Problems solved by technology

[0012] However, in the above-mentioned conventional structure, when the switching damper is opened when the heater is energized, the heat of the heater may flow to other storage rooms through the damper and become a heat load, causing the power consumption of the refrigerator to increase. question
[0013] In addition, since the heater only heats the bottom wall and heats the switching chamber by natural convection, there is a problem that only the bottom is overheated and the center temperature is difficult to rise to the target temperature.

Embodiment approach 1

[0028] figure 1 It is a longitudinal sectional view of the refrigerator in Embodiment 1 of this invention. figure 2 It is a flowchart showing the operation of the refrigerator according to Embodiment 1 of the present invention.

[0029] exist figure 1 Among them, the refrigerator 13 includes a cooling system 4 composed of a compressor 2 , a condenser, a decompression unit, and an evaporator 3 . In addition, the refrigerator 13 includes a refrigerator room 5, a first switching room 14, a second switching room 15, and a third switching room 16 (hereinafter, the first switching room 14, the second switching room 15, and the third switching room 16 are sometimes collectively referred to as In order to switch between the storage compartments (14, 15, 16), openable and closable doors 5a, 14a, 15a, 16a are arranged at the front openings of the respective compartments.

[0030] The evaporator 3 is located behind the second switching chamber 15 and accommodated in the cooling cha...

Embodiment approach 2

[0047] Next, a refrigerator according to Embodiment 2 of the present invention will be described.

[0048] image 3 It is a flowchart showing the operation of the refrigerator according to Embodiment 2 of the present invention.

[0049] based on image 3 The flow chart of FIG. 2 illustrates the operation when the set temperature of the storage compartments 14, 15, and 16 is switched to a temperature higher than the temperature at that time.

[0050] Here, in order to simplify the description, it is only limited to the description of the switching control of the first switching room 14, but in any switching storage room of the first switching room 14, the second switching room 15 and the third switching room 16, the same method can be used. Actions have the same effect.

[0051] When the set temperature of the first switching chamber 14 is switched to a temperature higher than the moment (at image 3 During the temperature (S11, S12) that is recorded as the current temperat...

Abstract

Provided is a refrigerator wherein when the set temperature of a switchable storage room is switched from the low-temperature side to the high-temperature side, heat generated by a heater is blocked by a damper, and other storage rooms are not heated, thereby making it possible to suppress an increase in power consumption. A refrigerator (13) is provided with a plurality of switchable storage rooms (14, 15, 16) and configured such that when the set temperature of the switchable storage room (14) is switched from the low temperature side to the high temperature side, a damper (20) for the switchable storage room (14) is closed, and that a heating part (23) within the switchable storage room (14) is operated.

Description

technical field [0001] The present invention relates to a refrigerator capable of switching the temperature of at least one storage compartment from a freezing temperature range to a refrigeration temperature range. Background technique [0002] In the prior art, the refrigerator is set to a predetermined temperature range for each storage room, the temperature of the freezer can only be adjusted within the range of the freezing temperature range, and the temperature of the refrigerator room can only be adjusted within the range of the refrigeration temperature range. . [0003] However, in recent years, due to the diversification of lifestyles, etc., the food materials purchased by users have also diversified, and the need to switch the temperature range of the storage room and change the storage capacity of the desired temperature range in the predetermined temperature range has also increased. . [0004] Therefore, a refrigerator capable of switching the temperature ran...
