Description

Article storage system for vestibule

Technical Field

The present invention relates to a vestibule article storage system.

Background

Recently, express services for delivering items to a prescribed location are very active. If the item is fresh food, the food is stored in a refrigerator or incubator provided in a delivery vehicle and then delivered in order to prevent the food from being damaged or cooled.

Typically, the food is served after being wrapped with a packaging material that can be cold or warm. Since the packaging material is made of environmental pollutants such as polystyrene foam, the call for the reduction of the use of the material has recently been increasing.

On the other hand, if the user is at home, the dispatcher can directly transfer the food to the user, but if the user is not at home or the dispatch time is too late or too early, it is difficult for the dispatcher to directly transfer the food to the user.

Therefore, even if the dispatcher and the user do not meet directly, the user can receive the food, and the food is not damaged or cooled until the user finally passes the food.

For this reason, recently, there has been a product in which a refrigerator is installed at an entrance (vestibule) of a prescribed place, a dispatcher can store food in the refrigerator to keep it fresh, and a user can take out the food from the refrigerator at a convenient time.

The following patent documents disclose a vestibule refrigerator provided in a vestibule door or embedded in a wall for partitioning a vestibule corridor.

Patent literature: korean patent No. 20-0357547 (2004, 07, 19 days)

The wall-type vestibule-embedded refrigerator disclosed in the above patent document has the following problems.

First, a structure in which a normal cooling device is provided on the bottom surface side of a storage chamber is described, but a specific cooling device type or design structure is not mentioned.

Second, the structure of discharging the hot air generated in the cooling device to the outdoor corridor is described, but this structure causes the hot air to be directly blown to the outside person passing through the corridor, resulting in discomfort to the outside person passing through the corridor.

Third, in summer, hot air generated in the cooling device is discharged to the outdoor corridor, which may become a cause of increasing the corridor air temperature.

Fourth, when hot air generated in the cooling device is discharged to the indoor vestibule, if the height of the discharge opening is lower than the height of the user, the hot air directly contacts the user, thus causing discomfort to the user.

The second storage box 6 may serve as a simple function of storing the items to be delivered by being kept at the normal temperature, or may be kept at a temperature different from the temperature in the vestibule refrigerator 10 and lower than the normal temperature.

Of course, the first storage 5 may be kept at a refrigerating or freezing temperature, and the second storage 6 may be used as a room for keeping a normal temperature, which only plays a role of storing the express items.

On the other hand, at the side wall of the indoor vestibule behind the vestibule refrigerator 10, one or more third storage boxes 8 may be provided. The third storage box 8 may be used as a space for storing shoes or umbrellas or laundry.

The first storage box 5 may include: a first housing 5c having a first storage chamber formed therein; a first outer door 5a that selectively opens and closes a first front opening portion formed in a front surface of the first housing 5 c; and a first inner door 5b that selectively opens and closes a first side opening portion formed on an indoor side of the first housing 5 c.

The third storage chamber may be partitioned into a plurality of storage spaces up and down by one or more partition plates (not shown).

On the other hand, a gap is formed between the vestibule refrigerator 10 and the third storage box 8, and the gap can function as an indoor air flow path for cooling a hot side radiator (described later) attached to the back surface of the vestibule refrigerator 10.

The rear surfaces of the first storage box 5, the vestibule refrigerator 10, and the second storage box 6 and the gap formed between the side surfaces of the third storage box 8 opposite to the rear surfaces are shielded by a baffle 40.

The structure and function of the baffle 40 will be described in detail with reference to the accompanying drawings.

Fig. 3 is a front perspective view of a vestibule refrigerator according to an embodiment of the present invention, fig. 4 is a rear perspective view of the vestibule refrigerator, fig. 5 is an exploded perspective view of the vestibule refrigerator, fig. 6 is a cross-sectional perspective view of the vestibule refrigerator cut along line 6-6 of fig. 3, fig. 7 is a side sectional view of the vestibule refrigerator cut along line 7-7 of fig. 3, and fig. 8 is a longitudinal sectional view of the vestibule refrigerator cut along line 8-8 of fig. 3.

Referring to fig. 3 to 8, the vestibule refrigerator 10 according to the embodiment of the present invention can be understood as an embedded wall type refrigerator having a front portion penetrating through the outer wall 1.

In detail, the vestibule refrigerator 10 may include: a case 11, a part of which is embedded in the outer wall 1; an outer door 12 for opening and closing an outer opening 114 formed in a front end portion of the case 11; an inner door 13 for opening and closing an inner opening 115 formed in a side surface of the case 11; and one or more cool air supply modules 20 installed at the rear surface of the case 11.

Here, the outer opening 114 is formed on the front surface of the case 11, and thus may be defined as a front opening, and the inner opening 115 is formed on the side surface of the case 11, and thus may be defined as a side opening.

Alternatively, one of the outer opening 114 and the inner opening 115 may be defined as a first opening, and the other may be defined as a second opening. Also, either one of the outer door 12 and the inner door 13 may be defined as a first door, and the other one may be defined as a second door.

In addition, the meaning that the vestibule refrigerator 10 is installed at the outer wall for dividing the indoor and outdoor should be interpreted to include not only the case of being embedded in the wall for dividing the indoor and external hallways but also the case of being embedded in the wall for dividing the first space and the second space.

For example, the following situations may also be included: a wall is formed between the vestibule door and an intermediate door for separating the vestibule and the living room, and a vestibule refrigerator is embedded in the wall. In this case, when articles are put in from the vestibule, the articles may be taken out from the kitchen located on the opposite side of the vestibule.

Therefore, either one of the space where the outer door 12 is exposed and the space where the inner door 13 is exposed may be defined as a first space, and the other one may be defined as a second space. Either one of the first space and the second space may include either one of an indoor space or an outdoor space, and the other one of the first space and the second space may include an indoor space.

In another embodiment, the space where the door is opened to store the delivered items may be one of an indoor space and an outdoor space, and the space where the door is opened to take out the delivered items may be an indoor space.

In addition, the vestibule refrigerator 10 may further include: a heat radiation cover 15 covering the back surface of the cool air supply module 20; and an outside air guide 16 that guides the flow of the heat radiation air discharged through the heat radiation cover 15.

In the present embodiment, a pair of cold air supply modules 20 are arranged up and down, and a pair of heat dissipation covers 15 cover the respective cold air supply modules 20. The outside air guide 16 may be disposed between a pair of heat dissipation covers 15 disposed up and down, and may perform a function of guiding the flow of the heat dissipation air discharged from the lower heat dissipation cover 15.

The pair of cold air supply modules 20 may be defined to include an upper side first cold air supply module and a lower side second cold air supply module.

Here, a structure in which one cool air supply module 20 is disposed at the center of the rear surface of the case 11 is also within the scope of the present invention, and the outside air guide 16 may be omitted.

The heat dissipation cover 15 may be formed in a hexahedral shape with a front surface thereof opened, and the heat dissipation cover 15 may be fixed to the rear surface of the case 11 by a flange bent and extended from the front surface of the opening.

In addition, a plurality of ventilation holes are formed in the heat dissipation cover 15 on only the back surface, the left side surface, and the right side surface, in addition to the top surface and the bottom surface. According to this structure, the indoor air can flow into the heat dissipation cover 15 through the vent holes formed in the back surface of the heat dissipation cover 15, exchange heat, and then be discharged to the outside of the heat dissipation cover 15 through the vent holes formed in the left and right sides of the heat dissipation cover 15.

The vestibule refrigerator 10 may further include a guide plate 17 disposed at the rear side of the inside of the cabinet 11. The guide plate 17 is understood to be a partition member that divides the inner space of the case 11 into an evaporation chamber 102 that accommodates the cold air supply module 20 and a storage chamber 101 that stores the delivered articles.

The vestibule refrigerator 10 may further include a drain pan (drain pan) 14 and a drain hose 141 mounted on a lower end of a rear surface of the cabinet 11. The drain hose 141 penetrates the lower end of the rear surface of the case 11 from the bottom of the evaporation chamber 102 and extends to the drain pan 14. Accordingly, the condensed water collected at the bottom of the evaporation chamber 102 is collected to the drain pan 14 through the drain hose 141.

On the other hand, at least the front of the outside door 12 is exposed to the outside, whereby the authenticated express driver can open the outside door 12. The front surface of the outer door 12 may be formed in the same plane as the front surfaces of the first and second storage containers 5 and 6 or slightly protrude therefrom. Alternatively, the front face of the outer door 12 may be designed to form the same plane or a slightly convex shape as the outer wall 1.

Also, the outer door 12 may not provide a handle structure to prevent an unauthorized person from opening. For example, a control unit provided on the control panel 4 or the vestibule refrigerator 10 releases the locked state of the outer door 12 when a delivery article is recognized and authenticated by an authentication device mounted on one side of the outer door 12 or the control panel 4. The control part may rotate the outer door 12 forward by a prescribed angle by driving a driving mechanism for pushing an additional setting of the outer door 12, so that the express driver can easily open the outer door.

In addition, if the express driver closes the outside door 12 after keeping the articles, the control unit may return the outside door to the locked state.

In fig. 3, a distance M from the front end of the case 11 to the left side surface of the inner door 13 may correspond to the thickness of the outer wall 1. Although a hinge (described later) of the inner door 13 may be provided to the case 11, it is not excluded that the hinge is provided to a portion other than the case 11 including the outer wall 1.

The hinge 124 of the inner door 13 may be provided in the case 11, or may be provided in a portion other than the case 11 including the outer wall 1.

In addition, the case 11 includes: a housing 111 forming an external appearance; an inner case 112 disposed inside the outer case 111, which defines the storage chamber 101; and a heat insulating material 113 filled between the outer case 111 and the inner case 112.

A plurality of protrusions 112i may protrude from the bottom surface of the inner case 112. The plurality of protrusions 112i may extend from a front end to a rear end of the inner case 112 and protrude upward from a bottom surface of the inner case 112.

The plurality of protruding portions 112i may be arranged at predetermined intervals in the width direction of the inner case 112.

Since the plurality of projections 112i are formed on the bottom surface of the inner case 112, when a heavy shipping article is pushed into the storage chamber 101, the shipping article and the bottom surface of the inner case 112 are in substantially line contact, and thus friction force can be minimized.

The plurality of protrusions 112i may be dots (dots) or hemispherical protrusions, and the protrusions may be arranged at predetermined intervals, so that the lower surface of the article to be delivered is substantially in point contact with the protrusions, thereby further reducing friction.

An outer seal 31 is attached to a portion of the front surface of the case 11 corresponding to the edge of the outer opening 114, and an inner seal 32 is attached to a portion of the side surface of the case 11 corresponding to the edge of the inner opening 115. The outer seal and the inner seal are understood to be an outer gasket or an inner gasket.

In addition, an inside air guide 18 is installed at the rear surface of the guide plate 17, thereby guiding the cool air supplied from the cool air supply module 20 to the storage chamber 101.

On the other hand, the cool air supply module 20 includes a cool air supply mechanism using a thermoelectric element, one surface of which functions as a heat absorbing surface that absorbs heat by cooling down and the opposite surface of which functions as a heat generating surface that radiates heat by heating up when current is applied.

The cool air supply module 20 may include: a thermoelectric element 21; cold side heat sinks (cold sink) 22 attached to the heat absorbing surfaces of the thermoelectric elements 21; a hot side heat sink (heat sink) 24 attached to the heat generating surface of the thermoelectric element 21; a heat absorbing fan 23 disposed in front of the cold end radiator 22; a heat radiation fan 25 disposed at the rear of the hot end radiator 24; and a heat insulating block 26 surrounding an edge of the thermoelectric element 21.

In detail, as shown in fig. 7, the cold air supply module 20 may be mounted to a mounting hole formed at the rear surface of the case 11. In the case where the pair of cold air supply modules 20 are disposed vertically, a first cold air supply module may be disposed below the rear surface of the case 11, and a second cold air supply module may be mounted on the rear surface of the case 11 at a position spaced upward from the first cold air supply module.

The inside air guide 18 may be disposed between the heat absorbing fan constituting the first cool air supply module and the heat absorbing fan constituting the second cool air supply module. The cold air flowing by the heat absorbing fan of the first cold air supply module and the cold air flowing by the heat absorbing fan of the second cold air supply module may be supplied to the storage compartment without being mixed by the internal air guide 18.

At least one or both of the heat absorption fan 23 and the heat radiation fan 25 is an axial flow fan or a centrifugal fan.

The cold side radiator 22 includes a radiator body and a plurality of heat exchange fins arranged at a front surface of the radiator body. The rear surface of the radiator body is closely attached to the front surface of the thermoelectric element 21, and the heat exchange fins are rectangular and vertically arranged on the front surface of the radiator body. The plurality of heat exchange fins are arranged at intervals in the width direction of the radiator main body. Accordingly, the cold air sucked into the storage chamber 101 by the heat absorption fan 23 collides with the front surface of the radiator body and then dispersedly flows in the up-down direction through the flow paths formed between the plurality of heat exchange fins. The cold air cooled by heat exchange with the cold end radiator 22 is supplied to the storage chamber 101 along the inside air guide 18 after passing through the discharge grill 171 formed on the guide plate 17.

In addition, as with the cold side heat sink 22, the hot side heat sink 24 may include a heat sink body having a rear surface attached to the heat generating surface of the thermoelectric element 21 and a plurality of heat exchange fins extending from a front surface of the heat sink body.

Since the heat exchange amount of the hot side radiator 24 must be greater than that of the cold side radiator 22, the volume of the hot side radiator 24 may be greater than that of the cold side radiator 22, and a heat conductive member such as a heat pipe may be installed inside the hot side radiator 24. This is a physical characteristic that the cooling capacity (cooling capacity) of the thermoelectric element is reduced as the temperature difference between the heat absorbing surface and the heat generating surface becomes larger. Therefore, in order to maximize the freezing capacity of the thermoelectric element 21, the heat dissipation capacity of the hot side heat sink 24 is set to be greater than the heat absorption capacity of the cold side heat sink 22.

In addition, the heat exchange fins of the hot-side radiator 24 extend laterally and are arranged to be spaced apart in the up-down direction, so that the external air (indoor air) sucked by the heat radiation fan 25 collides with the front surface of the radiator body of the hot-side radiator 24 and then flows separately in the left-right direction.

In particular, after the lower hot-end radiator 24 collides with the bottom surface of the outside air guide 16 and exchanges heat, the heat radiation air split to the left and right is guided by the outside air guide 16 and flows separately to the left and right of the heat radiation cover 15.

On the other hand, after the condensed water formed on the front surface of the cold-end radiator 22 flows to the bottom of the evaporation chamber 102, it is collected to the drain pan 14 via the drain hose 141. The drain hose 141 may penetrate the case 11 from the bottom surface of the inner case 112 defining the bottom of the evaporation chamber 102, and extend toward the drain pan 14.

Fig. 9 is a rear perspective view of an external door of a vestibule refrigerator constituting an embodiment of the present invention.

Referring to fig. 9, the exterior door 12 of the vestibule refrigerator 10 according to an embodiment of the present invention may include a door body 121 and a door liner 122 protruding from the rear surface of the door body 121.

The door body 121 may be made of a metal material that is fire-resistant, i.e., has a fireproof function in the event of a fire in an outdoor corridor. Inside the door body 121 may be filled with a refractory block.

In addition, the door liner 122 is a portion that enters the inside of the storage chamber 101 through the outside opening 114 after the outside door 12 is closed. Accordingly, the inside of the door liner 122 may be filled with heat insulating foam to prevent cool air of the storage compartment 101 from leaking to the outside through heat conduction.

After the outer door 12 is closed, the outer seal 31 surrounding the edge of the outer opening 114 is abutted against the back surface of the door body 121. Specifically, the leakage of cold air is prevented by the outer seal 31 being closely adhered to the edge portion of the door liner 122.

In addition, the hinge 124 may be installed at one side of the door body 121 (or one side of the outer door), and the latch groove 123 may be formed at the other side of the door body 121 (or the other side of the outer door). The door latch, which maintains the outer door 12 in a locked state by being inserted into the latch groove 123, may be provided at a partition 7 for partitioning the vestibule refrigerator 10 and the vestibule door 3.

In detail, the door latch may be provided in a horizontal direction at a side surface of the partition 7 opposite to the other side surface of the door body 121, and may be drawn out of the partition 7 or may be drawn into the inside of the partition 7.

Conversely, the door latch may be provided so as to be able to be introduced/withdrawn inside the door body 121, with a latch groove formed in a side surface of the partition 7.

Fig. 10 is a rear perspective view of an inner door of a vestibule refrigerator constituting an embodiment of the present invention.

Referring to fig. 10, the interior door 13 of the vestibule refrigerator 10 according to the embodiment of the present invention may include a door body 131 and a door liner 132 disposed at the rear surface of the door body 131.

In detail, the door body 131 and the door liner 132 may be formed of a plastic material, and may be filled with a heat insulating material therein. The door body 131 may be formed of a metal material according to design conditions.

The door liner 132 protrudes from the rear surface of the door body 131 by a predetermined thickness, and after the inner door 13 is closed, the door liner 132 enters the inside of the storage chamber 101 through the inner opening 115.

After the inner door 13 is closed, the inner seal 32 around the edge of the inner opening 115 is abutted against a portion of the back surface of the door body 131 corresponding to the edge of the door liner 132.

A hinge 133 is mounted on one side of the door 131, and the hinge 133 may be fixed to the outer wall 1 or the case 11. Since the front end portion of the case 11 is fitted into the outer wall 1, one side surface of the inner door 13, i.e., the side surface to which the hinge 133 is attached, may be spaced apart from the front end portion of the case 11 by a predetermined distance M (see fig. 3).

The other side surface of the inner door 13, which is the opposite side surface to the side surface to which the hinge 133 is attached, may be positioned further to the rear side than the rear end portion of the housing 11. That is, a side end portion defining the other side surface of the inner door 13 may extend further to the rear side of the case 11 than the rear end portion of the case 11, and be adjacent to the third storage box 8. According to this structure, there is an advantage that the members provided on the rear surface of the case 11, including the heat radiation cover 15, the drain pan 14, the outside air guide 16, and the like, are prevented from being exposed to the outside.

In more detail, the back surface of the door body 131 may include: a left back surface 137 extending from one side surface of the door body 131 to one side surface of the door liner 132; a right side back portion extending from the other side surface of the door body 131 to the other side surface of the door liner 132; an upper back surface portion 138 extending from an upper end of the door body 131 to an upper end of the door liner 132; and a lower back surface portion 139 extending from a lower end of the door body 131 to a lower end of the door liner 132.

In addition, the right back portion may include: a first right back surface 134 that is in close contact with the side surface of the case 11 after the inner door 13 is closed; and a second right back surface portion 135 extending from an edge of the first right back surface portion 134 to the other side surface of the door body 131.

A latch groove 136 may be formed at the first right rear surface portion 134, and a door latch may be provided in the case 11 at an inner portion corresponding to the latch groove 136. That is, a locking device for locking the inner door 13 may be provided in the first right rear surface 134 and the case 11 corresponding thereto.

The second right back surface 135 is a portion extending rearward from the rear end of the housing 11, and serves to block the space between the back surface of the housing 11 and the third storage box 8.

In addition, the upper and lower width L1 of the upper back surface portion 138 may be smaller than the upper and lower width L2 of the lower back surface portion 139. This is because, as shown in fig. 8, the length from the lower end of the side face of the case 11 to the lower end of the inner opening 115 is longer than the thickness of the case 11.

The lower end portion of the inner opening portion 115 is formed to be higher than the bottom surface of the storage chamber 101, whereby, when the inner door 13 is opened, it is possible to minimize the leakage of the cold air, which is settled to the bottom surface of the storage chamber 101, to the outside through the inner opening portion 115, and thus it is possible to minimize the loss of the cold air.

Of course, in order to minimize such a cold air leakage phenomenon, the lower end portion of the outer opening 114 may be designed to be higher than the bottom surface of the storage chamber 101.

Fig. 11 is a front perspective view of a guide plate constituting a vestibule refrigerator according to an embodiment of the present invention, and fig. 12 is a rear perspective view of the guide plate.

Referring to fig. 11 and 12, the guide plate 17 of the embodiment of the present invention may include: a rectangular plate body 172; a bending part 173 that bends backward from the edge of the plate body 172; at least one pair of reinforcing ribs 174 protruding from the rear surface of the plate body 172 and extending from the upper end to the lower end of the plate body 172. The bending part 173 is closely attached to the inner surface of the inner housing 112.

The distance from the left side edge of the plate body 172 to any one of the pair of reinforcing ribs 174 may be equal to the distance from the right side edge of the plate body 172 to the other reinforcing rib 174 of the pair of reinforcing ribs 174.

In addition, a plurality of grids may be disposed in the plate 172 at positions corresponding to between the pair of reinforcing ribs 174, the grids being spaced apart in the up-down direction, that is, in the longitudinal direction of the plate 172.

The grill is understood to be a structure including an opening portion formed in the plate body 172 and a plurality of vertical ribs formed in the opening portion. The plurality of vertical ribs may be arranged at intervals in a width direction defining the opening portion of the grill.

The plurality of gratings may include: a plurality of discharge grilles 171 formed in the center of the plate body 172, in the upper side edge portion of the plate body 172, in the lower side edge portion of the plate body 172, and in the plurality of suction grilles 175, respectively, and formed between the discharge grilles 171 adjacent to each other in the up-down direction.

The plurality of spit-out grills 171 may include: an upper discharge grill formed near an upper side edge of the plate body 172; a center discharge grill formed in the center of the plate 172; and a lower discharge grill formed near the lower side edge of the plate 172.

The length of the opening portion defining the center discharge grill in the vertical direction may be twice the length of the opening portion defining the upper discharge grill in the vertical direction, and the length of the opening portion defining the upper discharge grill in the vertical direction may be equal to the length of the opening portion defining the lower discharge grill in the vertical direction.

The plurality of suction grills 175 can include: an upper suction grill formed between the upper discharge grill and the central discharge grill; and a lower suction grill formed between the central discharge grill and the lower discharge grill. The upper suction grill and the lower suction grill may be designed to be equal in size.

On the rear side of the plurality of suction grills 175, heat absorbing fans 23 respectively constituting the cool air supply module 20 may be disposed.

The support rib 176 extends from an edge defining the opening of the suction grill 175 to form a fan receiving portion having a quadrangular shape. A front portion of the heat absorbing fan 23 is accommodated in a fan accommodating portion defined by the support rib 176.

The inner air guide 18 may be attached to a portion of the rear surface of the plate 172 corresponding to the center of the center discharge grill. When the heat absorption fan 23 is driven, cool air of the storage chamber 101 flows into the evaporation chamber 102 through the upper suction grill and the lower suction grill and collides with the front surface of the cold end radiator 22.

The temperature of the cold air colliding with the cold-end radiator 22 is lowered by heat exchange, and then dispersed and flowed in the up-down direction of the cold-end radiator 22. A part of the cool air dispersed and flowing in the up-down direction of the cold end radiator 22 is re-flowed into the storage chamber 101 through the upper and lower discharge grills.

On the other hand, the cool air flowing along the inside air guide 18 flows again into the storage compartment 101 through the center discharge grill.

Here, the suction flow path and the discharge flow path of the cool air may be reversed according to the type of the heat absorbing fan 23, and in this case, the suction grill may function as the discharge grill, and the discharge grill may function as the suction grill.

Fig. 13 is a rear perspective view of an inside air guide of a vestibule refrigerator constituting an embodiment of the present invention.

Referring to fig. 13, the interior air guide 18 of an embodiment of the present invention may include: an upper guide 181 extending from a front end to a rear end in an arc shape curved upward; a lower guide 182 extending from a front end to a rear end in an arc shape curved downward; and a flange 183 extending vertically from a side surface of a front end portion where the upper guide 181 and the lower guide 182 meet.

The front end portion of the upper guide 181 may be intersected with and formed as one body with the front end portion of the lower guide 182.

The upper guide 181 and the lower guide 182 may be formed in an arc shape or an inclined shape in a vertically symmetrical shape with respect to a horizontal plane passing through a portion where the front ends of the upper guide 181 and the lower guide 182 meet, i.e., a horizontal plane dividing the inside air guide 18 up and down.

Specifically, the upper guide 181 is formed in an arc shape such that a slope of a tangent line of a rear surface of the upper guide 181 gradually increases as approaching from a front end portion to a rear end portion.

Alternatively, the upper and lower guides 181 and 182 may extend obliquely upward and downward, respectively, at equal angles from the horizontal plane bisecting the inner air guide 18 up and down.

Here, the rear surface of the upper guide 181 and the rear surface of the lower guide 182 may be defined as two surfaces opposite to each other, and opposite surfaces of the rear surface may be defined as the front surface of the upper guide 181 and the front surface of the lower guide 182, respectively.

The flange 183 may extend at left and right ends of the upper and lower guides 181 and 182 to be coupled with the pair of reinforcing ribs 174 formed at the rear surface of the guide plate 17.

Specifically, the front end portion of the inside air guide 18 may be disposed at a position that vertically bisects the center discharge grill of the guide plate 17. Thus, the cold air forced to flow by the upper heat absorbing fan 23 and the cold air forced to flow by the lower heat absorbing fan 23 can be discharged to the storage chamber 101 substantially uniformly through the central discharge grill.

The flange 183 may be fixedly attached to the reinforcing rib 174 by bolts (not shown) penetrating the reinforcing rib 174. As another method, the flange 183 may be attached to the reinforcing rib 174 using an adhesive member.

As another method, the front end portion where the upper guide 181 and the lower guide 182 intersect may be directly attached to the rear surface of the guide plate 17 without the flange 183.

Further, an interference prevention groove 182a may be formed at a rear end portion of a rear surface of the lower guide 182, and a function of the interference prevention groove 182a will be described in detail with reference to the accompanying drawings.

Fig. 14 is a cross-sectional perspective view showing a rear wall of an inner case constituting a cabinet of a vestibule refrigerator of an embodiment of the present invention, and fig. 15 is a rear perspective view of the rear wall of the inner case.

Referring to fig. 14 and 15, in a rear wall of an inner case 112 of a cabinet 11 constituting a vestibule refrigerator 10 of an embodiment of the present invention, through holes are formed to which one or more cool air supply modules 20 are mounted.

Specifically, when the pair of cold air supply modules 20 are mounted to the rear wall of the casing 11, the upper through-hole 112a and the lower through-hole 112b may be formed in the rear wall of the casing 11, respectively.

A center recess 112f may be formed at the center of the rear wall of the inner case 112, the center recess 112f having a prescribed width and having a length from the upper end to the lower end of the rear wall of the inner case 112. The central groove 112f may be formed by a molding process such that a portion of the rear wall of the inner case 112 is recessed rearward or stepped.

The upper end of the upper through hole 112a is spaced a predetermined distance downward from the upper end of the central groove 112f, and the lower end of the lower through hole 112b is spaced a predetermined distance upward from the lower end of the central groove 112 f.

In addition, an upper guide portion 112g is formed between an upper end of the central groove 112f and an upper end of the upper through hole 112a at a portion defining the central groove 112f in a rear wall of the inner case 112, and the upper guide portion 112g is formed in an arc shape protruding rearward or a stepped shape bent a plurality of times.

Similarly, a lower guide portion 112h is formed from the lower end of the central groove 112f to the lower end of the lower through hole 112 a.

The upper and lower guide portions 112g and 112h may be understood as portions formed to guide the flow of air sucked by the heat absorption fan 23 and rising or falling along the cold end radiator 22 toward the discharge grill 171 side of the guide plate 17.

Therefore, if the upper and lower guide portions 112g and 112h are designed to be bent toward the front of the inner case 112 in a gentle arc, it is possible to minimize flow resistance occurring in the process of guiding the cooled air passing through the cold-end radiator 22 toward the storage chamber 101.

On the other hand, a guide protrusion 112c for guiding the flow of the condensed water may be formed at a portion of the rear wall of the inner case 112 corresponding to between the upper through hole 112a and the lower through hole 112b, and the guide protrusion 112c may protrude forward.

In detail, the guide protrusion 112c may be formed in a shape in which the width thereof gradually becomes narrower as approaching the upper through hole 112 a. Specifically, the guide projection 112c includes a left inclined portion 112d and a right inclined portion 112e, and an upper end of the left inclined portion 112d and an upper end of the right inclined portion 112e intersect and form a tip.

The left inclined portion 112d and the right inclined portion 112e may extend from a portion spaced upward from the lower through hole 112 b. In other words, the guide projection 112c extends in a shape in which the width gradually becomes narrower from a certain portion while forming the left inclined portion 112d and the right inclined portion 112e in a way of extending vertically upward in a shape in which the predetermined width is maintained from the upper end of the lower through hole 112 b.

According to this structure, condensed water or defrost water flowing down from the front surface of the cold end radiator 22 of the cold air supply module 20 mounted to the upper through hole 112a flows down toward the bottom surface of the inner case 112 along the left and right side edges of the guide protrusion 112 c.

In detail, the condensed water or defrost water flows toward the bottom surface of the inner case 112 along a left side flow path 112j formed between the left side edge of the central groove 112f and the left side edge of the guide protrusion 112c and a right side flow path 112k formed between the right side edge of the central groove 112f and the right side edge of the guide protrusion 112 c.

Here, the condensed water or defrost water flowing down the upper end of the guide protrusion 112c flows along the left and right inclined portions 112d and 112e to the left and right side flow paths 112j and 112k, respectively.

Further, a drain hole 112m is formed at a portion where the rear wall and the bottom surface of the inner case 112 intersect, and one end of the drain hose 141 is connected to the drain hole 112 m. Accordingly, condensed water or defrost water flowing toward the bottom surface of the inner case 112 is collected to the drain pan 14 along the drain hose 141.

As another example, the left inclined portion 112d and the right inclined portion 112e may extend from the upper end of the lower through hole 112b, and the guide protrusion 112c may be formed in a triangular protrusion shape.

In this way, the condensed water or defrost water flowing down from the upper cold-end radiator 22 flows down along both side end portions of the cold-end radiator constituting the lower cold-air supply module 20, and it is possible to minimize the flow resistance applied to the condensed water by the cold air forcibly flowing by the heat absorption fan 23.

Specifically, the cold air flowing from the storage chamber 101 into the evaporation chamber 102 by the heat absorbing fan 23 directly collides with the front surface of the cold end radiator 22 and then flows upward and downward. As approaching from the center of the front surface of the cold end radiator 22 to both side ends, the flow rate of the cold air colliding with the front surface of the cold end radiator 22 is relatively slow.

Therefore, the cold air rising after colliding with the front surface of the cold-end radiator of the cold-air supply module 20 mounted to the lower through hole 112b can push up the condensed water or defrost water flowing down from the upper cold-end radiator 22, thereby generating flow resistance.

At this time, if the flow of the condensed water or the defrost water is dispersed to the left-side flow path 112j and the right-side flow path 112k, there is an effect of minimizing the flow resistance of the condensed water or the defrost water acting on the downward flow.

Fig. 16 is an enlarged cross-sectional view of portion a of fig. 7.

Referring to fig. 16, as shown by solid arrows, when the heat absorption fan (upper heat absorption fan) of the first cool air supply module and the heat absorption fan (lower heat absorption fan) of the second cool air supply module are driven, cool air of the storage chamber 101 is sucked into the evaporation chamber 102 through the guide plate 17.

The flow direction of the cool air sucked into the evaporation chamber 102 is changed by 180 degrees by the upper guide 181 and the lower guide 182. That is, the cool air sucked by the heat absorption fan is dispersed up and down by collision with the front surface of the radiator body of the cold end radiator 22.

After that, the flow direction of the cold air dispersed up and down is changed to be directed toward the storage chamber side by the upper guide 181 and the lower guide 182. The cold air whose flow direction is changed is discharged to the storage chamber 101 through the guide plate 17.

On the other hand, the rear end of the upper guide 181 constituting the inside air guide 18 is spaced apart from the rear wall of the inner case 112 defining the central groove 112 f. This is to prevent the flow of condensed water or defrost water flowing down along the rear wall of the inner case 112 as indicated by the dotted arrow from being blocked by the upper guide 181.

If the rear end of the upper guide 181 contacts the rear wall of the inner case 112, condensed water or defrost water moves along the front surface of the upper guide 181 toward the front end of the upper guide 181. And, the condensed water or defrost water flowing on the front surface of the upper guide 181 flows down along the guide plate 17 toward the bottom surface of the storage chamber 101. This causes the condensed water flowing toward the bottom surface of the inner case 112 not to flow toward the drain hole 112m formed at the bottom of the evaporation chamber 102, and thus to remain on the bottom surface of the storage chamber 101. This phenomenon causes mold formation and odor generation in the storage chamber 101.

On the other hand, the rear end of the lower guide 182 is in contact with the guide protrusion 112c, and the interference preventing groove 182a formed at the rear end of the rear surface of the lower guide 182 may be defined as a groove accommodating the guide protrusion 112 c. Accordingly, the interference prevention groove 182a may be formed to have a width corresponding to the width of the guide protrusion 112 c.

Of course, left and right edges of the rear end portion of the lower guide 182 are spaced apart from the rear wall of the inner housing 112 defining the left and right side flow paths 112j and 112 k.

On the other hand, the front surface of the rear wall of the inner case 112 from the lower end of the upper through hole 112a to the upper end of the lower through hole 112b may be formed to be inclined in a shape protruding forward gradually as approaching downward. Such an inclined structure may be equally applicable to the rear wall of the inner housing 112 defining the left-side flow path 112j and the right-side flow path 112 k.

According to such an inclined structure, it is possible to minimize a phenomenon in which condensed water or defrost water falling from the cold-end radiator 22 of the first cold-air supply module 20 directly collides with the cold-end radiator 22 of the second cold-air supply module 20 to splash.

That is, the condensed water can flow to the front surface of the cold-end radiator 22 of the second cold-air supply module 20 along the inclined rear wall of the inner case 112, thereby having an effect of minimizing the splashing phenomenon of the condensed water.

Fig. 17 is a perspective view of a baffle constituting an article storage system for vestibule according to an embodiment of the present invention, fig. 18 is a longitudinal sectional view of the baffle taken along line 18-18 of fig. 17, fig. 19 is a sectional view of the article storage system for vestibule taken along line 19-19 of fig. 2, and fig. 20 is a sectional view of the article storage system for vestibule taken along line 20-20 of fig. 2.

Referring to fig. 17 and 18, the baffle 40 according to the embodiment of the present invention is a plate having a width corresponding to a space between the rear surface of the vestibule refrigerator 10 and the side surface of the third storage box 8 opposite to the rear surface, a length corresponding to the height of the third storage box 8, and a predetermined thickness.

The surface of the baffle 40 exposed to the room in the mounted state may be defined as a front surface (or an outer side surface), and the opposite surface of the front surface may be defined as a rear surface (or an inner side surface).

The front face of the shutter 40 may be formed in the same plane as the front face of the third internal door 8 a. Alternatively, as shown in the drawing, a vertical plane passing through the front surface of the shutter 40 and a vertical plane passing through the front surface of the third internal door 8a may be planes parallel to each other at intervals.

A plurality of suction holes 41 may be formed in a lower end region of the baffle 40, and a plurality of discharge holes 42 may be formed in an upper end region. That is, the plurality of suction holes 41 may be formed in a lower region and the plurality of discharge holes 42 may be formed in an upper region with respect to a line bisecting the baffle 40 vertically.

A filter F capable of filtering foreign substances contained in the air sucked through the plurality of suction holes 41 is installed at a portion corresponding to a portion where the plurality of suction holes 41 are formed in the rear surface of the baffle 40. Thereby, the amount of foreign matter flowing into the cooling fan 25 is significantly reduced, and the lifetime of the cooling fan 25 can be prolonged.

The plurality of suction holes 41 may be formed to be inclined upward from the front surface toward the rear surface of the barrier 40. Thus, when the indoor air of the vestibule flows into the gap between the vestibule refrigerator 10 and the third storage box 8, the indoor air is guided to the heat radiation cover 15 side of the vestibule refrigerator 10 and rises.

In addition, the plurality of discharge holes 42 may be inclined upward from the rear surface of the baffle 40 toward the front surface. Thereby, the hot air discharged from the heat radiation cover 15 and raised is continuously discharged from the slit to the ceiling side of the vestibule. Therefore, not only can the flow resistance of the discharged air be minimized, but also there is an advantage in that the direct contact of the hot gas with the user can be prevented.

As shown in fig. 19 and 20, the indoor air flowing into the slit through the suction hole 41 is purified and then rises up to flow toward the radiator cover 15 side when flowing through the filter F, and the relatively high-temperature hot air discharged from the radiator cover 15 rises up through the discharge hole 42 and is discharged toward the ceiling of the vestibule.

Further, a duct penetrating a wall separating an indoor space and an outdoor space is provided at the ceiling of the vestibule, whereby air discharged toward the ceiling of the vestibule can be discharged to the outdoor space.

Here, the hot-side radiator 24 and the heat dissipation fan 25 constituting the cold air supply module 20 may be defined as a heat generating portion (or a heat dissipating portion), and the cold-side radiator 22 and the heat absorption fan 23 may be defined as a heat absorbing portion. Accordingly, the cool air supply module 20 may be understood as being composed of the thermoelectric element 21, the heat absorbing portion, and the heat generating portion (or the heat dissipating portion). The heat generating portion is exposed to the outside of the rear surface of the case 11, and the heat absorbing portion is accommodated in the case 11.

The first, second, and third storage tanks 5, 6, and 8 described above are not limited in order, and any one of the three storage tanks 5, 6, and 8 may be interpreted as a first storage tank, while the other is a second storage tank, and the remaining one is a third storage tank.
