FIG. 1 is a schematic cross-sectional view showing an attached state of a temperature controller for a refrigerating room (for a chilled room) of a ventilation device of a refrigerator of the present invention. In the figure, (1) to (12) and (14) are the same or corresponding constituent parts as those of the conventional example.

In the figure, (15) is a duct for a refrigerator compartment in the control box formed in the control box (10), and (16) is a duct for a chilled chamber in the control box also formed in the control box (10). These ducts are juxtaposed inside the control box (10), and the duct for the chilled chamber (1
An air outlet (16a) is formed at the lower end of 6). (1
7) is a heat insulating material, which insulates the refrigerating compartment duct (15) in the control box and the chilled compartment duct (16) in the control box from the refrigerating compartment (3).
(18) is a control box (1
It is a cover of the surface part of 0).

The control box (10) of this embodiment is formed over the entire height of the rear part of the refrigerator compartment (3), and the control box (10) has a plurality of outlets (10).
a), (10b), and (10c) are appropriately arranged. Also,
The installation method of the refrigerating room temperature controller (11) and the chilled room temperature controller (12) is opposite to the conventional installation method. That is, the temperature controller bodies (11a) and (12a) and the refrigerating room baffle (11b) and the chilled room baffle (12b) are installed upside down.

The ventilation device of the refrigerator according to this embodiment is configured as described above, and cool air generated in the cooling unit (6) is blown to each room in the refrigerator body (1) by the fan (8) to thereby open each room. The basic operation for making each temperature suitable is the same as the above-mentioned conventional example. Therefore, here, especially, the cooling operation of each chamber will be described focusing on the improved points.

First, in the cooling of the refrigerating compartment (3), the cool air is forcibly sent to the rear duct (9) by the action of the fan (8), and this cool air passes through the air outlet (9c) of the refrigerating compartment duct (9a). A plurality of outlets (10a), (10b) of the control box (10) formed over the entire height of the rear part of the refrigerating room (3),
It is performed by blowing from (10c) into the refrigerating compartment (3). As described above, in the ventilation device for the refrigerator of this embodiment, the cool air from the cooling unit (6) is supplied to the plurality of outlets (10).
Since the air is blown from a), (10b), and (10c) all at once, the inside of the refrigerator compartment (3) can be cooled in a short time. Moreover,
The outlets (10a), (10b), (10c) are, for example,
By appropriately arranging the shelves provided in the refrigerating compartment (3) according to the height of the shelves, the temperature distribution inside the refrigerating compartment (3) can be made uniform even in the refrigerating compartment (3) having a relatively large volume. . Therefore, the cooling in the refrigerating chamber (3) is performed by the conventional air outlet (10
Compared with a) the ventilation device of the refrigerator in one place, a) can be performed very efficiently.

And when the inside of the refrigerator compartment (3) reaches a predetermined temperature,
The temperature controller body (11a) of the refrigerating compartment temperature controller (11) senses this temperature and closes the blowout port (9c) of the refrigerating compartment duct (9a) with the refrigerating compartment baffle (11b). . In this embodiment, the refrigerating compartment temperature controller (11) is also installed such that the temperature controller bodies (11a) and (12a) are located at positions other than the downward direction of the air outlet (9c) of the rear duct (9). Since it is installed like this, if you forget to close the door of the refrigerator body (1),
Even if water drops adhere to the inside of the rear duct (9) and drop out from the outlet (9c), they do not directly reach the temperature controller bodies (11a) and (12a). Therefore, as in the conventional case, it is possible to eliminate the cause of the malfunction, which is caused by water droplets splashing on the temperature controller bodies (11a) and (12a) being frozen again. Therefore, as compared with the conventional refrigerating room temperature controller (11), reliable operation can be ensured, and reliability is extremely improved.

Further, as shown in FIG. 4, if the blowout port portion (9c) of the refrigerating compartment duct (9a) is formed to be inclined, the same device as the refrigerating compartment temperature controller (11) that has been conventionally used can be provided. However, it suffices to install it upside down from the conventional installation method, and there is no need to manufacture a new device. The refrigerating room temperature controller (11) can be installed in the chilled room temperature controller (12) in exactly the same manner.

Next, regarding cooling of the chilled chamber (4) and the vegetable chamber (5), cold air is blown out through the duct (16) for the chilled chamber in the control box formed in the control box (10). It is blown out from 16a) and cooled. Thus, in this embodiment, since the chilled chamber duct (16) in the control box plays the role of the conventional connecting duct (13), the connecting duct (13) is provided on the rear wall of the refrigerating chamber (3) as in the conventional case. ) Need not be formed separately. That is, since the control box (10) is formed over the entire height of the rear part of the refrigeration room (3), the chilled room duct (16) in the control box is placed in the control box (10). Because it can be installed side by side with the duct (15) for
Therefore, the chilled chamber duct (16) in the control box can be formed at the same time when the control box (10) is created. Therefore, both the number of manufacturing steps and the cost of the refrigerator body (1) are reduced, and a simple and inexpensive refrigerator ventilation device can be provided.

By the way, in the above embodiment, the ventilation device in which the duct for the chilled room in the control box (16) is arranged on the right side of the control box (10) and the duct for the refrigerating room in the control box (15) is arranged on the left side in the front view. However, it is not necessarily limited to this arrangement. For example, the left and right arrangements may be reversed, or the front and rear arrangements may be arranged.

In addition, this control box (10) is the refrigerating room (3)
It should be formed over the entire height of the vegetable compartment (5) by further extending either the duct (15) for the refrigerating compartment in the control box or the duct (16) for the chilled compartment in the control box that are juxtaposed. May be up to.

[Effect of the Invention] As described above, the ventilation device for the refrigerator of the present invention is
A control box having a plurality of outlets for cold air is arranged on the back side of the refrigerating room in the refrigerator, and a refrigerating room temperature controller and a chilled room temperature controller are installed in the control box. It is arranged so that the temperature controller main body is located at a position higher than the height of the outlet portion, and the refrigerating room duct and the chilled room duct are arranged side by side in the control box. Cool air can be blown out from the outlet to the entire inside of the refrigerating compartment, and water droplets from the outlet of the rear duct must be applied to the refrigerating compartment temperature controller and the chilled room temperature controller. Moreover, since the chilled chamber duct formed in the control box plays the role of a connecting duct, it efficiently cools the inside of the refrigerating chamber and evens out the temperature distribution, thus controlling the temperature. Vessel is reliably actuated, yet can be simplified and inexpensive refrigerator ventilation device.

In addition, since the temperature controller body is placed in the foreground and the baffle is arranged diagonally in the front and rear direction, the vertical length can be shortened to save valuable space in the refrigerator and effectively utilize it. It can be useful for space saving,
The work and structure of the duct can be simplified.
