  In recent years, the demand for refrigerators having a larger capacity of the frozen storage space has increased. In response, refrigerators that use the entire lower part of the refrigerator as a refrigerated storage space are becoming popular. Among such refrigerators, in a refrigerator with a relatively narrow width, a configuration in which a vegetable room, which has been conventionally arranged at the lowest stage, is arranged as an isolation room in the upper refrigerator compartment has been studied.

  For example, when the above-described configuration is applied to the refrigerator 1 of Patent Document 1, two isolation rooms, a chilled room and a vegetable room, are arranged in two upper and lower stages in the lower part of the refrigerator compartment 2. Thereby, the partition plate for forming an isolation chamber is arrange | positioned to the upper part in a refrigerator compartment. Such a partition plate is heavier than the movable mounting shelf 45 disposed in the refrigeration space above the refrigeration chamber 2. Moreover, unlike the movable mounting shelf 45, such a partition plate is normally required to stably maintain a fixed state without being removed.

  However, if the partition plate is directly fixed to the resin inner box constituting the side surface in the refrigerator compartment 2 using screws or the like, the screws are exposed in the cabinet 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 are provided with a cooling plate on the back of the refrigerator compartment. For example, Patent Document 2 discloses a refrigerator 1 having a cooling plate 42 formed by processing a metal plate such as aluminum or stainless steel on the front surface of a cooling passage 29.

  Such a cooling plate is a thin plate-like 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, it aims at providing the refrigerator which can hold | maintain the partition plate arrange | positioned in a storage chamber more stably in this invention.

  A refrigerator according to one aspect of the present invention includes a storage room, a partition plate that partitions the storage room, a heat insulating box provided around the storage room, and a passage through which cool air passes, and the storage room And a fixing member for fixing the partition plate to the heat insulating box. And the said partition plate is being fixed with respect to the back surface of the said heat insulation box by the said fixing member, arrange | positioning so that the said channel | path component member may be straddled.

  In the refrigerator of the present invention, a holding member that holds the partition plate may be further provided between the partition plate and the passage component member, and the fixing member may be attached to the holding member.

  In the refrigerator of the present invention described above, 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 constituting member while avoiding the passage.

  In the refrigerator of the present invention, a plate-like member may be provided in the storage chamber so as to cover the passage constituting member.

  According to this invention, a partition plate can be fixed with respect to the back surface of a heat insulation box with a fixing member. Therefore, the partition plate arrange | positioned in the storage chamber of a refrigerator can be hold | maintained more stably. Thereby, the intensity | strength of a partition plate can be maintained.

  In this embodiment, let the surface in which the door is provided be the front surface of a refrigerator. And let the surface which opposes the front surface be a back surface. In addition, in this specification, when it is defined as “front side” or “back side”, the front or back side is provided on the basis of an arbitrary position, or from any position to the front or back side. It means direction. A direction from the front to the back or from the back to the front is referred to as the front-rear 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 insulation 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 the 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. Moreover, the inner box 52 forms the inner wall of each storage space (for example, the refrigerator compartment 11, the 1st freezer compartment 12, etc.). 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-shaped or plate-shaped heat insulating material. The foam heat insulating material can be formed of, for example, foamed polyurethane.

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

  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. Moreover, the partition shelf 25 is also attached to the inner wall of the refrigerator compartment 11 similarly to the partition shelf 24.

  As shown in FIG. 2, a chilled case 15 a is disposed between the partition shelf 24 and the partition shelf 25. The chilled case 15a and the partition shelf 24 form a chilled chamber 15. The partition shelf 24 constitutes the upper surface of the chilled chamber 15.

  Moreover, as shown in FIG. 2, the fruit case 16a and the vegetable case 17a are arrange | positioned below the partition shelf 25 equivalent to the bottom part of the refrigerator compartment 11 from the top. And the vegetable compartment 17 is formed by the fruit case 16a, the vegetable case 17a, and the divider 25. The partition shelf 25 constitutes the upper surface of the vegetable compartment 17. Further, above the vegetable compartment 17, a fruit case 16 comprising a fruit case 16a is provided.

  As described above, by providing the partition shelf 24 on the upper surface of the chilled chamber 15, the chilled chamber 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.

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

  In the refrigerator 1 according to this embodiment, a water supply tank 18 is disposed next to the chilled chamber 15. Water is stored in the water supply tank 18 and is used when ice making is performed in the ice making chamber 13 located at the lower stage. The water in the water supply tank 18 is supplied to an ice making machine 19 disposed above the ice making chamber 13. In addition, the place where the water supply tank 18 mentioned above is installed is an example, and is not limited to this in the present invention.

  Also, 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.

  A shower duct component 30 is disposed on the back side of the refrigerator compartment 11. Inside the shower duct constituent member (passage constituent member) 30, a shower duct 30a, which is a cool air passage, is provided. A plurality of outlets 46a, 46b, 46c, 46d, and 46e are formed in the shower duct constituent member (passage constituent member) 30 in the vertical direction. As will be described later, cold air from the evaporator 41 blows out into the refrigerating chamber 11 from the outlets 46a, 46b, 46c, 46d, and 46e.

  In the refrigerator compartment 11, the surface of the shower duct component 30 is covered with a cooling plate (plate 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-like member having a rectangular front shape, and is attached to the shower duct constituting member 30 so as to follow the surface shape of the shower duct constituting member 30. Since the cooling plate 31 is provided on the back surface of the refrigerator compartment 11, the stored items in the refrigerator compartment 11 can be radiatively cooled.

  In the refrigerator of the present invention, the cooling plate 31 may not be provided. In addition, the refrigerator of the present invention may be provided with a decorative plate whose surface is decorated instead of the cooling plate 31. Thereby, the aesthetics in the refrigerator compartment 11 can be improved. When using a decorative plate instead of the cooling plate, it is desirable to form the decorative plate with a material having a 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 the chilled case 15a forward and puts meat and dairy products into the chilled case 15a. In addition, the user pulls the fruit case 16a forward and puts the fruit into the fruit case 16a. The user pulls the vegetable case 17a forward and puts the vegetables into the vegetable case 17a.

  A cooling chamber 40 is disposed on the back side of the first freezer compartment 12 and the second freezer compartment 14. In the cooling chamber 40, the evaporator 41 which comprises a refrigerating cycle, the glass tube heater 61 for defrosting the evaporator 41, the cooling for sending the cool air from the evaporator 41 to the 2nd freezer compartment 14 grade | etc., Is carried out. A fan 43 is arranged. 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 cold air toward the refrigerator compartment 11 can be turned ON / OFF. A cooling fan 44 is provided above the damper 45 in the shower duct 30a. By operating the cooling fan 44, it is possible to send cold air into the refrigerator compartment 11 through the outlets 46a, 46b, 46c, 46d, and 46e.

  The cooling chamber 40 is formed with a plurality of outlets 47a, 47b, 47c, 47d in the vertical direction. From the outlets 47a, 47b, 47c, 47d, the cold air from the evaporator 41 blows out into the first freezer compartment 12, the ice making chamber 13, and the second freezer compartment 14.

  Next, the 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 through a refrigerant pipe through which refrigerant flows. The expander is composed of a capillary tube (capillary tube) and an expansion valve provided on the upstream side in the refrigerant flow direction with respect to the capillary tube. The compressor 42 is disposed in a machine room 60 provided on the back side of the bottom of the refrigerator 1.

  Further, 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 through a path of the compressor 42 → the condenser → the expander → the evaporator 41 → the compressor 42.

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

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

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

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

  More specifically, in the present embodiment, the cold air sent into the refrigerating room 11 moves downward from the back and top of the refrigerating room 11 along the front part of the refrigerating room 11, that is, the back of the door. Then, it passes through the front of the vegetable compartment 17 and under the vegetable compartment 17 and enters the return duct 49 from the return port 48.

The partition shelves 24 and 25 are fixed to the heat insulating box 50 by fixing members such as screws 71a and 71b.

  Further, a water supply tank mounting table 82 for mounting the water supply tank 18 is formed at the left end of the partition shelf 25 when viewed from the front. In addition, a partition wall 81 is provided between the water supply tank mounting table 82 and the shelf portion of the partition shelf 25 so as to partition the both.

  Next, the structure of the water supply tank 18 will be described. As shown in FIGS. 8 and 9, the water supply tank 18 includes an upper lid 18 a and a water storage portion 18 b as main components. In the present embodiment, both the upper lid 18a and the water storage portion 18b are made of plastic resin. For example, the upper lid 18a can be formed of a relatively flexible material such as polypropylene, and the water storage portion 18b can be formed of a relatively rigid material such as GPPS (general purpose polystyrene). 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 surface 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. And the front-end | tip of the water supply pipe 84 is connected to the water supply port of a water supply pump. The water supply pipe 84 is formed so as to protrude from a protrusion 86 formed on the upper lid 18 a of the water supply tank 18.

  By the way, in the refrigerator before this invention, it had the structure which can mount | wear with the water supply tank 18 in the reverse direction in the front-back direction. For this reason, the user often mistakenly installs the water supply tank 18 in the opposite direction. When the water supply tank 18 is mounted in the reverse direction, the water supply pipe 84 attached to the upper lid 18a is not connected to the water supply pump, which causes a problem that ice making cannot be performed.

  Therefore, in the refrigerator 1 according to the present embodiment, the first protrusion 83 is provided on the side wall of the partition wall 81, and the second protrusion 85 is provided on the upper lid 18 a of the water supply tank 18. These protrusions 83 and 85 function as an anti-reverse mechanism for the water supply tank.

  The first protrusion 83 is formed so as to protrude from the side surface of the partition wall 81 on the water tank mounting table 82 side. In the present embodiment, the first protrusion 83 is an elongated protrusion 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 lid 18 a along the shape of the front surface side of the water supply tank 18. For this reason, the user can easily pull out the water supply tank 18 by placing a finger or the like on the second protrusion 85. That is, the second projecting portion 85 also functions as a grip portion of 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 narrower than the second protrusion 85.

  By providing the first protrusion 83 and the second protrusion 85, when the water supply tank 18 is inserted in the reverse direction, the second protrusion 85 of the upper lid 18 a becomes the first protrusion of the partition wall 81. The water supply tank 18 cannot be inserted any further into the projection 83. Therefore, before the water supply tank 18 is completely attached to 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, when 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, so the water supply tank 18 is inserted deeply. Can do.

  The shape and length of the first protrusion 83 is designed so that when the water supply tank 18 is mounted in the reverse direction, the first protrusion 83 collides with the second protrusion 85 and the water supply tank 18 cannot be inserted any further. If it is, it will not be specifically limited.

  In addition, the distance L from the front side edge part of the partition shelf 25 to the front side edge part of the 1st projection part 83 is the rear part of the water supply tank 18 when the water supply tank 18 is inserted reversely in the front-back direction. It is preferable that the length is set such that the door 11a of the refrigerator compartment 11 cannot be closed. Thereby, a user becomes easy to notice because the water supply tank 18 is not installed correctly.

  In addition, the distance L is preferably set to such a length that the first protrusion 83 is positioned behind the installation position of the second protrusion 85 when the water supply tank 18 is inserted correctly back and forth. . Thereby, when the water supply tank 18 is correctly inserted in the front-rear direction, the water supply tank 18 can be inserted deeply without interfering with the first protrusion 83.

  Moreover, it is preferable that the front side edge part of the 1st projection part 83 is located ahead rather than the center part of the storage space of a water supply tank. Thereby, a user becomes easy to notice because the water supply tank 18 is not installed correctly.

  Further, the length in the front-rear direction of the first protrusion 83 prevents the rearward movement of the second protrusion provided on the water supply tank 18 side when the water supply tank 18 is inserted backward and forward. It is preferable that the length is long enough.

  In the present embodiment, an example in which the water supply tank 18 is placed on the partition shelf 25 is described. However, 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 24 or on the side of the vegetable case 17a.

  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 breakage of the inner wall of the refrigerator compartment 11, the first protrusion 83 is preferably formed on the side wall of the partition wall 81.

  The above-described structure for preventing reverse installation of a water supply tank is also included in the scope of the present invention. In other words, the structure for preventing reverse installation of a water supply tank according to one aspect of the present invention includes a water supply tank and a water supply tank storage part (for example, a water supply tank mounting table, a partition wall, etc.) for storing the water supply tank, The tank and the water supply tank housing are provided with a reverse prevention mechanism for preventing the water supply tank from being attached in the direction opposite to the correct installation position.

  Further, in the above-described structure for preventing the reverse attachment of the water supply tank, the reverse prevention mechanism includes a first protrusion provided on a partition wall constituting the water supply tank housing portion and a front of the upper lid constituting the water supply tank. And a second protrusion provided on the.

  Further, in the reverse supply prevention structure for the water tank, the reverse prevention mechanism includes: a protrusion provided on a water supply tank mounting table that constitutes the water supply tank storage part; and a water storage part that constitutes the water supply tank. You may comprise by the notch part formed in the bottom face part of a rear-end part.

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

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. In 3rd Embodiment, the structure which hold | maintains and fixes the partition shelf of the refrigerator 1 differs from 1st Embodiment. About the other structure, the same structure as 1st Embodiment is fundamentally applicable. Therefore, in the second embodiment, only points different from the first embodiment will be described.

  In 1st Embodiment mentioned above, the partition shelf 24 is being fixed with respect to the heat insulation box 50 using the screw as a fixing member. However, in the present invention, the fixing member is not limited to the screw. Therefore, in the third embodiment, a configuration for fixing the partition shelf without using screws will be described.

  FIG. 11 shows a cross-sectional configuration of the back portion 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 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. About the structure of the holding member 32, the structure similar to what was demonstrated in 1st Embodiment is applicable.

  In this way, the claw members 271a and 2171b are arranged so as to avoid the shower duct 30a, so that the cold air in the shower duct 30a can pass through the holes in which the claw members 271a and 2171b and the claw members are arranged. The possibility of flowing out toward the heat insulating box 50 can be reduced.

<Fourth Embodiment>
Subsequently, a fourth embodiment of the present invention will be described. In the fourth embodiment, the water supply tank and the surrounding structure are different from those of the first embodiment. About the other structure, the same structure as 1st Embodiment is fundamentally applicable. Therefore, in the fourth embodiment, only points different from the first embodiment will be described.

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

  Fig.12 (a) is a perspective view which shows the structure of the partition shelf 325 provided in the refrigerator 1 which concerns on the 4th Embodiment of this invention. FIG.12 (b) is a perspective view of the water supply tank 318 installed in the partition shelf 325 shown to Fig.12 (a). In addition, in FIG.12 (b), the state which looked at the water supply tank 318 from the back side is shown.

  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 a portion facing the shower duct constituent member 30 and the holding member 32 on the back surface portion is curled.

  Further, 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. Further, a partition wall 381 is provided between the water supply tank mounting table 382 and the shelf portion of the partition shelf 325 so as to partition the both.

  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 portion 318b as main components. The same material as that of 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 surface 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 that protrudes toward the back of the refrigerator compartment 11. And the front-end | tip of the water supply pipe 384 is connected to the water supply port of a water supply pump.

  In the refrigerator 1 according to the present embodiment, a protrusion 383 and a notch 385 are provided as an anti-reverse mechanism for the water supply tank. 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 cutout portion 385 is formed in the water storage portion 318 b that constitutes the water supply tank 318. As shown in FIG. 12B, the notch 385 is formed by notching the bottom surface portion of the rear end portion of the water accommodating 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 hits 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 protrusion 383 is positioned below the notch 385 so that they overlap each other when viewed from above.

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

  In the present embodiment, a cutout smaller than the cutout portion 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. Moreover, the notch 385 is good also as a shape where the part (namely, only the right side rear-end part of the water accommodating part 318b) corresponding to the projection part 383 of the water accommodating part 318b was dented. Thereby, the reduction | decrease of the volume of the water accommodating part 318b by a notch part can be suppressed.

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

<Fifth Embodiment>
