Description

[Detailed description of the invention] The present invention relates to a refrigerator-freezer that cools the freezer compartment and the refrigerator compartment by using a blower to supply air cooled by a cooler provided in a cooling compartment formed within a partition wall. In the case where the lower part of the freezing chamber is equipped with a special chamber for freezing food faster and an ice-making chamber with shelves for placing ice-making trays, The object of this invention is to independently form blow-off ports for supplying cold air to the freezer compartment, and to arbitrarily change the amount of air blown from the blow-off ports using a single damper device.

Conventionally, this type of refrigerator-freezer does not have a means to adjust the amount of cold air that is blown into the dedicated compartment, the ice-making compartment, and other parts of the freezer compartment. This has disadvantages such as the fact that the ice is blown out into the ice making chamber, wasting the refrigeration capacity, and it is not possible to increase the amount of air blown into the dedicated chamber even when it is desired to rapidly freeze food, for example. .

The present invention was developed in view of the above-mentioned drawbacks, and provides a structure in which cold air supplied to the freezer compartment is effectively blown away using a single damper device.

Embodiments of the present invention will be described in detail below with reference to the drawings. Reference numeral 1 denotes a refrigerator body, and the inside of the refrigerator is divided by a partition wall 2 into a freezing compartment 3 that is cooled to freezing temperature and a refrigerator compartment 4 that is maintained above freezing temperature. A cooler 7 included in the cooling cycle is installed in a cooling chamber 6 formed in a space between the partition wall 2 and a bottom plate 5 of the freezing chamber provided slightly above the partition wall 2. The air cooled by the cooler 7 is sent to the freezer compartment 3 by the blower 8.
It is sent to the refrigerator compartment 4 through the duct 9 and to the refrigerator compartment 4 through the duct 10, thereby cooling both compartments. 11 is a damper thermo that senses the temperature inside the refrigerator compartment 4 and automatically adjusts the amount of cold air blown into the refrigerator compartment 4.

On the bottom plate 5 of the freezer compartment 3 are a dedicated compartment 12 and an ice making compartment 1.
A duct member 15 forming a duct 9 is fitted into a stepped portion at the rear of the box 14, as shown in the exploded view of FIG. The duct member 15, the freezing chamber bottom plate 5, and the compartment box body 14 form the constituent walls of the dedicated chamber 12 and the ice making chamber 13, respectively. A freezer compartment outlet 16, a dedicated compartment outlet 17, and an icemaker compartment outlet 18 are independently formed on the upper surface of the duct member 15 and at positions corresponding to the ice making section 13a of the dedicated chamber 12 and ice making compartment 13, respectively. Freezer compartment outlet 16 of compartment box body 14
A slit 19 is formed at a position corresponding to the slit 19, and a door body 20 is provided in front of the private chamber 12, for example, with its upper portion rotatably supported and capable of opening and closing. An ice making tray 21 is placed in the ice making section 13a of the ice making chamber 13, which has an open front, and an ice stocker 22 is housed in the ice storage section 13b at the bottom. With this configuration, cold air circulates from each outlet as shown by the arrow in the figure, thereby cooling each chamber.

Reference numeral 23 denotes a damper plate having a horizontal piece 24 and a vertical piece 25, and an operating knob 26 that protrudes forward and is bent upward into a substantially L-shape.
The upper part of the duct member 15 has a horizontally long engagement hole 2.
7, and a horizontally elongated knob hole 28 is drilled at a suitable position in the compartment box body 14, and a knob part 26 is inserted into the engagement hole 27 from the back of the duct member 15, and the root part is slid laterally. After the gripping portion 26 is freely engaged, the upper end portion of the gripping portion 26 is caused to protrude upward from the gripping hole 28. This knob portion 26, the engagement hole 27, and the knob hole 28
The positions are determined in advance so that they are in a lateral sliding relationship. In this way, the damper plate 23 is slidably provided above the duct 9. Also, horizontal piece 24
is provided corresponding to the freezer compartment outlet 16, and the vertical piece 25 is provided corresponding to the ice making compartment outlet 18. When the damper plate 23 is fully slid toward the ice making compartment 13 side, the vertical piece 25
completely closes the ice-making compartment outlet 18, and the horizontal piece 24 limits the opening area of the freezer compartment outlet 16, and also closes the dedicated compartment 12.
When it is slid to the side, the ice-making compartment outlet 18 and the freezer compartment outlet 16 are fully opened.

With the above configuration, when you want to freeze the water in the ice tray 21 in the ice maker 13, move the knob 26 of the damper plate 23 and slide the damper plate 23 toward the dedicated chamber 12, and the ice maker outlet 18 will open. When fully opened, cold air is sufficiently blown onto the ice making tray 21, and ice is made quickly. Next, when there is no time constraint for ice making, that is, when there is no need for rapid ice making,
If you want to quickly freeze food, etc., move the knob 26 all the way to the ice making compartment 13 side, the ice making compartment outlet 18 will be fully closed, and the opening area of the freezing compartment outlet 16 will also be limited. Therefore, most of the cold air that has been blown out from both air outlets until now is concentrated on the dedicated room air outlet 17, and a large amount of cold air flows out from the dedicated room air outlet 17, rapidly freezing the food, etc. in the dedicated room 12. .

Here, the freezer compartment outlet 16 is an opening for ensuring an amount of cold air sufficient to cool the inside of the freezer compartment 3 including the ice making compartment 13 to at least a temperature suitable for frozen storage even when the ice making compartment outlet 18 is fully closed. Make sure to leave some area.

By constructing this device as described above, cold air is blown directly into the dedicated compartment, ice-making compartment, and the freezer compartment other than the two compartments, resulting in a good cooling effect, and the cold air can be effectively distributed to each compartment, achieving quick ice making and quick freezing. In addition, the above-mentioned cold air is blown by a single damper device, so the operation is simple, the structure is simple, and the assembly workability is excellent.
