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 compressor and a condenser are 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.

However, in the case of such a built-in refrigerator, the rest of the refrigerator except the front side of the refrigerator is often blocked, making it difficult for the air to flow smoothly. Accordingly, various technologies have been developed to smooth the flow of air for cooling the condenser and the compressor installed in the machine room of the refrigerator. Among them, there are technologies in which both the inlet through which air flows into the machine room and the outlet through which air inside the machine room is discharged are arranged in the front of the refrigerator.

For example, Japanese Patent Publication No. 2017-141975 (prior art 1), Korean Patent Publication 2011-0019076 (prior art 2), U.S. Patent No. 5,881,567 (prior art 3), Japanese Patent 5033563 (prior art 4), etc. There is this.

However, in the prior art 1, since the cooling fan is in close contact with one side of the condenser, the size of the cooling fan is limited to the height around the condenser, and air may not be concentrated to the compressor by partially overlapping the compressor and the condenser in the width direction. Also, in the case of prior art 2, there is a problem that the overall height of the machine room is increased because the condenser and cooling fan are installed in the upright direction, and in the prior art 3, the cooling fan is far from the suction port by placing a cooling fan at the rear of the condenser and compressor. It is difficult to inhale air smoothly. In the case of prior art 4, the height of the machine room is high because the condenser is installed in the erect direction, and efficient air flow is difficult because the air path to the compressor is not clearly distinguished.

In other words, these prior art 1 to prior art 4 have limitations in miniaturizing the machine room due to the installation direction or overall height of the condenser and cooling fan, or the air flow inside the machine room is not clearly distinguished, so that the flow of air by the cooling fan is difficult. There is a problem that is not efficient.

Of course, if the size of the condenser or the heat dissipation fan is reduced, the volume of the machine room can be reduced. However, in this case, the heat dissipation performance is deteriorated, and as a result, the efficiency of the refrigeration cycle is deteriorated.

In particular, a built-in type refrigerator can be used in the recently widely applied Island Kitchen (Kitchen Island). The island type kitchen furniture, which is a workbench independent from the sink, has high convenience, but the overall height is low, so the refrigerator is applied as a built-in type. More difficult to do.

Japanese Patent Publication 2017-141975 Republic of Korea Patent Publication 2011-0019076 US registered patent US5,881,567 Japanese registered patent 5033563

The present invention is to solve the problems of the prior art as described above, and an object of the present invention is to reduce the total volume of the machine room by efficiently arranging a condenser, a compressor, and a radiating fan inside the machine room of a refrigerator, while reducing the heat dissipation of the condenser and the compressor. Performance is what makes it possible to secure it.

Another object of the present invention is to secure a relatively larger storage space of a refrigerator by reducing the overall volume of the machine room without reducing the size (diameter) of the heat dissipation fan.

Another object of the present invention is to make the intake port through which air flows into the machine room relatively wide so that the inlet of outside air is smooth, but the introduced air is concentrated in the direction of the circulation fan.

Another object of the present invention is to increase heat dissipation performance by dispersing the condenser at various locations inside the refrigerator.

Another object of the present invention is to reduce the overall size of a refrigerator by installing a control module and a door opening device in the machine room.

According to a feature of the present invention for achieving the above object, the present invention is provided with a condenser, a compressor, and a heat dissipating fan inside the machine room. The condenser is installed in the machine room so as to face the suction port adjacent to the suction port, and the compressor is disposed in a space partitioned from the space where the condenser is installed in the machine room, and is spaced from the front of the machine room to the inside of the machine room. Is installed in front of the rear plate of the machine room frame.

The heat dissipation fan is installed between the compressor and the condenser on the air flow path inside the machine room, and is spaced apart from the front of the machine room to the inside of the machine room and installed in front of the rear plate. In this way, the compressor and heat dissipation fan are installed inside the machine room far from the intake/exhaust port, so parts that are higher in height than other parts are concentrated in the rear of the machine room and the rest of the parts are installed in the front, so that the front of the machine room is lowered. I can.

In addition, the compressor and the heat dissipation fan are disposed so that at least a portion of the compressor and the heat dissipation fan overlap each other along a direction orthogonal to a direction in which the suction port and the discharge port are opened. In this case, the rear space of the machine room for matching the height of the compressor and the heat dissipation fan can be relatively small, and the remaining space can be used widely.

In addition, since the compressor is disposed on a path in which the discharge port is opened, hot air passing through the compressor can be discharged directly without interference with surroundings.

In addition, the heat dissipation fan and the compressor are installed to face each other in front of a rear plate of the machine room frame, and an extension direction of a rotation axis of the heat dissipation fan faces the compressor. In this case, since the heat dissipation fan and the compressor are arranged side by side with each other, the part to be made high in the machine room can be minimized, and the front side can be widely used as a storage space.

And the heat dissipation fan is spaced apart from the side plate of the machine room frame extending along one side of the inlet to create an air flow space connected to the inlet between the side plate, and the extending direction of the rotation axis of the heat dissipation fan is the It is orthogonal to the direction in which the suction port is opened. In this case, the distance between the heat dissipation fan and one side wall of the machine room is increased, and air can be sucked into the heat dissipation fan while smoothly passing therebetween.

In addition, in the machine room, a separation partition wall having one end disposed between the inlet and the outlet is installed to partition the inside of the machine room into both sides, and the opposite end of the separation partition is connected to the heat dissipation fan. Therefore, the inside of the machine room is divided by a separation partition, so that the suction path through which outside air is introduced and the discharge path through which the air passing through the machine room is discharged can be distinguished from each other, and the air along a certain path inside the machine room, that is, condenser-cooling fan-compressor. Since the flow of the air can be made smoothly.

In addition, the heat dissipation fan is installed to block a space spaced between the separation partition wall and the rear plate. As described above, in the present invention, the heat dissipation fan is installed so as to be connected to the separation partition wall, so that the heat dissipation fan itself becomes a kind of separation partition wall. Therefore, since air can flow toward the compressor only through the heat dissipation fan, it is possible to prevent the high temperature heat generated from the compressor from affecting the condenser.

In addition, the suction port is wider than the discharge port, and the inner space of the machine room connected from the suction port is formed to be narrowed by a separation partition wall installed to partition the machine room when the condenser is installed. By securing the area of the inlet as wide as possible, cooling of the condenser adjacent to the inlet port can be performed more smoothly, and the heat dissipation function of the condenser can be implemented as effectively as possible without interfering with the installation of the compressor and heat dissipation fan past the area where the condenser is installed. I can.

In addition, the inner space of the machine room formed between the inlet and the heat dissipation fan is blocked by a lower plate, a side plate, and a rear plate of the machine room frame, and the inner space of the machine room formed between the heat dissipation fan and the discharge port is At least a portion of the lower plate, the side plate, or the rear plate is opened to communicate with the outside. Therefore, the initial inflow of outside air is limited to a specific direction (condenser), but once the condenser and compressor are radiated, they can be discharged in various directions, thereby improving the heat dissipation performance of the machine room.

The compressor and the condenser are connected to each other by an evaporation pipe, and the evaporation pipe is arranged while being bent several times along the bottom of the defrost water tray installed in the machine room. Therefore, evaporation of the defrost water can be rapidly performed.

The defrost water tray includes a tray body in which a defrost water space is formed inside by a partition fence provided along the edge, and a condenser seat plate protruding from one side of the tray body in the direction of the suction port and on which the condenser is installed. Includes.

In addition, the defrosting water tray has a condenser seating plate, and a condenser fixing part protrudes from the condenser seating plate to fix a portion of the side of the condenser. Therefore, the condenser can be firmly fixed using the defrost water tray without the need to fix the condenser on a separate plate.

And the partition fence of the defrost water tray protrudes to a position higher than the lower end of the heat dissipation fan, and at least a part of the partition fence of the defrost water tray extends downwardly inclined toward the lower end of the heat dissipation fan, so that the heat dissipation fan and the partition fence A flow space is formed between them. Accordingly, a flow space can be secured between the lower end of the heat dissipation fan and the defrost water tray, and air can be well sucked by the heat dissipating fan from the lower end of the heat dissipating fan.

In addition, a side condensing pipe is connected to the condenser, and the side condensing pipe is disposed in a vertical direction along at least one of both side surfaces of the machine room frame. Since the side condensation pipe assists the main condenser and condenses the refrigerant together, the size of the main condenser can be made relatively small.

In the machine room, a control module is installed in a space between the compressor and the outlet, the control module is spaced apart from the bottom of the machine room to the top of the machine room, and between the bottom of the control module and the bottom of the machine room. A flow path is formed. As described above, in the machine room, not only devices for implementing the refrigerant cycle but also a control module may be installed to increase space utilization. At this time, the control module may be installed at a position close to the entrance of the machine room and separated to the front of the machine room.

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

Even though the refrigerator of the present invention has a closed structure, air is sucked and discharged from the front of the machine room, so even if it is installed in a narrow and narrow space such as the built-in method, air circulation can be smoothly performed, so that the cooling performance and the efficiency of the refrigerator are improved. Improves.

And, in the present invention, the compressor and the heat dissipation fan are installed inside the machine room far from the suction/discharge port. That is, the height of the machine room can be lowered in front of the machine room, and the storage space of the refrigerator can be increased by lowering the height by concentrating parts having a higher height than other parts in the rear of the machine room and installing the remaining parts in the front. Therefore, there is an effect of improving the space utilization rate of the refrigerator.

In addition, in the present invention, the compressor and the condenser are respectively disposed in a partitioned space, and a heat dissipating fan is installed therebetween. Therefore, it is possible to reduce the high-temperature heat generated from the compressor from affecting the condenser, and the heat dissipation of the condenser can be made more effectively.

In particular, in the present invention, since the heat dissipation fan installed between the compressor and the condenser can itself serve as a partition wall, it can more effectively prevent the heat of the compressor from being transmitted to the condenser, so that the cooling efficiency of the condenser and the energy efficiency of the refrigerator Can increase.

Further, in the present invention, the compressor and the heat dissipation fan having a high height are arranged in a direction orthogonal to the direction in which the suction port and the discharge port are opened, that is, at least partially overlap each other along the left and right direction from the rear of the machine room. Therefore, it is possible to install a heat dissipation fan as large as the height of the compressor, and through this, heat dissipation inside the machine room may be made more effectively.

In particular, in the present invention, since the heat dissipation fan faces the compressor so that the extension direction of the rotation shaft faces the compressor, a heat dissipation fan having a sufficiently large diameter corresponding to the size of the compressor can be installed in the machine room. There is also an effect of improving the heat dissipation performance.

In addition, in the present invention, the inlet of the machine room is wider than the outlet. By securing the area of the inlet as wide as possible, cooling of the condenser adjacent to the inlet port can be performed more smoothly, and the outlet side is formed to be relatively wider after passing the area where the condenser is installed. Therefore, it is possible to implement the heat dissipation function of the condenser as effectively as possible without disturbing the installation of the compressor and the heat dissipation fan.

In particular, the condenser is installed close to the suction port for cooling the condenser, which is more important in increasing the efficiency of the refrigeration cycle, and the left and right widths of the suction port are formed larger than the left and right widths of the condenser, so that the condenser can be radiated by meeting a sufficient amount of outside air.

On the other hand, in the present invention, the inside of the machine room is partitioned by a separation partition, and a suction path through which outside air is introduced and a discharge path through which air passing through the inside of the machine room is discharged may be distinguished from each other. Accordingly, in the present invention, since air flows along a certain path inside the machine room, that is, a condenser-cooling fan-compressor, air circulation can be smoothly performed.

In addition, in the present invention, the heat dissipation fan is installed so as to be connected to the separation partition wall, so that the heat dissipation fan itself becomes a kind of the separation partition wall. Therefore, air can flow toward the compressor only through the heat dissipation fan. In particular, since air flows in the direction of the compressor by the radiating fan, it is possible to more reliably prevent the high temperature heat generated from the compressor from affecting the condenser.

In addition, in the present invention, the internal space of the machine room formed between the inlet and the heat dissipation fan is blocked, so the inflowed outside air is concentrated only in the direction of the heat dissipation fan through the condenser, but the inner space of the machine room formed between the heat dissipation fan and the discharge port is the floor, The side or back is opened to communicate with the outside. Therefore, the initial inflow of outside air is limited to a specific direction (condenser), but once the condenser and compressor are radiated, they can be discharged in various directions, thereby further enhancing the heat dissipation performance of the machine room.

In addition, in the present invention, the condenser includes a side condensing pipe built along the side of the cabinet together with the main condenser installed inside the machine room. Since the side condensing pipe assists the main condenser and condenses the refrigerant together, the size of the main condenser can be made relatively small, and the size of the machine room assembly can be reduced.

In addition, the side condensation pipe is built inside the side of the cabinet to increase the side temperature of the refrigerator, thereby preventing dew from forming on the outer surface of the refrigerator due to a temperature difference between the inside and the outside of the refrigerator.

In addition, in the present invention, a defrost water tray is installed on the bottom of the machine room assembly to store defrost water, and the storage capacity of the defrost water tray can be increased by extending the defrost water tray to a position close to the heat dissipation fan.

At the same time, the defrost water tray adjacent to the lower end of the heat dissipation fan has an inclined surface (flow guide surface) inclined downward toward the heat dissipation fan, eliminating dead space between the lower end of the heat dissipating fan and the defrost water tray, and securing sufficient flow space. have. Therefore, even at the lower end of the heat dissipating fan, air can be smoothly sucked by the heat dissipating fan.

In addition, in the present invention, a condenser is installed in the defrost water tray, and a condenser fixing part protrudes from the defrost water tray, so that a part of the side of the condenser is hung and fixed. Therefore, the condenser can be fixed to a separate plate, and the condenser can be firmly fixed using the defrost water tray without the need to install it again inside the machine room assembly, so the installation stability of the condenser can be increased and the number of parts can be reduced.

In addition, a control module as well as devices for implementing the refrigerant cycle may be installed in the machine room to increase space utilization. At this time, 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.

Referring to FIG. 1, the cabinet 100 forms the exterior of a refrigerator, and the overall height is made low as shown. The refrigerator of this embodiment is a built-in type refrigerator installed inside an island dining table, and has a lower height than a general refrigerator. Therefore, not only the internal capacity but also the space in which each component can be installed is small. Therefore, in order to utilize a small and low installation space, it is necessary to effectively arrange the parts. To this end, in this embodiment, parts including the compressor 610 are effectively disposed, and the control module 700 is installed inside the machine room assembly. This structure will be described below.

In FIG. 4, the components constituting the cabinet 100 are shown in an exploded state. As can be seen, the outer case 110 has a substantially hexahedral shape open to the front and rear and downwards, and the inner case 120 is installed in the outer case 110 to be spaced apart from the outer case 110. In addition, the back plate 115 is assembled on the rear of the outer case 110, the front frame 118 is assembled on the front, and the cover plate 250 is assembled on the bottom.

In a state in which the inner case 120 is located inside the outer case 110, the back plate 115, the front frame 118, and the cover plate 250 are assembled to the outer case 110, respectively, and the inner case 120 is Foam insulation (not shown) is filled into the space between the case 120 and the outer case 110. At this time, a filling hole 116 is passed through the back plate 115, and a foam insulation material may be injected through the filling hole 116.

In this way, when the foam insulation is filled between the outer case 110 and the inner case 120, some of the wire harness (not shown) and side condensation pipes (L4, L6, see FIG. 6) to be described below, and The front condensing pipe L8 may be embedded in the foam layer. Therefore, a part of the wire harness and the side condenser can be naturally fixed during the filling process of the foamed insulating material.

There is a storage space 121 inside the inner cabinet 100. The storage space 121 is a space for storing food, and the storage space 121 may be divided into a plurality of compartments by beds 330a to 300d. A guide rail 122 is provided on the inner wall of the storage space 121, and the beds 330a to 300d are moved back and forth under the guidance of the guide rail 122, and can be removed from the storage space 121 in a drawer type. It is structured to be.

There is an avoidance part 123 on the bottom surface of the storage space 121. The avoiding part 123 is a part protruding upward from the bottom surface of the storage space 121, and the avoiding part 123 is for avoiding interference with the compressor 610 of the machine room assembly to be described below. Due to the avoidance part 123, a part of the bottom side of the storage space 121 has a stepped space.

A door assembly 130 is provided on the front of the cabinet 100. The door assembly 130 is for opening and closing the storage space 121 of the cabinet 100, and in this embodiment, the door assembly 130 has a structure that opens and closes through rotation. More precisely, the door assembly 130 is in close contact with the front frame 118 of the cabinet 100 to shield the storage space 121 or rotate away from the front frame 118 to open the storage space 121 Let it.

That is, the refrigerator according to the embodiment of the present invention forms a sealed storage space 121 by the door assembly 130 described above. In particular, the sealed storage space 121 can store food while maintaining a constant temperature without loss of cold air by the grill fan modules 500a and 500b and the air conditioning module 600. In this embodiment, at least a part of the door assembly 130 is made of a transparent viewing window 142 structure, so that the storage space 121 can be viewed from the outside.

In this case, the viewing window 142 is preferably formed of a material capable of internal viewing, and may be formed of, for example, glass. When the viewing window 142 is formed of glass, a protective film (not shown) may be attached to the glass. At this time, the protective film is preferably made of a film for blocking light (partially blocking) that minimizes reflection by transmitting light in the storage space 121 indoors. Of course, instead of the protective film, the viewing window 142 itself may be formed to have a dark color, so that the indoor transmission of light may be minimized.

Next, referring to the machine room frame 200 constituting the machine room assembly, the machine room frame 200 is provided to form the lower structure of the refrigerator according to the embodiment of the present invention. An air conditioning module 600 to be described below is installed in the machine room frame 200, and the cabinet 100 described above is coupled to an upper portion of the machine room frame 200.

The machine room frame 200 is installed under the outer case 110 as shown in FIG. 1 and has a substantially rectangular frame shape as shown in FIG. 3. In this embodiment, the machine room frame 200 has an open upper part, and there is a machine room 201 therein, so that at least a part of the air conditioning module 600 may be installed.

Referring to FIG. 7, the machine room frame 200 includes a lower plate 211 forming a floor, side plates 212 forming both side walls, and a rear plate 213 forming a rear surface. In addition, a cover plate 250 (refer to FIG. 3) is coupled to an upper portion of the machine room frame 200 to shield the machine room 201 inside. In this embodiment, the cover plate 250 may be assembled under the cabinet 100 and viewed as a part of the cabinet 100, but it may also be viewed as a part of the machine room frame 200 because it also constitutes the upper part of the machine room frame 200. have.

The machine room frame 200 is provided with heat dissipation holes 211 ′ and 214. The heat dissipation holes 211 ′ and 214 are parts that connect the machine room frame 200 to the outside in addition to the suction/discharge grill 220 on the front side to be described below. As shown in FIG. 7, a radiating hole 214 may be formed in the rear plate 213, and a radiating hole 211 ′ may be formed in the lower plate 211 as shown in FIG. 11, which is a bottom view. In addition, although not shown, a heat dissipation hole may be formed in the side plate 212 as well.

At this time, there is no heat radiating hole in the inner space (suction space I) of the machine room 201 formed between the suction port 225a and the heat radiating fan 611 to be described below. That is, the suction space I formed between the suction port 225a and the heat dissipation fan 611 is blocked by the lower plate 211, the side plate 212, and the rear plate 213 of the machine room frame 200. There is.

In contrast, the inner space (discharge space O) of the machine room 201 formed between the heat dissipation fan 611 and the discharge port 225b is the lower plate 211, the side plate 212, or the rear plate 213 ) At least some of them are opened through the heat dissipation holes 211 ′ and 214 to communicate with the outside. Referring to FIG. 11, a heat dissipation hole is formed in the lower plate 211, there is no heat dissipation hole around the suction space I at the front entrance of the machine room frame 200, and the heat dissipation hole 211 ′ in the discharge space O, 214) can be seen to exist.

According to this structure, the suction space I, which is the internal space of the machine room 201 formed between the suction port 225a and the heat dissipation fan 611, is blocked, so that the incoming outdoor air passes through the main condenser 620 and the heat dissipation fan 611 Although it is concentrated only in the direction, the discharge space (O) of the machine room 201 formed between the heat dissipation fan 611 and the discharge port 225b is partially opened through the heat dissipation holes 211 ′ and 214 Is connected to the outside. Therefore, the initial inflow of outside air is limited to a specific direction, that is, toward the main condenser 620, but once the main condenser 620 and the compressor 610 are radiated, they can be discharged in various directions, thereby increasing the heat dissipation performance of the machine room. .

7 and 8, in this embodiment, the suction port 225a is wider than the discharge port 225b. However, when the suction space I of the machine room 201 connected from the suction port 225a passes the area where the main condenser 620 is installed, the width is narrowed by the separation partition wall 230 installed to partition the machine room 201. It is formed to lose.

That is, by widening the intake port 225a, the amount of air initially introduced is increased, and through this, the main condenser 620 can be effectively cooled. In addition, after passing the area for cooling the main condenser 620, the suction space (I) is reduced, and the remaining space can be used as a space for installing the compressor 610, the blowing fan 611, the control module 700, etc. .

Referring to FIG. 10, the rear plate 213 has a protective plate 213 ′, which partially protrudes upward, and the protective plate 213 ′ is formed higher than the compressor 610 and thus provides the compressor 610. It serves to protect.

On the other hand, the machine room frame 200 and the inner case 120 are disposed to be spaced apart from each other, and the side plates 212 and the rear plate 213 of the machine room frame 200 have both side and rear surfaces of the outer case 110. It can be configured to be connected to.

Inside the machine room frame 200, there is a machine room 201 (refer to FIG. 7). The machine room 201 is an empty space, which is a kind of installation space, in which a part of the apparatus constituting the air conditioning module 600 is installed. The machine room 201 is a separate space independent from the storage space 121 described above, and provides a space in which the air conditioning module 600 can be installed and operated.

Although not shown, the inner case 120 and the machine room frame 200 may be composed of one component. In this case, by providing a separate partition wall between the storage space 121 and the machine room 201 The storage space 121 and the machine room 201 may be separated from each other.

A suction and discharge grill 220 is provided on the opened front of the machine room frame 200 in front of the machine room 201. The suction/discharge grill 220 guides the flow of air sucked into the machine room 201 from the outside of the machine room 201 or air discharged from the machine room 201 to the outside of the machine room 201 while guiding the flow of the machine room 201. It plays the role of blocking the open front of the building.

In addition, the suction and discharge grill 220 is provided with a suction port 225a and a discharge port 225b. At this time, the suction port (225a) and the discharge port (225b) is made to be provided separately at a position separated from each other by a separation partition wall 230 to be described later, in an embodiment of the present invention, the suction port (225a) and the left side when viewed from the front It is divided into the discharge port 225b on the right, but it may be vice versa. For reference, referring to FIG. 6 in which the suction and discharge grill 220 is separated from the machine room frame 200, the inlet of the suction space I and the outlet of the discharge space O are exposed at the front entrance of the machine room frame 200. Has been.

8, a main condenser 620 and a defrost water tray 240 are installed in the suction space I of the machine room frame 200, and a compressor 610 and a control module 700 are installed in the discharge space O. Is installed. And between the suction space (I) and the discharge space (O) in the middle there is a heat dissipation fan (611). The heat dissipation fan 611 serves as a sort of partition wall, and more precisely, divides the inner space of the machine room 201 together with the separation partition wall 230.

Looking at the separation partition wall 230, a separation partition wall 230 that divides the machine room 201 into two spaces is provided in the machine room frame 200. That is, a flow path through which air is sucked into the machine room 201 and a flow path through which air is discharged may be divided by the separation partition wall 230. A flow path through which air is sucked into the machine room 201 starts from the suction port 225a of the suction/discharge grill 220, and a flow path through which air is discharged from the machine room 201 is an outlet of the suction/discharge grill 220 It ends at (225b).

In addition, the left and right spaces in the machine room 201 separated by the separation partition wall 230 are connected to each other at a position near the rear of the machine room 201, that is, the rear plate 213. That is, the rear end portion of the separation partition wall 230 is formed so as not to reach the rear plate 213 so as to be spaced apart so that a portion connected to each other is generated. Of course, although not shown, the rear end side of the separating partition wall 230 contacts the rear plate 213, but by forming an opening hole (not shown), both sides of the machine room 201 may be configured to communicate with each other.

In addition, a heat dissipation fan 611 is installed at a portion that is spaced apart so that the rear end portion of the separation partition wall 230 does not reach the rear plate 213 and is connected to each other, so that the heat dissipation fan 611 is a kind of wall partition wall 230 ) Becomes part of. Of course, since the heat dissipation fan 611 is open, the suction space (I) and the discharge space (O) are connected to each other based on the heat dissipation fan 611, but when the heat dissipation fan 611 is operated, the air flows into the suction space (I). Since it flows from the to the discharge space (O), it is difficult for air to flow in the opposite direction. Accordingly, it is possible to effectively prevent the heat of the compressor 610 from being transmitted to the main condenser 620, thereby increasing the cooling efficiency of the main condenser 620 and the operating efficiency of the refrigerator.

The separation partition wall 230 may be formed in a straight line, but may be formed in an inclined or bent structure. In an embodiment of the present invention, the separation partition wall 230 is formed in a bent structure. That is, by bending a part of the separation partition wall 230, it is possible to secure as much space as possible in which the main condenser 620, which will be described later, is installed.

The separation partition wall 230 includes a first partition wall 231 extending into the machine room 201 between the suction port 225a and the discharge port 225b, and extending in an inclined direction from the first partition wall 231. It may be divided into a second partition wall 232. 6 to 8, the first partition wall 231 is covered by the control module 700, but the second partition wall 232 is shown. In FIG. 9, the first partition wall 231 is shown. As shown in FIG. 9, the main condenser 620 is disposed in a space separated by the first partition wall 231.

Referring to FIG. 11, which is a bottom view of the machine room frame 200, a first partition wall 231, a second partition wall 232 extending in an inclined direction from the first partition wall 231, and the first partition wall 232 You can see the installation location of the heat dissipation fan 611 connected at ). As can be seen, the first partition wall 231, the second partition wall 232, and the heat dissipation fan 611 are continuously connected to each other to form one partition wall. Of course, there may be a predetermined gap between the second partition wall 232 and the heat dissipation fan 611, but they are arranged very close to each other to minimize the air from escaping therebetween.

Referring to FIG. 9, the height H3 of the first partition wall 231 may be greater than or equal to the height of the main condenser 620. In addition, the second partition wall 232 is connected from one end of the first partition wall 231 to one end of the heat dissipation fan 611 to be described below. Accordingly, the second partition wall 232 may prevent the introduced air from flowing in the direction of the compressor 610 without passing through the heat dissipation fan 611. The first partition wall 231 and the second partition wall 232 may be composed of one component or may be separate.

A defrost water tray 240 is provided in the machine room 201 of the machine room frame 200. At this time, the defrost water tray 240 is located on the bottom of the machine room 201 on the side where air is introduced through the inlet 225a and serves to receive the defrost water flowing from the evaporator 630 to be described later. It serves to fix the main condenser 620 in the machine room 201.

13, a main condenser 620 is installed in front of the defrost water tray 240 toward the suction port 225a, and an evaporation pipe L2 is provided on the bottom surface 241' of the defrost water tray 240. Is installed. Since the evaporation pipe L2 is disposed close to the bottom surface 241 ′ of the defrost water tray 240, it may serve to evaporate the defrost water accumulated in the defrost water tray 240. The evaporation pipe L2 will be described again below.

In addition, a blowing fan 611 is disposed on one side of the defrost water tray 240. The blowing fan 611 is not installed inside the defrost water tray 240, but is installed adjacent to the defrost water tray 240 at the rear of the defrost water tray 240. The blowing fan 611 sucks air into the machine room 201 through the inlet 225a, and discharges the air that has passed through the condenser 620 and the compressor 610 to the front outlet, that is, the outlet 225b. . The installation structure of the defrost water tray 240 and the blowing fan 611 will be described again below.

Referring to FIG. 12, the defrosting water tray 240 has a tray body 241 in the shape of a substantially rectangular frame to form a skeleton, and is inside by a partition fence 242 provided along the edge of the tray body 241. Defrost water space (Sa, Sb) is created. The partition fence 242 is a predetermined protrusion from the bottom surface 241 ′ of the tray body 241, and the defrost water generated from the evaporator 630 and dropped in the defrost water spaces Sa and Sb accumulates. .

The width of the defrost water spaces Sa and Sb becomes narrower toward the rear, and there is an inclined fence 242 ′ on one side of the partition fence 242 to narrow the width of the defrost water spaces Sa and Sb. The inclined fence 242 ′ corresponds to the second partition wall 232 extending in an inclined direction among the separation partition walls 230 described above. The second partition wall 232 is positioned adjacent to the inclined fence 242 ′. Accordingly, the inclined fence 242 ′ may be regarded as constituting a part of the partition wall together with the second partition wall 232.

As described above, since the widths of the defrost water spaces Sa and Sb become narrow, they can be divided into a relatively wide first defrost water space Sa and a relatively narrow second defrost water space Sb. Since the heat dissipation fan 611 is installed next to the second defrost water space Sb, it can be seen that the second defrost water space Sb is relatively narrow in order to provide an installation space for the heat dissipation fan 611. However, since the first defrost water space Sa is as wide as the condenser seat plate 246 in which the main condenser 620 is seated, the defrost water spaces Sa and Sb have sufficiently large storage capacities.

Meanwhile, the partition fence 242 has a fixing clip 244. The fixing clip 244 protrudes from the partition fence 242 to the defrost water spaces Sa and Sb, and has an elastic forceps shape. The fixing clip 244 is a part to which a part of the defrost water pipe 590 (refer to FIG. 18) for transferring the defrost water generated in the evaporator 630 is caught and fixed. In this embodiment, two fixing clips 244 are provided on the side of the second defrost water space Sb, and their positions and numbers may be changed. In this embodiment, the fixing clip 244 is provided on the side of the second defrost water space Sb relatively close to the evaporator 630.

One side of the tray body 241 has a condenser seating plate 246. The condenser seating plate 246 is configured in a thin plate shape, and further extends from the tray body 241 in the direction of the suction port 225a. Unlike the tray body 241, the condenser seat plate 246 does not have a partition fence 242 and is formed at the same height as the bottom surface 241' of the tray body 241.

A flow inclined surface 245' is provided between the tray body 241 and the condenser seating plate 246 to be inclined downward toward the condenser seating plate 246. The flow inclined surface 245 ′ prevents air flowing from the suction port 225a from being blocked by the partition fence 242 and not flowing naturally. To this end, the flow inclined surface 245 ′ is formed on the partition fence 242 in front of the partition fence 242 facing the condenser seat plate 246.

A main condenser 620 is installed on the condenser seat plate 246. A condenser fixing part 247 protrudes from the condenser seating plate 246 to hang and fix a part of the side of the main condenser 620. The condenser fixing part 247 includes a fixed body protruding from the condenser seating plate 246 and a hook part 248 protruding from the fixed body in the direction of the main condenser 620. The condenser fixing part 247 is composed of a pair spaced apart from each other at a predetermined interval, and the main condenser 620 is mounted between the pair of condenser fixing parts 247.

Referring to FIG. 15, it can be seen that the main condenser 620 is disposed between the condenser fixing portions 247. In this embodiment, the distance between the pair of condenser fixing portions 247 corresponds to the width of the condenser. Therefore, the hook portion 248 is in close contact with the side of the main condenser 620, but may not deform the side of the main condenser 620 during the process of being fitted. In particular, in this embodiment, a forming part made of an elastic material is covered on the surface of the hook part 248 to prevent the surface of the main condenser 620 from being scratched.

In this way, the main condenser 620 is directly connected to the defrost water tray 240 through the condenser fixing part 247 without a separate fixture. Therefore, a component or soldering process for fixing the main condenser 620 may be omitted, and the condenser fixing part 247 firmly fixes the side of the main condenser 620. In particular, it may be difficult to install the main condenser 620 inside the cramped machine room 201.In this embodiment, the main condenser 620 can be fixed only by installing the main condenser 620 on the condenser seat plate 246. I can.

Meanwhile, the defrost water tray 240 has a flow guide surface 245. The flow guide surface 245 is formed such that at least a portion of the partition fence 242 is inclined downward toward the lower end of the heat dissipation fan 611. 12 and 13, the partition fence 242 of the defrost water tray 240 protrudes to a position higher than the lower end of the heat dissipation fan 611, and the heat dissipation fan 611 is very close to the partition fence 242. Since it is located, the lower front portion of the heat dissipation fan 611 becomes a dead space, so that the flow of air may not be smooth. However, the flow guide surface 245 secures a flow space Sc between the lower end of the heat dissipation fan 611 and the defrost water tray 240, so that air intake toward the heat dissipation fan 611 can be better. To be.

14, it can be seen that air flows along the flow guide surface 245. The flow guide surface 245 may guide air sucked through the downwardly inclined surface to naturally flow toward the heat dissipation fan 611. The end of the flow guide surface 245 extends to the lower end of the heat dissipation fan 611, and the flow guide surface 245 is formed in a section of the partition fence 242 facing the heat dissipation fan 611.

Meanwhile, referring to FIG. 3, the rear portion of the cover plate 250 forming the upper surface of the machine room frame 200 protrudes upward from other portions, so that the rear portion inside the machine room 201 is formed higher than the other portions. . That is, in consideration of the protruding height of the radiating fan 611 and the compressor 610 installed in the machine room 201, the rear portion is formed higher than the other portions. In particular, since the compressor 610 has the highest height in the present embodiment, a protrusion 255 is formed on the cover plate 250 to correspond to the height of the compressor 610.

The cover plate 250 includes an auto door installation part 253 in which a door opening device 900 is installed. The auto door installation part 253 is provided in front of the cover plate 250, that is, in front of the door assembly 130, and protrudes upward to secure a space under the cover plate 250, but is open downward. The auto door installation part 253 protrudes upward, just like the rear part of the cover plate 250 protrudes upward, but the degree of protrusion of the auto door installation part 253 in this embodiment is the cover plate ( 250) is lower than the extent of the upward protrusion.

For reference, in FIG. 2, the push rod 950 constituting the door opening device 900 is shown in a protruding state, and the push rod 950 protrudes from the door opening device 900 to form the door assembly 130. Push the contact part (B) on the inner surface.

A connector housing 257 is provided on the cover plate 250. The connector housing 257 is a part in which the wire harness extending from the control module 700 to be described below is embedded, and serves to guide the extension direction of the wire harness. 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, a grill plate 270 and a grill pan module 500 of a refrigerator according to an embodiment of the present invention will be described in detail with reference to FIGS. 16 to 18. A grill plate 270 is installed inside the storage space 121. The grill plate 270 is made of a rectangular wall, and is a portion in which the grill fan module 500 is installed.

Main grill fixing ends 271 are formed on the left and right sides of the center of the rear of the grill plate 270, respectively. The main grill fixing end 271 is formed in a hook shape, and is formed to protrude rearward on the left and right sides of the rear center of the grill plate 270, respectively. As the main grill fixing end 271 is fixed inside the storage space 121, the grill plate 270 may be firmly fixed to the storage space 121.

Referring to FIG. 18, an air inlet hole 275 and a discharge portion (not shown) are formed in the front surface 270a of the grill plate 270. The air inlet hole 275 is a part through which the air of the storage space 121 is introduced into the cooling chamber 125, and the discharge part is a part through which the air of the cooling chamber 125 is discharged to the storage space 121.

An air inlet 272 is formed under the front surface 270a of the grill plate 270. The air inlet 272 is formed of a wall and is elongated to the left and right, and protrudes in the direction of the storage space 121. That is, the air inlet 272 is depressed in a direction away from the inner surface 124 (refer to FIG. 18) facing the grill plate 270 from the inner case 120. Accordingly, the air inlet 272 may form a space between the evaporator 630 and away from the evaporator 630.

In addition, an air inlet hole 275 is disposed below the air inlet 272 to prevent water droplets from flowing into the air inlet hole 275 to be described later through the front side of the grill plate 270. Since the air inlet 272 protrudes in the direction of the storage space 121, water droplets generated due to a temperature difference on the front portion of the grill plate 270 fall downward and flow into the air inlet hole 275. It is to play a role to prevent.

Next, a grill fan module 500 of a refrigerator according to an embodiment of the present invention will be described in detail with reference to FIGS. 17 and 18. A grill fan module 500 is installed on the rear surface 270b of the grill plate 270. The grill fan module 500 includes a shroud 510 and a grill fan member 550.

First, referring to FIG. 18, the inner surface 124 facing the grill pan module 500 from the inner case 120 constituting the cabinet 100 is recessed so that the distance with the grill pan module 500 is increased. The portion 124' is recessed, and the grill fan module 500 is installed to face the avoidance recessed portion 124', so that a sufficient air flow space is secured therebetween. For reference, reference numeral 124 ″ in FIG. 16 denotes an installation depression recessed in a portion corresponding to the rear of the accumulator 639 in the inner surface 124 of the inner case 120.

The shroud 510 of the grill fan module 500 has a guide wall 520, and there is a shroud fixing part 522, so that the grill fan module 500 is assembled to the rear surface 270b of the grill plate 270. Can be.

In addition, a grill fan member 550 is installed on the shroud 510. Various grill pans may be applied to the grill pan member 550, but in this case, an axial fan type grill pan will be applied.

Next, the air conditioning module 600 will be described with reference to FIGS. 6 to 10 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 an evaporator 630. 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, ie, in the suction space (I), of both sides divided by the separation partition wall 230 in the machine room frame 200, and the compressor 610 is It is located in the discharge space (O), which is a part through which the air that has passed through the main condenser 620 passes.

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 adjacent to the inlet 225a in the front of the machine room 201, and the compressor 610 is on the rear side in the machine room 201 (the side adjacent to the rear plate 213) Is located in 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 fan 611 is continuously installed from the separation partition wall 230 described above.

In this way, the compressor 610 and the radiating fan 611 are spaced apart from the inside of the machine room 201 and installed in front of the rear plate 213. In this case, components having a height higher than that of other components can be concentrated behind the machine room 201, and by installing the remaining components in the front, at least the front of the machine room 201 can be lowered in height.

In addition, the storage space 121 of the refrigerator may be increased by lowering the height in front of the machine room 201. Referring to FIG. 3, there is an avoidance part 123 on the bottom surface of the storage space 121, below the avoidance part 123 is a compressor 610 and a heat dissipation fan 611, and the avoidance part 123 You can use the space in front of

At this time, the compressor 610 and the heat dissipation fan 611 are disposed so that at least a portion of the compressor 610 and the heat dissipation fan 611 overlap each other along a direction orthogonal to a direction in which the inlet 225a and the outlet 225b are opened. Referring to FIG. 8, the compressor 610 and the heat dissipation fan 611 are both disposed close to the rear plate 213, but are installed side by side in the left and right directions.

In this embodiment, as shown in FIG. 8, the compressor 610 and the heat dissipation fan 611 are installed to face each other in front of the rear plate 213. In particular, the extending direction of the rotating shaft of the radiating fan 611 is toward the compressor 610 so that most of the radiating fan 611 overlaps with the compressor 610. According to this structure, referring to FIG. 9, when viewed from the side, the heat dissipation fan 611 covers most of the compressor 610. Therefore, the large-sized compressor 610 and the heat dissipation fan 611 are disposed on the same line inside the machine room 201, and the front side thereof can be used as a storage space 121 or used as a space for installing other parts. .

And, looking at Figures 7 and 8, the heat dissipation fan 611 is spaced apart from the side plate 212 of the machine room frame 200 extending along one side of the suction port (225a) between the side plate 212 To create an air flow space connected to the inlet (225a). Here, the air flow space can be viewed from the top of the defrost water tray 240 corresponding to the left side of the air flow guide 245 described above when viewed with reference to FIG. 8.

At this time, the extending direction of the rotational axis of the heat dissipating fan 611 is formed orthogonal to the direction in which the suction port 225a is opened. That is, the heat dissipation fan 611 faces the compressor 610 in front. Accordingly, the air flow space can be relatively widened. If the heat dissipation fan 611 faces the main condenser 620 or is installed at an angle, the width of the air flow space is inevitably narrowed, and the air flow is not smooth.

In addition, as the heat dissipation fan 611 faces the compressor 610 in front, a strong wind is injected from the heat dissipation fan 611 toward the compressor 610 to effectively cool the compressor 610.

In this way, the heat dissipation fan 611 is a very important component to perform a cooling function through suction of air and discharge of air, and cooling performance may be improved as the size increases. Referring to FIG. 9, in this embodiment, since the heat dissipation fan 611 is parallel to the compressor 610, a heat dissipation fan 611 having a height corresponding to the height of the maximum compressor 610 may be applied. That is, the height H2 of the heat dissipation fan 611 is equal to or smaller than the height H1 of the compressor 610.

Meanwhile, the compressor 610 is disposed on a path in which the outlet 225b is opened. Accordingly, the air heated through the compressor 610 may flow directly toward the discharge port 225b and be discharged to the outside. The compressor 610 may be entirely or at least partially disposed on a path in which the outlet 225b is opened.

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 pipe L2 is installed in the defrost water tray 240 and is located close to the bottom surface 241 ′ of the defrost water tray 240. The evaporation pipe L2 is installed to be spaced apart from the bottom surface 241 ′ of the defrost water tray 240 by a predetermined distance, and is connected in a zigzag direction as shown in FIG. 6 to secure the maximum length. The evaporation pipe (L2) is connected to the refrigerant discharge pipe (610a, see Fig. 8) of the compressor 610 through the main control valve 625, and is a passage through which high-pressure/high-temperature refrigerant passes. Since it is disposed close to the bottom surface 241 ′ of, 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 evaporator 630 through a fifth connection pipe L9. The evaporator 630 is 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 air is sucked from the lower side of the storage space 121 by the operation of the grill fan modules 500a and 500b, the air is discharged to the upper side of the storage space 121, and the air is transferred to the evaporator 630. ) To allow heat exchange while passing through.

The evaporator 630 is composed of a plate-shaped evaporator 630 so that it can be stably installed in front of the rear side wall of the inner case 120 while improving heat exchange performance in a narrow space. Reference numeral L10 denotes an evaporator connection pipe connecting the evaporator 630 and the main control valve 625.

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

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

Next, the evaporator 630 will be described with reference to FIGS. 16 to 18. The refrigerant in a high-temperature and high-pressure state while passing through the compressor 610 and the main condenser 620 installed in the machine room 201 becomes a liquid state in which the pressure and temperature are lowered through the throttling action of the capillary tube. , In this state, it is transmitted to the evaporator 630. In addition, the evaporator 630 serves to lower the temperature inside the storage space 121 by using latent heat while receiving the low-temperature, low-pressure liquid refrigerant and evaporating the refrigerant into a gas.

The expansion valve lowers the pressure with a low-temperature, low-pressure liquid refrigerant gas so that the high-temperature and high-pressure refrigerant gas discharged from the main condenser 620 is easily evaporated in the evaporator 630, and adjusts the flow rate of the refrigerant gas to the evaporator 630. ) To discharge. The expansion device for the refrigerating chamber may include a capillary tube. The capillary tube has a relatively small diameter, and during the process of passing the refrigerant through the capillary tube, the refrigerant may expand by acting as a resistance against the flow of the refrigerant.

In this embodiment, the evaporator 630 is installed in the cooling chamber 125. More precisely, as shown in FIG. 18, a cooling chamber made between the inner surface 124 of the inner case 120 and the grill plate 270 ( 125). In addition, the grill fan module 500 described above is positioned above the evaporator 630 so that the grill fan module 500 sucks air in the storage space 121 through the lower side, that is, the air inlet hole 275, After passing through the evaporator 630, it is discharged into the storage space 121 again through the upper discharge part.

Looking at the configuration of the evaporator 630, the evaporator 630 includes a cooling pipe 638 through which a refrigerant flows and a cooling fin 650 through which the cooling pipe 638 passes. The cooling pipe 638 may be viewed as a kind of long pipe. It is connected to the capillary tube (expansion valve) described above to receive the refrigerant, and discharges the refrigerant that has passed through the evaporator 630 again.

To this end, the cooling pipes 638 are configured as a pair. More precisely, the cooling tube 638 includes a first cooling tube 638a and a second cooling tube 638b. Here, the first cooling tube 638a is a part into which the refrigerant supplied from the capillary tube (expansion valve) flows in, and it continuously passes through the pinholes 653a and 653b of the cooling fin 650 to be described below, and is cooled at the outermost side. Pass through to the pin 650.

In addition, the second cooling pipe 638b is connected to the first cooling pipe 638a and also continuously passes through the pinholes 653a and 653b of the cooling fin 650. The first cooling pipe 638a and the second cooling pipe 638b are connected to each other by changing directions from the outside of the cooling fins 650 disposed at the outermost of the plurality of cooling fins 650. That is, the first cooling pipe 638a and the second cooling pipe 638b are not configured as separate units, but one pipe is connected continuously, but the direction is changed in the middle.

An accumulator 639 is installed in the middle of the second cooling pipe 638b. A refrigerant absorbing surrounding heat is transmitted to the accumulator 639 through the second cooling pipe 638b. The accumulator 639 separates the unvaporized liquid refrigerant from the delivered refrigerant so that the liquid refrigerant is not transferred to the compressor 610.

Looking at the configuration of the cooling fins 650, the cooling fins 650 are configured in a row at the rear of the storage space 121, that is, inside the cooling chamber 125. A plurality of cooling fins 650 are arranged side by side to constitute the evaporator 630, but these cooling fins 650 do not constitute a plurality of rows by different heights. In this embodiment, the refrigerator is composed of only one row to enable miniaturization. In addition, in this embodiment, since the refrigerator is a refrigerator for storing alcoholic beverages such as wine, a refrigeration function is not required, and since the range of the refrigeration set temperature is narrow, a plurality of rows of cooling fins 650 are unnecessary. Of course, unlike this, the cooling fins 650 may constitute two or more rows.

The cooling fins 650 are made in the shape of a thin metal plate, and are composed of a plurality of cooling fins 650 to be advantageous in heat exchange with the surrounding air. In addition, between the cooling fins 650 are spaced apart for the flow of air.

Pinholes 653a and 653b (refer to FIG. 18) are formed in the cooling fins 650, and the pinholes 653a and 653b are a first cooling pipe 638a and a second cooling pipe constituting the cooling pipe 638. It is configured in a pair so that each 638b passes through. More precisely, the pinholes 653a and 653b are disposed in the cooling fin 650 in the vertical direction. As a result, the cooling pipes 638 are disposed in two rows while passing through the upper and lower portions of the cooling fins 650, respectively.

In contrast, three or more pinholes 653a and 653b may be provided in the cooling fin 650, and the cooling pipe 638 may pass through the pinholes 653a and 653b in a zigzag form. Alternatively, only one pinhole 653a and 653b may be present in the cooling fin 650. In this case, the cooling pipe 638 does not pass through the pinhole when it returns to the opposite direction after passing through the one pinhole 653a. In this case, since there is a possibility of rotation of the cooling fins 650, the number of the pinholes 653a and 653b is preferably at least two or more. In addition, since the cooling fin 650 has two pinholes 653a and 653b in general, the existing cooling fin 650 may be used as it is.

In this embodiment, the cooling fins 650 are installed in an erect direction. That is, the cooling fins 650 are disposed in a direction in which the cooling fins 650 are erected so that the height is greater than the width. Here, the width of the cooling fins 650 refers to the left and right lengths based on FIG. 18, and the height refers to the upper and lower lengths. In this case, the left and right widths occupied by the cooling chamber 125 may be smaller than that of the cooling fins 650 installed in a lying state. Accordingly, the entire left and right width of the cooling chamber 125 may be reduced, and conversely, the storage space 121 may be wider.

In this embodiment, the cooling fin 650 is vertically erected along the direction of gravity, but it is not necessarily limited thereto. The cooling fins 650 may be erected inclined to have a predetermined angle. Of course, considering the left and right widths of the cooling chamber 125, it is most preferable to erect vertically as shown in FIG. 18.

Pinholes 653a and 653b are formed in the cooling fins 650. In this embodiment, the pinholes 653a and 653b are formed of a pair of an upper pinhole 653a and a lower pinhole 653b. These upper pinholes 653a and lower pinholes 653b are formed in the cooling fins 650 at different heights, and one cooling tube 638 passes through the two pinholes 653a and 653b, respectively. do.

At this time, the plurality of cooling fins 650 are arranged side by side so that the pinholes 653a and 653b have the same height as the pinholes 653a and 653b of the other cooling fins 650 adjacent to each other. Therefore, one cooling pipe 638 continuously passes through the pinholes 653a and 653b of the same height, and the cooling pipe 638 passing through the pinholes 653a and 653b of the outermost cooling fin 650 The silver may extend through different pinholes 653a and 653b having different heights by changing the direction.

For example, of the cooling pipes 638, the first cooling pipe 638a passes through the upper pinholes 653a in succession, and then the direction around the pinholes 653a and 653b of the outermost cooling fins 650 By changing it, it becomes the second cooling pipe 638b and passes through the lower pinholes 653b. At this time, the first cooling pipe 638a and the second cooling pipe 638b are connected through the joint 660 bent in a substantially U shape around the outermost cooling fins 650.

In this way, the first cooling pipe 638a and the second cooling pipe 638b pass through the cooling fins 650 while having different heights from each other. Therefore, the cooling fin 650 does not rotate arbitrarily and can maintain a stably erected state. That is, the cooling pipe 638 constitutes a kind of fixing structure of the evaporator 630 together with the evaporator holder 640 to be described below.

At this time, the first cooling pipe 638a passes through the upper pinhole 653a, and the second cooling pipe 638b passes through the lower pinhole 653b. In this case, the cooling pipe 638 first passes through the upper portion of the cooling fin 650 having a relatively low temperature, and then passes through the lower portion. Accordingly, it is possible to effectively reduce the occurrence of frost in the lower portion of the cooling fins 650 in which contact with air with high humidity delivered from the storage space 121 is relatively larger.

Meanwhile, in some regions of the evaporator 630, the second cooling fins 652 are disposed with a relatively wider interval than the first cooling fins 651 in other regions. Referring to FIG. 16, among the plurality of cooling fins 650 constituting the evaporator 630, the second cooling fins 652 connected to the initial inlet of the first cooling pipe 638a are arranged with a relatively wide interval. It becomes. This is to allow the remaining ice or defrost water to flow downward by disposing the second cooling fins 652 in a region where residual ice or defrost water mainly falls.

On the other hand, there are evaporator holders 640 at both ends of the evaporator 630. The evaporator holder 640 is erected in the same direction as the cooling fin 650 and fixes the evaporator 630 to the inner surface 124 of the inner case 120.

Specifically, the evaporator holder 640 has a holder body that is erected in parallel with the cooling fins 650 to form a skeleton. The holder body has a substantially thin plate shape and may be made of a metal material. The holder body is erected in parallel with the cooling fins 650 and has a larger area than the cooling fins 650. Accordingly, the evaporator holder 640 may protect the cooling fins 650 on the left and right sides of the evaporator 630.

The holder body has a strength reinforcing rib 642. The strength reinforcing rib 642 is formed by being bent in the holder body. The strength reinforcing rib 642 of the evaporator holder 640 extends along the longitudinal direction of the evaporator holder 640. That is, the strength reinforcing rib 642 is provided along the relatively long portion, so that the strength of the evaporator holder 640 may be reinforced. Since the evaporator holder 640 is made in a thin plate shape, it can be easily deformed or bent by an external force, and the strength reinforcing rib 642 prevents the evaporator holder 640 from bending.

At this time, the strength reinforcing ribs 642 of the evaporator holder 640 extend along the longitudinal direction in which the evaporator holder 640 is erected at both ends of the evaporator holder 640. That is, the strength reinforcing ribs 642 extend in parallel on both sides of the evaporator holder 640, and are formed in a direction in which the evaporator holder 640 is erected. Through this structure, the durability of the evaporator holder 640 may be further increased.

The evaporator holder 640 is configured as a pair on both sides of the evaporator 630, and may have the same structure. As shown in FIG. 19, the pair of evaporator holders 640 are of the same height, and the direction in which the strength reinforcing ribs 642 protrude is the same. Therefore, since the distance between the pair of strength reinforcing ribs 642 is larger than the width of the cooling fins 650, the evaporator holder 640 and the cooling fins 650 may not interfere with each other. In addition, since the pair of evaporator holders 640 are of the same shape, facilities and processes for manufacturing the evaporator holders 640 can be unified.

The holder body has a fixing hook (645). The fixing hanger 645 is a portion protruding in the shape of a hook, extending from the holder body, and being hooked and fixed to the inner case 120 of the cabinet 100. As shown in FIG. 21, the inner surface 124 of the inner case 120 has a fixing groove 129 through which the fixing hook 645 is hooked, so that the fixing hook 645 can be hooked.

Meanwhile, referring to FIG. 18, there is an air inlet 272 through which air of the storage space 121 is introduced under the grill plate 270 in which the grill fan module 500 is installed, and the air inlet 272 ) Is formed to overlap the height of the cooling fins 650 of the evaporator 630 in at least some sections.

At this time, the air inlet 272 protrudes in the direction of the storage space 121, that is, away from the inner surface 124 of the inner case 120 so as to be away from the evaporator 630, so that the air inlet 272 ) And the evaporator 630, a blank space is naturally created. Accordingly, air can be smoothly introduced through the air inlet hole 275 in the air inlet 272.

In particular, the air inlet hole 275 of the air inlet portion 272 is formed to be inclined toward the cooling fin 650. More precisely, the air inlet hole 275 is inclined upward to face the cooling fin 650, so that the air in the storage space 121 can be accurately supplied to the evaporator 630.

In addition, the inner surface 124 facing the grill fan module 500 from the inner case 120 has an avoidance depression 124' recessed so that the distance with the grill fan module 500 is increased, and the evaporator 630 ) Is installed below the avoidance depression 124'. Accordingly, smooth air flow is possible in the order of the air inlet hole 275-the evaporator 630-the avoidable depression 124 ′-the grill fan module 500.

Next, the control module 700 will be described with reference to FIGS. 19 to 21, 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. 19 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. 21, 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. 20 and 21, 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.

21, 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.

21, 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. 19, when the suction and 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 discharge space O 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. 19, the control module 700 is installed inside the machine room 201 in a lying state. Therefore, since the main control board 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, it can be stably accommodated even if the main control board is not fixed with a separate fastener. I can. Of course, it is also possible to fix the main control board 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. Accordingly, the area of the main control board 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 (not shown). 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. Referring to FIG. 20, 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.

Referring to FIG. 20, the storage case 710 is provided with protective walls 712 and 713. The protective walls 712 and 713 protrude along the edge of the storage case 710 to surround the storage space 701, and the height of the protective walls 712 and 713 becomes the height of the storage case 710.

The protective walls 712 and 713 include a rear wall 712 facing the inside of the machine room 201 and a front wall 713 facing the outside, and have a guide end 715 along a side surface. 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 surface of the storage case 710 so that the first guide channel of the installation rail 260 ( It is fitted into 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 of the storage case 710. That is, the guide end 715 is provided along the upper end of the side surface, and protrudes outward from the upper end of the side surface. As the guide end 715 is provided at the upper end of the side surface, the storage case 710 may be installed to be in close contact with the bottom surface 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 and 713 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 is accommodated at the center, 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 and 713.

A wire harness (not shown) connected to the main control board 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 peripheral parts including parts of the main control board, and these can be arranged through the wire connection space 702. 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 and 713. Accordingly, the partition wall 720 may filter once more foreign matter is introduced into the main control board.

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 door opening device 900 will be described with reference to FIGS. 22 to 24. First, the door opening device 900 is installed in the installation space 253 recessed in the direction of the storage space 121 from the bottom of the cabinet 100. Here, the installation space 253 has a shape in which a lower part of the cabinet 100 is recessed, and in this embodiment, the installation space 253 is made in the cover plate 250.

That is, a cover plate 250 is installed between the upper portion of the machine room frame and the lower portion of the cabinet 100 to cover the machine room 201, and the door opening device 900 is the bottom surface of the cover plate 250 ( It is accommodated in the installation space 253 recessed toward the lower portion of the cabinet 100 at 251.

At this time, since the cover plate 250 is spaced apart from the inner case 120 to create a foaming space therebetween, a foaming agent is filled above the cover plate 250 to make a heat insulation part. Accordingly, the installation space 253 is depressed toward the space of the heat insulating portion, and there is no fear of interference with other parts. In addition, the periphery of the cover plate 250 surrounding the door opening device 900 is filled with a heat insulating part, and this heat insulating part also serves as a sound insulating material that blocks the operating noise of the motor/gear generated in the door opening device 900.

Referring to FIG. 22, the installation space 253 is made inside the recessed portion recessed from the cover plate 250 toward the bottom of the inner case. The installation space 253 is in the center of the cover plate 250, and the installation space 253 has a bottom surface facing the machine room and a front surface facing the door assembly, respectively.

That is, the installation space 253 can be viewed as a space connected to the machine room 201. Therefore, when the machine room assembly is separated from the refrigerator, the installation space 253 and the door opening device 900 installed in the installation space 253 are externally As it turns out, it can also be easily maintained. 22 shows the bottom of the refrigerator after removing the machine room assembly of the refrigerator, and it can be seen that the installation space 253 and the door opening device 900 installed in the installation space 253 are exposed.

In addition, the front of the installation space 253 toward the door assembly 130 is also open. Referring to FIG. 24, a front entrance 253' of the installation space 253 is exposed. At this time, the front of the installation space 253 is shielded by a front frame 118 constituting the cabinet 100, and a push rod 950 protruding from the door opening device 900 on the front frame 118 There is a rod entry and exit 119 of the.

Therefore, the front surface of the installation space 253 is shielded by the front frame 118, and only the portion where the push rod 950 enters and exits is drilled in the form of a hole. Therefore, in a state in which the push rod 950 of the door opening device 900 has not yet protruded, the load cap 952 of the push rod 950 blocks the rod inlet 119 to prevent foreign substances from flowing into the inside.

Referring now to the structure of the door opening device 900 with reference to FIG. 24, the door opening device 900 is installed in a device case 901 forming an external shape. A portion of the device case 901 close to the door assembly 130 is narrow, but the inner portion of the cover plate 250 is relatively wide. This is according to the arrangement of the drive motor 910 and the gear assembly 920 installed in the device case 901, which will be described again below.

The device case 901 is installed at the center of the cover plate 250, and more precisely, the rod inlet 119 from which the push rod 950 protrudes is preferably located on the center line of the cover plate 250. Do. For reference, A in FIG. 22 represents the center line of the cover plate 250.

Referring to FIG. 24, the device case 901 has a height corresponding to the installation space 253 and has a thin and wide plate-shaped structure. The device case 901 may be composed of a plurality of parts. For example, an upper case (not shown) and a lower case form the outer shapes of the upper and lower portions of the door opening device 900, respectively. Further, the upper case and the lower case are coupled to provide a space in which the driving motor 910 and the gear assembly 920 can be disposed. In the drawing, the upper case is omitted so that the driving motor 910 and the gear assembly 920 are exposed. Of course, the upper case may be omitted and the device case 901 may be configured only with the lower case.

There are a plurality of installation rings 905 outside the device case 901. The installation ring 905 is inserted into the ring mounting groove 904 recessed at the edge of the device case 901, and the mounting ring 905 includes the lower case being the ring mounting groove 904 of the device case 901. By supporting so as to be seated on the inside, it may be formed of a silicon material. Accordingly, it is possible to attenuate vibration generated when the door opening device 900 is driven, and has a structure capable of preventing noise due to this.

A drive motor 910 is installed in the device case 901. The driving motor 910 is mounted on the lower surface of the device case 901. The driving motor 910 may be a BLDC type motor capable of both forward and reverse rotation. As the driving motor 910 uses a BLDC type motor, it is possible to variably control the speed of the driving motor 910 by counting a frequency generating (FG) signal.

Accordingly, the impact when the door assembly 130 is opened or closed may be alleviated through speed control during the operation of the door opening device 900. In addition, emergency return of the push rod 950 can be performed in an emergency situation. The driving motor 910 is mounted on a lower surface of the lower case, and a rotation shaft of the driving motor 910 may penetrate inside the lower case.

A drive motor 910 is installed in the device case 901, and a pinion gear 911 of the drive motor 910 protrudes to rotate by the drive motor 910. In addition, the pinion gear 911 meshes with the gear assembly 920 to rotate the gear assembly 920. Specifically, a plurality of gears are arranged in the device case 901 to mesh with each other, and the plurality of gears include reduction gears 921 and 923 and spacer gears 925 and 927. Here, the reduction gears 921 and 923 play a role of reducing the rotational speed of the drive motor 910 through a gear ratio, and the spacer gears 925 and 927 are connected to and meshed with the reduction gears 921 and 923, but the push rod 950 and the reduction gear ( 921,923).

The first reduction gear 921 is connected to the second reduction gear 923, and the second reduction gear 923 is connected to the spacer gears 925 and 927. The reduction gears 921 and 923 have a structure in which the input side and the output side are arranged in two stages, like the general reduction gears 921 and 923, and are configured so that the adjacent gear, the input side, and the output side come into contact with each other to reduce the speed.

The number of revolutions can be adjusted through a combination of the plurality of reduction gears 921 and 923, and the force transmitted to the push rod 950 can be adjusted through the adjustment of the number of revolutions. Of course, the number of reduction gears 921 and 923 may be adjusted as necessary. In this embodiment, the reduction gears 921 and 923 are composed of a total of two, but may be three or more. Reference numerals 921' and 923' denote rotation axes of the first reduction gear 921 and the second reduction gear 923, respectively.

A first spacer gear 925 is disposed on the second reduction gear 923, and the first spacer gear 925 and the push rod 950 may be connected by a second spacer gear 927. The spacer gears 925 and 927 have a general spur gear shape and simply transmit the force of the second reduction gear 923 to the push rod 950, but adjust the contact distance with the push rod 950 to adjust the push rod ( It is configured to secure the maximum withdrawal distance of 950). To this end, the spacer gears 925 and 927 may be composed of a plurality of gears having different sizes.

In addition, the position of the contact point between the spacer gears 925 and 927 and the push rod 950 for transmitting power to the push rod 950 is preferably arranged in the withdrawal direction of the push rod 950 as much as possible, and the door It should be located at a position close to the rear surface of the assembly 130. To this end, spacer gears 925 and 927 are disposed between the second reduction gear 923 and the push rod 950. Reference numerals 925' and 927' denote rotation axes of the first spacer gear 925 and the second spacer gear 927, respectively.

Specifically, the reduction gears 921 and 923 constituting the gear assembly 920 of the door opening device 900 and the spacer gears 925 and 927 are arranged in different directions. 23 and 24, a direction X in which a plurality of reduction gears 921 and 923 extend from the driving motor 910 of the door opening device 900 and the plurality of spacer gears 925 and 927 are the reduction gears. The directions Y extending from the (921,923) are formed differently from each other.

In this embodiment, a direction X of the plurality of reduction gears 921 and 923 constituting the gear assembly 920 of the door opening device 900 extends from the drive motor 910 of the door opening device 900 is the door opening device. The direction Y is substantially perpendicular to the direction in which the push rod 950 of the push rod 950 enters and exits, and the direction Y in which the plurality of spacer gears 925 and 927 extend from the reduction gears 921 and 923 is a direction in which the push rod 950 enters and exits. Side by side

As such, when the direction Y in which the spacer gears 925 and 927 are extended is parallel to the direction in which the push rod 950 enters and exits, the contact of the second spacer gear 927 meshing with the push rod 950 is maximized at the load inlet and outlet. It may be close to 119, through which it is possible to secure the maximum withdrawal distance of the push rod 950. At the same time, by changing the arrangement direction of the reduction gears 921 and 923 and the arrangement direction of the spacer gears 925 and 927, the gear assembly 920 extends long in only one direction, thereby excessively increasing the overall length of the door opening device 900. Can also be prevented.

The push rod 950 may open the door assembly 130 by pushing the rear surface of the door assembly 130. In addition, the push rod 950 is mounted on the inside of the device case 901, and a rack gear is formed on the outer surface so as to be engaged with the second spacer gear 927 to be operated. Accordingly, the rack gear may protrude through the rod inlet 119 by the rotation of the spacer gears 925 and 927. Due to the position of the second spacer gear 927, at least half of the rack gear is pulled out of the device case 901 when the push rod 950 is operated by the second spacer gear 927 Can be.

In this embodiment, the push rod 950 has an arc shape having a predetermined curvature. Accordingly, even when the door assembly 130 is rotated, the push rod 950 can maintain a certain point on the rear surface of the door assembly 130, more precisely, in a state in contact with the contact jaws B. Accordingly, even when the door assembly 130 is rotated, the push rod 950 does not slip and pushes a point of the door assembly 130 to open the door assembly 130.

A rod cap 952 is provided at a front end of the push rod 950. The load cap 952 may be made of an elastic material such as silicone or rubber, and is in contact with the door assembly 130 to prevent noise when the push rod 950 and the door assembly 130 come into contact with each other, and to increase gripping force. It is improved so that the force pushed by the push rod 950 can be effectively transmitted to the door assembly 130.

In this embodiment, the front surface of the load cap 952 facing the rear surface of the door assembly 130 is wider than the end of the push rod 950, so that the surface B'of the contact jaw B is more stable. I can push it. The load cap 952 has a substantially rectangular front surface.

At this time, in this embodiment, the control module 700 is located close to the door opening device 900. A control module 700 is installed on the bottom surface 251 of the cover plate 250 to be electrically connected to the door opening device 900. That is, the control module 700 is installed on the bottom surface 251 of the cover plate 250, but when the cabinet 100 and the machine room frame are combined, it is located inside the machine room. Can be placed very close.

More specifically, the control module 700 is located oriented toward the side of the machine room so as to be adjacent to the outlet of the machine room, and the door opening device 900 is positioned higher from the floor of the machine room than the control module 700. have. This is because the control module 700 is installed on the bottom surface 251 of the cover plate 250, but the door opening device 900 is an installation space that is further recessed from the cover plate 250 toward the bottom surface of the cabinet 100. Because it is installed in (253). Of course, due to the height difference, the possibility of interference between the control module 700 and the door opening device 900 may be lowered.

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.

Referring to FIG. 25, the high-temperature, high-pressure refrigerant compressed by the compressor 610 passes through the evaporation pipe L2 (in the direction of arrow ①). The evaporation pipe L2 is installed in the defrost water tray 240, and the maximum In order to secure a longer length, they are connected in a zigzag direction as shown in FIG. 25. The evaporation pipe (L2) is connected to the refrigerant discharge pipe (610a, see Fig. 8) of the compressor 610 through the main control valve 625, and is a passage through which high-pressure/high-temperature refrigerant passes. Since it is disposed close to the bottom surface 241 ′ of, it may serve to evaporate the defrost water accumulated in the defrost water tray 240.

Subsequently, the refrigerant is delivered to the main condenser 620 and condensed. (See ②) The main condenser 620 is disposed close to the inlet of the suction space I, and after condensing the refrigerant, it is delivered to the expansion valve (capillary tube). do.

In this embodiment, since the first side condensation pipe L4 is connected to the main condenser 620, the refrigerant first passes through the first side condensation pipe L4 (in the direction of arrow ③), and then the first side condensation pipe L4. Since the pipe L4 is connected to the second side condensation pipe L6 through the third connection pipe L5 crossing the machine room 201, the refrigerant condenses while passing through the second side condensation pipe L6. (Arrow ④ direction) As described above, in the present invention, since the side condensing pipes L5 and L6 exist, the side condensing pipes L5 and L6 assist the main condenser 620 to condense the refrigerant together, and the main condenser The size of 620 can be made relatively small.

And the side condensing pipes (L5, L6) are built inside the side of the cabinet 100 to increase the side temperature of the refrigerator, thereby preventing the phenomenon of dew condensation on the outer surface of the refrigerator due to the temperature difference between the inside and the outside of the refrigerator. You may.

Meanwhile, since the second side condensation pipe L6 is connected to the front condensation pipe L8 through the fourth connection pipe L7, the refrigerant can be condensed even in the process of passing through the front condensation pipe L8. ⑥ direction) As such, in this embodiment, the first side condensing pipe (L4), the second side condensing pipe (L6), and the front condensing pipe (L8) perform a condensing function of the refrigerant together with the main condenser 620, respectively. Therefore, even if the height of the machine room 201 is low and narrow, it is not possible to install a large main condenser 620 in the machine room 201, it is possible to compensate for this.

The refrigerant passing through the front condensation pipe L8 is delivered to the expansion valve through the fifth connection pipe L9, and the refrigerant whose pressure and temperature have fallen from the expansion valve is delivered to the evaporator 630. Although not shown, a dryer and a capillary tube are further installed between the front condensing pipe L8 and the evaporator 630, and the front condensing pipe L8-dryer-main control valve 625-capillary tube (Capillary Tube)-The refrigerant flows in the order of the evaporator 630. Here, the dryer serves to protect the system by trapping moisture and foreign substances, and the capillary tube acts as throttling.

Meanwhile, the evaporator 630 is disposed in a space at the rear side of the grill fan modules 500a and 500b among each portion of the inner case 120. That is, when air is sucked from the lower side of the storage space 121 by the operation of the grill fan modules 500a and 500b, the air is discharged to the upper side of the storage space 121, and the air is transferred to the evaporator 630. ) To allow heat exchange while passing through.

26 shows a heat exchange process by the evaporator 630. First, there is a cooling chamber 125 partitioned from the storage space 121 at the rear of the storage space 121 (corresponding to the left space based on FIG. 26), and the evaporator 630 is installed in the cooling chamber 125 do. In addition, a grill fan module 500 is installed in the cooling chamber 125 corresponding to the upper portion of the evaporator 630 to suck the air delivered from the storage space 121 through the evaporator 630 It is discharged into the storage space 121 again.

More specifically, when the grill fan module 500 is operated, the grill fan module 500 sucks air from the lower portion of the evaporator 630. That is, the air inside the storage space 121 is introduced through the air inlet hole 275 in the air inlet 272 of the grill plate 270 (in the direction of arrow ①), and rises upward through the evaporator 630 Do it (in the direction of the arrow ②).

Here, the air inlet 272 protrudes away from the evaporator 630 in the direction of the storage space 121, that is, in a direction away from the inner surface 124 of the inner case 120, so that the air inlet 272 An empty space is naturally created between the and the evaporator 630. Accordingly, air can be smoothly introduced through the air inlet hole 275 in the air inlet 272.

At this time, the high-temperature, high-pressure air that has passed through the cooling pipe 638 of the evaporator 630 is changed into low-temperature and low-pressure air due to the cooling action of the cooling pipe 638. In particular, the air existing in the lower region of the cooling pipe 638 increases the flow velocity as it passes through the cooling fins 650, and the air pressure decreases as the flow velocity of air increases. Accordingly, air passing through the cooling fins 650 exhibits a lower pressure than before passing through the cooling fins 650.

Then, the air cooled in this way is discharged into the storage space 121 by the grill fan module 500 (in the direction of the arrow ③). In this process, the grill fan module 500 is viewed from the inner case 120. In the inner surface 124, an avoidance recess 124' is recessed so that the distance from the grill fan module 500 is increased, and the evaporator 630 is installed below the avoidance recession 124'. Accordingly, smooth air flow is possible in the order of the air inlet hole 275-the evaporator 630-the avoidable depression 124 ′-the grill fan module 500.

Meanwhile, defrost water is generated during the cooling process by the evaporator 630, and when the defrost water freezes, defrosting may occur. The generated defrost water flows downward in the direction of gravity and flows downward through the defrost water receiver 126 under the inner surface 124 of the inner case 120. In addition, the defrost water is collected in the defrost water tray 240 in the machine room 201 by riding the defrost water pipe 590.

The evaporator 630 is composed of a plate-shaped evaporator 630 so that it can be stably installed in front of the rear side wall of the inner case 120 while improving heat exchange performance in a narrow space. For reference, reference numeral L10 in FIG. 25 denotes an evaporator connection pipe connecting the evaporator 630 and the main control valve 625.

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

Meanwhile, FIG. 27 shows the air flow inside the machine room 201. During the flow of the refrigerant described above, the temperature of the machine room 201 rises. In particular, the temperatures of the compressor 610 and the main condenser 620 are greatly increased. In this embodiment, the temperature increase can be suppressed through the air flow inside the machine room 201.

Specifically, when the heat radiation fan 611 operates, the heat radiation fan 611 sucks outside air. Here, when air from the outside (where the refrigerator is installed) flows into the suction space (I) through the suction and discharge grill 220 (in the direction of arrow ①), the air immediately meets the main condenser 620. In particular, in this embodiment, the suction port 225a, which is the inlet of the suction space I, is wider than the discharge port 225b, which is the outlet of the discharge space O. That is, by widening the intake port 225a, the amount of air initially introduced is increased, and through this, the main condenser 620 can be effectively cooled.

At this time, the suction space I is blocked except for the suction port 225a, so that the introduced outside air may be concentrated only toward the heat dissipating fan 611 through the main condenser 620. Therefore, it is possible to more effectively cool the main condenser 620.

In addition, the introduced air may evaporate a part of the defrost water while passing over the defrost water tray 240 (in the direction of the arrow ②). At this time, the introduced air is guided by the separation partition wall 230. That is, the introduced air does not flow toward the exhaust space O including the compressor 610, but is guided toward the heat dissipation fan 611 along the separation partition wall 230. In this case, a heat dissipation fan 611 is installed at the rear end portion of the separation partition wall 230, so that the heat dissipation fan 611 becomes a part of a type of wall partition wall 230.

When the introduced air passes through the heat dissipation fan 611 (in the direction of arrow ③), it is discharged to the compressor 610 facing the heat dissipation fan 611 to cool the compressor 610. Since the heat dissipation fan 611 is open, the suction space I and the discharge space O are connected to each other based on the heat dissipation fan 611, but when the heat dissipation fan 611 is operated, air flows from the suction space I. Since it flows into the discharge space (O), it is difficult for air to flow in the opposite direction. Accordingly, it is possible to effectively prevent the heat of the compressor 610 from being transmitted to the main condenser 620.

At this time, there is a flow guide surface 245 between the defrost water tray 240 and the heat dissipation fan 611, so that the heat dissipation fan 611 is covered by the defrost water tray 240 and thus efficiency is prevented from deteriorating. That is, the introduced air is naturally guided toward the heat dissipation fan 611 through the downwardly inclined surface of the flow guide surface 245. The flow guide surface 245 may eliminate a kind of dead space that prevents air from flowing between the defrost water tray 240 and the heat dissipation fan 611 or generates a eddy current.

The air passing through the compressor 610 passes through the discharge space O. (in the direction of arrow ④) At this time, since the control module 700 is located above the discharge space O, the bottom surface of the control module 700 The discharge space (O) is formed between the bottom surface of the machine room frame 200 and air passes through this part. In FIG. 27, a portion through which air passes under the control module 700 is indicated by a dotted line.

Finally, the cooled air is discharged to the outside through the outlet 255b (in the direction of arrow ⑤). As described above, in this embodiment, since the introduced air flows only along a predetermined path, effective cooling is possible. In particular, the suction space (I) is blocked except for the suction port (225a), so the introduced outside air can be concentrated only in the direction of the heat dissipation fan 611 through the main condenser 620, whereas, after cooling, air Can be discharged in several directions.

That is, the discharge space (O) of the machine room 201 formed between the heat dissipation fan 611 and the discharge port 225b has a part of the bottom, side, or rear side of the heat dissipation hole 211 ′, 214, see FIGS. 7 and 11 ) To open and connect to the outside. Therefore, the initial inflow of outside air is limited to a specific direction, that is, toward the main condenser 620, but once the main condenser 620 and the compressor 610 are radiated, they can be discharged in various directions, thereby increasing the heat dissipation performance of the machine room. will be.
