JP-A-11-132614

  In recent years, there has been a demand for an ice manufacturing storage device having a structure in which ice manufactured in an ice making chamber is stored in an ice storage chamber different from the ice making chamber. The ice body and ice storage room are usually separated by the door body, and when moving ice from the ice making room to the ice storage room, the door body is displaced to connect the ice making room and ice storage room. I will let you.

  In this type of ice manufacturing and storage device, if the amount of ice stored in the ice storage room can be detected, the ice from the ice machine installed in the ice making room and the ice from the ice making room to the ice storage room are automatically removed. Convenient to do. However, in the conventional ice detection system, since ice detection fins are provided in the ice tray, it is impossible to detect the amount of ice stored in an ice storage chamber provided separately from the ice making chamber.

  In view of the above problems, even when the ice storage chamber is configured separately from the ice making chamber, an ice manufacturing storage device, a refrigerator, and ice that can detect the amount of ice stored in the ice storage chamber with a simple configuration An object of the present invention is to provide a method for controlling a production storage device.

  In order to solve the above-mentioned problems, in the present invention, an ice making and storage device having an ice making chamber provided with an ice making machine and an ice storage chamber communicating with the ice making chamber is arranged between the ice making chamber and the ice storage chamber. A state in which the ice making chamber and the ice storage chamber are partitioned by the door body, and the ice making chamber and the ice storage chamber communicate with each other by displacing the door body toward the ice storage chamber. A door body driving device for switching, and a detector that detects the amount of ice in the ice storage chamber based on whether the door body interferes with ice in the ice storage chamber when the door body is displaced toward the ice storage chamber side. It is characterized by that.

  In the present invention, since the door body is disposed between the ice making chamber and the ice storage chamber, the ice making chamber and the ice storage chamber are usually partitioned by the door body. Can be held in. Further, when the ice is moved from the ice making chamber to the ice storage chamber, the door body is displaced by the door body driving device, so that the ice making chamber and the ice storage chamber are in communication with each other. Here, when the ice making chamber and the ice storage chamber are communicated with each other, in the present invention, the door body is displaced toward the ice storage chamber. Therefore, even when the amount of ice in the ice storage chamber is detected, the door body is displaced toward the ice storage chamber. Is used. That is, when the door body is displaced toward the ice storage chamber, the door body and ice will not interfere if the ice volume in the ice storage chamber is small, and the door body will interfere with ice if the ice volume in the ice storage chamber is large. become. Therefore, the amount of ice in the ice storage chamber can be detected by detecting whether or not the door and ice interfere with the detector.

  In this invention, it is preferable that the said door body drive device makes the said ice-making chamber and the said ice storage chamber communicate by rotating the said door body to the said ice storage chamber side centering on the base end side. If comprised in this way, the door body drive device of a simple structure can be driven.

  In this invention, it is preferable that the said ice storage chamber exists in the downward position of the said ice making chamber. If comprised in this way, the ice removed from the ice maker in the ice making chamber can be moved to an ice storage chamber by dead weight.

  In the present invention, in the case where a partition wall having an opening that is opened and closed by the door body is provided between the ice making chamber and the ice storage chamber, the door body is an elastic body at a portion that abuts on the partition wall side. Preferably it comprises a layer. If comprised in this way, since an elastic body layer functions as a sealing material, an ice making room and an ice storage room can be completely isolated by a door.

  In this invention, when the said ice storage chamber exists in the downward position of the said ice making chamber, it is preferable that the said door body is provided with the elastic body layer in the substantially whole surface of the said ice making chamber side. If comprised in this way, since the ice removed from the ice maker in the ice making room can be received by the elastic body layer of the door, the falling sound of ice can be reduced.

  In the present invention, the door body includes a door main body for partitioning the ice making chamber and the ice storage chamber, and an ice detecting portion protruding from the door main body to at least one of a front end side and the ice storage chamber side. It is preferable. With this configuration, the door body can be divided into a shape suitable for communicating the ice making chamber and the ice storage chamber, and only the ice detecting portion can be configured to be suitable for detecting ice. That's fine.

  In the present invention, when the door body driving device rotates the door body toward the ice storage chamber side around its base end side, the ice making chamber and the ice storage chamber communicate with each other. Is preferably arranged at a substantially central position in a direction in which the rotation center axis of the door body extends in the door body. With this configuration, even when the ice storage is piled up in the ice storage chamber, the ice detection unit will interfere with the top of the ice or the vicinity thereof, so the ice may be newly moved to the ice storage chamber. It is possible to reliably detect whether or not.

  In this invention, it is preferable that the said ice detection part consists of a thin plate which orient | assigned the in-plane direction to the moving direction of the ice from the said ice making chamber to the said ice storage chamber. With this configuration, when the ice making chamber and the ice storage chamber are communicated to move the ice from the ice making chamber to the ice storage chamber, the ice detecting section does not get in the way even though the ice moves.

  In the present invention, when the ice detecting unit is fixed to the door body, the detector monitors the attitude of the door body, and when the door body is displaced to the ice storage chamber side, the ice detecting unit Adopting a configuration that detects that a predetermined amount or more of ice is stored in the ice storage chamber when the door body is prevented from being displaced toward the ice storage chamber due to interference with ice in the ice storage chamber. Can do.

  In the present invention, when the ice detecting section is supported by the door body so as to be displaceable, the detector monitors the ice detecting section, and when the door body is displaced to the ice storage chamber side, the detection is performed. A configuration may be adopted in which when the ice part interferes with the ice in the ice storage chamber and is displaced with respect to the door body, it is detected that a predetermined amount or more of ice is stored in the ice storage chamber.

  The ice production storage device to which the present invention is applied is mounted on a refrigerator, for example.

  In the present invention, an ice making chamber provided with an ice making machine, an ice storage chamber communicating with the ice making chamber, a state where the ice making chamber and the ice storage chamber are partitioned, and a state where the ice making chamber and the ice storage chamber are communicated In a control method of an ice manufacturing and storage apparatus having a door body to be switched, when the door body is displaced toward the ice storage chamber so that the ice making chamber and the ice storage chamber are in communication with each other, the door body is the ice storage chamber. When it detects whether or not it has interfered with the ice in the room and obtained a detection result that the door body does not interfere with the ice in the ice storage room, it moves the ice from the ice making machine to the ice storage room. The movement of ice from the ice making machine to the ice storage chamber is stopped when a detection result is obtained that the door body has interfered with ice in the ice storage chamber.

  In the present invention, since the amount of ice in the ice storage chamber can be detected by the same operation as moving the door body when moving ice from the ice making chamber to the ice storage chamber, the ice storage chamber is configured separately from the ice making chamber. Even if it is, the amount of ice stored in the ice storage chamber can be detected with a simple configuration.

  Below, with reference to drawings, an example of the automatic ice manufacture and storage apparatus mounted in the refrigerator to which this invention is applied is demonstrated.

(Overall structure)
FIG. 1 is an explanatory view schematically showing a longitudinal section of an ice manufacturing and storage apparatus to which the present invention is applied. In FIG. 1, an ice manufacturing and storage device 1 according to the present embodiment is a device that manufactures and stores ice in a refrigerator, and is adjacent to an ice making chamber 2 having an ice tray 21 and a position below the ice making chamber 2. A partition wall 9 having an opening 90 through which ice passes is formed between the ice making chamber 2 and the ice storage chamber 3. In the ice making chamber 2, both ends of the ice making tray 21 are supported by the rotating shaft 23 of the rotating mechanism 22, and the ice in the ice making tray 21 is inverted by the rotating mechanism 22, and then the ice making tray 21. It is automatically dropped from the ice tray 21 by being heated by a built-in heater (not shown). In the ice manufacturing and storage device 1, for example, the ice making chamber 2 is disposed in a refrigerator compartment of a refrigerator, and the ice storage chamber 3 is disposed in a freezer.

(Configuration of door opening / closing unit)
2A, 2B, and 2C are a front view, a plan view, and a right side view of a door opening / closing unit used in an ice manufacturing and storage apparatus to which the present invention is applied. As shown in FIGS. 1 and 2 (A), (B), and (C), in this embodiment, a door opening / closing unit 10 for opening and closing the opening 90 is configured with respect to the opening 90 of the partition wall 9. Has been. The door opening / closing unit 10 has a rectangular frame 11 fixed to the partition wall 9 along the opening 90, and the frame 11 constitutes a part of the partition wall together with the partition wall 9. Further, the door opening / closing unit 10 rotates the door body 4 around the base end side of the door body 4 that can open and close the opening 110 that overlaps the opening 90 of the partition wall 9 in the frame 11, and opens the door. When the body 4 closes the opening 110 of the frame 11 (the opening 90 of the partition wall 9), and the door body 4 is rotated to the ice storage chamber 3 side, the ice making chamber 2 and the ice storage chamber 3 are connected to the openings 110, 90. And a door drive unit 7 that communicates with each other.

  Here, the door body 4 includes a door main body 5 having a rectangular planar shape capable of closing the opening 110 of the frame 11 and a lever ice detecting unit 6 described later. The door main body 5 includes the opening 110. And a rubber elastic sheet 53 laminated on the entire upper surface of the plate 52 that contacts the frame 11. Therefore, when the door body 5 is in contact with the frame 11, the ice making chamber 2 and the ice storage chamber 3 are completely sealed by the elastic sheet 53.

  The door body 4 is supported so that the base end side of the plate 52 can rotate with respect to the side plate portion 111 of the frame 11 via a support shaft 55, while the door body drive device 7 projects coaxially with the support shaft 55. The output shaft 73 is connected. For this reason, when the output shaft 73 rotates, the door body 4 rotates around the axis of the output shaft 73 and the support shaft 55 on the base end side.

  In the present embodiment, the lower surface of the door main body 5 is configured so that the amount of ice stored in the ice storage chamber 3 can be reliably detected by rotating the door body 4 toward the ice storage chamber 3 by the door body driving device 7. The lever-shaped ice detecting section 6 is fixed. Here, the lever-shaped ice detecting unit 6 is fixed to the lower surface of the door main body 5 at a central position in the rotation center axis direction (width direction) of the door body 4. The lever-shaped ice detecting section 6 is made of a thin plate and is fixed to the ice from the ice making chamber 2 to the ice storage chamber 3 with the in-plane direction in the moving direction. The lever-shaped ice detecting portion 6 has a substantially triangular shape on the tip side, and the two apexes 61 and 62 of the triangle portion are in a state of projecting toward the lower side and the tip side of the door body 5 respectively.

(Detailed configuration of door drive unit)
3A and 3B are a longitudinal sectional view and a transverse sectional view of a drive unit used in an ice manufacturing and storage apparatus to which the present invention is applied. FIG. 4 is an enlarged view of a portion D in FIG.

  As shown in FIGS. 3 (A) and 3 (B), the housing of the door body driving device 7 is constituted by two cases 74 and 75, and a motor 71 and a reduction wheel train 70 are provided inside the cases 74 and 75. It is stored.

  The motor 71 is a stepping motor, and includes a stator having a ring coil and a pair of stator cores arranged on both sides in the radial direction of the coil, and a rotor arranged inside the stator. The reduction gear train 70 is composed of a plurality of external gears 701, 702, 703, 704, 705, and 706, and after rotation is transmitted to the output shaft 73 via the external gear 706, the output shaft 73 is Thus, the rotation is transmitted to the door body 4 described with reference to FIGS. 1 and 2. As a result, the door body 4 is switched between a flat posture shown by a solid line in FIG. 2C and a posture inclined 45 ° obliquely downward shown by a one-dot chain line.

  As shown in FIG. 4, the output shaft 73 includes a sensor 8 that monitors the posture of the door body 4 based on the rotational position of the output shaft 73, and the sensor 8 is a side surface of the output shaft 73. And a Hall IC 82 mounted on a substrate 84 disposed on the side of the output shaft 73. Here, in FIG. 4, the position of the magnet 81 when the door body 4 is in the flat posture shown by the solid line in FIG. 2C is shown by a solid line, and the output shaft 73 rotates 45 °, and the door body The position of the magnet 81 when 4 is in the oblique posture shown by the one-dot chain line in FIG. 2C is shown by the one-dot chain line. Further, when the door body 4 is in an oblique posture indicated by a one-dot chain line in FIG. 2C, the door body 4 is in a fully open position, and in this state, the Hall IC 82 is in an output state, and the other states Indicates no output. Therefore, in the sensor 8, the state where the output of the Hall IC 82 is not output continues until the sensor 8 reaches the posture inclined 45 ° obliquely downward indicated by the one-dot chain line from the flat posture indicated by the solid line in FIG. Since the Hall IC 82 is in an output-provided state when the posture is inclined 45 ° obliquely downward indicated by a one-dot chain line, the sensor 8 can monitor the posture of the door body 4.

(Operation)
In this embodiment, when the door body 4 is rotated to the ice storage chamber 3 side, it is detected by the sensor 8 whether or not the door body 4 is inclined at an angle of 45 ° downward. Based on the detection result, the ice storage chamber 3 is detected. The amount of ice stored in the is detected. Such an operation will be described below with reference to FIGS.

  FIG. 5 and FIG. 6 are respectively an explanatory diagram when the ice in the ice storage chamber is small and an explanatory diagram when there is a lot of ice in the ice storage chamber in the ice manufacturing and storage apparatus to which the present invention is applied.

  First, the case where the ice in the ice storage chamber 3 is small will be described with reference to FIG. In a state where the door body 4 is indicated by a solid line in FIG. 5, the door body 4 is in a flat posture, and the opening 110 (the opening 90 of the partition wall 9) of the frame 11 is closed by the door body 4. In this state, the door body driving device 7 drives the motor 71 by a predetermined number of steps at a predetermined timing. As a result, the door body 4 rotates in the ice storage chamber 3 side (counterclockwise CCW direction). At that time, since there is little ice in the ice storage chamber 3, the lever-shaped ice detecting section 6 does not interfere with the ice, and the door body 4 switches to a posture inclined 45 ° obliquely downward as indicated by a one-dot chain line in FIG. As a result, the sensor 8 switches the output of the Hall IC 82 from “no” to “present”, so that it can be detected that the ice storage chamber 3 has little ice. Therefore, after the ice tray 21 is reversed by the rotation mechanism 22, the ice tray 21 is heated. As a result, the ice is detached from the ice tray 21 by its own weight, and then moves to the ice storage chamber 3 through the openings 90 and 110. At that time, since the elastic sheet 53 is stuck on the entire surface of the ice making chamber 3 in the lid body 5, the ice separated from the ice tray 21 in the ice making chamber 2 hits the elastic sheet 53 of the door 4. The falling sound of ice can be reduced.

  In moving the ice from the ice tray 21 to the ice storage chamber 3, as shown by a solid line in FIG. 5, the door body 4 is rotated clockwise in the direction of CW to obtain a flat posture, and then the ice tray 21 is moved. , And the ice is received on the upper surface of the door main body 5, and then the door body 4 is rotated again to the ice storage chamber 3 side to move the ice on the door body 4 to the ice storage chamber 3. At that time, since the elastic sheet 53 is adhered to the entire surface on the ice making chamber 3 side, the ice released from the ice tray 21 in the ice making chamber 2 can be received by the elastic sheet 53 of the door body 4. Therefore, the falling sound of ice can be reduced. Further, since the ice is once received at a position close to the ice tray 21, it is effective in reducing the falling sound of ice.

  Next, the case where there is much ice in the ice storage chamber 3 is demonstrated with reference to FIG. Also in this case, in a state where the door body 4 is shown by a solid line in FIG. 6, the door body 4 is in a flat posture, and the opening 90 of the partition wall 9 is blocked by the door body 4. In this state, the door body driving device 7 drives the motor 71 by a predetermined number of steps at a predetermined timing. As a result, the door body 4 rotates to the ice storage chamber 3 side (counterclockwise CCW direction). However, since there is a lot of ice in the ice storage chamber 3, the lever-shaped ice detecting section 6 interferes with the ice and the door body 4 Rotation is prevented. Therefore, the door body 4 stops in the middle of switching to a posture inclined 45 ° obliquely downward, as indicated by a one-dot chain line in FIG. Accordingly, in the sensor 8, the output of the Hall IC 82 does not switch from “No” to “Yes”. Therefore, if the output of the Hall IC 82 does not switch from “No” to “Yes” even after a predetermined time has elapsed, Many can detect that they cannot store ice any more. Therefore, the ice body 21 is not deiced, and the door body 4 is rotated in the clockwise direction CW to return to the flat posture.

(Main effects of this form)
As described above, in the ice manufacturing and storage apparatus 1 according to the present embodiment, since the door body 4 is disposed between the ice making chamber 2 and the ice storage chamber 3, the ice making chamber 2 and the ice storage chamber 3 are usually connected to the door body. Therefore, the ice making chamber 2 and the ice storage chamber 3 can be kept at the optimum temperatures. Further, when the ice is moved from the ice making chamber 2 to the ice storage chamber 3, the door body 4 can be displaced by the door body driving device 7 so that the ice making chamber 2 and the ice storage chamber 3 are in communication with each other. Here, when the ice making chamber 2 and the ice storage chamber 3 are communicated with each other, the door body 4 is displaced toward the ice storage chamber 3, so that the door body 4 is also detected when the amount of ice in the ice storage chamber 3 is detected. Displace toward. At that time, if the ice amount in the ice storage chamber 3 is small, the door body 4 and the ice do not interfere with each other, and the displacement of the door body 4 is not hindered, whereas if the ice amount in the ice storage chamber 3 is large, The door body 4 interferes with ice and is prevented from being displaced. Therefore, if it is detected whether or not the displacement of the door body 4 is blocked by the sensor 8, the amount of ice in the ice storage chamber 3 can be detected. Therefore, since the amount of ice in the ice storage chamber 3 can be detected by the same operation as moving the door body 4 when the ice is moved from the ice making chamber 2 to the ice storage chamber 3, the ice storage chamber 3 becomes the ice making chamber. 2, the amount of ice stored in the ice storage chamber 3 can be detected with a simple configuration.

  Further, in this embodiment, the door body driving device 7 rotates the door body 4 around the base end side to the ice storage chamber 3 side so that the ice making chamber 2 and the ice storage chamber 3 communicate with each other. The door drive device 7 having the configuration can be driven. Moreover, since the ice storage chamber 3 is located below the ice making chamber 2, the ice removed from the ice tray 21 in the ice making chamber 2 can be moved to the ice storage chamber 3 by its own weight.

  Furthermore, the door body 4 includes a door main body 5 for partitioning the ice making chamber 2 and the ice storage chamber 3, and a lever-shaped ice detecting portion 6 protruding from the door main body 5 to both the front end side and the ice storage chamber 3 side. Therefore, the door body 5 can be divided into a shape suitable for separating the ice making chamber 2 and the ice storage chamber 3, and only the lever-shaped ice detecting section 6 is suitable for detecting ice. What is necessary is just a structure. Moreover, since the lever-shaped ice detecting section 6 is disposed at a substantially central position in the width direction of the door body 5, even when the ice is piled up near the center of the ice storage chamber 3, the lever-shaped ice detecting section 6 is provided. Since the unit 6 interferes with the top of the ice or the vicinity thereof, it can be reliably detected whether or not the ice can be newly moved to the ice storage chamber 3. The lever-shaped ice detecting section 6 is made of a thin plate having an in-plane direction in the direction of movement of ice from the ice making chamber 2 to the ice storage chamber 3, so that the ice making chamber 2 and the ice storage chamber 3 communicate with each other. When the ice is moved from the ice storage chamber 3 to the ice storage chamber 3, the lever-shaped ice detecting section 6 does not get in the way while the ice moves.

[Other embodiments]
In the above embodiment, since the lever-shaped ice detecting section 6 is fixed to the door main body 5, the sensor 8 monitors the posture of the door body 4, but the ice detecting section is supported by the door main body 5 so as to be displaceable. When the ice detecting section is monitored by the detector and the door body 4 is displaced toward the ice storage chamber 3 side, the ice detecting section is displaced with respect to the ice in the ice storage chamber 3 and displaced with respect to the door body 5. Alternatively, it may be detected that a predetermined amount or more of ice is stored in the ice storage chamber 3.

  Moreover, in the said form, although the ice detection part was formed in lever shape, a rod-shaped thing may be used and the number may be plural. Furthermore, depending on the shape of the door body 5, the door body 5 itself may be used as the door body 4 to detect whether the door body 5 interferes with ice.

  Further, in the above embodiment, the magnetic sensor 8 such as the magnet 81 and the Hall IC 82 is used as the detector for detecting the position of the lever-shaped ice detecting unit 6, but an optical switch such as a photo interrupter or a tact switch A mechanical switch such as may be used.

  Furthermore, in the above embodiment, the ice making chamber 2 and the ice storage chamber 3 are arranged vertically, but the present invention is applied to an ice manufacturing and storage device in which the ice making chamber 2 and the ice storage chamber 3 are arranged in the horizontal direction. In this case as well, the amount of ice may be detected by displacing the door to the ice storage chamber 3 side.
