Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an ice storage door structure, and more particularly to an ice storage door structure in which a door for opening and closing an ice outlet is attached to a main body side by a hinge structure.

[0002]

[Prior art]

 An ice storage or ice making machine, which is entirely box-shaped and part of which is divided into a machine room, an ice storage room, etc., is constructed as shown in FIG. That is, the ice making machine main body 1 composed of a heat insulating wall has a substantially box shape, and an ice storage chamber is formed by the front panel 2, the side panels 3, 3, the rear panel and the like. The inside of the upper front grille 5 is a machine room. The upper front parts of the side panels 3 and 3 are notched obliquely to form an ice outlet 7. A heat-insulating door 8 is attached to the side panels 3 and 3 by a well-known hinge structure 9 at the ice outlet 7. Therefore, as shown by the solid line in FIG. 7, the ice take-out port 7 can be closed by the door 8, and as shown by the chain line, lift up and stand on the front grille 5 side to open the door. It is also possible to keep 8 open.

[0003]

[Problems to be solved by the device]

 When the door 8 of the ice making machine of the above-mentioned ice storage is also tilted toward the front grill 5 side beyond the vertical line C on which the hinge 9 is provided, the door 8 leans on the front grill 5 so that the ice outlet 7 is opened. The ice can be removed from the ice storage chamber 4 with both hands. However, in order to lean the door 8 on the front grille 5, as shown in FIG. 8, an interval A is provided between the vertical line C passing through the hinge 9 and the vertical line D passing through the surface of the front grille 5. It is necessary and has a disadvantage that the volume of the ice making machine is reduced. If this interval A is made smaller, the volume will become larger, but the stability will deteriorate, and if, for example, it is accidentally touched during the removal of ice, the door 8 will inadvertently collapse in the direction of closing and may cause injury. . Therefore, in such an ice making machine, a door device provided with a lock mechanism for keeping the door open is also proposed by, for example, Japanese Utility Model Publication Nos. 55-7806 and 54-45554. However, in these door devices, since the hinge that supports the door openably and closably with respect to the main body and the lock mechanism that keeps the door open are configured separately, the number of parts increases and the structure is increased. However, there is a drawback that it becomes complicated and costly. Therefore, an object of the present invention is to provide an inexpensive ice storage door structure that has a simple structure without sacrificing the volume of the ice storage and can reliably hold the door open. I am trying.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides an ice storage in which a body provided with an ice outlet and a door for opening and closing the ice outlet are provided, and the door is attached to the body by a hinge structure. The hinge structure is composed of a first hinge portion and a second hinge portion, and one of these hinge portions is attached to the main body side, and the other is attached to the door side. The hinge part has a hinge insertion part in which a convex part is formed, the second hinge part has a hinge receiving part into which the hinge insertion part of the first hinge part is inserted, and the hinge receiving part. The convex portion of the first hinge portion is formed in the portion so that a concave portion that fits when the door is locked is formed.

[0005]

[Action]

 Since the present invention is configured as described above, the first hinge portion is attached to, for example, the upper side end of the door. At this time, attach so that the hinge insertion part is located outside and the convex part is almost parallel to the door. Next, insert the hinge receiving part of the second hinge into the hinge insertion part of the first hinge part, and attach the second hinge part to the main body side so that the direction of the concave part has a predetermined angle. . In this way, when the first hinge part and the second hinge part are attached, the hinge insertion part of the first hinge part acts as a pin in the hinge mechanism, and the hinge receiving part of the second hinge part becomes a pin hole. Play an action. There you can open and close the door. When fixing the door in the open state, open the door at a predetermined angle and then fit the convex portion of the hinge insertion portion of the first hinge portion into the concave portion of the hinge receiving portion of the second hinge portion. Then, the convex portion is held by the concave portion. Therefore, the door is also kept open at a predetermined angle. Therefore, work such as taking out ice from the ice outlet is performed. When closing the ice outlet, the convex portion of the first hinge portion is pulled out from the concave portion of the second hinge portion. Then, the hinge insertion portion of the first hinge portion becomes rotatable in the hinge receiving portion of the second hinge portion, so that the door is rotated and closed.

[0006]

【Example】

 The hinge structure according to the present invention comprises a first hinge part and a second hinge part, one hinge part of which is attached to the main body side and the other hinge part is attached to the door side. In the example, an example in which the first hinge part is attached to the door side and the second hinge part is attached to the main body side will be described. Further, although the first hinge part and the second hinge part are shown as examples in which they are attached to the door or the main body by screws, they can be attached by fixing means such as welding. The present invention can be applied to a door that opens and closes around a vertical axis, and is equally applicable to a container having a door, but an embodiment of an ice making machine that has a door that opens and closes mainly around a horizontal axis. For the door that opens and closes around the vertical axis, only a brief explanation will be given. FIG. 1 is a perspective view showing an ice making machine. The body 1 of the ice making machine according to this embodiment is also box-shaped. An ice storage chamber is formed by the front panel 2, the side panels 3 and 3, the rear panel, the bottom panel, and the like of the heat insulating structure. At the upper part of the ice storage chamber, a machine room is formed by side panels 3 ', 3', a back panel, a top panel 6, etc., and machines necessary for ice making, such as a compressor and a condenser, are arranged in this machine room. ing. A front grill 5 is provided on a part of the front panel of the machine room to ventilate the machine room.

As is clear from the above description, when the ice making machine of the present embodiment shown in FIG. 1 and the conventional example shown in FIG. 7 are compared, they are generally similar. However, the ice making machine of this embodiment does not have a portion corresponding to A of the conventional example. That is, the side panels 3 and 3 are notched in a downward slope from the lower end of the front panel 5'of the machine room toward the front. The front panel 2 is stopped up to the notched end. In this way, the ice outlet 7 is opened. The door 8 that opens and closes the ice outlet 7 is also formed of a heat insulating structure, and is hinged to the front panels 3 and 3 at the upper open ends of the front panels 3 and 3 that form the ice storage chamber.

A hinge structure for hingedly connecting the door 8 to the main body 1 is composed of a first hinge portion 20 and a second hinge portion 40. In this embodiment, as shown in FIG. The first hinge portion 20 is attached to the side portion 10 of the door 8, and the second hinge portion 40 is attached to the side surface panels 3 and 3. As shown in FIG. 3B, the first hinge portion 20 is inserted into the flat plate portion 21 for attaching to the side portion 10 of the door 8 and the hinge receiving portion 41 of the second hinge portion 40. It is composed of a hinge insertion portion 22 that acts as a pin. The hinge insertion portion 22 is composed of a fan-shaped portion 24 and a convex portion 25 located on the opposite side of the fan-shaped portion 24. Although not accurately shown in FIG. 3B, if the thickness of the flat plate portion 21 is 2.5 mm, for example, the thickness or height of the hinge insertion portion 22 is about 12 mm. It is 5 times thicker. Since it is thick as described above, the hinge insertion portion 22 has a shape in which portions X and X ′ (this symbol is not shown in the figure) shown by chain lines are cut off from a columnar body having a radius r of, for example, 12 mm. A fan-shaped portion 24 and a convex portion 25 are formed. The outer peripheral portion of the fan-shaped portion 24 is an arc-shaped sliding surface 27 having a radius r, and the outer peripheral portion of the convex portion 25 is also an arc-shaped sliding surface 27 having a radius r. The flat plate portion 21 is provided with through holes 28, 28 for mounting.

Although the embodiment of the first hinge portion 20 described with reference to FIG. 3B is applied to the right side portion of the door 8 in FIG. 1, it is attached to the left side portion. The first hinge portion is formed so as to be symmetrical when attached to the door 8. Therefore, description of the shape is omitted. Further, as will be apparent to those skilled in the art from the following description, the first and second hinge portions 20 and 40 of the present embodiment are applied to only one side portion of the door 8, and the other one is a conventionally well-known hinge. However, the intended purpose is achieved. However, it is necessary to add some play to the known hinge.

As shown in FIG. 3A, the second hinge portion 40 is made of a substantially rectangular plate material having the same plate thickness. A through hole having a substantially semicircular shape is formed near one end, and this through hole serves as a hinge receiving portion 41 into which the hinge insertion portion 22 of the first hinge portion 20 is inserted. The diameter R of the hinge receiving portion 41 is selected to be, for example, 12.5 mm, which is larger than the radius 12 mm of the hinge insertion portion 22 by about 0.5 mm. Therefore, the hinge insertion portion 22 of the first hinge portion 20 acts as a pin, and the hinge receiving portion 41 of the second hinge portion 40 acts as a pin hole. From the hinge receiving portion 41, a concave portion 42 cut out in parallel extends. The width of the concave portion 42 is slightly larger than the width of the convex portion 25 of the first hinge portion 20. Further, the hinge receiving portion 41 and the concave portion 42 are connected by a smooth curve RL. It should be noted that elongated holes 43, 43 are formed in the longitudinal direction near the side opposite to the hinge receiving portion 41.

Next, the operation of the above embodiment will be described. First, as shown in FIG. 2A, the first hinge portion 20 is attached to the upper end of the side portion 10 of the door 8. At this time, the hinge insertion portion 22 is located outside and the convex portion 25 is substantially parallel to the door 8, and the screw 29 is used by using the through holes 28 of the flat plate portion 21 of the first hinge portion 20. , 29 stop. Next, as shown in FIG. 2B, the hinge receiving portion 41 of the second hinge 40 is inserted into the hinge insertion portion 22 of the first hinge portion 20, and the second hinge portion 40 is placed on the side surface. The screws 44 and 44 are similarly fixed to the panel 3. At this time, the concave portion 42 is attached so that the direction of the concave portion 42 forms a predetermined angle θ with the opening edge 11 of the ice outlet 7. The adjustment of the attachment angle θ uses the elongated holes 43, 43 of the second hinge portion 40.

The state of attachment in this way is shown in FIG. That is, (a) of FIG. 4 shows a state in which the door 8 closes the ice outlet 7, and (b) shows an open state. Since the hinge insertion portion 22 of the first hinge portion 20 acts as a pin in the hinge mechanism and the hinge receiving portion 41 of the second hinge portion 40 acts as a pin hole, the door 8 is the main body, that is, the side panel 3, It can be opened and closed with respect to 3. In order to open the door 8 and fix it in that position, open the door 8 at a predetermined angle and then lower it in the direction indicated by the arrow E in FIG. The convex portion 25 of the insertion portion 22 is fitted into the concave portion 42 of the second hinge portion 40. Then, a force as shown in FIG. 5 acts between the convex portion 25 and the concave portion 42, and the door 8 is held at a predetermined angle. That is, since the door 8 tends to fall in the closing direction due to the action of gravity in the illustrated example, a force acts on the tip of the convex portion 25 in the direction indicated by the arrow A and at the base in the direction indicated by B. However, since these forces are received by the inner wall of the concave portion 42, the door 8 is held in an open state at a predetermined angle. When closing the door 8, the door 8 is pulled up in the direction indicated by the arrow H in FIG. 4B, and the convex portion 25 is pulled out from the concave portion 42. Then, the hinge insertion portion 22 of the first hinge portion 20 comes into a state in which it can be rotated within the hinge receiving portion 41 of the second hinge portion 40, so that the hinge insertion portion 22 can be closed.

As described above, according to this embodiment, only by changing the shapes of the hinge insertion portion 22 and the hinge receiving portion 41 of the hinge structure, in addition to the hinge function of opening and closing the door 8, the lock is achieved. Since it also has a function to operate, it does not require a space for leaning the door 8 unlike the conventional case. That is, the ice machine body 1 can be enlarged. Also, since the number of parts does not increase simply by changing the shape, there is no increase in cost. Further, since the first and second hinge portions 20 and 40 are attached by the screw means 29 and 44, there are no problems such as welding distortion and rust due to welding, and maintenance and assembly are simplified.

Next, another embodiment of the hinge insertion portion 22 of the first hinge portion 20 will be described with reference to FIG. As will be apparent from the above description, the hinge insertion portion 22 is not particularly limited in shape as long as it has a hinge action and a lock action in cooperation with the hinge receiving portion 41. In the embodiment shown in FIG. 6A, the fan-shaped portion 32 is formed in a substantially semicircular shape. And the convex part 35 has extended in parallel from the bottom. The peripheral edge of the fan-shaped portion 32 and the tip of the convex portion 25 form sliding surfaces 27, 27. Obviously, the area of the fan-shaped portion 32 can be increased or decreased as shown by the chain line. FIG. 6B shows an example in which the area of the fan-shaped portion 32 is small and the width is the same as that of the convex portion 25. In the embodiment shown in FIG. 6C, the lower side of the fan-shaped portion 32 extends to the convex portion 35, and as a result, the convex portion 35 is shortened. Even if the length is shortened in this way, the same operation can be performed by slightly modifying the shape of the hinge receiving portion 41 of the second hinge portion 40. Another embodiment in which the convex portion 35 is shortened is shown in FIG. According to this embodiment, the lower side of the fan-shaped portion 32 is cut up obliquely, and as a result, the arcuate sliding surface 27 is reduced. It is clear that the embodiment shown in (a) to (d) of FIG. 6 has the same action and effect as the embodiment shown in (b) of FIG.

FIG. 6 shows an embodiment having a hinge action about the vertical axis. That is, the hinge structure is composed of a vertical shaft 50 and a ring-shaped bearing 51 that receives the vertical shaft 50. The vertical shaft 50 is formed with an outwardly projecting projection 52, At a part of the upper edge of 51, a concave portion 53 that is depressed when the convex portion 52 rotates a predetermined amount is cut out. A double door that is not shown in the figure is attached to, for example, the vertical shaft 50, and the bearing 51 is attached to the main body side. Therefore, when the door is rotated around the bearing 51 by a predetermined amount and the convex portion 52 of the vertical shaft 50 is dropped into the concave portion 53 of the bearing 51, the door is locked at that position.

[Effect of device]

 According to the present invention, the first hinge part has a hinge insertion part in which a convex part is formed, and the second hinge part has a hinge receiving part into which the hinge insertion part of the first hinge part is inserted. At the same time, since the convex portion of the first hinge portion and the concave portion that fits when the door is locked are formed in the hinge receiving portion, the convex portion of the first hinge portion fits into the concave portion of the second hinge portion. Only by doing so, the effect peculiar to the present invention that the door can be surely held in the open state can be obtained without sacrificing the volume of the ice making machine body. Further, since the first hinge portion is provided with the convex portion and the second hinge portion is provided with the concave portion, the hinge function and the locking function are obtained with a small number of parts, a simple structure, and an inexpensive structure.
