Description

Refrigerator {REFRIGERATOR}

The present invention relates to a refrigerator.

In a conventional refrigerator, for example, when the compressor stops operating, the damper unit for the freezer compartment is opened to operate the blower to blow air into the refrigerating chamber while subliming frost attached to the evaporator to increase the humidity of the refrigerator compartment, Some foods retain moisture to maintain freshness.

In this conventional refrigerator, a damper unit for a freezer compartment is arranged in front of the blower (inward direction of the freezer compartment) so that cooling air is blown out in the entire freezer compartment. Such a refrigerator is described, for example, in Japanese Patent Laid-Open No. 2001-241825.

However, in the above-mentioned conventional refrigerator, since the damper unit for a freezer compartment is arrange | positioned in front of a blower, the dimension of an inside direction becomes large and the storage volume of the freezer compartment becomes small. In addition, the conventional refrigerator has a possibility that the amount of air discharged to the freezer compartment is reduced by increasing the air resistance. In addition, in the conventional refrigerator, since the damper unit that controls the air circulation of the freezer compartment is located in front of the blower, the cooler that is cooled by the evaporator and is heavier than before the cooling is lifted up to the intake port of the damper unit once located above the damper of the damper unit. There is a problem in that it is necessary to blow the air so that the blower needs more energy than necessary, and the power consumption increases.

In view of the above, a first object of the present invention is to provide a refrigerator in which the storage volume of the freezer compartment is reduced, and the pressure loss of the blower is reduced to reduce the power consumption.

In addition, since the conventional refrigerator has a configuration in which cooling air is blown out in the entire freezer compartment, it is difficult to shorten the ice making time and freeze the food in a short time when the high volume of the freezer compartment is increased. A second object of the present invention is to provide a refrigerator which can perform ice freezing or home freezing in a short time by intensively discharging cold cooling air to an ice maker or a quick freezing portion when ice freezing or home freezing food. There is.

In addition, in order to make the temperature distribution in the freezing chamber uniform even when the freezer compartment has a large internal volume, there is a technique to solve the problem by providing a large number of cold air outlets for discharging the cold air in the freezer compartment. It becomes small.

In addition, the cold air discharged from the cold air discharge port distant from the blower (the cold air discharge port downstream from the center of the plurality of cold air discharge ports) reduces the air volume by the passage resistance and slows the discharge flow rate, thus providing a plurality of cold air discharge ports. Even if it is, there exists a possibility that the temperature distribution in a freezer compartment may not be fully uniformized.

The third object of the present invention is to suppress the decrease in the effective inner volume of the freezer compartment when a plurality of cold air discharge ports are provided, and to keep the discharge flow rate from the downstream cold air discharge port so as not to be significantly different from the discharge flow rate from the upstream cold air discharge port. It is to provide a refrigerator aimed at equalizing the temperature distribution in the interior.

In addition, when the damper unit is provided, there is a problem that the volume of the damper unit or the volume of the driving unit for driving the damper invalidates the space in the refrigerator, thereby reducing the effective contents. It is a fourth object of the present invention to provide a refrigerator in which the damper unit or the drive unit for driving the damper is disposed where the effective content is not reduced, thereby increasing the effective content.

That is, an object of the present invention is to provide a refrigerator having a wide effective space in the refrigerator, a reduced power consumption, and a good usability.

The first object is to control the refrigerating chamber, a freezing chamber located below the refrigerating chamber, one evaporator, one blower for blowing the cooling air heat-exchanged with the evaporator, and blowing the blown cooling air to the freezing chamber. A freezer compartment damper unit and a refrigerator compartment damper unit for controlling the blowing of the blown cooling air to the refrigerating compartment, and the inlet of the cooling air of the freezer compartment damper unit is lower than the central axis of rotation of the blower so as not to overlap with the blower. Is achieved by

In other words, the refrigerator having the above-described structure suppresses the storage volume of the freezer compartment from being small, and eliminates the need for blowing heavy cold air to lift the blower upward, thereby reducing the pressure loss of the blower and reducing the power consumption.

The second object includes a partition wall in which the freezer compartment divides the freezer compartment from the front side to the left and right, and an ice making chamber or a rapid freezing chamber disposed at the top of one of the left and right sides of the freezer compartment partitioned by the partition wall. The damper unit is achieved by being a damper unit that controls the blowing to the ice making chamber or the quick freezing chamber.

A refrigerator having such a configuration can intensively install cold air cooled in an evaporator in an ice making chamber or a quick freezing chamber to perform ice making or home freezing of food in a short time.

Moreover, the 2nd objective is the partition wall which a freezer compartment divides this freezer compartment from the front side to the left and right, an ice-making chamber arrange | positioned at the top of either of the left and right sides of the freezer compartment partitioned by this partition wall, and the uppermost part of the other freezer compartment. It can also be achieved by arranging the damper unit which controls the blowing to the said ice-making chamber, and the damper unit which controls the blowing to the said ice-freezing chamber, right and left side by side. In the refrigerator having such a configuration, the damper unit is disposed in both the left and right directions, and the distance from the blower is shortened in both the ice making chamber and the quick freezing chamber disposed at the top of the freezing chamber, so that the cooling air from the blower can be intensively supplied at a short distance. By being there, it can freeze in a short time.

In addition, the second object is a refrigerator compartment, a freezer compartment, an evaporator for cooling the air in the refrigerator, a blower for blowing the cooling air heat exchanged with the evaporator, and a refrigerator compartment damper unit for controlling the blowing amount of the cooling air blown into the refrigerating compartment; And a freezing chamber damper unit for controlling an air blowing amount of the cooling air blown into the freezing chamber, wherein the freezing chamber introduces a cold air inlet for introducing an ice making chamber or a quick freezing chamber and cooling air whose airflow amount is adjusted by the freezing chamber damper unit. And a damper of the damper unit for the freezer compartment to stop the tip portion at an angle opposite to the cold air introduction portion.

That is, in such a refrigerator, when deicing or home freezing food, the front end of the damper is opposed to the front end of the cold air inlet of the cooling air, so that a lot of cooling air is concentrated through the inlet of the damper unit, and ice making or Can be frozen.

The second object is that the freezer compartment damper unit can smoothly blow the heavy cooling air cooled by the evaporator without raising the inlet of the cooling air below the rotational center axis of the blower.

The third object is that the freezer compartment connects a plurality of storage containers, a cold air introduction portion through which cooling air from a damper unit is introduced into the storage container or the storage container, and a cross-sectional area within the passage by connecting the damper unit and the cold air introduction portion. It is achieved by having a cold air discharge passage that becomes smaller toward the downstream.

In other words, the refrigerator having such a configuration is narrower as the inside of the cold air discharge passage is downstream, which prevents the flow rate in the cold air discharge passage from decreasing, and also allows the high speed air to flow into the container or shelf in which the stored food at each stage is placed. For each container or storage space, a cold air inlet for introducing cooling air is provided so as to narrow the cold air discharge passage so as to sense the air volume at the boundary of the cold air inlet. Thereby, the fall of the flow velocity of cooling air can be suppressed. As the cold air discharge passage is narrowed, the inside of the freezer compartment can be widened to increase the effective contents.

The fourth object is a refrigerating compartment, a freezing compartment, an evaporator for cooling the air in the refrigerator, a blower for blowing the cooling air heat exchanged with the evaporator, a refrigerating compartment damper unit for controlling the blowing amount of the cooling air blown into the refrigerating compartment, and A freezer compartment damper unit is provided for controlling the blowing amount of the cooling air blown to the freezer compartment, and the freezer compartment has a partition wall for partitioning the freezer compartment from side to side, and the freezer compartment damper unit, the drive unit of the freezer compartment damper unit. Is achieved by arranging a part of or the whole of the drive unit of the damper unit for the freezing compartment in the projection space of the partition wall viewed from the front.

That is, the effective content area can be enlarged by disposing the damper unit or the drive unit for driving the damper within the projected area of the partition member that does not reduce the effective content area.

As shown in Fig. 2, the refrigerator 1 according to the embodiment of the present invention includes a refrigerator compartment 2, a vegetable compartment 13, and a freezer compartment from above, and the freezer compartment is a right freezer compartment 3 and a left freezer compartment 4 from above. It is separated and the plural freezer compartment food storage container 19 is arrange | positioned inside. In addition, a quick freezing corner 17 is provided at the top of the right freezing chamber 3, and an ice maker corner 18 is provided at the top of the left freezing chamber 4. Moreover, the horizontal compartment member 16 which is a heat insulating material is arrange | positioned between the vegetable compartment 13 and the freezer compartment which have a large temperature difference in a refrigerator.

Fig. 1 is a schematic front view showing a main part of the arrangement of the damper unit of the refrigerator showing the first embodiment, wherein the damper units 6 and 7 for the freezer compartment are lower than the central axis of rotation of the blower 9 having the blades 9a. ). The cooling air cooled by the evaporator 8 flows into the freezer compartment through the cold air discharge passages 21 and 23 when the blower 9 is swiveled, and in particular, the cold air that has passed through the cold discharge passage 23 passes through the ice maker corner ( 18) (see FIG. 2) to supply cold air intensively. The air which cooled the freezer compartment flows in from the return cold air passage 12 for the freezer compartment, is cooled again in the evaporator 8 and circulated. In addition, the refrigerator compartment damper unit 5 supplies cooling air to the refrigerator compartment 2 and the vegetable compartment 13 (refer FIG. 2) provided above the freezer compartment.

In this case, in the case of rapidly deicing, the damper unit 5 which closes the refrigerating compartment damper unit 5 to prevent the cooling air of the positive temperature of the refrigerating compartment 2 from circulating and simultaneously blows the cooling air to the quick freezing corner 17 also has a damper unit. It is closed so that only the damper unit which blows cooling air to the ice maker corner 18 is opened. In this way, since about -27 degreeC cooling air cooled in the evaporator 8 is directly concentrated in the ice making pan 18a, the surface heat transfer rate of the ice making pan 18a raises, and it takes away heat quickly and makes ice making time. This is shortened. Similarly, when there is a storage item to be quickly frozen, the freezer compartment damper unit 5 and the freezer compartment damper unit 7 are closed to blow the cooling air to the quick freezing corner 17. By shortening the time, home freezing can be shortened and frozen food can be made in a short time.

Further, in the evaporator 8, by arranging the intake ports of the cooling air of the freezer compartment damper units 6 and 7 to be lower than the center of the blade 9a of the blower 9 as shown in Figs. It is not necessary to blow air to raise the cooled and heavy air upwards, and the pressure loss of the blower 9 is reduced, so that energy is not required and the refrigerator can be provided with reduced power consumption. In addition, since the inlet of the cooling air of the freezer compartment damper unit 6 does not overlap with the blower 9, the inside of the freezer compartment can be suppressed to be smaller by that amount, so that the storage volume of the freezer compartment can be reduced. have.

In addition, the refrigerator shown in FIG. 1 is provided with a damper unit that independently adjusts the flow of cold air to the quick freezer corner 17 and the ice maker corner 18, respectively, and arranges the damper unit in both the left and right directions of the freezer compartment. In the quick freezing corner 17 or the ice maker corner 18 disposed at the top, the distance from the blower 9 is shortened, and the cooling air from the blower 9 can be intensively supplied to the upper portion of any corner at a short distance. By so doing, ice making and home freezing of food can be performed in a shorter time.

Referring to Fig. 3 (a) in detail with reference to the freezer compartment damper unit 6, the damper 6b is a cold air introduction portion 21a for guiding cooling air to the quick freezing corner 17 in the case of a quick freezing operation. ) And its distal end are located opposite each other. Further, the positional relationship between the cold air introduction portion 21a and the freezer compartment damper unit 6 is arranged so that the point of the damper 6b is located upstream of the flow of cold air, and the damper 6b of the freezer compartment damper unit 6 is opened. By selecting the degree, for example, in the embodiment, the tip of the cold air introduction portion 21a and the damper 6b are in close proximity to each other at a position where the opening degree of the damper 6b is inclined downward by about 41 degrees. Almost all of the cooling air entering the suction port 6a of the unit 6 is discharged to the quick freezing corner 17 rather than the cold air discharge port 22 via the cold air introduction portion 21a.

In addition, when the damper unit 7 for a freezer compartment is explained in full detail using FIG.3 (b), the damper 7b will introduce the cold air | gas introduction part 23a which guides cooling air to the ice-making dish 18a when a rapid freezing operation is carried out. ) And its distal end are located opposite each other. In addition, the positional relationship of the cold air | gas introduction part 23a and the freezer compartment damper unit is arrange | positioned so that the point of the damper 7b may be upstream of the flow of cold air, and the damper unit 7 for freezer compartments may be selected by selecting the opening degree of the damper 7b. Almost all of the cooling air that enters the suction port 7a is discharged from the cold air discharge port 24 to the ice maker corner 18 via the cold air introduction portion 23a. Thus, it has the ice maker corner 18 or the quick freezing corner 17 in which the ice maker was arrange | positioned in the freezer compartment, and the cold air introduction part 21a or 23a for introducing the cooling air from the damper unit for freezer compartments, The unit 6 or 7 adjusts the blowing to the ice maker corner 18 or the quick freezing corner 17 so that the opening and closing angles of the dampers 6b and 7b of the freezer damper units 6 and 7 can be adjusted or selected. The opening and closing angles are adjusted or selected so that the tip ends of these dampers are close to the tip ends of the cold air introduction portion 21a or 23a so that the tip ends of the dampers are cold air of the cooling air when deicing or food freezing. It is possible to make ice or freeze in a short time by concentrating the mounting of a lot of cooling air via the inlet of the damper unit opposite to the tip of the inlet.

4 is a longitudinal sectional view of the refrigerator showing the positional relationship between the refrigerator compartment damper unit and the freezer compartment damper unit. When supplying cooling air with a high flow rate to each freezer compartment food storage container 19 in the right freezer compartment 3 located below the quick freezer corner 17, the freezer compartment damper unit 6 is fully opened. The cross-sectional area of the passage is narrowed toward the downstream of the cold air discharge passage 21 leading downward of the freezer compartment damper unit 6 to prevent the wind speed in the cold air discharge passage 21 from decreasing. That is, in order to introduce cooling air having a high flow rate into each freezer compartment food storage container 19, the cold air introduction portion 21a of the cool air is provided for each cold air outlet 22 of the cold air discharge passage 21 to each freezer compartment food storage container. It installs and narrows a passage | path so that a quantity of air may be sensed with respect to each cold air | gas introduction part 21a. In addition, as the cold air discharge passage 21 is moved downstream, the inside of the right freezer compartment is made wider to increase the effective contents, thereby increasing the contents of the container.

Fig. 5 is a schematic front view showing the relationship between the drive members of each partition member and each damper unit of the refrigerator showing the second embodiment of the present invention. The drive unit of each damper unit 5, 6, 7 is a horizontal compartment member 16 partitioning the refrigerator compartment 2 and the vegetable compartment 13 and a freezer compartment compartment compartment partitioning the right freezer compartment 3 and the left freezer compartment 4. By placing the refrigerator 1 in the projection area when the refrigerator 1 is seen from the front of the 14 or in the projection area of the ice making dish 18a when the refrigerator 1 is seen from the front, each damper unit is brought into the inside of the refrigerator. The protrusions are made smaller and the effective contents are made larger.

As shown in Figs. 6 and 7, the freezer compartment compartment segment member 14 has a through hole 14a, and the sensor for temperature measurement used when performing the temperature control in the freezer compartment in the through hole 14a ( 15) Since the sensor 15 is provided in the through hole 14, it can be shared by the left and right freezer compartments, and the manufacturing cost can be reduced by reducing the number of parts, and the left and right freezer compartment temperatures can be equalized.

Freezer compartment damper unit 6, in which the quick freezing corner 17 shown in Fig. 3A is preferred, and freezer damper unit 7, in which cooling of the ice maker shown in Fig. 3B is preferred. And the ice maker corner 18 and the quick freezing corner 17 are disposed below each damper unit, so that each ventilation path can lead to the shortest and simplest structure, so the parts cost is low and the assembly time is short. You can provide an affordable refrigerator.

As described in detail above, according to the embodiments, the cooling air is intensively discharged by the method of opening the damper unit of the compartment to be rapidly cooled and closing the damper unit of the other compartment, thereby increasing the amount of air and increasing the surface heat transfer rate. The larger the ice, the shorter the ice making time, and the shorter the time for home freezing. And since the time for home freezing is shortened, a food can home freeze the taste in a state better than before, and can also lengthen a shelf life.

In addition, since the damper unit for discharging cooling air to the quick freezing corner or the ice maker corner is located at a position lower than the center of the blade of the blower, the heavy cooling air cooled in the evaporator flows smoothly into the freezer without lifting the blower. Therefore, the blower does not need to use that much energy, thereby saving power.

As the passage through which cooling air flows becomes smaller downstream, the passage cross-sectional area becomes smaller, so that cooling air without inferior wind speed can be discharged on each freezer compartment food storage container or shelf, and each container can be cooled uniformly.

The drive unit of the damper unit which adds or subtracts the amount of air discharged to each compartment is arranged in the projection surface of the partition member between each compartment of the refrigerator, or the ice maker views the drive unit of the preferred damper unit from the front of the refrigerator within the projected area of the ice maker. Since it is arrange | positioned, the drive part of a damper unit can suppress that the space in a freezer is made small, and the effective content in a refrigerator can be made large by that much.

According to the present invention, it is possible to provide a refrigerator having a wide effective space in the refrigerator, reduced power consumption, and good use.
