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, with reference to the accompanying drawings will be described the structure and operation of a typical side-by-side refrigerator.

First, as shown in FIG. 1, the refrigerator includes a freezer compartment 1 in which most of the cold air heat exchanged by the evaporator 4 is introduced to maintain an internal temperature of about −18 ° C., and the evaporator 4. Some of the heat exchanged by the cold air is introduced into the refrigerating chamber that maintains the internal temperature of about 0 ~ 7 ℃.

At this time, the freezer compartment 1 and the refrigerating compartment 2 are partitioned by a barrier 3, and the cold air communication port 3a is provided in the upper portion of the rear side of the barrier 3 so that the cold air heat exchanged by the evaporator 4 is supplied to the refrigerating compartment. Is provided, and cold air communication ports 3b are formed at the lower inner side of the barrier 3 so as to circulate the refrigerating compartment 2 and allow the hot air to flow back into the freezing compartment 1. In addition, a damper (not shown) for controlling cold air introduced into the refrigerating compartment 2 is provided inside the cold air communication port 3a through which the cold air is supplied to the refrigerating compartment.

And, as shown in Figure 2a, the upper part of the evaporator (4) is provided with a blowing fan 6 for forcibly circulating the cold air cooled through the evaporator to the freezing chamber (1) and a motor for driving the blowing fan. The cold air flow path 10 is formed on the front surface of the evaporator 4 by a partition plate 7 that divides the internal space of the freezer compartment and the space in which the evaporator 4 is installed.

At this time, the partition plate (7) is a two-layer plate structure consisting of a front plate (7a) and the back plate (7b), the cold air flow path 10 is formed in the middle.

In addition, a plurality of cold air discharge openings 11 communicating with the freezing chamber are formed in the front plate 7a of the partition plate 7, and the cold air heated at a high temperature while circulating the freezer compartment under the front plate 7a of the partition plate 7. The cold air inlet 13, which flows back into the evaporator 4, is formed, and a machine chamber 5 is provided below the rear surface of the freezing chamber 1.

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 to the cold air passage 10 on the freezer compartment side by the operation of the blower fan 6. Subsequently, a part of the cold air flows into the freezing chamber 1 through the cold air discharge port 11, and a part of the cold air flows into the refrigerating chamber 2 through the cold air cold air communication port 3a. Thereafter, the cold air, which has been heated while circulating in the freezing chamber 1 and the refrigerating chamber 2, is introduced into the evaporator 4 through the suction port 13 to form a cold air circulation structure in which heat is exchanged.

However, the conventional refrigerator has a structure in which the evaporator 4 is provided only at the freezing compartment side, and the cold air heat-exchanged through the evaporator 4 is distributed and introduced into some refrigerating compartment 2 on the cold air passage 10 at the freezing compartment side. Therefore, there were the following problems.

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 results in unnecessary consumption 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.

In addition, the refrigerator having the conventional structure has a disadvantage that the high internal volume of the freezer compartment is reduced due to the thickness of the evaporator 4 installed on the rear wall of the freezer compartment 1, resulting in inefficient use of space.

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.

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 and 4, and FIGS. 11A and 11B.

3 is a perspective view illustrating a refrigerator structure according to a first embodiment of the present invention, and FIG. 4 is a cross-sectional view of FIG. 3.

11A and 11B are reference diagrams for explaining the refrigerator structure according to the first embodiment on a refrigerating cycle, and FIG. 11A is a configuration diagram when the evaporators are connected in series, and FIG. 11B when the evaporators are connected in parallel. The configuration diagram.

Referring to the drawings, the refrigerator according to the first embodiment of the present invention includes a freezer compartment 1, a refrigerating compartment 2 installed adjacent thereto, and a barrier 3 separating the freezer compartment 1 and the refrigerating compartment 2. And a freezer compartment evaporator 4a provided at the side of the freezer compartment constituting a freezer cycle, a refrigerator compartment evaporator 4b provided at the barrier 3 to constitute a freezer cycle, and the freezer compartment evaporator 4a. A cold air flow path (A) for a freezing compartment for sending the introduced and heat-exchanged cold air to the freezing compartment (1), and formed in the barrier (3) to send the heat exchanged cold air to the refrigerating compartment (2) flowing into the refrigerator compartment evaporator (4b). And a cooling fan 105a and 205 which are respectively provided in the refrigerating chamber cold air flow path B and the freezing chamber cold air flow path A and the refrigerating chamber cold air flow path B, for forcibly circulating cold air into each chamber. do.

At this time, the freezer compartment evaporator 4a and the refrigerator compartment evaporator 4b are connected in series or in parallel.

In addition, the freezing chamber cold air flow path (A) and the refrigerating chamber cold air flow path (B) is connected to each other, it is preferable that the damper 8 is installed on the flow path (C) connected to each other.

The freezer evaporator 4a and the refrigerating chamber evaporator 4b both use a well-known straight type thin heat exchanger.

On the other hand, it is preferable that the sirocco fan is applied to the blowing fan 205 installed in the barrier 3.

The specific form and operation of the side-by-side refrigerator according to the first embodiment of the present invention having such a configuration will be described below.

3 and 4, the independent cooling refrigerator according to the first embodiment of the present invention is provided with a freezer compartment 1 on the left side and a refrigerator compartment 2 on the right side with respect to the barrier 3. The freezer compartment (1) side is provided with a freezer cold air flow path (A) for supplying and circulating cold air to the freezer compartment side, and inside the barrier (3) cold air passage for refrigeration room (B) for supplying and circulating cold air to the refrigerating compartment side. Is provided.

At this time, the separated freezing air flow path (A) for the freezing compartment and the freezing air flow path (B) for the refrigerating compartment are provided with a freezing compartment evaporator 4a and a refrigerating compartment evaporator 4b constituting the refrigerating cycle, which are shown in FIGS. 11A and 11B. As shown in the figure, the compressor 30, the condenser 40, and the expansion valve 50 are configured together with the refrigeration cycle.

That is, the freezer compartment evaporator 4a is provided on the freezer compartment side, and the freezer compartment evaporator 4b is installed on the barrier 3.

In the partition plate 7 constituting the cold air flow path A for the freezer compartment, a cold air discharge port 101 and a cold air intake port 103 are formed toward the freezer compartment 1, respectively. Cold air discharge ports 201 and cold air suction ports 203 are formed, respectively.

In addition, a blower fan 105a is installed on the freezing chamber side for forced circulation of cold air, and an axial fan is applied as the blower fan. Therefore, the freezer compartment cold air flows into the freezer compartment evaporator 4a through the cold air inlet 103 at the lower side of the partition plate 7 to be heat exchanged, and then flows through the freezer compartment cold air flow path A to the partition plate 7. It is discharged to the freezing chamber 1 through the provided cold air discharge port 101.

On the other hand, the barrier 3 is provided with a blowing fan 205 for blowing cold air that has passed through the refrigerating chamber evaporator 4b to the refrigerating chamber 2, wherein the blowing fan 205 is a sirocco fan which is a centrifugal fan. It is preferable to apply. The reason why the sirocco fan, which is a centrifugal fan, is used as the blowing fan as described above is that the narrow width of the barrier 3 is considered.

Therefore, the cold air of the refrigerating compartment 2 flows into the refrigerating compartment evaporator 4b through the cold air inlet formed under the barrier 3 and is heat-exchanged, and then is discharged to the refrigerating compartment 2 through the cold air outlet formed on the barrier 3. .

That is, referring to FIGS. 11A and 11B, in the refrigerator according to the first embodiment of the present invention, the freezing compartment 1 and the refrigerating compartment 2 are separated from each other around the barrier 3 and supplied to the freezing compartment 1. The cold air passage A and the cold air passage B supplied to the refrigerating chamber 2 are separated from each other. At this time, the freezer compartment evaporator 4a is installed at the freezer compartment 1 side, and the freezer compartment evaporator 4b is separately installed at the barrier 3 to constitute a freezer cycle.

In this case, in the independent cooling type refrigerator according to the first embodiment of the present invention, the freezer compartment evaporator 4a provided at the freezer compartment side and the freezer compartment evaporator provided at the barrier 3 as shown in FIG. Or in parallel as in FIG. 11B.

Therefore, when the two evaporators are connected in series, the refrigerant circulating in the refrigerating cycle is first supplied to the freezer compartment evaporator 4a and then to the refrigerating compartment evaporator 4b installed in the barrier 3, in each evaporator. The heat exchange amount varies depending on the refrigerant amount and the heat exchange area.

On the other hand, when the two evaporators are connected in parallel, the heat exchange amount is controlled differently by the distribution amount of the refrigerant.

When the freezer compartment cold air flow path (A) and the refrigerating compartment cold air flow path (B) are connected to each other and the damper 8 is provided on the flow path (C) connected to each other, when the temperature in any one of the refrigerators is satisfied, By opening the damper 8 and concentrating the cold air toward the unsatisfactory temperature, the unsatisfactory inner temperature can be satisfied in a short time.

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

First, when a heat exchange environment is formed in the evaporators 4a and 4b by the operation of the compressor 30, the axial flow fan and the refrigerating chamber blowing fan 205, which are the freezing chamber blowing fans 105a installed on the freezing chamber 1 side, are provided. Each of the sirocco fans forces the cold air in the oven to circulate. At this time, the cold air circulating in the freezer compartment 1 flows through the cold air inlet 103 and passes through the evaporator 4a to be heat exchanged, and is then discharged to the freezer compartment 1 through the cold air outlet 101. Will repeat.

The cold air circulating in the refrigerating compartment 2 flows in through the cold air inlet 203 formed in the barrier 3 and passes through the evaporator 4b to exchange heat. The cold air heat-exchanged in this way repeats the circulation process discharged to the refrigerating chamber 2 through the cold air discharge port 201 of the barrier (3).

On the other hand, as 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, 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.

Therefore, in the independent cooling refrigerator according to the first embodiment of the present invention, as the freezing chamber 1 and the refrigerating chamber 2 are independently cooled by two evaporators, it is possible to improve the cooling efficiency and reduce the power consumption. 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 maximize the contents of the refrigerator.

That is, in the refrigerator having a conventional structure, the compressor 30 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. However, the refrigerator of the present invention independently cools the freezer compartment (1) and the refrigerating compartment (2), and when one of the first satisfies the damper (8) in a state in which the high inner blower fan is turned off. By operating, the satisfactory high internal cold air can be concentrated toward the unsatisfactory internal temperature, thereby reducing unnecessary power consumption.

In addition, since the refrigerator according to the present embodiment independently cools the freezing compartment 1 and the refrigerating compartment 2, the amount of cold air that is distributed to the refrigerating compartment 2 after passing through an evaporator in the related art is relatively low, and thus the freezing compartment 1 is relatively low. Compared to the problem that the cooling rate is lowered.

In addition, the refrigerator according to the present embodiment can reduce the thickness of the evaporator installed on the freezer compartment side by installing the refrigerating compartment evaporator 4b on the barrier 3, thereby increasing the internal volume of the freezer compartment 1. .

That is, according to the present embodiment, the small evaporator 4a dedicated to the freezer compartment 1 is installed in the existing position while replacing the existing evaporator with two evaporators, and the small evaporator dedicated to the refrigerating compartment in the barrier 3 portion of the refrigerator. By installing (4b), it is possible to maximize the contents of the freezer compartment without causing any loss of the contents of the refrigerator 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.
