A preferred example of the length in the vertical direction in which a plurality of the above-mentioned specific items can be stored may be 2.3 to 3 times the width in the left and right directions, and the most preferred example may be 2.4 to 3 times the width in the left and right directions.

On the other hand, even if the length in the vertical direction of the refrigerator is longer than the width in the horizontal direction, if the length of the first storage chamber W, for example, the first storage chamber W is substantially short, the first storage chamber W may be stored. The number of specific items may not be large. In the refrigerator, it is preferable that the length of the first storage chamber W in the vertical direction is longer than the length of the second storage chamber C in order to store as many specific items as possible. For example, the length of the first storage chamber W in the vertical direction may be 1.1 to 1.5 times the length of the second storage chamber C in the vertical direction.

In order to control the temperature of the storage room W, the refrigerator may be provided with cooling means and heating means that can be independently controlled.

In the refrigerator, cooling means and heating means may be provided to control the temperature of at least one of the storage room, the constant temperature room, and the priority storage room.

The refrigerator may be controlled in a plurality of modes to control the temperature of the storage room W, and the plurality of modes include a cooling mode E in which the storage room W is cooled by cooling means, and a storage room W is heated by heating means. It may include a heating mode (H) and a standby mode (D) for maintaining the current state without cooling or heating the storage chamber (W).

The refrigerator may include a temperature sensor that senses the temperature of the storage room W, and may perform a cooling mode (E), a heating mode (H), and a standby mode (D) according to the storage room temperature sensed by the temperature sensor. have.

In the cooling mode E, the storage chamber W is not limited to being continuously cooled by the cooling means, but the storage chamber W is cooled by the cooling means as a whole, but the storage chamber W is temporarily not cooled by the cooling means. It may be included, the storage chamber (W) is cooled by the cooling means as a whole, it may also include the case where the storage chamber is temporarily heated by the heating means. The cooling mode (E) may include a case in which the time during which the storage chamber is cooled by the cooling means is longer than the time during which the storage chamber W is not cooled by the cooling means.

The heating mode (H) is not limited to the storage chamber W being continuously heated by the heating means, and the storage chamber W is heated by the heating means as a whole, but the storage chamber W is temporarily heated by the heating means. If not, the storage chamber W may be heated by the heating means as a whole, but may also include the case where the storage chamber W is temporarily cooled by the cooling means. The heating mode H may include a case in which the time during which the storage chamber W is heated by the heating means is longer than the time during which the storage chamber W is not heated by the heating means.

The temperature of the storage room W, which has been temperature-controlled in the cooling mode E, is sometimes lowered below the target temperature lower limit for a long period of time while falling below the target temperature lower limit value and maintained below the target temperature lower limit value.

In this case, the refrigerator may start the heating mode (H) so that the storage chamber (W) is not supercooled when the storage chamber temperature reaches the lower limit temperature, and the heating means can be turned on. The lower limit temperature may be a temperature set lower than the target temperature lower limit value.

On the other hand, the refrigerator may initiate a heating mode (H) so that the storage chamber temperature is maintained at a low state for a long time when the storage chamber temperature is maintained between the target temperature lower limit value and the lower limit temperature.

The heating mode H may be started when the storage chamber temperature is a lower limit temperature, and the lower limit temperature may be a heating mode start temperature.

An example of the standby mode (D) may be a mode in which the storage room temperature is maintained between the target temperature lower limit value and the lower limit temperature, and the refrigerator does not immediately switch to the heating mode (H) in the middle of the cooling mode (E), and the cooling mode ( E) and the standby mode (D) and the heating mode (H) can be controlled in this order.

On the other hand, the temperature of the storage room W, which has been temperature-controlled in the heating mode H, may not be lowered below the target temperature upper limit value for a long time in a state where it has risen above the target temperature upper limit value and may maintain the target temperature upper limit value.

In this case, the refrigerator may start the cooling mode (E) so that the storage chamber (W) does not overheat when the storage chamber temperature reaches the upper limit temperature, and can turn on the cooling means. The upper limit temperature may be a temperature set higher than a target temperature upper limit value.

On the other hand, the refrigerator may initiate the cooling mode (E) so that the storage room temperature does not maintain a high state for a long time when the storage room temperature maintains a set time between the target temperature upper limit value and the upper limit temperature.

The cooling mode (E) may be initiated if the storage chamber temperature is an upper limit temperature, and the upper limit temperature may be a cooling mode start temperature.

Another example of the standby mode (D) may be a mode in which the storage room temperature is maintained between the target temperature upper limit value and the upper limit temperature, and the refrigerator does not immediately switch to the cooling mode (E) in the middle of the heating mode (H), and the heating mode It can be controlled in the order of (H), standby mode (D) and cooling mode (E).

For example, the cooling mode (E) may be a mode in which the refrigerant passes through the evaporator and the air in the storage chamber (W) is cooled by the evaporator and then flows into the storage chamber (W). In the cooling mode (E), the compressor may be turned on and off according to the temperature of the storage room (W). In the cooling mode (E), the compressor may be turned on and off to maintain the storage room temperature between the target temperature lower limit value and the target temperature lower limit value. Specifically, the compressor may be turned on when the storage chamber temperature reaches the upper limit of the target temperature, and may be turned off when the storage chamber temperature reaches the lower limit of the target temperature.
