There are also shelves, drawers, trays, etc. designed according to the shape of the food in each refrigerator and freezer.

The temperature of different positions in the refrigerator compartment and the freezer compartment is also different, and this is because the shelves, drawers, trays, etc. in each space regulate the convection of the cold air in the box body 1, so that the temperature in each position changes. Usually, the lower the refrigerator body 1 is, the less cold air is transmitted, and the temperature is higher.

The bucket-type box door at the lower part of the refrigerator box 1 can be pulled out/pushed in to form a drawer room 20 for storing food. The drawer room 20 is mainly used as a freezer room for storing meat, seafood and other foods that need to be preserved for a long time. . Moreover, the drawer room is also divided into many storage spaces of different sizes to ensure that no matter how large the food volume is, it can be properly preserved.

A storage box 30 for storing food with a relatively large volume and a drawer for storing food with a smaller volume than the food stored in the storage box 30 are provided in the drawer chamber 20 . The food in the storage box can be preserved regardless of its size and type.

The storage box 30 is connected with the bottom of the bucket-type box door 12 by a hinge, and when the bucket-type box door 12 is pulled out forward, the storage box is pulled out together with the bucket-type box door 12 . Therefore, the user can see the inside of the storage box 30 only by pulling out the dump box door 12 , and can pull out/push the storage box 30 without other operations.

The upper ends on both sides of the storage box 30 are fixed on one side of the three-section guide rail 50 , and the other side of the guide rail 50 is fixed on both sides of the box body 1 . Therefore, the storage box 30 is guided by the guide rail 50 when being pulled out/pushed together with the dump box door 12 .

In addition, the upper end of the storage box 30 is provided with a pull-out drawer 40, and the pull-out drawer 40 is composed of many metal wires and a sealing surface.

But, there is following problem in the pull-out drawer of the refrigerator of above structure: the front and rear movement of pull-out drawer 40 relies on the guiding guide rail (not shown in the figure) of side to guide, and when pull-out drawer 40 is closed, the upper end of pull-out drawer 40 will meet with The front of the refrigerator collided. There is a problem of making noise or pulling out the drawer 40 when colliding.

As shown in FIG. 2 , the refrigerator box 100 of the present invention is composed of a refrigerator compartment 200 and a drawer compartment 300 .

The refrigerating chamber 200 is located on the top of the casing 100 and is divided into left and right parts. There are various shelves, drawers and trays to separate the refrigerating chamber 200 for convenient food storage.

The flow of cold air sent from one side of the box body 100 is affected by the existence of shelves, drawers, and trays, thereby realizing the restriction or adjustment of cold air convection, causing differences in the temperature distribution in the refrigerator, and users can choose the most suitable food according to the temperature storage space.

The door of the refrigerator compartment 200 is a revolving door located on the left and right sides of the refrigerator cabinet 100 . The revolving box door is connected with the upper ends on both sides of the box body 100 through hinges, and can be opened outwards.

The left and right rotary doors 220 divide the refrigerating room 200 into two independent spaces, and an independent room of the refrigerating room 200 can be used as a freezing room when needed.

There is a door handle 222 on one side of the revolving box door 220 , and the user can open and close the revolving box door 220 capacitively through the door handle. And the home bar etc. that are convenient to take water or drink are also set on the revolving box door 220 .

There is also a drawer chamber 300 below the freezer chamber 200 of the casing 100 . The drawer compartment 300 can be pulled out or pushed forward like a drawer, and is mainly used as a freezer compartment. The drawer chamber 300 can freeze food that needs to be preserved for a long time, such as meat or seafood. As a freezer, it has a separate cold air supply port, which has a very strong cooling capacity.

The drawer room 300 can be used not only as a freezing room, but also as a refrigerating room when necessary. The space of the freezer is relatively large. When used as a freezer, it can store fruits and vegetables that are difficult to hold in containers, and can also store some bulky and heavy foods.

The drawer type box door 320 is arranged in the front of the drawer chamber 300 . The lower end of the drawer-type box door is connected with the food storage box 340 through hinges, and the storage box 340 is equipped with a 3-section guide rail 360 that can slide back and forth and stretch in multiple sections.

One side of the 3-section guide rail 360 is fixed on two walls inside the drawer chamber 300 , and the storage box 340 can slide back and forth along the 3-section guide rail 360 . There is a handle above the drawer-type box door, and the storage box 340 and the drawer-type box door 320 can be drawn/pushed in by pulling or pushing the handle.

The upper part of the drawer chamber 300 is divided into left and right sides. The left side is an ice maker that can automatically make ice and store it. Food stored separately.

As shown in FIGS. 3 and 4 , the double drawer 400 is composed of a guide rail 420 , an auxiliary drawer 440 , and a main drawer 460 . The guide rail may guide the pull-out/push-in of the sub-drawer 440, and is installed inside the refrigerator.

The side surface of the guide rail 420 is a rolling guide portion 422 . The rolling guide part 422 is used to guide the first rolling guide attachment 442 and the sliding guide part 444 , is located on one side of the guide rail 420 , and protrudes laterally. That is, a "U" (viewed from the side) shape that opens forward is formed, and the first rolling attachment 442 is used to perform rolling motion on the rolling guide part 422 .

A hanging groove 424 is formed at a front end of the rolling guide portion 422 . As shown in the figure, an upwardly protruding hanging groove 424 is formed at the front end of the bottom surface of the rolling guide portion 422 , and the hook formed on the sliding guiding portion 444 is hung on the hanging groove 424 .

The refrigerator has a pair of guide rails 420 installed on the inner side of the refrigerator box 100 , specifically installed on the left and right side walls of the drawer chamber 300 corresponding to each other. Therefore, the rolling guide portion 422 formed by a pair of guide rails 420 should be installed oppositely.

The auxiliary drawer 440 is installed on the guide rail 420, and the front, top, and rear parts of the auxiliary drawer 440 are in the shape of an open square box.

There are first rolling attachments 442 at the rear ends of both sides of the auxiliary drawer 440 . The first rolling attachment 442 is in contact with the rolling guide part 422 to perform rolling motion. If the first rolling attachment 442 rolls in the rolling guide portion 422 of the guide rail 420 , the auxiliary drawer 440 moves forward and backward along the guide rail 420 .

The first rolling attachment 442 is an attachment to ensure the smooth movement of sliding devices such as rollers or bearings. If a roller is formed, it can be made of the same material as the auxiliary drawer 440 .

Both sides of the first rolling attachment 442 are provided with sliding guides 444 front and rear. The sliding guides 444 and the first rolling attachment 442 are mounted on the rolling guides 422 of the guide rail 420 to guide the auxiliary drawer to slide back and forth. Such a structure can prevent the front end of the auxiliary drawer 440 from drooping when the auxiliary drawer 440 is pulled forward along the guide rail 420 . Therefore, it is preferable that the sliding guide part 444 can correspond to the shape of the rolling guide part 422 .

The sliding guide part 444 extends from the place where the first rolling attachment 442 is installed to the front end of the auxiliary drawer 440, and the middle part forms a hook 446 as shown in the figure.

The hook 446 is engaged with the hanging groove 424 to prevent the auxiliary drawer 440 from being pulled forward too long, and its shape is corresponding to the hanging groove and protrudes downward.

The front end of the sub-drawer 440 has a cushioning material 448 . In detail, the cushioning material 448 is installed at the front end 440b of the side of the sub-drawer 440 . The buffer material 448 can buffer the impact force when the main drawer 460 collides with the auxiliary drawer 440 , and is made of elastic materials such as rubber.

Pull-out guide rails 450 are installed on both sides of the auxiliary drawer 440 , and the pull-out guide rails 450 can guide the main drawer to slide back and forth. The second rolling attachment 462 is installed on the pull-out guide rails 450 .

The position of the pull-out guide rail 450 is preferably lower than the sliding guide part 444 , and is recessed from the inside to the outside of the auxiliary drawer 440 . And the pull-out guide rail 450 extends from the inner rear end of the auxiliary drawer 440 to the central portion of the auxiliary drawer 440 .

A fixing part 452 is installed at the front end and the rear end of the pull-out guide rail 450 . The fixing part 452 is recessed downward, and the second rolling attachment 462 is installed and fixed on the fixing part 452 at the same time.

Viewed from the side, the other end of the pull-out guide rail 450, that is, the rear end of the auxiliary drawer 440 is folded upward at a right angle, and extends upward, and one end of the extension is open. Therefore, the second rolling part 462 installed on the main drawer 460 can be inserted downward from the upper side of the rear side of the sub-drawer 440 .

And the rear 440c of the auxiliary drawer 440 is equivalent to half of its upper part into an open shape, which ensures that the main drawer 460 can be easily inserted into the pull-out guide rail 450, and is not affected by the guide rail 420 by virtue of the pull-out guide rail 450.

The main drawer 460 is installed in the auxiliary drawer 440, and the main drawer 460 is used as a space for storing food, in the shape of a box with an upper opening, and a space 460' for storing food is formed inside. In order to ensure that the main drawer 460 can be completely inserted into the auxiliary drawer 440 , the main drawer 460 should be smaller than the auxiliary drawer 440 .

The periphery of the upper end of the main drawer 460 is vertically bent to the outside, and a front bezel 464 is arranged on the front to become a part of the front appearance. The front baffle 464 can not only prevent the food stored inside from pouring out, but also can be used as a handle when the user pulls out the main drawer 460 .

The two sides of the main drawer 460 have the second rolling attachment 462 with the same shape as the first rolling attachment. The second rolling attachment 462 is used by the pull-out guide rail 450, and is in contact with one side of the pull-out guide rail 450 to roll back and forth to ensure that the main drawer 460 can be pulled out from the inside of the secondary drawer 440 .

The second rolling attachment 462 is located at a slightly central portion of the rear of both sides of the main drawer 460 , that is, at a position corresponding to the position where the guide rail 450 is pulled out. In other words, when the second rolling accessory 462 is installed on the main drawer 460 on the auxiliary drawer 440, it should ensure that the second rolling accessory can be used naturally when the guide rail 450 is pulled out.

The 2nd rolling accessory 462 is the accessory that guarantees the sliding device such as roller or bearing to move smoothly like the 1st rolling accessory 442, if form roller then can use same material as main drawer 460 to make.

There is a cold air inlet 466 at the back of the main drawer 460 to ensure that the cold air supplied from the back can flow into the main drawer 460 smoothly.

The effect of the double drawer of refrigerator of the present invention is described below:

As shown in FIG. 4 and FIG. 5 , when the main drawer 460 overlaps with the auxiliary drawer 440 , pulling the front panel 464 forward by hand will pull the main drawer 460 out of the auxiliary drawer 440 . At this time, the second rolling attachment 462 rolls from the rear end of the pull-out guide rail 450 to the front end.

While the main drawer 460 is moving forward, the auxiliary drawer 440 will also be pulled out sequentially by means of the guide rails 420 , and the fully drawn state of the main drawer 460 and the auxiliary drawer 440 is shown in FIG. 6 .

After the main drawer 460 and the auxiliary drawer 440 are pulled forward, the user can take or store food in the accommodation space 460' of the main drawer 460. Then push back the front bezel 464 to slowly push the main drawer into the refrigerator. At this time, the main drawer 460 and the auxiliary drawer 440 move backward in sequence, and the final result is shown in FIG. 5 .

The buffer material 448 buffers the collision between the main drawer 460 and the auxiliary drawer 440, that is, when the main drawer 460 moves backward, if the speed is too fast, it will collide with the auxiliary drawer 440, and at this time the rear end of the main drawer 460 will hit the installation. With the buffer material 448 on the side 440b of the auxiliary drawer 440, the impact force generated during collision will be greatly reduced.

Through the above description, relevant workers can make various changes and modifications without departing from the scope of the technical idea of the present invention.

For example: in the embodiment, we use rubber as the raw material of the cushioning material 448, but as the raw material of the cushioning material 448, other materials that can relieve impact force can also be used.

The position of the cushioning material can be changed, it can be at the front end of the lower side 440a of the auxiliary drawer 440 or at the position where the rear end of the main drawer 460 contacts the front end of the auxiliary drawer.

In addition, the cushioning material 448 can be installed on the front end of the side 440b of the auxiliary drawer 440 in the form of a strip as in the embodiment, can also be installed on the upper end of the side 440b of the auxiliary drawer 440, or can be divided into several pieces and installed on the side 440b of the auxiliary drawer 440 top, bottom or middle.

Therefore, the technical scope of the present invention is not limited to the above-mentioned embodiments, and the technical scope must be determined according to the claims.
