Refrigerator

The present invention relates to a refrigerator, and more particularly to an installation structure of a vegetable box that is coupled in a sliding manner in the lower portion of the refrigerator compartment.

In general, the refrigerator is configured to supply the cold air generated from the evaporator of the refrigeration cycle to the storage compartment to maintain the freshness of various foods for a long time.

As shown in FIG. 1, the refrigerator is a storage compartment having an open front in a cabinet 10 constituting an outer body, so that a freezer compartment 11 storing frozen foods and a refrigerating compartment 12 storing refrigerated foods are partitioned. The doors 11a and 12a for opening and closing the freezing chamber 11 and the refrigerating chamber 12 are hinged to the front surface of the cabinet 10.

In the rear of the freezing chamber 11, a separate cooling chamber 20 is formed to generate cold air and to supply the freezing chamber 11 and the refrigerating chamber 12. Here, the evaporator 21 and the freezing chamber 11 which generate cold air are formed. And a circulation fan 22 for introducing air from the refrigerating compartment 12 into the evaporator 21 and forcibly blowing the generated cold air into the freezing compartment 11 and the refrigerating compartment 12. In addition, a freezing chamber duct 40 and a refrigerating chamber duct 41 in which cold air outlet holes 40a and 41a are arranged so as to properly distribute and guide the cold air to the freezing chamber 11 and the refrigerating chamber 12 are installed at the rear side, and the freezing chamber is installed. In the partition 30 which partitions 11 and the refrigerating chamber 12, return ducts 30a and 30b are formed to guide the air sucked by the suction force of the circulation fan 22 to the evaporator 21.

In the freezing chamber 11 and the refrigerating chamber 12, shelves 50 and 51 are fitted in the rail 52 so as to accommodate and store food, and are installed in the horizontal direction. Since the internal space is larger than the freezer compartment 11, the refrigerating chamber 12 is provided with a shelf 51 in multiple stages, and a lower vegetable box 60 configured to store vegetables and the like containing moisture therein. The vegetable box 60 having the handle 61 has a storage space formed therein and is provided in an open box shape at an upper portion thereof, so that cold air does not directly touch vegetables and the like, thereby keeping moisture of food as it is for a long time.

In the refrigerator configured as described above, when the circulation fan 22 is operated, air in the freezing compartment 11 and the refrigerating compartment 12 flows into the evaporator 21 through the return ducts 30a and 30b, which passes through the evaporator 21. While being cold, the air is continuously forced into the freezing chamber 11 and the refrigerating chamber 12 through the freezing chamber duct 40 and the refrigerating chamber duct 41. Accordingly, the food stored in the freezer compartment 11 and the refrigerating compartment 12 are stored in the frozen and refrigerated state, respectively. And if you want to take out the frozen, refrigerated food is to open the hinged door (11a, 12a) to take out.

On the other hand, if you want to take out the food stored in the vegetable box 60, first, after opening the refrigerating chamber door (12a), grab the handle 61 and pull forward. Accordingly, the vegetable box 60 slides forward from the lower part of the refrigerating chamber 12, and in this state, the food stored in the open upper part is taken out and the vegetable box 60 is pushed back.

However, since the bottom of the vegetable box 60 is in a horizontal state and the weight of the vegetables contained therein is increased, the bottom is pressed against the bottom surface of the refrigerating chamber 12. Accordingly, when inserting the vegetable box 60 in the front and rear, not only the interference is not possible to move smoothly, but also in this state to apply a force to move the vegetable box 60, the handle 61 There is a problem that vulnerable parts, such as broken.

Another vegetable box is disclosed to solve this problem, the structure of which is as shown in FIG.

In addition, this is slidably coupled back and forth at the bottom of the refrigerating chamber 12. To this end, the side surface portion of the refrigerating chamber 12 is provided with a rail groove 70 formed to extend in the horizontal direction, the upper roller 62 and the lower portion in the rolling groove in the rail groove 70 on both side rear ends of the vegetable box 60 '. The rollers 63 are provided respectively. The upper roller 62 and the lower roller 63 are axially coupled to each other so that the upper roller 62 is in rolling motion in contact with the upper surface 71 in the rail groove 70, the lower roller 63 is a rail groove In contact with the lower surface 72 of the (70) it is rolling. And the rear end of the rail groove 70 is formed so that the locking step 73 to prevent the rear end of the vegetable box 60 in contact with the rear wall surface of the refrigerating chamber 12 in the process of the vegetable box 60 is retracted. It is. Therefore, the upper roller 62 is in contact with the locking step 73 of the rail groove 70 is prevented from entering any more when the maximum entry of the vegetable box (60).

However, when the vegetable box 60 'is unintentionally pushed by the user, the rolling roller upper roller 62 is strongly rubbed against the locking jaw 73, the noise is generated. That is, since the vegetable box 60 'is moved in the forward and backward direction while rolling, its use is much easier than in the prior art. When the user unknowingly pushes strongly, the upper roller 62 and the lower roller 63 are rail grooves ( While moving along the upper surface 71 and the lower surface 72 of the cloud (70) while entering the high speed. At this time, only when the upper roller 62 hits the locking jaw (73) stops its introduction, severe impact noise is generated due to their strong collision, and in some cases the upper roller 62 and the rail groove (70) This may be damaged.

The present invention is to solve this problem, the main purpose of the present invention is to form a rail groove in the transverse direction on both side walls of the refrigerating chamber, by installing a roller for rolling along the rail groove at the rear end of the upper side of the vegetable box It is to provide a refrigerator, which is easy to access the vegetable box.

And the secondary purpose of the present invention is to install a spring member at the rear end of the rail groove so as to hit the roller at the maximum retracting of the vegetable box, to perform the damping role with its own elastic force of the spring member to reduce the operating noise To provide.

The rear end of the rail groove is characterized in that the spring member is provided in contact with the roller to prevent the vegetable box from being drawn in further.

Hereinafter, one preferred embodiment according to the present invention will be described in detail with reference to the accompanying drawings. Figure 3 is a side cross-sectional view showing the overall structure of the refrigerator according to the present invention, Figure 4 is an enlarged cross-sectional view showing an extraction structure of the vegetable box according to the present invention.

The refrigerator according to the present invention, as shown in these, is formed in the cabinet 100, the freezer compartment for storing the frozen food 110 and the refrigerating chamber 120 for storing the refrigerated food, which is formed by the partition 300 Doors 111 and 121 which are provided to be partitioned up and down are opened and hinged to the front surface of the cabinet 100 so as to be rotatable.

A cooling chamber 200 is formed at the rear of the freezing chamber 110 to provide an evaporator 210 for generating cold air, and a circulation fan 220 as a means for forcibly blowing the generated cold air. The freezing chamber duct 400 and the refrigerating chamber duct 410 in which a plurality of cold air outlet holes 411 and 412 are arranged up and down are respectively installed on the rear side walls of the freezing chamber 110 and the refrigerating chamber 120 to guide the supply of the cold air. After completing the heat exchange operation in the freezer compartment 110 and the refrigerating compartment 120, the air is introduced into the evaporator 210 to be cooled again. The partition 300 has a freezer compartment guide passage 310 and a refrigerator compartment guide passage 320 for the return of cold air. ) Is formed in communication with the installation portion of the evaporator (210).

In addition, the shelves 500 and 510 are installed in the freezing chamber 110 and the refrigerating chamber 120 in a horizontal direction so that various stored foods can be stored and stored in the freezing chamber 110 and the refrigerating chamber 120. Both ends are fitted in the coupling.

In the refrigerating chamber 120 having a relatively large internal space, a shelf 510 is provided as a kankan to store a plurality of refrigerated foods, and a vegetable box 600 is formed in a box at the bottom thereof to prevent cold air from directly contacting the food. .

The vegetable box 600 is kept in a predetermined humidity to keep a predetermined humidity separated from other foods in order to prevent drying of various vegetables or fruits, such as to keep their moisture for a long time to store fresh. The vegetable box 600 having such a function is composed of a side portion and a bottom portion so as to form a storage space therein, and an upper portion thereof is opened, and a handle 610 is provided at the front portion thereof. In addition, the rollers 620 and 630 are axially coupled to both side surfaces of the vegetable box 600, and are clouded out from the bottom of the refrigerating chamber 120. The detailed structure thereof is as follows.

First, both side inner wall surfaces of the lower side of the refrigerating chamber 120 are formed with rail grooves 700 which extend to a predetermined depth in the horizontal direction. An upper roller 620 and a lower roller 630 axially coupled to each other are formed at the rear end of the vegetable box 600, and the upper roller 620 is positioned at the rear end of the vegetable box 600. Since the upper roller 620 and the lower roller 630 are formed on the other side of the vegetable box 600, which is not shown, the upper and lower rollers 620 and 630 are clouded while the vegetable box 600 is in the refrigerating chamber. 120, it becomes slidable below.

And the spring member 800 for limiting the maximum pull-out of the vegetable box 600 is installed in the rail groove 700, which is that when the vegetable box 600 is completely drawn into the refrigerating chamber 120 is no longer coming in It prevents the collision with the rear wall of the freezer compartment 120. The spring member 800 is installed in the rear of the rail groove 700 as a characteristic element of the present invention and consists of a leaf spring bent at a predetermined curvature. Therefore, when the vegetable box 600 is introduced and the upper roller 620 hits the bending portion 810 of the leaf spring 800, the insertion of the vegetable box 600 is stopped. At this time, the leaf spring 800 performs a damping function with its own elastic force, so that little noise is generated due to friction with the upper roller 620, which will be described again in the operation description.

Next, the operation and effects of the refrigerator configured as described above will be described. First, when the circulation fan 220 is rotated, the cold air generated in the evaporator 210 is supplied to the freezing chamber 110 and the refrigerating chamber 120 through the freezing chamber duct 400 and the refrigerating chamber duct 410 to cool the stored food. While being heat-exchanged, the heat-exchanged air is again re-cooled into the evaporator 210 through the freezer compartment guide passage 310 and the refrigerating compartment guide passage 320 and then supplied to the freezer compartment 110 and the refrigerating compartment 120, thereby freezing compartment 110. ) And the food stored in the refrigerating chamber 120 to maintain a fresh state for a long time.

On the other hand, the stored foods such as vegetables stored in the vegetable box 600 is freshly stored to prevent direct contact with cold air, in order to take out or store the food stored therein, grab the handle 610 provided on the front and pull forward.

Therefore, while the upper roller 620 and the lower roller 630 axially coupled to the rolling motion along the upper surface 710 and the lower surface 720 of the rail groove 700, the vegetable box 600 is the refrigerator compartment 120 Exposed to the outside through the opening, the storage and withdrawal of the food is made through the open top of the vegetable box 600. And when the vegetable box 600 is pushed in, the upper roller 620 enters the inner roller while the lower roller 630 moves along the rail groove 700, and the upper roller 620 is the bending portion of the leaf spring 800 ( When it comes in contact with 810, the vegetable box 600 no longer enters.

That is, the entry and exit of the vegetable box 600 is easily carried out by sliding because the upper roller 620 and the lower roller 630 is a cloud movement, if pushed strongly this the upper roller 620 and the leaf spring (800) The contact is stopped by contact. At this time, the upper roller 620 is in strong contact with the bending portion 810 of the leaf spring 800, due to its elastic force of the leaf spring 800, such a shock is absorbed by the shock absorbing the noise due to the collision It does not occur.

As described above in detail, the refrigerator according to the present invention forms a rail groove in the transverse direction on both side walls of the refrigerating chamber, and installs a roller moving along the rail groove at the rear end of the upper side of the vegetable box, and also of the rail groove. A spring member was formed to limit the maximum entry of the vegetable box by hitting the roller at the rear end.

Therefore, the rolling movement of the roller is made smoothly coming out of the vegetable box, the damping function by the self-elastic force of the spring member when the maximum entry of the vegetable box has the advantage that the impact noise is significantly reduced.
