inside of the box and the The outside of the box is insulated.

[0034] The inside of the heat-insulating box 2 (inside the box) is separated by the heat-insulating partition wall 2a, the lower section is the refrigerating room 6, and the upper section is the freezing room 7. On the front portions of these refrigerator compartments 6 and freezer compartments 7, hinged doors 8 and 9 are provided, respectively.

[0035] On the upper rear wall surface of the refrigerator compartment 6, a refrigera...

no. 2 Embodiment approach

[0078] Refer to the following Figure 4 and Figure 5 A second embodiment of the present invention will be described. In the above-mentioned first embodiment, the refrigerator 1 provided with one cooler was shown, but the refrigerator 31 of this embodiment is comprised including two coolers.

[0079] Figure 4 It is a longitudinal sectional side view of the refrigerator 31. FIG. The heat-insulating box 32 of the refrigerator 31 is constituted by filling, for example, a heat-insulating material 35 formed of hard urethane foam or a vacuum heat-insulating material between a steel plate outer box 33 and a plastic inner box 34, whereby the inside of the box and the box The outside is insulated. The inside of the heat insulating box 32 (the inside of the box) is partitioned by a plurality of heat insulating partition walls 32 a, the uppermost stage is the refrigerator compartment 36 , and the lowermost stage is the freezer compartment 37 .

[0080] Such as Figure 5 As shown, ...

Abstract

A refrigerator can maximumly prevent the time spending and uses a simple structure with restrained cost for properly performing the defrosting of a cooler in an initial defrosting period after a power source is switched on. The refrigerator is provided with a setting unit which sets a defrosting setting time in the initial defrosting period after the power source is switched on to an initial defrosting setting time (J1 or J2) according to a cooler temperature which is detected by a temperature detecting unit when the power source is switched on. So that the defrosting setting time (J1) which is set at a state that the cooler temperature detected by the temperature detecting unit when the power source is switched on is shorter than the initial defrosting setting time (J2) set at a state the cooler temperature is higher than the preset time (T).

Description

technical field [0001] The present invention relates to a refrigerator that performs defrosting of a cooler based on an integrated value of cooling time in a box. Background technique [0002] The operation of the refrigerator is controlled by a control device mainly composed of a microcomputer, and the defrosting operation of the cooler for cooling the inside of the box is also controlled by this control device. [0003] Specifically, the control device integrates the cooling time of the cooler in the box, and when the integrated value reaches a preset defrosting set time, defrosting of the cooler is executed. [0004] In such defrosting control, the controller initializes the integrated value of the cooling time when the integrated value of the cooling time reaches the set time for defrosting, that is, when the cooler is defrosted. [0005] Therefore, the defrosting of the cooler is performed periodically every time the integrated value of the cooling time reaches the se...
