Description

Refrigerator {refrigerator}

The present invention relates to a refrigerator, and more particularly, to a refrigerator capable of independently cooling a refrigerator compartment and a freezer compartment.

In general, the refrigerator is one of the necessities of life as a device that keeps food fresh for a certain period of time by lowering the inside of the refrigerator as the refrigerant (working fluid) repeats the refrigeration cycle of compression, condensation, expansion and evaporation.

Such a refrigerator includes a compressor for raising / heating a low temperature / low pressure gas refrigerant to a high temperature / high pressure gas refrigerant, a condenser for condensing the refrigerant introduced from the compressor by outside air, and a narrow diameter compared to the diameter of other parts. It consists of an expansion valve for reducing the refrigerant introduced from the condenser, and the evaporator which absorbs the heat in the refrigerator as the refrigerant passing through the expansion valve in a low pressure state as a basic component constitutes a refrigeration cycle.

Hereinafter, a conventional side-by-side refrigerator and a top mount refrigerator will be described with reference to the accompanying drawings.

First, Figure 1 is a perspective view schematically showing a conventional side-by-side refrigerator structure, Figure 2 is a perspective view schematically showing a conventional top-mounted refrigerator structure, as shown, the refrigerator is an evaporator (4) Most of the cold air heat exchanged by the inlet flows into the freezer compartment 1, which maintains the internal temperature of about -18 ° C, and part of the cold air heat exchanged by the evaporator 4 flows into the internal storage of about 0-7 ° C. It is largely divided into a refrigerating chamber that maintains temperature.

At this time, the freezing chamber 1 and the refrigerating chamber 2 are partitioned by the barrier 3.

The refrigerator configured as described above is operated by receiving a control signal from a controller (not shown) in the freezer compartment 1 and the refrigerating compartment 2 while supplying power in a state in which food is filled in the freezer compartment 1 and the refrigerating compartment 2. In (4), a heat exchange environment is created.

Therefore, the cold air passing through the evaporator 4 is lowered by heat exchange with the evaporator, and is discharged into the cold air flow path on the freezer compartment side by the operation of the blower fan 6. Subsequently, some of the cold air flows into the freezing chamber 1 through a cold air discharge port (not shown), and a part of the cold air flows into the cold storage chamber 2 through a cold air cold communication port (not shown). Thereafter, the cold air that has been heated while circulating the freezing compartment 1 and the refrigerating compartment 2 forms a cold air circulation structure in which heat is introduced into the evaporator 4 through a cold air intake port (not shown) and heat exchanged.

However, these conventional refrigerators are provided with one evaporator 4 on the freezer compartment side, and the cold air heat exchanged through the evaporator 4 is naturally distributed to some refrigerating compartments 2 on the cold air passage 10 on the freezer compartment side. There was a problem with the following structure because it was introduced.

First, in the refrigerator having a conventional structure, the compressor and the blower fan must be operated to lower the temperature in the refrigerator, which is not satisfied even if the temperature in either the freezer compartment 1 or the refrigerator compartment 2 is not satisfied, causing unnecessary power consumption. There was a problem.

For example, even when the temperature of the freezer compartment 1 is satisfied, if the temperature of the refrigerator compartment 2 is not satisfied, the temperature of the refrigerator compartment should be lowered by operating a compressor and a blower fan to satisfy the temperature of the refrigerator compartment. Since the temperature is also supplied to the freezer compartment 1, which is already satisfied, unnecessary cold air is supplied, which leads to unnecessary waste of power consumption.

Next, the refrigerator having a conventional structure has a problem that the cooling rate is relatively lower than that of the freezing chamber 1 because the amount of cold air distributed to the refrigerating chamber 2 after passing through the evaporator 4 is small.

That is, even though the set temperature of the refrigerating compartment 2 is higher than that of the freezing compartment 1, the cooling rate of the refrigerating compartment is lowered due to the small amount of air flow.

The present invention has been made to solve the above problems, by allowing each of the freezer compartment and the refrigerating compartment to be independently cooled to improve the cooling efficiency and to reduce the power consumption, while the refrigerating compartment was relatively slow compared to the refrigerator compartment in the conventional refrigerator The purpose is to provide a refrigerator to improve the cooling rate of the.

Still another object of the present invention is to provide a refrigerator capable of achieving the above objects and increasing the volume of the refrigerator.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings of the present invention.

First, the first embodiment of the present invention will be described in detail with reference to FIGS. 3, 4A, 4B, and 11 as follows.

3 is a perspective view schematically illustrating a refrigerator structure according to a first embodiment of the present invention, in which one evaporator and two blowing fans are installed in a freezer compartment of a side by side refrigerator, and FIG. 4A is FIG. 4B is a reference diagram for explaining the evaporator structure of FIG. 4A.

11 is a reference diagram for explaining a refrigerator structure according to a first embodiment on a refrigeration cycle.

A refrigerator according to a first embodiment of the present invention includes a freezer compartment (1), a refrigerating compartment (2) installed adjacent thereto, a barrier (3) separating the freezer compartment (1) and a refrigerating compartment (2), and the freezer compartment. An evaporator 4 installed at (1) to constitute a refrigeration cycle, a partition wall 9 dividing the heat exchange area of the evaporator 4 into two, and a partition wall 9 in cold air introduced into the evaporator 4 and heat-exchanged. Cold air flow path (A) for a freezer compartment formed to send the cold air of one region divided by) to the freezer compartment (1), and the other region divided by the partition wall (9) of the cold air introduced into the evaporator (4) and heat-exchanged Cold air flow path (B) for the refrigerating compartment formed to send the cold air to the refrigerating compartment (2), and the cold air flow passage (A) for the freezer compartment and the cold air flow passage (B) for the refrigerating compartment, respectively, and forcibly circulating the cold air into each chamber It is comprised including the blowing fan 105 (205).

At this time, the heat exchange region of the evaporator 4 is divided by the partition 9 to have different heat exchange areas.

The heat exchange area of the evaporator 4 divided by the partition 9 is larger in the freezer compartment side region F (see FIG. 11) than in the refrigerator compartment side region R (see FIG. 11).

On the other hand, the fin pitch of the freezing chamber (F chamber) side region and the refrigerating chamber (R chamber) side region of the evaporator 4 divided by the partition wall 9 may be set the same or different, it is set differently In this case, as illustrated in FIG. 4B, the pin pitch of the freezer compartment side region is preferably narrower than that of the refrigerator compartment side because frost easily forms on the pin of the refrigerator compartment side region.

In addition, a defrost heater (not shown) may be installed below the evaporator 4 to remove frost formed in the freezer compartment side region and the refrigerating compartment side region. At this time, a heater having a small capacity is provided below the freezer compartment side region of the evaporator. Is installed, and a heater having a large capacity is installed below the refrigerating compartment side region.

As the heater, a radiant heat heater is preferably applied.

In addition, a groove is formed on the surface of the partition 9 that divides the heat exchange area of the evaporator 4 so as to form a groove for forming a turbulent layer for cold air flowing along the surface of the evaporator 4. Improve heat exchange efficiency on the surface.

In addition, the freezer compartment cold air flow path (A) and the refrigerating compartment cold air flow path (B) is connected to each other, the damper (8) for concentrating the cold air into the other refrigerator when one of the internal temperature is satisfied on the flow path (C) connected to each other Is preferably installed.

As the evaporator 4, a straight type thin heat exchanger is applied, and as the blower fans 105 and 205, an axial flow fan or a sirocco fan is applicable.

On the other hand, as a fan provided in the cold air flow path (A) for the freezer compartment and the cold air flow path (B) for the refrigerating chamber, it is more preferable that a sirocco fan, which is a centrifugal fan, is used, which uses a thin heat exchanger as the evaporator (4). 1) This is because the evaporator installation space in the rear is narrower than before.

The operation process of the refrigerator according to the first embodiment of the present invention configured as described above is as follows.

When the heat exchange environment is established in the evaporator 4 by the operation of the compressor 30, the blower fans 105 and 205 respectively installed in the freezing chamber cold air flow path A and the refrigerating chamber cold air flow path B operate to operate. Cold air is forced to circulate.

At this time, the cold air circulating in the freezer compartment 1 and the refrigerating compartment 2 is introduced through each cold air intake port, and is heat-exchanged while passing through the freezer compartment side region and the refrigerating compartment side region of the evaporator 4, respectively. ) And the cold air flow path B for the refrigerating chamber is repeated to discharge the freezing chamber 1 and the refrigerating chamber 2.

Therefore, as the refrigerator according to the first embodiment of the present invention independently cools the freezing compartment 1 and the refrigerating compartment 2 by one evaporator 4 and two blowing fans 105 and 205, cooling efficiency is achieved. It can improve the power consumption and reduce the power consumption.

In particular, the freezer compartment cold air flow path (A) and the refrigerating compartment cold air flow path (B) is connected to each other, and the damper (8) is installed on the flow path (C) connected to each other, if the temperature in any one of the refrigerator is satisfied first By opening the damper 8 and sending the cold air past the high internal evaporator whose temperature is satisfied to the temperature where the internal temperature is not satisfied, it is possible to concentrate the cold air to one side to satisfy the unsatisfactory internal temperature in a short time.

At this time, since the high inner blower fan having a satisfactory temperature does not need to operate, power consumption can be reduced.

That is, the refrigerator according to the first embodiment has the advantage that the power consumption can be effectively reduced by stopping the fan on the side where the high internal temperature is satisfied because two fans are applied.

In addition, it is possible to improve the cooling rate of the refrigerating compartment 2, which has a relatively low cooling rate compared to the freezer compartment 1 in the existing refrigerator, and to expand the volume of the refrigerator.

That is, according to the present embodiment, since the freezing compartment 1 and the refrigerating compartment 2 are independently cooled, the amount of cold air that is distributed to the refrigerating compartment 2 after passing through the evaporator in the related art is relatively small, and thus the freezing compartment 1 is relatively free. The problem of lowering the cooling rate is solved.

In addition, according to the present embodiment, by applying a straight type thin heat exchanger as the evaporator 4, it is possible to reduce the thickness of the evaporator to reduce the space required for the installation of the evaporator to increase the internal volume of the freezer compartment (1).

That is, by replacing the existing evaporator with one evaporator by installing the thin evaporator 4 in the existing position, it is possible to maximize the content of the freezer compartment 1 without causing a loss in the contents of the refrigerating compartment 2.

In addition, according to the present embodiment, since the cold air passages circulating in the freezing compartment 1 and the refrigerating compartment 2 can be separated separately, the smells of the foods stored in the freezing compartment 1 and the refrigerating compartment 2 interfere with each other. It can also be prevented.

On the other hand, according to this embodiment, the fin pitch of the region of the refrigerator compartment R chamber side of the evaporator 4 divided by the partition 9 is equal to the pin pitch of the region of the freezer compartment side as shown in Fig. 4B. By being configured to have a wider gap, it is possible to prevent the phenomenon of frost easily formed on the refrigerator compartment side.

As described above, the interval between the pin pitch is configured so that the freezer compartment side region of the evaporator 4 is narrower than the refrigerator compartment side region, and the frost formed on the freezer compartment side region and the refrigerating compartment side region is removed from the bottom of the evaporator 4. A commercial heater (not shown) may be installed. At this time, a small capacity heater is installed under the freezer compartment side region of the evaporator, and a large capacity heater is installed under the refrigerator compartment side region of the evaporator to maximize the defrosting effect. .

In addition, a groove is formed on the surface of the partition 9 that divides the heat exchange area of the evaporator 4 so as to form a groove for forming a turbulent layer for cold air flowing along the surface of the evaporator 4. Improve heat exchange efficiency on the surface.

5 is a perspective view illustrating a case in which the refrigerator structure according to the first embodiment of the present invention is applied to a top mount refrigerator.

In this case, the configuration according to the above-described embodiment is applied to the top mount refrigerator, and the positions of the freezer compartment 1 and the refrigerating compartment 2 and the length of the cooling flow path are different from the side by side refrigerator. , Since the rest of the configuration and operation is the same as the side-by-side refrigerator, detailed description thereof will be omitted.

That is, the top-mounted refrigerator of the independent cooling type configured as described above also has the freezing compartment side cold air and the refrigerating compartment cold air as described above with independent circulation structure, and the effects caused by the side-by-side according to the above-described embodiment are also described.
