Problems solved by technology
Therefore, there is a problem that, by the forced cooling mode, the cooked food cannot be lowered to a desired temperature, and the cooking time cannot be sufficiently shortened due to insufficient cooling.
In addition, there is a problem that cooking food is overcooled in the forced cooling mode and cannot be cooked satisfactorily for the user.

Embodiment Construction
[0062] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 , figure 2 It is a front view and a right side view of the refrigerator which shows an embodiment. In the refrigerator 1, a refrigerating compartment 2 is arranged on the upper level, and a temperature switching compartment 3 and an ice making compartment 4 are arranged on the middle level. A vegetable compartment 5 and a freezing compartment 6 are arranged on the lower level of the refrigerator 1.
[0063] The refrigerating compartment 2 has a side-by-side door, and refrigerates and preserves stored items. The temperature switching room 3 is arranged on the left side of the middle floor, and the room temperature can be switched by the user. The ice making chamber 4 is arranged on the right side of the middle floor to make ice. The vegetable compartment 5 is installed on the left side of the lower floor, and maintains a temperature suitable for storing vegetables (...

A refrigerator having a first storage chamber (2) and a second storage chamber (3) that are separated in a thermally insulated manner and having parallelly arranged cold air circuits; a first damper (13) for opening and closing a connection between a cooler (17) and the inflow side of the second storage chamber (3); a second damper (20) for opening and closing a connection between the cooler (17) and the outflow side of the second storage chamber (3) and guiding cold air to the inflow side of the second storage chamber (3); a blower (14) for circulating cold air in the temperature switching chamber (3) when the first and second dampers (13, 20) are closed; and temperature sensors (24, 16) arranged at the upper and lower parts of the second storage chamber (3). The refrigerator has a coarse heat removal mode where rapid cooling operation and temperature detection operation are repeated. In the rapid cooling operation, the blower (14) is driven, with the first damper (13) and the second damper (20) constantly opened, to cool the second storage chamber (3). In the temperature detection operation, the first storage chamber (2) is cooled with a connection between the cooler (17) and the first storage chamber (2) opened, and the temperature in the second storage chamber (3) is detected by the temperature sensors (24, 16) when a predetermined time has passed after the first and second dampers (13, 20) are closed and the blower (14) is stopped. When temperatures detected by the temperature sensors (24, 16) in the temperature detection operation are less than a predetermined temperature difference, the coarse heat removal mode is finished.
Description
Technical field [0001] The present invention relates to a refrigerator with first and second storage compartments, wherein the first and second storage compartments are insulated by heat insulation and cold air paths are arranged side by side. Background technique [0002] Patent Document 1 discloses a conventional refrigerator. The refrigerator has a temperature switching chamber that switches the indoor temperature in a desired temperature zone such as freezing, refrigeration, micro-freezing, and cooling according to the user's purpose. The temperature switching chamber is insulated from the freezing chamber, and the cold air flow path connected to the cooler that generates cold air is side by side with the freezing chamber. The cold air generated by the cooler by the driving of the compressor is output to the temperature switching chamber and the freezing chamber by the operation of the blower. Thereby, the temperature switching chamber and the freezing chamber are cooled. [...
