Description

Structure for Decreasing Temperature Difference in Storeroom of Kim-Chi Storage}

The present invention relates to a structure of improving the temperature deviation in the kimchi storage compartment, and more particularly, to provide a forced air generator on the inner circumferential surface of the upper opening door to evenly distribute cold air to the entire area of the kimchi storage compartment temperature variation inside the storage compartment By minimizing the temperature, it is related to the structure of improving the temperature deviation in the storage room of the kimchi storage to maintain the freshness of the food and to allow long-term storage.

In general, kimchi storage is used to maintain the proper ripening state of kimchi for a long time. Initially, the kimchi is matured by using a heating device, and then the temperature is maintained at an appropriate level using a cooling device, thereby maintaining the taste and freshness of kimchi. It is a home appliance to be stored for a long time.

Such kimchi storage generally has a main body in which a storage chamber and a machine chamber are formed along a height direction, and a door provided at an upper portion of the main body.

In the storage chamber, a plurality of storage containers for storing kimchi and the like are accommodated, and an evaporator is provided which surrounds the storage chamber and consists of a refrigerant pipe for supplying cold air. A compressor, a condenser, and a cooling fan are provided in the machine chamber.

Kimchi storage having such a configuration is to open the door to accommodate the storage container storing the kimchi, etc. in the storage chamber, and when the refrigerant is directed to the condenser and the evaporator by the operation of the compressor, the evaporator evaporates the condensed refrigerant in the surroundings By using the latent heat to generate cold air into the storage compartment, the inside of the storage compartment is cooled to a predetermined temperature, and thus the kimchi stored in the storage vessel can maintain its freshness for a long time.

However, in the case of conventional kimchi storage, if the door is not sealed due to long-term use of the kimchi storage, or if the door is frequently opened or closed, the temperature inside the storage room is severely changed, making it difficult to maintain the freshness of the kimchi. Because of the temperature difference between the top and bottom, the storage period of the kimchi located on the upper side had a problem.

For a more detailed description thereof will be described with reference to the drawings of the conventional general kimchi storage as shown in FIG.

As shown in FIG. 1, the conventional kimchi storage chamber includes a main body 11, a storage chamber 12 configured inside the main body 11, and a machine room 14 having a cooling device under the storage chamber 12. ) And a door 13 covering the storage compartment 12 with an upper end of the main body 11.

In the conventional kimchi storage, there is no device for circulation of cold air in the storage compartment 12, so the cold air is circulated by natural convection in the storage compartment 12, so the cold air stagnates below the storage compartment 12 As the lower part maintains a low temperature, and the upper part of the storage compartment 12 maintains a higher temperature, a temperature deviation occurs between the upper part and the lower part of the storage compartment.

In addition, the door 13 is open in the upward direction, and when the door 13 is frequently opened and closed, the intrusion of external air becomes easy, and when the door 13 is assembled, it is impossible to guarantee perfect sealing property, so the storage compartment 12 ) The upper part was affected by the outside air and had a problem that the temperature of the upper part could not be prevented from being slightly higher than the lower part.

When the temperature inside the storage compartment 12 is increased in this way, it takes a lot of time to compensate for this, and since the cold air circulation is not actively performed in the storage compartment 12, it is difficult to completely compensate for the temperature deviation between the upper and lower sides, The temperature at the top stays high for a long time, reducing the freshness of the food on top and making long-term storage difficult.

As described above, in the conventional kimchi storage chamber, since the cold air circulation is performed only by natural convection, the cold air circulation is not active, and thus an up and down temperature deviation occurs in the storage compartment 12, and a perfect seal is formed at the part of the door 13. Since it is not supported, the internal temperature of the storage compartment 12 is increased due to heat transfer of air.

Therefore, as described above, the reason why the temperature variation is large in the upper and lower portions of the storage chamber 12 of the kimchi storage room is that the cold air is not evenly circulated in the storage chamber 12 and external air invades the door 13. Because of the factors, in order to solve this it is necessary to force the convection of the air in the storage compartment 12, it is necessary to continuously supply evenly to all areas inside the storage compartment (12).

The present invention has been made based on the necessity for improving the temperature deviation in the storage compartment as described above, an object of the present invention is to compose a forced air generating device inside the storage compartment of the kimchi storage forcibly circulating the cold air supplied to the storage compartment By evenly distributing, it is to provide a structure for improving the temperature deviation in the storage room of the kimchi storage to reduce the temperature deviation inside the storage room as much as possible to maintain the freshness of food in the upper storage room for a long time.

As shown in FIG. 2, the kimchi reservoir to which the present invention is applied includes a main body 11, a storage chamber 12 configured inside the main body 11, and a cooling device under the storage chamber 12. It is a conventional kimchi storage having a machine room 14 and a door 13 covering the storage room 12 with an upper end of the main body 11.

Here, the present invention is a forced air generating device (A) for generating a forced air flow to forcibly circulate the cold air in the storage chamber 12 to eliminate the temperature deviation in the storage chamber 12, the door 13 It is configured to be installed on the bottom of the.

As shown in FIG. 3, the forced air generating device A according to the preferred embodiment of the present invention is characterized by vibrating the vibrating member 30 left and right using the electromagnet 20.

That is, when looking at the forced air generating device using the electromagnet 20, the vibrating member 30 with the corresponding magnet 40 is attached to the bottom surface of the door 13, the left and right flow of the vibrating member 30 An electromagnet 20, a center pin 33 for the left and right vibration of the vibrating member 30, and a fixing member 50 for supporting and fixing the vibrating member 30 at the outermost part of the component is combined configuration It becomes the structure that becomes.

3 and 4, the vibrating member 30 has a fork-shaped magnetic portion 34 to which the corresponding magnet 40 is attached, and an arm extending downward from the magnetic force portion 34. And a diaphragm 31 formed at the lower end of the arm 32 and having an area sufficient to generate forced convection directly in the storage chamber 12, wherein the vibrating member 30 vibrates from side to side. A fastening hole 35 to which the center pin 33 is fitted is formed on the arm 32.

Accordingly, the center pin 33 is inserted into the fastening hole 35 so that the vibrating member 30 can vibrate left and right by the center pin 33.

In addition, the electromagnet 20 is configured such that the N, S poles of the electromagnet 20 are alternated by periodically supplying an alternating current. In this case, when supplying a direct current, the power supply direction is changed through a circuit configuration. It is preferable to configure so that the N and S poles of the electromagnet 20 may be alternated periodically.

Of course, the electromagnet 20 is located inside the fixing member 50 and the magnetic force part 34, that is, the receiving space 60 of the electromagnet.

At this time, the corresponding magnet 40 is attached to both side surfaces of the magnetic force portion 34 of the vibration member 30, respectively, the electromagnet 20 and the corresponding magnet 40 has a predetermined interval so that the magnetic force can act Keeping up.

In addition, the fixing member 50 forms a space so that the arm 32 and the diaphragm 31 of the vibrating member 30 are suspended downward to allow left and right vibration, and is fixedly attached to the bottom surface of the door 13. .

In addition, when the door 13 is opened by installing the contact switch 70 between the main body 11 and the door 13, the electromagnet 20 does not operate while the power supply is cut off, and thus the vibration member 30 temporarily. Is configured to stop.

Of course, in the case of the installation position of the contact switch 70, it is shown that the upper surface of the storage compartment 12 is provided on the accompanying drawings, but is not limited thereto and may be switched depending on whether the door 13 is opened or closed. You just need to be in place.

Looking at the operating state of the forced air generating device (A) using the electromagnet according to the invention having such a configuration as follows.

As described above, when the conventional kimchi reservoir supplies cold air to the storage compartment 12 through the operation of the refrigeration system with the door 13 closed, the cold air is circulated only by natural convection in the sealed storage compartment 12. Because cold air is driven toward the lower side of the storage compartment 12, a temperature deviation occurs between the upper and lower portions of the storage compartment 12.

Accordingly, as shown in FIG. 5, in the state in which the forced air generating device A is configured in the door 13, cold air is supplied to the storage chamber 12 and power is supplied to the forced air generating device A according to the present invention. When supplied, the vibrating member 30 by the magnetic force of the electromagnet 20 and the corresponding magnet 40 vibrates the air flow in the upper part of the storage chamber 12 by vibrating the left and right at regular intervals around the center pin 33. As it is disturbed, the upper hot air is moved to the lower part, and the cold air at the lower part is moved to the upper part to continuously supply cold air to all areas inside the storage chamber 12 evenly.

In more detail, when power is supplied to a portion of the electromagnet 20 of the forced air generating device A immediately after the door 13 is closed, a change in polarity between the electromagnet 20 and the corresponding magnet 40 may occur. According to the attraction force and repulsive force is repeatedly acting, thereby vibrating member 30 is to maintain the left and right vibration continuously.

Forced convection occurs in the sealed storage chamber 12 due to the left and right vibration of the vibrating member 30, the cold air of the upper and lower parts can be circulated to reduce the temperature deviation of the upper and lower parts, the door 13 Even though heat transfer by the outside air occurs in the portion is constantly circulating the cold air will be able to maintain a more effective constant temperature inside the storage compartment (12).

Of course, when no voltage is applied to the electromagnet 20, the vibration member 30 does not operate due to no attraction and repulsive force, and the vibration only when a constant voltage is periodically applied to the electromagnet 20. The member 30 vibrates left and right for a long time by the repetitive action of the attraction force and the repulsive force.

As described above, according to the present invention, by constructing a forced air generating device including a vibrating member for oscillating left and right in the storage chamber of the kimchi storage, and an electromagnet for operating the vibrating member, As the airflow of the upper part of the storage compartment is disturbed, forced convection occurs in which the hot air in the upper part of the storage compartment moves to the lower part and the cold air of the lower part moves to the upper part.

That is, by forced convection of the cold air in the storage compartment as described above, the cold air is evenly distributed in all areas inside the storage compartment, thereby minimizing the temperature deviation in the storage compartment, which is a problem of the prior art, and thus maintaining the constant.

Therefore, the forced air generating device configured in the door of the kimchi storage is a very useful invention having the effect of maintaining the freshness of the food stored in the kimchi storage and long-term storage compared to the conventional kimchi storage.
