  Next, a basic structure and a cold air circulation structure of the refrigerator 1 called side-by-side will be described with reference to FIGS. FIG. 3 is a longitudinal sectional view of the first storage chamber 20 (freezer chamber). FIG. 4 is a longitudinal sectional view of the second storage chamber 30. FIG. 5 is a cross-sectional view of the vicinity of the blower fan 104.

  The freezer compartment door 21 will be described with reference to FIG. The freezer compartment door 21 has a structure in which the inside and outside of the freezer compartment door 21 are partially communicated. Specifically, the freezer compartment door 21 communicates between the inside and outside of the freezer compartment door 21 through the communication opening 23. The communication opening 23 opens obliquely with respect to the horizontal direction and the vertical direction. An ice supply device 40 is installed on the inner side of the communication opening 23. Further, a dispenser unit 10 is provided on the outer side of the communication opening 23.

  A machine room 12 is formed in the lower rear part of the main body of the refrigerator 1, and a compressor 11 is provided in the machine room 12. On the back side of the freezing room 20 which is the first storage room, a cooler 13 (arranged in the cooler room 16) for cooling the circulating air in the warehouse, and the cool air generated by the cooler 13 are stored in the storage room. A circulating fan 104 is provided for circulation. In the cooler 13, a compressor 11, a condenser (not shown), and a throttle (not shown) are sequentially connected by piping to form a refrigeration cycle. The blower fan 104 is disposed behind the ice making device 50. Since the ice making device 50 is disposed in front of the freezer compartment 20 in the depth direction in accordance with the position of the ice supply device 40, the space behind the ice making device 50 is likely to become a dead space that is difficult to use because the ice making device 50 becomes an obstacle. Therefore, the dead space can be effectively used by arranging the blower fan 104 in the space.

  The refrigerator 1 has a structure in which the blower fan 104 and the ice making device 50, the ice supply device 40, the dispenser unit 10, and the cooler chamber 16 are arranged so as to be displaced in the vertical direction. That is, the blower fan 104 and the ice making device 50 are arranged at the upper part in the height direction of the freezing room, the ice supply device 40 and the dispenser part 10 are arranged at the middle part in the height direction of the freezing room 20, and the cooler room 16 is the freezing room. It is arranged at the lower part of the height direction. And the freezer compartment duct 18a with small depth is located in the position corresponding to the ice supply apparatus 40 and the dispenser part 10. FIG. Therefore, the depth of the partition shelf 101 provided in the freezer compartment 20 can be increased. Moreover, the depth dimension of the partition shelf 101 is not greatly different depending on the height direction, and the inside arrangement is convenient.

  The machine room 12 is formed so as to project inside the first storage room 20 and the second storage room 30. And in the freezer compartment 20 shown in FIG. 3, according to the overhang | projection part 8 inside a store | warehouse | chamber, the cooler compartment 16 provided with the cooler 13 above that is formed. The cooler chamber 16 is partitioned by a partition wall surface 102 with the freezer compartment 20, and a defrosting heater 17 is disposed below the cooler 13. Further, the cooler chamber 16 is formed with a cool air return port 19 for taking the cool air of the freezer chamber 20 into the cooler chamber 16.

  Since the cooler 13 has a shape in which the depth in the cooler flow direction is suppressed and the depth dimension of the cooler is increased, the height of the cooler chamber 16 is the height at which the freezer compartment 28 is provided, Alternatively, the position can be set lower than the dispenser unit 10. During the defrosting operation of the cooler 13, the defrost heater 17 provided at the lower part of the cooler 13 is heated to defrost. During defrosting, heat leakage from the partition wall surface 102 to the freezer compartment 20 or outflow of heated air from the cold air return port 19 to the freezer compartment 20 may occur due to heater heating. In such a case, by setting the height of the cooler chamber 16 to be lower than the height at which the freezer compartment 28 is provided, the heated air slowly follows the outer periphery of the freezer compartment 28 according to the density difference of the air. Although it circulates, the influence on the partition shelf 101 provided above the freezer compartment 28 is small. In addition, since the freezer compartment 28 stores food inside the container, the influence of the temperature change of the air around the container can be reduced. On the other hand, the food stored on the partition shelf 101 is greatly affected by the temperature rise of the surrounding air. Accordingly, by setting the cooler chamber 16 and the freezer compartment 28 in the height direction to be substantially the same, or setting the cooler chamber 16 to be lower, the effect of the temperature rise on the food stored in the partition shelf 101. Can be reduced.

  A blower fan 104 is disposed above the freezer compartment 20 on the far side of the ice making device, and the blower fan 104 and the cooler compartment 16 are connected by a duct 18a provided on the far side of the freezer compartment. When the blower fan 104 is driven, the cold air generated in the cooler chamber 16 is taken into the blower fan 104 via the duct 18a and formed on the partition wall surface 102 with the freezer compartment 20 covering the front part of the blower fan 104. It is supplied into the freezer compartment 20 from the upper cold air outlet 103. Further, an ice making duct 105 is formed in the ice making device 50, and cold air is supplied to the ice making device 50, and the cold air that has passed through the ice making device 50 is discharged from the upper part of the freezer compartment 20.

  In FIG. 3, a freezer compartment outlet duct is formed on the back side of the freezer compartment 20 along with the duct 18a (not shown in the longitudinal sectional view of FIG. 3). This freezer compartment blowing duct guides the cool air of the blower fan 104 downward. In the freezer compartment outlet duct, a plurality of intermediate cold air outlets are formed in accordance with a plurality of partition shelves 101 that divide the freezer compartment 20 up and down, and the remainder of the cold air discharged to the upper cold air outlet 103 is the middle. It is supplied into the freezer compartment 20 from the cold air outlet. Then, the cold air supplied from the upper cold air outlet 103 and the plurality of intermediate cold air outlets flows from the upper side to the lower side in the freezer compartment 20, and then returned to the cooler chamber 16 from the cold air return port 19.

  Next, FIG. 4 is a longitudinal sectional view of the second storage chamber 30 (the refrigerator compartment 32 and the vegetable compartment 33). The cold air supplied to the refrigerator compartment 32 is supplied from a damper 7 provided in the upper part of the refrigerator compartment 32. The damper 7 is connected to the blower fan 104 via a connecting duct 9 (see FIG. 5) that penetrates the vertical partition wall 2. Therefore, when the damper 7 is opened, cold air is supplied from the blower fan 104, and this cold air is supplied into the refrigerator compartment 32 from the upper cold air outlet 203 provided in the partition wall 201 that covers the front portion of the damper 7. The damper 7 communicates with a refrigerator compartment duct 25 formed behind the refrigerator compartment 32. A plurality of intermediate cold air outlets 204 are formed in the cold room backside duct 25 in accordance with a partition shelf 202 that divides the cold room 32 up and down, and cold air is also refrigerated from the intermediate cold air outlets 204 by opening the damper 7. It is supplied into the chamber 32.

  Next, as shown in FIGS. 3 to 5, the cold air discharged from the blower fan 104 is supplied from the ice making device 50 (ice making discharge port 106), the second storage chamber (second storage chamber cold air supply port 203), and freezing. It is distributed to the chamber 20 (upper cold air outlet 103 and intermediate cold air outlet). Further, the cold air supplied to the ice making device 50 is discharged into the freezer compartment 20 in the lower part. In the refrigerator 1 of the present embodiment, the cold air discharged from the blower fan 104 is roughly divided into the ice making device 50, the refrigerator compartment 32, and the freezer compartment 20. Further, even when the cooling capacity is insufficient, since the blower fan 104 is disposed on the back side of the ice making device 50 and the ice supply device 40, the rotation capacity of the blower fan 104 is increased to increase the cooling capacity. However, due to the sound insulation effect provided by the ice making device 50 and the ice supply device 40 disposed in front of the blower fan 104, it is possible to prevent an increase in noise due to an increase in fan rotation speed. Even when air volume distribution is performed to increase the ice making capacity by increasing the amount of cool air supplied to the ice making device 50, the cold air that has passed through the ice making device 50 is then released from the upper part of the freezing room 20 into the freezing room 20. Also useful for improving cooling capacity.

  As shown in FIG. 4, the cold air supplied to the refrigerating chamber 32 flows from the upper side to the lower side of the refrigerating chamber 32, and is taken into the horizontal partition wall 4 constituting the bottom surface of the refrigerating chamber 32 from the cold air return port 23. . A part of the return duct 27 is formed inside the horizontal partition wall 4. The return duct 27 includes a horizontal return duct 26 a formed inside the horizontal partition wall 4, a vertical return duct 26 b formed vertically on the back side of the vegetable compartment 33, and the cooler compartment passing through the vertical partition wall 2. And a transverse return duct 26c for returning the cool air to 16.

  Next, the installation position of the door opening / closing detection switch will be described with reference to FIG. 6 is a cross-sectional view taken along the line AA in FIG. 7 is a cross-sectional view taken along line BB in FIG.

  In the present embodiment, a plurality of door opening / closing detection switches 37 are installed. In the present embodiment, the door opening / closing detection switch 37a is provided on the inside of the cabinet, and the door opening / closing detection switch 37b is provided on the freezer compartment door 21 side. The door open / close detection switches 37a and 37b are electrically connected in series to an operation circuit (not shown) of the ice supply device 40. Specifically, as shown in FIG. 6, the door opening / closing detection switch 37 a is provided on the side wall in the freezer compartment 20. The door open / close detection switch 37a is provided at the height of the ice supply device 40. The door open / close detection switch 37b is provided in the upper part of the freezer compartment door 21 or in the hinge cover 24. That is, the door open / close detection switch 37b is provided outside the freezer compartment 2 (outside of the refrigerator).

  The door open / close detection switches 37a and 37b are configured to cut off the energization when the plunger of the switch is pushed by the freezer compartment door 21 with the freezer compartment door 21 closed.

  The door open / close detection switch 37a inside the warehouse also manages lighting and extinguishing of an interior lamp (not shown). Therefore, it is necessary to operate according to opening and closing of the freezer compartment door 21 and is generally installed in the warehouse. However, it may be erroneously detected that the freezer compartment door 21 is closed due to malfunction. In this case, the ice supply device 40 is operated by operating the lever 15 with the freezer compartment door 21 opened.

  As shown in FIG. 7, the stirring member 121 and the crushing member 150 provided in the ice storage space 41 of the ice supply device 40 rotate during the ice discharging operation, and thus do not operate when the freezer compartment door 21 is open. It is necessary to.

  Therefore, the door opening / closing detection switch 37b on the freezer compartment door 21 side is electrically connected in series with the door opening / closing detection switch 37a on the inner side. That is, only when a plurality of door opening / closing detection switches 37 are connected in series to an electric circuit for driving the ice supply device 40 and the freezer compartment door 21 is detected to be closed by the plurality of door opening / closing detection switches 37. Then, the ice supply device 40 is driven.

  In other words, in the present embodiment, the ice supply device 40 does not operate even if the lever 15 is operated with the freezer compartment door 21 open unless both the door open / close detection switches 37a and 37b are broken. Thereby, safety can be ensured and reliability can be improved.

  Further, the user deliberately tried to erroneously detect that the freezer compartment door 21 was closed by pressing both plungers of the door open / close detection switch 37b on the freezer compartment door 21 side and the door open / close detection switch 37a on the inside of the refrigerator. In this case, the door opening / closing detection switches 37a and 37b on the freezer door 21 side and the inside of the refrigerator are installed at positions separated to a distance that cannot be operated with one hand. Therefore, the user cannot press the door open / close detection switches 37a and 37b at the same time. Thereby, since the ice supply apparatus 40 is not operated in the state in which the freezer compartment door 21 is opened, the reliability can be improved.

  In addition, the door open / close detection switch 37b on the freezer compartment door 21 side is installed at a position that is not inside the freezer compartment 20. Thereby, the malfunctioning by freezing can be prevented.

  Furthermore, a door open / close detection switch 37b on the freezer door 21 side is provided at a position in contact with the hinge cover 24a which is the uppermost part of the refrigerator 1. As a result, since the child is out of reach, it is possible to prevent mischief.

  Next, the installation position of the ice supply device 40 will be described. As shown in FIG. 2, the ice supply device 40 has an upper opening 42 disposed at a sufficiently high position from the floor on which the refrigerator 1 is installed. Specifically, in the present embodiment, the C dimension, which is the height from the floor surface to the upper opening 42, is about 1500 mm. Thereby, reliability can be improved as a structure where it is difficult for a child or the like to reach the inside of the ice supply device 40.

  Further, as shown in FIG. 7, the stirring member 121 disposed inside the ice supply device 40 is positioned below the upper opening 42 of the ice supply device 40. Specifically, in the present embodiment, the D dimension, which is the height from the upper opening 42 of the ice supply device 40 to the top of the stirring member 121, is about 80 mm. Thereby, reliability can be improved as a structure in which the user's fingers are difficult to reach inside the ice supply device 40.

  In addition, when the freezer compartment door 21 is closed, the inertial force associated with the operation of closing the freezer compartment door 21 acts on the ice in the ice supply device 40. And when the speed at which the freezer compartment door 21 closes is fast, the inertial force acting on the ice increases. Then, ice may jump out of the upper opening 42 of the ice supply device 40 into the freezer compartment 20. Therefore, in this embodiment, as shown in FIGS. 9A and 9B, the rod-shaped member 43 is installed inside the ice supply device 40 and above the stirring member 121. By providing the bar-shaped member 43, when the ice stored in the ice supply device 40 is about to jump out of the upper opening 42, it prevents the ice from contacting the bar-shaped member 43 and falling into the freezer compartment 20. Can do.

  Specifically, a part of the surface of the ice in the ice supply device 40 is melted and frozen again due to, for example, a temperature change caused by opening and closing of the freezer compartment door 21. At this time, the adjacent ice may be frozen while in contact with each other to form one ice block. The ice blocks are separated by the stirring operation of the stirring member 121.

  However, when the ice block grows, the stirring operation of the stirring member 121 merely lifts the ice block in the state of the ice block, and the ice block may not be separated.

  Therefore, the height position of the rod-shaped member 43 is the height position that is the upper end portion of the ice supply device 40 and separates the upper opening 42. Then, when the ice block is lifted upward by the stirring operation of the stirring member 121, the height is set to be in contact with the rod-shaped member 43. As a result, even if the ice block is strongly frozen, when the stirring member 121 performs the stirring operation, the ice block is pushed up and pressed against the rod-like member 43 to separate the ice. That is, the rod-shaped member 43 assists the operation of the stirring member 121.

  As described above, the safety structure that improves the reliability by preventing the ice made by the ice making device 50 from passing through and preventing the user from inadvertently inserting a finger into the ice supply device 40. can do.

  Moreover, the rod-shaped member 43 has a strength that can be used as a handle when the ice supply device 40 is attached to or detached from the freezer compartment door 21 or transported. That is, the rod-shaped member 43 may be provided at a substantially central position of the upper opening 42 in consideration of a weight balance when used as a handle.

  In the present embodiment, as shown in FIG. 6, an ice detecting lever 52 is used as a method for sensing the amount of ice stored in the ice supply device 40. Therefore, the bar-shaped member 43 is arranged avoiding the passing position of the ice detecting lever 52. Further, when a photoelectric element (not shown) is used, a rod-like member 43 may be arranged at the center of the ice supply device 40.

  The shape of the rod-shaped member 43 may be various shapes that can achieve the above effects, and may be, for example, a plate shape, a linear shape, or the like.

  Next, the removal structure of the ice supply device 40 will be described with reference to FIG. FIG. 10A shows a state where the ice supply device 40 is attached to the base member 200, and FIG. 10B shows a state where the ice supply device 40 is removed.

  As shown in FIGS. 10A and 10B, the ice supply device 40 is detachably attached to the base member 200 including the ice supply device detection switch 193. In a state where the ice supply device 40 is attached to the base member 200, a plunger (not shown) of the ice supply device detection switch 193 is pushed by the ice supply device 40 to form a closed circuit on the electric circuit, and the ice making device 50. Operates.

  Further, when the ice supply device 40 is detached from the base member 200, the plunger (not shown) of the ice supply device detection switch 193 is not pushed, so that an open circuit is formed on the electric circuit, so that the ice making device 50 operates. do not do.

  As described above, the refrigerator of the present embodiment can operate the ice supply device safely by preventing a user's erroneous operation and the like.

  The second embodiment will be described with reference to FIG. FIG. 8 is a perspective view showing a door opening / closing detection switch according to the second embodiment.

  As shown in FIG. 8, the plunger of the door opening / closing detection switch 38 is housed inside the freezer compartment door 21 and pushed by a convex portion provided on the hinge cover 24b. That is, the plunger of the door opening / closing detection switch 38 is operated by being pushed by the convex portion provided on the hinge cover 24 b by the closing operation of the freezer compartment door 21.

  Thereby, it becomes a structure in which a user cannot carelessly operate with fingers, and reliability can be improved by preventing the stirring member 121 and the crushing member 150 from operating while the freezer compartment door 21 is opened. In addition, a magnet switch etc. may be used for the door opening / closing detection switch 38 by the side of the freezer compartment 20, and it is good also as a structure which a user cannot operate with fingers.

  Moreover, it is good also as a structure which installs a switch in the inside of the hinge cover 24b on the ceiling surface of the refrigerator 1, provides a convex part in the freezer compartment door 21 located in the position facing a switch, and operates a switch by this convex part.
