Description

Refrigerator {refrigerator}

The present invention relates to a refrigerator, and more particularly, to an independent cooling type 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 front surface of the evaporator (4) is formed with a cold air flow path (10) by the inner plate 7 for partitioning the interior space of the freezer compartment and the space in which the evaporator (4) is installed. In addition, a plurality of cold air outlets 11 are formed in the inner plate 7 and communicate with the freezer compartment, and a cold air inlet in which hot air is introduced into the evaporator 4 while circulating the freezer compartment under the inner plate 7. 13 is formed, the 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 partially distributed on the cold air passage 10 at the freezing compartment side and flows into the refrigerating compartment 2. 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.

Still another object of the present invention is to provide a refrigerator capable of maximizing the high volume of the refrigerator while achieving the above objects.

In order to achieve the above object, the present invention provides a freezer compartment, a refrigerating compartment installed adjacent thereto, a barrier separating the freezer compartment and the refrigerating compartment, an evaporator installed at the barrier to constitute a refrigerating cycle, and a heat exchange area of the evaporator. A split plate divided into two parts, a cold air flow path for a freezer compartment formed in the barrier to send the cold air of one region divided by the separator plate in the cold air that has been exchanged into the evaporator to the freezer compartment, and the cold air that has flowed into the evaporator and heat exchanged A cold air flow path for a cold compartment formed in the barrier to send the cold air in the other region divided by the separating plate to the cold compartment, and a blower fan provided in each of the freezer cold air passage and the cold air flow passage for the cold compartment to forcibly circulate the cold air into each compartment. There is provided a refrigerator characterized in that it comprises a.

The cold air flow path for the freezer compartment and the cold air flow passage for the refrigerating compartment are connected to each other, and a damper is installed on the flow path connected to each other.

The evaporator is characterized by applying a thin heat exchanger of the straight (straight) type.

And, the blowing fan is installed in the barrier is characterized in that the sirocco fan.

Hereinafter, with reference to the accompanying drawings of the present invention will be described in detail an embodiment of the present invention. Before the description, detailed descriptions of components overlapping with those described in the related art will be omitted.

3 is a perspective view illustrating a refrigerator structure of the present invention, and FIG. 4 is a cross-sectional view of the main part of FIG. 3, and is a cross-sectional view taken along line III-III of FIG. 3 at a lower position of the blower fan. FIG. It is a reference figure for demonstrating the structure of a refrigerator on a refrigeration cycle.

Referring to the drawings, the refrigerator 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 the refrigerating compartment 2, and the barrier 3 Evaporator (4) installed in the refrigeration cycle, a separation plate (9) dividing the heat exchange area of the evaporator (4) into two, and a separation plate (9) of cold air introduced into the evaporator (4) and heat exchanged. A cold air flow path (A) for the freezing compartment formed inside the barrier (3) to send the cold air in one region divided by the into the freezing compartment (1), and the separator plate (9) of the cold air introduced into the evaporator (4) and heat exchanged. A cold air flow passage (B) for the refrigerating compartment, a cold air flow passage (A) for the freezer compartment, and a cold air flow passage (B) for the refrigerating compartment, which is formed inside the barrier (3) so as to send the cold air in the other region divided by) to the refrigerating compartment (2). And blower fans 105 and 205 for forcibly circulating cold air into the refrigerator.

At this time, 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 is preferably installed on the flow path (C) connected to each other, it is shown in Figure 3 and 4 in the drawings. Although not shown because it is difficult to be placed, referring to FIG. 5, the installation positions of FIGS. 3 and 4 for the cold air passage A for the freezer compartment and the cold air passage B for the refrigerating compartment, the connection passage C, the damper 8, and the like. And the constitution is to be sufficiently inferred.

And all the said evaporators 4 apply a well-known straight type thin heat exchanger.

On the other hand, it is preferable that a sirocco fan is applied to the blowing fans 105 and 205 provided on each of the cold air flow paths A and B of the barrier 3. It is a plate shape which bisects the heat exchange area | region of the evaporator 4 provided in ().

Referring to the specific form and operation of the side-by-side refrigerator of the present invention having such a configuration as follows.

3 and 4, the independent cooling refrigerator according to the first embodiment of the present invention includes a freezer compartment 1 on the left side and a freezer compartment 2 on the right side of the barrier 3. The barrier 3 is provided with a freezer cold air passage A for supplying and circulating cold air to the freezer compartment side and a cold air passage B for the refrigerating compartment for supplying and circulating cold air to the refrigerating compartment side.

At this time, the freezer compartment cold air flow path (A) and the freezer compartment cold air flow path (B) is separated by a heat exchange area for two minutes by the separator plate 9 and is connected to the evaporator 4 constituting the refrigeration cycle. As shown in FIG. 5, the evaporator 4 forms a refrigerating cycle together with the compressor 30, the condenser 40, and the expansion valve 50.

On the other hand, in the barrier 3, blower fans 105 and 205 for blowing cold air, which are separated by the separating plate 9 and passed through the evaporator 4, to the freezing chamber 1 and the refrigerating chamber 2, are provided for the freezing chamber cold air. Bars are provided in the flow path (A) and the cold air flow path (B) for the refrigerating chamber, respectively, and it is preferable to apply a sirocco fan, which is a centrifugal fan, to the blowing fans 105 and 205. 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 freezer compartment cold air flows into the freezer compartment side heat exchange area of the evaporator 4 through the cold air inlet 103 formed under the barrier 3 and is heat exchanged, and then flows through the freezer compartment side cold air flow path A to allow the barrier 3 to flow. It exits through the cold air discharge port 100 of the rear upper side, and is discharged to the freezer compartment 1 through the cold air discharge port 101 formed along the height direction in the freezer compartment side partition 7.

In addition, the cold air of the refrigerating compartment 2 flows into the refrigerating compartment side heat exchange area of the evaporator 4 through the cold air inlet 203 formed under the barrier 3 and is heat-exchanged, and then refrigerates through the cold air outlet formed on the barrier 3. It is discharged to (2).

That is, referring to FIG. 5, the refrigerator of the present invention includes the evaporator installed in the barrier 3 to the cold air flow path A and the refrigerating chamber 2, which are supplied to the heat exchange area and the freezing chamber 1 around the separator 9. The cold air flow path B supplied is bisected.

The freezer compartment cold air flow path A and the refrigerating compartment cold air flow path B are connected to each other, and a damper 8 is provided on the flow path C connected to each other. By opening the damper 8 in a state where the blowing fan is turned off, condensing cold air toward an unsatisfactory temperature in the refrigerator can satisfy the unsatisfactory temperature in a short time. On the other hand, the cold air flow path for the freezer compartment (A) and the cold air flow path (B) for the refrigerating chamber, the flow path (C) to which they are connected to each other, and the damper (8) installed on the connection flow path (C), etc. are mainly shown in Figs. Reference will be made to reference.

Operation of the independent cooling method refrigerator of the present invention configured as described above is as follows.

First, when the heat exchange environment is formed in the evaporator 4 by the operation of the compressor 30, the freezing chamber blowing fan 105 and the refrigerating chamber blowing fan 205 installed on the freezing chamber cold air flow path A inside the barrier 3. Each will force the cold air in the oven. At this time, the cold air circulating in the freezer compartment 1 is introduced through the cold air intake port 103 and some of the cold air is separated by the separating plate 9 to pass through one region of the evaporator 4, and one region of the evaporator Heat exchanges over time. Then, the cold air that has been heat-exchanged while passing through one side region of the evaporator exits through the cold air outlet 100 at the upper rear side of the barrier 3, and then continues to flow to the freezer compartment partition 7 at regular intervals along the height direction. The circulation process discharged to the freezing chamber 1 through each of the formed cold air discharge ports 101 is repeated.

The cold air circulating in the refrigerating compartment 2 flows through the cold air inlet 203 formed in the barrier 3 and passes through the other region of the evaporator 4 separated by the separator 9. 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 located in the refrigerating chamber side 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, the independent cooling refrigerator according to the present invention separates the cold air by dividing the heat exchange area of the evaporator 4 into two minutes, and installs blower fans 105 and 205 independently controlled in each cold air flow path (A) and (B). By cooling the freezer compartment 1 and the refrigerating compartment 2 independently, the cooling efficiency can be improved and the power consumption can be reduced. 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 and the blower fan should be operated to lower the temperature in the refrigerator that 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, but the refrigerator of the present invention independently cools the freezing compartment 1 and the refrigerating compartment 2, and when one of the first satisfactory conditions is satisfied, the damper 8 is operated by turning off the high-side blower fan whose temperature is satisfied. As the internal high temperature cold air can be concentrated toward the unsatisfactory internal temperature, unnecessary power consumption can be reduced.

In addition, since the refrigerator of the present invention independently cools the freezing compartment 1 and the refrigerating compartment 2, the amount of cold air distributed to the refrigerating compartment 2 after passing through an evaporator in the related art is relatively lower than that of the freezer compartment 1. The problem of low cooling rate is solved.

In addition, the refrigerator of the present invention can maximize the internal volume of the freezer compartment 1 unlike the conventional one installed on the freezer compartment side due to the evaporator 4 installed on the barrier 3. That is, according to the present invention, instead of deleting the existing evaporator installed on the freezer compartment side, by installing the evaporator 4 in the barrier 3 portion of the refrigerator, the contents of the freezer compartment without damaging the contents of the refrigerating compartment 2. You can maximize your enemies.

In addition, according to the present invention, since the cold air passages circulating in the freezing compartment 1 and the refrigerating compartment 2 can be separately separated, the smells of 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, since the cold flow from the freezer compartment and the cold air flow from the refrigerating compartment do not meet at the inlet side of the evaporator, a phenomenon in which frost is easily generated due to the temperature difference is prevented, thereby increasing the defrost cycle.

In other words, the refrigerator of the independent cooling method of the present invention by installing one evaporator and two fans in the barrier and separating the cold air flow path to ensure that the freezer compartment cold side and the cold compartment side cold air have independent circulation structure, as well as the cold air to either side It can be concentrated in the interior can reduce the power consumption, unlike the existing structure in which the evaporator is installed in the freezer compartment can maximize the interior volume of the freezer (1).

So far, the present invention has been described with reference to preferred embodiments thereof, and one of ordinary skill in the art to which the present invention pertains may implement the modified embodiment within the essential technical scope of the present invention. Here, the essential technical scope of the present invention is shown in the claims, and the modified forms within the equivalent range will be construed as being included in the present invention.

The independent cooling refrigerator according to the present invention provides a wide variety of effects as follows.

First, according to the present invention, the freezer compartment and the refrigerating compartment can be cooled independently, and either side can change the flow path when satisfied first, thereby concentrating the cold air in the unsatisfactory store, thereby improving cooling efficiency and reducing unnecessary power consumption. Can be reduced.

Second, according to the present invention is provided with a blower fan for forced supply of cold air to the refrigerating compartment, it is possible to increase the amount of cold air flowing into the refrigerating compartment can improve the cooling rate for the refrigerating compartment.

Third, the refrigerator of the present invention can maximize the high volume of the freezer compartment because the evaporator is installed in the barrier partitioning the freezer compartment and the refrigerating compartment.

On the other hand, the refrigerator of the present invention has an effect that the defrost cycle is increased because frost does not easily occur since the cold flow from the freezer compartment and the cold air flow from the refrigerating chamber do not meet at the inlet side of the evaporator.

Fifth, according to the present invention, since the cold air passages circulating the freezing compartment and the refrigerating compartment are separately separated, the smells of the foods stored in the freezing compartment and the refrigerating compartment may be prevented from affecting each other.
