Description

Vacuum room device of the refrigerator

The present invention relates to an invention in which the freezer compartment and a part of the refrigerating compartment are maintained in a vacuum state by a pumping operation by a vacuum pump when the temperature inside the refrigerator is cooled below a predetermined temperature.

In general, the cooling device used in the refrigerator is formed by a refrigeration cycle consisting mainly of compression, condensation, expansion, and vaporization of a refrigerant, and an evaporator that absorbs and cools the surrounding heat as the high-pressure freon gas expands and evaporates rapidly. The inside of the freezer compartment and the refrigerating compartment is kept inside so that the food can be cooled or prevented from spoilage and stored for a long time to maintain freshness.

However, even if the inside of the refrigerator is cooled and kept at a low temperature, air is present, so when food is stored for a long time, food stored in the refrigerator is oxidized and decayed by oxygen contained in the air.

In particular, the refrigerating chamber is stored at a low temperature between 0 ° C and 10 ° C without freezing foods to prevent microbial growth and slow down the enzymes, thus preventing corruption. There was no.

Therefore, the foods stored in the refrigerating compartment cannot be stored for a long time because they deteriorate and decay after a certain period of time.For long-term storage, foods that can be stored in the freezing compartment are extremely limited and freshness is reduced. In the end, frozen foods could not be prevented from being oxidized by air.

The present invention has been made in view of the above-described problems, and an object thereof is to provide a vacuum chamber apparatus of a refrigerator that can effectively prevent a closed end that is oxidized or rotted by air even if the food stored in the refrigerator is stored for a long time.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention for achieving the above object is as follows.

As shown in Figures 1 to 3,

In the refrigerator, a freezing compartment 11 and a refrigerating compartment 12 are formed to maintain a low temperature by a cooling device composed of a refrigeration cycle, and the freezing compartment 11 and the refrigerating compartment are opened and closed by a door 13 hinged to the front of the cabinet 10. 12 is a system of opening and closing.

The technical configuration of the refrigerator described above is a known general technical idea. However, the most important feature of the present invention is to enable the freezing chamber 11 to be formed as a vacuum chamber by the vacuum pump 20 connected to the freezing chamber 11 and the pipe 21.

That is, the vacuum pump 20 having the suction pipe 20a and the discharge pipe 20b is mounted under the cabinet 10. Of course, the vacuum pump 20 is such that the air is discharged from the suction pipe (20a) side to the discharge pipe (20b) side by the action of the wing plate supported by the spring to the rotor rotated at high speed by the motor, Oil is injected in order to prevent leakage, but the configuration is known because it is known known technical details are omitted.

The operation of the vacuum pump 20 is controlled by the control unit 40 that receives a signal from the temperature sensor 42 that senses the temperature of the freezing compartment 11, so that the freezing chamber 11 is kept below a predetermined temperature. The system is operated by receiving a signal from the unit 40.

A pipe 21 for sucking air is connected to the suction pipe 20a of the vacuum pump 20, and an upper end of the pipe 21 is connected to the freezing chamber 11 so that the freezing chamber when the vacuum pump 20 is operated. The freezing chamber 11 can form a vacuum chamber by sucking the air of (11) and discharging it through the discharge pipe 20b of the vacuum pump 20.

The freezer compartment 11 is equipped with a damper 41 operated by a solenoid to open and close the room. The solenoid is a system that is electronically controlled by a signal from the control unit 40.

Of course, since the conventional damper 41 mounted in order to circulate and block the cold air introduced from the evaporator may be used in the freezing compartment 11 or the refrigerating chamber 12, a detailed illustration is omitted, and the control unit 40 is input in advance. It is a natural idea that the freezer compartment 11 is blocked by the damper 41 when the vacuum pump 20 is operated by the program.

Of course, considering that excessive pressure is generated by the formation of the vacuum chamber, a spherical body having an air flow path rotates inside the valve body and uses a pressure valve for opening and closing the room, or for removing the primary pressure. It is also possible to install and use separately, the present invention is not necessarily limited to the configuration of the damper 41 described above.

The opening / closing door 13 is equipped with an air intake valve 30 operated by a button 31. As shown in FIG. 2, the suction valve 30 may include a cabinet of a refrigerator in a state in which a sealing body 33 mounted on a support tube 32 is supported by a spring 34 to block an inlet 35. 10) When the button 31 projecting to the outside is pressed, the support pipe 32 and the sealing body 33 formed in the button 31 are retracted, and the inlet 35 is opened so that the external air is supported by the button 31. Air is introduced through the inlet holes 31a and 32a formed in the pipe 32 to release the vacuum state of the freezer compartment 11.

On the other hand, if the support pipe 32 is formed of a metal, the cylindrical coil 36 is installed on the outside thereof to apply power to form a solenoid valve that is electronically controlled, so the intake valve 30 is controlled. Since it is automatically controlled by the signal of the unit 40, it may be used as a primary pressure removing valve, or may operate the suction valve 30 by a separate operation button.

In addition, when the refrigerator compartment 12 is divided and the compartment refrigerator 12a opened and closed by the damper 41 is formed, and the air suction pipe 21 is connected, the compartment refrigerator 12 may be formed as a vacuum chamber. In this case, a three-line valve 22 having three flow paths is installed at the branch point branched from the air intake pipe 21 to the compartment refrigeration chamber 12a to form the freezer compartment 11 and the compartment refrigeration chamber 12a together in a vacuum chamber. Or it may be preferable that the configuration may be selected to form a vacuum chamber of the two.

Of course, in order to select the vacuum state of the refrigerating chamber 12 and the freezing chamber 11, it is a natural idea that a plurality of selection switches 40a are mounted on the control unit 40.

In the present invention as described above, when power is applied to the refrigerator while the food in the freezer compartment 11 and the refrigerating compartment 12 is stored, the cooled air generated by the evaporator is opened in the freezer compartment 11 and the refrigerating compartment 12. The freezing chamber 11 and the refrigerating chamber 12 are cooled and lowered below a predetermined temperature while being circulated through).

Subsequently, when the temperature sensor 42 senses the temperatures of the freezer compartment 11 and the refrigerating compartment 12 and applies a signal to the control unit 40, the operation of the cooling apparatus is stopped by the control of the control unit 40, and the freezer compartment is stopped. The vacuum pump 20 is operated while the damper 41 mounted in the compartment 11 and the compartment refrigerator 12a is closed.

Therefore, the air in the freezing compartment 11 and the compartment refrigerating compartment 12a sealed inside by the damper 41 is sucked through the pipe 21, the vacuum pump 20, and the suction pipe 20a and then the vacuum pump 20. It is discharged to the outside of the refrigerator through the discharge pipe (20b) of the) and the freezing chamber 11 and the compartment refrigeration chamber 12a is formed as a vacuum chamber.

As such, when the freezer compartment 11 and the compartment refrigerating compartment 12a are formed as a vacuum chamber, the problem that the stored foods come into contact with oxygen in the air is fundamentally prevented, and oxidation can be prevented. As a result, the number of operation of the cooling device is reduced, which has the advantage of saving considerable power energy.

Of course, even in a vacuum state, the temperature in the freezer compartment 11 and the compartment refrigerating compartment 12a is increased, so that when the predetermined time passes and the temperature rises above a predetermined temperature, the damper 41 controlled by the control unit 40 automatically opens. Of course, the cooling air generated from the evaporator is supplied to the freezing compartment 11 and the compartment refrigeration chamber 12a to be kept at a low temperature, and the operation of forming the vacuum chamber again by the operation of the vacuum pump 20 is repeated.

On the other hand, when the freezing compartment 11 and the compartment refrigerating chamber 12a is in a vacuum state when the opening and closing door 13 of the refrigerator occurs, the button 31 of the intake valve 30 protruding outside the cabinet 10 of the refrigerator When pressing (), the support tube 32 and the sealing member 33 which are built up in the button 31 are retracted, and the suction port 35 is opened so that the inlet hole formed in the button 31 and the support tube 32 is opened. 31a) is introduced through the 32a and is configured to easily open and close the door while the vacuum state of the freezer compartment 11 is released.

In the present invention as described above, the pipe 21 is provided in the suction pipe 20a of the vacuum pump 20 operated by the control unit 40 receiving the signal of the temperature sensor 42 mounted inside the refrigerator. The pipe 21 is connected to the freezing chamber 11 which is opened and closed by the damper 41 to suck in air, and the opening / closing door 13 has an air suction valve operated by a button 31. By configuring the vacuum chamber apparatus of the refrigerator equipped with 30, the air in the freezer compartment 11 and the compartment refrigerator compartment 12a sealed inside by the damper 41 is provided with a pipe 21 and a vacuum pump 20, After being sucked through the suction pipe 20a and discharged to the outside of the refrigerator through the discharge pipe 20b of the vacuum pump 20, the freezer compartment 11 and the compartment refrigerator 12a are formed as a vacuum chamber, and the freezer compartment 11 and the compartment refrigerator compartment Foods stored in (12a) are completely blocked from oxygen in the air and food is oxidized. Because it prevents the end of the lungs, it prevents the growth of microorganisms and the action of enzymes to prevent decay and maintains the freshness of food even if stored for a long time. The number of operations is significantly reduced, which has the advantage of saving significant power energy.
