Abstract

PROBLEM TO BE SOLVED: To provide a refrigerator which achieves improvements in the temperature controlling performance when controlling the supply of cooled air to two storage chambers with two baffles. SOLUTION: A baffle for an ice temperature chamber is provided to control the supply of cooled air to an ice temperature chamber 10, a baffle for a cold storage compartment to control the supply of cooled air to a cold storage compartment 11 and a damper device 46 comprising a damper motor is provided to drive the baffles. The damper motor is controlled based on temperatures of the ice temperature chamber 10 and the cold storage compartment 11. The damper device 46 is so arranged to allow the opening or closing of the baffle for the ice temperature chamber alone with the baffle for the cold storage compartment closed while the baffle for the ice temperature chamber is opened or closed to open the baffle for the cold storage compartment alone.

Description

DETAILED DESCRIPTION OF THE INVENTION [0001] BACKGROUND OF THE INVENTION 1. Field of the Invention
First storage room formed and temperature higher than this first storage room
And a second storage room with high
Cool air is supplied to each storage room by a blower, and
Control by controlling the supply of cold air to each room
It is about the warehouse. [0002] 2. Description of the Related Art Conventionally, this kind of refrigerator has been
No. 6-12301 (F25D23 / 00).
As shown in FIG.
When the refrigerator room (+ 3 ° C to + 5 ° C) is constructed
In each case, cool air from a cooler is distributed and supplied to each room by a blower
By cooling it. Also, in the refrigerator compartment or
In the area separated from it, ice colder than the cold room
Greenhouses (about 0 ° C to -3 ° C) etc.
Is being developed. In this case, control of the compressor and the blower is usually
It is based on the temperature of the freezer,
The temperature of the room is set to the specified freezing temperature.
Controls are provided with ducts to supply cool air to each room.
The opening and closing of the damper device is performed by the baffle
You. Conventionally, gas has been sealed in this damper device.
A so-called gas seal that opens and closes the baffle with the bellows inserted
In-situ dampers were used, but in recent years,
In order to improve the temperature control performance of the greenhouse,
Based on the output of each detected temperature sensor, the motor
The opening and closing of each baffle by a drive device such as
Has been issued. Further, as this damper device, a single model
Control the supply of cold air to the refrigerator compartment and the ice greenhouse
One that drives two baffles is the mainstream. this
In this case, the output of the motor is
Transmitted, both baffles closed (closed / closed), one side
Only open (open / closed), both open (open / closed)
Open) and open only the other (closed / open).
It comes out. According to this configuration, each baffle is driven.
The need to provide separate motors
There are points. [0007] However, this is not the case.
Such a damper device rotates the motor in one direction or
In order to create the above four states cyclically by turning and reversing,
One baffle can be opened and closed independently while the other baffle
You must open and close one baffle to open
You may have to do it. If so, one baffle
When the temperature of the refrigerator is controlled, the baffle of the ice greenhouse is activated.
Each time you make it, the baffle in the refrigerator compartment opens and closes unnecessarily
Therefore, there is a problem that the refrigerator compartment is overcooled. The present invention solves such a conventional technical problem.
Two baffles.
Controllability in controlling the supply of cold air to storage rooms
It is intended to provide a refrigerator with improved performance. [0009] The refrigerator according to the present invention has a heat insulating structure.
The first storage compartment defined in the box and this first storage
And a second storage room having a higher temperature than the room.
Cooled air is supplied to each storage room by a blower.
The first and second bafflesGear
Single damper to open and close both baffles via
A damper device consisting of a motor and the temperature of each storage room

The inside of the container 19A in 0 is set to the H volume of the setting circuit 113.
Of the temperature of the ice greenhouse 10 set at 0 ° C.
Maintain an ice temperature range of about -3 ° C. In this case, the baffle 43 is opened as described above.
At that time, the baffle 44 is always opened and closed. That
Therefore, the supply of cold air to the refrigerator compartment 11 is controlled by the baffle 44
Then, the baffle 43 controls the supply of cold air to the ice greenhouse 10.
With such a configuration, cooling of the refrigerator compartment 11 is required.
Even if there is no
The door opens and closes, and cool air flows into the refrigerator compartment 11. In such a state, the supercooling of the refrigerator compartment 11 occurs.
However, in the present invention, the baffle 43 is used for a refrigerator,
The ice greenhouse 10 is used for an ice greenhouse.
Since the temperature is lower than that, there is no fear of such supercooling. On the other hand, the suction port 61 after the refrigerating chamber is

It will flow into the duct 63. Here, as described above, the left refrigerator compartment suction duct is used.
The passage length of the gate 77 is the passage length of the refrigerator compartment suction duct 78 on the right side.
It is longer than. Therefore, the same passage cross-sectional area and
In the suction area, the flow path resistance of the refrigerator compartment suction duct 77 is refrigerated.
Because it becomes larger than the flow path resistance of the chamber suction duct 78, it is refrigerated.
The amount of cool air sucked from the front suction port 79 is equal to the cold storage front suction port.
It is smaller than the amount of cold air sucked from 81. [0069] The amount of cold air sucked in this way is the
If it is different on the right, the cooling effect of the front part in the refrigerator compartment 11
It is biased, and in the embodiment, the left is not cooler than the right
However, as described above, the passage of the refrigerator compartment suction duct 77 on the left side
The cross-sectional area of the road is determined by the cross-sectional area of the right refrigerator compartment suction duct 78.
The suction portion 77A is also wider than the suction portion 78A.
The ducts 77 and 78 have a flow path resistance.
The resistance is almost uniform. Therefore, the suction port in front of the refrigerator compartment
The amount of cold air flowing into the cooling chambers 79 and 81 is substantially uniform,
The inside can be cooled uniformly. Next, the cool air flowing into the return duct 63
