  In recent years, a demand for a refrigerator having a larger capacity of a frozen storage space has been increasing. In response, refrigerators that use the entire lower part of the refrigerator as a freezing storage space are becoming popular. Among such refrigerators, for a refrigerator having a relatively narrow width, a configuration in which a vegetable room, which has been often arranged at the bottom in the related art, is arranged as an isolation room in a refrigerator room in the upper stage is being studied.

  For example, when the above-described configuration is applied to the refrigerator 1 of Patent Literature 1, two isolation rooms, a chilled room and a vegetable room, are arranged below and above the refrigerator compartment 2 in two stages. As a result, the partition plate for forming the isolation chamber is arranged up to the upper portion in the refrigerator compartment. Such a partition plate is heavier than the movable mounting shelf 45 arranged in the refrigeration space above the refrigeration compartment 2. Further, unlike the movable mounting shelf 45, such a partition plate is usually required to stably maintain a fixed state without being removed.

  However, when the partition plate is directly fixed to the resin inner box constituting the side surface in the refrigerator compartment 2 with screws or the like, the screws are exposed in the refrigerator, and the appearance is impaired.

  Therefore, as another method, it is conceivable to fix a partition plate on the back surface of the refrigerator compartment 2. However, some refrigerators have a cooling plate provided on the back of the refrigerator compartment. For example, Patent Literature 2 discloses a refrigerator 1 having a cooling plate 42 formed on a front surface of a cooling passage 29 by sheet metal processing of a metal plate such as aluminum or stainless steel.

  Such a cooling plate is a thin plate-shaped member attached to the surface of the cooling passage 29. Therefore, when a member for fixing the partition plate is provided on the cooling plate and the partition plate is fixed, there is a problem that the cooling plate is distorted when, for example, the partition plate is pulled forward.

  Then, in this invention, it aims at providing the refrigerator which can hold the partition plate arrange | positioned in a storage room more stably.

  A refrigerator according to one aspect of the present invention includes a storage room, a partition plate that partitions the storage room, an insulated box provided around the storage room, and a passage through which cool air passes. And a fixing member for fixing the partition plate to the heat-insulating box. The partition plate is fixed to the back surface of the heat insulating box by the fixing member while being arranged so as to straddle the passage constituting member.

  In the refrigerator of the present invention described above, a holding member for holding the partition plate may be further provided between the partition plate and the passage constituting member, and the fixing member may be attached to the holding member.

  In the refrigerator of the present invention, the fixing member may penetrate the passage constituting member.

  In the refrigerator of the present invention described above, the fixing member may penetrate the passage forming member avoiding the passage.

  In the refrigerator of the present invention described above, a plate member may be provided in the storage room so as to cover the passage constituting member.

  According to the present invention, the partition plate can be fixed to the back surface of the heat insulating box by the fixing member. Therefore, the partition plate arranged in the storage room of the refrigerator can be held more stably. Thereby, the strength of the partition plate can be maintained.

Further, in this specification, when the term “front side” or “back side” is defined, the front side or the back side provided with an arbitrary position as a reference, or the front side or the rear side from any position Means direction. The direction from the front to the back or from the back to the front is called the front-back direction.

  The refrigerator 1 is provided with a heat insulating box 50 as a heat insulating structure for insulating each storage space from the surroundings (see FIG. 2). The heat insulating box 50 is provided so as to cover the outer periphery of the refrigerator 1. As shown in FIG. 2, the heat insulating box 50 mainly includes an outer box 51, an inner box 52, and a heat insulating layer 53.

  The outer box 51 forms an outer peripheral surface of the heat insulating box 50. The outer box 51 also partially forms the outer shape of the refrigerator 1. The inner box 52 forms the inner peripheral surface of the heat insulating box 50. The inner box 52 forms an inner wall of each storage space (for example, the refrigerator compartment 11, the first freezer compartment 12, and the like). The heat insulating layer 53 is composed of, for example, a vacuum heat insulating material and a foam heat insulating material. The vacuum heat insulating material is a thin sheet or plate heat insulating material. The foam heat insulating material can be formed of, for example, foamed polyurethane.

  In the refrigerator compartment 11, a plurality of refrigerator shelves 21, 22, 23 and partition shelves (partition plates) 24, 25 are arranged in order from the top. The movable shelves 21, 22, and 23 are mounted on protrusions provided on the inner wall in the refrigerator compartment 11. The plurality of protrusions are provided on the inner wall surface (see FIG. 4). Therefore, by appropriately changing the projection used by the user, the placement position of the movable shelves 21, 22, 23 can be changed.

  The partition shelves 24 and 25 are fixed to the inner wall of the refrigerator compartment 11 and cannot be removed during normal use. As will be described later, the partition shelf 24 is fixed to the inner box 52 on the back side of the refrigerator compartment 11 via the holding member 32. The partition 25 is also attached to the inner wall of the refrigerator compartment 11 like the partition 24.

  As shown in FIG. 2, a chilled case 15a is arranged between the partition shelf 24 and the partition shelf 25. A chilled chamber 15 is formed by the chilled case 15a and the partition shelf 24. The partition shelf 24 forms the upper surface of the chilled chamber 15.

  As shown in FIG. 2, a fruit case 16a and a vegetable case 17a are arranged in order from the top below the partition 25 corresponding to the bottom of the refrigerator compartment 11. Then, the vegetable case 17 is formed by the fruit case 16a, the vegetable case 17a, and the partition 25. The partition 25 constitutes the upper surface of the vegetable compartment 17. Above the vegetable compartment 17, a fruit case 16 including a fruit case 16a is provided.

  As described above, the partition shelf 24 is provided on the upper surface of the chilled room 15, so that the chilled room 15 can be a storage space shielded from the refrigerator compartment 11. Thereby, the temperature in the chilled chamber 15 can be adjusted to a temperature different from the temperature of the refrigerator compartment 11.

  In addition, since the partition shelf 25 is provided on the upper surface of the vegetable compartment 17, the vegetable compartment 17 including the fruit compartment 16 can be a storage space shielded from the refrigerator compartment 11. Thereby, it can suppress that cold wind hits the vegetable room 17 directly and the stored thing in a vegetable room dries.

  Further, in the refrigerator 1 according to the present embodiment, a water supply tank 18 is arranged next to the chilled room 15. Water is stored in the water supply tank 18 and is used when ice is made in the ice making room 13 located at the lower stage.

The location where the water supply tank 18 described above is installed is an example, and the present invention is not limited to this.

  Further, one or a plurality of storage cases can be installed in the first freezer compartment 12 and the second freezer compartment 14. Thereby, each storage room can be divided into a plurality of storage spaces.

  On the back side of the refrigerator compartment 11, a shower duct component 30 is arranged. Inside the shower duct component (passage component) 30, a shower duct 30a, which is a passage for cool air, is provided. The shower duct component (passage component) 30 has a plurality of outlets 46a, 46b, 46c, 46d, and 46e formed in a vertical direction. As will be described later, cool air from the evaporator 41 blows into the refrigerator compartment 11 from the outlets 46a, 46b, 46c, 46d, 46e.

  Further, inside the refrigerator compartment 11, the surface of the shower duct component 30 is covered with a cooling plate (plate-like member) 31. The cooling plate 31 is formed of a metal plate having a high thermal conductivity. The cooling plate 31 is a thin plate-shaped member having a rectangular front surface, and is attached to the shower duct component 30 so as to follow the surface shape of the shower duct component 30. The provision of the cooling plate 31 on the back surface of the refrigerator compartment 11 allows radiation stored in the refrigerator compartment 11 to be cooled by radiation.

  In the refrigerator of the present invention, the cooling plate 31 may not be provided. Further, in the refrigerator of the present invention, instead of the cooling plate 31, a decorative plate whose surface is decorated may be provided. Thereby, the beauty in the refrigerator compartment 11 can be improved. When a decorative plate is used instead of the cooling plate, it is desirable to form the decorative plate with a material having relatively high thermal conductivity.

  The chilled case 15a, the fruit case 16a, and the vegetable case 17a are slidable in the front-rear direction with respect to the inner box 52. For example, the user pulls out the chilled case 15a forward and puts meat and dairy products into the chilled case 15a. In addition, the user pulls out the fruit case 16a and puts the fruit in the fruit case 16a. The user pulls the vegetable case 17a forward and puts vegetables in the vegetable case 17a.

  A cooling room 40 is disposed on the back side of the first freezing room 12 and the second freezing room 14. In the cooling chamber 40, an evaporator 41 constituting a refrigeration cycle, a glass tube heater 61 for defrosting the evaporator 41, and cooling for sending cool air from the evaporator 41 to the second freezing chamber 14 and the like. A fan 43 is provided. The upper part of the cooling chamber 40 communicates with the shower duct 30a.

  A damper 45 is provided between the cooling chamber 40 and the shower duct 30a. By opening and closing the damper 45, the flow of cool air toward the refrigerator compartment 11 can be turned on / off. In the shower duct 30a, a cooling fan 44 is provided above the damper 45. By operating the cooling fan 44, cool air can be sent into the refrigerator compartment 11 through the outlets 46a, 46b, 46c, 46d, 46e.

  In the cooling chamber 40, a plurality of outlets 47a, 47b, 47c, 47d are formed in a vertical direction. From the outlets 47a, 47b, 47c, 47d, cool air from the evaporator 41 is blown into the first freezing compartment 12, the ice making compartment 13, and the second freezing compartment 14.

  Subsequently, a refrigeration cycle provided in the refrigerator 1 will be described. The refrigeration cycle is configured by connecting a compressor 42, a condenser, an expander, and an evaporator (cooler) 41 via a refrigerant pipe through which the refrigerant flows. The expander includes a capillary tube (capillary tube) and an expansion valve provided on the upstream side of the capillary tube in the flow direction of the refrigerant. The compressor 42 is arranged in a machine room 60 provided on the back side of the bottom of the refrigerator 1.

  In addition, a control unit (not shown) is provided inside the refrigerator 1. This control unit controls the operation of the refrigeration cycle. That is, when the control unit drives the compressor 42, the operation of the refrigeration cycle is started, and the refrigerant circulates in a path of the compressor 42 → the condenser → the expander → the evaporator 41 → the compressor 42.

  While the refrigerant circulates through the refrigeration cycle, the evaporator 41 into which the low-temperature refrigerant flows exchanges heat with the air around the evaporator 41. By this heat exchange, cool air is generated in the cooling chamber 40.

  Next, the flow path of the cool air will be described. In FIG. 3, the flow of cool air generated by the above-described refrigeration cycle is indicated by arrows.

  The cool air cooled by the evaporator 41 is sent to the first freezing room 12, the ice making room 13, and the second freezing room 14 from the outlets 47a, 47b, 47c, 47d by the cooling fan 43. The cool air that has passed through each freezing storage space returns into the cooling chamber 40 from below the first freezing chamber 12.

  Further, when the damper 45 is released, the cool air is sent from the outlets 46a, 46b, 46c, 46d, 46e into the refrigerator compartment 11 by the cooling fan 44 while rising in the shower duct 30a. The cool air sent into the refrigerator compartment 11 cools foods and beverages in the refrigerator compartment while descending from above to below, and returns to the evaporator 41 from the return port 48 through the return duct 49.

  More specifically, in the present embodiment, the cool air sent into the refrigerator compartment 11 moves downward from the rear and upper portions of the refrigerator compartment 11 along the front portion of the refrigerator compartment 11, that is, behind the door. Then, it passes in front of the vegetable compartment 17 and below the vegetable compartment 17 and enters into the return duct 49 from the return port 48.

<About the mounting structure of the partition shelf>
Next, the mounting structure of the partition shelf 24 provided in the refrigerator compartment 11 will be described with reference to FIGS. FIG. 3 shows an internal configuration of the refrigerator compartment 11. FIG. 4 is a perspective view showing the internal configuration of the refrigerator compartment 11 with the movable shelves 21, 22, 23 and the partition shelf 24 removed.

  As described above, the inside of the refrigerator compartment 11 arranged at the upper part of the refrigerator 1 is divided into a normal refrigerator storage space, a chilled compartment 15 and a vegetable compartment 17 in order from the top. Mobile shelves 21, 22, and 23 are installed in the upper part of the refrigerated storage space, and further divide the refrigerated storage space into four sections. The outlets 46a, 46b, 46c, 46d are provided on the back of each of the divided refrigerated storage spaces.

  Further, the chilled chamber 15 is located below the partition shelf 24 which is fixedly arranged. As shown in FIG. 3, the chilled chamber 15 houses a chilled case 15a that can slide in the front-rear direction. The vegetable room 17 is located below the chilled room 15. The vegetable compartment 17 accommodates a fruit case 16a and a vegetable case 17a that can be slid in the front-rear direction.

  Further, in the refrigerator 1 of the present embodiment, a water supply tank 18 is provided on the left side of the chilled case 15a.

  FIG. 4 shows the configuration of the rear surface of the refrigerator compartment 11 with the chilled case 15a removed. As shown in FIG. 4, a fixed partition 25 is arranged between the chilled room 15 and the vegetable room 17. That is, the chilled case 15a and the water supply tank 18 are placed on the partition shelf 25. Since the partition shelf 25 is provided, the chilled room 15 and the vegetable room 17 form separate storage spaces.

  As shown in FIG. 4, a holding member 32 for fixing the partition shelf 24 is provided at a mounting position of the partition shelf 24 on the back surface of the refrigerator compartment 11. The holding member 32 is attached to the back surface of the refrigerator compartment 11 along the surface of the cooling plate 31. On the back side of the holding member 32, a shower duct component 30 is arranged.

  On the back and side surfaces of the inner box 52 that forms the inner wall of the refrigerator compartment 11, auxiliary projections 52a for stably placing the partition shelf 24 are formed along the mounting position of the partition shelf 24. ing.

  Here, a specific structure of the holding member 32 will be described with reference to FIGS. FIG. 5 shows a cross-sectional configuration of the rear part of the refrigerator compartment 11 at a position where the partition shelf 24 is attached. FIG. 6A is a perspective view showing the front side of the holding member (the side to which the partition shelf 24 is attached), and FIG. 6B shows the back side of the holding member (the side in contact with the cooling plate 31). It is a perspective view.

  The holding member 32 is fixed to the heat insulating box 50 by two screws (fixing members) 71a and 71b. As shown in FIG. 5, the two screws 71 a and 71 b penetrate the shower duct component 30 and extend from the inner box 52 of the heat insulating box 50 to the heat insulating layer 53.

  The shower duct component 30 includes a shower duct 30a, a heat insulating material 70a, and an exterior member 70 as main components. The shower duct 30a is located at the center of the shower duct component 30, and cool air passes through the inside. The heat insulating material 70a is arranged so as to surround the shower duct 30a. The heat insulating material 70a is formed of, for example, polystyrene foam. The exterior member 70 is provided so as to cover the heat insulating material 70a, and forms the outer shape of the shower duct component 30.

  As shown in FIG. 5, screws 71a and 71b for fixing the holding member 32 are arranged so as to penetrate the heat insulating material 70a of the shower duct component 30. Thus, by disposing the screws 71a and 71b so as to avoid the shower duct 30a, the cool air in the shower duct 30a is insulated through the screws 71a and 71b and the holes in which the screws are disposed. Possibility of flowing out to the box 50 side can be reduced. Further, since the screws 71a and 71b are arranged so as to avoid the shower duct 30a, the screws do not hinder the cool air passing through the shower duct.

  The number of screws for fixing the holding member 32 is not particularly limited. However, in order to stabilize the fixed state of the holding member 32, it is preferable that a plurality of screws be provided. Further, in order to attach a plurality of screws so as to avoid the shower duct 30a, it is preferable to arrange screws on the left and right sides with the shower duct 30a interposed therebetween.

  As shown in FIGS. 6A and 6B, the holding member 32 includes screw through holes 33a and 33b, a cool air outlet 34, claw portions 35a and 35b for holding partition shelves, and through portions 36a and 36b. , And flange portions 37a and 37b.

  The screw through holes 33a and 33b are holes for passing the screws 71a and 71b. In this embodiment, screw through holes 33a and 33b are provided on the right and left sides of the main body of the holding member 32, respectively, corresponding to the mounting positions of the screws 71a and 71b.

  In addition, the through portions 36a and 36b are provided to protrude from the back surface of the holding member 32, as shown in FIG. The through portions 36a and 36b are formed according to the shapes of the screw through holes 33a and 33b, respectively. That is, the through portions 36a and 36b have a cylindrical shape, and the hollow portions thereof are the screw through holes 33a and 33b.

  The cool air outlet 34 is provided at a position corresponding to the outlet 46e provided on the back surface of the refrigerator compartment 11. The cool air from the outlet 46e flows into the chilled chamber 15 through the cool air outlet 34. In the present embodiment, the cool air outlet 34 is provided below the main body (below the lower flange portion 37b). However, the arrangement position of the cool air outlet 34 is not limited to this.

  The flange portions 37a and 37b are erected on the original portion so as to be substantially perpendicular to the main body portion. The upper flange portion 37 a is provided at the upper end of the main body of the holding member 32. The lower flange portion 37b stands upright on the original portion at a predetermined distance from the upper flange portion 37a substantially in parallel with the upper flange portion 37a. The partition shelf 24 is sandwiched between the upper flange portion 37a and the lower flange portion 37b. By providing the flange portions 37a and 37b, the fixed state of the partition shelf 24 can be stabilized. Further, the strength of the structure for holding the partition shelf 24 can be increased.

  The claw portions 35a and 35b for holding the partition shelves are arranged at both left and right ends on the lower flange portion 37b. The claw portions 35a and 35b for holding the partition shelf engage with the protrusions 24a and 24b (see FIG. 7 and the like) provided on the partition shelf 24, and fix the partition shelf 24 to the holding member 32.

  As described above, in the refrigerator 1 according to the present embodiment, the partition shelf 24 is fixed to the inner box 52 of the refrigerator 1 via the holding member 32. Thereby, the fixed state of the partition shelf 24 can be stabilized. Further, the structure of the partition shelf 24 can be simplified. Then, the work of attaching the partition shelf 24 to the heat insulating box 50 can be easily performed.

  In the refrigerator 1 according to the present embodiment, screws 71 a and 71 b for fixing the holding member 32 penetrate the shower duct component 30 and are attached to the heat insulating box 50. More specifically, the screw through holes 33a and 33b through which the screws 71a and 71b pass penetrate the shower duct component 30. Therefore, the mounting position of the screw to the heat insulating box 50 is on the rear side of the shower duct component 30 and is not exposed to the refrigerator compartment 11. Therefore, even if a heat insulating material such as foamed polyurethane leaks from the screw mounting position, the possibility of exposure to the inner wall of the refrigerator compartment 11 can be suppressed.

  Further, when the surface of the shower duct component 30 is covered with the cooling plate 31 as in the refrigerator 1 according to the present embodiment, if the partition shelf 24 is fixed to the cooling plate 31, for example, There is a problem that the cooling plate is distorted when the cooling plate is pulled forward. On the other hand, in the refrigerator 1 according to the present embodiment, the holding member 32 is configured to penetrate the cooling plate 31 provided on the surface together with the shower duct component 30.

  As described above, in the refrigerator 1 according to the present embodiment, the holding member 32 for fixing the partition shelf 24 and the screws 71a and 71b (fixing members) penetrate the cooling plate 31 and the shower duct component 30, and It is fixed to the heat insulation box 50. According to this configuration, when the partition 24 is pulled forward, the stress in the front-rear direction applied to the cooling plate 31 and the shower duct component 30 can be reduced.

  Further, since the screw through holes 33a and 33b and the through portions 36a and 36b are provided, the distance between the holding member 32 and the shower duct 30a can be reliably maintained. Therefore, it is possible to prevent the shower duct 30a from being pressed and deformed via the holding member 32 when the partition shelf 24 is pressed strongly.

  In the refrigerator 1 according to the present embodiment, the screws 71a and 71b are used as fixing members for fixing the holding member 32. However, the fixing member is not limited to the screw. A nail or the like can also be used as a fixing member other than the screw. Further, a fixing member may be formed integrally with the holding member 32 as a protruding claw member or the like on the back surface of the holding member 32. In this case, for example, a protruding claw member can be provided instead of the screw through holes 33a and 33b and the through portions 36a and 36b.

However, the present invention is not limited to this.

  A water supply pipe 84 connected to a water supply pump (not shown) installed on the back of the refrigerator compartment 11 is attached to the upper lid 18a. As shown in FIG. 9, when the water supply tank 18 is correctly installed on the water supply tank mounting table 82, the water supply pipe 84 has a shape that protrudes toward the back of the refrigerator compartment 11. The distal end of the water supply pipe 84 is connected to a water supply port of a water supply pump. The water supply pipe 84 is formed so as to protrude from a projection 86 formed on the upper lid 18a of the water supply tank 18.

  By the way, the refrigerator before the present invention had a structure in which the water supply tank 18 could be mounted in the front-back direction in reverse. As a result, the user often mistakenly mounts the water supply tank 18 in the opposite direction. If the water supply tank 18 is mounted in the reverse direction, the water supply pipe 84 attached to the upper cover 18a is not connected to the water supply pump, so that there is a problem that ice cannot be made.

  Therefore, the refrigerator 1 according to the present embodiment has the first protrusion 83 on the side wall of the partition wall 81 and the second protrusion 85 on the upper lid 18a of the water supply tank 18. These projections 83 and 85 function as a reverse attachment prevention mechanism for the water supply tank.

  The first projection 83 is formed so as to project from the side surface of the partition wall 81 on the side of the water supply tank mounting table 82. In the present embodiment, the first projection 83 is an elongated projection having a certain length in the front-rear direction.

  The second protrusion 85 is provided at the front end of the upper lid 18 a of the water supply tank 18. The second protrusion 85 protrudes from the surface of the upper cover 18a along the shape of the front side of the water supply tank 18. For this reason, the user can easily pull out the water supply tank 18 by putting a finger or the like on the second protrusion 85. That is, the second protrusion 85 also functions as a grip for the water supply tank 18.

  Further, the protrusion 86 having the water supply pipe 84 formed on the upper lid 18 a of the water supply tank 18 is formed to be narrower than the second protrusion 85.

  Since the first protrusion 83 and the second protrusion 85 are provided, when the water supply tank 18 is inserted in the front-reverse direction, the second protrusion 85 of the upper lid 18a is moved to the first protrusion 85 of the partition wall 81. The water supply tank 18 cannot be inserted further into the projections 83. Therefore, before the water supply tank 18 is completely mounted on the water supply tank mounting table 82, the user can notice that the direction of the water supply tank 18 is reversed.

  On the other hand, if the water supply tank 18 is correctly inserted in the front-rear direction, the protrusion 86 formed narrower than the second protrusion 85 does not interfere with the first protrusion 83. Can be.

  The shape and length of the first projection 83 are designed such that when the water supply tank 18 is to be mounted in the front-reverse direction, the first projection 83 collides with the second projection 85 and the water supply tank 18 cannot be inserted any further. If so, there is no particular limitation.

  Note that the distance L from the front end of the partition shelf 25 to the front end of the first projection 83 is such that when the water supply tank 18 is inserted in the front-reverse direction, the rear part of the water supply tank 18 is separated by the partition 25. It is preferable that the length is set so that the door 11a of the refrigerator compartment 11 cannot be closed. This makes it easier for the user to notice that the water supply tank 18 is not correctly installed.

  Further, it is preferable that the distance L is such a length that the first projection 83 is located rearward of the installation position of the second projection 85 when the water supply tank 18 is correctly inserted into the front and rear. . Thus, when the water supply tank 18 is correctly inserted in the front-rear direction, the water supply tank 18 can be inserted all the way without interfering with the first protrusion 83.

  Further, it is preferable that the front end of the first projection 83 be located forward of the center of the storage space of the water supply tank. This makes it easier for the user to notice that the water supply tank 18 is not correctly installed.

  Further, the length of the first protrusion 83 in the front-rear direction prevents the second protrusion provided on the water supply tank 18 from advancing backward when the water supply tank 18 is inserted in a reverse direction. It is preferable that the length be as long as possible.

  In the present embodiment, an example in which the water supply tank 18 is placed on the partition shelf 25 is described, but in the present invention, the installation location of the water supply tank 18 is not limited to this. For example, the water supply tank 18 may be installed on the upper partition shelf 24 or beside the vegetable case 17a.

  Further, the first protrusion 83 may be disposed on the left side of the water supply tank 18 when viewed from the front side. That is, when this is applied to the configuration of the present embodiment, the first protrusion 83 may be provided on the inner wall side of the refrigerator compartment 11. However, considering the possibility of damage to the inner wall of the refrigerator compartment 11, the first projection 83 is preferably formed on the side wall of the partition wall 81.

  The above-described structure for preventing the water tank from being reversed is also included in the scope of the present invention. That is, the structure for preventing the water tank from being reversely mounted according to one aspect of the present invention includes a water tank and a water tank accommodating portion (for example, a water tank mounting table, a partition wall, or the like) that houses the water tank. The tank and the water supply tank housing are provided with a reverse attachment prevention mechanism for preventing the water supply tank from being mounted in a direction opposite to the correct installation position.

  In the above-described structure for preventing the water supply tank from being reversely mounted, the reversely mounting prevention mechanism may include a first protrusion provided on a partition wall that forms the water supply tank housing, and a front of an upper lid that forms the water supply tank. And a second projection provided on the second projection.

  Further, in the above-described structure for preventing the water tank from being reversely mounted, the reversely mounting prevention mechanism includes a projection provided on a water supply tank mounting table that forms the water supply tank housing, and a water storage part that forms the water supply tank. And a notch formed in the bottom surface of the rear end.

  According to the above configuration, before the water supply tank is completely mounted in the water supply tank housing, the user can notice that the water supply tank is in the opposite direction. Therefore, it is possible to prevent the water supply tank from being mounted in a direction opposite to the correct installation position.

<Second embodiment>
Subsequently, a second embodiment of the present invention will be described. In the second embodiment, the configuration for holding and fixing the partition shelf of the refrigerator 1 is different from that of the first embodiment. For other configurations, basically the same configuration as in the first embodiment can be applied. Thus, in the second embodiment, only points different from the first embodiment will be described.

  In the first embodiment described above, the partition shelf 24 is fixed to the heat insulating box 50 by using the holding member 32 for holding the partition shelf 24. However, in the present invention, the holding member does not necessarily have to be provided. Therefore, in the second embodiment, a configuration in which the partition shelf 24 is directly fixed to the heat insulating box 50 without using a holding member will be described.

  FIG. 10 shows a cross-sectional configuration of a rear part of the refrigerator compartment 11 at a position where the partition shelf 124 is attached in the refrigerator 1 according to the second embodiment. This figure corresponds to a cross-sectional view taken along the line XX of the refrigerator shown in FIG.

  In the second embodiment, the holding unit 132 for fixing the partition shelf 124 is integrated with the partition shelf 124. As shown in FIG. 10, the holding portion 132 is formed on the partition shelf 124 at a position facing the shower duct component 30 on the back surface thereof.

  The holding portion 132 has penetrating portions 136a and 136b protruding from the back surface of the holding portion 132. The penetrating portions 136a and 136b have a cylindrical shape, and hollow portions thereof are holes 133a and 133b for attaching screws.

  The holding member 32 is fixed to the heat insulating box 50 by two screws (fixing members) 171a and 171b. As shown in FIG. 5, the two screws 171a and 171b penetrate the shower duct component 30 and extend from the inner box 52 of the heat insulating box 50 to the heat insulating layer 53. In the present embodiment, when attaching the partition shelf 124 to the heat insulating box 50, screws can be attached from the screw attachment holes 133a and 133b formed in the partition shelf 124.

  As described above, in the refrigerator 1 according to the second embodiment, the holding portion 132 integrated with the partition shelf 124 and the screws 171a and 171b (fixing members) penetrate the cooling plate 31 and the shower duct component 30. And is fixed to the heat insulating box 50. According to this configuration, when the partition shelf 124 is pulled forward, the stress in the front-rear direction applied to the cooling plate 31 and the shower duct component 30 can be reduced.

  Further, as shown in FIG. 10, screws 171 a and 171 b for fixing the holding member 32 are arranged so as to penetrate the heat insulating material 70 a of the shower duct component 30. As described above, since the screws 171a and 171b are arranged so as to avoid the shower duct 30a, the cool air in the shower duct 30a is insulated through the holes in which the screws 171a and 171b and the screw are arranged. The possibility of flowing out to the box 50 side can be reduced.

<Third embodiment>
Subsequently, a third embodiment of the present invention will be described. The third embodiment is different from the first embodiment in the configuration for holding and fixing the partition shelf of the refrigerator 1. For other configurations, basically the same configuration as in the first embodiment can be applied. Thus, in the second embodiment, only points different from the first embodiment will be described.

  In the first embodiment described above, the partition shelf 24 is fixed to the heat insulating box 50 using screws as fixing members. However, in the present invention, the fixing member is not limited to the screw. Therefore, in the third embodiment, a configuration in which a partition shelf is fixed without using a screw will be described.

  FIG. 11 shows a cross-sectional configuration of a rear part of the refrigerator compartment 11 at a position where the partition shelf 224 is attached in the refrigerator 1 according to the third embodiment. This figure corresponds to a cross-sectional view taken along the line XX of the refrigerator shown in FIG.

  Similarly to the first embodiment, the partition shelf 224 in the third embodiment is fixed to the inner box 52 on the back side of the refrigerator compartment 11 via the holding member 32. Regarding the structure of the holding member 32, the same configuration as that described in the first embodiment can be applied.

  On the other hand, in the partition shelf 224, two claw members 271a and 271b are formed in a portion facing the shower duct constituent member 30 and the holding member 32 on the back surface. The claw members 271a and 271b protrude from the rear of the partition shelf 224. As shown in FIG. 11, the claw members 271a and 271b pass through the inner box 52 through the insides of the through portions 36a and 36b of the holding member 32, and reach the heat insulating layer 53.

  Thus, the partition shelf 224 is fixed to the heat-insulating box 50. That is, the claw members 271a and 271b function as fixing members.

  As described above, in the refrigerator 1 according to the third embodiment, the claw members 271a and 2171b (fixed members) integrated with the partition shelf 224 penetrate the cooling plate 31 and the shower duct component 30, and are insulated. It is fixed to the box 50. According to this configuration, when the partition shelf 224 is pulled forward, the stress in the front-rear direction applied to the cooling plate 31 and the shower duct component 30 can be reduced.

  As shown in FIG. 11, the claw members 271a and 2171b for fixing the holding member 32 are arranged so as to penetrate the heat insulating material 70a of the shower duct component 30. Further, a locking groove for locking the claw members 271a and 2171b is provided in the inner box 52 of the heat insulating box 50 to which the claw members 271a and 2171b are attached. Thereby, the claw members 271a and 2171b can be stably fixed to the inner box 52. As the locking groove formed in the inner box 52, for example, a push lock, a hook groove (a holder in which a claw member is locked), and the like can be given.

  In this manner, by disposing the claw members 271a and 2171b so as to avoid the shower duct 30a, the cool air in the shower duct 30a causes the claw members 271a and 2171b and the holes in which the claw members are arranged to be formed. It is possible to reduce the possibility of flowing out to the heat-insulating box 50 via the heat-insulating box 50.

<Fourth embodiment>
Subsequently, a fourth embodiment of the present invention will be described. The fourth embodiment differs from the first embodiment in the structure of the water supply tank and its surroundings. For other configurations, basically the same configuration as in the first embodiment can be applied. Thus, in the fourth embodiment, only differences from the first embodiment will be described.

  In the first embodiment described above, the water tank reverse attachment prevention mechanism is provided on the upper lid 18 a of the water tank 18 and the side wall of the partition wall 81. However, in the present invention, the attachment position of the reverse attachment prevention mechanism of the water supply tank can be appropriately changed. Therefore, in the fourth embodiment, a description will be given of a configuration in which the reverse attachment prevention mechanism of the water supply tank is provided in the water storage portion of the water supply tank and the water supply tank mounting table.

  FIG. 12A is a perspective view illustrating a configuration of a partition 325 provided in the refrigerator 1 according to the fourth embodiment of the present invention. FIG. 12B is a perspective view of a water supply tank 318 installed on the partition shelf 325 shown in FIG. FIG. 12B shows a state where the water supply tank 318 is viewed from the rear side.

  As shown in FIG. 12A, the outer shape of the partition shelf 325 is formed along the inner wall of the refrigerator compartment 11. Specifically, the partition shelf 325 has a shape in which the back surface portion facing the shower duct component 30 and the holding member 32 is hollow.

  In addition, a water supply tank mounting table 382 for mounting the water supply tank 318 is formed at the left end of the partition shelf 325 when viewed from the front. A partition wall 381 is provided between the water supply tank mounting table 382 and the shelf of the partition shelf 325 to partition them.

  Next, the structure of the water supply tank 318 will be described. As shown in FIG. 12B, the water supply tank 318 includes an upper lid 318a and a water storage section 318b as main components. The same material as in the first embodiment can be applied to the material of the upper lid 318a and the water storage portion 318b.

  A water supply pipe 384 connected to a water supply pump (not shown) installed on the back of the refrigerator compartment 11 is attached to the upper lid 318a. When the water supply tank 318 is correctly installed on the water supply tank mounting table 382, the water supply pipe 384 has a shape protruding toward the rear surface of the refrigerator compartment 11. The distal end of the water supply pipe 384 is connected to a water supply port of a water supply pump.

  In the refrigerator 1 according to the present embodiment, a projection 383 and a notch 385 are provided as a mechanism for preventing the water supply tank from being reversed. The protrusion 383 is formed so as to protrude from the surface of the water supply tank mounting table 382. The protrusion 383 has an elongated shape along the insertion direction of the water supply tank 318.

  The notch 385 is formed in the water storage part 318 b that constitutes the water supply tank 318. As shown in FIG. 12B, the notch 385 is formed by cutting out the bottom surface of the rear end of the water storage portion 318b.

  By forming such a notch 385, when the water supply tank 318 is mounted in the correct direction, the bottom of the water supply tank 318 may not contact the protrusion 383 formed on the water supply tank mounting table 382. Absent. That is, when the water supply tank 318 is installed at the normal position, the projection 383 is located below the cutout 385 so that they overlap when viewed from above.

  On the other hand, when the water supply tank 318 is inserted in a reverse direction, the bottom of the front surface 386 of the water supply tank 318 hits a protrusion 383 formed on the water supply tank mounting table 382, and the water supply tank 318 cannot be inserted further back. . Therefore, before the water supply tank 318 is completely mounted on the water supply tank mounting table 382, the user can notice that the orientation of the water supply tank 318 is reversed.

  In the present embodiment, a notch smaller than the notch 385 is formed on the front surface 386 side of the water supply tank 318. However, the notch on the front surface 386 side may not be formed. In addition, the notch 385 may have a shape in which a portion corresponding to the protrusion 383 of the water storage portion 318b (that is, only the right rear end portion of the water storage portion 318b) is recessed. Thereby, the decrease in the volume of the water storage portion 318b due to the cutout portion can be suppressed.

  In the configuration of the present embodiment, when a plastic resin is used as the material of the water storage portion 318b of the water supply tank 318, it is preferable to use a relatively soft material. Thereby, when the water supply tank 318 is erroneously inserted in the front-rear direction and the bottom portion (front surface 386) of the water storage portion 318b collides with the protrusion 383 of the water supply tank mounting table 382, the impact of the water storage portion 318b causes the water storage portion 318b. The possibility that the bottom portion of the 318b is damaged or damaged can be reduced.

<Fifth embodiment>
Subsequently, a fifth embodiment of the present invention will be described. The fifth embodiment is different from the first embodiment in the configuration for holding and fixing the partition shelf of the refrigerator 1. For other configurations, basically the same configuration as in the first embodiment can be applied. Therefore, in the fifth embodiment, only points different from the first embodiment will be described.

  In the first embodiment described above, the holding member and the screw (fixing member) are provided so as to penetrate the shower duct constituent member. However, the present invention is not limited to such a configuration. Therefore, in a fifth embodiment, a configuration example in which a partition shelf is attached to the back surface of the heat insulating box without penetrating the shower duct component will be described.

  FIG. 13 shows a cross-sectional configuration of the rear part of the refrigerator compartment 11 at the position where the partition shelf 24 is attached. This figure corresponds to a cross-sectional view taken along the line XX of the refrigerator shown in FIG. In FIG. 13, the illustration of the partition shelf 24 is omitted.

  In the fifth embodiment, the partition shelf 24 is fixed to the inner box 52 on the back side of the refrigerator compartment 11 via the holding member 432. The holding member 432 is disposed so as to straddle the shower duct component 30. The holding member 432 is fixed to the heat insulating box 50 by two screws (fixing members) 471a and 471b. As shown in FIG. 13, the two screws 471 a and 471 b are located at the left and right ends of the holding member 432, and are inserted into the heat insulating layer 53 from the inner box 52 of the heat insulating box 50. Thus, the holding member 432 is fixed to the heat insulating box 50.

  Although not shown, the holding member 432 is provided with a claw portion for holding a partition shelf, similarly to the holding member 32 provided in the refrigerator 1 according to the first embodiment. Then, the claws are engaged with the projections provided on the partition shelf 24 or the like, so that the partition shelf 24 can be fixed to the holding member 432. Thereby, the partition shelf 24 is disposed so as to straddle the shower duct component 30 with the holding member 432 interposed therebetween.

  As described above, in the refrigerator 1 according to the fifth embodiment, the two screws 471a and 471b are arranged on the left and right sides of the shower duct component 30 without penetrating the shower duct component 30. Such a configuration is also included in the scope of the present invention.

  According to the above configuration, the partition shelf 24 can be stably held in the refrigerator compartment 11. In addition, since there is no need to penetrate the shower duct component 30, the configuration of each component can be made simpler. Further, since the screws 471a and 471b can be arranged at a position farther from the shower duct 30a, the occurrence of dew condensation due to cooling of the screws can be further suppressed.

  The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims. Further, configurations obtained by combining the configurations of different embodiments described in this specification with each other are also included in the scope of the present invention.
