The present invention relates to a refrigerator. More particularly, the present invention relates to a refrigerator so that foods such as vegetables can be stored more freshly by being provided with a real taste chamber that implements independent temperature.

In general, the refrigerator is a device for the purpose of low temperature storage of food is to maintain a variety of food fresh for a long time by using the heat exchanged air from the evaporator of the refrigeration cycle.

Such refrigerators are classified into a freezer compartment and a refrigerating compartment having different temperature ranges, and in particular, the utilization of taste cold compartments that can be independently implemented in the refrigerator compartment can be independently implemented.

The conventional refrigerator includes a refrigerator compartment; An evaporator provided in a rear region of the refrigerating compartment; A first cold air passage for supplying cold air generated from the evaporator into the refrigerating chamber; A real taste chamber provided adjacent to the refrigerator compartment; A second cold air passage branched from the first cold air passage to communicate with the real taste chamber; It is configured to include an electric damper installed on the first cold air flow path. In such a refrigerator, when the electric damper is opened, cold air generated by the evaporator is supplied to the inside of the refrigerating chamber through the first cold air passage, and when the electric damper is closed (when the real taste chamber is operated), the cold air generated by the evaporator is supplied to the electric damper. The flow direction is changed by the second cold air flow path has a structure that is supplied to the inside of the taste chamber. A refrigerator having a similar structure is disclosed in Korean Utility Application No. 20-1997-0035106.

However, when the refrigerator having the structure as described above is intended to supply cold air to the real taste chamber, since the electric damper is kept closed, the dew condensation phenomenon due to the temperature difference frequently occurs because the cold air passing through the first cold air passage hits the electric damper. There is a problem that occurs.

To solve this problem, a heater is installed around the surface of the electric damper.However, in the case of installing the heater, the power consumption of the refrigerator is relatively increased due to the constant power supply of the heater, and the product cost of the refrigerator is increased. Cause.

The present invention has been made in order to solve the above problems, and relates to a refrigerator capable of easily and efficiently supplying the cold air into the taste chamber.

In order to achieve the above object, the present invention, the refrigerator compartment; An evaporator provided in a rear region of the refrigerating compartment; A first cold air passage for supplying cold air generated from the evaporator into the refrigerating chamber; A real taste chamber provided adjacent to the refrigerating chamber; A second cold air passage branched from the first cold air passage to communicate with the real taste chamber; It is characterized in that it comprises a suction fan provided on the second cold air flow path, forcibly suctioning cold air generated from the evaporator and passing through the first cold air flow path into the taste chamber.

The second cold air passage may have a U shape so as to minimize the introduction of cold air supplied into the refrigerating chamber through the first cold air passage when the suction fan is turned off.

It may further include a check valve provided on the second cold air flow path to block the inflow of cold air.

An end portion of the second cold air passage extends to the inside of the real taste chamber, and a plurality of cold air supply ports are formed at an end of the second cold air passage extending into the real taste chamber.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

As shown in Figures 1 to 3, the refrigerator according to the present invention comprises a refrigerator compartment 20; An evaporator 30 provided in a rear region of the refrigerating chamber 20; A first cold air flow passage 40 for supplying cold air generated from the evaporator 30 into the refrigerating chamber 20; A real taste chamber 50 provided adjacent to the refrigerating chamber 20; A second cold air passage 60 branched from the first cold air passage 40 to communicate with the real taste chamber 50; It is provided on the second cold air flow path 60, and comprises a suction fan 70 for forcibly sucking the cold air generated from the evaporator 30 and passing through the first cold air flow path 40 into the taste chamber 50. do.

The refrigerating chamber 20 is provided with a plurality of cold air discharging openings 22 through which cold air is discharged, and a door 90 is provided on the opened front surface of the refrigerating chamber 20.

As the evaporator 30 evaporates the refrigerant at low temperature and low pressure, the air circulated in the refrigerating chamber 20, which is relatively high temperature, exchanges heat, thereby lowering the temperature of the inside of the refrigerator.

The first cold air passage 40 is formed to communicate with the inside of the refrigerating chamber 20, the structure can be changed in various ways.

The second cold air flow path 60 is the first by the operation of the blowing fan 76 when the suction fan 70 is turned off, that is, when the suction pan 70 stops operating because the taste chamber 50 satisfies a predetermined temperature. It is preferable to have a U shape so that the cold air supplied to the refrigerating chamber 20 through the cold air flow passage 40 flows backward to minimize the inflow into the real taste chamber 50.

The shape of the second cold air flow path 60 may be variously changed within a range capable of minimizing reverse flow of cold air.

In addition, on the second cold air flow path 60, a check valve 80 may be provided which can fundamentally block the inflow of cold air as necessary. The reason why the additional check valve 80 is additionally installed is due to the shape characteristic of the second cold air flow path 60, which almost blocks inflow of cold air into the sesame flavor room 50, but may be partially introduced. To prepare for. Cold air flow control means such as the check valve 80 may be selectively applied to a variety of known forms.

An end portion of the second cold air passage 60 extends to the inside of the real taste chamber 50, and a plurality of cold air is supplied to the end of the second cold air passage 60 extending into the real taste chamber 50 so as to distribute and supply cold air. The supply port 62 is formed.

Charm chamber 50 is provided with a temperature sensor (not shown) that can sense the internal temperature. The temperature sensor detects the temperature inside the real chamber 52 in real time and transmits it to a controller (not shown), and the controller controls the operation of the suction fan 70 by temperature information transmitted from the temperature sensor.

The suction fan 70 may optionally use a known type, and is mainly operated during the cold air supply process to the refrigerating chamber 20. On the other hand, since the suction fan 70 does not need a large amount of cold air to satisfy the specific temperature range of the real taste chamber 50, the suction fan 70 operates in a state where the operation of the blower fan 76 is stopped to exist around the evaporator 30. It can be used by inhaling cold air.

Looking at the operation process of the true taste chamber of the refrigerator described above is as follows.

First, the cold air generated from the evaporator 30 is blown by the blower fan 76, and the cold air thus blown is guided through the first cold air passage 40 and supplied into the refrigerating chamber 20.

When the suction fan 70 is operated in this process, a portion of the cold air supplied into the refrigerating compartment 20 through the first cold air passage 40 is forced into the sesame chamber 50 through the second cold air passage 60. Is inhaled. At this time, the suction fan 70 is automatically operated by the temperature sensor inside the taste chamber 50, or by the user's function selection.

When the taste chamber 50 reaches a specific temperature range due to cold air forcedly sucked through the second cold air flow path 60, a temperature sensor detects this and the operation of the suction fan 70 stops and at the same time check valve 80. ) Blocks the flow of cold air supplied into the sesame flavor chamber 50 through the second cold air passage 60.

When the internal temperature of the real taste chamber 50 is out of a specific temperature band, the suction fan 70 is reactivated to supply cold air to the real taste chamber 50 until the specific temperature range is reached.

As described above, according to the present invention, various problems caused by the electric damper can be solved by removing the existing electric damper. That is, the power consumption due to the installation of the electric damper and heater can be reduced, as well as the dew condensation can be prevented, and the economic cost can be reduced.
