Description

Refrigerator

In the present invention, in order to reduce logistics costs, after loading a refrigerator in a container, an additional refrigerator is installed in the remaining space at the top. This relates to a refrigerator with a structure that minimizes the flow of the compressor so that it can be loaded.

In general, a refrigerator is a device that discharges cold air generated by a refrigeration cycle consisting of a compressor, condenser, expansion valve, evaporator, etc. to lower the temperature inside the refrigerator to freeze or refrigerate food, etc.

Refrigerators generally include a freezer compartment for storing food or beverages at sub-zero temperatures and a refrigerator compartment for storing food or beverages at sub-zero temperatures.

Refrigerators include the Top Mount Type, where the freezer compartment is located at the top of the refrigerator compartment, the Bottom Freezer Type, where the freezer compartment is located at the bottom of the refrigerator compartment, and the Side By Type, where the freezer compartment and refrigerator compartment are partitioned to the left and right. It can be divided into Side By Side Type.

Among refrigerators that have a freezer and a refrigerator, there are refrigerators that open and close one storage space inside the cabinet with one door.

In a refrigerator that opens and closes with a single door, the door may be rotatably mounted on one side of the cabinet, and the freezer compartment may partition a portion of the storage space and have a separate freezer door mounted on the front thereof.

The freezer compartment may be partitioned from the refrigerating compartment by the freezer door and a partition wall to maintain a lower temperature than the refrigerating compartment that forms the remaining space of the storage space.

Meanwhile, recently, as eating habits change and user tastes become more diverse, there is a focus on larger and more multi-functional refrigerators. In response to this trend, the capacity of the storage compartment has been increased and the internal space is divided into left and right sides (side-door type). Byside type) Refrigerators are becoming more common. In this type of double-door refrigerator, storage compartments are formed on both sides based on a central partition, and two doors are hinged to the main body to open and close each storage compartment.

Patent Document 1 includes a support member forming the bottom, a pair of buffer members provided on both sides of the support member and supporting both sides of the bottom of the refrigerator to absorb the shock of the refrigerator, and a pair of buffer members combined with each other. It includes at least one horizontal reinforcing member so that the gap between the pair of buffer members corresponds to the width of the refrigerator, and a vertical reinforcing member provided on one side of the horizontal reinforcing member to prevent the support member from being deformed. A lower packaging material for a refrigerator configured as follows is disclosed.

Patent Document 1 has the advantage of being able to prevent the refrigerator from tipping over or falling due to deformation of the lower packaging material, allowing the refrigerator to be transported safely without causing property damage.

However, Patent Document 1 is a structure that simply holds the exterior of the refrigerator, and does not reflect a structure that minimizes damage caused by clearance of the compressor located in the machine room of the refrigerator.

Patent Document 2 relates to the packaging structure of the lower part of a refrigerator. The lower package of Patent Document 2 consists of a base made of corrugated cardboard, a plurality of supports arranged on the base, and cushioning materials located on both ends of the supports.

In addition, in Patent Document 2, the lower package includes a door support unit having a support contact part molded at the bottom so that the support sticks in close contact with the inside, and a cover support part molded on the upper side so that the central part of the front lower cover of the refrigerator hangs. It is installed between the refrigerator and the refrigerator. The front lower cover is supported by door supports at the center and by cushioning materials at both ends, preventing downward bending. In addition, an inclined surface is formed on the outer upper part of the door support, so that when the outer box is covered, the lower part of the outer box is guided to the outside of the door support, thereby facilitating the packaging work.

However, Patent Document 2 discloses a structure that simply supports the refrigerator door, but does not reflect a structure that minimizes damage caused by clearance of the compressor located in the machine room of the refrigerator.

On the other hand, when charging a refrigerator into a container, the refrigerator is loaded only in an upright position within the container, and the remaining space at the top inside the container is left empty, causing a problem of low loading efficiency.

Therefore, it is necessary to load the refrigerator standing within the container, and to load the refrigerator on its side to maximize the remaining space. The most problematic part at this time is pipe deformation (cracks, leakage) caused by the compressor flow within the refrigerator. , front end), the development of a structure to solve this is required.

Patent Application No. 10-2007-0114050 (published on May 13, 2009) Patent Application No. 10-1999-0053126 (published on June 15, 2001)

The present invention was developed to solve the above problems, and the purpose of the present invention is to provide a refrigerator with a structure that can load as many refrigerators as possible into a container in order to reduce logistics costs.

In addition, an object of the present invention is to provide a refrigerator structured to solve the problem that when charging a refrigerator into a container, the refrigerator is loaded only in an upright position within the container, and the remaining space at the top of the inside of the container is left empty, resulting in low loading efficiency. It is done.

In addition, the purpose of the present invention is to load the refrigerator standing in the container, and to make the best use of the remaining space, it is necessary to load the refrigerator lying down. The most problematic part at this time is the movement of the compressor in the refrigerator. We provide a refrigerator structured to solve pipe deformation (cracks, leakage, shearing).

In order to solve the above problems, the refrigerator of the present invention includes a cabinet having a machine room at the lower side; A compressor installed in the machine room and sagging in one direction due to its own weight when the refrigerator is laid down; a rear cover installed on the cabinet to form the rear of the machine room and including a spacer mounting portion; It may include a spacer that is installed on the spacer mounting part and supports the compressor in contact with it when the refrigerator is laid down.

According to an example related to the present invention, the spacer mounting portion may be formed at a position on the rear cover of the machine room that is contacted when the refrigerator is in a laydown state and sag occurs by a predetermined distance due to the self-weight of the compressor.

The spacer may have a rectangular shape with a chamfer at each corner.

The rear cover is provided with a plurality of heat dissipation guides having heat dissipation holes to discharge heat inside the machine room, and at least one heat dissipation guide may be disposed on both sides of the spacer mounting portion.

Preferably, the spacer may be made of EPDM (Ethylene Propylene Diene Monomer).

According to another example related to the present invention, the rear cover is provided with a deformation-prevention mounting portion on a surface opposite to the surface on which the spacer mounting portion is provided, and the deformation-prevention mounting portion includes a bottom portion on which the compressor is installed due to deflection of the compressor. A deformation prevention part is installed to reduce the maximum plastic strain applied to the cover, and the deformation prevention mounting part may be provided on an opposite side of the spacer mounting part with the rear cover interposed therebetween.

The rear cover is provided with a plurality of heat dissipation guides having heat dissipation holes to discharge heat inside the machine room, and at least one heat dissipation guide may be disposed on both sides of the deformation-resistant mounting portion.

Preferably, the deformation prevention part may be formed of EPDM (Ethylene Propylene Diene Monomer).

Preferably, the compressor may be a linear compressor.

According to another example related to the present invention, the compressor includes a bracket having a coupling hole coupled to the bottom cover of the machine room, and a coupling member including a coupling groove through which the bracket is coupled to the bottom cover of the machine room. can be provided.

For example, the coupling member may be a seat rubber.

The refrigerator of the present invention has a structure in which a spacer is installed on the rear cover of the machine room, so that when charging the refrigerator into a container, the refrigerator is loaded only in the upright position within the container, and the remaining space at the top inside the container is left empty, which reduces charging efficiency. You will be able to solve the problem.

Additionally, with the refrigerator of the present invention, logistics costs can be reduced by loading an additional refrigerator on top of the container.

In addition, the refrigerator of the present invention requires the refrigerator to be loaded standing within the container and to be loaded with the refrigerator lying down to maximize the remaining space. At this time, pipe deformation due to compressor flow within the refrigerator is the most problematic. (Cracks, leaks, shearing) problems can be solved.

In particular, the present invention can improve logistics costs by about 30% by loading 11 additional double-door refrigerators.

FIG. 1A is a conceptual diagram showing a loading space (a) in which the refrigerator 100 is loaded in the container 1 and a closed space (b) above the loading space (a), and FIG. 1B is a conceptual diagram showing the refrigerator 100 in the container 1. This is a conceptual diagram showing a loading space (a) where ) is loaded and a closed space (b) above the loading space (a).

Hereinafter, with reference to FIGS. 1A and 1B, the present invention will be described in relation to loading the refrigerator 100 into the container 1.

Referring to FIG. 1A, a plurality of refrigerators 100 are loaded in the lower loading space (a) inside the container 1. Referring to the drawings of the present invention, as an example, a double-door refrigerator 100 is shown, but it is not necessarily limited to the double-door refrigerator 100.

In addition, an example is shown in which a closed space (b) is formed in the upper part of the loading space (a) of the container 1 in FIG. 1A. In the case where the refrigerator 100 cannot be additionally loaded on the loading space (a), in FIG. 1A As in, if the space above the loading space (a) is not utilized, it becomes a closed space (b).

When loading the refrigerator 100 into the container 1, load the refrigerator 100 in the loading space (a) of the container 1 only with the refrigerator 100 standing upright, and leave the closed space (b) at the top inside of the container (1) empty. As a result, charging efficiency decreases and more containers 1 must be used to transport the refrigerator 100, thereby increasing logistics costs.

Therefore, the refrigerator 100 is loaded standing within the container 1, and in order to maximize the remaining space, the refrigerator 100 is laid down in the additional loading space c to allow loading. It is necessary, and the most problematic part at this time is pipe deformation (cracks, leakage, shear) caused by the flow of the compressor 20 in the refrigerator 100, and the development of a structure to solve this is required.

In addition, an example in which an additional loading space is formed at the top of the loading space (a) of the container 1 in FIG. 1B is shown. If the refrigerator 100 is additionally loaded in the additional loading space provided above the loading space (a), The space at the top of the loading space (a) can be utilized.

As shown in FIG. 1B, when the refrigerator 100 is loaded into the container 1, the refrigerator 100 is loaded in the loading space (a) of the container 1, and the refrigerator is placed in the additional loading space on the upper inner side of the container 1. By laying down (100), charging efficiency decreases, and since more containers (1) must be used to transport the refrigerator (100), logistics costs increase.

This is an enlarged view showing the compressor 20 spaced apart from the spacer 40.

Meanwhile, Figure 4c is a cross-sectional view showing an example in which the compressor 20 of Figure 3 is supported on the spacer 40 while coupled to the bottom cover 31 of the machine room 15, and Figure 4d is a cross-sectional view showing an example in Figure 4c. This is an enlarged view showing the compressor 20 supported on the spacer 40.

Hereinafter, the refrigerator 100 of the present invention will be described with reference to FIGS. 2 to 4D.

The refrigerator 100 of the present invention includes a cabinet 10 having a machine room 15 on the lower side, and a compressor 20 installed in the machine room and sagging in one direction due to its own weight when the refrigerator 100 is laid down. and a rear cover 30 installed on the cabinet 10 to form the rear of the machine room 15 and having a spacer mounting portion 30c, and installed on the spacer mounting portion 30c and a refrigerator 100. It includes a spacer 40 that contacts and supports the compressor 20 in a laid down state.

In the present invention, the laydown state of the refrigerator 100 means a state in which the refrigerator 100 is laid down with its side facing toward the bottom for stacking in the additional loading space c inside the container.

In the refrigerator 100 of the present invention, the maximum stress that the rear cover 30 can withstand in a laydown state is further increased due to the structure in which the spacer 40 is mounted, thereby enhancing durability.

Additionally, a machine room 15 is formed at the rear of the bottom of the cabinet 10 to accommodate a compressor 20, which is a component of the refrigeration cycle.

Specifically, inside the machine room 15, a compressor 20 that compresses the refrigerant, a condenser (not shown) through which the refrigerant discharged from the compressor 20 flows, and a condensation fan for cooling the condenser may be accommodated. there is.

In the present invention, the refrigerator 100 is loaded standing within the container 1, and in order to maximize the remaining space, the refrigerator 100 needs to be loaded lying down. At this time, the refrigerator 100 is the most problematic part. This is to solve pipe deformation such as cracks, leakage, and shear caused by the flow of the compressor (20) in (100).

In particular, in the present invention, in a laydown state in which the refrigerator 100 is laid down for storage in the container 1, the movement of the compressor 20 is greater compared to the standing state in which the refrigerator 100 is standing, Because of this, there are problems with noise and deformation.

To this end, in the present invention, by installing a spacer 40 in the machine room 15 to minimize the flow of the compressor 20 in the machine room 15, noise and deformation can be prevented.

The compressor 20 may be mounted on the bottom cover 31 inside the machine room 15.

Referring to FIG. 2, the machine room 15 may be provided at the lower rear end of the refrigerator.

In the present invention, the compressor 20 may be a linear compressor 20. Since the linear compressor 20 is a known technology, a detailed description of the linear compressor 20 will be omitted and will be briefly described later, focusing on the components included in the drawings.

Additionally, the machine room 15 may be formed by a front cover and a rear cover 30 that form the front and rear sides of the machine room 15 . The spacer 40 may be installed on the rear cover 30 of the machine room 15.

The rear cover 30 of the machine room 15 is at the rear of the refrigerator 100 when it is in a standing state, but when it is in a laydown state, it is the bottom surface that is contacted by the sagging of the compressor 20, so the spacer 40 is used to cover the compressor 20. ) must be installed on the rear cover 30 of the machine room 15 to support the compressor 20 when it sags.

Meanwhile, the compressor 20 may be provided with a bracket 20b that couples the compressor 20 to the inner bottom cover 31 of the machine room 15.

The compressor 20 is coupled to the bracket 20b, and the bracket 20b is fixedly coupled to the inner bottom cover 31 of the machine room 15. The bracket 20b may be coupled to the bottom cover 31 by a coupling member 31a, which will be described later.

The bracket 20b supports the compressor 20 at a predetermined distance from the rear wall inside the machine room 15 when the refrigerator 100 is in a standing state.

Additionally, the bracket 20b supports the compressor 20 in contact with the rear cover 30 forming the inner rear wall of the machine room 15 when the refrigerator 100 is in a laydown state.

That is, in the laydown state of the refrigerator 100, the compressor 20 sags by a predetermined distance due to its own weight and comes into contact with the rear wall inside the machine room 15.

For example, the compressor 20 moves in the front-to-back direction of the refrigerator 100 by up to 15 mm when the refrigerator 100 is in a laydown state.

In the present invention, the forward direction of the refrigerator 100 is the direction toward the front where the door is placed and is upward with respect to FIG. 3, and the rear direction is the direction toward the side opposite the door where the door is not placed and is shown in FIG. 3 The direction is downward based on the standard.

If there is no spacer 40 on the inner rear wall of the machine room 15, where the compressor 20 is in contact with the machine room 15, it may flow about 22 to 23 mm forward and 26.7 mm to 31.1 mm backward. Additionally, wear of the discharge valve of the compressor 20 may occur.

As described above, the compressor 20 can be fixedly coupled to the bottom cover 31 inside the machine room 15 by the bracket 20b, and in the laydown state, the compressor 20 is attached to the rear cover of the machine room 15 ( 30) can be contacted.

FIG. 5A is a plan view showing the rear cover 30 of the machine room 15, FIG. 5B is a perspective view showing one side of the rear cover 30 with another example of a spacer 40 installed, and FIG. 5C is a deformation prevention portion. This is a perspective view showing the other side of the rear cover 30 on which (50) is installed.

5A to 5C, the spacer 40 installed on the rear cover 30 and the like will be described in more detail.

The rear cover 30 may be coupled to the cabinet 10 to form a rear wall inside the machine room 15. The rear cover 30 may include a heat dissipation guide 30a with heat dissipation holes 30b formed between the angles to discharge heat within the machine room 15.

A plurality of heat dissipation guides 30a may be formed on the rear cover 30 of the machine room 15 to be spaced apart at equal intervals. Likewise, a plurality of heat dissipation holes 30b may be formed between the plurality of heat dissipation guides 30a.

The heat dissipation hole 30b formed by the heat dissipation guide 30a may be formed with a plurality of perforations or a slit structure. As shown in FIG. 3 (although not clearly shown), the heat dissipation hole 30b has a plurality of slit structures. ) is formed.

As shown in FIG. 5A, the rear cover 30 of the machine room 15 may be provided with a spacer mounting portion 30c to which a spacer 40 is coupled between a plurality of heat dissipation guides 30a.

In addition, the spacer mounting portion 30c is formed at a position on the rear cover 30 of the machine room 15 that is contacted when sagging occurs by a predetermined distance due to the self-weight of the compressor 20 in the laydown state of the refrigerator 100. It has to be.

The spacer 40 is coupled to the spacer mounting portion 30c so that the compressor 20 is contacted and supported in the laydown state of the refrigerator 100.

In the laydown state of the refrigerator 100 by the spacer 40, the compressor 20 can be supported in a state spaced apart from the rear cover 30 of the machine room 15.

The spacer 40 may be made of a rubber material, for example, PU Foam (Polyurethane Foam) or EPDM (Ethylene Propylene Diene Monomer).

The spacer 40 may have dimensions of Width 45 * Height 40 * Thickness 15. The spacer 40 may be provided with a chamfer at each corner.

It is desirable that the spacer 40 be large in order to contact the compressor 20 or to prevent impact, but since there is a heat dissipation guide 30a with a heat dissipation hole 30b near the spacer mounting portion 30c, performance is hindered. It is desirable that it is manufactured so that it is not too large to prevent this.

Additionally, the spacer 40 may be cut using scissors or a cutting device. The spacer 40 may be cut and coupled to the spacer mounting portion 30c using double-sided tape or adhesive.

As a result of the experiment, when the spacer 40 is not mounted on the rear cover 30 of the machine room 15, the compressor 20 moves 14 mm in the sagging direction. Additionally, if the spacer 40 is not installed, deformation may occur in the rear cover 30 of the machine room 15.

On the other hand, when the spacer 40 is mounted on the spacer mounting portion 30c of the rear cover 30 of the machine room 15, the compressor 20 moves 10.3 mm in the sagging direction.

Compared to the case where the spacer 40 is not installed, when the spacer 40 is installed, when the compressor 20 sags due to its own weight in the laydown state of the refrigerator 100, it is supported by the spacer 40. This is because the structure is partially cushioned.

FIG. 4C shows an example in which the compressor 20 is partially rotated and sagging by a predetermined angle θ due to its own weight in the laydown state.

In addition, FIG. 4D shows an example in which the compressor 20, in a laydown state, is sagged by a predetermined distance d due to its own weight and comes into contact with the spacer 40. For example, d may be 15 mm.

To compare the cases with and without the spacer 40 installed, model analysis (FE. Model) was applied, and the boundary conditions constrained the fastening portions of the rear cover 30 and the bottom cover 31, respectively, The compressor 20 was dropped at 2500 mm/s, and the maximum stress that the rear cover 30 could withstand was compared.

As a result of the experiment, when the spacer 40 is not installed, the maximum stress that the rear cover 30 can withstand is 233 Mpa, but when the spacer 40 is installed, the maximum stress applied to the rear cover 30 is 233 Mpa. It increased to 274 Mpa.

In this way, in the refrigerator 100 of the present invention, the maximum stress that the rear cover 30 can withstand in a laydown state is further increased due to the structure in which the spacer 40 is mounted, thereby enhancing durability.

The refrigerator 100 of the present invention may further include a deformation prevention portion 50 installed on the opposite side of the spacer mounting portion 30c of the rear cover 30 to prevent deformation of the rear cover 30.

That is, it can be understood that the spacer 40 is installed on the rear cover 30 inside the machine room 15, while the deformation prevention part 50 is installed on the rear cover 30 outside the machine room 15.

For this purpose, the outer rear cover 30 of the machine room 15 may be provided with a deformation-prevention mounting portion 30d.

The anti-deformation mounting portion 30d may be coupled between a plurality of heat dissipation guides 30a on the rear cover 30 outside the machine room 15.

The deformation-resistant mounting portion 30d may be provided on the opposite side of the spacer mounting portion 30c, with the rear cover 30 interposed therebetween.

The deformation prevention portion 50 may be made of a rubber material, for example, PU Foam (Polyurethane Foam) or EPDM (Ethylene Propylene Diene Monomer).

Additionally, the deformation prevention portion 50 may be cut using scissors or a cutting device. The deformation prevention portion 50 may be cut and coupled to the deformation prevention mounting portion 30d using double-sided tape or adhesive.

In order to compare the cases with and without the deformation prevention part 50 installed, model analysis (FE. Model) was applied, and the boundary conditions were the fastening parts of the rear cover 30 and the bottom cover 31, respectively. After being restrained, the compressor 20 was dropped at 2500 mm/s, and the maximum plastic strain rate that the bottom cover 31 could withstand was compared.

As a result of the experiment, when the deformation prevention part 50 was not installed, the maximum plastic strain applied to the bottom cover 31 was 1.3%, but when the deformation prevention part 50 was installed, the maximum plastic strain applied to the bottom cover 31 was 1.3%. It was confirmed that the maximum plastic strain rate decreased to 0.5%.

In this way, the refrigerator 100 of the present invention has a structure in which the spacer 40 and the deformation prevention portion 50 are mounted, so that the maximum plasticity applied to the bottom cover 31 in the laydown state of the refrigerator 100 The strain rate is further reduced, and durability is strengthened.

In the present invention, the compressor 20 is coupled to the bottom cover 31 of the machine room 15.

For this purpose, the compressor 20 may be provided with a bracket 20b to be coupled to the bottom cover 31 of the machine room 15.

Additionally, the bottom of the machine room 15 may be made of a bottom cover 31, and a coupling member 31a to which the bracket 20b of the compressor 20 is coupled is inserted and coupled to the bottom cover 31.

The bottom cover 31 may be formed as a single member, such as the rear cover 30 described above, or may be formed as other members and combined with each other.

The coupling member 31a may be coupled to the bottom cover 31 of the machine room 15 by a coupling method such as a bolt or pin. However, it is not necessarily limited to bolts or pins, and can be coupled by various coupling methods.

Figure 6c shows an example in which four pins are coupled to the bottom cover 31 by welding.

Vibration of the compressor 20 can be prevented by the coupling member 31a.

The coupling member 31a may be, for example, a seat rubber, thereby preventing vibration of the compressor 20.

The bracket 20b is inserted and coupled to the coupling member 31a. For this purpose, the coupling member 31a may be provided with a coupling groove. Additionally, the bracket 20b may include a coupling hole 20b-1.

Of course, the coupling member 31a must be coupled to have sufficient rigidity to support the compressor 20 when the refrigerator 100 is laid down.

As described above, when the refrigerator 100 is laid down, the compressor 20 hangs down while being fixed to the coupling member 31a by its own weight, and the spacer 40 installed on the rear cover 30 is supported by contact.

Meanwhile, the compressor 20 may be configured to include a shell 20a, a compression unit 24, an electric motor, and a discharge member, as shown in FIGS. 4A and 4C.

The compressor 20 has a general configuration, but in the present invention, it will be briefly described with reference to FIGS. 4A and 4C.

The shell 20a forms the exterior of the compressor 20, and has an intake port 20c that sucks the refrigerant into the inside and a bracket 20b that allows the compressor 20 to be coupled to the bottom cover 31 of the machine room 15. ) can be provided.

Although not shown in detail in the drawings, the compression unit 24 may include a cylinder 26a having a compression space and a piston 26b that can move in the compression space and compress the refrigerant.

The electric motor may include an outer stator fixedly coupled to the outside of the cylinder 26a, an inner stator and a magnet spaced apart inside the outer stator.

The magnet may be a permanent magnet that reciprocates in a straight line due to mutual electromagnetic force between the outer stator and the inner stator, and is connected to the piston 26b to enable the piston 26b to move in a straight line.

A stator cover 27 may be coupled to the outer stator with a bolt.

In addition, a spring 25 is coupled to the stator cover 27 to elastically support the electric motor and the compression unit 24 connected thereto.

In addition, in FIG. 4A, a compression support portion 22 provided with a support spring 22a to support the compression portion 24 is shown, and stoppers disposed above and below the inner circumference of the shell 20a are also shown in the drawing.

Although not shown in FIG. 4A, etc., a discharge member may be installed on the front of the cylinder 26a facing the compression space to discharge the compressed refrigerant from the compression portion 24 into the inside of the shell 20a and discharge it to the outside. You can.

Hereinafter, the internal configuration of a general cabinet 10 related to the refrigerator 100 of the present invention will be described.

In the present invention, the food storage compartment provided inside the cabinet 10 may be implemented to include a freezer compartment and a refrigerator compartment, or the entire food storage compartment may be formed only by the freezer compartment. If the entire pantry is formed only by the freezer, the compartments can be divided into different temperatures.

FIG. 6A is a conceptual diagram showing an example in which the compressor 20 is installed in the machine room 15 to measure the displacement of the compressor 20, and FIG. 6B is an exploded perspective view showing an example in which the compressor 20 is installed in the machine room 15. , FIG. 6C is a perspective view showing an example in which the compressor 20 is installed in the machine room 15, and FIG. 6D is a table showing the displacement of the compressor 20 in the x, y, and z axis directions in FIG. 6A.

Hereinafter, with reference to FIGS. 6A and 6D, the results of measuring the displacement of the compressor 20 within the machine room 15 will be described.

In FIG. 6A , as described above, the compressor 20 is coupled to the bottom cover 31 in the drawing within the machine room 15, and in the drawing, the upper portion (direction of the Z-axis arrow) is above the refrigerator 100. The downward direction is the downward direction of the refrigerator 100.

Additionally, the x, y, and z axes directions are shown in FIG. 6A, where the x-axis direction is (+) on the right and (-) on the left. In the Y-axis direction, the direction opposite to the direction in which the arrow penetrates the drawing (the direction in which it sags due to its own weight) is (+), and the opposite direction is (-). In the drawing, the Z-axis direction is (+) in the upward direction (direction toward the top of the refrigerator 100), and (-) is in the downward direction (direction toward the bottom of the refrigerator 100).

Figure 6c shows the results of an experiment performed on three models of refrigerators. It can be seen that there is a lot of flow in the laydown state of the refrigerator 100 in the (+) and (-) directions of the Y direction.

Hereinafter, the process in which the compressor 20 is supported by the spacer 40 in the refrigerator 100 of the present invention in a laydown state will be described.

In order to load the refrigerator 100 into the additional loading space c of the container 1, when the refrigerator 100 is laid down, the rear cover 30 of the machine room 15 forms the bottom, and the compressor ( The bottom cover 31 to which the bracket 20b of 20 is coupled forms a side surface, so that the compressor 20 sags downward due to its own weight.

At this time, the compressor 20 does not collide with the rear cover 30 and is stably supported by the spacer 40 due to the spacer 40 installed in the spacer mounting portion 30c of the rear cover 30.

In addition, even if an impact is applied to the laid-down refrigerator 100 by an external force while transporting the container 1, the flow of the compressor 20 can be minimized by the spacer 40.

Meanwhile, due to the deformation prevention part 50 installed on the deformation prevention mounting part 30d on the opposite side of the rear cover 30, the bottom cover 31 is caused by the sagging of the compressor 20 in the laydown state of the refrigerator 100. The maximum plastic strain applied to is further reduced, thereby enhancing durability.

The refrigerator 100 described above is not limited to the configuration and method of the embodiments described above, and the embodiments may be configured by selectively combining all or part of each embodiment so that various modifications can be made.

It is obvious to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential features of the present invention. Accordingly, the above detailed description should not be construed as restrictive in all respects and should be considered illustrative. The scope of the present invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the present invention are included in the scope of the present invention.
