Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator, and more particularly to a refrigerator in which a drawer type door is arranged in one room of a refrigerator body.

[0002]

2. Description of the Related Art Conventionally, one or a plurality of drawer-type doors are arranged in a refrigerator, and a container for storing items is attached to the back of the refrigerator so that the container is located in the chamber. There is a refrigerator configured to be pulled out from the one room by pulling out a drawer type door.

For example, in a conventional refrigerator 100 shown in FIG. 8, a freezer compartment 104 partitioned by two partition walls 101 and 102 is provided inside a refrigerator main body which opens to the front.
The freezer compartment 104 has two containers 10 at the top and bottom.
6, 107 are arranged. These containers 106, 10
7 is configured to be supported by container supports 110 and 111 attached to the back surfaces of the upper and lower freezer compartment doors 108 and 109, respectively, and to be drawn forward by the respective doors 108 and 109.

In order to seal the cold air in the freezer compartment 104, a gasket 112 having a magnet inserted therein is attached to the peripheral edges of the back surfaces of the freezer compartment doors 108 and 109.
An elongated partition plate 113 is horizontally attached to the opening edge of the freezing chamber 104 between the doors 108 and 109, and the gasket 112 abuts on the opening edge of the freezing chamber 104 and the partition plate 113, whereby the freezing chamber 104 is closed. Is configured to be closed.

Behind the freezer compartment 104 is an evaporator 11
4 are arranged, and cool air is stored in the refrigerator 1 above the evaporator 114.
A fan 115 that circulates in 00 is arranged. Further, on the rear surface of the freezing compartment 104, which extends forward along the ceiling surface of the freezing compartment 104, and which sends the cool air to the upper container 106 over substantially the entire width, and an upper duct 116 which is located substantially in the center of the rear surface. A central duct 117 is formed in the rear portion of the lower container 107 to feed cold air over substantially the entire width.

In this refrigerator 100, the evaporator 114
The chilled air cooled by the air is cooled by the fan 115, as indicated by the dashed-dotted line arrows in the figure.
Flow into the freezer compartment 104 from the outlet of the upper duct 1
The cool air from 16 flows forward in the upper container 106, passes through the ventilation hole 118 provided at the front upper end of the container 106, and the container 106 and the door 108 in front thereof.
Between the container 107 and the door 109 in front of the container 107 through the ventilation hole 119 provided in the upper front part of the lower container 107. It flows in, is guided to the lower duct 120 provided in the lower partition wall 102, and flows out from the freezer compartment 104. Further, the cool air from the central duct 117 flows forward in the lower container 107, and from the container 107, the ventilation holes 11 are formed.
9 and flows between the container 107 and the door 109,
It is guided to the lower duct 120. By circulating the cool air in this way, the inside of the freezer compartment 104 is cooled.

[0007]

Generally, in a refrigerator, when cold air is sealed by the gasket 112, the heat leakage due to the gasket 112 is large enough to account for about 40% of the total heat leakage of the refrigerator. Therefore, the temperature of the front portions of the containers 106 and 107 located near the doors 108 and 109 becomes higher than that of the rear portions, and there is a problem that a uniform temperature distribution cannot be obtained. Here, in order to improve the heat insulating property of the gasket 112 itself, it may be possible to enclose a heat insulating material in the gasket 112, but in that case, it is extremely difficult in manufacturing, and it is necessary to significantly change the equipment and increase the cost. Become.

Further, the partition wall 101 and the partition plate 113 are
For the purpose of preventing dew condensation, a heat radiating pipe, a heater, etc. are embedded inside, and this radiates heat to the inside of the refrigerator to cause heat leakage to the freezer compartment 104. This is a factor that raises the part temperature and hinders uniform temperature distribution.

Therefore, in order to prevent such heat leakage, conventionally, as shown in FIG. 9, a rib 121 that abuts against the front upper edge of the upper container 106 from the ceiling surface of the freezer compartment 104 is hung down, or As shown in FIG. 8, the partition plate 113
1 that comes into contact with the upper front edge of the container 107 below from the lower surface of the
22 is attached.

However, even in this case, heat enters the freezing chamber 104 through the gap between the front upper edges of the containers 106 and 107 and the doors 108 and 109, as shown by the wavy arrows in the figure. Ventilation holes 1 of the containers 106 and 107
The temperature of the cold air flowing out from the nozzles 18, 119 is raised. As a result, the temperature of the front part of the freezer compartment 104 becomes high, and there is a problem that a uniform temperature distribution in the containers 106 and 107 cannot be obtained. In addition, in this case, the gasket 11 of the partition plate 113 or the partition wall 101 is formed by the gap.
2 There is also a problem that the temperature of the contact surface becomes low, which causes factors such as dew condensation.

On the other hand, the cold air flowing downward from the upper container 106 flows downward along the rear surface of the partition plate 113, does not flow into the front portion of the lower container 107, and is short-circuited to allow ventilation. It flows out from the hole 119 to the front of the container 107. Further, the central duct 117 is provided in the freezer compartment 1.
04 is formed to project short from the rear surface, and the cool air from there is introduced into the rear portion of the lower container 107, so that the stored items in the front portion thereof are not directly exposed to the cool air. Therefore, there is a problem that the temperature difference between the front part and the rear part is large especially in the container 107 below this, and a uniform temperature distribution cannot be obtained.

Further, since the upper and lower containers 106 and 107 are provided with the ventilation holes 118 and 119 only on the front walls thereof, the cold air that has flowed into the containers 106 and 107 from the rear goes straight to the ventilation holes 118 and 119. In some cases, the cold air does not flow to the left and right sides of the containers 106 and 107 because it flows out from the 119. Also in this case, in particular, the duct 116,
There is a problem that the temperature of both sides of the container front part far from the outlet of 117 becomes poor and a uniform temperature distribution cannot be obtained.

As described above, if a uniform temperature distribution cannot be obtained in the freezer compartment 104, in order to cool a high temperature part to a certain temperature or lower, the cooling capacity and the amount of cold air are increased to make it unnecessary. Must be cooled. Therefore, there is a problem that efficient cooling cannot be performed, such as an increase in power consumption.

Therefore, in view of the above points, the present invention provides a refrigerator in which a drawer type door is arranged in one room of the refrigerator main body,
It is an object of the present invention to provide one capable of efficiently cooling the inside of the one chamber.

Never leak to.

Therefore, the cold air path 37 and the containers 30, 32 are
It is possible to prevent the temperature of the cold air flowing through the front part from rising, and it is possible to perform efficient cooling.

Also, due to the above-mentioned thermal cutoff, the cool air does not reach the contact surface of the partition wall 12 or the partition plate 28 with the gasket 26 and the temperature of the part does not become low, and there is dew. There is no.

Since the side surface ventilation holes 46 are provided on both the left and right side surfaces of the containers 30 and 32, cool air satisfactorily flows to the left and right sides of the front portions of the containers 30 and 32, and the portions are effectively cooled. Further, since the area of the ventilation holes is large, the flow of cold air is smooth and the front portions of the containers 30 and 32 are cooled well.

Since the cool air is gradually throttled from the wide space behind the ventilation hole 36 to the ventilation hole 36 by the rear side cool air guiding portion 44 provided behind the front ventilation hole 36, the pressure loss at that time can be reduced. it can. Further, the front-side cool air guide portions 40 and 42 provided in front of the front ventilation hole 36 can reduce the pressure loss when the cool air is blown out from the ventilation hole 36 and smoothly guide the cold air to the cold air passage 37. it can. In this way, the pressure loss before and after the front ventilation hole 36 can be reduced.

By the cool air introduction plate 58 provided on the rear surface of the partition plate 28, the cool air flowing downward from the cool air passage 37 in front of the upper container 30 flows into the front portion of the lower container 32 to cool the front portion. can do. That is, as in the conventional case, the cold air flows along the rear surface of the partition plate 28 and the lower container 3
The short circuit does not flow into the front ventilation hole 36 of No. 2 as it is.

There is a function and effect. Therefore, conventionally,
Since the front part of the freezer compartment 16 which tends to have a high temperature is effectively cooled, the temperature distribution becomes uniform, and the freezer compartment 16 is efficiently cooled. In addition, although the air chamber 28a of the ear-shaped portion 48 of the gasket 26 is not necessarily required, it is preferable to provide the air chamber 28a because the heat insulating effect is high. In addition, in the above, the cold air introduction plate 58 may be provided integrally with the partition plate 28 or as a separate piece.

Next, a refrigerator according to a second example of the present invention will be described with reference to FIG. Only differences from the above-described first example will be described.

In this example, heat leakage from the upper gasket 26 and the partition wall 12 is caused by the door panel 3 on the rear surface of the door 20.
9 and the front wall extending portion 38 of the container 30 are shielded by bringing them into contact with each other via a sealing material 70. That is,
The upper side gasket 26 of the freezer compartment door 20 is not provided with the ear-shaped portion 48 and is formed in the same shape as the other three sides. Then, the convex portion 72 of the door panel 39 protruding rearward
A sealing material 70 made of foam resin is attached to the horizontal upper surface of the door 20 over substantially the entire width of the door 20. Furthermore, container 3

The front end portion of the blower nozzle 80 is supported by placing 2.

By providing the air-blowing nozzle 80 having the above structure, cool air can be satisfactorily sent to the front part of the lower container 32, the temperature difference in the container 32 can be reduced, and effective cooling can be performed. Become.

Since the blowing nozzle 80 is removable, it is easier to manufacture than the case where it is integrally provided. Further, since the dead space between the upper and lower containers 30 and 32 is originally unable to store the stored items, the storage space is not reduced by the blower nozzle 80.

[0064]

According to the refrigerator of claims 1 and 2, since the cold air flowing from the ventilation holes to the front of the container is not warmed and the temperature of the front part of the container does not rise, the temperature distribution in the room becomes uniform. , Efficient cooling becomes possible. Further, since the temperature of the contact surface of the main body with the drawer type door does not decrease, dew does not adhere to that portion.

According to the refrigerator of claim 3, the pressure loss of the cool air before and after the ventilation hole of the container can be reduced, so that the cooling can be efficiently performed.

In the refrigerator according to the fourth aspect, the side ventilation holes allow the cool air to satisfactorily flow to the left and right sides of the front portion of the container and effectively cool the portion. Also, because the side ventilation holes are provided,
Since the area of the ventilation hole becomes large, the flow of cool air becomes smooth and the front part of the container is cooled well. Therefore, the temperature distribution becomes uniform and efficient cooling becomes possible.

According to the fifth aspect of the refrigerator, the cold air flowing out from the upper container can be sufficiently flown into the lower container. That is, unlike the conventional case, the cold air from the upper container does not flow into the ventilation holes of the lower container in a short circuit as it is, so that the front portion of the lower container can be efficiently cooled.

According to the refrigerator of claim 7, since the cool air can be satisfactorily sent to the front part of the lower container, efficient cooling is possible.
