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 on the rear side of the ice 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 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. 6 shows a state in which the solenoid 66 is not energized, the on-off valve 61 is lowered 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. This state is shown in FIG.

  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 opening / closing 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 a certain period of time has elapsed by the timer means of the control circuit unit, or the ice tray sensor detects the temperature at which the ice tray 7B has dropped. When detected, the deicing process is started by the control circuit unit, the electric mechanism 7A is started, the ice tray 7B is reversed and twisted, and the ice 124 in the ice tray 7B is dropped to the ice storage container 8 below. Then, the ice tray 7B is returned, water is supplied again, the ice making process is started, 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 7B before entering the next ice making process. It is a mechanism to stop water supply to

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 up and down and left and right. 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 unremovable.

  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 frozen food storage space 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 is disposed in contact with or close to the ceiling wall 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 projecting ribs 112A and 112B into the groove 113A and 113B in a state of being fitted into the grooves 113A and 113B. 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.

  When the ice tray 7B is reattached to the housing 101 portion of the base member 100 and the holding member 110 is pulled backward from the bearing hole 120 against the spring 118, the rotational drive shaft 105 on the drive side of the ice tray 7B By holding the projecting shaft 108 against the upper bearing portion 109 while performing the coupling with the driving side coupling portion 106, the holding member 110 is released by the force of the spring 118 by releasing the tension of the holding member 110 against the spring 118. Returning to the ice tray 7B, the front end 110A of the holding member 110 pushes the rear portion 7B2 of the ice tray 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.

  The amount of ice in the ice storage container 8 is detected by the ice detecting lever 7C that moves up and down by the electric mechanism 7A for each ice making process, and when detecting that the ice is full, the next ice making process is stopped.

  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. For this reason, in the ice storage container 8 immediately below the housing 101 part, the housing height from the bottom wall is limited by the housing 101 part as compared with the part in the ice storage container 8 on the right side, and the height is high. Not suitable for storing goods. For this reason, the partition plate 122 that partitions the inside of the ice storage container 8 left and right is detachably provided at a position substantially corresponding to the right end portion of the housing 101 portion.

  With the partition plate 122, the ice storage container 8 has an ice storage chamber in which the ice 124 falling from the ice tray 7 B can be stored in the left chamber immediately below the housing 101, and the right chamber has cup ice 123 having a height higher than the ice 124. It is possible to stack and store relatively tall articles such as. For this reason, as shown in FIG. 9, a large ice storage container 8 having a width close to the width of the ice making chamber 6 is provided for the purpose of expanding the space of the ice making chamber 6 below the ice storage container 8 and storing frozen food therein. When the ice storage container 8 is used as a large container having a large left and right volume for the purpose of accumulating a large amount of ice, or when the ice consumption is low, the inside of the ice storage container 8 is partitioned by the partition plate 122. As a result, the ice storage container 8 can be separated from ice storage, and a storage room for frozen food can be provided. The ice storage container 8 can be used effectively, and the frozen food can be easily arranged and taken out. Further, when the automatic ice making machine 7 is not used, by dividing the inside of the ice storage container 8 by the partition plate 122, the left and right chambers in the ice storage container 8 can be used as storage rooms for the frozen food. Easy to put in and out.

  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 1, 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. As shown by the dotted line in FIG. 8, 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 lowered so as not to contact the housing 101 portion. By adopting the configuration, there is no hindrance when the ice storage container 8 is 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 contact area between the left and right ends of the base member 100 and the support portion 104 is reduced. In the figure, protrusions 126 projecting sideways and downward are formed on the side and bottom surfaces of the left and right end portions of the base member 100, respectively, and the protrusions 126 are in contact with the support portion 104.

  Instead of this, a method of forming protrusions protruding toward the base member 100 on the upper surface and side surfaces of the support portion 104 corresponding to the left and right end portions of the base member 100 may be used. Also, as shown in FIG. Alternatively, the protrusion 126 may be formed on the upper surface of the base member 100 and the side surfaces of the left and right end portions of the base member 100 to reduce the contact area between the left and right end portions of the base member 100 and the support portion 104.

  By forming the protrusion 126 as described above, the drawing failure of the base member 100 due to the freezing of the base member 100 and the support portion 104 can be eliminated, and the drawing resistance of the base member 100 is reduced. It becomes easy to do.

  Further, the present invention provides a configuration that can be used for storing ice and storing other frozen articles by dividing the inside of the ice storage container 8. Therefore, a partition plate 122 is provided to divide the inside of the ice storage container 8 having a width approaching the left and right walls of the ice making chamber 6 into a portion directly below the ice tray 7B and a side portion thereof. Divide the part into separate article storage.

  Specifically, the base member 100 having a width that approaches the left and right walls of the ice making chamber 6 is inverted up to about 180 ° by the ice tray 7B. Therefore, the portion of the housing 101 formed so as to surround the ice tray 7B is It protrudes downward as compared with the right side portion and enters the ice storage container 8. For this reason, the inside of the ice storage container 8 immediately below the housing 101 is limited to a lower height than that of the right side ice storage container 8, and is not suitable for storing articles having a high height. Therefore, a partition plate 122 that partitions the inside of the ice storage container 8 to the left and right is detachably provided at a position substantially corresponding to the right side wall portion of the housing 101 portion. With this partition plate 122, the ice storage container 8 has an ice storage chamber 8 </ b> A in which the ice 124 falling from the ice tray 7 </ b> B can be stored in the left chamber immediately below the housing 101, and the right chamber 8 </ b> B has a cup higher in height than the ice 124. It is possible to stack and store other relatively tall articles such as ice 123.

  In such a configuration, the ice storage container 8 can be pulled forward while the base member 100 remains in the ice making chamber 6, and the base member 100 can be pulled forward while the ice storage container 8 remains in the ice making chamber 6. ing. For this reason, the front wall of the ice storage container 8 is lowered so as not to come into contact with the housing 101 portion, and even if one of the ice storage container 8 and the base member 100 is pulled forward, the other is not pulled out together with it. Constitute. Then, as shown by the dotted line in FIG. 8, the ice detecting lever 7 </ b> C is set so that the standby position is located above the lower end of the housing 101.

  In such a configuration, when the base member 100 is pulled forward to take out the automatic ice maker 7 to the front of the refrigerator, the right end portion of the housing 101 portion may remove the cup ice 123 or the like depending on how the cup ice 123 or the like is stacked. May push forward.

  In order to prevent this, a convex curved surface 125 is formed in the right corner portion at the front end of the housing 101 to allow other articles such as cup ice 123 stored in the right chamber 8B to escape sideways. The convex curved surface forms a relatively large convex curved surface (R surface) 125, and even if the convex curved surface (R surface) 125 hits the cup ice 123 or the like by the forward drawing of the base member 100, the cup ice 123 or the like is a convex curved surface. Since it slides along the (R surface) 125 and is pushed to the side and escapes away from the partition plate 122, the cup ice 123 and the like are not pushed forward.

  A relatively large inclined surface that is inclined from the front end toward the right chamber 8B can be formed at the right corner portion of the front end of the housing 101 so as to perform the same function. When the ice tray 7B is disposed on the right side of the ice making chamber 6, the partition plate 122 is arranged so that the ice storage container 8 has the ice storage chamber 8A on the right side and the storage chamber 8B for the article such as the cup ice 123 on the left side. Is provided.
