Description

Complex module and refrigerator including the same

The present invention relates to a binder phase module and a refrigerator including the same for minimizing condensation of an evaporator generated in a process of performing a refrigerant cycle.

In general, the refrigerant cycle has been applied to a variety of products for a variety of purposes, such as air conditioning, refrigeration, refrigeration. For example, products, such as a refrigerator and an air conditioner, are mentioned.

Based on the basic principle of the refrigerant cycle in which the refrigerant circulates through compression, condensation, expander, and evaporator and repeats the compression, condensation, expansion, and evaporation process, the refrigerant absorbs heat from the outside when the refrigerant evaporates. It is applied to the cooling of the room or the cooling of the room. That is, the cooling of the food or the cooling of the room may be performed by supplying the cooled air to the food storage space or the indoor space by taking heat into the refrigerant while the refrigerant evaporates.

However, in the process of cooling the air by the refrigerant in the evaporator, a phenomenon occurs in which moisture contained in the air is frosted on the surface of the evaporator. At this time, the condensed water is frozen in the outdoor unit of the air conditioner when the refrigerator or the heating unit has a problem of sharply lowering the heat exchange efficiency.

In order to solve this problem, Korean Patent Laid-Open Publication No. 2011-0006996 has an attempt to defrost by heating an evaporator with a heater by providing a heater for defrosting an evaporator of a refrigerator.

However, in this case, the installation space for accommodating the heater is necessary, so that the volume of the product is inevitably increased, and since the heat of the heater is applied in one direction, uniform defrosting of the evaporator is difficult and additional power consumption is generated. .

In addition, since the normal operation of the device in which the evaporator is used, such as a refrigerator, an air conditioner during defrosting is interrupted, that is, the continuous operation is not possible, there is a problem that the function of the product is significantly reduced. In particular, in the case of the refrigerator, even if the refrigerator is converted to normal operation after defrosting, heat generated in the defrosting process is introduced into the refrigerator, thereby increasing the load of the refrigerator at the end of the defrosting.

The present invention is to solve the above-mentioned problems of the prior art, and to provide a refrigerator comprising a composite module and the like that can minimize the phenomenon of frost on the evaporator.

In addition, the present invention is to provide a refrigerator module comprising a complex-like module capable of defrosting while performing the original function of the refrigerant cycle normally.

In addition, it is possible to provide a refrigerator and a refrigerator comprising a complex module that can continuously operate the refrigerator to maintain the performance of the product.

Technical problems to be achieved by the present invention are not limited to the above-mentioned technical problems, and other technical problems not mentioned above will be clearly understood by those skilled in the art from the following description. Could be.

The complex phase module according to the present invention, which is proposed as described above, passes through the evaporator to exchange heat with the refrigerant so as to minimize the phenomenon of frost on the evaporator connected to the compressor, the condenser and the expander to perform the refrigerant cycle. It is characterized in that installed on the upstream side of the evaporator with a lower temperature than the air on the basis of the flow of air.

In addition, the refrigerator including the complex-like module according to the present invention includes a body in which at least one of a refrigerating chamber and a freezing chamber is formed; A compressor, a condenser, an expander and an evaporator installed in the main body so that a refrigerant cycle can be performed to cool the food stored in at least one of the refrigerating compartment and the freezing compartment; A circulation passage guiding circulating air for cooling the food to circulate the refrigerating compartment and the freezing compartment and the evaporator; A landing module installed at a lower temperature than circulating air on an upstream side of the evaporator so as to minimize frost on the evaporator; And defrosting means provided in the main body to defrost the complexing module.

As described above, according to the complex-type module and the refrigerator including the same according to the present invention, there is an advantage of minimizing the phenomenon of frost on the evaporator.

In addition, since defrosting may be performed while the original function of the refrigerant cycle, such as refrigeration and freezing, may be performed normally, there is an advantage of eliminating inconvenience, such as the need to stop the refrigerant cycle operation for defrosting.

In addition, it is possible to minimize the heat load generated during defrosting, there is an advantage that can significantly reduce the power consumption.

1 and 4, the complex phase module 60 according to the present invention is connected to the compressor 20, the condenser 30, the expander 40 is frosted on the evaporator 50 to perform a refrigerant cycle In order to minimize the phenomenon, the temperature is installed at a temperature lower than that of the air on the upstream side of the evaporator 50 based on the flow of air passing through the evaporator 50 to exchange heat with the refrigerant.

In more detail, the refrigerant cycle may be applied to various products such as a refrigerator and an air conditioner. However, in the present embodiment will be described mainly applied to the refrigerator 10.

In order for the refrigerant cycle to be performed, a configuration such as a compressor 20, a condenser 30, an expander 40, and an evaporator 50 is required so that the refrigerant may be compressed, condensed, expanded, and evaporated. That is, the refrigerant is compressed to high temperature and high pressure while passing through the compressor 20 and then introduced into the condenser 30, cooled to low temperature and high pressure while passing through the condenser 30, and then introduced into the expander 40. Passing through the expander 40 is expanded to a low temperature low pressure and then introduced to the evaporator 50. The refrigerant is heated in a state of high temperature and low pressure while passing through the evaporator 50 and then circulated in such a manner as to flow back into the compressor 20, repeatedly performing a refrigerant cycle such as compression, condensation, expansion, and evaporation.

In this case, the refrigerant absorbs heat by exchanging heat with another material such as, for example, air while the refrigerant passes through the evaporator 50. That is, in the evaporator 50, the air may be cooled by the refrigerant, and the food stored in the refrigerator 10 may be refrigerated or frozen by using the air cooled by the refrigerant.

Meanwhile, the refrigerator 10 cools the main body 11 in which at least one of the refrigerating chamber 100 and the freezing chamber 100 is formed, and food stored in at least one of the refrigerating chamber 100 and the freezing chamber 100. In order to perform a refrigerant cycle, the compressor 20, the condenser 30, the expander 40, and the evaporator 50 installed in the main body 11 and the circulating air for cooling food are stored in the refrigerating chamber ( 100) and the circulation passage 70 for circulating the freezer compartment 100 and the evaporator 50, and the frost flow on the circulation passage 70 so as to minimize the phenomenon of frost on the evaporator 50; And a defrosting means provided in the main body 11 to defrost the complexing module 60, which is installed at a temperature lower than the circulating air on an upstream side of the evaporator 50. .

The refrigerating chamber 100 and the freezing chamber 100 may be provided in all or any one according to the type of the refrigerator 10, may be placed in the left and right or up and down directions. In the present embodiment, the refrigerator 10 in which the refrigerating chamber 100 and the freezing chamber 100 are placed to the left and right will be described as an example.

In the main body 11, except for the refrigerating chamber 100 and the freezing chamber 100, an installation space 101 for installing various components for the operation of the refrigerator 10 is formed. In the installation space 101, the compressor 20, the condenser 30, the expander 40, and the evaporator 50, which perform a refrigerant cycle, are installed, and the air of the refrigerating chamber 100 and the freezing chamber 100 is provided. Fans, ducts, etc. for circulating to be cooled by the evaporator 50 may be installed.

The complex phase module 60 may be installed between the expander 40 and the evaporator 50 on the refrigerant cycle. That is, the refrigerant passing through the expander 40 may be configured to flow into the evaporator 50 after passing through the complexing module 60.

Thus, the complex phase module 60 may have a lower temperature than the evaporator 50. In addition, the fin spacing L2 of the landing module 60 is formed to be narrower than the fin spacing L1 of the evaporator 50. As the complex phase module 60 has a lower temperature and the pin spacing L2 of the complex phase module 60 is narrower, the complex phase module 60 may be relatively smaller than the evaporator 50. There is an effect that can be conceived intensively. On the other hand, as the frost is concentrated on the landing module 60, the frost on the evaporator 50 can be minimized.

In addition, the complex-phase module 60 is positioned on an upstream side of the evaporator 50 based on a flow path through which the circulating air of the refrigerating chamber 100 and the freezing chamber 100 flowing through the evaporator 50 flows. Therefore, the circulating air flowing into the evaporator 50 from the refrigerating chamber 100 and the freezing chamber 100 passes through the complexing module 60 first, while frost is formed on the complexing module 60. Moisture contained in will be removed. As a result, the moisture contained in the circulating air is mostly frosted on the landing module 60, the phenomenon that frost is implanted in the evaporator 50 can be minimized.

The defrosting means includes an air heater 81 installed at one side of the compressor 20 and the condenser 30 so that air can be heated by the compressor 20 and the condenser 30, and the air heater 81. It includes a defrost flow path (82) for guiding the heating air to the complex phase module 60 so that the complex phase module 60 is heated by the heated air heated in the).

In the air heater 81, the air is heated using heat generated during operation of the compressor 20 and heat released during the condensation of the refrigerant in the condenser 30. In addition, since the heated air heated in the air heater 81 flows into the complex-type module 60 through the defrosting flow path 82, frost formed on the complex-type module 60 may be removed.

The partition 74 divides the circulation passage 70 into a second space portion 72 in which the first space portion 71 and the second idea portion 62 are located. It is provided. Therefore, the circulating air flowing along the circulation flow path 70 is formed by the partition portion 74 so as to correspond to the first space portion 71 and the first space portion 71 and the second land portion 62. It is separated into the second space portion 72 corresponding to the flow.

In addition, the first space portion 71 and the second space portion 72 at the point where the circulation passage 70 starts to be separated into the first space portion 71 and the second space portion 72. A flow control unit 73 is provided for selectively blocking the flow of circulating air toward. Thus, by switching the flow control unit 73, the air flowing through the circulation passage 70 can selectively pass through any one of the first and second landing portion 61 and 62. Make sure

Therefore, the refrigerant control unit 90 blocks the flow of the refrigerant toward the defrost of the first and

second landing units

That is, one ends of the first defrost duct 821 and the second defrost duct 822 are connected to the main defrost duct 820 and the other of the first defrost duct 821 and the second defrost duct 822. The end part communicates with the said 1st space part 71 and the 2nd space part 72, respectively.

In addition, heating air of the main defrost duct 820 is connected to the first defrost duct 821 at a point where the main defrost duct 820, the first defrost duct 821, and the second defrost duct 822 are simultaneously connected. And a defrosting control unit 83 for selectively flowing one of the second defrost ducts 822.

In addition, the discharge passage 84 is installed to selectively communicate with any one of the first space portion 71 and the second space portion 72. A discharge port 704 is formed at one surface of the circulation flow path 70 to allow the discharge flow path 84 to penetrate, and the discharge flow path 84 passes through the discharge port 704 to the inside of the circulation flow path 70. It is inserted through. The outlet 704 extends to cover the first space portion 71 and the second space portion 72 at the same time, and the discharge passage 84 slides along the outlet 704. The first space 71 and the second space 72 may be selectively communicated with. In addition, the outlet 704 may be further provided with a shielding portion 705 for selectively shielding the remaining portion of the outlet 704 that is not shielded by the discharge passage (84).

At this time, one surface of the exhaust passage 84 inserted into the circulation passage 70 toward the landing module 60, the air passing through the landing module 60 is the discharge passage ( 84) so that it can be discharged.

In addition, by the remaining portion of the discharge passage 84 except for one surface, the air passing through the cultivation unit (61, 62) being defrosted from the ignition module (60) can be blocked from entering the evaporator (50). Can be. That is, when the first landing portion 61 is defrosted, the discharge passage 84 is positioned in the first space 71 so that the first defrost duct 821 and the discharge passage 84 communicate with each other. The second defrosting duct 822 and the discharge passage 84 communicate with each other when the discharge passage 84 is positioned in the second space portion 72 when the second landing portion 62 is defrosted.

On the other hand, during the defrosting of the first implantation unit 61, the flow of the circulating air through the first space portion 71 is blocked by the flow control unit 73 and the second space portion ( The second space portion 72 is opened to allow the circulation air to flow through 72, and heated air flows to the first space portion 71 by the defrost control unit 83. The flow of the heating air toward the two space portions 72 is cut off.

In the defrost of the second implantation unit 62, the flow control unit 73 blocks the flow of the circulating air through the second space unit 72 and the first space unit 71. The first space 71 is opened to allow the circulation air to flow therethrough, and the flow of heating air toward the first space 71 is blocked by the defrost control unit 83, and the first space 71 is opened. The heating air flows toward the two space portions 72.

second landing parts

61 and 62 is performed alternately at regular intervals. The signal may be preset.

According to the present invention, there is an advantage of minimizing the phenomenon of frost on the evaporator 50. While the air passing through the expander 40 passes through the landing bed module 60 before reaching the evaporator 50, moisture contained in the air is condensed or condensed into the frost. Therefore, the phenomenon of frost on the evaporator 50 can be minimized.

In addition, since defrosting may be performed while the original function of the refrigerant cycle, such as refrigeration and freezing, may be performed normally, there is an advantage of eliminating inconvenience, such as the need to stop the refrigerant cycle operation for defrosting.
