The problem to be solved by the invention

However, in recent years, there has been a tendency to increase the actually accommodable internal volume of the refrigerator by concentrating on the arrangement of the components of the refrigerator.

The containers included in the conventional drawer-type storage room are mounted only on the rail device. In this way, if the volume of the container increases, the contents stored in the container also increase, and the load acting on the rail device also increases. If the drawing door is opened, the load will further act on the rail device, and in particular, the stress acting on the end portion serving as the mounting portion of the rail device and the drawing door will increase.

In addition, since the amount of load acting on the rail device increases, the rail device may deform and fall inward. In this state, the sliding door cannot be moved smoothly in the front-rear direction.

This is because only the rail device 202 supports the container 206 linked to the opening of the drawing door when the drawing door is opened to the maximum. Moreover, since the drawing door, which is thermally insulated and foamed inside, is located at the end of the track device 202 , the load of the drawing door 201 also acts on the end of the track device 202 in addition to the load of the container 206 . In addition, from the viewpoint of energy saving, a vacuum heat insulating material may also be buried in the drawing door 201, and the load on the rail device 202 may be further increased. Therefore, when the opening and closing operation of the drawing door 201 is repeated for a long period of time, the rail device 202 is deformed, and even if the drawing door 201 abuts on the opening of the vegetable compartment 103 or the freezer compartment 104, the opening of the drawing door 201 will be damaged. Therefore, the opening cannot be completely closed, or the opening cannot be sealed by the sealing portion (not shown) of the drawing door 201, and the cold air in the room may leak, and cooling to a predetermined temperature may not be possible.

The present invention is to solve the above-mentioned existing problems, and its purpose is to provide a refrigerator with a drawer-type storage room, which can ensure a large actual storage volume in the drawer-type storage room, and can especially distribute the effect on the track device. The load on it can reduce the skew of the sliding door caused by the deformation of the track device, reduce the imbalance of the door, and ensure the cooling performance. Moreover, it aims at providing the refrigerator which suppresses the clearance gap of the sealing part by the imbalance of a door, and ensures cooling performance.

The method used to solve the problem

In order to solve the above-mentioned conventional problems, the refrigerator of the present invention includes: a main box body composed of an inner box, an outer box, and a heat insulating material filled between the inner box and the outer box; A drawer-type storage room with a front opening in the inside of the box; a sliding door that closes the front opening of the storage room in a freely openable and closable manner; a partition wall that divides the storage room of the main box; a track device, which It has a fixed track and a moving track, and is fixed to the inner wall of the inner box in the state where the fixed track and the moving track are assembled in advance, and the distance between the drawing door and the main box body is Connected in a freely telescopic manner, the container provided inside the storage room can be moved back and forth. In this refrigerator, the rail device is connected below the central part in the vertical direction of the drawing door and in the left-right direction. Both ends are attached to a rail holding member arranged on the side of the heat insulating material of the inner box so as to hold the left and right ends near the bottom of the container.

Thus, since the rail device is installed on the left and right ends of the bottom of the container, in the middle of the space from the upper opening of the container to the lower bottom of the container, the unevenness of the container surface formed in the middle can be reduced, and the surface can be formed on a flat surface. Therefore, the size and volume of the container can be increased, and the load acting on the rail device increases due to the increase in the load in the storage container, and the force of falling toward the inside of the box is easy to act. The track device can prevent the inner fall by using the track holding member. In addition, since the track device is installed on the left and right ends of the bottom of the container, it can realize the enlargement and volume increase of the container supported by the track device, and reduce the Skew of the sliding door caused by the deformation of the track device can keep the front and rear opening and closing operations smooth, and can ensure the cooling performance.

In addition, the refrigerator of the present invention includes: a main box composed of an inner box, an outer box, and a heat insulating material filled between the inner box and the outer box; An open drawer-type storage room; a sliding door that seals the front opening of the storage room in a freely openable and closed manner; a partition wall that divides the storage room of the main box body; a track device that has a fixed track and a moving track , and in the state where the fixed track and the moving track are pre-assembled, they are fixed on the inner wall of the inner box, and are connected in a freely telescopic manner at the interval between the drawing door and the main box body , capable of moving a container equipped inside the storage room back and forth; a door frame fixed to the drawing door and engaged with the rail device to hold the container; and fixing the door frame to the drawing door In this refrigerator, the reinforcing plate extends along the vertical direction of the drawing door and is integrally formed, the lower part of the reinforcing plate fixes the door frame, and the upper part engages the said container.

As a result, the strength of the drawing door can be ensured and it can be prevented from being twisted in the left-right direction. Therefore, it is possible to suppress gaps in the sealing portion caused by the imbalance of the door and ensure cooling performance.

Invention effect

The refrigerator of the present invention can reduce the large actual storage space and the unbalance of the door in the drawer-type storage room, and ensure the cooling performance.

If the installation part of the drawing door 201 and the top rail 203 is located at the lower part of the drawing door 201, then, when the upper part of the drawing door 201 is pulled out or pushed back, the moment acting on the installation part is relatively large, However, in this embodiment, the first fixing unit 301 or the second fixing unit 303, or both of the first fixing unit 301 and the second fixing unit 303 are set above the installation part to fix the container 206. Therefore, the effect on the installation part Since the moment becomes small, the mounting portion of the top rail 203 can be protected from damage. That is, in this embodiment, by providing the first fixing unit 301 and/or the second fixing unit 303 to draw the door 201, the position of the fulcrum of the pulling force can be positioned upward.

In addition, as described above, the first fixing unit 301 is formed separately from the inner panel 211, and the second fixing unit 303 is integrally formed with the inner panel 211, especially the first fixing unit that forms the fixing structure of the front flange portion 206a of the container 206. The unit 301 is formed of a metal member different from the inner panel 211, so that even if stored items are put into the container 206, the unit 301 can maintain a fixed state with the container 206 even when the drawing door 201 moves. In addition, the second fixing unit 303 is integrally formed with the inner panel 211, whereby the number of parts can be reduced.

6 is a cross-sectional view showing a state in which containers are arranged between rail units of the refrigerator in Embodiment 1 of the present invention from the back side.

As shown in FIG. 6, the container 206 is a container for accommodating vegetables, bottled drinks, frozen food, etc., and is a resin box with an open top. The container 206 has a narrow width portion 261 having a narrow width so that inward-facing stepped portions 262 are formed at both ends of the lower portion. The narrow portion 261 of the container 206 is arranged between the two top rails 203 , and the stepped portion 262 is placed on the upper surface of the door frame 205 to be supported by the top rail 203 .

Moreover, the narrow part 261 which is the bottom surface of the container 206 is arrange|positioned above the rail apparatus 202, and can move along the front-back direction.

In this way, since the top rail 203 is provided at both corners of the lower portion of the drawing door 201 , the narrow portion 261 that must be formed in the container 206 can be shortened as much as possible. Therefore, the container 206 can adopt a shape with a storage volume as large as possible.

7A, 7B, and 7C are enlarged views of main parts showing the arrangement of rail devices and containers of the refrigerator in Embodiment 1 of the present invention.

In the present embodiment, as shown in FIG. 7A , the container 206 has a narrow width portion 261 at both ends of the lower portion such that step portions 262 facing inward are formed along the depth direction of the container 206 . 7B and 7C, the side of the container 206 is roughly shaped as a straight plate, the container 206 is not provided with a stepped portion 262, and the track device 202 is supported on the sides of the left and right ends of the bottom of the container 206 (see FIG. 7B ), or It may also be supported below the left and right ends of the bottom of the container 206 (see FIG. 7C ). In addition, FIG. 7A, FIG. 7B, and FIG. 7C show the positional relationship between the rail device 202 and the container 206, and the door frame 205 is omitted and not shown.

In the case of FIG. 7A, on the stepped portion 262 provided on both sides of the container 206, as shown in FIG. The front protrusion 206b of the container 206 and the rear protrusion 206c formed on the rear side of the container 206 are formed, and these protrusions are inserted into the fixing holes 205a, 205b formed on the door frame.

The fixing hole 205a may have a notch shape, and the front protrusion 206b is inserted into the fixing hole 205a for positioning, and the rear protrusion 206c is inserted into the fixing hole 205b formed at the rear of the door frame 205 .

As shown in FIGS. 4 and 8 , if the rear protrusion 206 c is formed in a shape inclined downward toward the rear of the door frame 205 , easy removal from the state inserted into the fixing hole 205 b can be prevented.

In particular, as described above, in the state where the front flange portion 206a of the container 206 is fixed to the drawing door 201 at the front side, the rear side protrusion 206c is fixed to the door frame 205 at the rear side. The rail 202 attached to the lower portion of the sliding door 201 and the attachment portion of the drawing door 201 are not strong enough to smoothly open and close the drawing door.

That is, since the moment acting on the mounting portion becomes smaller, it is possible to protect the mounting portion of the top rail 203 or the mounting portion of the rail fixing portion from being damaged. That is, in this embodiment, the front flange portion 206a of the container 206 is fixed on the drawing door 201 provided with the first fixing unit 301 and/or the second fixing unit 303, and the rear side protrusion of the container 206 is 206c is inserted and fixed in the fixing hole 205b provided in the door frame 205, whereby the position serving as the fulcrum of the pulling force can be positioned behind the drawing door 201. FIG.

Next, as shown in FIG. 9 , the rail mounting portion 223 integrally formed with the casing rail 222 is provided so as to be in contact with the side surface of the inner box 110 , and fixed to the side of the inner box 110 with screws 400 .

At this time, since the inner box 110 as the mounting surface is mainly molded with resin, even if the screws are directly fixed to the inner box 110, the strength capable of withstanding the load acting on the rail device 202 cannot be ensured. Therefore, the rail apparatus 202 attaches the rail attachment part 223 to the rail holding member 270 embedded in the heat insulating material 111 via the inner box 110 as a means for securely fixing the rail apparatus 202 .

The rail holding member 270 is mainly formed of a metal material such as iron. In addition, the rail holding member 270 is previously fixed at a predetermined position on the inner surface of the inner box 110, and then embedded in the heat insulating material 111 filled with a foamed heat insulating material between the inner box 110 and the outer box 112. Therefore, the holding force of the rail holding member 270 can be further improved.

Specifically, in the layout of refrigerator 100 , rail holding member 270 is arranged above partition wall 108 that separates freezer compartment 104 formed approximately in the center from vegetable compartment 103 disposed below.

In addition, part A is a perspective view in which rail device 202 and rail holding member 270 for holding container 206 of freezer compartment 104 are attached to inner box 110, and FIG. 10 shows a cross-sectional view of main parts of part A. In addition, part B is a perspective view in which rail device 202 and rail holding member 280 for holding container 206 of vegetable compartment 103 are arranged in inner box 110, and FIG. 11 shows a cross-sectional view of main parts of part B.

As shown in Figure 10, the rail holding part 270 is integrally formed with: the rail holding part 270a fixed together with the rail mounting part 223 of the rail device 202 with the screw 400, and the anti-inward dumping unit 270b that prevents the inward falling of the rail device 202 . The anti-falling unit 270b is a horizontal flange integrally formed at the lower portion of the rail holding portion 270a arranged in close contact with the inner box 110 .

Specifically, the inward fall prevention unit 270b is separated from the inner case 110 toward the outer case 112 from the lower portion of the rail holding portion 270a, which is a vertical flange portion formed so as to be in close contact with the inner case 110 from the heat insulating material 111 side. It is formed by bending, and then it is formed by bending downward. In the filled heat insulating material 111, the lateral flange portion of the anti-inverting unit 270b receives the thermal insulating material 111 on the surface, and further, the lateral flange portion is embedded in the thermal insulating material, so the rail holding portion 270a is prevented from falling inward. The unit 270b is fixed, the strength of the rail holding member 270 can be ensured, the rail mounting part 223 can be prevented from falling to the inside of the freezer, and the rail device 202 can be prevented from falling to the inside of the cabinet, so that the sliding door 201 can be opened and closed smoothly.

In addition, the anti-inverting means 270b of the lateral flange may be bent from the lower part of the rail holding part 270a to be integrally formed, or the anti-inverting means 270b may be formed in two places at the upper part and the lower part. Thus, with respect to the rail holding part 270a, the upper and lower lateral flanges receive the heat insulating material 111 on the surface, and the upper and lower lateral flanges are embedded in the heat insulating material, so that the rail holding member 270 can be further secured. The strength can prevent the rail mounting part 223 from falling to the inside of the freezer, thereby preventing the rail device 202 from falling to the inside of the box.

10, the partition wall 108 as the bottom wall of the freezer compartment 104 forms bottom stepped portions 108a on both sides, and the bottom stepped portion 108a is one step higher than the central portion as the reference plane of the partition wall 108, and faces toward the bottom surface. Formed in the direction of depth.

The rail device 202 is arranged on the bottom surface step portion 108a. In addition, a side surface step portion 110 a is formed on a side wall surface portion of the inner box 110 of the fixed rail unit 202 . The side surface step part 110a is formed so that it may be recessed toward the outer case 112 side compared with the upper side wall surface part in the freezer compartment 104, and is made thinner.

The rail mounting portion 223 is fixed to the metal rail holding member 270 with screws 400 so as to sandwich the side stepped portion 110a.

Therefore, the rail device 202 is placed on the bottom surface step portion 108a and fixed to the side step portion 110a with screws, so that the rail device 202 protruding into the storage space can be suppressed, and the space of the container 206 can be increased in the freezer compartment 104. Full width size, reducing dead space.

In addition, since the rail device 202 is assembled on the bottom surface step portion 108a, operability can be improved. In addition, the wall thickness of the partition wall 108 at the portion of the bottom surface step portion 108a is increased, so it is possible to prevent the cooling of the metal rail device 202 located in the freezer compartment 104 from cooling down as the ceiling of the vegetable compartment 103 located at the lower portion. dew condensation on the partition wall 108 on the surface.

Furthermore, since the bottom surface step portion 108a is provided, even if the dew condensation water accumulates in the central portion which is the reference plane of the partition wall 108, the rail device 202 does not come into contact with the dew condensation water. Therefore, the rail device 202 does not become stuck due to dew condensation water freezing. Thereby, opening and closing of the drawing door 201 can be performed smoothly.

In addition, a door frame 205 screwed to the upper surface of the top rail 203 of the rail device 202 is formed, and a stepped portion 262 of the container 206 is placed on the upper surface of the door frame 205 .

In addition, as shown in FIG. 11 , the track holding member 280 formed in the lowermost vegetable compartment 103 is arranged in the heat insulating material 111, and the track holding member 280 consists of a substantially L-shaped vertical flange and a horizontal flange. The rail holding part 280a formed in the upper part is closely attached to the side part and the bottom part of the inner box 110, and is integrally formed with the lateral flange part as the bottom part of the rail holding part 280a, and in the direction away from the inner box 110, as a downward direction. The anti-falling unit 280b formed by the lower flange portion of the rail is integrally formed with the rail holding portion 280a.

The horizontal flange provided on the rail holding member 280 formed in the lowest vegetable compartment 103 is wider than the horizontal flange provided on the rail holding member 270 in the upper freezer compartment 104 .

The anti-inward fall 280b is a lower flange facing downward and is embedded in the heat insulating material 111. Therefore, even if a moment acts on the rail mounting portion 223 in the direction of falling to the inner side of the vegetable compartment, the lower flange will The anti-toppling unit 280b is also stopped by the heat insulating material 111 filled in its lower part, so it can prevent toppling over, further ensure the strength of the rail holding member 280, and prevent the rail device 202 of the vegetable compartment 103 from falling to the inside of the case.

In addition, in Fig. 11, the bottom surface wall 401 of the vegetable compartment 103 is formed with bottom surface stepped portions 401a on both sides, and the bottom surface stepped portion 401a is higher than the center portion as the reference plane of the bottom surface wall 401 by one step, and faces in the depth direction. form.

The rail device 202 is arranged on the bottom surface step portion 401a. In addition, a side step portion 110 a is formed on a side wall surface portion of the inner box 110 of the fixed rail unit 202 . The side step part 110a is formed so that it may be recessed toward the outer case 112 side compared with the upper side wall surface part in the vegetable compartment 103, and the wall thickness becomes thinner.

The rail mounting portion 223 is fixed to the side surface of the metal rail holding member 280 with screws 400 with the side stepped portion 110a interposed therebetween.

Therefore, the rail device 202 is placed on the bottom surface step portion 401a and fixed to the side step portion 110a with screws, so that the rail device 202 protruding into the storage space can be suppressed, and the overall width of the container 206 can be increased in the vegetable compartment 103. Size, able to reduce dead space.

In addition, since the rail device 202 is assembled by being placed on the bottom surface stepped portion 401a, operability can be improved. In addition, since the portion of the bottom stepped portion 401a is thicker than the bottom wall 401, heat insulation can be ensured.

Furthermore, since the bottom surface step portion 401a is also provided, even if the dew condensation water accumulates in the central portion which is the reference plane of the bottom wall 401, the rail device 202 does not come into contact with the dew condensation water. Therefore, the rail device 202 does not become stuck due to dew condensation water freezing. Thereby, opening and closing of the drawing door 201 can be performed smoothly.

In addition, the drawing door 201 of the vegetable compartment 103 on the lowermost floor is located below the drawing door 201 of the freezing compartment 104 on the upper floor. The position of the drawer door 201 of the vegetable room 103 on the lower floor, in addition to the load of the storage capacity, the external load may also act on this position. Since the anti-falling means 280b of the flange part is integrally formed, the anti-falling means of the rail device 202 of the lowermost drawing door 201 can be held more firmly.

Moreover, the width of the horizontal flange of the rail holding member 280 provided on the vegetable compartment 103 is wider than that of the rail holding member 270 provided on the upper freezer compartment 104, so as the lowermost drawer The anti-falling unit of the rail device 202 of the door 201 can be held more firmly.

In addition, because of the side step portion 110a, the wall thicknesses of the side surfaces of the freezer compartment 104 and the vegetable compartment 103 are all thinner, so a vacuum heat insulating material (not shown) is made to correspond to the part attached to the rail device 202, specifically, By affixing a vacuum heat insulating material having a larger height than between the freezer compartment 104 and the rail device 202 of the vegetable compartment 103 to the outer case 112, heat insulation can be ensured.

As described above, the rail device 202 is fixed by the screws 400 only on the rail holding member 270 and the side wall, but the rail device 202 of the freezer compartment 104 may also be placed on the partition wall 108, and the rail mounting part 223 may be used to fix the rail device 202 with screws. Fixing to the rail holding member 270 can reduce the stress acting on the rail holding member 270 in this case, so that the rail device 202 can be prevented from falling inward.

The rail holding member 280 of the rail device 202 holding the vegetable compartment 103 is also the same, and can also be placed on the corner of the inner box bottom surface formed in the space of the vegetable compartment and fixed with screws, so that the stress acting on the rail holding member 280 can be reduced. Therefore, it is possible to prevent the rail device 202 from falling inward.

In addition, FIG. 12 is a perspective view of the rail holding member 280 . A plurality of holes 290 are formed in the track holding member 280 , and the filled heat insulating material 111 is inserted into the holes 290 and bonded to the inner box 110 , so that the track holding member 280 can be fixed in close contact with the inner box 110 .
