Description

Quenching Device for Refrigerator

The present invention relates to a quenching device for a refrigerator.

In general, the refrigerator is configured to store food for a long time using a freezing cycle, which is divided into a refrigerator compartment for storing food that can be stored for a relatively short period of time, and a freezer compartment for storing food for a very long time compared to the refrigerator compartment. .

The refrigerator is made of a heat insulating material such as foamed styrofoam as shown in FIG. 5, and is provided in a case 50 installed in the refrigerator and freezer compartments A and B, and the front side of the refrigerator and freezer compartments A and B. Refrigerators and freezing doors 51 and 52 provided to be opened and closed, a plurality of shelves 53 provided to store articles in the refrigerator compartment A and the freezer compartment B, and a damper on the rear surface of the freezer compartment B. The rear duct 57 is installed between the evaporator 55 and the cooling fan 56 installed with the cover 54 interposed therebetween and the evaporator 55 and the damper cover 54 to form a cold air passage. It consists of).

In addition, the damper cover 54 is formed with a plurality of vent holes 58 so that cold air circulates and moves, and the freezing chamber B is a quenching device for rapidly cooling food that is easily decayed, such as meat. Is installed.

The quenching apparatus includes a discharge hole 59 formed at one side of the damper cover 54, a box 60 formed to shield one side of the freezer compartment B at the discharge hole 59, and the box ( 60 is provided as a storage container 61 is provided so that it can be stored, taken out and inserted meat and the like.

That is, as the cold air blown from the cooling fan 56 is circulated to the discharge hole 59 through the storage container 61, the cold air is driven into the storage container 61, and the storage container ( 61) The meat stored inside is rapidly cooled.

However, as described above, rapid cooling by concentrating the circulating cold air from the evaporator in the storage container causes the problem of low rapid cooling efficiency since the cooling is substantially dependent on the convection of the cold air.

In addition, since the quenching efficiency is low, the user waits for a very long time while the meat is placed in the storage container, and the meat is frozen when the meat is forgotten to be inserted into the storage container.

Accordingly, an object of the present invention is to provide a quenching apparatus for a refrigerator that can facilitate the storage of meat by improving the rapid cooling efficiency of the refrigerator.

In order to achieve the above object, the present invention provides a refrigerator quenching apparatus including a box provided to form a space inside the freezer compartment, and a storage container formed in a box shape to receive and withdraw the box and circulate cold air. An auxiliary vent formed on the back of one box, an intermittent blocking means installed in the freezer compartment to intermittently block the direction of cold air flowing into the vent, a temperature sensor installed in the box to measure the temperature inside the box, Characterized in that composed of a microcomputer connected to the temperature sensor.

1, 2 and 3 are exploded perspective views and assembling cross-sectional views showing a refrigerator perspective view and an intermittent blocking means showing the quenching apparatus for a refrigerator according to the present invention, wherein the auxiliary vent hole 1 formed on the back of the box 60 is shown. And intermittent blocking means installed in the freezer compartment (B) to intermittently block the direction of the cold air flowing into the vent (58), and installed in the box 60 to measure the temperature inside the box 60 It consists of the installed temperature sensor 2 and the microcomputer 3 connected to the above-mentioned temperature sensor 2.

In particular, the micom (3) is provided with an alarm such as a buzzer (4), such that when the temperature inside the box 60 is below a certain level, an alarm is issued.

The intermittent blocking means is installed as a hinge 5 on the side of the box 60 so as to be rotatable, and one end is inserted into the rectangular first operating hole 6 formed in the damper cover 54. The coupling hole 8 is formed to be coupled to the bar 7 inserted into the first operation hole 6 in a state having a predetermined clearance, and the corresponding hole 9 is intermittently coincided with the ventilation hole 58. And a guide 11 formed around the vent hole 58 of the damper cover 54 so that the blocking plate 10 slides from the rear surface of the damper cover 54. have.

In particular, when the coupling hole 8 of the bar 7 and the blocking plate 10 is coupled to the end of the bar 7 so as to generate elasticity to smoothly reciprocate the blocking plate 10 due to rotation. An elastic groove 12 is formed, and the knob 14 is installed to be inserted into the second operation hole 13 formed in the box 60 and coupled with the other end of the bar 7 to operate it. It is.

In addition, the cover 15 is attached to the side of the box 60 so that the bar 7 and the temperature sensor 2 are not visible from the outside.

An air guide 16 is provided on the rear surface of the damper cover 54 so as to collect the cold air toward the auxiliary vent hole 1 side.

That is, when the user operates the intermittent blocking means, the blocking plate 10 blocks or opens the air vent 58, thereby changing the air flow rate of the cold air, thereby allowing the cold air to flow into the auxiliary air vent 1. When explaining the operation and effect of the present invention as described above that the rapid cooling by increasing or decreasing the amount of the user to open the freezing door 52 in order to rapidly cool the meat and the like to take out the storage container 61.

After taking out the storage container 61, meat is stored in the storage container 61, the storage container 61 is inserted into the box 60, and the knob 14 located at the front of the box 60. Will slide to the quench position.

When the knob 14 is moved in the quench mode, the bar 7 connected to the knob 14 rotates around the hinge 2, and the blocking plate connected thereto is rotated by the rotation of the bar 7. 10) while blocking the vent (58).

That is, the blocking plate 10 is moved by the bar during the quenching mode operation in the state where the corresponding hole 9 of the blocking plate 10 and the ventilation hole 58 of the damper cover 54 coincide with each other. The ball 9 and the ventilation hole 58 is out of alignment and is out of position so that the ventilation hole 58 is blocked.

When the air vent 58 is blocked by the blocking plate 10, the cold air blown from the cooling fan 56 is concentrated in the auxiliary air vent 1.

In particular, by the air guide 16 formed in the damper cover 54, the cool air is collected very smoothly in the direction of the auxiliary vent hole (1) to increase the discharge efficiency of the cold air.

As described above, when cold air is concentrated and supplied to the storage container 61 through the auxiliary vent hole 1, the temperatures of the storage container 61 and the box 60 are drastically lowered, which causes rapid cooling of meat and the like. This is done smoothly.

For example, in the conventional quenching method, when quenching meat, which is 30 ° C., is used for about 140 minutes to lower it to about 15 ° C., in the present invention, it takes about 50 minutes, so that about 2/3 It is effective in reducing the quench time.

Of course, the cold air supplied to the storage container 61 is again dispersed throughout the freezer compartment (B) through this. At this time, when the temperature inside the storage container 61 and the box 60 is below a certain level, for example, an optimum quenching temperature, the temperature sensor 2 senses it and delivers it to the microcomputer 3. When the temperature signal is input to the microcomputer 3, the buzzer 4 is raised so that the user can listen to the sound of the buzzer 4 and draw meat without worrying about quenching.

As described above, the present invention blocks the cold air discharged to the air vent during the quenching with a blocking plate and reduces the quenching time by supplying more cold air to the storage container through the auxiliary air vent, and at the end of the quenching, the buzzer sounds. There is an advantage that can increase the convenience of the user.
