[Problem to be solved by the invention]

The conventional refrigerator-freezer is configured as described above, and since the temperature regulators 8 and 9 in the control room 7 obstruct the flow of cold air, and because the cold air that has previously descended is raised upward again, the cold air The flow was not smooth, and as a result, there were problems such as uneven temperature inside the refrigerator.

Furthermore, since a separate component (holding case) for attaching the temperature regulators 8 and 9 to the upper rear surface of the refrigerator compartment 6 is required, there is also the problem that the cost is relatively high.

This invention was made to solve the above-mentioned problems, and it can smooth the flow of cold air to even out the temperature inside the refrigerator. It is an object of the present invention to provide a refrigerator-freezer that does not require the above-mentioned functions and can therefore realize cost reduction.

[Means to solve the problem]

The refrigerator-freezer according to the present invention includes a first air path penetrating in a double direction provided in an insulating partition wall that partitions an upper freezer compartment side and a lower refrigerator compartment side; A second air passage that guides cold air from the cooler room on the freezer compartment side; and a second air passage that is connected vertically below the first air passage and guides cold air from the same air passage to the refrigerator compartment side. 3 air passages, and a temperature controller that controls the flow of cold air passing through each air passage to adjust the temperature of the refrigerator compartment is directly attached to the heat insulating partition wall. .

[Effect]

In this invention, the first air passage and the third air passage are connected in a double series, and the cold air passing through both the air passages is controlled by the heat insulating partition wall provided with the first air passage. This is done with a directly attached temperature controller. Therefore, the cold air flowing sequentially from the second air path to the first air path and the third air path falls smoothly from top to bottom, and the flow is not obstructed by the air path.

Furthermore, the temperature regulator does not obstruct the flow of cold air.

Therefore, the temperature distribution inside the refrigerator is greatly improved.

Furthermore, since the temperature regulator is directly attached to the heat insulating partition wall, no special parts are required for that purpose.

〔Example〕

Figures 1 to 4 are diagrams showing one embodiment of the present invention.
The figure is a front view of the inside of the refrigerator, Figure 2 is a vertical side view of Figure 1, Figure 3 is an enlarged front view of the control room, and Figure 4 is IV-r of Figure 3.
It is a sectional view taken along the V line, and portions similar to those of the conventional device are designated by the same reference numerals.

In the figure, 5A and 5B are heat insulating partition walls (hereinafter referred to as dividers) 23 that partition the freezer compartment 2 side and the refrigerator compartment 6 side.
These are an air passage for the refrigerator compartment and an air passage for the chilled room that penetrate in the vertical direction. The air passage 5 is branched into the two air passages 5A and 5B. A control room 21 is made of a heat insulating material and is provided over the entire height of the refrigerator compartment 6. On the back side thereof, a refrigerator compartment air passage 21a is connected to the refrigerator compartment air passage 5A so as to be located below the refrigerator compartment air passage 5A, and is arranged in the vertical direction.
and is connected to the chilled room air passage 5B so as to be located below the air passage 5B, and communicates with the chilled room 1.0,
The chilled room air passages 21b arranged in the vertical direction are also arranged in parallel. In addition, a plurality of cold air outlets 21c to 21e are formed at different heights on the trr side of the control room 21, and each of them is arranged in front of the chilled room air passage 21b, so that the entire width of the control room 21 is It is formed over a period of time.

A refrigerator room temperature controller 8 and a tilt room temperature controller 9 are installed in the refrigerator room air path 5A and the chilled room air path 5B, respectively, so as to be located above the air paths 21a and 21b. ing. That is, both the regulators 8.9 have main bodies 8a, 9a, baffles 8b,
It is directly attached so that it is above 9b and so that the main bodies 8a and 9a are horizontal.

A partition wall 21f whose tip extends diagonally downward and a trapezoidal partition 21g are provided below the refrigerator temperature regulator 8, and the upper side of the partition wall 21g is at least above the tip of the partition wall 21f. It is formed to be located at. That is, the refrigerator compartment air passage 21a has an air passage that rises between the partition walls 21f and 21g and then descends, and the portion between the partition walls 21f and 21g serves as a cold air trap. 22 is a partial panel that covers the front surface of the control room 21.

In the Zawata refrigerator air passage device configured as above,
The cold air from the cooler room 3 is divided into two parts by the air path 5 and passes through the refrigerator room air path 5A and the chilled room air path 5B. The cold air passing through the chilled room air path 5B is regulated by the temperature controller 9,
It descends through the chilled room air passage 21b and is blown out into the chilled room 10. On the other hand, the cold air that has passed through the refrigerator room air passage 5A is regulated by the temperature controller 8, and is controlled by the partition walls 21f and 21g.
After passing through the air path between them, the cool air is blown out into the refrigerator compartment 6 from the cold air blow-off ports 21c to 21e.

At this time, since the upper side of the partition wall 21g is located higher than the tip of the partition wall 21f, when the blower 4 is stopped, the cold air does not cross over the cold air trap.

Therefore, when cold air flows back, the temperature controller 8. Dew condensation and freezing do not occur in the refrigerator compartment air passages 21a, 5A and the cooler compartment 3.

As mentioned above, in this embodiment, the temperature controller 8,
9 is directly attached to the divider 23 with the baffle facing down so that it is located above the air passages 21a and 2fb, so the cold air falls smoothly and the flow is very smooth. Temperature distribution is also improved. On top of that,
Since no special parts are required for the installation of the temperature regulator 8.9, the construction is very simple and therefore the cost is low.

Moreover, since the blow-off ports 21c to 21e are not provided in plurality and are formed over the entire width of the control chamber 21, the cold air is blown out over the entire height at the center of the refrigerating chamber 6, and the temperature distribution becomes uniform.

In the embodiment, when the control room 21 is viewed from the front, the left side is the refrigerating room air passage 21a, and the right side is the chilled room air passage 21b, but of course the opposite may be used.

In addition, if the main bodies 8a and 9a of the temperature regulator 8.9 are installed by fitting them into the deviter 23 and that part is sealed,
Water can be prevented from entering the main bodies 8a and 9a.

(Effects of the Invention) As explained above, according to the present invention, the air passage that penetrates in the vertical direction provided in the insulating partition wall that partitions the upper freezer compartment side and the lower refrigerator compartment side and the refrigerator compartment side. The air passages that guide cold air are connected vertically, and the temperature regulator that controls the flow of cold air through the air passages is directly attached to the above-mentioned insulating partition wall, so the flow of cold air is smoothed and the temperature inside the refrigerator is maintained. It can be made uniform.

Furthermore, since the temperature regulator is directly attached to the heat insulating partition wall as described above, there is no need for any parts required for this purpose as in the past, and costs can be reduced accordingly.
