Description

[Detailed description of the invention] This invention relates to a two-temperature refrigerator that forms a freezer compartment and a refrigerator compartment, and supplies cold air from the freezer compartment to the refrigerator compartment using a refrigerator compartment fan. In addition to stopping the operation of both fans for the refrigerator compartment and reducing outside air intrusion into the freezer compartment, stopping the supply of cold air to the refrigerator compartment and stopping the operation of the refrigerator compartment fan when the refrigerator compartment door is opened. The purpose is to reduce the intrusion of outside air into the refrigerating room and to stop the supply of cold air to the refrigerating room to prevent temperature increases in the freezing and refrigerating rooms due to the intrusion of outside air.

Below, an embodiment of the present invention will be explained with reference to Figs. The freezer compartment 4 and the refrigerator compartment 5 are separated from each other on the left and right, and a partition 6 is installed horizontally in the opening to divide the openings of the freezer compartment and the refrigerator compartment into two compartments, respectively.

7 is an insulated door of the freezer compartment; 8 is an insulated door of the refrigerator compartment;
The openings of the freezer compartment 4 and the refrigerator compartment 5 are pivotally connected to the refrigerator body 1 so as to be openable and closable.

Reference numeral 9 denotes a cooling chamber housing a cooler 10 and a freezer fan 11; 12 a cooler cover having a freezer outlet 13 formed on the upper slope and a freezer suction port 14 formed on the lower slope; The cooling chamber 9 is formed by providing a cooler cover 12 along the back wall of the cross-section thermal wall 2 of the freezing chamber 4.

Reference numeral 15 designates a side channel cover having a U-shape in cross section, and is provided along the side wall surface of the freezer compartment of the partition wall 3, so that the upper and lower parts thereof are opened 16a.

16b is formed.

The cover is attached to the partition wall 3 such that its upper end is higher than the lower end of the freezer compartment discharge port 13 and its lower end is lower than the upper end of the freezer compartment suction port 14.

Reference numerals 17 and 18 denote a refrigerator compartment discharge port and a suction port provided in the partition wall 3 to communicate the freezer compartment 4 and the refrigerator compartment 5. and a refrigerator compartment side opening 17b located above the opening.

18b, respectively, and a freezer compartment side opening 17 of the discharge port.
a is formed at a position facing into the side passage 16, and the freezer compartment side opening 18a of the suction port is formed at approximately the same height as the freezing compartment suction port 14 and at a position lower than the lower end of the side passage cover 15.

Reference numeral 19 designates a refrigerator compartment fan located on the side of the refrigerator compartment side opening 17b of the refrigerator compartment outlet 17, and 20 designates a fan cover.

Reference numeral 21 denotes a suction port cover that covers the refrigerator compartment side opening 18b of the refrigerator compartment suction port 18, and by providing this cover along the refrigerator compartment side wall surface of the partition wall 3, a suction passage 22 having an opening 22a at the bottom of the refrigerator compartment 5 is created. is formed.

Next, cold air circulation in the freezer compartment 4 and refrigerator compartment 5 will be explained with reference to FIGS. 1 and 3.

Incidentally, although cold air circulation is not performed when the button is pressed in the open state of the refrigerator 1 shown in FIG. 1, an arrow is marked for explanation.

The freezer compartment 4 is cooled by forcibly circulating the cold air heat-exchanged by the cooler 10 in the front-rear direction with the freezer fan 11, and the refrigerator compartment 5 is cooled by forcing the cold air flowing through the side passage 16 into the refrigerator compartment fan 19. The interior of the room is led through the refrigerator compartment discharge port 17, forcedly circulated in the lateral direction, and returned to the freezer compartment 4 through the refrigerator compartment suction port 18, thereby being cooled.

FIG. 4 shows the control electric circuit of the present invention, and 23 is a timer T.
26 is a defrosting device such as an electric heater connected in parallel to the power supply through the normally open contact Ta of the timer; , 27 is a door switch for the freezer compartment 4 which is connected in parallel to the power supply via the freezer fan 11, and 28 is a refrigerator compartment fan 19 and a refrigerator thermostat 29 which are connected in parallel to the freezer compartment fan. The door switch 30 of the refrigerator compartment 5 is a temperature compensation heater that is connected in parallel to the refrigerator compartment fan and is energized by switching the refrigerator compartment thermostat 29. The operation is stopped during defrosting and when the door switch 27 is opened, and the refrigerator compartment fan 19 stops operating when the defrosting switch 27, 28 or the refrigerator compartment thermostat 29 is turned off by the chain line. Operation will be stopped when the opening shown in .

The temperature compensation heater 30 is provided on the refrigerator compartment side of the refrigerator compartment discharge port 17 and suction port 18 to prevent overcooling of the refrigerator compartment 5 and blockage of the discharge port and suction port due to frost.

According to the above configuration, the door switch 27 is opened in the freezer compartment 4.
When the door 7 is opened, the operation of the freezer fan 11 is stopped to reduce the intrusion of outside air into the freezer compartment 4, which reduces the temperature inside the freezer compartment 4 and the temperature rise, and also prevents frost from forming on the cooler 10. At the same time, the temperature inside the refrigerator compartment 5 can be reduced by stopping the operation of the refrigerator compartment fan 19 and stopping the supply of cold air introduced into the refrigerator compartment 5 from the freezer compartment 4 through the refrigerator compartment outlet 17. The rise can be prevented.

Moreover, when the door 8 of the refrigerator compartment 5 is opened, the door switch 28 is opened.
By stopping the operation of the refrigerator compartment fan 19 and reducing the intrusion of outside air into the refrigerator compartment 5, it is possible to reduce the rise in temperature and humidity in the refrigerator compartment 5, and also to reduce the temperature and humidity rise in the refrigerator compartment 5. By stopping the supply of cold air led out to the compartment 4, it is possible to prevent the temperature and humidity inside the freezing compartment 4 from increasing.

Furthermore, when the refrigerator compartment thermostat 29 is opened, the operation of the refrigerator compartment fan 19 can be stopped to prevent overcooling in the refrigerator compartment 5.

As mentioned above, the present invention is to form a freezer compartment and a refrigerator compartment on the right and left by arranging a partition wall with a refrigerator compartment discharge port and a refrigerator compartment suction port inside the refrigerator box, and to install a cooler and a refrigerator in the freezer compartment. A thermostat for the freezer that controls the operation of the indoor fan and compressor;
A refrigerator fan and a refrigerator thermostat are installed in the refrigerator compartment, and the freezer fan stops operating by opening the freezer compartment door switch.
It is characterized by being electrically connected to stop operation when either the refrigerator door switch or the refrigerator thermostat is opened, so that when the freezer door is opened, outside air enters the freezer compartment. In addition to reducing cold air intrusion, it is possible to stop the supply of cold air to the refrigerator compartment and prevent the temperature and humidity from rising inside the refrigerator compartment.Also, when the door of the refrigerator compartment is opened, it is possible to reduce the intrusion of outside air into the refrigerator compartment. This prevents the temperature and humidity of the compartment from rising when either the freezer or refrigerator door is opened, such as by stopping the return of cold air to the compartment and preventing the temperature from rising inside the freezer compartment. It is possible to protect stored items.
