  Hereinafter, embodiments of a refrigerator with an ice making device according to the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 4, the refrigerator 1 with an ice making device is set in a refrigerating room 2 set in the upper part, a freezing room 3 set in the lower part of the refrigerating room 2, and an upper part in the freezing room 3. The ice making chamber 4 and the ice making device 5 provided in the ice making chamber 4 are further provided. The ice making device 5 further supports an ice making tray 8 having a plurality of ice making recesses 7 and an ice making tray 8. And supporting the ice tray 8 in a plurality of postures of a horizontal posture parallel to the horizontal plane and an inclined posture inclined with respect to the horizontal plane. The posture and the inclined posture can be switched.

  The ice tray 8 is formed by arranging a plurality of ice making recesses 7 in, for example, two rows on the left and right and four rows on the front and rear when viewed from the front side of the refrigerator 1, and the plurality of ice making recesses 7 are formed in the same shape. . In the center of the front side end of the ice tray 8, an engagement hole 11 having a horizontally long cross-section is formed to insert and engage a rotation drive shaft 16 to be described later, and the center of the rear side end of the ice tray 8 is formed. In addition, a both-end supporting shaft 12 having a circular cross section supported by a both-end supporting portion 18 described later is provided. The ice tray 8 is provided with an ice making thermistor to detect ice making.

  The support unit 9 includes a drive unit 13 for rotatably supporting the ice tray 8 and a support plate 14 that supports the ice tray 8 and the drive unit 13 and covers the upper side and the periphery thereof. The space partitioned by is the ice making chamber 4. An ice storage case 15 is provided below the ice making chamber 4 to store the ice made by the ice making device 5.

  As shown in FIGS. 2 to 4, the drive unit 13 is provided with a rotary drive shaft 16 that is inserted into the engagement hole 11 of the ice tray 8 to support the ice tray 8 and can be rotated. The rotation drive shaft 16 rotates around its central axis to rotate the ice tray 8, whereby the ice made is detached from the ice tray 8 and dropped into the ice storage case 15.

  The engagement hole 11 and the insertion site of the rotary drive shaft 16 into the engagement hole 11 are set to a size that allows the insertion site of the rotary drive shaft 16 to be inserted into the engagement hole 11 and engaged with each other. It is formed in a flat cross section so that the rotation of the rotation drive shaft 16 can be transmitted to the ice tray 8. The engagement hole 11 has a cross-sectional shape that is set to be horizontally long and flat, and the short-side dimension of the cross-sectional shape is longer than the short-side dimension of the cross-sectional shape of the insertion portion of the rotary drive shaft 16 and is inserted. It is set shorter than the longitudinal dimension of the cross-sectional shape of the part.

  The engaging hole 11 and the rotary drive shaft 16 can be gently engaged by inclining the short direction of each other to tilt the ice tray 8, and the flat end portions of the flat plate are rotated by rotating the rotary drive shaft 16. Is pressed against the upper and lower surfaces of the engagement hole 11 so that the ice tray 8 can be supported horizontally and supported horizontally. As a result, the rotational drive shaft 16 is rotated relative to the ice tray 8 around the central axis, and the horizontal position of the ice tray 8 and the axial direction in which the ice tray 8 is inclined in the central axis direction of the rotational drive shaft 16. The inclination posture can be switched.

  A slit-like guide portion 17 that guides the both-end supporting shaft 12 of the ice tray 8 in the vertical direction is formed in a portion of the support plate 14 that covers the back side of the ice tray 8. When the ice tray 8 is switched between the horizontal posture and the axially inclined posture, the guide portion 17 guides the side of the ice tray 8 opposite to the rotation drive shaft 16 in the vertical direction to prevent the ice tray 8 from being laterally displaced. To do.

  When the ice tray 8 is switched to the axially inclined posture, the lower end of the guide portion 17 receives the both-end supported shaft 12 of the ice tray 8 and both the ice tray 8 to the axially tilted posture with the rotary drive shaft 16. It is set as the both-ends support part 18 which supports. The double-supported support portion 18 is configured to receive only the double-supported shaft 12 of the ice tray 8, and when the ice tray 8 is switched to the horizontal posture, the double-supported shaft 12 moves upward along the guide portion 17. Thus, the support for the ice tray 8 is released.

  Water to be supplied to the ice tray 8 is stored in a water supply tank 19 provided in the refrigerator compartment 2, and ice is made from the water supply tank 19 through a water supply pump 20, a water supply pipe 21, and a water supply unit 22 set at the discharge port. Water is supplied to the dish 8. In FIG. 1, 23 is a pipe heater, 24 is a cold air circulation fan, 25 is an evaporator, and 26 is a tank heater.

  According to the above configuration, the rotational drive shaft 16 is inserted into the engagement hole 11 of the ice tray 8 to be cantilevered, and the transverse dimension of the cross-sectional shape of the engagement hole 11 is determined at the insertion site of the rotational drive shaft 16. It is set longer than the dimension in the short direction of the cross-sectional shape. Thus, the rotation drive shaft 16 can be rotated to switch between the horizontal posture and the axially inclined posture of the ice tray 8, and ices of various sizes can be selected by appropriately selecting the posture of the ice tray 8 during ice making. Can be made into ice.

  Specifically, the procedure will be described. First, the rotational drive shaft 16 is rotated in the opposite direction (counterclockwise in FIG. 4) to the direction of icing from the ice tray 8, and both ends of the insertion site of the rotational drive shaft 16 are rotated. The portion is pressed against the upper and lower surfaces of the engagement hole 11, and the engagement hole 11 and the rotary drive shaft 16 are strongly engaged to support the ice tray 8 in a horizontal position (FIGS. 1, 2A, 3). (See (a) and FIG. 4 (a)). By supplying water to the ice tray 8 in the horizontal position, water can be supplied from the water supply unit 22 to the ice tray 8 without spilling water from the ice tray 8.

  When large, medium, and small sizes of ice having different sizes are made after supplying water to the ice tray 8, the rotary drive shaft 16 is rotated in the direction of removing the ice from the ice tray 8 (clockwise in FIG. 4). The flat shape is adjusted in the horizontal direction, and the engagement hole 11 and the rotary drive shaft 16 are gently engaged. In this state, there is a gap between the upper and lower surfaces of the engagement hole 11 and the insertion site of the rotary drive shaft 16, and the ice tray 8 is inclined with respect to the rotary drive shaft 16 by its own weight and the weight of water. The ice tray 8 is supported in an axially inclined posture by being guided downward along the guide portion 17 until the support shaft 12 is supported by the both-end support portions 18 of the support plate 14 (FIG. 2B). 3 (b), see FIG. 4 (b)).

  In this case, since the ice tray 8 is inclined after the water supply, the water surface 27 can be inclined relative to the ice tray 8 without spilling water from the ice tray 8, and by making ice as it is, a large size can be obtained. Large, medium and small ices of different sizes can be made.

  In addition, when a plurality of pieces of ice having the same size are made after supplying water to the horizontal ice tray 8, the horizontal position of the ice tray 8 is maintained without rotating the rotary drive shaft 16, and the ice tray 8. The ice surface may be made without inclining the water surface 27.

  After making the ice, the rotary drive shaft 16 is rotated in the direction of removing the ice from the ice tray 8 (clockwise in FIG. 4), and the both ends of the insertion portion of the rotary drive shaft 16 are turned upside down from the horizontal posture at the time of water supply. Then, the ice tray 8 is pressed against the upper and lower surfaces of the engagement hole 11 and supported in a horizontal posture (see FIG. 4C). Furthermore, by rotating the rotary drive shaft 16 in the direction of deicing from the ice tray 8 (clockwise in FIG. 4) while restricting the rotation of the rear side end of the ice tray 8 with a stopper (not shown), The ice tray 8 is twisted to release the ice.

  After removing the ice from the ice tray 8, the stopper is released and the ice tray 8 is rotated by the rotation drive shaft 16 to drop the ice in the ice storage case 15 and store it.

  In addition, this invention is not limited to said embodiment, A change can be suitably added within the scope of the present invention. For example, instead of forming the engagement hole 11 in the ice tray 8 and inserting the insertion portion of the rotation drive shaft 16, the insertion hole may be formed in the ice tray 8 by forming the engagement hole in the rotation drive shaft 16. Good. Further, instead of setting the engagement hole 11 and the insertion site to have a flat cross section, the cross-sectional shape of the insertion site is changed in the axial direction, and the insertion site is moved in the axial direction to switch the engagement state with the engagement hole. You may do it. That is, as a part of the support portion, an engaging portion that can be engaged with the rotation drive shaft 16 is formed in the ice tray 8 and the engagement state between the rotation drive shaft 16 and the engagement portion is switched. Accordingly, the horizontal posture of the ice tray 8 and the axially inclined posture of the ice tray 8 may be switched.

  Further, instead of cantilevering the ice tray 8 in a horizontal posture with the rotation drive shaft 16, the rotation can be supported by the rotation drive shaft 16 and the both-end support portion 18. Specifically, for example, as shown in FIG. 5, the engagement plate 28 is provided at the front side end of the ice tray 8 to form the slide grooves 29 and 30, and the engagement protrusions 31 and 32 are formed on the rotary drive shaft 16. By providing and moving along the slide grooves 29, 30, the front end of the ice tray 8 can be moved up and down to switch between the horizontal posture of the ice tray 8 and the axially inclined posture of the ice tray 8.

  In FIG. 5, the slide groove 29 is formed in the horizontal direction and the engagement protrusion 31 is engaged, and the slide groove 30 is formed in the substantially vertical direction and the engagement protrusion 32 is engaged. In FIG. 5 (a), the engaging projection 32 is positioned at the lower end of the slide groove 30 to place the ice tray 8 in a horizontal posture, and the ice making tray 8 is rotated by rotating the rotary drive shaft 16 clockwise from this state. And can be deiced. Further, by rotating the rotary drive shaft 16 counterclockwise from the state of FIG. 5A, the engaging protrusion 32 moves upward along the slide groove 30 as shown in FIG. While the engagement protrusion 31 moves to the right along the slide groove 29, the engagement plate 28 is pushed down by the height (h), so that the ice tray 8 is inclined in the axial direction.

  Further, as shown in FIG. 6, in order to switch between the horizontal posture and the inclined posture of the ice tray 8, not only the ice tray 8 is set to the axially tilted posture but also the rotation drive shaft 16 is rotated around its central axis. By rotating the ice tray 8, the horizontal posture of the ice tray 8 and the axially inclined posture in which the ice tray 8 tilts in a direction orthogonal to the central axis direction of the rotation drive shaft 16 may be switched. Good.

  In this case, after supplying water in the horizontal position of the ice tray 8 shown in FIG. 6 (a), the rotary drive shaft 16 is rotated in the direction of separating the ice from the ice tray 8 (clockwise in FIG. 6) and stopped. The water surface 27 is inclined relative to the ice tray 8 in the axially inclined posture shown in FIG. After making ice in this axially inclined posture, the rotary drive shaft 16 is further rotated to separate the ice, whereby large and small ices having different sizes can be made in the left and right ice making recesses 7.

  Further, as described above, the insertion hole 11 and the rotational drive shaft 16 are set in a flat shape so that the ice tray 8 can be set in an axially inclined posture, and the ice tray 8 can be stopped during rotation. Thus, it may be possible to set the tilting direction perpendicular to the axis. Thereby, the ice tray 8 can be switched to both the axially inclined posture and the axially inclined posture, and uniform size ice, large / medium size ice, or large / small size ice can be appropriately selected. it can.

  Further, the number of the ice making recesses 7 may be any number and may not necessarily have the same shape. Further, the rotation drive shaft 16 is not only used for the switching of the attitude of the ice tray 8 and the rotational drive of the ice tray 8 at the time of deicing, but a dedicated switching structure is provided to switch the attitude of the ice tray 8. Also good.

  As is clear from the above description, the refrigerator 1 with an ice making device according to the present invention is an ice making chamber 4 equipped with an ice making device 5, and the ice making device 5 further has an ice making tray 8 having a plurality of ice making recesses 7. And a support portion 9 that supports the ice tray 8. The support portion 9 can support the ice tray 8 in a horizontal posture parallel to the horizontal plane and an inclined posture inclined with respect to the horizontal plane. The horizontal posture and the inclined posture can be switched.

  According to this configuration, since the ice tray 8 can be supported in an inclined posture inclined with respect to the horizontal plane, a plurality of types of ice having different sizes can be made by one ice making. Moreover, since it is possible to switch between the horizontal posture and the inclined posture of the ice tray 8, it is possible to appropriately select whether to make ice of a uniform size or to make a plurality of types of ice having different sizes.

  Further, the support unit 9 is provided with a rotation drive shaft 16 that supports and rotates the ice tray 8, and the ice tray 8 is rotated by rotating the rotation drive shaft 16 around its central axis so that it can be deiced. Also good. According to this configuration, the rotation drive shaft 16 is provided to the support portion 9 for switching the attitude of the ice tray 8 and the ice tray 8 is rotated by the rotation drive shaft 16 to separate the ice. 8 can be used both for switching the posture and for removing the ice from the ice tray 8.

  Further, the rotation drive shaft 16 may be capable of supporting the ice tray 8 in a cantilever manner. According to this configuration, since the ice tray 8 is cantilevered, it is possible to switch the posture of the ice tray 8 by moving the end of the ice tray 8 slightly by moving the end of the ice tray 8 slightly. The structure for switching the posture of the ice tray 8 can be reduced in size.

  In addition, the support portion is provided with an engaging portion formed on the ice tray 8 so as to be engageable with the rotation drive shaft 16, and by switching the engagement state between the rotation drive shaft 16 and the engagement portion, the ice tray 8 can be placed horizontally. It is possible to switch between the attitude and the axial inclination attitude that is inclined in the central axis direction of the rotation drive shaft 16 in the inclination attitude of the ice tray. According to this configuration, since the engaging portion is formed in the ice tray 8 and is engaged with the rotational drive shaft 16, the rotational drive shaft 16 for separating the ice from the ice tray 8 can be removed simply by switching the engagement state. It is possible to switch the posture of the ice tray 8 by using it.

  More specifically, the ice tray 8 is formed with an engagement hole 11 into which the rotation drive shaft 16 is inserted and engaged, and the cross-sectional shape of the engagement hole 11 is set to be a horizontally long flat shape. The insertion portion of the engagement hole 11 is set to have a flat cross-sectional shape that can be inserted into the engagement hole 11, and the short-side dimension of the cross-sectional shape of the engagement hole 11 is set as the insertion portion of the rotary drive shaft 16. By setting the rotation drive shaft 16 around the central axis relative to the ice tray 8 to be longer than the cross sectional shape in the short direction and shorter than the longitudinal size of the cross section of the insertion site. The horizontal posture of the ice tray 8 and the axially inclined posture inclined in the central axis direction of the rotation drive shaft 16 in the inclined posture of the ice tray 8 may be switchable.

  According to this configuration, the engagement hole 11 and the insertion site of the rotary drive shaft 16 are set to have a flat cross section, and the flat short dimension of the engagement hole 11 is set to the flat short width of the rotary drive shaft 16. Since it is set to be longer than the directional dimension, the engagement state between the engagement hole 11 and the rotation drive shaft 16 can be switched by appropriately rotating the rotation drive shaft 16.

  That is, by rotating the rotation drive shaft 16 as appropriate, both flat end portions of the rotation drive shaft 16 are pressed against the upper and lower surfaces of the engagement hole 11 and the engagement hole 11 and the rotation drive shaft 16 are strongly engaged. The ice tray 8 can be switched to the horizontal posture. Further, by rotating the rotary drive shaft 16 as appropriate, the engagement hole 11 and the rotary drive shaft 16 are gently engaged with each other in accordance with the flat short direction of the engagement hole 11 and the rotary drive shaft 16. The ice tray 8 can be tilted with respect to the rotational drive shaft 16 to switch the ice tray 8 to the axially inclined posture.

  Furthermore, the ice making tray 8 is set to an axially inclined posture by rotating the rotary drive shaft 16 to adjust the flat shape of the insertion site in the horizontal direction, and in the direction opposite to the direction in which the ice making tray 8 is rotated and deiced. The ice tray 8 may be set in a horizontal posture by rotating the rotation drive shaft 16. According to this configuration, when the ice tray 8 is set to the horizontal posture, the rotation drive shaft 16 is rotated in the direction opposite to the direction of deicing, so that the ice tray 8 is rotated by an accurate rotation amount in the middle of the deicing direction. It is not necessary to stop the drive shaft 16, and the horizontal position of the ice tray 8 can be more reliably maintained.

  Further, on the side of the ice tray 8 opposite to the rotation drive shaft 16, there is provided a both-end support part 18 that supports the ice tray 8 in an axially inclined posture with respect to the rotation drive shaft 16. The part 18 may be disengageable from supporting the ice tray 8 in a horizontal posture. According to this configuration, since the ice making tray 8 tilted in the axial direction is supported at both ends by the rotary drive shaft 16 and the both-end support portion 18, the ice making tray 8 is stably supported while being tilted. The direction inclination posture can be maintained.

  Moreover, you may provide the guide part 17 which guides the opposite side to the rotational drive shaft 16 of the ice tray 8 to an up-down direction. According to this configuration, since the guide portion 17 guides the opposite side of the ice tray 8 in the vertical direction, it is possible to prevent lateral displacement of the ice tray 8 supported in a cantilever manner.

  Further, by rotating the rotation drive shaft 16 around its central axis and rotating the ice tray 8, the horizontal position of the ice tray 8 and the direction of the central axis of the rotation drive shaft 16 in the inclined position of the ice tray 8 It may be possible to switch between the axial inclination postures inclined in the orthogonal direction. According to this configuration, since the ice tray 8 is rotated by the rotation drive shaft 16 to be inclined in the axial direction, the structure for switching the posture of the ice tray 8 can be simplified.

  Moreover, the water supply part 22 which supplies water to the ice tray 8 may be provided, and the ice tray 8 may be in a horizontal posture when water is supplied from the water supply unit 22 and in an inclined posture after water supply. According to this configuration, since the ice tray 8 is set in a horizontal posture when water is supplied from the water supply unit 22, water can be supplied without spilling water from the ice tray 8.

  Moreover, you may form several ice-making recessed parts in the same shape. According to this configuration, it is possible not only to make a plurality of types of ice with different sizes by making the ice tray 8 in an inclined posture, but also to make ice of a uniform size by making the ice tray 8 in a horizontal posture.

  Further, a water supply tank 19 for storing water to be supplied to the ice tray 8 may be provided in the refrigerator compartment 2. According to this configuration, since the water supply tank 19 is provided in the refrigerator compartment 2, it is possible to save the trouble of supplying water to the ice tray 8 and to keep the water supplied to the ice tray 8 in the refrigerator compartment 2. The time required for ice making can be shortened.
