Description

Air shielders for freezing and defrosting. {Refrigeration and Defrosting Air Shielders}

The present invention relates to an air shield of a freezer. To be more specific, when the air shield of a freezer circulates cold air, it radiates electric charges into the inner space and continuously stimulates/vibrates water molecules, thereby suppressing cell destruction. This is done to minimize tissue damage during thawing and maintain the state before freezing as much as possible.

In general, meat, fish, shellfish, etc. (hereinafter referred to as products) are stored frozen in the freezer because they spoil easily.

At this time, the freezer has a polygonal case with a door formed to open or close the inner space, while the cold air generated by the heat exchange means circulates inside the inner space to freeze the products provided in the inner space. It is composed.

At this time, products such as meat, fish and shellfish contain a large amount of moisture, so when frozen, the moisture freezes and the volume increases. In particular, the inside and outside of each product freezes at different speeds, damaging the internal structure of the meat product. There was a problem that had to be addressed.

In other words, moisture has the characteristic of increasing its volume in the solid state compared to in the liquid state. In particular, since products containing such moisture are frozen slowly and unevenly from the outside, the inside of each product is absorbed by ice molecules when frozen. This causes tissue damage (cell destruction).

And when thawing, the frozen moisture changes to a liquid state and moisture along with the meat juice gradually escapes through the cracks in the damaged tissue, which not only deteriorates the quality of the meat but also lowers the yield (the overall mass decreases due to the outflow of moisture and juice). There was a problem that led to economic loss.

KR 10-1173641 B1

Therefore, the problem that the present invention aims to solve is to minimize the change in yield (mass) due to the outflow of meat juice during thawing by minimizing the change in yield (mass) due to the outflow of meat juice during freezing, and to minimize the decrease in freshness due to outflow of moisture. It is for this purpose.

For this purpose, the present invention radiates electric charges into the inner space to create an electric field when circulating cold air and freezing it below 0 degrees, so that the electric charges continuously stimulate/vibrate the water molecules, causing the cells inside to be destroyed by the ice molecules. The goal is to suppress it as much as possible.

That is, in the present invention, a door is formed in a polygonal case to open or close the inner space, and the cold air generated by the heat exchange means is circulated into the inner space through the air shield in the case, thereby maintaining the inner space. It is configured to freeze the product, and the air shield is provided with a discharge plate on the flow path along with a circulation means inside the ventilation hole, and the discharge plate is configured to form an electric field in which the inner space is filled with charges by a controller, so that the charges By continuously stimulating/vibrating the water molecules in each product, ice molecules suppress cell destruction while minimizing changes in yield and loss of freshness during thawing.

Therefore, in the present invention, when cold air is circulated and frozen below 0 degrees, the electric charge continuously stimulates/vibrates the water molecules of each product, so when the temperature falls below -5 degrees, the inside and outside freeze together at a similar time ( By minimizing uneven freezing, it is possible to minimize the destruction (damage) of ice molecules to the internal structure of the product.

Therefore, the present invention not only minimizes damage to the internal structure while maintaining the yield change and freshness as much as possible during thawing, but also has the effect of rapid freezing at around -5 degrees. In other words, it can be operated at significantly lower operating costs (electricity costs) than conventional deep freezers.

Therefore, it should be interpreted with meaning and concept consistent with the technical idea of the present invention.

Therefore, since the embodiments described in the specification and the configurations shown in the drawings are only preferred embodiments of the present invention and do not express the entire technical idea of the present invention, these configurations can be replaced at the time of filing. It should be understood that various implementations may be made through equivalents and modifications.

Hereinafter, specific details for carrying out the present invention will be described with reference to the attached drawings.

Figure 1 shows the overall appearance of a freezer equipped with an air shield according to an embodiment of the present invention, Figure 2 shows the appearance of the air shield emitting electric charges, and Figures 3 and 4 show the appearance of water molecules due to electric charges. It shows receiving vibration/stimulation, Figure 5 shows the dispersed discharge plate operating according to the set pattern, Figure 6 shows the configuration of the controller, and Figure 7 shows the appearance of the discharge plate.

As shown, the freezer 1 of the present invention is configured to have a polygonal case 2 with a door 3 formed to open or close the inner space 4, and the case 4 is formed by heat exchange. It is provided with a refrigeration means (5) for generating cold air and an air shielder (10) for circulating the cold air generated by the refrigeration means into the inner space, and the air shielder (10) has a circulation means inside the ventilation hole (11). A discharge plate 60 is provided with (20), and the discharge plate 60 is configured to make the inner space 4 into an electric field filled with electric charges by the controller 30, so that the electric charges are stored in each product ( By continuously stimulating/vibrating the water molecules (7) contained in 6), the ice molecules (8) suppress cell destruction (damaging tissue) while minimizing changes in yield and loss of freshness during thawing. .

At this time, the air shielder 10 protects the water molecules of each product 6 by the electric charge forming the electric field even if the temperature of each product 6 falls below 0 degrees due to the cold air generated by the refrigeration means 5. As (7) receives continuous stimulation and vibrates, uneven freezing of the outside and inside of each product at different speeds is minimized.

In other words, the water molecules of each product (6) are stimulated and vibrate by the electric charge forming the electric field when the temperature drops below 0 degrees, thereby minimizing freezing on the outside and maintaining the boundary value when the temperature drops below -5 degrees. As the water exceeds the limit, the water molecules on the inside and outside are frozen together (minimizing uneven freezing), resulting in rapid freezing.

By minimizing damage to the internal structure of each product by ice molecules, it prevents the juice and moisture of the product from leaking out during thawing, thereby reducing yield and freshness.

At this time, the air shield 10 can be configured in a modularized state with a discharge plate 60 in the inner space 4 to directly turn the inner space 4 into a battlefield.

Preferably, a plurality of vent holes 11 are formed at regular intervals inside the inner space 4, and a flow path and a cold air generation space are formed with a circulation device for circulating air in the vent hole, and the flow path or cold air generation space is formed. A discharge plate is provided so that when the discharge plate is driven, charges are spread evenly inward through each ventilation hole into the inner space to form an electric field.

And this air shielder (10) is connected to the controller (30) to control its operation, and the controller (30) controls the level of moisture contained in each product (8) depending on the type and characteristics of each product (8) accordingly. Constructed to form a battlefield.

That is, the controller 30 forms a control panel 37 on one side of the case that includes buttons for controlling the type of product or the amount of electric charge radiated,

Inside, there is a microcomputer (31) that controls to apply high voltage to the discharge plate according to the type of product set through the control panel, and the primary and secondary coils are magnetically coupled to boost commercial power to a high voltage and apply it to the discharge plate. It is equipped with a transformer (32) that operates.

In addition, a discharge unit 33 is connected to the microcomputer 31 and is provided between the secondary coils of the transformer 32 to selectively apply a high voltage adjusted according to instructions from the microcomputer to the discharge plate.

At this time, the microcomputer 31 is equipped with a door sensor unit 39 and a timer 38 that can detect the opening and closing of the door inside the case so that the battlefield can be stably formed according to the door that opens and closes irregularly. When the microcomputer detects the opening of the door through the door detection sensor, it resets the time counted through the timer, and when the door closes to form a sealed internal space, the timer counts the time that formed the battlefield through the door sensor unit. It is configured to vary the intensity of the voltage applied by the discharge unit to the discharge plate 60 in stages according to the time it takes to turn the sealed inner space into an electric field.

That is, the discharge unit 33 is configured to initially apply a high voltage to turn the inner space into an electric field, and then, if the door is not opened after a certain period of time, receives instructions from the microcomputer 31 to prevent overcharging and uses the discharge plate 60. ) lowers the intensity of the voltage applied to the device in stages (e.g., 9-stage operation after 10 minutes, 8-stage operation after 40 minutes, 7-stage operation after 80 minutes, etc.) to lower operating costs (e.g., electricity bills) while also ensuring safety. to make it run.

In addition, the discharge unit 33 is one of a plurality of lowering units 35 under the direction of the microcomputer 31 according to the type and characteristics of the product 8 or according to the opening and closing time of the irregular door (time for forming an electric field). A switching unit 34 is formed to be selectively connected to any one, and the switching unit includes a plurality of lowering units 35 to lower the output voltage in stages or according to the type of product designated through the menu button.

In addition, the discharge unit 33 may include an oscillator 36 that applies vibration to the discharge plate 60 to spread the discharge evenly along the flow path when controlling the discharge of electric charges by applying a high voltage.

At this time, the oscillator 36 may apply stimulation to the discharge plate through a vibration motor or oscillator circuit depending on the embodiment, but preferably feeds back the voltage output to the transformer toward the primary coil to boost the voltage and automatically generates the voltage through the phase difference. This causes the discharge plate 60 to vibrate and oscillate.

In addition, as shown in FIG. 6, the microcomputer 31 installs a plurality of discharge plates 60 at regular intervals or dispersedly inside the inner space, and then applies one or part of the plurality of discharge plates in a certain pattern ( (e.g., repeating the operation of operating the left discharge plate for 10 minutes and then operating the right discharge plate for 10 minutes), the operation can be controlled to form as uniform an electric field as possible.

In addition, the discharge plate 60 turns the inner space into an electric field as the surrounding air is ionized by corona discharge, and at this time, water molecules contained in foreign substances, etc. are continuously vibrated/stimulated through the electric charge forming the electric field. .

At this time, the discharge plate 60 repeatedly radiates charge when a high voltage is applied, and preferably has a plurality of perforated holes formed on the inside, and the bottom and edge are finished or cased with an insulator to prevent short circuit.

That is, as shown in FIG. 8, the discharge plate forms convex protrusions 62 that protrude upward at regular intervals on the flat metal plate 61, while at the same time forming concave protrusions in the downward direction between adjacent protrusions. It forms part 63. At this time, during drawing with a press, a perforated hole 64 is formed on the inside of the inner part in the upward and downward direction, and the edge of the metal plate is closed with a finishing frame 65 and a current terminal 66 is formed.

At this time, the protrusion 62 and the inner part 63 are simultaneously embossed and punched in a circular cone shape, and the perforated end portion is formed with a sharp edge to improve the straightness and movement distance of the charge radiated by the protrusion. Meanwhile, the charge radiated by the inner part spreads widely to the left and right and has directivity.

Therefore, in the present invention, when each product is frozen below 0 degrees by circulating cold air, the water molecules of each product are stimulated by the electric charge forming an electric field, thereby minimizing uneven cooling of the inside and outside, so that the ice molecules do not cool inside the product. Destruction of tissue can now be suppressed, thereby minimizing changes in yield and loss of freshness during thawing.

The present invention has been described so far with reference to the attached drawings, but these are merely illustrative, and those skilled in the art can easily implement various modifications and equivalent theories. There will be. Therefore, the true technical protection scope of the present invention should be determined by the patent claims.
