Description

  The present invention relates to an ice making machine configured such that a shaft support portion of a water tray is supported by a shaft with respect to a support portion provided on an attachment frame, and the water tray can be tilted with respect to an ice making portion.

  As shown in FIG. 7, ice making water is jetted and supplied to a ice making chamber 64a that opens downward from the ice making chamber 64a, and the ice making water is jetted and supplied from a water tray 66 that closes the ice making chamber 64a. There is known an automatic ice making machine provided with a so-called closed cell type ice making mechanism 62 configured to be released by tilting a water dish 66 in a direction away from the ice making chamber 64 (see, for example, Patent Document 1). ).

As shown in FIG. 7, a mounting frame 60, which is an object for disposing the ice making mechanism 62, is installed in the left-right direction above the box 12 in the ice making machine. The water pan 66 supports a pair of shaft support portions 68 and 68 supported by a shaft 70 with respect to a pair of support portions 61 and 61 spaced apart in the front-rear direction of the box 12 on the lower surface of the mounting frame 60. Thus, it is arranged to be tiltable in the vertical direction. As shown in FIG. 8, each support portion 61 is a U-shaped member that opens downward and is fastened to the mounting frame 60 with screws 78 and 78, and an axis that allows the shaft 70 to be inserted into the vertical portion. The holes 61a are opened in a state where they are aligned in the front-rear direction. The upper ends of the shaft support portions 68 are arranged between the vertical portions of the corresponding support portions 61, and the shaft holes 68a penetrating along the front-rear direction at the upper ends of the shaft support portions 68 are connected to the shaft holes 61a and 61a. Align. In this state, by inserting the shaft 70 in common into the shaft holes 68 a, 61 a, 61 a, the respective shaft support portions 68 are rotatably supported by the respective support portions 61 by the shaft 70. At this time, the shaft 70 has a large-diameter locking piece 70 a formed at one end abutting against one side surface of the support portion 61 and attaching a snap pin 72 to the other end protruding from the other side surface of the support portion 61. The movement in the front-rear direction is restricted so that it does not fall off from the support portion 61.
Japanese Utility Model Publication No. 4-11367

  By the way, since the water pan 66 becomes dirty over time due to impurities contained in tap water used as ice making water, it is necessary to remove it from the box 12 and perform maintenance such as cleaning as needed. In the ice making mechanism 62 described above, after removing the coil spring 76 of the water dish tilting mechanism 74 that supports the open end side of the water dish 66, each snap pin 72 is removed from the shaft 70, and each shaft 70 is supported by the support portion. The water pan 66 is removed from both the support parts 61 and 61 by extracting from 61 and the shaft support part 68. FIG. In this way, the shaft 70 cannot be removed unless it is completely removed from the support portion 61 and the shaft support portion 68, and it becomes an attaching / detaching operation in a narrow place in the box 12, so that the shaft 70 can be dropped or the shaft can be removed. 70 may be lost. In order to solve this problem, it is conceivable that the shaft 70 is integrally formed with the support portion 61 or the shaft support portion 68. However, with the synthetic resin shaft integrally formed with the support portion 61 or the shaft support portion 68 made of synthetic resin, If the plate 66 is enlarged, it cannot withstand its weight. In addition, a synthetic resin shaft may be inferior in durability, and a separate metal shaft may have to be used.

  That is, the present invention has been proposed in view of the above-described problems inherent in the ice making machine according to the prior art, and has been proposed to suitably solve these problems. An object of the present invention is to provide an ice making machine that can prevent the shaft from dropping or losing when it is removed.

In order to overcome the above-mentioned problems and achieve the intended purpose, an ice making machine according to claim 1 of the present application provides:

The shafts 52A and 52B are provided with round bar-shaped shafts 52A and 52B, and are provided at one ends of the shafts 52A and 52B. There are provided locking pieces 54A and 54B which are formed to protrude radially outward from the surface. Further, the first locking piece 54A of the first shaft 50A has a first connecting shaft portion with a radius connecting a line connecting the axis of the first shaft portion 52A and the outer peripheral edge of the first locking piece 54A closest to the axis. A restricting portion 56 that protrudes outward in the radial direction from a locus drawn around the axis of 52A is provided. That is, the first locking piece 54A is set to a simple non-circular shape in which the outer peripheral edge is located on the same radius locus centering on the axis of the first shaft portion 52A. As shown in FIG. 4, the first locking piece 54A of the embodiment is formed in a substantially oval shape in which the outer peripheral edge is chamfered with a rectangular corner, and the first shaft portion 52A is the first locking piece 54A. In the center in the direction along the short side, the connection is biased to one short side. That is, in the first locking piece 54A, the first shaft portion 52A is separated from the restricting portion 56 and connected to a position shifted from the center of gravity of the first locking piece 54A, and the first shaft portion 52A is connected to the first locking piece 54A. The other short side opposite to the short side functions as the restricting portion 56. The first shaft portion 52A is provided with an insertion hole 53 through which the snap pin 72 is inserted so as to penetrate in the radial direction (see FIG. 3). On the other hand, in the second shaft 50B, the second locking piece 54B is formed in a circular shape with the outer periphery located on the same radius with the axis of the second shaft portion 52B as the center, and the second locking piece 54B is The second shaft portion 52B is connected coaxially.

On the other hand, the insertion edges of the locking pieces 54A and 54B are restricted at the opening edges of the shaft holes 26A and 26B.

  A plate-like stopper portion 28 is suspended from the lower surface of the mounting frame 22 so as to face the rear surface of the first support portion 24A. The stopper portion 28 is formed integrally with the synthetic resin mounting frame 22, and is spaced from the rear surface of the first support portion 24A by a distance greater than the thickness of the first locking piece 54A and smaller than the length of the first shaft 50A. Be placed. The stopper portion 28 is provided with a through hole 30 that is located on the axis of the first shaft hole 26A in the first support portion 24A and penetrates in the front-rear direction. The size and shape of the through hole 30 allow the first locking piece 54A to be inserted in the first posture in which the first shaft 50A faces the restricting portion 56 upward (see FIG. 3B), In the second posture in which the restriction portion 56 is directed downward by turning 180 ° around the axis of the first shaft portion 52A from the first posture (see FIG. 3C), the insertion of the first locking piece 54A is restricted. Set to do.

  The dimension of the through hole 30 from the axis line of the first shaft hole 26A passing through the through hole 30 to the opening edge is from the axis line of the first shaft part 52A to the outer peripheral edge of the restricting part 56 in the first locking piece 54A. The stopper portion 28 is formed to have a portion larger than the size and a portion smaller than the size. Here, in the through hole 30, the portion of the first locking piece 54 </ b> A that is smaller than the dimension from the axis of the first shaft portion 52 </ b> A to the outer peripheral edge of the restricting portion 56 is positioned below the axis of the first shaft hole 26 </ b> A. Is set as follows. That is, in the first posture of the first shaft 50A in which the axis of the first shaft portion 52A is aligned with the first shaft hole 26A (see FIG. 3B), the through-hole 30 extends from the axis of the first shaft hole 26A. The restricting portion 56 faces a portion where the dimension to the opening edge is set larger than the dimension from the axis of the first shaft portion 52A to the outer peripheral edge of the restricting portion 56, and the through hole 30 and the first locking piece 54A are aligned. It is like that. On the other hand, in the second posture of the first shaft 50A in which the axis of the first shaft portion 52A is aligned with the first shaft hole 26A (see FIG. 3C), the first shaft hole 26A is formed in the through hole 30. The restricting portion 56 faces a portion where the dimension from the axis to the opening edge is set smaller than the dimension from the axis of the first shaft portion 52A to the outer peripheral edge of the restricting portion 56, and the through hole 30 and the first locking piece 54A are located. Configured to be inconsistent. The through-hole 30 of the embodiment is formed in a slightly similar shape with respect to the outer peripheral shape of the first locking piece 54A, and has an oval shape whose longitudinal length extends in the vertical direction (see FIG. 4). In addition, the through hole 30 is disposed at a position where the axis of the first shaft hole 26 </ b> A passes through a portion biased downward in the stopper portion 28 at the center in the left-right direction of the through hole 30.

  The pair of shaft support portions 44 </ b> A and 44 </ b> B are plate-like portions that protrude upward from the upper surface of the water dish 42, and are provided apart from each other in the front-rear direction of the box 12 while facing the left side of the water dish 42. It has been. Holes 46A and 46B that align with the shaft holes 26A and 26B of the corresponding support portions 24A and 24B are opened in the front-rear direction at the upper portions of the shaft support portions 44A and 44B, respectively. The shaft portions 52A and 52B are allowed to be inserted. Further, in the second shaft support portion 44B, the second shaft portion 52B is inserted into the second hole portion 46B from the front side, the second locking piece 54B is brought into contact with the front surface, and the second shaft portion 52B is moved to the rear side. The second shaft 50B is fixed in a protruding state.

  In the water tray 42, both shaft support portions 44A and 44B are positioned in front of the corresponding support portions 24A and 24B, and the second shaft portion 52B of the second shaft 50B fixed in advance to the second shaft support portion 44B is a second shaft hole. 26B is configured to be inserted from the front side. Further, the water tray 42 is inserted through the first shaft portion 52A of the first shaft 50A in common through the first shaft hole 26A and the first hole portion 46A of the first shaft support portion 44A from the rear side of the first support portion 24A. Can be assembled. Here, the first shaft portion 52A protruding to the front side of the first shaft support portion 44A is inserted into the insertion hole 53, and the snap pin 72 is attached thereto, thereby restricting the movement of the first shaft 50A in the front-rear direction. As described above, the front shaft support of the front and rear shaft supports is operated so that the first shaft 50A inserted from the rear side into the first shaft hole 26A of the first support portion 24A is in the first posture. As long as there is not, the stopper part 28 which controls the movement to the back side is provided.

(Effects of Example)
Next, the operation of the ice making machine 10 according to the embodiment will be described. When the water tray 42 is attached to the attachment frame 22, the first shaft portion 52A is inserted into the through hole 30 from the rear side of the stopper portion 28 in the first posture with the restriction portion 56 of the first shaft 50A facing upward. Further, the first shaft portion 52A is inserted into the first shaft hole 26A of the first support portion 24A (see FIG. 3B). At this time, since the first shaft 50A in the first posture is in a state where the through hole 30 and the first locking piece 54A are aligned, the first locking piece 54A also passes through the through hole 30, and the first The locking piece 54A is located between the stopper portion 28 and the first support portion 24A. The first shaft 50A inserted through the first shaft hole 26A is rotated in the circumferential direction around the axis of the first shaft portion 52A, thereby converting the first posture into the second posture with the regulating portion 56 directed downward ( (See FIG. 3B or FIG. 4 two-dot chain line). As a result, the through hole 30 and the first locking piece 54A are in an inconsistent state. Therefore, the first locking piece 54A has the restriction portion 56 locked to the opening edge of the through hole 30 in the stopper portion 28. The rearward movement is restricted.

  The second shaft portion 52B of the second shaft 50B inserted and fixed in the second hole portion 46B of the second shaft support portion 44B of the water tray 42 is inserted from the front side into the second shaft hole 26B of the second support portion 24B. Thus, the rear side of the water tray 42 is held by the second support portion 24B. Further, the first shaft support portion 44A of the water tray 42 is positioned on the front side of the first support portion 24A, and the first shaft hole 26A and the first hole portion 46A are aligned. When the first shaft 50A is moved forward, the first shaft portion 52A is inserted into the first hole portion 46A. At this time, the first shaft 50A is restricted from moving forward by the first locking piece 54A coming into contact with the rear surface of the first support portion 24A. Then, by inserting the snap pin 72 into the insertion hole 53 of the first shaft portion 52A protruding to the front side of the first shaft support portion 44A, the first shaft 50A is caused by the snap pin 72 protruding to the peripheral surface of the first shaft portion 52A. The movement to the rear side is restricted, and the movement to the front side of the first shaft support portion 44A is restricted. In each of the front and rear shaft supports of the water tray 42, the shaft support portions 44A and 44B are rotatably supported by the corresponding support portions 24A and 24B via the shafts 50A and 50B. It can be tilted up and down so as to be close to and away from the ice making chamber 64 using 50A and 50B as supporting points.

  The first shaft 50A is not connected to the first shaft portion 52A with respect to the center of gravity of the first locking piece 54A, but is unevenly spaced apart from the portion that becomes the restricting portion 56 in the first locking piece 54A. The first shaft portion 52A is connected. That is, when the first locking piece 54A passes through the through-hole 30 of the stopper portion 28, the first shaft 50A becomes heavy without any special operation by the operator releasing his / her hand from the first shaft 50A. The regulating portion 56 side that rotates is naturally rotated around the first shaft portion 52A to convert from the first posture to the second posture. As described above, since only the first shaft 50A is moved to the front side and the operator's operation can be minimized, the mounting operation of the water tray 42 can be easily performed even in a narrow space of the ice storage chamber 18. This can be done from the front side of the body 12.

  When removing the water tray 42 from the attachment frame 22, first, the snap pin 72 is removed from the first shaft portion 52A of the first shaft 50A. As a result, in the first shaft portion 52A, the end portion protruding to the front side of the first shaft support portion 44A is opened, and therefore the second shaft 50B fixed to the second shaft support portion 44B by pulling the water tray 42 to the front side. The second shaft portion 52B is extracted from the second shaft hole 26B of the second support portion 24B, and the first shaft support portion 44A is detached from the first shaft portion 52A of the first shaft 50A. That is, the water tray 42 can be removed from the mounting frame 22 by a simple operation of removing the snap pin 72 and pulling the water tray 42 forward. As described above, since the operator's operation can be minimized, the water tray 42 can be easily removed from the front side of the box 12 even in a narrow space of the ice storage chamber 18.

  By the way, when the water tray 42 is removed, the first shaft 50A remains on the first support portion 24A. However, the first shaft 50A is set to be longer than the separation distance between the first support portion 24A and the stopper portion 28, and the first locking piece 54A and the through hole 30 are formed in the first shaft 50A in the second posture. Therefore, before the first shaft portion 52A is pulled out from the first shaft hole 26A, the movement of the restricting portion 56 to the rear side is restricted by the opening edge of the through hole 30 in the stopper portion 28. The Further, since the first shaft 50A in the free state assumes the second posture in which the restricting portion 56 faces downward due to its own weight of the first locking piece 54A, the second shaft 50A is also moved by tilting the water dish 42 or removing the snap pin 72. The posture can be maintained. That is, the first shaft 50A is held by the stopper portion 28 and does not fall off from the first support portion 24A unless the operator performs an operation of displacing from the second posture to the first posture. Therefore, when removing the water tray 42, the operator can work without considering the dropping off of the shafts 50A and 50B, and the work can be facilitated.

  Thus, the shafts 50A and 50B having an appropriate strength according to the load of the water tray 42 to be supported can be used, and the support portions 24A and 24B or the shaft support portions 44A and 44B and the shafts 50A and 50B are separated from each other. Even if it is the structure to perform, the burden of the attachment or detachment work of the water tray 42 is not increased.

(Change example)
The present invention is not limited to the configuration of the embodiment, and can be modified as follows.
(1) In the embodiment, the water tray is configured to be supported by the two shaft supports, but three or more shaft supports may be provided.
(2) In the embodiment, the stopper portion is provided only on the shaft support located at the forefront. However, the stopper may be provided on another shaft support to prevent the shaft from dropping off.
(3) In the embodiment, the first locking piece and the through hole are formed in a substantially oval shape. However, the shape of the first locking piece and the through hole is not limited to this shape. As long as the relationship is restricted, polygons such as other rectangles, ellipses, and other shapes can be adopted.
(4) As shown in FIG. 5, the restricting portion 56 of the first shaft 50A may be formed to protrude below the stopper portion 28 and the first support portion 24A in the second posture. Accordingly, the first locking piece 54A for making the first shaft 50A in the first posture is easily operated between the stopper portion 28 and the first support portion 24A. In FIG. 5, members having the same functions as those in the embodiment are denoted by the same reference numerals.
(5) As shown in FIG. 6, the structure which provides the operation part 51 in the 1st locking piece 54A of 50 A of 1st shafts can also be employ | adopted. The operation portion 51 is formed so as to protrude coaxially with the shaft portion 52A on the surface opposite to the extending surface of the first shaft portion 52A in the first locking piece 54A. Further, when the first locking piece 54A is positioned between the stopper portion 28 and the first support portion 24A, the operation portion 51 protrudes rearward from the rear surface of the stopper portion 28 through the through hole 30. Set to That is, by operating the operation portion 51 that protrudes to the rear side of the stopper portion 28, the posture displacement of the first shaft 50A can be easily performed. In FIG. 6, members having the same functions as those in the embodiment are denoted by the same reference numerals.
