Description

Cold supply of the refrigerator

The present invention relates to a refrigerator, and in particular, by controlling the cold air supply method and the air composition differently according to the type of vegetables and fruits in the vegetable compartment and the fruit compartment to be formed separately, respectively, it is possible to improve storage and maintain freshness of the foods stored in the vegetable compartment and the fruit compartment. It relates to a cold air supply of the refrigerator.

The cold air supply apparatus of the conventional refrigerator is shown in FIG.

The cold air supply device is a cold air supply port (2) for supplying the cold air generated in the condenser by the fan to the inside of the refrigerator (1), and the vegetable is stored and supplied with the cold air supplied from the cold air supply port (2) And a vegetable storage chamber (4) for contacting cold air with fruits, and a vegetable storage container (4) inserted into the vegetable chamber (3) to accommodate vegetables and fruits.

In the conventional refrigerator 1 having the above-described configuration, the cold air discharged from the cold air supply port 2 formed in the refrigerating compartment is formed through natural convection through a gap between the cover forming the vegetable compartment 3 and the vegetable storage container 4. Cold air is circulated to the vegetable compartment.

However, the cold air circulated to the vegetable chamber (5: 5 ° C.) causes cold damage to vegetables by directly contacting the vegetables. Especially, the inside of the vegetable chamber 3 is more severely cold due to the deflection of cold air. There was a problem that occurred.

In addition, since the dry air of the refrigerating compartment is directly circulated to the vegetable compartment 3, the drying phenomenon of the foods stored in the vegetable storage container 4 of the vegetable compartment 3 is further promoted, so that not only the shelf life of the vegetable but also many ideas on the evaporator are obtained. There was also a problem that the heat exchange efficiency is lowered.

In addition, since the temperature and air composition are controlled in a constant manner regardless of the type of foodstuffs stored in the one-piece vegetable chamber 3, it becomes an unsuitable state in terms of food storage.

In addition, since the cold air supply is insufficient at the lower end of the refrigerating chamber door of the refrigerator 1, the supply of cold air supplied to the door shelf is insufficient, and thus there is a problem in that the storage of food stored in the door shelf is insufficient.

In order to solve such a conventional problem, the present invention is to separate the vegetable compartment and fruit compartment of the refrigerator separately to maintain the temperature of the vegetable compartment and fruit compartment by indirect cooling method to improve the storage and freshness of the stored food, etc. to provide.

The configuration of the present invention will be described in detail with reference to FIGS.

In order to maintain freshness according to the type of vegetables stored in the refrigerator 118, the vegetable compartment 109 is formed separately from the fruit compartment 114, and is connected to the connection pipe of the condenser to supply cold air to the vegetable compartment 109 By indirectly inverting the supply duct 102 and the cold air supplied from the supply duct 102 to the vegetable chamber 109, it is possible to prevent coldening of the vegetables stored in the vegetable storage container 108 and at the same time lower the temperature of the vegetables. Cold air supply means to maintain and remove the metabolism gas generated in the bulbs and fruits inside the fruit storage container 115 is formed separately from the vegetable storage container 108 of the vegetable compartment 109 to remove bulbs and fruits It is equipped with a means for removing metabolic gas that can be stored freshly for a long time.

In addition, the cold air supply means is coupled to the upper portion of the vegetable chamber 109 and the cold air conduction box 101 for conducting cold air supplied through the connecting duct 102 to the vegetable chamber 109, and the cold air conduction box 101 And a plurality of supply holes 107 for supplying cold air that has passed through the inside of the cold air conduction box 101 to the shelf 117 of the door 116, and the cold air conduction box 101. In the state of absorbing moisture evaporated by the respiration of vegetables in the inside and the supply of cold air is stopped, water absorption and evaporation means is provided to prevent the drying phenomenon of vegetables by re-evaporating the absorbed cold air into the vegetable chamber 109.

In addition, the water absorption and evaporation means is a cold air conduction box in order to prevent the cold air supplied to the upper layer 103 in the cold air conduction box 101 is directly supplied to the vegetable storage container 108 in communication with the lower layer 104. A diaphragm 106 formed at the central portion of the 101 and a moisture absorbing member 105 coupled to the central portion of the diaphragm 106 were provided.

And, the metabolic gas removing means is coupled to the outlet duct 112 and the outlet duct 112 connecting the outside and the cold air conduction box 101 that is seated on the upper side of the fruit compartment, the fruit storage container 115 Equipped with a gas removal filter 113 that can adsorb metabolic gases such as ethylene and carbon dioxide generated from fruits and bulbs.

The operation of the present invention thus described will be described.

First, foods typically stored in the vegetable compartment of the refrigerator 118 may be roughly classified into vegetables and fruits.

In other words, the vegetables are referred to as leaf species such as lettuce, cabbage, spinach and the like, while the leaf is stored, the drying phenomenon occurs by evaporation of moisture by its own respiration.

The freshness of the leaf body is most sensitive to the freshness is lowered.

In addition, the fruits, apples, pears, grapes, strawberries, and vegetables (bulbs), radish, cucumber, carrots, tomatoes, etc. during storage is ripened by metabolic gases such as ethylene and carbon dioxide, leading to fruit and vegetable Is rapidly lowered.

Therefore, in the present invention, the vegetable chamber 109 and the fruit chamber 114 are separately formed as shown in FIG.

In addition, the leaf storage is stored in the vegetable storage container 108 of the vegetable chamber 109 and the bulbs and the like are stored separately in the fruit storage container 115 of the fruit chamber 114, so that the freshness of the food can be maintained satisfactorily. do.

In addition, since the vegetable compartment 109 and the fruit compartment 114 separately stores the vegetables and the fruits, it is not only convenient to use, but also prevents tissue destruction of the vegetables since the tissues are not physically damaged due to the handling of the fruits. Long-term storage.

On the other hand, the cold air supply path of the cold air generated in the refrigerator 118 is supplied to the inside of the cold air conduction box 101 seated on the upper side of the vegetable chamber 109 and the fruit chamber 114 through the supply duct 102. .

The cold air supplied into the cold air conductive box 101 is discharged to the supply hole 107 of the tip portion along the upper layer 103 in the cold air conductive box 101.

At this time, the cold air supplied to the upper layer portion 103 of the cold air conduction box 101 is in contact with the diaphragm 106 that separates the upper and lower layer portions 103 and 104, and transmits cold air so that the temperature of the diaphragm 106 is increased. It goes down.

In addition, the cold air of the diaphragm 106 is indirectly conducted to the lower layer 104 to be in a state of being conducted to the vegetable chamber 109 which is in communication with the lower layer 104, and the vegetable storage container coupled to the vegetable chamber 109 ( 108) is in a state of conduction to the leaves.

Therefore, it is possible to maintain the temperature of the vegetables at low temperatures without the phenomenon of cold by indirect conduction of cold air.

In addition, the evaporated water generated by the respiration of the vegetables stored in the vegetable storage container 108 of the vegetable chamber 109 is moved to the outside by the heat deviation of the upper layer 103 and the lower layer 104 in the cold air conduction box 101. 3 is absorbed by the moisture absorbing member 105 coupled to the diaphragm 106 without exiting.

As described above, when the compressor stops operating in the state in which the moisture absorbing member 105 has evaporated water absorbed, the moisture absorbed by the moisture absorbing member 105 is re-evaporated into the vegetable storage container 108 of the vegetable chamber 109. Maintaining a high humidity environment at (109) prevents the drying phenomenon of vegetables (leaflets) and can be stored for a long time.

In addition, the bulbs such as fruits and vegetables stored in the fruit storage container 115 of the fruit compartment 114 is supplied with cold air in the refrigerating compartment as before through the gap between the fruit compartment 114 case and the fruit storage container 115.

Then, metabolized gases such as ethylene and carbon dioxide generated by the bulbs stored in the fruit chamber 114 are decomposed while adsorbed to the gas removal filter 113 mounted at the outlet duct 112 inlet of the cold air conduction box 101. Through the discharge duct 112, as shown in Figure 4, it is possible to store bulbs, such as fresh for a long time.

On the other hand, the extra cold air indirectly heat exchanged to the vegetable compartment 109 through the upper layer 103 in the cold air conduction box 101 is circulated to the shelf 117 of the door 116, thereby turning the shelf 117 of the door. The food stored in the can be cooled.

In this way, the present invention can prevent cold damage due to cold contact of foods stored in the vegetable compartment by special management of the separate vegetable compartment by indirect cooling rather than direct cooling.

And, by absorbing the evaporated water generated in the vegetable by the moisture absorbing member coupled to the plate of the vegetable chamber, the absorbed moisture can prevent the drying of the vegetable by re-evaporating when the temperature of the vegetable chamber rises.

In addition, by removing the metabolic gas generated in the bulbs stored in the fruit chamber with a gas removal filter to prevent oxidation and ripening can increase the freshness of the bulbs.

It is possible to smoothly supply cold air to the shelf at the bottom of the door, which is difficult to supply cold and cold air, and thus has a useful effect of improving the cooling performance at the same time as to ensure uniform cooling of the entire refrigerator.
