First, FIG. 2 shows the main body cabinet 21 of the refrigerator, and only the outer box 22 and the inner box (FIG. 2 shows only the inner box 23 for the refrigerating chamber and the inner box 24 for the freezer in the middle compartment). Insulating material is filled by injecting and foaming the heat insulating material 25 in an undiluted state.

In the refrigerating chamber 26 constituted by the inner box 23 for the refrigerating chamber, the shelf 27 is installed in multiple stages, and the lowermost portion of the refrigerating chamber is chilled. partial) 28 and a water supply tank chamber 29 for an ice maker. In addition, the duct cover 30 is provided in the central part of the inside of the refrigerating chamber 23. The duct cover 30 is for supplying the cold air sent from the cooler chamber (not shown) to the refrigerating chamber 26. The duct cover 30 has a cold air discharge port 31 corresponding to each stage of the shelf 27. As shown in FIG. 1, the duct forming member 33 which forms the tank duct 32 extended up and down is provided.

On the other hand, a recess 34 is formed in the inner box 23 constituting the inner wall surface portion of the refrigerating chamber 26, and the duct forming member 33 is accommodated in the recess 34 so that the duct cover 30 is provided. It is installed so as to have a flat shape.

4 and 5 show the installation structure of the duct cover 30 to the inner box 23 and, as can be clearly seen in FIGS. 4 and 5, the end edge of the duct cover 30. The contact portion 30a is removed from the portion, and the elastic nail portion 35 as the locking portion is formed in four places, for example, and the inner box 23 has the nail receiving concave portion as the engagement portion at both sides of the recess 34. 36 are formed in equal numbers, and the elastic nail parts 35 are held in the nail rest portions, respectively. In addition, an installation hole 37 is formed in one central position of the duct cover 30, and one screw 38 is screwed into the inner box 24 from the installation hole 37 by a screw type coupling. ) Is installed in the inner box (23).

In addition, the duct-forming member 33 is thinner because the thickness of the recess 34 of the inner box 23 (remains the thickness of the residual insulation wall by the heat insulating material 25 of the main cabinet 21 to the maximum). T1) (see FIG. 1) is made smaller than the thickness T2 (see FIG. 9) of the conventional duct forming member 4, and the width W1 is larger than the width W2 of the conventional duct forming member 4. The required ventilation cross-sectional area of 32 is ensured, and the width W3 of the duct cover 30 is also set larger than the width W4 of the conventional duct cover 2 at this stage.

Thus, the damper device 39 is provided at the inner side of the lowermost part (chilled partial 28) of the refrigerating chamber 26 shown in FIG. 3 with respect to the duct 32. As shown in FIG. Although the damper device 39 is not shown in detail, the damper plate 40 is operated by the operation of a gas pressure or a motor which changes in accordance with the temperature of the refrigerating chamber 26, and the passages shown in FIGS. 41) opens and closes the opening and closing port 42 connected to the cooler chamber (not shown), thereby supplying the internal air when the temperature of the refrigerating chamber 26 is higher than or equal to the predetermined temperature, and interrupting the supply of cold air when the lower than the predetermined temperature. .

The baffle surface 43, which folds the damper device 39 with the opening and closing port 42 of the damper plate 40, faces the inside of the refrigerator, and the cold air outlet 44 is located outside the refrigerator. The duct 32 communicates with the cold air outlet 44 provided in the lowermost part of the refrigerating chamber 26. In this relationship, the duct forming member 33 and the duct cover 30 together prevent the lowermost portions 33a and 30b from being pushed into the same refrigerator as the conventional duct forming member 4 and the duct cover 2. .

In addition, the duct-forming member 33 is overlapped with the damper device 39 in the front-rear direction. In this state, the damper device 39 is tightened and fixed by a screw 45 advanced from the front of the inside of the refrigerator. .

In addition, in Fig. 1, the recessed portion 34 of the inner box 23 and the small recessed portion 46 in the rear (outside the refrigerator) direction as the lead wire accommodating portion formed on the lateral side of the accommodating portion 33 of the duct forming member 33 are shown. The lead wires 48 contacting the damper device 39 and the power circuit board 47 (see FIG. 3) provided on the back of the refrigerator outside the duct 32 are shown in FIG. It is stored and installed from a vinyl band with a wire in it.

In addition, in the heat insulation wall of the main cabinet 21, a heat dissipation pipe 49, which is a part of the condenser of the refrigeration cycle, is provided at the rear side of both side end portions having a large thickness and avoiding the inner side of the concave portion 34 of the inner box 23. .

2nd 4 shows a back lamp 50 in a refrigerator for lighting the refrigerating chamber 26 provided at the top of the duct cover 30.

By the way, when comprised as mentioned above, the duct cover 30 is formed in the recessed part 34 formed in the inner box 23 which comprises the inner wall surface part of the refrigerating chamber 26 in the duct forming member 33 located in the inner side. Since the housing is installed in the inner box 23, the duct cover 30 itself does not protrude in the refrigerator like the conventional duct cover 2 that is installed in the flat shape on the inner wall surface of the refrigerating chamber 26. In this way, the effective contents used for storing the articles in the refrigerator can be increased, and the appearance can be advantageous because it does not put pressure on the user.

In addition, in the case of the above configuration, the duct cover 30 is installed in the inner box 23 by latching the distal edge portion by the elastic nail portion 935 which is the locking portion and the nail receiving concave portion 36 which is the locking portion, and thus is installed in the inner box 23. It is easy to deform | transform, and it can correct and install it by the stop. Therefore, since the duct cover 30 can be installed in intimate state so as not to fall from the inner wall surface part of the refrigerating chamber 26, it can make it more preferable externally. In this case, the attachment is mainly performed by the elastic nail member 35 and the nail rest concave portion 36, and the price can be reduced as much as the number of the screws 38 can be reduced.

In addition, the nail receiving concave portion 36 is formed in a so-called undercut shape, and it is difficult to form a flat portion of the inner box 23, but the concave portion 34 is formed by forming the concave portion 34. It can be easily formed in combination with (usually major molding). In addition, mold removal, etc. in that case can also be performed easily using a slit, etc. which slide in the direction of the center of the recess 34.

For the damper device 39 which controls the supply of cold air to the duct 32 formed by the duct forming member 33, the baffle surface 43 of the damper plate 40 faces the refrigerator side and the cold air discharge port 44 ) Is installed in an arrangement located outside the refrigerator, and the duct 32 is interlocked with the cold air outlet 44 of the damper device 39 so that the duct forming member 33 and the duct cover 30 are together with the lowermost portion 33a. ), 30b may be so as not to protrude into the refrigerator, such as the conventional duct forming member 4 and the duct cover (2). As a result, the effective contents in the refrigerator can be further increased, and the appearance can be further improved.

In addition, the duct-forming member 33 cannot be overlapped in the vertical direction like the conventional duct-forming member 4 with respect to the damper device 39, but is overlapped in the front-rear direction and the damper device 39 is in this state. Is fixed by the screw 45 pushed forward from the inside of the refrigerator, and the fixing force of the screw 45 effectively acts to strengthen the joining of the duct-forming member 33. Therefore, even if irregularities occur in their front and rear attachment apparatuses, they can be closely bonded and the supply of cold air can be prevented from occurring so that no need for a spare member such as a sealing member is needed.

In addition, the recess 34 of the inner box 23 is formed with a small recess 46 as a lead bow lead portion, and the power supply is provided along the duct 32 in the damper device 39 and on the backside of the refrigerator. Since the lead wire 48 for connecting the circuit board 47 portion is accommodated and installed, the lead wire 48 does not move under the foam pressure of the heat insulating material 25. Therefore, the lead wire 48 is stopped in a hidden position by the duct cover 30 so that it does not deform to the wall surface of the refrigerating chamber 26 outside the duct cover 30, and furthermore, the reinforcing plate like the conventional one Since it can achieve it without needing in particular, the price reduction of a refrigerator can be realized.

Also, in this case, since the small recess 46 may be formed within the depth of the recess 34 of the inner box 23, the small recess 46 may be prevented from protruding into the refrigerator. The effect of increasing the effective content in the refrigerator and making it desirable in appearance can be avoided.

In addition, the heat dissipation pipe 49 which is a part of the condenser of the refrigeration cycle is installed in the heat insulation wall of the main cabinet 21 to avoid the inner side of the concave portion 34 of the inner box 23 and to avoid the inner side of the inner side 23. Its adverse effect in the refrigerator can be more reliably prevented by the large portion of the insulating wall thickness.

7 shows a second embodiment of the present invention, in which the small concave portion 50 serving as the lead bow portion instead of the small concave portion 46 is adjacent to the concave portion 34 of the inner box 23. The part (covered by the duct cover 30) is shown to be formed in the front (inside refrigerator) direction with the said small recessed part 46 upside down.

Even in this way, the lead wire 48 is accommodated and installed in the small recess 50, and the lead wire 48 moves under the foam pressure of the heat insulating material 25, as described above. Therefore, the problem of the deformation of the wall surface part of the refrigerating chamber 26 by the lead wire 48 can be solved without requiring a reinforcement board etc. especially as mentioned above.

In addition, this invention is not limited only to the Example mentioned above and shown in the figure, It can change and implement suitably in the range which does not deviate from the summary.
