Description

storage

The present invention relates to a storage.

The storage unit may include a storage room for storing items. The storage unit may include, for example, a refrigerator.

A refrigerator is a device that cools or stores refrigerated items such as food, medicine, and cosmetics (hereinafter referred to as food for convenience) at low temperatures to prevent spoilage or deterioration. A refrigerator includes a storage room where food is stored and a refrigeration cycle component that cools the storage room.

Refrigeration cycle components may include a compressor, condenser, expansion device, and evaporator through which refrigerant is circulated.

A refrigerator according to the related art may include an outer case and an inner case positioned inside the outer case and having an open front. Such a refrigerator may have a cold air discharge duct arranged inside the inner case and dividing the inside of the inner case into a storage room and a heat exchange room. For example, a storage room may be formed in front of the cold air discharge duct, and a heat exchange room may be formed in the rear. An evaporator and an evaporation fan may be arranged in the heat exchange room.

The refrigerator may have a separate machine room formed outside the inner case, a compressor, a condenser, and a condensing fan may be placed in the machine room, and the compressor in the machine room may be connected to the evaporator in the heat exchange room by a refrigerant pipe.

The above storage room may be provided with a drawer that is provided to be withdrawable. The drawer may be provided in multiple numbers in an up-down direction.

According to the refrigerator according to the above conventional technology, the following problems arise.

First, since the compressor, which is placed in the machine room, and the evaporator, which is placed inside the inner case, are placed in separate spaces and connected by refrigerant piping, there is an inconvenience in that when repairs are required for refrigeration cycle components, food stored in the refrigerator must be taken out to check for malfunctions and perform repairs.

Second, the evaporator is integrally formed inside the refrigerator body and must be fixed to the refrigerator body by welding, etc., making the refrigerator cumbersome to manufacture. In addition, there is a problem that the internal temperature rises when the evaporator is defrosted due to heat exchange with the storage room.

Third, since the heat exchange room is located at the rear of the storage room, the front-to-rear width of the rear wall of the refrigerator body increases by the size of the heat exchange room, and accordingly, there is a problem in that the volume of the storage room is reduced by that amount.

In order to solve these problems, a storage facility equipped with a heat exchange device that is configured as an integrated heat exchange room and a machine room has been recently introduced. When the heat exchange device is combined with the storage body, if the heat exchange room is not in close contact with the storage body, the problem of the insulation performance of the storage facility deteriorating may occur.

The fastening member may pass through the fastening hole (452) and be fastened to the inner surface of the storage body (10).

The hinge holder (450) may include a first part (460) extending in the direction in which the heat exchanger case (200) is introduced. The first part (460) may have a first length (a) in the direction in which the heat exchanger case (200) is introduced.

The above hinge holder (450) may include a second part (470) that is bent from the first part (460) and extends at an angle with respect to the direction in which the heat exchanger case (200) is introduced.

The second part (470) may have a second length (b) extending in a direction inclined with respect to the direction in which the heat exchanger case (200) is introduced. The second length (b) may be formed to be greater than the first length (a).

A guide groove (475) can be defined by the first and second parts (460, 470) above. The guide groove (475) can provide a space in which the hinge protrusion (420) of the hinge device (400) moves.

A part of the inner surface of the above guide groove (475) may be formed by the inner surface of the first part (460), and another part of the inner surface of the above guide groove (475) may be formed by the inner surface of the second part (470).

The above guide home (475) may include an inclined surface (473) that allows the heat exchanger case (200) to move in a direction approaching the partition wall (50) when the heat exchanger case (200) is introduced. The inclined surface (473) may extend so as to be inclined in a direction in which the heat exchanger case (200) approaches the partition wall (50).

The above first part (460) may include a first end (461) that forms a leading edge in the direction in which the heat exchanger case (200) approaches when the heat exchanger case (200) is introduced.

The second part (470) may include a second end (471) that forms a leading edge in the direction in which the heat exchanger case (200) approaches when the heat exchanger case (200) is introduced.

The second end (471) may be positioned closer to the open end of the device receiving space (18) than the first end (461).

In detail, the virtual second extension line (ℓ2) extending the second end (471) in the vertical direction, i.e., in the direction in which the heat exchanger case (200) is in close contact with the partition wall (50), can be positioned closer to the open end of the device receiving space (18) than the virtual first extension line (ℓ1) extending the first end (461) in the vertical direction.

Therefore, during the process of introducing the heat exchanger case (200), the hinge projection (420) can first approach the second end (471) and then approach the first end (461).

The above-mentioned inclined surface (473) can be formed to be inclined in a direction approaching the partition wall (50) from the second end (471).

The above hinge projection (420) moves along the inclined surface (473), and in this process, the heat exchanger case (200) can move in a direction closer to the contact surface (sealing surface) with the partition wall (50). For example, the first part of the heat exchanger case (200) can be lifted toward the partition wall (50).

The hinge projection (470) can move to the end of the guide groove (475) when moving along the inclined surface (473). For example, the hinge projection (470) can come into contact with the end of the guide groove (475).

Referring to FIG. 4 and FIG. 10 together, the lever device (500) according to the first embodiment of the present invention may include a lever (510) supported on the storage body (10). The lever (510) may be rotatably supported on a lever cover (520).

The above lever (510) can be accommodated in the recessed portion (522) of the lever cover (520) at the first position. The lever (510) can be rotated from the first position to the second position, and can be pulled out from the recessed portion (522) at the second position.

The above lever cover (520) can be fastened to the second part of the heat exchanger case (210).

The above lever (510) may include a lever body (511) forming a recessed portion (513). The recessed portion (513) may provide a space accessible to an operator for operating the lever (510).

When the above lever (510) is fastened to the lever holder (550), the recessed portion (513) can be positioned to open toward the front of the refrigerator. Accordingly, access by the operator is easy.

For convenience of explanation, the recessed portion (513) of the lever (510) may be called the “first recessed portion” and the recessed portion (522) of the lever cover (520) may be called the “second recessed portion”.

The above lever (510) may include a fastening hole (514) that is fastened to the lever holder (550). The fastening hole (514) is formed at an end of the recessed portion (513), and a predetermined fastening member may be fastened to the lever holder (550) by passing through the fastening hole (514).

The above lever (510) may include a lever protrusion (515) that provides a center of rotation of the lever (510). The lever protrusion (515) protrudes from the lever body (511) and may be inserted into a protrusion groove (525, see FIG. 16a/16b) of the lever cover (520).

The above lever protrusions (515) are provided in pairs and can be provided on both sides of the lever body (511), for example, on the top and bottom of the lever body (511).

One side of the lever body (511) may form a support surface (512) supported by the lever holder (550). For example, the support surface (512) may form the bottom surface of the lever body (511).

Referring to Fig. 11, a lever holder (550) according to the first embodiment of the present invention may be provided on the inner surface of the storage body (10). For example, the lever holder (550) may be provided at a position adjacent to the front end of the device receiving space (18).

The above lever holder (550) may include a first part (560) extending in the direction in which the heat exchanger case (200) is introduced, and a second part (570) extending from the first part (560) in the direction in which the heat exchanger case (200) is brought into close contact with the partition wall (50).

By means of the first and second parts (560, 570) above, the lever holder (550) can have an overall bent “L” shape.

One side of the first part (560) may include a support part (562). For example, the support part (562) may be formed on the upper surface of the first part (560). The support surface (512) of the lever (510) may be supported by the support part (562).

The first part (560) may further include an inclined part (563) formed at the tip of the support part (562). The inclined part (563) is a part that reaches before the support part (562) when the lever (510) rotates to the second position, and may perform a function of preventing the lever (510) from interfering with the lever holder (550).

That is, the inclined part (563) is a cutting part and can extend inclinedly from the support part (562) toward the tip of the first part (560).

The above lever holder (550) may include a plurality of fastening holes (552, 554).

The above-described plurality of fastening holes (552, 554) may include a first fastening hole (552) penetrating the side of the lever holder (550). A predetermined fastening member may pass through the first fastening hole (552), and the fastening member may be fastened to the inner surface of the storage body (10).

The above-described plurality of fastening holes (552, 554) are formed in the second part (570) and may include a second fastening hole (554) to which a predetermined fastening member is fastened. The fastening member may be fastened to the second fastening hole (554) by passing through the fastening hole (514) when the lever (510) is in the rotated second position.

The above lever (510) is rotated to the second position and supported on the support part (562), and the fastening member can pass through the fastening hole (514) and be fastened to the second fastening hole (554) of the lever holder (550).

When the lever (510) and the lever holder (550) are connected, the connecting member is exposed to the front of the refrigerator through the recessed portion (513) of the lever (510), so that the worker can easily access the connecting member.

FIGS. 12 to 14 are drawings sequentially showing a heat exchanger case according to the first embodiment of the present invention being mounted on a storage body.

The above heat exchange device (100) can be introduced rearwardly through the open front portion of the device receiving space (18). The heat exchange case (200) forming the first heat exchange unit and the machine room forming the second heat exchange unit, i.e., the compressor (121) and the second heat exchanger (123), can be introduced while mounted on the base (110).

When the heat exchanger (100) is in the introduced position, the second heat exchanger (123) may be located at the rear of the device receiving space (18). In addition, the heat exchange case (200) may be in a position where it contacts the hinge holder (450). In detail, the hinge protrusion (420) may be in a state where it contacts the inclined surface (473) of the hinge holder (450).

The upper part of the heat exchanger case (200) may be spaced apart from the partition wall (50). The sealing member (240) provided on the upper surface of the heat exchanger case (200) may be spaced apart from the partition wall (50) by a first distance (S1).

Thereafter, the heat exchange case (200) can be introduced a little further, and during this process, the hinge protrusion (420) can move upward along the inclined surface (473). As shown in Fig. 13, the hinge protrusion (420) can move until it contacts the end of the guide groove (475) of the hinge holder (450).

Since the hinge protrusion (420) is located at the rear of the heat exchanger case (200), the rear part of the heat exchanger case (200) is lifted by moving the hinge protrusion (420) upward.

For example, as illustrated in FIG. 13, the rear portion of the heat exchanger case (200) can rise by a first height (H1) from the point where the hinge protrusion (420) contacts the hinge holder (450).

At this time, the sealing member (240) may be adjacent to the partition wall (50). For example, the second distance (S2) between the sealing member (240) and the partition wall (50) may be smaller than the first distance (S1). However, since the sealing member (240) is spaced apart from the partition wall (50), damage due to friction with the partition wall (50) can be prevented.

In the state of Fig. 13, the front part of the heat exchanger case (200) can be lifted. Accordingly, the heat exchanger case (200) can be in a state where the front part and the rear part are spaced upward from the tray (130) while maintaining balance.

The above heat exchanger case (200) can be spaced apart from the tray (130) by a third distance (S3).

During the process in which the heat exchanger case (200) is introduced into the device receiving space (18) and raised upward, the lever (510) is received in the recessed portion (522) of the lever cover (520), i.e., is not protruded to the side of the heat exchanger case (200), so that it may not interfere with the lever holder (550).

As shown in Fig. 14, when the heat exchanger case (200) is lifted upward from the tray (130), the lower surface of the lever (510), i.e., the support surface (512), may be at a position where it can be supported by the support part (562) of the lever holder (550), for example, at a position slightly higher than the support part (562).

In the state of Fig. 14, the sealing member (240) is in a state of being in close contact with the partition wall (50). As described above, in the state of Fig. 13, the sealing member (240) is in a state of being spaced apart from the partition wall (50), and when the heat exchanger case (200) is lifted upward, the sealing member (240) can be in close contact with the partition wall (50).

The above sealing member (240) can be positioned so as to be compressed by a predetermined compression height (C1). The compression height (C1) can be understood as the compression amount of the sealing member (240).

FIG. 15 is a drawing showing a state in which a heat exchanger case according to a first embodiment of the present invention is in close contact with a storage body, and a lever device is fastened to a lever holder, FIGS. 16a and 16b are drawings showing in sequence a state in which a lever according to the first embodiment of the present invention is fastened to a lever holder, and FIG. 17 is a cross-sectional view taken along line 17-17 of FIG. 15.

FIG. 15 shows a state in which a lever (510) according to the first embodiment of the present invention is supported by a support part (562) of the lever holder (550) while rotating with respect to a lever cover (520).

Fig. 16a shows the relative positions of the lever (510) and the lever holder (550) in the state of Fig. 14. The lever (510) is accommodated in the recessed portion (522) of the lever cover (520), and the lever protrusion (515) of the lever (510) can be accommodated in the protrusion groove (525) of the lever cover (520).

The above lever (510) rotates around the lever projection (515) and can protrude laterally from the heat exchanger case (200). The support surface (512) of the lever (510) can be located on the upper side of the support part (562) of the lever holder (550).

The fastening hole (514) of the lever (510) can be aligned with the second fastening hole (554) of the lever holder (550). The fastening member (580, see FIG. 17) can be fastened to the lever holder (550) by passing through the fastening hole (514) and the second fastening hole (554) of the lever (510).

Since the front of the above lever (510) is open by the recessed portion (513), the worker can easily access the fastening hole (514) of the lever (510) and fasten the fastening member (580).

Referring to FIG. 17, a first part of the heat exchanger case (200) is supported on the storage body (10) by a hinge device (400) and a hinge holder (450), and a second part of the heat exchanger case (200) can be fastened to the storage body (10) by a lever (510) and a lever holder (550).

The above hinge device (400) may include a hinge bar (410) extending in the forward and backward directions. A plurality of reinforcing ribs (416) may be provided inside the hinge bar (410) to reinforce the strength of the hinge device (400).

In this way, the front and rear parts of the heat exchanger case (200) are stably supported by the hinge device and lever device (500), and the heat exchanger case (200) can be closely attached to the partition wall (50) through the sealing member (240). Accordingly, the insulation performance inside the heat exchanger case (200) can be improved.

Hereinafter, the second to fourth embodiments of the present invention will be described. These embodiments differ from the first embodiment only in some configurations, so the differences will be mainly described, and the drawing references and descriptions of the first embodiment will be used for the same parts as the first embodiment.

FIG. 18 is a drawing showing the configuration of a heat exchanger case according to a second embodiment of the present invention, FIG. 19 is a drawing showing the configuration of a hinge holder according to a second embodiment of the present invention, FIG. 20 is a drawing showing the heat exchanger case according to the second embodiment of the present invention in an introduced state, and FIG. 21 is a drawing showing the heat exchanger case according to the second embodiment of the present invention in an introduced state and rotating about a hinge device.

Referring to FIGS. 18 to 21, the heat exchanger case (200a) according to the second embodiment of the present invention may include an inclined bottom surface.

In detail, the bottom surface of the heat exchanger case (200a) may include a first bottom surface portion (217a) extending parallel to the base (110) and a second bottom surface portion (217b) extending at an angle (θ1) from the first bottom surface portion (217a) toward the partition wall (50).

For example, the second bottom surface (217b) may extend from the first bottom surface (217a) in a direction in which the heat exchanger case (200a) is introduced into the device receiving space (18).

By this configuration, the heat exchanger case (200a) can have a shape in which the rear part is lifted upward.

The configuration of the above heat exchanger case (200a) is similar to the heat exchanger case (200) described in the first embodiment, except for the first and second bottom portions (217a, 217b).

The configuration in which a lever (510) and a lever cover (520) are provided at the front of the heat exchanger case (200a) and the configuration in which a hinge device (400) is provided at the rear are the same as those described in the first embodiment, so the description of the first embodiment is used.

The above heat exchanger case (200a) can be supported on a hinge holder (450a). During the process of introducing the heat exchanger case (200a), the hinge device (400) can come into contact with the hinge holder (450a) and move along the guide groove (475a).

The hinge holder (450a) may include a first part (460a) extending in the direction in which the heat exchanger case (200a) is introduced, a second part (471a) bent from the first part (460a), and a third part (472a) extending from the second part (471a) in the opposite direction to the direction in which the heat exchanger case (200a) is introduced.

The above hinge holder (450a) is defined by the first to third parts (460a, 471a, 472a) and may include a guide groove (475a) with which the hinge projection (420) of the hinge device (400) comes into contact.

The above guide groove (475a) may be configured as a horizontal groove to guide the horizontal movement of the hinge projection (420) as a whole.

The inner surface of the third part (472a) may include an inclined surface (473a) that is formed to be inclined so that the hinge projection (420) can be easily inserted into the inside of the guide groove (475a). The inclined surface (473a) may be formed to be inclined so that the distance between the first part (460a) and the third part (472a) increases toward the front.

The inner surface of the third part (472a) may include a flat surface (474a) extending flatly rearwardly from the inclined surface (473a). The direction in which the flat surface (474a) extends may be parallel to the partition wall (50).

Referring to Fig. 20, when the heat exchanger case (200a) is introduced into the device receiving space (18), the hinge projection (420) of the hinge device (400) can come into contact with the hinge holder (450a). The hinge projection (420) can be inserted into the guide groove (475a) and continue to move.

The above hinge projection (420) moves until it contacts the end of the guide groove (475a), and when it contacts the guide groove (475a), further movement may be restricted.

In this state, the sealing member (240) provided on the upper end of the heat exchanger case (200a) is spaced apart from the partition wall (50) by a predetermined distance (S4). That is, during the process of introducing the heat exchanger case (200a), the sealing member (240) does not interfere with surrounding structures such as the partition wall (50) and the hinge holder (450a), so that damage can be prevented.

With the hinge projection (420) supported on the hinge holder (450a), the front portion of the heat exchanger case (200a) can be lifted upward. Accordingly, the heat exchanger case (200a) can be in a state where the front portion and the rear portion are spaced upward from the tray (130) while maintaining balance.

In the state of Fig. 21, the sealing member (240) is in a state of being in close contact with the partition wall (50). As described above, in the state of Fig. 20, the sealing member (240) is in a state of being spaced apart from the partition wall (50), and when the heat exchanger case (200) is lifted upward, the sealing member (240) can be in close contact with the partition wall (50).

The above sealing member (240) can be positioned so as to be compressed by a predetermined compression height (C2). The compression height (C2) can be understood as a compression amount of the sealing member (240).

Since the configuration of the above lever (510) and lever cover (520), the configuration of the lever holder (550), and the configuration of the lever (510) being fastened to the lever holder (550) are the same as those of the first embodiment, the description of the first embodiment is used.

FIG. 22 is a drawing showing the configuration of a hinge holder according to a third embodiment of the present invention, and FIGS. 23a and 23b are drawings showing a hinge protrusion moving while being guided in a hinge holder according to the third embodiment of the present invention.

Referring to FIGS. 22 to 23b, a hinge holder (450b) according to a third embodiment of the present invention may include a first part (460b) extending in the direction in which the heat exchanger case (200) is introduced.

The above hinge holder (450b) may include a second part (470b) that is bent from the first part (460b) and extends at an angle with respect to the direction in which the heat exchanger case (200) is introduced.

A guide groove (475b) can be defined by the first and second parts (460b, 470b) above. The guide groove (475b) can provide a space in which the hinge protrusion (420) of the hinge device (400) moves.

A part of the inner surface of the above guide groove (475b) may be formed by the inner surface of the first part (460b), and another part of the inner surface of the above guide groove (475b) may be formed by the inner surface of the second part (470b).

The above guide home (475b) may include an inclined surface (474b) that allows the heat exchanger case (200) to move in a direction approaching the partition wall (50) when the heat exchanger case (200) is introduced. The inclined surface (474b) may extend so as to be inclined in a direction in which the heat exchanger case (200) approaches the partition wall (50).

The above guide groove (475b) may include a flat surface (473b) that extends flatly from the inclined surface (474b) toward the tip of the hinge holder (450b). The hinge projection (420) of the hinge device (400) may first contact the flat surface (473b) and then move along the inclined surface (474b).

The hinge projection (420) can be easily supported after being inserted into the inside of the guide groove (475b) by the flat surface (473b), and the hinge device (400) can easily move in a direction closer to the partition wall (50) by the inclined surface (474b).

As described in the first embodiment, the hinge projection (420) can move until it interferes with the end of the guide groove (475b).

FIG. 24 is a drawing showing the configuration of a hinge holder according to a fourth embodiment of the present invention, and FIGS. 25a and 25b are drawings showing a hinge protrusion moving while being guided in a hinge holder according to the fourth embodiment of the present invention.

Referring to FIGS. 24 to 25b, the hinge holder (450c) according to the fourth embodiment of the present invention can extend obliquely with respect to the direction in which the heat exchanger case (200) is introduced.

The above hinge holder (450c) may include an inclined surface (473c) that guides the hinge projection (420) to move in a direction in which it comes into contact with and approaches the partition wall (50). The inclined surface (473c) may extend rearward from the tip of the hinge holder (450c).

The above hinge holder (450c) is formed at an end of the inclined surface (473c) and may include a protrusion (475c) protruding from the inclined surface (473c).

The above hinge holder (450c) may include a mounting surface (474c) that extends in a bent or rounded manner from the jaw (475c). The mounting surface (474c) may be understood as a portion where the hinge projection (420) is mounted when the introduction of the heat exchanger case (200) is completed.

The above jaw (475c) can form a boundary between the inclined surface (473c) and the seating surface (474c).

The above-mentioned jaw (475c) functions as a catch to prevent the hinge projection (420) from flowing in the direction toward the inclined surface (473c) when it is seated on the seating surface (474c), so that the heat exchanger case (200) can be stably supported on the storage body (10).

As can be seen from the embodiments described above, the hinge device and the hinge holder can be called an “inclining mechanism” in that they guide the heat exchanger case to perform an inclined movement toward the partition wall.

The bottom configuration of the heat exchanger case (200a) described in the second embodiment is a configuration for arranging the heat exchanger case (200a) so as to be inclined upward, and can be called an “inclined mechanism.”

In addition, the above lever device and lever holder can be called a “fastening mechanism” in that they fasten the heat exchanger case to the storage body.

The present invention relates to a storage, wherein first and second storage rooms are fluidly connected so that a fluid exchanged in a first heat exchanger can be easily supplied to the first storage room, and a fluid inside the first storage room can be easily returned to the second storage room. Therefore, the industrial applicability is remarkable.
