Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention discharges air cooled by a cooler, that is, cold air, into a refrigerator compartment and circulates it, and the temperature inside the refrigerator compartment is sensed through the outlet of the cold air. This relates to a refrigerator that automatically opens and closes using a damper thermostat.

(B) Prior Art In conventional refrigerators of this type, a damper thermostat that senses the temperature inside the refrigerator compartment and automatically opens and closes the cold air outlet to the refrigerator compartment is usually installed in the back wall of the refrigerator compartment. The inside of the refrigerator compartment is normally kept cool at about +3°C to +5°C by damper thermostats and controls. Here, raw meat, fresh fish, etc.
Conventionally, for foods that require cooling at a relatively low temperature, such as between ℃ and -5℃, a dish-shaped container is provided in front of the damper thermostat, and the cold air that has passed through the damper thermostat is pumped into the container from the upper opening of the container. A relatively large amount of the food is introduced into the container to form a low temperature space, and the food is stored in this container.

However, with such a configuration, there is a risk that the food will dry out and deteriorate in quality because it is directly exposed to a large amount of cold air. In addition, in order to prevent such drying, a nearly sealed space is created inside the refrigerator compartment, and a cold air passage is formed outside of this space, and this cold air passage, ? It has been considered to cool the space by directly introducing cold air from a refrigeration system, but this has the disadvantage that stable temperature control cannot be achieved because the temperature must be set depending on the shape of the cold air passage. .

e→ Purpose of the Invention The object of the present invention is to provide a refrigerator which cools the room by discharging cold air into the refrigerator compartment, and which has a space suitable for low-temperature storage in the refrigerator compartment.

B) Structure of the Invention The present invention cools the room by discharging cold air into the refrigerator room, and also includes a damper thermostat that senses the temperature in the room and automatically opens and closes the cold air outlet. A cold air passage is formed outside the cold room, cold air passing through a damper thermostand is directly supplied to the cold air passage, and the cold air passes through the cold air passage and flows into the refrigerator compartment. It is something.

(e)) Embodiments The present invention will be explained in detail with reference to the drawings. FIG. 1 shows a schematic perspective view of this type of refrigerator (1). The refrigerator (1) is constructed by filling a heat insulating material (4), which will be described later, between an outer box (2) made of steel plate and an inner box (3) made of synthetic resin. There is a freezer compartment (6) above which is cooled to freezing temperature and a refrigeration compartment (6) which is maintained above freezing temperature below.

(19 is a damper case. It is attached to the back wall of the refrigerator compartment (7) so as to cover the damper thermostat α5).The damper case (11 is a plastic case with a built-in molded heat insulating material, and communicates with the duct α9 inside to connect the back full plate α).
The space where the mark moves (2@) and the space (a) are discharged from the refrigerator compartment (window hole c21 that communicates with the force) and the discharge port a (a) on both sides, colliding with the bakful plate (IalK) and moving diagonally upward and forward. There are two induction ducts that directly direct some of the cold air.

The front of the damper case α9 is the cold storage room (upper part of the inside, the bottom plate is directly under the partition wall (5) (2nd floor, cold room case c! 4)
A low-temperature chamber (26) is formed in a substantially hermetically sealed manner from the mounting plate 05) and the like housed in the case (goods). Each enlarged perspective view is shown in FIGS. 3 to 5. The inside of the bottom plate (C) is filled with a heat insulating material, and a plurality of through holes (27) are bored therein. As shown in Fig. 4, the cold room case (Foundation) has a top surface and left and right surfaces (2g) (301 and a back plate C31 having a portion protruding outward from each surface), and
It consists of a closing plate 02 1.34) that protrudes outward from each of the above surfaces at the upper front and both sides, and is open forward and downward. A rail bent inward is formed on the lower edge of the left and right surfaces C29), and a mounting plate (2) is slidably supported on these rails G so that the case C24 ). As shown in Fig. 5, the mounting tray (c) has a handle part (g) on the front edge, and left and right side walls Gη (381 and a rear wall G39 rising at the rear side) rising on both sides from a little further back from the handle side. The front ends of the left and right side walls Qη (end) are formed with an inclined portion (4@) that slopes upwardly toward the rear, and the rear ends thereof are formed with engaging claws (4υ) that protrude to both sides. The engaging claw (4υ is formed at the tip of the elastic piece (41a) so as to have elasticity in the left-right direction, and has a shape that is inclined inward toward the back.The engaging claw (4υ) is formed at the tip of the elastic piece (41a) so as to have elasticity in the left-right direction, and has a shape that slopes inward toward the back. is formed with a protrusion (4 ridges) that slopes low toward the front, and the mounting plate (
When the two are pulled out from the case (goods), as shown in Figure 6, the engaging claw (4υ) comes into contact with the protrusion (421) to prevent it from falling due to excessive pulling out.
), first place the mounting plate 25) on the rail c.
351, and after the engaging claw (41) comes into contact with the protrusion (421), by pushing further, the engaging claw (41) slides on each inclined surface, and the engaging claw (41) is displaced inward. Installation is very easy because it is achieved by climbing over.

The lower opening of the case (2) is closed by storing the mounting tray, but the front opening is closed by the rotating lid (4th floor).The rotating lid (4th floor) is made of transparent resin, The left and right side surfaces (441) are approximately fan-shaped, and the front surface (441) is approximately arc-shaped in cross section. A hole (4) with a protrusion (4 front case (goods) left and right sides 09) m)

A protrusion (4al) located in front of the inclined part (40) of C) is formed. Therefore, by pulling out the mounting plate I2 (G) forward, the inclined part (41 comes into contact with the protrusion (481), and then the protrusion G4 rises along the inclined part (41) K, the rotary lid 0■ rotates clockwise in FIG. 2 and the front surface (4!

Rotates counterclockwise in Figure 2 to close the front opening of the °C case (24).Therefore, items can be delivered to the low temperature chamber (A) using the loading tray C!■
By pulling it toward you, you can easily remove items placed at the back.Also, the rotary lid 0□□□ opens and closes in conjunction with the loading tray (251), so you can save the trouble of opening and closing it.Case 04 The front part of the top surface (28) has a curved surface part (28a) that bulges upward so as not to support the rotating lid (49) when it moves upward.
) is formed.

With the back plate 0υ of the case (24) connected to the rear end of the bottom plate (c) and the closing plate 0■c34) connected to the front end, attach the bottom plate (
The left and right ends of the inner box (3) are inserted into and engaged with concave grooves (not shown) extending back and forth formed on both side walls of the inner box (3) to form a refrigerator compartment (7).
Install inside. At this time, the back plate 01 of the case (24)
is located immediately in front of the damper case α9 and abuts against the lower surface of the partition wall (5) and the inner surface of both side walls of the inner box (3) so as to partition the space above the bottom plate (23I) into front and back.
2 comes into contact with the lower surface of the partition wall (5) and engages with an engaging part (not shown), and the closing plate (to) G4) comes into contact with the inner surface of both side walls of the inner box (3) and closes the front opening of the case 04). The space above the bottom plate (2■) is partitioned into front and rear parts. Also, the lower edge of the left and right sides of the case (2!11 (G) is separated from the bottom plate (C), and the top surface (28) Because it is separated from the partition wall (5), the top surface (to) of the case (24), left and right surfaces 09) (3 (l)
l and directly placed (c) around the bottom surface of the partition wall (5) and inner box (3).
) and the bottom plate @, a cold air passage 60) is formed. An inlet port Gυ is formed in the part corresponding to the front of the damper case α9 (221 The cold air discharged from the cold air passage 60)
It flows inward, flows forward on the upper surface (C), and then branches to the left and right, flowing along the left and right surfaces C29) (toward), and some of it falls asleep (25).
It flows down into the refrigerator compartment (9) through a through hole (2η) that wraps around the bottom surface. This flow of cold air prevents the stored items from drying out.

Here, since the cold air introduced into the cold air passage 50) has passed through the damper thermostat 1, it is returned to the refrigerator compartment (9) so that the interior of the refrigerator compartment (7) is not overcooled.

Further, the cold air in the refrigerator compartment (9) is returned to the cooling compartment (not shown) through the intake port G'2.

A shaft 53) is protruded from the upper surface (C) of the case (24), and a manual damper harrow a is pivotally supported on the shaft 53) so as to be horizontally rotatable within the cold air passage (50). The manual damper 64) is pivoted approximately at the center, and has six damper plates located in front of the introduction port 61) at one end and can be opened and closed freely, and an operation part t56 that passes through the closing plate C321 and faces the front at the other end.
)have. By arbitrarily operating this manual damper G4), the amount of cold air flowing into the cold air passage 50) can be changed as appropriate. In other words, when storing items such as raw meat or fresh fish that need to be stored at relatively low temperatures (for example, around -5°C), the damper plate E! The inlet 61) may be opened at step 19. In addition, in the case of articles other than those mentioned above, for example, articles to be stored at about 0° C., the inside of the cold room Qe can be cooled to an appropriate temperature by semi-opening or closing the inlet 51. In addition, since there is a heat insulating material in the bottom plate (C), it is not easily affected by the temperature of the cold room (refrigeration room (7) in 2Q) (for example, about +3° C.), and independent temperature control is possible.

A part of the cold air discharged from the outlet a< of the duct α■ flows out from the left and right window holes (2υ), and flows out from the back plate G of the case (24).
It flows down the space behind υ and circulates inside the refrigerator room (7) to cool the room. An adjustment jacket (I57) extends forward from the damper case α9 through the damper case α9, and a knob 6υ is attached to the part located on the outer surface of the damper case (19) at the tip of the damper case α9. Here, the bottom plate (C) or rear plate C31) is in a shape that hides the damper case (just before 19, that is, the knob (5) from the front, and if it remains as it is, the damper thermostat α
It is impossible to adjust the set temperature of ω. That's why I picked it! i
An operating portion (58a) extending downward from the bottom plate (c) is integrally formed on υ to improve operability.

(F) Effects of the Invention According to the present invention, food in a low-temperature room is indirectly cooled from the cold air passage, so that quality deterioration such as drying does not occur. In addition, since the cold air that has passed through the damper thermostat is directly supplied to the cold air passage, it is possible to keep the temperature inside the low temperature chamber below 0℃, which has sufficient cooling capacity, and this cold air flows out to the refrigerator compartment. Therefore, there is no need to form a special cold air return path, and the structure is simplified. Furthermore, since the cold air supplied to the cold air passage is the cold air that has passed through the damper thermostat, the low-temperature room is cooled while maintaining a substantially constant temperature difference from the refrigerator compartment, and there is no risk of overcooling. Even if water is allowed to flow out, the inside of the refrigerator compartment will not be overcooled.
