BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a freezer / refrigerator with a thawing device, and more particularly to a duct structure for cleaning the inside of a duct.

[0002]

2. Description of the Related Art Conventionally, as a freezer / refrigerator with a thawing device,
There is a system in which ducts are provided on both sides of a freezing / refrigerating room, and cold air or warm air is circulated from one side portion to the other side for freezing / refrigerating or thawing. FIG. 2 is a schematic cross-sectional view of the freezer / refrigerator with a defroster having such a configuration as seen from the front.

In the figure, 1 is an outer box surrounded by a heat insulating material, 2 is a partition plate provided at a distance from the inner surfaces of both sides of the outer box 1, and 3 is an inner surface of the upper part of the outer box 1. Top plate provided with a space between the partition plate 2 and the top plate 3 is frozen.
It constitutes the refrigerator compartment 4. The outer box 1 and each of the partition plates 2 and the top plate 3 form a duct 5A on one side, a duct 5B on the other side, and an upper duct 5C, and a large number of ventilation holes 6 are arranged on each partition plate 2. I have set up. An evaporator 7 and a blower 8 are installed in the upper duct 5C, and a machine room 9 is provided below the outer box 1, and a condenser 10 and the like are installed in the machine room 9, which are cooling devices. Is doing. A warming / humidifying device 11 is installed in the machine room 9, and a steam nozzle 12 connected to the warming / humidifying device 11 is provided in the duct 5B on the other side.
Is equipped with. The heating and humidifier 11 and the steam nozzle 12 described above.
Is the defroster. Reference numeral 13 is a tray on which an object to be cooled such as food is placed, 14 is a rail for guiding the tray 13, and 15 is a shelf for mounting the rail 14.

During cooling of this freezer / refrigerator, the above cooling device is operated, the cooled refrigerant is circulated to the evaporator 7 for heat exchange, and cool air is blown by the blower 8 in the direction of the arrow in the figure. The cold air is circulated through the ventilation port 6 and through the freezing / refrigerating chamber 4, and the food or the like in the tray 13 is cooled. Further, at the time of thawing, the warming / humidifying device 11 is operated without circulating the refrigerant, the heated steam is ejected from the steam nozzle 12, and the steam is similarly circulated by the blower 8 to thaw the food or the like.

A drainage port 17 is provided on the floor 16 of the freezing / refrigerating compartment 4 so that liquid produced when it is thawed can be discharged from the drainage port 1.
It is discharged from the outside. Since dirt is accumulated on the floor 16 of the freezing / refrigerating compartment 4 and the bottoms of the ducts 5A and 5B on both sides during repeated thawing, the floor 16C is usually sprayed with a hose or the like for cleaning.

[0006]

However, in the above cleaning work, the floor 16 in the freezing / refrigerating compartment 4 can be satisfactorily cleaned, but the cleaning around the bottoms of the ducts 5A and 5B is not perfect. It was Therefore, in order to sufficiently perform this, it is necessary to remove the tray 13, further remove the shelf posts 15 and the partition plate 2 and the like, and then remove the bottom parts to clean the bottom part. Installation work was troublesome.

An object of the present invention is to provide a freezer / refrigerator with a thawing device, which is capable of easily cleaning around the bottoms of the ducts 5A and 5B with a simple operation.

[0008]

In order to solve the above-mentioned problems, the present invention has partition plates on both sides of a freezing / refrigerating room, and a duct is formed outside the partition plates, and each partition plate has a duct. A large number of ventilation openings are provided, and cold air or warm air is circulated from one duct through the freezing / refrigerating room to the other duct for freezing.
In a freezer / refrigerator with a thawing device for refrigerating or thawing,
The partition plate has an opening for cleaning which is opened from the floor surface of the freezing / refrigerating room to an appropriate height, and is attached to the upper part of the opening by a hinge so that the hinge serves as a rotation center. A door is provided so that the opening can be opened and closed by rotating the door.

[0009]

According to the present invention, when the opening is closed by the door, the freezing / refrigerating room is in a normal usable state. When the door is rotated toward the freezing / refrigerating room with the hinge as the center of rotation, the opening is opened and cleaning around the bottom of the duct becomes possible.

[0010]

1 is a perspective sectional view showing a freezer / refrigerator with a thawing device according to the present invention. In the figure, parts equivalent to those in FIG. 2 are designated by the same reference numerals, and different parts will be described below.

Reference numeral 18 denotes a partition mounting metal fitting, one end side of which is fixed to both sides of the outer box 1 by screwing, and the other end side of which is mounted by jointly tightening the partition plate 2A or 2B and the shelf 15 with screws. There is. Between the outer box 1 and the partition plates 2A and 2B, the duct 5 on one side due to the height of the partition mounting bracket 18 is provided.
A (not shown) and the duct 5B on the other side are formed.
A rail mounting hole 19 is provided in the shelf 15, and a hook (not shown) provided at the upper end of the rail 14 is hooked in the rail mounting hole 19 for mounting.

Reference numerals 20A and 20B are openings for cleaning, and the widths of the ducts 5A and 5 are provided at the lower end portions of the partition plates 2A and 2B.
B is made to substantially coincide with the floor B and is cut out at an appropriate height from the surface of the floor 16 so that a cleaning tool such as a hose can be inserted through the openings 20A and 20B.

Reference numeral 21 denotes a cleaning door, the upper end of which is attached to the upper ends of the openings 20A and 20B by a hinge 22, and the hinge 22 is rotated about the hinge 22 to the freezing / refrigerating chamber 4 side. The openings 20A and 20B can be opened and closed. Reference numeral 23 is a spring for urging the door 21 toward the closing side, 24 is a stopper for locking the door 21 in the closed state, and 25 is a handle for opening and closing the door 21. The door 21 is provided with a ventilation port 6 as in the partition plates 2A and 2B.

In the above structure, when cleaning the bottoms of the ducts 5A and 5B, the tray 13 and the rail 14 extending over the door 21 are removed, and the door 21 is opened by hand. -Use a cleaning tool such as a cleaning tool for the openings 20A and 20B.
Insert it into the ducts 5A and 5B, and then discharge the water to wash it away.
When cleaning is completed, the door 21 opens when the hand is released.
Block A and 20B. When the rail 14 and the tray 13 are attached, the freezing / refrigerating chamber 4 is in a normal usable state.

[0015]

As described above, according to the present invention, an opening for cleaning is provided in the lower part of the partition plate on the side of the freezing / refrigerating room forming the duct, and a door that can be opened and closed is provided in the opening. Since the above is attached, it is possible to remove the parts in the freezing / refrigerating chamber and clean the parts around the bottom of the duct through the opening with a minimum of installation, and the cleaning work is facilitated.
