Description

Machine room assembly and refrigerator having the same

The present invention relates to a refrigerator, and more particularly, to a machine room assembly in which a control module is installed, and a refrigerator including the machine room assembly.

In general, refrigerators are home appliances that allow low-temperature storage of food in an internal storage space that is shielded by a door. To this end, the refrigerator is configured to store the stored food in an optimal state by cooling the inside of the storage space using cold air generated through heat exchange with the refrigerant circulating through the refrigeration cycle.

Recently, refrigerators are gradually becoming multifunctional in accordance with changes in dietary life and the trend of high-end products, and refrigerators having various structures and convenience devices that enable users' convenience and internal space to be efficiently used are being released. In particular, as consumption and preference of alcoholic beverages such as wine and champagne increase, refrigerators suitable for storage according to types of alcoholic beverages and refrigerators for storing aged foods such as kimchi for a long time are being developed.

In addition, recently, the exterior design of the refrigerator has been made to harmonize with the furniture in the space where the refrigerator is installed.For example, a built-in refrigerator has been in the spotlight in terms of interior because the exposed part is minimized. have. They serve to assist existing refrigerators and can store frequently used foods in the interior of the kitchen furniture, thereby enhancing the convenience of use.

These built-in refrigerators can also be used in the recently widely applied Island Kitchen (Kitchen Island).The island-type kitchen furniture, which is a worktop independent from the sink, has high convenience, but it is difficult to apply the refrigerator as a built-in type because the overall height is low. have.

In particular, since refrigerators require not only a storage for storing food, but also a machine room for realizing the refrigeration cycle and a place for installing a control unit for controlling the refrigerator, it is difficult to downsize the refrigerator. It can fall.

In order to solve this problem, it is possible to consider installing other devices as well as parts for implementing the refrigeration cycle inside the machine room. For example, a control unit may be installed together in a machine room, or a device for communication may be installed. The Korean Utility Model 1999-0032472 discloses the installation of a PCB on the side wall of the machine room of a refrigerator, and the Republic of Korea Utility Model 20-0256427 discloses the installation of an electric box on the side wall of the machine room.

However, these conventional techniques can save the machine room of parts because the control unit (PCB, electrical box) is built inside the machine room, but the control unit is maintained because it is installed inside the machine room where the compressor and heat exchanger are installed, that is, near the rear of the refrigerator. Difficult to repair

In particular, built-in refrigerators are often installed with the rear obstructed, so if the control unit is located inside the machine room close to the rear of the refrigerator, it is inconvenient to completely separate the entire refrigerator from the built-in furniture first for maintenance by the control unit. There is this.

In addition, since the refrigerator control unit of the prior art is fixed to the side wall of the machine room with a separate fastener, the control unit can be removed and repaired or replaced only after the fastener is first separated, thereby reducing workability.

In addition, since the control unit of the prior art is installed in a direction erected on the side wall of the refrigerator, it is necessary to fix the circuit board constituting the control unit to the case to prevent shaking. Since it is not revealed, there is a disadvantage that it is difficult to maintain the control unit.

Republic of Korea public utility model 1999-0032472 Republic of Korea Utility Model Registration 20-0256427

The present invention is to solve the problems of the prior art as described above, and an object of the present invention is to install a control module for controlling a refrigerator at a position close to the entrance of a machine room to separate the control module to the front of the refrigerator or It can be installed, but the inflow and outflow of air is not disturbed by the control module.

Another object of the present invention is to accommodate the control module in the machine room in a sliding fastening method without a separate fastener.

Another object of the present invention is to allow the control module to be accommodated in the machine room in a laid-down state.

Another object of the present invention is to prevent vibrations generated by refrigeration cycle implementation devices installed in the machine room from being directly transmitted to the control module even if the control module is installed inside the machine room.

According to the features of the present invention for achieving the object as described above, the present invention provides a machine room frame in which a machine room is inside and an inlet and an outlet capable of inhaling and discharging air are opened respectively in the front of the machine room, and in the machine room. Including a control module to be installed, the control module is disposed adjacent to the front of the machine room to face the inlet or outlet. In this way, a control module as well as devices for implementing the refrigerant cycle can be installed in the machine room to increase space utilization. At this time, the control module can be installed close to the entrance of the machine room and separated to the front of the machine room.

And the control module is installed on the upper part of the machine room adjacent to the outlet. As described above, when the control module is installed above the discharge port, the discharge port is formed between the bottom surface of the control module and the bottom surface of the machine room frame, so that the flow of air discharged through the discharge port may not be disturbed.

The control module has a width smaller than or equal to the width of the outlet so as to be able to enter and exit the outlet.

In addition, an installation rail is provided at an upper portion of the machine room frame in a direction parallel to a direction in which the discharge port is opened, and the control module is assembled to the installation rail to enter and exit the discharge port along the installation rail. The control module can be smoothly in and out of the machine room through an installation rail structure.

A suction and discharge grill having the suction and discharge ports is detachably assembled on the front of the machine room frame, and when the suction and discharge grill is separated from the front of the machine room frame, the front of the control module is exposed to the front of the machine room frame. do. Therefore, it is possible to perform maintenance work of the control module in front of the refrigerator without taking out or removing the entire refrigerator.

In addition, a pair of installation rails spaced apart from each other to be coupled to both sides of the control module extend in parallel, and the control module is slidably assembled between the pair of installation rails. Therefore, simply pushing the control module into the machine room can complete the assembly of the control module.

In addition, the control module is installed parallel to the upper surface of the machine room frame while facing the upper surface of the machine room frame corresponding to the ceiling of the machine room. Accordingly, since the circuit board constituting the control module is stored in a state lying parallel to the inside of the storage case, which is a kind of drawer structure, stable storage is possible without fixing the circuit board with a separate fastener.

In addition, the machine room frame is opened to the top, a cover plate is covered on the top of the machine room frame to shield the machine room, and the control module is installed on the bottom surface of the cover plate. Therefore, even without a separate cover, the bottom of the cover plate shields the upper part of the control module.

And the installation rail includes a first rail installed on a bottom surface of a cover plate covering an upper portion of the machine room frame, and a second rail installed in a direction parallel to the first rail on a bottom surface of the cover plate, and the control module Both side surfaces of are slidably assembled to the first rail and the second rail, respectively. Since the installation rails separated into two can be assembled independently of each other, errors in the manufacturing process can be compensated to some extent.

The first rail and the second rail are composed of a fixing frame fixed to the bottom of the cover plate, and a guide frame connected to the fixing frame and formed with a guide channel through which a side surface of the control module is fitted. The fixing frame allows the installation rail to be securely fixed.

In addition, the control module includes a storage case detachably assembled on an upper portion of the machine room and having a storage space at a center thereof, and a main control board accommodated in the storage space of the storage case and connected to an external component through a wire harness. The main control board may be accommodated in a lying state in a storage case without a separate fastener.

In addition, a guide end assembled to an installation rail protrudes from the storage case of the control module, and the guide ends extend along both side surfaces of the storage case. Through this simple structure, the control module can be easily fixed inside the machine room.

In addition, the guide ends are provided on both sides of the storage case at upper ends closest to the bottom surface of the cover plate covering the machine room. Therefore, the control module can be closely attached to the upper part of the machine room as much as possible.

In addition, the storage case of the control module is opened toward the bottom of the cover plate covering the upper portion of the machine room. Therefore, when the storage case is taken out, the main control board is exposed and maintenance can be performed, but when assembled in the machine room, the cover plate acts as a kind of cover to shield the storage space.

The storage space of the storage case is surrounded by a side surface of a protective wall protruding along the edge of the storage case. The protective wall prevents foreign substances from entering the storage space.

In the storage case of the control module, a storage space in which the main control board is accommodated is at the center, and a wire connection space is formed outside the storage space around the storage space, and between the storage space and the wire connection space. The partition wall protrudes in the. The wire connection space makes it easy to organize the wire harness.

In addition, at least one through hole is opened in the partition wall so that the storage space and the wire connection space are connected to each other through the through hole. Branching of the wire harness may be made more easily through the through hole.

In addition, a connection hole may be penetrated from the storage case of the control module toward the inside of the machine room, so that a part of the wire harness connected to the control module may extend to the outside of the storage case through the connection hole.

The machine room assembly according to the present invention and a refrigerator including the same as described above have the following effects.

In the present invention, a control module as well as devices for implementing a refrigerant cycle may be installed in the machine room to increase space utilization. In this case, the control module may be installed near the entrance of the machine room and separated to the front of the machine room. Therefore, it is not necessary to open the rear of the refrigerator for maintenance of the control module, and the control module can be separated from the front of the refrigerator to repair or replace, thereby improving the maintainability of the control module.

Particularly, if the machine room of the present invention is applied to a built-in refrigerator, this convenience can be further improved because work can be performed in front of the refrigerator without having to take out the entire refrigerator from the installation site.

Further, in the present invention, since the control module is assembled to the machine room assembly in a sliding manner without a separate fastener, not only the installation of the control module but also the disassembly operation can be easily performed. At this time, when the suction and discharge grill that shields the front of the machine room is separated, the control module is exposed to the front, so that the control module is more easily separated.

In addition, in the present invention, the control module is installed above the outlet of the machine room, not the inlet. In a device to which a refrigeration cycle is applied, such as a refrigerator, heat dissipation of the condenser and compressor is important to improve efficiency. Although the control module is installed inside the machine room as described above, suction of outside air for heat dissipation may not be disturbed as much as possible.

In addition, since the circuit board constituting the control module is stored in a state lying parallel to the inside of the storage case, which is a kind of drawer structure, stable storage is possible without fixing the circuit board with a separate fastener.

At this time, since the control module is accommodated in a state lying in parallel in the width direction rather than in the height direction of the machine room, it is possible to secure a left and right installation space corresponding to at least the width direction of the outlet. Accordingly, the area of the circuit board constituting the control module can be sufficiently large, and various functions can be provided in one wide circuit board, and as a result, the structure of the control module can be simplified.

In addition, since the storage case constituting the control module in the present invention has a structure that is open to the top without a separate cover, when the operator separates the control module to the front, the parts of the control module, such as a circuit board, can be checked with the naked eye. Therefore, sufficient visibility can be secured even in a narrow lower space during the maintenance process of the control module.

Further, in the present invention, since the control module is installed on the bottom of the cover plate covering the upper part of the machine room, the lower surface of the cover plate shields the upper part of the control module even without a separate cover. That is, when the control module is installed in the machine room, the cover plate serves as a kind of cover, and thus, foreign substances such as dust can be prevented from entering the control module without a separate cover, thereby reducing the number of parts.

In addition, since a wire connection space is secured around the edge of the storage case constituting the control module of the present invention, it is possible to effectively organize a plurality of wires extending from a circuit board. In particular, there is a high possibility that the wires of a plurality of strands are twisted or interfere with other parts in a narrow machine room. In the present invention, since they can be arranged through a wire connection space, there is an effect of improving the installation convenience of the control module.

In addition, the control module of the present invention is installed on a cover plate covering an upper portion of the machine room, not a frame constituting the machine room. Therefore, it is possible to prevent the vibration generated from a device such as a compressor installed on the floor of the machine room from being directly transmitted to the control module, thereby improving operational reliability of the control module.

Specifically, the connector housing 257 guides the wire harness extending upward from the control module 700 located at the bottom toward the rear side, that is, the rear plate 213.

Next, referring to the beds 330a to 300d, the beds 330a to 300d are installed in the storage space 121 and serve to divide the storage space 121 into several layers. However, the beds 330a to 300d do not divide the storage space 121 of several floors into completely independent spaces, but allow each floor to communicate with each other. To this end, in this embodiment, the beds 330a to 300d have gaps opened in the vertical direction.

These beds (330a to 300d) are formed in a tray structure having a flat plate or a peripheral wall so that food or the like can be seated on the upper surface thereof. And guide rails 122 (refer to FIG. 3) are provided on both side walls (both sides of the inner case 120) of the storage space 121, and both sides of the beds 330a to 300d are provided with the guide rails ( 122), while being moved back and forth, it is configured to be taken out from the storage space 121 in a drawer type. Other various structures not shown may be configured so that the drawer-type take-out of the beds 330a to 300d is achieved.

The bed (330a ~ 300d) is composed of a plurality of the barrier 400 may be located in the middle. The barrier 400 is installed in parallel with the beds 330a to 300d across the storage space 121 and partitions the storage space 121. Unlike the beds 330a to 300d, the barrier 400 divides the storage space 121 into separate spaces. Accordingly, the upper and lower portions of the barrier 400 become different spaces. Accordingly, the upper space and the lower space of the barrier 400 may be independently controlled to have different temperatures.

A display module 800 is installed on the front surface 430 of the barrier 400. The display module 800 is a component provided to display each state of the refrigerator and perform various controls. Each state displayed through the display module 800 may be a temperature in the storage space 121, an operation mode display, or the like.

The display module 800 may be configured to be operated by a touch type, or may be configured to be operated by a button type or a switch type. In this case, the display module 800 may be provided in the cabinet 100 or may be provided in the door assembly 130. However, if the display module 800 is provided in the door assembly 130, the connection structure of various signal lines or power lines is bound to be complicated. In consideration of this, it is more preferable that the display module 800 is provided in the cabinet 100.

Moreover, considering that the viewing window 142 forming the inner portion of the door assembly 130 is made of glass capable of internal viewing, the display module 800 is a barrier 400 installed at an intermediate height of the storage space 121 It is most preferable to install it in front of the.

Next, looking at the grill fan modules 500a and 500b, the grill fan modules 500a and 500b are configured to circulate air in the storage space 121. These grill fan modules 500a and 500b are provided in front of the rear wall of the inner case 120, and after inhaling air from the lower side of the storage space 121, the air is directed upwards in the storage space 121. Is configured to discharge. At this time, the upper and lower sides of the storage space 121 are determined based on the height of the middle side of the storage space 121.

On the other hand, the grill fan module (500a, 500b) may be provided one for each storage space 121, by using one grill fan module (500a, 500b) to control air circulation to all storage spaces (121) It may be configured to do. As shown in FIG. 5, in the embodiment of the present invention, it is assumed that one grill fan module 500a, 500b is provided for each storage space 121. That is, grill pan modules 500a and 500b are installed in the lower storage space 121a and the upper storage space 121b partitioned with respect to the barrier 400, respectively.

Although not shown, the grill fan modules 500a and 500b may include a circulation fan, a shroud, a partition partition, etc., of which the circulation fan is a fan driven to blow air, and air in the axial direction It consists of a centrifugal fan that sucks the air and blows it in the radial direction. In FIG. 5, arrows indicate a flow through which air is circulated in the upper storage space 121 and the lower storage space 121 by each of the grill fan modules 500a and 500b.

Next, the air conditioning module 600 will be described with reference to FIGS. 6 to 9 attached thereto. The air conditioning module 600 is a component for controlling the temperature in the storage space 121 of the inner case 120. The air conditioning module 600 may be formed of an air conditioning apparatus including a compressor 610, a main condenser 620, and evaporators 630a and 630b. That is, the temperature of the air circulating in the storage space 121 can be adjusted by the above-described air conditioner.

The compressor 610 and the main condenser 620 are provided in the machine room 201 in the machine room frame 200. Here, the main condenser 620 is located on the side where air is introduced among both sides divided by the separation partition wall 230 in the machine room frame 200, and the compressor 610 passes through the main condenser 620 It is located in the area through which one air passes. In particular, the compressor 610 is located on the side from which air is discharged.

This structure is such that the air introduced into the machine room 201 of the machine room frame 200 can preferentially pass through the main condenser 620. That is, when the compressor 610 is configured to heat exchange with the main condenser 620 after passing through the compressor 610, considering that the compressor 610 generates a large amount of heat, its heat exchange efficiency may be deteriorated. Accordingly, it is preferable to configure the air to pass through the main condenser 620 before the compressor 610.

In addition, the main condenser 620 is located on the front side (a side adjacent to the open front) in the machine room 201, and the compressor 610 is located on the rear side in the machine room 201 (rear plate 213). Is located on the adjacent side). This structure is to reduce the influence of the high temperature heat of the compressor 610 on the main condenser 620 by dividing the positions of the compressor 610 and the main condenser 620 as much as possible and spaced apart.

In addition, a heat dissipation fan 611 is provided on the air inlet side of the compressor 610 so that air is sucked and discharged into the machine room 201 and radiates the compressor 610. This heat dissipation fan 611 performs a function of virtually blocking the portion where the compressor 610 is located from the air inlet side where the main condenser 620 is located, so that the high temperature heat of the compressor 610 is transmitted to the main condenser 620. You will be able to reduce the impact. To this end, the heat dissipation pad is continuously installed in the separation partition wall 230 described above.

The refrigeration cycle is operated while the refrigerant continuously flows inside each of the components constituting the air conditioning module 600. At this time, each component is connected to a plurality of refrigerant pipes, and the evaporation pipe (L2), side condensation pipes (L4, L6), and front condensation pipe (L8), which will be described below, are also included in the refrigerant pipe.

6 and 7, first, the evaporation tube evaporation pipe L2 is installed in the defrost water tray 240 and is located close to the bottom surface of the defrost water tray 240. The evaporation pipe (L2) is installed to be spaced a predetermined distance from the bottom surface of the defrost water tray 240, and is connected in a zigzag direction as shown in FIG. 6 in order to secure the maximum length. The is a passage through which the high-pressure/high-temperature refrigerant passes by being connected to the refrigerant discharge pipe 610a of the compressor 610 through the main control valve 625, close to the bottom surface of the defrost water tray 240. Since it is disposed, it may serve to evaporate the defrost water accumulated in the defrost water tray 240. Reference numeral L1 denotes a first connection pipe connecting between the main control valve 625 and the evaporation pipe L2.

The evaporation pipe L2 is connected to the main condenser 620, and the first side condensation pipe L4 is connected to the main condenser 620. The first side condensation pipe L4 is provided on the left side of the cabinet 100 based on FIG. 6 and is bent a plurality of times. Referring to FIG. 8, a part of the second connector L3 connecting the main condenser 620 and the first side condensing pipe L4 is shown.

The first side condensing pipe L4 is connected to the second side condensing pipe L6 through a third connection pipe L5 (see FIG. 6) that crosses the machine room 201. The second side condensing pipe L6 has the same shape by forming a pair with the first side condensing pipe L4, but is provided on the right side of the cabinet 100 as shown in FIG. 6. Of course, the second side condensing pipe L6 does not necessarily have the same shape as the first side condensing pipe L4.

The second side condensation pipe L6 is connected to the front condensation pipe L8 through a fourth connection pipe L7. The front condensation pipe L8 is provided on the front surface of the cabinet 100 and is a refrigerant pipe that is bent a plurality of times. In FIG. 6, the front condensing pipe L8 is substantially rectangular, which has a shape corresponding to the front frame 118 described above.

The first side condensing pipe (L4), the second side condensing pipe (L6), and the front condensing pipe (L8) can each perform a function of condensing the refrigerant together with the main condenser 620, Even if a large main condenser 620 cannot be installed in the machine room 201 due to its low and narrow height, this can be supplemented. Accordingly, the first side condensing pipe L4, the second side condensing pipe L6 and the front condensing pipe L8 may also be viewed as a part of the condenser together with the main condenser 620.

In addition, the first side condensing pipe (L4), the second side condensing pipe (L6), and the front condensing pipe (L8) have a structure that surrounds the exterior of the cabinet 100, so the cabinet It can also serve as a kind of hotline to prevent dew from occurring on the surface of (100).

When the first side condensing pipe (L4), the second side condensing pipe (L6), and the front condensing pipe (L8) are filled with foam insulation into the space between the inner case 120 and the outer case 110 described above, It can be inserted and fixed inside the insulation.

Meanwhile, the second side condensation pipe L6 is connected to the evaporators 630a and 630b through a fifth connection pipe L9. The evaporators 630a and 630b are disposed in the space on the rear side of the grill fan modules 500a and 500b among the respective portions in the inner case 120. That is, when the air is sucked from the lower side of the storage space 121 by the operation of the grill fan modules 500a and 500b and then discharged air to the upper side of the storage space 121, the air is converted into the evaporator 630a. ,630b) to allow heat exchange.

These evaporators (630a, 630b) are composed of plate-type evaporators (630a, 630b), so that it can be stably installed in front of the rear side of the inner wall surface of the inner case 120, while improving heat exchange performance in a narrow space. To be there. Reference numeral L10 denotes an evaporator connection pipe connecting the evaporators 630a and 630b and the main control valve 625.

Although not shown, a dryer and a capillary tube may be further installed between the front condensation pipe L8 and the evaporators 630a and 630b. In this case, the refrigerant flows in the order of the front condensing pipe L8-dryer-main control valve 625-capillary tube-evaporators 630a and 630b. Here, the dryer serves to protect the system by trapping moisture and foreign substances, and the capillary tube acts as throttling.

And, finally, the refrigerant that has passed through the evaporators 630a and 630b flows back into the refrigerant inlet pipe 610b (refer to FIG. 8) of the compressor 610 to repeat the refrigeration cycle.

Next, the control module 700 will be described with reference to FIGS. 10 to 15. The control module 700 is installed in the machine room 201. The control module 700 is for controlling various functions of the refrigerator, and may control all of various functions such as temperature control of the storage space 121, communication, and display of information through the display module 800. The control module 700 may be installed inside the machine room 201 to save the internal space of the cabinet 100.

Prior to the description of the control module 700, looking at the structure in which the control module 700 is installed, the control module 700 is installed on the bottom of the cover plate 250 in this embodiment. An installation rail 260 is provided on the bottom of the cover plate 250, and the installation rail 260 is provided in a direction parallel to the direction in which the discharge port 225b is opened, and the control module 700 is installed. Along the rail 260, it is possible to enter and exit the outlet 225b. 10 shows a state in which the control module 700 is completely separated to the outside of the machine room 201. In contrast, the installation rail 260 may be installed parallel to the direction in which the intake port 225a is opened, but it is installed on the outlet port 225b so as not to interfere with the flow of air sucked into the inlet port 225a. It is more preferable.

Referring to FIG. 11, the installation rails 260 are configured as a pair spaced apart from each other so as to be coupled to both sides of the control module 700 and extend in parallel. The control module 700 may be slidably assembled between a pair of the installation rails 260. Among the pair of installation rails 260, the installation rail 260 on the left side is divided into a first rail 260a, and the installation rail 260 on the right side is divided into a second rail 260b.

At this time, the first rail (260a) is installed on the bottom surface of the cover plate 250 covering the upper portion of the machine room frame (200), and the second rail (260b) is the first rail (260b) on the bottom surface of the cover plate (250). It is installed in a direction parallel to the rail 260a. That is, although the first rail 260a and the second rail 260b are independently represented in FIGS. 11 and 12, the first rail 260a and the second rail 260b are actually It is installed on the bottom. However, the cover plate 250 is omitted in the drawing so that the first rail 260a and the second rail 260b can be clearly seen.

Looking at the structure of the first rail 260a, the first rail 260a includes a first fixing frame 262 and a first guide frame 264. The first fixing frame 262 is a portion that is fixed to the bottom of the cover plate 250 and allows the first rail 260a to be firmly fixed to the cover plate 250. In addition, a first guide channel H1 into which a part of the side surface of the control module 700 is fitted is formed in the first guide frame 264. The first fixing frame 262 and the first guide frame 264 are orthogonally connected to each other in an approximately'L' shape. Of course, the first guide frame 264 may also be fixed to the bottom surface of the cover plate 250 by fasteners or the like.

11, a first guide channel H1 is formed in the first guide frame 264. Since the first guide channel H1 is open to the front, one side edge of the storage case 710 constituting the control module 700 may be fitted. In the first guide frame 264, the upper surface portion 264a, the side portion 264b, and the lower fixing portion 264c are connected to each other in a'U' shape, and a first guide channel H1 is formed therebetween. .

Meanwhile, looking at the structure of the second rail 260b, the second rail 260b includes a second fixing frame 265 and a second guide frame 267, similar to the first rail 260a. The second fixing frame 265 is a portion that is fixed to the bottom of the cover plate 250 and allows the second rail 260b to be firmly fixed to the cover plate 250. In addition, a second guide channel H2 into which a part of the side surface of the control module 700 is fitted is formed in the second guide frame 267. The second fixing frame 265 and the second guide frame 267 are orthogonally connected to each other in an approximately'L' shape. Of course, the second guide frame 267 may also be fixed to the bottom surface of the cover plate 250 by fasteners or the like.

11, a second guide channel H2 is formed in the second guide frame 267. The second guide channel H2 is formed to face the first guide channel H1 and is open to the front so that one side edge of the storage case 710 constituting the control module 700 is fitted. I can. In the second guide frame 267, the upper surface portion 267a, the side portion 267b, and the lower fixing portion 267c are connected to each other in a'U' shape, and a first guide channel H1 is formed therebetween. .

As described above, in this embodiment, the installation rail 260 is configured to be separated into two rails, and thus can be assembled independently of each other. Therefore, errors generated in the manufacturing process of the installation rail 260 can be compensated to some extent during the installation process.

The first fixing frame 262 and the second fixing frame 265 are at complementary positions, so that the first rail 260a and the second rail 260b form a square shape as a whole. Of course, unlike this, the first rail 260a and the second rail 260b are connected to each other, so that the installation rail 260 may be configured as a single component. Alternatively, at least one of the first rail 260a or the second rail 260b of the installation rail 260 may be integrally formed on the bottom surface of the cover plate 250.

Looking at the control module 700, both side surfaces of the control module 700 are slidably assembled to the first rail 260a and the second rail 260b, respectively. And, as shown in FIG. 10, when the suction/discharge grill 220 of the machine room frame 200 is separated from the front of the machine room frame 200, the front of the control module 700 is Can be exposed. In FIG. 2, S denotes a part in which the control module 700 is installed.

As described above, in this embodiment, the control module 700 is installed in the machine room 201 and is disposed adjacent to the front surface of the machine room 201 so as to face the suction port 225a or the discharge port 225b. More precisely, the control module 700 is installed above the machine room 201 adjacent to the outlet 225b, and when the control module 700 is installed in the machine room 201, the control module 700 The outlet 225b is formed between the bottom surface of the machine room frame 200 and the bottom surface of the machine room frame 200. Accordingly, the control module 700 may be installed at a position close to the entrance of the machine room 201 and separated to the front of the machine room 201.

In particular, it is not necessary to open the rear of the refrigerator for maintenance of the control module 700, and the control module 700 can be separated from the front of the refrigerator to repair or replace, and the machine room assembly of the present invention is built-in refrigerator. If applied to, it is possible to perform work in front of the refrigerator without having to remove the entire refrigerator from the installation site.

The control module 700 is installed in parallel with the upper surface of the machine room frame 200 while facing the upper surface of the machine room frame 200 corresponding to the ceiling of the machine room 201, that is, the bottom surface of the cover plate 250. In other words, as shown in FIG. 15, the control module 700 is installed inside the machine room 201 in a lying state. Therefore, since the main control board 780 constituting the control module 700 is stored in a state lying parallel to the inside of the storage case 710, which is a kind of drawer structure, the main control board 780 is fixed with a separate fastener. It can be stably stored even if it is not. Of course, it is also possible to fix the main control board 780 to the storage case 710 using a separate fastener such as a bolt.

As described above, since the control module 700 is installed on the cover plate 250 covering the upper portion of the machine room 201, vibrations generated from devices such as the compressor 610 installed on the bottom surface of the machine room 201 are prevented from occurring in the control module ( 700) can be prevented from being transmitted directly. In order to reinforce this function, a separate damper (not shown) may be installed between the installation rail 260 and the control module 700 or between the installation rail 260 and the cover plate 250.

In addition, since the control module 700 is accommodated in a state lying in parallel in the width direction rather than in the height direction of the machine room 201, it is possible to secure a left and right installation space corresponding to at least the width direction of the outlet 225b. Therefore, the area of the main control board 780 constituting the control module 700 can be sufficiently increased. In fact, referring to FIG. 8, it can be seen that the control module 700 occupies most of the area from the outlet 225b side except for the portion in which the compressor 610 is installed.

Looking at the specific structure of the control module 700, the control module 700 includes a storage case 710 and a main control board 780. The storage case 710 is detachably assembled to the upper portion of the machine room 201, that is, the installation rail 260, and has a storage space 701 in the center. 13 and 14, the storage case 710 has a substantially rectangular frame structure, and is opened upward to expose the storage space 701.

The storage case 710 has a width less than or equal to the width of the discharge port 225b so as to be able to enter and exit the discharge port 225b. In addition, it is preferable that the storage case 710 is less than 1/2 of the height of the discharge port 225b in a separated state so as not to reduce the height of the discharge port 225b excessively.

14, the storage case 710 is provided with protective walls 712, 713, and 714. The protective walls 712, 713, and 714 protrude along the edge of the storage case 710 so as to surround the storage space 701, and the height of the protective walls 712, 713, and 714 becomes the height of the storage case 710.

The protective walls 712,713,714 include a rear wall 712 facing the inside of the machine room 201 and a front wall 713 facing the outside, and a guide end 715 along the side wall 714 constituting the side surface There is this. The guide end 715 is a part that is assembled to the installation rail 260, and the guide end 715 extends long along the side wall 714 of the storage case 710 so that the first of the installation rail 260 It is fitted into the guide channel H1 and the second guide channel H2.

Of course, the structure in which the storage case 710 is assembled inside the machine room 201 is not necessarily limited to this structure. For example, the storage case 710 is not assembled in the machine room 201 with a sliding structure in front and rear with respect to the front of the machine room 201, but after inserting the storage case 710 into the machine room 201, A locking structure that is pushed and fixed in a direction orthogonal to the inserted direction may be applied to the machine room 201.

The guide end 715 is provided at an upper end closest to the bottom surface of the cover plate 250 covering the machine room 201 from the side wall 714 of the storage case 710. That is, the guide end 715 is provided along the upper end of the side wall 714 and protrudes outward from the upper end of the side wall 714. As the guide end 715 is provided on the upper end of the sidewall 714, the storage case 710 may be installed to be in close contact with the bottom of the cover plate 250. In this case, even without a separate cover, the upper surface of the storage space 701 can be shielded by the cover plate 250, and foreign matters can be prevented from entering the storage space 701.

Partition walls 720 are located inside the protective walls 712, 713, and 714 of the storage case 710. The storage case 710 of the control module 700 has a storage space 701 in which the main control board 780 is accommodated, and the partition wall 720 divides the storage space 701 again. . More precisely, the partition wall 720 surrounds the storage space 701 to form a wire connection space 702 outside the storage space 701. That is, a wire connection space 702 is formed between the partition wall 720 and the protective walls 712, 713, and 714.

A wire harness connected to the main control board 780 is mounted in the wire connection space 702. Since the wire connection space 702 is an independent space from the storage space 701, the wire harness can be easily arranged. In particular, there is a high possibility that a plurality of wire harnesses in the narrow machine room 201 are twisted or interfere with surrounding parts including the part P of the main control board 780, through the wire connection space 702. You can organize them. In this embodiment, the wire connection space 702 has an approximately'a'-shaped path. Unlike this, the wire connection space 702 may be formed to cover all the outer sides of the storage space 701.

As such, the partition wall 720 functions as a kind of double wall together with the protective walls 712, 713, and 714. Accordingly, the partition wall 720 may filter once more foreign matters flow into the main control board 780.

At this time, at least one through hole 722, 723, and 724 is opened in the partition wall 720, and the storage space 701 and the wire connection space 702 are connected to each other through the through holes 722, 723, and 724. A wire harness is branched through a connector or the like to the main control board 780 installed in the storage space 701, and the wire harness can be passed to the wire connection space 702 through the through grooves 722, 723, and 724. In this embodiment, a plurality of through holes 722, 723 and 724 are formed along the partition wall 720.

15, a hook portion 730 protrudes from the bottom or side surface of the wire connection space 702. The hook portion 730 is for fastening and fixing a wire harness disposed in the wire connection space 702, and a plurality of hook portions 730 may be provided along the wire connection space 702. The hook portion 730 has a hook structure that prevents the wire harness from being separated again by being elastically deformed and restored in the process of fastening the wire harness. Of course, unlike this, the hook portion 730 may simply have a protruding structure or may be a hole into which a part of the wire harness is inserted.

In the storage case 710 of the control module 700, a connection hole 712' is passed through the rear of the machine room 201 toward the inside. The connection hole 712 ′ allows a part of the wire harness connected to the control module 700 to extend to the outside of the storage case 710 through it. In this embodiment, the connection hole 712 ′ Is formed through the rear of the wire connection space 702.

Next, the operation of the refrigerator according to the embodiment of the present invention will be described in more detail.

First, when the door assembly 130 is closed while food is stored in the storage space 121, the storage space 121 becomes a closed space. In this state, when the operation of the air conditioning module 600 starts, the temperature control function of the refrigerator starts. That is, while the heat dissipation fan 611, the compressor 610, the main condenser 620, and the evaporator 630 constituting the air conditioning module 600 are operated, the air conditioning operation is performed.

In particular, when such an air-conditioning operation is performed, indoor air is sucked into the machine room 201 through the inlet 225a of the intake/discharge grill 220 installed in the open front of the machine room 201 and the intake/discharge grill 220 The air passing through the machine room 201 is discharged through the discharge port 225b of ). At this time, the indoor air sucked through the inlet 221 passes through the main condenser 620, the heat dissipation fan 611, and the compressor 610 in sequence, heat exchange and heat dissipation, and then is discharged into the room through the outlet 222.

In this case, water is generated inside the machine room 121 during the operation of the air conditioning module 600, and the defrost water generated in the evaporator 630 falls and is collected in the defrost water tray 240. Defrost water accumulated in the defrost water tray 240 may be naturally evaporated by the evaporation pipe L2 disposed in the defrost water tray 240.
