Abstract

The present invention relates to a device for preventing the temperature rise of the door pocket part of the refrigerator. In the related art, a separate cold air supply device for preventing the temperature rise of the refrigerated object stored in the door pocket due to frequent opening and closing of the refrigerator compartment door is not frequently installed. Refrigerated foods that need to be stored for more than 1 ~ 2 weeks due to the decrease in freshness of food stored in the door pocket after the door is opened or opened for a long time cannot be stored in the refrigerator compartment door pocket, but should be stored on the shelves in the refrigerator compartment. In the freezer door pocket, there has been a problem that storage of frozen foods to be stored for a long time should be avoided. To solve this problem, a pocket cover is installed on the upper side of the door pocket and the side duct inside the inner box is in communication with the cold air inlet of the door pocket. It extends to the cold air discharge hole on the front and directly cools the door By supplying the device, the temperature of the door pocket part due to frequent door opening and closing may prevent the freshness of the food stored in the door pocket from being lowered.

Description

Temperature rise prevention device of door pocket

The present invention relates to a door pocket of a refrigerator, and more particularly, to a temperature increase prevention device of a door pocket part which prevents a temperature increase of the door pocket part by opening and closing the refrigerating chamber door and maintains a proper temperature to maintain a fresh state. It is about.

In a typical refrigerator, the cold air circulation of the freezer compartment and the refrigerating compartment is operated when the cooling system is operated when the inside of the refrigerator is raised above a certain temperature, and a blower fan is operated so that the cool air in the chiller chamber is supplied from the rear side of the freezer compartment, The process of returning to the cooler side through the return duct and feeding back to the freezer compartment and the refrigerating compartment by the blower fan is repeated repeatedly until it reaches a certain temperature while forming a cold air supply cycle.

1 is a general perspective view showing a door open state of a conventional refrigerator, the cold air circulation of the refrigerating compartment when the temperature of the refrigerating compartment when the refrigerating chamber fan installed on the upper side of the cooler is operated, the cold air in the chiller chamber is the main duct 90 It is guided to the upper side of the refrigerating compartment through the back and is supplied to the inside of the refrigerating compartment through the side duct 80 'installed on the side of the refrigerating compartment.

The supplied cold air is exchanged in the refrigerating chamber and the temperature is increased, and then it is introduced into the return duct to return to the cooler side, and when the process of being cooled in the cooling chamber and supplied to the refrigerating chamber in the same manner is below the predetermined temperature. The cycle will be repeated until.

However, the conventional cold air circulation structure of the refrigerator does not have a separate cold air supply device for preventing the temperature rise of the object to be stored in the door pocket 30 due to frequent opening and closing of the refrigerating chamber door frequently open the door or for a long time In the case of refrigerated foods that need to be stored for 1 to 2 weeks or more due to the deterioration of freshness of food stored in the door pocket 30 after opening, the refrigerator cannot be stored in the refrigerator compartment door pocket 30 and stored in the shelf (3) in the refrigerator compartment. In addition, the storage of frozen food for a long time in the freezer door pocket has been a problem that should be avoided if possible.

The present invention has been made to solve the above-mentioned problems of the prior art, by installing a pocket cover on the upper side of the door pocket and extending the side duct of the inner side to the cold air discharge hole so as to communicate with the cold air inlet of the door pocket directly into the door pocket The technical problem is that by supplying cold air to prevent the decrease in the freshness of food stored in the door pocket by the temperature rise of the door pocket portion due to frequent door opening and closing.

Figure 2 is a full perspective view showing a door open state of the refrigerator according to the present invention,

Figure 3 is a cross-sectional view showing a door pocket portion and a duct structure according to the present invention.

Explanation of symbols on the main parts of the drawings

2: cold room door 3: shelf

10: cold air inlet 15: cold air inlet

20: pocket cover 30: door pocket

40: fixing protrusion 45: fixing groove

80: side duct

In order to achieve the above technical problem, the apparatus for preventing the temperature rise of the door pocket part of the present invention has a handle part formed at the bottom of the front surface, and a pocket cover in which the fixing protrusions are respectively protruded at both ends, and the fixing protrusions are rotatably fitted. Fixing grooves are formed in the inner side and the vertical bead formed in each side of the cold air inlet hole, and the side duct connected from the main duct to the cold air discharge hole formed in the front of the inside of the refrigerating chamber.

Hereinafter, an apparatus for preventing temperature rise of a door pocket according to the present invention will be described in more detail with reference to the drawings.

2 is an overall perspective view showing a door open state of the refrigerator according to the present invention, Figure 3 is a plan sectional view showing the door pocket portion and the duct structure according to the present invention, as shown in Figures 2 and 3, Vertical beads 50 are formed on both sides of the freezing chamber door 2 vertically, and a plurality of door pockets 30 are respectively installed inside the vertical beads 50, and the door pockets 30 are installed. One side of the vertical bead 50 is formed with a cold air inlet hole 10 so that the cold air flows from the side duct 80, the fixing groove 45 is formed in the upper groove.

In addition, the fixing protrusion 40 corresponding to the fixing groove 45 protrudes on both sides so that the pocket cover 20 which is fixed to the fixing groove 45 so as to be pivotally formed has a handle portion 25 at the front lower side. It is formed of a transparent material and the refrigerated object stored therein is distinguishable, and when the refrigerating object is taken out and stored, the pocket cover 20 is lifted up to open.

Side ducts 80 for discharging cold air to each shelf 3 are installed on the side surfaces of the inner box 70 inside the refrigerating chamber. The side ducts 80 communicate with the inner box 70 from the main duct 90. The cold air discharge hole 15 and the cold air inlet hole 10 are extended to the cold air discharge hole 15 on the front of the inner box 70 and the cold air discharge hole 15 is closed. Corresponding to each other is to supply the cold air to the door pocket (30).

Thus, the pocket cover 20 is installed on the upper side of the door pocket 30 to primarily block the temperature rise due to the opening of the refrigerating chamber door 2, and to cool the air in the door pocket 30 through the side duct 80 after opening and closing the door. Since the supply is immediately supplied to the door pocket part to block the rise in temperature by the opening of the door to maintain the proper temperature in the door pocket part.

As described in detail above, the door pocket temperature rise prevention device of the present invention refrigerator has a pocket cover installed on the upper side of the door pocket and extends the side duct of the inner side to the cold air discharge hole so as to communicate with the door pocket through the cold air inlet hole. By supplying cool air directly to the pocket to maintain a proper temperature in the door pocket portion is a useful design that can prevent the freshness of the food stored in the door pocket is lowered.
