  First, the whole structure of a refrigerator is demonstrated. 1, 2, and 3, reference numeral 1 denotes a refrigerator body. The refrigerator main body 1 is divided into an inside and an outside by a heat insulating box body provided with a heat insulating material 4 (for example, a foam heat insulating material, a vacuum heat insulating material, etc.) between the outer box 2 and the inner box 3. A compressor 5 (not shown) that is a part of the refrigeration cycle is disposed at the lower rear of the refrigerator body 1. In addition, as long as the compressor 5 (not shown) is partitioned thermally from the storage room, the upper part back of the refrigerator main body 1 etc. may be sufficient and the installation position is not specifically limited.

  In the refrigerator body 1, there are formed a refrigerator compartment 6, an ice making compartment 14, an upper freezer compartment 7 a (not shown), a lower freezer compartment 7, and a vegetable compartment 8. The refrigeration cycle includes a compressor 5 (not shown), a condenser, a capillary tube, a cooler 18 and the like. The refrigerant compressed by the compressor 5 (not shown) is a condenser (not shown). )), Passes through a decompression section such as a capillary tube, evaporates in an evaporator (cooler described later), returns to the compressor 5 (not shown), and circulates so as to be compressed. Repeat this. Thereby, the inside of the previous refrigerator compartment 6, the lower freezer compartment 7, and the vegetable compartment 8 is cooled to predetermined temperature.

  At the front opening of the refrigerator body 1, a refrigerator compartment door 9 that opens and closes the refrigerator compartment 6, an ice making compartment door 10 that opens and closes the ice making compartment 14, a first freezer compartment door 11 that opens and closes the upper freezer compartment, and a lower freezer compartment 7 are opened and closed. The second freezer compartment door 12 and the vegetable compartment door 13 for opening and closing the vegetable compartment 8 are provided.

  Moreover, the refrigerator compartment door 9 is a double door type (French door) connected to the refrigerator main body 1 so that rotation is possible by the hinge 15 etc. which are shown in FIG. In addition, the refrigerator compartment door 9 also has a one-side opening / closing type (single door). The other doors are of a drawer type, and are configured such that when the door is pulled out, the storage container in each storage chamber is pulled out together with the door by a door frame and a rail.

  Reference numeral 16 denotes a cooler chamber. The cooler chamber 16 is configured to be partitioned by a freezer compartment back partition member 17 behind the lower freezer compartment 7. A cooler 18 constituting a part of the refrigeration cycle is disposed in the cooler chamber 16. A defrost heater 19 is disposed below the cooler 18 to remove frost attached to the cooler 18, and a blower 20 serves as a cool air circulation means. The blower 20 circulates the cold air exchanged by the cooler 18 to the refrigerator compartment 6, the ice making compartment 14, the upper freezer compartment 7 a (not shown), the lower freezer compartment 7, and the vegetable compartment 8. Reference numeral 21 denotes a damper that controls the amount of cold air blown from the blower 20 to each storage room and serves to control each storage room to a preset temperature.

  Reference numeral 22 denotes a heat insulating partition wall that separates the refrigerator compartment 6 from the freezing temperature zone (ice making chamber 14, upper freezing chamber 7a (not shown), lower freezing chamber 7), and 23 denotes the freezing temperature zone and vegetable room 8 It is the heat insulation partition wall which divides. That is, the refrigeration temperature zone chamber and the refrigeration temperature zone chamber having different temperature zones are adiabatically partitioned by the heat insulating partition walls 22 and 23, and the temperature zone has a common refrigeration temperature zone chamber (the ice making chamber 14 and the upper freezer compartment). 7a (not shown) and the lower freezer compartment 7) are configured such that the front is partitioned so as to receive the seal member of each door, and cool air can flow back and forth.

  Reference numeral 24 denotes a water storage tank provided in the refrigerator compartment 6. The water in the water storage tank 24 is supplied to an ice tray of an automatic ice maker described later by water supply means such as a pump.

  Reference numeral 25 denotes an automatic ice making machine. The automatic ice making machine 25 includes an electric mechanism 26 in an ice making frame 29, an ice tray 27 that is rotationally driven by the electric mechanism 26, and an ice detecting lever 28 that detects the amount of ice in an ice making chamber container 30 described later. Etc. are incorporated.

  The ice tray 27 is made of resin and has a long shape in the front-rear direction made of a material that can be twisted, and has four rows, two rows, five rows, or six rows in the longitudinal direction. Are divided into a plurality of cells.

  The ice detecting lever 28 is wide and has an L shape as shown in FIG. 2, and the tip of the ice detecting lever 28 moves in the direction of the arrow a around the fulcrum 28a by the driving force of the electric mechanism 26. Detect the amount of ice.

  As will be described later, the automatic ice making machine 25 has an ice detecting lever 28 on the left side (away from the blower 20) of the refrigerator main body 1 and a cold air passage for cooling the ice tray 27 on the right side of the refrigerator main body 1 (first cold air passage to be described later). 33) is provided. The ice making chamber container 30 is suspended from the door frame 10 a on the ice making chamber door 10 side, and is configured to be pulled out together with the ice making chamber door 10 when the ice making chamber door 10 is pulled out to the near side.

  The ice making frame 29 constituting the outer shell of the automatic ice making machine 25 is attached to the ice making chamber 14 in association with the partition member 17 as shown in FIGS. That is, the partition member 17 is arranged so as to take in the cold air blown out from the first cold air outlet 31 and the second cold air outlet 32 shown in FIG.

  The ice making frame 29 has a first cold air passage 33, a second cold air passage 34, and a third cold air passage 35, and cools the ice tray 27 and the ice detecting lever 28 and prevents frost formation.

  Specifically, as shown in FIG. 4, the first cold air outlet 31 and the second cold air outlet 32 are arranged on the partition member 17 side by side. The cold air blown out from the first cold air outlet 31 disposed near the center in the left-right direction of the refrigerator body 1 is guided to the first cold air passage 33 (see FIG. 5). The cold air blown out from the second cold air outlet 32 is guided to the second cold air passage 34 and the third cold air passage 35 (see FIGS. 3 and 5).

  The ice making control of the automatic ice making machine 25, the temperature control of the refrigerator compartment 6, the lower freezer compartment 7, the vegetable compartment 8, etc., and other various functions of the refrigerator are controlled by control devices provided in the refrigerator main body 1.

  Next, the cold air passage will be described in more detail. The cold air blown out by the second cold air outlet 32 shown in FIG. 4 is a second cold air passage 34 formed between the ice making frame 29 and the upper wall 14a of the ice making chamber 14 (see FIGS. 3 and 5). The ice detection lever storage chamber 36 is introduced into the third cold air passage 35 through an ice detection lever storage chamber opening 37 provided on the side wall 29d of the ice detection lever storage chamber forming the ice detection lever storage chamber 36. Is blown out. Thereby, the frost attached to the ice detecting lever 28 is sublimated with cold air, and the ice detecting lever 28 is prevented from being erroneously detected due to frost.

  That is, as shown in FIG. 2, the ice detecting lever 28 moves in the direction of arrow a before deicing, detects the amount of ice in the ice making chamber container 30, and uses the ice making tray 27 to convert the completed ice into the ice making chamber container 30. It is determined whether or not to drop it in. Here, when frost grows on the ice detecting lever 28, the detected height of the ice changes, and the accurate amount of ice cannot be measured. Therefore, the third cold air passage 35 is formed, and cold air is applied to the ice detecting lever 28 to sublime frost attached to the ice detecting lever 28 when the ice making chamber door 10 is opened and closed, for example.

  The electric mechanism unit 26 is located behind the ice tray 27 and in front of the partition member 17. It is necessary to consider the cold air from the first cold air passage 33 so that the electric mechanism portion 26 does not hinder the flow. Therefore, as shown in FIG. 3, the cold air blown out from the first cold air outlet 31 is the second cold air between the ice making frame 29 (the upper surface of the electric mechanism section 26) and the upper wall 14a of the ice making chamber 14. After passing through the passage 34, the air flows into the upper surface of the ice tray 27 in the ice tray storage chamber through a vent 29 b formed in the upper surface of the ice making frame 29.

  The first cold air passage 33 and the third cold air passage 35 are air passages provided on the ice making frame 29 side. Therefore, it reaches the front of the ice tray 27 (the side opposite to the electric mechanism portion 26 with the ice tray 27). On the other hand, the second cold air passage 34 is located above the ventilation hole 29 b, that is, from the electric mechanism portion 26 when viewed in the longitudinal direction of the ice tray 27.

  Next, an ice making frame 29 that houses the electric mechanism 26, the ice tray 27, etc. will be described with reference to FIG.

  In FIG. 5, 44 on the cold air passage 29a is a wind direction plate of the second cold air passage. The wind direction plate 44 of the second cold air passage is provided on the upstream side of the second cold air passage 34, and flows from the third cold air passage 35 to the cold air that flows to the vent hole 29 b side and is guided to the ice tray storage chamber. It has a function of distributing cold air led to the ice detecting lever storage chamber 36. The amount of cold air is distributed so that the ice tray storage chamber is larger than the ice detection lever storage chamber 36. Here, the overall configuration of the ice making frame 29 will be described. The ice making frame 29 is integrally formed by injection molding of resin. The ice making frame 29 has a gate shape with an open bottom surface, a first cold air passage 33 disposed on the side close to the blower 20, an ice detection lever storage chamber 36 disposed on the side far from the blower 20, An ice-making tray storage chamber is provided between the first cold air passage 33 and the ice detection lever storage chamber. The ice tray storage chamber 39 has an electric mechanism section storage chamber behind the ice tray storage chamber 39, and a drawer port for the ice tray 27 is formed in front of the ice tray storage chamber 39.

  The ice tray 27 slides back and forth in the ice tray storage chamber by means of a frame and a rail provided on the ice making frame 29 side. When the ice tray 27 is stored in the ice tray storage chamber, it is connected to the drive shaft 26a of the electric mechanism 26, and when the ice tray 27 is pulled out, the connection relationship with the drive shaft 26a is released.

  Further, the first cold air passage 33, the second cold air passage 34, and the third cold air passage 35 are provided between the upper wall 14 a and the ice making frame 29 when the ice making frame 29 is attached to the upper wall 14 a of the ice making chamber 14. Formed. The cold air blown out from the first cold air outlet 31 flows into the first cold air passage 33 and is stored in the ice tray by the wind direction plate 45 of the first cold air passage provided in the first cold air passage 33. The ice making tray storage chamber side wall 29c separating the chamber and the first cold air passage 33 is led to the ice making tray storage chamber opening and blown to the ice making tray 27.

  On the other hand, the cold air led from the second cold air outlet 32 to the second cold air passage 34 side flows by the airflow direction plate 44 of the second cold air passage and the third cold air passage 35 side. And flows into the ice tray storage chamber and the ice detection lever storage chamber 36, respectively.

  The arc-shaped portion 46 is configured so that the cold air entering the ice tray storage chamber through the ice tray storage chamber opening 43 formed in the ice tray storage chamber side wall 29c efficiently hits the surface (upper surface and side surfaces) of the ice tray 27. Lead. The electric mechanism unit 26 incorporated in the ice making frame 29 is made to ice from the ice making plate 27 by twisting the ice making plate 27. The temperature sensor 47 is a temperature detecting means for detecting whether ice is formed in the ice tray 27 and is attached near a cold air intake 48 provided near the end of the arc-shaped portion 46.

  The arc-shaped portion 46 is curved so as to approach the ice tray 27 from the upper surface of the ice making frame 29, and the cold air intake 48 is provided near the end of the arc-shaped portion 46 at a position close to the ice tray 27. As a result, the temperature detected by the temperature sensor 47 is close to the water temperature in the ice tray 27, and the ice making control is more accurate.

  The water in the ice tray 27 becomes ice when cooled for a predetermined time. The cold air temperature entering the temperature sensor 47 side from the cold air inlet 48 becomes lower as the water is cooled. Then, after this cold air temperature becomes, for example, −10 ° C. or less and a certain time has elapsed, it is judged by the control board that ice making is completed, and the ice tray 27 is rotated to perform the ice removing operation.

  Water supply, ice making, and ice removal in an automatic ice maker are performed as follows. A certain amount of water in the water storage tank 24 is supplied to the ice tray 27 by a pump (not shown) or the like. The temperature of the supplied water in the ice tray 27 is the same as that in the refrigerator compartment 6 immediately after the water supply, but is cooled by the cold air blown through the first cold air passage 33 and the second cold air passage 34, It becomes ice after a predetermined time. Meanwhile, the temperature sensor 47 detects the cold air temperature from the cold air inlet 48 and sends a signal to a control board (not shown).

  After a certain period of time has elapsed at the ice making temperature (temperature of change of state from water to ice), the control board operates the electric mechanism unit 26. When the electric mechanism unit 26 is operated, the ice detecting lever 28 is first operated to detect whether or not the ice making chamber container 30 is full of ice. If the ice making chamber container 30 is full of ice, the ice making tray 27 stands by without performing ice removal, but if it is not full, the ice making tray 27 is rotated from the ice making position to the ice removing position, and a twisting operation is performed. The ice in the ice tray 27 is dropped into the ice making chamber container 30.

  Thereafter, the ice tray 27 returns to the ice making position and receives ice from the water storage tank 24 to make ice again. By repeating this operation, ice is secured in the ice making chamber container 30.

  The frost that has grown on the ice detecting lever 28 when the ice making chamber door 10 is opened and closed is sublimated by the cold air blown into the ice detecting lever storage chamber 36 from the third cold air passage 35, and the ice detecting lever 28 has no frost. maintain.

  Hereinafter, the structure of the ice making chamber container 30 according to the present embodiment will be described with reference to FIGS. As shown in FIG. 6, the ice making chamber container 30 disposed below the ice making chamber 14 includes an ice storage section 30a that is an ice storage section for storing ice generated by the automatic ice making machine 25, and the ice storage section 30a. In addition, it has an accessory storage section 30b as a storage unit for storing items other than ice generated by an automatic ice making machine.

  In this way, by forming the ice storage part and the storage part separately in the ice making container 30, the ice making container produced by the automatic ice making machine can be produced only for the ice making container that has conventionally been produced by the automatic ice making machine 25. It is possible to store commercially available ice and small refrigerated foods.

  The ice storage compartment 30 a and the accessory storage compartment 30 b are partitioned into left and right compartments by a partition wall 30 c that extends upward from the bottom surface of the ice making chamber container 30 and extends in the front-rear direction of the ice making chamber container 30. In addition, since the partition 30c according to the present embodiment is integrally formed as the ice making chamber container 30 together with the ice storage compartment 30a and the accessory storage compartment 30b, not only the production efficiency is increased by omitting the assembly process, but also the ice making chamber container. There is an advantage that the rigidity of the entire 30 is increased.

  Further, in the present embodiment, a lid body 30 d that forms a top surface 30 d 1 higher than the upper end of the partition wall 30 c and covers the accessory storage section 30 b is attached to the ice making chamber container 30. The lid 30d can inform the user of the height of small items that can be stored in the small item storage section 30b. A rear wall 30b1 higher than the partition wall 30c on the ice storage compartment 30a side is formed on the rear side wall surface of the ice making chamber container 30 as shown in FIG. .

  The lid 30d is slidable in the horizontal direction with respect to the ice making chamber container 30. Even if the ice making chamber door 10 is closed with the lid 30d opened as shown in FIG. 8, the lid 30d is closed by abutting against the convex portion provided on the partition member 17. However, it is desirable that the lid 30d not be removed from the ice making chamber container 30. And, without removing the ice making room door 10 from the refrigerator main body 1, the ice making room container 30 can be taken out with the lid 30d attached.

  On the other hand, the lid bottom surface flange 30d4 formed at the lower edge of the lid 30d is restrained by the partition locking portion 30g formed at the upper end on the rear side of the partition 30c. It is possible to prevent the opening and opening. Further, a drop-off prevention stopper (not shown) is provided on the inner surface of the front side of the lid body 30d. When the lid body 30d is opened rearward more than a predetermined amount, it engages with a claw portion provided in the ice making chamber container 30. It is configured to match. For this reason, it is possible to prevent the lid body 30d from being opened excessively and falling backward from the ice making chamber container 30.

  Here, in the state where the ice making chamber door 10 is closed as shown in FIG. 7, the vertical projection of the automatic ice making machine 25 is located in the ice storage compartment 30a, and the vertical projection of the automatic ice making machine 25 corresponds to the accessory storage compartment 30b and the partition wall 30c. Are configured not to overlap. The upper end of the partition wall 30 c is lower than the lower end of the automatic ice maker 25, and the top surface of the lid 30 d is higher than the lower end of the automatic ice maker 25. Therefore, even a thing whose height cannot be stored in the area below the automatic ice making machine 25 can be stored in the accessory storage section 30b. Since the upper surface 30d2 on the front side of the lid 30d is formed higher than the upper surface on the rear side of the lid 30d, an operation for opening and closing the lid 30d is easy.

  FIG. 9 is a cross-sectional view of the ice making chamber container 30 as viewed from the front. The bottom surface of the ice storage compartment 30a has a curved shape with a deep center in the left-right direction, and the bottom surface of the accessory storage compartment 30b has a flat shape. Therefore, even if the ice tray 27 rotates and the ice falls into the ice storage compartment 30a, the ice does not pile up at the same position, and it is possible to draw the ice to the lower part near the center by the inclination of the bottom surface. . On the other hand, since the bottom surface of the accessory storage section 30b is flat, even when the ice making chamber door 10 is opened and closed, the ice cream or the like can be stored stably without falling down. The bottom surface of the ice storage section 30a is not limited to the shape where the center in the left-right direction is the deepest, but may have a shape where the position shifted from the center in the left-right direction becomes deep again. It is deeper towards. Moreover, although the bottom face of the accessory storage section 30b is planar, it is not limited to a complete plane, and those that are slightly curved at both ends in the left-right direction can be said to be substantially planar. Furthermore, even if the curved surface is smoother and has higher flatness than the curved surface of the ice storage compartment 30a, a certain degree of effect can be expected.

  Next, the cooling method in the accessory storage section 30b will be described. First, the ice tray 27 is cooled by the cold air flowing into the ice tray storage chamber from the vent hole 29b and ice making is performed. The cold air at this time flows out of the automatic ice making machine 25, contacts the lid body 30d and cools the lid body 30d, thereby indirectly cooling the inside of the small article storage section 30b. Thereby, it is not necessary to provide a vent hole for supplying cold air directly to the accessory storage section 30b separately from the automatic ice making machine 25, and it becomes possible to prevent a decrease in the amount of cold air discharged to the ice making tray 27 due to cold air distribution. Performance can be maintained. Further, by covering the accessory storage section 30b with the lid 30d, it is possible to prevent the air in the cooled accessory storage section 30b from escaping outside.

  FIG. 10 is a diagram illustrating a lid 30d according to the second embodiment. The lid 30d in the present embodiment is provided with a plurality of cold air introduction holes 30d3, and cold air can flow into the accessory storage section 30b from the cold air introduction holes 30d3. That is, the cold air that has passed through the automatic ice making machine 25 can be reused to cool the space in the lid 30d. The cold air introduction hole 30d3 is desirably provided on the rear side of the lid 30d in order to easily guide the cold air.

  FIG. 11 is a view showing an ice making chamber container 30 according to the third embodiment. The partition wall 30c in the present embodiment is provided with a plurality of cold air introduction holes 30e, and cold air can flow into the accessory storage compartment 30b from the cold air introduction holes 30e.

  FIG. 12 is a diagram illustrating a partition wall 30f according to the fourth embodiment. The partition wall 30f according to the present embodiment is detachably attached as a separate body from the ice making chamber container 30. Specifically, a concave portion (groove portion) is formed on the bottom surface or side surface of the ice making chamber container 30, and the bottom surface or side surface convex portion of the partition wall 30f is engaged with the concave portion. By separating the partition wall 30f as described above, it becomes easy to realize the ice making chamber container 30 having different width dimensions using the common partition wall 30f, and there is an advantage that versatility is enhanced. In addition, the unevenness | corrugation provided in the ice-making chamber container 30 and the partition 30f may mutually be reverse.

  Further, instead of providing the lid 30d, a guard extending downward is provided at the end of the automatic ice making machine 25 on the side of the small article storage section 30b, thereby preventing food or the like in the small article storage section 30b from flowing into the ice storage section 30a. You may do it.
