Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a refrigerator equipped with a pull-out door.

BACKGROUND OF THE INVENTION In recent years, it has been proposed to divide refrigerators into compartments to accommodate the items stored therein.

As such a room, for example, Utility Model Publication No. 61-22233
As shown in the publication, the upper door is in the vertical direction.

The structure was such that an inner door and a pull-out door were arranged, and a frame was provided that extended from the pull-out door to the inside of the refrigerator to place a container with an open top surface.

A pull-out door equipped with such a container was used to store vegetables and fruits, with the user bending down to take in and take out the container from above.

Problems to be Solved by the Invention However, although the container is the same size as the width of the refrigerator, if you want to store bottles, cans, or other small items, it is impossible to store bottles, cans, or other small items by simply arranging them in rows and not vertically. Heavy bottles and cans are difficult to remove because you always have to bend down to take them out, and food that you can eat directly (vegetables and fruits) and cans are difficult to remove. Storing the bottles in the same place gave the user a sense of unsanitary hygiene.

In addition, bottles and cans were generally stored in a pocket formed in the door back located on the inside of the inner door. However, the upper and lower ends of the right side of the inner door, etc. were supported by a bottle, and the bottle could be used as an axis to open and close the door, but heavy objects such as bottles and cans were added to the door, causing the door to tilt downward and become attached to the main body. The sealing performance between the inner door and the gasket was poor, resulting in a decrease in cooling capacity.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a refrigerator having a vertically long drawer door for storing bottles and cans on the upper and lower sides.

Means for Solving the Problems A refrigerator having a pull-out door according to the present invention includes a storage chamber formed vertically, a fixed rail provided on opposite side walls of the storage chamber, and a refrigerator supported by the fixed rail. A pull-out door equipped with a movable rail, support pieces provided above and below that support a tray for receiving articles extending from the pull-out door toward the storage room, and a lower support piece on the back side of the support piece. a back plate having an upper end positioned above the upper support piece; a cold air discharge port opening above the upper end of the back plate at the back of the storage chamber and causing a portion of cold air to come into contact with the back plate; The structure includes a cold air passage extending vertically between the back plate and the inner surface of the storage chamber and reaching the bottom of the lower tray, and an opening formed in the back plate between the upper and lower trays.

Effects of the present invention With the above-described configuration, items such as bottles, cans, and small items can be stored in each tray, and a portion of the cold air from the cold air outlet hits the back plate, creating a cold air path extending vertically. It is guided downward into the storage chamber along this line, and is also guided to the upper surface of the saucer below the opening. Further, other cold air is guided to the upper surface of the upper tray and is reliably cooled. Furthermore, since the back plate is located above the back of the upper and lower saucers, if you pull out the door and place the bottle on the back of the saucer to store it, then suddenly pull out the door and the bottle will be placed in the saucer. A sudden acceleration is applied to the bottom of the bottle, which causes the bottle to try to topple over, but it hits the back plate and does not fall back.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 3.

Reference numeral 1 denotes a refrigerator body, which is composed of an outer box 2, an inner box 3, and a foamed heat insulating material 4 filled between the two boxes. The refrigerator has six storage compartments (other than the vertical storage compartment 6 with a wooden plan are not shown), and a partial compartment door 6 on the upper left side. Freezer compartment door from upper right to lower 7. Refrigerator door 8. A vegetable compartment door 9 is disposed, and a vertically elongated pull-out door 10 is disposed astride the refrigerator compartment door 8 and the vegetable compartment door 9. This drawer door 10 is provided for opening and closing the vertically long storage chamber 6.

Reference numeral 11 denotes a cooling chamber formed within the upper wall 12 of the vertically elongated storage chamber 6, in which a cooler 1a and a blower 14 are provided. The vertically elongated door 1o is attached to a movable rail 17 on which rollers 16 are attached to fixed rails/L/15 having a substantially U-shaped cross section and extending in the depth direction below the opposite side walls sa and sb of the storage room 50. is installed. Reference numeral 18 denotes a tray for placing the bottle 19, which has a flange 20 around its periphery, and is supported by placing the flange 2° on a support piece 21 extending from the door 10 to the back of the storage room 6. This support piece 21 is attached above and below the door 1°, and the movable rail 17 also serves as the lower part.

Reference numeral 22 denotes a back plate which supports the support piece 21. Movable Ray/I/17 (
When referring to the support piece 21 below, the non-special support piece 2
It is attached vertically on the back surface of the (treated as 1). The upper end of this back plate 22 is configured so as not to extend to the top surface 6c of the storage chamber 6.

23 is a cold air discharge port, which communicates with the cooling chamber 11, and
It is located above the back surface 5d of the storage room 5.

A portion of the cold air discharged from the discharge port 23 comes into contact with the upper part of the back plate 22, and the other portion continues to flow straight. Further, a cold air intake port 24 into the cooling chamber 11 is formed in the top surface 6c of the storage chamber 6. Reference numeral 26 denotes a cold air air path which extends from the discharge port 23 to the bottom of the lower tray 18, and is formed in a space formed by bending the end surface of the back plate 22 and the back surface 6d of the storage chamber 6. It is something that

Reference numeral 26 denotes an opening formed in the back plate 22 between the upper tray 18 and the lower tray 18, through which cold air flows from the cold air passage 26. It is preferable that the saucer 18 be provided with a large number of small holes to prevent convection of cold air.

Therefore, since items such as bottles and cans are stored in each tray 18, they can be arranged and stored vertically, so the user can take out the items without bending over, and it is hygienic because there is no need to store them together with vegetables. There is also. Furthermore, since heavy items such as bottles and cans can be supported by the rails 15 and 17, the door will not lower due to the weight and the sealing performance will not deteriorate.

Furthermore, the cold air hits the upper end of the back plate 22 and is divided, and is also introduced between the upper and lower trays 18 through the opening 26, so there is no possibility of non-uniformity in temperature between the upper and lower trays 18. Furthermore, when a bottle is stored in the tray and suddenly opened to take it out, the bottle tries to fall backwards, but it hits the back plate and is prevented from falling, causing items to fall to the bottom of the storage compartment and prevent the drawer group from falling. It never gets boring.

Effects of the Invention As is clear from the above embodiments, the refrigerator having a pull-out group according to the present invention can separate the stored items by providing vertical storage trays with vertically arranged trays. Cans and other items can be separated to make them more sanitary, and heavy items can be taken out without having to bend over. In addition, the cold air is divided at the upper end of the back plate and guided upward and downward into the storage chamber, and is also introduced between the upper and lower trays through the opening, so that uniform cooling can be achieved. In addition, since the back plate prevents items from falling, falling items will not interfere with the opening and closing of the pull-out group, allowing smooth opening and closing.
