  In the present invention, the method for supplying ice making water in the water supply container 9 to the ice tray 7B is a time control method. As this method, there are a method in which a pump for supplying ice-making water is driven for a predetermined time and a method in which a solenoid is energized for a predetermined time to open the on-off valve. In the former method, ice making water is pumped from the water supply container 9 by a pump, and a predetermined amount of ice making water is supplied to the ice making tray 7B of the automatic ice making machine 7 by driving the pump for a predetermined time. In the latter method, as shown in the embodiment below, by energizing the solenoid 66 for a predetermined time and opening the on-off valve 61, the ice making water in the water supply container 9 is automatically dropped through the water supply channel 51A by the natural fall method. In this configuration, the ice making machine 7 supplies the ice tray 7B.

  The ice tray 7B is composed of 8 to 12 square ice pieces divided into a plurality of ice making chambers 7B1 such as four rows, two rows, six rows and two rows with the longitudinal direction as the row direction. Made of resin. The ice storage container 8 is made of a white, transparent, translucent or other color synthetic resin, and has a box shape with a top opening that is longer than the left and right widths. In the figure, the ice-making chambers 7B1 are divided into four in two rows, and are made of synthetic resin in which eight square ice pieces are made.

  At the upper end of the partition wall between each ice making chamber 7B1, a part of the partition wall is cut out to form a water passage 7B2. Thus, as described later, when ice-making water from the water supply channel 51A is supplied to a specific ice-making chamber 7B11 in the ice-making chamber 7B1, ice-making water that overflows the ice-making chamber 7B11 passes through the water passage 7B2 and is adjacent to the ice making chamber 7B11. It flows into the ice making chamber 7B1. In this way, the ice making water sequentially flows into the adjacent ice making chamber 7B1, and each ice making chamber 7B1 is filled with the ice making water. This supply of ice making water is time-controlled as described above.

  The water supply container 9 of the present invention is close to or substantially in close contact with the front, rear, left and right walls of the tank body 9A so as to close the upper surface opening of the tank body 9A having a rectangular upper surface opening that is longer than the width. A main tank container 9B having an upper surface opening is fitted into the upper part of the tank main body 9A, and an outward flange 9P formed at the upper end of the main tank container 9B is placed on the step part 9Q on the upper inner surface of the tank main body 9A. 9B is held in a state of floating in the tank body 9A, and the main tank container 9B is detachable from the tank body 9A. As a result, the main tank container 9B forms a main tank part, and an auxiliary tank part 9C whose upper surface is closed by the main tank container 9B is formed on the inner bottom part of the tank body 9A. As will be described later, the auxiliary tank portion 9C has a volume for storing ice-making water necessary for one to three ice-making operations, and is also a portion that supplies ice-making water for each time.

  In addition, the water supply container 9 is closed by a cover 9D in which the upper surface opening of the main tank container 9B is removable. The cover 9D is a combination in which a downward groove 9T formed in the peripheral edge of the lower surface is detachably fitted to the upper end of the tank body 9A, and the cover 9D is configured to be fastened to the tank body 9A by a detachable hook device 9R. The water supply container 9 includes an air passage 9E so as to supply air to the auxiliary tank portion 9C. This is because a recess 9E1 penetrating vertically is formed in the rear part of the main tank container 9B, and an air passage 9E is formed between the tank main body 9A and the main tank container 9B. A configuration in which a pipe penetrating the wall and communicating with the space above the main tank container 9B and the auxiliary tank portion 9C may be employed.

  A small-diameter supply hole 9H is formed in the bottom wall of the main tank container 9B in order to naturally supply ice making water in the main tank container 9B to the auxiliary tank portion 9C. With the upper surface opening of the main tank container 9B closed by a cover 9D having a water injection port 9K, the upper end opening of the air passage 9E communicates with the space above the main tank container 9B. The water inlet 9K is in a state of being closed by an openable / closable lid 9M which is a part of the cover 9D. Water can be injected into the main tank container 9B by pulling out the water supply container 9 from the refrigerator 1 and opening the lid 9M, but can also be performed by removing the cover 9D.

  When the cover 9D is attached to the tank main body 9A, the water supply container 9 is inserted into the small chamber 46 by sliding on the heat insulating partition wall 28, so that the water supply container 9 is fitted into the concave portion of the synthetic resin upper plate 29 and held at a predetermined position. The The predetermined position holding mechanism of the water supply container 9 is stable by adopting a configuration in which an elastic member slightly projecting upward from the synthetic resin upper plate 29 of the heat insulating partition wall 28 is engaged with an engaging part at the bottom of the water supply container 9. The elastic member is pushed downward by pulling the water supply container 9 forward against the elastic member, and the water supply container 9 can be pulled out from the small chamber 46.

  When the water supply container 9 is locked to the elastic member and held at a predetermined position, a switch (not shown) provided inside the back wall 32 of the refrigerator compartment 3 is turned on. Based on this, an ice making cycle described later can be started by the control circuit unit.

  The water supply container 9 has a circular water supply port 60 formed at the bottom of the auxiliary tank portion 9C at a position directly below the supply hole 9H on the bottom wall of the main tank container 9B, and is made of a synthetic resin that opens and closes the water supply port 60 by vertical movement. The on-off valve mechanism P provided with the on-off valve 61 is provided. The opening / closing valve 61 is formed with a valve portion 61A for opening / closing the supply hole 9H on the bottom wall of the main tank container 9B at the upper portion thereof, and the valve portion 61A is fitted in a conical spreading seat portion formed at the lower end of the supply hole 9H. Make a dome shape to fit. The on-off valve 61 is formed with a circular projecting portion that enters the water supply port 60 on the lower surface thereof, and an O-ring-shaped annular seal packing 64 is provided around the circular projecting portion. And the adhesion between the peripheral portion of the water supply port 60 are improved. In order to guide the up-and-down movement of the on-off valve 61, a plurality of guide pieces 95 are arranged at equal intervals around the on-off valve 61 from the bottom of the auxiliary tank portion 9C.

  The on-off valve 61 may be of a type that closes the water supply port 60 by its own weight, but if the closing function of the water supply port 60 is weak, a method of closing the water supply port 60 by lowering by the bias of the spring 67 may be used. . The spring 67 fits into a groove formed around the dome-shaped valve portion 61A and is held by the on-off valve 61.

  When the water supply container 9 is stored in the refrigerator 1, at a position directly below the water supply port 60, the heat insulating partition wall 28 is vertically penetrated in the vertical direction so as to open toward the upper surface of the ice tray 7 </ b> B. A water supply channel 51A in the vertical direction is formed. The lower end of the water supply channel 51A opens to a position facing one of the ice making chambers 7B1 on the rear side of the ice making tray 7B. The water supply channel 51 </ b> A has a circular cross section, and is formed by a water supply pipe 51 having an ice making water receiving portion 65 that extends in a funnel shape so that the ice receiving water flowing down from the water supply port 60 is good. The water supply pipe 51 is fixed to the through pipe portion 29A integrally formed with the synthetic resin upper plate 29 so as to penetrate the heat insulating partition wall 28.

  The on-off valve 61 is opened and closed by an operating member 90 with a permanent magnet 63 housed in the water supply channel 51A so as to be movable up and down. The permanent magnet 63 is arranged in a direction in which a pair of permanent magnets 63A and 63B spaced apart from each other repel each other, and as an example, the permanent magnets 63A and 63B are arranged with the S poles facing each other. Has been.

  A solenoid 66 is provided around the operating member 90 so as to correspond to the permanent magnets 63A and 63B. The solenoid 66 is held by the holder 93 and is fitted to the outside of the through pipe portion 29A so as to be positioned around the water supply channel 51A in a state of being housed in the recessed portion 30A of the synthetic resin lower plate 30 of the heat insulating partition wall 28. The holder 93 is fixed to the synthetic resin lower plate 30 with screws 94. The energization control to the solenoid 66 is performed in connection with the supply control of the ice making water to the automatic ice making machine 7 controlled by the control circuit unit provided in the refrigerator 1.

  As described later, when the operating member 90 rises and opens the on-off valve 61, the inner diameter of the water supply pipe 51 is formed so that a flow-down passage for ice-making water is formed between the periphery of the operating member 90 and the water supply pipe 51. The cross section having a smaller diameter has a circular outer shape, and the upper portion has an outer shape placed on the portion for receiving ice-making water 65 of the water supply channel 51A. Thus, the operation member 90 can be removed upward from the water supply channel 51A in a state where the water supply container 9 is removed from the refrigerator, so that the ice making water receiving portion 65 portion of the operation member 90 and the water supply channel 51A can be cleaned. It is. The upper end portion of the actuating member 90 forms a dome-shaped convex portion 90C that fits into a conical concave portion 61B formed on the lower surface of the on-off valve 61, and the convex portion 90C enters the concave portion 61B. The operation of pushing the on-off valve 61 upward and opening the on-off valve 61 becomes accurate.

  At the bottom of the main tank container 9B, a filter 92 is detachably held by a holding rib 91 formed in the main tank container 9B so as to cover the supply hole 9H of the main tank container 9B. The main tank container 9B is in a mounted state in which the outward flange 9P is locked to the step portion 9Q of the tank body 9A, and therefore can be removed from the tank body 9A by removing the cover 9D. For this reason, the inside of the tank main body 9A including the auxiliary tank portion 9C can be cleaned, and the filter 92 can be removed, so that the inner and outer surfaces of the main tank container 9B can be easily cleaned. Furthermore, since the on-off valve 61 can be removed, the inside of the water supply container 9 can be easily cleaned.

  FIG. 5 shows a state in which the solenoid 66 is not energized, the open / close valve 61 is lowered by the spring 67 and the water supply port 60 is closed. In this state, when the solenoid 66 is energized, an S pole is formed on the solenoid 66 and an N pole is formed on the bottom of the solenoid 66, and the operating member 90 is driven upward by the interaction with the permanent magnets 63A and 63B of the operating member 90. The on-off valve 61 is pushed upward by the member 90 to compress the spring 67 and the on-off valve 61 opens the water supply port 60. The on-off valve 61 opens the water supply port 60 and closes the supply hole 9H on the bottom wall of the upper main tank container 9B by the valve portion 61A.

  The ice making operation of the automatic ice making machine 7 includes an ice making process and a deicing process controlled by a control circuit unit provided in the refrigerator 1. When a sufficient amount of ice-making water is injected into the water supply container 9 and stored in a predetermined position of the refrigerator, the ice-making process starts when the ice-making start switch is turned on manually. 66 is energized for a predetermined time, the operating member 90 is raised, the on-off valve 61 opens the water supply port 60, and a predetermined amount of ice making water required for one ice making from the auxiliary tank portion 9C to the ice tray 7B automatically falls due to natural fall. Water is supplied. When the solenoid 66 is deenergized after being energized for a predetermined time, the on-off valve 61 is lowered so as to open the supply hole 9H and close the water supply port 60 as shown in FIG. An amount of ice-making water is supplied from the main tank container 9B to the auxiliary tank unit 9C by naturally dropping through the supply hole 9H.

  After the water supply to the ice tray 7B, ice is made by the control circuit unit, and when the non-contact sensor 200 described later detects the formation of ice in the ice tray 7B by the control circuit unit, the control circuit unit The deicing process is started, the electric mechanism 7A is started, the ice tray 7B is reversed and twisted, and the ice in the ice tray 7B is dropped into the lower ice storage container 8, and then the ice making chamber 7B1 faces the upper surface. The ice tray 7B is returned and water is supplied to the ice tray 7B again to enter the next ice making step and an ice making operation cycle is performed. The amount of ice in the ice storage container 8 includes an ice detecting lever 7C that descends from the dotted line position of FIG. 8 toward the solid line position by the electric mechanism 7A for each deicing process. The ice detecting lever 7C is arranged on the side of the ice tray 7B in the housing 101 so as not to obstruct the rotation of the ice tray 7B. When the amount of ice in the ice storage container 8 becomes full, the ice detecting lever 7C is restricted from descending by the ice, so this state is electrically detected and the ice making tray before entering the next ice making process. It is a mechanism to stop water supply to 7B.

  As described above, the automatic ice making machine 7 includes the electric mechanism 7A and the ice tray 7B that is rotationally driven by the electric mechanism 7A. An assembly of an electric mechanism 7A and an ice tray 7B that is rotationally driven by the electric mechanism 7A is configured to be removable by pulling it out of the refrigerator including automatic attachment / detachment of the power supply line to the electric mechanism 7A. The ice making machine 7 can be detached by pulling the electric mechanism 7A and the ice tray 7B together to the front of the refrigerator 1.

  In the automatic ice making machine 7, the electric mechanism 7A and the ice tray 7B are attached to the base member 100 in which the housing 101 surrounding the electric mechanism 7A and the ice tray 7B is formed, and the rear portion of the base member 100 is provided on the refrigerator main body 2 side. In this configuration, the connector 103 is detachably connected to the connector 102. In addition, the base member 100 has a lateral width that extends substantially across the width of the ice making chamber 6 and is disposed in contact with or close to the ceiling surface of the ice making chamber 6 along the ceiling surface of the ice making chamber 6. The left and right side portions 100A are placed on support portions 104 provided on the left and right side portions in the vicinity of the ceiling surface of the ice making chamber 6, and the base member 100 can be pulled out forward of the ice making chamber 6, and the base member 100 is It can be stored in the ice making chamber 6. With such a configuration, the automatic ice making machine 7 including the electric mechanism 7A and the ice tray 7B can be removed by being pulled forward of the refrigerator by the base member 100, and can be stored in the refrigerator.

  A specific configuration related to this will be described below. A portion 30A to which a partition plate 47 is attached is formed in the intermediate portion of the synthetic resin lower plate 30 of the heat insulating partition wall 28 constituting the ceiling wall of the ice making chamber 6 and the freezing chamber 5A, and the ceiling of the ice making chamber 6 on the left side thereof is formed. On both the left and right sides in the vicinity of the surface, there are formed support portions 104 on which the left and right portions 100A of the base member 100 are placed so as to be drawn out and stored in the front-rear direction. Specifically, a synthetic resin lower plate 30 is formed on the ceiling wall surface of the ice making chamber 6, and a support portion 104 is integrally formed on the synthetic resin lower plate 30. From the relationship of the molding method for injection molding integrally with the lower plate 30, the left and right portions 100 A of the base member 100 of the automatic ice making machine 7 are pulled out in the front-rear direction. It is a configuration that can be freely mounted. For this reason, the three support portions 104 on the left and right sides can also be referred to as rail portions 104. Moreover, the form formed in the rail shape extended continuously in the front-back direction may be sufficient as the support part 104. FIG.

  A connector 103 for supplying electric power to the electric mechanism 7A through the lead wire 103A is attached to a portion of the base member 100 beside the housing 101 that surrounds the ice tray 7B. The connector 102 on the refrigerator body 2 side is attached to the synthetic resin lower plate 30. In order for the automatic ice making machine 7 to be housed in the refrigerator 1, the left and right portions 100A of the base member 100 are placed on the support portion 104 and pushed in, so that the connector 103 is in a state where the automatic ice making machine 7 has reached a predetermined position in the refrigerator 1. Connected to the connector 102. In order to facilitate the pushing-in of the base member 100, the combination of the base member 100 and the support portion 104 is given a little flexibility, so that the connector 103 and the connector 102 are also a little flexible. Thus, the connector 103 and the connector 102 are smoothly coupled.

  As a specific configuration, the connector 102 is configured with a protruding pin, and the connector 103 is in the form of a hole into which the protruding pin is inserted. However, even if the base member 100 is slightly shifted up and down and left and right by pushing the base member 100, The entrance of the hole of the connector 103 is slightly widened so that the protruding pin of the connector 102 can easily enter the hole of the connector 103, and the recess 100F whose entrance side is widened so that the connector 102 enters with a margin. The connector 103 is attached to the back of the recess 100F. Further, the connector 103 has a flexible mounting structure so that it can move slightly in the vertical and horizontal directions. Thus, by sliding the base member 100 onto the support member in the ice making chamber 6, the connector 102 enters the recess 100F and is connected to the connector 103. Further, in order to pull out the automatic ice making machine 7 forward of the refrigerator, the connector 103 is automatically detached from the connector 102 as the base member 100 is pulled forward. An electric heater 130 is provided in the vicinity of the connector 102 in order to prevent the connector 102 and the connector 103 from freezing and becoming undetachable.

  In addition, a holding mechanism 160 that keeps the base member 100 in a state where it is stored in a predetermined position of the ice making chamber 6 is provided. Specifically, the ceiling wall 30 of the ice making chamber 6 is formed with a locking portion 152 that is recessed upward, and a shaft portion 154 is inserted and supported in the support hole 153 of the base member 100 on the front surface of the base member 100. A lock knob 155 is rotatably attached. The lock knob 155 has a protrusion 156 formed on a part of the outer periphery.

  In this configuration, the base member 100 to which the electric mechanism 7 </ b> A, the ice tray 7 </ b> B, and the lock knob 155 are attached is stored in a predetermined position in the ice making chamber 6 with the protruding portion 156 positioned downward. In this state, by rotating the lock knob 155 to position the protrusion 156 in the locking portion 152, the base member 100 can be held at a predetermined position in the ice making chamber 6. In this state, the base member 100 is in the ice making chamber. The base member 100 does not move to the front of the ice making chamber 6 and drop off due to vibration. The base member 100 can be pulled out to the front of the ice making chamber 6 by rotating the lock knob 155 and positioning the protruding portion 156 outside the locking portion 152.

  In order to effectively use the ice making chamber 6 having a limited capacity to increase the volume of the ice storage container 8 or to use the lower space of the ice storage container 8 as a storage space for frozen food as shown in FIG. The ice tray 7B is attached to a base member 100 that has a lateral width that extends across the width of the ice making chamber 6 and that is disposed in contact with or close to the ceiling wall surface of the ice making chamber 6. The left and right ends of the base member 100 are supported by support portions 104 provided near the ceiling walls of the left and right sides of the ice making chamber 6, and are provided close to the ceiling wall 30 of the ice making chamber 6. When the base member 100 is pulled out from the ice making chamber 6 and the ice making chamber 6 is used as a freezing chamber for storing frozen food, the support portion 104 is provided in the vicinity of the ceiling wall of the ice making chamber 6 so that the frozen food can be taken in and out. Does not get in the way. Further, the support portion 104 is located above the support rail 6A of the ice storage container 8 and has a configuration that does not interfere with the storage of the ice storage container 8 with respect to the refrigerator along the support rail 6A.

  On the upper surface of the base member 100, an upper cover 100D constituting a part of the base member 100 is attached to the base member 100 with screws 151 so as to cover the electric mechanism 7A portion, the lead wire 103A, and the connector 103. Finger cover portions 100B are recessed in the left and right side portions on the front side of the cover 100D. Further, on the lower surface of the base member 100, a handle portion 100C that is depressed so as to be another finger-hanging portion is formed at a position corresponding to the finger-hanging portion 100B. By pulling the base member 100 forward with the thumb hooked on the finger hook portion 100B and the other finger hooked on the handle portion 100C, the automatic ice making machine 7 can be easily pulled forward in the refrigerator. The base member 100 has an opening 100E at a position where ice-making water flowing down from the water supply pipe 51 is supplied to the ice tray 7B.

  An electric mechanism portion cover 101A that holds the electric mechanism 7A from the lower side and covers the lower side of the electric mechanism 7A is disposed below the electric mechanism 7A, and is fixed from the upper side of the base member 100 by fixing means 150 such as screws. The electric mechanism cover 101 </ b> A is attached to the base member 100. Thus, the electric mechanism 7A is supported by the base member 100 in a state where the lower side is supported by the electric mechanism portion cover 101A. Since the recess of the handle portion 100C is formed on the lower side of the base member 100 on the front side of the electric mechanism 7A, the electric mechanism portion cover 101A is formed in a shape along the recess, and the electric mechanism portion cover 101A is the handle portion. Although the upper surface and the rear surface, which are part of the recess of 100C, are formed, a form in which the entire recess of the handle portion 100C is formed may be used.

  The base member 100 is placed on the left and right support portions 104 of the ice making chamber 6 so that the automatic ice maker 7 can be removed by pulling it forward of the refrigerator. However, the ice tray 7B is provided with the base member 100 for easy cleaning. It can be easily removed from. As its structure, the drive side end of the ice tray 7B on the side of the electric mechanism 7A is provided with a drive side coupling portion 106 that is coupled to the rotation drive shaft 105 so as to rotate together with the rotation drive shaft 105 protruding from the electric mechanism 7A. In order to prevent the rotary drive shaft 105 from spinning around the drive side coupling portion 106, both are detachably fitted with a non-circular coupling structure.

  The driven end of the ice tray 7B opposite to the electric mechanism 7A side is provided with a protruding shaft 108 rotatably supported by a bearing portion 107 provided in the housing 101 portion of the synthetic resin base member 100. The shaft 108 is configured to be detachably combined with the bearing portion 107.

  The bearing portion 107 is press-fitted and held in the bearing hole 120 so as to form an upper bearing portion 109 formed above the bearing hole 120 formed in the housing 101 portion and a lower bearing portion 111 with respect to the upper bearing portion 109. The bearing member 110 on the driven side of the ice tray 7B is configured by the holding member 110.

  The holding member 110 has two ribs 115A extending forward in parallel from the circular flange on the rear surface, and protruding ribs 112A extending in the axial direction of the bearing portion 107 on the left and right outer surfaces of the rib 115A. 112B, and grooves 113A and 113B into which the protruding ribs 112A and 112B are fitted are formed on the frame-like portion 101 side. The rib 115A of the holding member 110 is formed with a slit 114A penetrating so that the upper portions of the protruding ribs 112A and 112B have flexibility, and an upper portion thereof forms an elastic portion 115A1 having elasticity. Protrusions 116A and 116B are formed on the outer surface of the elastic portion 115A1, respectively, and the height of the protrusions 116A and 116B is inclined at the insertion tip side to make it easier to insert the holding member 110 into the bearing hole 120. Shape. Further, the intermediate portion of the spring 118 is held by the protrusion 114B on one side surface of the holding member 110, the fixed end 118B of the spring 118 is inserted into the hole of the holding member 110, and the pressing end 118B of the spring 118 extends upward. .

  In such a configuration, the holding member 110 is prepared in a state where the pressing end 118B of the spring 118 is pushed and hooked below the protrusion 116A. In the horizontal state in which the ice making chamber 7B1 of the ice tray 7B faces the upper surface, the drive side of the ice tray 7B is coupled to the drive side coupling portion 106 so that the rotary drive shaft 105 is inserted. Then, with the protruding shaft 108 pressed against the upper bearing portion 109, the holding member 110 is inserted into the bearing hole 120 below the protruding shaft 108 from the opposite side of the ice tray 7B. Along with this insertion, the protrusions 116A and 116B are pushed by the side wall of the bearing hole 120 by pushing the left and right protruding ribs 112A and 112B into the bearing hole 120 in a state of fitting into the grooves 113A and 113B, and the elastic portion 115A1. As a result, the projections 116A and 116B enter the locking recesses 117A and 117B formed on the side wall of the bearing hole 120 by the restoring force of the elastic portion 115A1. Since the protrusions 116A and 116B have a shape in which the height of the insertion tip side (ice tray side) is low and inclined, the holding member 110 can be easily inserted into the bearing hole 120, and the protrusions 116A and 116B are inserted into the locking recesses 117A and 117B. Is easy to enter.

  With the projections 116A and 116B entering the locking recesses 117A and 117B, the pressing end 118B of the spring 118 is removed from the lower hook of the projection 116A, so that the spring 118 is restored to the bearing hole 120 by the restoring force. The pressing end 118B is locked inside the spring locking portion 119. By this locking, the holding member 110 is urged toward the ice tray 7B by the spring 118, and the ice tray 7B side end 110A of the holding member 110 presses the rear portion 7B2 of the ice tray 7B to drive the ice tray 7B. The rotation drive shaft 105 and the drive side coupling portion 106 are kept connected. In this state, on the driven side of the ice tray 7B, a lower bearing portion 111 is formed by the holding member 110 with respect to the upper bearing portion 109, and a cylindrical driven side bearing portion 107 that supports the protruding shaft 108 of the ice tray 7B. Is formed. Accordingly, the ice tray 7B can be rotated by the electric mechanism 7A.

  In this state, the protrusions 116A and 116B enter the locking recesses 117A and 117B at positions from the front of the locking recesses 117A and 117B.

  In order to remove the ice tray 7B from the housing 101 portion of the base member 100 in a state where the base member 100 is pulled out to the front of the refrigerator, the holding member 110 is pulled backward from the bearing hole 120 against the spring 118. The holding member 110 is released from the rear portion 7B2 of the ice tray 7B and the pressing force pushing the ice tray 7B forward is released, and the protrusions 116A, 116B are moved to a position approaching the rear ends of the locking recesses 117A, 117B. By pulling 110, the ice tray 7B can be moved backward. By this series of operations, the ice tray 7B is not held on the driven side, and the ice tray 7B can be moved rearward, so that the connection between the rotary drive shaft 105 and the drive side coupling portion 106 on the drive side of the ice tray 7B can be released. The ice tray 7B can be removed from the housing 101 portion of the base member 100. Accordingly, the ice tray 7B can be detached from the base member 100 while leaving the electric mechanism 7A on the base member 100, so that the ice tray 7B can be brought to a sink or the like and washed with water or the like.

  The reattachment of the ice tray 7B to the housing 101 portion of the base member 100 is performed according to the following procedure. That is, in the state where the holding member 110 is pulled backward from the bearing hole 120 against the spring 118, the rotation driving shaft 105 and the driving side coupling portion 106 on the driving side of the ice tray 7B are coupled, and the upper bearing portion 109 is coupled. By releasing the tension of the holding member 110 against the spring 118 with the protruding shaft 108 pressed against the spring 118, the holding member 110 is returned to the ice tray 7B by the spring 118 force, and the tip 110A of the holding member 110 is iced. Push the rear portion 7B2 of the pan 7B forward. For this reason, the coupling between the rotary drive shaft 105 and the drive side coupling portion 106 on the drive side of the ice tray 7B is maintained, and the lower bearing portion 111 with respect to the upper bearing portion 109 on the driven side of the ice tray 7B. A cylindrical driven-side bearing portion 107 that is formed by the holding member 110 and supports the protruding shaft 108 of the ice tray 7B is formed. As a result, the ice tray 7B can be rotated by the electric mechanism 7A.

  In the base member 100, since the ice tray 7B is inverted to approximately 180 °, the housing 101 portion formed so as to surround the ice tray 7B protrudes downward as compared to the right side portion thereof and enters the ice storage container 8. It becomes.

  In such a configuration, since the front wall formed with the handle of the ice storage container 8 at the upper end has a height that covers the front surface of the base member 100, the ice storage container 8 is moved forward while the base member 100 remains in the ice making chamber 6. When the base member 100 is pulled forward, the ice storage container 8 is removed from the ice making chamber 6, the lock knob 155 is rotated, and the protrusion 156 is positioned outside the locking portion 152. The member 100 can be pulled out to the front of the ice making chamber 6. In this case, as shown by the one-dot chain line in FIG. 6, the ice detecting lever 7C is set so that the standby position is located above the lower end of the housing 101, and the rear wall of the ice storage container 8 is not contacted with the housing 101 portion. By adopting a low configuration, there is no hindrance when the ice storage container 8 is pulled forward. Further, if the front wall of the ice storage container 8 is lowered to a height that does not contact the front wall of the ice storage container 8 even if the base member 100 is pulled forward, the base member 100 is left in the ice making chamber 6 while the ice storage container 8 remains. Can be pulled forward.

  The left and right end portions of the base member 100 are placed on the support portion 104. However, when the base member 100 is removed from the refrigerator, the base member 100 cooled at the temperature of the ice making chamber 6 is exposed to dew. appear. For this reason, when the base member 100 is stored again in the refrigerator, the dew freezes and the base member 100 and the support portion 104 stick together, and there is a possibility that the base member 100 cannot be pulled out again. In order to prevent this, the protrusion 126 that reduces the contact area between the left and right ends of the base member 100 and the support portion 104 is formed.

  In the present invention, an automatic ice making machine 7 including an electric mechanism 7A and an ice tray 7B that is rotationally driven by the electric mechanism 7A is detachably provided in the ice making chamber 6 in the refrigerator 1 in the front-rear direction. In the present invention, a non-contact type sensor 200 that detects the completion of ice making of the ice tray 7B is disposed on the upper wall 28 of the ice making chamber 6 at a position above the front-rear direction attaching / detaching path of the automatic ice making machine 7. is there.

  If this is described in the above configuration, the base member 100 is pulled out in the front-rear direction and stored in a substantially horizontal state with respect to the left and right support portions 104 of the ice making chamber 6. Thus, the automatic ice maker 7 is pulled forward, and the automatic ice maker 7 is stored in a predetermined position by pushing the base member 100. Since the non-contact type sensor 200 is arranged at a position above the front-rear direction attaching / detaching path of the automatic ice making machine 7, the non-contact type sensor 200 does not obstruct the attachment / detachment of the automatic ice making machine 7. Specifically, a recess 28P that is recessed upward is formed on the lower surface of the heat insulating partition wall 28 that is the upper wall of the ice making chamber 6, and the non-contact type sensor 200 does not protrude downward from the heat insulating partition wall 28. It is attached to 28P. The depression 28P can be formed continuously with the depression 30A.

  When the specified water supply amount is not supplied for some reason, or when the amount of water supplied to the ice tray 7 is controlled by time control, the amount of water stored in the water supply container 9 is less than the single specified water supply amount supplied to the ice tray 7. If the amount is too small, the ice tray 7 is less than the specified amount of water. In such a case, if the standby state is kept as it is, if a specified amount of water is supplied on the ice making operation in the next ice making operation, the ice making water overflows from the ice making tray 7B, and the water is stored in the lower ice storage container 8 or It falls into the ice making chamber 6 and freezes there, which is not preferable. For this reason, even when the ice tray 7 is less than the specified amount of water, it is desirable to return the ice tray 7B to a normal empty state by performing a predetermined ice making step and deicing step.

  Therefore, in the present invention, the positional relationship between the ice tray 7B and the water supply channel 51A is formed so that the ice making water from the water supply channel 51A is introduced into a specific ice making chamber 7B11 in the ice making chamber 7B1 of the ice tray 7B. Then, the non-contact type sensor 200 is arranged so as to detect the completion of ice making in the specific ice making chamber 7B11 where the ice making water is first introduced, and the ice making water stored in the specific ice making chamber 7B11 is frozen. By detecting with the sensor 200, the ice making end operation can be completed. Specifically, a recess 28P that is recessed upward is formed on the lower surface of the heat insulating partition wall 28 that is the upper wall of the ice making chamber 6, and the non-contact type sensor 200 does not protrude downward from the heat insulating partition wall 28. In 28P, it is attached obliquely downward and rearward so as to face the ice making chamber 7B11 through the opening 100E.

  In the above, an infrared sensor is a representative example of the non-contact type sensor 200. The structure is a thermistor A in which the electrical resistance changes by detecting infrared radiation energy related to the temperature emitted from the water and ice in the ice tray 7B, and a state concealed so as not to detect such infrared radiation energy. And the other thermistor B whose electric resistance is changed by detecting the ambient temperature, and the control circuit unit freezes the water in the ice tray 7B based on the voltage difference caused by the difference between the resistance values of both thermistors. It is possible to control to enter the de-icing process by determining that it has been performed.

  The temperature of each room of the refrigerator 1, various functions, various operation procedures, the operation state of the automatic ice maker 7 based on the detection by the non-contact type sensor 200, etc. are provided on the front surface of the refrigerator 1 by the control circuit unit, etc. Can be displayed on the display unit.

  In the present invention, as described above, the automatic ice making machine 7 is detachably provided in the ice making room 6 in the refrigerator 1 in the front-rear direction, so that the automatic ice making machine 7 and the ice storage container 8 are removed from the inside of the ice making room 6. Becomes wider and can be used as a storage room for frozen foods. In this case, when the stored frozen food is not in a predetermined frozen state, the operation is started in the forced operation mode when the refrigerant compressor 20 and the blower 25 of the refrigeration cycle are stopped. If it is, it is desirable to promote the freezing of the frozen food by continuing the operation state as the forced operation mode.

  Therefore, the present invention performs such control by detecting whether or not the stored frozen food is frozen by the non-contact sensor 200. In this case, a method can be adopted in which the compressor 20 and the blower 25 are set in the forced operation mode for a predetermined time after the non-contact sensor 200 detects a temperature at which the frozen food is not in a predetermined frozen state. Further, when the non-contact sensor 200 detects a temperature at which the frozen food is not in a predetermined frozen state, the compressor 20 and the blower 25 are operated in the forced operation mode, and the predetermined temperature at which the frozen food is frozen is detected. When this is detected, the forced operation mode of the compressor 20 and the blower 25 may be terminated.

  In addition, as described above, the automatic ice maker 7 is detachably provided in the ice making chamber 6 in the refrigerator 1 in the front-rear direction, so that frozen food is stored in the ice storage container 8 with the automatic ice maker 7 removed. You can In this case, when the stored frozen food is not in a predetermined frozen state, the compressor 20 and the blower 25 of the refrigerant in the refrigeration cycle are stopped and operated in the forced operation mode when the refrigerant is stopped. In some cases, it is desirable to promote the freezing of the frozen food by continuing the operation state as the forced operation mode.

  Therefore, the present invention performs such control by detecting whether or not the stored frozen food is frozen by the non-contact sensor 200. In this case, a method may be adopted in which the compressor 20 and the blower 25 are set in the forced operation mode for a predetermined time from when the non-contact sensor 200 detects a temperature at which the frozen food is not in a predetermined frozen state. When the non-contact type sensor 200 detects a temperature at which the food is not in a predetermined frozen state, the compressor 20 and the blower 25 are in the forced operation mode, and when the non-contact type sensor 200 detects the predetermined temperature at which the frozen food is frozen, The system which complete | finishes the forced operation mode of the compressor 20 and the air blower 25 may be sufficient.

  By detecting the temperature of the frozen food stored in the ice storage container 8 or the ice making chamber 6 by the non-contact sensor 200, the temperature can be displayed on the display unit provided on the front surface of the refrigerator 1 by the control circuit unit.

  In the above, the non-contact type sensor 200 detects the infrared radiation energy related to the temperature emitted from the frozen food stored in the ice storage container 8 or the ice making chamber 6 by the thermistor A, and the resistance of both thermistors A and B is detected. Based on the voltage difference caused by the difference in value, the control circuit unit determines that the frozen food is frozen, and performs control to end the forced operation mode and change display data displayed on the display unit. be able to.
